Abstract

Provided are a packet data gateway selection method, and a related device and system, which can fuse some / all of the logic functions of a 3GPP AAA server to a mobility management network element. With regard to a UE accessing from a non-3GPP side, the mobility management network element, or the mobility management network element and a non-3GPP access gateway achieve the selection of a target P-GW, which not only simplifies a network architecture, but also can adapt to the simplified network architecture to achieve the selection of the P-GW.

Description

technical field

[0001] The present invention relates to the technical field of communication, and in particular to a method, a related device and a system of a packet data gateway. Background technique

[0002] In order to meet the challenge of wireless broadband technology and maintain the leading edge of the 3rd Generation Partnership Project (3GPP) network, 3GPP formulated a long-term evolution (Long Term Evolution, LTE) plan for mobile communication networks at the end of 2004. Under the guidance of the plan, a new mobile communication network architecture is defined, such as figure 1 shown. This architecture is flatter than the second generation (2G) network and the third generation (3G) network, and only retains the packet switching (Packet Switching, PS) domain, so it can be called the evolved 3GPP packet switching The domain (Evolved 3GPP Packet Switched Domain) may also be called an evolved packet system (Evolved Packet System, EPS).
