- FIG. 14 is a flowchart of the service proxy server (4).
- the service proxy server (4) performs initialization processing at startup and starts an event processing loop (F4-01, 04). In the event processing loop, user terminal (1) If a QoS parameter message is received (F 4-07), the service proxy server. (4) will check whether the QoS parameter message contains the service parameter of another user terminal (1). (F4-22). If the service parameter is not included, the service proxy server (4) displays the user ID, service communication port number, and Qo S parameter included in the QoS parameter message as the user QoS information DB (442 ) (S 4-23). If the service parameter is included, the service parameter is set to the user information DB (4
- the Qo S parameter message is sent to the appropriate destination (F4-25).
- a service start request is received (F4-10)
- a message is sent to an appropriate destination.
- a resource information inquiry message is received (F 4-13)
- a resource information message is sent to the QoS control server (3) (F4-28).
- the event processing loop ends when the service proxy server (4) shuts down (F4-16), and after stopping the event processing loop, the service proxy server (4) stops functioning (F4-19). ).
- FIG 15 is a flowchart of the service control server (5) and service relay server (7).
- a service control server will be described as an example.
- the service control server (5) performs initialization at startup and starts an event processing loop (F 5-01, 04).
- the service control server includes the service parameter of another user terminal (1) in the Qo S parameter message.
- Investigate whether the force is present F 5— 07). If the service parameter is included, send the QoS parameter message to the appropriate destination (F 5-22). If the service parameter is not included, the service control server (5) acquires the service parameter of the destination user from the user information DB (541) and assigns it to the message (F 5-25), and then sends the message.
- a service control server or a service relay server obtains service subscription information registered by a user at the time of service subscription from the user information management server prior to service control.
- the service proxy server includes the user service subscription information in the service control message and sends it to the service proxy server, so that the service proxy server responds to the query from the QoS control server in response to the network resource.
- the user's service subscription information can be sent to the QoS server.
- the QoS control server reflects the user's service subscription information in addition to the network resource usage status. Communication quality control processing can be performed. Industrial use possible '1 life
- the service control server, the service relay server, and the service proxy server realize the communication quality control reflecting the user service subscription information in the mobile communication network. It can be applied to a communication quality assurance type audio / video call system on a physical communication network.
