Full Description:
BACKGROUND OF THE INVENTION 
       [0001]    This disclosure relates generally to methods and systems for gaining access to networks such as the Internet and other wide area networks (WANs), and more particularly to methods and systems for gaining access to networks within a local area made available by a commercial establishment within a local area. 
         [0002]    Network users access so called wide area networks, such as the Internet, using different methods. The term “network” is used herein to refer to any local or wide area network; the Internet, intranets, and so on. Most users access a network by obtaining an account with an Internet service provider (ISP). In this case users are generally provided with a user name and password. Each time such a user accesses the network, his user name and password is provided to the ISP to validate the user. Typically, the user name and password is communicated in the background and the user never sees the transmission. Users also gain access to a network at their place of employment by logging on to a company intranet. In both of these cases network access is controlled. 
         [0003]    There are times where a user would like access to a network when not at home and not at work. In this case users generally must access the network in a public venue such as a hotel room, airport, coffee shop, designated public area, trade show, or any other venue that may offer network access. In these situations the user typically does not have an account with which to access the network. In some instances a venue offers network access without charge by simply making the network signals available to anyone without requiring a username and password. However, more often than not a service provider controls network access at a public venue. For instance, T-mobile and Boingo are examples of companies that control many “Hot Spots,” or areas that have Wi-Fi® access. In such instances, if a user is a member of the T-mobile network, for example, then the user can access the network with a T-mobile user name and password. If a user is not a member, then the user can subscribe or purchase a one time usage. In these cases the relationship is between the user and the access point provider or service provider. 
         [0004]    Unfortunately, the venue owner may be unable to exercise control, if desired, over network access in such instances.

Therefore, it must be understood that what is illustrated is set forth only for the purposes of example and that it should not be taken as a limitation in the scope of the present apparatus and method of use. 
       DETAILED DESCRIPTION OF THE INVENTION 
       [0034]    A location or venue includes a configuration in accordance with aspects of the invention as in  FIG. 1 . In various embodiments the location or venue may be a retail environment, designated public area, hotel room, trade show, restaurant, coffee shop, bookstore, airport, bus, subway, airplane, ferry, ship, train, sports stadium, mall, open space, area or zone within a city, or other location. 
         [0035]    A user device  115  such as a laptop computer, PDA, Wi-Fi® phone, cellular phone, mobile handset, other portable device, or other computer based device is in data communication with an access point  113  via a communications link  119 . The access point generally provides access to a network (not shown). The access point uses an access code to permit the user device to access the network. 
         [0036]    Thus, for example, after the access point receives the access code from the user device, the access point thereafter allows the user device to access the network. In some embodiments the access point determines if the access code is proper, while in other embodiments another device, such as a device associated with the access point, may perform this function. In general, determining if an access code is proper may simply comprise determining if the access code is in a list of valid access codes, but more generally may include processing using the access code, for example, shared secret processing or other key related processing. 
         [0037]    As shown in  FIG. 1 , a cash register  111  is also in data communication with the access point via a communications link  117 . In most embodiments, the cash register provides the user device, or more often, a user associated with the user device, the access code, generally as a result of a commercial transaction for goods or services other than the service of access to the network. In some embodiments the cash register determines the access code for provision to the user. In many embodiments the access point, or some other device associated or communications with the access point, determines the access code and provides the access code to the cash register for provision to the user. 
         [0038]    Note the user device  115  in many embodiments does not actually have to be located within the physical confines of the venue, rather it may be in the vicinity of the venue or proximity of the venue. Similarly, the access point  113  may be located, in some embodiments, in the vicinity of the venue or proximity of the venue instead of physically within the bounds of the venue. 
         [0039]    As mentioned above, the access point  113  provides access to a network. For example, access to the network may be an entry point to a network where the user device  115  or the cash register  111  is able to send and receive data messages to and from another computer or device on the network. The user device  115  data couples, or connects, to the access point  113  for communication. For example, the user device  115  connects to the access point  113  for sending and receiving data messages to and from network components via the access point  113 . 
         [0040]    Examples of access points are the WCG200, WRT54G, and WAP546 by Linksys (www.linksys.com). In some embodiments, the access point has additional features. Firstly, the access point  113  may have the capability to determine access codes (ACs). In one embodiment, determining the AC comprises computing the AC. In an alternative embodiment, determining an AC comprises generating the AC. In another alternative embodiment, determining an AC involves a query to a RADIUS server or database. Secondly, the access point  113  in one embodiment contains a database used to store the access code, and possibly information associated with the access code, such as access allotment, or other information. 
         [0041]    The cash register  111  is used for commercial transactions. The cash register  111  may also be connected to the access point  113 . For example, the cash register  111  connects to the access point for sending and receiving data messages to and from network components via the access point  113 . In most embodiments the cash register is a business machine that usually has a money drawer, indicates the amount of each sale, records the amount of money received, prints a receipt for the transaction, has a processor and memory, and may contain I/O interfaces for connecting peripherals. The I/O interfaces may include VGA, USB, RS-232, RJ-45 for Ethernet, and RS-485, wireless interfaces such as IEEE 802.11, Bluetooth, or any other wireless based interface. Examples of the types of peripherals that might be connected to cash register  111  include but are not limited to credit card swipe, printer, video monitor, payment capture device, wireless interface, optical scanner, and credit card processing terminal. When a peripheral is connected with the cash register  111  then it is considered to be part of the cash register  111 . Examples of such cash registers include the IBM SurePOS 700 Series, the NCR RealPOS 80 Point-of-Service Workstation, or the Micros 3700. In other embodiments, the cash register  111  may be a stand alone credit card processing terminal. An example of a credit card processing terminal is the VX 570 offered by VeriFone. The VX 570 may include an Ethernet port for standard TCP/IP communications. 
