`BACKGROUND OF THE INVENTION
`
`(1) Field of the Invention
`The present invention relates to a device and in particular
`but not exclusively to a device Which provides access to an
`entity.
`(2) Description of Related Art
`Including information disclosed under 37 CFR 1.97 and
`1.98;
`Wireless cellular netWorks are knoWn in Which the area
`covered by the netWork is divided into a number of cells. Each
`cell is served by a base transceiver station. The base trans
`ceiver station is arranged to communicate With mobile sta
`tions in the cell associated With the base station. The mobile
`stations establish via the base station a connection With
`another user, a ?xed line telephone or the Internet.
`Programmable keys are knoWn. For example, plastic cards
`With magnetic strips are used as keys to open locks to for
`example doors or the like. The use of such keys is disadvan
`tageous in that different keys are provided to access different
`entities and therefore need to be carried by the user.
`It has been proposed to alloW multiple users access to the
`same entity. For example, a front door to an o?ice may be
`accessed by a number of users or a hotel room may be
`accessed by different users at different times. It is necessary
`for the accessed entity to have a database or similar to keep a
`record of the authorised users. It is disadvantageous if a
`database or similar needs to be associated With the accessed
`entity. For example, in a hotel, to have a database associated
`With each lock Would be costly.
`It is an aim of embodiments of the present invention to
`address one or more of the problems discussed earlier.
`
`BRIEF SUMMARY OF THE INVENTION
`
`According to a ?rst aspect of the present invention there is
`provided an access device comprising means for receiving a
`key and validity information, Wireless communication means
`for establishing a connection With another party, said Wireless
`communication means being arranged to provide said key and
`said validity information to said another party, Wherein if said
`key and said validity information are determined by the
`another party to be valid access is provided.
`According to a second aspect of the present invention there
`is provided an access method comprising the steps of receiv
`ing a key and validity information, establishing a Wireless
`connection With another party, providing said key and said
`time related information to said another party, and checking at

`
`BRIEF DESCRIPTION OF THE SEVERAL
`VIEWS OF THE DRAWING(S)
`
`For a better understanding of the present invention and as to
`hoW the same may be carried into effect, reference Will noW
`be made by Way of example to the accompanying draWings in
`Which:
`FIG. 1 shoWs a schematic diagram of a cellular netWork;
`FIG. 2 shoWs a block diagram of a mobile station embody
`ing the present invention;
`FIG. 3 shoWs a block diagram of the entities With Which the
`mobile station communicates;
`FIG. 4 shoWs the Bluetooth device of FIG. 3 in more detail;
`and
`FIG. 5 illustrates the method embodying the present inven
`tion.
`Reference is made to FIG. 1 Which shoWs a cellular net
`Work 2. The area covered by the netWork 2 is divided into a
`plurality of cells 4. Three cells 4 are shoWn in FIG. 1. HoW
`ever, it should be appreciated that in netWorks there Will
`typically be many more cells.
`Each cell 4 has associated thereWith a base transceiver
`station 6. Each base transceiver station 6 is arranged to receive
`signals from and send signals to mobile stations 8 in the cell
`associated With the base station 6. Depending on the method
`of communication, the mobile stations may communicate
`With the base stations of adjacent cells. In some embodiments
`of the present invention, a mobile station may be able to
`communicate With tWo or more base stations at the same time.
`The mobile stations and base transceiver stations typically
`use radio frequency signals to communicate. The base sta
`tions and mobile stations may use a frequency division mul
`tiple access technique. This means that the available fre
`quency spectrum is divided up into a number of bands and the
`mobile station Will be allocated a given frequency to commu
`nicate With the base station With the base station being allo
`cated another frequency to communicate With the mobile
`station. Generally, the frequencies Will be different but this is
`not essential. The mobile stations and the base stations may
`use a time division multiple access technique. With this
`method, a frequency band is divided up into a number of time
`slots and a mobile station is allocated a given one of those
`time slots to communicate With the base station and vice
`versa. In the GSM (global system for mobile communication)
`standard, a combination of frequency division multiple
`access and time division multiple access is used. Spread spec
`trum techniques such as code division multiple access may
`also be used. In this technique, different spreading codes are
`used by different mobile stations so that the signals from the
`different mobile stations can be distinguished. Similarly, the
`different base stations Will use different spreading codes. In
`the third generation system, a Wideband CDMA system has
`been proposed. It should be appreciated that in embodiments
`of the present invention, any of these techniques may be used
`either on their oWn or together. It is of course possible that any
`other suitable techniques may be used.
`
`DETAILED DESCRIPTION OF THE INVENTION
`
`Reference is noW made to FIG. 2 Which shoWs a block
`diagram of a mobile station embodying the present invention.
`The mobile station 8 has a ?rst antenna 10. The ?rst antenna
`10 is arranged to receive signals from the respective base
`
`UniKey Exhibit 1006, Page 5
`
`

