Abstract

A destination terminal UA200 in accordance with the present invention, which is a wireless communication apparatus capable of using a plurality of different wireless communication systems, is provided with a control unit 320 for determining, in a case where the destination terminal UA200 receives a call enable notification request from an origination terminal UA100, whether a desired network satisfies a condition to transmit the call enable notification based on a condition of the desired network and a required bandwidth for a desired application when the destination terminal UA200 becomes connectable to the desired network, and for controlling so as to transmit the call enable notification when the desired network satisfies the condition to transmit the call enable notification, while controlling so as to transmit a condition deterioration notification when the desired network does not satisfy the condition.

Claims

1. A wireless communication apparatus capable of using a plurality of different wireless communication systems comprising:

a message reception unit for receiving, with regard to a call request to be transmitted from a calling side later, an initiation message including a communication condition desired by the calling side and a request requesting use of at least one of the plurality of different wireless communication systems to receive the call request;

a response unit for responding to the initiation message received so as to receive the call request by use of a predetermined wireless communication system among the plurality of wireless communication systems;

a control unit for controlling so as to cancel use of the predetermined wireless communication system used by the reception unit, in case of receiving a call enable notification request requesting a called side, when the called side can connect to a wireless communication system satisfying a condition of a wireless communication system of the called side desired by the calling side, to transmit a call enable notification notifying the calling side accordingly, in response to a response by the response unit; and

a memory unit for storing a transmission condition of the call enable notification,

wherein the control unit determines whether it is connectable to a wireless communication system satisfying the condition, when it is connectable to the wireless communication system satisfying the condition, determines whether the wireless communication system satisfies the transmission condition of the call enable notification stored in the memory unit and, only when determining that the wireless communication system satisfies the transmission condition, controls to transmit the call enable notification by use of the wireless communication system.

2. The wireless communication apparatus according to claim 1, wherein the control unit, when determining that the wireless communication system which has been determined as satisfying the transmission condition of the call enable notification does not satisfy the transmission condition of the call enable notification, controls so as to transmit a condition deterioration notification notifying that a condition of the wireless communication system is deteriorated by use of the wireless communication system.

3. A communication control method capable of using a plurality of different wireless communication systems comprising:

a message reception step for receiving, with regard to a call request to be transmitted from a calling side later, an initiation message including a communication condition desired by the calling side and a request requesting use of at least one of the plurality of different wireless communication systems to receive the call request;

a response step for responding to the initiation message received so as to receive the call request by use of a predetermined wireless communication system among the plurality of wireless communication systems;

a cancellation step for controlling so as to cancel use of the predetermined wireless communication system used at the reception step, in case of receiving a call enable notification request requesting a called side, when the called side can connect to a wireless communication system satisfying a condition of a wireless communication system of the called side desired by the calling side, to transmit a call enable notification notifying the calling side accordingly in response to a response at the response step;

a memory step for storing a transmission condition of the call enable notification; and

a transmission step for determining whether it is connectable to a wireless communication system satisfying the condition, when it is connectable to the wireless communication system satisfying the condition, for determining whether the wireless communication system satisfies the transmission condition of the call enable notification stored at the memory step and, only when determining that the wireless communication system satisfies the transmission condition, for controlling to transmit the call enable notification by use of the wireless communication system.
