Description

Method for realizing interconnection between digital subscriber line network and wireless communication network

Technical Field

The invention relates to the technical field of Digital Subscriber Line (DSL) networks and wireless communication networks, in particular to a method for realizing interconnection of a Digital Subscriber Line network and a wireless communication network.

Background

The 3G and 2G wireless communication systems adopt a similar structure, and the system architecture thereof is shown in fig. 1. In the whole 3G or 2G wireless communication Network, a Radio Access Network (RAN) and a Core Network (CN) are included. Wherein the radio access network is adapted to handle all radio related functions and the CN is adapted to handle all voice calls and data connections within the wireless communication system and to implement switching and routing functions with external networks. The CN is logically divided into a Circuit Switched Domain (CS) and a packet Switched Domain (PS). The RAN, CN and Mobile Station (MS) together form the entire 3G or 2G wireless communication network.

In the RAN, a Base Station (BS) and a Base Station Controller (BSC) are typically included. The BS IS called a Base Transceiver Station (BTS) in GSM/GPRS/IS-95/CDMA2000, and IS called a node B (node B) in WCDMA/TD-SCDMA; the BSC is called a Radio Network Controller (RNC) in WCDMA; in CDMA2000, a Packet Control Function (PCF) logical entity is included, which is located between the BSC and a Packet Data Serving Node (PDSN), and provides Packet Data service support, which may be located with the BSC or separately as part of the radio access network.

In the WiMAX Network defined by 802.16, the RAN is referred to as an Access Service Network (ASN) and the CN is referred to as a Connectivity Service Network (CSN), and a system reference architecture thereof is shown in fig. 2. Wherein, the BS can be directly accessed to the CSN through an access service gateway (ASN-GW), and the BS and the ASN-GW can be physically placed on the same entity or respectively and independently placed; alternatively, the BS may be divided into two network elements, BTS and BSC as in a 3G/2G network.

The above networks all belong to wireless communication networks, and a brief introduction is made below to a user digital line network.

The DSL network architecture is evolving from PPP over ATM to an IP QoS enabled architecture based on Ethernet aggregation and connection (Ethernet aggregation and connection), in which context the generic reference architecture for DSL networks is shown in fig. 3.

Referring to fig. 3, T is a reference point between a Terminal Equipment (TE) and a DSL Modem (DSL Modem, abbreviated as Modem) in a Customer Premise Network (CPN); u is a reference point between a DSL Modem and an access point Digital Subscriber Line Access Multiplexer (DSLAM); in an Access Network (Access Network), an Aggregation Network (Aggregation Network) is arranged between a DSLAM (digital subscriber line Access) and a Broadband Access Server (BRAS), and V is an Ethernet Aggregation reference point between the DSLAM and the BRAS in the Access Network; a10 is a reference point between an access Network and a Service Provider (SP) that can connect either an Application Service Provider (ASP) to a Network Service Provider (NSP) that owns the access Network or, in a roaming scenario, the NSP to a visited access Network. The CPN network and the access network are interconnected by adopting DSL access technology.

At present, the interconnection between the 3G/2G/WiMAX-based wireless communication network and the DSL network belongs to a branch of Fixed Mobile Convergence (FMC), and how to implement the interconnection between the DSL network and the wireless communication network is a problem to be solved.

Detailed Description

The idea of the invention is as follows: the functional division between a first Wireless adapter WA1 (WA) and a second Wireless adapter WA2, WA1 and WA2 is defined as follows:

for WCDMA, GSM, GPRS and TD-SCDMA networks, WA1 and WA2 have the following modes:

(1) WA1 or WA2 is equivalent to RNC or BSC, WA1 and WA2 do not exist simultaneously; that is to say WA1 or WA2 is provided with a first function for managing base stations;

(2) WA1 or WA2 corresponds to RNC + SGSN (serving GPRS support node) or BSC + MSC (mobile switching center), WA1 and WA2 do not exist at the same time; that is, WA1 or WA2 has a first function for managing a base station and a second function for control management of a subscriber station; a subscriber station is here a generic term for all end users.

For a 2G or 3G network, the subscriber station refers to a mobile station, and for a WiMAX network, the subscriber station refers to a mobile station or a fixed terminal.

The interconnection method provided by the invention is used as wireless extension of wired access of a copper wire broadband network, and is suitable for fixed wireless, nomadic, portable and mobile access applications. Meanwhile, an evolution approach is provided for DSL network operators to develop wireless networks.

The following specifically describes the implementation process by taking the PS domain of WCDMA as an example, with reference to the accompanying drawings.

The first interconnection scheme is as follows:

as shown in fig. 4a, 4b and 4c, three embodiments of the present invention are applied, and the three embodiments are characterized in that: the BS or WA1 in the wireless communication network is interconnected with the reference point U in the existing general DSL network through the DSL Modem, and the wireless communication network WA2 or CN is interconnected with the BRAS at the reference point A10, thereby realizing the interconnection of the wireless communication network and the DSL network. The interconnection method has the advantages that the construction of the wireless communication access network, such as the 3G/2G/WiMAXW access network, utilizes the laid resources of the original DSL network as much as possible, thereby reducing the construction cost of the wireless communication access network, and the interconnection belongs to a tight coupling scheme. The three embodiments described above differ in that only WA2 is present in the embodiment shown in fig. 4a, only WA1 is present in the embodiment shown in fig. 4b, and both WA1 and WA2 are present in the embodiment shown in fig. 4 c.

Referring to fig. 4a, 4b, and 4c, when data communication is performed, the UE first establishes a Radio Resource Control (RRC) connection through a control plane protocol stack, and starts to establish a Radio Access Bearer (RAB) after negotiating with a core network, where the RAB establishment process is accompanied by establishment of a user plane Radio Bearer (RB). After the RAB establishment is successful, the user can transmit data through the established user plane bearer. The compression and decompression functions of the Packet Data Convergence Protocol (PDCP) may or may not be enabled. The signaling establishment procedure is that after the RRC connection between the UE and the UMTS Terrestrial Radio Access Network (UTRAN) is successfully established, the UE establishes a signaling connection with the CN through the RNC, which is also called a "non-access stratum (NAS) signaling establishment procedure" and is used for signaling interaction NAS information of the UE and the CN, such as authentication, service request, connection establishment, and the like. The following describes the transmission process of user plane and control plane data by taking the compression and decompression functions as an example.

The Radio Network Layer (RNL) of the Uu interface includes a PDCP (packet data convergence protocol), a Radio Link Control (RLC) and a Media Access Control (MAC) in a user plane, and includes an RRC, an RLC and an MAC in a control plane.

Referring to fig. 4a, a base station BS for wireless access, control and management is interconnected with a reference point T in a DSL network, and data in a wireless communication network is accessed to a wired network through a DSL Modem; a WA2 is provided, interconnecting the WA2 with a BRAS over reference point a10, and accessing data in the DSL network to the core network. Thereby realizing the interconnection of the wired network and the wireless network. In this interconnection mode, the network element BS and the DSL Modem may be separated or integrated, and the network element BRAS and WA2 may also be logically separated or integrated. The term "separate" means that two network elements are independent of each other, and the term "integrated" means that two or more network elements are integrated into one network element, and the like is used hereinafter.

For fig. 4a, there are three implementation modes, which are:

mode (1): WA2 corresponds to the function of an RNC, namely WA2 ═ RNC;

mode (2): WA2 corresponds to the functions of RNC and SGSN, namely WA2 ═ RNC + SGSN;

mode (3): WA2 corresponds to the functions of RNC, SGSN and GGSN, namely WA2 ═ RNC + SGSN + GGSN.

The above three modes are described separately from the protocol stack perspective.

Reference is made to fig. 5 and fig. 6, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (1) in the embodiment shown in fig. 4 a. Based on the protocol stack structure:

for uplink user plane data: the application layer data of the UE is encapsulated into a data packet and then sent to a Radio Network Layer (RNL), and the data packet may be a user IP data packet or a PPP protocol packet. The RNL compresses the packet header, adds a header specified by a protocol, such as an RLC/MAC header, and transmits the header to a Radio Frequency Layer (RFL) of a physical Layer, and the RFL performs operations such as coding and modulation on the received packet and transmits the packet to the UTRAN through a Uu interface. After receiving the data packet, the RFL of the Node B in UTRAN encapsulates the data packet into a Frame Protocol (FP) frame, adds an IP header to the FP frame, i.e., after IP processing, sends the processed IP packet to WA2 through the Iub interface. An IP packet composed of an IP header and an FP frame (i.e., an IP packet payload) is referred to herein as an FP/IP frame, and the following description is similar thereto.

