Description Title of the invention: Methods and devices for transmitting and receiving a radiobeacon signal to establish communication between two terminals. [pool j I.

Field of the invention

The invention relates to the establishment of a communication between two items of equipment.

More particularly, the invention relates to the transmission of connection information via a radio beacon or Beacon signal in English.

[0003] 2.

Prior Art

[0004] In his home environment, a user now has more and more electronic equipment (computer, multimedia) capable of interacting with one another to provide services to the user.

In particular, most of the connected equipment is supplied with a website or a mobile application intended to be installed on a mobile terminal, for example a Smartphone (for smart phone in English) or a tablet.

Such a website or such a mobile application is dedicated to the equipment with which it was supplied and makes it possible in particular to configure, control, troubleshoot the equipment and / or enhance the service provided by the equipment.

[0005] A major drawback is that each connected device is provided with its own website and / or its own mobile application.

Thus, the more the number of connected devices of a user increases, the more the number of websites or mobile applications to be installed on the user's mobile terminal increases.

This is problematic because the user must then manage this multiplicity of tools and install a large number of mobile applications.

In addition, this also has an impact on the resources of the mobile terminal, in particular its memory.

[0006] In order to allow the exchange of data between the mobile terminal and the connected device, the two devices must establish a two-way communication link (for example in WiFi or in Bluetooth).

In other words, a preliminary configuration step is necessary.

Such a preliminary configuration step allows the mobile terminal and the connected equipment item to exchange information concerning the communication mode to be used, an identifier of each of the equipment items, their respective capacities, etc.

[0007] For example, in the case of communication between a mobile terminal and a Bluetooth device, it is necessary for the user of the mobile terminal to select, via an interface of his mobile terminal, the device with which he wishes associate his mobile terminal.

Often, the list of Bluetooth devices is 2 long (it depends on the number of user devices that are Bluetooth compatible and nearby) and the names of the devices in this list are rarely intuitive to the user.

For example, it is often a generic name determined by the manufacturer for a type of device.

The user may have difficulty in easily and quickly identifying the equipment to be paired with his mobile terminal.

This problem also arises in the case of a WiFi communication protocol.

Indeed, according to this communication protocol, the list of available connection points can be long and the identifiers of these WiFi access points not very explicit.

[0009] There is therefore a need to improve the state of the art.

[0010] 3.

Disclosure of the invention

The invention improves the state of the art.

For this purpose, it relates to a method of transmitting a signal comprising connection data allowing the establishment of a communication between a sending device and a mobile terminal, the method being implemented by the sending device.

Advantageously, such a transmission method comprises:

- the detection, by the sending device, of a trigger signal for sending connection data,

- following the detection of the trigger signal, the generation of said signal, said signal being a radio beacon signal according to a "Bluctooth Law Encrgy" specification, comprising said connection data, in a tag identification field of said signal radio beacon,

- transmitting said radio beacon signal.

Correspondingly, the invention also relates to a method for receiving a signal comprising connection data allowing the establishment of a communication between a sending device and a mobile terminal, the reception method being implemented by said mobile terminal.

Advantageously, the reception method comprises:

- reception of a radio beacon signal according to a "Bluetooth Low Energy" specification,

- waking up an application installed on the mobile terminal associated with said radio beacon signal,

[0018] obtaining said connection data from said radiobeacon signal, said connection data being included in a beacon identification field of said radiobeacon signal,

[0019] sending to said sender device a request to set up a communication using connection data.

The invention thus allows the establishment of a communication between a mobile terminal and a transmitter device in a simple and automatic manner.

The mobile terminal no longer has to know in advance the sending device with which it wishes to establish a communication.

Indeed, the user no longer has to select an item of equipment with which he wishes to connect his mobile terminal.

This connection is implemented automatically as soon as a trigger signal is detected by the sending device.

For example, such a trigger signal can be an interaction of the user on the equipment with which he wishes to connect his mobile terminal, or else a timer expiry, for example in the case of machine-to-machine communication.

The trigger signal can also correspond to the reception of a signal: for example the reception of an NFC signal when the mobile terminal is approached to the sending device, or any other type of signal, for example via a remote control.

By transmitter device is meant here any electronic equipment capable of establishing communication with a mobile terminal.

