Description
PAGING SYSTEM
The invention relates to a method and system for transmitting and receiving paging messages.
Paging devices (pagers) are wireless telecommunications devices that receive and display numeric or text messages. One-way paging devices can only receive messages, while response paging devices and two-way paging devices can also acknowledge, reply to, and originate messages using an internal transmitter. Response pagers are generally able to show alphanumeric characters forming a message on a display and have a transmitter to acknowledge receipt of a message. A two-way pager is a type of response pager that has a built-in keyboard, enabling a mobile user to prepare alphanumeric replies to the received messages or the originate messages. Paging devices may operate as part of a paging system which includes one or more fixed transmitters (or in the case of response pagers and two-way pagers, one or more base stations comprising both transmitters and receivers), as well as a number of paging devices that can be carried by the mobile users.
Different categories of paging systems exist. On-site paging systems are used in buildings and are used to provide dedicated paging facilities, for instance private paging facility in a hospital. Hospitals commonly use on-site paging for communication with staff. Public Wide Area paging offers similar features as on-site paging, but provides radio coverage across a large geographical area using multiple transmitters.
In many applications the coverage both inside and outside building is important. In order to improve signal quality inside buildings repeater equipment may be installed in the buildings in the event that services would not be available in certain areas of the building. This is important, for instance, in hospital settings where emergency staff must be able to reliably receive pages in order to respond to patient needs. However, the instalment of repeater equipment is expensive and makes the paging system complex.
It is an object of the present invention to provide a system and method for transmitting and receiving paging messages wherein the above-identified and/or other disadvantages of the prior art have been reduced or removed.
It is another object of the present invention to provide a system and method for transmitting and receiving paging messages wherein a good overall coverage both inside and outside buildings is possible.
At least one of these objects is achieved in a paging system as defined in the preamble, the system comprising: - a mobile communication device configured to be carried by a user, the mobile communication device further being configured to establish a long-range wireless connection with a remote paging server and a short range wireless connection with a portable electronic paging device; - a portable electronic paging device configured to be carried by the user and to establish a short-range wireless connection with the mobile communication device for sending and receiving messages between the paging device and the paging server via the mobile communication device, the paging device comprising a display unit for displaying one or more messages received by the paging device.
The paging device may avail himself of technology already available in current mobile communication devices, thereby increasing the versatility of the device.
In an embodiment of the invention the system comprises a position determiner configured to determine position data representative of the actual position of the paging device and/or communication device. The paging device and/or the mobile communication device is further configured to transmit the position data to the paging server. The paging server aware of the actual indoor and/or outdoor positions of the users may make the messages transmitted to the individual paging devices dependent on the position of the user. For instance in case of an emergency in a specific part of a building, only the users that are positioned in this part of the building receive an alert message.
In other embodiments (wherein Location Based Services (LBS) are provided), the paging server sends an alert message as a broadcast to a all paging devices. The alert message contains an indication of the geographical position or area relevant for the alert message, for instance an indication of the room wherein medical staff needs to provide assistance. The alert message is received by the mobile communication device and transmitted to the paging device. The indication is received by the receiver of the paging device and provided to its controller. Based on the geographical information from the position determiner (for instance, the proximity relative to a preset number of neighbouring beacons and/or the proximity relative to one or more beacons in the recent past) and the received indication the controller may determine whether the paging device (and therefore the user) is sufficiently close to the location indicated and/or was recently close to the location indicated. When this is the case, the controller generates an alarm signal, for instance a message to be displayed on the display unit. On the contrary, when the paging device is too far away from the indicated position or outside the indicated area and/or when the paging device was too long ago near the indicated position or inside the indicated area, the controller decides not to generate the alarm signal.
In other embodiments the alert message is handled by the mobile communication device rather than by the paging device. The mobile communication device determines whether the mobile communication device (and therefore also the paging device) is sufficiently close to the location indicated in the alert message. When this is the case, the mobile communication device transmits the alert message to the paging device which generates an alarm to be displayed on the display unit. When this not the case, for instance because the mobile communication device is too far away from the indicated position or outside the indicated area and/or the mobile communication has not been near the indicated position in the recent past, the mobile communication device does not transmit the alert message to the paging device.
