Abstract
ABSTRACT OF THE DISCLOSURE
An intelligent emergency call system (ESYS) is proposed.
This system utilizes wire-bound (EW) and wireless emergency call transmission apparatuses (ER1, ER2) that each include a card reader (CI) which reads an identification number as well as personal and medical emergency data (EDAT) from a patient chip card (CC). The read emergency data are transmitted in an emergency call message (EMES), e.g. via a telephone network (TN), an energy-supply network (PN) or a mobile radio network (RN), to at least one emergency call receiver apparatus (R) and/or a rescue relay center (EC). Appropriate rescue efforts can thus be initiated.
The wireless emergency call transmission apparatus can be configured as an individual unit or as an add-on module for a radio device.
The emergency call system is suited for both personal protection as well as for protection of objects (buildings, transport, etc.).

Description
EMERGENCY CALL SYSTEM
Emergency call systems are known in which emergency calls can be placed by means of wireless or wire-bound emergency call transmlssion apparatuses.
An emergency call system is known from DE 4,130,647 .Al in which an emergency call signal is transmitted from a portable radio transmitter to a base unit of a cordless telephone. The emergency call signal contains an emergency call code which is decoded in the receiver of the base unit.
This emergency call code indicates a telephone number that is stored in the base unit. A telephone-dialing apparatus inside the base unit controls a dialing procedure for a telephone connection with an individual who can be reached at this telephone number. This individual is only informed (e.g. by way of an automated voice message) that an emergency situation is occurring.
A public telephone network is known from DE 3,410,619.Al in which text messages are stored, so that speech-impaired individuals, for one, can request help in an emergency. For this purpose, every publia telephone station is equipped with a text aard-reading apparatus, which reads address and text data from a portable text card inserted into the text card-reading apparatus in an emergency. The public telephone station utilizes automatic dialing apparatuses that dial a specific receiving station according to the address data, and transmit the text data to this station.
A wire-bound emergency call system equipped with IS~N
terminals and chip card readers is known from "Patent Abstracts of Japan, JP 2-22 69 51 A, E-1006, Nov. 27, 1990, Vol. 14, No. 537." A connection is made to an emergency call center (e.g. police, fire department, hospital) upon insertion of chip card on which emergency call information is stored. Afterward, the emergency call information and the identification of the ISDN terminal (user-user information) are connected to one another in an editor and transmitted to the emergency call center.
A further emergency call system is described in, for example, the article "Notruftelefon" [Emergency Call Telephone], by A. Kailling, Instructional Pamphlets of the German Federal Post Office, pp. 3 - 14, 1st Ed., 35/1982. In this article the so-called emergency call system 73 is described, in which emergency calls are transmitted by way of the public telephone network of the German Federal Post Office. This emergency call system is designed for personal protection and protection of property within a limited area of protection, and only permits local placement of an emergenoy call. The emergency call system is set up within the local networks so that the police or fire department can 5 be called upon in an emergency. It is also realized as an 21~011 emergency call box system for highways. The emergency calls are transmitted to a so-called emergency assistance request station that initiates and coordinates rescue action. The emergency call itself, i.e. the trigger of an alarm, can be followed by the transmission by telephone of a report of an emergency so that concerted rescue action can be initiated.
Further emergency call systems are known in which emergency calls can be placed via radio, i.e. locally. An emergency call system of this type is described, for example, in the article "Autonotfunk, ein Funknotmeldesystem fur Verkehrsteilnehmer" [Emergency Automobile Radio, a Radio Emergency Report System for Drivers] by A. Simianer, NTG
Technlcal Reports, "8ewegliche Funkdienste" [Mobile Radio Services], Vol. 61, pp. 148 - 152, VDE Publishing Co., 8erlin, 1977. This so-called "emergency automobile radio system" comprises wireless emergency call transmission apparatuses that are installed into motor vehicles. It is possible to transmit an emergency call message that includes "the vehicle identification (number on the vehicle registration) and the nature of the crisis (emergency, accldent)"; lt 18 also pos~ible to hold a "controlled, two-way conver8ation" with the emergency call center (rescue relay center). The motor vehicle can be located by means of radio direation finding.
