## Background
FIELD OF THE INVENTION
The present invention relates to the field of provision of wireless services for reservation, check-in, access control, check-out and payment, preferably for hotel customers by means of wireless application programs employing standard protocols operating on wireless user terminals provided with a wireless long or medium range communications and processing unit, such as a mobile telephone, and wireless short range device, such as a device complying with the Bluetooth industry standard.
The Problem Areas.
The invention addresses the following problem areas:

    
    
        The problem of a traveller on the move to find a suitable hotel, particularly in foreign cities.
        The problem of a traveller on the move who has to rely on the opening hours of travel agencies for finding hotels.
        The problem of a traveller on the move of sitting in long and costly telephone ‘waiting lines’ with travel agencies to make hotel reservations.
        Hotels difficulties in reaching the customers directly when they are looking for hotels in given areas.
        Hotels challenge in building loyalties with frequent travellers.
        Problems related to long check-in and/or check-out lines in many hotels for guest check-in, check-out and bill settlement.
        Problems related to operation of locks requiring manual operations.

Known Solutions and Problems with These.

    
    


When wanting to book a hotel room, travellers often find themselves in long travel agency telephone ‘waiting lines’. In addition, once a connection has been established, the communication with the travel agency agent introduces a distortion between the hotels' information and the traveller, e.g. in the understanding of hotel standard, quality, service level, etc. This occasionally makes the finding of a suitable hotel room slow, and unsafe as to whether the traveller is really getting what he/she requests. In addition the traveller is dependent on the travel agency's opening hours for the reservation/booking of hotel rooms in foreign cities.
For the hotel this also makes loyalty building and marketing to the end customer more difficult, since the travel agency, with it's agreements with different hotels, is the interface of traveller.
Norwegian patent publication no. NO 179888 to Ohrn discloses a system and method suitable for remote services searching, making reservations, ordering and confirming of orders, but does not provide for wireless registration, hotel check-in, room access control, hotel check-out and payment.
Another problem is the hotel check-in and the key for the hotel room door lock. The opening of a traditional hotel room door lock requires that the customer has been checked in through the reception desk, at which there is at times a long queue waiting for check in, very often to the business travellers annoyance and irritation. Existing hotel room door locks that can be electronically programmed from the hotel reception desk to accept only the key given to the customer. To operate the door locks, the locks require that the user inserts some form of physical key.
U.S. Pat. No. 5,614,703 to Martin et. al. discloses a system and for hotel check-in and check-out without the need for a desk clerk, wherein guest registration etc. is done by reading a card by means of a card reader, such as a magnetic credit card reader, located at the reserved hotel room.
Yet another problem is hotel check-out and payment. When leaving the hotel, the traveller often has to wait in a long check out line to settle the bill—while at times risking to be late for an important meeting or even to miss a flight.
On-line reservation/booking by means of Internet requires an Internet connection which may be a problem for the traveller when the traveller does not carry along a computer or a similar device which is capable of accessing the Internet. However, if the traveller should happen to have such a device, the start up of the device is still needed, and if the connection between the device and the Internet is made by means of a mobile telephone, a rather slow connection through a mobile phone will typically result in long connection times and, consequently, expensive phone bills. To alleviate this problem, hotel reservation/booking applications based on the Wireless Application Protocol (WAP) are also currently being developed and tested in various locations. However, to the knowledge of the applicant, none of these combine all of the following elements or services:

    
    
        Search for a hotel that matches the user's preferences
        Provision of a selection if several choices exist
        Payment integrated with the reservation/booking
        Provision of a reference number (booking token) that both serves as a receipt for accepted payment and as a key parameter in the communication protocol for door lock opening.

