Abstract
Description
[0001] The invention relates to an emergency call module.
[0002] It is known from the prior art that emergency call devices, such as those found in elevators, are connected to a control center via an analog line. An analog line, however, has the significant advantage of having its own power supply. Therefore, making an emergency call is possible even in the event of a mains power failure. DE 198 58 664 proposes an emergency call device that utilizes the emergency call function of a commercial mobile network.
[0003] Document WO 2008 096 162 A1 discloses a method for limiting connections in mobile communication networks. US 2005 / 0 227 666 A1, DE 102 04 480 A1, and DE 102 38 805 A1 relate to methods and devices for triggering an emergency call. DE 198 58 664 A1 relates to an emergency call device for elevators. Document US 2004 / 0 094 366 A1 relates to elevator monitoring. Document DE 20 2005 009 642 U1 relates to a wireless local area network for supporting emergency calls. EP 1 506 795 A2 relates to a method for securing communication on underground construction sites. Reference should also be made to 3GPP TS 22.101 9.1.0 (2008-09) and 3GPP TS 22.153 V8.1.0 (2008-06).
[0004] The object of the invention is therefore to develop a device and a method that allows an emergency call to be made even under adverse circumstances.
[0005] The problem is solved by an emergency call module according to claim 1 and a method for operating an emergency call module according to claim 11. Further advantageous embodiments can be found in the following description, the figures, and the dependent claims. The individual features of the various embodiments are not limited to these, however, but can be combined with one or more other features to form further embodiments. Furthermore, one or more features in the independent claims can be supplemented and / or replaced by one or more other features from the following description. The independent claims serve as a suggestion, but are not to be understood as a limitation.
[0006] An emergency call module is proposed for accommodating an emergency call SIM card of a prioritization-capable mobile network that provides a number of priority levels for connections, wherein the emergency call SIM card has a priority level for a connection in the mobile network that is not equal to the lowest priority level.
[0007] It is preferably proposed that an emergency SIM card of a prioritised mobile network which provides a number of priority levels for connections be used, wherein the emergency SIM card is designed as a Universal Integrated Circuit Card (UICC), and wherein at least one International Mobile Subscriber Identity (IMSI) is stored on the emergency SIM card, and wherein the emergency SIM card has a priority level for a connection in the mobile network which is not equal to the lowest priority level.
[0008] The abbreviation SIM stands for Subscriber Identity Module. In this context, an emergency SIM card should also be understood to be a USIM card, where USIM stands for Universal Subscriber Identity Module. A prioritized mobile network is, for example, a mobile network that supports an enhanced Multilevel Precedence and Preemption Service (eMLPP). The International Mobile Subscriber Identity (IMSI) is a combination of numbers and letters stored on the emergency SIM card to uniquely identify it worldwide. This is used, in particular, to uniquely identify a user within the mobile network.
[0009] In prioritized mobile networks, various priority levels are provided. For example, priority level 4 in an eMLPP-enabled mobile network is the lowest priority level, and level 0 is the highest priority level for a mobile subscriber. There are also two priority levels higher than 0, but these are reserved for network services only. The emergency SIM card has a priority level below 4, preferably below 3, further preferably below 2, and most preferably below 1. Priority means that the mobile subscriber can establish a call with priority, for example, if a cell tower is overloaded.Ideally, a mobile subscriber with a higher priority can also displace a subscriber with a lower priority from the cell. This means that the call or mobile connection for the subscriber with the lower priority is terminated if the subscriber with the higher priority attempts to establish a call. A high priority for the emergency SIM card has the significant advantage that, for example, in unusual situations, such as those known to occur on New Year's Eve or during disasters, an unusually high number of connection attempts take place in one or more cells of the mobile network. In such cases, it is absolutely essential that an emergency call takes precedence over a normal phone call. Therefore, the emergency SIM card has the highest possible priority and thus the lowest possible priority level in the eMLPP mobile network.It is understood that in mobile networks with a priority distribution or number of levels that differs from eMLPP, the respective emergency SIM card should have the highest possible priority within that prioritization-capable mobile network. Preferably, the priority should be in the upper third, more preferably in the upper quarter, and preferably at least in the upper fifth of the prioritization levels. The aforementioned eMLPP – enhanced Multilevel Precedence and Preemption Service – is defined by the 3rd Generation Partnership Project: 3GPP TS 23.067, for example, version 8.0.1, to which full reference is hereby made. Another standard is IEEE 802, to which full reference is also hereby made, in particular IEEE 802.1p. Furthermore, EP 1 911 294 B1 describes a system and a procedure by which a call priority is assigned to a connection.EP 1 182 854 B1 discloses a method for establishing a weighted communication link, and EP 1 944 990 A1 describes the routing of calls from a priority-based telecommunications network. Reference is made to these publications in full within the context of this disclosure.
