Embodiment Construction

[0060] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0061] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.

[0062] method embodiment

[0063] The inventor believes that in the future 5G software architecture, there may be no distinction between SGW UPF and PGW UPF. UPF can be universal, and the connection relationship between UPF and a certain CPF should not be limited. The topological relationship between UPF and CPF It can be adjusted flexibly and dynamically.

[0064] Based on the above considerations, a method for managing UPF is provided in this embod...

Abstract

The invention provides a user plane function (UPF) management method, device and system. The method comprises the steps of acquiring capability information of one or more UPFs in a preset area; and selecting a designated UPF for a terminal with a CPF accessed from the one or more UPFs according to the capability information of the one or more UPFs. Through adoption of the UPF management method, device and system, the UPF can be adjusted flexibly and dynamically, the topology of the control function and the forwarding function of the 4G network is improved, and the UPF is managed and selected more flexibly.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system for managing UPF (User plane function, User plane function). Background technique [0002] figure 1 is a schematic structural diagram of a 3GPP evolved packet system according to related technologies, such as figure 1 As shown, the 3GPP Evolved Packet System (EPS, Evolved Packet System) consists of an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), a Mobility Management Unit (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (PDN GW or P-GW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server), 3GPP Authentication Authorization Accounting (AAA, Authentication, Authorization and Accounting) server, Policy and Charging Rules Function entity (PCRF, Policy and Charging Rule...