         [0042]    The database may be used to store the AC and information associated with the AC such as an allotment, such as an allotment of time, data, or other quantity, associated with the AC. In one embodiment, the database may be integrated with the access point  113 . In this embodiment the access point  113  may communicate the AC to the cash register  111 . In an alternative embodiment, the database may be integrated with the cash register  111 . In this embodiment the cash register  111  simply provides the AC and additionally may communicate the AC to the access point  113  or other devices or computers on the network. In another alternative embodiment, the database is located external to both the access point  113  and external to the cash register  111 , a stand alone database. In this embodiment, the database may communicate the AC to the cash register  111  or other devices or computers on the network. In another embodiment the database may be located partially in the cash register  111  and partially in the access point  113 . In this embodiment the access point  113  or the cash register  111  may each communicate the AC or information about the AC to each other or other devices or computers on the network. In another embodiment, the cash register  111  may have a database integrated within it and a database external to the cash register may be available and have duplicate AC code information and duplicate information about the AC. In other embodiments, the database may be a RADIUS server located external to both the cash register  111  and access point  113 . In simplest form the AC is available to the cash register  111  and to the access point  113 , no database necessary. The database is not depicted in  FIG. 1 . The database may simply be flat files, may include relational tables such as those depicted in  FIGS. 13-15 , or may be data stored in registers. 
         [0043]    According to  FIG. 1  the cash register  111  connects to the access point  113  via communications link  117 . Data messages from or to the access point may travel on a wire or wirelessly. Communications link  117  in some embodiments is a wired communications link. In some embodiments, communications link  117  may be a standard wireless cellular phone connection as is known to those skilled in the art. In other embodiments, communications link  117  may be an EV-DO, GPRS or other data link across a cellular communications network. In another alternative embodiment, communications link  117  may be a standard Ethernet communications link. In each of the communication link  117  embodiments described herein there may include switches, routers and hubs, not shown in  FIG. 1 , between the cash register  111  and the access point  113 . Depending on the type of communications link  117  selected, the cash register  111  and access point  113  will have the necessary hardware and software to communicate across the selected type of communications link  117 . Communications link  117  may be a secure link. However, communications link  117  does not necessarily need to be designed to be secure. 
         [0044]    According to  FIG. 1  the access point  113  connects to the user device  115  via communications link  119 . Data messages from or to the access point may travel on a wire or wirelessly. In most embodiments, communications link  119  is a standard wired or wireless Ethernet communications link. In alternative embodiments, communications link  119  may be a standard wireless cellular phone connection as is known to those skilled in the art. In other embodiments, communications link  119  may be an EV-DO, GPRS or other data link across a cellular communications network. In another alternative embodiment, communications link  119  may be a standard Ethernet communications link. In each of the communication link  119  embodiments, described herein there may be switches, routers and hubs, not shown in  FIG. 1 , between the user device  115  and the access point  113 . Depending on the type of communications link  119  selected, the user device  115  and access point  113  will have the necessary hardware and software to communicate across the selected type of communications link  119 . Communications link  119  may be a secure link. However, communications link  119  does not necessarily need to be designed to be secure. 
         [0045]      FIG. 2  shows a flow chart of a process for providing an access code. The process may be performed, for example, by the system of  FIG. 1 . For example, the process elements in  FIG. 2  may be executed individually or in combination with either the user device  115 , the access point  113 , the cash register  111  or the database, not shown. The process receives a transaction amount for goods or services in block  213 . In most embodiments the transaction amount is for a commercial transaction. In one embodiment, the transaction amount for the goods or services comprises entering the transaction amount  213  in a cash register  111 , the cash register  111  receives the transaction amount. The process receives an access code in block  215 . In one embodiment, receiving an access code comprises the cash register  111  receiving the AC  215  from the access point  113 . In an alternative embodiment, the process receiving an access code in block  215  comprises the cash register  111  determining the AC without input from the access point  113 . In another alternative embodiment for block  215 , the access point  113  may receive the AC from the database. In another alternative embodiment for block  215 , the cash register  111  receives the AC  215  from its own memory. In another alternative embodiment for block  215 , the access point  113  may receive the AC from a RADIUS server. In an alternative embodiment, the cash register  111  may compute the AC without the need of input from the access point  113  or the database. In block  217  the process provides the access code to a consumer. In one embodiment, providing the access code to a consumer comprises a receipt printed out from the cash register  111  in order to provide the access code to the customer  217 . 
