Description

Various exemplary embodiments relate to a method for operating a mobile radio device.

In order to meet the increasing security needs of the population, static monitoring and security measures are increasingly being set up. Such measures are rarely actively monitored; their data are only saved for later use. These can therefore act as a deterrent against third parties, but cannot take active countermeasures or call for help.

The increasing need for security is countered by an increasing need for privacy, so that conventional monitoring and security measures in many areas of life find little acceptance or are inadmissible. For this reason, static monitoring and security measures are usually only concentrated in public areas and are rarely used in other areas, such as private life, in toilets or changing rooms. These and other unguarded areas can therefore become popular targets for third parties.

Clearly, privacy and protection through monitoring and security measures are in competition.

According to various embodiments, the method described herein enables improved protection against acts of third parties (e.g. harassment or criminal acts) without having to restrict privacy. A mobile radio device is clearly provided by means of the method, which can be put on alert when required and implements a mechanism that allows reliable detection when help is required.

According to various embodiments, a method for operating a mobile radio device in accordance with a first mode and a second mode can include: determining information about a location of the mobile radio device by means of a first sensor of the mobile radio device; Detecting a touch of the mobile radio device by means of a second sensor of the mobile radio device, switching to the second mode if it was determined in the first mode that the touch meets a first predefined criterion, generating a message according to a wireless communication protocol, if determined in the second mode the touch was interrupted, the message including the indication and further indicating that the touch was interrupted; Switching to the first mode without generating the message if it has been determined in the second mode that the touch meets a second predefined criterion. The second predefined criterion can be met, for example, when the first predefined criterion is no longer met.

The alert can be clearly established in the second mode and an alarm can be triggered by means of the message if the user loses control of the mobile radio device and thus loses contact with it (e.g. consciously or unconsciously). Once the danger is over, the mobile device can be switched to the first mode, which deactivates the alert.

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which there is shown, for purposes of illustration, specific embodiments in which the invention may be practiced. In this regard, directional terminology such as "top", "bottom", "front", "back", "front", "back", "left", "right", etc. is used with reference to the orientation of the figure being described ( en) used. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It goes without saying that other embodiments can be used and structural or logical changes can be made without departing from the scope of protection of the present invention. It goes without saying that the features of the various exemplary embodiments described herein can be combined with one another, unless specifically stated otherwise. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

In the context of this description, the terms “connected”, “connected” and “coupled” are used to describe both a direct and an indirect connection (e.g. wired or wireless), a direct or indirect connection and a direct or indirect coupling. Several elements can be coupled to one another, for example by means of the connection, along an interaction chain, along which the interaction (e.g. a signal) that transmits information can be transmitted. For example, two elements that are coupled to one another can exchange information (e.g. data) with one another. Devices that are communicatively coupled to one another can, for example, have mutually authenticated one another, so that they recognize one another. In the figures, identical or similar elements are provided with identical reference symbols, as far as this is appropriate.

According to various embodiments, a mobile radio device can be a mobile telephone, e.g. a feature phone or a smartphone, but also a radio signal receiver, a tablet, a laptop, a smartwatch or a mixture of these device types.

According to various embodiments, each individual user of the mobile radio device can be provided to be able to decide for himself at any time when he would like to take measures to increase his security based on his individual sense of security. For example, he can record harassment or criminal acts by means of a real-time video recording (vividly unmasking) and / or be connected quickly, easily and precisely to the helper who is available within the shortest range by means of a hand movement. Furthermore, a number of additional functionalities can be or will be provided, which differ according to the application or which merge into one another. These can optionally be activated / deactivated and / or configured by the user (also referred to as a voting decision) and serve to increase the actual security and thus also the user's sense of security. A choice made can be stored, for example (e.g. by means of a database), e.g. locally on the mobile device and / or on a computer system that receives the message, e.g. for later reuse.

According to various embodiments, an IT infrastructure (also referred to as a system) can be provided, which enables fast, smooth, location-based communication between the mobile radio device (clearly the call for help sender) and a receiver device (clearly the call for help receiver).

Various steps and details of the method are described below. It can be understood that what has been described (e.g. individual steps of the method) can be implemented analogously using hardware (e.g. a hard-wired circuit) and / or software (e.g. code segments or an entire application). For example, an application (also referred to as a program) can be provided which has corresponding code segments (e.g. program code) and which can be or can be executed on a processor and / or by means of a circuit which has the processor. The processor (or the circuit) can be part of a mobile radio device or a computer system, for example. The computer system can, for example, have a large number of processors which are arranged centrally within a physically coherent network or are also connected to one another in a decentralized manner by means of a cellular network. In the same way, code segments or the application can be executed on the same processor or parts thereof can be distributed over several processors which communicate with one another by means of the cellular network.

The transmission of information (information transmission) can according to various Embodiments take place according to a communication protocol (KP). The transmission of information can comprise generating and / or transmitting a message which contains the information in accordance with the communication protocol. The communication protocol can clearly designate an agreement according to which the transfer of information between two or more parties takes place. In its simplest form, the communication protocol can be defined as a set of rules that define the syntax, semantics and synchronization of information transfer. The communication protocol (eg a network protocol) can have a protocol stack made up of layers, in which the rules are divided among the individual levels of the protocol stack. The configuration of the protocol stack or its layers can be described, for example, by means of a reference model, for example the OSI model, which assigns those services to each layer that it is supposed to provide. The transmission of information via Bluetooth can include generating and / or transmitting a message containing the information in accordance with a Bluetooth communication protocol. The Bluetooth communication protocol can optionally have a low-energy protocol stack (low-energy protocol stack), ie the information can be transmitted via low-energy Bluetooth. By analogy, this can also apply to a communication protocol of a different type.

1 illustrates a procedure 100 for operating a mobile radio device 102 according to various embodiments in a schematic flow diagram. The method can be clearly set up to trigger an alarm in the event of loss of contact 111 when the cellular device 102 in a standby mode 109 is.

The procedure 100 can in 101 have: Get an indication of a location 151 of the mobile device 102 by means of a first sensor 102a of the mobile device 102 (also called localize 101 designated). The specification (also referred to as location specification) can for example be the coordinates of the location according to a spatial coordinate system 131 , 133 , 135 exhibit. The spatial coordinate system 131 , 133 , 135 can be a two-dimensional or three-dimensional coordinate system. The coordinate system can, for example, span the globe (also referred to as a geographic coordinate system) and specify the coordinates in geographical latitude and longitude or an equivalent thereto (also referred to as geographic coordinates). In general, however, the coordinate system can be any coordinate system that enables a clear indication of the geostationary location, with corresponding reference points in order to describe positions, vectors, movements and the like.

The first sensor 102a (also as a localization sensor 102a can be set up, for example, to communicate with a space-based navigation system (for example, for determining position by means of satellites). The space-based navigation system can, for example, have or be formed from a global positioning system (GPS), a global navigation satellite system (GLONASS), a European global navigation satellite system (Galileo) or a Chinese global navigation satellite system (Beidou). The space-based navigation system can have several geostationary satellites, which periodically broadcast their current position and the exact time by means of a coded radio signal.

The location sensor 102a can alternatively or additionally be set up to communicate with another navigation system (more generally geolocation system), for example a ground-based navigation system (for example radio navigation system). The ground-based navigation system can for example localize 101 be set up within a building, for example by means of several radio beacons within the building. Each radio beacon (more generally: radio transmitter) can broadcast its identifier, its current position and / or the exact time by means of a radio signal periodically and / or on request. However, other radio transmitters can also be used as a reference point for localization 101 can be used if the location of the radio transmitter and / or the mobile radio device is based on their radio signal 102 can be determined. For example, the radio transmitter can be a Bluetooth transmitter or a cellular radio transmitter (eg a transmission tower).

The localization 101 can optionally be done using a database. For example, the database can have an assignment of the recorded radio signal (or information contained therein) to the location of the transmitter of the radio signal.

The location sensor 102a can be set up to detect the radio signal and, on the basis of this, its location (and thus that of the mobile radio device 102 ) or at least a location area (ie an estimate) in which its location is located. The location sensor 102a can for example according to ISO 19762-5 be set up. The location sensor 102a can be used as an alternative or in addition to localization 101 be set up by means of odometry.

The procedure 100 can in 103 have: detecting a touch 103b of the mobile device 102 by means of a (eg touch-sensitive) second sensor 102b (also as a touch sensor 102b designated) of the mobile device 102 . The touch sensor 102b For example, it can be part of a touch-sensitive screen, a physical switch, an emulated switch, a fingerprint sensor (or another biometric sensor), or at least one touch-sensitive surface. More generally speaking, the touch sensor can 102b set up the event of touch 103b of the mobile device 102 by a user 104 of the mobile device 102 (here also as a user 104 designated). For example, the physical switch can be operated or what is called a touch 103b is captured. The touch sensor 102b can for example have or be formed from a capacitive, optical, resistive or inductive sensor.

The procedure can be carried out in 105 have the mobile device 102 between a first mode 107 (also known as sleep mode) and a second mode 109 (also known as standby mode).

When in sleep mode 107 it was determined that the touch 103b If a first predefined criterion (also referred to as the arming criterion) is met, the switchover can 105 into standby mode 109 take place (also as arming 105 or escalation). When in standby mode 109 it was determined that the touch 103b If a second predefined criterion (also referred to as the defusing criterion) is met, the switchover can 105 into sleep mode 107 take place (also as disarming 105 designated).

That or each in the context of the touch 103b The described criterion (also referred to as the touch criterion, for example the disarming criterion, the arming criterion or a recording criterion) can be fulfilled, for example, when the contact 103b takes place according to a predefined touch pattern (for example a gesture), for example with a predefined spatial and / or temporal distribution and / or intensity. The touch criterion can clearly define in which way the touch 103b should be done so that the touch 103b is interpreted as an input and / or a response from the mobile device 102 triggers.

For example, the criteria can be met when the touch 103b along a predefined trajectory or between two predefined areas on the touch sensor 102b he follows. For example, the touch criterion can be fulfilled when a predefined input (eg code) or a touch sequence (ie a sequence) is recorded. The touch criterion can clearly be met if, for example, in a certain way via the touch-sensitive surface (eg the screen 102b) is deleted and / or typed or when a physical button is pressed according to a certain sequence (e.g. three times in a row, several times short and / or long, or the like).

When in standby mode 109 it was determined that the touch 103b has been interrupted (also known as contact interruption or loss of contact), however, a message can 106 according to a communication protocol (KP) from the mobile radio device 102 generated 111 and / or sent 111 be (also called alerting 111 designated). The message 106 can have the location information (also referred to as geographic information) and also indicate directly or indirectly (for example, have information on this) that the touch 103b in the standby mode 109 interrupted (also known as alarm indication).

