ABSTRACT:
A first router receives an original IS-634 standard frame formatted message over an A-bis interface from a base transceiver station. The first router identifies header information bits in the message for compression. The first router suppresses selected ones of the identified header information bits and encapsulates the message into a packet. A second router receives the packet from the first router and extracts the message from the packet. The second router reconstructs the selected ones of the header information bits that were suppressed by the first router. The second router regenerates the original IS-634 standard frame formatted message and transports the message to a base station controller over the A-bis interface.
