Abstract

The electronic messaging system comprises a central memory (2) comprising memory areas (20) addressable by call codes (CAP) and containing information messages (MS). These different call codes are transmitted on a radio-frequency carrier (4) towards the radio-frequency receiver (5). The address information of these receivers comprises a fixed zone and a zone which can be defined by the user according to the type of message he wishes to receive. In the event of a match between a call code and address information, a match signal is sent to the receiver. The call code received, and having given rise to a match, is then transmitted acoustically to a voice server (6). This extracts the received call code from the acoustic signal and broadcasts the entire corresponding message into the user's telephone handset (7).

Description

I

  Interactive electronic messaging system.

  The invention relates to interactive electronic messaging.

  Currently, when an organization, a chain of stores or a service provider wishes to disseminate for example promotional information intended to be bought by potential customers, these must publish a certain number of advertising prospectuses or catalogs which they then make broadcast for example in

  the mailboxes of potential customers.

  Such a process is generally tedious to implement, costly and does not always guarantee to be able to contact all the potential customers likely to be interested in at least one of the

promotional products.

  The invention aims to propose an interactive electronic messaging system, making it possible in particular to remedy the drawbacks which have just been mentioned, and which, in general, makes it possible to put in contact different entities, for example shops and their

  potential customers, without resorting to the distribution of paper-based media.

  In addition, the messaging system according to the invention is interactive in the sense that it is the entities intended to receive messages which themselves define the types of messages which they wish to obtain. In other words, the invention aims to allow filtering at

level of information received.

  To achieve these objectives, the invention proposes a messaging system essentially comprising radio-frequency receivers intended to receive information messages, for example to be "informed" of the various promotional offers, which have been

  centralized in memory means.

  However, a very important problem inherent in such electronic mail lies in the possible saturation of the wireless transmission network and in the need to provide significant memory means to possibly store a very large number

information messages.

  The invention notably solves this double problem by providing for the transmission, not of complete information messages on the radio network, but by transmitting only call codes associated in a one-to-one manner with these information messages, and in deporting the memory necessary for the content of information messages in the centralized memory means. In other words, the invention thus minimizes in particular the amount of memory required at each radio frequency receiver, and consequently the silicon surface used, which has an impact.

  direct on the manufacturing cost.

  The invention therefore proposes an interactive electronic messaging system comprising: - main memory means comprising memory areas each containing an information message and each addressable by a chosen call code, - radio transmission means - frequency comprising means capable of extracting said call codes from main memory means, and transmitting on a radio frequency carrier call information containing respectively said call codes, - a plurality of receivers of said carrier, comprising each a first memory capable of containing at least address information of the receiver, and

- at least one voice server.

  Address information of a receiver comprises a first zone, the content of which cannot be modified by the user of the receiver, and a second zone, the content of which is defined on the initiative of this user. Each address information thus defined then contains a user code comparable to a call code, that is to say having for example a structure identical to that of a call code. The receiver also contains a first interface allowing the introduction of the content of this second zone. Processing means are also provided capable of comparing each received call information with said address information and a second interface capable of delivering outside the receiver a match information in the event of a match between at least one piece of information. call and at least address information taking into account predetermined criteria of concordance between a call code and a user code. The receiver also contains a second memory capable of storing the call code of any call information which gave rise to a match and restitution means capable of restoring acoustic restitution information comprising, preferably an identifier, to a telephone set. receiver, and the

  call code contained in each stored call information.

  According to the invention, the voice server is connected to the telephone set and to the main memory means. This voice server is able to receive the acoustic restitution information, to compare each call code contained in the restitution information with said call codes contained in the main memory means and to deliver the content to the telephone set. information messages corresponding to each of the call codes contained

in the restitution information.

  In other words, the user of a radio frequency receiver determines for himself the types of messages he wishes to receive, for example promotional offers which he wishes an entity, for example a store, to make him part, by determining itself part of the address information of its receiver. Of course, if this user is interested in several different promotional offers, he will then define several different address information for the receiver. Only the call information which has given rise to a match with this stored address information will be signaled outside the receiver, for example by an audible signal emitted by a piezoelectric plate transducer or by an electroluminescent diode. The user will then be notified

  that an article whose characteristics he has defined is available.

