Abstract

An origination terminal UA100 in accordance with the present invention is provided with a control unit 320 for controlling, when receiving information indicating that a destination terminal uses a network different from a network desired by an originator, so as to transmit a call enable notification request requesting the destination terminal, when the destination terminal UA200 can connect to the network desired by the originator, to transmit a call enable notification notifying the originator accordingly. The destination terminal UA200 in accordance with the present invention is provided with a control unit 320 for controlling, when receiving the call enable notification request from the origination terminal UA100, so as to transmit the call enable notification when the destination terminal UA200 can connect to the network desired by the originator.

Claims

1. A communication apparatus comprising:

a transmission unit for transmitting a call request including information on a condition of a wireless communication system of a called side desired by a calling side by use of a predetermined communication system; and

a control unit for controlling, when receiving information indicating that the called side uses a wireless communication system not satisfying the condition of the wireless communication system of the called side desired by the calling side in response to the call request transmitted by the transmission unit, so as to transmit a call enable notification request requesting the called side, when the called side can connect to a wireless communication system satisfying the condition of the wireless communication system of the called side desired by the calling side, to transmit a call enable notification notifying the calling side accordingly.

2. 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; and

a control unit for controlling, in a case of receiving a call enable notification request, which is a message requesting the 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 notify the calling side accordingly, in response to a response by the response unit, so as to transmit a call enable notification, which is a message notifying that the called side can connect to a wireless communication system satisfying the condition by use of the wireless communication system when it is connectable to the wireless communication system.

3. The wireless communication apparatus according to claim 2, further comprising a request reception unit for receiving the call enable notification request, a determination unit for determining whether to grant the call enable notification request received, and a cancellation unit for cancelling use of the predetermined wireless communication system used by the response unit when determining to grant the call enable notification request received.

4. The wireless communication apparatus according to claim 3, wherein the determination unit, by comparing the call enable notification request received to a condition of a mode which has been set in advance, determines whether to grant the call enable notification request received based on the mode.

5. The wireless communication apparatus according to claim 3, wherein the determination unit, by comparing the call enable notification request received to a condition of a notification party which has been set in advance, determines whether to grant the call enable notification request received based on the notification party.

6. A communication control method comprising:

a transmission step for transmitting a call request including information on a condition of a wireless communication system of a called side desired by a calling side by use of a predetermined communication system; and

a control step for controlling, when receiving information indicating that the called side uses a wireless communication system not satisfying the condition of the wireless communication system of the called side desired by the calling side in response to the call request transmitted at the transmission step, so as to transmit a call enable notification request requesting the called side, when the called side can connect to a wireless communication system satisfying the condition of the wireless communication system of the called side desired by the calling side, to transmit a call enable notification notifying the calling side accordingly.

7. 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; and

a control step for controlling, in a case of receiving a call enable notification request, which is a message requesting the 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 notify the calling side accordingly, in response to a response of the response step, so as to transmit a call enable notification, which is a message notifying that the called side can connect to a wireless communication system satisfying the condition by use of the wireless communication system when it is connectable to the wireless communication system.