`

`US 7,873,989 B2
`
`3
`transceiver station 6. The ?rst antenna 10 is also arranged to
`transmit signals to the base station 6.
`The signals received by the ?rst antenna 10 are forwarded
`to a radio frequency transceiver 12. The radio frequency
`transceiver 12 Will doWn convert the radio frequency signals
`to a baseband frequency. The radio frequency transceiver may
`perform other functions such as decoding, demodulation or
`the like. The received information at the baseband frequency
`is forWarded by the radio frequency transceiver 12 to a pro
`cessor 14 Which extracts the necessary information from the
`received signal. The processor 14 may be arranged to provide
`an output Which is connected to a speaker Which may provide
`received voice signals. The processor 14 may receive control
`information from the base station Which is used to control the
`mobile station or the like. The processor 14 may also extract
`information Which is to be displayed and display that infor
`mation on a display 16. The processor may also receive an
`input from a user interface such as a keyboard or the like.
`The processor 14 is also used to process signals to be
`transmitted by the ?rst antenna 10 and may also receive an
`output from for example a microphone or the like. The signals
`Which are to be transmitted by the ?rst antenna are output by
`the processor 14 at the baseband frequency. The radio fre
`quency transceiver 12 upconverts the baseband signals to the
`radio frequency and forWards them to the ?rst antenna 10 for
`transmission. The radio frequency transceiver may encode
`the information, modulate it or carry out any other processing
`of the signal.
`The radio frequency transceiver 12 may be connected to a
`memory 18. The memory 18 is arranged to store some infor
`mation received by the radio frequency transceiver. In alter
`native embodiments of the present invention, the memory
`may be connected to the processor 14 and so may receive
`information via the processor.
`The mobile station 8 has a second antenna 20. The second
`antenna is arranged to receive and transmit signals in the
`BLUETOOTH Wireless PC card range of frequencies.
`BLUETOOTH Wireless PC card is a standard Which has been
`proposed for short range, loW poWer, high frequency signals.
`Typically, the signals Will be of the order of a giga Hertz. The
`second antenna 20 is arranged to receive BLUETOOTH Wire
`less PC card signals from a BLUETOOTH Wireless PC card
`device. The signals received by the second antenna are for
`Warded to a BLUETOOTH Wireless PC card transceiver 22.
`The BLUETOOTH Wireless PC card transceiver 22 performs
`similar functions to the radio frequency transceiver 12. In
`particular, the BLUETOOTH Wireless PC card transceiver 22
`doWnconverts the received signals to a baseband frequency. If
`required, the BLUETOOTH Wireless PC card transceiver
`may demodulate and decode the received signal. The received
`signals may be forWarded to the processor 14 for further
`processing.
`The BLUETOOTH Wireless PC card transceiver 22 is also
`arranged to receive information from the processor 14. The
`received information is at the baseband frequency, and the
`BLUETOOTH Wireless PC card transceiver upconverts the
`signals to the BLUETOOTH Wireless PC card frequency so
`that they can be transmitted by the second antenna. If
`required, the BLUETOOTH Wireless PC card transceiver 22
`Will modulate, encode and perform any other required func
`tion.
`The BLUETOOTH Wireless PC card transceiver 22 is
`arranged to have access to the memory 18 and can retrieve
`information stored therein. In alternative embodiments of the
`present invention, the information may be retrieved by the
`processor from the memory and forWarded to the BLUE
`TOOTH Wireless PC card transceiver 22.

