Abstract Group paging can simultaneously activate hundreds of user equipments (UEs) using a single paging message. Upon receiving the group paging message, all UEs should immediately transmit their paging response messages through the random access channels (RACHs). Simultaneous channel access from a huge group of UEs may result in severe collisions of the RACHs during a very short period of time. In this paper, we propose a pre-backoff method to reduce the collision probability of random access requests. We develop an analytical model to investigate the performance and optimize the setting of the pre-backoff method. The accuracy of the analytical model is verified through computer simulation. Results show that the proposed pre-backoff method can effectively enhance the performance of group paging.
