CALLS FIELD OF APPLICATION

This descriptive report refers to a RECHARGE AVAILABILITY SYSTEM FOR MAKING PHONE CALLS, through which it will be possible to obtain and redistribute, both totally remotely, a code (pin number) which permits access for recharge for the making of phone calls, which may be used in fixed or mobile telephony. SUMMARY OF THE INVENTION The information and communication technologies have introduced a new reality in the environment in which we live. Currently, the whole world is connected in networks through which flow all available information, which redesign the forms of interaction among people. Analyzing the evolutionary path of the media, one observes a dynamic movement, which departs from vocalization to the written word, passing through the press, by electronic media, to arrive at digital technologies, where one finds dematerialization and hybridization of support.

In a search to improve the interaction among persons, media were developed means that intended to neutralize difficulties that occur in the physical distancing among these people, with view to expand social relationships and/or strengthen already existing ones. Internet, in the past years, was, doubtless, the communication and information media that most evidenced this movement around the globalization of connectivity, to the extent in which, by reducing time and space, it enabled real time connection among the whole world, and, especially, among individuals from different locations. One currently witnesses the rise of another means of communication that incorporates informative and communicative relationship characteristics mediated by Internet, such as interactivity, connectivity, dematerialization and hybridization, and this mean is, unarguably, the cell phone. There is a clear awareness around the person's need to be interconnected, with a change of the focus through which this can be achieved; i.e., what was done by computer before, today is achieved with the use of the cell phone. In fact, the cell phone, by transposing barriers established by time and space, became a device capable of joining people, enabling a nearly permanent connection. It is currently possible to establish, by phone, communications that incorporate several elements of interactions, due to the possibility of voice manipulation, surround sound and image. Cellular telephony began in the 40s, from communication studies, by consummated radio, in the United States; however, mobile telephony was enabled only after the development of low cost microprocessors and digital commutation, which is the digitalization of communication lines of telephone networks. Mobile telephony experiments with devices began in the

United States in 1921 , with an exclusive focus on safety and emergency services, and with few, or almost none, destination for private use. The Federal Communications Commission (FCC), created in the United States, in 1934, in addition to regulate fixed telephony lines, also controlled the radio spectrum, whereas the authorization to create and commercialize communication mobile channels was granted only after World War II. Following the course traveled by this media, in 1947, a high-capacity system was developed in the Bell Laboratories, which made use of several connected antennae, each of which, in its area, would be a cell, hence, the name cellular. The first commercial appliance was created in 1983, and it was quite different from currently known models, both in its external appearance and in its functionalities. DynaTAC 8000X weighed approximately 1 kg, measured 25 cm, was 7 cm wide and 3 cm thick. One year after its creation - 1984 - it became available to consumers, however, the cost of the appliance as well as of the calls was quite high. Since then, cell phones underwent many transformations, which were not limited only to the physical aspects of the same, but reflected mainly on their functions. The digitalization of mobile telephony permitted, immediately, the expansion of the number of lines; however, the incorporation of new facilities was the main transformation brought by digitalization, and, reflecting the tendency to the presented convergence by new technologies, the cell phone started to aggregate in its platform several media, configuring a hybrid mean. Today, cell phones offer e-mail services, news, exchange of multimedia messages, they permit downloading videos and images, taking photos, incorporate customized musical tones, which, in some appliances, reproduce, faithfully, the original sound of songs. This permits that each user, holder of a cell phone, have a multimedia exchange at his fingertips, you just have to connect the device, in a covered area, to enter into the most diverse interactions. Bauman (2004) highlights the fact that cell phones confer upon subjects ubiquity, generating a state of permanent connection among individuals in movement. Therefore, to carry a cell phone means to maintain oneself inserted in a network of potential interactions.

"A message shines on the screen in search of another. Your fingers are always busy: you press the keyboard, typing new numbers to answer calls or compose your own messages. You remain connected - even while you are in constant movement, even if the invisible senders or recipients of the messages received and sent are also in movement, each following his own path. Cell phones are for persons in movement. " (Bauman, 2004, p. 78) Interactions established via cell phone incorporate, to a certain extent, interactivity parameters defined by Pierre Levy, in his book

Cyberculture (1999); namely:

- the possibility of appropriation and customization of the received message , whatever its nature; - reciprocity of communication;

- virtuality, which emphasizes message's calculation in real time, in function of a model and of entry data;

- the implication of participant's images in the messages;

- telepresence. In respect to mobile telephony, it should be emphasized that, upon beginning interactions by cell phone, the user abstracts himself from the space where he finds himself; the involvement with the technology in question is so great that people are as if deleted from the scenario where they are located. Gergen (2002) referred to this phenomenon of absent presence; i.e.: "The individual is physically present, but is absorbed by another technologically mediated world" (GERGEN, 2002, p. 227). The term still refers to the potential interlocutors of cell phone users, which become present due to the possibility of being contacted by phone.

