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.
