Communication device, communication system and restricting method

摘要

A communication device, a communication system, and a restricting method permitting a communication restriction for each service class. A user equipment has a memory unit which stores service class information showing correspondence between service classes indicative of available communication services, and service class codes to discriminate the service classes. A notice information receiving unit then receives a restriction message indicative of a service class number from an RNC. When the restriction message including the service class number is received, a restricting unit specifies a service class corresponding to the service class number stored in the memory unit and implements a communication restriction in the service class on a communication processing unit.
