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.

Abstract: The invention pertains to a method for providing an observer with data related to at least one user of a telecommunication or Internet services operator within a network, said method providing that said observer send a request to said operator to obtain data in response to said request, said method comprising analyzing the data requested by said observer in response to said request, automatically constructing a new request based on said analysis, and using said new request so that said operator transmits to said observer new data in response to said new request.

Abstract: A lawful interception architecture for an operator of communication networks (NWO) comprising sets of interception probes (SON1-SONN) respectively deployed in telecommunication networks (RT1-RNN) in order to provide envelope data (DonE) and content data (DonC) regarding communications passing through at east one of the telecommunication networks, comprising an adaptation system (SA) which receives envelope data and content data provided by at least one set of interception probes (SONn), and converts the envelope data into formatted envelope data (DonF) of a single predetermined format. The system associates this formatted envelope data and this content data with one another, the formatted envelope data containing a single identifier (IDC) for the associated content data and being saved within a data saving device (DRD) connected to the system.

Abstract: The invention concerns a router associated to a secure device (DC) and included in a communication network (RC), comprising an interface (IRT) to communicate with the secure device following an authentication of the router by the secure device, and comprising a protocol interpreter (INT) to command the execution of the critical operations of one or more routing protocols by the secure device. The sensitive or critical portions of a routing protocol are executed in a secure and reliable manner in the secured device, for example of a chip card type.

Abstract: To monitor the functioning of the services of a first infrastructure (CI1) upon which the functioning of the critical services of a second infrastructure (CI2) depend, a server (SS) capable of communicating with both infrastructures receives, upon the detection of a failure of a service of the first infrastructure by a first terminal (CT1) included within the first infrastructure, an identifier (SI) for the faulty service sent from the first terminal. The server transmits a request to the first terminal in order to retrieve the characteristics settings values of the faulty service, and apply correlation rules to the retrieved values in order to produce information relevant to the functioning of the faulty service. The server transmits a message (SPM) containing the produced information to a second terminal (CT2) included within the second infrastructure, so that the second infrastructure can react to the failure of a service of the first infrastructure.

Abstract: Method for classification of traffic on telecommunications networks, said method including a stage for the capture of traffic and a stage for detailed packet analysis, said method also including a stage for the statistical classification of traffic using a statistically-generated decision tree.
