Problems solved by technology

[0013] In the existing UPF reselection policy control method, the SMF decides whether to perform UPF reselection, although when the SMF meets the preset trigger conditions, the third-party application can be reselected from the first UPF according to the request of the third-party application. The second UPF is selected, but since the SMF can only perform UPF reselection for one of the target applications, for other target applications that the UE is accessing, the SMF has no way to reselect these target applications from the first UPF to the second UPF , which will affect the user experience of other target applications that the UE is accessing

Abstract

The embodiment of the present invention discloses a UPF reselection policy control method, PCF and SMF. The method includes: obtaining from the SMF the event of anchor reselection in the first PDU session and the first IP of the UE corresponding to the first UPF. The validity period of the address and the second IP address of the UE corresponding to the second UPF; sending the validity period of the first IP address and the second IP address to the AFs corresponding to the respective target applications.

Description

technical field [0001] The present invention relates to mobile communication technology, and in particular to a policy control method for user plane functional entity UPF reselection, policy control functional entity PCF and session management functional entity SMF. Background technique [0002] At present, the industry is researching the next-generation wireless communication system, that is, the fifth-generation mobile communication technology (5th-generation, 5G for short). figure 1 It is a schematic diagram of the composition and structure of an existing 5G network based on a single protocol data unit PDU session. like figure 1 As shown, the 5G network includes the following functions: connection management function: mainly responsible for air interface resource scheduling of terminal access to the network and air interface connection management; authentication service function: mainly responsible for authentication and authentication of user equipment (User Equipment, ...
