Group paging is one of the solutions proposed to deal with the radio access network overload problem resulted from machine-type communications. In group paging, the base station normally reserves a fixed number of radio resources during the paging cycle and thus, results in inefficient usage of the radio resource. This paper presents a dynamic resource allocation (DRA) scheme to adjust the reserved resource during the paging cycle based on the estimated number of contending devices in each random access slot. Analytical model is then presented to find the optimal value of design parameters of DRA subject to a given QoS constraint. Simulation results demonstrate the effectiveness of the proposed DRA algorithm.
