Abstract :
This paper demonstrates the efficiency gains achievable for the compression scheme SigComp using extended operations where information from previously sent and received messages is used. The calculations are performed for a call setup using SIP in a typical 3GPP scenario. It is estimated that the transmission time over the air interface can be reduced by approximately 2/3. Also, the performance in terms of compression efficiency can be doubled, compared to using message by message compression with SigComp.
