Extended proxy-call session control function block in next generation network based on IP Multimedia Subsystem and mobility management method using the same

摘要

The present invention provides an extended proxy call session control function blocks and using the same mobility management in next-generation IMS-based networks relates to a method, a mobile station The method includes performing a proxy call session control function and extended for managing the mobility of the mobile node proxy control function (Extended Proxy-Call Session Control Function: hereinafter, P-CSCF +) block to a S sending a registration request message for the -CSCF block; The P-CSCF + block delivering storing location information of the mobile terminal, the registration request message to the S-CSCF block; And the S-CSCF in this block comprises the step of performing a registration for the mobile terminal based on a registration request message received the transmission. According to the present invention, the introduction of an additional protocol in the next generation of the IMS-based network can be easily provided without the need for a location management function for the mobile terminal.
