PROBLEM TO BE SOLVED: To efficiently control a service to a user's terminal without acquiring environmental information related to the user's terminal on a service provider side.;SOLUTION: In this service control system, a service user terminal 40 extracts, when it detects an environmental change of the own device, environmental information related to the changed environment and transmits hashed environmental information to a network agent 30. The network agent terminal 30 performs an evaluation request related to the hashed environmental information to an environmental management station terminal 10. The environmental management station terminal 10 calculates an evaluation value to the environmental information and transmits the calculated evaluation value to the network agent terminal 30. The network agent terminal 30 transmits status change information to the service provider terminal 20, and the service provider terminal 20 updates a user DB 25a and controls the service to be provided to the service user in reference to the user DB 25a and a service policy DB 25c.;COPYRIGHT: (C)2007,JPO&INPIT