Alternatively or additionally, one or more than one additional message according to a communication protocol (KP) can be sent from the mobile radio device 102 generated 111 and / or sent 111 which has the location information and / or indicates that the mobile device 102 into standby mode 109 is or is switched over (also referred to as readiness indication), as will be described in more detail later.

The alarm information can, for example, have a complex word and / or an indicator that has only a few bits (e.g. one or two bits), e.g. a bit switch, as will be described in more detail later.

A KP set up for wireless communication (also referred to as wireless KP) can, for example, be in harmony with a cellular mobile radio network with which the mobile radio device 102 is connected, e.g. a GSM network, GPRS network, UMTS network and / or LTE network. The message 106 can for example be a voice message or a text message such as a short message (eg SMS), an instant message (eg instant message) or another text message according to a (eg proprietary) message protocol.

The wireless KP can, for example, define details of a network layer, data link layer and / or physical layer (according to the OSI model). The message can for example be on an overlying layer, e.g. the session layer or application layer, transmitted, sent and / or received.

The disarming 105 can for example be done without the message being generated 111 and / or sent 111 becomes.

2 illustrates a procedure 200 for operating a mobile radio device 102 according to various embodiments in a schematic flow diagram. The procedure 200 can clearly be set up to trigger an alarm after a timer has expired (also referred to as a time trigger or time switch) if the mobile radio device 102 is in a standby mode.

The procedure 200 can in 101 , 103 , 105 , 107 and 109 be set up as the procedure 100 with the difference that the message 106 generated 111 and / or sent 111 will when in the standby mode 109 instead of the interruption of contact it was determined that a predefined period of time 201 has elapsed (also known as timeout or timeout of the timer). The alarm indication can then accordingly indicate that in the standby mode 109 the period has passed. Counting down the predefined period 201 or determining that the period 201 has elapsed can be implemented, for example, by means of the time trigger, for example by means of a software-supported time trigger, which is, for example, from a clock of the mobile radio device 102 is controlled and / or reads a time provided by the operating system.

More generally speaking, it can alarm 111 done when in the standby mode 109 a predefined event is determined. The alarm indication can then accordingly indicate that the predefined event is in the standby mode 109 has occurred. The predefined event can generally represent that the user 104 is no longer in control or needs help. The predefined event can be, for example, the interruption of contact or the lapse of time.

The period 201 can for example by the user 104 be or become set by yourself, e.g. when in standby mode 109 is switched and / or already in the idle mode 107 . The input for setting the time period can be made, for example, by operating (eg touching) the mobile radio device 102 respectively.

The predefined event can, however, also have a connection with the mobile radio device 102 coupled (eg via radio) external device (also referred to as an external triggering device) is actuated, for example according to the arming criterion and / or another actuation pattern. The external triggering device can be, for example, a wireless switch (e.g. a Bluetooth switch), a music player, an activity monitoring device (e.g. health bracelet or health badge), a remote control, intelligent glasses or an intelligent watch (e.g. a smart watch). This external triggering device can optionally be the mobile radio device 102 for the transmission of the message 106 use. The communication between the cellular device 102 and the external triggering device can be done via Bluetooth, for example. For example, external control buttons of a smartphone, a smart watch or external triggers that can be integrated via Bluetooth or other means can be used to trigger the event.

3 illustrates a system 300 to carry out the procedure 100 or 200 according to various embodiments in a schematic communication diagram.

The system 300 can connect to a network 302 have (also known as a network connection), e.g. an Internet connection. Using the network 302 can the components of the system 300 to be communicatively coupled to one another, ie to be able to exchange information.

The network 302 can have several sub-networks that are interconnected. The network 302 For example, a local network can be differentiated according to range 302 (for example a Local Area Network (LAN), a Wireless LAN (WLAN), or a Personal Area Network (PAN) such as a wireless PAN (WPAN) such as a Bluetooth network) or a non-local network 302 (such as a Metropolitan Area Network (MAN), a Wide Area Network (WAN) or a Global Area Network (GAN)) or be formed from it. The network 302 For example, a radio network can be differentiated according to the type of transmission 302 (e.g. cellular network) or a wired network 302 have or be formed from it. The network 302 can also be a cellular radio network, for example 302 (e.g. a WLAN of the type IEEE 802.11 in ad-hoc mode, a Bluetooth network or another cellular cellular network 302 ) have or be formed from them.

In the following, reference is made to an Internet connection, ie the system 300 connect to the internet 302 (global network of computer networks) or is part of it. What has been described can, however, also apply analogously to other constellations or networks.

The system 300 can the mobile device 102 exhibit. The cellular device 102 can be set up wirelessly (ie by radio) with the network 302 to communicate 301 , e.g. according to the wireless KP. Thus the message 106 to the network 302 be transmitted, for example according to the wireless KP.

The system 300 can also have a computer system 304 have, for example a server, computer or the like. The computing system 304 can with the network 302 communicatively connected 303 be, e.g. according to a network KP. The message 106 can for example according to the wireless KP to the computer system 304 be addressed so that they can be accessed via the network 302 to the computer system 304 is transmitted.

The system 300 can also be a receiving device 306 have which with the network 302 communicatively connected 305 is. The receiving device 306 can for example be a mobile device, for example another mobile radio device, for example a pager, for example a laptop, or the like. Then the receiving device can 306 with the network 302 be connected according to the or another wireless KP. The receiving device 306 but can also be a stationary device, e.g. a television, a smart home device, or a permanently wired one 305 Computer or the like. Furthermore, the receiving device 306 with the network 302 connected according to the or another network KP 305 his. The system 300 can, for example, a variety of receiving devices 306 exhibit. Any receiving device 306 can optionally be used by the system 300 be or will be registered, for example by means of a database of the computer system 304 .

The message 106 can optionally provide information about the receiving device 306 have (also referred to as address information), e.g. an identifier of the recipient device 306 . The computing system 304 can then be set up to include the address information from the message 106 to extract and the message 106 or at least its content (e.g. as a new message 106 ) to the receiving device 306 to be transmitted according to the address details.

The receiving device 306 can be set up to provide the location data by means of the message 106 to determine and output this together with the alarm information 323 (also as an alarm 323 labeled), e.g. visually and / or acoustically. Alternatively or additionally, however, the computer system can also 304 be set up to extract the location data and the alarm information and the recipient device 306 a command (e.g. as a new message 106 ) to transmit which the receiving device 306 to sounding the alarm 323 caused. Sounding the alarm 323 may for example have to display a map that has a marking according to the location information. Optionally, the receiving device 306 be set up to determine navigation data, which is a route to the location of the recipient device 306 represent according to the location, and output them.

Optionally, the system 300 be set up a communication link between the receiving device 306 and the mobile device 102 to initiate, e.g. a voice connection. It can thus be achieved that a user of the receiving device 306 (also referred to as recipient or security provider) with the user 104 Can hold consultation.

Know the system 300 optionally several receiver devices 306 on, the computer can 304 be set up one of these receiver devices 306 select to which the message or command is transmitted (also known as select recipient). The recipient can select, for example, each of the recipient devices based on a respective location 306 , a respective availability of each of the receiving devices 306 , one from the user 104 defined preference and / or address information. For example, that receiving device 306 selected for the mobile device 102 closest to the one that has the greatest preference and / or that is marked available.

The cellular device 102 can have an application. The application can for example be a local application, for example on the mobile radio device 102 installed (e.g. embedded in the operating system in a non-volatile manner) and / or executed by it. Alternatively or additionally, the application can be a web application. The web application can, for example, be on the computer system 304 and only their user interface on a web browser of the mobile device 102 can be displayed (e.g. analogous to remote access).

The application can be set up with the computing system 304 to communicate (e.g. on the application layer), e.g. to transmit the message 106 and / or to retrieve information (eg an update) or data from the database.

The system 300 optionally has the external release device 322 on which, for example, with the mobile device 102 and / or the network 302 coupled 322k is. The system 300 optionally assigns one or more than one radio beacon 308 (also known as a beacon) that connects to the network 302 (e.g. wired) connected 307 is. The or each radio beacon 308 can for example be set up with the mobile radio device 102 to communicate wirelessly 309 , e.g. to the mobile device 102 a position and / or identifier of the radio beacon 308 to transmit and / or by means of the radio beacon 308 the message 106 to the network 302 to submit.

The message 106 can on its way through the network (e.g. until it is received at the computer system 304 and / or the receiving device 306 ) can optionally be transferred according to different KP. For example, the message 106 one after the other according to a Bluetooth KP, a TCP / IP KP (Transmission Control Protocol / Internet KP), and again a Bluetooth KP.

In the system 300 one or more than one component can be omitted, depending on how the process is carried out, e.g. the radio beacon (s) 308 , the computer system 304 and / or the triggering device 322 .

• • an information 412u (also referred to as environmental information) about a quality of the spatial environment of the mobile radio device 102 (e.g. a map, escape routes, etc.);
• • a hint 406 (also referred to as a touch indication) for a touch that would meet one or more than one touch criterion (eg a directional information, a symbol or a pre-drawn path);
• • an indication of which or that the application is running (e.g. the application name and / or an activity note); and or
• • Information about the expiry of the time trigger.

The reactive part 404 can for example at least the receiver device information 412e , the environment information 412u and / or the location information 412s exhibit. The interactive part 402 can, for example, at least the mode information and / or the touch message 412s exhibit. The touch notice 412s For example, may indicate one or more than one area of the touch sensor where the touch 103b should begin and / or end and / or along which the touch should be changed (eg a trajectory).

The detection information, the mode information and / or the touch indication can be or will be superimposed on one another, for example. For example, a virtual marker 412s (for example a controller position) are displayed, the color of which represents the mode information, the position of which represents the detection information and / or the one or more symbols 406 (for example an arrow), which represents the touch indication and / or the mode information. Other symbols can also be used 416 , 426 which represent the touch indication and / or the mode information.

The location information 412s may include, for example, the coordinates and / or a name of the location, such as the street name, city name, country name, etc. The recipient device information 412e and / or the location information 412s can for example with the environment information 412u be or become superimposed.

The interactive part 402 can for example in the lower quarter of the display device 112 of the mobile device 102 can be displayed, for example in the form of a slider 402s (also known as a slider), with the help of which the user 104 with the application 452 can interact, eg activate and / or control one or more than one functionality of the application.

