         TECHNICAL FIELD OF THE INVENTION  
         [0010]    The present invention is directed to electronic ticket control systems and, more specifically, to a system and method for selling and controlling admission to a large public  
         BACKGROUND OF THE INVENTION  
         [0011]    Large public entertainment facilities, such as convention centers, concert halls, stadiums, sports arenas, and the like, are the civic centers of many communities and are important sources of revenue and employment. Quite often, public facilities are funded by taxpayers in order to attract or at least retain sports franchises, and to attract tourists and conventions. The large sums invested in public entertainment facilities make it essential to maximize the revenue derived from such facilities and to minimize their operating costs.  
           [0012]    However, large public facilities tend to be labor intensive operations. A typical sports facility requires a large number of gate attendants, ticket agents, ushers, concession stand operators, shop vendors, and security officers, and the like. Many new sports facilities also employ waiters and waitresses who take orders from, and serve food and drink to, customers at their seats. Facility operators use labor-saving technology wherever possible in order to offset the high labor costs associated with large public facilities.  
           [0013]    There is therefore a need in the art for technical improvements that reduce the costs of operating large public entertainment facilities. In particular, there is a need for new technologies that help to reduce labor costs associated with a operating large public facilities. Additionally, there is a need for technical improvements that enhance the revenues of large public facilities. More particularly, there is a need for new technologies that provide useful and enjoyable services to the patrons of large public facilities.  
         SUMMARY OF THE INVENTION  
         [0014]    To address the above-discussed deficiencies of the prior art, it is a primary object of the present invention to provide a method and system which allows a facility operator to increase revenue by selling customers optional guaranteed advance admission to the best seat in the facility which remains available at the time of a future event. The method and system make advantageous use of a virtual ticket device.  
           [0015]    In its simplest form, the virtual ticket device is an existing smart telephone or cellular communication-enabled personal digital assistant (PDA), such as a PALM PILOT™ or a VISOR™ electronic organizer, a portable video game controller or a portable personal computer. A dedicated virtual ticket device could also be used. A customer who wishes to attend an event purchases admission in any conventional manner (e.g., by telephone from a ticket service, in person at a box office, via the Internet). The ticket vendor sends an encrypted admission authorization record over a wireless channel or a wireline channel to the virtual ticket device, where it is stored as a virtual electronic ticket.  
           [0016]    The encrypted admission authorization record may include, for example, information which identifies the date and location of the event, the seat number, price paid, and the like. The encrypted admission authorization record also may include uniquely encrypted information which may be used in a conventional manner to authenticate that the record is genuine. The same information is preferably stored in a central database which is accessible by the event operator and/or his service provider. The record in the database should preferably also include the telephone number or wireless address of the virtual ticket device so that contact with the virtual ticket device may be established at a later time.  
           [0017]    Entry point terminals are provided at the entrances of the public entertainment facility which read at least the encrypted authentication information from the virtual ticket device and authorize the customer to enter the event. The entry point terminals read the authentication information over a very short range wireless (RF) channel or infrared (IR) channel, or via a dedicated interface slot coupled to a wireline channel to prevent eavesdropping and spoofing of the process. For example, the virtual ticket device may be programmed to display the data either as a string of characters (e.g., serial number) or a bar code on its LCD display and the displayed information can be optically scanned in a chamber of the entry point terminal.  
           [0018]    Preferably both the virtual ticket device and the arena or theater is also equipped with hardware and software which can track the location of the virtual ticket device in and around the entertainment facility with a precision of perhaps a few meters. Once the customer has purchased a virtual ticket, the virtual ticket device can be used, in conjunction with information stored in the database to provide a number of distinct information and marketing services to the customer.  
           [0019]    A virtual ticket control system interoperates with the above-described virtual ticket devices. The virtual ticket control system controls admission of customers to a public facility. According to an advantageous embodiment of the present invention, the virtual ticket control system comprises: 1) a plurality of terminal devices capable of being disposed at entry points to the public facility, a first one of the terminal devices capable of establishing a communication link to a virtual ticket device used by a customer and receiving a virtual ticket transmitted by the virtual ticket device; and 2) a virtual ticket authentication controller capable of receiving the received virtual ticket from the first terminal device and determining if a unique identifier associated with the received virtual ticket matches one of a plurality of stored unique identifiers associated with a plurality of authorized virtual ticket records stored in a memory associated with the virtual ticket authentication controller. In response to a determination that the unique identifier associated with the received virtual ticket matches one of the plurality of stored unique identifiers, the virtual ticket authentication controller transmits to the first terminal device an authorization message indicating that the received virtual ticket is valid.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0025]    [0025]FIGS. 1 through 5, discussed below, and the various embodiments used to describe the principles of the present invention in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the invention. Those skilled in the art will understand that the principles of the present invention may be implemented in any suitably arranged communications network capable of communicating with virtual ticket devices.  
