Resource allocation control device, resource allocation control method, and mobile communication system

A resource allocation control method for allocating or assigning the resource in communication between a radio access network, which has a base transceiver station to which a mobile station is connected and a base station controller which is connected to said base transceiver station, and an IP network, comprising:

• a corresponding step of corresponding radio access channels used for communication between said mobile station and said base transceiver station, and transmission/reception ports used for communication between said radio access network and said IP network;
• a storing step of storing the information on said corresponded radio access channels and transmission/reception ports;
• and
• an allocation/assignment step of allocating or assigning one of said radio access channels and said transmission/reception ports to the other, based on the information on said corresponded radio access channels and transmission/reception ports.

A mobile communication system, comprising:

• a radio access network which has a base transceiver station to which a mobile station is connected and a base station controller which is connected to said base transceiver station;
• an IP network;
• and
• a resource allocation control device connected to said radio access network and said IP network, comprising corresponding means for corresponding radio access channels used for communication between said mobile station and said base transceiver station, and transmission/reception ports used for communication between said radio access network and said IP network, storing means for storing the information on said corresponded radio access channels and transmission/reception ports, and allocation/assignment means for allocating or assigning one of said radio access channels and said transmission/reception ports to the other, based on the information on said corresponded radio access channels and transmission/reception ports.