Instead of the slider 402s can alternatively or additionally have one or more than one other physical control element 402s (e.g. a button on the mobile device 102 ) and / or virtual control element 402s (For example a navigation bar or a rotary knob) can be used, the actuation of which, for example, by means of the display device 112 of the mobile device 102 can be displayed as feedback. The application 452 can use the touch gestures of the user 104 evaluate the operating system of the mobile device 102 recorded and made available via its programming interfaces. Should the number of touch points that the operating system detects change or should the slide control change 402s operating fingers from the mobile device 102 removed so the application can 452 to react to that.

In the following, an operating element is used to simplify understanding 402s in the form of a slider 402s with a marker 412m Referenced. The same can also be done analogously for other shapes and / or configurations of the operating element 402s be valid.

The slider 402s can have a surface on which the marker 412m can be moved horizontally and / or vertically by means of touch gestures, as will be described in more detail later. The position of the marker on the far left (more generally a first marker position) corresponds, for example, to 0% of the slider. The position of the marker on the far right (more generally a second marker position) corresponds, for example, to 100% of the slider. The touch 103b of the slider 402s can be recorded and / or read out by the application and by positioning the marker (e.g. changing the marker position) at the point of contact 103b be reported back. The area between the first marker position (eg on the left edge of the area) and the current position of the marker can be highlighted in color to indicate the current mode 107 , 109 of the mobile device 102 to display.

The slider shows at different points on the surface 402s Symbols 406 , 416 , 426 (Icons) depending on the position of the marker 412m grayed out (not activated) and / or highlighted (activated). In addition, the application 452 react differently, depending on the position of the marker 412m is released. Will touch the slider 402s in the sleep mode 107 interrupted, the marker can, for example, jump to the first marker position. In combination, these contact and feedback patterns allow complex interaction of the user with just a single control element 104 with the mobile device 102 (e.g. its application 452 ), e.g. without the user 104 is overwhelmed in a stressful situation.

Communication between the application 452 (also known as an app) and the computer system 304 (e.g. servers) can for example over the Internet 302 respectively. As an alternative or in addition, additional communication paths can be or will be provided, as will be described in greater detail later, which are used, for example, when communication is via the Internet 302 is restricted (e.g. blocked). For example, depending on the programming interfaces provided by the operating system (for example iOS and / or Android), the alarm can be triggered 111 by means of an SMS and / or telephony, if communication via this is possible. Alternatively or additionally, the alarm can be triggered 111 via Bluetooth.

At least some of the symbols 416 , 426 can, for example, correspond to a position in which the marker is to be brought to a functionality of the application 452 to control (e.g. to start) and / or to meet a contact criterion. For example, it can bring the marker 412m to the second marker position 426 cause the alarming 111 he follows. For example, it can bring the marker 412m to a third marker position 416 between the first and second marker position (for example at about 50%) cause a third sensor (for example a camera, for example video camera) of the mobile radio device 102 is activated and / or audio data and / or image data are recorded by means of this (also referred to as recording the surroundings).

By touching the slider 402s (ie active control) can be the mobile device 102 between sleep mode 107 and the standby mode 109 switched 105 as explained in more detail below. The reactive part 404 can optionally be switched, depending on the mode or the respective functionality of the application 452 which the user 104 using the slider 402s drives.

5 illustrates a cellular device 102 in the sleep mode 107 in a schematic plan view 500 analogous to plan view 400 . The Sleep mode 107 can be the initial state in which the mobile device 102 is brought or will when the application 452 started and / or brought to the foreground. Without operating the slider 402s (e.g. moving the marker 412m to the right), the slider can 402s indicate that the cellular device 102 in the sleep mode 107 is. In sleep mode 107 can become the marker 412m for example, are in the first marker position. The slider 402s and / or the marker 412m For example, their appearance (eg color, shape and / or size) can be varied 412s, eg periodically (clearly “breathing”) to indicate that the application is being carried out (ie as an activity indicator). The slider 402s can optionally indicate that there is an opportunity to exit from sleep mode 107 to initiate that a video recording (for video evidence) is started, e.g. by placing the marker 412m to a third marker position 416 is moved and / or that the alarming 111 is carried out, e.g. in which the marker 412m the second marker position 426 is moved.

In the sleep mode 107 can include the location information (e.g. GPS coordinates, the street, the area and / or XY coordinates of the geodata of the mobile device 102 having) to the receiving device 306 be transmitted.

For locating 101 (Simplified as locating the mobile device 102 The programming interfaces provided by the operating system can primarily be used. In addition to localization via GPS, these also use the WiFi topology and other technologies to control the mobile device 102 localize as precisely as possible 101 to be able to. Optionally, signals from a Bluetooth radio beacon 308 near the cellular device 102 captured by this to the location of the cellular device 102 to determine. For example, the application 452 Data from own radio beacons 308 of the system 300 detect, which are arranged, for example, within a building to localize 101 to facilitate in buildings. The position of a radio beacon 308 can for example by means of a database of the computer system 304 be or will be stored or communicated by the radio beacon itself. The position of a radio beacon 308 can for example from the mobile device 102 (e.g. from the application 452 ) are determined on the basis of the database. The data obtained in this way can be combined with the data provided by the operating system, which makes it possible to determine the location of the mobile radio device 102 to be determined with higher accuracy. The or each radio beacon 308 thus facilitates localization 101 and / or can optionally provide an additional communication path. More generally speaking, it can localize 101 Use common location standards (e.g. subsequently integrated or updated).

On the second face of the display device 404 can be a card 412u displayed to the user 104 signals that he is connecting to the system 300 and / or the receiving device 306 (is clearly "on the radar" of the respective helper), for example if he has authorized this by voting. Alternatively or additionally, a radio beacon 308 signal (e.g. the mobile device 102 ) that the mobile device 102 in one of the system 300 monitored environment, e.g. even if its connection to the network 302 is restricted or interrupted (e.g. without an Internet connection). Alerting 111 can take place, for example, by means of secured areas (so-called security areas) and can thus for example also without a connection to the mobile radio device 102 to the network 302 as will be described in more detail later.

On the second face of the display device 404 can optionally be specified that the location information 412s to the receiving device 306 was transmitted and / or that the receiving device 306 is available. For example, the receiving device 306 be set up to identify themselves as available and / or not available via user input, for example in response to the receipt of the location information. In this way, the security provider can clearly understand where the user is 104 stops, and the user 104 can gain knowledge that its location is known to the security provider. This can be done by the user 104 convey a self-determined and calm feeling and thus prevent wrong decisions and / or stress.

6th illustrates a cellular device 102 in the standby mode 109 in a schematic plan view 600 analogous to plan view 400 . The marker 412m can be touched by the user 104 follow, ie its appearance (eg position, color and / or shape) can represent the detection information. This allows direct feedback to the user 104 occur that and / or how his touch was detected. For arming 105 of the mobile device 102 can the user 104 the marker 412m move by touching (ie active), e.g. to the right. So the marker can 412m be arranged next to the first marker position. In response to arming 105 can optionally receive feedback from the mobile radio device 102 will be given. For example, the marker 412m can be changed in its appearance (e.g. color) and / or the mobile device 102 can provide haptic feedback, for example by means of a vibration.

As long as the user 104 the touch contact in the standby mode 109 go to the slider 402s (e.g. its marker) cannot raise an alarm 111 respectively. In response to that in the standby mode 109 was recorded that the user 104 (e.g. his finger) the touch contact with the slider 402s loses (e.g. through internal or external influence), the alarm can be triggered 111 respectively. This mechanism makes it more difficult for a third party (eg an attacker), the user 104 the cellular device 102 to steal without breaking contact, or to disarm 105 to be carried out without the consent of the user 104 to have. For example, a third person would have to immediately and forcefully remove the user's finger 104 Hold on to the exact position to raise the alarm 111 to prevent. Then the user's finger would have to 104 be forcibly returned to the first marker position.

Optionally, the marker 412m automatically indicate that the alarming 111 has taken place, for example by moving it further in the direction of the second marker position 426 moved and / or changed in its appearance. The disarming 105 of the mobile device 102 can for example only be done by the marker 412m is returned by means of the touch in the direction of the first marker position (eg to the left).

More generally speaking, a first touch pattern (for example a swiping gesture to the right) can activate the arming 105 and an opposite (for example inverted) second contact pattern disarms 105 trigger. However, the second touch pattern need not necessarily be opposite to the first touch pattern. For example, deactivation can alternatively or additionally 105 only when entering an authentication code (ie that the second touch pattern represents the authentication code, among other things).

As long as the user's finger 104 in touch with the slider 402s remains, the mobile device can 102 in the standby mode 109 stay without the alarm 111 perform. Thus, the user can 104 be sure that he is in full control of his cellular device 102 remains as long as he is in touch with the same. If the touch contact is interrupted, this can be done by the user 104 to be wanted. Otherwise, if you lose contact with the slider 402s always automatically alerting 111 except if the cellular device 102 in sleep mode 107 is. To the cellular device 102 to defuse 105 (ie in sleep mode 107 to switch), it may be necessary, for example, that the user 104 the slider 402s moves completely to the left again without contacting the slider 402s to lose. Operating the slider 402s (e.g. moving the marker back and forth 412m) to focus 105 and disarm 105 of the mobile device 102 can optionally each with a short vibration from the mobile device 102 be acknowledged. The user 104 thus receives haptic feedback that the application 452 still responded.

7th illustrates a cellular device 102 in a schematic plan view 700 analogous to plan view 400 when the cellular device 102 in the standby mode 109 is. Optionally, the procedure 100 or 200 have that environment data, for example audio data and / or image data, are recorded, for example by means of the third sensor of the mobile radio device (also referred to as environment recording). The third sensor can have a camera and / or a microphone. The image data can include, for example, photo data and / or video data or be formed therefrom.

The environment recording can be done when in the standby mode 109 it has been determined that the touch meets a third predefined criterion (also referred to as the recording criterion). The recording criterion can be met, for example, when the marker is in the third marker position 416 and / or a camera symbol 416 of the slider 402s is pulled.

Instead of being permanently monitored, the user can 104 the voting decision to use the mobile device 102 to be able to guard themselves, are provided, for example by means of the video camera of the mobile radio device 102 . For self-protection, a potential attacker can be deterred while his actions are simultaneously recorded by recording the surroundings (e.g. video and / or audio recording). This can improve monitoring compared to static monitoring and security measures. This can prevent unguarded areas from becoming a popular target for third parties. The recordings of the audio and / or image data can optionally be used for post-criminal evidence preservation. To protect against misuse and forcible removal of the recorded evidence, the recordings can be stored locally and / or on the computer system, depending on network coverage 304 (e.g. external server) and stored there.

