In future wireless communication networks such as 4G, different wireless technologies and architectures will coexist. In these heterogeneous network environments, mobility management is a critical issue. Session Initiation Protocol (SIP) is a widely discussed protocol, which is used for signaling and mobility management, especially in Voice over IP (VoIP) environment. However, its mobility management is restricted to SIP sessions only. To provide a full mobility management for services in future wireless IP networks, SIP can be combined with other protocols. In this paper, a new mobility management scheme based on Host Identity Protocol (HIP) and SIP is proposed. The hybrid SIP and HIP (SHIP) scheme is for all services. SHIP has better performance in handoff signaling than SIP. Its signaling overhead is smaller and the signaling delay is much shorter. SHIP has been shown to outperform hybrid SIP and Mobile IP, a widely discussed mobility management scheme, in a number of areas.
