ABSTRACT:
A system and method of ensuring that a called mobile station's expected service type matches a calling party's service type in a radio telecommunications network in which both voice service and data service are provided. A service code generator in a serving mobile switching center (MSC) generates a service code that indicates the calling party's service type. The service code is sent in a page from the serving MSC to the mobile station, and includes the service code. An expected service code generator in the called mobile station generates an expected service code that indicates the called mobile station's expected service type. The expected service code is sent in a page response from the mobile station to a border MSC that borders the serving MSC. The border MSC extracts the expected service code and sends it to the serving MSC where it is compared with the calling party's service code. If the service codes match, the call is connected to the mobile station. If the service codes do not match, the mobile station is denied access to the radio telecommunications network.