Mainly for outdoor situations use can be made of a GPS receiver already arranged in the mobile communication device. Alternatively or additionally use can be made of Cell-ID Wifi, NFC, or Bluetooth as position determiner. For indoor situations or situations wherein in increased accuracy is needed, the position determiner may comprise a plurality of electronic location beacons arranged at different positions and configured to provide respective beacon signals. The position determiner comprises a location beacon receiver arranged in the paging device. The location beacon receiver receives beacon signals from the individual electronic beacons. Based on the received beacon signal the (controller of) the paging device may determine its position relative to the beacons. In further embodiments the system comprises both a GPS (or similar) receiver in the mobile communication device and a location beacon receiver in the paging device so as to provide accurate positioning both in indoor en outdoor situations.
Preferably the display unit of the paging device is an electropheretic display. This type of display has a relatively low battery consumption. The device consumes energy only when changes in the displayed information occur. This allows information, such as information about the identity of the user, to be displayed permanently (so that the paging device may also be used as an identification device) while energy consumption of the paging device remains very low.
When the paging device is used as identification device or badge, for instance for identifying law enforcement personnel, medical staff, etc., at least one identification sign representative of the identity of the user carrying the paging device may be displayed on the display unit. The identification sign may comprises a graphic representation of the user. For instance, the identification sign may include a photograph of the user, possibly in combination with the user’s name and his professional duties. Alternatively or additionally, the identification sign may comprise a graphical code, for instance a barcode or QR-code, into which further information about de user may have been coded. The code can be read by a third party, for instance by the barcode or QR-code scanner of another member of the medical staff, or by the user himself.
In some embodiments of the present invention the paging device is designed to resemble an identification badge. The additional paging functions and/or alarm functions remain invisible or at least unnoticeable to the bystander.
In an embodiment of the invention the portable electronic paging device comprises: - a housing provided with a display unit; - a controller for controlling one or more functions of the paging device, preferably for starting or ending one or more functions of the paging device; and - an accelerometer for providing a sensor signal representative of the acceleration of the housing in at least one direction, preferably in three orthogonal directions; wherein the controller is configured to control one or more of functions depending on the received sensor signal.
For instance, a user may tape twice (or more) on the housing of the paging device. When the tapping is sensed by the accelerometer and the sensor signal is sent to the controller, the controller may start a specific function, for instance an alarm function or a reset function.
In an embodiment of the invention, the controller is configured to determine a motion type from a number of prestored motion types from the sensor signal received from the accelerometer and to select a function from a number of prestored functions based on the determined motion type.
For instance, the controller may control an alarm function of the paging device (wherein the paging device sends an alarm message to the paging server and/or has the paging device generate audible and/or visible alarms) when the sensor signal is representative of a “man down situation”. The sensor signal may indicate that the paging device does not extend in a vertical orientation while no movement of the paging device may be detected during a certain time interval. When a “man down situation” is detected, the controller generates a “man down” function, involving, for instance, the generation of an alarm signal and the transmittal of the alarm signal to the paging server.
Furthermore the portable electronic paging device may comprise: - an elongated, preferably rectangular, housing provided with an elongated display unit arranged parallel to the longitudinal direction of the housing; - a controller for controlling the display of messages on the display unit; - an orientation sensor for sensing the orientation of the housing; wherein the controller is configured to avoid displaying of messages on the display device when the housing is in a first orientation wherein the housing extends in a generally vertical direction and to allow displaying messages on the display device when the housing is in a second orientation wherein the housing has been tilted upward across at least 70 degrees, e.g. after getting an audible and/or visual alert that a new message came in. The orientation sensor may comprise the earlier mentioned accelerometer. However, the use of other types of orientation sensors are conceivable as well.
For most of the time the paging device is in the first (vertical) orientation and primarily functions as an identification means. When the paging device receives a paging message, the user is alerted by an audio and/or visual signal that the message has arrived. However, for privacy reasons the message is not shown on the display. Showing the message on the display would mean that bystanders could read the message. Once the user has tilted the housing of the paging device to a sufficient extent (i.e. over more than 70 degrees, preferably more than 90 degrees or 120 degrees), the controller has the message displayed on the display unit so that the message may be read by the user.
