In personal communications, users communicate via wireless
with a wireline backbone network. The wireline backbone network
tracks the current location of the user, and can therefore route
messages to a user regardless of the user's location. Mobile
tracking is impact on signaling within the wireline backbone
network and requires the expenditure of wireless resources,
including the powerconsumption of the mobile terminals carried
by users and the radio bandwidth used for location update and
terminal paging. In this thesis we study a mobility tracking
mechanism that combines a distance-based location update
strategy with selective paging scheme. In addition, we consider
the impact if the location database is updated whenever a mobile
user requests for a call connection. Therefore considering only
call arrival rate is not efficient for mobility tracking. The
combinative consideration of the incoming call arrival rate and
the requests for a call connection rate have impact on the
choice of the distance threshold used in location update. We
provide an analytical model for the proposed mobility tracking
mechanism which captures the mobility rate, the incoming call
arrival rate and the request for an outgoing connection rate of
each mobile terminal.