`Reference Will noW be made to FIG. 3, Which schemati
`cally illustrates embodiments of the present of the present
`invention. The mobile station 8 is arranged to have a BLUE
`TOOTH Wireless PC card connection With a BLUETOOTH
`Wireless PC card device 24. This means that signals are
`exchanged betWeen the mobile device and the BLUETOOTH
`Wireless PC card device in accordance With the BLUE
`TOOTH Wireless PC card standard. With the BLUETOOTH
`Wireless PC card standard, tWo devices are able to communi
`cate directly Without going via, for example, a base station.
`In embodiments of the present invention, it is proposed that
`the BLUETOOTH Wireless PC card device be a lock or an
`access device. For example, the BLUETOOTH Wireless PC
`card device may be provided on a hotel door. The
`BLUETOOTH Wireless PC card device may be part of an
`access device. For example, the access device 24 may permit
`access to a cinema, public transport, a ski lift or the like.
`Alternatively, the BLUETOOTH Wireless PC card device
`may, for example, be incorporated in a rental car or the like.
`Embodiments of the present invention are particularly suit
`able for alloWing access to a given user temporarily. HoWever,
`embodiments of the present invention can be used in other
`situations.
`The communications betWeen the mobile device and the
`BLUETOOTH Wireless PC card device 24 are via the second
`antenna 20 of the mobile station 8.
`Reference is made to FIG. 4, Which shoWs the BLUE
`TOOTH Wireless PC card device 24 of FIG. 3 in more detail.
`The BLUETOOTH Wireless PC card device 24 has an
`antenna 26. This antenna 26 is arranged to receive and trans
`mit signals at the BLUETOOTH Wireless PC card frequency.
`More particularly, the antenna 26 is arranged to transmit
`signals to the second antenna of the mobile station and to
`receive signals therefrom. The BLUETOOTH Wireless PC
`card device has an upconverter 28. The upconvertor 28 is
`arranged to upconvert signals from a baseband frequency to
`the BLUETOOTH Wireless PC card frequency for transmis
`sion by the antenna 26. The upconverter 28 may carry out
`other functions such as modulation, encoding or any other
`suitable function.
`The signals Which are received by the antenna 26 are pro
`cessed by a doWnconver‘ter 30 Which reduces the frequency of
`the received signals from the BLUETOOTH Wireless PC card
`frequency to the baseband frequency. Again, the doWncon
`verter 30 may perform other functions such as demodulation
`or decoding.
`The signals Which are received by the antenna 26 and doWn
`converted by the doWnconver‘ter 30 are output to a processor
`32, Which is able to process the received signals further.
`LikeWise, the processor 32 is arranged to output those signals
`Which are to be transmitted to the upconverter 28. The BLUE
`TOOTH Wireless PC card device 24 also has a memory 32
`Which is used to store information. This Will be described in
`more detail hereinafter.
`Referring back to FIG. 3, the mobile station is also able to
`communicate With the base transceiver station 6 using the ?rst
`antenna 10. The base transceiver station provides a connec
`tion to other elements of a netWork 36. The netWork 36 is
`connected to a gateWay element 38 Which, usually is part of
`the netWork 36. The gateWay element 38 alloWs the netWork
`to be connected to an external entity, such as another netWork,
`the Internet or a server 40 of a service provider.
`Reference Will noW be made to FIG. 5, Which shoWs a How
`diagram of the steps of the method embodying the present
`invention and illustrates hoW embodiments of the present
`invention Work. The mobile station 8 is arranged in step S1 to
`establish a connection With the netWork 36 via the base trans
`
`UniKey Exhibit 1006, Page 6
`
`

`

`US 7,873,989 B2
`
`5
`ceiver station 6. In the embodiment described, the mobile
`station is a WAP (Wireless application protocol) mobile sta
`tion. However, it should be appreciated that the mobile device
`may be in accordance With any other protocol and may, for
`example, be able to use the short message servicing SMS
`feature in embodiments of the invention. The network is also
`arranged to establish via the gateWay 38 a connection With a
`server. This server 40 is associated With the service provider.
`For example, if embodiments of the present invention are to
`be used to alloW access to hotel rooms, then the server 40
`Would be associated With the hotel. As an alternative, the
`mobile station 8 could also access the server provider via
`BLUETOOTH Wireless PC card transceiver connected to the
`server. In this Way, the mobile station can get the key over the
`BLUETOOTH Wireless PC card connection Without the need
`for netWork connection. Cost Would also be reduced. If, hoW
`ever, an order for a service (for example a hotel room) Was
`made in advance, the key could be obtained remotely via the
`base transceiver station 6 using WAP and SMS.
`In the second step S2, the server 40 provides the mobile
`station With key information and additional information. For
`example, in the context of a hotel, the additional information
`could take the form of the hotel room. In this particular
`embodiment, the key and additional information are doWn
`loaded to the mobile station in the same call Where the mobile
`station establishes the connection.
`HoWever, in alternative embodiments of the present inven
`tion, it is possible that the mobile station in step 1 establish a
`WAP connection and provides an indication to the server as to
`the particular service required. The server may then cause the
`mobile station to be called back With the required key and
`additional information.
`The key information Which is sent to the mobile station is
`usually encrypted. The Whole of the key may be encrypted or
`only part of the key may be encrypted. In alternative embodi
`ments of the present invention, the key may not be encrypted.
`If the key is encrypted, the mobile station may be able to
`decrypt all or part of the key information. HoWever, in pre
`ferred embodiments of the present invention, the mobile sta
`tion is not able to decrypt the key information. The additional
`information Which is sent to the mobile station may also be
`encrypted but this is not necessary. Where this additional
`information is encrypted, the mobile station Will usually be
`able to decrypt that information. For example, if the addi
`tional information relates to a room key, the user Will need to
`knoW Which hotel room the user is alloWed access to. This
`additional information may be communicated to the user. For
`example, the information may be displayed on the display or
`may take the form of a voice message. Once the additional
`information has been received by the mobile station, the
`connection With the server 40 is terminated.
`In the next step S3, the mobile station is arranged to estab
`lish a BLUETOOTH Wireless PC card connection With the
`BLUETOOTH Wireless PC card device 24. The connection
`With the BLUETOOTH Wireless PC card device 24 can take
`place some time after the ?rst tWo steps are being completed.
`As indicated previously, BLUETOOTH Wireless PC card is a
`standard Which has been proposed to permit the direct com
`munication betWeen tWo devices. One feature of the BLUE
`TOOTH Wireless PC card standard is that each packet is
`transmitted With a different frequency.
`Once the BLUETOOTH Wireless PC card connection has
`been established, in step S4 the mobile station sends the key
`information to the BLUETOOTH Wireless PC card device.
`This may be in response to a request from the BLUETOOTH
`Wireless PC card device for the key.