A study conducted by Lee Humphreys (2003), in the United States, tried to analyze the use of the cell phone in public space, seeking to understand alterations provoked from social interaction, based on the notions of public and private. Taking voice services and text messages as a basis, the researcher identified a behavior of privatization of spheres of public space by users in interaction via cell phone. "The cell phone may become a channel to promote the isolation of the immediate environment. (...). This shield of involvement is only a way that subjects have found to create private spaces in order to have conversations by cell phone in public spaces. Most of the time, however, the desire for privacy can be demonstrated through non-verbal. Bodily gestures and movements can indicate the individualization of a collective subject. (Humphreys, 2004, p. 37-8)

Upon analyzing disclosured data by research entities in telecommunications on the penetration of cell phones in several parts of the world, we can affirm that this is one of the most successful technologies of the past 50 years.

According to a recently published report by Anatel (Brazilian Telecommunications Agency), Brazil has more than 67 million active cell phones in operation, conferring upon the country the sixth world position in the rank of mobile telephony, behind only populous and developed countries such as China and the United States. From this amount, 20.25% of telephones are post-paid and 79.75% prepaid. In respect to the used technology , 39.07% of cell phones in service use TDMA technology (Time-Division Multiple Access); 29.67% CDMA (Code-Division Multiple Access) and 30.05% GSM (Global System for Mobile Communication). Analogic technology (AMPS) is still present in 0.37% of the sample; i.e., about 370 thousand appliances in service. In other countries of South America, an expansion in the number of active appliances in operation was also verified; however, the countries of Asia, Western Europe and the United States are the leaders in number of active cell phones in operation. In Finland, for example, there are more cell phones than inhabitants (Puro 2002).

"The Finnish carry their cell phones everywhere, all the time, because they do not want to lose immediate contact. For example, 93% of men and women said that one of the main reasons to acquire a cell phone is to be always available. Contrary to the traditional telephone that is connected to a place, the cell phone is in hands all the time". (Puro, 2002, p. 22).

Departing from an analysis of how cell phones were appropriated by users, it could be verified three types of use made of cell phones. The first is what is referred to safety, where it is not only the question or urban violence that justifies the acquisition of a cell phones by parents, and the fact that they give their children cell phones as a present; the second type are the elderly and/or people with health problems, who see in cell phones the possibility of asking for help or of being attended as quickly as possible in emergency situations. (Ling, 2004), and the third type concerns the coordination of daily activities, where the rhythm of modern life imposes an accelerated routine, and, for a portion of the adult population, both urban and economically active, the cell phone has expanded the possibility of coordinating, long distance, routine activities, and moreover, for many who use cell phones for work, there is an expansion of hours dedicated to the job. If, in the first two cases, the use of the cell phone is instrumental, in the third, it is linked to the need of interaction at any time and anywhere. ANTECEDENTS OF THE TECHNIQUE

It is considered nowadays that a significant portion of users of cell phones choose the prepaid system, due to the most varied factors; however, this system presents as its main inconvenience the fact of requiring periodical recharges, to keep it working, whereas, to attend this need, the user must acquire credits from a point of sale and, starting from the insertion of a code in his appliance, he can then activate it with the operator; however, depending on the place or time when the user is without credit, this alternative of regularization of operationality of his cell phone can become quite difficult or even impossible.

Some systems intended to enable recharge are already known in the state of the technic, remotely, of the credits for cell phone, such as, for example, the system described in the document of Patent PI-0404046-5, which covers the system of remote recharge of prepaid cell phones, via cell phone telephone network, which consists essentially in a remote module that interacts with the system by transactions of messages between the resale of recharges and the operator, so as to permit recharge of prepaid cell phones and management of balances.

The document of patent PI-0401351-4 is also already known in the state of the technic, dealing with a system of recharge of credits in prepaid cell phones, from the appliance itself, by typing a predefined number, through which the user will inform the requested data and desired recharge amount, proceeding, through a program developed for this purpose to transfer funds to the operator, who, in its turn, makes the recharge of the requested telephone credits, passing them on to the user.

