Definitions
- the field of the invention relates to the routing of a telephone call to a voice mailbox, and in particular an alias voice mailbox.
- a mobile communication terminal generally has a main call identifier allowing any person to establish a telephone communication with the user of the mobile communication terminal in question, on condition of course of knowing the main call identifier.
- the main call identifier is an identifier MSISDN (acronym for "Mobile Station International Subscriber Directory Number") corresponding uniquely to the SIM card (acronym for "Subscriber Identity Module”) provided by the operator of the mobile network with which the user of the mobile communication terminal has taken out a subscription.
- MSISDN acronym for "Mobile Station International Subscriber Directory Number”
- SIM card an identifier for "Subscriber Identity Module”
- this primary caller ID is the phone number of the mobile device in the mobile network.
- communication services guaranteeing the anonymity of a user offer to allocate a secondary call identifier to the terminal of a user who already has a primary call identifier.
- These communication services are for example offered to companies or businesses wishing to benefit from alias services.
- alias service when an employee of a company calls his customers via an alias service, it is a secondary call identifier, also called an alias number, which is presented to his customers, and not his call identifier.
- alias technology allows one or more "virtual" phone numbers to be associated with a "real" phone number that actually carries the communication.
- alias number such as a company number
- the actual phone number of the employee with which the alias number is associated is not disclosed.
- Such a telephone call is first of all redirected to a management platform. communication, more commonly known as an alias platform, which, knowing the real telephone number with which the alias telephone number is associated, redirects the telephone call to the real telephone number.
- the employee in question does not answer the customer's phone call, for example if he is absent or does not wish to answer, the customer's call ends in the voicemail of the real phone number, which may induce anonymity issues.
- the voice mail of the real telephone number can provide information concerning the identity of the employee called, for example his name or his first name.
- the employee may also wish not to overload the voicemail with his real phone number and prefer that this type of call, that is to say calls to his alias number, be redirected to their own voicemail. to the alias number.
- the same Secondary Call ID is shared between several Primary Call IDs.
- the same alias number can be shared between several users having different real telephone numbers. This case occurs in particular in the case of a company benefiting from a limited number of alias numbers used by the various employees to contact a customer.
- the present invention improves the situation.
- the present invention relates to a method of establishing a telephone call from a first communication terminal to a second communication terminal, the first and second communication terminals each having a main call identifier, the second communication terminal further having a secondary call identifier.
- the process includes:
- the method further comprises: in the event of no reception at the level of the communication management platform, from the second terminal, a favorable response to the second request:
- the invention preserves the anonymity of the user of the second terminal.
- the targeted method provides, when the user of the second terminal does not respond to the call from the user of the first terminal, to redirect the communication to a voicemail associated with the secondary call identifier.
- the voice mailbox selected at the level of the communication management platform is not the one associated with the primary number, that is to say the main call identifier, but a voice mail associated with the alias number, therefore the secondary call identifier. It is thus possible to take advantage of the fact that the user of the second terminal has subscribed to one or more anonymization services, also called alias services, to operate a voicemail associated with an alias number.
- the voice mail platform receives, via different channels, an identifier d. 'voicemail call associated with the secondary call identifier, and a telephone communication request aimed at establishing a communication between the first terminal and a voicemail with which the voicemail call identifier is associated.
- the voice mail call identifier associated with the secondary call identifier is transmitted, to the voice mail platform, by the communication management platform, via a channel different from the transmission channel of the request. telephone communication aiming to establish a communication between the first terminal and a voice mail.
- the same user can have several secondary call identifiers, each secondary call identifier having an associated voicemail.
- the invention is typically implemented when the user of the second terminal is an employee of a company, a business or an administration and the user of the first terminal is a customer wishing to resolve a problem or request a intelligence.
- the customer does not have the employee's real number which is a private number but has an alias number.
- the telephone communication request aiming to establish a communication between the first terminal and said voice mailbox comprises the secondary call identifier and / or the main call identifier of the second terminal, one of said identifiers being used to correlate said voicemail call identifier and said telephone communication request to establish communication between the first terminal and said voicemail.
- the voice platform thus makes the link between the received voice mail call ID and the telephone communication request and transfers the latter to the voice mail corresponding to the received call ID.
