The present invention implements communication control with user's service subscription information reflected in a mobile communication network. A QoS control server for providing a communication quality control function of a network, a user information management server for managing user's service information, a service proxy server for transferring a service control message transmitted by a user to a service control server, a service relay server for relaying a message between service control servers in two different networks, and a service control server for exercising service control based on user service information are included. In user service start processing, the service control server or service relay server transmits a service control message inclusive of service subscription information acquired beforehand to the service proxy server. The QoS control server acquires the service subscription information from the service proxy server. Thus, subscriber information is reflected to communication quality control processing.
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,
A communication quality control method in 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,
A server comprising a network interface for conducting packet transmission and reception through a network, a storage medium for storing a service control program, a storage medium for storing user information, a CPU for executing the service control program stored in the storage medium, and a bus for mutually connecting the network interface, the storage media and the CPU,
A server comprising a network interface for conducting packet transmission and reception through a network, a storage medium for storing a service proxy control program, a storage medium for storing user information and communication quality information of users, a CPU for executing the service proxy control program stored in the storage medium, and a bus for mutually connecting the network interface, the storage media and the CPU,
A server comprising a network interface for conducting packet transmission and reception through a network, a storage medium for storing a QoS control program, a storage medium for storing communication quality information of users and communication quality information of the network, a CPU for executing the QoS control program stored in the medium, and a bus for mutually connecting the network interface, the storage media and the CPU,
