ABSTRACT:
A controllable playback device is placed in a mobile station (125) which is capable of playing a recorded announcement to the user of the mobile station (125) when activated by the infrastructure equipment of the cellular communication system. The cellular communication system determines if a voice channel is available (506), and if unavailable, an estimate of a retry time period is performed (512). After the estimate of the retry time period, the system forms and sends a message to the mobile station (125) including the retry estimate (515). The mobile station (125) receives the message, and activates the controllable playback device to announce to the user of the mobile station (125) that the system is fully loaded and that an access attempt at a time related to the retry estimate would likely be successful.
