technical field

Background technique

In the 4G Evolved Packet Core (EPC) network architecture defined in the existing 3rd Generation Partnership Project (3GPP) protocol, the Mobility Management Entity (MME) ) is the control plane function, the public data gateway (PDN Gateway, referred to as PGW)/Serving Gateway, referred to as the Serving Gateway, referred to as SGW) is the bearer plane function, the Serving GPRS Support Node (Servicing GPRS Support Node, referred to as SGSN), MME, PGW, SGW, etc. Network elements exist as independent physical entities. Take PGW as an example. PGW integrates many data plane functions, such as mobile IP, data packet filtering, GPRS Tunneling Protocol (GTP) tunnel management, security, and billing. Wait, there are two main problems: one is that these functions are implemented in a physical box in a tightly coupled manner, which is not conducive to introducing new functions; Wasted at low traffic and congested at high traffic.

The prior art proposes a wireless SDN architecture (Wireless SDN Architecture, WiSA for short) network architecture. In the WiSA architecture, the control plane and the data plane of the base station are separated, and the control part of the base station is extracted to form a cNB (control plane NodeB) , and extract the data plane of the base station to form a uNB (user plane NodeB). At the same time, at the network layer, the data forwarding function is concentrated on the GR (Gateway Router), and the control plane functions such as user access control and data forwarding routing control functions are placed on the centralized controller.

However, the existing technology still has the problem that the functions of the network elements cannot be decoupled.

The functions of each node in the novel network architecture shown in FIG. 1 will be described below with reference to the novel network architecture shown in FIG. 1 and the technical solution of the present invention.

The SNC is responsible for the centralized processing of the control plane and the centralized control of the user plane. In this embodiment, the SNC is mainly responsible for determining the processing path information and processing policy information of the user data according to the obtained control plane information, and processing the path information and processing policy information. The information is transmitted to the entry point and the functional nodes on the processing path; the core function of the entry point is to match the data rules. The nodes on the path can be directly indexed to the processing strategy, determine the next hop route, etc. according to the label marked by the entry point; the Function Node is not only the data forwarding function of the router/switch, but also the data processing function. Each function Nodes are limited in processing capacity (computing, storage), bandwidth, etc. The possible specific function types can also include physical layer processing function decomposition, layer two function decomposition, layer three function decomposition, video optimization, cross-layer optimization, caching (Cache), Deep Packet Inspection (DPI), etc. In data processing, functional nodes can have the same processing strategy or different processing strategies. For different processing strategies, SNC is required. Pre-provisioning or delivery one by one. The pre-provisioning method requires a processing policy indication in the packet header. If there are specific processing parameters each time, it may only be delivered one by one. The processing policy includes the processing method for the data stream, such as The compression method, compression algorithm, etc. during video compression also include data processing priority; processing parameters include specific parameters when a certain processing method is used. The functional nodes may be connected directly or through an IP network. The data forwarding within the IP network can use the SDN method or the traditional autonomous method; the wireless node can be the radio frequency remote method or the For a complete base station, the distribution entity is set to consider that there will be multiple entry points. Here, a distribution entity is introduced, which is responsible for distributing the received downlink data to multiple entry points. The policy of the distribution entity can be configured by default or can be configured by Delivered by SNC; NAT is essentially a unified interface between the access network and the external data network. The upstream and downstream data must pass through, and it is not directly related to whether there is a NAT operation.

The processing policy information includes the processing method and processing parameters for the nodes on the data path to process user data. The SNC sends the processing path information and processing policy information to the entry point, and sends the data to the data path. The functional nodes on the path send processing policy information, so that after receiving the user data, the entry point marks the user data according to the processing path information and processing policy information, and enables the functional nodes on the data path to receive the user data marked by the entry point. Then, the user data marked by the entry point is processed according to the received processing policy information, which can realize centralized control of the data path, balance the network load, and improve the utilization rate of network resources.

The above scenario of triggering the SNC execution to determine the processing path information of the data path for processing user data of the UE and the processing policy information of the nodes in the data path according to the acquired control plane information will be specifically described below.

For example, the data paths of the present invention can be divided into two types: default data paths and specific data paths, but the present invention is not limited to this. This classification is only used to describe the applicable scenarios of the technical solutions of the present invention. The path refers to the data path established for the user in advance before the user data arrives. The establishment or maintenance of the default data path includes the following three situations: first, the UE initially joins the network, second, when the UE moves, and third, the user exits the idle mode. A user service establishes a specific data path, and the factors that trigger the establishment of a specific data path include but are not limited to:

Business factor: used when a specific business needs to pass through a special node, such as video passing through a video compression node, but the default path does not pass through a video compression node;

Load factor: user data flow with large data volume needs to take a special path due to load problems;

Establishment of new services: When some special services are initially established, a special path needs to be established due to load considerations;

The function node reaches the adjustment threshold: When the load of Function Nodes is too heavy, the status is reported to the SNC, and the SNC judges that the adjustment threshold is reached and dynamically adjusts, which triggers the establishment of a specific data path.