         [0026]    [0026]FIG. 1 is a plan view of public facility  100  in which an electronic ticket control system according to the principles of the present invention may be deployed. Public facility  100  is representative of any public venue that is capable of holding a large audience. Thus, public facility  100  may include a football or baseball stadium, a basketball or hockey arena, a large concert hall, a convention center, and the like. As used herein and for the purpose of determining the scope of the claims of the present invention, the term “public facility” may include any controlled-access location to which people may be admitted by means of an electronic ticket control system and should not be construed to exclude facilities that are privately owned or that are open only to selected portions of the general public. In fact, public facility  100  may include controlled-access private clubs and private buildings, and even controlled-access forms of transportation, such as trains, planes, cruise ships, and the like. However, for the purpose of simplicity in explaining the principles of the present invention, it shall be assumed that public facility  100  is a sports facility.  
         [0027]    Public facility  100  comprises a plurality of seating areas, including exemplary seat sections  101 - 110 , that surround a playing area (e.g, hockey rink, basketball court, indoor track, or the like). Suspended over the playing area is multi-sided display (MSD)  120 , which has large display screens on four sides. The seating areas are surrounded by an exterior promenade area that contains a plurality of concession stands (CS), including four exemplary concession stands labeled CS1, CS2, CS3 and CS4. The promenade area also includes a number of rest rooms (RR), including exemplary rest rooms labeled RR1, RR2, RR3 and RR4, and numerous vendor shops (VS), including exemplary vendor shops labeled VS1, VS2, VS3 and VS4. Finally, the promenade area contains ticket office  130 , security office  140 , and first aid station  150 .  
         [0028]    Electronic displays of various types are positioned throughout public facility  100 . In the promenade area, displays D1, D2, D3 and D4 enable patrons at the concession stands or vendor shops, or waiting in rest room lines, to view the sporting event that is ongoing in the playing area. In the seating area, patrons can view displays D5, D6, D7 and D8, which typically display advertisements, scores of other sporting events, player statistics, audience greetings, and the like  
         [0029]    Each of entry point terminals EPT1, EPT2, EPT3 and EPT4 is disposed next to one of four entrances to public facility  100 . EPT1, EPT2, EPT3 and EPT4 are capable of detecting and registering the virtual electronic tickets used by customers of public facility  100 . EPT1-EPT4 read at least the encrypted authentication information from the virtual ticket device and authorize the customer to enter public facility  100 . Each one of EPT1, EPT2, EPT3 and EPT4 registers the admission of each virtual electronic ticket by any one of several conventional technologies. For example, one or more of EPT1, EPT2, EPT3 and EPT4 may comprise an optical scanner that scans a bar code or a serial number displayed on the display of a virtual ticket device that stores each virtual electronic ticket. Alternatively, one or more of EPT1, EPT2, EPT3 and EPT4 may comprise a radio frequency transceiver that establishes an RF link (such as a Bluetooth connection), or an infrared (IR) transceiver that establishes an IR link, that transfers the virtual electronic ticket information from the virtual ticket device used by the customer to the entry point terminal. In still another embodiment, one or more of EPT1, EPT2, EPT3 and EPT4 may contain a slot or a similar hardware interface into which a virtual ticket device may be inserted or engaged in order to transfer the virtual electronic ticket information via a wireline connection.  
         [0030]    Additionally, a number of wireless or wireline access points (APs) are distributed throughout the seating area and the promenade area of public facility  100 . Exemplary access points labeled AP1-AP8 are shown in FIG. 1. According to an advantageous embodiment of the present invention, EPT1-EPT4 may function both as access points and as entry point terminals. AP1-AP8 provide communication channels that permit the virtual ticket devices used by customers to communicate with the electronic ticket control system associated with public facility  100 . According to an advantageous embodiment of the present invention, AP1-AP8 are radio frequency transceivers similar to the base stations of a cellular telephone system that provide two-way radio frequency (RF) communication links with virtual ticket devices within public facility  100 . Preferably, AP1-AP8 have a hand-off capability that allows a customer to roam throughout public facility  100  without losing communication with the electronic ticket control system. Advantageously, this allows the electronic ticket control system to continually track the location of each virtual ticket device in public facility  100 .  
