NETWORK-SLICE CONTROL SERVER, SERVICE SERVER, AND RESPECTIVE CONTROL METHODS THEREBY

Abstract:

A service server of a service provider issues an instruction for switching regarding a network slice to be applied to a user terminal. The network-slice control server receives, from the service server of the service provider, the instruction for switching to the network slice to be applied to the user terminal. The network-slice control server transmits, to a subscriber management server, an instruction for changing subscriber information regarding the user terminal, on the basis of the instruction for switching to the network slice received from the service server. Thus, the subscriber information regarding the user terminal is changed in the subscriber management server.