In a further embodiment the controller is configured to show a message on the display unit in a first display mode wherein the message is depicted extending in the longitudinal direction of the display unit or in a second display mode wherein the message is depicted extending in the transversal direction of the display unit. The controller may be configured to select a display mode depending on the orientation sensed by the orientation sensor.
As mentioned above the paging device may be designed to resemble an identification badge wherein the paging and/or alarm functions remain invisible or at least unnoticeable to the bystander. For this reason the paging device may further comprise: - a housing defining a front face, back face, upper and lower faces and a left and right side face; - at least two control buttons arranged at either side face; wherein the side faces are shaped such that the buttons remain essentially hidden behind the front face when observed from the front.
Persons in the neighbourhood of the user are not likely to notice the control buttons of the paging device so that they assume the paging device is an identification device or identification badge only.
For instance, the side faces of the housing are shaped so that each of them extends at an angle less than ninety degrees with respect to the front face. The side faces extend inwardly in an oblique manner so that the buttons are at least partly out of sight. Additionally or alternatively, the control buttons are recessed into the side faces of the housing so as to make them less visible to third persons in the neighbourhood of the user.
The controller may be configured to generate alarm messages, for instance in case the user is in danger. The alarm message may be triggered by the user depressing one of the buttons of the paging device. Flowever, in a further embodiment of the invention the paging device comprises two control buttons connected to a controller, the controller being configured to generate an alarm message when both control buttons are depressed simultaneously and for at least a predetermined time interval. These control buttons may be invisible to the bystanders and an alarm could be generated by the user without the bystanders noticing. The same buttons may be formed by a first and second button. The first and second button may be used to allow the user to react to messages received from the pager server. For instance, a first reply message (e.g. acknowledge) is sent from the pager device when the first button is depressed and a second reply message (e.g. reject) when the second button is depressed.
In a further embodiment the controller is configured to determine whether the distance between the mobile communication device and the paging device exceeds a predetermined threshold and to generate an alarm when the distance is larger than the predetermined threshold. The alarm may be an alarm signal generated by the controller and sent to the display unit for displaying an alarm message, an alarm signal to a loudspeaker for providing an audible alarm sound and/or an alarm signal to a light emitting unit for providing a visible alarm. In this manner the paging device alarms the user when the link between the paging device and the mobile communication device is lost.
Further advantages, features and details of the present invention will be elucidated on the basis of the following description of some embodiments thereof. Reference is made in the following description to the figures, in which:
Figure 1 shows a schematic overview of a paging system according to an embodiment of the present invention;
Figures 2A, 2B and 2C show a front view, back view and top view of an embodiment of a paging device in the paging system of figure 1; and
Figure 3 shows a more detailed schematic view of the front face of the embodiment of the paging device of figure 2.
Figure 1 shows an example embodiment of a paging system 1 to be used in a building (B). The figure shows a user (U), for instance a member of the medical staff of a hospital, staff of a mental home or a prison, etc., wearing a cell phone or mobile phone 5, more specifically a smart phone, that is configured to communicate with a wireless wide area communication network, for instance a cellular telephone network 4 (for instance, GSM, 3G, 4G, or similar network). To this end the smart phone comprises a first transceiver 6 for receiving and/or transmitting wireless signals to and from a number of land-based base stations, such as cellular radio towers 7. The wide area communication network enables communication inside and outside the building.
Similarly, the smart phone 5 comprises a second transceiver 8 configured to communicate with a wireless local area (communication) network 18, for instance a WiFi-network. The wireless local area network is comprised of one or more base stations (routers/gateways) 9 arranged in the building and providing for a good coverage in the building and at close range outside the building.
The smart telephone 5 comprises a third receiver 10 as well. The third transceiver 10 is configured to provide a short-range communication network 19 between the smart phone 5 and peripheral equipment, for instance a paging device 12. The short-range communication network may be a Bluethooth-network or any other suitable network proving two-way communication between the smart phone 5 and the paging device 12 so that the paging device 12 can function as the front-end of the smart phone 5.
The base stations 7 of the telephone network 4 and the base stations 9 of the wireless local area network 18 are connected through a wired network, for instance the internet, to a server 13 operating the paging system 1.
