METHOD AND SYSTEM TO ENHANCE PERFORMANCE OF A SESSION INITIATION PROTOCOL NETWORK AND ITS ELEMENTS

摘要

In accordance with at least one embodiment of the present invention, a communication apparatus includes a communication unit configured to send and receive messages on a network. Each message has a message header configured to include a plurality of header fields, where the message header includes a suppression header field that indicates a request to suppress at least one header field in at least one subsequently sent or received message. The communication apparatus is configured to establish a suppressed header field message exchange session with a peer on the network so that at least one subsequent message exchanged between the communication apparatus and the peer is free of at least one suppressible header field.

主权项

1. A communication apparatus, comprising:
a communication unit configured to exchange session initiation protocol (SIP) based messages with a peer on a network, wherein each SIP based message comprises a plurality of headers each comprising a text-based header field, and wherein:
a first one of the SIP based messages in a communication session omits a first set of suppressible headers of the plurality of headers with field values that are unchanged with respect to a first preceding SIP based message; anda second one of the SIP based messages in the communication session omits a second set of suppressible headers, different from the first set of suppressible headers, with field values that are unchanged with respect to a second preceding SIP based message.
