Description

ASSISTANCE IN THE ESTABLISHMENT OF A TELEPHONE COMMUNICATION BY PROVIDING INFORMATION ON

THE CALLING USER

FIELD OF THE INVENTION

The present invention relates to mobile communication networks. It relates more particularly to the establishment of a communication between two terminals connected to such a network, and a mechanism providing information on the caller to a user of the called terminal.

BACKGROUND OF THE INVENTION

Today, no built-in, stand-alone mechanism is provided to allow a user to have information about incoming calls outside of the caller's phone number that can be displayed on the screen of their own terminal. , and outside the calls of users already known and listed.

Indeed, the communication terminals generally maintain a telephone directory for associating telephone numbers with information sheets that may contain a name, a first name, addresses, and various other data. This directory is personal and allows, during an incoming call, to display the information previously entered in the information sheet associated with this number. Thus, the terminal user will have information on the incoming call.

Such a solution, however, relies on a priori knowledge of incoming calls. It requires a seizure or, at least, a prior registration of an information sheet associated with a telephone number which must, necessarily, be known. It does not display information for a call from an unknown number. In this case, the communication terminal interface will only display the phone number of the incoming call. It is then impossible for the called user to have any information on the incoming call.

It may be interesting for this user to have information on "unknown" incoming calls.

It may also be interesting for calling users to tell users called in advance of the call some preliminary information. This can be particularly the case in the context of commercial canvassing.

It may further be of interest to operators or service providers to provide such service to their customers. Some solutions exist but they are not integrated: the called user must install a particular application, which may not interoperate optimally with the operating system.

Some solutions are not autonomous, because they must be connected to the Internet, in particular to a web server, to be able to function.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a method and a communication terminal at least partially overcoming the aforementioned drawbacks.

The term "communication terminal" is understood to mean devices as diverse as "smartphone" type telephones, fixed telephones, tablets, computers, fixed or mobile computers, and, in general, any electronic device having telecommunication means. he can for example also be embedded devices, especially in the human body, with such telecommunication capabilities.

To this end, the present invention proposes a method for establishing a telephone communication between a calling terminal and a called terminal connected to a mobile communication network, comprising:

a step of reception by said called terminal of a message, and the determination if said message is an information message containing information on a calling user associated with said calling terminal, and in which case, a processing step by said called terminal; said message so as to store said information in a memory of said called terminal;

a step of reception by said called terminal of a signaling message relating to a call from said calling terminal, triggering the search in said memory of information corresponding to said call, and the presentation of second information determined by said information on said called terminal; .

According to embodiments, the invention comprises one or more of the following features which can be used separately or in partial combination with one another or in total combination with one another:

the receiving step includes intercepting said message first to determine whether said message is an information message and, in which case, to process it so that it is not accessible to a called user associated with said called terminal ,

said message is an SMS or MMS message; said message is sent by a server and the method comprises a preliminary step of storing information provided by the user of said calling terminal, by said server; said processing step also includes recovering a visual element from a server from information contained in said information message;

said information message contains a unique identifier of said calling terminal and / or the user of said calling terminal, for example a telephone number, and a second unique identifier, for example a second telephone number, and wherein said called terminal determines said second information by substituting said second unique identifier for said unique identifier;

said information further comprises:

the name and surname of the said calling user;

the name of a corporation or corporation associated with the calling user;

a function of said calling user within this company;

an identifier of a sector of activity;

a visual element;

or a combination of these,

a telephone number contained in said signaling message is substituted for the telephone number of the calling terminal in said call log;

when said called terminal has received said information, it sends an acknowledgment message to said calling terminal;

when following reception of said signaling message, the call is missed on said called terminal (T2), said call is notified in a call log of said called terminal in association with said information corresponding to said call;

the method comprises a preliminary step of storing information provided by the user of said calling terminal within a server, said information comprising a calling telephone number, and a step of transmitting an information message by said server containing said calling telephone, so that the calling telephone is displayed on the human-telephone interface; machine of said called terminal upon receipt of said signaling message.

Another aspect of the invention relates to a computer program comprising software means adapted to the implementation of the method described above, when triggered by an information processing platform.