FP/IP frames are carried directly over the DSL network due to the Iub interface frame protocol between Node B and WA 2. For example, a two-layer bridging technology, such as ethernet bridging, may be used between Node B and WA2 to implement transmission, where the DSL Modem and DSLAM are both two-layer network elements; or, a three-layer routing technology, such as IP three-layer routing, is used between Node B and WA2 to implement transmission, and at this time, the DSL Modem and DSLAM both implement transmission for three-layer network elements. For the protocol stack shown in fig. 5, the specific implementation process is as follows:

node B divides FP/IP frame into Ethernet (ETH) frame, and sends it to DSL Modem through cable in Ethernet physical layer PHY; the Ethernet PHY of the DSL Modem converts the received data into an ETH frame, then carries out DOCSIS modulation processing to convert the ETH frame into a DSL physical frame suitable for twisted pair transmission in a cable network, and transmits the DSL physical frame to the DSLAM through a twisted pair; carrying out DOCSIS demodulation processing on DSL physical frames of the DSLAM to obtain ETH frames, and then transmitting the ETH frames to the BRAS through an Ethernet physical layer PHY loaded between the DSLAM and the BRAS; the BRAS ethernet PHY converts the received Data into an ETH frame again, performs ethernet MAC processing on the ETH frame to obtain an IP packet, performs Data Link Layer (LNK) encapsulation on the IP packet again, and then the BRAS sends the physical Layer PHY, which carries the encapsulated Data between the BRAS and WA2, to WA2 for further processing.

At this time, the WA2 corresponds to the function of the RNC, and thus is exactly the same as the processing of the conventional RNC user plane, specifically: WA2 receives data through PHY, gets FP/IP frame after LNK decapsulation to the received data, converts the FP/IP frame into FP frame, because Iub interface frame protocol FP/IP frame between Node B and WA2 is directly loaded on DSL network, at this moment, it can be regarded as WA2 gets FP/IP frame directly from Iub interface, gets data packet in RNL after decapsulation of the FP/IP frame, then WA2 sends the data packet to network element in CN through GTP tunnel after making Iu interface transmission network layer and wireless network layer process. The processing of the transmission network layer of the Iu interface includes processing of a GTP user plane (GTP-U), UDP, IP, LNK, and PHY layers, and the wireless network layer of the Iu interface is Iu UP protocol processing for transmitting user data related to RAB.

At CN, SGSN makes Iu interface transmission network layer and wireless network layer processing, and sends the received data from GTP tunnel to GGSN through Gn interface. The data received by the GGSN from the GTP tunnel of the Gn interface is the user IP data packet or PPP protocol packet of the UE, and the GGSN sends the user IP data packet or PPP protocol packet to the external network through the Gi interface. That is, at this time, the processing procedure of the CN network is completely the same as the existing processing procedure.

Similarly, the UE receives the data packet addressed to the UE by the core network through the reverse procedure.

For uplink control plane data: the UE side encapsulates the signaling message, such as GMM, SM, SMS message or signaling message of RRC layer, into data packet in RNL, and sends the data packet to RFL of physical layer after adding the header specified by protocol, such as RLC/MAC header, and the RFL performs operations such as coding modulation to the received data packet and sends the data packet to UTRAN through Uu interface. After receiving the data packet, the RFL of the Node B in UTRAN encapsulates the data packet into an Iub interface radio network layer frame, for example, an FP frame, and transmits the network layer, for example, IP/ETH/PHY, through the Iub interface to carry the data packet to WA 2. The radio network layer of the Iub interface between Node B and WA2 and the IP layer or Signaling Bearer layer of the transport network layer (IP layer for FP and Signaling Bearer for NBAP, the same applies below) are directly carried on top of the DSL network. The radio network layer includes an FP or NodeB application Protocol (NBAP, NodeB application Protocol, NBAP frame only existing between the Node B and the RNC), and the signaling bearer layer includes a Simple Control Transmission Protocol (SCTP) layer and an IP layer. For example, a two-layer bridging technology, such as ethernet bridging, may be used between Node B and WA2 to implement transmission, where DSL Modem and DSLAM are both two-layer network elements; or, a three-layer routing technology, such as IP three-layer routing, is used between Node B and WA2 to implement transmission, and at this time, the DSL Modem and DSLAM both implement transmission for three-layer network elements. For the protocol stack shown in fig. 6, the specific implementation process is as follows:

node B divides FP/IP frame or NBAP/SCTP/IP frame (IP packet obtained after NBAP, SCTP and IP processing) into ETH frame, and sends to DSL Modem through cable in Ethernet physical layer PHY; the Ethernet PHY of the DSL Modem converts the received data into an ETH frame, then carries out DOCSIS modulation processing to convert the ETH frame into a DSL physical frame suitable for twisted pair transmission in a cable network, and transmits the DSL physical frame to the DSLAM through a twisted pair; carrying out DOCSIS demodulation processing on DSL physical frames of the DSLAM to obtain ETH frames, and then transmitting the ETH frames to the BRAS through an Ethernet physical layer PHY loaded between the DSLAM and the BRAS; the BRAS ethernet PHY converts the received data into an ETH frame again, performs ethernet MAC processing on the ETH frame to obtain an IP packet, performs LNK encapsulation on the IP packet again, and then the BRAS sends the physical layer PHY, which carries the encapsulated data between the BRAS and the WA2, to the WA2 for further processing.

At this time, the WA2 is equivalent to the function of the RNC, so it is exactly the same as the processing of the conventional RNC control plane, specifically: WA2 receives data through PHY, and gets FP/IP frame or Signaling Bearer layer Signaling Bearer data after LNK decapsulation is done to the received data. For FP/IP frame, remove the processing of IP header and get FP frame, for signaling bearing layer data to get NBAP frame after SCTP and IP processing, because Iub interface frame protocol FP/IP frame or NBAP between Node B and WA2 is directly loaded on DSL network, at this moment, WA2 can be regarded as getting FP/IP frame or NBAP frame directly from Iub interface. If WA2 receives the NBAP frame, processing the NBAP frame accordingly; if WA2 receives the FP/IP frame, it removes the IP header from the FP/IP frame to obtain the FP frame, and de-encapsulates the FP frame to obtain the data packet in RNL, and then WA2 processes the data packet by the transport network layer and the radio network layer of Iu interface and sends it to the network element in CN. The processing of the transport network layer of the Iu interface comprises the processing of SCCP, Signaling Bearer, LNK and PHY layers, and the processing of the radio network layer of the Iu interface comprises the processing of RANAP.

At CN, SGSN makes the transmission network layer and wireless network layer process of Iu interface to obtain the signaling message of UE side, such as GMM, SM, SMS message, and then continues the follow-up process according to the existing mode. That is, at this time, the processing procedure of the CN network is completely the same as the existing processing procedure.

Similarly, the UE receives a signaling message addressed to the UE by the core network through the reverse procedure.

Reference is made to fig. 7 and 8, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for another embodiment of mode (1) in the embodiment shown in fig. 4 a. The differences with the protocol stacks shown in fig. 5 and 6 are: node B and DSL Modem are integrated into a logic entity, and it is called "Node B + DSL Modem". The SGSN and GGSN in the core network are integrated into a new network element, and the new network element is called an IGSN (integrated GPRS support node). Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing of fig. 5 and 6 will be described below, and the same parts will not be described again.

For uplink user plane data: after UE sends data to UTRAN through Uu interface, Node B + DSL Modem in UTRAN receives data packet and packs data packet into FP frame, adds IP head to FP frame, and sends processed IP packet to WA2 through Iub interface. The Iub interface frame protocol FP/IP frame between the Node B + DSL Modem and WA2 is directly carried on the DSL network, specifically, a two-layer bridging technology or a three-layer routing technology can be adopted. That is, the Node B + DSL Modem divides the FP/IP frame into ETH frame, then the ETH frame is converted into DSL physical frame suitable for the twisted pair transmission in the cable network by the DOCSIS modulation process, and the DSL physical frame is sent to the DSLAM through the twisted pair. And then the same as the process of fig. 5. That is, compared to fig. 5, the user plane data can reach WA2 via the DSLAM and BRAS.

