Improving SigComp performance through extended operations
Mats Nordberg, Hans Hannu, Jan Christoffersson, L. Zaccomer · 2003
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.
