Embodiment Construction

[0031] 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.

[0032]During the implementation of this embodiment, it was found that for the access or mobility process, due to the need to anchor the distribution gateway, in related technologies, it is possible to select different distribution gateways for multiple access systems, resulting in the inability to implement terminal IP The function of offloading data movement continuity, that is, in the related art, cannot meet the requirement of the same selection of offloading gateways in multiple access systems.

[0033] In this embodiment, the problem of unique selection of distribution gateways is considered, and a technical solution for solving the problem of selection of distribution gateways in a multi-access...

Abstract

The invention discloses a method and a device for selecting an access gateway. The method comprises the steps as follows: obtaining information of a shunt gateway of a first system accessed by a terminal, and selecting the shunt gateway as the shunt gateway of a second system according to the information of the shunt gateway when the terminal is accessed into the second system. The problem that movement continuity of IP shunt data of the terminal cannot be guaranteed is solved by the invention when the terminal is simultaneously accessed into a plurality of networks or moves among a plurality of accessed networks, and the user experience is also enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for selecting an access gateway. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (referred to as 3GPP) is formed by the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW or PDN GW for short) ), Home Subscriber Server (HSS for short), 3GPP Authentication, Authorization and Accounting (AAA for short) server, Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) ) entities and other supporting nodes. [0003] Figure 1a It is a schematic diagram 1 of the EPS system architecture according to the related technology, such as Figure 1a As shown, the mobility management entity is responsi...
