US 6,445,915 B1 · Apparatus, method and system for providing variable termination patterns for multiple telecommunication sessions

Abstract

An apparatus, method and system are disclosed for providing variable termination and alerting patterns, based upon call progress information, for multiple leg telecommunication sessions, such as for flexible alerting. The preferred wireless system embodiment includes a home location register (HLR) and a mobile switching center (MSC). The HLR stores a plurality of secondary directory numbers(with corresponding routing parameters) associated with a pilot directory number. The MSC differentially processes and routes each outgoing call leg associated with each secondary directory number, to form a plurality of outgoing call legs. As the various outgoing call legs may be answered, not answered, released, have routing failures, or return busy signals, the MSC generates, and transmits to the HLR, corresponding call progress and status information. Based upon such information, the HLR may dynamically vary the termination and alerting patterns for outgoing call legs corresponding to the secondary directory numbers. When the call progress and status information indicates a misrouting of an outgoing call leg of the plurality of outgoing call legs, the HLR has instructions to delete a secondary directory number corresponding to the misrouted outgoing call leg from the first plurality of secondary directory numbers, which will create a different termination pattern for the next session. The HLR also includes instructions, when the call progress and status information indicates a variance from subscriber parameters, to adjust a termination and alerting pattern corresponding to the first plurality of secondary directory numbers, such as increasing or decreasing routing parameters, including timing delay parameters and no answer time parameters.
