First Claim
1. A system for connecting a mobile emergency call to a public safety answering point, comprising:
- a processor;
a non-transitory memory; and
an application stored in the memory that, when executed by the processor,receives an emergency call from a mobile station that originated from a roaming communication service provider network, wherein the mobile station is associated with a non-dialable number allocated by a home communication service provider network, and wherein the roaming communication service provider network routes the emergency call into the home communication service provider network based on a routable number to which the emergency call is directed that references a network node in the home communication service provider network,in response to receiving the emergency call from the mobile station in the roaming communication service provider network, associates, by the home communication service provider network, a temporary dialable number to the non-dialable number, andpromotes establishing a communication link between the mobile station in the roaming communication service provider network and a public safety answering point and providing the temporary dialable number to the public safety answering point, wherein, when the public safety answering point drops the communication link with the mobile station, the public safety answering point reconnects to the mobile station by calling the temporary dialable number, and wherein the temporary dialable number routes into the home communication service provider network to a signaling node and the signaling node and the roaming communication service provider network work together to connect the public safety answering point to the mobile station.

-
receiving an emergency call from a mobile station that originated from a roaming communication service provider network, wherein the mobile station is associated with a non-dialable number allocated by a home communication service provider network, and wherein the roaming communication service provider network routes the emergency call into the home communication service provider network based on a routable number to which the emergency call is directed that references a network node in the home communication service provider network; associating, by the home communication service provider network, a temporary dialable number to the non-dialable number in response to receiving the emergency call from the mobile station in the roaming communication service provider network; establishing a communication link from the mobile station in the roaming communication service provider network to a public safety answering point; and providing the temporary dialable number to the public safety answering point, wherein, when the public safety answering point drops the communication link with the mobile station, the public safety answering point reconnects to the mobile station by calling the temporary dialable number, and wherein the temporary dialable number routes into the home communication service provider network to a signaling node and the signaling node and the roaming communication service provider network work together to connect the public safety answering point to the mobile station. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of connecting a mobile emergency call to a public safety answering point (PSAP), comprising:
-
receiving an emergency call from a mobile station that originated from a roaming communication service provider network, wherein the mobile station is associated with a non-dialable number allocated by a home communication service provider network, wherein the roaming communication service provider network routes the emergency call into the home communication service provider network based on a routable number to which the emergency call is directed that references a network node in the home communication service provider network, and wherein the emergency call includes a location cue to the location of the mobile station; based on the location cue, selecting a public safety answering point from among a plurality of public safety answering points; associating, by the home communication service provider network, a temporary dialable number to the non-dialable number; and establishing a communication link from the mobile station in the roaming communication service provider network to the selected public safety answering point and providing the temporary dialable number to the selected public safety answering point, wherein, when the selected public safety answering point drops the communication link with the mobile station, the selected public safety answering point reconnects to the mobile station by calling the temporary dialable number, and wherein the temporary dialable number routes into the home communication service provider network to a signaling node and the signaling node and the roaming communication service provider network work together to connect the selected public safety answering point to the mobile station. - View Dependent Claims (14, 15, 16, 17, 18)