- the method further comprises:
- This first embodiment therefore aims to anticipate an unfavorable response from the user of the second terminal or an absence of reception, at the level of the communication management platform, of a favorable response.
- the third request is sent to the voice mail at the same time as the second request is sent to the second terminal. This early transmission allows the user of the first terminal to be quickly put into telephone communication with the voicemail of the alias number when the user of the second terminal does not answer the call.
- the method further comprises, in the absence of reception, at the level of the communication management platform, of a favorable response to the second request from the second terminal:
- This second embodiment makes it possible to prevent the sending of the third request to the voicemail associated with the alias number from being unnecessarily implemented.
- the sending of the third request to the voice mail is implemented for example via an application programming interface of a voice mail platform.
- the voicemail platform extracts the voicemail call identifier included in the third request and routes the third request to the voicemail. As shown below, the voicemail call identifier is addressed to a messaging platform through a data channel.
- the transmission of the third request to the voice mailbox results in the transmission of a first sub-request and a second sub-request.
- the first sub-query corresponds to a voice call to record a voice message on the voice mail.
- the second sub-request corresponds to a call to the application programming interface.
- the first and second sub-queries correlate at the voicemail platform or voicemail level.
- the third request transmitted by the communication management platform to the voice mail corresponds to two distinct requests.
- the first of these requests is in fact a classic telephony request, a voice call.
- This request contains the primary call identifier of the second terminal and carries the communication between the first terminal and voicemail. This first request therefore allows the user of the first terminal to leave a voice message.
- the second of these requests is an API call (also known as "API call").
- API call also known as "API call”
- This request contains the primary call ID or secondary call ID of the second terminal and the voicemail call ID.
- the correlation between these two requests which therefore constitute the third telephone communication request within the meaning of the invention, is carried out at the level of the voice mail or of the voice mail platform so that the user of the first terminal can record his message. voice mail in the voice mailbox selected for this purpose.
- the voice mail call identifier is selected from a database registered on or connected to the communication management platform.
- the first request is routed to the communication management platform via an interactive voice server, the communication management platform thus receiving, in addition to the first request, input data characterizing a service required by a user of the first terminal.
- the obtained voice mail call identifier is selected as a function of said service.
- the secondary call identifier, the required service and the voicemail call identifier are associated within the database.
- the input data is generated for example via one or more interactions of the user with an application of the telephone dialer type of the first terminal and / or via voice information supplied by the user of the first terminal.
- the database is organized as follows: at least one secondary call identifier is stored in the database in association with a service and a voice mail call identifier.
- the communication management platform extracts the secondary call identifier of the first request as well as the service corresponding to the input data provided by the user of the first terminal via the interactive voice server.
- the combination of the secondary call identifier dialed by the user of the first terminal and the identified service makes it possible to select the appropriate voicemail call identifier, and therefore the corresponding voicemail mailbox.
- the same secondary call identifier can be shared by several primary call identifiers.
- the pair formed by a secondary call identifier and a given service can be associated not only with a voice mail call identifier but also with a primary call identifier of a called terminal (for example the second terminal), or one of the real numbers associated with the virtual number that constitutes the secondary call identifier.
- the communication management platform can also, if this secondary call identifier is shared by several identifiers of main calls, search the database for the main call identifier, here the main call identifier of the second terminal, associated with the pair formed by the secondary call identifier and the required service.
- the obtained voicemail call identifier is selected based on the primary call identifier of the first terminal.
- the secondary call identifier, the primary identifier of the first terminal and the voicemail call identifier are associated within the database.
- the database is organized as follows: at least one secondary call identifier is stored in the database in association this time with a calling principal call identifier, for example here the principal call identifier of the first terminal, and a voicemail call identifier.
- the communication management platform extracts the secondary call identifier of the first request as well as the main call identifier of the terminal sending the request, therefore the calling terminal,
- the combination of the call identifier secondary dialed by the user of the first terminal and the primary call identifier of the calling terminal makes it possible to select the appropriate voicemail call identifier, and therefore the corresponding voicemail.
- the pair formed by a secondary call identifier and a main call identifier of a calling terminal can advantageously be associated not only to a voice mail call identifier but also to a main call identifier of a called terminal (for example the second terminal), ie one of the real numbers associated with the virtual number that constitutes the secondary call identifier.
