Abstract

A method for call routing for emergency network connectivity, comprising A method for call routing for emergency network connectivity, comprising: utilizing a public communications network, establishing a trigger connection from a service management system to a mobile switching center serving a mobile unit; and using the trigger connection, triggering an emergency 911 connection from the mobile switching center to a public safety answering point serving the mobile unit based upon a unit position data of the mobile unit.

Claims

1. A system for routing a call to an answering point comprising:

a mobile unit capable of initiating a call and transferring position data with the call;

a call center receiving the call and the position data; and

a network coupling the call center to a mobile switching center serving the mobile unit,

wherein position data is transferred from the mobile unit to the call center and, upon a connection from the call center to the mobile switching center, from the call center to the mobile switching center, and

wherein the mobile switching center utilizes the position data to connect to an answering point associated with a location of the mobile unit.

2. The system of claim 1, wherein the first mobile switching center serving the mobile unit is selected based on the unit position data.

3. The system of claim 1, wherein the position data is utilized by another mobile switching center to identify the mobile switching center.

4. The system of claim 1, wherein the mobile unit is further capable of transferring additional data relating to the mobile unit.

5. The system of claim 1, wherein the mobile unit is capable of voice communications with the answering point.