         [0031]    Customers can use their virtual ticket devices to signal their present location within public facility  100  to friends and to locate lost family members. A network of entry point terminals may be used within public facility  100  to authorize admission to various areas such as preferred seating sections, clubs, luxury boxes, reserved rest rooms, priority parking lots, and the like.  
         [0032]    [0032]FIG. 2 illustrates virtual ticket device  200 , which is capable of interacting with an electronic ticket control system according to the principles of the present invention. Virtual ticket device  200  comprises processor  205 , memory  210 , display  220 , keypad  230 , and one or more communication interfaces, including infrared (IR) interface (IF)  260 , radio frequency (RF) interface (IF)  270 , and wireline interface (IF)  280 . Processor  205 , memory  210 , display  220 , and keypad  230  are coupled to, and communicate via, system bus  240 . Processor  205 , memory  210 , display  220 , and keypad  230  are coupled to, and communicate via, input/output (I/O) bus  250 .  
         [0033]    Processor  205  controls the overall operation of virtual ticket device  200  by executing basic operating system (O/S) program  211  in memory  210 . Memory  210  also stores graphical user interface (GUI) application program  212 , a plurality of personal digital assistant (PDA) applications  213 , downloaded venue applications  214 , and downloaded venue data files  215 . PDA applications  213  may include, for example, an e-mail application, a browser application, a calendar application, and the like.  
         [0034]    In the illustrated embodiment, virtual ticket device  200  contains three external communication interfaces, namely, infrared interface  260 , radio frequency interface  270 , and wireline interface  280 . However, not all of these external communication interfaces are necessary to the operation of the invention. For example, in an advantageous embodiment of the present invention, virtual ticket device  200  may only contain wireline interface  280  and RF interface  270 . Virtual ticket device  200  may be adapted for insertion into a cradle device that plugs into wireline interface  280  and provides virtual ticket device  200  with electrical power for recharging a battery (not shown) in virtual ticket device  200 . When virtual ticket device  200  is plugged into a cradle device, applications and data may be downloaded or uploaded via wireline interface  280 .  
         [0035]    For example, in an advantageous embodiment of the present invention, virtual ticket device  200  may be a wireless enabled electronic organizer, such as a Palm VII™ organizer. As those skilled in the art are aware, a Palm VII™ organizer (or an equivalent appliance) is capable of communicating via a wireless interface (such as RF interface  270 ) and may be mounted in a cradle device that provides wireline communication and power supply voltages to the organizer.  
         [0036]    Processor  205  executes GUI application program  212  in order to interact with the operator of virtual ticket device  200  via keypad  230  and display  220 . Normally, GUI application program  212  enables processor  205  to execute PDA applications  213  stored in memory  210 . One of these applications may include a browser application that allows virtual ticket device  200  to access via RF interface  270  or wireline interface  280  a website for a ticket agency in order to purchase a virtual electronic ticket to an event at public facility  100 . When a virtual electronic ticket is purchased in this manner, the virtual electronic ticket and other useful applications and data files may be downloaded from the ticket agency website to virtual ticket device  200  and stored in downloaded venue applications  214  and downloaded venue data file  215 .  
         [0037]    In accordance with the method of the invention the facility operator offers his customers an option to purchase in advance admission to the best seat in the facility that remains unsold and available when the customer arrives at a future event and charges the customer a small premium for this option. If the customer elects to pay for the best available seat option, then partial admission data is loaded into the virtual ticket device at the time of purchase and this data is supplemented and completed at the time of the event in a manner described below. The premium, together with the price of a general admission ticket may be charged to the customer at the time of advance purchase. When the customer enters the facility he may be charged an additional fee which depends upon the grade and location of the best available seat. Typically, the additional fee will be somewhat discounted from the price the customer would have been charged had he purchased a guaranteed ticket in advance for the same seat. As an optional feature, the customer may also specify in advance the a maximum additional amount he is willing to pay at the time of admission and the operator determines the best available seat by taking this maximum price into account. Thus, as used herein, the term “best seat available may mean the best seat within a particular price range.  