In the sleep mode 107 (e.g. if the application 452 is inactive or stopped in the background) the application cannot record the environment 452 occur (ie that no audio and / or video data is recorded). Depending on the operating system, the environment recording can only be performed with im Foreground of the running application 452 be possible and / or take place automatically as soon as the arming is activated 105 by the user 104 he follows. Once started, the recording of the surroundings can optionally also be continued when the mobile radio device 102 no longer with the user 104 is in contact, e.g. when the user 104 the slider 112m no longer touched.

Unless the application 452 from the user 104 has been started (e.g. in the foreground or visible in the background, e.g. as a daemon), the location of the mobile device can be 102 from the application 452 read out and / or periodically updated (clearly logged), for example similar to or based on a map navigation or map navigation application.

The recording of the environment can, for example, have to link the environment data (for example image and / or audio data) with the location information (for example geodata). For example, the environmental data can be georeferenced. The environmental data can be stored in the data memory of the mobile radio device 102 get saved. Alternatively or additionally, the environment data can be transmitted externally, for example in several data packets, according to the wireless KP, for example to one of the application 452 assigned cloud storage of the computer system 304 and stored there.

The external from the cellular device 102 stored environmental data can be given to the user 104 by means of the application 452 or made accessible in another way, e.g. for a fixed duration (also referred to as the accessibility period). The user 104 of the mobile device 102 For your own protection, you can choose not to be able to delete the stored video material (e.g. for the duration of accessibility) so as not to be blackmailed by third parties. The environmental data can be automatically deleted after a different, fixed period of time, e.g. from the computer system 304 . If the environmental data contain relevant data for criminal prosecution of the third party, the user can 104 the voting decision is provided, the material from the cloud storage of the computer system 304 within the accessibility period on the mobile device 102 and / or a cloud storage of the user 104 download and thus freely dispose of it. The metadata (eg length, resolution, etc.) of the environmental data and / or the location information can be stored anonymously, for example.

The wireless KP used can support the transmission of the location information and / or the environmental data of a few seconds by means of sequential data packets. This ensures that individual interruptions in the event of a poor communication connection or an intervention by a third party do not compromise the entire recording. The computing system 304 can only store a user ID (e.g. a one-to-one 64-character string) for the assignment of the data packets, which does not allow any conclusions to be drawn about the person of the user 104 allows. If communication is to take place with a public (e.g. state) emergency number (e.g. with the police), it may optionally be necessary that the cell phone number of the cell phone device 102 from the application 452 has been validated. More generally speaking, instead of the emergency number, another public (e.g. state) or private emergency contact can be used.

The computing system 304 can, however, be free of information on the mobile phone number of the mobile device 102 stay. Alternatively or additionally, the mobile phone number cannot be sent to the computer system together with the user ID 304 be transmitted. The user 104 may optionally include personal information from yourself using the application 452 provide, e.g. his name and his picture, in order to facilitate identification by the guarantor.

When the slider 402s by moving the marker 412m has exceeded a certain activation threshold to the right (for example in the middle of the slider 402s) , the environment recording can be started. The environment recording can be stopped as soon as the slider 402s was shifted to the left again below the activation threshold. The cellular device 102 meanwhile can be in standby mode all the time 109 stay even if the environment recording is stopped. To go back to sleep mode starting from the activated environment recording 107 To get there, it may be necessary, as described above, to use the marker 412m to move back to the first marker position without touching the marker 412m to lose. More generally speaking, the defusing criterion can be met if the marker 412m is brought to the first marker position.

In order to reduce the risk of interruption of the touch (i.e. the loss of touch) for sequential fulfillment of the arming criterion and the recording criterion, the respective criteria can be set up in such a way that they can be fulfilled by means of a continuation and / or non-opposing contact. The user 104 can thus record the marker based on the activated environment 412m Move even further to the right to set the alarm 111 trigger manually, or to the left move to stop environmental recording or to sleep 107 to switch. A release of the marker 412m when recording surroundings, this can alarm 111 trigger.

During the recording of the environment, the environment data can optionally be mapped (clearly "hashed") in sections by means of a (e.g. cryptographic) hash function and / or stored on a block chain (also known as blockchain), which ensures that these are clearly verified over time. The block chain can provide a continuously expandable list of data records, called “blocks”, which are linked to one another by means of a cryptographic process (eg by means of the hash function). The deletion of the environmental data can thus be done by the computer operator 304 difficult or impossible without leaving a trace. For example, a logic can be provided which is set up to generate environmental data including the associated position information and to save its image generated by means of the hash function on one of the block chains.

For everyone from the computer system 304 received data packet from the mobile device 102 a checksum can be calculated and combined with the user ID (e.g. a unique identification information for the user 104 ) for further data transfer to an external service provider who can provide auditable logging. This achieves that even the operator of the computer system 304 and / or application 452 cannot manipulate environmental data unnoticed and thus increases security. A block chain can be used for distributed logging, since a broader distribution of the data makes it more difficult for third parties to compromise. The computing system 304 can make log data available via a programming interface so that the environmental data can be saved by a non-governmental organization, for example.

8th illustrates a cellular device 102 in the standby mode 109 in a schematic plan view 800 analogous to plan view 400 when the alarming 111 he follows. Should be the user 104 are in a situation in which they need support, they can, as an alternative or in addition to recording their surroundings, manually raise the alarm 111 , ie clearly trigger an active call for help. Alerting 111 can for example be triggered by the marker 412m released or moved to the second marker position. The alarm can be optionally activated 111 if done by the cellular device 102 it was determined that the external trip device 322 has been actuated for a defined number of repetitions.

Alerting 111 may have the receiving device 306 to transmit the location information. The security provider can thus very specifically and quickly provide support (eg security) to the user 104 be informed without losing time for location or clarification of responsibilities. The user 104 the voting decision can optionally be provided to store additional personal data (such as a picture of yourself), which are sent to the recipient device together with the location information 306 be transmitted to the user 104 to enable a more targeted search on site.

Optionally, each receiving device 306 at least one geographical area of responsibility (clearly its useful range) can be assigned, e.g. based on its location (e.g. the geoposition). The area of responsibility can for example be represented by means of a geofence (also referred to as a geofence) (eg its contour). The area of responsibility and / or the geo fence can be determined, for example, by means of the computer system 304 respectively. A geo fence can be understood as a (eg virtual) border for a geographic (eg real) area. The geographic area can be spatially two- or three-dimensional. The geo-fence can be implemented based on a geolocation system by providing data that describe the position, orientation and / or shape of the virtual boundary in two- or three-dimensional form. The geo-fence can be determined for example by means of polygons using geo-coordinates. The area bounded by the geo-fence (also referred to as a geo-fenced area) can be, for example, the virtual equivalent of a real area of responsibility. The geo-fence and / or the geo-fenced area can be stored and / or defined, for example, using the GeoJSON format or another geomarking format.

The message 106 can then at least to the recipient device (s) 306 be transmitted to the area of responsibility in which the location of the mobile device 102 is / are assigned. The computing system 304 can be based on the means of the message 106 determine the corresponding area of responsibility, as well as the recipient device marked as available within the area of responsibility within the shortest possible range 306 determine and also send this to the mobile device 102 convey. Is at the location of the cellular device 102 no area of responsibility assigned, the emergency contact (e.g. the police) can optionally be alerted as a fallback level. For locating 101 of the mobile device 102 can generally use the Operating system of the mobile device 102 The coordinates provided are used (e.g. geoposition via GPS, radio barges and other positioning techniques). For locating 101 localization can be done inside buildings 101 additionally have a large number of radio boats submitted for this purpose 308 to be used, as will be described in more detail later.

The transition between different areas of responsibility can be made using the computer system 304 determined periodically and / or the user 104 are displayed. The user 104 can thus see at any time which security providers are available and responsible at his geoposition and can decide himself whether he would like to request their help.

Everyone in the system 300 registered recipient device 306 can optionally by means of the computer system 304 be or will be verified. The or each resisted and verified receiving device 306 can, for example, from the mobile radio device without further requirements 102 can be displayed, e.g. by means of the application 452 . Optionally, the user can 104 the voting decision is provided, one or more than one registered and / or verified recipient device 306 individually to deselect (also referred to as opt-out) or to prefer (opt-in), e.g. to mark as a favorite. This achieves, for example, that a less trustworthy security provider is not called for help first.

The user 104 the voting decision can thus be made available to which receiver device 306 or in what order the message 106 to multiple receiving devices 306 should be transmitted. Alternatively or additionally, the user can 104 the voting decision will be provided, the message 106 to one not in the system 300 registered recipient device (also known as an unregistered recipient device). The user can clearly 104 choose your own security provider. Optionally, the voting decision can include the unregistered recipient device 306 to assign an area of responsibility. Mutual authorization of the mobile radio device is optional 102 and the unregistered recipient device. This ensures that the security provider of the unregistered recipient device is also aware that and by whom he is being called for help. The message 106 is only transmitted to the unregistered recipient device, for example, if it is available and within the area of responsibility assigned to it.

Furthermore, the computer system 304 or a corresponding application (also referred to as a receiver device application), which makes it possible to switch the corresponding (registered or unregistered) receiver device between available and unavailable and / or its location to the computer system 304 to submit. The receiving device application can illustratively be the counterpart to the application 452 and the mechanism described herein on the receiving device 306 to implement.

For example, the computing system 304 by means of the receiving device application that is executed on the receiving device, the availability (e.g. reachability) and / or the location of the receiving device 306 determine. Alternatively or additionally, the recipient device application can check the availability (eg reachability) and / or the location of the recipient device 306 to the computer system 304 Submit and / or update periodically.

Becomes a receiving device 306 from the message 106 not reached or is its connection to the network 302 interrupted, the emergency contact can be alerted as a fallback level 111 . In the case of a security provider emergency call contact, this step only takes place if there is no availability area in which the mobile device 102 is assigned to the receiving device 306 reports back or none are available in the availability area. If at least one receiver device 306 can be reached, the alarm can be triggered 111 done by sending a push message 106 for all receiving devices assigned to the availability area 306 is delivered. This ensures that at least one helper has an Internet connection and can receive the alarm. Alerting 111 can alternatively or additionally via SMS message 106 take place (e.g. in the event of an unsuccessful push message 106 and / or for the purpose of redundancy).