In the embodiment of figure 1, the paging device constitutes an identification badge 20 that is configured to identify the wearer of the device (i.e. the user (U)) and to provide the wearer, at the same time, with paging and/or alarming facilities. The badge 20 is usually worn by the user in a vertical orientation, as will be explained later, for instance by clipping the badge to a breast pocket. Figures 2 and 3 show an example embodiment of a paging device 12 according to the invention. The paging device comprises housing 15 of a generally elongated and rectangular shape. Inside the housing a transceiver 16 is positioned to enable the paging device 12 to communicate with the smart phone 12 using the short-range wireless communication network 19. In an opening of the housing a light emitting unit, for instance comprising one or more warning lights 42, for instance colour LED’s, has been arranged. In another opening, more specifically in an opening in the front face 25 of the housing 15, a display unit 31 is mounted. The display unit may comprise an LCD display. In example embodiments of the present invention, however, the display unit comprises an electropheretic display, herein also referred to as an electronic paper display (EPD) device or electronic ink paper display. One of the advantages of an EPD device is its low energy consumption. The warning lights 42, display unit 31 and transceiver 16 are connected to an electronic controller 41 which in turn is connected to a power supply formed by one or more rechargeable batteries 43.The rechargeable batteries can be charged by placing the housing of the paging device in a cradle 23 and/or by charging the batteries wirelessly (inductive charging).
As a result of the relatively low energy consumption of the EPD type of display, in embodiments of the invention, the EPD device is essentially permanently in an operational (i.e. visible) mode. This means that information, such as identification signs that are representative of the identity of the user, may be shown permanently on the display. When the information is displayed permanently or at least during prolonged time intervals. The paging device 12 may therefore function as an identification means or, in further embodiments, as a personal security communication device.
In figure 3, the display unit 31 in an embodiment of the invention is shown. The display 32 of the display unit 31 depicts in a first part 33 of the display screen an identification sign 34comprising a graphical representation, for instance -and not limited to- a photograph, of the user. In other embodiments, in a different part 35 of the display screen, the identification sign comprises the user’s name and profession as well. Alternatively or in additionally, an identification sign may be depicted in a third part 37 of the display screen. In this part of the display unit a code representation, for instance a QR-code 38 of the user is presented (in hospitals, sometimes codes must be scanned to ensure proper treatment, by combining a scan of the QR code of the badge of the professional, a scan of a patient’s badge, and a scan of a medicament code). In embodiments of the invention information is displayed permanently on at least one of the above described parts 33,35,37 of the display screen. In other embodiments the information is only displayed as a result of user action, for instance when the user operates one or more of the operating buttons and/or when the housing is tilted to face the eyes of the user.
Another aspect of the present disclosure relates to the conditions at which a message is shown or is avoided from being shown on the display device. For instance, for privacy reasons, the message may only be shown on the display unit when the housing, while still hanging from a lanyard or from the breast pocket, is tilted from the vertical orientation to a horizontal orientation. This is a movement made by the user by taking the housing and tilting it to look onto the display unit. In this orientation only the user can read the display, and any third party (bystander) in front of the user cannot read along.
In order to maintain the message private, in the housing 15 of the paging device 12 an orientation sensor 40 may be provided. For instance, a two or more accelerometers sensing the acceleration in two or three orthogonal directions may be used to have the controller 41 determine the actual position or orientation of the housing 15 of the paging device 12. The controller 41 may control the display unit 31 based on the sensor signals received from the orientation sensor 40.
As mentioned earlier, the paging device 12 is normally carried by the user in a substantially upright orientation, more specifically a vertical orientation, for instance clipped to the breast pocket of the user. In the upright, vertical orientation the display unit 41 may display one or more identification signs of the user, such as a photograph of the user’s face, his or her name and profession and a scannable QR-code. The paging device 12 now functions primarily as identification badge for proper identification of the user. No messages or other private information is shown on the display unit 31.
Once a message is received through the smart phone 5 linked to the paging device 5, a warning signal is provided to the user, such as one or more LEDs 42 at the top of the housing flashing in a particular colour and/or by a beep signal generated by a loudspeaker (not shown). In order for the user to see the message on the display unit, the housing should first by tilted by the user to bring the housing in another (second) orientation. Once the controller 41 detects a sufficient tilting of the housing based on the signal the controller receives from the orientation sensor 40, more specifically once the controller 41 has detected that the housing has been tilted upwards across an angle of 90 degrees or more so that the display unit 31 faces the eyes of the user, the controller allows the display unit 31 to display the message received from the smart phone. Similarly, when the controller 41 detects that the housing of the paging device is tilted back to the vertical orientation, it controls the display unit 31 to remove the message from the screen so that is not visible anymore to any bystander.
