Abstract: A method and apparatus for completing a priority call to a wireless border switch. A priority or preemption request is transmitted as part of the signaling messages used to set up a call. A border switch is a switch which is used in conjunction with the switch indicated by the last-seen pointer from an HLR entry for the called terminal to page a called station. The switch indicated by the last-seen pointer transmits the priority request to a border switch, to indicate that the call should be given priority treatment. Further, preemption service for calls terminating on a wireless station can be provided.

Abstract: A method and apparatus for selectively controlling the connection of a call to a monitoring station, as well as to a called party. Callers and called parties are required to identify themselves through the use of a Personal Identification Number (PIN), or some device such as a thumb reader. A database maintains a list of legitimate personal identification numbers, and of those personal identification numbers or thumb prints which require that a call be monitored. Advantageously, law enforcement agencies can control the monitoring of a call from or to a particular party as identified by a personal identification number or a thumb print, no matter where the call originates or terminates.
