Abstract

The adjacent network includes user terminal affiliated source network, one or more objective networks neighboring to source network. The switch management server (SMS) in source network is configured in service switching management server. The method includes steps: context-sensing server in source network collects and processes relevant context information (RCI) of user terminal; based on RCI to generate switching trigger event; RCI includes network information of source network, network information of target network, and terminal information; SMS in source network and SMS in target network to be switched to carries out switching management for the switching trigger event; under switching management, user terminal is switched to target network from source network. The invention also discloses a kind of switch equipment in use for isomeric network across domains, and isomeric network system across domains.

Description

technical field

[0001] The present invention relates to the communication field, and more specifically, to a cross-domain heterogeneous network system and a handover method and device between adjacent networks. Background technique

[0002] With the rapid development of communication technology, new communication technologies and standards emerge one after another, and the communication industry is experiencing a new period of development and transformation. In the process of communication network developing towards high-speed, broadband and personalization, a variety of wireless communication technologies and networks have emerged, including: 2G (GSM), 2.5G (GPRS), 3G (UMTS), WLAN, WiMax , PAN, fixed network, etc., which brings rich heterogeneity to the communication network, and heterogeneity will also be one of the main characteristics of the wireless network environment for a long time in the future. Therefore, research on the interworking and integration of heterogeneo...