The message may be shown on the display unit in any orientation. In embodiments of the invention the controller 41 is configured to show the message on the display unit 31 in a first display mode wherein the message is depicted extending in the longitudinal direction of the display unit or in a second display mode wherein the message is depicted extending in the transversal direction of the display unit. The controller may be programmed to determine the orientation most suitable for the user the read the message, depending on the actual orientation of the housing sensed by the orientation sensor 40. For instance, the controller 41 may releases a message on the display to display the message in the longitudinal direction of the display, from left to right so that the user may easily read the displayed message.
Referring to figure 3, the housing 15 of the paging device 12 comprises a front face 25, back wall 26, left-hand side wall 27, right-hand side wall 28, an upper wall 29 and a lower wall 29. In the front face the display 32 of the display unit 31 is arranged, while in both side walls 27 and 28 operating buttons 45,46 are arranged, preferably at opposite positions. The buttons may be used to operate the controller 41 controlling the electronic parts of the paging device. For instance, the left-hand button 45 (in the colour green) may be used to accept a request from an incoming message, while the right-hand button 46 (in the colour red) may be used to reject the request. The controller may generate a reply message to be sent back to the server 13 depending on which of the two buttons 45,46 is depressed by the user. When both buttons are actuated simultaneously for more than a predetermined time interval, for instance by the user depressing the buttons by pinching the side-walls between thumb and index/middle/ring/little finger, the controller determines that an alarm situation has occurred. The controller transmits an alarm message to the server 13 via the smart phone 5. Upon receipt of the alarm message, appropriate action can be taken, for instance by an operator calling the user on his smart phone or alerting emergency services.
In other applications the controller checks whether a control message (LinkGuarding message) has been received. When such message has not been received by the paging device within a preset time interval, the controller determines that some kind of error has occurred and generates an alarm signal. Similarly, when a mobile communication device transmits a message to the paging device and does not receive reply back from the paging device within a preset time interval, the communication device raises the alarm. Therefore the communication link between the paging device and mobile communication device is monitored. Similarly, the communication between the mobile communication device and the paging server can be monitored and an alarm may be generated when the communication is lost.
In some applications the paging device may be used as an identification device. In these applications it might be helpful to give third parties in the neighbourhood of the user the impression that the paging device is merely an identification badge and that the badge cannot be used as a personal safety device. In embodiments of the invention the side faces or walls of the housing are shaped such that the buttons 45,46 remain essentially hidden behind the front face 25 of the housing, observed from the front. In this manner the buttons 45,46 (which may be used to raise an alarm) may not me noticed by other people around the user. In a specific embodiment each of the side walls 27,28 of the housing 15 extends inward at an angle (a) less than ninety degrees with respect to the front face. Alternatively or additionally, the control buttons 45,46 might be at least partially recessed into the side walls 27,28 of the housing 15. Standing in front of the user, the other person cannot see or hardly see the buttons 45,46 on the housing or the buttons so that the other person is basically unaware of their presence.
In further embodiments of the invention the paging system 1 comprises a position determiner configured to determine position data representative of the actual position of the paging device 12, the smart phone 5 or both the paging device and the smart phone. In a first set of embodiments uses is made of an existing satellite navigation system, such as the Global Positioning System (GPS), Galileo or similar system, to determine the position of the smart phone. Referring to figure 1, in an exemplary embodiment the smart phone 5 comprises a GPS receiver (not shown) to receive signals from one or more GPS satellites 51. The controller of the mobile phone is able to determine the actual geographical position of the smart phone 5 and therefore the user (U) based on the information received from the satellites. The smart phone 5 now may transmit position data representative of the actual geographical position to the paging server 13.
