1. A method, comprising:
determining, by a processing system including a processor of a mobile device, a timing value of a preliminary transmission from a wireless access terminal of a mobile cellular network, wherein the preliminary transmission is received before a successful completion of an attachment process between the mobile device and the wireless access terminal;
determining, by the processing system, a displacement between the mobile device and the wireless access terminal according to the timing value;
comparing, by the processing system, the displacement to a threshold value to obtain a comparison result; and
preventing, by the processing system, the successful completion of the attachment process based on the comparison result indicating the displacement violates the threshold value, wherein the threshold value comprises a distance threshold.
