The present invention relates to a method and a device for entering and forming an electronic message having a geographical display condition. The present invention also relates to a method and a device for forwarding such a message. Finally, the present invention also relates to a method and a device for displaying such a message.
Electronic messages like SMS (Short Message Service), EMS (Enhanced Message Service), and MMS (Multimedia Message Service) may be sent from one electronic communication device to another. The device transmitting the message may be portable, such as a mobile telephone. Alternatively, the transmitting device is stationary, such as a computer having access to the same communication network as the device receiving the message. Similarly, the receiving device may be stationary or portable. The message may be announced in the receiving device by a notification that a message is received or may be downloaded from a remote service node of the communication network.
A problem with both received electronic messages and notification messages is that the message or the notification message may not be relevant at once when the message is received. To be able to determine whether the message is relevant, the user has to read the electronic message, e.g. by downloading the message from a server. For example, Peter realizes that he and his wife Sara have run out of a specific type of ice cream only available in grocery store G. Thus, Peter sends an SMS message to Sara asking her to buy the specific type of ice cream only if she passes grocery store G on her way home. Sara receives the message without any delay when she is driving the car. However, Sara will not pass grocery store G on her way home. To do so, she would have to take a detour. Thus, the message is not relevant for Sara, as Peter only asks her to buy the specific type of ice cream if she passes grocery store G. Furthermore, Sara had to read the message while driving, which could be dangerous depending on the traffic situation. Consequently, it would have been better, if Sara would not have received the SMS message at all.

Further objects, features, and advantages of the invention will appear from the following description of several embodiments of the invention, wherein various aspects of the invention will be described in more detail with reference to the accompanying drawings, in which:
a-4c are block diagrams of communication devices illustrating geographical display conditions according to the invention;
The present invention provides methods and devices for conditional displaying of an electronic message or electronic notification message announcing an electronic message when one or several display conditions associated with the message are fulfilled. The present invention provides the possibility to delay displaying the message until the electronic device, and thus the user, is located at a certain geographical position. With regard to an electronic message received in one electronic device from another, the receiving device has to be located at or within a certain distance from a specific geographical position when the message or a notification thereof is displayed.
An electronic message within the meaning of the present invention may be a message received from another communication device, and is thus an external message. The electronic message may be displayed directly at the device receiving the message. Alternatively, the electronic message according to the invention is an electronic notification or alert message notifying the user that an electronic message has been received at the device itself or is available at a service node of the communication network relaying the message. The message may be temporarily stored at the service node until it is downloaded to the addressed device. The electronic message may e.g. be an SMS (Short Message Service), an EMS (Enhanced Message Service), or an MMS (Multimedia Message Service) message.
The electronic message or the notification thereof according to the invention may be displayed visually on a display or by signal lamps or other equipment for visual signalizing to the user. The message may also be displayed audibly in by means of a loudspeaker. The message may be rendered by transmitting a prerecorded or synthesized message, which may form part of the received message. The message may also be displayed sensibly by a vibrator signal.
The portable communication device according to the invention is not limited to a portable communication device per se, but can be incorporated into semi-portable or semi-stationary devices. Such semi-stationary devices comprises electronic equipment mounted into a moveably device, e.g. electronic equipment mounted into a vehicle.
The mobile terminal 1 comprises a man-machine or user interface (UI) comprising, but not limited to, a keypad 10, a microphone 11, a loudspeaker 12 and a display 13. The user interface may be used for operating and interacting with the mobile terminal, such as fetching an announced electronic message, and reading/writing an electronic message.
The mobile terminal 1 may optionally comprise various communication means for communicating with other electronic equipment. A first antenna 14 is adapted for communication with e.g. a mobile telecommunication network 15 over a first wireless link 16. The telecommunication network 15 may e.g. be a GSM (General System for Mobile communication), a UMTS (Universal Mobile Telecommunications System), a PDC (Personal Digital Cellular system), a IS-136, a IS-95, a IMT-2000 (International Mobile Telecommunications 2000) or any other communication network utilizing any of the frequency division, time division or code division techniques.
