The invention also enables to trace back data to the server (10).

Description

The present invention relates to a method of communication between an advertiser and users of fixed or mobile telecommunications terminals, and to systems implementing this method.

Currently, the advertising market is organized around several main techniques of consumer approach.

A first technique is global and makes information available to everyone through the media whether it is the public display, the press, broadcasting or television.

A second approach technique is personalized and offers the same information at home or in the workplace, through unaddressed print, direct marketing, telephone or fax solicitation.

These techniques tend to lose their effectiveness, since we observe a significant evolution in consumer behavior, becoming more and more difficult to contact, because more and more mobile.

Document WO 98/49826 discloses a third approach technique, consisting in broadcasting advertising messages during a telephone call between two subscribers to a telecommunications network.

It is clear that this solution is not very comfortable for subscribers, who are disturbed one or more times during their communication. The present invention aims to overcome the disadvantages mentioned above, proposing to use as advertising medium the mailbox assigned to certain telecommunications terminals, storing a message instead of imposing on the user by introducing a possibility of interactive dialogue between the user of such a telecommunications terminal and the message stored in the mailbox assigned to this terminal.

For this purpose, the present invention proposes a method of communication between an advertiser and a plurality of users of fixed or mobile telecommunications terminals and associated with voice boxes, in a telecommunications network, this method comprising steps according to which the advertiser provides to a telecommunications operator or a telecommunication voice server at least one message; the operator or the telecommunications server transmits this message to a voicemail server; the messaging server sends the message to a predefined number of users among the plurality of fixed or mobile telecommunications terminal users, the message being stored in the mailbox of each of these users; and when a user among the aforementioned predetermined number of users consults his voice mailbox, he has the possibility of ignoring message or of dialoguing with the message by means of his telecommunication terminal to obtain information or access a service.

As a non-limitative example, the advertiser may be an advertising advertiser.

The telecommunications server may belong to either the advertiser, the telecommunications operator or a third party.

According to the invention, the aforementioned message can belong to one of several categories. This message can in particular be - either an advertising message, personalized or not, - or a personalized message. The following are non-limiting examples of "personalized advertising messages" and "personalized messages".

For example, an advertisement addressing a user by name and / or having been previously "targeted" according to the tastes, profile or consumption habits of the user may constitute a "personalized advertising message".

As for information containing a personal identification of the user, for example such as a deadline reminder for the payment of an insurance premium, from the insurance company with which the user has subscribed a insurance contract, it may constitute a "personalized message".

In the following, for simplicity, the term "message" refers indifferently all categories of messages mentioned above, unless otherwise stated.

In a first particular embodiment, the advertiser sends the message to the telecommunications server, which in turn transmits it via the operator's network to the mail server.

In a second particular embodiment, the advertiser provides the message to the telecommunications operator, who transmits it directly to his or her mail server (s).

Thus, the present invention makes it possible to reach the consumer more effectively by providing sound messages in his voice mailbox, which the user usually consults frequently and regularly.

In addition, memorizing the messages in the user's voice mailbox, rather than broadcast them during telephone conversations, less restrictive, both for the user, which avoids disturbing, than for the advertiser , which can have messages delivered at any time.

The invention also allows a consumer interested in the content of a message to engage in a dialogue with the message, to learn more about the product or service that is offered to him and / or to provide this product access to this service.

The dialogue between the user and the message is made according to the mode used by the voicemail server. For example, the keypad of a telecommunications terminal can easily serve as an interface for the dialogue between the user and the message by means of DTMF signals (in English <I> "Dual </ I> Tone <I> Multiple < Alternatively, the dialog may implement voice recognition, or any other means recognized by voicemail.

voicemail server can send the message to a predefined number of users with all the users the server is likely to communicate with, except the predefined user group, who do not want to receive any commercial messages, who do not want to receive neither advertising messages nor personalized messages.

This provision confers flexibility to the implementation of the invention and allows the consumer the freedom to choose not to receive advertising messages and / or personalized messages, so that advertising is not imposed on him, which would risk deter some consumers from using this telecommunications service.

In the first embodiment mentioned above, the advertiser provides the telecommunications server, at the same time as the message, with a list of users of telecommunication terminals receiving the message, this list coming for example from a database.