At CN, IGSN does Iu interface transmission network layer and wireless network layer processing, the data received from GTP tunnel is user IP data packet or PPP protocol packet of UE, IGSN sends to external network in user IP data packet or PPP protocol packet form.

For uplink control plane data: after the UE side sends the signaling message to UTRAN through Uu interface, RFL of Node B + DSL Modem in UTRAN receives the data packet and packs the data packet into Iub interface wireless network layer frame, for example, to be FP frame, and sends WA2 through Iub interface transmission network layer bearing. The radio network layer, such as FP or NBAP, of the Iub interface between Node B + DSL Modem and WA2, and the IP layer or signaling bearer layer of the transport network layer are carried directly over the DSL network. Specifically, a two-layer bridging technique or a three-layer routing technique can be adopted. That is, the Node B + DSL Modem divides the FP/IP frame or NBAP/SCTP/IP frame into ETH frame, then the ETH frame is converted into DSL physical frame suitable for the twisted pair transmission in the cable network by the DOCSIS modulation process, and the DSL physical frame is sent to the DSLAM through the twisted pair. And then the same as the process of fig. 6. In comparison with fig. 6, the user plane data is accessible to WA2 via DSLAM and BRAS.

At CN, IGSN makes the transmission network layer and wireless network layer process of Iu interface to obtain the signaling message of UE side, such as GMM, SM, SMS message, and then continues the follow-up process according to the existing mode.

Reference is made to fig. 9 and fig. 10, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (2) in the embodiment shown in fig. 4 a. The differences with the protocol stacks shown in fig. 7 and 8 are: WA2 corresponds to the functions of an RNC and SGSN. Thus, for CN, only GGSN process is needed, and SGSN process is no longer needed. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing of fig. 7 and 8 will be described below, and the same parts will not be described again.

For uplink user plane data: WA2 receives data through PHY, gets FP/IP frame after LNK decapsulation to the received data, converts the FP/IP frame into FP frame, because Iub interface frame protocol FP/IP frame between Node B + DSL Modem and WA2 is directly carried on DSL network, at this moment, can regard as WA2 to get FP/IP frame directly from Iub interface, get data packet in RNL after decapsulating the FP/IP frame, then WA2 sends the data packet to network element in CN through GTP tunnel after making Gn interface protocol stack processing. And the Gn interface protocol stack processing comprises the processing of a GTP user plane (GTP-U), UDP, IP, LNK and PHY layers.

At CN, GGSN makes Gn interface protocol stack treatment, the data received from GTP tunnel is user IP data packet or PPP protocol packet of UE, GGSN sends the user IP data packet or PPP protocol packet to external network.

For uplink control plane data: WA2 receives data through PHY, gets FP/IP frame or signaling carrying layer data after LNK decapsulation to the received data, gets FP frame after removing IP head for FP/IP frame, gets NBAP frame after SCTP and IP process for signaling carrying layer data, because Iub interface frame protocol FP/IP frame or NBAP between Node B + DSL Modem and WA2 is carried on DSL network directly, therefore, WA2 can be regarded as getting FP/IP frame or NBAP frame directly from Iub interface at this time, if WA2 receives NBAP frame, then carries on corresponding process to NBAP frame; if the WA2 receives the FP/IP frame, decapsulate the FP/IP frame to obtain a data packet in the RNL, and after the processing by the RNL layer, the WA2 obtains a signaling message at the UE side, such as a GMM, an SM, an SMs message, or a signaling message at the RRC layer, and performs corresponding processing, such as establishing a connection, a measurement report, etc., that is, the WA2 completes the control plane functions of the RNC and the SGSN. The user plane GTP tunnel is established, maintained or released between WA2 and GGSN via the Gn interface control plane GTP protocol. The Gn interface protocol stack processing comprises GTP control plane (GTP-C), UDP, IP, LNK and PHY layer processing.

Of course, when actually implementing the mode (2) in the embodiment shown in fig. 4a, the Node B and the DSL Modem may also be independent from each other, and each Node B and the DSL Modem may also be an independent logic entity, at this time, the processing of this part is the same as the processing procedure shown in fig. 5 and fig. 6, and details are not described here again.

Reference is made to fig. 11 and 12, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (3) in the embodiment shown in fig. 4 a. The differences with the protocol stacks shown in fig. 7 and 8 are: WA2 corresponds to the functions of an RNC, SGSN and GGSN. Thus, the CN does not need to perform processing of the SGSN and GGSN, and other processing is as usual. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing of fig. 7 and 8 will be described below, and the same parts will not be described again.

For uplink user plane data: WA2 receives data through PHY, gets FP/IP frame after LNK decapsulation to the received data, converts the FP/IP frame into FP frame, because Iub interface frame protocol FP frame between Node B + DSL Modem and WA2 is directly carried on DSL network, at this moment, it can be regarded as WA2 directly gets FP/IP frame from Iub interface, gets data packet in RNL after decapsulation of the FP/IP, then WA2 routes the data packet to external network through CN.

In CN, no more processing is done for SGSN and GGSN, only routing function is done.

For uplink control plane data: WA2 receives data through PHY, gets FP/IP frame or signaling carrying layer data after LNK decapsulation to the received data, gets FP frame after removing IP head for FP/IP frame, gets NBAP frame after SCTP and IP process for signaling carrying layer data, because Iub interface frame protocol FP/IP frame or NBAP frame between Node B + DSL Modem and WA2 is carried on DSL network directly, at this time, it can be regarded as WA2 gets FP/IP frame or NBAP frame from Iub interface directly, if WA2 receives NBAP frame, then carries on corresponding process to NBAP frame; if WA2 receives the FP/IP frame, decapsulate the FP/IP frame to obtain a data packet in RNL, after RNL layer processing, WA2 obtains a signaling message of UE side, such as GMM, SM, SMs message or a signaling message of RRC layer, and performs corresponding processing, such as establishing connection, measurement report, etc., i.e. WA2 completes the control plane function of RNC, SGSN and GGSN.

Of course, when actually implementing the mode (3) in the embodiment shown in fig. 4a, the Node B and the DSL Modem may also be independent from each other, and each may be an independent logic entity, and at this time, the processing of this part is the same as the processing procedure shown in fig. 5 and fig. 6, and is not described again here.

Referring to fig. 4b, a WA1 is provided in a base station BS for wireless access, control and management, the BS is interconnected with a reference point T in a DSL network through a WA1, and data in a wireless communication network is accessed to a wired network through a DSL Modem; the BRAS in the wired network accesses the data in the DSL network to the core network through the reference point a10, so as to realize interconnection between the wired network and the wireless network. In this interconnection mode, the network elements BS, WA1 and DSL Modem may be logically separated or integrated.

For fig. 4b, there are two more implementation modes, respectively:

mode (4): WA1 corresponds to the function of an RNC, namely WA1 ═ RNC;

mode (5): WA1 corresponds to the functions of an RNC and SGSN, namely WA1 ═ RNC + SGSN.

The above two modes are described separately from the protocol stack perspective.

Reference is made to fig. 13 and fig. 14, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (4) in the embodiment shown in fig. 4 b. In this example, Node B is provided with WA1, and Node B provided with WA1 is referred to as Node B + WA 1.