A second antenna 17 is adapted for short-range supplementary communication with a local area network 18 or a peripheral electronic device over a second wireless link 19. The second wireless link 10 may e.g. be a Bluetooth® link.
A third antenna or reception means 20 is adapted to receive position and time data from several satellites 21 (only one is shown) or pseudolites 22 (only one is shown). With pseudolite is meant a position data transmitting means, which is located on the ground and which transmits data similar to position and time data transmitted from a satellite 21. The mobile terminal 1 is adapted to determine the geographical position of the mobile terminal 1 on the surface of the earth. To determine the position, data from several satellites 21 or pseudolites 22 have to be received. The position and time data received from several pseudolites 22 may be used similar to position and time data received from the satellites 21 to determine the geographical position of the mobile terminal 1. The pseudolites 22 may e.g. form a local network for position determination in places wherein signals from the satellites 21 may not reach the mobile terminal 1.
An accessory connector 23 is provided for connecting the mobile terminal 1 to various peripheral devices. A computer 24 having input means, such as a keyboard and a mouse, may be connected to the accessory connector 23 by means of a cable 25, such as a serial cable. Alternatively, the computer 24 is connected to the mobile terminal 1 by means of a wireless link, such as the second link 19. The mobile terminal 1 may be connected to a global information network, such as the Internet, e.g. through the computer 24 or the mobile telecommunication network 15. It is possible to write messages according to the invention by means of the computer, which message may be transmitted to the communication network 15 trough the mobile terminal 1. Alternatively, the message is transmitted through a connection to the global information network.
A position determination unit 31 is connected to the third antenna 20. The position determination unit 31 is adapted to determine the geographical position of the mobile terminal 1 on the earth based on received position data. One such system for determining the geographical position comprises a GPS (Global Positioning System) receiver, which may receive positioning and timing data from the satellites 21 orbiting the earth or from the pseudolites 22 positioned on the surface of the earth. Based on the received position and timing data, the position determination unit 31 will generate a very exact geographical position of the mobile terminal 1.
Alternatively, the position determination unit 31 uses another position determination system, such as a network based positioning system, which may be collocated or consolidated with the base stations of the mobile telecommunication network. The network based positioning system determines the geographical position of the mobile terminal 1 e.g. based on received signal measurements. The measurements may comprise angle of arrival, time difference and signal strength of received signals. Once the geographical position of the mobile terminal 1 is determined, it may be reported back to the terminal 1.
It is also possible to determine the position of the mobile terminal 1 in a GSM telecommunication system. The mobile terminal 1 receives timing data from three different base transceiver stations. Based on the arrival time of the data received from the base transceiver stations, the geographical position of the mobile terminal 1 may be determined. One such system is the E-OTD (Enhanced Observed Time Difference).
A hybrid approach is that the mobile terminal 1 collects measurement data from its environment that are reported back to the network, which in turn uses the data to determine the geographical position of the mobile terminal 1, which may be reported back.
The position determination unit 31 is connected to a controller or central processing unit (CPU) 32, which may be used to implement one or several units of the mobile terminal 1 by software readable instructions.
The controller 32 is connected to a memory 33, which may comprise one or several storing means for temporarily and permanent storage of data and software instructions, such as a random access memory and a read only memory, in which geographical data and message data may be stored. The controller 32 is adapted to repeatedly obtain the specific geographical position or area, possibly by interrogating the position determination unit 31, in which the mobile terminal 1 currently is located. The determination is made with a predetermined time interval, such as every 10th second or every 5th minute. The time interval may be default or user defined as desired. Alternatively, the time interval is adaptively set depending on the speed of the mobile terminal 1, which may be determined by the position determination unit 31. The controller 32 may form part of the position determination unit 31. Alternatively, the position determination unit 31 comprises a separate processor for determining the geographical area in which the mobile terminal 1 is currently located.
