Apparatus, method and system for subscriber control of timed and regional membership in multiple member termination groups for multiple leg telecommunication sessions

摘要

A system, apparatus and method are provided for subscriber control of timed and regional membership in multiple member termination groups for multiple leg telecommunication sessions, such as for providing outgoing call legs for a flexible alerting service, to different groups of members, at different times of day or different geographic locations. The preferred system includes a home location register coupled to a mobile switching center. The home location register has, stored in a memory, a plurality of secondary directory numbers associated with a primary directory number, and includes instructions to determine whether each secondary directory number, of the plurality of secondary directory numbers, is currently incorporated within a selected alerting group based upon a predefined time period parameter or a geographic location parameter for a mobile unit corresponding to the secondary directory number. The mobile switching center has an interface for receiving an incoming call leg designating the primary directory number and for differentially processing and routing each outgoing call leg associated with each secondary directory number currently incorporated within the selected alerting group.
