We propose and present a new access persistence control mechanism for packet cellular networks, such as General Packet Radio Service (GPRS) system, in order to improve the MAC layer performance. The MAC layer in GPRS make use of slotted ALOHA protocol combined with a specific retransmission mechanism to establish the physical connection. The main object of the new mechanism is to avoid the mixture of retransmitted access request and the new ones. The primary profit is the decrease of the transmission attempts number needed to successfully transmit an access request. Thus, it decreases the delay of transmission of one access request and the access requests blocking percent
