  • System using international roaming-capable mobile communication network
    Patent number: 8774796
    Abstract: The present invention provides a system using an international roaming-capable mobile communication network in which a server controls the form in which a service is provided in accordance with the country of a service area in which a mobile station is located. The mobile station 1 determines the service area in which the mobile station 1 is located in accordance with a mobile communication mode set by a mobile communication mode setting function. Alternatively, the mobile station 1 determines the service area in which it is located through notification information relating to a mobile communication network system, received from a base station. When the mobile station 1 transmits a request for a service to a content provider server 4, the mobile station 1 simultaneously adds a region header describing the determined service area. A gateway G/W63 may add the region header instead of the mobile station 1.