Another aspect of the invention relates to a communication terminal adapted for receiving a telephone call from a calling terminal through a mobile communication network, comprising:

first means for receiving messages and determining whether a received message is an information message (ma) containing information about a calling user associated with said calling terminal, and in which case, for processing it so as to store said information in a memory of said called terminal;

second means for receiving a signaling message relating to a call from said calling terminal, triggering search in said memory for information corresponding to said call, and displaying second information determined by said information on said called terminal.

According to one embodiment, said first means are provided for intercepting said message in priority to determine if said message is an informational message and, in this case, process it so that it is not accessible to a called user associated with said called terminal.

Another aspect of the invention relates to a system comprising a calling terminal, a terminal as previously described and a server, wherein said server has means for storing information provided by the user of said calling terminal and means for transmitting said information message, containing said information, to said called terminal.

Thus, the invention provides a mechanism for provisioning information relating to a calling user on a called terminal, to assist the user of the latter in the decision to take or refuse an incoming call.

The proposed solution is integrated, and the called user may have no need at any time to install or even configure an application to implement the solution of the invention.

Information messages, which may be of the SMS / MMS type, may not be visible to the user, who therefore does not feel polluted by these types of messages.

The proposed solution also works with a very light infrastructure. It can operate in a territory that does not have a digital infrastructure and that only has a mobile telephony infrastructure such as GSM.

Similarly, if the connection to the Internet is not available, the solution of the invention still allows to proceed to a recognition of the caller.

According to one embodiment of the invention, another advantage is to increase the safety of persons, by allowing official persons to identify themselves clearly, with a technical guarantee, and to limit the possibilities for usurpers to be pass for people from the state or companies on the street to contact individuals or even to break into their home. Thus, a person who must intervene in an individual can announce in advance through the mechanism of the invention by communicating a photograph, for example, or another element of recognition (password ...), which will be displayed on the communication terminal of the individual and will allow him to recognize the person in question when he goes to his home.

Another possible application of the invention is to secure telephone calls as part of the treatment of alerts (fires, earthquakes, etc.). People may be responsible for a geographic area or neighborhood to coordinate actions to be undertaken. The invention can make it possible to enrich and secure calls in order to avoid malicious calls resulting in a loss of efficiency that can have very significant consequences in these emergencies.

Other features and advantages of the invention will appear on reading the following description of a preferred embodiment of the invention, given by way of example and with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 schematically represents an example of a functional architecture of a communication terminal according to one embodiment of the invention.

FIG. 2 diagrammatically represents a communication network making it possible to implement the invention, according to one of these embodiments. DETAILED DESCRIPTION OF THE INVENTION

The invention is based on a mobile telephony infrastructure, allowing the transmission of messages of the type SMS ("Short Message Service") or MMS ("Multimedia Message Service"). Other types of short messages are also conceivable within the scope of the invention. In the following, the term "message" will be used indistinctly the type of messages (SMS, MMS, etc.) used. The invention can be based on a prior step of downloading to a communication terminal a software application for implementing the invention by the particular processing of incoming messages. Preferably, however, this application is installed by default on the called party's communication terminal. It can be an extension of the terminal operating system.

Preferably, it is activated systematically on switching on its communication terminal.

This application contains the software means enabling the communication terminals to benefit from the services provided by the mechanisms of the invention for receiving calls and establishing a telephone communication with a calling communication terminal.

These software means may correspond to the means M1, M2, M3 shown in Figure 1 where they constitute the software application Aa, previously downloaded to the communication terminal called T2.

These means represent functional aspects. Depending on the embodiments, it may therefore be independent software modules, or simply functions or parts of code of the same software module. These means M1, M2, M3 are presented hereinafter as functionally distinct for the sake of clarity. The first means Ml are triggered upon receipt of a message m. Some operating systems define the mechanisms to be implemented by a communication terminal for receiving an SMS message and allow an application to intercept the incoming messages in priority in order to process them. This mechanism can for example allow an application to replace the display application and SMS message processing provided by default by the operating system of the mobile terminal.

This mechanism is especially possible on Android ™ platforms. For example, it is described at the URL:

http://developer.android.com/guide/topics/mamfest/intent-filter- element.html

According to the invention, an information message m called "alpha message", ma, can be received by the communication terminal called T2. This alpha message is a normal message, that is to say complies with the standards of messages of type SMS, MMS, etc.

