Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A system for transporting messages in a mobile communication system, comprising: a plurality of user stations; a plurality of base stations each having a backhaul interface element and each having a transceiver for carrying out time division multiple access communication with said user stations; a base station controller connected to said backhaul interface element in each of said plurality of base stations; an internal interface within each base station, connecting said backhaul interface element to said transceiver; a first set of messages for communicating signaling and user information between said user stations and said base stations; a second set of messages for communicating said signaling and user information across said internal interface; and a third set of messages for communicating said signaling and user information from said base stations to said base station controller; wherein messages from said third set of messages are transmitted in data frames comprising an opening flag, an address field, a control field, and an information field.
Claim 2
Independent Claim
161 words
A system for transporting messages in a mobile communication system, comprising: a plurality of user stations; a plurality of base stations each having a backhaul interface element and each having a transceiver for carrying out time division multiple access communication with said user stations; a base station controller connected to said backhaul interface element in each of said plurality of base stations; an internal interface within each base station, connecting said backhaul interface element to said transceiver; a first set of messages for communicating signaling and user information between said user stations and said base stations; a second set of messages for communicating said signaling and user information across said internal interface; and a third set of messages for communicating said signaling and user information from said base stations to said base station controller; wherein messages from said third set of messages are transmitted in data frames comprising an opening flag, an address field, a control field, and an information field.