         [0038]    Downloaded venue data file  215  may be used to store such information as the virtual electronic ticket, electronic maps of public facility  100 , text information related to concession stands and vendor shops, and text information related to security and first aid at public facility  100 . Downloaded venue applications  214  may include one or more applications executed by processor  205  when the customer is at public facility  100 . In particular, downloaded venue applications  214  may include a communication application that enables processor  205  to control the operation of RF interface  270  and wireline interface  280  such that virtual ticket device  200  is capable of communicating with access points AP1-AP8 and entry point terminals EPT1-EPT4 at public facility  100 . For example, the communication application may configure RF interface  270  in virtual ticket device  200  to use the operating frequency channels and medium access control (MAC) layer protocols used by AP1-AP8 and EPT1-EPT4.  
         [0039]    [0039]FIG. 3 illustrates virtual electronic ticket  350  displayed on virtual ticket device  200  according to one embodiment of the present invention. Virtual ticket device  200  comprises display  220 , and keypad  230 . The lower portion of display  220  contains scratch pad  305  and a plurality of icons, namely icons  11 ,  12 ,  13 , and  14 . The upper portion of display  220  contains virtual electronic ticket  350 . Virtual electronic ticket  350  comprises event name field  352 , event date field  354 , venue name field  356 , seating information field  358 , ticket serial number field  360 , and bar code field  362 .  
         [0040]    The operator of virtual ticket device  200  may use a stylus or a similar device to select icons I1, I2, I3 or I4 and thereby launch one or more of PDA applications  213  in memory  210 . Additionally, the operator may use the stylus to enter text or numbers in scratch pad area  305  when executing one of PDA applications  213  that permits the entry of text data. Additionally, the buttons in keypad  230  may be used to select icons or to perform functions such as scroll up, scroll down, scroll left, scroll right and the like.  
         [0041]    When the customer approaches or enters public facility  100 , the customer turns on virtual ticket device  200  and launches the communication application in downloaded venue applications  214  that allows virtual ticket device  200  to communicate with entry point terminals EPT1-EPT4 and access points AP1-AP8 in public facility  100 . The communication application may be launched automatically simply by selecting virtual electronic ticket  350  that has been downloaded and stored in downloaded venue data files  215 . Event name field  352  contains the name of the event occurring in public facility  100 , such as “New York Knicks vs. Indiana Pacers.” Event date field  354  contains the date on which the event is occurring, such as “Nov. 13, 2001.” 
         [0042]    Venue name field  356  contains the name of public facility  100 , such as “Madison Square Garden.” Seating information field  358  contains the section, row and seat number information associated with virtual electronic ticket  350 .  
         [0043]    According to the present invention, seating information field  358  may contain a generic “best available” code or similar indicate instead of the section, row and seat number information. According to such an embodiment, when a customer initially purchases his or her ticket, the customer has the option of paying a small premium to get a virtual ticket for the best available seat. The downloaded virtual ticket stored in virtual ticket device  200  is equivalent to a general admission seat and may not contain a specific seat assignment. When the customer enters public facility  100 , if a seat better than the general admission seat is available, the location of the best available seat may be transmitted to virtual ticket device  200  an inserted into the appropriate fields in virtual electronic ticket  350 . The customer may then be charged an additional amount according to the price difference between the original general admission seat and the best available seat.  
         [0044]    If the entry point terminal contains an optical scanner, the optical scanner may scan one or both of ticket serial number field  360  and bar code field  362 . An optical character recognition application may be used to read the serial number appearing in ticket serial number field  360 . A conventional bar code scanner device may read the bar code in bar code field  362 . In either event, when virtual electronic ticket  350  is identified, the entry point terminal accesses the data base associated with the electronic ticket control system associated with public facility  100  and, if virtual electronic ticket  350  is properly authenticated, permits the customer to enter public facility  100 . The entry point terminal may produce a visible or audible signal approving entry by the customer. Alternatively, if virtual electronic ticket  350  is not authenticated, the entry point terminal may generate an audible or visual alarm alerting a nearby gate attendant that the customer should not be admitted to public facility  100 .  
         [0045]    [0045]FIG. 4 illustrates electronic ticket control system  400  according to one embodiment of the present invention. Electronic ticket control system  400  comprises communication interface  405 , processor  410 , database (DB)  415 , and memory  430 . Processor  410 , database (DB)  415 , and memory  430  are coupled to, and communicate via system bus  420 . Communication interface  405  has an external network connection that interfaces with network bus  490 . Communication interface  405  enables processor  410  to communicate with exemplary access points AP1-AP8 and exemplary entry point terminals EPT1-EPT4. Communication interface  405  also enables processor  410  to communicate with remote servers and other devices via the Internet.  
