A mobile switching center (MSC) in accordance with the principles of the present invention provides access to a subscribers voice message center from the subscriber's roaming mobile station. The MSC is responsive to a &ldquo;RemoteFeatureRequest&rdquo; Invocation by the roaming mobile station in which the subscriber's directory number is the same as the dialed digits by routing the call from the mobile station to the subscriber's voice message center. The MSC may also be responsive to a &ldquo;OriginationRequest&rdquo; employing the subscriber's directory number as the dialed digits by routing the roaming mobile station's call to the subscriber's voice message center. If the MSC supports both RemoteFeatureRequest-, and OriginationRequest-based access to the subscriber's voice message center, the MSC determines which of the approaches to use in response to the reception of a subscriber's directory number as the dialed digits from the subscriber's roaming mobile station. The MSC may make this determination on the basis of information stored in a local database that indicates the method employed by other telecommunications devices, such as other MSCs, Visiting Location Registers (VLR), or Home Location Registers (HLR), within the system. One of the methods, that is, the use of an Origination Invocation or the use of a RemoteFeatureRequest invocation, may be chosen as a default method.

Alternative message usage for voice mail retreival via revertive calling

The present invention provides a method for limiting the number of simultaneous call forwarding attempts for a mobile unit. A call is made for a mobile unit. The call request is sent to the MSC associated with the mobile unit. When the mobile unit is not currently active at the MSC, the MSC sends a location request to an SCP. The SCP responds with a return message that includes a temporary location directory number (TLDN) and an indicator. The MSC checks the current number of simultaneous call forwarding attempts being made for the mobile unit. If the current number of simultaneous call forwarding attempts exceeds a threshold, the MSC does not forward the call. If the number of simultaneous attempts does not exceed a threshold, the MSC forwards the call to the mobile unit by sending it to the TLDN.

Method for limiting the number of simultaneous call forwarding attempts in a cellular communication system

An apparatus, method and system are provided for automatic telecommunication conferencing and broadcasting. The system embodiment includes a switch for reception of a first incoming call leg designating a multiple leg service, such as a telecommunication conference, and also designating a subscriber group. Each particular subscriber group is predefined, and consists of a list of directory numbers to be included within the conference or broadcast session. The system embodiment also includes a conference bridge coupled to the switch, in which the conference bridge includes instructions to receive the first incoming call leg routed from the switch, to determine the plurality of directory numbers associated with the subscriber group, and to return to the switch a plurality of intermediate incoming call legs corresponding to the plurality of directory numbers for routing by the switch to form a plurality of outgoing call legs. The conference bridge also includes further instructions to monitor answering of the plurality of outgoing call legs, and to connect an outgoing call leg indicating joinder, of the plurality of outgoing call legs, to the conference bridge for a multiple leg telecommunication session, such as a conference or broadcast session.

Apparatus, method and system for automatic telecommunication conferencing and broadcasting

An apparatus, method and system are provided for roamer originated automatic telecommunication conferencing and broadcasting. The system embodiment includes a first switch for reception of a first incoming call leg from a roaming mobile unit or from another telecommunication device outside its assigned serving area. The first incoming call leg preferably designates a multiple leg service, such as a telecommunication conference, and also designates a subscriber group. Each particular subscriber group is predefined, and consists of a list of directory numbers to be included within the conference or broadcast session. In the various embodiments, the first switch communicates with a second switch or a database, and obtains a routing directory number to reroute the first incoming call leg, to form a second incoming call leg to the second switch. The system embodiment also includes a conference bridge coupled to the second switch, in which the conference bridge includes instructions to receive the second incoming call leg routed from the second switch, to determine the plurality of directory numbers associated with the subscriber group, and to return to the second switch a plurality of intermediate incoming call legs corresponding to the plurality of directory numbers for routing by the second switch to form a plurality of outgoing call legs. The conference bridge also includes further instructions to monitor answering of the plurality of outgoing call legs, and to connect an outgoing call leg indicating joinder, of the plurality of outgoing call legs, to the conference bridge for a multiple leg telecommunication session, such as a conference or broadcast session.

Apparatus method and system for roamer originated automatic telecommunication conferencing and broadcasting

The invention provides systems, including a methods and apparatus, for providing seamless telephone service across MSC's that support multiple or different protocols. In accordance with a preferred embodiment of the invention, the home mobile switching center, where the subscriber record is stored, is equipped to respond to a first inquiry signal from an originating mobile switching center by identifying itself to the originating mobile switching center. The incoming call may then be trunked to the home mobile switching center and forwarded to the visited mobile switching center according to the second protocol. According to another preferred embodiment, in response to the first inquiry signal, the home mobile switching center sends a second inquiry signal to the visited mobile switching center. The first inquiry signal represents a request for an identification number identifying, in the first protocol, the visited mobile switching center. The second inquiry signal represents a request for an identification number identifying in the second protocol, visited mobile switching center. In response to the second inquiry signal, the visited mobile switching center returns a first response signal to the home mobile switching center. In response to the first response signal, the home mobile switching center sends a second response signal to the originating mobile switching center, the second response signal representing, in the first protocol, a number identifying the visited mobile switching center. The call is then directly routed from the originating mobile switching center to the visited mobile switching center.