         [0046]    A commercial transaction comprises a transfer or provision of goods or services in exchange for a payment. The delivery of the goods or services does not necessarily occur when the payment occurs. The delivery of the goods or services independent of the payment may be considered a commercial transaction. The payment whether a good or service is then received is also considered a commercial transaction. In one embodiment a commercial transaction may be a purchase of coffee at a retail establishment. In this example, the payment of money is tendered for a good or service at the time the good is delivered. Other examples of this type of commercial transaction may be the purchase of a car, books, groceries, alcohol, movie ticket, soda from a vending machine, admission to a theme park. In another embodiment a commercial transaction may be a customer purchasing a subscription. In this example, a commercial transaction occurs when the customer purchases the subscription initially as well as each time the subscription is fulfilled. An example of this type of commercial transaction is cable television. Each month the cable customer enters into a commercial transaction by paying for cable service. Additionally, a commercial transaction occurs each time the customer turns on the cable television and watches a program because the cable television company is delivering on the subscription. Similarly, a wireless phone subscriber enters a commercial transaction each month by paying his monthly bill. Additionally, each time the wireless phone subscriber uses the wireless phone a commercial transaction occurs. Another type of commercial transaction may be when payment is not tendered in money but rather in something else that has value such as frequent flyer miles, gift certificates, credits or other value that is non-monetary. For example, a customer of an airline may make payment for network access using an allotment of frequent flyer miles as payment. 
         [0047]      FIG. 3  shows a flow chart of a process for providing an access code in conjunction with use of a database. The process may be performed, for example, by a system such as  FIG. 1  interacting with a database. For example, the process elements in  FIG. 3  can be executed individually or in combination either at the user device  115 , the access point  113 , the cash register  111  or the database, not shown. The process receives a transaction amount for goods or services in block  313 . In one embodiment, a commercial transaction takes place as described above and the transaction amount for the goods or services is entered in block  313  in a cash register  111 . The process determines access allotment in block  315 . In one embodiment, the cash register  111  determines the access allotment  315 . In one embodiment, determining the access allotment comprises querying a database. In an alternative embodiment, determining the access allotment comprises performing a computation based on the transaction amount of goods or services. In an alternative embodiment, the cash register  111  determines the access allotment from its own memory. 
         [0048]    The process in block  317  receives the access code. In one embodiment, the cash register  111  receives the access code  317  from the access point  113 . In an alternative embodiment, the cash register  111  determines the AC without input from the access point  113 . In another alternative embodiment, the access point  113  receives the AC from the database. In another alternative embodiment, the access point receives the AC from the RADIUS server. In another alternative embodiment for block  317 , the cash register  111  receives the AC  317  from its own memory. In an alternative embodiment, the cash register  111  computes the AC without the need of input from the access point  113  or the database. In this case, process may skip block  317 . In block  319  the process records the access allotment with the access code. In one embodiment, the cash register  111  records in the database the access allotment with the access code  319 . 
         [0049]      FIG. 4  shows a flow chart of a process for how the system in  FIG. 1  grants access to a network. Typically a user of a user device  115  is in the vicinity or proximity of a venue containing the elements in  FIG. 1  after entering into a commercial transaction for goods or services with the venue owner/operator. In block  413  the process receives an access code. In one embodiment, the process receives an access code  413  comprises the user entering the access code  413  issued to him by some of the methods described in  FIGS. 2 and 3 . In block  415  the process verifies that an allotment exists. In one embodiment, the access point  113  checks to verify that an allotment exists under the AC  415 . In one embodiment, verifying that an allotment exists comprises validating the access code, for example, determining if the access code comprises a valid access code or key. In another embodiment, verifying that an allotment exists comprises validating the access code and checking the remaining allotment. In an alternative embodiment, verifying that an allotment exists comprises validating the access code, checking the remaining allotment and verifying that the window has not expired. In some embodiments, in order to perform  415  the access point  113  may communicate with the cash register  111 , the database or both. In block  417  the process provides access to the network. In one embodiment, the access point  113  provides access to the network  417 . In the event that the allotment fails to exist under the users AC then the process does not allow access to the network. In one embodiment, the process not allowing access comprises the access point  113  not allowing access to the network. 
         [0050]    The system shown in  FIG. 1  depicts the elements for a single venue configuration. It is also contemplated in the instant invention that multiple related venues may be configured. For example the system of  FIG. 1  may be connected to another system similar to  FIG. 1  via the Internet to the access points. In such a multiple venue configuration, a commercial transaction that occurs at one venue may allow for the granting of network access at another related venue. For example, a customer may perform a commercial transaction at a coffee shop chain. The customer may instead of sitting down at the coffee shop, where the commercial transaction took place, drive to another coffee shop in the same chain and sit down there and gain access to the network. 
         [0051]    The process elements in  FIG. 5  can be executed individually or in combination either at the user device  115 , the access point  113 , the cash register  111  or the database, not shown. The process receives a transaction amount for goods or services in block  513 . The process in block  515  obtains an access code. In block  517  the process determines access allotment. The process in block  519  provides an access code to a consumer. In block  521  the process receives an access code. In block  523  the process verifies the access code. If the access code is valid, then the process in block  525  provides access. Otherwise, if the access code is invalid, then access is not provided and the process proceeds to block  527 . 
         [0052]      FIG. 6  shows a system configured for a single venue. The system contains an access point  619 , an cash register  623 , a database  617 , a proxy server  625 , and a plurality of user devices  611 ,  613 ,  615 . The access point  619 , database  617 , and proxy server  625  can each individually be located at the venue or at a location apart from the venue. In some embodiments, the access point  619  connects to the Internet with out the use of the proxy server  625 . In otherwords, the proxy server  625  is optional. Although the database  617  is shown to be separate from the access point  619 , it is important to realize that the database can be located inside the cash register  623 , or inside the access point  619  or be partially inside the access point  619  and the cash register  623 . Although  FIG. 6  shows a single cash register  623 , in alternative embodiments there are a plurality of cash registers similar to cash register  623 . 