DETAILED DESCRIPTION OF THE EMBODIMENTS
In the following, with reference to the accompanying drawings, the invention will be explained by way of example.
In FIG. 1 is shown a simplified block diagram of an exemplary system embodying the system of invention. The exemplary system includes a plurality of portable wireless mobile terminals 1 capable of wireless communication 2 with a plurality of base stations 3 which have connections 4 to a communication network 5. Each mobile terminal 1 of the system in this example includes a typical mobile telephone and processing unit 23 provided with appropriate wireless application programs and with a connection 26 to an antenna system 27. The mobile wireless terminal 1 of the example also includes a short range wireless device 25 with a built-in antenna (not shown) and with a connection 24 to the mobile telephone and processing unit 23. The telecommunication network 5 has connections 6 to a plurality of hotel reservation/IT systems 7 and connections 11 to at least one hotel search and reservation server 12. Optionally, one or more hotel search and reservation server 12 can have direct links 17 to or be integrated with hotel reservation/IT system 7 of the system. Each hotel reservation/IT system 7 has a plurality of connections 8 to a plurality of short range wireless devices 9, wherein each wireless device 9 is provided with a connection 31 to an associated door lock 32 which can be operated by the associated wireless device 9. Optionally, the hotel reservation/IT system 7 can have connections 15 to wireless devices 16 located preferably at entrances/exits of the hotel. For wireless payment services, the system includes at least one payment server 14 with a connection 13 to the telecommunication network 5. The wireless devices 25 can communicate with in-range wireless devices 9 and 16 by means of wireless connections 10. For simplicity, in FIG. 1, only one unit or device is shown for each element, however, a typical system may equally well comprise a plurality of such units or devices.
With reference to FIG. 2, in one aspect of an embodiment of a method of the invention, the invention provides for wireless hotel reservation/booking by a user. The search for hotels and the possibility to book rooms in accordance with requirements of a user is provided through a WAP interface. The hotel reservation/booking of this example is performed mainly in two stages:

    
    
        i. the user searches for a hotel to find one that matches the required criteria;
        ii. the user makes a reservation/booking request in which the actual reservation/booking is performed.
    
    


