Problems solved by technology

[0004] However, during the BDT negotiation process, AF does not provide user identification information
If the PCF only selects the unified data repository (UDR) based on the NF service name and NF type, there will be a UDR selected

Abstract

The invention provides a method, a device and a system for managing a background data transmission strategy. A strategy control function network element can obtain the background data transmission strategy corresponding to a terminal. The method comprises the following steps: a first policy control function network element receives a first message, the first message carries a first identifier, andthe first identifier can be a background data transmission reference identifier or an application function identifier; then, a second message is sent to the first data storage network element so as to obtain a background data transmission strategy, and the second message carries the first identifier; and finally, a third message from the first data storage network element is received, and the third message comprises a first background data transmission strategy corresponding to the first identifier.

Description

[0001] This application claims priority to a Chinese patent application with application number 201910523169.8 and titled "Method, device and system for managing background data transmission strategies" filed with the China Patent Office on June 17, 2019, the entire contents of which are incorporated by reference in this application. technical field [0002] The present application relates to the field of communications, and more particularly, to a method, device and system for managing background data transmission policies. Background technique [0003] In the current background data transfer (BDT) mechanism, it mainly includes the following three processes: (1) Background data transfer policy negotiation, specifically, the application function (AF) can pre-negotiate the background data with the operator network Data transmission policy; (2) background data transmission policy is sent to UE as part of user equipment (UE) route selection policy (UE route selection policy, UR...