For example, it can be a speaker, a voice assistant, a home gateway, a TV decoder, a WiFi repeater, etc.

To trigger the connection between the mobile terminal and the sender device, the user interacts on the sender device.

For example, such an interaction can be a press on a dedicated button of the sending device, or else on a button coupled to other functions of the sending device.

Advantageously, the invention uses the radiobeacon mechanism of the Bluetooth LE specification, also known under the name Beacon in English, to transmit the connection data making it possible to establish a communication between the mobile terminal and the sending device.

In known manner, a Beacon BLE signal makes it possible to transmit a small quantity of data at regular time intervals by a beacon and comprising a beacon identifier.

Such a signal is often used to allow a location of a user inside buildings in which the reception of a GPS signal is not sufficiently good and / or to allow sending information / advertisements to a user on his mobile terminal when the mobile terminal is near the beacon, via a dedicated application installed on the mobile terminal and identified by the identifier of the beacon.

Thus, according to the prior art, the Beacon signal makes it possible to wake up a mobile application capable of managing the type of the beacon that sent the Beacon signal and of receiving, via this mobile application, information coming from a remote server, as a function of the identifier associated with this tag.

According to the prior art, the device which emits a Beacon signal is a low-capacity device intended to transmit a small amount of data over a short distance (of the order of 20 cm to 30 m) so as to consume little energy. .

According to the prior art, such a device is not intended to establish a communication with a mobile terminal which receives the Beacon signal.

Advantageously, the invention proposes to use a Beacon signal to transmit to the mobile terminal connection data allowing the mobile terminal to establish communication with the device transmitting the Beacon signal, when the mobile terminal is near the device. transmitter.

In addition, according to the invention, the Beacon signal is transmitted by the sending device only on receipt of a trigger command via user interaction on the sending device.

Thus, the Beacon signal is not continuously emitted.

This makes it possible to limit the use of the resources of the sending device and of the mobile terminal.

According to a particular embodiment of the invention, the beacon identification field of said radio beacon signal is included in a payload field of a data packet of "Advertising" type of the "Bluetooth Low Energy" signal. ".

According to another particular embodiment of the invention, the reception method and the transmission method comprise the determination from a format of said connection data, of a communication mode according to which the request for The establishment of a communication must be sent to the sending device.

This particular embodiment of the invention makes it possible to adapt the mode of communication for establishing the communication between the mobile terminal and the sending device as a function of the sending device.

[0031] In addition, according to this particular embodiment of the invention, the communication mode for establishing the communication between the mobile terminal and the sending device can be distinct from the Bluetooth communication mode used to receive the communication. Beacon signal.

According to another particular embodiment of the invention, the connection data correspond to an SSID identifier according to the IEEE 802.11 standard of the sending device.

According to this particular embodiment of the invention, the transmitter device operates in WiFi access point mode.

Connection data is transmitted in an SSID (Service Set Identifier) type format, which is a 32-character alphanumeric key uniquely identifying a wireless network.

The SSID provided thus allows the mobile terminal to connect using WiFi technology to this access point.

For example, according to this particular embodiment of the invention, the sending device can be a WiFi repeater or a home gateway.

Description of an embodiment of the invention

FIG. 1 illustrates an environment for implementing the invention according to a particular embodiment of the invention.

Such an environment comprises a DEM transmitter device as described in relation to FIG. 4 described below.

Such a DEM transmitter device can be any electronic, computer or multimedia device capable of establishing a local communication (10) with a mobile terminal (TM).

By local communication is meant here a communication established with the mobile terminal when the mobile terminal is close to the mobile terminal.

Such a communication can be established using any communication protocol (WiFi, Bluetooth, or other) compatible with the two items of equipment involved in the communication.

The transmitter device can be of varied nature: domestic equipment (ADSL or fiber domestic gateway, TV decoder, connected television, game console, Hi-Fi audio system, voice assistant, Wi-Fi repeater, etc.), equipment IT (PC or Mac computer, mini-computer, Raspberry pi, Arduino or other similar system, tablet, mobile phone, etc.).

The transmitter device must at least support Bluetooth BLE to transmit a Beacon signal.

