- Abstract
- In this paper, we propose a new call admission control (CAC) scheme for wireless cellular systems supporting a hot-spot cell. Two strategies for CAC are assumed. One is based on the number of calls, which are accepted or not, the other is based on the interference level. The proposed CAC can regulate the call attempts with packet by adopting measured interference used for matrix. A function, specifically a linear interpolation function based on Inverse Transform theory is used to convert controlled predictive average admission ratio in a call rejection ratio. Then, a call admission ratio is obtained from the call rejection ratio. Numerical results show that the proposed scheme yields better performance than the conventional scheme does under the heavy calls on a hot-spot cell.