For uplink user plane data: the application layer data of the UE is encapsulated into a data packet and sent to the RNL, where the data packet may be a user IP data packet or a PPP protocol packet. The RNL compresses the packet header, adds a header specified by a protocol, such as an RLC/MAC header, and then sends the header to the RFL of the physical layer, and the RFL performs operations such as coding modulation on the received packet and then sends the packet to the UTRAN through a Uu interface. Because WA1 is equivalent to the function of RNC, RFL of Node B + WA1 in UTRAN, after receiving the data packet, sequentially removes the protocol header, and after re-combination and header decompression processing, forwards the data packet to CN through Iu interface via GTP tunnel, and the GTP tunnel protocol, UDP and IP between WA1 and CN in Node B are directly carried over DSL network. Specifically, a two-layer bridging technology or a three-layer routing technology may be adopted between the WA1 and the SGSN in the CN to implement transmission, and for the protocol stack shown in fig. 13, the specific implementation process is as follows:

node B + WA1 divides GTP/UDP/IP frame (IP packet processed by GTP, UDP and IP) into ETH frame, and sends it to DSL Modem through cable at Ethernet physical layer PHY; the Ethernet PHY of the DSL Modem converts the received data into an ETH frame, then carries out DOCSIS modulation processing to convert the ETH frame into a DSL physical frame suitable for twisted pair transmission in a cable network, and transmits the DSL physical frame to the DSLAM through a twisted pair; carrying out DOCSIS demodulation processing on DSL physical frames of the DSLAM to obtain ETH frames, and then transmitting the ETH frames to the BRAS through an Ethernet physical layer PHY loaded between the DSLAM and the BRAS; the BRAS converts the received data into an ETH frame again, performs Ethernet MAC processing on the ETH frame to obtain an IP packet, performs LNK encapsulation on the IP packet again, and then loads the encapsulated data on a physical layer PHY between the BRAS and the CN to be sent to the CN for further processing.

At CN, SGSN makes Iu interface transmission network layer and wireless network layer processing, and receives data from GTP tunnel and sends the data to GGSN via Gn interface. The data received by the GGSN from the GTP tunnel of the Gn interface is the user IP data packet or PPP protocol packet of the UE, and the GGSN sends the user IP data packet or PPP protocol packet to the external network through the Gi interface. That is, at this time, the processing procedure of the CN network is completely the same as the existing processing procedure.

For uplink control plane data: the UE side encapsulates the signaling message, such as GMM, SM, SMS message or signaling message of RRC layer, into data packet in RNL, and sends the data packet to RFL of physical layer after adding the header specified by protocol, such as RLC/MAC header, and the RFL performs operations such as coding modulation to the received data packet and sends the data packet to UTRAN through Uu interface. After receiving the data packet, the RFL of Node B + WA1 in UTRAN removes the protocol header from the data packet in turn, recombines and combines them, sends the data to the RRC protocol of RNL, analyzes the signaling message, and performs corresponding processing, such as connection establishment, measurement report, etc. But for GMM/SM/SMs messages, Node B + WA1 will directly hand the corresponding message over the radio network layer (e.g., NANAP) and transport network layer of the Iu interface to the CN process. The transmission network layer comprises SCCP/M3UA/SCTP/IP/LNK/PHY, wherein M3UA/SCTP/IP is Signalig Bearer in the figure. The wireless network layer of the Iu interface between WA1 and CN in Node B, such as NANAP, and the transport network layer, such as SCCP/M3UA/SCTP/IP, are directly carried on the DSL network, specifically, a two-layer bridging technique or a three-layer routing technique is adopted between WA1 and SGSN in CN to implement transmission. For the protocol stack shown in fig. 14, the specific implementation process is as follows:

node B + WA1 divides RANAP/SCCP/M3UA/SCTP/IP frame (IP packet processed by RANAP, SCCP, M3UA, SCTP and IP) into Ethernet ETH frame, and sends to DSL Modem through cable at Ethernet physical layer PHY; the Ethernet PHY of the DSL Modem converts the received data into an ETH frame, then carries out DOCSIS modulation processing to convert the ETH frame into a DSL physical frame suitable for twisted pair transmission in a cable network, and transmits the DSL physical frame to the DSLAM through a twisted pair; carrying out DOCSIS demodulation processing on DSL physical frames of the DSLAM to obtain ETH frames, and then transmitting the ETH frames to the BRAS through an Ethernet physical layer PHY loaded between the DSLAM and the BRAS; and converting the received data into an ETH frame again, carrying out Ethernet MAC processing on the ETH frame to obtain an IP packet, carrying out LNK encapsulation on the IP packet again, and then carrying out further processing on the encapsulated data by the BRAS on a physical layer PHY (physical layer) between the BRAS and the CN by the BRAS.

At CN, SGSN makes the processing of transmission network layer and wireless network layer of Iu interface, and obtains GMM, SM or SMS message from RANAP, then makes the following processing according to the existing mode.

Reference is made to fig. 15 and 16, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for another embodiment of mode (4) in the embodiment shown in fig. 4 b. The differences from the protocol stacks shown in fig. 13 and 14 are: NodeB + WA1 is integrated with DSL Modem into a logical entity, and it is called "NodeB + WA1+ DSLModem". Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 13 and 14 will be described below, and the same parts will not be described again.

For uplink user plane data: after UE sends data to UTRAN through Uu interface, RFL of Node B + WA1+ DSL Modem in UTRAN receives data packet, then removes protocol header in turn, after recombination and header compression process, transmits data packet to CN through GTP tunnel through Iu interface, GTP tunnel protocol, UDP and IP between WA1 and CN are carried on DSL network directly. The specific implementation process is as follows:

node B + WA1+ DSL Modem divides GTP/UDP/IP frame into Ethernet ETH frame, then carries out DOCSIS modulation processing to convert into DSL physical frame suitable for twisted pair transmission in cable network, and sends to DSLAM via twisted pair. Thereafter, the same as the processing of fig. 13. That is, compared to fig. 13, the subscriber data can reach the CN via the DSLAM and BRAS.

For uplink control plane data: after the UE side sends the signaling message to UTRAN through Uu interface, RFL of Node B + WA1+ DSL Modem in UTRAN receives the data packet and removes the protocol header in turn, through recombination and combination, sends the data to RRC protocol of RNL, analyzes the signaling message, and processes correspondingly, such as connection establishment, measurement report, etc. But for GMM/SM/SMs messages, Node B + WA1 will directly hand the corresponding message over the radio network layer (e.g., NANAP) and transport network layer of the Iu interface to the CN process. Wherein, the transmission network layer of the Iu interface comprises SCCP/M3UA/SCTP/IP/LNK/PHY, wherein M3UA/SCTP/IP is SignalingBearer in the figure. The wireless network layer (such as NANANANA) and the transmission network layer (such as SCCP/M3UA/SCTP/IP) of the Iu interface between WA1 and CN in Node B are directly carried on the DSL network, and the specific implementation process is as follows:

node B + WA1+ DSL Modem segments RANAP/SCCP/M3UA/SCTP/IP packet into Ethernet ETH frame, then performs DOCSIS modulation processing to convert into DSL physical frame suitable for twisted-pair transmission in cable network, and sends to DSLAM via twisted-pair. Thereafter, the same as the processing of fig. 14. That is, compared to fig. 14, the control plane data reaches the CN via the DSLAM and BRAS.

In addition, for the embodiments shown in fig. 13 to 16, the SGSN and the GGSN in the core network may be combined into a new network element, and the new network element is referred to as an IGSN. The IGSN processing is the same as the processing described in fig. 7 and 8, and is not described here again.

Reference is made to fig. 17 and fig. 18, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (5) in the embodiment shown in fig. 4 b. The differences from the protocol stacks shown in fig. 13 and 14 are: WA1 corresponds to the functions of an RNC and SGSN. Thus, for CN, only GGSN process is needed, and SGSN process is no longer needed. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 13 and 14 will be described below, and the same parts will not be described again.

For uplink user plane data: after UE sends data to UTRAN through Uu interface, WA1 is equivalent to RNC and SGSN function, therefore, after RFL of Node B + WA1 in UTRAN receives data packet, protocol header is removed in turn, after recombination and header decompression process, data packet is forwarded to CN through Gn interface through GTP tunnel, and GTP tunnel protocol, UDP and IP between WA1 and CN are carried directly on DSL network.

For uplink control plane data: after the UE side sends the signaling message to UTRAN through Uu interface, because WA1 is equivalent to RNC and SGSN function, RFL of Node B + WA1 in UTRAN receives the data packet and removes the protocol header in turn, through recombination and combination, sends the data to RNL, after RNL layer processing, obtains the signaling message of UE side, such as GMM, SM, SMS message or RRC layer signaling message. The GTP tunnel of the user plane is established, maintained or released between the Node B + WA1 and the GGSN through a Gn interface control plane GTP protocol, and the GTP tunnel protocol, UDP and IP between the Node B + WA1 and the GGSN are directly carried on the DSL network. The Gn interface protocol stack processing comprises GTP control plane (GTP-C), UDP, IP, LNK and PHY layer processing.