- the communication management platform can also, if this secondary call identifier is shared by several main call identifiers, search the database for the main call identifier, here the main call identifier of the second terminal, associated with the pair formed by the secondary call identifier and the 'main call identifier of the calling terminal.
- the respective primary caller ID of the first and second terminal, and the secondary call ID of the second terminal are MSISDN identifier type telephone numbers.

- the communication module COM is further designed to communicate with the voice mail MV selected by the PGC platform based at least on the secondary call identifier IAS of the second terminal TC2. It will be understood that the communication module COM is designed to send the third request REQ3 to the voice mailbox MV. Sending the third REQ3 request to voicemail opens a third communication channel. More specifically, as explained in the remainder of the description, the communication module COM is arranged to send the third request REQ3 to the voice mail platform PMV so that the latter routes the third request REQ3 to the voice mailbox. MV.
- issuing the third REQ3 request results in issuing an API call and a voice call.
- the third communication channel corresponds to the communication channel carrying the voice call and therefore allowing the user of the first terminal to leave a voice message.
- the API call is sent via a data channel or data channel independent of the third communication channel. The content of the sub-requests making up the third REQ3 request will be detailed below.
- the communication module COM is also designed to receive a possible favorable response to the second request REQ2 coming from the second terminal TC2.
- the processing unit U NT is arranged to implement a method making it possible to redirect (or route) the telephone call from the first terminal TC1 to the second terminal TC2 when this telephone call is accepted by the user of the second terminal TC2.
- the method implemented by the processing unit UNT makes it possible to redirect (or route) the telephone call from the first terminal TC1 to the voice mailbox MV associated with the secondary call identifier IAS of the second terminal TC2 in the absence of reception at the level of the platform PGC of a favorable response from the second terminal TC2 to the second request REQ2. This method will be described in more detail in the remainder of the description with reference to FIG. 3, then to FIG. 4.
- the switching center CMT is connected to the processing unit UNT and is arranged to process the path of the communication established from the first terminal TC1 to the second terminal TC2 or to the selected voice mailbox MV.
- the CMT switching center is connected directly or indirectly to well-known network equipment such as, for example, a mobile switch (known by the acronym MSC for "Mobile Switching Center") of a mobile telecommunications network.
- the CMT switching center can be connected to a local switch of a fixed telecommunications network.
- the local switch handles local calls from subscribers on the same switch as well as originating and terminating traffic with other switches.
- one of the main functions of the CMT switching center is a call control function implementing various operations such as decoding of address information and routing of telephone calls from the first calling terminal TC1 to the second. TC2 terminal called.
- Such a function is associated with certain call functions such as:
- pre-hook which consists of broadcasting a message to the user of the calling terminal to make the latter wait while the called terminal is ringing.
- the method described below implemented by the processing unit UNT at the level of the PGC platform allows, when the telephone call sent by the first terminal TC1 uses the identifier IAS secondary call of the second terminal, to redirect the telephone call in question to the voice mailbox selected by the PGC platform, and not to the voice mailbox (not shown here) associated with the call identifier main IAP2 of the second terminal TC2.
- the DB database is connected or integrated into the PGC platform. More exactly, the database DB is connected to the processing unit UNT.
- the database DB is registered on the PGC platform. However, more generally, the DB database is simply connected to the PGC platform. For example, the DB database can be accessible to the PGC platform remotely.
- the database DB is designed to store data relating to the communication terminals likely to request a telephone communication through the PGC platform.
- the main call identifier of each communication terminal is stored in the DB database.
- the main call identifier IAP1 of the first terminal TC1 is stored in the database DB, as is the main call identifier IAP2 of the second terminal TC2.
- each primary call identifier is associated with one or more secondary call identifiers if the user of the terminal identified by the primary call identifier has subscribed to an anonymization service for have such secondary call identifiers, or alias numbers.
- each secondary call ID is associated with one or more primary call IDs.
- the database DB indicates that the first terminal TC1, associated with the primary call identifier IAP1, does not have a secondary call identifier.
- the DB database indicates that the second terminal TC2, associated with the primary call ID IAP2, is associated with at least the secondary call ID IAS. It is possible for the same communication terminal to be associated with several secondary call identifiers. It is also possible for the same Secondary Call ID to be shared among multiple Primary Call IDs. In other words, the same alias number can be shared between several users having different real telephone numbers.