`In the step S5, the BLUETOOTH Wireless PC card device
`Will check the validty of the key. In particular, the BLUE
`TOOTH Wireless PC card device attempts to decrypt the keys
`and Will compare it With key information Which it has stored
`thereon.
`In step S6, if the key is valid, then the BLUETOOTH
`Wireless PC card device 24 Will provide access for example to
`the room.
`In the embodiments of the present invention, it is envisaged
`that the mobile station could be used to store more than one
`key. So that the BLUETOOTH Wireless PC card device 24 is
`able to receive the correct key, it is preferred that each key has
`an identi?cation tag Which identi?es the service provider. The
`BLUETOOTH Wireless PC card device Would in its request
`sent to the mobile station for the key include this information
`identifying the associated service provider. The mobile sta
`tion Would then only send the key(s) Which have the tag
`associated With the given service provider. Where a number
`of different keys are associated With the give service provider,
`the BLUETOOTH Wireless PC card device could try all of the
`keys to see Which one matches. It is of course possible in
`embodiments of the present invention that each BLUE
`TOOTH Wireless PC card device has a unique identity tag so
`that the mobile station only sends the key Which matches that
`identity tag provided by the BLUETOOTH Wireless PC card
`device.
`In alternative embodiment of the present invention, the
`mobile station may provide all of the keys Which it has to the
`BLUETOOTH Wireless PC card device Which Will then test
`all of them in order to determine Which key is the correct key.
`This may be less preferable to those embodiments Where
`security is of importance.
`The key may have a time limit beyond Which it is not valid.
`For example, a hotel room key may be only valid for the time
`that the user stays in the hotel. Accordingly, in some embodi
`ments of the present invention, time information may form
`part of the key. Alternatively, there may be separate informa
`tion provided relating to time information. The BLUE
`TOOTH Wireless PC card device, When determining if the key
`is valid or not, Will check to see Whether or not the key is still
`valid. The time information may take any suitable format
`such as a start time and/or an end time or any other suitable
`format. For this, the BLUETOOTH Wireless PC card device
`Will require access to a clock. That may be part of the BLUE
`TOOTH Wireless PC card device itself or the information may
`be provided by the mobile station.
`In embodiments of the present invention, asymmetric
`encryption or symmetric encryption may be used. With sym
`metric encryption, the same key is used for encrypting as for
`decrypting. With asymmetric encryption, different keys are
`used for encryption and decryption. For example, public and
`private keys may be used. Thus, the data may be encrypted
`With a public key Which is Well knoWn and decrypted With a
`private key Which is only knoWn to a given user. It should be
`appreciated that any suitable form of encryption and decryp
`tion could be used.
`In order to further increase the security, a hash code can be
`applied to the key data.
`It should be appreciated that any suitable Way of transmit
`ting key data securely betWeen the server, the mobile station
`and the BLUETOOTH Wireless PC card device may be used.
`In many of these forms the BTS and GW Would not be
`needed.
`In embodiments of the present invention, the mobile device
`has been described as being a mobile station. It should be
`appreciated that any suitable device can be used. For example,
`items such as Wrist Watches could be modi?ed so as to provide

