[email protected]Abstract - In interworked fixed and mobile networks, both terminal mobility (TM) and personal mobility (PM) should be supported and interworked to provide seamless universal mobility to mobile users. TM supports movement between different locations with the same mobile terminal (MT). In TM management, an MT updates its location when it changes location area (LA) and an incoming call is delivered to the MT by paging all cells within a registered LA. PM supports user mobility between different terminals by using personal identifier (PID). Mobile IP is an IETF RFC that supports transparent host migration on the Internet. In the transition to IP-based cellular networks, it is widely agreed that Mobile IP provides an elegant solution for inter-domain, or macro mobility management, but lacks critical aspects of mobility management needed within cellular networks. The shortcomings have led to the recent emergence of micro mobility management protocols. In the proposed paging scheme, paging is firstly performed only to the cells containing terminals with which a user is registered for PM, instead of all cells within a registered LA. If the called user is not found in the first paging step, remaining cells within the registered LA are paged. Keywords - mobility management; paging, IP based Cellular network. 1. Introduction The move to third generation (3G) cellular network architectures is gathering pace. Both 3GPP and 3GPP2 introduced IP-based core network architectures that operate in parallel with legacy voice orientated circuit switched networks. Though IP-based core networks form part of 3G standards, mobility management is still based on No.7 signaling, specifically GSM-MAP and ANSI-41, albeit enhanced versions. This is due to the lack of a standardized IP-based mobility management protocol. In this paper we discuss the topic of an IP- based mobility management protocol suitable for deployment in future wireless networks [3]. The remainder of the paper is organized as follows: First a discussion of aspects of IPbased cellular networks is given. Next a proposed scheme termed Regional Registrations [1] is described. Traditional Public Switched Telephone Network (PSTN) telephone transmits voice or sounds by circuit switched networks, while Internet Telephony converts voice or sounds into data packets and transmits them by internet. Internet telephony uses VoIP (Voice over Internet Protocol) [4] [5] to transmit voice packets in the internet or other packet-switched networks. Currently, the most important VoIP protocol is Session Initiation Protocol (SIP) [6] that is designed by IETF. SIP is a signaling protocol and widely used for setting up and tearing down multimedia communication sessions such as voice and video calls. SIP is merely an initiation protocol for establishing multimedia sessions, and SIP uses Session Description Protocol (SDP) [7] that describes the set of media formats, addresses, and ports to negotiate an agreement between the two communication terminals as to the types of media they’re willing to share. A proxy server bases on SIP protocols is called SIP Proxy Server. In these days, one of the most widely used software for SIP Proxy Server is SIP Express Router (SER) [8] and its branch distribution OpenSER (or OpenSIPs) [9], both are open source free wares. 2. Requirements for IP-Based Mobility Management Before specifying a micro-mobility management protocol it is important to identify a generic set of requirements that must be met by any such proposal. Mobility management can be broadly decomposed into two functions: location management and handoff Chaitanya Busa et al ,Int.J.Computer Technology & Applications,Vol 3 (1), 401-405 IJCTA | JAN-FEB 2012 Available [email protected]401 ISSN:2229-6093