212~0~1 Furthermore, radio systems are known in which the radio devices and radio stations are technologically equipped for emergency call service. Examples of such radio systems are the "GSM" (Global System for Mobile Communications) cellular mobile radio system and the "Chekker" bundled radio system, as described in the book Mobilfunk [Mobile Radio] by J. Kedaj and G. Hentschel, 1st Ed., Chapters 4 - 6, Neue Mediengesellschaft Publishing Co., Ulm, 1991. In these two radio systems, the subscriber's respective radio device also serves as an emergency call radio apparatus. This apparatus triggers an alarm by way of the organization channel, and forces a subsequent allocation of a voice channel, by way of which a report of an emergency can be made to the alarm center.
The known emergency call systems are tailored for a specific area of protection (highways, buildings, radio range ... ) and specific circles of people (automobile drivers, mobile radio subscribers ... ).
With the known emergency call systems, information about the persons affected by the emergency must be imparted orally to the alarm center. This is not po8sible in every emergency situation, particularly when no assistants are in the area and the affected person is seriously in~ured. Also, people who have problems speaking (e.g. foreigners or the . ~* .
,. . .
' ~ ' speech-impaired) cannot fully utilize these conventional emergency call systems.
It is an object of the invention to design an emergency call system that permits everyone to transmit an emergency call with a report of an emergency and request speciflc assistance simply and quickly.
The object is attained by an emergency call system having the features of claims 1 and 2.
Furthermore, apparatuses for such an emergency call system are to be designed.
These ob~ects are attained by apparatuses having the features of claims 4, 7, 10 or 11.
Advantageous modifications of the invention are to be taken from the dependent claims.
Accordingly, it is particularly advantageous to set up the emergency call system in existing wire-bound transmission networks, for example the telephone network and the 8treetlight network. The utilization of this diversified lnfrastructure permits the emergency call system to be constructed and expanded cost-effectively.
Moreover, it 18 particularly advantageous to conflgure the emergency call system such that it uses existing service radio networks or mobile radio networks. ~y means of the wireless emergency call transmission apparatus, which 5 transmits an emergency call message on a corresponding 212~011 service or mobile radio channel, assistance can be requested at any time within the entire radio range.
It is also particularly advantageous to equip -the emergency call transmission apparatus with the type of card reader that can read a so-called patient chip card.
Important medical patient data can thus be read and integrated into the emergency call message.
Two embodiments of the invention are described below with reference to four drawing figures.

Emergency call transmission apparatuses EW and ER1 each include a card reader that reads, from a memory card CC, emergency data EDAT to be transmitted.
Emergency call system ESYS includes three emergency call recelver apparatuses R that trigger an alarm function, for example a light signal L, an acoustic signal A or video monitoring system V in the event that an emergency call mes~age EMES is received that includes a corresponding identlfication. One of the emergency call receiving ;
apparatuses R i8 realized in a radio switching center MSC of mobile radio network RN, another in a private branch exchange of telephone network TN. These emergency call receiving apparatuses further aonduot emergency data EDAT of emergency aall message EMES to alarm center EC in case the identiflaation indicates, for example, a request for medical as8istance.

First, the three above-named networks TN, PN and RN that constitute the transmission network of emergency call system ESYS are described.
Mobile radio network RN, for example, is designed according to the GSM standard. It includes a plurality of stationary radio stations BS, a radio switching center MSC
connected therewith and a service and assessment location OMC
connected therewith.
A per~on within the radio link hop range of one of 8tationary radio stations BS can place a wireless emergency call at any tlme by means of the wireless emergency call transmission apparatus ERl, hereinafter referred to as emergency call radio apparatus. ~he emergency call radio apparatus can be configured as, for example, a compact data radlo devlce. It is likewise possible to integrate the radio apparatus into a mobile radio apparatus (mobile station, hand-held) or into a stationary radio telephone (fixed, wlreless telephone). Uslng its card reader, emergency call apparatus ERl reads the emergency data from memory card CC, which has been inserted by the user. This memory card CC is, for example, the so-called patient chip card of the user or 5 that of another person requiring assistance.

Mobile radio network RN, for example, is designed according to the GSM standard. It includes a plurality of stationary radio stations BS, a radio switching center MSC

connected therewith.
A per~on within the radio link hop range of one of 8tationary radio stations BS can place a wireless emergency call at any tlme by means of the wireless emergency call transmission apparatus ERl, hereinafter referred to as emergency call radio apparatus. ~he emergency call radio apparatus can be configured as, for example, a compact data radlo devlce.