This provision has the advantage of allowing the advertiser to target specific classes of consumers and send them messages adapted to their tastes, their profile, their consumption habits, etc., in order to increase the impact of these messages.

According to a particular characteristic, when he consults his voice mailbox, a user has the possibility of erasing the message, whether or not he has previously listened to this message. This provision helps to give the consumer the freedom to disregard the commercials and / or personalized messages received. In addition, this allows the personalized advertising messages stored in the mailbox to not "clutter" the latter, for messages other than advertising or custom, know, "private" messages, for example from the family circle, relational or professional of the user, can also reach the user of the telecommunications terminal.

According to a particular characteristic, each advertising message or personalized is associated a predetermined life time chosen the advertiser, after which the message stored in a user mailbox is automatically deleted.

As well as the possibility of erasure by the user, this automatic erasure feature makes it possible to avoid overloading voice mailboxes with commercial and / or personalized messages being listened to.

According to a particular characteristic, the life time is transmitted to the users' mailboxes in the form of DTMF signals.

This type of signal is particularly well suited to transmission over a telecommunications network. Any other user-to-user signaling protocol may be transmitted.

In a particular embodiment, the advertiser receives, at regular intervals or not, from the server (s) of voicemail, statistics relating to the operation of messages by users.

This provision allows the advertiser to obtain information on the effectiveness of his mailings and to adapt their content as appropriate depending on the reactions of the recipients.

These statistics may for example include the number of advertising and / or personalized messages stored in a given mailbox at a given moment and / or the proportion of advertising and / or personalized messages deleted by the corresponding user without having been listened to and / or the proportion of advertising and / or personalized messages automatically deleted without having been listened to.

According to a particular characteristic, the advertiser provides the operator or the telecommunications server, at the same time as the message, with data relating to a predetermined date and time at which the message must be sent to the users.

This provision allows the advertiser to schedule the timing of his message, for example by correlating the content of the message at a particular time of the day, or on a particular day of the week, more appropriate for the receipt of such a message. message.

According to a particular characteristic, the mailbox of each of the users is associated with a code, which may for example comprise at least one binary indicator, the value of which is chosen by the user and indicates whether this user wishes to receive advertising messages or not. / or personalized messages.

The user thus has the possibility of entering, for example by means of the keyboard of his telecommunication terminal, the value "1" or "0" of a first binary indicator, according to whether he wishes or not to receive from the advertising, and / or the value "1" or "0" of a second binary indicator, depending on whether he wishes to receive personalized messages or not. These indicators may equally well be in the form of one or more alphanumeric or specific keys of a keypad of the telecommunications terminal.

The user also has the possibility to change his mind and modify the value of these indicators at any time, thus making the use of the advertiser's advertising or personalized messaging service more dynamic.

For the same purpose as that mentioned above, the invention also proposes a voicemail server, adapted to the communication between the advertiser and a plurality of users of telecommunications terminals associated with voice mailboxes, in a telecommunications network. mail server comprising - a receiving module, for receiving, from an advertiser, via a telecommunications operator or a telecommunications voice server, at least one message; and a transmitting module for sending the message to a predetermined number of users among the plurality of telecommunications terminal users, this message being stored in the mailbox of each of the users. For the same purpose, the invention further proposes telecommunications network, comprising a voicemail server as above.

The particular characteristics and advantages of the voicemail server and the telecommunications network being the same as those of the communication method, they are not recalled here.

Other aspects and advantages of the invention will appear on reading the following detailed description of particular embodiments, given by way of non-limiting examples. The description refers to the accompanying drawings, in which - Figure 1 schematically shows the different entities used in the method of the present invention, in a first particular embodiment; FIG. 2 diagrammatically represents the various entities used in the method of the present invention, in a second particular embodiment; FIG. 3 is a flowchart illustrating the successive steps of a procedure for receiving and routing a message according to the invention a messaging server according to the invention up to a mailbox of a recipient of this message in the first embodiment; FIG. 4 is a flowchart illustrating the successive steps of a procedure for distributing a message according to the invention by a mail server to a given list of recipient users, in the second embodiment, where the message is directly deposited by the operator in the mail server and in a particular case where message possibly has a limited life time; FIG. 5 is a flowchart illustrating the successive steps of a procedure for exploitation by the announcer of the responses made by the user when listening to a message; and FIG. 6 schematically represents a voice mail server according to the present invention, in a particular embodiment.