In the first stage (i), the hotel search of the example is performed by a per se known search engine, intelligent agent or other available means which has access to one or several hotel reservation/booking systems. The user criteria for selecting a hotel can be parameters like location, price, features of the hotel etc. The user interface presented to the user on the mobile terminal can be implemented suitably by any suitable application means, e.g known application means such as WAP (WML/WML Script), typical Web applications (HTML/Java Script) or Java Application/Applet. The server side of the application can be built using by means of standard Web application models or other suitable means. In the second stage (ii) of the hotel reservation/booking, the hotel reservation/booking is performed through a wireless application that communicates with the reservation/booking system of the chosen hotel using standard mechanisms according to any suitable application means, such as Wireless Mark-up Language (WML) forms or the ones described above. The user or a user controlled application on the mobile terminal inputs the necessary data needed to perform the reservation/booking and a receipt confirming the reservation/booking is received from the reservation/booking system.
Also with reference to FIG. 2, in another aspect of an embodiment of a method of the invention, the reservation/booking receipt from the hotel reservation system contains a key token such as e.g. a reference number which can be directly used for obtaining access to the reserved room upon arrival at the hotel.
Optionally, as shown in FIG. 2, security can added to the above, e.g. through the use of PKI (Public Key Infrastructure).
Now, with reference to FIG. 3, in a further aspect of an embodiment of a method of the invention, the invention provides for wireless operation of hotel room door locks. After successful reservation, the wireless door lock system of the reserved room receives information about the valid key token, or a secret key, from the hotel reservation/IT system. By means of the short range wireless device in the mobile wireless terminal, the key token is transmitted to nearby wireless devices associated with electrically operable door locks. On receiving the appropriate key token from the wireless device in the mobile wireless terminal, the door lock wireless device of the reserved room can notify the associated hotel reservation/IT system of the arrival of the user for check-in, and unlocks the door. The user is notified of the event, and is given the opportunity to control the door lock by means of a suitable user interface on the mobile wireless terminal. A situation of use of the method explained above is also illustrated in FIG. 6.
The communication protocol between the mobile terminal and the wireless door lock system is performed over a Bluetooth, Infrared or other suitable bearer. To achieve optimal security, this information could be protected in the user's terminal by means of a PIN code, fingerprint or other local authentication methods.
The protocol as described can be implemented in several ways; as a generic protocol that uses the Bluetooth data transport directly for information exchange, or it may be implemented using e.g. WAP as a transport mechanism.
Conventional electrically operated hotel room door locks employed by a system according to the invention may be equipped with Bluetooth chips and functionality. Together with WAP mobile phones equipped with wireless Bluetooth compliant devices, this makes possible mechanisms which may provide new value added services as described below. Such mechanisms may work in the following way:
Now, with reference to FIG. 4, in yet another aspect of an embodiment of a method of the invention, the invention provides for wireless user check-out from the hotel and wireless hotel bill payment. By means of the properly adapted mobile wireless terminal, connection is made to the hotel search and reservation/booking server. While connected to the hotel search and reservation/booking server, a check-out request is communicated to the hotel reservation/IT system by means of a communications network. The hotel reservation/IT system responds by sending back bill information, and the user responds by sending a bill acceptance or rejection message. On receiving the acceptance of the user, the hotel reservation/IT system sends a payment request to the payment server which in turn sends a payment authorisation request to the user. The user then responds to the payment server by sending a payment authorisation message back to the payment server. In turn, the payment sends a payment verification message to the hotel reservation/IT system verifying that the bill has been paid electronically. Upon receiving the appropriate messages, the hotel reservation/IT system can send a key token deactivation message to the door lock associated wireless device of the reserved room.
A wireless application for service can be used for checking out of hotels and settling the hotel bill. In this way the customer will not need to wait in a check-out line at the check-out counter of the hotel before leaving the hotel. This application can be implemented as a standard “electronic commerce” type application which may additionally use information collected directly from a wireless Bluetooth-enabled door lock. From his/her application on the mobile terminal the user can initiate the proper check-out mechanism, such as e.g. if additional charges shall be incurred for late check-out. The application can use standard available secrecy and privacy mechanisms such as Secure Socket Layer (SSL), Secure Electronic Transfer (SET) or similar to protect the payment information.
Now, with reference to FIG. 5, in yet another aspect of an embodiment of a method of the invention, the invention provides for wireless user check-out from the hotel and electronic hotel bill payment. In contrast to what was explained above with reference to FIG. 4, the additional aspect of the hotel check-out and electronic hotel bill payment illustrated in FIG. 5 is the triggering of automatic check-out or generation of a payment request from the hotel reservation/IT system to the payment server after exit registration or expiration of the reservation period. If the payment is registered on or prior to the registration of exit, then the check-out is registered. If the reservation period expires and the payment is not registered on or prior to the expiration of the reservation period, then the automatic generation of the payment request can be triggered. A situation of use of the method explained above with reference to FIGS. 4 and 5 is also illustrated in FIG. 7.
