Abstract:
1. A communication quality control system which is a network system comprising a first terminal, a first radio base station accommodating the first terminal, a first QoS control server, a first user management server for managing service information of a first user of the first terminal, a first service control server, and a first service proxy server which are mutually connected in a first network, and a second terminal, a second radio base station accommodating the second terminal, a second QoS control server, a second user management server for managing service information of a user of the second terminal, a second service control server, a second service proxy server, and a service relay server for relaying a message between the first and second service control servers which are mutually connected in a second network, wherein when a QoS parameter message from the first terminal to the second terminal is received via the first network, the second service control server or the second service relay server adds service subscription information of the second user of the second terminal who utilizes service together with the first user of the first terminal to the QoS parameter message, upon receiving the QoS parameter message from the second service control server or the second service relay server, the second service proxy server records the service subscription information of the second user in a storage medium in the own apparatus, deletes the service subscription information of the second user from the QoS parameter message, and transmits a resultant QoS parameter message to the second terminal, and upon receiving a resource information inquiry message from the second QoS control server, the second service proxy server transmits the service subscription information of the second terminal recorded in the storage medium and information of resources which are being used by the second terminal to the second QoS control server, upon receiving a resource information message from the second service proxy server, the second QoS control server compares a resource parameter requested by the second user with maximum resources permitted on the basis of resources which are being used by the second user and the service subscription information of the second user, and makes a decision whether the second user can acquire resources.