[0010] In one embodiment, the emergency call SIM card is provided for in that it has a number of telephone number storage spaces and that only the telephone numbers stored in the telephone number storage spaces can be dialed using the emergency call SIM card.
[0011] According to one embodiment, the number of phone number memory locations is limited, preferably to one number less than 10, preferably 5 or fewer, and particularly to 3 or fewer. In another embodiment, the phone number memory can also be populated with Uniform Resource Locators (URLs). For example, this allows predefined websites to be accessed via the emergency SIM card, or data to be exchanged on defined resources via the internet. For example, one embodiment provides that certain statuses of the SIM card or connected modules are stored on a computer connected to the internet. Another embodiment provides that a software update of the emergency SIM card or connected modules is performed via the internet. A further variant provides that email addresses can be stored in the phone number memory.For example, a status email can be sent to a pre-defined address.
[0012] In one configuration, the emergency call SIM card prohibits its use with a mobile phone capable of dialing a freely chosen number. Only pre-programmed numbers can be dialed. For example, the memory slots for the phone numbers are freely programmable. In another configuration, at least one, preferably several, and in particular all, phone numbers are pre-programmed in the memory slots. Preferably, at least the European emergency number "112" is pre-programmed. Furthermore, according to other configurations, local emergency numbers for the police, fire department, and / or ambulance service can also be pre-stored. According to a further development, at least one, preferably several, and in particular all, of the data stored in the phone number memory cannot be changed or deleted. This function has the advantage that the emergency call SIM card can only be used in a dedicated emergency call module.Misuse, for example in a mobile phone, can thus be largely ruled out or is only possible to a limited extent, namely for dialing the stored phone numbers. It is also possible in some configurations to completely prohibit the use of the emergency SIM card in a mobile phone through programming.
[0013] Pre-programming memory slots with one or more phone numbers is only possible, for example, in a device that is separate and independent from the emergency system in which the emergency SIM card is used. Such a device is preferably used exclusively as a storage device. Restricted access to this device can further limit the potential misuse of an emergency SIM card.
[0014] In a further configuration, the emergency call SIM card is designed to suppress early media content from the receiving party. Early media content includes information such as hold messages or music played before the receiving party answers a call, as well as answering machine messages provided by the receiving party's network operator. Generally, early media encompasses all data streams transmitted to the caller before the receiving party answers the call. This excludes so-called ringtones, such as the dial tone, the ringing tone, or the busy signal.
[0015] In a further embodiment, it is envisaged that the emergency call SIM card has parameters by means of which behavior in the mobile network can be monitored and / or controlled.
[0016] In one configuration, the emergency call SIM card enables a so-called full-rate or enhanced full-rate mode. This allows for particularly high-quality voice and data transmission. The emergency call SIM card also supports multi-frequency dialing, which enables data transmission, especially to subscribers with analog lines. Furthermore, one configuration of the emergency call SIM card supports data transmission, preferably bidirectional data transmission. This allows data to be transmitted between the caller and the recipient in addition to voice data. Preferably, digital data transmission is used. In another configuration, the emergency call SIM card supports encrypted data transmission.