Below, the invention will be presented in an application to a telephony network, wherein the receiver is identified by a telephone number. Other cases of applications are however possible, such as that of broadcast networks in which the called users are identified by unique identifiers and the information messages are messages of "EMM" type, for "Entitlement Management Message" ".

Its contents distinguish it from other messages of the type SMS, MMS, etc. which should not be processed by the application.

In particular, it can be identified by a particular data to distinguish it from other messages. The role of the means M1 is to determine whether an incoming message m is an information message (m = ma) or not. This particular data can be:

-Identifying it, for example the emission telephone number. In which case, the means Ml have one or more numbers to compare the phone number associated with the message m incoming. For example, they may have a list of phone numbers by country. This list can be hard-coded or configured via an Aa application management server.

- a combination of special characters, "printable" or "non-printable", or "tag". This combination is then recognized by means M1 and allows them to determine by its presence that an incoming message is an "alpha" information message. This embodiment will be described in more detail below, in connection with examples

-a class of SMS;

a private extension of a standard SMS class;

a combination of the possibilities explained above.

The information message comes from a calling communication terminal T1, not shown in FIG. 1, but represented in FIG. 2. This information message is, as will be seen below, potentially a harbinger of a call from the calling user (or sender) of this calling terminal Tl, and aims to improve the experience of the two parties in the communication between the users of terminals T1 and T2.

If the means M1 determine that an incoming message m is not an information message ma, they transmit this message m to the default application TS message processing which can be part of the operating system. Typically, this message m can then be notified on the human-machine interface of the terminal T2. The user of the terminal T2, or "receiver", can display it to read it. If the means M1 determine that an incoming message m is an information message ma, they transmit this message m to means M2 of the application Aa.

Several implementations are then possible. The choice of an implementation can be guided or even imposed by the operating system of the communication terminal.

Indeed, some operating systems do not allow an application Aa to preempt the processing of incoming messages. These will therefore be systematically processed by the default application for processing TS messages. Therefore, the messages ma will be presented to the user of the communication terminal.

In other cases, it is possible and chosen that the application Aa prioritizes the incoming messages and determines itself whether an incoming message must be transmitted to the default application TS messages processing or M2 means .

Since the information messages ma can be presented to the user, they must be formatted to be both relevant to the user and contain information for the M2 means.

A first example of formatting such an information message may be:

-! -

Mr Franck Martin

You will soon be contacted by

Elise Durand,

Company X

Responsible for customer

06XXXXXXXX Such a message can be handled in a meaningful way by the default application of TS message processing. It will be understood by the user of the terminal.

It may contain escape characters, or any other tag (here, the characters "-! -", indicating that it is an informational message ma. Other embodiments are possible to allow the means M1 to determine that an incoming message is an information message ma.

This beacon is understood by the means Ml which can thus process the incoming message as information message ma. The means M2 can analyze the content of this message according to a format decided in advance. This format allows M2 means to determine the locations of expected information (name, company, phone number ...) within this message. This information can then be stored in a memory MEM.

The message of this first example is compatible with SMS services of mobile telephony.

A second example can be:

-! -

Dear Sir Madam

You will soon be contacted by our advisor. Here is his business card:

Business card.vcf

In this second example, the incoming message is of the MMS type. It contains a standard VCF file attachment.

As before, it contains a tag ("-! -", for example) indicating to the means Ml that it is an information message ma. It is therefore transmitted to M2 means that will extract the content of the business card attached vcf and consider it as information to store in memory MEMa.

In these implementations, the information may appear visibly to the users, but the quality of the information message is hidden from them. From their point of view, the information message will appear to me as a simple prospecting message.

According to another implementation, this message will not be available either for the default application of TS message processing, or directly for the user of the T2 communication terminal. It is necessary for this purpose that the operating system and the personalization of the called terminal are adapted to allow the priority processing of incoming messages by an application Aa.

In order to allow compatibility with these two implementations, the information messages may conform to a format as described above. The content will therefore be readable for a user, but the decision to present it to him will depend on the concrete implementation of the mechanism of the invention on the reception communication terminal T2.

In the context of this other implementation, the information messages ma are transparent to the receiver which is not disturbed in its normal use of the terminal T2. The means M1 are therefore adapted so that the information messages are not accessible to the users, in particular by not storing them in the memory provided for the storage of SMS and MMS messages.