A push message 106 for example, one can be sent to the application 452 addressed message (e.g. assigned to the user ID), the content of which is in response to receipt by the device 102 , 306 which is the push message 106 receives, is displayed, for example regardless of which application (s) are being executed by the operating system in the foreground at this moment. The content of the push message 106 can from the application 452 be transferred to the operating system (by means of a programming interface), the operating system taking over the display of the information.

Optionally, the receiver can select that receiver device 306 the closest spatial distance (via GPS, Bluetooth, indoor radio beacons, and outdoor radio beacons) to the mobile device can be selected 102 having.

Should this receiver device 306 unavailable, unreachable, or otherwise unresponsive to the message 106 respond, the message can automatically be sent to the next recipient device 306 be transmitted. Cannot receive a receiving device in this order 306 be found that on the message 106 responds, the emergency contact can be alerted as a fallback level 111 will.

Was alarming 111 carried out, the defusing criterion can optionally be modified (also referred to as an extended defusing criterion). For example, the expanded deactivation criterion can be met if, as an alternative or in addition to the touch pattern described above (eg a touch gesture), a user input occurs, eg by touching the mobile radio device 102 . The user input can be used, for example, to authorize the user 104 take place (also known as user authorization). This can be vividly disarmed 105 Can only be done when the user is 104 authorized, e.g. by means of a code.

9 illustrates a cellular device 102 in a schematic plan view 900 analogous to plan view 400 when the cellular device 102 in the standby mode 109 is.

In the event that the user 104 has the impression of potentially losing control of his or her actions (for example, by taking knockout drops), the choice can be made available to him when the standby mode is activated 109 the period 201 (also referred to as timer), ie to activate the timer. For example, the arming criterion can be met if a user input is made that specifies the period 201 indicates. For example, the application 452 Offer a range of time periods from which the user can choose 104 the period 201 selects. Furthermore, a voting decision can be provided, by means of which, when the timer is activated, the period of time can be prevented 201 expires, e.g. by extending it or disarming it 105 is carried out. The disarming 105 can only be carried out, for example, if the extended mitigation criterion is met.

This mechanism makes it possible to raise the alarm 111 perform when control of the situation is unexpectedly lost. This can be the case, for example, when taking so-called "knockout drops".

A timer can be clearly activated, which automatically triggers the alarm after a personally defined period of time (e.g. 2, 5 or 10 minutes) 111 triggers. The symbol 406 of the marker 412m can, for example, show how long it will be until the period 201 has passed. If the user 104 If the timer does not cancel, you can activate it shortly before it expires by vibrating the mobile device 102 , by means of a call or a push message 106 be advised that the alarming 111 is imminent. Should the user 104 not reacting to it, the alarming will be 111 carried out. If his situation has improved and he continues or regains control of the situation, he can defuse it 105 perform, e.g. by authorizing himself to cancel the timer.

10 illustrates a cellular device 102 in the standby mode 109 in a schematic plan view 1000 analogous to plan view 400 when the cellular device 102 asks for a user input to meet the (eg extended) mitigation criterion with which the user 104 is authorized. In response to the fulfillment of the defusing criterion, for example, defusing 105 can be carried out, e.g. the timer can be canceled. In order to meet the deactivation criterion, the user can 104 for example, enter a multi-digit (e.g. four-digit) numerical code previously defined by him and / or the solution to a task displayed to him (e.g. image-based) 1002 enter. The task 1002 can, for example, consist of selecting an object (e.g. an image) that is known to the user at least twice in succession from among four options. If the entry is correct, the user can 104 are considered authorized.

An example of a picture-based task 1002 may have a user 104 correctly enter known playing card of a French card sheet for authorization. The task 1002 can consist, for example, in selecting the color of the known playing card from a first row of displayed fields and selecting the value of the known playing card from a second row of displayed fields. Which color / value is displayed in which field is arbitrary and is randomly drawn every time.

For example, a probability of randomly selecting a combination of 1 out of 4 choices twice can be approximately 6.25%. The corresponding coverage is approximately 93.75%.

11 illustrates a system 1100 , e.g. the system 300 to carry out the procedure 100 or 200 according to various embodiments in a schematic communication diagram. The system 1100 can be a radio beacon 308 have which are in an availability area 1102 is arranged and whose signal den Availability area 1102 covers (then also referred to as the safety area). For example, the security area 1102 have the entrance door to a building, which is not only physically protected by a helper but also protected by a digital lock. The message 106 can be sent to the receiving device 306 (e.g. the corresponding security force) are transmitted as soon as a user is present 104 in the security area 1102 resides his mobile device 102 for example in the standby mode 109 is, for example, counts down a timer that is still active. Alerting 111 can be done, for example, when the mobile device 102 the presence of the radio beacon 308 has captured. The user 104 the mobile device is thus provided with the voting decision 102 to transform into an alarm device that acts like an anti-theft device in a retail shop and kicks in as soon as someone tries to enter the security zone with a mobile device 102 to traverse.

The radio beacon 308 can be a radio beacon that is permanently connected to the building and is supplied with energy by cable, for example. Alternatively or in addition, the radio beacon can be a mobile radio beacon that has a battery for power supply.

12th illustrates a system 1200 , e.g. the system 300 or 1100 to carry out the procedure 100 or 200 according to various embodiments in a schematic communication diagram. About communication within a security area 1102 even if the connection is bad (eg broken) 301 with the network 302 can ensure alarming 111 have the radio beacon 308 instruct the message 106 to the network 302 to submit.

For example, the mobile device 102 (e.g. the application 452 ) to alert 111 act as a radio beacon and thus independent of the connection 301 from the stationary radio beacon 308 recorded (e.g. located). The user ID of the user can be used to prevent misuse 104 together with the mobile phone number of the mobile device 102 (or other data from the mobile device 102 and / or user 104 ) and an optional checksum can be used as Beacon ID (Bacon identifier). For example, in the event of abuse, a mobile radio device can be used based on this 102 and / or the user 104 be blocked.

In response to this, the stationary radio beacon 308 the message 106 produce 111 and / or send, the message optionally including an indication of a distance to the mobile radio device 102 from the stationary radio beacon 308 (and thus an indication of its location), and / or at least has the alarm indication to indicate that an alarm has been triggered 111 is done nearby. Alternatively or in addition, the recipient device application can use the recipient device 306 the radio beacon 308 to implement. This allows the receiving device 306 can be used as a mobile radio beacon.

For example, the message 106 from the mobile device 102 generated and sent to the radio beacon 308 which is the message 106 to the network 302 forwards. This can alarm 111 clearly “piggyback” via the radio beacon 308 transmitted even if the cellular device 102 no Internet connection 301 owns. Optionally, other data can be forwarded from the mobile radio device in the same way 102 take place, for example its location and / or the surrounding data.

13 illustrates a radio beacon 308 to carry out the procedure 100 or 200 according to various embodiments in a schematic structure diagram 1300 . The radio beacon 308 can in contrast to a permanently installed radio beacon 308 provide a flexible, stand-alone hardware solution to a mobile security area 1102 to be able to provide.

The radio beacon 308 may have: a warning light 1302 that has, for example, a lamp (general lighting device) that signals that an alarm has been detected 111 within the security area 1102 was recorded; an optional photovoltaic component 1304 (e.g. a solar cell) in order to be able to function autonomously without a power grid (e.g. at festivals); an audio component (eg a tone generator) which is set up to emit a loud noise to draw attention to an emergency (eg of at least 100 decibels); a radio receiver 1306 for receiving different signals according to a radio standard (eg Bluetooth); an optional radio transmitter 1308 to forward the message 106 (and thus increasing the range) and / or for communication with the mobile device 102 . The radio transmitter 1308 and / or radio receiver 1306 (together or individually also referred to as a transmitter) can for example be set up for communication according to one of the following wireless KP: a WLAN-KP, a long-distance WAN-KP (LoRaWAN-KP), a Bluetooth-KP, a point-to-point Point over Network KP (PPPoE KP). The LoRaWAN-KP can, for example, provide more range than the WLAN and / or less than a cellular standard (for example 3G, ie the third generation).

Using the PPPoE-KP and / or the LoRaWAN-KP, the message 106 to the internet 302 to get redirected. Alternatively or additionally can forward the message 106 according to the Bluetooth-KP (clearly as a fallback level, if the application 452 cannot communicate independently over the Internet).

The transmitter 1306 , 1308 (the radio transmitter 1308 and / or radio receiver 1306 having) can, for example, a short-range transmitter for communicating with the mobile radio device 102 have (e.g. via Bluetooth, WLAN or LoRaWAN). Alternatively or additionally, the transmitter 1306 , 1308 may have a long-haul transmitter to communicate with the computing system 304 (e.g. via cellular mobile network).

The radio beacon 308 can alternatively or in addition to the photovoltaic component 1304 a battery 1310 or have another self-sufficient energy supply.

14th illustrates a system 1400 , e.g. the system 300 , 1100 , 1200 or 1400 to carry out the procedure 100 or 200 according to various embodiments in a schematic communication diagram. In the system 1400 can the receiving device 306 analogous to the mobile device 102 set up and associated with it (also as linked mobile devices 102 , 306 designated). For linking two or more cellular devices 102 , 306 mutual authorization can take place. Alerting 111 can then have the message 106 to each of the linked mobile devices 102 , 306 to be transmitted, for example by means of a direct communication link between them and / or according to a short-range wireless KP.

The user 104 For example, when recording the surroundings, the voting decision can also be made available as a preliminary stage for alarming 111 by means of the network 302 , a linked cellular device 102 to alert, for example, a private person he trusts in his vicinity. For example, several guests could digitally network and take care of each other for an evening together in a night club.

Each of the linked cell phones 102 For example, the last recorded location of the other linked mobile radio devices can be provided 102 retrieve. The group of linked cellular devices 102 can, for example, define (e.g. by means of a common radius) how far apart they want to be. If a cellular device 102 of the group exceeds the common, maximum defined distance from one another, then each of the linked mobile radio devices 102 receive and / or output corresponding information about it. Optionally, the battery charge status of the linked mobile devices 102 can be viewed among each other and / or a push notification can indicate a low battery level of another mobile radio device 102 inform the group.

If one of the linked cellular devices 102 into standby mode 109 toggles (or alarming 111 triggers), all mobile devices can 102 the group can be informed about this (e.g. via push notification).

15th illustrates a cellular device 102 to carry out the procedure 100 or 200 according to various embodiments in a schematic structure diagram 1500 . The cellular device 102 can have one or more than one processor 1402p (e.g. the ARM architecture or x86 architecture), a data store 1402s and several sensors 1404s and also have a battery 1402b (e.g. accumulator) to supply them with electrical energy. Furthermore, the mobile radio device can have a communication bus, which the processor 1402p , the data store 1402s , and the multiple sensors 1404s communicatively connects with each other.

