Abstract

A cellular communications system may include at least one base station and at least one mobile cellular communications device. More particularly, the at least one mobile cellular communications device may include a controller, at least one user input device connected to the controller, and a wireless transceiver cooperating with the controller for attempting to establish a wireless communications link with at least one base station, and if the wireless communications link cannot be established, then continuing to attempt to establish the wireless communications link at a first attempt rate. Moreover, if a user provides a request to access the at least one base station via the at least one user input device, then the controller may continue to attempt to establish the wireless communications link based upon a second attempt rate greater than the first attempt rate.
