Description

Identification information distribution, acquisition method and device

technical field

The embodiments of the present invention relate to the field of mobile communications, and in particular, to a method and device for distributing and acquiring identification information.

Background technique

The Universal Mobile Telecommunication System (hereinafter referred to as: UMTS) system is the third-generation mobile communication system, which adopts a structure similar to that of the second-generation mobile communication system, as shown in Figure 1, which is the existing technology of UMTS. Architecture diagram, including radio access network (Radio Access Network, hereinafter referred to as: RAN) and core network (Core Network, hereinafter referred to as: CN), RAN in UMTS is also called Universal Terrestrial Radio Access Network (Universal Terrestrial Radio Access Network) , hereinafter referred to as: UTRAN). Among them, RAN is used to handle functions related to wireless, while CN is used to handle all voice calls and data connection functions within UMTS, and realize switching and routing functions with external networks. CN is logically divided into a circuit switched domain (Circuit Switched domain, hereinafter referred to as: CS) and a packet switched domain (Packet Switched domain, hereinafter referred to as: PS). UTRAN, CN and user equipment (User Equipment, hereinafter referred to as: UE) constitute the entire UMTS.

As shown in Figure 2, it is a schematic structural diagram of the prior art UMTS. The system structure can be further refined. In UTRAN, NodeB is a base station, including wireless transceivers and baseband processing components. NodeB communicates with wireless networks through standard Iub interfaces. The controllers (Radio Network Controller, hereinafter referred to as: RNC) are interconnected, and the RNC is used to complete functions such as connection establishment and disconnection, handover, macro-diversity combination, and radio resource management control. CN is responsible for connection with other networks and communication and management for UE. Among them, MSC/VLR is the WCDMA core network CS domain functional node, connected to UTRAN through the Iu_CS interface, providing functions such as call control, mobility management, authentication and encryption in the CS domain; SGSN is the WCDMA core network PS domain functional node, through The Iu_PS interface is connected to the UTRAN and provides functions such as route forwarding, mobility management, session management, authentication, and encryption in the PS domain. As shown in Figure 3, it is a schematic diagram of the interconnection between UTRAN and CN in the prior art. The interfaces between UTRAN and CN are collectively referred to as Iu interfaces, including Iu_CS interfaces and Iu_PS interfaces. The interfaces between RNCs are Iur interfaces, and between RNCs and NodeBs The interface between is the Iub interface.

Facing the hotspot coverage competition pressure of Wi-Fi and WiMAX, operators are seeking 2G, 3G, LTE partial coverage solutions to meet the needs of families and small businesses, such as home base stations (HomeNodeB, hereinafter referred to as: HNB), or It is called the femtocell base station and has become the most potential low-cost access technology at present. As shown in Figure 4, it is a schematic diagram of the position in the mobile communication network of HNB. HNB can process cellular mobile phone calls locally, and then transmit them to the operator's core network through broadband such as DSL or cable modem, which not only reduces the number of calls to many It also reduces the investment in expanding network coverage and capacity. As a home base station, HNB has the following characteristics compared with traditional macro base stations: small coverage; limited number of users; large number; dense deployment; multi-layer overlapping coverage of equipment managed by HNB users, rather than operator-controlled equipment ; HNB frequency band: It may be deployed in a different frequency from the Legacy network; the transmission power is small; it is difficult to configure the HNB neighbor list.

At present, various communication manufacturers are actively discussing the implementation scheme of HNB in UMTS and its various evolution versions (HSPA+ or LTE). As shown in Figure 5, it is a schematic diagram of the architecture of a 3G HNB in the prior art. The UE is connected to the HNB through a standard UU interface, and the HNB is connected to the core network through the HNB Gateway (HNB GW), and an interface based on the Iu interface extension can be used. eIu, HNB GW connects to the core network through the standard Iu interface, connects to the CS through the Iu-CS, and connects to the PS through the Iu-PS. In the current standard, whether there is an Iur connection between the HNB and the RNC of the macro network, and how to establish the Iur connection have not been discussed yet. As shown in Figure 6, it is a schematic diagram of the architecture of the prior art LTE HNB. The UE is connected to the HNB through the standard LTE air interface, and the HNB can directly or indirectly (through the HNB GW) access the core network EPC through the S1 interface.