         [0053]    The plurality of user devices  611 ,  613 ,  615  may connect to the access point  619  via communications link  629 . As discussed previously the user devices  611 ,  613 ,  615  can be laptop computers, PDAs, Wi-Fi® phones, cellular phones, mobile handsets, other portable devices, or other computer based devices. Although  FIG. 6  shows a plurality of user devices  611 ,  613 ,  615 , it is not required that all of the user devices communicate with the access point  619  at the same time. In one embodiment, one user device may be in the vicinity or proximity of the venue communicating via communications link  629 . Alternatively, it is also an embodiment, that a plurality of user devices may communicate across communications link  629  simultaneously. Note the user devices  611 ,  613 ,  615  do not actually have to be located at the venue rather they may be in the vicinity of the venue or proximity of the venue. 
         [0054]    The access point  619 , similar to the access point  113  in  FIG. 1 , can be a device that provides access to a network. Examples of access points are the WCG200, WRT54G, and WAP546 by Linksys (www.linksys.com). In some embodiments, the access point may have several additional features. Firstly, the access point  113  may have the capability to determine the ACs. In one embodiment, determining the AC comprises computing the AC. In an alternative embodiment, determining the AC comprises generating the AC. In another alternative embodiment, determining the AC involves a query to a RADIUS server or database. Secondly, the access point  619  in one embodiment contains a database. 
         [0055]    The proxy server  625  is a computer. The proxy server executes software that allows it to control access to the communications link  633 . In most embodiments, the proxy server  625  manages all Internet related communications by monitoring Internet Protocol (“IP”) source and destination addresses, port numbers, and various other information inside standard Ethernet packets. The proxy server  625  uses rules to determine which Ethernet packets are allowed entrance or exit to and from the proxy server  625 . Generally, the rules are programmed into software that executes on the proxy server  625  computer. The functions of the proxy server  625  and its make up are generally known to those skilled in the art. In some embodiments the proxy server  625  delivers cached web pages. In alternative embodiments, the proxy server  625  forces a user device to browse a web page so the user may authenticate himself before freely surfing the Internet. The proxy server  625  is optional and in many embodiments is not part of the design. In alternative embodiments, the access point  619  may partially perform proxy server functions. In another alternative embodiment, the access point  619  performs all of the proxy server functions. 
         [0056]    The database may be used to store the AC and information about the AC such as the allotment of time associated with the AC. In one embodiment, the database may be integrated with the access point  619 . In this embodiment the access point  619  may communicate the AC to the cash register  623 . In an alternative embodiment, the database may be integrated with the cash register  623 . In this embodiment the cash register  623  simply provides the AC and additionally may communicate the AC to the access point  619  or other devices or computers on the network. In another alternative embodiment, the database is located external to both the access point  619  and external to the cash register  623 , a stand alone database. In this embodiment, the database may communicate the AC to the cash register  623  or other devices or computers on the network. In another embodiment the database may be located partially in the cash register  623  and partially in the access point  619 . In this embodiment the access point  619  or the cash register  623  may each communicate the AC or information about the AC to each other or other devices or computers on the network. In another embodiment, the cash register  623  may have a database integrated within it and a database external to the cash register may be available and have duplicate AC code information and duplicate information about the AC. In other embodiments, the database may be a RADIUS server located external to both the cash register  623  and access point  619 . In other alternative embodiments, the database  617  may be a part of the proxy server  625 . In simplest form the AC is available to the cash register  623  and to the access point  619 , no database necessary. The database may simply be flat files, may include relational tables such as those depicted in  FIGS. 13-15 , or may be data stored in registers. 
         [0057]    The cash register  623  is similar to the cash register  111 . In some embodiments the cash register  623  may print out a receipt with an AC. An example of such a receipt may be seen in  FIG. 9 . 
         [0058]    In most embodiments, communications links  629 ,  635 ,  621 , and  631  are standard wired or wireless Ethernet communications link. In alternative embodiments, these communications link may be a standard wireless cellular phone connection as is known to those skilled in the art. In other embodiments, these communications links may be an EV-DO, GPRS or other data link across a cellular communications network. Depending on the type of communications links selected, the user devices  611 ,  613 ,  615 , database  617 , access point  619 , cash register  623 , and proxy server  625  will all have the necessary hardware and software to communicate across the selected type of communications links. In each of the communication link embodiments, described herein there may be switches, routers and hubs, not shown in  FIG. 6 . These communications links may be secure links. However, these communication links do not necessarily need to be designed to be secure. Communications links  629 ,  635 ,  621  and  631  do not all have to be the same type of communications links. 
         [0059]    In most embodiments, communications link  633  is a standard DSL, Wireless Cable, Cable modem, Optical or T 1  link that is capable of transporting standard Ethernet based communications. In alternative embodiments, communications link  633  may be a standard wireless cellular phone connection as is known to those skilled in the art. In other embodiments, communications link  633  may be an EV-DO, GPRS or other data link across a cellular communications network. In each of the communication link embodiments, described herein there may be switches, routers and hubs, not shown in  FIG. 6 . Depending on the type of communications link  633  selected, access point  619 , or optionally proxy server  625  will have the necessary hardware and software to communicate across the selected type of communications link  633 . Communications link  633  may be a secure link. However, communications link  633  does not necessarily need to be designed to be secure. 
