VIDEO SURVEILLANCE SYSTEM USING MOBILE TERMINALS
First Claim
1. A method for operating a video surveillance system able to monitor a set of surveillance zones by a set of cameras, comprising the following steps in an application server in a telecommunication network able to communicate with the video surveillance system:
- for each mobile terminal that has established an emergency call with an emergency call center and whose user is witness of an incident, retrieving localization data associated with the mobile terminal,determining ES if the mobile terminal is located in a surveillance zone, using the retrieved localization data,receiving ES a message sent from the mobile terminal, the message containing current localization data of the mobile terminal and a direction from the mobile terminal towards the incident,if at least two mobile terminals are located in a same surveillance zone, computing ES coordinates EC of the incident, taking into account said current localization data and said directions provided by said at least two mobile terminals, andsending an incident message containing the coordinates of the incident to the video surveillance system that is able to select at least one camera using the coordinates of the incident.

Abstract
A video surveillance system able to monitor a set of surveillance zones by a set of cameras is disclosed. The video surveillance system includes an application server in a telecommunication network able to communicate with the video surveillance system to retrieve localization data associated with each mobile terminal that has contacted an emergency call center and whose user is witness of an incident, receive a message sent from the mobile terminal, the message containing current localization data and a direction towards the incident, if more than one call about an incident is received, compute coordinates of the incident, taking into account said current localization data and said directions provided by the at least two mobile terminals, then finally, send an incident message containing the coordinates of the incident to the video surveillance system that is able to select at least one camera using the coordinates of the incident.

11. An application server in a telecommunication network for operating a video surveillance system able to monitor a set of surveillance zones by a set of cameras, the application server being able to communicate with the video surveillance system and comprising:
-
means for retrieving localization data, for each mobile terminal that has established an emergency call with an emergency call center and whose user is witness of an incident, associated with the mobile terminal, means for determining if the mobile terminal is located in a surveillance zone, using the retrieved localization data, means for receiving a message sent from the mobile terminal, the message containing current localization data of the mobile terminal and a direction from the mobile terminal towards the incident, means for computing coordinates of the incident, taking into account said current localization data and said directions provided by at least two mobile terminals, if said at least two mobile terminals are located in a same surveillance zone, means for sending an incident message containing the coordinates of the incident to the video surveillance system that is able to select at least one camera using the coordinates of the incident.

12. A computer program adapted to be executed in an application server in a telecommunication network for operating a video surveillance system able to monitor a set of surveillance zones by a set of cameras, the application server being able to communicate with the video surveillance system, said program including instructions which, when said program is executed in said presence server, execute the following steps:
-
for each mobile terminal that has established an emergency call with an emergency call center and whose user is witness of an incident, retrieving localization data associated with the mobile terminal, determining if the mobile terminal is located in a surveillance zone, using the retrieved localization data, receiving a message sent from the mobile terminal, the message containing current localization data of the mobile terminal and a direction from the mobile terminal towards the incident, if at least two mobile terminals are located in a same surveillance zone, computing coordinates of the incident, taking into account said current localization data and said directions provided by said at least two mobile terminals, sending an incident message containing the coordinates of the incident to the video surveillance system that is able to select at least one camera using the coordinates of the incident.
