Description

TECHNICAL AREA

The present invention generally relates to messaging systems, and more particularly, but not exclusively mobile social networks accessible for example by the Internet type computer network.

PRIOR ART

Over the last twenty years, messaging systems have evolved significantly. The SMS messaging service is an essential component of the mobile messaging service. Π Uses standardized communication protocols to allow mobile devices to exchange short text messages limited to 160 characters. The multimedia messaging service MMS extends the capabilities of SMS, and allows longer text messages, as well as the transmission of images, and audio and video recordings. The advent of social networks like Facebook ™ or Twitter ™ have improved messaging technologies with new communication possibilities.

Facebook offers a multi-purpose online social network. It allows users to publish different types of media on a centralized server, and share them with different categories of users such as friends or family.

Twitter is an online social networking service and microblogging service that allows its users to send and receive text messages up to 140 characters, called "Tweets", and also to receive "Tweets" published by the people being followed. Other types of social networks are called geosocial, in which geographic services and capabilities such as geocoding and geotagging are used to add new opportunities for social interactions. For example Foursquare ™ allows users to specify their location and interact with their current location, connecting and coordinating users with people or events that match their local interests.

The present invention is inspired by Post-it notes, which are small sheets of self-adhesive and removable paper, used to temporarily attach notes to documents or other surfaces.

The present invention aims to create new opportunities for social interaction by providing a social messaging system, and new methods for broadcasting messages between users through terminals having radio devices, and connected to an internet-like computer network. .

DETAILED DESCRIPTION OF THE INVENTION

The innovative aspects of the present invention will be described with particular reference to various exemplary embodiments. However, it will be understood by persons of ordinary skill in the field of the invention that certain embodiments may be practiced without these specific details. In other well-known cases, methods, procedures, and components have not been described in detail so as not to obscure the description.

In this document, the term "terminal" refers to any device that has a user interface and is capable of establishing communication over an Internet-type computer network (104). A terminal is assumed to have radio devices, and on which a computer program (200) executes. Smart mobile phones (smartphones), tablets, connected watches are an example of terminals.

The term user means a person registered on the server (101), and having both a user profile at the terminal (102) and the server (101). A user profile is a record in a database (208, 212) associated with a user, which contains information about the user's terminal, and personal information about the user. The information on the terminal includes, for example: the size and resolution of the terminal screen, the version of the operating system running on the terminal, but especially information on the radio devices integrated in the terminal, such as peripherals. Wi-Fi type radio (210), and Bluetooth (209).

The information about each radio device integrated in a terminal includes: the radio device identifier (physical address), the version of the communication protocol used by the radio device, and possibly the public name of the radio device, for example the SSID (Service Set IDentifier) of a Bluetooth-type radio device, or that of a Wi-Fi-type radio device. The information on a terminal is collected using the services provided by the Application (Application Programming Interface) (206) of the terminal.

A user's personal information includes: a unique UUID public identifier that serves to uniquely identify the user, and other information often present in a user's profile such as: a username, one or more images, preferences and settings.

In a first aspect, the present invention defines a method for searching for radio peripherals located near a terminal.

Mobile phones, modems, headsets, and many other devices use different radio devices to allow communication with other devices or to acquire data. The radio devices can be of different types depending on the radio technology used, for example: Bluetooth, Wi-Fi. To enable communication between devices, each radio device has a unique universal identifier (physical address), and may or may not be visible at other devices. When a radio device is visible, it is discoverable, i.e. other radio devices of the same type have the ability to search for and locate it, as long as it remains at a distance.

The distance from which the radio device is discoverable depends on the type of the radio device as well as the external environment of the radio device, such as the presence of physical obstacles between the radio devices. When a radio device is discovered by another radio device of the same type, its identifier, and possibly its public name, and the power of the radio signal transmitted by this radio device are known.

The power of the radio signal is often proportional to the geographical distance between radio devices, which can be used as a factor in determining the degree of geographical proximity between two radio devices.