<B> Figure 1 </ B> illustrates the general organization of the method of the invention in a first particular embodiment.

An advertiser 10 is charged by its customers to broadcast a certain number of advertising or personalized messages 12 to a plurality of users of telecommunications terminals 18, either fixed (schematized by letter "T") or mobile (schematized by the letter "M"), through the mailbox of these users.

For this purpose, he may contact a voice mail server 16 of the telecommunications operator to which the network 15 through which the messages will pass will belong.

In this case, the advertiser 10 provides the message (s) to be broadcast to a telecommunications voice server 14, connected to the network 15 of the operator. This connection can be made in the form of a connection via the (Switched Telephone Network), or in the form of a direct connection to an operator switch. The choice of the type of connection is based on economic criteria and is to be negotiated between the manager of the telecommunications server 14 and the operator of the telecommunications network.

It is necessary that the mail server 16 can identify the origin of the messages that are transmitted to it. For this, it implements particular processing in the switch that routes the communication to the mail server. To avoid disturbing the recipient of a message from the advertiser, it does not dial directly his call number, but it simulates a call forwarding to the mailbox of this recipient. For this purpose, the messaging server 16 is associated with the switch (not shown) which, in its analysis tables, carries out unconditional call forwarding to the call number of the voice mailbox of the holder of the telecommunications terminal for any call from the telecommunications server 14 which broadcasts messages from the advertiser. Such a procedure is known because it has already been implemented by operators for "private" messages (of a nature other than advertising or personalized); it will not be described here, especially since its implementation is variable because strongly related equipment used.

Thus, the switch associated with the messaging server 16 sends to the network 15 of the operator, to the messaging server 16, a signaling message of the call, for example in the MIF (initial address message ISDN with User-to-User Facilities) for signaling according to the SSUTR2 protocol (Telephony User Part Version R2) currently used in France.

The signaling message contains in particular the number of the requester (the one identifying the telecommunications server 14), the called party number (the one identifying the mail server 16) and the number called "the first called party" (the one that identifies the recipient to which the type message is addressed, either advertising or personalized, or "private").

<B> Figure 2 </ B> illustrates the general organization of the method of the invention in a second particular embodiment.

As in the first embodiment illustrated in FIG. 1, an advertiser 10 is instructed by its clients to broadcast a certain number of advertising or personalized messages 12 to a plurality of users of fixed or mobile telecommunications terminals 18. , through the voicemail of these users.

For this, the advertiser 10 addresses a telecommunications operator 11, to which he provides the message (s) to broadcast.

In this second particular embodiment, the operator 11 directly transmits the messages 12 to one or more voicemail server (s) 16 with which (s) they are able to communicate telecommunications terminals 18, fixed or mobile, belonging to the recipients of messages, associated with mailboxes. The telecommunications terminals 18 communicate, if necessary, with the messaging server (s) 16 via the network 15 of the operator 11.

The messages 12 are then sent by the server (s) mail 16 to the mailboxes of users, where they are stored for viewing by them.

These messages have the particularity of involving an interactivity between their content and the user. Indeed, they offer the sale of products access to services by calling a response from the user. For example, advertising message may be of the type: "The professional exhibition of tulips is held at the Floralies de Vincennes from March 12 to 14. If you wish to receive his file, press the key" 1 "on the keypad of your terminal, you will receive within 72 hours by carrier or by post, otherwise press the key "2." If you want information immediately this show, call the following phone number: ..., visit site'Web "next: ..." .

Thus, by means of the keyboard of its telecommunications terminal which can serve as an interface, the user dialogs with the message to obtain information or obtain a product or access a service. Alternatively, the user can also dialogue with the message through voice recognition or by any other method, the dialogue mode being a type of mail server function.

Figure 3 details how a voicemail server processes an advertiser's message, that is, a personalized or non-personalized advertising message or a personalized message. This message comes from a telecommunications server and is intended for a user of the mail server.

During a step 20, the mail server 16 receives a message from the network 15 shown in FIG.

In step 22, the mail server 16 determines whether the received message is from the advertiser or not. For this, the mail server 16 analyzes the signaling message described above, received from the network. By comparing the number of the requester with the number of the telecommunications server which broadcasts messages from the advertiser, this number being known to the voicemail service the mail server determines whether a particular message processing is to be performed.

