The present invention relates to communication devices and a method of communication. In particular, but not exclusively, the present invention relates to wireless communications devices and a method of wireless communications.
It has been proposed to use mobile stations instead of credit cards at a point of sale. In this proposal, it has been suggested that a wireless link be established between the point of sale device and the mobile station. The mobile station may provide the point of sale device with similar information to that provided by a credit card.
One problem with this proposal is how to ensure that the correct mobile station is connected to the point of sale device. For example, in a busy supermarket, there may be a large number of point of sale devices and a large number of mobile stations. It is important that the right point of sale device be connected to the right mobile station. Clearly, considerable problems would be caused if the wrong mobile station was connected to the wrong point of sale device. The user of a mobile station could be charged for goods not purchased by the user.
It is an aim of embodiments of the present invention to address the above problems.
According to one aspect of the present invention, there is provided a portable communications device comprising communication means for communicating with a another party, and identification means for separately providing information on said device, said another party being arranged to obtain said information from said identification means and to use said information to establish communication with said communication means.
The identification means may comprise a bar code, a radio frequency tag or a magnetic data carrying arrangement. The bar code may be arranged on the exterior of the communications device or may be displayed on a display of the communications device. The magnetic data carrying arrangement may comprise a magnetic strip.
The information provided by said identification means may comprise one or more of the following: identity of the device; address of the device when the communication means are used and identity of the user.
The third party may be one of the following devices: point of sale device; ticket sale device; and information kiosk.
The link with the another party may be a wireless link. The wireless link may be a high frequency link, for example of the order of giga Hertz. The wireless link may be a Bluetooth link. Alternatively, the wireless link may be an infra red link. The communications device is preferably a mobile telephone.
According to a second aspect of the present invention, there is provided a communications device comprising communication means for communicating with a portable party, and identification means for separately providing information on said device, said portable party being arranged to obtain said information from said identification means and to use said information to establish communication with said communication means.
According to a third aspect of the present invention, there is provided a method of establishing a communications connection between a portable communications device and another party, said method comprising one of said another party and said portable communications device obtaining information from the other of said another party and said portable communications device; and using said information to separately establish communications between said another party and said communications device.
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 only to the accompanying drawings in which:
Reference is made to
The cellular network 2 can use any suitable method of communication. Known methods of communication include those based on time division multiple access, frequency division multiple access and spread spectrum techniques such as code division multiple access. Hybrids of two or more of these access techniques can also be used. In the following description, the mobile station is described as operating in accordance with the UMTS (Universal Mobile Telephone System) standard, which uses code division multiple access. However, the mobile station can operate in accordance with any other suitable standard, for example GSM (Global System for Mobile Communications). GSM uses a tirne/frequency division multiple access technique.
Reference will now be made to
The service access point 10 has an antenna 12. The antenna 12 is arranged to receive signals from a mobile station. The received signals are passed to a wireless link 14. The wireless link processes the received signals and puts the received data into a format which can be used by the main part 16 of the service access point. The wireless link may convert the received signal to a base band frequency and may carry out decoding and demodulation, as is well known.
The antenna 12 is also arranged to transmit signals to a mobile station. The wireless link 14 receives the data to be transmitted and puts it into a format suitable for transmission. The wireless link 14 may up convert the signals, encode and modulate the data before passing it to the antenna 12 for transmission.
The service access point 10 also comprises a reader 18. The reader 18 is arranged to read information provided by a mobile station 8. This will be described in more detail hereinafter.
The structure of the mobile station 8 is shown in
The UMTS transceiver also receives data from the processor 26 which is to be transmitted by the mobile station. The UMTS transceiver 24 encodes, modulates and up converts the signal to the radio frequency which is to be used. The radio frequency signal is then transmitted by the antenna 20.
The second antenna 22 is connected to a Bluetooth transceiver. Bluetooth is a proposed new standard that uses relatively low power radio frequency signals. The frequency may be in the GHz range. This is quite different to the UMTS frequencies. For this reason, separate antennas 20 and 22 are usually provided for the two different types of signal. The Bluetooth transceiver 28 receives Bluetooth frequency signals from the second antenna 22 and decodes, demodulates and down converts those signals. The data output by the Bluetooth transceiver 28 is input to the processor 26. The processor 26 is also arranged to provide data to the Bluetooth transceiver 28 which is to be transmitted by the Bluetooth antenna 22. This data is up converted to the Bluetooth frequency, modulated and encoded before being transmitted by the second antenna 22.
