Adaptation AC to Improve Wireless Access Network Dependability

According to estimation of increasing mobile application's consumers. We are interested in Long Term Evaluation (LTE) network. LTE dependability depends on availability and reliability of his evolved Nodes Bases stations (eNB). One eNB is available when it is able yet to admit a new media and to support connection. And it is reliable when it is able to support handover connection. However we consider a dependable telecommunication service when the available and reliable system can provide an acceptable quality of service (QoS). There are works that given a higher QoS with lower dependability (availability and reliability) and works that given higher dependability with lowest QoS. We propose a new Admission Control scheme using preemption bandwidth from already connected application. Our preemption proceeds in a relative utility. Results of this work give improvement of dependability with acceptable QoS.
