Call Admission Control (CAC) in wireless communication plays major role in deciding the admission of real-time and non real-time mobile users. For non real-time, it does not care for the Quality of Service (QoS) performance. But for real-time services, the CAC cares for the QoS by keeping the sufficient bandwidth throughout the transmission. Bandwidth determines the system capacity and speed. In this paper, a new Analytic Hierarchy Process (AHP)-based CAC algorithm is proposed for increasing the number of admission and reducing the admission of less compressed calls. For this task the various codecs such as G.711, G.729, G.723, G.726, AMR, EVRC, and iLBC have been taken. AHP is applied among them to take the right decision and it produces the ranking order. That rank helps to save more bandwidth and increases the throughput (Packets per second). This task is carried out by taking the criteria like bandwidth, packetization delay, and compression ratio of each individual codecs. The ultimate aim of this TACA is to give better QoS performance for real-time services and increase the system throughput for Voice over Internet Protocol.
