Consider a cell serving a homogeneous delay-sensitive application (e.g. video telephony). New and handover sessions arrive at the cell following independent Poisson processes with intensities λn and λh, respectively. The sojourn time of each session follows an exponential distribution with the parameter μ. The cell can accommodate Ntot sessions in total. In order to prioritize handover sessions, we consider a probabilistic reservation scheme described as follows: • Handover sessions are always accepted as long as there is capacity. • When there are currently x sessions in the cell, a new session is accepted with the probability of 1 x+1 (x <>
