METHOD AND DEVICE FOR UPDATING ACCESS NUMBER OF USER EQUIPMENT

摘要

A method and device for updating access number of user equipment sets a reallocation logic module for implementing reallocation of UE access number, and presets corresponding relation between UE location information and UE access number therein. After obtaining the UE location information, the reallocation logic module reallocates UE access number according to the current location information and synchronizes the allocated UE access number to call executing point UE or gsmSCF and UE. The method of the present invention can realize reallocation of UE access number and update of UE current access number according to UE location information in time, ensure that VMSC can recognize UE access number, make UE complete call handover successfully at CS call when handing over call from IMS domain to CS domain, increase the satisfaction of user and enhance the reliability of network. Further, the present invention provides a method of dynamic UE access number for UE, makes CS domain complete the call handover from IMS domain to CS domain without obtaining routing information by CAMEL interaction, and therefore improves the efficiency of handover.