- the database DB is also designed to store a voice mail call identifier associated with each listed voice mail.
- a primary call identifier is associated with a voicemail
- the voicemail call identifier associated with this voicemail is associated within the database DB with this main call identifier.
- a secondary call identifier is associated with a voicemail
- the voicemail call identifier associated with this voicemail is associated within the database DB with this secondary call identifier.
- a secondary call identifier can be shared between several main call identifiers, the same is true for the voice mail associated with such a secondary call identifier and therefore for the voice mail call identifier corresponding to this Voice Messaging.
- a voicemail call identifier allows the PGC platform to establish telephone communication with the associated voicemail.
- the Secondary Call ID IAS is associated with at least the Voicemail Call ID IAMV corresponding to Voicemail MV.
- this IAMV voice mail call identifier is sent by the management platform PGC to the voice mail platform, to allow the establishment of the telephone communication between the first terminal TC1 and the good MV voicemail, that is, the MV voicemail associated with the IAMV voicemail call identifier.
- the database DB therefore stores the IAMV voicemail call identifier of the MV voicemail.
- a primary or secondary call identifier can be associated with several voice mailboxes.
- the primary or secondary call identifier is associated, within the database DB, with several voicemail call identifiers, each associated with a separate voicemail.

- the voice mail MV is associated with the secondary call identifier IAS of the second terminal TC2. It is understood that the voice mail MV is distinct from the voice mail associated with the main call identifier IAP2 of the second terminal TC2.
- the MV voice mail can be associated with a service.
- the interactive voice server SVI when the first request REQ1 is sent by the first terminal TC1 to the PGC platform via the interactive voice server SVI, the interactive voice server SVI generates, thanks to the inputs supplied by the user of the first terminal TC1, data d 'Entrance.

- the determined service makes it possible to select, from among the voicemail call identifiers associated with the secondary call identifier IAS, the voicemail call identifier, here the voicemail call identifier IAMV associated with the appropriate MV voicemail for the required service.
- This voice mail is thus the voice mail designated to receive and store the voice messages of users requesting the same service.
- the voice mail MV is designed to store one or more voice messages left by the user of a communication terminal, here the user of the first terminal TC1, when he has not been able to enter into communication. telephone with the user of the second terminal TC2.
- the stored voice messages are intended to be returned to the user of the second terminal TC2 when the latter accesses the voice mailbox MV.
- the voice mail MV is designed to perform other optional functions, such as for example broadcasting an automatic voice message or recorded by the user of the second terminal TC2 announcing the unavailability of the user of the second terminal TC2 and inviting the user to first TC1 terminal to leave a voice message.
- a method of establishing a telephone call from the first terminal TC1 to the second terminal TC2 will now be described with reference to FIG. 3, according to a first embodiment, then with reference to FIG. 4, according to a second embodiment.
- this method also aims to establish, if necessary, a telephone communication between the first terminal TC1 and the voice mailbox MV associated with the secondary call identifier IAS of the second terminal TC2.
- the context of the implementation of the method is as follows: the user of the first terminal TC1 wishes to contact the user of the second terminal TC2 via a telephone communication.
- the second terminal TC2 is associated with a main call identifier IAP2, which corresponds to the "real" number carrying the communication, and with a secondary call identifier IAS, which corresponds to an alias number or "virtual" number.
- the user of the first terminal TC1 uses the secondary call identifier IAS to attempt to establish a telephone call with the user of the second terminal TC2.
- the user of the first terminal TC1 dials, thanks to an application of the telephone dialer type of the first terminal TC1, the alias number corresponding to the secondary call identifier IAS to start the telephone call.
- the first terminal TC1 generates a first telephone communication request REQ1.
- This first request REQ1 comprises the main call identifier IAP1 of the first terminal TC1 and the secondary call identifier IAS of the second terminal TC2.
- This first request REQ1 which therefore corresponds to a telephone call, is sent by the communication module COM1 to the platform PGC.
- the first embodiment of the method for establishing a telephone call from the first terminal TC1 to the second terminal TC1 is described below with reference to FIG. 3.