Furthermore, the mobile radio device can by means of the processor 1402p an operating system 1412 such as Windows, iOS, Google Chrome OS, Android, Blackberry OS, WebOS, KaiOS or Linux. The operating system 1412 can implement, for example, application management, memory management, file management and / or rights management and also one or more than one programming interface for connecting applications to the operating system 1412 exhibit. Furthermore, the mobile device 102 one or more than one application 1410 (e.g. the application 452 and / or the receiver device application) which by means of the processor 1402p is executed and / or on the operating system 1412 running. The or each application 1410 can optionally on the data store 1402s be saved. The data store 1402s can for example have a volatile and / or non-volatile data memory, eg a USB stick, a flash memory, RAM (random access memory), DRAM (dynamic RAM) or EPROM (erasable programmable read-only memory).

A programming interface can be set up to connect one or more than one application to the operating system and provide one or more than one operating system functions. An operating system function can, for example, be set up to at least return data from the operating system or to store data when it is called.

Optionally, the mobile radio device can have one or more than one user interface 1414 (e.g. user input interface and / or user output interface), e.g. a screen (also referred to as a display device), a physical keyboard, a loudspeaker, a vibration device, one or more than one physical switch (e.g. button) or the like. The multiple sensors 1404s can for example have a localization sensor, a microphone, a touch sensor, an optoelectronic sensor, a position sensor, a magnetic field sensor, an acceleration sensor or the like. The operating system 1412 can be set up to each one of several sensors 1404s and / or any user interface 1414 to control (e.g. read out) in order to interact with the user (e.g. accept user input and / or output information). The operating system 1412 can for example provide information (by means of a corresponding programming interface) and / or update it periodically which represents the data read out by a sensor or a user interface. The touch sensor can optionally be set up, at least one property of a touch of the mobile radio device 102 to determine, for example their location and / or trajectory (or more generally spatial distribution), their intensity (e.g. pressure and / or area), their duration and / or frequency (or more generally temporal distribution). The property (s) of the touch can, for example, be translated into a touch pattern in order to compare this with the touch criterion.

16 and 17th each illustrate the display device 112 (also referred to as a display) of a mobile device 102 in different schematic plan views 1600 to 1700 analogous to plan view 400 while performing the procedure 100 , 200 . The initial state of the mobile device 102 , e.g. when the application 452 is the sleep mode 107 .

In 1600 can display 112 for example the home page of the application 452 with a virtual slider as the central control element 402s is provided by means of the start page, its state by touch (e.g. with the user's finger 104 ) and horizontal movement of the point of contact (also known as stroking movement) can be changed. The internal status of the slider is determined by the swiping movement 402s (also referred to as controller status) changed between the values 0% (touch all the way left) and 100% (touch all the way right). The stroking movement can, for example, only be registered if it is also at a position on the slide control 402s begins, which is the current state of the slider 402s corresponds. The status of the slider 402s indicated by the position using the marker 412m (also referred to as controller or status indicator) is marked. The position of the controller can thus be illustrated 412m be guided with the finger between 0% and 100%. As long as the finger is motionless on the controller 412m is held, the status of the slider changes 402s Not.

A previously greyed out video symbol is optional 416 and / or alarm symbol 426 highlighted when the controller status exceeds a respective threshold value in order to additionally visualize the current controller status. If the controller status is brought back below the respective threshold value, the corresponding 416 , 426 Icon grayed out again. The alarm symbol 426 is highlighted, for example, from a controller status above the threshold value of 0%.

The application 452 can react to any change in the controller status with an action. In sleep mode 107 are in the info area 1606 the display 112 for example information 412s to locate the mobile device 102 displayed (e.g. based on geolocation 101 of the mobile device 102 ). Alternatively or additionally, the context area 1607 the display 112 a map with your current position 412s of the mobile device 102 Show.

From 1600 to 1700 the controller state is brought above a first threshold value of 25%, whereupon in response to the standby mode 109 switched 105 can be and optionally in addition to the location 101 of the mobile device 102 a video recording by means of the mobile radio device 102 can be done. The video symbol is optionally used as an additional visualization 416 highlighted. If the controller status is brought above a second threshold value of 70%, the mobile device is supported by LED lighting 102 turned on so that the user 104 can control the illumination of the video recording without an additional control element.

From 1700 to 1600 the controller status is brought back to the far left (0%) and the touch is then interrupted, e.g. the marker 412m let go. In response to this, interaction with the user can take place 104 end without being alarmed 111 takes place, and / or it can be the mobile radio device 102 into sleep mode 107 be switched. If the controller status in 1700 is brought to any other value other than 0% and the touch is then interrupted (ie the status of the slider 402s is greater than 0%), the alarm can be triggered 111 take place, for example, alarming 111 addressed to a security service or the police.

Via a virtual menu switch 1709 (also known as the menu button) of the mobile device 102 can the user 104 Access additional pages and dialogs, for example for settings or help. The menu displayed can only be accessed using the menu switch, for example 1709 open to prevent accidental operation.

18th illustrates the process 100 or 200 to operate the system 300 , 1100 , 1200 , 1400 according to various embodiments in a schematic flow chart 1800 .

The system 300 , 1100 , 1200 , 1400 can be server-side 304 work with anonymized data as much as possible. Every request to the computer system 304 can using the user ID of the user 104 , which has a unique identifier (e.g. a character string). The user ID can be used when starting the application for the very first time and / or immediately after installing 452 from the mobile device 102 to be generated.

The user ID can be given to the user 104 identify, ie be clearly assigned to this, but do not allow any conclusions to be drawn about his person. For example, the user ID can have one or more than one UUID (“Universally Unique Identifier”) or be formed from it (for example the character string 7e129414-76b9-4000-9d9f-1c399944759f). For example, the user ID can have two UUID concatenated with a minus sign (for example, resulting in the character string 7e129414-76b9-4000-9d9f-1c399944759f-e46a9c7e-163e-4caf-986e-81f3b06590bc).

While using the mobile device 102 (e.g. the application 452 ) can use GPS coordinates of the mobile device 102 server side 304 be logged. The localization that takes place 101 (eg by means of geo-localization) and the associated monitoring can be a basic function of the mobile radio device 102 (e.g. the application 452 ) and basic benefits for the user 104 . The user must provide details about himself 104 do not reveal this.

The recording of the surroundings (for example video surveillance) can be carried out using the user ID and / or the current GPS coordinates of the mobile radio device 102 be referenced. The user must also do this 104 do not reveal any details about himself.

For alerting 111 (eg for security forces) the anonymous user ID is not always sufficient, eg if there is a risk of deliberate misleading or malicious attacks on the system 300 , 1100 , 1200 , 1400 (e.g. its alerting route) cannot be ruled out. In this case the user can 104 by means of the mobile device 102 asked 1801 to enter a personal information, e.g. his postal address or the mobile phone number of the mobile phone 102 . Optionally, the mobile device 102 and / or the user 104 be verified by the system using the personal information 300 , 1100 , 1200 , 1400 . The confirmation takes place, for example, in a form that does not require permanent storage of the mobile phone number on the computer system 304 gets by.

The user 104 can also be prompted to enter the mobile phone number directly 1801 will. The mobile phone number can, for example, be sent to the computer system without the otherwise usual specification of a user ID (also referred to as a user handle) 304 transmitted 1802 will. The computer system generates based on this 304 a random multi-digit (e.g. 4-digit or 8-digit) alphanumeric string 1803 and transmitted 1804 this (e.g. via an SMS service provider) to the mobile phone number. The transmission (e.g. SMS) can be the character string 1803 itself and / or a UDL (universal deep link) which has the character string. The UDL can be touched directly from the mobile device 102 (e.g. the application 452 ) can be opened.

The mobile phone number and the random character string are stored in a database of the computer 304 temporarily saved 1805 , e.g. for 5 minutes or less. Receives for authentication 1806a the cellular device 102 the transmission (e.g. the SMS) and / or the user 104 gives 1806b the random string manually into the mobile device 102 a (e.g. by application 452 ). The random character string is sent to the computer system together with the user ID and the mobile phone number 304 transfer 1807 , e.g. by means of the network 302 . Do the mobile phone number and the random string match the server-side 304 stored information match, a signature can be used in response 1808 generated on the basis of the user ID and the mobile phone number and sent to the mobile phone 102 transmitted 1808 will. The signature can, for example, have or be formed from a cryptographically signed tuple of user identification and mobile phone number.

Optionally, the in 1805 stored information (s) are deleted. As an alternative or in addition, an MD5 sum of the mobile phone number can be sent from the computer system together with the user ID 304 saved 1809 to be alerting 111 even with calls one user 104 to be able to assign, e.g. if the mobile phone number of the computer system 304 itself is not known.

The signature can also be from the mobile radio device 102 saved 1809 e.g. in a non-volatile memory (e.g. by means of the application 452 ). This process enables the user ID and the mobile phone number to be stored in the main memory of the computer system only for a brief moment 304 and are not stored persistently. From the log files of the computer system 304 the user ID and / or the mobile phone number are filtered out or simply not stored in them. In general, as an alternative or in addition to the cell phone number, another address can be used at which the user 104 can be reached (e.g. an e-mail address, a network address, an instant message address or the like). The address can for example with the mobile device 102 or at least the user 104 be associated.

The user ID, the mobile phone number and the signature can only be used when the alarm is triggered, for example 111 (e.g. the security forces) are transferred together, for example if the possibility of a clear identification of the user 104 in his person or at least via his mobile phone number (e.g. for a callback). The mobile phone number can, for example, be the lowest common denominator for working with a security service or the police.

The user 104 can optionally add the system 300 , 1100 , 1200 , 1400 one or more than one additional information about his person, for example by means of an input on the mobile radio device 102 , e.g. via the settings of the application 452 . The type and / or scope of the input remains with the personal data protection requirements according to the setting of the application 452 left. The one or more additional information can, for example, be a name, an age, a gender or one or more than one photo for the identification of the user 104 exhibit. The one or more than one additional information can optionally be used when alarming 111 by means of the message 106 be transmitted and / or does not necessarily have to be transmitted by the mobile radio device 102 be validated.

19th illustrates localization 101 (eg by means of geo-localization) according to various embodiments in a schematic flow diagram 1900 , where localizing 101 a readout 1900a and / or tracking 1900b may have.