The mobile station 8 also has a display 30. The display is controlled by the processor 26 and provides information for the user. A keypad 32 is provided to allow the user to input numbers and other information. The information input via the keypad 32 is input to the processor 26 which may be controlled in accordance with the input information. The mobile station has a speaker 34. This is controlled by the processor 26 and outputs audio signals which can be heard by the user. A microphone 36 is provided to pick up the user's voice. The microphone signals are input to the processor 26 which converts the signals into a format suitable for output to the UMTS transceiver 24.
Referring back to
The information included in the identification can include any suitable information to allow the connection to be established. In preferred embodiments of the present invention, the identification includes a unique device address for the mobile station. This is effectively the Bluetooth address of the mobile station. This identity can be regarded as being similar to the telephone number of the mobile station. However, the UMTS telephone number will be different from the Bluetooth address. It is the Bluetooth number that is included in the identification information.
Reference will now be made to
The reader 18 would, in this case, be a bar code reader and would read the bar code 102. The bar code reader 18 would be able to read the unique address contained in the bar code 102. Using that information, the service access point 10 is able to establish a connection with the Bluetooth transceiver 28 of the mobile station.
Reference is now made to
This latter arrangement has the advantage in that the address of the mobile station can easily be changed without having to replace a bar code on the external cover of the mobile station.
Reference is made to
It should be appreciated that any alternative embodiment of the radio frequency tag can be used in alternative embodiments of the present invention. The radio frequency tag can be incorporated on an exterior surface of the mobile station. However, in preferred embodiments of the present invention, the radio frequency tag can be provided inside the casing as the reader will be able to interrogate the tag through the casing.
Reference is made to
In the embodiments of the invention described, the identification is provided on the mobile station. However, it is possible in certain embodiments of the present invention, that the reading apparatus be provided on the mobile station and the identification be provided at the service access point. In the latter case, communications would be established by the mobile station. In the embodiments described earlier, the communication between the Bluetooth transceiver of the mobile station and the service access point is initiated by the service access point.
The preferred embodiments of the present invention have been described as using a Bluetooth link. However, it should be appreciated that any other suitable radio frequency can be used. For example, infrared frequencies may be used. Preferred embodiments of the present invention use a short range connection between the mobile station and the service access point. However, this may not be required in certain embodiments of the present invention.
Embodiments of the present invention have a number of different applications. In one embodiment, the mobile station is used to make a transaction with and effectively acts as a credit card, a debit card or an electronic purse. Credit card information for money transfer is done using the Bluetooth connection link which is established between the service access point and the mobile station.
Embodiments of the present invention can for example be used at ticket gates. The mobile station includes a ticket to go to a film, concert, sports match or the like. The Bluetooth connection is established between the mobile station and the ticket gate using the identification information. The confirmation of the ticket details are then provided to the ticket gate from the mobile station via the Bluetooth link.
Embodiments of the invention can be used to obtain information from an information station. The ink is established and the information is exchanged using the Bluetooth connection. For example, the user can obtain train times etc from the information kiosk.
In an alternative embodiment of the present invention, the mobile station can be used to communicate with an automatic teller machine ATM to complete financial operations such as the loading of cash to an electronic purse, the withdrawal of cash or the like. The secure communication link between the station and the ATM is established with the ATM reading the address of the mobile station from its bar code or the like.
In some embodiments of the present invention, the mobile station may be arranged to act sole as a credit card or the like. In that case the UMTS circuitry can be omitted. The mobile station may thus include only the Bluetooth related circuitry. The display, keypad, speaker and/or microphone may therefore be omitted.
The described embodiments of the present invention have described a technique for establishing a connection between a service access point and a mobile station, It should be appreciated that embodiments of the present invention may be used to provide communication between any two or more communication devices. For example, embodiments of the present invention can be used to establish a connection between two or more mobile stations.
In the preferred embodiments of the present invention, the mobile station may be replaced by any suitable communication device. It should be appreciated that in some embodiments of the invention, the communication capabilities of the communication device and/or the service access point may be very limited. In alternative embodiments of the present invention, the communication capabilities of the communication device and/or the service access point may be more extensive.
