Abstract

The invention relates in particular to methods for managing: user communication terminals, the anonymisation of private user communication identifiers, and the use of private user communication identifiers. Upon designation of a social identifier of a first user, the aforementioned methods can be used to transmit one of the private communication identifiers associated with said first user to a communication establishment device for the purpose of anonymously connecting the first user with a second user having designated the social identifier.

Description

Method of managing the digital relationship

The present invention relates to the field of connecting people in a context of synchronous communication such as telephony or instant messaging or asynchronous such as electronic mail. The notion of "telephone line" or more generally of "communication line" covers in particular wireless access via cellular networks of GSM type (for "Special Mobile Group") for example. On the other hand, on a "telephone line", voice transport by GSM-type cellular technologies can be supplemented / replaced by voice over IP (for "Internet Protocol" in English) or VoIP, video transport. and / or data.

Increasingly, individuals are faced with an increase in professional and private calls and solicitations (phone calls, instant chats, e-mail, etc.) that can in some cases become significant and cause stress for individuals. In order to discriminate against the professional solicitation of private solicitations, individuals can use the use of several mobiles, the mobile phone can then be turned off at night.

However, such services are not free from defects.

For example, the fact of having two mobiles leads to additional costs and requires special attention from the individual: it is necessary to think of turning on the professional laptop in the early morning, to check the charge of the battery of the two phones, to turn off the professional laptop in the evening, etc.

In addition, if for a given reason a person from his or her professional sphere obtains the private telephone number, it can be very difficult to prevent that person from using this number and / or to disseminate it to colleagues. Similarly, it is not desirable to broadcast the business mobile phone number, for example, to commercial canvassing companies.

There is therefore a need to more effectively manage the linking of people during telephone calls, in particular to control the distribution of telephone contact data according to, in particular, the sphere of knowledge in which the person wanting to be put in contact with the receiver. The document US201 10069661 proposes to implement telecommunications functions between several users from a social network application, thereby keeping confidential the terminal identifiers (telephone numbers, IP address) of the participants. For this, the user's identifier in the social network and at least one terminal identifier are registered. This makes it possible to receive a request for linking to the user's identifier in the social network, to find the respective terminal identifier to establish communication with this terminal. The present invention improves the situation.

The invention proposes a method of linking at least one communication terminal of a calling user with at least one communication terminal, associated with a private communication identifier, of a called user,

said method comprising the following steps:

(a) receiving a connection request (dmd_mr2 (is_a), m2) from the communication terminal of the calling user (UE) and indicating a social identifier of said called user, at least one social identifier of a user being associated with at least one private communication identifier of a communication terminal of the called user;

(b) identifying (102, 105, m3) at least one private communication identifier based on said social identifier of the called user indicated in said match request based on at least one rule

(105) of reachability, configured by the called user, associated with the private communication identifiers;

(c) transmitting (106) a call establishment request (req_com (com_id_id, UE), m4) of the calling user's communication terminal with a communication terminal on which the called user is reachable on the base of the identified private communication identifier.

Thus, the invention makes it possible to route the calls to different call terminals of the called party according to the rules of closabilities and the caller. Advantageously, the step of identifying comprises a search of private communication identifiers associated by the user called to at least one social identifier of said called user, said search is performed according to a social identifier of said called user received in a request for connection.

Advantageously, the step of identifying comprises a selection of at least one private communication identifier of a communication terminal of said user from the private communication identifiers from said search, the selection being a function of rules (105) of reachability predefined.

Advantageously, the selection is, in addition, a function of a social identifier associated with a calling user of a communication terminal having sent to said social directory device said connection request.

(c) means for transmitting (443) a request for establishing a communication of the communication terminal of the calling user with a communication terminal on which the called user is reachable on the basis of the identifier identified private communication. The subject of the invention is an interface method for setting up a social network of at least one communication terminal of a calling user with at least one communication terminal associated with a private communication identifier. of a called user, said method comprising the step of transmitting (101) a connection request (dmd_mr2 (is_a), m2) from the communication terminal of the calling user (UE) and indicating an identifier said social user said called in said social network, at least one social identifier of a user being associated with at least one private communication identifier of a communication terminal of the called user, said connection request to identify (102, 105, m3) at least one private communication identifier on which said called user is reachable on the basis of said social identifier of the called user indicated in said placing request. ion based on at least one reachable rule (105), configured by the called user, associated with the private communication identifiers.

Advantageously, said method comprises a step of receiving an update message (updt (is_a)) from the connection request interface according to the reachability rules. Thus, the calling user can decide among several connection modes on which the called user is actually reachable at this time the one most suitable for his communication with less risk of not having his request for connection succeed.

