[0035] In relation to figures 1 and 2, a wireless local network 1,1' comprises several wireless IAD, EQb EQ2 devices connected to an Internet access box (in English, Integrated Access Device, IAD) via a first network Rb Rf. The first network is a wireless local network (called LAN for Local Access Network). In [Fig.l], the network 1 has a star topology and in [Fig.2], the network 1' has a multi-hop topology. These topologies are given as examples and are in no way limiting. The first network Rb Rf is illustrated in solid lines.
[0036] The IAD is, for example, connected to the Internet network (not shown) via an operator network (not shown) and the first network Ri,Ri' is in particular a Wi-Fi network. The Wi-Fi network is governed by the standards and amendments from the IEEE 802.11 working group and will not be detailed further.
[0037] EQi, EQ2 wireless equipment is for example: a Wi-Fi repeater, an STB (in English, Set Top Box or digital decoder), Smart TV, TV dongle, mobile dongle (4G or 5G), smartphone, tablet, printer, home automation equipment, etc. Such a first Rb Rf network is usually installed in homes or offices.
[0038] In relation to figures 3, 4, 5 and 6, in order to improve the management of the EQi, EQ2 equipment in a wireless local area network 2, 2', each wireless EQb EQ2 equipment is equipped with a wireless control module MCIAD, MCi, MC2. Each wireless equipment is therefore associated with a wireless control module. Here again, the networks of figures 1, 3 and 5 have a star topology while the networks of figures 2, 4 and 6 have a multi-hop topology. According to the invention, each element of the network 1', 2' is therefore configured to communicate on a first network Ri and on a second network R2 as detailed in the following.
[0039] As illustrated in [Fig.7], the IAD and the wireless EQi, EQ2 equipments comprise a communication interface II, 12 and an antenna Al, A2 which manage the first network R / .
[0040] The control module MCI AD, MCh MC2 comprises a processing unit 10 configured to supervise the equipment with which it is associated and in particular manages access to the first network. Also, each control module comprises a memory 11 for storing data.
[0041] The control modules MCIAD, MCh MC2 communicate, in particular, with each other via a second network R2, R2' different from the first network Ri,Ri'. The second network R2, R2' can exist with or without the first network RB Rf.
[0042] The control modules MCIAD, MCh MC2 are advantageously powered by the same power supply (for example 12 volts) as that of the corresponding equipment IAD, EQi, EQ2 but with very low consumption (for example 0.5 Watt). The control module is integrated into the corresponding wireless equipment IAD, EQi, EQ2 and is therefore internal to it. It may be a low-consumption electronic circuit natively integrated into the product or an extension module to which a radio antenna is connected which manages the second network R2, R2'.
[0043] The control module MCIAD, MCi, MC2 is in particular configured to cut off the power supply to the first communication interface, preferably by dialoguing with the latter, and thus cut off access to the first network, the corresponding equipment then being in standby mode; while maintaining access to the second network. In other words, the control module can put the wireless equipment with which it is associated into standby mode. A dedicated button can be provided which, once actuated, puts the wireless equipment with which it is associated into standby mode. The button can be actuated directly by a physical action or virtually remotely.
[0044] In addition, the button can, upon request, put the wireless equipment it controls into standby or wake up. The waking up of the equipment corresponds to a state in which it has access to the first network.
[0045] The second network R2 is advantageously a low-consumption network having a usage range at least equivalent to the network Rb. In any event, the second network R2, R2' has an energy consumption that can remain active on equipment in standby without significant impact on the consumption of the equipment in question, unlike the first network Ri, Ri'. The second network R2, R2' is, for example, 802.15.4, Thread, Zigbee, Z-Wave or Bluetooth Low Energy, etc. Those skilled in the art understand what a low-energy consumption network is.
[0046] Figures 3 and 4 illustrate the network in which the first Wi-Fi network is active with the second network of control modules active.
[0047] Figures 5 and 6 illustrate the network in which the first Wi-Fi network is inactive with the second network of control modules active.
[0048] Via this second network R2, in the case of figures 3, 4, 5 and 6, for a star or multi-hop topology:
[0049] - the MCIAD control module of the IAD can communicate with the module of MCid communication of a first EQh equipment
[0050] - the communication module of the IAD can communicate with the com module MC2 communication of a second EQ2 equipment,
[0051] - the communication module MCid of a first equipment EQi can communicate with the MC2 communication module of a second EQ2 device.
[0052] Via the first network in the case of figures 3 and 5, for a star topology:
[0053] - the IAD can communicate with the first EQi equipment;
[0054] - the IAD can communicate with the second EQ2 equipment;
[0055] - the first equipment EQi can communicate with the second equipment EQ2 by through the second network R2
[0056] The second network formed by the control modules is thus always active regardless of the state of the first network and provides a “lifeline” which makes it possible to manage the IAD and the wireless equipment in its ecosystem. In this way, it is always possible to control each piece of wireless equipment.
