Method and device for selecting network device in switching process

Abstract

The embodiments of the present invention provide a method and apparatus for selecting a network device during switching. The method comprises: receiving a switching request message which is sent by a user equipment and used for indicating to switch an access network used by a session of the user equipment to a first access network from a second access network; acquiring a first access point name used when the user equipment accesses a core network through the second access network and an identification of a first packet data network gateway corresponding to the first access point name; and selecting the first access point name as an access point name used after the session of the user equipment is switched to the first access network, and selecting a packet data network gateway indicated by the identification of the first packet data network gateway as a packet data network gateway used after the session of the user equipment is switched to the first access network. By adopting the present invention, when a UE is switched between access networks, the IP address will not change, thereby effectively avoiding the problem of transmission interruption of IP data streams of the UE.

Description

Technical field [0001] The invention belongs to the field of communications, and in particular relates to a method and a device for selecting network equipment in a handover process. Background technique [0002] The third generation mobile communication network is implemented in accordance with the standards formulated by the 3GPP (3rd Generation Partnership Project) standards organization. It can be referred to as mobile communication network or 3GPP network for short. It is currently the most widely used wide area mobile network. Communications network. And WLAN (Wireless Local Access Network, wireless local area network), as a local area communication network with convenient access, fast speed and relatively low price, has also been widely deployed and used. Users can use UE (User Equipment, user equipment) to access 3GPP network or WLAN network for data services, such as accessing the Internet, downloading text / audio / video data, etc. [0003] The UE can also access the 3GPP ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the embodiments of the present invention is to provide a method and device for selecting network equipment during handover, aiming to solve the problem of interruption of IP data stream transmission when UE is handed over from a non-3GPP access network to a 3GPP access network