The "linking of a calling user with a called user" is the fact, electronically, establishing a connection between a terminal of a calling user and a terminal of a called user. This linking is then solicited by the calling user.

A "private communication identifier" is a user identifier associated with a communication terminal: for example, the mobile phone number is a private communication identifier associated with a mobile phone comprising a SIM card associated with a mobile telephone account of a user. An e-mail address is a private communication identifier associated with a user's instant messaging account. A "private communication identifier" is said to be "private communication identifier" when said "private communication identifier" has not been published or broadcast in particular by a telephone directory or an e-mail address book.

A "social identifier" is an identifier associated with a given user in a social directory used or not by a social network. The user can then use his social identifier in social interactions with other people identified in this social directory. For example, this social identifier may be the full name of a user, which name is then written on the user's identity card (such as "John Smith") or a pseudonym. The "set of private communication identifiers of a user" is a set containing, for example, two landline numbers, a mobile phone number and an email address. These communication identifiers have been, for example, previously recorded in a database by the user.

The selection within private communication identifiers of a user of a private communication identifier verifying reachability rules, in particular according to the calling user, allows the establishment of a communication between a communication terminal of the user. calling user and the communication terminal corresponding to the selected private communication identifier of the user, also called called called user.

In a particular embodiment of the invention, the reachability rules may be a function of the type of communication terminal of the calling user. Thus if the calling user is identified by a telephone number, if the called user has declared a telephone number and not an e-mail address for example, the communication will be established between the communication terminals thus identified by the user. caller and the called user.

A "social directory" is a collection of social identifiers allowing users of a social directory to find people or companies. Today, social directories are mainly used by social networks to allow users to authorize or not knowledge to consult profile data, media such as photos, video, etc. The invention would make it possible to supplement the services provided by anonymous linking (in the sense of the communication and non-social information).

Figure 1 illustrates the particular representation of a method of managing communication identifiers in one embodiment of the invention.

The method for managing user communication identifiers comprises a REC_COM record, in a set of user private communication identifiers (UR), of at least one private communication identifier id_com_n declared by said user UR. The recording makes it possible to transmit to a communication establishment device (not shown in FIG. 1) at least one of the private communication identifiers. (id_com_1, id_com_n) associated with a social identifier of said user received in a connection request in a communication establishment request with a communication terminal of said user using said at least one of the private communication identifiers. The social identifier of said user has been, prior to receiving the matching request, associated with each of the private communication identifiers of said set of private communication identifiers s (UR).

In particular, the recording method comprises a reception 1001 of a declaration message 1000 of a new private communication identifier of a communication terminal (id_com_n) of a user (UR) triggering the recording 1002.

This record 1002 allows the storage in particular in a memory or a database 1003 of all the private communication identifiers of a user of the method of managing the communication identifiers. In particular, each user (UR) can have a reserved memory space 1004 in the database 1003. Each private communication identifier of the user (id_com_1, id_com_n) is stored in this reserved memory space 1004 in association with a identifier associated with the user (UR). The message 1000 advantageously contains an identifier UR making it possible to determine the user concerned by the declaration and the private communication identifier id_com_n to associate with this user. Thus, the recording step 1002 may consist in identifying the storage space associated with the user UR, then in the storage of the private communication identifier id_com_n in this space. In particular, the method of managing communication identifiers comprises an association 1006 of at least one rule or reachability information RJ with at least one registered private communication identifier id_com_n. The reachability rule can either be attached to the communication identifier declaration dcl (id_com_n, UR, <RJ>), or received separately. If a reachability information (RJ) is contained in the declaration message 1000, and the registration of this information is requested (1005), the reachability information (RJ) is recorded (1006) in the memory space 1004 in association with the private communication identifier id_com_n. The user can, by this method, configure reachability rules that govern the time periods or locations where it can be called according to the users who call it or groups of users designated respectively by their social identifiers or by the identifiers of knowledge groups if the social network allows this categorization.

Thus, a user UR can declare all of these communication identifiers at a moment in time, or declare them as and when they are created or used by a social directory, and add, delete or even modify either same time is later reachability rules associated with at least one of the identifiers of private communications declared.

In particular, one or more reachability rules can be added to a private communication identifier subsequently declared to the association of a social identifier with this private communication identifier. Thus, the rules can be a function of elements related to the social directory using this social identifier. In particular, the method of managing communication identifiers can, during the creation and / or modification of reachability rule, recover the social identifiers and / or contact knowledge group of the social identifier associated with the identifier of communication for which a reachability rule is edited (ie create, modify, or delete). Thus, the reachability rule may be a function of at least one of the social identifiers or group of contacts.

