Communication terminal 200a ..... includes a plurality of mobile communication terminal 200 of the n-th mobile communication terminal 200n.

In the present embodiment, the external server 100 is located in an IP Multimedia Core Network Subsystem (hereinafter referred to as "IMS") 10. The IMS 10 refers to a communication system that provides IP multimedia services to subscribers through an IP-based core network.

In the IMS 10, a Session Initiation Protocol (hereinafter referred to as "SIP") is used to provide connectivity with an existing Internet network and independence of an access network. The SIP protocol is used as a signaling protocol for creating / modifying / ending IP multimedia service sessions. On the other hand, its role is to exchange information for controlling a message session between subscribers who want to exchange messages.

The external server 100 includes a management server 100a and a storage server 100b.

The management server 100a performs user authentication and registration procedures for a user's registration request, sets up SIP sessions for registered users, and manages multiple SIP sessions for each user.
