1. A method for use in a network comprising steps of:
- sequentially recording in a first location electronic serial numbers of mobile stations initiating an event on the network, the first location having n storage portions to store the electronic serial numbers corresponding to the n most recent attempts of the mobile stations to originate the event on the network;
identifying an electronic serial number of a single mobile station that is recorded more than once in the first location at a given time;
recording the electronic serial number of the single mobile station in a second location; and
, identifying the single mobile station if the electronic serial number is recorded in the second location a predetermined number of times within a predetermined period of time.
