Summary:
In this paper we review two multirate loss models, whereby we can assess the call-level QoS of the Long Term Evolution (LTE) X2 link supporting calls of different service-classes with fixed bandwidth requirements. The X2 interface connects directly two neighboring evolved NodeBs and is mainly responsible for the transfer of user-plane and control-plane data during a handover. In both models, the X2 interface is modeled as a link of fixed capacity. Handover calls are accepted in the X2 link whenever there exists available bandwidth. Otherwise, calls are blocked and lost. For the evaluation of both models we compare the QoS index of congestion probabilities, under the same offered traffic-load conditions. Analytical congestion probabilities results show that both models perform equally well in most cases.
