<p><P>PROBLEM TO BE SOLVED: To clarify the corresponding state of each domain to a network resource in response to a QoS request from a user. <P>SOLUTION: A first terminal of a first network and a second terminal of a second network perform QoS communication astride the respective networks. The communication equipment of the first network transmits a session start request including request QoS information from the first terminal to the second network. The communication equipment of the second network checks whether to allow the securement of a communication resource for achieving QoS shown by the request QoS information in the second network. When the communication resource cannot be secured, first penalty charging information for paying a penalty charge to the first network from the second network is registered, and the request QoS information is changed in accordance with the communication resource secured in the second network and reported to the communication equipment of the first network. The communication equipment of the first network checks whether to allow the securement of a communication resource for achieving QoS shown by the request QoS information in the first network. When the communication resource cannot be secured, second penalty charging information for paying a penalty charge to the second network from the first network is registered. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
