WIPO Patent Application WO/2019/076199
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to the technical field of communications, and provide a method, apparatus and system for determining a PCF, capable of reducing to a certain extent signaling overhead required for determining a PCF. The method comprises: a first AMF receives PCF identification information sent from a second AMF, and when a target PCF exists in PCFs corresponding to the PCF identification information, the first AMF obtains policy information from the target PCF, wherein the PCF identification information comprises identification information of at least one first PCF, the identification information of the first PCF comprising at least one of an IP address of the first PCF, an IP prefix of the first PCF, and an FQDN of the first PCF, the first AMF is an AMF for providing a service when a terminal accesses a network this time, and the second AMF is an AMF for providing a service when the terminal accesses the network the last time.