[0017] One particular design involves assigning the emergency SIM card a preferably unchanging IP address. An IP address is an address on a network, preferably the internet, where IP stands for "Internet Protocol." In one design, the emergency SIM card is assigned an IP address every time it connects to the internet. Another design provides for the emergency SIM card to have a fixed, unchanging IP address, allowing for its unique identification on the internet. In some networks, dynamic IP addresses are reassigned after a certain period. This can lead to a loss of connection to the network. A static IP address prevents the reassignment of the IP address and thus the loss of connection.While a static IP address cannot be assigned to a specific location, it allows for documentation, for example in a control center or on a server, of which emergency SIM card with which fixed IP address is used where. Another option is for the emergency SIM card to have a multicast IP address. This enables, for example, data transmission from a single point to a group. The advantage of multicast is that data transmission can be sent to multiple participants or a closed group of participants without the sender's bandwidth increasing with the number of recipients. Thus, one option allows the emergency SIM card to send an emergency call to more than one control center or call participants via multicast.Furthermore, full reference is made to US 7, 292, 858 B2, which describes a method for communicating with one of a number of devices with the same telephone number.
[0018] Preferably, the emergency SIM card is capable of establishing an internet connection. In a further embodiment, the emergency SIM card is provided to be capable of General Packet Radio Service (GPRS), Code Division Multiply Access (CDMA), or Wide Band Code Division Multiply Access (WCDMA). If, for example, the emergency SIM card is intended for the Global System for Mobile Communication (GSM) standard, then preferably the transmission methods GPRS or CDMA are used. If, on the other hand, the Universal Mobile Telecommunication Standard (UMTS) is intended for the emergency SIM card, then preferably the WCDMA method is used for data transmission.
[0019] In another version, the emergency call SIM card supports roaming. Roaming is defined according to GSM Association Permanent Reference Document AA.39 as the ability of a mobile subscriber to automatically receive or make calls in a network other than their home network. This ensures that the emergency call function remains operational in the event of a loss of connection to the home network, provided a connection to another network is available. The home network is the network to which the emergency call SIM card is originally registered.
[0020] In a further embodiment, it is provided that fault detection and / or functional features intended for ordinary mobile phones are deactivated on the emergency call SIM card.
[0021] In a further embodiment, the emergency call SIM card is designed to be usable exclusively in an emergency call module, preferably one described below. For this purpose, authentication is achieved, for example, by comparing data stored on the emergency call SIM card with data stored on the emergency call module. The emergency call module can also automatically unlock the emergency call SIM card, which must be performed each time the SIM card loses power. A Personal Identification Number (PIN) is required for this purpose. Alternatively, the PIN may be entered manually, for example, by entering it into an interface of the device in which the emergency call SIM card is used.
[0022] As described at the outset, the invention relates to an emergency call module with at least one data interface and at least one telecommunications interface, wherein the telecommunications interface is designed to accommodate an emergency call SIM card, in particular an emergency call SIM card as described above, for connection via a mobile network. The emergency call module has an uninterruptible power supply. For example, a data interface can be understood as an interface for a camera or a sensor. A data interface can also be an interface for a telecommunications connection such as a handset or a telephone. According to one embodiment, the data interface is an analog interface. An analog telephone device can also be connected to the emergency call module via this interface. The emergency call module is versatile in its applications.For example, the emergency call module is intended for use in an alarm system. Another embodiment envisions its use in a system such as an elevator. Yet another embodiment proposes its use in healthcare or elderly care settings. In one such embodiment, the emergency call module would automatically connect a control center or a specific group of people to the person seeking help, for example, by pressing an emergency call button.
[0023] In a further embodiment, the emergency call module features a preferably detachable mobile communication antenna. The mobile communication antenna enables the connection to the mobile network. For example, this antenna can be integrated into the housing of the emergency call module. In another embodiment, the mobile communication antenna protrudes from the housing of the emergency call module. A detachable mobile communication antenna is particularly preferred when the emergency call module is used in enclosed spaces, such as an elevator shaft. "Detachable" means that the mobile communication antenna is not directly connected to the emergency call module. Rather, a wired connection can be provided, for example, allowing installation at a location some distance from the emergency call module. This connection can be made, in particular, by means of a connector for high-frequency applications, such as an SMA connector (Subminiature A connector).For example, the mobile phone antenna is installed outdoors, for example on the outside wall of a building or on the roof of a building.
