A third party tandem provider that intercepts and routes voice and data traffic between telecommunications carriers, e.g., wireless carriers, local exchange carriers, and long distance carriers, by dynamically determining the actual terminating switch for a call using a plurality of proprietary data
A third party tandem provider that intercepts and routes voice and data traffic between telecommunications carriers, e.g., wireless carriers, local exchange carriers, and long distance carriers, by dynamically determining the actual terminating switch for a call using a plurality of proprietary databases versus terminating calls merely based on the switch associated with the terminating telephone number. The tandem services provider Service Control Point (SCP) is arranged to maintain a carrier unit's status in a resident database or secure such information per call from the terminating carrier's database. When a call is placed to a telephone number associated with a carrier connected to the tandem, the tandem platform Service Switching Point (SSP) queries the SCP for availability and routing instructions. In response, the SCP accesses its database and/or the terminating carrier's database to determine the status of the unit. If the unit is available, the SCP sends the SSP the unit's current service address (e.g., IP address, telephone number, location routing number) to route the call to the switching location currently serving the subscriber unit. If the unit is unavailable, the SCP sends the SSP the information to route the call to the home switch associated with the called unit for announcement, voice mail, or other treatment. The terminating carrier thus avoids the internal routing inefficiencies of re-directing the call within its network.

1. In a third party tandem services network interconnecting a plurality of wireline and wireless carriers, a system for selectively directing a call originating from one of the plurality of carriers to a terminating switch presently serving a called subscriber unit of another of the plurality of carriers, said system comprising: a subscriber unit location register database maintained by at least one of the plurality of carriers connected to the third party tandem services network, the subscriber unit location register database containing information indicative of each subscriber unit's registration status and location for the at least one of the plurality of carriers; anda service control point (“SCP”) in communication with the subscriber unit location register database and including an SCP database of data indicative of an availability status of the called subscriber unit,wherein the subscriber unit location register database provides data representative of the registration status and location of the called subscriber unit, including one of either a routing destination number and an equivalent telephone number, to the SCP for updating of the SCP database;wherein the SCP is arranged to access the SCP database directly when a request for call-routing information is received from a third party tandem services network switch and to provide the call-routing information to the third party tandem services network switch;wherein if the SCP determines that the called subscriber unit is available, the SCP sends a third party tandem services network switch service switching point (“SSP”) the called subscriber unit's current service address to route the call to the terminating switch presently serving the called subscriber unit; andwherein if the SCP determines that the called subscriber unit is unavailable, the SCP sends a third party tandem services network switch service switching point (“SSP”) the information to route the call to a home switch of the another of the plurality of carriers for at least one of an location register database announcement, a voice mail, and another call treatment. 2. In a third party tandem services network interconnecting a plurality of wireline and wireless carriers, a system for selectively directing calls originating from one of the plurality of carriers to a terminating switch presently serving a called subscriber unit of another of the plurality of carriers, said system comprising: a subscriber unit location register database containing information indicative of a registration status and location for each of a plurality of subscriber units for one of the plurality of carriers; anda service control point (“SCP”) in communication with the subscriber unit location register database and including an SCP database of data indicative of an availability status of the called subscriber unit,wherein the SCP is arranged to access the SCP database directly when a request for call routing information is received from a third party tandem services network switch and to provide the call routing information to the third party tandem services network switch;wherein if the SCP determines that the called subscriber unit is available, the SCP sends a third party tandem services network switch service switching point (“SSP”) the called subscriber unit's current service address to route the call to the terminating switch presently serving the called subscriber unit; andwherein if the SCP determines that the called-subscriber unit is unavailable, the SCP sends a third party tandem services network switch service switching point (“SSP”) the information to route the call to a home switch of the another of the plurality of carriers for at least one of an announcement, a voice mail, and another call treatment.
