Abstract: The system, apparatus and method of the present invention provide telecommunication conferencing services in a multiple leg telecommunication session. One of the system embodiments includes a database and a switching center. The database has stored in a memory a plurality of secondary directory numbers and a conference parameter associated with a primary directory number. The switching center has an interface for receiving an incoming call leg designating the primary directory number and for determining whether the primary directory number and its associated plurality of secondary directory numbers are configured for a conference mode.

Abstract: 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.

Abstract: An apparatus, method and system are disclosed for providing call progress and status information for multiple leg telecommunication sessions, such as for flexible alerting, for intelligent network services. The preferred wireless system embodiment includes a home location register and a mobile switching center. The home location register stores a plurality of secondary directory numbers associated with a pilot directory number. The mobile switching center 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 mobile switching center generates corresponding call progress and status information.

Abstract: A wireless communications system provides call transfer capability for an incoming call to a mobile subscriber unit. The mobile subscriber unit requests the call transfer to a serving MSC. The serving MSC relays the request to a home location register, and the home location register executes the request by initiating the call transfer in conjunction with an originating MSC. This arrangement obviates the need for supporting call transfer on the serving MSC and the need for inter-MSC facilities once the call transfer is completed. Moreover, the approach of the present invention enables call transfer to be ubiquitously supported within a wireless communications system.

Abstract: Method and apparatus for suppressing route request messages for wireless gateway applications by establishing a relationship between a serving mobile switching center identifier and a facility identifier at a wireless gateway switch. The wireless gateway switch determines a corresponding facility to the serving mobile switch in order to establish an incoming call to a wireless subscriber unit. An exemplary embodiment exploits the present invention in a wireless system utilizing ANSI-41 messaging.

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.

Abstract: An apparatus, method and system are provided which, for a wireless telecommunication session handled by a mobile switching center, allow an adjunct network entity, such as an intelligent peripheral, a service node, a service control point, or another switching center, to maintain control over the telecommunication session and, in the preferred embodiment, provide intelligent network services. Such control is provided without the adjunct network entity monitoring or maintaining a direct connection the telecommunication session, such as a voice path or other circuit-based connection.

Abstract: A system, apparatus and method are disclosed which provide variable alerting patterns for multiple leg telecommunication sessions, such as for providing concurrent alerting, sequential alerting, pyramid alerting or cascade alerting, of outgoing call legs for a flexible alerting service. 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, such as an ANSI compatible pilot directory number, and for each secondary directory number of the plurality of secondary directory numbers, further stored in the memory a corresponding timing delay parameter, a corresponding no answer time parameter, and a corresponding no answer termination trigger. Variation of the various corresponding timing delay parameters and no answer time parameters produces the variable alerting patterns.

Abstract: An apparatus, method and system provide for conditional answering in multiple leg telecommunication sessions, such as in a flexible alerting service. The preferred system includes a home location register (HLR) coupled to a mobile switching center (MSC). The HLR has, stored in a memory, a plurality of secondary directory numbers associated with a primary directory number, such as an ANSI compatible pilot directory number. The MSC has an interface for receiving an incoming call leg designating the primary directory number and for processing and routing each outgoing call leg associated with each secondary directory number. Following reception of a directive from the HLR, the MSC obtains information from a calling party to create called party information. When an outgoing call leg has been conditionally answered, the MSC provides the called party information on the conditionally answered outgoing call leg.