  To know the complete characteristics of the offer, the user then picks up a telephone handset, dials the call number of the voice server connected to the main memory means and has the call codes that gave rise to restored in acoustic form. concordance in its receiver. The voice server, upon reception of this acoustic signal, extracts the call codes therefrom and then communicates via the telephone line the complete information messages designated by these call codes and stored in the main memory means . The user then becomes aware of these complete messages via the

  speaker of his telephone handset.

  The invention also relates to a method for interactive transmission of information messages by radio frequency carrier and telephone signals, in which the information messages are stored in memory areas of main memory means each addressable by a code of selected call, call information containing respectively said call codes is transmitted on a radiofrequency carrier capable of being received by a plurality of receivers, at least one address information of the receiver comprising a first zone is introduced into each receiver with content that cannot be modified by the user of the receiver and a second zone with content that can be defined on the initiative of said user, each address information thus defined containing a user code comparable to a calling code, one compares within each receiver each call information received with each address information, we deliver to the outside of the receiver a e concordance information in the event of concordance between at least one call information and at least one address information taking into account predetermined criteria of concordance between a call code and a user code, it is restored to a connected telephone set to a voice server connected to the main memory means, an acoustic restitution information item comprising the call code contained in each call information item having given rise to a match, each call code contained in the voice server is compared at the voice server level. restitution information with said call codes contained in the main memory means and the content of the information messages corresponding to

  each of the call codes contained in the restitution information.

  According to one embodiment, the content of the second address area of each address information is introduced from an acoustic activation signal transmitted by the voice server to the receiver via the telephone set. , this activation signal being developed within the voice server in response to user indications transmitted to the server via the

a phone booth.

  It is also possible to introduce the content of the second address zone of address information by means of a keyboard arranged on the receiver. Other advantages and characteristics of the invention will appear on examining a non-limiting embodiment and the accompanying drawings, in which: - Figure 1 is a schematic block diagram of a messaging system according to the invention;

  - Figure 2 is a schematic block diagram of a radio receiver

  frequency of the system of FIG. 1; - Figure 3 schematically illustrates a call code designating a message recorded in main memory means; - Figure 4 schematically illustrates address information defined within a radio frequency receiver; and FIGS. 5 and 6 illustrate in more detail a particular mode of transmission of acoustic information over a telephone line

  between a receiver and a voice server.

  As illustrated in FIG. 1, the messaging system 1 according to the invention comprises radio frequency transmission means 3 connected to main memory means 2, for example a file, comprising memory areas 20 each addressable by a CAP call code and containing an MS information message. In practice, the transmission means 3 and the main memory means 2 can be physically combined within the same station or else

  be connected by conventional data transmission means.

  The transmission means 3 transmit a radio frequency carrier 4 towards a plurality of radio frequency receivers 5, one of which

  only one of them is shown for simplicity.

  Each radio frequency receiver 5 is able to cooperate with the handset 7 of a telephone set connected to the telephone network

switched 8.

  On this switched telephone network 8, a voice server 6 is also connected, also connected also to the main memory means 2. Here again, the voice server can also be grouped together.

  within the station comprising the main memory means.

  The transmitting station 3 comprises, conventionally, station coding means, not shown here for the sake of simplification, intended in particular for producing the radio-frequency carrier. The invention is not limited to a particular standard of radio frequency transmission. Thus, when using the RDS transmission standard, well known to those skilled in the art, these station coding means include in particular an RDS coder such as that described in European standard EN-50067, for example the version of December 1990 (Cenelec-Bruxelles, reference EN-50067: 1990 E). Of course, the station 3 also also conventionally comprises an HF transmission stage connected to an antenna. It is also possible to use as transmitter 3, in particular on French territory, the transmitter FRANCE-INTER kilometric wave of Allouis which diffuses at 162 KHz time signals coded in phase modulation at the speed of l bit / second . These time signals occupying only 300 ms / s, the organization called Center Commun d'Etudes de Télédiffusion et Télécommunications (CCETT) has developed an extension of the modulation system thus allowing an additional 25 bits to be transmitted every second in the interval between 0.7 seconds previously unused, while remaining compatible with existing time receivers. In other words, the information transmitted according to the invention between such a transmitter and the receivers 5 would then be broadcast according to this modulation system in this interval of 0.7 seconds. It is not necessary to describe here in more detail the characteristics of this data dissemination, which are well known to those skilled in the art. The latter may nevertheless refer for more details to the review of RADIODIFFUSIONTELEVISION n 95-1986,

pages 1-9.