[0024] The emergency call module features an uninterruptible power supply. This means, for example, that the emergency call module is connected to a power supply network, with the voltage buffered, according to one embodiment, by means of a battery via at least two different power supplies. In another embodiment, buffering is provided by means of a capacitor. Buffering via a fuel cell is also provided in one embodiment. Preferably, the emergency call module is connected to a 230-volt supply or to a local mains voltage. Should the power supply via the mains supply be interrupted, the battery buffer immediately takes over the supply of the emergency call module until the power supply is restored.
[0025] In a further embodiment, the emergency call module has at least one programming interface. This interface allows, for example, the programming of an alarm output or the emergency call SIM card. Specifically, it is provided that the phone number memory stored on the emergency call SIM card can be written via the programming interface. The behavior of the alarm output can also be programmed; for example, the alarm output can be activated when an emergency call button is pressed. Furthermore, it is provided that the alarm output is activated when, for example, a fault condition or a special condition exists in the emergency call module or in the components connected to the emergency call module. In one embodiment, the alarm output can output a binary signal. In another embodiment, the alarm output supports preferably serial data transmission.
[0026] For example, the emergency call module is designed to have an operating status indicator. This indicator can be used to monitor whether a power supply is still available. Furthermore, it can display the battery charge level or the presence of a mobile signal. Specifically, the indicator shows the strength or quality of the mobile signal, such as a GSM or UMTS signal. The indicator can also report any errors. Additionally, the indicator is designed to display various parameter statuses.
[0027] The emergency call module has at least one monitoring unit that monitors parameters of the emergency call module and / or connected components. For example, a battery charge level, power supply, GSM signal, UMTS signal, an error, an emergency button, or similar parameters can be monitored. Preferably, various parameters are polled regularly, with individual parameters, such as the emergency button, being given priority. The monitored parameters can be displayed, for example, via the operating status indicator. Furthermore, it is provided that the alarm output is activated when certain parameters are in specific states. According to a specific configuration, the monitored states are transmitted to the emergency call SIM card. Preferably, the states or a message about the triggering of the alarm signal are transmitted, preferably via the emergency call SIM card, to a call subscriber or a control center.
[0028] In a further embodiment, the emergency call module is designed to accommodate more than one, preferably two, emergency call SIM cards. Preferably, if the network connection of the first emergency call SIM card, for example from a primary network operator, is lost, the functionality of the emergency call module can be maintained by using a second emergency call SIM card, preferably from a secondary network operator whose mobile network is still reachable. Another embodiment provides that the emergency call SIM card supports at least two different mobile networks or roaming.
[0029] In a further embodiment, the emergency call module is provided with a Digital Enhanced Cordless Communication (DECT) module. This enables, in particular, a redundant system. If the mobile network should fail or a connection is not possible, for example due to a damaged antenna, it is still possible to make a telephone call via a wired connection. Furthermore, in another embodiment, a wireless and local network connection is provided, especially for redundancy purposes. Specifically, the emergency call system includes a Wireless Local Area Network (LAN) module.
[0030] An alarm output, which the emergency call module features in one configuration, can be programmed. Specifically, it is provided that an audio or voice output is possible via the alarm output. For this purpose, a loudspeaker or signaling device is connected to the alarm output. In another configuration, the alarm output is connected to the control unit of an alarm system or the control unit of a system, such as an elevator, provided the emergency call module is operated with such a system. Thus, when the alarm output is activated, certain actions can be performed by, for example, a system such as an elevator.Preferably, in one variant, it is provided that an existing wired emergency call connection, for example in an elevator system, an alarm system or other monitoring device, can be replaced or redundantly secured by means of the emergency call module.
[0031] A further aspect of the invention relates to a method for operating an emergency call module, for example the emergency call module described above, with at least one data interface and at least one telecommunications interface, wherein the telecommunications interface is configured to receive an emergency call SIM card – preferably the emergency call SIM card described above – for connection via a mobile network. In an emergency, the emergency call module establishes a connection via a prioritization-capable mobile network that provides a number of priority levels for connections, such as an eMLPP-capable mobile network with at least one telephone number stored in the caller ID memory, wherein a priority level other than the lowest priority level is assigned to a connection in the mobile network by means of the emergency call SIM card.Preferably, a connection is established only to telephone numbers stored in the telephone number memory. It is further preferred that the telecommunications connection is conducted in full-rate or enhanced full-rate mode. Another variant of the method provides for a bidirectional and / or encrypted connection to be established from the emergency call module to a target subscriber.