With reference to FIG. 8, examples of bearers such as the standardised UMTS, GSM, TDMA and/or CDMA which can be employed by the Wireless application for mobile terminals and associated mobile networks in a system according to the invention is shown.
Other Useful Aspects of the Invention.
Using a wireless application reservation service for flight tickets combined with the use of the Bluetooth technology, the customer will not need a flight ticket, and the Bluetooth phone could even be the ‘boarding pass’ letting the traveller through the boarding gate of an airport. The same principle can be used in cinemas, mueseums, concerts and other such venues requiring a pass for entering.
Adding the use of automatic mobile localising applications will enable features as ‘show me the nearest hotel (corresponding to my preferences)’. It will also enable services like supplying a digital map of how, and by what means of transportation, to get to the hotel from where the traveller is—together with the room confirmation.
By using wireless devices complying with the Bluetooth technology industry standard in conjunction with house door locks, the door may e.g. be locked at all occasions, except for when someone living in the house, and whose identity in accordance with the Subscriber Identity Module (SIM) of the mobile wireless terminal has been programmed into the lock, is approaching—then the door lock unlocks automatically. For the user, there will be no need to pick up keys when carrying shopping bags or small children—the user can just walk right in, or out. Combined with a motorised door opener, a secure hands-free door opening system can be provided, to the advantage of people in general and in particular for disabled persons. In addition, such wireless locks could also be opened using Bluetooth ‘keys’, traditional keys and/or special Bluetooth ‘key’ devices with built in Bluetooth technology.
In intelligent homes the unlocking and locking of the entrance door could also be combined with an alarm, with a function telling the residensee about unlocked windows or terrace doors, or even with a function that will automatically lock all windows and terrace doors when the last residensee holding a Bluetooth equipped phone or ‘key’ is leaving the house.
Car door locks can be equipped with wireless locks according to the invention. With wireless locks employing Bluetooth technology, the mobile phone may also function as a starter key—with Bluetooth connection; all that's needed is to push a button on the terminal to start the engine. Without the Bluetooth connection there will be no possibility to start. Thus, this also provides increased car theft protection.
The invention, and in particular the wireless hotel search and reservation/booking, makes it possible for hotels and hotel chains to get closer to the customer and to easier build loyalties with the customers. For the travellers it means a considerable improvement in ease of finding a suitable hotel—also when visiting a city for the first time, or e.g. when the favourite hotel is fully booked.
For the hotels this is a possibility to provide value added services, and for building customer loyalty—the customer will have his/her favourite hotel or hotel chain WAP reservation address programmed into the mobile phone, knowing that upon arrival, after making a reservation through the WAP hotel room reservation service, all he/she needs to do is to walk right up to the room that's been prepared for his/her arrival. The service also opens the door for the hotel(s) to keep track of the customer's preferences and customer profile, thus making it possible for the hotel(s) to tailor services for loyal customers.
A system according to the invention can be set to terminate the function of the Bluetooth phone as a key for the hotel room door lock after the customer exits the room after payment, after the customer leaves the hotel after payment, or after a certain time of the departure day, depending on the hotel wishes. For travellers in hurry, it will even be possible to settle the bill after the departure from the hotel, by use of the WAP check out and payment service. The service may have built in functions that prevent customers from escaping from hotel bills. If the customer has not actively settled the bill the WAP check out and payment service may prompt the customer to do so after a certain hour of the check out day. If the customer has still not settled the bill after a certain, pre-set time, the bill will be automatically settled through the chosen electronic payment method.
Advantages
With the WAP hotel room reservation service the customer can be able to choose the hotel corresponding the best to his/her requirements. The WAP hotel room reservation service may, upon or in conjunction with confirmation of the reservation, send a message to the phone, including the hotel room number. Thus, even before the arrival at the hotel, the customer may know which room he/she has been assigned, and is then able go directly to the room without having to make a check-in at the reception desk of the hotel.
When the traveller approaches the hotel room, the hotel room door lock senses, by means of the wireless Bluetooth technology, the WAP and Bluetooth enabled mobile terminal, and when a security code is implemented, the latter provided either through the WAP reservation service and stored in the mobile terminal, or from the customers unique SIM card identity, and registered with the hotel, compares it with a security code automatically programmed into the lock through the WAP hotel room reservation service, and opens the door. When unlocking the door in this way for the first time at each stay, the check-in at the hotel may be automatically registered by the hotel reservation/IT system. In this way, the customer's mobile terminal functions as a wireless unique electronic key to his/her room until checking out, and at that time the WAP check-out and payment service may be used.
When the customer is leaving the hotel he/she can settle the bill by means of a WAP check-out and payment service provided by the system. The service will make it possible for the customer to check the bill before leaving, and to approve payment of it. The payment can be done through any electronic payment method chosen in the service implementation (if more than one method is available, the customer preferably chooses the preferred method of payment at the time of reservation of the hotel).
Using this invention, a WAP and Bluetooth equipped mobile terminal, and the associated WAP services, the customer experiences an immense increase in ease and flexibility of hotel reservation and in ease of finding hotels and rooms that correspond to personal and corporate requirements. In addition the customer avoids both check in and check out queues. The customer will thus enjoy increased flexibility and ease of use when staying at hotels providing this service.
