Description

METHOD, SYSTEM AND SERVER FOR USING MOBILE PHONES, SUBSCRIBED TO A MOBILE TELEPHONY NETWORK, TO ANONYMOUSLY DIALOGUE IN REAL TIME

The present invention relates to a method, system and server enabling users of mobile telephones, subscribed to a mobile telephone network, to chat in real time anonymously. Mobile phone users would like to be able to reach other mobile phone users anonymously by voice. Users wish to remain anonymous, in particular in order to avoid disclosing their identity and / or their telephone address, in particular their mobile telephone number, and also in order to avoid being able to be called back on the telephone by users whom they have been able to reach previously and / or from which they do not wish to receive telephone calls. However, total anonymity creates a difficulty: at the end of a conversation, the called user cannot, by hypothesis, call back the calling user since he has no knowledge of his identity or his telephone address . Total anonymity thus prevents users from communicating effectively with one another and from forging links, particularly in the context of discussion forums. Telephone number masking systems are known in the prior art. The user of a mobile telephone can, if he wishes, hide his telephone number so that the mobile telephone network does not transmit it to the called user. This feature does not allow the called user to call the calling user later.

Likewise, a user can, if he wishes, refuse telephone calls which he does not wish to answer, either manually by not picking up his mobile phone when he rings, or automatically by configuring his mobile phone or the mobile telephone network, in particular so that anonymous calls or calls from a list of specific numbers are not forwarded to it.

It is also known from the prior art of anonymous voice messaging services allowing users to participate in anonymous and synchronous voice dialogs. However, these anonymous messaging services allow users to chat in real time anonymously only with people already connected to the service synchronously.

The invention solves the problem addressed. It relates to a method allowing users of mobile telephones, subscribers to a mobile telephone network, to chat in real time anonymously. The process includes:

- a user registration phase (I) with a connection server,

- a dialogue phase (II), between users, via the connection server.

(I) Registration phase

The process includes, during a registration phase, the following steps:

- the step, for users and / or for the connection server to determine separate anonymous identifiers telephone addresses, in particular mobile telephone numbers, users' mobile telephones,

the step of storing and associating, in a database of the connection server, the anonymous identifiers with the telephone addresses, in particular the mobile telephone numbers, of the mobile telephones of the users. (II) Dialogue phase

The method comprises, during a dialogue phase, the following steps: - the step, for a calling user, having a first mobile phone, to send a request to a called user having a second mobile phone connection via the connection server,

the step, for the connection server, of establishing synchronous telephone communication between the first mobile telephone of the calling user and the second mobile telephone of the called user.

The step of addressing, to the called user, the connection request via the connection server comprises the following steps:

the step, for the calling user, of inserting into the connection request, by means of the first mobile telephone, the anonymous identifier of the called user, the step of transmitting, by means of the first mobile telephone, the calling user, the request to the connection server,

the step, for the connection server, of detecting in the request the presence of the anonymous identifier of the called user and of searching in the database the telephone address of the second mobile telephone of the called user.

It results from the combination of technical features that the called user receives the request sent by the calling user without the calling user disclosing his identity and / or knowing the identity of the user called. It also results from the combination of technical features that, when establishing synchronous telephone communication, the calling user and the called user can maintain their anonymity. Preferably, according to the invention, the method is such that it further comprises the following steps: the step, for the connection server, of transmitting the connection request to the second mobile telephone of the called user, - l 'step, for the called user, having the second mobile phone, to respond to the connection request of the calling user by sending a response message to the connection server.