A message interface or unit 34 comprises means for forming a message and append one or several associated display condition thereto. Also, the message interface 34 appends a receiver address, such as a telephone number, to the message when it should be transmitted to a remote communication device. The message interface 34 may form part of the user interface and be accessible by means of user selectable menus presented in the display 13. In a first window the user may enter the message, whereas the display condition(s) may be entered in a second window appearing when the message is completed. Thus, the message comprises a message or data payload field, an address field, and a display condition field.
The position of the mobile terminal 1 may be determined at the service node 50. The mobile terminal 1 may report terminal data uniquely identifying the terminal within the communication network. Depending of which one or several base stations that receives the terminal data, the position of the mobile terminal 1 may be determined by a position determination unit 51. The service node also comprises a communication unit 52 comprising a receiver for receiving an electronic message from a first electronic communication device and a transmitter for forwarding said message. The message or a notification thereof is forwarded when a second electronic communication device to which the message is addressed fulfills at least a geographical display condition specified in the message, as will be explained below. A memory 53, such as the memory 33 of the mobile terminal 1 is provided for temporarily storing the message and geographical position data. A central processing unit 54 may administrate the relaying of the message. Therefore, the processing unit 54 may comprise a condition unit 55, which may determine whether the conditions associated with the message are fulfilled. If so the controller 54 may transmit the message or the notification thereof to the addressed communication device. The condition unit may also be provided as a stand-alone unit.
The message may be announced and downloaded even if all display conditions are not fulfilled. Thus, the receiving device will determine when to display the message.
A proximity function may indicate whether the mobile terminal 1 is in the proximity of another mobile terminal if the network operator has knowledge of where mobile terminals are currently located. If the message comprises a display condition corresponding to the case illustrated in
a-4c illustrate exemplary geographical display conditions that have to be fulfilled in order to display the electronic message or a notification thereof at the mobile terminal 1. In

c describes a situation similar to
It is also possible that the geographical display condition comprises information requiring that the transmitting device should be located within a certain geographical area or within a certain distance thereof when the message is displayed in the receiving device.
The geographical display condition may be combined with one or several other display conditions. A time display condition may specify that the message should be displayed within a certain due date or time limit. If the electronic device in which the message is to be displayed is not within or within a certain distance d1, d2, d3, d4 of the geographical area Y, Z or another device within the time limit, the message will never be displayed.
The geographical areas may e.g. be defined by the geographical co-ordinates of the outer boundaries thereof. The coordinates may e.g. be provided with a certain mutual distance, wherein each area comprises an array of discrete co-ordinate values stored in e.g. the memory 33. Once the geographical position of the mobile terminal is determined, the controller 32, or an internal processing unit of the position determination unit 31, may determine whether the current geographical position of the mobile terminal 1 is within the boundaries of any of the specified areas. If not, the mobile terminal 1 is determined being within an unspecified area.
A service provider may provide area co-ordinate data. The co-ordinate data may be downloaded from a communication network, such as the mobile telecommunication network 15. The user may e.g. download area co-ordinate data relating to e.g. all shopping malls within a specific. Alternatively, such co-ordinate data is automatically downloaded when the mobile terminal 1 enters a new city or area.
The geographical co-ordinates may also be input into the mobile terminal 1 by means of a reading device, such as a bar code reader. E.g. a grocery store advertising in a newspaper or magazine could provide a bar code comprising the position data of the geographical location. Such information may also be downloaded from a web site.
A software tool run on the computer 24 for creating the geographical areas may also be provided. The software tool may e.g. provide maps over different countries and cities all over the world. Certain geographical areas within the maps may be defined by drawing a boundary around an area, e.g. by means of the mouse. Once the boundary is provided, the software tool will automatically generate the geographical co-ordinates of the area specified by the boundary. When the area is generated it may be transferred to the mobile terminal 1. Any geographical position falling outside a specified area may be specified as belonging to the unspecified area.
