COMMUNICATION CONTROL SYSTEM, COMMUNICATION CONTROL METHOD AND COMMUNICATION CONTROLLER
First Claim
1. A communication control system that connects a call using a local service number valid within a local service area within which user equipment is positioned, and forwards data via an internet protocol network, comprising:
- a local number converter that is located in each local service area that, in response to a query specifying a local service number, accesses a database of correspondence between a local service number valid within the local service area and a global routable number, and determines a global routable number corresponding to the specified local service number; and
a session controller group that accepts a call request including the local service number from the user equipment, queries the local number converter in the local service area within which the user equipment is positioned to convert the local service number into a global routable number, and routes the internet protocol network using the global routable number.

Abstract
A communication control system connects a call using a local service number valid within a local service area within which a user equipment is positioned, and forwards data via an internet protocol network, including a local number converter and a session controller group. The local number converter is located in each local service area, in response to a query specifying a local service number, accesses a database of correspondence between a local service number valid within the local service area and a global routable number, and determines a global routable number corresponding to the specified local service number. The session controller group accepts a call request including the local service number from the user equipment, queries the local number converter in the local service area to convert the local service number into a global routable number, and routes the internet protocol network using the global routable number.

11. A communication control method in a communication system that connects a call using a local service number valid within a local service area within which a user equipment is positioned, and forwards data via an internet protocol network, comprising:
-
accepting a call request including a local service number from the user equipment; among local number converters that are located in each local service area, in response to a query specifying a local service number, accessing a database of correspondence between a local service number valid within the local service area and a global routable number, and determining a global routable number corresponding to the specified local service number, querying a local number converter in a local service area within which the user equipment is positioned to convert the local service number into a global routable number; and routing the internet protocol network by using the global routable number. - View Dependent Claims (12, 13)

14. A communication controller used with a local number converter that is located in each local service area, in response to a query specifying a local service number, accesses a database of correspondence between a local service number valid within the local service area and a global routable number, and determines a global routable number corresponding to the specified local service number:
-
in a communication control system that connects a call using the local service number valid within the local service area within which a user equipment is positioned, and forwards data via an internet protocol network, wherein a query is put to a local number converter in the local service area within which the user equipment issued a call request including the local service number is positioned to convert the local service number into the global routable number.