[0032] A "need" situation is, in particular, an emergency that is detected by the emergency call module. For example, a need is signaled to the emergency call module by pressing an emergency button. However, "need" situations can also include situations in which secure access to a component connected to the emergency call module is required. For example, in one configuration, the emergency call module is connected to a machine. If a fail-safe connection is needed, for example, for controlling the machine, this can be established by the emergency call module. For this purpose, the emergency call module is contacted by a control center, and a high-priority callback is initiated via a mobile network connection. In another variant, at least one defined operating state of a system or machine corresponds to a "need." For example, a connection is established via the emergency call module when a specific operating state is reached.When the emergency call module is used in an alarm system, a mobile phone connection to a call subscriber is established according to one design when an alarm is triggered.
[0033] If an emergency call is established with a recipient offering so-called early media content, one option is to suppress this content. Particularly in panic situations where an emergency call is made, it is of little help if the caller is forwarded to voicemail. Furthermore, automated telephone systems that require specific questions and demand information from the caller before the actual connection is established are generally unhelpful and / or potentially unusable. Often, the caller is trapped in an elevator, for example, and has no way of using an automated telephone system. Moreover, very few people in distress have the patience to effectively use an automated system.Thus, it is specifically intended that a direct connection to the call recipient, bypassing the early media content, is enforced via the emergency call SIM card.
[0034] Another configuration provides that if, for example, routing the call past early-media content is not possible, or if the called party does not answer or accept the call, the call is forwarded to another number. For instance, after a defined period without an answer from the called party, a new call is placed, preferably to another number stored in the emergency call module's phonebook. Preferably, all numbers in the phonebook are called sequentially until a call is received from the called party. In another variant, two or more numbers stored in the phonebook are called simultaneously; preferably, all stored numbers are called at once.
[0035] Another variant proposes that authentication of the call recipient be carried out, particularly via multi-frequency dialing. This allows, for example, a control center to immediately identify and locate the person seeking help or the emergency call module being used. A further embodiment also envisages authentication via a data stream, with the data preferably being transmitted in parallel to any voice data being transmitted.
[0036] In another variation of the procedure, a transmission protocol is selected from a number of available protocols, which the emergency call module uses to communicate with the target subscriber via the emergency call SIM card. Specifically, the target subscriber assigns the transmission protocol to be used to the emergency call module or the emergency call SIM card. Depending on the data or voice transmission protocol supported by the emergency call module, the emergency call SIM card, and / or the target subscriber, a suitable transmission protocol is assigned to the emergency call module. In particular, the authentication of the emergency call module by the target subscriber enables the appropriate selection from a number of protocols.The system allows for flexible use of the emergency call module with various control centers that support different protocols, as well as with different alarm systems or emergency call systems that support different protocols, particularly those with varying speeds. One configuration also provides for the emergency call module or emergency call SIM card to automatically select the transmission protocol used. This selection is based primarily on the detected protocols of the target subscriber or the emergency call system with which the emergency call module is connected.
[0037] The emergency call module performs regular checks of its own parameters and / or those of connected components. This includes monitoring the battery level of a power supply and / or the mobile network signal. In a further configuration, the module checks the priority level of the emergency SIM card on the mobile network. Another configuration includes checking the status of the uninterruptible power supply (UPS), specifically the network connection and battery charge level. The module also checks the connection quality with the mobile network, specifically the signal strength. In particular, it checks the necessary transmission power required to establish a connection with a mobile base station.The higher the transmission power required to establish a connection to a mobile network base station, the lower the connection quality. If the test of at least one defined parameter yields a negative result, a status message is sent in one version to at least one address stored in the phone number memory. A negative result here is defined as exceeding or falling below a predefined value for a parameter, for example, if this impairs or disrupts the function of the emergency call module, or if a malfunction is imminent. Preferably, the result is predefined.