The method of searching for radio devices located near a terminal is to receive at the server (101) information on the radio devices discovered directly by terminals, and a server-level analysis (101) of the information received on the radio devices, for inducing, directly or in combination, the discovery of one or more additional radio peripherals located near a terminal.

According to a preferred embodiment of the invention, the context module (203) at said terminal (102) provides for the continuous search and identification of radio devices located near said terminal (102), using the APIs of the radio devices (207) for launching search processes with each radio device integrated with said terminal. For example, using dudit Bluetooth of said terminal (102) to search for Bluetooth radio devices located near said terminal (102). The same process will be reproduced with other types of radio devices integrated in said terminal (102), such as the Wi-Fi type radio device.

Advantageously, to accelerate the search processes of the radio peripherals, and potentially save money on the power consumption of said terminal (102), since the loading of a radio device by said terminal (102) consumes energy, and this in a different way according to the type of the radio device, a user has the possibility to limit the searches on a particular type of radio peripherals, by specifying a preference through a user interface (202) the radio peripherals integrated to said terminal (102). ) which may or may not be used for searching for radio peripherals located near said terminal (102).

The profile management module (201) manages the user profile at said terminal (102), and makes it possible to save the settings and preferences expressed by a user in his user profile in the local database (208) of said terminal (102). ), and synchronizing the user's profile at said terminal (102) with the profile of the same user on the server (101). The user profile at the server level (101) is managed by the user management module (211).

The list of radio devices directly discovered by the context module (203) will be sent to the server (101) through the communication module (205), where it will be received and processed by the context module (213) at the server level. (101). This list is called radio devices discovered by the context module (203): the direct context of said terminal (102).

The communication module (205) provides reliable messaging between the computer program (200) and the server (101), ensuring that a message sent by the computer program (200) will actually be received at the server (101), and only once. The communication module (205) also receives messages sent by the server (101) to a terminal.

Advantageously, the frequency of sending the direct context of said terminal (102) can be chosen by the user through a user interface (202). For example, the user can choose a period of one to three minutes to send the list of radio devices directly discovered near said terminal (102), which can possibly reduce the energy consumption of said terminal (102), and reduce the communication with the server (101) through the internet network (104).

According to an advantageous embodiment of the invention, in order to optimize the flow of data sent from said terminal (102) to the server (101), only the changes in the direct context of said terminal (102) will be sent to the server (101), ie only new radio devices discovered, and radio devices that are no longer discoverable will be sent from said terminal (102) to the server (101).

When the server (101) receives the direct context of a terminal, it is saved by the context module (213) in the contexts database (214).

The context module (213) at the server (101) continuously receives the direct contexts of several terminals, and for each terminal, the context module (213) calculates an extended list of radio devices (called context extended) which is close to said terminal (102), and this in combination with the other direct contexts of other terminals.

Thus, for a so-called first terminal, the list of radio devices belonging to its extended context will include: 1) integrated radio devices of said first terminal, 2) direct context of said first terminal, 3) extended context of a said second terminal, if there is a radio device that belongs to both: the extended context of said second terminal and the extended context of said first terminal.

For example, the context module (203) of the terminal (102a) through its integrated Bluetooth type radio device (209) discovers the terminal's Bluetooth type radio device (102c) and the printer's Bluetooth type radio device. (105), and with its Wi-Fi radio device (210), discovers the Wi-Fi terminal (101). At the same time, the terminal (102b) discovers the wireless device of the wireless terminal (101), and the radio device of the audio headset (103). As a result, the direct context of the terminal (102a) will contain: the Bluetooth radio device of the terminal (102c), the Bluetooth radio device of the printer (105), and the wireless device of the Wi-Fi terminal (101).

The extended context of the terminal (102a) will contain the integrated radio devices of the terminal (102a), the direct context of the terminal (102a), the list of the radio peripherals integrated into the terminal (102b) and the list of the radio peripherals integrated into the terminal (102c ) and the Bluetooth radio device of the headphones (103).

In a second aspect of the invention, a method for enabling a user from said terminal (102) to publish messages by attaching them to radio devices.

