ABSTRACT:
A signaling method reduces bandwidth requirements and signaling delays normally associated with sending text-based signaling messages over a wireless links. An application at a transmitting endpoint generates and sends a binary-encoded signaling message, along with a binary interpreter that enables the receiving endpoint or SIP server to construct a text-based message from the binary encoded message. The binary-encoded signaling message may include references to a saved state, or to a dictionary to enable compression of the message. The signaling method can be used with any text-based signaling protocol, such as the Session Initiation Protocol, the Session Description Protocol, and the Real Time Streaming Protocol.