         [0046]    Memory  430  stores site map file  432 , communication application program  434 , virtual ticket records  440 , and active virtual ticket devices file  450 . Virtual ticket records  440  contains a plurality of virtual ticket data records  441 - 443 , which are arbitrarily labeled VT1 DATA, VT2 DATA and VT3 DATA, respectively. Site map file  432  may comprise, among other things, a master seat list of every seat in public facility  100 , including a flag indicator for each seat indicating whether or not the seat has been sold or is still available. Virtual ticket records  440  comprises a master list of all virtual tickets that were sold to the particular event occurring at public facility  100 . Each virtual ticket data record  441 - 443  contains the serial number or bar code of each virtual ticket, the section and seat number information associated with each virtual ticket (or a code indicating that the virtual ticket is for a “best available” seat), payment information (optionally), the privileges associated with each virtual ticket, and the like. The virtual tickets that are received from the virtual ticket devices are compared to the virtual ticket data in virtual ticket records  440  before admitting each customer to public facility  100 . If a customer has purchased a best available virtual ticket, electronic ticket control system  400  can determine from the master seat list stored in site map file  432  which seat is the best unsold seat and can transmit the corresponding seat information to virtual ticket device  200 .  
         [0047]    Virtual ticket data records  441 - 443  may be downloaded via the Internet from a server associated with a ticketing agency that sells tickets to events held at public facility  100 . Alternatively, electronic ticket control system  400  itself also may function as a server that potential customers may access over the Internet in order to buy virtual tickets. As each virtual ticket is sold to a potential customer, electronic ticket control system  400  creates and stores a corresponding virtual ticket data record  441  and transmits the electronic virtual ticket over the Internet to the customer.  
         [0048]    Active virtual ticket devices file  450  contains virtual ticket device records  451 - 453  associated with virtual ticket devices that are in active communication with electronic ticket control system  400 . After each received virtual ticket is received and authenticated, a virtual ticket device record for the corresponding virtual ticket device that has been admitted is created in active virtual ticket device file  450 . Virtual ticket device records  451 - 453  are arbitrarily labeled VT DEVICE 1, VT DEVICE 2, and VT DEVICE 3, respectively. Exemplary virtual ticket device record  451  comprises virtual ticket (VT) identification (ID) data field  461 , privileges field  462 , and location field  463 . Database  415  normally holds the master copies of all of the information stored in memory  430 . However, the information in database  415  is loaded into memory  430  for processing by processor  410 .  
         [0049]    Site map file  432  contains electronic map data that may be downloaded to virtual ticket device  200  in order to display the location of the seat corresponding to a particular virtual ticket. The electronic map data also may illustrate the locations of the rest rooms, concession stands, vendor shops, ticket office  130 , security office  140  and first aid station  150 . Virtual ticket identification field  461  identifies the virtual ticket associated with virtual ticket device record  451 . Privileges field  462  indicates the restricted areas in public facility  100  to which the virtual ticket gains admission. For example, privileges field  462  may indicate which restaurants and luxury boxes the user of a particular virtual ticket may enter. Finally, location field  463  indicates the current location of virtual ticket device  200 .  
         [0050]    [0050]FIG. 5 depicts flow diagram  500 , which illustrates the operation of electronic ticket control system  400  and portable virtual ticket device  200  according to one embodiment of the present invention. Initially, electronic ticket control system  400  receives a request for a virtual ticket from virtual ticket device  200 . This request may be received via the Internet or via a telephone connection. In response, electronic ticket control system  400  transmits a virtual ticket to virtual ticket device  200 . Alternatively, electronic ticket control system  400  may receive a virtual ticket data record for an already issued ticket from a remote ticket agency via the Internet (process step  505 ).  
         [0051]    When the user finally arrives at public facility  100  to attend the event, virtual ticket device  200  transmits the virtual ticket stored in virtual ticket device  200  to electronic ticket control system  400  via an entry point terminal. Electronic ticket control system  400  then compares the virtual ticket to the virtual ticket data records  440  stored in memory  430  or database  415  (process step  510 ). If the virtual ticket is authenticated, electronic ticket control system  400  transmits an authorization message to the entry point terminal and the user is admitted.