Referring to fig. 4c, a WA1 is provided in a base station BS for wireless access, control and management, the BS is interconnected with a reference point T in a DSL network through a WA1, and data in a wireless communication network is accessed to a wired network through a Modem; a WA2 is provided, the WA2 is interconnected with a BRAS through a reference point a10, and data in the DSL network is accessed to a core network, so that interconnection of a wired network and a wireless network is realized. In this interconnection mode, the network elements BS, WA1 and DSLModem may be logically separated or integrated, and the network elements BRAS and WA2 may also be logically separated or integrated.

For fig. 4c, there are three implementation modes, which are:

mode (6): WA1 corresponds to the function of an RNC and WA2 corresponds to the function of an SGSN, namely WA1 is RNC and WA2 is SGSN;

mode (7): WA1 corresponds to the function of RNC and WA2 corresponds to the functions of SGSN and GGSN, namely WA1 is RNC and WA2 is SGSN + GGSN;

mode (8): WA1 corresponds to RNC and SGSN functions, WA2 corresponds to GGSN functions, WA1 is RNC + SGSN and WA2 is GGSN.

The above three modes are described separately from the protocol stack perspective below.

Reference is made to fig. 19 and 20, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (6) in the embodiment shown in fig. 4 c. In this example, Node B is provided with WA1, where Node B provided with WA1 is referred to as Node B + WA 1; the BRAS and WA2 are combined into one logical entity and is referred to as BRAS + WA 2.

For uplink user plane data: the application layer data of the UE is encapsulated into a data packet and sent to the RNL, where the data packet may be a user IP data packet or a PPP protocol packet. The RNL compresses the packet header, adds a header specified by a protocol, such as an RLC/MAC header, and then sends the header to the RFL of the physical layer, and the RFL performs operations such as coding modulation on the received packet and then sends the packet to the UTRAN through a Uu interface. Because WA1 is equivalent to the function of RNC and WA2 is equivalent to the function of SGSN, RFL of Node B + WA1 in UTRAN, after receiving the data packet, sequentially removes the protocol header, and after re-combination and header compression processing, forwards the data packet to BRAS + WA2 through the Iu interface via GTP tunnel, and Iu interface GTP tunnel protocol, UDP and IP between WA1 and WA2 are directly carried on DSL network, specifically, two-layer bridging technology or three-layer routing technology can be used between WA1 and WA2 to implement transmission. For the protocol stack shown in fig. 19, the specific implementation process is as follows:

node B + WA1 divides GTP/UDP/IP frame into Ethernet ETH frame, and sends it to DSL Modem through cable in Ethernet physical layer PHY; the Ethernet PHY of the DSL Modem converts the received data into an ETH frame, then carries out DOCSIS modulation processing to convert the ETH frame into a DSL physical frame suitable for twisted pair transmission in a cable network, and transmits the DSL physical frame to the DSLAM through a twisted pair; carrying out DOCSIS demodulation processing on a DSL physical frame of the DSLAM to obtain an ETH frame, and then sending an Ethernet physical layer PHY (physical layer) carried between the DSLAM and the BRAS of the ETH frame to the BRAS + WA2 for further processing;

and the BRAS + WA2 Ethernet PHY processes to obtain an ETH frame, the ETH frame is subjected to Ethernet MAC processing to obtain an IP packet, the IP packet is subjected to IP routing to obtain a UDP packet, and then the BRAS + WA2 receives data from a GTP tunnel of the Iu interface and sends the data to the CN through the Gn interface by the GTP tunnel.

At CN, the data received by GGSN from GTP tunnel of Gn interface is user IP data packet or PPP protocol packet of UE, and GGSN sends the user IP data packet or PPP protocol packet to external network through Gi interface. For DSL data service, BRAS + WA2 only performs IP/LNK/PHY processing on data.

For uplink control plane data: the UE side encapsulates signaling messages, such as GMM, SM, SMS messages or signaling messages of an RRC layer, into data packets in an RNL, adds headers specified by a protocol, such as RLC/MAC headers, by an RLC, and then sends the data packets to an RFL of a physical layer, and the RFL performs operations of coding modulation and the like on the received data packets and then sends the data packets to the UTRAN through a Uu interface. After receiving the data packet, the RFL of Node B + WA1 in UTRAN removes the protocol header from the data packet in turn, recombines and combines them, sends the data to the RRC protocol of RNL, analyzes the signaling message, and performs corresponding processing, such as connection establishment, measurement report, etc. But for GMM/SM/SMs messages, Node B + WA1 will directly hand over the corresponding message to BRAS + WA2 process through the radio network layer (e.g., NANAP) and transport network layer of Iu interface. The transmission network layer of the Iu interface comprises SCCP/M3UA/SCTP/IP/LNK/PHY, wherein M3UA/SCTP/IP is Signaling Bearer in the figure. The radio network layer (e.g., NANAP) and the transport network layer (e.g., SCCP/M3UA/SCTP/IP) of the Iu interface between WA1 and WA2 are directly carried over the DSL network, and specifically, a two-layer bridging technique or a three-layer routing technique may be adopted between WA1 and WA2 to implement transmission. For the protocol stack shown in fig. 20, the specific implementation process is as follows:

node B + WA1 divides RANAP/SCCP/M3UA/SCTP/IP frame into Ethernet ETH frame, and Ethernet physical layer PHY carried between Node B + WA1 and DSL Modem is sent to DSL Modem; the DSLModem PHY processes to obtain an ETH frame, then performs DOCSIS modulation processing to convert the ETH frame into a DSL physical frame suitable for twisted pair transmission, and transmits the DSL physical frame to the DSLAM through a twisted pair; the DSLAM DSL physical frame is processed by DOCSIS demodulation to obtain ETH frame, and the Ethernet physical layer PHY of the ETH frame carried between the DSLAM and the BRAS is sent to the BRAS + WA2 for further processing.

BRAS + WA2 Ethernet PHY processing obtains ETH frame, to ETH frame do Ethernet MAC processing obtains IP packet, obtain UDP packet after IP route, then BRAS + WA2 do Iu interface transport network layer and wireless network layer processing, obtain GMM/SM/SMS message from RANAP. For DSL data service, BRAS only carries out IP/LNK/PHY processing on data.

Reference is made to fig. 21 and fig. 22, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (7) in the embodiment shown in fig. 4 c. The differences from the protocol stacks shown in fig. 19 and 20 are: WA2 corresponds to the function of an SGSN and GGSN. Thus, no further processing of the SGSN and GGSN is required for the CN. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 19 and 20 will be described below, and the same parts will not be described again.

For uplink user plane data, when BRAS + WA2 Ethernet PHY processing obtains ETH frame, the ETH frame is processed by Ethernet MAC to obtain IP packet, after IP routing, UDP packet is obtained, then BRAS + WA2 receives data packet from GTP tunnel of Iu interface, transmission network layer and wireless network layer processing of Iu interface are carried out to obtain user IP data packet or PPP protocol packet of UE, and the user IP data packet or PPP protocol packet is sent to external network through network element in CN. The processing of the transmission network layer of the Iu interface comprises the processing of GTP, UDP, IP, LNK and PHY layers, and the wireless network layer of the Iu interface is the processing of Iu UP protocol and is used for transmitting the user data related to RAB.

For uplink control plane data, after the BRAS + WA2 ethernet PHY processes to obtain an ETH frame, LNK decapsulation is performed on the received data to obtain signaling bearer layer data, the data is converted into an SCCP frame, since the Iu interface frame protocol SCCP between WA1 and WA2 is directly carried on the DSL network, at this time, it can be regarded as WA2 directly obtaining an SCCP frame from the Iu interface, decapsulating the SCCP to obtain a data packet in the RNL, such as RANAP, and then WA2 performs RANAP protocol processing on the data packet to obtain a signaling message at the UE side, such as GMM, SM, SMs message. The processing of the transport network layer of the Iu interface comprises the processing of SCCP, Signaling Bearer, LNK and PHY layers, and the processing of the radio network layer of the Iu interface comprises the processing of RANAP.