According to a preferred embodiment of the invention, the computer program (200) provides a user interface (400) to enable the creation and publication of messages. A message may be composed of different types of content, such as text (401), images, sound or video (402), and possibly one or more Hashtag (407).

The target of a message is a list of one or more radio devices (radio device identifiers), and it is considered that a message is attached to a radio device, when that radio device belongs to the target of the message. The attachment of messages to radio devices can be done according to four methods of publication: Pin-to-Context, Tagging, Pin-to-Terminal, and Broadcast.

A publishing method defines which radio devices will belong to the target of a message, and to which terminal the message will be readable. The fact that a message is readable for a terminal means that this message is candidate to be selected by the server (101) from the message database (216) to be delivered to this terminal, and the fact that a message being read by a terminal means that this message has actually been delivered to this terminal.

According to the Pin-to-context publishing method, the target of a message is the set of radio devices of the direct context of the user's terminal at the time of sending the message to the server (101), and the message is readable only from a terminate having at least one of its embedded radio devices as the target of the message.

According to a preferred embodiment of the invention, to publish a message according to the Pin-in-context method, the user clicks on the button (403). Following which the messaging module (204) invokes the context module (203) to obtain the direct context of the user's terminal. The direct context of the terminai will be included as target of the message before sending the message to the server (101). Upon receipt of the message at the server (101). The messaging module (215) proceeds to the analysis of the message to determine and validate each part constituting the message: text, images, video, and also the target of the message ie a list of identifiers of radio peripherals, and the type the method of publishing the message. Then the message is saved in the message database (216).

In the case of Post-Context message publication, the messaging module (215) creates a record in the message database (216) to associate this message with each radio device of its target.

A message published according to the Pin-in-context method has a public scope, i.e. it is readable for any terminal having one of its radio peripherals integrated in the target of this message.

According to the publication method Marking, the target of a message published from said terminal (102) is the set of radio devices of the direct context of said terminal (102) at the time of sending the message to the server (101) , and the message is only readable for said terminal (102).

According to a preferred embodiment of the invention, to publish a message from said terminal (102) according to the Marking method, the user clicks on the button (405), and the messaging module (204) invokes the module of context (203) for obtaining the direct context of said terminal (102) to include it as a target of the message before it is sent to the server (101). Â When the message is received at the server (101), the messaging module (215) analyzes the published message to determine and validate each part of it: text, images, video, and also the target of the message. published message ie a list of identifiers of radio devices, as well as the type of publication method of the published message, then the published message is saved in the message database (216).

In the case of publishing a message according to the Marking method, the messaging module (215) creates a record in the message database (216) to associate the published message with each radio device of the message. target of this published message.

In the case of the Pin-in-context and Tagging methods, a user can choose (406) the target of a message, through a user interface (700), which makes it possible to select (704) radio devices from a list (703). This list (703) can be populated by loading the direct context of said terminal (102), by clicking on the button (701), or by loading the extended context of said terminal (102) from the server (101), by clicking on the button (702).

According to the pin-to-terminal publishing method, a user has the option of attaching messages to said terminal (102). The attached messages are either created by the user himself, or created by other users and read by said terminator (102).

Messages published according to the Pin-to-Terminal method from said terminal (102) are readable for any terminal having in its extended context one of the integrated radio devices of said terminal (102). This method significantly increases the propagation of messages between users by allowing the terminal (102) to be a messenger, so that these messages are readable to other terminals, as the devices integrated radio to said terminal (102) are discovered by other terminals, especially when the user moves geographically with said terminal (102).

According to a preferred embodiment of the invention, the publication of messages according to the pin-to-terminal method can be done according to three possibilities:

A user can explicitly through a user interface (501) attach a message read by said terminal (102) or created by itself to at least one of the integrated radio devices of said terminal (102).

A user can explicitly express through a user interface (202) a preference, according to which messages read by said terminal (102), and which have been published by himself or by another user will automatically be attached to said terminal (102) .

