Claims16
A method of operating a base station apparatus for selecting a core network in a mobile communication system, the method comprising:
- acquiring service information of a service to which a user subscribed from a service information database, which is included in the mobile communication system, or a terminal device;
- and
- selecting a dedicated core network to be used for providing a type of service to which the user subscribed, by using the acquired service information,