The satellite navigation system works especially well in outdoor situations. Indoor (i.e. inside a building) the positioning system may not function as well as outdoor. Furthermore, in indoor situations the accuracy of the geographical position determined sometimes needs to be much higher. For instance, in a hospital it would be helpful if the paging server 13 is aware of the current position of the medical staff in terms of which specific room the staff member is located. In these situations inside the building (and/or outside the building) a plurality of electronic location beacons 52 are positioned at different positions. The beacons 52 are configured to wirelessly transmit respective beacon signals to the paging device. The beacon signals may be received by a suitable beacon signal receiver 53 arranged in the housing 15 of the paging device. The controller 41 of the paging device is connected to the beacon signal receiver 53 and may determine an indication of the actual geographical position based on the beacon signals received by the beacon signal receiver 53. For instance, the controller may determine the proximity of the paging device with respect to a preset number of beacons (wherein the present number is one or more), wherein each beacon has a unique identifier. The controller then transmits position data representative of the actual proximity of the paging device (for instance the unique identifier(s) of the beacon(s) positioned closest to the paging device and/or the signal strength of signals received by the paging device) to the smart phone 5 and the smart phone 5 relays the position data to the paging server 13.
Based on the received information the paging server may determine the position of the user. In the example, the paging server determines the position based on the received identifier(s) and prestored information about the positions about each of the beacons.
Controller 41 may be configured to determine periodically whether the distance between the mobile communication device and the paging device exceeds a predetermined threshold. For example, the paging device may determine the time interval between sending a message to the mobile communication device and receiving a reply signal from the mobile communication device. The distance between the paging device and the mobile communication device can be determined from the time interval. In another example, the controller detects whether the mobile communication device is outside the receiving range or transmitting range of both devices. When the distance between the paging device and mobile communication device becomes too large (or when the link between the paging device and mobile communication device is lost for another reason), the controller may generate the alarm signal to inform the user. In still other embodiments the controller 41 is configured to determine whether the link between the paging device/mobile device and paging server works properly (also known as “link guarding”). When the link is lost, the paging device, mobile device and/or paging server do not respond to received message within a preset time interval. When a reply message has not been received in this time interval, the controller assumes that the link is lost and raises an alarm.
When an alarm signal is generated, the controller of the paging device may send information about the identity (for instance, a beacon ID) of one or more of the beacons the paging device has passed in a recent time interval. For instance, the controller may send information about the five beacons that the paging device has passed, preferably not only information about the identity of the beacons but also information about the order in which the beacons have been passed). Based on the information received, the paging server may determine the trajectory the paging device (i.e. the user) has recently followed, Based on the trajectory information, possibly in combination with a map of the building and information about the positions of the beacons in the building, the paging server may determine the actual position of the user. The determination of the location may be improved even further when time information (for instance, a time stamp) is transmitted together with the information about the identity of the beacon.
In embodiments of the invention, the paging device comprises a 3D accelerometer for providing a sensor signal representative of the acceleration of the housing in three orthogonal directions. The sensor signal is received by the controller. The controller may be configured to determine from the sensor signal a motion type from a number of motion types prestored on the paging device. For instance, when the user taps twice on the housing, the resulting sensor signal is interpreted by the controller as an motion of the motion type “tapping twice”. When this motion type has been determined, the controller starts a function associated with this motion type. For instance, the controller may initiate an alarm function (wherein an association between the motion type “tapping twice” and the “alarm function” has been prestored on a storage medium on the paging device. Another example of a motion type to be detected by the controller is the “fast move” motion type. When a person is running, the controller may detect the motion type “fast move” and start the “fast move” function. This function may involve, for instance, an alarm function so that the paging server is provided with an alarm signal. Another example is the “raw use” motion type. When the user is not handling the paging device with sufficient care and the paging device undergoes very high accelerations, the controller may detect a “raw use” motion from the plurality of different motion types stored on the paging device. The detection triggers a “raw use function” which may involve the storage of warning data in the storage medium. The warning data may be read by maintenance personnel. A further example is the “nurse shake” motion type. As soon as a nurse holding the paging device in her hand moves the paging device in a specific manner, generally referred to as the “nurse shake”, the controller may determine this motion type from the plurality of stored motion types and trigger a timer function on the paging device (for instance, generating a beep after 15 or 30 seconds to help the nurse getting a patient’s heart rate). A still further example is the “man down” motion type discussed earlier.