  Similarly, for the same transmission standard, for example the RDS standard, there are generally several different networks including

  some may not be used.

  Furthermore, in general, the messaging system according to the invention is intended for several providers, for example service companies offering the dissemination of stock market information, chain stores offering the dissemination of promotional offers, or else credit companies in relation with several chain stores, concert halls, travel agencies, amusement parks, ... Likewise, at least some of the providers can provide several different services. Thus, for example, a stock exchange service company may offer information relating only to stocks in general, or to specific stocks of certain companies, or only to bonds, or so

  information on foreign exchange markets.

  Likewise, a credit company can offer information messages in connection with different sectors, for example the automobile sector, the furniture sector, shows,

trips, ...

  We will now assume in all that follows that the messaging system according to the invention comprises only one voice server 6 linked to a central file usable by all the service providers.

  and for different transmission networks.

  The call code CAP (FIG. 3) identifying an information message MS is then advantageously composed of several digits, for example A1-A12. Those skilled in the art know that two digits, which vary from 0 to 9, can be coded in binary notation

decimal coded (BCD) with 7 bits.

  The first two digits A1 and A2 are then for example representative of the transmission network used. The next two digits A3 and A4 designate the service provider. The next two digits A5 and A6 designate a particular service offered by the service provider. The other digits, namely here the digits A7 and A12 complete the call code CAP and make it possible, for example, to refine very precisely the various products targeted in the service offered. Thus, if for example the digits A5 and A6 are representative of the furniture sector offered by a chain of department stores, it is conceivable that the digits A7 and A8 make it possible to distinguish in this sector, the sub-sectors relating more particularly to the bedrooms , bathrooms or kitchens, while digits A9 and A10 will be more focused on different types of furniture, for example cupboards or shelves, while digits All and A12 will be used to codify price information. Thus, suppose that a chain of department stores makes a promotional offer on cupboards for bedrooms and that its message of information consists not only in clearly indicating such a promotion, but also the address of the store and the days during which this promotion is effective. The corresponding MS information message will be preceded by a CAP call code

  whose two digits A7 and A8 will have values predicted for the sub-

  bedroom sector, while the two digits A9 and A10 will have the values corresponding to the values provided for the cupboards, while the last two digits All and A12 will take

  as values, those provided for a price below 5000 Frs.

  Of course, the different call codes vary depending on the service providers and the different messages offered, and are stored in the memory means by means of processing means.

classics.

  In the example which is described, providing for single main memory means and a single central server, the call information intended for the various radio-frequency receivers is in fact the CAP call codes. In practice, the transmission means 3 comprise means, for example a computer, capable of scanning the content of the main memory means so as to transmit, in

  general periodically, all of these CAP call codes.

  Before examining their processing at the level of each receptor, we will now describe with particular reference to the

  Figure 2, the internal structure of such a receiver.

  To the reception antenna 50 is connected a conventional high-frequency reception stage 51 delivering the received carrier to separation means, not shown here for the sake of simplification, and which can conventionally be an RDS decoder such as that described in European standard EN-50067 (if this transmission standard is used). Processing means 52, functionally produced in software form and installed in a microprocessor, or else hardware produced by a specific integrated circuit (ASIC), are

connected to floor 51.

  The processing means 52 are conventionally associated with a first random access memory 55 capable of containing one or more address information IAD which will be discussed in more detail on the

structure below.

  A second memory 57 is also connected to these processing means 52, in practice a random access memory, itself connected to restitution means comprising an activation member 58 connected to coding means 57 and an electro-acoustic transducer 59, for example a buzzer. As will be seen below, these restitution means make it possible to restore restitution information

  acoustic outside the receiver.