FIG. 2 illustrates the particular representation of an anonymization method (carried out by an anonymous linking service 4) and of an enrichment method in one embodiment of the invention. The anonymization method comprises a association 2002 of a social identifier of a user is_a with each of the private communication identifiers registered id_com_1 ... id_com_n in a set of private communication identifiers declared by said user UR. The association makes it possible to transmit to a communication establishment device (not shown) at least one of the associated private communication identifiers id_com_1 ... id_com_n to a social identifier of said user is_a received in a connection request in a request establishing communication with a communication terminal of said user using said at least one of the private communication identifiers. In particular, the anonymization method comprises the receipt 2001 of a request for anonymization of a social identifier dmd_X (is_a, UR). Upon receipt (2001) of an anonymization request message 2000 containing a social identifier (is_a) and the user identifier (UR), an anonymization can be performed. This anonymization can therefore consist of an association of the social identifier (is_a) communicated with each of the private communication identifiers registered for the user UR in the memory space associated with this user 1004.

Once the social identifier registered in the memory space 1004, an enrichment of a social directory system can occur.

The enrichment method comprises receiving a 2004 enrichment information. The enrichment information enables a social directory system 2 to issue a request for linking to a social identifier of a user. The connection request triggers a transmission to a communication establishment device (not illustrated) of at least one of the private communication identifiers associated with a social identifier of said user received in a connection request in a request for establishment communicating with a communication terminal of said user using said at least one of the private communication identifiers. The enrichment information is in particular a connection interface or an activation message of a connection interface.

In particular, the anonymous linking service 4 sends (2003) a message to the social directory system 2 which receives and processes it (2004). This message contains a connection interface allowing the social directory system 2 to issue a request for linking to the social identifier (is_a).

By way of illustration, this interface may be software used to make Internet telephony from a computer (or "soft phone" in English). The communications are then made by means of a microphone and a headset or speakers connected to the sound card, for example.

This interface is displayed to other users so that they can ask to be put in contact with the user UR by knowing only the social identifier (is_a) associated with it. In particular, the enrichment process includes the issuing of the request for anonymization 2000. In particular, a user UR consulting his profile or profile in a social directory or social network 2 may ask to allow his knowledge in this social directory of use at least one of its private communication identifiers (without distributing this communication identifier with this knowledge) by triggering the sending by the social directory of the request for anonymisation.

FIG. 3 illustrates the particular representation of the exchanges during the implementation of all the methods in one embodiment of the invention, in particular a communication identifier management method, an anonymization method, a method enrichment and a method of use.

An UR user uses one of his communication terminals 1 1 to declare one of his communication identifier that the user UR wishes not to broadcast, ie to keep private, in this case the communication identifier id_com_n used by the user. communication terminal 1 1: decl (id_com_n, UR) with an anonymisation service supply system (SA, 4), ie allowing communication to a terminal of a called user whose identifier private communication is known neither to the calling user nor to one of the communication terminals of the calling user.

The communication identifier management method (φ1) comprises a reception of this declaration by the user UR (1 1) of a new private communication identifier id_com_n as previously described with a device for managing the communication identifiers (DGT) of an anonymous linking service 4, and a record of this new private communication identifier by the communication identifier management device (DGT).

In particular, the user UR (1 1) sends a declaration (dcl (id_com_n, UR)) indicating his UR identifier, as well as the telephone number id_com_n (or other private communication identifier). As indicated above, the message may also include a reachability rule (RJ).

In a second step, the anonymization process (φ2) can be triggered by this same user. The user UR connects by means of a communication terminal 1 1 to a social directory service 2 to consult his profile or his card with which is associated a social identifier is_a. The user UR then requires this anonymization (dmdX) by means of his communication terminal 11, that is to say, to allow his knowledge in this social directory 2 to use at least one of his communication identifiers private (without disseminating this communication identifier with this knowledge) by triggering the sending by the social directory 2 of the anonymization request dmdX (is_a, UR) to the anonymous connection service 4, in particular to a device anonymizing DA of said anonymous linking service 4.

Then, the social directory service 2 informs the anonymous linking service 4 of this request by indicating the social identifier (is_a) associated with the user requesting this anonymization as well as the user's UR identifier with the service provider. in anonymous relationship (for example, a customer number for a mobile operator). The UR identifier could be previously configured by the user with the social directory service. The anonymous linking service 4 can therefore execute the anonymisation steps as described above (in particular in FIG. 2).

In particular, the anonymization device DA then associates the social identifier is_a of the user UR in this social directory 2 with the private communication identifiers of the user UR registered in the anonymization service provisioning system 4: en the occurrence in particular with the private communication identifier id_com_n: is_a <-Hd_com_n.