The means M2 are provided for storing information contained in the information message in a memory MEMa of the communication terminal T2. This memory is typically a dedicated area of the T2 terminal memory. It can especially be a group of contacts reserved within the telephone directory of the terminal T2.

The information contained in the information messages ma can be stored in whole or in part in this MEM memory. For example, control data, security ("checksum" ...) contained in the information message may not be stored in the memory MEMa. Similarly, the particular data to determine that the message is an informational message may not be stored either.

Whatever the implementation of the mechanism, the means M2 are further adapted to analyze the incoming information message to determine the information it contains. This information can be transmitted in the message alpha ma in a standardized text format, for example of the XML type ("eXtended MetaLanguage") or CSV ("Comma Separated Values") as defined by the RFC 4180 of the IETF (Internet Engineering Task Force).

The information contained in the message ma and that can be stored in the memory MEMa by the means M2 can comprise:

a unique identifier of the calling terminal T1 and / or the user of this terminal (or transmitter), which is at the origin of the information message ma, this identifier is for example a telephone number;

- the name and surname of this calling user;

- the name of a corporation or corporation associated with that calling user (or issuer);

- a function of the calling user within this company;

- an identifier of a sector of activity;

- etc. The activity sector identifier can be used to determine a visual element (logo, graphic, etc.) supplied with the application that will be displayed by default in association with the stored information, when receiving an incoming call from that user, as will be seen later. Other information can also be used to determine a visual element. This can for example be an identifier of a company, etc.

The software application Aa can be provided for connecting to a web server or equivalent, for example, to recover the visual element chosen by the issuer from these identifiers. This visual element can be determined by the means M2 during the reception of an information message and stored in the memory MEMa or by the means M3 when receiving an incoming call.

Thus, one can have a visual element by default, provided with the application, and possibly a visual element downloaded from the web and chosen by the issuer. This second visual element can then replace the default visual element.

According to one embodiment of the invention, it may be provided to allow transmitters to provide graphics, logos, etc. "Default" which will be integrated into all the visual elements provided with the application. This feature can be of interest to large companies, who can pay to have a clean visual element, provided with the application and can be stored in the communication terminal.

As mentioned above, according to one embodiment of the invention, the information message ma is in the MMS format and contains a business card, including a business card, for example conforming to the .vcf format.

According to one embodiment of the invention, the means M2 may be provided for transmitting an acknowledgment message intended for the calling terminal, thereby indicating that it is ready to receive a call from it, that is to say to present to the receiver of information upon receipt of a message from C signaling on his part. It should be noted that this acknowledgment message is intended for the calling terminal but may not be addressed directly to it. As will be seen later, it can be sent to a central server that can act on behalf of the user of the calling terminal T1 (or issuer) and it can then be informed of the acknowledgment via this server.

In a second step, a call from the same calling terminal is received by the called terminal T2. This call can be implemented by a signaling message C, and it aims to establish a telephone call (and possibly video) between the calling terminal and the called terminal T2.

This call is processed by the means M3 of the application Aa. It initiates the search, by means M3, of information corresponding to the incoming call and transmitted by the signaling message C. The search can be based on an identifier of the calling terminal or the sender which can correspond to a key of search within memory MEMa.

Thus, the means M3 can recover the information stored in the memory MEMa in association with this identifier. M3 means can then present to the receiver this information, listed below, so that it can read it before deciding whether or not to take the incoming call, or information derived from the stored information.

As previously seen, this information may include:

a unique identifier of the calling terminal T1 and / or the user of this terminal, which is at the origin of the information message ma, this identifier is for example a telephone number;

- the name and surname of this calling user;

- the name of a corporation or corporation associated with that calling user; - a function of the calling user within this company;

- an identifier of a sector of activity;

etc.

Only a part of the information stored in the memory MEMa can be presented. For example, a name, a company name can only be displayed on the human-machine interface of the terminal T2, at the same time as the incoming call notification.

In addition, a visual element (logo, graphic ...) corresponding to the company or a professional field can also be displayed. As previously described, this visual element may have been stored in the memory MEMa or it may be recovered at the time of this call c depending on an identifier or a link stored in the memory MEMa. This last implementation makes it possible to minimize the volume of data stored in the memory MEMa and to be able to more easily manage the dynamic modifications of these visual elements since these are deported on a server.