[0057] The presence of a second network formed by the control modules allows several scenarios described above. Ecosystem standby
[0058] As illustrated in [Fig.8], in a network comprising an IAD and a first EQi device and possibly a second EQ2 device, a first network for example Wi-Fi being active and a second low-consumption network being active, a supervision method makes it possible to put the entire ecosystem formed by the IAD and the wireless devices on standby (see configuration (A)). In this respect, the control module puts the IAD on standby, which has the effect of cutting off the first network. The standby by the control module is subsequent to an action on the control module via a button for example (step E1). The standby of the IAD has the effect of propagating a standby command by the second network to thus put all the wireless devices EQh EQ2 on standby, the second network being active (step E2).
[0059] Such operation makes it possible to simply propagate the standby mode and reduces the carbon footprint (configuration (B)). Awakening the ecosystem
[0060] As illustrated in [Fig.9], a method for supervising a network comprising an IAD and a first EQi device and possibly a second EQ2 device, a first network for example Wi-Fi being inactive and a second low-consumption network being active makes it possible to wake up the entire ecosystem formed by the IAD and the wireless devices (see configuration (C)).
[0061] In this respect, the IAD control module wakes up the IAD, which has the effect of activating the first network. The wake-up by the control module is subsequent to an action on the control module via a button for example (step E1 a). The wake-up of the IAD has the effect of propagating a wake-up command by the second network to wake up all the wireless equipment EQi, EQ2, the second network being active (step E2a).
[0062] Alternatively, the control module of a piece of equipment wakes up the associated piece of equipment. The wake-up by the control module is subsequent to an action on the control module via a button for example (step Ela'). The wake-up of the equipment has the effect of propagating a wake-up command by the second network to wake up all the wireless pieces of equipment EQi and the IAD, the second network being active (step E2a).
[0063] Such operation makes it possible to simply propagate the wake-up (configuration (D)). Cutting off the first network
[0064] As illustrated in [Fig. 10], a method for managing a network comprising an IAD and a first EQi device and possibly a second EQ2 device, a first network for example Wi-Fi being inactive and a second low-consumption network being active makes it possible to cut off the first network (see configuration (E)) to then cause all the devices to be put on standby with the exception of the IAD (configuration (F)).
[0065] In this respect, the IAD control module cuts off the first network from the IAD, which has the effect of deactivating the first network. This is the result of an action on the IAD control module via a button, for example (step Elb). Deactivating the first network from the IAD has the effect of ordering the standby of all wireless equipment except the IAD (step E2b).
[0066] Such operation makes it possible to optimize the network and in particular the energy consumption aspect of the network. Supervision / Momtoring
[0067] As illustrated in [Fig.l 1], a method for managing a network comprising an IAD and a first device EQi and possibly a second device EQ2, a first network for example Wi-Fi being inactive and a second low-consumption network being active, the wireless devices with the exception of the IAD are on standby (configuration (G)) allows you to monitor or track wireless equipment.
[0068] In this respect, via the second network, it is possible to recover KPI (Key Performance Indicator) type metrics (REC step). Such a metric is characteristic of the availability of the wireless equipment. In configuration (G) the wireless equipment is available and simply on standby.
[0069] In configuration (H), a piece of equipment is not available and possibly has a fault and has not returned anything, the link via the second network between the IAD and this wireless equipment is broken.
[0070] Such operation makes it possible to simply ensure the health of the ecosystem. Diagnosis
[0071] As illustrated in [Fig.12], in a network comprising an IAD and a first EQi device and possibly a second EQ2 device, the second network makes it possible to diagnose a connection failure on the first network (configuration (I)) between the IAD and a wireless device.
[0072] Thanks to the link between the IAD and this equipment, it is possible to know if it is because it has lost the connection with the first network (configuration (J)) or if it is a voluntary action of the user on this equipment (configuration (K)). It is therefore possible to determine why a piece of equipment cannot be reached by the first network.
[0073] Such operation facilitates the diagnosis of the ecosystem. Software update
[0074] As illustrated in [Fig.13], in a network comprising an IAD and a first EQi device and possibly a second EQ2 device, the second network makes it possible to manage updates to the devices.
[0075] In configuration (L), a wireless device is not connected to the IAD by the first network while another device is. The IAD downloads the update for the devices and applies it to the device to which it is connected via the first network.
[0076] In configuration (M), all equipment is in standby but the IAD downloads the update for the equipment.
[0077] According to these configurations (L) and (M) it is thanks to the second network that the IAD was able to determine that the wireless equipment is indeed in its ecosystem.
[0078] In this scenario, as soon as the connection to the first network is reestablished for each device, then the updates are applied (configuration (N)).
[0079] Such operation makes it possible to retrieve updates without worrying about the state of the equipment with respect to the first network.