In parallel with the anonymization process (φ2) implemented by the anonymous linking service 4, an enrichment process (φ3) is implemented by the social directory service 2. In particular, an enrichment message such as that a connection request interface is sent after the anonymization request via an iter (is_a) message from the anonymous connection service 4 to the social directory service 3. The social identifier is_a enables the social directory service to know for which user this sent interface is associated. This enrichment message is either an interface that can be a "soft phone" type application as described above, or a simple piece of information enabling to activate or configure a pre-existing interface with the social directory service 2. Thus, a DMR interface (is_a) is created or configured with the social directory service. In particular, the social directory 2 then receives this interface and the load on the profile of the UR user. The social directory 2 then comprises, for the social identifier of the user UR, a DMR connection interface interface (is_a).

A new phase (φ1) for managing private communication identifiers including the addition of private communication identifiers or modification of reachability rules, and (φ2) of anonymization can take place at any time.

Moreover, a user device (DU) of the anonymous connection service 4 can update this DMR interface (is_a) according to the reachability rules configured by the user UR (eg "not available after 19h", etc.). This update is performed by sending an update message (updt (is_a)) from the device of use to the social directory service.

In particular, a user UE consulting, by means of a communication terminal 12 the social directory 2 is informed by the social directory 2 that in these contacts, the user UR allows a connection via this social directory 2 In this context, the user device DU can update updt (is_a) the information disseminated by the linking interface concerning, in particular, the connection statuses available for the social identifier is_a. In particular, if a reachability rule has been added to the communication identifier id_com_n indicating that the UE user can use this communication identifier only from 9h to 19h, the connection status corresponding to this communication identifier id_com_n will pass from available to unavailable for the UE user in the DMR connection interface at 19h.

If another user (UE) using, by means of a communication terminal 12, the social directory service wishes to be connected (φ4) with the user UR, he can use the DMR connection request interface. (is_a) registered by the social directory service: the user UE is then a calling user and the user UR a called user.

On receipt of the connection request (dmd_mr (is_a)) from the user UE by the social directory service via this interface, this connection request (dmd_mr2 (is_a)) is retransmitted to the user device DU. 4. The connection request comprises in particular the social identifier of the calling user UE in the social directory 2 and / or the communication identifier used by the communication terminal of the user. UE calling user with which the UE calling user wishes to be relationship with the user called UR: in this case the communication identifier used by the communication terminal 12.

Upon receipt of this request (dmd_mr2 (is_a)), the device DU uses at least one private communication identifier id_com_n associated with the social identifier is_a contained in this request in the database or memory 1003. The identification associated private communication identifiers may be a function of reachability rules configured by the user UR, including the social identifier of the calling user UE or its membership in a group in the social directory 2. In this case , the search provides the private communication identifier id_com_n used by the communication terminal 11 of the user called UR.

In particular, when the matching request only includes the social identifier of the calling user UE, the user device DU can search for a private communication identifier of the calling user UE associated with the social identifier of the user. the UE calling user if he has registered at least one communication identifier with the anonymization service provisioning system 4, the DU usage device can request the calling user UE to provide a communication identifier to the means of its communication terminal 12 with which it consults the social directory 2 (the request and its response are in particular exchanged via the social directory).

Once the private communication identifier id_com_n identified, the device DU uses a communication request (req_com (id_com_n, UE)) to the communication service 3 (SCOM) with the private communication identifier thus found id_com_n used by the communication terminal 1 1 of the user called UR, and a communication identifier (private or not) used by a communication terminal of the calling user UE, in this case the communication terminal 12.

The call establishment request is received by a communication system (SCOM, 3) which establishes two communication sessions or legacy of a communication session: The communication service 3 notifies (req_com1) then the communication terminal ^ of the UE user (by a ringing tone, for example, if the terminal is a telephone and the desired connection is a voice call). This communication server 3 also notifies (req_com2) the communication terminal 11 associated with the private communication identifier id_com_n (by a ringing tone, for example, if the terminal is a telephone and that the desired connection is a voice communication). If the users UE and UR accept the connection (ok1 and ok2), a communication can then be established between, on the one hand, the terminal of the user UE and the communication service 3, and on the other hand, between the communication service 3 and the terminal of the user UR. The communication server thus makes it possible to establish an ss_com communication session between the communication terminal 12 of the calling user UE and the communication terminal 11 of the user called UR without the user's communication identifier. called UR is known to the calling user UE or its communication terminal 12, or respectively respectively that the communication identifier of the calling user UE is not known to the user called UR or its communication terminal 1 1 .