         [0060]      FIG. 7  shows a flow chart of a process for how the system in  FIG. 6  handles a commercial transaction. The process in  713  receives the goods or services transaction amount. In one embodiment, the goods or services transaction amount is entered in the cash register  623 . In block  715  the process may receive a promotional code. If no promotional code is available then the promotional code is default such as 1,  719 . Otherwise, a promotional code is received by the process at  717 . Next in block  721  of the process the access allotment is determined. In some embodiments, this determination may be a query to a database table such as the table depicted in  FIG. 14 . For example row  1413  shows that if the promotional code is 1 (default) and the transaction amount is less than $5.99 then an allotment of 15 minutes is allocated. In other embodiments, this determination may be a computation that executes inside the cash register  623  for computing the access allotment. In block  723  of the process a record is created, recording the access code along with other transactional information. 
         [0061]    In most embodiments, the AC may be an alpha-numeric number. This number may simply increment each time an access code is assigned to a transaction. In other embodiments the access code may be a number. This number may simply increment each time an access code is assigned to a transaction. Alternatively, the AC may be a random number or a random alpha-numeric number. The number or alpha-numeric may be generated randomly from a random number generator. In most embodiments the access code is unique to the system that it is being implemented in. Once an AC is recorded in a record such as the record in row  1313 , then the AC has been assigned and should not be assigned again at least until the window expires. In an alternative embodiment, the AC can be the transaction ID. In other embodiments, the AC can be an airline record locator number or a frequent flyer number. In other embodiments the AC may be a user name and password. 
         [0062]      FIG. 13  shows an database table with the AC as the primary key. Row  1313  depicts a sample record. The elements included in the record,  FIG. 13 , row  1313  are the access code, venue ID, promotional code, transaction amount, transaction date, transaction time, allotment allocated and allotment remaining. In alternative embodiments, the record is not limited to these elements and may include other elements and possibly less elements in the record. For example, the column allotment allocated  1329  may be optional since it is the same as column  1435  in the database table in  FIG. 14 . A record as stated above is a row in  FIG. 13 , such as row  1313  or row  1315 . A Column in  FIG. 13  depicts a single element for the records in the table. For example, column  1325  shows the transaction date elements for each of the records in rows  1313  and  1315 . 
         [0063]    Column  1317  shows all of the ACs for each of the records in the table. An AC has been described previously. Column  1319  shows all of the Venue IDs for each of the records in the table. A venue ID may be comprised of a number, alpha-numeric number, letter, word, or symbol that uniquely identifies each venue or location. For example, if a coffee shop chain has  10  different locations then each of the  10  different location will be assigned a unique venue ID. Alternatively, a single venue ID may be assigned to each of the different locations. Column  1321  shows all of the promotional codes used in each of the records in the table. A promotional code may be comprised of a number, alpha-numeric number, letter, word, or symbol that helps identify the type of transaction. For example, a promotional code of  1  defines a transaction where the allotment is determined by the transaction amount. For example, if the promotional code is 1 and the transaction amount is less than $5.99 (the transaction threshold) then the allotment remaining will be set to 15 minutes giving the user of a particular AC 15 minutes of access. If the transaction amount had been greater than $5.99 but less than $9.99 then the allotment remaining will be set to 30 minutes giving the user of a particular AC 30 minutes of access. Column  1323  shows all of the transaction amounts used in each of the records in the table. The transaction amount may be comprised as the actual dollar amount spent in a commercial transaction, a number or alpha-numeric number related to the amount spent in a commercial transaction, or a letter, word, or symbol related to the amount spent in a commercial transaction, frequent flyer miles, number of watts used in a power grid, minutes in a wireless cellular network or any number, alpha-numeric number, letter, word, or symbol that relates to something of value. The tax in a commercial transaction may or may not be included in the transaction amount. For example if a customer at a coffee shop purchases a cup of coffee for $4.99 then the transaction amount will be stored in the database table as $4.99 in column  1323 . Column  1325  shows all of the transaction dates in each of the records in the table. The transaction date may be comprised as the actual date the commercial transaction occurred, a number related to the actual commercial transaction date such as the julian date, or may be an alpha-numeric number, letter, word, or symbol related to the actual commercial transaction date. Column  1327  shows all of the transaction times in each of the records in the table. The transaction time may be comprised as the actual time the commercial transaction occurred. The transaction time may be expressed with a 12 hour clock, a 24 hour clock, or a number related to the actual time the commercial transaction occurred. Column  1329  shows all of the allotments allocated in each of the records in the table. The allotment allocated may be comprised as a number, alpha-numeric number, letter, word or symbol that describes an amount of access allocated to an AC. For example, an allotment allocated may be the number of minutes of access time. Or, an allotment allocated may be the number of mega bytes allowed to download or upload or both to a network. Column  1331  shows all of the allotments remaining in each of the records in the table. The allotment remaining may be comprised as a number, alpha-numeric number, letter, word or symbol that describes an amount of access remaining to an AC. For example, an allotment remaining may be the number of minutes of access time left in a users session. Or, an allotment remaining may be the number of mega bytes remaining to download or upload or both to a network. It should be noticed to those skilled in the art that  FIGS. 13 and 14  represent tables in a relational database. Thus in order to get all of the information required, queries to both tables may be necessary depending on which information is in each of the tables.  FIGS. 13 and 14  show data in the table with its units. For example in, row  1313  column  1331 , the table contains the element  1  MIN. The units displayed in  FIGS. 13 and 14  are for illustrative purposes only. Those skilled in the art will understand that the units may not necessarily be included in the database tables.  FIG. 14  shows an database table. This database table determines the allotments granted and window periods assigned given the transaction amounts, promotional code, and venue ID. In most embodiments, the table in  FIG. 14  is determined in advance prior to any commercial transactions. Row  1413  depicts a sample record. The elements included in the record,  FIG. 14 , row  1413  are the venue ID, promotional code, transaction threshold, allotment, and window. In alternative embodiments, the record is not limited to these elements and may include other elements and possibly less elements in the record. A Column in  FIG. 14  depicts a single element for the records in the table. For example, column  1433  shows the transaction threshold elements for each of the records in rows  1413 - 1427 . 