The reading out 1900a can have, by means of a first operating system function of the mobile radio device 102 continuously (e.g. periodically) by the operating system 1412 of the mobile device 102 read provided location data 1901 (e.g. while the application is running 452 ). The operating system 1412 of the mobile device 102 can determine the location data, for example, based on GPS satellite information, the network topology of the network provider and / or a known WLAN access point. The location data read out by the operating system function (eg GPS coordinates) can be further processed and subjected to an optional reverse address search using a second operating system function 1902 . Based on the reading result 1900a For example, the location information can be determined.

The tracking 1900b may have to implement a beacon scanner by means of a third operating system function 1903 (e.g. by means of the localization sensor 102a) that is set up, one or more than one beacon 308 to determine which one the system 300 , 1100 , 1200 , 1400 sends out assigned identifier. If one or more such beacons 308 determined 1904 their details can be used to determine the location. A beacon 308 can for example be an iBeacon or Eddystone beacon, as will be described in more detail later.

The from 1901 , 1902 and or 1904 The data provided (e.g. geographic information) can be added to the location information 1915 merged 1905 , e.g. be consolidated. Change the data from 1901 , 1902 and or 1904 can specify the location 1915 updated and optionally compared with the previous status. If the location is 1915 has changed significantly, a call to a geo-service of the system 300 respectively 1906 for their further processing and / or presentation as location information 412s . With a significant change in the location information 1915 for example, a change in location 151 of the mobile device 102 (e.g. its GPS coordinates) by more than a meter, a changed postal address, a change in the closest beacon 308 and / or a change to the closest beacon 308 be understood by more than a meter.

The geo-service can (e.g. all) the mobile device 102 Obtain available geographic information as location information and, in response, the metadata for a responsible recipient device 306 (e.g. the security service provider and / or the police) as a fallback level back to the mobile device 102 to transfer. For the most realistic possible determination of a responsible receiver device 306 (e.g. of the security service provider) can database-supported building information, responsibilities and duty rosters of security service providers, location information from beacons 308 and / or current GPS coordinates of receiver devices 306 be recorded and included.

Could from the operating system 1412 of the mobile device 102 no location data (e.g. GPS coordinates) are made available, so localization can take place 101 only by means of, if possible, one or more than one recorded beacon 308 respectively. The location of the or each beacon stored in a database of the system 308 can be evaluated and the location of the mobile device 102 can be determined based on this, for example by means of a triangulation of the signal strength of several detected beacons 308 . The system's geo-service can use one or more than one beacon 308 to locate 101 also a postal address to the mobile device 102 submit when the operating system 1412 of the mobile device 102 does not implement address resolution itself.

20th illustrates the environment recording according to various embodiments in a schematic flow diagram 2000 which has, for example, the acquisition of video data, the video data having at least image data and optionally audio data. What is described here as an example for the video data can also apply analogously to photos and / or only audio data.

The recording of the surroundings can have the video camera of the mobile radio device via a fourth operating system function 102 to initialize 2001 and the processing of the video data by means of the application 452 to enable. The ones from the operating system 1412 of the mobile device 102 The provided video data can be used in parallel for video transmission over the network 302 processed 2002 and optionally by means of a fifth operating system function locally on the mobile radio device 102 get saved.

Are the locally stored video data at risk of deletion by a third party and / or an interruption when the local storage capacity of the mobile device is used up 102 exposed, these can optionally be connected to the computer system 304 be transmitted (e.g. with or without on the mobile device 102 to be saved) and saved by it. The redundant storage locally and on the computer system 304 compensates, for example, the risk of a network failure and thus enables increased data security.

Transferring 2002 the video data is sent, for example, in packets via the RTMP protocol (Real-Time Messaging Protocol) to the computer system 304 or to a video service provided by them and can be accessed by the computer system 304 that transcodes a streaming format, e.g. an HLS format (Hypertext Transmission Protocol Live Streaming Format) 2003 will. The RTMP protocol is particularly suitable for repeated use in the event of connection interruptions and counteracts incorrectly transmitted video data from compromising the entire data transmission.

The streaming format (eg HLS format) can save individual video fragments as independent files (so-called chunks), from which a digital fingerprint can be determined for each file 2004 . Each fingerprint, together with a time stamp of the respective video file, can be sent asynchronously to a fingerprint service of the computer system 304 and transmitted by this to one or more than one external storage devices (also referred to as external storage). The system secures the external storage 300 , 1100 , 1200 , 1400 against data manipulation and / or can at least provide that data manipulation, for example by an employee of the system 300 is carried out, can be revealed (or at least reversed) externally.

21st illustrates alarming 111 according to various embodiments in a schematic overview 2100 in which the connection 2111 of the mobile device 102 , the connection 2112 of the receiving device 306 and the guy 2113 of the KP (clearly showing the alarm path). Transferring 111 the message 106 depending on the availability of an Internet connection and / or depending on the accessibility of the receiving device 306 (e.g. the security forces) according to one or more than one CP 2113 respectively.

Are both, the cellular device 102 and the receiving device 306 , with an internet connection 302a connected, the message can 106 in the form of a text message 2101a to the receiving device 306 be transmitted. The text message 2101a can for example be a push message or an SMS. Transferring the text message 2101a to the receiving device 306 can by means of the computer system 304 respectively. The text message 2101a can indicate the location of the mobile device 102 exhibit. The receiving device 306 can optionally be or will be provided, a video transmission to the mobile radio device 102 to initiate, for example by means of the recipient device application. A helper can clearly start a video stream to get an impression of the current situation of the user 104 to get.

Is the receiving device 306 however, the message can only be reached by telephone (ie by voice message) 106 in the form of a voice message 2101b to the receiving device 306 be transmitted. For example, a telephone call to the security forces can be clearly initiated, through which an alarm is given by telephone to the user 104 is made possible. Is the cellular device 102 with the internet connection 302a connected, can optionally in addition to the voice message 2101b a message 106 from the mobile device 102 to the computer system 304 (also referred to as internal alarming), for example to be able to provide evidence afterwards.

Independent of a connection to the telephone network 302b and / or the internet connection 302a can alternatively or additionally contain the message 106 in the form of a bluetooth message 2101c using a Bluetooth connection 302c to the receiving device 306 be transmitted. The mobile device can do this 102 (e.g. from the application 452 triggered) implement a beacon (also referred to as beacon mode) and can thus be recognized by a beacon scanner in the vicinity.

22nd illustrates alarming 111 by text message 2101a according to various embodiments in a schematic flow chart 2200 .

Alerting 111 by text message 2101a can be sent to the recipient device by means of a push message 306 done, and in the event that this is not sent to the receiving device 306 can be transmitted using the SMS. Alerting 111 by text message 2101a can be done when the cellular device 102 and the receiving device 306 are connected to each other by means of an Internet connection. The cellular device 102 can alarm 111 carry out 2201 (e.g. by means of the application 452 ), e.g. by adding the message 106 to the computer system 304 is transmitted. The message 106 can optionally include the user ID, the (e.g. validated) cell phone number of the cell phone device 102 and / or have the associated signature. The computing system 304 can check the mobile phone number by comparing it with the user ID and the signature 2202 . The computing system 304 can the message 106 for example, discard if the comparison does not match. If the comparison results in a match, information about the receipt of the message can be provided 106 stored in a database 2203 and one for the location of the mobile device 102 responsible receiving device 306 can be determined, which is then via push message 2101a is informed about it 2204 that alarming 111 has taken place (e.g. together with the location information). It is determined that the push message 2101a unsuccessful to the receiving device 306 the receiving device can 306 by texting 2101a be informed about it 2205 that alarming 111 has taken place (e.g. together with the location information).

At reception 2207 the message 106 from the receiving device 306 can be assigned to the user of the receiving device 306 the choice to be or will be provided (e.g. if this is in response to 2205 , 2204 the recipient device application opens) whether he is receiving the message 2101a positively or negatively acknowledged 2208 (clearly follows the call for help or not). If the acknowledgment is positive, the receiving device can 306 the event of the alarm 111 through the cellular device 102 assigned 2207 and information about this is stored in the system's database. If there is no or a negative acknowledgment (e.g. within a few minutes), the message can 106 to another receiving device 306 shipped 2209 e.g. to inform the police or a background service of the responsible security service provider. Should the receiving device 306 Do not have an Internet connection, so can make a phone call with a voice message 2101b (clearly an announcement) to the receiving device 306 be judged. The voice message 2101b can be analogous to text message 2101a the location information, the alarm information and optionally the mobile phone number of the mobile device 102 to transfer.

In the event of a telephone alarm 2101b can optionally have a conversation between the user 104 and the user of the receiving device 306 be initiated. Alerting 111 does not necessarily have to be done using the computer system in this case (e.g. if there is no internet connection) 304 can take place, but from the mobile device 102 (e.g. the application 452 ) are logged and the content of the log is sent to the computer system 304 transmitted as soon as there is an internet connection.

23 illustrates alarming 111 via bluetooth 302c (also called Bluetooth alarming 111 designated) according to various embodiments in a schematic flow diagram 2300 . Bluetooth alerting 111 can alternatively or additionally to the alarming 111 via internet connection 302a and / or by telephone network 302b respectively. Bluetooth alerting 111 for example, one or more than one beacon 308 use (also as beacon alerting 111 labeled) to even without an internet connection 302a or telephone network 302b a receiving device available in the local area 306 the message 106 feed. The receiving device 306 can for example be one with the mobile device 102 linked mobile device 102 his.

The beacon alerting 111 may include sending the message 106 from the mobile device 102 (e.g. by means of the application 452 ) occurs several times (e.g. periodically). In other words, the mobile device can 102 implement a beacon transmitter. As an alternative or in addition to the alarm information, the message can have information (also referred to as readiness information) that the mobile radio device 102 armed 105 is (i.e. in the standby mode 109 is switched), e.g. in response to arming 105 . Before the alarm 111 takes place by transmitting the alarm information, for example, the readiness information can be transmitted. The sending 111 the message 106 (having the alarm indication and / or the readiness indication) can for example be clocked, for example every 200 milliseconds. Optionally, one or more than one personal information of the user can be used together with the information 104 be sent.

A receiving device 306 (e.g. its application 452 and / or receiver device application) in the local area of the mobile radio device 102 can implement a beacon scanner, and the message 106 (having the alarm indication and / or the readiness indication) received.

The beacon alerting 111 does not necessarily require an internet connection. For example, the use of Bluetooth 302c provide a range of direct communication between beacon transmitter and beacon receiver of up to approximately 100 meters. However, obstacles between them can reduce the range.