A user can explicitly specify through a user interface (202) a preference that any message read from a well-determined radio device through the user interface (700) will automatically be attached to said terminal (102).

When a user attaches a message to said terminal (102), the messaging module (204) sends a request to the server (101), which will be received and processed by the messaging module (215), which creates a new record in the message database (216) for associating this message with the integrated radio devices of said terminal (102).

According to a fourth possibility, a message can be published according to the Diffusion method, according to this method, the target of a message published from said terminal (102) will be the set of radio peripherals of the extended context of said terminal (102) at the time of the publication of the message, and the message will be readable to any terminal having in context extended at least one radio device on which the message is attached.

A message published according to the Broadcasting method and read by a said receiving terminal automatically becomes attached to the integrated radio devices of said receiving terminal, and will be readable for any terminal having in its extended context an integrated radio device of said receiving terminal.

According to a preferred embodiment of the invention, to publish a message according to the Broadcasting method from said terminal (102), a user clicks on the button (404). Then the messaging module (204) invokes the context module (203) to obtain the direct context of said terminal (102), which will be included in the target of the message before it is sent to the server (101). Upon receipt of the message on the server (101), the messaging module (215) analyzes the published message to determine and validate each part constituting it: text, images, video, and also the target of the message ie a list of radio device identifiers, as well as the type of the method of publishing the message, then the published message is saved in the message database (216).

When a message is broadcast-issued from said terminate (102), the server-level messaging module (215) invokes the context module (213) to obtain the extended context of said terminate (102). ), and then create a record in the message database (216) to associate the published message with all the extended context radio devices of said terminate (102).

According to an advantageous embodiment of the invention, a message attached to the radio devices of said terminal (102) can be released, so that it is no longer readable from an integrated radio device of said terminal (102). For example, a user has the option to explicitly release through the user interface (501) a message that has been previously attached to said terminal (102) according to the Pin-to-Terminal method or the Broadcast method.

A said first user can also express preferences through a user interface (501) so that the messages read by his terminal, and having been published by a said second user are never automatically attached to his terminal. A user also has the ability to explicitly specify through a user interface (706) that the messages read from a certain radio device are never attached to his terminal, or to disable through a user interface (301) any automatic attachment of a message read by his terminal.

According to a third aspect of the invention, a method for allowing a user, through his terminal, to read from radio devices, messages that have been published according to the publication methods described above. Radio devices are called from which a terminal can read messages: a message source.

To search and read messages, a said user reader expresses an explicit request to read messages from said terminal (102), and there are two possibilities according to the mode of specification of the source of the messages.

According to a preferred embodiment of the invention, the first possibility of explicit request to read messages by a said user reader from said terminal (102) is through the user interface (300) by clicking on the button ( 302). The messaging module (204) intercepts the request for reading messages expressed by said reader user, and invokes the context module (203) to obtain the direct context of said terminal (102), in order to include it in the read request messages that will be sent to the server (101). Upon receipt of the message reading request at the request processing module (218), this module (218) calls the context module (213) to obtain the extended context of said terminal (102). Then, the request processing module (218) invokes the messaging module (215) to retrieve a list of messages attached to the wireless devices of the extended context of said terminal (102) from the message database (216).

The request processing module (218) transmits the list of extracted messages to the filtering module (217) which applies a series of filters according to filtering criteria, including the preferences expressed in the profiles (212), both of said user reader and the users in relation to the extracted messages. For example, the filtering module may exclude messages published by another user by respecting a preference expressed by said user reader in his profile (212).

The filtering module (217) attributes ranks to filtered messages. The rank of a message indicates the priority that will be applied by the communication module (219) in sending the messages to a terminal. For example, several criteria are taken into account in order to determine the rank of a message, such as: the date of publication of the message, 2) The number of radio devices on which the message is attached, and which is close to said terminal (102), 3) The degree of proximity of said radio device terminal (102) from which to read the message. Two factors determine the degree of proximity between a terminal and a radio device, namely: the minimum number of terminals involved in calculating the extended context of the terminal that contains this radio device, and the number of times the radio device belonged to the device. extended context of the terminal.