- the platform PGC receives an incoming call, namely the first request REQ1 from the first terminal TC1. More precisely, the first REQ1 request is received by the communication module COM of the PGC platform. The first REQ1 request is sent by the first terminal TC1 to the PGC platform via a first communication channel open for this purpose. It is then commonly said that the PGC platform maintains the call coming from the first terminal TC1.
- the first request REQ1 is routed to the PGC platform via the first network RES1, and more precisely via the interactive voice server SVI.
- the user of the first terminal TC1 is required to interact with the PGC platform via the interactive voice server SVI.
- the user interacts, for example, with the IVR interactive voice server via the Human-Machine interface IHM2.
- the user of the first terminal TC1 uses, in response to the various voice menus presented to him, a telephone dialer type application to press one or more keys. Presses by the user on the keys then generate sound frequencies corresponding to DTMF codes. These DTMF codes constitute inputs for the preprogrammed logic of the IVR interactive voice server.
- the user of the first terminal TC1 provides inputs to the IVR interactive voice server via voice information.
- the PGC platform then receives not only the first request REQ1, comprising the main call identifier IAP1 of the first terminal TC1 and the secondary call identifier IAS of the second terminal TC2, but also the input data generated as a function of the inputs provided by the user of the first terminal TC1. These input data characterize a service required by the user of the first terminal TC1.
- the PGC platform searches, within the database DB, the main call identifier IAP2 associated at least with the secondary call identifier IAS.
- the database DB indeed stores a correspondence between, on the one hand, a main call identifier of a terminal and, on the other hand, the associated secondary call identifier (s) as well as the identifier (s) of a terminal. 'voice mail calls for each secondary call identifier.
- the PGC platform determines the main call identifier IAP2 of the second terminal TC2 associated with the secondary call identifier IAS of this same second terminal TC2.
- Secondary Call ID IAS can be associated not only with the Primary Call ID IAP2 but also with other primary Call IDs.
- the present invention therefore proposes two solutions for determining the appropriate main call identifier, here for example the main call identifier IAP2.
- a first solution is to select the main call identifier IAP2 as a function not only of the secondary call identifier IAS but also as a function of the service required by the user of the first terminal TC1.
- This service can be identified using inputs provided by the user of the first TC1 terminal via the IVR interactive voice server.
- This solution assumes that, with each pair formed by a secondary call identifier and a given service, there is associated a main call identifier such as the main call identifier IAP2 of the second terminal TC2. This association is for example pre-recorded in the database DB.
- a second solution is to select the main call identifier IAP2 as a function not only of the secondary call identifier IAS but also as a function of the main call identifier IAP1 associated with the first terminal TC1.
- This solution can be implemented typically by associating, for example during the first call of the user of the first terminal TC1, the call identifier main IAP1 of the first terminal TC1 combined with the secondary call identifier dialed by the user of the first terminal TC1 with the main call identifier IAP2. This can also be done by first declaring in the database a link between the first terminal TC1, the main call identifier IAP2 and the secondary call identifier IAS.
- the pair formed by the secondary call identifier IAS and the voicemail MV can be associated with both the service required by the user of the first terminal TC1 and the main call identifier IAP1. It is also possible that, within the database DB, certain pairs formed by a secondary call identifier and a voice mailbox are associated with a given service while other pairs are associated with a given service.
- main caller call identifier such as the main call identifier IAP1 of the first terminal TC1.
- the PGC platform selects, within the database DB, a voice mail call identifier associated at least with the secondary call identifier IAS of the second terminal TC2.
- each Voicemail Call ID can correspond to a service.
- the PGC platform can then select, from among the voicemail call identifiers associated with the secondary call identifier IAS, the voicemail call identifier corresponding to the service required by the user of the first terminal TC1. This service is for example determined according to the input data received by the PGC platform.
- the PGC platform receives, in addition to the first REQ1 request, input data characterizing the service required by the user of the first TC1 terminal.
- the PGC selects, from among the voicemail call identifiers associated with the secondary call identifier IAS, the voicemail call identifier corresponding to that service.
- the IAMV voicemail call identifier associated with the MV voicemail is selected.
- the secondary call identifier IAS the service required by the user of the first terminal TC1 and the voicemail MV, therefore the voicemail call identifier IAMV, are associated, by example within the DB database to which the PGC platform can access.