In particular, the social identifier of the calling user UE in the social directory 2 is transmitted to the communication terminal 1 1 of the user called UR, respectively the social identifier of the user called UR in the social directory 2 is transmitted to the communication terminal 12 of the user called UE. The social identifier is in particular transmitted by the communication system 3 in the communication establishment request req_com allowing the establishment of the communication session or legacy between the communication terminal 11 or 12 and the communication system 3. The communication system 3 has in particular received this social identifier of the service providing anonymisation service 4. In particular, the social identifier of the calling user UE is either received from the social directory 2 by the service provider system. anonymizing service 4, which is found by this anonymization service provisioning system 4 during a reverse search if the calling user UE has declared the communication identifier used by the communication terminal 12 to the service provisioning system. anonymization service 4.

FIG. 4 illustrates an exemplary architecture of a communication network in one embodiment of the invention. The architecture comprises a communication terminal 11 of a user UR, a communication terminal 12 of a user UE, a social directory system 2, a communication system 3 and an information service provisioning system. 4.

The communication terminal 1 1 of the user UR comprises in particular three communication interfaces 1 12, 1 13, and 1 14. The communication terminal 1 1 of the user UR comprises a device for declaring communication identifiers 1 14 to the anonymization service provisioning system. In particular, the communication terminal 11 furthermore comprises:

- An application for anonymization 1 12 to a social directory 2, - A transmitter / receiver 1 13 for establishing a communication by a communication system 3.

Optionally, the anonymization request device 1 12 is a consultation and interaction device with a social directory 2.

The communication terminal 12 of the UE user comprises, in particular, a consultation and interaction device 122 with a social directory 2, and a transmitter / receiver 1 13 allowing establishment of a communication by a communication system 3 .

The social directory 2 includes an enrichment device 21 able to transmit a request for anonymization of a social identifier and to receive enrichment information of a social identifier such as a connection request interface or an activation information of a connection request interface.

Optionally, the social directory 2 further comprises a supply interface and interactions 22 including in particular a connection request interface (not shown).

The anonymization service provisioning system 4 comprises:

A device 41 for managing communication identifiers,

An anonymization device 43, and

A device for using private communication identifiers 44. In particular, the anonymization service provisioning system also comprises a database 42 in which the private communication identifiers declared by the management device 41 are registered, and if applicable, the associated reachability rules are associated with private communication identifiers and social identifiers. Thus, a user UR declares at least one communication identifier that he wishes to keep private by means of a communication terminal 11. The declaration device 1 14 transmits the private communication identifier declaration d2 a notification device 41 of the anonymization service provisioning system 4 which records it d3 in particular in the database 42.

The declaration device 41 is in particular a website that the user UR can consult by means of a communication terminal. In particular, the website allows secure access to a personal page on which the user can declare new communication identifiers as private, modify his declarations, or delete a communication identifier. In particular, in addition to the communication identifier, a category can be assigned such as "professional" or "family" to group together the communication identifiers usable by a group of identified knowledge.

This website also allows the UR user to manage its reachability rules.

The same user UR consults his card or profile on a social directory 2 by means of a communication terminal, in this case the communication terminal 1 1 (not shown). The communication terminal 1 1 by means of the anonymization request device 1 12 transmits on triggering by the user UR a request for anonymization a1 to the enrichment device 21 of the social directory 2 (hosting for example a social network ) which sends the request a2 to the anonymization device 42 of the anonymization service provisioning system 43.

The anonymization device 42 associates a3 the social identifier of the user UR in this social directory 2 with the private communication identifiers of this registered user UR (in particular in the database 42).

In particular, the anonymization device 42 transmits an enrichment information a4 such that a connection request interface is either directly in the supply and interaction device 22 of the social directory, or via the data communication device. enrichment 21 (not shown). Alternatively (not shown), the sending by the enrichment device 21 of an an2 request for anonymization triggers the activation of a linked request interface associated with the social identifier of the user UR the delivery device and interactions 22.

An update of the interface may be required by any user's terminal (d) from the interface 22 so that the latter informs anonymous connection service 4. This update may also, in complement or alternatively, to be automatically requested (c2) by the social directory service from the anonymous connection service 4. This update makes it possible to know, for example, the updated status of a user's status (defined, for example, by the reachability rules that this user has configured). The c2 update request is made in particular at the beginning of the consultation c1 and possibly periodically thereafter.

The use device 44 of the anonymization service provisioning system 4 checks c3 the types of connection available (synchronous such as telephone, instant messaging, chat ... or asynchronous such as electronic mail, SMS ...) in particular depending on the date, and / or time, and / or the social identifier of the UE user and / or its membership in a group of knowledge of the contact, etc. The utilization device 44 returns c4 of the linking statuses for each type of connection available for each of the contacts for which a connection is available to the supply and interaction device 22 which supplies them c5 to the communication terminal. 12. The UE user is thus informed (c5) of the reachability status of the user UR.