  Similarly, as will be seen below, each IAD address information item in fact comprises a first zone whose content is predetermined and cannot be modified by the user and a second zone whose content is defined by the user of the receiver. . In practice, the content of the first zone is housed in a memory 502, preferably rewritable, which moreover contains an identifier SN of the receiver, for example its serial number. Also, there is provided a first interface with this user, allowing the latter to introduce on his own initiative, the content of the second address zone into the receiver. This first interface may consist of reception means 500, for example a microphone, intended to receive acoustic activation information comprising the content of the second address area of address information, and extraction means 501 intended to extract from this information the content of the second address zone in order to deliver it to the means of

treatment 52.

  However, it can also be planned to use as a first

interface a keyboard 56.

  Finally, in order to signal to the user of the box a concordance between received call information and address information of the receiver, there is provided a second interface which may include another electro-acoustic transducer 54, for example a piezoelectric blade and / or a light emitting diode, and / or a screen

display 53.

  We will now describe in more detail the operation of the

  messaging system on a particular example.

  It is assumed that a user decides to obtain a radio frequency receiver from a service provider, for example a chain of department stores, and that he is more particularly interested in the furniture sector. It is also assumed that this receiver is intended to operate on a particular network using a certain standard of transmission. The receiver will then include in the memory 502 indications representative of the designation of the transmission network used, of the designation of the service provider.

  service considered, and the designation of the service or sector concerned.

  These indications, illustrated by the digits D1-D6 in FIG. 4, form the first address zone Z1 of address information IAD, and are written to memory 502 when the receiver is delivered to the user. So that the user can precisely define the types of offers or types of message of which he wishes to be informed, it is then advisable for him to complete the address information of his receiver with a second address zone Z2. To do this, several solutions are possible. According to a preferred embodiment allowing an easy update of the content of the main memory means, the voice server comprises production means 60, 61, for example produced under

  software form, and a piezoelectric blade 62 (electro-

  acoustic), capable of developing, in response to user indications transmitted by the user via the telephone set, the content of the second address zone of each address information item under the

  form of acoustic activation information.

  More precisely, the user picks up his telephone handset, dials the call number of the voice server and initially transmits the indications contained in the first address zone, namely the digits D1 to D8. This transmission can be done in different ways. It can be carried out, in response to questions sent by the voice server, by actuating specific keys of the telephone set, or else by means of acoustic reproduction means 57 to 59 of the receiver. The voice server also comprises means, produced conventionally in software form, then making it possible to question the user in order to ask him for his various choices. These choices, which are also materialized by actuation of keys of the telephone set, make it possible to transmit signals to the voice server which are in fact the user indications which the microprocessor 60 will use to develop the digits D7 to D12 of the second zone. address information of receiver address

(figure 4).

  These digits are then transmitted in the form of acoustic activation information, via the telephone line to the user's telephone set 7. The latter then places the microphone 500 of its receiver on the loudspeaker of the telephone handset and the extraction means 501 are then able to extract from the activation information received the content of the second address zone of

address information.

  The processing means 52 of the receiver then define, from the first address area composed of digits D1 to D6 and from the second address area composed of digits D7 to D12, the address information of the receiver corresponding to the wish of the user. This address information is stored in memory

long live 55.

  This IAD address information therefore constitutes here a code-

  user who will be compared to the different call codes received by the receiver. This user code is here distributed between the first and the second address zones Z1, Z2. In the first address zone, the ZZ1 sub-zone corresponds to indications designating the type of transmission network, the ZZ2 zone contains the indications designating the service provider, while the ZZ3 sub-zone contains indications relating to the service user to which the user has subscribed. The second address zone Z2, the content of which is defined by

  the user, contains, in the example illustrated here, a first sub-

  ZZ4 zone corresponding for example to the bedroom sector, while the second ZZ5 subzone defines the area of cupboards inside this sector and that the third ZZ6 subzone

  refers to a price indication.

  Concretely, we can for example assume in this example that the user, who has a receiver delivered by a chain of department stores and who has subscribed to the furniture service, wishes to be notified of offers to sell bedroom cabinets born

not exceeding a certain price.

  Of course, if the user wishes to be informed of the existence of other promotional offers, he can repeat the operations described above so as to define other information

  IAD address which will also be stored in memory 55.

