System and method for reducing the energy consumption of an interconnection device
First Claim
1. A method used by a device for interconnecting a first communication network and a second communication network, said interconnection device comprising a plurality of components functioning in an active mode or a standby mode, wherein said interconnection device performs the following steps:
- changing to active mode the plurality of components under control of a secondary processor, the secondary processor being a component of the interconnection device continuously in active mode and controlling changes to active mode of the plurality of components at given instants, the given instants being controlled by the secondary processor using a control parameter fixed by the interconnection device when the plurality of components are in active mode, where the control parameter is a function of statistics of a quantity of services implemented by the interconnection device, a change to standby mode being controlled by the interconnection device following an end of use of a service,following the change of the plurality of components to active mode, sending an interrogation request to a service-management server connected to the first communication network in order to check the existence of service demands,receiving a response to the interrogation request, andchanging the plurality of components to standby mode by means of the secondary processor at an instant dependent on the response received.

Abstract
A device for interconnecting a first communication network and a second communication network comprises a plurality of components functioning in an active mode or a standby mode. Said interconnection device performs the following steps: changing to active mode (401) the plurality of components under the control of a secondary processor, the secondary processor being a component of the interconnection device continuously in active mode and controlling changes to active mode following the change to active mode, sending (405) an interrogation request to a service-management server (110) connected to the first communication network in order to check the existence of service demands, receiving (407) a response to the interrogation request; and changing the plurality of components to standby mode (427) at an instant dependent on the response received.

6. A method implemented by a service-management server connected to a first communication network, the first communication network being connected to a second communication network by an interconnection device, wherein, in the event of reception of an interrogation request coming from the interconnection device, the service-management server performs the following steps:
-
checking the presence of a service implementation demand emanating from a remote item of equipment in a list of service implementation demands, each service implementation demand requesting execution of a service by the interconnection device, if a service implementation demand is present, sending a response to the interconnection device containing information representing the service implementation demand received, said interrogation requests having been sent by the interconnection device at a given period wherein the interconnection device was functioning in active mode, the each transition from standby mode to active mode being controlled by a secondary processor of the interconnection device, and the service-management server controlling the given period when the interconnection device goes into active mode by determining modification information intended to modify a control parameter of the secondary processor of the interconnection device allowing control of said period and by sending said modification information to the interconnection device to modify said control parameter, said modification information being determined by the service-management server as a function of statistics on a frequency of reception of service implementation demands by the service-management server. - View Dependent Claims (7, 8, 12)

9. A service-management server connected to a first communication network, the first communication network being connected to a second communication network by an interconnection device, wherein the device is configured for:
-
receiving interrogation requests coming from the interconnection device, said interrogation requests having been sent at determined periods corresponding to changes of the interconnection device from standby mode to active mode controlled by a secondary processor of the interconnection device, the service-management server controlling the period when the interconnection device goes into active mode by determining modification information intended to modify a control parameter of the secondary processor of the interconnection device to allow control of said period and by sending said modification information to the interconnection device to modify said control parameter, said modification information being determined by the service-management server as a function of statistics on a frequency of reception of service implementation demands by the service-management server; and checking, in the case of reception of an interrogation request, the presence of a service implementation demand coming from remote equipment in a list of service implementation demands, and sending a response to the interconnection device containing information representing a service implementation demand received if a service implementation demand is present.

10. An interconnection device for interconnecting a first network and a second network, comprising a plurality of components functioning in an active mode or a standby mode, wherein the device comprises:
-
a secondary processor, continuously in active mode, configured to control changes of the plurality of components to active mode at given instants, the given instants being controlled by the secondary processor using a control parameter fixed by the interconnection device when the plurality of components are in active mode as a function of statistics on a quantity of services implemented by the interconnection device; and the device is configured for sending, following a change of the plurality of components to active mode, an interrogation request to a service-management server, receiving a response to the interrogation request, and determining an instant of changing to standby mode according to the response received.
