| 摘要 |
<p>The element has a receiving unit (RCP) including a loop detecting mechanism that calculates a signature e.g. alphanumeric chain, from parameters e.g. route, of input signaling messages (me) and detects a loop by comparing the signature with values inserted in a particular parameter e.g. branch parameter, of the messages. The unit sends the message to a processing unit (TRT) when the loop is not detected. The unit (TRT) transmits output signaling messages (ms) to a transmitting unit (EMS) that inserts the signature in the particular parameter of the messages (ms) based on the messages (me). The parameters conform to draft-ietf-sip-fork-loop-fix-04.txt. An INDEPENDENT CLAIM is also included for a method of transmitting a signaling message to a proxy session initiation protocol signaling intermediate element.</p> |
