Abstract
Session Initiation Protocol (SIP) is an application layer protocol that controls multimedia sessions of Third Generation Mobile Networks. A major concern with SIP in 3G networks is ensuring the efficient use of the bandwidth constraints inherent in the wireless medium. Because of the significant size of SIP messages, 3G terminals can suffer from substantial set-up delays. IETF has proposed a general solution to this problem, named SigComp. This paper investigates the performance of SigComp, in particular how much time saving the scheme is capable of offering. A novel scheme that can replace SIP for increasing time savings and reducing the load of the SigComp layer is proposed. The scheme, referred to as Binary Hybrid SIP (BHSIP), is based on binary sequences and plain text. This paper evaluates the performance of the scheme, and compares it with normal SIP. The paper provides experimental results obtained when comparing the performance of SigComp/SIP versus SigComp/BHSIP by using an emulated network environment, and discusses the benefits of using BHSIP.
