Description
Summary:In order to increase the bandwidth utilization of the CDMA system and ensure the service quality of the real-time call, this paper presents a degradation call admission control algorithm. According to the features that data service is not sensitive to the delay, it can reduce the data bit rate of non-real-time call so as to lower the load of system and meet the call need from new user. This paper brings forward design project and does system simulation, of which the result proves that DCAC can effectively decrease calls' block probability and remarkably increase the total number of the real-time on-line users. So this scheme has bright application future. (4 pages)
