This thesis presents a new location management technique for
cellular mobile communication networks. Location management is an
essential service in mobile communication networks. The location update and search are the two important parts of any location management
technique. There is a trade-off between location update and search, when a mobile terminal moves.
The proposed location management technique is introduced with
its two parts to reduce the overhead produced when the mobile terminals
frequently move to the same regions. Current location management
techniques (such as GSM) are done inefficiently lI1 this case. The
proposed location management technique is based on registration or
valuable information about the subscriber such as the visited cells, and the time at which these cells were visited. These two variables are
considered very important from technical part of view. Then, the
registered information will be used to build a profile for each subscriber.
These profiles will be used to predict the subscriber location for incoming
calls. So, the proposed technique is a memory based technique and it
depends on the habits of the subscribers or subscribers’ movements. The performance of the proposed technique is evaluated in terms of the total cost of location updates and searches. The proposed technique and the
other techniques are implemented and simulated. The simulation results
are used to compare between these techniques.