Reference is made to fig. 23 and 24, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (8) in the implementation shown in fig. 4 c. The differences from the protocol stacks shown in fig. 21 and 22 are: WA1 corresponds to RNC and SGSN, WA2 corresponds to GGSN functionality. Thus, no further processing of the SGSN and GGSN is required for the CN. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 21 and 22 will be described below, and the same parts will not be described again.

For uplink user plane data: after UE sends data to UTRAN through Uu interface, WA1 is equivalent to RNC and SGSN functions, therefore, after RFL of Node B + WA1 in UTRAN receives data packet, protocol header is removed in turn, and after recombination and header decompression processing, the data packet is forwarded to WA2 through GTP tunnel through Gn interface, and GTP tunnel protocol, UDP and IP between WA1 and WA2 are directly carried on DSL network.

WA2 processes Gn interface protocol stack, the data received from GTP tunnel is user IP data packet or PPP protocol packet of UE, WA2 sends to CN in form of user IP data packet or PPP protocol packet.

For uplink control plane data, after the UE side sends signaling message to UTRAN through Uu interface, because WA1 is equivalent to the functions of RNC and SGSN, RFL of Node B + WA1 in UTRAN receives the data packet, removes protocol headers from the data packet in sequence, recombines and merges the data, sends the data to RNL, and after RNL layer processing, WA2 obtains signaling message of UE side, such as GMM, SM, SMs message or signaling message of RRC layer. User plane GTP tunnel is established, maintained or released between NodeB + WA1 and WA2 through Gn interface control plane GTP protocol, and GTP tunnel protocol, UDP and IP between NodeB + WA1 and BRAS + WA2 are directly carried on DSL network. The Gn interface protocol stack processing comprises GTP control plane (GTP-C), UDP, IP, LNK and PHY layer processing.

In the embodiments shown in fig. 19 to 24, BRAS and WA2 may be independent of each other, i.e., may be separate logical entities.

And a second interconnection scheme:

as shown in fig. 25a, 25b and 25c, three embodiments of the present invention are applied, and the three embodiments are characterized in that: the BS or WA1 in the wireless communication network is interconnected with the reference point V of the DSL network in the DSL network, and the WA2 or CN in the wireless communication network is interconnected with the BRAS in the reference point A10, thereby realizing the interconnection of the wireless communication network and the DSL network. The scheme belongs to a loose coupling scheme, and can support unified charging, unified Customer service (Customer Care) and unified authentication. The three embodiments described above differ in that only WA2 is present in the embodiment shown in fig. 25a, only WA1 is present in the embodiment shown in fig. 25b, and both WA1 and WA2 are present in the embodiment shown in fig. 25 c.

Referring to fig. 25a, 25b, and 25c, when data is communicated, the UE first establishes an RRC connection through a control plane protocol stack, and starts RAB establishment after negotiation with a core network, where the RAB establishment process is accompanied by user plane RB establishment. After the RAB establishment is successful, the user can transmit data through the established user plane bearer. The compression and decompression functions of the PDCP may or may not be enabled. The signaling establishment process is that after the RRC connection between the UE and the UTRAN is successfully established, the UE establishes a signaling connection with the CN through the RNC, which is also called "NAS signaling establishment process" and is used for signaling interaction NAS information between the UE and the CN, such as authentication, service request, connection establishment, and the like. The following describes the transmission process of user plane and control plane data by taking the compression and decompression functions as an example. Wherein, the RNL of the Uu interface includes PDCP, RLC and MAC in the user plane, and RRC, RLC and MAC in the control plane.

Referring to fig. 25a, a base station BS for wireless access, control and management is interconnected with a reference point V in a DSL network, and data in a wireless communication network is accessed to a wired network through a BRAS via a convergence network in the DSL network; a WA2 is provided, the WA2 is interconnected with a BRAS through a reference point a10, and data in the DSL network is accessed to a core network, so that interconnection of a wired network and a wireless network is realized. In this interconnection scheme, network elements BRAS and WA2 may also be logically separated or integrated.

For fig. 25a, there are three further implementation modes, respectively:

mode (1): WA2 corresponds to the function of an RNC, namely WA2 ═ RNC;

Reference is made to fig. 26 and fig. 27, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (1) in the embodiment shown in fig. 25 a. In this example, the SGSN and GGSN in the CN are combined into a new network element, and this network element is referred to as IGSN. Based on the protocol stack structure:

for uplink user plane data: the application layer data of the UE is encapsulated into a data packet and sent to the RNL, where the data packet may be a user IP data packet or a PPP protocol packet. The RNL compresses the packet header, adds a header specified by a protocol, such as an RLC/MAC header, and then sends the header to the RFL of the physical layer, and the RFL performs operations such as coding modulation on the received packet and then sends the packet to the UTRAN through a Uu interface. After receiving the data packet, the RFL of the Node B in UTRAN encapsulates the data packet into a frame protocol FP frame, adds an IP header to the FP frame, i.e., after IP processing, sends the processed IP packet, i.e., the FP/IP frame, to the WA2 through the Iub interface. And the Iub interface frame protocol FP/IP frame between Node B and WA2 is carried directly on the convergence network in DSL network. For the protocol stack shown in fig. 26, the specific implementation process is as follows:

node B divides FP/IP frame into ETH frame, and sends it to BRAS through convergence network in DSL network at Ethernet physical layer PHY; the BRAS ethernet PHY converts the received data into an ETH frame again, performs ethernet MAC processing on the ETH frame to obtain an IP packet, performs LNK encapsulation on the IP packet again, and then the BRAS sends the physical layer PHY, which carries the encapsulated data between the BRAS and the WA2, to the WA2 for further processing.

At this time, the WA2 corresponds to the function of the RNC, and thus is exactly the same as the processing of the conventional RNC user plane, specifically: WA2 receives data through PHY, gets FP/IP frame after LNK decapsulation to the received data, converts the FP/IP frame into FP frame, because Iub interface frame protocol FP/IP frame between Node B and WA2 is directly loaded on DSL network, at this moment, it can be regarded as WA2 gets FP/IP frame directly from Iub interface, gets data packet in RNL after decapsulation of the FP/IP frame, then WA2 sends the data packet to network element in CN through GTP tunnel after making Iu interface transmission network layer and wireless network layer process. The processing of the transmission network layer of the Iu interface includes processing of a GTP user plane (GTP-U), UDP, IP, LNK, and PHY layers, and the wireless network layer of the Iu interface is Iu UP protocol processing for transmitting user data related to RAB. .

For uplink control plane data: the UE side encapsulates the signaling message, such as GMM, SM, SMS message or signaling message of RRC layer, into data packet in RNL, adds the header specified by protocol, such as RLC/MAC header, by RNL, sends the data packet to RFL of physical layer, and the RFL performs operations such as coding modulation to the received data packet and sends the data packet to UTRAN through Uu interface. After receiving the data packet, the RFL of the Node B in UTRAN encapsulates the data packet into an Iub interface radio network layer frame, for example, an FP frame, and transmits the network layer, for example, IP/ETH/PHY, through the Iub interface to carry the data packet to WA 2. The radio network layer (such as FP or NBAP) of the Iub interface between Node B and WA2 and the IP layer or signaling bearer layer of the transport network layer are carried directly on top of the aggregation network in the DSL network. For the protocol stack shown in fig. 27, the specific implementation process is as follows:

node B divides FP/IP frame or NBAP/SCTP/IP frame into ETH frame, and sends it to BRAS through convergence network in DSL network at Ethernet physical layer PHY. The BRAS ethernet PHY converts the received data into an ETH frame again, performs ethernet MAC processing on the ETH frame to obtain an IP packet, performs LNK encapsulation on the IP packet again, and then the BRAS sends the physical layer PHY, which carries the encapsulated data between the BRAS and the WA2, to the WA2 for further processing.