- the voice mail MV and therefore the voice mail call identifier IAMV, according to the secondary call identifier IAS and the primary call identifier IAP1 of the first one.
- the PGC platform retrieves both the secondary call identifier IAS and the main call identifier IAP1 then determines the voice mail, here the voice mail MV, associated. This association is for example stored in the database DB.
- the PGC platform determines whether the pair formed by the secondary call identifier IAS and the primary call identifier IAP1 is already associated, for example in the database DB, with a voicemail such as MV voicemail, therefore to the IAMV voicemail call identifier. If so, the IAMV voicemail call ID is retrieved by the PGC platform. Otherwise, a voice mailbox, advantageously available, is selected by the PGC platform and then associated with the secondary call identifier IAS and with the primary call identifier IAP1. Such an association makes it possible, during a subsequent call from the user of the first terminal TC1 again composing the secondary call identifier IAS, to retrieve the voice mail identifier IAMV again.
- the PGC platform generates, during a step S34, a second REQ2 telephone communication request.
- the second request REQ2 includes the main call identifier IAP1 of the first terminal TC1 and the main call identifier IAP2 of the second terminal TC2.
- the platform PGC sends the second request REQ2 to the second terminal TC2. More precisely, this second request REQ2, which corresponds to a telephone call, is sent by the communication module COM to the communication module COM2 of the second terminal TC2.
- the second REQ2 request is sent to the second terminal TC2 via a second communication channel opened by the PGC platform for this purpose.
- the platform PGC sends, in parallel or following the transmission of the second request REQ2, a third telephone communication request REQ3 intended for the voice mail MV associated with the voice mail call identifier.
- the third request REQ3 comprises the main call identifier IAP1 of the first terminal TC1 and the identifier Voicemail MV IAMV call call.
- the transmission of the third request REQ3 opens the third communication channel.
- the transmission of the third request REQ3 to the MV voice mail is implemented via the PMV voice mail platform. More specifically, the reception of the third REQ3 request is implemented via the IP application programming interface.
- the PMV platform receives the third request REQ3 then extracts the information necessary to determine the voice mail for which the third request REQ3 is intended. In this case, the PMV platform extracts the IAMV voicemail call ID and routes the third REQ3 request to the MV voicemail associated with the IAMV voicemail call ID.
- the sending of the third request REQ3 results in the sending of both an API call and a voice call, for example a call sent according to the SIP protocol for “Signaling Internet Protocol”, in English terminology. ), each being sent to the PMV voice mail platform via a specific channel.
- the PMV voice mail platform is able to correlate the API call with the voice call and identify them as components of the same REQ3 telephone communication request.
- the PGC platform is waiting to receive, from the second terminal TC2, a favorable response to the second request REQ2.
- the PGC platform is also waiting for a possible unfavorable response from the second terminal TC2, indicating that the user of the second terminal TC2 has refused the incoming call.
- the PGC platform is on standby for a predetermined period of time. If, at the end of this predetermined period of time, the PGC platform has received neither a favorable response nor an unfavorable response to the second request REQ2 originating from the second terminal TC2, this lack of response is assimilated by the PGC platform to a unfavorable response.
- the steps S37 and S38 detailed below are implemented in the event of reception at the level of the platform PGC of a favorable response to the second request REQ2 originating from the second terminal TC2.
- step S37 the PGC platform connects the first and second communication channels to establish telephone communication between the first terminal TC1 and the second terminal TC2. Indeed, until this step of the method, the telephone call from the first terminal TC1 was put on hold by the PGC platform, and the telephone call from the PGC platform to the second terminal TC2 was also put on hold. The user of the first terminal TC1 can then enter into communication with the user of the second terminal TC2.
- step S38 the PGC platform closes the third communication channel.
- the issuance of the third request REQ3 opened, during step S35, a third communication channel between the PGC platform and the voice mail MV.
- the second terminal TC2 has sent a favorable response to the second request REQ2 and the user of the first terminal TC1 is put in touch with the user of the second terminal TC2, communication with the voice mail MV is not finally not necessary.
- Steps S39 and S310 detailed below are implemented in the absence of reception at the level of the platform PGC of a favorable response to the second request REQ2 from the second terminal TC2. This lack of receipt of a favorable response results in either the receipt of an unfavorable response or a total absence of response during the predetermined period of time during which the PGC platform is awaiting a response in from the second terminal TC2.