         [0064]    Column  1429  shows all of the venue IDs for each of the records in the table in  FIG. 14 . The venue ID was discussed previously and is the same as the venue ID in  FIG. 13 . Column  1431  shows all of the promotional codes used in each of the records in the table in  FIG. 14 . The promotional code was discussed previously and is the same as the promotional code in  FIG. 13 . Column  1433  shows all of the transaction thresholds for each of the records in the table in  FIG. 14 . The transaction threshold may be comprised as an actual dollar amount spent in a commercial transaction, a number or alpha-numeric number related to the amount spent in a commercial transaction, or a letter, word, or symbol related to the amount spent in a commercial transaction, frequent flyer miles, number of watts used in a power grid, minutes in a wireless cellular network or any number, alpha-numeric number, letter, word, or symbol that relates to something of value. The transaction thresholds are used to group various transaction amounts and assign particular allotments and windows. For example, if a customer enters into a transaction at venue ID=SB001 and the promotional code=1 and the transaction amount is greater than $5.99 but less than $9.99 (transaction threshold) then the allotment will be assigned 30 minutes with a window of 60 minutes. The transaction thresholds in this example are used to assign the correct allotment and window. In row  1425  and  1427  the transaction thresholds are valid only when the transaction amount is equal to the transaction threshold. This type of transaction threshold, in some embodiments represent situations when a customer wants to purchase straight access time allotment. For example, in row  1425 , if a clerk enters an amount of $100.00 and a promotional code of 2 then the access code will be assigned an allotment of 200 minutes with no expiration window. In row  1427 , if a clerk enters an amount of $50.00 and a promotional code of 3 then the access code will be assigned an allotment of 120 minutes but with an expiration window of one year from the commercial transaction date. Column  1435  shows all of the allotments used in each of the records in the table in  FIG. 14 . The allotments in column  1435  is the same as the allotments allocated in column  1329  in  FIG. 13  and was discussed previously. Column  1437  shows all of the windows for each of the records in the table in  FIG. 14 . The window may be comprised as the amount of time that the AC is valid following the date and time of the commercial transaction. The window may be expressed with a 12 hour clock, a 24 hour clock, minutes, seconds, or a number related to time such as the julian date. For example in row  1423 , the window is for a period of time that begins on the date and time that the commercial transaction occurred and ends on a specific date Feb. 22, 2007. This means that the access code will expire or be invalid on the date Feb. 22, 2007. Whereas, in row  1413  the window is 30 minutes. This means that the window is for a period of time that begins on the date and time that the commercial transaction occurred and ends 30 minutes later. Row  1425  shows that there is no window. Thus, this type of transaction will have an AC that will be good until all of the access time is used up. 
         [0065]    As can be seen by those of skill in the art the tables in  FIGS. 13 and 14  can be configured to handle any sales, marketing or promotion of access one can think of.  FIG. 14  shows data in the table with its units. For example in, row  1413  column  1437 , the table contains the element 30 MIN. The units displayed in  FIG. 14  are for illustrative purposes only. Those skilled in the art will understand that the units may not necessarily be included in the database table. Additionally, the format of the elements are for illustrative purposes only. For example, the element in row  1413 , column  1433  is &lt;$5.99. The less than symbol may not actually be included in the table. Rather the function less than (&lt;) may be implemented in software code. 
         [0066]      FIG. 15  shows an database table. This database table determines which venues have access to the network. In some embodiments, the table in  FIG. 15  is determined in advance prior to any commercial transactions. Row  1511  depicts a sample record. The elements included in the record,  FIG. 15 , row  1511  are MAC address and the venue ID. In alternative embodiments, the record is not limited to these elements and may include other elements and possibly less elements in the record. 
         [0067]    The MAC address comprises the identification of the Network Interface Card (“NIC”) of the either the access point  1119  or the optional proxy server  1123 . In a multiple venue embodiment, such as that in  FIG. 10 , the table in  FIG. 15  will be queried to ensure that the access point or proxy server is identified. If the MAC address is matched up against a venue then access may be granted. However, if the MAC address is not matched up to a venue then access will be denied. 
