Abstract

A method for an enhanced initiation and/or routing of an emergency session in a packet switched communication system includes: determining or defining—by a mobile communication device or by means of the mobile communication device—of personal communication ability information and/or personal medical condition information of a user of the mobile communication device; and initiating the emergency session by using the mobile communication device. Initiating the emergency session comprises transmitting an emergency message, via a packet switched connection of the mobile communication device, to the packet switched communication system. The personal communication ability information and/or the personal medical condition information is part of the emergency message.

First claim

The invention claimed is:

1. A method for initiation and routing of an emergency session in a packet switched communication system, wherein a public safety answering point is able to be accessed by the packet switched communication system, wherein the emergency session comprises a voice call or a video call, and wherein the method comprises:
determining or defining, by a mobile communication device in or connected to the packet switched communication system, personal language preference information and/or personal medical condition information of a user of the mobile communication device;
initiating, by the mobile communication device, the emergency session, wherein initiating the emergency session comprises the mobile communication device transmitting an emergency message, via a packet switched connection of the mobile communication device, to the packet switched communication system, and wherein the personal language preference information and/or the personal medical condition information is part of the emergency message;
evaluating, by a network entity of the packet switched communication system, the personal language preference information and/or the personal medical condition information of the emergency message;
selecting, by the network entity of the packet switched communication system, a respective public safety answering point or an instance of a respective public safety answering point in accordance with the evaluated personal language preference information and/or the evaluated personal medical condition information; and
sending, by the network entity of the packet switched communication system, the emergency message to the selected public answering point or the selected instance to establish the emergency session,
wherein the personal language preference information comprises at least one out of the following:
an indication of a preferred language to be used by the public safety answering point during the voice call or the video call, or
an indication of a prioritized list of preferred languages to be used by the public safety answering point during the voice call or the video call;

wherein the personal medical condition information comprises at least one out of the following:
an indication of a preferred additional contact person or contact instance to be used or contacted by the public safety answering point,
an indication of a prioritized list of preferred additional contact persons or contact instances to be used by the public safety answering point, or
an indication of reference information to a medical or personal record of the user of the mobile communication device.

2. The method according to claim 1 , wherein the emergency session is an IP multimedia subsystem (IMS)-based packet switched emergency session;
wherein the personal language preference information and/or the personal medical condition information is:
part of a session initiation protocol (SIP) invite message,
part of SIP header information of the emergency message, and/or
part of an extended markup language (XML) body of the emergency message.

3. The method according to claim 1 , wherein the method further comprises:
analyzing personal language preference data,
determining a sequence of communication channels based on the analysis,
arranging the personal language preference information in accordance with the determined sequence, and routing the emergency message based on the determined sequence and availability of corresponding recipients, either in network nodes of an IP multimedia subsystem (IMS) core or in the public safety answering point, wherein the network nodes of the IMS core include a P-call state control function (P-CSCF) node, an E-call state control function (E-CSCF) node, and/or an application server (AS) node.

4. The method according to claim 1 , wherein the method further comprises:
prior to initiating the emergency session by the mobile communication device, detecting an emergency situation via the mobile communication device or a device coupled with the mobile communication device.

5. The method according to claim 1 , wherein determining or defining the personal language preference information and/or the personal medical condition information of the user of the mobile communication device comprises determining or defining the personal language preference information of the user of the mobile communication device;
wherein determining or defining the personal language preference information of the user of the mobile communication device comprises: reading out language preference data of a memory device of the mobile communication device or a device coupled to the mobile communication device.

6. The method according to claim 1 , wherein determining or defining the personal language preference information and/or the personal medical condition information of the user of the mobile communication device comprises determining or defining the personal medical condition information of the user of the mobile communication device;
wherein determining or defining the personal medical condition information of the user of the mobile communication device comprises: reading out personal health data of a memory device of the mobile communication device or a device coupled to the mobile communication device.

7. The method according to claim 1 , wherein:
a recipient of the public safety answering point is an automatic translator, enabling a connection with any public safety answering point,
the public safety answering point uses voice-to-text translation, and/or
a translation of the public safety answering point is selected based on a quality of the translation in a respective language.

8. The method according to claim 1 , wherein sending the emergency message to the selected public answering point or the selected instance is further based on an emergency call type corresponding to the emergency message.

9. The method according to claim 1 , wherein sending the emergency message to the selected public answering point or the selected instance is further based on a called number corresponding to the emergency message.

10. The method according to claim 1 , wherein the emergency message is enriched with network-based information prior to being sent to the selected public answering point or the selected instance, wherein the network-based information includes a cell ID.

11. The method according to claim 1 , wherein the emergency message is enriched with network-based information prior to being sent to the selected public answering point or the selected instance, wherein the network-based information includes a map.

12. The method according to claim 1 , wherein the emergency message is enriched with network-based information prior to being sent to the selected public answering point or the selected instance, wherein the network-based information includes weather information.

13. The method according to claim 1 , wherein the emergency message is enriched with network-based information prior to being sent to the selected public answering point or the selected instance, wherein the network-based information includes news information.

14. The method according to claim 1 , wherein the emergency message is enriched with network-based information prior to being sent to the selected public answering point or the selected instance, wherein the network-based information includes blog information.

15. The method according to claim 1 , further comprising:
adding a parallel session leg to the emergency session such that multiple different public safety answering points are conferenced as part of the emergency session.