The communication module (219) saves the list filtered and classified messages in the message queue (220), and sends the necessary information to allow the mail module (204) to progressively load the list of filtered and classified messages.

Messages received by said terminal (102) can be displayed at different zoom levels, for example, the user interface (303) displays a simple list of messages, which does not include all the details that a message may contain, such as multimedia content.

A user has the ability to display a detailed view of a message (500), where more details about the message are displayed (502), such as the multimedia content of the message.

Each message read by said terminal (102) includes information on the UUID of the user who published the message. A UUID identifies a user in a unique manner, and is included in all requests sent from said terminal (102) to the server (101) regarding the user identified by the UUID. For example, the UUID identifier of a said second user will be included in requests: to request a detailed view of a message published by a said second user, or to request by clicking on the button (503) the reading of the published messages according to the method Dissemination by said second user, through the user interface (600), and request by clicking the button (601) reading more and more messages published by the method Diffusion by said second user.

According to the second possibility of explicit request for reading messages, a user has the possibility from said terminal (102) to explicitly choose the radio devices of the source of the messages from a user interface (700) and express an explicit request for reading the messages. messages attached to the radio devices of the selected message source.

Once the radio devices of the source of the messages are selected (702), and a message reading request is made, the messaging module (204) sends to the server (101) a request to read the messages from the radio devices from the chosen message source. Upon receipt of the message reading request by the request processing module (218), the latter invokes the mail module (215), to extract the messages attached to each radio device of the source of messages selected from the base message data (216), applies filters and ranks the extracted messages in the filter module (217), then the communication module (219) saves the filtered and classified messages in the message queue (220), and sends the necessary information to enable the messaging module (204) at said terminal (102) to progressively load the list of classified messages.

Advantageously, in order to filter the radio sensors of a message source, a said user reader has the possibility of specifying through a user interface (501) the rejection of a said second user, so that no message published said second user will not be read by a terminator of said reader user, and also has the possibility to specify through a user interface (706) the rejection of a well-determined radio device through the user interface (700), so that that this radio device is excluded from the list of radio devices among which a terminal of said user reader can read messages.

According to a fourth aspect of the invention, a method for enabling a user through a user interface (800) to create and assign a social name to radio devices, with the possibility of sharing this social name with others. users. A social name is a short text, which is supposed to have meaning and easy to understand for users.

According to a preferred embodiment of the invention, the radio devices are displayed in a user interface (703) either by their identifiers or by their public names, but when a radio device has a social name, this social name is used. instead of the radio device identifier or public name, when it comes to displaying this radio device in the user interface (703).

A user has the ability to select one or more radio devices from the user interface (703), and launch by clicking the button (705) the user interface (800) to assign a social name (803) to the peripherals selected radio (801). Then, said user has the ability to share said social name or not with other users by declaring said social name respectively as public or private (802).

For example, a user can select a few radio devices belonging to the direct context of his terminal while at home through the user interface (700), and launch (705) the user interface (800) to assign a social name to the radio devices of the direct context of its terminal, for example "My house", and then declare this social name as private, which means that this social name will not be shared with other users.

A social name can be used to specify the target of a message when publishing messages, or the source of messages when requesting a message reading.

Thus, a user can restrict the target of a message to radio devices named by a certain social name. For example, a user can post a message using the Mark method by targeting radio devices named "My house". When the message is published, only the radio devices belonging to the direct context of said terminal (102), at the time of the publication of the message, among the radio devices named with the social name "My House" will actually be part of the target of the published message .

Also, a social name can be used to specify the source of the messages during a request to read messages. Thus, a user can explicitly specify the source of the messages by selecting a social name from the user interface (700). For example, a user can select the social name "My house" from the user interface (700). When this social name is selected, only the radio devices belonging to the extended context of said terminal (102), at the time of the request to read the messages, among the radio devices named with the social name "My House", will actually be part of the source of the messages of the message reading request.
