Paging in Mobile Terminals using Mobility Management in Fixed and Mobile Networks

Terminal mobility(TM) and personal mobility (PM) should work together to provide mobility to mobile users in fixed and mobile networks. TM supports movement between different areas with in the same region. In mobility management, an MT (Mobile Terminal) updates its location when it changes its location and all calls are delivered to the MT by paging all cells within that registered location area (LA). In PM personal identifier (PID) is used to identify users at different terminals. In PM all users’ information is registered at registrar and an incoming call is delivered to the registered terminal based on registered information. Since location management in TM generates a lot of signaling messages over radio interface and consumes scarce radio resources, it is essential to reduce the number of location registration and paging signaling messages, i.e., signaling load. We propose an efficient paging scheme for TM in fixed and mobile networks, by using registration information for PM management. 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.