In an emergency si~uation, the emergency data, which lnclude personal and medical data, are transmitted multiple times in an emergency call message EMES on a mobile radio channel. On the receiving side, the emergency call message signalizes to radio sw~tching center MSC, which is equipped in this case with one of the emergency call receiver apparatuses R. Inside this emergency call receiver apparatus, emergency call message EMES is evaluated by decoding and deciphering stages in order to trigger the alarm functions required for the reported emergency.
In this example, an emergency call that indicates a motor vehicle accident is transmitted. The transmission of the emergency call can be triggered by an acceleration meter (crash sensor) in the vehicle. The approximate position of the polnt of accident is determined by the radio link hop range, that is, by the identification of the corresponding stationary radio stations. Emergency call receiver apparatus R triggers a visual alarm L in service and evaluation center OMC, and transmits emergency data EDAT to alarm center EC by way of the telephone network connected to radio switching center MSC. This center can initiate efficient action with the aid of the emergency data. Furthermore, service and evaluation center OMC can initiate the transmission of a brief message (short message broadcast) with warning :: : ~ :

In the emergency call system ESYS shown, the above-named telephone network TN is used to transmit emergency call messages EMES. This telephone network is, for example, a public, ISDN-capable telephone network equipped with emergency call transmission apparatuses EW, which transmit emergency call messages on the data channel (D channel) according to ISDN protocols.
By way of example, two emergency call transmission apparatuses EW are shown here, of which one is integrated into a table telephone unit, and the other is integrated into the base unlt of a cordless telephone CT. In future telecommunicatlon networks designed according to the UPT
concept (Unlversal Personal Telecommunications, see the article "Dritte Generation der Mobilkommunikation [The Third Generation of Mobile Communication] by Dr. of Engineering H.
Armbruster, 1992, Telecom Report 15, part 2, Siemens AG, Munich, Germany), card readers will already be built into subscribers' terminals, and can then be used to read emergency aall data.
An emergency call is inltiated by the insertion of the patient chip card. It is also conceivable to initiate the emergency call by operating the selection keyboard, with a plurality of key combinations being available. Each key 212~011 combination corresponds to a logical switching means that effects the linkage of emergency call message EMES with a predetermined identification. The respective identification determines which alarm function, here for example alarm A, will be triggered by one of the emergency call receiver ~ ;
apparatuses.
In this embodiment, for the purpose of triggering an acoustical alarm A in the vicinity in an emergency, an emergency call receiver apparatus R is installed in private branch exchange PABX, to which the two telephones are connected. The emergency call is conducted by way of the telephone network to the closest local switching center, to -which an alarm center EC is connected. The alarm center, whlch 18, for example, the local rescue relay center, receives emergency call data EDAT in order to request specific emergency services (doctor on emergency call, fire department) and to provide them with detailed information.
Emergency call system ESYS permits everyone to obtain assistance quickly and efficiently. Through the use of the public telephone network, the emergency call system ESYS may be realized cost-effectively and over large areas.
The emergency call system ESYS shown ln Flgure 1 further comprl8es an energy-supply network, here for example a streetllght network PN, by way of which emergency call me88ages are transmitted by means of pulse-code modulation.
Wire~bound emergency call transmission apparatuses EW are connected to streetlight network PN, which is connected to telephone network TN by way of an NF transmitter. These apparatuses are, for example, conspicuously-marked emergency telephones installed at locations that represent particularly dangerous areas (train stations, airports, parking garages, street crossings ...). An emergency call using an emergency call message is placed when a memory card CC is inserted into one of the emergency telephones. In addition to emergency data EDAT, the emergency call message includes the location identiflcation of the emergency telephone EW used. The emergency call is conducted to telephone network TN with the ald of the NF transmltter to be transmitted to the alarm center.
Streetlight network PN includes emergency call receiver apparatuses R, which are installed at ~elected locations in order to trigger predetermined alarm functions there. In this example, one of the emergency call receiver apparatuses R, to which a video camera V is connected, is installed in the immedlate vicinity of a building (bank, embassy) to be observed. When an emergency call is initiated by one of the nearest emergenay call receiver apparatuses, this emergency call receiver apparatus activates video camera V. This camera in turn transmits image data to the alarm center at a 5 transmisslon speed of, for example, 64 Kbit. There, continuous images of the image data are reproduced to bedisplayed on the monitor.
The emergency call system ESYS shown in Figure 1 is an embodiment that indicates the multi-faceted application of the invention. Numerous configurations that have been optimized for specific requirements (transport monitoring, protection of ob~ects, works protection) are conceivable.
