Abstract:

At present, the location management scheme in mobile communication systems ignores the impact of periodic location updates, which leads to the degradation of the performance of the network for terminal location tracking, and a location tracking scheme combining mobility and periodicity is proposed. First, the terminal initiates a location update request to the network whenever it crosses the boundary of the tracking area list or when the timer reaches the threshold. Then, the network calls first initiate paging to the tracking area where the last location update of the terminal occurred, and then initiates paging to the tracking area list if the call is unsuccessful. Finally, the signaling overhead of location update and paging is derived using a Markov chain model. The simulation experimental results show that the proposed scheme obtains the optimal configuration of the tracking area list, thus minimizing the total signaling overhead.

Key words:

mobile communication, location management, location updates and paging, tracking arealists, Markov chains
