摘要：
The invention discloses a technique to adequately control a handover of a user terminal in a data communication network and to decrease the number of signalings. According to this technique, when address of a user terminal (UE (101)) is not changed after a handover, UE (101) transmits a session update signaling message to carry out update processing of application session to P-CSCF 1 (121) corresponding to a location before the handover via P-CSCF 2 (123) corresponding to a location after the handover. P-CSCF 1 (121) transfers a session update signaling message to S-CSCF/AS (125) by using setup of signaling relating to UE (100) before the handover. At S-CSCF/AS (125), the application session is updated by using registration information of UE (100) before the handover.