At this time, the WA2 is equivalent to the function of the RNC, so it is exactly the same as the processing of the conventional RNC control plane, specifically: WA2 receives data through PHY, de-encapsulates the received data with LNK to get FP/IP frame or signaling carrying layer data, removes IP head to get FP frame for FP/IP frame, SCTP and IP process for signaling carrying data to get NBAP frame, because Iub interface frame protocol FP/IP frame or NBAP frame between Node B and WA2 is carried on convergence network in DSL network directly, at this time, it can be regarded as WA2 to get FP/IP frame or NBAP frame from Iub interface directly. If WA2 receives the NBAP frame, processing the NBAP frame accordingly; if WA2 receives the FP/IP frame, it removes the IP header from the FP/IP frame to obtain the FP frame, and de-encapsulates the FP frame to obtain the data packet in RNL, and then WA2 processes the data packet by the transport network layer and the radio network layer of Iu interface and sends it to the network element in CN. The processing of the transport network layer of the Iu interface comprises the processing of SCCP, SignalingBearer, LNK and PHY layers, and the processing of the radio network layer of the Iu interface comprises the processing of RANAP.

Reference is made to fig. 28 and fig. 29, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (2) in the embodiment shown in fig. 25 a. The differences from the protocol stacks shown in fig. 26 and 27 are: WA2 corresponds to the functions of an RNC and SGSN. Thus, for CN, only GGSN process is needed, and SGSN process is no longer needed. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 26 and 27 will be described below, and the same parts will not be described again.

For uplink user plane data: WA2 receives data through PHY, gets FP/IP frame after LNK decapsulation to the received data, converts the FP/IP frame into FP frame, because Iub interface frame protocol FP/IP frame between Node B and WA2 is directly loaded on convergence network in DSL network, at this time, it can be regarded as WA2 directly getting FP/IP frame from Iub interface, get data packet in RNL after decapsulating the FP/IP frame, then WA2 sends the data packet to network element in CN through GTP tunnel after Gn interface protocol stack processing. And the Gn interface protocol stack processing comprises the processing of a GTP user plane (GTP-U), UDP, IP, LNK and PHY layers.

For uplink control plane data: WA2 receives data through PHY, de-encapsulates the received data with LNK to get FP/IP frame or signaling carrying layer data, removes IP head to get FP frame for FP/IP frame, SCTP and IP process for signaling carrying data to get NBAP frame, because Iub interface frame protocol FP/IP frame or NBAP frame between Node B and WA2 is carried on convergence network in DSL network directly, at this time, it can be regarded as WA2 to get FP/IP frame or NBAP frame from Iub interface directly. If WA2 receives the NBAP frame, processing the NBAP frame accordingly; if WA2 receives the FP/IP frame, decapsulate the FP/IP frame to obtain a data packet in RNL, after RNL layer processing, WA2 obtains a signaling message of UE side, such as GMM, SM, SMs message or a signaling message of RRC layer, and performs corresponding processing, such as establishing connection, measurement report, etc., i.e. WA2 completes the control plane function of RNC, SGSN and GGSN. The user plane GTP tunnel is established, maintained or released between WA2 and GGSN via the Gn interface control plane GTP protocol. The Gn interface protocol stack processing comprises GTP control plane (GTP-C), UDP, IP, LNK and PHY layer processing.

Reference is made to fig. 30 and fig. 31, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (3) in the embodiment shown in fig. 25 a. The differences from the protocol stacks shown in fig. 26 and 27 are: WA2 corresponds to the functions of an RNC, SGSN and GGSN. Thus, the CN does not need to perform processing of the SGSN and GGSN, and other processing is as usual. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 26 and 27 will be described below, and the same parts will not be described again.

For uplink user plane data: WA2 decapsulates the received data with LNK to obtain FP/IP frame, converts the FP/IP frame into FP frame, because the FP frame is directly carried on the convergence network in DSL network by Iub interface frame protocol between Node B and WA2, at this time, WA2 can be regarded as directly obtaining FP/IP frame from Iub interface, decapsulate the FP/IP frame to obtain data packet in RNL, then WA2 routes the data packet to external network through CN.

For uplink control plane data: WA2 receives data through PHY, de-encapsulates the received data with LNK to get FP/IP frame or signaling carrying layer data, removes IP head to get FP frame for FP/IP frame, SCTP and IP process for signaling carrying data to get NBAP frame, because Iub interface frame protocol FP/IP frame or NBAP frame between Node B and WA2 is carried on convergence network in DSL network directly, at this time, it can be regarded as WA2 to get FP/IP frame or NBAP frame from Iub interface directly. If WA2 receives the NBAP frame, processing the NBAP frame accordingly; if WA2 receives the FP/IP frame, decapsulate the FP/IP frame to obtain a data packet in RNL, after RNL layer processing, WA2 obtains a signaling message of UE side, such as GMM, SM, SMs message or a signaling message of RRC layer, and performs corresponding processing, such as establishing connection, measurement report, etc., i.e. WA2 completes the control plane function of RNC, SGSN and GGSN.

Referring to fig. 25b, a WA1 is provided in a base station BS for wireless access and control, management, the BS is interconnected with a reference point N in a DSL network through a WA1, and data in a wireless communication network is accessed to a wired network through a BRAS via a convergence network in the DSL network; the BRAS in the wired network accesses the data in the DSL network to the core network through the reference point a10, so as to realize interconnection between the wired network and the wireless network. In this interconnection, the network elements BS, WA1 may be logically separated or integrated.

For fig. 25b, there are two more modes of implementation, respectively:

mode (4): WA1 corresponds to the function of an RNC, namely WA1 ═ RNC;

Reference is made to fig. 32 and fig. 33, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (4) in the embodiment shown in fig. 25 b. In this example, Node B is provided with WA1, and Node B provided with WA1 is referred to as Node B + WA 1.

For uplink user plane data: the application layer data of the UE is encapsulated into a data packet and sent to the RNL, where the data packet may be a user IP data packet or a PPP protocol packet. The RNL compresses the packet header, adds a header specified by a protocol, such as an RLC/MAC header, and then sends the header to the RFL of the physical layer, and the RFL performs operations such as coding modulation on the received packet and then sends the packet to the UTRAN through a Uu interface. Because WA1 is equivalent to the function of RNC, RFL of Node B + WA1 in UTRAN, after receiving the data packet, sequentially removes the protocol header, and after re-combination and header decompression processing, forwards the data packet to CN through Iu interface via GTP tunnel, and GTP tunnel protocol, UDP and IP between WA1 in Node B and CN are directly carried on the convergence network in DSL network. For the protocol stack shown in fig. 32, the specific implementation process is as follows:

node B + WA1 divides GTP/UDP/IP packet into Ethernet ETH frame, and sends it to BRAS through convergence network in DSL network at Ethernet physical layer PHY; the BRAS converts the received data into an ETH frame again, performs Ethernet MAC processing on the ETH frame to obtain an IP packet, performs LNK encapsulation on the IP packet again, and then loads the encapsulated data on a physical layer PHY between the BRAS and the CN to be sent to the CN for further processing.

For uplink control plane data: the UE side encapsulates the signaling message, such as GMM, SM, SMS message or signaling message of RRC layer, into data packet in RNL, adds the header specified by protocol, such as RLC/MAC header, by RNL, sends the RFL to physical layer, and sends the received data packet to UTRAN through Uu interface after coding modulation. After receiving the data packet, the RFL of Node B + WA1 in UTRAN removes the protocol header from the data packet in turn, recombines and combines them, sends the data to the RRC protocol of RNL, analyzes the signaling message, and performs corresponding processing, such as connection establishment, measurement report, etc. But for GMM/SM/SMs messages, Node B + WA1 will directly hand the corresponding message over the radio network layer (e.g., NANAP) and transport network layer of the Iu interface to the CN process. The transmission network layer comprises SCCP/M3UA/SCTP/IP/LNK/PHY, wherein M3UA/SCTP/IP is Signaling Bearer in the figure. The radio network layer (e.g., NANANANAP) and transport network layer (e.g., SCCP/M3UA/SCTP/IP) of the Iu interface between WA1 in the NodeB and the CN are carried directly on top of the aggregation network in the DSL network. For the protocol stack shown in fig. 33, the specific implementation process is as follows:

node B + WA1 divides RANAP/SCCP/M3UA/SCTP/IP packet into Ethernet ETH frame, and sends it to BRAS through convergence network in DSL network at Ethernet physical layer PHY; the BRAS converts the received data into an ETH frame again, performs Ethernet MAC processing on the ETH frame to obtain an IP packet, performs LNK encapsulation on the IP packet again, and then loads the encapsulated data on a physical layer PHY between the BRAS and the CN to be sent to the CN for further processing.

