“…This action is called location update. Many researches were thus proposed in the past for making a good trade-off between the costs of these two actions (Chintalapati, Kumar, & Datta, 1997;Han & Cho, 2004;Kruijt, Sparreboom, Schoute, & Prasad, 1998;Ma & Fang, 2002;Wang et al, 2000).…”

“…Also, the user profile for a particular user in the UPDBR algorithm is assumed to be under the same switch { (MSC) as used in Reference [20]. When many switches are involved in retrieving the user profile, the proposed technique may incur a longer call set up { In current cellular network standards such as GSM and IS-41 [2,14], a number of BSs are connected to a base station controller (BSC). The BSC is connected to a MSC, which is attached to the public networks.…”

SummaryWe propose a unified framework consisting of a differential bandwidth reservation (DBR) algorithm and a Quality of Service (QoS)-aware admission control scheme to provide QoS guarantees to on-going connections in cellular networks. The differential bandwidth reservation policy uses a sector of cells in making the bandwidth reservation for accepting a new call. Based on the distance of the target cells in the sectors, two different bandwidth reservation policies are applied to optimize the connection dropping rate (CDR), while maintaining a competitive connection blocking rate (CBR). In addition, two possible mobile terminal (MT) movements are analyzed using the DBR mechanism. In the first case, no knowledge of an MT's moving path is assumed to be known, while in the second case, prior knowledge of an user profile is used in bandwidth reservation, and it is called user profile-based DBR (UPDBR) algorithm. Using the DBR scheme, we propose an admission control algorithm that uses varying number of cells in a sector to meet admission decisions. Extensive simulation is performed to evaluate our methodology.Comparison of the proposed scheme with two prior schemes shows that our approach is not only capable of providing better QoS guarantees, but is also flexible in terms of using varying number of cells in satisfying the high-level QoS requirements.

“…Thus, the optimal location area is given by a single cell, which, in turn, minimizes paging costs [19]. Stationary users on fixed schedules exhibit this type of behavior.…”

Third-generation mobile systems provide access to a wide range of services and enable mobile users to communicate regardless of their geographical location and their roaming characteristics. Due to the growing number of mobile users, global connectivity, and the small size of cells, one of the most critical issues regarding these networks is location management. In recent years, several strategies have been proposed to improve the performance of the location management procedure in 3G mobile networks. In this paper, we present a user pattern learning strategy (UPL) using neural networks to reduce the location update signaling cost by increasing the intelligence of the location procedure in UMTS. This strategy associates to each user a list of cells where she is likely to be with a given probability in each time interval. The implementation of this strategy has been subject to extensive tests. The results obtained confirm the efficiency of UPL in significantly reducing the costs of both location updates and call delivery procedures when compared to the UMTS standard and with other strategies well-known in the literature.