  When the transmission means 3 will deliver on the carrier 4 all the call codes contained in the main memory means, the processing means 52 of the receiver will compare each of these received call codes with each of the information

  address stored in the RAM 55 of the receiver.

  In the event of an identity between at least one of the call codes received and at least one of the address information, the call codes received which gave rise to such a match will be stored in a

RAM 57.

  Furthermore, in order to warn the user of the occurrence of such a match, provision may be made for the transducer 54 to emit a specific sound or else for a light-emitting diode to light up on the receiver. One can also provide, when the receiver is

  provided that a written indication is displayed on the screen 53.

  From this moment, the user will then activate the activation member 58 of the restitution means and these will deliver via the electro-acoustic transducer 59, outside the receiver, a acoustic restitution information containing not only the various call codes stored in memory 57,

  but also preferably the identifier SN of the receiver.

  The user places his receiver against the microphone of the telephone handset 7 which has previously been used to call the voice server. The processing means 60 of the latter then extract from this acoustic restitution information received, the various call codes and compare these with those which are stored in the main memory means. The voice server then delivers the corresponding complete messages to the user via the telephone line. The user can therefore take cognizance of all the information corresponding to his choices by

  through his telephone handset.

  It should be noted that the identifier of the receiver is advantageously transmitted at the same time as the call codes so as to be able to identify the potential customer and subsequently send him eventually an order form or any other additional information. We have just mentioned, as a criterion of concordance giving rise to the emission of information of concordance on the receiver, a

  perfect identity between a call code and address information.

  As a variant, it can be foreseen that these criteria of concordance also include the reception of call information, the

  call code includes a specific predetermined data.

  More specifically, a chain of stores can express the wish to warn its potential customers of an exceptional promotion in a particular sector, even if they have not expressed the wish. It can then be provided that some of the digits A1-A12 of a call code are forced to specific values and that any receiver whose processing means detect the presence of such digits, transmit the concordance information (although there is not perfect equality between the call code thus received and the address information or information stored by the user in his receiver) and store this specific call code in the memory 57. Thus, when the user will activate the means of restitution of his receiver, he will automatically take cognizance of the corresponding information message. It is also possible to provide that the second address area 72 of an IAD address information item is capable of containing configuration data (D13 in FIG. 4) and that the processing means 52 of the receiver are then able to define a additional criterion of concordance between a call information and this address information as a function of the meaning of this configuration data. Concretely, we can perfectly imagine that a user has set a maximum price indication in the ZZ6 subzone of the second zone of his address information (digits Dll, D12), but that he nevertheless wishes to be warned of an offer of a product similar to the one chosen but whose price differs slightly from that indicated in the ZZ6 subzone. In this case, provision can be made for digit D13 to be representative of a price range. Thus, upon reception of a call code whose digits Al-A10 correspond to digits D1-D10 of the address information but whose digits All and A12 differ from the digits Dll and D12 of the information of address, the microprocessor 52 will nevertheless determine whether the price indication designated by the digits All and A12 of the call code CAP corresponds to the price indication designated by the digits Dl l and D12 of the information

  address given the presence of digit D13.

  If this is the case, then information will be sent

  match and the received call code will be stored in memory 57.

  In all of the above, it has been assumed that there is only one voice server and only main memory means. In this case, the transmitted call information is advantageously the CAP call codes making it possible to address the memory areas 20 of these main memory means 2. However, it is perfectly conceivable that for a certain transmission standard, there is n There is only one transmission network and each service provider has its own main memory means and its own voice server. In this case, only the digits A5 and A6 designating the different services offered by the service provider are in theory useful (in addition to the digits A7 and A12) for addressing the different memory areas. In other words, it is conceivable in this case that the call code CAP is reduced to the digits A5-Al2. However, in order to ensure that a receiver delivered by this service provider only receives messages delivered by this service provider and not by another provider, the call information transmitted will include, in addition to the call code, digits Al-A2 designating the transmission network and digits A3 and A4 designating the service provider. These digits A1-A4 then constitute here predetermined call indications. In this case, the concordance criteria at the level of each receiver furthermore include an identity between the call indications A1-A4 of each call information received and indications contained in the first address field of each information.

  receiver address, in this case the digits D1 to D4.

