Embodiment 1

[0073] see image 3 , the figure shows a method for identifying service data flow, which is characterized in that it includes:

[0074] Step 301. Determine the general service data flow identifier, the general service data flow identifier includes one or more service data flow characteristic items describing the service data flow;

[0075] The above general service data flow identification can be represented by General Flow Identification (GFI);

[0076] The above service data flow characteristic item can be represented by Flow Characteristic Item.

[0077] In this embodiment, the general service data flow identifier (GFI) may include: a first field and a second field, wherein the first field represents the number (Count) of service data flow characteristic items, and the second field represents the service data flow Feature, which describes the feature information of the service data flow, the feature information includes one or more feature items of the service data flow, ...

Embodiment 2

[0125] see Figure 4 , in the new generation network architecture, the control plane function (or called control plane functional entity) and user plane function (or called user plane functional entity) of the network are respectively composed of Control Plane (CP) function(s) and UserPlane (UP ) function(s) implementation. Among them, UP can be flexibly deployed in different positions of the network, such as Local-UP deployed near the base station / network edge, CN-UP deployed at a higher position in the network, etc.; and CP may be deployed in the form of cloud, and may be The control plane function is reconstructed into one or more independent logical nodes (for example: MM (Mobility management, mobility management), SM (Session management, session management) and so on). If a Policy function (or called a policy function entity) is deployed in the network, it will be able to obtain the ability to implement finer control through policy information.

[0126] On the basis of ...

Embodiment 3

[0140] see Figure 4 , in the framework of CU separation (separation of control plane functions and user plane functions), on the basis of the first embodiment above, the following subsequent delivery and processing can be completed:

[0141] Solution a: The core network control plane function is delivered to the core network user plane function, and / or,

[0142] Solution b: The core network control plane function sends the type identifier of a specific service data flow (the type identifier can be standardized or assigned by the operator), and the core network user plane function obtains it from its own provisioning policy based on the identifier The corresponding (no-protocol) representation.

[0143] see Figure 6 , the figure shows the process of issuing a general service data flow identifier, and the specific steps are as follows:

[0144] Step 1, Establishment of PDU Session, that is, establish a PDU session;

[0145] Step 2, Flow Description Policy Obtainment, that ...

Abstract

The embodiment of the invention provides a method and apparatus for identifying service data streams. The method comprises the following steps: determining a general service data stream identifier, wherein the general service data stream identifier comprises one or more service data stream feature items for describing the service data streams; and identifying the service data streams to be judgedaccording to the service data stream feature items in the general service data stream identifier. The general service data stream identifier not depending on a specific protocol can be used for identifying and distinguishing the service data streams, identifying and processing of cross-protocol service data streams are achieved by the clustering processing of multiple general service data stream identifiers, and the method and apparatus are suitable for identifying multiple types of service data streams such as IP, Non-IP (non-IP), and Ethernet frame (Ethernet Frame Format).

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for identifying service data flow. Background technique [0002] The current mobile communication network EPS (Evolved Packet System, evolved packet system) architecture (taking non-roaming scenarios as an example) is as follows: figure 1 shown. [0003] From figure 1 It can be seen that the UE accesses the network through E-UTRAN (evolved unified terrestrial radio access network), and communicates directly / indirectly with the control plane network element MME and the user plane network element Serving Gateway / PDN Gateway through E-UTRAN. interaction. It is worth noting that UE's user plane messages are sequentially forwarded and processed through E-UTRAN, Serving Gateway, and PDNGateway, and finally realize UE's support for PDN connection services between external PDN networks. [0004] The concept of packet data network (PDN) connection ser...