- step S39 the platform PGC closes the second communication channel between the platform PGC and the second terminal TC2. Indeed, this second communication channel had been opened by sending the second request REQ2 during step S34. Since communication is not possible between the user of the first terminal TC1 and the user of the second terminal TC2, it is not necessary to maintain the telephone call corresponding to the second request REQ2. In the event of failure to receive a favorable response to the second request REQ2 from the second terminal TC2, the platform PGC transmits to the messaging platform PMV, the third request REQ3.
- the messaging platform receives from the PGC platform, via a data channel, a message or API request comprising the voice mail call identifier IAMV associated with said secondary call identifier and a telephone communication request aimed at establishing a communication between the first terminal and the voicemail MV with which the voicemail call identifier IAMV is associated.
- the telephone communication request is for example a request sent according to the SIP protocol.
- this telephone communication request comprises the main call identifier or the secondary call identifier of the second terminal TC2 making it possible to correlate with the API message containing the voice mail call identifier.
- IAMV The primary or secondary call identifier can be inserted in a header of the SIP request, for example in the “Diversion” field of the SIP request.
- the API request contains the call ID of the IAMV voicemail and at least one call ID from the call ID of the first terminal and the primary and secondary ID of the second terminal TC2.
- the PMV voice mail platform correlates the subrequests (API request and telephone communication request such as a SIP request) to determine to which voice mail the telephone communication request should be directed. .
- the correlation is implemented by identifying in the two sub-requests the secondary call identifier of the second terminal TC2 or the primary call identifier of the second terminal TC2. In another embodiment, the correlation between the sub-requests is implemented by identifying the call identifier of the first terminal TC1 (calling terminal).
- the platform PGC connects the first and third communication channels to establish communication between the first terminal TC1 and the voice mailbox MV.
- the user of the first terminal TC1 can then leave a voice message on the voice mail MV associated with the call identifier secondary IAS of the second terminal TC2 and selected by the PGC platform, and not on the voice mail of the primary call identifier IAP.
- This first embodiment has the advantage of that, if the user of the second terminal TC2 refuses or ignores the telephone call corresponding to the second request REQ2, the user of the first terminal TC1 is quickly put in telephone communication with the mailbox. voice MV since the telephone call corresponding to the third request REQ3 is transmitted, in anticipation, at the same time or following the transmission of the second request REQ2.
- the connection between the first communication channel and the third communication channel to allow the user of the first terminal TC1 to leave a voice message is then faster than in the case where this third request is addressed to the voice mail only in l absence of a favorable response from the second terminal TC2 to the second request REQ2.
- the platform PGC receives an incoming call, namely the first request REQ1 from the first terminal TC1.
- This step S41 is identical to step S31 of the first embodiment described above.
- the first request REQ1 can be routed to the PGC platform via the first network RES1, and more precisely via the interactive voice server SVI, so that the PGC platform receives, in addition to the first REQ1, input data characterizing a service required by the user of the first terminal TC1.
- step S42 the PGC platform searches, within the database DB, the main call identifier IAP2 associated with at least the secondary call identifier IAS.
- This step S42 is in fact identical to the step S32 of the first embodiment.
- the platform PGC selects, within the database DB, a voice mail call identifier associated at least with the secondary call identifier IAS of the second terminal TC2.
- This step S43 is in fact identical to step S33 of the first embodiment.
- each voicemail call identifier may correspond to a service.
- the PGC platform can then select, from among the voicemail call identifiers associated with the secondary call identifier IAS, the voicemail call identifier corresponding to the service required by the user of the first terminal TC1 and determined. according to the input data received by the PGC platform.
- the PGC platform During a step S44, the PGC platform generates a second telephone communication request REQ2.
- the second request REQ2 includes the main call identifier IAP1 of the first terminal TC1 and the main call identifier IAP2 of the second terminal TC2.
- the platform PGC sends the second request REQ2 to the second terminal TC2.
- the issuance of the second REQ2 request opens a second communication channel.
- This step S44 is in fact identical to the step S34 of the first embodiment.
- step S45 the PGC platform is waiting to receive, from the second terminal TC2, a favorable response to the second request REQ2.