The sending device can support another inter-equipment communication technology, such as Wi-Fi for example.

The transmitter device can also be adapted to establish communications via a data network, for example an Internet network, a mobile network or even a local network (not shown here).

The environment also includes a mobile terminal (TM) such as a smartphone, a tablet, or any mobile terminal suitable for receiving and processing a Beacon signal.

The mobile terminal must therefore also support Bluetooth BLE in order to receive and interpret a Beacon signal.

The mobile terminal can also support another communication technology such as Wi-Fi for example.

The general principle of the invention is to use a Beacon signal in order to facilitate the establishment of a communication between a mobile terminal and a sending device.

The Beacon signal enables the sending device to transmit in its periphery the information necessary for establishing a one-way or two-way communication with the sending device.

The sending of such a Beacon signal also makes it possible to cause the “wake-up” of one or more mobile terminals, by reception of the Beacon signal, then to allow this or these mobile terminals to establish a communication with the device sending the device. Beacon signal, using the information contained in that signal.

The initial Beacon signal can be emitted as soon as the sending device is put into operation, or triggered following an event (pressing a button, detection of movement by a sensor, reception of information, etc. .).

This signal can be emitted "in loop" until the equipment is switched off, or for a given period of time.

In a particular embodiment of the invention, the sending device DEM is associated with a user interface (UI) on which a user can interact to trigger the sending of connection data by the sending device.

Such a user interface can be a dedicated button on the sending device.

FIG. 2 illustrates steps of a method of transmitting and of a method of receiving a signal comprising connection data according to a particular embodiment of the invention.

The transmission method is for example implemented by the transmitter device DEM and the reception method is for example implemented by the mobile terminal TM described in relation to FIG. 1.

During a step E20, the sending device detects a trigger signal for sending connection data.

Different variants of the trigger signal are possible depending on whether the communication to be established between the sending device and the mobile terminal is a communication initiated by a user or a machine-to-machine communication.

For example, the connection data sending trigger signal can correspond to a user interaction on an interaction interface (UI) associated with the sending device.

In this example, a user interacts on the interaction interface when he wishes to establish a communication between his mobile terminal (TM) and the sending device (DEM).

According to another example, the trigger signal for sending connection data corresponds to an expiry of a timer.

According to this example, the sending device (DEM) establishes a communication with the mobile terminal on a predetermined date and / or time, or at regular intervals, without requiring any interaction by the user of the mobile terminal.

Such an example corresponds for example to programmed machine-to-machine communications.

According to another example, the triggering of the sending of connection data corresponds to the reception of a signal by the transmitter device DEM.

Such a signal can be a signal transmitted by the mobile terminal TM when it passes near the transmitter DEM device 9 or else a signal transmitted remotely via a data network (not shown) and sent for example by a server (not shown). ) connected to the data network.

According to another example, the trigger for sending connection data corresponds to a received signal level, this received signal being transmitted by the mobile terminal.

According to this example, the detection step further comprises a step of measuring the level of signal received from the mobile terminal.

For example, it may be a measurement of the RSSI (for Received Signal Strength Indication) of a radio signal transmitted by the mobile terminal TM.

From such a measurement, the transmitter device DEM deduces therefrom the distance between the mobile terminal TM and the transmitter device DEM.

During a step E21, following the detection of the trigger signal, the transmitter device generates a radio beacon signal (Beacon) according to the specification "Bluctooth Low Encrgy" (BLE).

Such a Beacon signal comprises the connection data of the sending device allowing the mobile terminal to initiate communication with the sending device.

This login data is inserted into a beacon identification field of the Beacon signal.

Examples of the format of a Beacon signal are shown in Figure 3.

FIG. 3 illustrates different implementations of the payload (PLD, 32) of a Beacon signal (300):

- the iBeacon format (implemented by Applee),

- the AltBeacon format (implemented by RadiusNetworke),

- the Eddystone format (implemented by Googlee).

The “Bluetooth Low Energy” specification describes a data packet of the “Advertising” type comprising a payload (BLE Advertising PDU in FIG. 3) comprising a header (33) and a payload (32).

The format of the payload (32) is defined according to the Beacon signal implementation.

