Abstract
There is disclosed a wireless communications network in which a group of base stations are served by a mobile switching center that maintains a master data record for all missed calls from mobile devices in all base station coverage areas. Missed call data are stored in different priority level queues in each of the bases stations. When a call is missed in a first base station coverage area, a time stamp or a sequence number for the missed call is stored in the mobile switching center. If the mobile device moves into a second base station coverage area, the mobile device re-originates the missed call. The second base station receives from the mobile switching center the priority level of the re-originated call and the time stamp or unique sequence number from the mobile switching center. If the second base station does not have a traffic channel available, the second base station puts the missed call in the proper priority level queue and, within that proper priority level queue, can use the time stamp or the sequence number to determine the priority of the missed call relative to the pre-existing missed calls already in the priority level queue.