It is observed that all the currently existing systems for remote provision of telephone credits are fundamentally based on two conditions that should be attended , the first is the need for the user to make a phone call to the system, which provides a service, which, in itself, can already constitute an unsurmountable obstacle, in the case of the user not having more credit in his telephone; the second is that the user must have a bank account, and a balance in this bank account, to be able to authorize an electronic transfer of funds, bearing the expenses for this service. Another limitation which is noticed in telephone currently known credit recharge systems is linked to the fact that the credit acquired can only be used in the appliance used in the acquisition of the credit, which makes the use of another appliance not viable, if the cell phone of the party interested in the acquisition does not have other credits to make the call. FOUNDATIONS OF THE INVENTION

To the effect of exceeding the inconveniences resulting from current techniques, the RECHARGE AVAILABILITY SYSTEM FOR MAKING PHONE CALLS was created, whose main objective is to provide means for the acquisition of telephone credits, totally remotely, whereas the receiving cell phone will already be after credit transfer, automatically activated before the operator. Another objective of the RECHARGE AVAILABILITY SYSTEM FOR MAKING PHONE CALLS, proposed herein, is to provide means for the cell phone responsible for the acquisition of the credit to be able to request, within a mix of available products, the recharge of its choice and to transfer this credit to another cell phone.

Another objective of the RECHARGE AVAILABILITY SYSTEM FOR MAKING PHONE CALLS, proposed herein, is to provide means for the cell phone responsible for the acquisition of the credit to be able to acquire credits for mobile or fixed telephony.

Another objective of the RECHARGE AVAILABILITY

SYSTEM FOR MAKING PHONE CALLS, proposed herein, is to provide means for the verification of a second or third factor of authentication of the user who accesses the system, through his subscriber account on the Internet.

BRIEF DESCRIPTION OF THE DRAWING

For a better understanding of the present RECHARGE AVAILABILITY SYSTEM FOR MAKING PHONE CALLS, one refers to the attached drawing, where: Figure 1 - Illustrates a block diagram of the serviceability of the system proposed herein. PREFERRED OPERABILITY OF THE INVENTION

The RECHARGE AVAILABILITY SYSTEM FOR MAKING PHONE CALLS, proposed herein, has its serviceability based on the previous registration of the user in the system, through supplying, by any means of remote transmission, of its identification data and of telephone number, cell phone and/or fixed phone, which may be used to acquire credit for making phone calls, whereas these data being received in the Entry Module, returning, through the Message Remittance Module, the information about the conclusion of the successful registration, or the motives for its failure, for its regularization, whereas, once the registration has been completed, the supplied data are transferred to the Database Module, and, afterwards, the system provides, through the Message Remittance Module, means for the user generate a virtual credit in his/her favor, which, after confirmation through the Conciliation Module, will be fed into the Database Module, the user being qualified in the system, to acquire credit for making telephone calls, which may be done by any means of remote data transmission, whereas, prior to the so-called acquisition, the system will use an authentication factor, which will be originated from a call made by the user to the system, through the registered phone , which will be received at the Entry Module, which sends it to the Call Identification Module, where the number of the caller phone is captured, being also identified, by the phone number that was used to establish this connection with the system, the type of recharge that the user wishes to acquire. However, after confirmation of the call originating phone, the user access is authorized , so that the he may inform the quantity of credit that it wishes to acquire, and from then, the Database Module is consulted, which verifies the existence of the type of recharge requested, in the desired quantity, and the virtual credit corresponding to this acquisition. If there is compliance with these conditions, the transaction data are updated in the Database Module, the credits for making phone calls acquired being transferred to the user cell phone. But in each case, if any of these conditions is not met, the Database Module informs this occurrence to the user, through the Message Remittance Module, and, after conclusion of the credits transfer for making phone calls, the code of the credit will appear on the display of the user's cell phone, which code may be passed on, by any means of data transmission, to another telephone number, where, already in the destination telephone, the routines established by the operator responsible for the supply of the credits will be adopted, for activation of the corresponding credit.

The system shall anticipates also, in respect to user's access to the system, other authentication factors, which will always be used from the authentication of a telephone call made by the user through the registered telephone by the latter in the system, which, once authenticated, will open a time window, predefined by the system, for the user then be able to supply through any remote means of transmission of data, its login and password, or any other data requested for its identification in the system, for, after these data were authenticated, the system to authorize or deny his access to the service.

The system also provides a Module for Issuance of Reports, which will supply all the information corresponding to transactions made.
