As the user moves, the mobile multimedia service server 30 notifies INAITE (Hold) to the UA A to stop the service for a while to inform the previously connected communication terminal that the service is no longer in progress.

The mobile multimedia service server 30 generates a REFER including information on the UA newB for starting the Follow-Me service and delivers it to the UA A, which receives the UA A media using the media characteristic information of the new communication terminal. After the negotiation is performed, the Session Mobility Complete Flag is reset, and UA oldB is notified of NOTIFY indicating Follow-Me processing.

After UA A establishes a new session between AnewBs to provide session mobility according to the move to UA newB, UA A of the mobile multimedia service server 30 sets a session move completion flag, and AoldB and AnewB Active State, and notifies UA oldB of NOTIFY indicating completion of the transfer process.

When the UA A receives OK in the session mobility processing state, it notifies BUA to UA oldB to release the previously established session and media transmission path between AoldBs, and maintains the session only between the communication terminals where UA A and UA B are currently located. Be sure to

Therefore, using the location tracking result from the location recognition network without the user's direct control operation to ensure that the ongoing service automatically continues seamlessly to the communication terminal located in the proximity of the user moves.

After the service is terminated, all resources related to the session are initialized and idle by transmitting BYE in the same way as general call release processing.

This Follow-Me service is equally applicable regardless of whether the user's status is called or received.
