Abstract
A method and system of completing calls to busy mobile subscribers in a radio telecommunications network. The system includes a gateway mobile switching center (G-MSC) to provide switching functions to a mobile station (MS) in a home service area, a home location register (HLR) providing a location of the MS to the G-MSC, a visitor mobile switching center (V-MSC) to provide switching functions to the MS when the MS roams outside the home service area, and a service control point (SCP) which includes service logic for periodically initiating a call attempt to the MS to determine if the MS is busy. When the calling party attempts to call a busy MS, the calling party may request an automatic callback service. The G-MSC releases all trunks from the calling party and the MS and notifies the SCP. The SCP periodically initiates a call attempt to ascertain whether the MS is idle. Upon determining that the MS is idle, the G-MSC connects the call between the calling party and the MS.