- the PGC platform is also waiting for a possible unfavorable response from the second terminal TC2, indicating that the user of the second terminal TC2 has refused the incoming call.
- This step S45 is in fact identical to the step S36 of the first embodiment.
- Step S46 is implemented if the PGC platform receives a favorable response to the second request REQ2 from the second terminal TC2.
- step S46 the platform PGC connects the first and second communication channels to establish telephone communication between the first terminal TC1 and the second terminal TC2. Indeed, until this step of the method, the telephone call from the first terminal TC1 was put on hold by the platform PGC, and the telephone call from the platform PGC to the second terminal TC2 was also put on hold. The user of the first TC1 terminal can then enter into communication with the user of the second terminal TC2. Step S46 is in fact identical to step S37 of the first embodiment.
- steps S47, S48 and S49 detailed below are implemented in the absence of reception at the level of the platform PGC of a favorable response to the second request REQ2 from the second terminal TC2.
- This lack of receipt of a favorable response results in either the receipt of an unfavorable response or a total absence of response during the predetermined period of time during which the PGC platform is awaiting a response in from the second terminal TC2.
- step S47 the PGC platform closes the second communication channel between the PGC platform and the second terminal TC2. Indeed, this second communication channel had been opened by issuing the second REQ2 request during step S44. Since communication is not possible between the user of the first terminal TC1 and the user of the second terminal TC2, it is not necessary to maintain the telephone call corresponding to the second request REQ2.
- This step S44 is in fact identical to the step S39 of the first embodiment.
- step S48 the platform PGC sends a third telephone communication request REQ3 to the voice mailbox MV associated with the voice mail call identifier IAMV.
- the third request REQ3 comprises the main call identifier IAP1 of the first terminal TC1 and the voicemail call identifier IAMV of the voicemail MV.
- the transmission of the third request REQ3 opens the third communication channel.
- This step S48 is in fact similar to step S35 of the first embodiment, except that this step is not implemented in parallel or following the transmission of the second request REQ2 to the second terminal TC2. In fact, in this second embodiment, the transmission of the third request REQ3 to the voice mailbox MV is only implemented in the absence of reception at the level of the PGC platform of a favorable response.
- the third REQ3 request is for example implemented via the IP application programming interface of the PMV platform, which routes the third request REQ3 to the voicemail MV thanks to the voicemail call identifier IAMV extracted from the third request REQ3.
- step S49 the PGC platform connects the first and third communication channels to establish communication between the first terminal TC1 and the voice mailbox MV.
- the user of the first terminal TC1 can then leave a voice message on the voice mailbox MV associated with the secondary call identifier IAS of the second terminal TC2 and selected by the platform PGC, and not on the voice mail of the identifier d main IAP call.
- This step S49 is in fact identical to the step S310 of the first embodiment.
- This second embodiment has the advantage of the fact that the transmission of the third request REQ3 to the voice mailbox MV is implemented only if the user of the second terminal TC2 refuses or ignores the telephone call corresponding to the second REQ2 request. This avoids the potentially unnecessary sending of the third request REQ3 in the event that the second terminal TC2 sends a favorable response to the second request REQ2 sent by the platform PGC.
- the present invention has several advantages.
- the invention helps protect the personal information of a user of an alias service and helps maintain their anonymity. Indeed, the selection of a voice mail associated with the alias number and the routing of the telephone call to this voice mail by the communication management platform makes it possible to prevent a person having dialed the alias number from being able to access the telephone. real number voicemail. This is because the primary caller ID voicemail sometimes delivers personal information about the user of the associated communication terminal.
- the first embodiment and the anticipated transmission of the telephone communication request to the voice mailbox allows the user of the calling terminal to be quickly put in telephone communication with the voicemail of the alias number when the user of the called terminal does not follow up on the call.
- the second embodiment makes it possible to prevent the sending of the telephone communication request to the voice mail associated with the alias number from being unnecessarily implemented. Indeed, this request is only sent if the user of the called terminal refuses or ignores the phone call.
- an interactive voice server in the context of the invention makes it possible to improve the routing of a telephone call to a voice mailbox associated with an alias number.
- the input data obtained via the interactive voice server make it possible to determine a service required by the user of the calling terminal and a smarter selection of a voice mailbox not only associated with the alias number but also dedicated to the service in question. .