[0038] In one configuration, a status message is sent when, for example, the power supply is no longer guaranteed, the battery charge level has fallen below a certain value (preferably half or one-third charge), or the battery is defective or empty. Furthermore, a status message can be sent to at least one address stored in the phone number memory if, for example, the connection quality to the mobile network weakens or is lost. In particular, if the connection to the mobile network is lost, a redundant telecommunications connection is necessary to send the status message. For example, an additional connection to a wired network is used. This connection is, for example, implemented via a DECT connection.In a further configuration, a status message is sent at regular intervals to at least one address stored in the phone number memory. The status message can contain all, some, or one of the monitored parameters; in particular, the regular status messages can be used to check whether a mobile network connection still exists. If no status message is received by, for example, a control center for a certain period, the control center can check whether the emergency call module is still operational. For this purpose, the control center can, for example, call the emergency call module. During a call, a message previously stored on the emergency call module is transmitted to the caller. Furthermore, it is possible for the parameters to be transmitted to the caller via a data connection or an automated message.Status updates can be sent, for example, via an automated message to a control center or to any recipient. One option is to send a short message via SMS. Another option is to send a status update via email.
[0039] Another option involves activating an alarm output of the emergency call module, or sending a signal, if a test of at least one defined parameter fails. For example, when the emergency call module is used in an elevator system, the connection to the mobile network is checked during regular parameter testing. If an interruption of the mobile network connection is detected, preferably for a certain period, the alarm output of the emergency call module is activated. In this configuration, the emergency call module can then be connected to the elevator system's control unit. In one example, the elevator system's control unit is programmed so that if the alarm output of the emergency call module sends a signal, the elevator is shut down.For example, the elevator system moves to a defined position; for instance, a car is moved to the nearest floor, the doors are opened, and then any further action with the car is prevented. The car can no longer be moved. In one configuration, the alarm output is deactivated as soon as a mobile network connection is re-established, allowing the elevator to return to normal operation. Specifically, the elevator is not only shut down due to a lack of network connection, but also when other parameters dictate it, such as a power supply failure to the emergency call module or a battery level falling below a certain threshold. Furthermore, the alarm output is continuously connected to a signal, and an emergency function of a connected component is only activated when the signal at the alarm output is deactivated.The alarm output of the emergency call module can also be useful in alarm systems. Certain processes can be carried out via the alarm output. For example, one embodiment provides for the alarm output to activate a siren. Another embodiment provides for the alarm output to switch a power supply, for example, for a camera or other surveillance device. A further embodiment provides for the alarm output to switch, for example, a DECT module, which, for instance, acts as a redundant system in the event of a loss of mobile network connection. It should be noted in this context that, when using the DECT module, both the emergency call module and the DECT receiver, which is connected to the wired telephone network, are preferably connected to an uninterruptible power supply.
[0040] Further advantageous embodiments are shown in the following drawings. However, the developments shown there are not to be interpreted as limiting; rather, the features described therein can be combined with each other and with the features described above to form further embodiments. Furthermore, it should be noted that the reference numerals given in the figure descriptions do not limit the scope of protection of the present invention, but merely refer to the exemplary embodiments shown in the figures. Identical parts or parts with the same function are referred to by the same reference numerals in the following. The figures show: Fig. 1 an emergency call module and a connection to a control center in schematic view; Fig. 2. an elevator system with an emergency call module; and Fig. 3. An alarm system with an emergency call module.
[0041] Fig. Figure 1 shows an emergency call module 1 with an emergency call SIM card 2, an uninterruptible power supply 3, wherein the uninterruptible power supply 3 has a, in particular, wired network connection 4 and a battery 5. The emergency call module 1 is connected to a mobile communication antenna 6, which is located in the Fig. In the embodiment shown in Figure 1, the emergency call module 1 is connected to the mobile network via a telecommunications interface 7. The emergency call module 1 also has a first data interface 8. A communication device 9 is connected to the data interface 8. The communication device 9 is, in particular, a telephone. Preferably, the first data interface 8 allows the connection of an analog device, preferably an analog telephone. The emergency call module 1 also has an input interface 10, to which an emergency call button 11 is connected. When the emergency call button is pressed, the emergency call module 1 establishes a connection to the mobile network.
