Abstract: A technique for remote administration of a device to be administered. A relay device receives a request to activate a filter for administration of the device to be administered from a referring administration server. This activation request includes information relating to rights assigned to a third-party administration server for delegating the administration of the device to be administered. The relay device then applies a filter to a message received from the third-party administration server intended for the device to be administered, the message received from the third-party administration server being filtered by the filter when it does not comply with the rights assigned to the third-party administration server.

Abstract: An alert device and method are described. The method is implemented in an electronic device and includes receiving, over at least one time window, of a plurality of content access requests, and generating an alert as a function of at least one frequency of change of a content category between contents associated with at least two of said requests and/or of the time elapsed between two of said requests.

Abstract: A method for coordinating a plurality of device management servers, the plurality of device management servers including at least a first management server and a second management server. The method includes: receiving a first instruction for a first device connected to the first management server; receiving a second instruction for a second device connected to the second management server; obtaining information concerning dependency between the first and second devices; based on the dependency information and rules for coordinating the execution, determining an order of execution of the first instruction and second instruction; generating and sending a first control signal for executing the first instruction and a second control signal for executing the second instruction according to the determined order.

Abstract: Remote administering a device by an administration server. A management operation is to be executed by the administration server on the device. A piece of information on state of use of the device is then obtained and an execution impact of the management operation is evaluated for a quality of service for a service supplied by the device, depending on the piece of information obtained and the management operation to be executed. A postponement of the execution of the management operation is requested from the administration server. This postponement is determined according to the piece of information obtained, that impact and a policy for executing management operation defining an association between a state of use of a device, an operation and an impact.
