1. A mobile telecommunication system, comprising:
- a mobile station;
a home location register associated with the mobile station, wherein the home location register stores a mobile subscriber profile and maintains information indicative of a mobile station'"'"'s location;
a visiting mobile switching center (V-MSC) having a service area wherein said mobile station is presently located, a paging mechanism for paging said mobile station, and a switching mechanism for establishing a voice channel between the V-MSC and the mobile station;
a gateway mobile switching center (G-MSC) for receiving and routing an incoming call to the mobile station, said G-MSC having a signaling mechanism for signaling the home location register and a switching mechanism for routing calls to the V-MSC;
a means for determining that the incoming call will not be completed; and
a means for directing the telecommunication system to drop radio resources prior to call setup between the G-MSC and the V-MSC.

Abstract
A system and method for stopping call setup in a mobile telecommunication system having a home location register (HLR), a visiting mobile switching center (V-MSC) and a subscriber mobile station (MS). Upon determining that a call to the subscriber mobile station is being dropped by the calling party, or upon determining that calls are not to be routed to the mobile station when the mobile station is located in the service area of the V-MSC, a release resources message is transmitted to the HLR and the V-MSC stopping the paging process or releasing the system resources, including any such resources associated with seizure of a voice channel between the V-MSC and the MS.