[0042] Using the emergency SIM card 2, a high priority is assigned to a mobile connection. Preferably, the mobile connection receives an above-average priority within the mobile network, for example, a priority level below 4 in an eMLPP-enabled mobile network. The phone number is then dialed automatically. This uses a number stored in the emergency SIM card's phone number memory.
[0043] Furthermore, the emergency call module 1 has a second data interface 13, to which, as an example, a camera 14 is connected. This camera can be in continuous operation or, for example, switched on when a connection to a telephone subscriber is established. Preferably, the camera 14 can be switched on, controlled, and its data accessed by a telephone subscriber 27, for example, via the emergency call module 1.
[0044] The emergency call module also has an alarm output 15, which in this configuration is coupled to a signal transmitter 16. Furthermore, the emergency call module has a monitoring unit 17. The operating status can be accessed via indicator lights 18 and / or a monitor 19. For programming the emergency call module 1 and the emergency call SIM card 2 inserted into the emergency call module, the emergency call module 1 has a programming interface 20. This interface can be connected, for example, to a computer 21, which can then be used to perform the programming. It is also provided that programming can be carried out via a mobile network connection. In one embodiment, programming is performed, for example, by means of at least one SMS message.
[0045] Furthermore, the in Fig. The emergency call module 1 shown incorporates a DECT module 22. This is used particularly when a mobile network connection has failed or is too weak. The DECT module is also powered via the uninterruptible power supply 3. Furthermore, a Fig. One DECT receiver (not shown) connected to a wired network, also powered by an uninterruptible power supply. This also enables, in particular, a connection to an ISDN or Voice-over-IP network.
[0046] Fig. Figure 1 further shows a base station for mobile networks 23. This station directly serves at least one cell. An incoming call from the emergency call module 1 is forwarded by the mobile base station 23, for example, to a call destination 27. The signal can also be forwarded, for example, to a control center 24. The control center preferably monitors several locations, each of which has an emergency call module or wired emergency call devices. The control center 24 has, in particular, a computer 25 and at least one telephone 26. The emergency call module can, for example, send messages that can also be retrieved via the computer 25. For example, the emergency call module 1 sends an email via the internet. For this purpose, the emergency call module 1, and in particular the emergency call SIM card 2, is designed to allow a data packet connection via the mobile network.As a rule, in the event of an emergency, the alarm button 11 is pressed and a voice communication connection is established via the communication device 9 to the telephone 26 of a call target subscriber 27 or a control center 24.
[0047] Fig. Figure 2 shows the use of an emergency call module 1 in an elevator system 28. Preferably, the emergency call module is installed in a car 29 of the elevator system 28. A telecommunications device 9 and an emergency call button 11 are located inside the car, so that a person 30, for example, trapped in the car, can contact, for example, a control center 24 via the communication device 9 after pressing the emergency call button 11. Since a mobile communication connection within an elevator shaft is usually weak or even impossible, a detachable mobile communication antenna 6 is provided, which is attached to an exterior wall of the building or the elevator system. In particular, the mobile communication antenna 6 is connected to the emergency call module 1 by a cable.
[0048] Fig. Figure 3 shows the emergency call module 1 in conjunction with an alarm system 32. In the event of an alarm-triggering incident 31, for example, an emergency button 11 is activated, which is located in the Fig. In the embodiment shown in Figure 3, a glass breakage sensor is used. Furthermore, the alarm system can be connected to the input interface 10 of the emergency call module 1, so that an emergency call signal is triggered by the alarm system when an incident 31 is detected. When an emergency call signal is triggered, an automatic message can, for example, be sent to a control center 24. It is also possible, for example, to listen in to the monitored room via the established mobile network connection. Additionally, a camera 14 is connected to the alarm system 32 or to the emergency call module 1. This allows, for example, video surveillance by the control center 24 via data transmission over the mobile network.
