Embodiment 1

[0053] Please refer to figure 2 Embodiment 1 of the present application provides a protocol data unit session PDU session traffic offloading branch processing method, including:

[0054] S101: The session management function SMF obtains the management strategy of the PDU session traffic offloading branch;

[0055] S102: When the PDU session with the traffic offloading branch of the user equipment UE changes from the activated state to the deactivated state, based on the management policy, the SMF judges whether the PDU session satisfies a preset condition;

[0056] S103: If satisfied, the SMF deletes the PDU session flow offloading branch.

[0057] In the specific implementation process, the specific implementation process of step S101 to step S103 is as follows:

[0058] First, the session management function SMF obtains the management policy of the PDU session traffic offloading branch. In a specific implementation process, the management strategy of the PDU session traf...

Embodiment 2

[0069] Based on the same inventive concept as the first embodiment of the present application, please refer to Figure 5 , the embodiment of the present application also provides a processing device for offloading branches of PDU session traffic, including:

[0070] The session management function SMF10 includes a management strategy acquisition and storage module 101, and a management module 102 connected with the management strategy acquisition and storage module 101; wherein the management strategy acquisition and storage module 101 is used to obtain and store the management strategy of the PDUsession traffic offloading branch; The management module 102 is used to determine whether the PDU session satisfies a preset condition based on the management strategy when the PDU session with the traffic offloading branch of the user equipment UE changes from an activated state to a deactivated state; If so, the management module 102 is configured to delete the PDU session traffic o...

Abstract

The invention discloses a method and device for processing a PDU session traffic offloading branch, wherein the method includes: a session management function SMF obtains a management policy of the PDU session traffic offloading branch; When changing from the activated state to the deactivated state, based on the management policy, the SMF judges whether the PDU session satisfies a preset condition; if so, the SMF deletes the PDU session traffic offloading branch. It solves the technical problem of relatively large network signaling overhead in the processing mechanism of the local traffic offloading branch of the PDU session in the prior art, and effectively reduces the network signaling overhead.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method and device for processing offload branches of PDU session traffic. Background technique [0002] In order to support traffic offloading, the 3GPP 5G core network specifies multiple PDU session anchors in a Protocol Data Unit (PDU session). Among them, SSC (session and service continuity) mode 1 is only applied to the PDU session anchor point (ie macro anchor point) of the centralized service. [0003] In the prior art, in order to realize traffic offloading in the network, a solution of assigning an additional branch to a PDU session is proposed. Specifically, an uplink classifier UL CL method (ie, Uplink classifier) ​​and multi-home protocol data are defined. Unit session mode (that is, multi-homed PDU session mode). [0004] Among them, for the UL Classifier method, the network decides to insert an Uplink classifier into the data path of a PDU session. The ...
