Effect of personal mobility management in mobile communication networks

Personal mobility (PM) is one of the key issues in realizing personal communications service (PCS) in emerging thirdgeneration mobile communication networks such as International Mobile Telecommunication 2000 (IMT-2000). It can be realized through universal personal telecommunication (UPT) service. Two PM management schemes are proposed to manage PM information related to UPT users for incoming call (incall) registration/deregistration, incall registration reset by a mobile terminal (MT) owner, and incall delivery to UPT users in mobile communication networks based on the location information managed by the user’s home network. The relative cost, i.e., the ratio of cost per unit time for supporting both terminal mobility (TM) and PM management to that of TM management, is derived, and the effect of PM management is analyzed from the aspects of update or query cost, signaling delivery cost, and processing cost. These results can be utilized in the implementation of PM management in IMT-2000.