If the message is of an informative or "private" type, that is to say comes from a correspondent of the user who has failed to reach last, in step 24, the mail server applies to this message a conventional treatment that is not the subject of the present invention and which will therefore not be detailed here.

If, on the other hand, the message received comes from the announcer, in step 26, the voicemail server processes the field relating to the first number requested in the signaling message, to determine the number of the recipient's voicemail box, and searches among the users of the voicemail service with which it is connected, the user whose voicemail number corresponds to that contained in the signaling message.

Then, in step 28, the server checks whether the user whose mailbox is supposed to receive the advertiser's message has actually allowed the posting of such messages. For this purpose, the server consults, for example, the value of a binary indicator, to which the user has previously assigned the value "1" or according to whether he wishes or not, respectively, to receive messages from the advertiser. Several binary indicators or alphanumeric or specific keys can be provided to allow more choice to the user in his selection. In this example, if the flag is set to "0," the advertiser's message store is not allowed. An inverse convention could of course have been adopted. Accordingly, in step 30, the message is rejected and in step 32, the server increments by one unit a rejected message counter. The value of this counter may for example be transmitted, at regular intervals or not, to the advertiser, for statistical purposes. If the flag is set to "1", this means that the advertiser's mailing is allowed. In this case, in step 34, the voicemail server controls the inhibition, in the recipient's mailbox, of the greeting message or announcement (for example of the type: 'Your call is routed to voicemail. message after the beep that is of no use here, and the voicemail server directly connects the telecommunications server (ie the advertiser's message server) to the recipient's mailbox for the filing of this message, while adding to the message a specific marking, which will allow the mailbox to recognize the personalized advertising origin of the message filed.It suffices for example 1 bit to encode nature, either advertising or personalized, or "private", the message.

In step 36, once the message of the advertiser has been deposited, the server increments by one unit a counter of commercial or personalized messages deposited, also for statistical purposes, for the advertiser.

The direct deposition of a message by the telecommunications operator in the voicemail server is illustrated by the figure <B> 4, </ B> in the second embodiment illustrated by FIG. 2, in a particular case where the message optionally has a defined lifetime and a so-called partial message repository is desired, i.e. where a predetermined list of message recipient users is targeted.

However, the sequence of steps that will be described applies equally to the direct deposit of a message by the operator in the mail server, to destination, not some mailboxes, but all mailboxes where the Posting of advertiser messages is allowed.

During a first step 38, the messaging server receives, together with a message from the advertiser to be transmitted, a predetermined list of users who are recipients of this message. This list may for example have been established by the advertiser or its customers, based on data they have on the interests and consumption habits of certain users. Thus, the advertiser may choose to send an advertising message to a group of users with similar characteristics whose interests and consumption patterns correspond to the offer that is the subject of this message.

The mail server processes this list iteratively, user by user.

In step 40, the mail server reads the list of recipient users has been communicated to him to determine the first mailbox recipient of the message linked to this list.

The mail server may not perform this step and drop the message in all mailboxes where the message repository of the authorized advertiser.

For this purpose, in step 42, as well as in step 28 of FIG. 3, the mail server checks whether the user of the terminal whose mailbox is supposed to receive the message from the advertiser has actually authorized the filing of such messages.

If their depot is not allowed, in step 44, the message is rejected and in step 46, the mail server increments by one unit a rejected message counter, as well as steps 30 and 32. of Figure 3, respectively. Then the mail server examines, in step 48, whether it has processed the entire list of recipient users or if there are still mailboxes to fill. If the entire list has been browsed, the sequence of operations is complete. Otherwise, in step 50, the mail server looks for the next mailbox to reiterate this sequence.

If, on the other hand, at the end of step 42, it appears that the messaging of the announcer in the current recipient mailbox is authorized, the messaging server proceeds, at step 52, to message and specific marking similar to the operations performed in step 34 of Figure 3. Then, as in step 36 of Figure 3, the mail server increments by one unit, at step 54, a message counter deposited.

In this particular embodiment, a predetermined life time is possibly associated with each message, that is to say that once this time has elapsed, the message is automatically erased in the voice mailbox, whether it has been consulted or not by the user.