The information presented on the human-machine interface of the called terminal T2 can be constructed from the stored information and / or include some or all of the information stored and associated with the identifier of the caller.

Consequently, when an incoming call arrives, the means M3 can conventionally use the memory MEMu which stores the personal directory of the user of the terminal T2, in order to determine if the call comes from a known user. If so, then the information associated with this user is presented to the user, in a manner known per se.

If the user is not known, then a search is triggered in the memory MEMa and if the terminal T2 has previously received an information message from this user, then information can also be presented to the user. . The invention thus makes it possible to present the user with information about a caller, even in the case where the caller is unknown to the user. According to one embodiment of the invention, the memory MEMa is a sub-part of the memory MEMu which contains the directories of the user. For example, a dedicated contact group can be associated with the users corresponding to the information messages and this contact group can be configured so that its contacts can not be visible to the user when consulting his telephone directory.

A mechanism can also be provided to delete certain information stored in the memory MEMa, including the oldest information. These deletions can be triggered according to a date of seniority and / or as a function of a filling rate of the memory of the communication terminal T2 and / or according to a maximum number of users, etc.

According to one embodiment of the invention, the application Aa is adapted to take into account the missed calls. When a call is missed, that is to say not picked up in time by the receiver, the telephone operator notifies in the call log of the terminal T2 that a new message is available, in the case where the sender left a voice message. The application Aa can then complete the content of the notification in the call log by adding additional information such as name, surname, company, and any other information among those stored in the memory MEMa in association with the number of phone the missed call. FIG. 2 illustrates a system embodying the invention, comprising a terminal called T2 as described above, a calling terminal T1 and a server S.

The user of the terminal, or transmitter, T1 provides information to the server S. It can do it through the terminal T1 or by any other means. For example, the server S may offer a web interface for providing this information.

This transmitter provides D information that will be presented to the called user, or receiver. This information D can be provided during a preliminary registration phase of the transmitter Tl with the server S.

This information D may include a personal name, a company name, a type of activity, a visual element such as a logo, a graphic, a photograph, etc. This information can form a kind of virtual business card of the issuer.

Information can be provided automatically, that is, transparently for the sender, such as a phone number of the sender, and so on. This information can be determined automatically by the server S from the signaling data and the communication protocol.

The transmitter may further provide call terminal identifiers to be called T2, for example telephone numbers belonging to a contact list. In one implementation of the invention, the server S itself determines the identifiers of the terminals to be called T2 (for example their telephone numbers) on the basis of a soliciting campaign, or prospecting, configured by the issuer Tl.

The data provided can then be stored in a memory of the server S. This data can be stored in a database set up on the server S. The server S can then transmit the business cards to terminals called T2. It can be a software module executed by the server S which, from the information stored in the server memory, transmits information messages Mi to each identified terminal T2 to prepare the call of the transmitter to that the latter is not anonymous.

Since the information message ma can be accessed by the user, the phone number of the server S may be visible. A specific phone number (or other identifier) may be used, the callback of which will trigger the transmission of a dedicated voice message. This type of number can be provided by the telephone company.

Similarly, the information message ma may be associated with an alphanumeric identifier which will be displayed instead of the telephone number, both when the information message is received and during the consultation of the call log.

A concrete example of this mechanism can be described for a company that wants to carry out a direct marketing campaign with a customer base or potential customers. She then enters the customer files on the server S, including the phone numbers of these customers or potential customers, as well as information about herself: name of the company, type of activity (which will allow the determination of a visual element displayed on the called terminal), possibly a personal or promotional message to "personalize" the call, etc.

Once these data have been entered, the server S can trigger the transmission of an information message Mi to the selected terminals T2 for this campaign of soliciting.

The terminals T2 can transmit, in response, acknowledgment messages Ma. The server S can update the data stored in its memory and present the issuer with an interface enabling it to visualize the base of customers or potential customers and, opposite, if they have received the information message and / or if they have transmitted an acknowledgment message. In this way, the sender knows whether he can trigger a call c to the terminal T2 of the customer with the assurance that his "identity card" will be presented to the customer (receiver). He can decide to wait until a customer or potential customer has received the identity card before calling.

This server can be operated by a service provider that offers this service to memorize the business cards (that is to say the information to be transmitted to customers or potential customers), the customer base or potential customers and to manage the transmissions of business cards instead of the sending user. This service can be offered according to a tariff.

