Efficient Channel State Based Call Admission Control for Non Real Time traffic in LTE (3GPP) Networks
In Long Term Evolution (LTE) 3GPP Networks, several works were done on call admission control but these works rarely considers the channel quality in the controlling process. The existing techniques dont provide differentiation between the new call and the handoff call. We propose to design a call admission control algorithm based on channel state. This call admission control algorithm includes three phases: Call Classification, Channel State Estimation and Call Admission. Initially, call requests are classified into new call request and handoff call request and the type of services are classified as VoIP and Video. We prioritize HC over NC and VoIP over Video type. Then based upon the received signal strength value, the channel is estimated as good channel or bad channel. Thus from our simulation results we show that this admission control algorithm provides channel quality and prioritizes the handover calls over new calls.