         [0068]      FIG. 8  shows a flow chart of a process for how the system in  FIG. 6  grants access to a network. In block  813  of the process the AC is received. In one embodiment, the AC may be entered into the cash register  623 . In block  815  of the process the venue ID is checked. In some embodiments, process block  815  is optional in a single venue configuration as in  FIG. 6 . In a single venue configuration process  815  may be used to prevent intruders from unauthorized locations from gaining access to the network. In a multiple venue configuration process  815  is important because only authorized venues are allowed to access the network. In one embodiment, the venue ID may be checked by examining the MAC address in the Ethernet type communications. Once the MAC address is determined, a queries to other tables such as the table in  FIG. 14  may be performed. If the MAC address is associated with a venue ID then the check is complete. In another embodiment, the venue may be validated by simply presenting the user with an opportunity to enter the venue ID. The venue ID in this embodiment may be printed on a receipt such as the receipt in  FIG. 9 . If the venue ID is valid the process continues to block  817  otherwise, the process returns to block  823 . In block  817  the process verifies that an allotment exists. In one embodiment, the access point  619 , cash register  623 , database  617 , or proxy server  625  checks to verify that an allotment exists under the AC  817 . In another embodiment, verifying that an allotment exists comprises validating the access code. In another embodiment, verifying that an allotment exists comprises validating the access code and checking the remaining allotment. In some embodiments, the access point  619 , cash register  623 , database  617 , or proxy server  625  may communicate with each other individually or in plurality. In block  819  the allotment expiration is checked  819 . In some embodiments, if the allotment exits then the window is checked against the current date and time. If the window has expired, then access is denied. Finally, if the window has not expired access is allowed  821 . According to the process loop between  821  and  817  the allotment and allotment expiration are repeatedly checked at any interval chosen by the venue operator. While providing access in  821  the allotment remaining may be updated in the database every so often in order to keep the data accurate. 
         [0069]      FIG. 9  shows a sample printed receipt  911 . At the top of the receipt is the name, address, and telephone number of the venue  913 . At  915  is a transaction ID. The transaction ID is used to track each transaction the venue operator creates. At  917  is the time and date stamp of the actual transaction.  919  describes the goods or services sold in the transaction.  921  indicates the tax added on to the transaction.  923  shows the total amount of the transaction including tax.  925  shows the venue ID for where network access may be granted. If access may be granted at more than one venue then multiple venue IDs may be displayed. Venue IDs may be coded in such a way that a single venue ID may provide access at multiple different venues.  927  shows the access code.  929  shows the amount of access granted. In this example  15  minutes was granted.  931  shows the date and time that the access will expire. While the transaction ID  915  is indicated on receipt  911  it is in most embodiments a unique number. The transaction ID  915  in an alternative embodiment may be used as the access code  927 . In an alternative embodiment, the venue ID may not be shown at all. 
         [0070]      FIG. 10  shows a multiple venue configuration where venue # 1  through venue #J (J is an integer) are related. The first venue in  FIG. 10  is the venue depicted in  1011 . The last venue related to venue  1011  is venue #J  1027 . In this particular multiple venue embodiment venue  1011  contains user devices  1013 ,  1015 ,  1017 , an access point  1021 , a cash register  1023  and communications links  1019  and  1025 . Venue  1011  can communicate via its access point  1021  to the central database  1045  across communications links  1043  and  1051  and the Internet. In an alternative embodiment, the venue may be comprised of an optional proxy server similar to proxy server  1025  located at the venue. The proxy server may buffer communications between the access point  1021  and the Internet along communications link  1043 . In another alternative embodiment, the venue may be comprised of a database similar to database  617 . The remaining venues in this embodiment are similar and will not be repeated. 
         [0071]    The plurality of user devices  1013 ,  1015 ,  1017  may connect to the access point  1021  via communications link  1019 . As discussed previously the user devices  1013 ,  1015 ,  1017  can be laptop computers, PDAs, Wi-Fi® phones, cellular phones, mobile handsets, other portable devices, or other computer based devices. Although  FIG. 10  shows a plurality of user devices  1013 ,  1015 ,  1017 , it is not required that all of the user devices communicate with the access point  1021  at the same time. In one embodiment, one user device may be at the venue communicating via communications link  1019 . Alternatively, it is also an embodiment, that a plurality of user devices may communicate across communications link  1019 . 
         [0072]    The database  1045  is similar to database  617 . 
         [0073]    The communication links  1019  and  1035  are similar to communication links  629  and  119  will not be discussed again. Communication links  1043 ,  1047 , and  1051  are similar to communication link  633  and will not be discussed again. Communication links  1025  and  1041  are similar to communication links  621 , and  117  and will not be discussed again. 
         [0074]    The methods for controlling network access in a multiple venue configuration as in  FIG. 10  have been discussed previously and can be seen in  FIGS. 2 ,  3 ,  4 ,  7 , and  8 . 
         [0075]    According to  FIG. 6  a cash register  623  is utilized for a commercial transaction. In an alternative embodiment the cash register  623  may be optionally replaced with a general computer. In either case both the cash register  623  and optionally the general computer may be capable of printing a receipt as shown in  FIG. 9 . In an alternative embodiment both the cash register  623  or optionally the general computer may also encode a magnetic strip on the back of a gift card with the access code information. Alternatively, the cash register  623  or optionally the general computer may also be capable of putting the access code information on a memory device such as a USB memory key, or any other non-volatile memory. The cash register  623  or optionally the general computer may also able to issue a prepaid access code card. A prepaid access code card, in an alternative embodiment, may have the AC written on the surface of the card but covered by a substance such that when scratched off the AC becomes visible. Examples of hiding information on a card can be seen in lottery tickets where the numbers can be found by scratching off a substance with a finger nail or coin. 
