an identification information processor configured to determine a service content of a service to be used by the communication terminal, and to set a piece of identification information to be used by the communication terminal from among the pieces of identification information corresponding to the determined service content by referring to the pieces of correspondence information; and
the communication terminal includes an information holding unit configured to hold the piece of correspondence information notified by the network side communication device,
the service content of the service to be used by the communication terminal is changed when the network side communication device selects the address among the default address and the additional address,
