System and method for hunting trunk lines with a GSM wireless base station and GSM wireless infrastructure employing the same

A system and method, associated with a wireless base station system ("BSS") coupled to a mobile service center ("MSC") via a plurality of trunk lines, that allow the BSS to hunt the plurality of trunk lines for available channels to carry calls from the BSS to the MSC and a Groupe Speciale Mobile ("GSM") wireless infrastructure employing the system or the method. The system includes: (1) a signaling controller, associated with the BSS, that sends a command signal to the MSC to cause the MSC to bypass hunting for the available channels, the MSC acknowledging bypassing of the hunting to the signaling controller and (2) a trunk hunting controller, associated with the BSS, that is enabled when the MSC acknowledges the bypassing of the hunting to allow the BSS to hunt the plurality of trunk lines for the available channels to carry the calls from the BSS to the MSC, the trunk hunting controller capable of utilizing the trunk lines more efficiently than the MSC.