In the above technical scenario, the URNTI is the unique identifier of the UE on the RAN side. URNTI is 32bit and consists of two parts, namely SRNCID and SRNTI. SRNCID is the identifier of RNC, and SRNTI is the identifier assigned to UE by SRNC. SRNCID can be 12bit, SRNTI is 20bit, or SRNCID is 16bit, and SRNTI is 16bit. In UMTS, the allocation of URNTI is allocated by the SRNC entity of the UE's RRC connection termination point when the UE establishes the RRC connection, and is sent to the UE through the downlink message of establishing the RRC connection. As shown in FIG. 7, it is a signaling flowchart for allocating URNTI in the prior art, including:

Step 101, UE sends RRC connection request message to SRNC, triggers establishment of RRC connection:

Step 102, SRNC distributes URNTI, sends the RRC connection establishment message carrying URNTI to UE;

In step 103, the UE sends an RRC connection establishment complete message to the SRNC.

After research, the inventor found that if the prior art scheme in which the SRNC entity of the RRC connection termination point is responsible for allocating URNTI is applied to the HNB network, the following defects will exist: for the HNB network, the RRC connection of the UE will be terminated by the RNC on the HNB entity, so according to the prior art, the URNTI should be allocated by the HNB during the establishment of the RRC connection and sent to the UE.

If you want to ensure that the URNTI allocated by HNB is unique in UTRAN, you must first allocate a unique SRNCID in UTRAN for HNB, and the number of RNCIDs is limited, currently 12 or 16 bits, and the number of HNBs is huge, so RNCID resources will not be enough.

If it is not guaranteed that the URNTI allocated by the HNB is unique within UTRAN, then each HNB can be assigned a local SRNCID valid under the HNB GW. This SRNCID is only valid within the HNB GW and is not valid and unique within the UTRAN. HNB uses this The local SRNCID can allocate URNTI, but because this local SRNCID may be used by the RNC of the macro network, the URNTI may overlap with the URNTI allocated by the RNC of the macro network, which will cause the following problems: When the UE moves from the HNB to the external macro network And when a cell update message is initiated, the cell update message carries the URNTI of the UE. If the URNTI is valid and unique within the HNB GW, the RNC of the macro network does not know that the URNTI is a partial URNTI, and it will be processed as a normal URNTI, and the source RNC of the UE will be located within the range of UTRAN but outside the range of the HNB GW Other RNCs. And in the subsequent process, the relevant message will be routed to a certain RNC within the UTRAN range but outside the HNB GW range, resulting in an error. Similar problems also exist when UE moves from one HNB under the HNB GW to another HNB.

Detailed ways

The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

The identification information allocation method in the embodiment of the present invention includes: receiving an allocation trigger message corresponding to the identification information of the HNB gateway; allocating the identification information according to the allocation trigger message; and sending an allocation response message encapsulated with the identification information. The executor of the above steps may be HNB GW or other devices. The following takes HNB GW as an example to introduce the technical solution of the identification information distribution method in the embodiment of the present invention.

As shown in FIG. 8, it is a flowchart of a method for allocating identification information according to an embodiment of the present invention, which specifically includes the following steps:

Step 201, the HNB GW receives the allocation trigger message of the corresponding identification information of the HNB GW sent by the HNB;

Step 202, HNB GW allocates identification information according to the allocation trigger message;

Step 203, the HNB GW sends an allocation response message encapsulated with identification information to the HNB.

After the above step 203, it may also include:

Step 204, HNB GW receives the release request message of the identification information sent by HNB;

Step 205, the HNB GW releases the identification information, and returns a release response message of the identification information to the HNB.