The server can also implement other services, such as the management of "reporting" (data communication) prospecting campaigns or canvassing customers.

According to one embodiment of the invention, a mechanism can be provided to verify that the application Aa is installed on the terminal called T2.

In fact, if the application Aa is not installed on the terminal T2, the information messages ma will not be processed by it but by the default mechanisms of the operating system. The information messages will therefore be considered as normal messages and will appear in the list of messages received for the receiver, which can be considered unpleasant by this receiver.

A preliminary step can be put in place to guard against this problem. This preliminary step consists of transmitting a message to the terminal T2 which is both the least annoying possible if the application Aa is not installed, and which allows the application Aa to react, if it is installed, responding. This message can be transmitted by the server S, and depending on the response or not the terminal T2, it can know T2 terminals that have an application Aa installed.

Such a mechanism can be implemented in different ways.

For example, a message may be transmitted by the server S to the terminal T2 of the receiver, this message containing both a neutral text for the receiver and data for the application Aa. This text may be an informational message from the operator of the server S. In the case where the server S is managed by the operator of the mobile network, this message may be a welcome message on the network.

The data for application Aa may be special characters that are not visible to the recipient. For example, it can be the characters "\ t", "\ n", the character "space" or a combination of these.

When the terminal T2 receives this message, two situations are conceivable:

- the Aa application is installed. In this case the message is processed by the application because, by the presence of the non-visible data, it understands that the message is intended. It responds to the server S to mean it is installed on this terminal.

- The Aa application is not installed. The message is then processed by the default mechanisms of the terminal T2. It is displayed as a normal message and visible by the receiver. An acknowledgment can be sent back to the server S, but according to the normal default mechanisms. The server S will be informed of the non installation of the application alpha Aa by not receiving a specific acknowledgment.

Information on the called terminal can be sent back to the server, with acknowledgment. This information may for example be the operating system, the version of the application Aa, etc. Another implementation may be to issue an operating message, rather than a normal message.

According to one embodiment of the invention, the end user of the service may not be that of the calling terminal. This is for example the case when a company uses a subcontracting call center for a canvassing partner.

In this case, indeed, the call center acts as agent of the user and uses its own telecommunication resources (terminal, telephone number ....). However, the end user wishes to see his own information appear on the terminal called T2, and not those of the mandated call center.

Also, an implementation of the invention provides a mechanism for the substitution of certain information specific to the call center by those of the client user.

Specific information can thus be inserted in the information message m indicating that the transmitter is a call center acting as an agent of an end user.

This specific information may contain an additional telephone number (or other contact information), which is the call center number that will be used to solicit the end user.

The means M2 can process the messages m comprising such specific information in a particular manner, and in particular store in the memory MEMa all the telephone numbers contained in the specific information (that is to say including the telephone number which will be used by the call center to solicit the end user).

When a call occurs, the second means M3 are implemented as described above. In particular, a search is triggered in the memory MEMa, information corresponding to this incoming call and transmitted by the associated signaling message C. If specific information is present in the record corresponding to this call, M3 means then implement a particular treatment corresponding to a call from a call center.

Thus, the means M3 present to the receiver the additional telephone number, instead of the telephone number of the call center.

Also, the additional telephone number is substituted in the call log for the call center telephone number, and the call center telephone number is deleted in the MEM memory.

In addition, an implementation of the invention makes it possible to manage the migration between a previous application Aa and an application Aa deploying the above implementation of management of call centers.

Indeed, this last implementation uses information messages ma modified relative to the insertion of at least one specific information. This specific information can not be understood by an earlier version of the application. The same applies to all new versions of the application implementing new functions impacting the information conveyed by the information messages m.

Also, the application Aa, in all its versions, may be able to understand a particular piece of information that specifies the type of data structure of the message m. Thus, the application Aa will be able to determine if the message m addressed to it can be processed or not, and if so, in what way. If the message can not be processed because it corresponds to a later version of the Aa application, this message can simply be deleted.

In addition, the information message m can be compressed to save bandwidth or, at equal bandwidth, carry more information.

The means M2 are provided to detect whether an information message is compressed and, in this case, to decompress it. Of course, the present invention is not limited to the examples and to the embodiment described and shown, but it is capable of numerous variants accessible to those skilled in the art.