  In other words, if there is no equality between the digits A1-A4 and the digits D1-D4, there is no transmission of concordance information and there is no storage of the call code received in the

memory 57.

  These indications contained in an address zone which cannot be modified by the user ensure, in particular for service providers, electronic security against any fraud or misappropriation of messages by

rogue users.

  It is also possible in other embodiments, for the user to define the content of the second address area of each of the address information of his receiver other than by using a voice server. He can in this regard, for example use the keyboard 56 of his receiver and compose the different digits of the second address area on this keyboard from a catalog provided by the service provider (s) and containing the list of all the

possible call codes.

  As a variant, and in particular in the case where all of the possible call codes are not too large, provision may be made for the receiver to include an additional memory, for example a read only memory (not shown in the figures for the purposes of simplification), capable of containing the list of all possible call codes, and that the processing means 52 of the receiver are then able to define the second address area from information from

  command entered by the user using the keyboard.

  Concretely, the microprocessor 52 can contain software capable of defining questions for the user, questions appearing on the screen 53 and inviting this user to define his choices in him.

  proposing to operate this or that key on the keyboard.

  We have mentioned above the possibility of transmitting on the telephone line acoustic restitution information and / or acoustic activation information. It is therefore particularly advantageous, in particular in order to avoid disturbing the transmission of the data with parasitic frequencies, to use a coding of

  restitution and / or activation information in the form of a code-

  acoustic bar. Concretely, coding means are provided, which can be implemented in software form within a microprocessor, both in the server and in the receiver. These coding means are capable, for a bit of logic value "1" of the acoustic information transmitted, to deliver a logic signal having a high state for a first predetermined duration and a low state for a second predetermined duration. On the other hand, for a bit of logical value "0", the coding means deliver a logic signal having the low state for

  all of the first and second durations.

  In combination, the transducer 59 or 62 will not deliver any acoustic signal in response to a logic signal in the low state, and, in response to a logic signal in the high state, will deliver a single frequency acoustic signal whose frequency is substantially at

  center of the telephone line's bandwidth.

  A frequency of 2048 Hz will therefore preferably be used, which is moreover easily usable from a conventional 4-bit microcontroller, since this frequency is a multiple of two. The logic signals S1 and S2 corresponding to bit codings having logic values 1 and 0 respectively, are illustrated in FIG. 5. The total duration T of transmission of a bit is 15.625 ms, which corresponds to approximately three times the time constant of a carbon microphone fitted to a telephone set. With regard to the signal S1, the duration Tl during which the logic signal is in the high state, is taken equal to 11.71875 ms, while the duration T2 is equal to 3.90652 ms. In fact, only the mask of the signal S 1 is shown for the purposes of simplification in FIG. 5 and we will nevertheless speak of a high state for the signal S1 for the duration T1 although in reality, during this duration, the

  signal consists of a plurality of peaks at the frequency of 2048 Hz.

  This transmission time of 15.625 ms, corresponding to a transmission speed of 64 baud, was adopted here because of its ease of implementation. However, it is possible to choose an optimal transmission speed between 15 baud and 16 baud, which makes it possible to obtain a stable transmission signal taking into account the

  time constant of a carbon microphone.

  Data transmission takes place by sending successive frames. The reception, at the server and / or the receiver, is then of synchronous type, that is to say that there is a synchronization carried out on the header of each transmitted frame. This synchronization allows in particular the adjustment of the reception levels by an automatic gain control device, the detection of the transmission speed, and the setting of the reception means. The adjustment of the reception level by an automatic gain control device allows good reception of the frames and compensates for the loss of the levels due to the carbon microphone (if used), or by means

  amplification of a signal produced by an electronic microphone.

  A transmission frame is illustrated in FIG. 6. The duration of the header of a frame is 575 ms and is broken down into a logic signal S3 in the high state for a duration T3 of 400 ms maximum, allowing control automatic gain, followed by a signal in the low state S4 for a duration T4 of 50 ms allowing the setting of the reception means of the server and / or the radio-frequency receiver, finally followed by a synchronization byte S5 comprising alternating bits 1 and bits 0 for 125 ms. The signals S1 and / or S2 corresponding to the restitution (activation) information are

then transmitted.
