Storage-based Location Tracking in Mobile Networks

Abstract—with the increasing number of mobile terminals, it is a challenge how to reduce the cost and provide fast and efficient call delivery to the mobile terminals. In the existing mobile networks, the call connection between the two terminals is based on the registration of their identity in the databases known as home location register and visitor location register. Conventional registration strategies will incur a high volume of signaling traffic. These strategies can work well up to a certain level of call to mobility ratio. In this paper, we propose a storage-based location tracking scheme based on the storage of the location of a mobile terminal at the repository database, which efficiently reduces the location updates and searching cost in the mobile networks.
