Abstract
Paging is an important mobile network procedure that is performed to locate and
connect mobile users when they receive calls/sessions. It is needed as users are
mobile, and continuously updating their serving cells is not bandwidth efficient.
In traditional broadcast paging, all cells of a network are grouped into clusters
that are identified by Location Area Code (LAC). Users update their LAC and
network look for a paged user by sending paging messages for all cells within the
user’s LAC. A decision on cluster size is an important factor that determines the
paging overhead and connection delay. The larger cluster size, the smaller LAC
update but the larger capacity for the paging message. To minimize the capacity
required for paging messages while maintaining a larger cluster size, profile-based
paging has been proposed and studied. Yet, such a paging approach has not been
investigated and applied for Addis Ababa third-generation network.
In this thesis work, we analyzed the performance of profile-based paging algorithm
for Addis Ababa third-generation network based on call detail record data
collected from the network management system and compared it with conventional
one. The algorithms considered were static and dynamic profile based paging.
We analyzed the paging algorithms for users with less, moderate and highly
mobile. A user’s mobility is modeled using a Markov model.
Achieved results show that the profile-based algorithm considerably increases the
efficiency of utilization with slight or no effect in the overall paging success rate.