Embodiments of the wireless emergency call transmission apparatus are also described, and possible realizations of the transmission of the emergency call message are outline.
For example, the following descriptive section also applies for the above-mentioned, wire-bound emergency call tran8misslon apparatuses.
The wireless emergency call transmission apparatus ER1 shown in Figures 2a and 2b, hereinafter referred to emergency call radio apparatus, is configured as a portable device to be used in a TDMA (Time Division Multiple Access) mobile radlo network.
In Figure 2a, emergency call radio apparatus ERl comprlses a card reader CI, a signal-processing element BB
dl~posed downstream thereof, an HF transmisslon element TX
dlsposed downstream of signal-processing element BB, and an alarm switch SOS for closing the supply circuit.
Card reader CI accepts and reads a chip card CC, which 5 rontains a central computational unit CPU, a storage for constant values ROM, a working memory RAM and a data memoryEEPROM. The design and function of such a chip card is described in, for example, the article "Rechengenie in der Plastikkarte" [Computing Genius in the Plastic Card] by Dr.
T. Wille, published in the magazine "Funkschau" [Radio Show], 7th Ed., 1993, Franzis Publishing Co., Munich, and the article by H.P. Kistner, "Funkschau," 6th Ed., 1993, Franzis Publishing Co., Munich.
In this example the card reader is configured corresponding to the standard published in the ISO
(International Standards Organization) document # 7816-2;
1988 (E), Technical Committee ISO/TC 97, Information Processlng Systems, 5/15/88, 1st Ed. Because of this conflguratlon, so-called patient chip cards can be read as descrlbed in the above article by H.P. Kistner. These patlent chlp cards contaln personal and medical data pertalnlng to the cardholder.
The emergency radio apparatus therefore has access to data such as the name, address and insurance number, the blood type and age of the cardholder. In an emergency, these data are avallable as so-called emergency data that can be transmltted ln an emergency call message.
Slgnal-processlng stage BB, whlch comprises a digltal slgnal processor DSP and two dlgital-analog converters, 5 serves to prepare the emergency call message and produce an 212~011 analog baseband signal. Signal-processing element BB is connected to card reader CI by way of a PCM bus and, using the read emergency data, generates the quadrature components of a burst-modulated baseband signal.
In the HF transmission element TX, this baseband signal is converted into the HF position, amplified and emitted via an antenna.
The current supply of the above components is closed by way of alarm switch SOS. If the user of emergency call radio apparatus ERl has inserted his chip card into card reader CC, a radio emergency call containing important emergency data can be transmitted at any time by operating alarm switch SOS.
Because the lllustrated emergency call radio apparatus comprises components known to a person skilled in the art, a detailed description is not provided here. The emergency call radio apparatus ERl shown in Figures 2a and 2b is suited for use in a TDMA mobile radio system, particularly the GSM.
Signal-processing element BB, HF transmission element TX and the devlce control, not shown, correspond to the components of a GSM moblle station, as described in, for example, the artlcle "Archltektur elnes Mobllfunkgerates f~r das Netz D"
~Archltecture of a Moblle Radio device for Network D] by P.
Schoffel et al in the magazine "Philips Innovation 1/91."
Flgure 2b shows an embodiment of emergency call radio apparatus ER1 that is particularly practical to carry. In .
2~25011 this embodiment the above-named components are installed in a portable housing PH. The portable housing is provided with a carrying frame CB, into which an antenna A is integrated.
Emergency call radio apparatus ER1 can thus be carried close to the user's body without antenna A representing a spatial obstacle or posing a threat of injury. Moreover, the operating button of alarm switch SOS is imbedded in a housing depression in order to prevent false alarms.
The illustrated emergency call radio apparatus ER1 includes those components required for reading emergency call data EDAT and for transmitting an emergency call message EMES. Further components that are not required for radio transmission of emergency call message EMES, for instance an audio element and an HF receiver element, were omitted. This enables emergency call radio apparatus ERl to be configured as a very compact, portable instrument. Moreover, within the mobile radlo network, no continuous determination of the location (location update) is required, as in a two-way radio apparatus. When personal patient chip card CC is inserted, the instrument is on alarm stand-by. In this state, no 8upply current flows, 80 the supply battery remains unloaded.
In an emergency, an identification number PIN is first read by means of operating alarm switch SOS; this PIN serves to ldentify and verify the authenticity of the person in the emergency situation. The reading of the personal emergency . . . ! ' : , ': . ~ ` .......