The readiness information can be received, for example, from the receiving device 306 be signaled. The security provider can clearly see that the user is “unwell” 104 be informed in the immediate vicinity. The alarm takes place 111 , can be a push message 2101a to the receiving device 306 be transferred, for example to request the security force.

Is the cellular device 102 in the sleep mode 107 , the mobile device can 102 do not implement the beacon transmitter 2301 . For example, while the user can 104 in the application 452 the slider 402s not served or the marker 412m is below a certain threshold, the application 452 not yet working as a beacon transmitter and there is no signaling 2301 . Switches the mobile device 102 into standby mode 109 um, the beacon mode can be started. Becomes the threshold of the slider 402s exceeded, the application 452 for example implement the beacon transmitter 2302 . The cellular device 102 behaves depending on the operating system 1412 for example as an iBeacon or an Eddystone beacon and transmits the readiness information and / or details about the user 104 (Clearly as a low escalation level before the alarm is raised 111 he follows).

By means of the readiness information, the recipient device 306 the “discomfort” of the user 104 be signaled in the closest local area 2303 . Notification of the receiving device 306 (eg a security guard) by means of the readiness indication can according to a setting of the receiver device 306 take place (or not take place) and does not necessarily have to be acknowledged by him (e.g. in contrast to receiving the alarm information).

The alarm takes place 111 , the receiving device (e.g. its receiving device application) can respond 2305 then display a push notification 2305 . When the user 104 the disarming 105 (if necessary only if the extended mitigation criterion is met), you can go back to 2305 can be changed or the beacon mode can be ended 2306 will. If the beacon mode is ended, this can be done by the system (e.g. the receiving device 306 ) can optionally be interpreted as a false alarm. If this time is exceeded, the alarm can be triggered 111 remain active, even if there is no further signaling or operation of the mobile radio device 102 (e.g. by the user). As long as the alarm 111 is active, the message can 106 be sent repeatedly with the alarm indication.

In analogy, the transmission of the message 106 to a linked mobile device 102 respectively. The linked mobile device 102 can initially receive the readiness information. In this case, the linked mobile device can 102 however, be prepared to respond only then 2305 if the readiness information from a linked mobile device 102 originates. The linked mobile device can be clearly illustrated 102 (e.g. its application 452 ) only on those mobile phones 102 respond to their user ID with the mobile device 102 linked (that is, the part of the linked cellular device group 102 are). Other cellular devices that are not part of the group can use the cellular devices 102 of the group can be ignored. The application 452 In contrast to the receiver device application, it can be set up in such a way that the receipt of the readiness information already indicates the display 2305 the push notification triggers.

The options for transmitting user details differ greatly between iBeacons and Eddystone beacons, which will be discussed below.

The iBeacon standard, for example, does not allow the transmission of additional user data and is therefore only used under iOS for alarming 111 via a Bluetooth connection 302c is used because the EddyStone standard is only supported there for the reception of beacon data. Each iBeacon transmits the proximity UUID (a static UUID for system beacons) as well as a major and a minor ID (e.g. two 16-bit numbers). The latter together allow the addressing of 2 ¹⁶ · 2 ¹⁶ = 4'294'967'296 devices.

To indicate the readiness and the alarm information in the message 106 can integrate the system 300 , 1100 , 1200 , 1400 optionally be set up to use the most significant bit of the major ID as a bit switch (flag). The bit switch can be used to indicate that the mobile device 102 in the standby mode 109 (Bit switch = 0) is (which corresponds to the readiness specification), and that the touch is in the ready mode 109 interrupted (bit switch = 1) (which corresponds to the alarm specification). In this case 2 ¹⁵ · 2 ¹⁶ = 2 '147' 483 '648 device addresses are available. The system 300 , 1100 , 1200 , 1400 can statically assign one of these device addresses to each iOS user and this can be the user ID of the iOS user 104 assign. This assignment can only be made on the server side, for example 304 be provided and / or stored and the validation of an alarm 111 in that case can only be done if that is from the message 106 addressed receiving device 306 currently has an internet connection.

The EddyStone standard defines several variants, of which the system 300 , 1100 , 1200 , 1400 for example, the variant of the Eddystone UID (unique Eddystone identifier) can be used. The 10-byte namespace (“namespace”) contains a static value that represents the beacons 308 of the system 300 indicates. Even with the EddyStone standard, the 6-byte comprehensive instance (“Instance”) cannot be sufficient for the transmission of a user ID. Instead, a device address can be generated in the same way as the iBeacon standard. The assignment of the device address to the user ID can only be done on the server side with the EddyStone standard 304 and the validation of an alarm 111 can only be done accordingly if the receiving device 306 currently has an internet connection. Since the EddyStone standard has a larger number range than the iBeacon standard, additional protection can be provided in this case. For protection, for example, the first 14 bits of the available 48 bits can be used as a checksum for the user ID and the remaining 34 bits can be assigned at random. This makes it even more difficult to guess a valid device address, which makes manipulation more difficult.

In addition to the UID frame, the Eddystone standard can have a so-called TLM data frame (telemetry data frame, ie a protocol data unit on the data link layer). The TLM data frame can be set up for the transmission of telemetry data in the context of the Internet of Things (IoT). The system 300 , 1100 , 1200 , 1400 can, for example, use a standard-compliant byte offset 2 for the battery status. In byte offset 3, the most significant bit determines whether a GPS coordinate or major and minor ID of a beacon is used in other fields 308 of the system 300 should be transferred. The next bit of byte offset 3 indicates whether it is a readiness indication (bit = 0) or an alarm indication (bit = 1). The remaining bits of byte offset 3 contain the number of hops that a packet has taken (e.g. to increase the range of the transmission via Bluetooth). Byte offsets 8 and 9 as well as 12 and 13 can each be evaluated as a 16-bit word. If the most significant bit of byte offset 3 is set, it is interpreted as a GPS coordinate with byte offsets 7, 8 and 9 as latitude and byte offset 11, 12 and 13 as longitude (IEEE 754 Floating point number with two bit exponent and 21 bit mantissa). If the most significant bit of byte offset 3 is not set, then byte offset 8 and 9 contain the major ID and byte offset 12 and 13 contain the minor ID. If the position is unknown, the most significant bit of byte offset 3 is not set and byte offsets 8, 9, 12 and 13 contain the value 0.

Optionally, the transmission range can be increased via Bluetooth, as described in more detail below. Using the Bluetooth alarm mechanism 111 the coverage of areas with poor cellular coverage can be significantly improved. However, you can receive the message immediately 106 be limited to a range of about 100 meters, for example. In the case of immediate reception, the receiving device would have to 306 then have an internet connection to do the alarming 111 to be able to validate. Both of these factors are improved by increasing the range.

The range can be increased by means of a device (also referred to as an extender or range enlargement device) which is set up to receive incoming messages from the system 300 (e.g. beacon packets). For example, a received message (for example, containing the alarm information and / or the readiness information) can be passed on by the extender, for example only if it has a location information (for example GPS coordinates or beacon location information) and / or if this can be supplemented with the location of the extender. The latter can make the localization less precise, but still provide a location information, which, compared to a forwarding without any location information, at least provides a more useful information content. The forwarding takes place, for example, exclusively according to a beacon standard (e.g. the EddyStone standard), which supports the transmission of location information. If the beacon standard (eg the iBeacon standard) does not support the transmission of a location information, it can be provided that at least the first receiving extender can add a location information. To prevent the cyclical forwarding of packets, the TLM data frame can have a hop count, which is incremented with each forwarding. For example, packets with a hop counter greater than four are discarded. If the extender itself has an Internet connection, the message can be coupled into the Internet 302 respectively. Optionally, the mobile device 102 and / or the receiving device 306 be set up to implement the functions of the extender in order to extend the limited Bluetooth range.

24 illustrates the linking of two or more cellular devices 102 , 306 (also referred to as linking) according to various embodiments in a schematic flow diagram 2400 . The linking can include generating an address (also referred to as a linking address).

Linking can be the association of two or more cellular devices 102 , 306 (also as linked cellular devices 102 , 306 referred to), e.g. permanent or temporary. The linked two or more cellular devices 102 , 306 form a group that requires arming 105 (by means of the readiness information) or an alarm 111 (by means of the alarm information) of a mobile radio device 102 the group to one or more than one (e.g. each) mobile device 102 is communicated to the group, e.g. in addition to notifying the security forces

The linked mobile devices 102 , 306 each have access to their current location. Alternatively or additionally, the linked mobile radio devices can 102 , 306 inform each other that the battery is low.

The formation of a pair of linked cellular devices 102 , 306 (e.g. joining a cellular device 102 in an already formed group) is described below. A first cellular device 102 can make a choice (e.g. a corresponding configuration page of the application 452 ) provide 2401 according to which the user 104 is made possible for a second mobile radio device 102 select a time (e.g. 1 minute, several minutes, days, weeks or unlimited). The system 300 , 1100 , 1200 , 1400 (e.g. the first mobile device 102 and / or the computer system 304 ) can create a new group in response to this, to which a runtime is assigned according to the time specification. The system can also 300 , 1100 , 1200 , 1400 (e.g. the first mobile device 102 and / or the computer system 304 ) generate a link address 2402 which is assigned to the group. The link address can, for example, have a resource pointer or be formed from it, for example a uniform resource pointer (URL). The resource pointer can be a system resource assigned to the group 300 identify and localize a website, for example. The linking address can be from the first mobile device 102 to the second mobile device 102 be transmitted, for example by means of a message (eg a text message) or by means of a QR code (ie a two-dimensional code), for example from the first mobile device 102 displayed 2403 is available, printed out or otherwise reproduced.

The resource pointer can have a token (eg a JWT token - "JavaScript Object Notation Web Token") which has information that enables the group to be joined. The resource pointer can, for example, be a ULD which can also be opened by means of a browser, for example if there is no application 452 on the second mobile device 102 is available. The resource opened by means of the browser (eg website) can optionally have a note that enables the application 452 on the second mobile device 102 to install (e.g. download). For example, you can download the application 452 in one or more than one application marketplace (also known as an app store).

25th illustrates the linking according to various embodiments in a schematic flowchart 2500 . Will the link address (directly or via a photo of the QR code) from the second mobile device 102 open 2510 , a confirmation query can be sent in response 2504 take place, for example by means of the application 452 , on the second cellular device 102 . This can be used for security. After confirmation, the link address can optionally be provided on the server side 304 validated 2505 will. If validation is successful 2505 can the second mobile device 102 added to the group. After the runtime has expired, the group can be deleted Can have the consequence that the cellular devices 102 no longer share information with each other.
