Bandwidth Reservation and Admission Control Based on Mobility Predictions in Cellular Mobile Networks
Esmat Shoja, Vahid Tabataba Vakili · 2011
The scarcity of available bandwidth is one of the limitations in mobile networks and frequency spectrum must be efficiently utilized. In this paper, a call admission control (CAC) and resource reservation mechanism (RR) is described to provide a consistent QoS guarantee in cellular mobile networks and we propose an idea to improve it. This mechanism is based on user mobility profile which is effectively used for path prediction. The previous behavior of mobile users are collected and analyzed for generating mobility profiles. To make a balance between the call blocking and call dropping probabilities, non-real time new calls are queued and also advantage of variable bandwidth allocation is used with mobility prediction to improve evaluation metrics.
