US 5,852,777 A · Method and apparatus for screening a call in a wireless system

Abstract

A method and apparatus for screening a call in a telecommunications network having a first system comprising a first subscriber station and a second system comprising a second subscriber station, associated with the first subscriber station by a predetermined relationship. Each subscriber station in the first system has a unique subscriber number and the second system having a general number for all subscriber stations. In the method and apparatus, call setup requests for calls to the general number of the second system are screened to determine if the call was originally made to the number of the first subscriber station and then forwarded to the general number of the second system, or if the call was originally made to the general number. If the call was originally made to the first subscriber station, only the second subscriber station is alerted. If the call was originally made to the general number, all the subscriber stations in the second system are alerted.

Dependent claims

In a telecommunications network having a first system comprising a first plurality of subscriber stations, each assigned a unique subscriber number and a second system comprising a second plurality of subscriber stations, all assigned a single common subscriber number, wherein a first and second subscriber station of said first and second plurality of subscriber stations, respectively, are associated by a predetermined relationship, a method of screening a call, said method comprising the steps of:

receiving a setup request for a call to the common subscriber number assigned to said second plurality of subscriber stations;
determining whether said setup request was forwarded following a call setup attempt to a selected subscriber number assigned to said first subscriber station;
and,
if it is so determined, selectively alerting only said second subscriber station of said second plurality of subscriber stations;
else, alerting each of the second plurality of subscriber stations.