The step for the called user to respond to the connection request from the calling user by sending a response message to the connection server comprises the following steps:

the step, for the called user, of inserting into the response message, by means of the second mobile telephone, a signal for acceptance of the connection request,

the step of transmitting, by means of the second mobile telephone of the called user, the response message to the connection server,

Thus, the users 7, 9 of the mobile telephones 8, 11 can choose when and with which users 7, 9 they wish to communicate. The system is such that the third transmission means 26 of the connection server 4 make it possible to address to the first mobile telephone 8 and / or to the second mobile telephone 11 an instruction message 19 containing a connection procedure 20, in particular the actuation one or more keys 35 of the first and / or second mobile telephones 8, 11. The connection procedure 20 is intended to be executed by the calling user 7 and / or the called user 9, in particular by actuating one or more keys 35 of their respective mobile telephones 8, 11. Thus, the risk of putting the calling user 7 in contact with the voice mailbox of the second mobile telephone 11 of the called user (9), which may contain non-anonymous information, is avoided. The anonymity of the users 7, 9 is thus preserved. The system is such that the storage means 21 of the connection server 4 comprise association means 32 for associating, in the database 6 of the connection server 4:

A plurality of telephone addresses 34, in particular mobile telephone numbers, with a unique anonymous identifier 5, and / or

• a plurality of telephone addresses 34, in particular mobile telephone numbers, with a plurality of determined anonymous identifiers 5. Thus, the calling user 7 can, by sending a unique connection request 10 to the attention of a unique anonymous identifier 5, communicate synchronously with a plurality of called users, including the telephone addresses 34, in particular the numbers of mobile telephones, correspond to this same anonymous identifier 5. Thus, distinct anonymous identifiers 5 can correspond to the same plurality of telephone addresses 34, including mobile phone numbers. Thus, a calling user 7 can personalize the title of an anonymous identifier 5 without modifying the telephone addresses 34, in particular the mobile telephone numbers, to which the anonymous identifier 5 corresponds. The system is such as the connection request 10, sent by the user calling 7 to the user called 9 and / or the response message 12 sent by the user called 9 to the connection server 4 and / or the message notification 18 and / or the instruction message 19 and / or the connection message 14, transmitted by the connection server 4 to the first mobile telephone 8 and / or to the second mobile telephone 11:

• include text and / or audio data, in particular the recorded voice of the user calling 7 or the user called 9, and / or video data and / or images and / or signals of the DT F type and / or a visual signal, in particular a pictogram or an indicator light and / or

According to a first mode, the calling user 7 sends a connection request 10 to the connection server 4. The connection server 4 dials the telephone addresses 34, in particular the numbers of the mobile telephones, mobile telephones 8, 11 of the users 7, 9. The connection server 4 then connects the mobile phones 8, 11 of the users 7, 9.

According to a second mode, the calling user 7 sends a connection request 10 to the connection server 4. The connection server 4 dials the telephone addresses 34, in particular the numbers of the mobile telephones, mobile telephones 8, 11 of the users 7, 9. The connection server 4 sends a message to the mobile telephones 8, 11 containing a connection procedure 20. The users 7, 9 execute the procedure 20. The connection server 4 then links the mobile telephones 8, 11 of the users 7, 9.

According to a third mode, the calling user 7 sends a connection request 10 to the connection server 4. The connection server transmits to the mobile telephone 11 the connection request 10. The called user 9 sends a response message 12 containing a acceptance signal 13 to the connection server 4. The connection server 4 dials the telephone addresses 34, in particular the numbers of the mobile telephones, of the mobile telephones 8, 11 of the users 7, 9. The connection server 4 addresses the mobile telephones 8, 11 a message containing a connection procedure 20. The users 7, 9 execute the procedure 20. The connection server 4 then connects the mobile telephones 8, 11 of the users 7, 9. According to a fourth mode, the calling user 7 sends a connection request 10 to the connection server 4. The connection server transmits the connection request to the mobile telephone 11 10. The user called 9 address a response message 12 containing an acceptance signal 13 to the connection server 4. The connection server 4 dials the telephone addresses 34, in particular the numbers of the mobile telephones, of the mobile telephones 8, 11 of the users 7, 9. The server connection 4 then connects the mobile telephones 8, 11 of the users 7, 9. According to a fifth mode, the calling user 7 sends a connection request 10 to the connection server 4. The connection server transmits to the mobile telephone 11 the connection request 10. The called user 9 sends a response message 12 containing a acceptance signal 13 to the connection server 4.