In addition, when a user UE wishes to be put in contact with the user UR, he can interact (m1) with the social directory service 2 via this interface 22. The interface 22 receiving the connection request (m1 ), it transmits it to the anonymous connection service 4 in a message (m2) to reception means (441) of the utilization device 44. Identification means 442 of the search utilization device (m3) then in the database or memory 42 if a private communication identifier associated with the social identifier contained the message (m2) exists. In the hypothesis where at least one private communication identifier exists (and is usable by the UE user under the reachability rules configured by the user UR), the transmission means 443 transmit (m4) the communication identifier private communication service 3 on its interface 31. The communication system 3 receiving the communication request m4 establishes two communication legs m'5 and m "respectively to a communication terminal of the calling user UE: in this case the communication terminal 12, and a communication terminal. call of the user called UR: in this case the communication terminal 1 1 to establish the communication session m6 between the communication terminals 11 and 12 respectively of the user called UR and the calling user UE without transmitting private communication identifiers. Figure 5 illustrates the particular representation of a method for calling a party by telephone in an embodiment of the invention.

When initiating a telephone call (step 101), the caller does not have the called party's telephone number. In fact, the caller only knows the social identifier of the called party, in particular on a social network (the caller is, in particular, a knowledge of the called party): for example, his full name, an avatar or a numerical identifier specific to the social network considered.

This so-called "social" identifier is then transmitted to the telephone operator instead of the telephone number, for example, in a GSM or SIP request (for "Session Initiation Protocol" in English) or even a separate request from the operator. phone call itself, as an HTTP request (for "HyperText Transfer Protocol" in English).

The telephone operator then proceeds to search for a real phone number of the called party (step 102) associated with this social identifier. This search can be carried out using a local database managed by the operator, or by a request made to a third party service, using an API (for "Application programming interface" in English) specific.

If the called party does not have a telephone number, or if the called party does not wish to be called by the caller, then the call can be declared failed. This last step is optional. A standard message may also be notified to the caller indicating that this call can not be completed.

The operator can verify that the reachability rules, configured by the person designated as the called party, are checked (step 105). For example, these rules may prohibit any call after 7pm on the business phone number. In addition, these rules can be used to filter calls, taking into account the community relations established in the social network, for example, based on the notion of groups, lists or circles (friends, acquaintances, colleagues, etc.). ). These rules may also be specific for each of the community relations of the person designated as the called party.

If the rules of the person designated as the called party do not allow his call (test 106, KO exit), the call is declared in check. This failure may be notified to the caller, or the caller may be directed to the called party's voicemail, if the called party has authorized the posting of a message (step 107). Otherwise (test 106, exit OK), the telephone call is initiated by the telephone operator (step 108): thus, the called party can be notified by ringing the wish of the caller to establish a telephone call with him.

Then, if the called party picks up (test 109, exit OK), a ticket of taxation is established with the telephone operator in order to be able to invoice the call to the caller (or the caller according to the model of taxation used) or count down the call of his phone plan (step 1 1 1).

If not (test 109, KO output), the call may be routed to the called party's telephone messaging (step 1 10).

Figure 6 illustrates the search for private communication identifiers associated with social identifiers in one embodiment of the invention.

Indeed, when establishing a telephone call according to the method detailed above, the caller does not know the phone number of his correspondent. Its connection request sent to the operator contains only the social identifier 302 of the recipient (i.e. the called party). Furthermore, the operator knows the caller's telephone number 301 (directly, for example, by his presence in the request or indirectly by the identification made during access to the mobile network of the operator). . The operator is then able to determine (step 303) the social identifier 305 of the caller in the social network. The correspondence between the caller's social identifier and the caller's telephone number may, for example, be prerecorded in a database by the caller to the operator or be dynamically retrieved from a network. by way of illustration, by means of a SOAP request (for "Simple Object Access Protocol" in English), HTTP (for "HyperText Transfer Protocol" in English), etc.

From the social identifier of the caller, the operator is then able to determine (step 306) whether the designated person (ie the called party) by the social identifier 302 belongs to the circle of friends, acquaintances, colleagues, etc. of the caller and possibly what are the rules for filtering calls. To do this, the operator can access APIs of the social network. If it is determined that the caller can be put in touch with the called party, the called party's telephone number 308 can be determined (step 307) if it has been pre-registered with the operator or if the one This is known from the social network.

