Problems solved by technology

[0005] However, in the method for determining the PCF by the above-mentioned AMF, when the terminal accesses the network each time, the AMF needs to interact with the NRF to obtain the PCF, so that the signaling overhead required for determining the PCF will be relatively large. In the method, since the AMF has selected the PCF during the process of the terminal accessing the network, and then the SMF also needs to interact with the NRF to determine the PCF during the process of establishing a PDU session between the terminal and the network, so that the signaling required to determine the PCF will be caused Expenses are relatively large

Embodiment Construction

[0158] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0159] The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific sequence of objects. For example, the first AMF, the second AMF, etc. are used to distinguish different AMFs, not to describe a specific order of AMFs.

[0160] In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodime...

Abstract

Embodiments of the present invention provide a method, device, and system for determining PCF, which relate to the field of communication technologies and can reduce signaling overhead required for determining PCF to a certain extent. The method includes: when the first AMF receives the PCF identification information sent by the second AMF, and there is a target PCF in the PCF corresponding to the PCF identification information, the first AMF acquires policy information from the target PCF, wherein the PCF identification information includes at least Identification information of a first PCF, where the identification information of the first PCF includes at least one of the IP address of the first PCF, the IP prefix of the first PCF, and the FQDN of the first PCF, and the first AMF is the The AMF that provides services for the secondary access network, and the second AMF is the AMF that provides services for the terminal's last access to the network. The method is applied in the process of the terminal accessing the network.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710967538.3 and the application title "A Method, Device and System for Determining PCF" filed with the China Patent Office on October 17, 2017, the entire contents of which are incorporated herein by reference In this application. technical field [0002] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for determining PCF. Background technique [0003] With the rapid development of communication technology, the network using the fifth generation (5G) mobile communication technology (hereinafter referred to as 5G network) is being designed and developed. In order to meet the different service requirements of the terminal, the terminal can provide Different policies control services. [0004] At present, in the 5G network, a policy control function (policy control function, PCF) c...
