COMPRESSION METHOD, TRANSMITTER AND RECEIVER FOR RADIO DATA COMMUNICATION

An SIP/SDP compression method, transmitter (510) and receiver (550) for communicating a message from the transmitter to the receiver by, at the transmitter, removing from the message element (s) thereof and inserting into the message an indication (200) of absence of the removed element (s); and, at...

Zusammenfassung:An SIP/SDP compression method, transmitter (510) and receiver (550) for communicating a message from the transmitter to the receiver by, at the transmitter, removing from the message element (s) thereof and inserting into the message an indication (200) of absence of the removed element (s); and, at the receiver, inserting into a message received from the transmitter element (s) pre-cached at the receiver in replacement for the element (s) whose absence is indicated. This provides a lightweight SIP/SPD compression scheme (LSSCS) that (i) removes the information redundancy generated at the application layer, and (ii) can achieve 100% compression efficiency for the redundant SIP and SDP URL fields.