Thus, from the social identifier of the caller and the telephone number of the recipient, it is possible to notify (step 309) the latter without disclosing the telephone number of the caller to the recipient, and without disclosing the recipient's phone number to the caller.

Ultimately, this method allows the telephone operator to determine the users to be connected without the caller knowing the phone number of the called party.

In addition, the operator may also not include in the call notification with the called party the caller's telephone number. The operator then acts as a trusted third party, able to connect the users but ensuring the confidentiality of the connection.

This device 500 is, for example, a server managed by a mobile operator. The server has an interface 501 in order to receive a message containing a private communication identifier of the calling user and a social identifier of the called user).

Once received and extracted, these identifiers are communicated to module 503 "correlation and decision". This module 503 can, for example, store these identifiers in the memory 504 for later use.

This module 503 then determines a social identifier of the calling user associated with the private communication identifier received. In addition, this module 503 also searches for at least one private communication identifier of the called user associated with the social identifier of the called user. These determinations / searches can be carried out thanks to a correspondence table between social identifiers and private communication identifiers previously recorded in the memory 504. It can be left the possibility users to create and modify the part of the correspondence table associated with them. Moreover, these determinations can be made by calling on a service of an external social network via the interface 506: an API provided by the social network can enable the module 503 to know the various usable identifiers associated with the identifier of private communication of the calling user.

In addition, this same module 503 can search for a private communication identifier of the called user according to reachability rules and in particular according to the calling user. For example, the module searches for a mobile phone number of the called party that the calling user can use at the time of the connection request. A message is then sent via the interface 505, for example, to a communication establishment server / module.

The block diagram shown in FIGS. 1, 2, 4, 5 or 6 is a typical example of a program, some of which instructions can be made to the anonymous connection service, the social network, the communication server or from the Internet. mobile equipment. As such, FIG. 1, 2, 4, 5 or 6 may correspond to the flow chart of the general algorithm of a computer program within the meaning of the invention. Of course, the present invention is not limited to the embodiments described above as examples; it extends to other variants.

Other achievements are possible.

For example, the figures above mainly present a user relationship of mobile terminals through a voice communication (telephone call for example), but the same presentation can be made with a connection through email, instant messaging, SMS, MMS, VoIP (for "Internet Protocol" in English) whose signaling is in particular carried out by the SIP protocol "for" Session Initiation Protocol "). In addition, when the description refers to a telephone number, it is also possible to substitute it for a unique identifier known to the operator or an identifier associated with the SIM card of a user of the mobile terminal (or more generally, to any communication identifier). The method described above is applicable to any type of social network, several social networks can even coexist for the same user. For example, a first electronic contact can be reachable on a personal mobile line of a subscriber associated with a social network of friends and a second electronic contact can be reachable on a company line associated with a social network company. The same line can be used at the same time by several social networks.

The call notification can be sent to the destination terminal in the form of a direct communication, a WAP message (for "Wireless Application Protocol" in English), an SMS (for "Short Message Service" in English), an MMS (for "Multimedia Message Service" in English), a message USSD (for "Unstructured Supplementary Service Data" in English).

Thus, the invention would allow a directory of yellow page or blank page type to allow people whose phone number is today on a red list to appear in a simple social directory without their phone number being published but by allowing their knowledge to be put in communication with them easily.

It could also be envisaged to provide users with network address book type services in which those who wish could provide only a public social identity. The social address book service will contact the anonymous contact service to enable the establishment of a communication with its people.

In a possible embodiment, for a connection between a calling user and a called user, the steps can be provided:

optionally, upon presentation of a private communication identifier of the calling user, determining a social identifier of the calling user associated with the private communication identifier of the calling user, on presentation of a social identifier of the called user, determining at least one private communication identifier of the called user associated with the social identifier of the called user,

- on verification of a reachability rule that can be a function of the membership of the calling user to a subset of the knowledge network of the called user in a social directory, and of reachability rules established by the called user, decide the connection between the calling user and the called user on the basis of the private communication identifier of the calling user and a private communication identifier of the called user thus selected.

Thus, the private communication identifier of the selected called user does not appear to the calling user. The connection can then be such that the private communication identifier of the calling user does not appear, for example, not to the called user either. The invention makes it possible to put the calling user in contact with the called user by not communicating any information relating to the private communication identifier of the called user to the calling user. It is possible to not communicate any information relating to the private communication identifier of the calling user to the called user user. Thus, the connection in the sense of the invention ensures an anonymization thereof (eg, telephone numbers, instant messaging addresses, etc.) of each of the parties put in relation.

The control of the use of the private communication identifier and its dissemination to its relationships within a social directory, or even a social network is then better controlled and is improved.