Whatever the implementation format, this type of data packet comprises a unique beacon identification field (30) which, according to the prior art, makes it possible to identify the beacon and / or the application associated with the Beacon signal. .

According to the invention, this tag identification field (30) is advantageously used to transport the connection data of the sending device.

This tag identification field (30) corresponds according to the implementation formats to the field: Proximity UUID (16 bytes), Beacon ID (20 bytes) or Eddystone Frame (20 bytes).

The connection data inserted in this identification field (30) depend on the communication mode according to which the sending device and the mobile terminal establish the communication.

For example, in the case of WiFi communication, the connection data correspond to an SSID of a WiFi connection point (sending device in access point, Ad hoc or WiFi Direct mode).

An SSID is an alphanumeric key of up to 32 characters that uniquely identifies a wireless network.

As a variant, when the SSID exceeds the size of the data zone used in the structure of the Beacon, this SSID can be transmitted in 2 times, by alternating the 2 parts in the broadcasting cycle of the Beacon signal.

According to another example, in the case of a communication to be established in Bluetooth, the connection data correspond to a Bluctooth MAC address, for example for a connection to a Bluctooth sockct server.

A MAC-48 address is 48 bits (6 bytes) long and is typically represented in hexadecimal form with the bytes separated by a colon or hyphen.

For example, such a Bluctooth MAC address can be of the form: 5E: FF: 56: A2: AF: 15.

According to a particular embodiment of the invention, the Beacon signal further comprises a code indicating a type of terminal corresponding to the sending device, and / or a service code identifying a service associated with the sending device.

Such codes can be transmitted in other fields of the Beacon signal.

These codes are used to enrich the connection data transmitted.

They can for example be transmitted in the Major and Minor fields (31) of the iBeacon format.

During a step E22, the transmitter device transmits the Beacon signal according to Bluetooth technology.

Conventionally, when this signal is transmitted, any terminal suitable for receiving and processing a Beacon signal and located near the transmitter device can receive this Beacon signal.

During step E22, the mobile terminal TM receives the Beacon signal sent by the sending device.

During a step E23, a native application of the mobile terminal detects that the received signal corresponds to a Beacon signal intended for a mobile application associated with this Beacon signal.

For example, the native application determines whether the Beacon signal includes either a MAC address or a WiFi SSID in the identification field (30).

Such a determination is for example implemented by analyzing the format of the data included in this field.

If the native application of the mobile terminal determines that the identification field (30) does not include either a MAC address or a Wi-Fi SSID, the native application wakes up a mobile application installed on the terminal corresponding to the identifier indicated in the identification field (30) of the Beacon signal.

If the native application of the mobile terminal determines that the identification field (30) includes a MAC address or a Wifi SSID identifier, the native application of the mobile terminal wakes up, during a step E24, the application mobile dedicated to this type of 11 signal Bcacon.

The mobile terminal then loads the computer program instructions implementing the mobile application into memory and executes them.

The following steps are then implemented by the mobile application executed by the mobile terminal.

During a step E25, the mobile application obtains from the Bcacon signal the connection data of the sending device.

For this, the mobile application reads the data included in the beacon identification field of the Bcacon signal.

[0100] According to a particular embodiment of the invention, during a step E26, the mobile application determines a communication mode according to which the request for establishment of a communication must be sent to the sending device.

Such a determination is implemented on the basis of the format of the connection data.

For example, if the connection data format corresponds to a MAC address, the communication should be established by Bluetooth technology, and if the connection data format corresponds to an SSID, the communication should be established by WiFi technology.

During a step E27, the mobile application sends to the sending device a request for establishing a communication using the connection data obtained.

Such a request for establishment of a communication is transmitted according to the communication mode determined during step E26, or else according to a technology determined by default during the implementation of the methods within the equipment.

Conventionally, during a step E28, communication is established between the mobile terminal and the sending device.

Such a communication can be unidirectional, for example the mobile terminal pushes information towards the sending device, or bidirectional.

[0103] During a step E29, the mobile terminal and the sending device exchange data via this communication.

For example, the mobile terminal can manage the sending device, or else obtain information or a service provided by the sending device.

This exchange of information can make it possible to provide on the mobile terminal services of the “remote screen” type, remote control, supervision, configuration, diagnostics, access to certain services, etc.