The corresponding identification information of the above-mentioned HNB GW can be URNTI, and the HNB GW is responsible for allocating the URNTI, and sending the URNTI to the HNB, and the HNB forwards it to the UE; the above-mentioned identification information can also be SRNTI, and the HNB GW is responsible for allocating the SRNTI. SRNCID and SRNTI are synthesized to obtain URNTI, where SRNCID can be the pre-acquired RNC ID allocated by HNB GW; the above identification information can also be SRNCID, HNB GW is responsible for allocating SRNCID, and sending SRNCID to HNB, HNB is responsible for allocating SRNTI, and The received SRNCID is synthesized with the SRNTI allocated by itself to obtain the URNTI, which is forwarded to the UE.

In this embodiment, step 201 may be performed at the following timings: when the HNB starts, registers or configures, when the UE initiates RRC connection establishment, when the UE initiates a service, when the UE initiates handover or relocation. Wherein, step 201 is executed when the HNB starts, registers, or configures, that is, the allocation trigger message can be specifically a start message, a registration message, or a configuration message, so that it is not necessary to wait until the UE accesses before going to the HNB GW to request the allocation of URNTI; Step 201 is executed when the RRC connection is established, and URNTI is allocated or reconfigured for the UE established by RRC; Step 201 is executed when the UE initiates a service, and URNTI is allocated or reconfigured for the UE that has established an RRC connection; when the UE initiates a handover or Step 201 is executed during relocation, which implements reconfiguration of the URNTI during handover.

In this embodiment, the HNB obtains the assigned SRNCID, which is used to identify the HNB GW. Since the number of HNBGWs is much smaller than the number of HNBs, there will be no problem of insufficient RNCIDs; and, when the UE initiates a cell update process, according to The identification information will accurately determine the source RNC, so as to avoid errors.

The technical effects of the embodiments of the present invention are further described below by introducing the application scenarios of the identification information distribution and acquisition methods and devices of the embodiments of the present invention. For the embodiment of the present invention, in addition to the identifier SRNCID, the HNB GW also stores the identifier SRNTI of the UE and the correspondence between the SRNTI and the HNB.

An Iur interface is defined in advance from the HNB GW to the RNC of the macro cell. When the UE moves from a certain HNB to an outside macro cell, the UE sends a cell update message to the RNC of the macro cell. The cell update message includes URNTI; the macro cell The RNC of the macro cell queries the corresponding HNB GW according to the SRNC ID in the URNTI. According to the handover process, the RNC of the macro cell sends an uplink signaling transmission instruction message to the HNB GW. The uplink signaling transmission instruction message includes the URNTI; , query the corresponding UE and the corresponding HNB, and forward the uplink signaling transmission indication message to the HNB.

If there is no Iur interface between the HNB GW and the RNC of the macro cell, it is necessary for the CN to transfer forward handover messages such as the uplink signaling transmission indication message, where the CN refers to the SGSN or MSC node. Specifically, when the UE moves from a certain HNB to an outside macro cell, the UE sends a cell update message to the RNC of the macro cell, and the cell update message includes URNTI; the RNC of the macro cell sends an uplink signaling transmission indication message to the CN , the uplink signaling transmission indication message includes URNTI; CN queries the corresponding HNB GW according to the SRNCID in the URNTI, and forwards the uplink signaling transmission indication message to the HNB GW; the HNB GW queries the corresponding UE and the corresponding UE according to the SRNTI in the URNTI. HNB, and forward the uplink signaling transmission indication message to the HNB.

From the two application scenarios described above, when a UE moves from a HNB to an outside macro cell, the source RNC of the UE (here HNB GW) can be accurately found through the identification information allocated by the HNB GW, and then In the subsequent process, relevant messages can be accurately routed to the source RNC to avoid errors.

Similarly, when the UE moves from a certain HNB to an external macro network or to another HNB and initiates the relocation process, it can also accurately find the target RNC in the relocation needs message according to the identification information allocated by the HNB GW, and then Perform accurate routing in the follow-up process to avoid errors.