212~011 data EDAT, such as name, insurance number, blood type, ageand indications of high-risk (hemophiliac? Epilepsy?
Diabetes?) commences. Access to chip card CC is gained according to the standard described in IS0 document # 7816-3:
1988 (E).
The read emergency data are inserted into emergency call message EMES. This emergency call message is created like, for example, a TDMA access time slot (access burst) according to the GSM standard. It includes a 41-bit sequence Sync for recelver-side synchronization, and a 36-bit sequence for transmitting information data which indicate that an emergency call is being transmitted, and encompass emergency data EDAT. Emergency call message EMES is transmitted multlple times, e.g. 20 times, by way of an organizational channel.
Through the non-verbal transmission of information, a rescue relay center then obtains important emergency data in case no one at the point of the accident is able to speak.
The locallzation of emergency call radio apparatus ERl is effected, for example, by measuring the receiving field intensity ln the statlonary radio statlons of the mobile radio network, that ls, by means of radio cell allocation.
Cross-bearlng by means of direction-finders is also concelvable.
The above-described example relates to an emergency call radio apparatus for people located in the supply region of a GSM network. It is also conceivable to use the emergency call radio apparatus for protection of objects, for instance warehouse monitoring, vehicle theft insurance and transportation monitoring. Chip cards used for these purposes would provide detailed identification of the stored goods, the vehicle, or transported item, respectively. It is also conceivable to configure the emergency call radio apparatus to include a card reader or reading apparatus for magnetic strlps or punched cards, or to accommodate plug-in chips.
The u8e of the emergency call radio apparatus is not limlted to mobile radio networks. The invention can be configured for arbitrary radio systems in which data can be transmitted. For example, an embodiment for use in a service radio system is conceivable. In this instance, personnel in partlcular danger would use portable emergency call radio apparatuses, for example integrated into tool bags. The chip card contains, among others, data that provide information on hazardous substances present in the workplace.
The emergency call radio apparatus of the invention can furthermore be integrated into a radio device, particularly into a mobile radio device that already has a card reader. A
5 conventional radio device can thus be expanded to a radio 212~011 apparatus that has an intelligent emergency call function.In accordance with the invention, for example a GSM mobile radio device is equipped with an intelligent emergency call function in that the program for controlling the instrument (firmware) initiates the reading of emergency data from the patient chip card in the card reader, the creation of the emergency call message in the signal~processing element and transmission by way of a mobile radio channel. This mobile radio channel is, for example, a signalization channel for short message transmission (service).
A second embodiment according to Figure 3 is described below.
Figure 3 illustrates an emergency call radio apparatus ER2 comprising a card reader CI, a downstream selection stage having four switches Sl through S4, a downstream signal-processing element BB, a downstream HF transmission element, a downstream duplexer that has a transmitter/receiver antenna and a satellite radio receiver SAT connected on the receiver slde and whose data output is connected to signzl-processing element BB.
In comparison to the above-described embodiment acoording to Figure 2, the second embodiment according to Figure 3 includes the selection stage and the satellite radio receiver, by means of which a predetermined identification 11 :: . . ' : ' ... 14, or determined position data POS are added to the emergency call message EMES to be transmitted.
The selection stage comprises four switches S1 ... S4 that are respectlvely assigned a specific alarm category.
Possible alarm categories include:
1.) "Full alarm with ambulance"
2.) "Full alarm without ambulance"
In an emergency si~uation, the emergency data, which lnclude personal and medical data, are transmitted multiple times in an emergency call message EMES on a mobile radio channel. On the receiving side, the emergency call message signalizes to radio sw~tching center MSC, which is equipped in this case with one of the emergency call receiver apparatuses R. Inside this emergency call receiver apparatus, emergency call message EMES is evaluated by decoding and deciphering stages in order to trigger the alarm functions required for the reported emergency.
In this example, an emergency call that indicates a motor vehicle accident is transmitted. The transmission of the emergency call can be triggered by an acceleration meter (crash sensor) in the vehicle. The approximate position of the polnt of accident is determined by the radio link hop range, that is, by the identification of the corresponding stationary radio stations. Emergency call receiver apparatus R triggers a visual alarm L in service and evaluation center OMC, and transmits emergency data EDAT to alarm center EC by way of the telephone network connected to radio switching center MSC. This center can initiate efficient action with the aid of the emergency data. Furthermore, service and evaluation center OMC can initiate the transmission of a brief message (short message broadcast) with warning :: : ~ :

- 2~25011 indications to all mobile radio subscribers located in the vicinity of the scene of the accident.
