Abstract

Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by a device a triggering message from an emergency call server responsive to an indication of an emergency condition at the device to trigger a tracking session to periodically collect and send tracking session data associated with the device to one or more servers, establishing the tracking session, separate from an emergency call session established between the device and the emergency call server, with the one or more servers, and sending, by the device to the one or more servers, the tracking session data collected during the tracking session by the device.

First claim

What is claimed is:

1. A method comprising:
establishing an emergency call session between a device and an emergency call server;
receiving, in the emergency call session by the device from the emergency call server, a request for location information for the device;
sending, in the emergency call session, the location information by the device to the emergency call server;
receiving, in the emergency call session by the device, a triggering message from the emergency call server to trigger a tracking session to collect and send tracking session data of the tracking session to one or more tracking servers;
establishing the tracking session, independent from the emergency call session established between the device and the emergency call server, by the device with the one or more tracking servers, wherein continuance of the tracking session is independent of continuance of the emergency call session; and
sending, in the tracking session by the device to the one or more tracking servers, the tracking session data collected during the tracking session by the device.

2. The method of claim 1 , further comprising one of:
sending by the device to the emergency call server the indication of the emergency condition; or
sending, in response to a broadcast message transmitted by the emergency call server, a reply message from the device, the reply message comprising the indication of the emergency condition.

3. The method of claim 1 , wherein receiving by the device the triggering message from the emergency call server comprises:
receiving a mandatory tracking session command, in response to a determination that the device is to be tracked, to cause the device to establish the tracking session, wherein the mandatory tracking session command cannot be overridden by the device or by a user of the device.

4. The method of claim 1 , further comprising:
in response to receiving the triggering message to establish the tracking session, placing the device in a reduced-power tracking mode state, including:
reducing power provided to sub-systems of the device not required to collect or communicate the tracking session data associated with the device; and
providing at least partial power to one or more sensor or communication sub-systems of the device to cause the one or more sensor or communication sub-systems to operate at least partially while the device is in the reduced-power tracking mode state to collect and communicate to the one or more servers at least some of the tracking session data.

5. The method of claim 1 , wherein sending the indication of the emergency condition comprises:
sending a message to the emergency call server comprising an emergency type indication, data representative of device capabilities of the device, or location-based data, or any combination thereof.

6. The method of claim 5 , wherein the data representative of the device capabilities of the device comprises: communication protocols supported by the device, types of transceivers included with the device, types of sensors included with the device, or battery level of the device, or any combination thereof.

7. The method of claim 5 , wherein the location-based data comprises: a computed approximation of a location of the device, timing measurements measured by the device, or signal strength measurements measured by the device, or any combination thereof.

8. The method of claim 1 , further comprising:
terminating the tracking session in response to: a user indication received from a user of the device, or a termination message from at least one of the one or more servers, or any combination thereof.

9. The method of claim 1 , wherein sending the tracking session data comprises:
determining at a first time instance one or more subsequent wake-up times to transmit data to the one or more tracking servers.

10. The method of claim 9 , wherein determining the one or more subsequent wake-up times comprises:
determining one or more subsequent adjustable periodic wake-up times to transmit the tracking session data to the one or more tracking servers based on: charge level of a battery of the device, time elapsed since the indication of the emergency condition was communicated, connectivity bandwidth, or a maximum periodicity for communicating by the device the tracking session data, or any combination thereof.

11. The method of claim 1 , further comprising:
configuring the device to prevent deactivation of one or more sensor and communication sub-systems of the device required for collection and communication of the tracking session data even if the device is turned off by a user.

12. The method of claim 1 , wherein the collected tracking session data comprises:
sensor data collected by one or more sensors disposed in the device, or disposed proximate to the device, or a combination thereof, the one or more sensors comprising: one or more inertial sensors, a thermometer, a barometer, an optical sensor, a humidity sensor, an ambient light sensor, or one or more biometric sensors, one or more vehicle sensors for a vehicle disposed proximate to the device, or any combination thereof.

13. The method of claim 1 , wherein the location information comprises:
location-based data, access point information, Bluetooth low energy (BTLE) information, ranging information, or identification information corresponding to the device, or any combination thereof.

14. The method of claim 1 , wherein sending the indication of the emergency condition comprises:
communicating from the device to the emergency call server: a long-term evolution positioning protocol (LPP) message, a session initiation protocol (SIP) message, a universal mobile telecommunication system (UMTS) message, or a secured hypertext transfer protocol (HTTPS) message, or any combination thereof.

15. The method of claim 1 , wherein establishing the tracking session with the one or more servers comprises:
establishing one or more communication links with the one or more servers according to identifiers for the one or more servers received from the emergency call server.

16. A wireless device comprising:
a transceiver configured to:
receive, in an emergency call session, a request for location information from an emergency call server;
receive, in the emergency call session, a triggering message from the emergency call server to trigger a tracking session to collect and send tracking session data of the tracking session to one or more tracking servers; and

one or more processors, coupled to the transceiver, configured to:
establish the emergency call session between the wireless device and the emergency call server;
establish the tracking session, independent from an emergency call session established between the wireless device and the emergency call server, with the one or more tracking servers, wherein continuance of the tracking session is independent of continuance of the emergency call session; and
determine the location information;

wherein the transceiver is further configured to send, in the tracking session, to the one or more tracking servers, the tracking session data collected during the tracking session by the wireless device and the location information to the emergency call server.

17. The wireless device of claim 16 , wherein the transceiver is further configured to:
send to the emergency call server the indication of the emergency condition; or
send, in response to a broadcast message transmitted by the emergency call server, a reply message, the reply message comprising the indication of the emergency condition.