         [0076]    The cash register  623  in  FIG. 6  may be optionally replaced by an airline ticketing computer. An airline ticketing computer is a typical computer that issues airline tickets, boarding passes, and offers airline information. These computers typically reside in airports, kiosks, travel agencies and/or are accessed via the Internet. The software typically running on an airline ticketing computer is made by Sabre. According to the instant invention, an airline ticketing computer has the ability to issue airline tickets, boarding passes, or paper with ACs indicated on it. The algorithms for issuing ACs in this embodiment and granting access are the same as the algorithms discussed above and depicted in  FIGS. 2 ,  3 ,  4 ,  7  and  8 . 
         [0077]    The database tables for the airline ticketing embodiment are similar to the tables depicted in  FIGS. 12 ,  13 , and  14  with the following changes. In  FIG. 12  column  1217  may be changed to frequent flyer # instead of AC. And column  1223  may be changed to frequent flyer miles. In  FIG. 13  column  1333  may be changed to frequent flyer mile thresholds. No changes are required in  FIG. 14 . The commercial transactions that take place in this embodiment will utilize the number of frequent flyer miles as payment. And the frequent flyer # or record locator number as the access code. 
         [0078]      FIG. 11  shows a system configured for a single venue. The system contains an access point  1119 , an cash register  1121 , a database  1117 , a proxy server  1123 , an interactive voice response unit (“IVR”), and a plurality of user devices  1111 ,  1113 ,  1115 . The access point  1119 , database  1117 , and proxy server  1123  can each individually be located at the venue or at a location apart from the venue. In some embodiments, the access point  1119  connects to the Internet with out the use of the proxy server  1123 . In otherwords, the proxy server  1123  is optional. Although the database  1117  is shown to be separate from the access point  1119 , it is important to realize that the database can be located inside the cash register  1121 , or inside the access point  1119  or be partially inside the access point  1119  and the cash register  1121 . Although  FIG. 11  shows a single cash register  1121 , in alternative embodiments there are a plurality of cash registers similar to cash register  1121 . 
         [0079]    The plurality of user devices  1111 ,  1113 ,  1115  are similar to the user devices  611 ,  613 ,  615 . A discussion of user devices  1111 ,  1113 ,  1115  will not be repeated here. The optional proxy server  1123  is similar to proxy server  625  and a discussion will not be repeated. The database  1117  is similar to database  617  and a discussion will not be repeated. The cash register  1121  is similar to the cash register  623  and a discussion will not be repeated. 
         [0080]    The IVR  1125  is a computer system that delivers pre-programmed audio messages from an audio response unit (“ARU”) either built into the IVR or separate. The IVR  1125  is also capable of receiving DTMF tones or data from user devices. Examples of IVR units include IVR products from BCE Elix, Cisco IP IVR, Apex, and Aspect. The IVR unit in the instant invention is used to deliver an audio message asking a user to enter an access code. The IVR will receive the access code and either process it according to the algorithms discussed previously or send the AC to the access point  1119  or optionally to the proxy server  1123  where the access point  1119  or optionally the proxy server  1123  will process according to the algorithms discussed previously. Additionally, the IVR  1125  may also inform the user how many minutes are left until the expiration of the AC. 
         [0081]    The communication link  1129  is similar to communication links  119 ,  629 ,  1019  and  1035  and will not be discussed again. Communication links  1137  is similar to communication links  621 ,  1025 , and  1041  and will not be discussed again. Communication link  1135  is similar to communication links  633 ,  1043 ,  1047 , and  1051  and will not be discussed again. 
         [0082]    Although  FIG. 11  depicts a single venue configuration. In an alternative embodiment  FIG. 11  can be adapted to be configured for a multiple venue configuration as in  FIG. 10 . 
         [0083]      FIG. 12  shows a process for granting access to a network. The process of  FIG. 12  is performed, for example, by the system of  FIG. 11 . A user device is connected to the network  1213 . An IVR audio message is delivered to the connected user device  1215 . AC is entered from user device  1217 . Next, the venue ID is checked  1219 . Process  1219  is optional in a single venue configuration as in  FIG. 11 . In a single venue configuration process  1219  is used to prevent intruders from unauthorized locations from gaining access to the network. In a multiple venue configuration this is important because only authorized venues are allowed to access the network. Next the access point  1119  checks to verify that an allotment exists under the AC  1221 . In one embodiment, verifying that an allotment exists comprises validating the access code. In another embodiment verifying that an allotment exists comprises validating the access code and checking the remaining allotment. In order to perform  1221  the access point  1119  may communicate with the cash register  1121 , the database  1117 , the IVR  1125  or all. Next the allotment expiration is checked  1223 . If the allotment exits then the window is checked against the current date and time, in most embodiments. If the window has expired, then access is denied. Finally, if the window has not expired access is allowed  1225 . Next according to the loop between  1225  and  1221  the allotment and allotment expiration are repeatedly checked at any interval chosen by the venue operator. While providing access in  1225  the allotment remaining may be updated in the database every so often in order to keep the data accurate. 
         [0084]    It should be noted that the words used in this specification to describe the instant embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use must be understood as being generic to all possible meanings supported by the specification and by the word or words describing the element. 
         [0085]    In addition, the definitions of the words or drawing elements described herein are meant to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements described and its various embodiments or that a single element may be substituted for two or more elements in a claim. 
         [0086]    Changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalents within the scope intended and its various embodiments. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. This disclosure is thus meant to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted, and also what incorporates the ideas herein.
