ABSTRACT:
A method is disclosed for operating a wireless communications system that includes a BMI (32) that is bidirectionally coupled to a communications network (36) and at least one wireless mobile station (10) that is bidirectionally coupled to the BMI. The method includes the steps of (a) queuing in the BMI a call originated by the mobile station; (b) at a time that a BMI resource, such as a traffic channel, is available for completing the queued call, determining if the call can be completed; and (c) for the case where the call cannot be completed, sending a message to the mobile station for indicating that the queued call cannot be completed. The message is sent before a traffic channel is allocated to the mobile station. In this manner the mobile station can be signalled that the queued number is unavailable, but without first allocating a traffic channel to the mobile station. The method further includes a step, executed during a time that the call is queued, of sending a second message to the mobile station for indicating that an incoming call has been received for the mobile station. The mobile station is responsive to the second message for sending a third message to the BMI, the third message indicating that the BMI is to cancel the queued call so that the mobile station can receive the incoming call. More particularly, the second message can indicate at least one of that (a) the BMI is to leave the queued call pending while not connecting the incoming call to the mobile station, or that (b) the BMI is leave the queued call pending while connecting the mobile station to the incoming call.
