Abstract

Abstract An apparatus for providing a call interception capability includes a master call intercept database storing records of subscribers of a global mobile satellite communications system targeted for call interception by law enforcement agencies. The apparatus also has a visitor location register storing records of subscribers currently registered within a serviceable vicinity of a gateway earth station associated with said visitor location register. The apparatus further includes a target database storing records of registered subscribers targeted for call interception, and an intercept coordinator communicating with the master call intercept database and the visitor location register. The intercept coordinator stores in the target database a record of a targeted subscriber, when the visitor location register includes a corresponding record of the targeted subscriber. The intercept coordinator optionally removes a record of a targeted subscriber from the target database, when the visitor location register does not include a record of the targeted subscriber.