FIG. 3 is a flowchart of Embodiment 2 of the user data processing method provided by the present invention. As shown in FIG. 3 , the user data processing method of this embodiment is aimed at establishing a default data path when the user initially accesses the network, which may include :

S201, an authorization and authentication process for network access is performed between the SNC and the UE.

Specifically, when the UE initially joins the network, the SNC and the UE perform the authorization and authentication process for network access. During the authorization and authentication process, the identity of the Radio node currently attached to the UE will be reported to the SNC, that is, the SNC obtains the authorization and authentication process. The information of the Radio node currently connected to the UE is obtained, and the specific process of this step can be operated with reference to the prior art. .

S202. The SNC sends a message to the UE that includes assigning an IP address to the UE.

S203, the UE sends an IP address reception response message to the SNC.

Specifically, considering load balancing, SNC can evenly distribute IP addresses in each network segment. After the UE receives the IP address, it sends an IP address acceptance response message to the SNC. These two messages can be sent separately, or can be carried in the interactive messages in the authorization and authentication process. The SNC receives the IP address acceptance response message sent by the UE. , that is, the determination and establishment process of the path rule for processing the user data of the UE is triggered.

S204. The SNC determines, according to the acquired control plane information, processing path information of the data path for processing user data of the UE and processing policy information of the nodes in the data path.

The data path mainly includes two aspects: processing path information and processing policy information of nodes in the data path. The processing path information includes node information on the data path (for example, including entry, FN, and Radio node) and forwarding policy information of nodes on the data path. , the processing policy information includes the processing method and processing parameters for the nodes on the data path to process user data. In this embodiment, the processing path information may be user granularity or data flow granularity.

When the SNC determines the data path, the factors that are considered mainly include: UE location information, service type, node load (including the remaining computing capacity of the node, the remaining bandwidth between nodes, the remaining storage capacity of the node, etc.), etc.;

An optional process for the SNC to determine the data path is as follows: the SNC determines the last hop location of the user according to the Radio node information currently connected to the UE obtained in S201; User service information, determine the type of functions that the user needs to go through, and get the node type on the data path; select specific functions according to the load/bandwidth/delay status information of various functional nodes mastered by the SNC itself Node, the status information of the functional node can be periodically reported to the SNC by the functional node, or the SNC can actively initiate a request to obtain; further, the processing strategy information of the functional node is obtained according to information such as contracted service information, user information, and network status; A complete data path is formed, including each functional node that the data flow passes through successively, as well as the processing strategy and processing parameters of the functional node for the data flow.

S205: The SNC sends the processing path information and processing policy information to the entry point and the functional nodes on the data path, so that after receiving the user data, the entry point marks the user data according to the processing path information, and makes the functional nodes on the data path in the After receiving the user data marked by the entry point, the user data marked by the entry point is processed according to the received processing policy information.

Specifically, the SNC sends the processing path information and processing policy information determined in S204 to the entry point Entry and the functional nodes on the data path, respectively. Generally speaking, the Entry is more concerned with the processing path information issued by the SNC, and the user data After the data packet arrives, the Entry can mark the data packet header according to the processing path information, indicating the transmission path of the data packet, so that the data packet is transmitted on the data path. Entry can also accept some processing strategies, such as scheduling priority, etc., and send it to the corresponding FN in the header of the data packet. The FN is more concerned with processing policy information, and the FN processes the user's data packet according to the processing policy issued by the SNC.

In the user data processing method provided in this embodiment, after receiving the IP address reception response message sent by the UE, the SNC triggers to determine the processing path information of the data path and the nodes in the data path according to the obtained control plane information. It can realize the centralized control of the data path, balance the network load, and improve the utilization of network resources.

S302 , the UE sends a handover request message to the SNC that includes the information of the Radio node attached to the UE after the handover, and the specific process of this step can be operated with reference to the prior art.

Specifically, during the handover process, one of the three functional entities of the UE, the Radio node to which the UE is attached before the handover, or the Radio node to which the UE is attached after the handover sends a handover request message to the SNC.

S402, the UE sends a context establishment request message to the SNC.