Thus, in step 56, the mail server examines whether such a life time is associated with the message it has just filed. If this is the case, at the step the voice mailbox takes into account this life time, for example by setting clock. When the clock reaches a value equal to the life time, it controls the deletion of the message in the mailbox.

During an optional step (not shown in FIG. 5), it is then possible to increment a counter of messages thus automatically deleted without having been listened to by the user.

After taking into account the life time, the mail server performs the step 48 described above, to determine if there are still voice mailboxes to fill, and if so, look for the next mailbox, at step 50.

If the message does not have a lifetime, mail server proceeds directly to step 48 above.

By incrementing the counters of deposited messages, rejected messages and unheard messages, the advertiser periodically receives data enabling him to compile statistics. This list of counters is given as a non-limiting example: it is of course possible to provide other types of meters, depending on the needs of the advertiser.

FIG. 5 illustrates operations implemented by appropriate processing means of the voicemail server, to exploit the user interactivity - message of the advertiser, by analyzing the answers provided by a user while listening to a message. message.

In step 60, the user consults his mailbox and listens to an advertisement or personalized message contained therein.

A convenient interface allowing the user to enter a choice to formulate an answer to a question contained in the message is constituted by the alphanumeric keypad of the telecommunications terminal, pressing a key generating a DTMF signal, transmitted to the advertiser via the telecommunications network for decoding and analysis purposes. In a variant, the DTMF signals transmitted to the keyboard by the user can be decoded and analyzed by a calculation unit in the voice mailbox, and transmitted to the announcer in the form of a "plaintext" report.

However, interactivity using DTMF signals is only one example; other techniques, such as voice recognition, can be used.

It is assumed in this example that the mailbox has received a message calling from the user a choice between two possibilities to enter the keyboard by pressing either the key or the key A step 62, the mailbox calculation unit first tests whether the DTMF signals sent by the user correspond to an erase code of the message.

If this is the case, in step 64, the calculation unit controls the deletion of the message and, in step 66, the incrementation of an erased message counter unit.

If the transmitted DTMF signals do not correspond to an erasure code, the calculation unit of the voice mailbox tests, in step 68, whether these signals correspond to a first predetermined code, generated for example by pressing the " 1 "from the keypad of the telecommunications terminal. If it is the code "1" that has been sent, the computing unit writes the number of the mailbox considered in a file intended to list the users who answered in step 70. The code "1" for example, a positive response to a proposal to send product documentation.

If the transmitted DTMF signals correspond neither to an erasure code nor to the answer "1", the calculation unit tests, in step 72, whether these signals correspond to a second predetermined code, generated for example by press the "2" key on the telecommunications terminal keypad.

If this is the case, the computing unit writes the mailbox number considered in a file intended to list the users who answered "2" in step 74. The answer "2" corresponds for example to an answer negative to a proposal to send product documentation. If the transmitted DTMF signals do not correspond to an erase code, neither to the answer "1" nor to the answer "2", the calculation unit sends an error message to step 76, indicating that user entered code is invalid and inviting the user to enter another code on the keyboard.

Figure 6 shows in block diagram form the simplified overall structure of a voicemail server 16 such as that mentioned above.

 messaging server 16 includes a receiving module, which receives messages 12 from the advertiser 10, via the operator 11 or the telecommunications server 14.

Messaging server 16 also includes transmitting module 82, which sends the message 12 of the announcer 10 to the telecommunications terminals 18 of certain users, as described above, so that messages 12 are stored in the associated mailboxes. transmission module 82 may include a sorting unit (not shown), which allows messages to be sent to only certain users, namely, those which allow the reception of messages from the advertiser.

transmit and receive modules 80, 82 may form a single unit.

moreover, a calculation unit 84 is connected to the transmission and reception modules 80, 82 and generates statistics relating to the operation of the messages by the users.

The sending module 82 then returns these statistics to the advertiser.

 As described above, by way of non-limiting example, the statistics computed by the calculation unit 84 may comprise the number of advertising and / or personalized messages 12 stored in a given mailbox at a given instant, and / or the percentage or proportion of advertising and / or personalized messages deleted by a user without having been listened to and / or the percentage or proportion of advertising and / or personalized messages automatically deleted without having been listened to, or any other operating statistics data deemed useful the advertiser.
