Method and network for emergency call services
First Claim
1. A method of managing an Emergency Services Call (ESC) within a mobile network while a subscriber is engaged in an on-going call, wherein the network includes a serving entity, an anchor entity, a Position Determination Entity (PDE), and an Emergency Services Entity (ESE), the method comprising the steps of:
- handing off the on-going call from the anchor entity to the serving entity;
responsive to an emergency condition, the subscriber invoking the ESC via 3-way calling while maintaining the on-going call;
receiving a request for the ESC at the serving entity;
receiving a request for a current geographic position of the subscriber at the PDE;
determining the current geographic position of the subscriber by the PDE;
receiving the current geographic position of the subscriber at the serving entity;
sending the current geographic position to the anchor entity;
setting up the ESC between the anchor entity and the ESE, wherein the current geographic position is included in the call setup message; and
updating the anchor entity with the current geographic position.

Abstract
A method and network provide mobile information for emergency calls based on mobile position during a call in progress. As soon as an Emergency Services Call is invoked, the Mobile Station position information is gathered using a Serving Entity. The position is then sent to an Anchor Entity [typically an Anchor Mobile Switching Center (AMSC) and Anchor Mobile Position Center (AMPC)] in communication with the Emergency Services Network Entity (ESNE). After receiving the position information, the Anchor Entity makes the call setup to the ESNE, and the AMSC updates the AMPC.
In one alternative embodiment, the Position Determining Entity determines the troubled and non-troubled locations and sends them to the ESNE. In a second alternative embodiment, only the troubled party location is sent to the ESNE as a result of the non-troubled party triggering a special key code during the request for the ESNE.

8. A mobile network for managing an Emergency Services Call (ESC) invoked by a subscriber while the subscriber is engaged in an on-going call that has been handed off from the anchor entity to the serving entity to serve the subscriber at a current location, comprising:
-
an Anchor Entity for updating the current location prior to setting up the ESC; a Serving Entity in electronic communication with the Anchor Entity for maintaining the on-going call; a Position Determining Entity (PDE) in electronic communication with the Serving Entity;
for determining the current geographic position of the subscriber;an Emergency Services Entity (ESE) in electronic communication with the Anchor Entity; and a 3-way calling function enabling the initiation of the ESC to the ESE while maintaining the on-going call. - View Dependent Claims (9, 10, 11)

12. A method of managing an Emergency Services Call (ESC) within a mobile network while a non-troubled subscriber is engaged in an on-going call with a troubled subscriber at a troubled location, wherein the network includes a serving entity, an anchor entity, a Position Determination Entity (PDE), and an Emergency Services Entity (ESE), the method comprising the steps of:
-
handing off the on-going call from the anchor entity to the serving entity; responsive to an emergency condition, the subscriber invoking the ESC via 3-way calling while maintaining the on-going call receiving a request for the ESC at the serving entity; receiving a request for the troubled location of the troubled subscriber at the PDE; determining the troubled geographic position of the troubled subscriber by the PDE; receiving the troubled geographic position of the troubled subscriber at the serving entity; sending the troubled geographic position to the anchor entity; and setting up the ESC between the anchor entity and the ESE. - View Dependent Claims (13)