S403. The SNC sends a context establishment confirmation message to the UE.

Specifically, the process of establishing the context between the SNC and the UE may be included in the paging process. After the context is established in the SNC, the process of determining the data path is triggered.

S404. The SNC determines, according to the acquired control plane information, processing path information of the data path for processing user data of the UE and processing policy information of the nodes in the data path.

Specifically, the data path determination of the SNC may determine each hop node on the default data path in the manner of S204 in the embodiment shown in FIG. 3 , and the determination process is the same as that in S204 in the embodiment shown in FIG. Repeat; if the processing path information and processing strategy information of the data path of the user before the idle state are also stored in the SNC, the processing path information and processing strategy information of the established data path can also be directly used. If the radio node moves when the user is in the idle state, the last hop node Radio node is updated. If the user does not move across Radionodes in the idle state, the last hop node Radio node does not need to be updated.

S405. The SNC sends processing path information and processing policy information to the entry point and the functional nodes on the data path, so that after receiving the user data, the entry point marks the user data according to the processing path information, and makes the functional nodes on the data path in the After receiving the user data marked by the entry point, the user data marked by the entry point is processed according to the received processing policy information.

FIG. 6 is a flowchart of Embodiment 5 of the method for processing user data provided by the present invention. As shown in FIG. 6 , the method for processing user data in this embodiment is aimed at establishing a specific data path when a new service is established for a user. include:

S501. The UE and the service server perform a service negotiation process at the service level.

Specifically, when the UE has a new service to transmit, the UE conducts service negotiation at the service level with the service server, and determines parameters such as service characteristics and QoS guarantee of the service during the negotiation process. The specific process of this step can refer to the prior art. operate.

S502, the UE sends a service QoS request message including QoS parameters and service description information to the SNC.

Specifically, this step may also be that the service server sends a QoS request message to the SNC, and the QoS request message includes information such as QoS parameters and service description information, and the subsequent SNC needs to respond to the QoS request of the UE or the service server (not shown in the figure). Shows).

S503. The SNC determines, according to the acquired service quality of service parameter and/or service description information of the UE, that the service data of the UE needs to be processed by the first functional node, and the default data path of the UE does not include the first functional node.

It can be understood that, S503 can also be: SNC determines, according to the acquired service quality of service parameter and/or service description information of the UE, that the processing capability of the second functional node of the determined data path cannot meet the service quality of service requirement of the UE. .

S504. The SNC determines, according to the acquired control plane information, processing path information of the data path for processing user data of the UE and processing policy information of the nodes in the data path.

Specifically, after receiving the QoS request message, the SNC finds that the service needs to be processed in a specific FN according to the service description information and/or QoS parameters carried in it, and the default data path corresponding to the user does not pass through the FN, A determination is therefore made to establish a particular data path. When establishing a specific data path, the specific FN can be inserted into the original default path, or the method of determining the default data path in S204 in the embodiment shown in FIG. 3 can be used again to determine each node in the specific data path. In another case, the SNC determines according to the information carried in the QoS request: although there is no need to process service data at a node not included in the default path, the processing capability of a node in the original default data path is not sufficient to satisfy The resource requirement in the QoS request can also initiate the process of establishing a specific data path. At this time, the process of establishing the data path can simply be to replace the function node with insufficient resources; it is also possible to re-initiate the process in the embodiment shown in FIG. 3 . S204 is a process of determining a default data path.

S505. The SNC sends processing path information and processing policy information to the entry point and the functional nodes on the data path, so that after receiving the user data, the entry point marks the user data according to the processing path information, and makes the functional nodes on the data path in the After receiving the user data marked by the entry point, the user data marked by the entry point is processed according to the received processing policy information.

Specifically, if S504 simply adds or replaces a certain function node, the operations of Entry and/or FNs are correspondingly simpler, and only the processing strategy of the next hop node and function node needs to be re-marked locally.

In the user data processing method provided in this embodiment, the SNC determines that the service data of the UE needs to be processed by the first functional node according to the obtained service quality of service parameters and/or service description information of the UE, and the determined data path does not include After the first functional node, or after the SNC determines, according to the acquired service quality of service parameters and/or service description information of the UE, that the processing capability of the second functional node in the determined data path cannot meet the service quality of service requirements of the UE , triggering the operation of determining the processing path information of the data path for processing the UE's user data and the processing policy information of the nodes in the data path according to the obtained control plane information, or directly using the processing path information and processing policy information of the established data path , and then send the processing path information and processing policy information to the entry point and the functional nodes on the data path, which can realize centralized control of the data path, balance the network load, and improve the utilization of network resources.
