System, method, and computer program product for connectivity of wireless base station to PSTN via an IP data network

A method of providing wireline telephony services to packet data network protocol telephony subscribers, the method comprising:

• managing the subscriber's wireless mobility services for a packet data network call, the managing comprising:
• sending a termination message to a control node on the packet data network;
• and
• determining a service wireless base station controller;
• and
• mapping the packet data network protocol information pertaining to the packet data network call to an end office access protocol,
• such that the packet data network call can utilize all of the wireline services associated with an end office switching network wherein managing the mobility services includes call delivery managing, the call delivery managing comprising:
• mapping termination messages from the access control protocol used by an end office telephony switch to a call control protocol used by the packet data network;
• sending the termination messages to a control node on the data network;
• determining a service wireless base station controller;
• sending a routing request message to a serving switch if the serving base station controller is not on the packet data network;
• providing a directory number to be used to deliver the call to the serving switch through the public switching telephone network (PSTN);
• formulating, in the call control node of the packet data network, a re-directing call control message to the gateway associated with the end office telephony switch that initiated the termination;
• formulating, in the gateway associated with the end office telephony switch that initiated the termination, a re-directing call control message using the access control protocol;
• and
• re-directing the call through the public switching telephone network (PSTN) using the directory number supplied by the gateway.

A system for providing end office wireless telephony services to wireless telephony subscribers using a packet data network, the system comprising:

• means for mapping a subscriber's wireless telephony protocol to a packet data network protocol;
• means for managing the subscriber's wireless mobility services for a wireless call, the means for managing comprising means for sending call origination messages to a control node on the packet data network;
• and
• means for mapping the packet data network protocol information pertaining to the wireless call to an end office access protocol;
• such that the wireless call can utilize all of the wireline services associated with an end office telephony switching network wherein the means for managing mobility services includes means for call delivery managing, the means for call delivery managing comprising:
• means for mapping termination messages from the access control protocol used by an end office telephony switch to a call control protocol used by the packet data network;
• means for sending the termination messages to a control node on the data network;
• means for determining a serving wireless base station controller;
• means for sending a routing request message to a serving switch if the serving base station controller is not on the packet data network;
• means for providing a directory number to be used to deliver the call to the serving switch through the public switching telephone network (PSTN);
• means for formulating in the call control node of the packet data network, a re-directing call control message to the gateway associated with the end office telephony switch that initiated the termination;
• means for formulating, in the gateway associated with the end office telephony switch that initiated the termination, a re-directing call control message using the end office access control protocol;
• and
• means for re-directing the call through the public switching telephone network (PSTN) using the directory number supplied by the gateway.

The system of claim 29 wherein the means for managing mobility services includes means for inter-system handoff managing of a call from a current cell area having a base station controller gateway with an established media channel to a target cell area, the means for inter-system handoff managing comprising the steps of:

• means for maintaining a timer that will allow sufficient time for a mobile subscriber to tune from the current cell area to the target cell area;
• means for constructing and sending a facilities directive message to a target mobile switching center gateway;
• means for establishing a media channel with the target mobile switching center gateway;
• and
• means for simulcasting all speech to the current base station controller gateway media channel and the target mobile switching center gateway media channel until the timer expires, upon which the current base station controller gateway channel will cease transmitting and receiving such that only the target mobile switching center gateway media channel is transmitting and receiving.