`the functions of the embodiments of the present invention.
`Indeed, dedicated devices may be provided in order to per
`form the functions of embodiments of the invention. It has
`been proposed to provide a credit card type device Which has
`the capability of making radio connections. Embodiments of
`the present invention may be incorporated in such devices.
`In embodiments of the present invention, the mobile station
`has been described as using the BLUETOOTH Wireless PC
`card protocol. HoWever, in alternative embodiments of the
`present invention, different radio frequencies can be used. For
`example, infrared, Wireless LAN and HomeRF could be used
`instead of the BLUETOOTH Wireless PC card.
`Embodiments of the present invention may be used in a
`Wide range of situations. For example, the mobile station 8
`may receive from the server a ticket for a sporting event,
`theatre or cinema. The mobile station may receive from the
`server a key Which alloWs a rented car to be driven. The
`mobile station may receive tickets Which alloW the user to
`travel on public transport such as aeroplanes, buses or trains.
`Embodiments of the present invention may be arranged to
`provide access to for example ski lifts. Embodiments of the
`present invention are particularly applicable to the provision
`of temporary access for example to a hotel or access to a
`cinema. HoWever, embodiments of the present invention can
`be used to permit a user to obtain access to more permanent
`services. For example, embodiments of the present invention
`can be arranged to alloW a user to access their o?ice or home.
`The additional information Will be appropriate for a par
`ticular service. In the context of a hotel room, the additional
`information Will take the form of the room number. In the case
`of car rental, the additional information Will take the form of
`the registration number of the car and/or a reference. In the
`case of tickets to an event, the information may take the form
`of the seat information. The additional information may also
`provide time information. For example, the amount of time
`for Which a hotel room is available may be included. In
`embodiments of the present invention, the same technique
`can be used to obtain more user time. For example, in the case
`of a rental car the user may use the same technique in order to
`obtain a longer rental time.
`In embodiments of the present invention, there is no need to
`connect each of the BLUETOOTH Wireless PC card devices
`together to a central control element. This is because of the
`provision of information relating to the time for Which the key
`is valid. In the case of a lock, the key used by the lock does not
`have to be continually changed. For example, a hotel room
`may be validly opened by a user one day, but if the user has not
`requested the room for an additional day, the user Will not be
`permitted to enter that room on the next day. Thus, the need
`for additional infra structure connecting the BLUETOOTH
`Wireless PC card devices can be avoided. The validity time for
`the key can be in the non-encrypted part of the key so that the
`mobile station can remove it automatically. Also, this Would
`alloW the BLUETOOTH Wireless PC card device to send a
`request to the mobile station to remove the key. As an alter
`native, rather that a valid time information, any other validity
`information indicating the validity of the user or validity of
`the use of the item being accessed can be transferred. For
`example, a maximum speed for a hire car during use could be
`stipulated.
`The access key is stored in the memory 18 of the mobile
`station. Alternatively, the access key may be stored in an
`integrated part of the device for example on a smart card. The
`key information is also stored in the memory 34 of the BLUE
`TOOTH Wireless PC card device. Again, the information may
`be stored in any other suitable location in the BLUETOOTH
`Wireless PC card device.

`Mobile stations or devices embodying the present inven
`tion may store any number of different keys for different
`purposes.
`In alternative embodiments of the present invention, the
`mobile station may be arranged to provide the BLUETOOTH
`Wireless PC card device With user identi?cation information.
`This may be part of the key or separate therefrom. This
`information can be used to provide additional security. For
`example, in the car rental situation, the user may be required
`to identify himself by entering a personal identi?cation num
`ber code to prevent misuse or crime. Additionally, the key
`may be stored in the part of the memory Which requires the
`user to enter their personal identity number (PIN). Without
`the PIN the mobile station Will not send the key. Additionally,
`each key can be provided With its oWn PIN. The user needs to
`knoW the PIN in order to use the key. The mobile station sends
`the key together With the PIN (the PIN could be, for example,
`part of the key for decryption). Furthermore, no PIN might be
`required.
`It is preferred that the validity time for the key be
`encrypted. This means that the mobile station can automati
`cally delete those keys Which are out of date.
`The keys are preferably stored in a tamper proof memory
`Which may be an ASIC, smart card or the like.
`In alternative embodiments of the present invention, a
`single antenna may be provided in the mobile station and the
`key information and the like may be provided to the mobile
`station using the same antenna Which is used to send the key
`information to the accessed entity. That single antenna may
`be arranged to use the BLUETOOTH Wireless PC card stan
`dard or the usual mobile station frequencies.
