Embodiment Construction

[0049] First, an overview of the principle of the present invention is given. On the one hand, the handover method in the evolved network provided by the present invention is that when an active state handover occurs, if an inter-LMHA handover occurs, if the AT uses a simple IP in the source LMHA, it is the AT Re-allocate the IP address or prefix information belonging to the target LMHA subnet and notify the AT to re-establish the connection; CAP sends agent notification (for mobile IPv4) or route notification (for mobile IPv6) to AT, and then performs mobile IP registration to HA to establish connection. In the case of simple IPv6 or mobile IPv6, AT obtains a global unicast address through IPv6 stateless auto-configuration.

[0050] On the other hand, in order to further improve the continuity of the business and avoid the handover delay effect caused by the change of the IP address of the AT during the handover, when an inter-LMHA handover occurs, the solution of the present...

Abstract

The disclosed switch method in wireless evolution network (WEN) comprises: when AT switches, Capp or LMHA decides whether there is a switch between LMHA; if yes, selects the proper treatment way. This invention reduces resource waste and system complexity, and provides more experience for user.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a handover technology in a wireless evolution network. Background technique [0002] In order to maintain the competitiveness of the future system of the 3rd Generation Partnership Project 2 (3GPP2, 3rd Generation Partnership Project2), research on long-term evolution (LTE, Long Term Evolution) and system architecture evolution (SAE, System Architecture Evolution) in network evolution is ongoing . 3GPP2 standard organization's ongoing network evolution project research is mainly concerned with the long-term evolution of IP packet networks. The main purpose of network evolution is to enhance packet switching capability, simplify network structure, improve service quality (QoS, Quality of Service), reduce delay, increase user data rate, increase system capacity and coverage, reduce operating costs, etc., so that the evolved The packet network can more effectively provide the b...
