Summary:PROBLEM TO BE SOLVED: To reduce loads in a network and a presence server in simultaneous login from a terminal unit of the presence server. SOLUTION: A buddy list storage means 1a stores a buddy list. A version storage means 1b stores version information. A version transmission means 1c outputs version information when log-in operation ends normally. A buddy list database 2a stores the buddy list before login operation. A version database 2b stores server-side version information. A version comparison means 2c compares the server-side version information with version information to determine coincidence or noncoincidence, and outputs a coincidence determination signal and a noncoincidence determination signal for coincidence and noncoincidence, respectively. A buddy list transmission means 2d reads the server-side buddy list for outputting when it receives the noncoincidence determination signal. COPYRIGHT: (C)2007,JPO&INPIT
