A mobile communication system having a layered architecture communicates user and signaling data among components of the communication system in the form of information elements which are encapsulated within packets and which may be passed across one or more system interfaces. The mobile communication system may comprises mobile user stations, base stations, and base station controllers and operates as a transparent data pipeline between application end users, such as a telephone service, connected at base station controllers and mobile user stations. Each system interface functions as a communication channel between system components, providing the lower layers of a layered communication system architecture. In a particular embodiment, the interface between the base station and the user stations is a TDMA interface, and the interface between a base radio transceiver and a line card processor comprises a dual-port RAM which is used as a shared resource across the interface. Prioritized queues may be used to facilitate response to relatively urgent signaling and control messages. |
