Embodiment 1

[0238] Figure 5a The flow chart of the PFDF providing the packet flow description information provided by the application to the appropriate UPF provided by Embodiment 1 of the present invention. This embodiment is based on Figure 4aIn the architecture shown, the PFDF is arranged separately from the NEF. Such as Figure 5a shown, including the following steps:

[0239] Step 501: The application (such as a third-party service capability server / application server (Services CapabilityServer / Application Server, SCS / AS for short)) sends a PFD management request message to the NEF, the PFD management request message carries the SCS / AS identifier, and the application provides Service Provider (SP for short) reference identifier, external Application Id (application identifier), PFD requested to be added or modified, and corresponding location information.

[0240] Among them, an application may deploy application servers in multiple regions to achieve load sharing or nearby acc...

Embodiment 2

[0265] Figure 5b It is a flow chart of the PCF providing the packet flow description information provided by the application to the appropriate UPF according to the second embodiment of the present invention. This embodiment is based on Figure 4c In the architecture shown, the third-party application provides the PFD to the PCF through the NEF. Such as Figure 5b shown, including the following steps:

[0266] Step 5a01: The application (such as SCS / AS) sends a PFD management request message to the NEF, and the PFD management request message carries the SCS / AS identifier, the SP reference identifier, the external Application Id, the PFD requested to be added or modified, and the corresponding location information .

[0267] Among them, an application may deploy application servers in multiple regions to achieve load sharing or nearby access. Therefore, for the same external Application Id, the PFDs corresponding to different location information are usually different.

Embodiment 3

[0291] Figure 6 It is a flow chart of introducing UL CL when a PDU session is established, and activating distribution rules by SMF. Such as Figure 6 shown, including the following steps:

[0292] Step 601: UE initiates an attach process and completes network registration;

[0293] Step 602: The UE sends a PDU session establishment request message to the AMF, and the PDU session establishment request message carries a user identifier and a data network name (Data Network Name, DN Name);

[0294] Step 603: After the AMF selects a SMF, forward the PDU session establishment request message to the selected SMF;

[0295] Step 604: The SMF interacts with User Data Management (UDM for short), obtains subscription information of the user, and verifies the UE. Wherein, the subscription information of the user carries a UL CL permission indication;

[0296] Step 605: the SMF assigns an IP address to the UE. The SMF sends a policy request message to the PCF, and the policy reques...

Abstract

The invention discloses a service flow division implementation method and a service flow division implementation device. The method comprises the steps as follows: after acquiring an application identifier, grouping flow description corresponding to the application identifier and appropriate position information of the grouping flow description from an application, a control plane function provides the grouping flow description to a user plane function corresponding to the appropriate position information of the grouping flow description, so that the user plane function performs flow divisionon service data corresponding to the application identifier. According to the scheme provided by the invention, the grouping flow is described on the corresponding user plane function via the positioninformation, so as to achieve the flow division of the service.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for realizing service distribution. Background technique [0002] figure 1 It is a schematic diagram of the architecture of a 4G (4th Generation, fourth generation) network in related technologies, such as figure 1 As shown, each network element in the network architecture includes: [0003] The terminal (User Equipment, referred to as UE) mainly accesses the 4G network through the wireless air interface and obtains services. The terminal exchanges information with the base station through the air interface, and communicates with the core network through the Non Access Stratum Mobility management unit exchange information. [0004] The base station (Radio Access Network, referred to as RAN) is responsible for air interface resource scheduling and air interface connection management for terminal access networks, and is also responsible for detecting user u...