In a possible embodiment, the selection of a private communication identifier of the called user can be done according to predefined selection rules: reachability rules.

A user can, for example, associate with his social identifier a large number of private communication identifiers (for example, two instant messaging addresses, a professional landline number, a personal mobile number), according to a "map". electronic visit ". Nevertheless, it may wish that some of these private communication identifiers are not usable by certain users and / or at certain times of the day. Thus, reachability rules, for example, parameterized by this user, can allow a selection of private communication identifiers among all the private communication identifiers recorded by this user. The selection may then return one or more private communication identifiers usable at a given time and by a given potential calling user.

In addition, the method may comprise a compatibility check of the communication terminal of a calling user with a communication terminal associated with a selected private communication identifier of the called user. In case of non-verification of the compatibility criterion, the method may include a notification from the calling user.

Thus, if the private communication identifier of the calling user and the identifier selected within the private communication identifiers of the called user are not compatible, the calling user can be informed. For example, the notification may relate to the fact that no compatible private communication identifier for the called user has been found or that the reachability rules configured by the called user do not allow a connection between the calling user with the called user at the time of the connection request. In addition, the social identifier of the calling user can be displayed by the display device associated with the terminal of the called user.

Indeed, this display can allow the second user to identify the person wishing to be put in contact with him. Failing to display a phone number, another identifier can be displayed as a social identifier.

Similarly, the social identifier of the called user can be displayed by the display device associated with the terminal of the calling user.

Thus, this display can allow the calling user to verify that, failing to display a phone number of his correspondent, the person called is the right one, by displaying his social identifier.

In addition or alternatively, the social identifier of the calling user and the social identifier of the called user can be identifiers in a social network. A social network may comprise a set of users connected to each other by an online social networking service implemented over a communication network, for example, the Internet. On this social network, users can most often share information (photos, videos, etc.) with groups of acquaintances: friends, colleagues, etc.

In addition, the calling user may be in a knowledge group of the called user. The predefined reachability rules can include at least one reachability rule that governs private communication identifiers based on the knowledge group. As an illustration, the called user can configure certain reachability rules so that the personal mobile phone number can not be used by the knowledge group of his office colleagues.

Thus, the called user can fine-tune the setting parameters and protect his privacy. In addition, the predefined reachability rules can include at least one reachability rule governing the selection of private communication identifiers of the called user according to a given time data.

For example, the called user can set up certain contact rules so that the business mobile phone number can not be used after 7pm and / or on weekends.

In addition, the private communication identifier of the calling user and at least one of the private communication identifiers of the called user may be related to mobile telephony.

Thus, a connection can be made, the telephony operator can be in charge of the mapping between the social identifiers and the private communication identifiers.

In one embodiment, the calling user can have a contact list, in a social directory, the user can have a contact book consisting only of social identifiers allowing the user to recognize for each of the identifiers an associated user. Then, the method may comprise, for at least one contact (called user) and after determining private communication identifiers of said called user, an indication on the existence of a private communication identifier of said called user for connecting the calling user with the called user.

Contacts can be users as previously described. For example, in a dynamic manner, the user can visually determine which means allow the connection to his contacts. Indeed, the private communication identifiers can thus include private communication identifiers usable at a given time to connect the calling user and the contact: the called user. For example, the indication may then consist of the display of a specific icon according to the number and type of private communication identifiers. If no private communication identifiers are selected, the calling user can be informed that the connection is not possible. If the selected private communication identifiers include only an email address, the calling user can be informed that the linking is only possible via instant messaging or email, etc.

Of course, other types of indication may be considered as sound indications.

The invention relates to a method for managing user communication terminals, said management method comprising recording, in a set of private communication identifiers of a user, at least one private communication identifier declared by said user user, said record for transmitting to a communication establishment device at least one of the private communication identifiers associated with a social identifier of said user received in a connection request in a communication establishment request with a terminal of communication. communication of said user using said at least one of the private communication identifiers, said social identifier of said user having been, prior to the reception of the connection request, associated with each of the private communication identifiers of said set of private communication identifiers .

Thus, the present invention allows a better management of private communication identifiers by facilitating the use of private communication identifier allowing an anonymization of the connection, that is to say to allow to put in communication a terminal of communication. communication of a calling user with a communication terminal of a user called on request of the calling user without the calling user or his communication terminal knowing the communication identifier (including the telephone number) used by the communication terminal of the called user.

In one embodiment, the management method comprises associating at least one reachability rule with at least one registered private communication identifier.

Thus, the invention makes it possible to filter communications to a communication terminal of a user not only according to at least one reachability rule such as time, location, calendar, calling user
