<p><P>PROBLEM TO BE SOLVED: To provide policy control by each service, to a service that uses a protocol other than SIP (session initiation protocol). <P>SOLUTION: In a communication method, when a control server 4 connected to a network receives a service request, a resource control device 8 is inquired of resource approval information; and when it is approved, the service request is accepted. The resource control device 8 transmits approved policy information to an AGW (access gateway device) 6. The AGW 6 uses the received policy information to execute priority control, or the like. Accordingly, even when a control procedure other than the SIP is to be used to provide service, a network resource and priority control that is based on a network policy and service information can be performed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