Reference is made to fig. 34 and fig. 35, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (5) in the embodiment shown in fig. 25 b. The differences from the protocol stacks shown in fig. 32 and 33 are: WA1 corresponds to the functions of an RNC and SGSN. Thus, for CN, only GGSN process is needed, and SGSN process is no longer needed. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 32 and 33 will be described below, and the same parts will not be described again.

For uplink user plane data: after UE sends data to UTRAN through Uu interface, WA1 is equivalent to RNC and SGSN function, therefore, after RFL of Node B + WA1 in UTRAN receives data packet, it removes protocol header 0 in turn, after recombination and header compression, it transmits data packet to CN through GTP tunnel through Gn interface, and GTP tunnel protocol, UDP and IP between WA1 and CN are carried on convergence network in DSL network directly.

For uplink control plane data: after the UE side sends the signaling message to UTRAN through Uu interface, because WA1 is equivalent to RNC and SGSN function, RFL of Node B + WA1 in UTRAN receives the data packet and removes the protocol header in turn, through recombination and combination, sends the data to RNL, after RNL layer processing, obtains the signaling message of UE side, such as GMM, SM, SMS message or RRC layer signaling message. The GTP tunnel of the user plane is established, maintained or released between the Node B + WA1 and the GGSN through a Gn interface control plane GTP protocol, and the GTP tunnel protocol, UDP and IP between the Node B + WA1 and the GGSN are directly carried on a convergence network in the DSL network. The Gn interface protocol stack processing comprises GTP control plane (GTP-C), UDP, IP, LNK and PHY layer processing.

For fig. 25c, there are three additional modes of implementation, respectively:

Reference is made to fig. 36 and 37, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (6) in the embodiment shown in fig. 25 c. In this example, Node B is provided with WA1, where Node B provided with WA1 is referred to as Node B + WA 1; the BRAS and WA2 are combined into one logical entity and is referred to as BRAS + WA 2.

For uplink user plane data: the application layer data of the UE is encapsulated into a data packet and sent to the RNL, where the data packet may be a user IP data packet or a PPP protocol packet. The RNL compresses the packet header, adds a header specified by a protocol, such as an RLC/MAC header, and then sends the header to the RFL of the physical layer, and the RFL performs operations such as coding modulation on the received packet and then sends the packet to the UTRAN through a Uu interface. Since WA1 corresponds to the function of RNC and WA2 corresponds to the function of SGSN, RFL of Node B + WA1 in UTRAN, after receiving the packet, sequentially removes the protocol header, and after re-combination and header compression, forwards the packet to BRAS + WA2 through the Iu interface via GTP tunnel.

Node B + WA1 divides GTP/UDP/IP frame into Ethernet ETH frame to be sent to BRAS + WA2 for further processing;

For uplink control plane data: the UE side encapsulates the signaling message, such as GMM, SM, SMS message or signaling message of RRC layer, into data packet in RNL, adds the header specified by protocol, such as RLC/MAC header, by RNL, sends the data packet to RFL of physical layer, and the RFL performs operations such as coding modulation to the received data packet and sends the data packet to UTRAN through Uu interface. After receiving the data packet, the RFL of Node B + WA1 in UTRAN removes the protocol header from the data packet in turn, recombines and combines them, sends the data to the RRC protocol of RNL, analyzes the signaling message, and performs corresponding processing, such as connection establishment, measurement report, etc. But for GMM/SM/SMs messages, Node B + WA1 will directly hand over the corresponding message to BRAS + WA2 process through the radio network layer (e.g., NANAP) and transport network layer of Iu interface. The transmission network layer comprises SCCP/M3UA/SCTP/IP/LNK/PHY, wherein M3UA/SCTP/IP is SignalingBearer in the figure.

Node B + WA1 divides RANAP/SCCP/M3UA/SCTP/IP frame into Ethernet ETH frame, loads the ETH frame on Ethernet physical layer PHY and sends it to BRAS + WA2 for further processing.

BRAS + WA2 Ethernet PHY processing obtains ETH frame, to ETH frame do Ethernet MAC processing obtains IP packet, obtain UDP packet after IP route, then BRAS + WA2 do Iu interface transport network layer and wireless network layer processing, obtain GMM/SM/SMS message from RANAP. For DSL data service, BRAS + WA2 only performs IP/LNK/PHY processing on data.

Reference is made to fig. 38 and 39, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (7) in the embodiment shown in fig. 25 c. The differences from the protocol stacks shown in fig. 36 and 37 are: WA2 corresponds to the function of an SGSN and GGSN. Thus, no further processing of the SGSN and GGSN is required for the CN. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 36 and 37 will be described below, and the same parts will not be described again.

For uplink control plane data, after the BRAS + WA2 ethernet PHY processes to obtain an ETH frame, LNK decapsulation is performed on the received data to obtain signaling bearer layer data, the data is converted into an SCCP frame, since the Iu interface frame protocol SCCP between WA1 and WA2 is directly carried on the DSL network, at this time, it can be regarded as WA2 directly obtaining an SCCP frame from the Iu interface, decapsulating the SCCP frame to obtain a data packet in the RNL, such as RANAP, and then WA2 performs RANAP protocol processing on the data packet to obtain a signaling message at the UE side, such as GMM, SM, SMs message. The processing of the transport network layer of the Iu interface comprises the processing of SCCP, Signaling Bearer, LNK and PHY layers, and the processing of the radio network layer of the Iu interface comprises the processing of RANAP.

Reference is made to fig. 40 and 41, which are schematic diagrams of protocol stack structures of a user plane and a control plane, respectively, for an embodiment of mode (8) in the embodiment shown in fig. 25 c. The differences from the protocol stacks shown in fig. 38 and 39 are: WA1 corresponds to RNC and SGSN, WA2 corresponds to GGSN functionality. Thus, no further processing of the SGSN and GGSN is required for the CN. Since the protocol stack structure is changed, the processing steps are also changed accordingly, and only differences from the processing in fig. 38 and 39 will be described below, and the same parts will not be described again.

For uplink user plane data: after UE sends data to UTRAN through Uu interface, WA1 is equivalent to RNC and SGSN function, therefore, after RFL of Node B + WA1 in UTRAN receives data packet, removes protocol header in turn, after recombination and header decompression process, forwards data packet to BRAS + WA2 through GTP tunnel through Gn interface, and GTP tunnel protocol, UDP and IP between WA1 and WA2 are carried on convergence network in DSL network directly.

And the BRAS + WA2 performs Gn interface protocol stack processing, the data received from the GTP tunnel is the user IP data packet or PPP protocol packet of the UE, and the BRAS + WA2 is sent to the CN in the form of the user IP data packet or PPP protocol packet.

For uplink control plane data, after the UE side sends a signaling message to the UTRAN through the Uu interface, since WA1 is equivalent to the functions of the RNC and SGSN, RFL of Node B + WA1 in UTRAN receives the data packet, then removes the protocol headers from the data packet in sequence, recombines and merges the data, sends the data to RNL, and after RNL layer processing, BRAS + WA2 obtains the signaling message of the UE side, such as GMM, SM, SMs message or signaling message of RRC layer. And the Node B + WA1 and the BRAS + WA2 establish, maintain or release a user plane GTP tunnel through a Gn interface control plane GTP protocol. The Gn interface protocol stack processing comprises GTP control plane (GTP-C), UDP, IP, LNK and PHY layer processing.

In the embodiments shown in fig. 36 to 41, BRAS and WA2 may be independent of each other, i.e., may be separate logical entities. In the embodiments shown in fig. 32 to 41, Node B and WA1 may be independent of each other, i.e. they may be an independent logical entity.

In the above, the WCDMA is taken as an example, and for other networks, such as GSM, WiMAX, etc., the processing method is the same as that of WCDMA, and only the name of the logical entity performing the operation changes accordingly. Therefore, it can be seen that the present invention is actually to provide a first logic unit and a second logic unit in a wireless communication network; the first logic unit and the DSL modem in the DSL network jointly form a first processing unit, and the second logic unit and the BRAS in the DSL network jointly form a second processing unit; and the wireless communication network data transmitted between the first processing unit and the second processing unit is carried by the DSL network, or the wireless communication network data transmitted between the first logic unit and the second processing unit is carried by the DSL network.
