Abstract
The method and apparatus for automatically monitoring call processing transactions performed in base stations of a mobile cellular telecommunications switching system. A mobile switching center maintains a list of mobile stations whose calls are being monitored. When one of these mobile stations originates a call, or when an incoming call is received for such a mobile station, the base station originally serving the call is notified, and that base station then transmits messages recording reportable events for that mobile station. When that mobile station is handed off to another base station, the other base station receives an indication from the first base station that it is to monitor the call of that mobile station. When a base station no longer serves a mobile station that is being monitored, it clears the record that the mobile station is to be monitored from its data base. Advantageously, this arrangement has the characteristic that only base stations actually serving base stations that are being monitored, maintain a record of the base station being monitored.
