Abstract

The embodiment of the invention discloses a switching method and equipment between heteroid systems. The method comprises a self-adapting safety protocol based on advance certification and a self-adapting safety protocol based on repeated certification. The embodiment is dynamically suitable for a safety structure accessed to a network technology by the self-adapting protocol, introduces a restructurable technology based on cognitive radio to the system, simultaneously imports an interconnection acting NIA entity, obtains latest trusty neighbor switching information by mobile historical information of a subscriber, realizes safety certification among different networks by adopting the advance certification and a safety context transmission technology, and also reduces the switching time delay. In addition, the invention can also use a method of the repeated certification, dynamically selects an optimal neighbor switching network from NIA and realizes the safety certification among different networks.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for switching between heterogeneous systems. Background technique [0002] The next-generation broadband wireless network is an ALL-IP (all-IP) network composed of different heterogeneous wireless access networks. It integrates various access networks to provide users with unified services. The third-generation mobile network 3GPP is currently formulating the EPS (Evolved Packet System) standard for the 3GPP evolved network. The 3GPP evolved network can integrate UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial Radio Access Network), EUTRAN (Enhanced UTRAN, enhanced UTRAN) and other access networks such as WLAN (Wireless Local Access Network, wireless local area network) and WIMAX (World Interoperability for Microwave Access, World Interoperability for Microwave Access) access systems are integrated together. like...
