Abstract
In conventional services for communicating various media, there are limits to the number of users, the number of group lists, and the like that can be handled by servers provided by communication providers. A service system includes a server provider network 4 in addition to communication provider networks 1 to 3, and the communication provider networks 1 to 3 and the server provider network 4 are configured to be able to communicate with a PoC domain server 2 through the Internet 1. A server provider network (4) 3D having a PoC server 3D-1 and a GL server 3D-2 is also added. The user can receive services of PoC and the like from a terminal device 6 by automatically searching another server such as a server 3B-1 when users beyond the capability of a server 3A-1 simultaneously try to communicate.