In the emergency call system ESYS shown, the above-named telephone network TN is used to transmit emergency call messages EMES. This telephone network is, for example, a public, ISDN-capable telephone network equipped with emergency call transmission apparatuses EW, which transmit emergency call messages on the data channel (D channel) according to ISDN protocols.
By way of example, two emergency call transmission apparatuses EW are shown here, of which one is integrated into a table telephone unit, and the other is integrated into the base unlt of a cordless telephone CT. In future telecommunicatlon networks designed according to the UPT
concept (Unlversal Personal Telecommunications, see the article "Dritte Generation der Mobilkommunikation [The Third Generation of Mobile Communication] by Dr. of Engineering H.
Armbruster, 1992, Telecom Report 15, part 2, Siemens AG, Munich, Germany), card readers will already be built into subscribers' terminals, and can then be used to read emergency aall data.
An emergency call is inltiated by the insertion of the patient chip card. It is also conceivable to initiate the emergency call by operating the selection keyboard, with a plurality of key combinations being available. Each key 212~011 combination corresponds to a logical switching means that effects the linkage of emergency call message EMES with a predetermined identification. The respective identification determines which alarm function, here for example alarm A, will be triggered by one of the emergency call receiver ~ ;
apparatuses.
In this embodiment, for the purpose of triggering an acoustical alarm A in the vicinity in an emergency, an emergency call receiver apparatus R is installed in private branch exchange PABX, to which the two telephones are connected. The emergency call is conducted by way of the telephone network to the closest local switching center, to -which an alarm center EC is connected. The alarm center, whlch 18, for example, the local rescue relay center, receives emergency call data EDAT in order to request specific emergency services (doctor on emergency call, fire department) and to provide them with detailed information.
Emergency call system ESYS permits everyone to obtain assistance quickly and efficiently. Through the use of the public telephone network, the emergency call system ESYS may be realized cost-effectively and over large areas.
The emergency call system ESYS shown ln Flgure 1 further comprl8es an energy-supply network, here for example a streetllght network PN, by way of which emergency call me88ages are transmitted by means of pulse-code modulation.
Wire~bound emergency call transmission apparatuses EW are connected to streetlight network PN, which is connected to telephone network TN by way of an NF transmitter. These apparatuses are, for example, conspicuously-marked emergency telephones installed at locations that represent particularly dangerous areas (train stations, airports, parking garages, street crossings ...). An emergency call using an emergency call message is placed when a memory card CC is inserted into one of the emergency telephones. In addition to emergency data EDAT, the emergency call message includes the location identiflcation of the emergency telephone EW used. The emergency call is conducted to telephone network TN with the ald of the NF transmltter to be transmitted to the alarm center.
Streetlight network PN includes emergency call receiver apparatuses R, which are installed at ~elected locations in order to trigger predetermined alarm functions there. In this example, one of the emergency call receiver apparatuses R, to which a video camera V is connected, is installed in the immedlate vicinity of a building (bank, embassy) to be observed. When an emergency call is initiated by one of the nearest emergenay call receiver apparatuses, this emergency call receiver apparatus activates video camera V. This camera in turn transmits image data to the alarm center at a 5 transmisslon speed of, for example, 64 Kbit. There, continuous images of the image data are reproduced to bedisplayed on the monitor.
The emergency call system ESYS shown in Figure 1 is an embodiment that indicates the multi-faceted application of the invention. Numerous configurations that have been optimized for specific requirements (transport monitoring, protection of ob~ects, works protection) are conceivable.
Embodiments of the wireless emergency call transmission apparatus are also described, and possible realizations of the transmission of the emergency call message are outline.
For example, the following descriptive section also applies for the above-mentioned, wire-bound emergency call tran8misslon apparatuses.
The wireless emergency call transmission apparatus ER1 shown in Figures 2a and 2b, hereinafter referred to emergency call radio apparatus, is configured as a portable device to be used in a TDMA (Time Division Multiple Access) mobile radlo network.
In Figure 2a, emergency call radio apparatus ERl comprlses a card reader CI, a signal-processing element BB
dl~posed downstream thereof, an HF transmisslon element TX
dlsposed downstream of signal-processing element BB, and an alarm switch SOS for closing the supply circuit.
Card reader CI accepts and reads a chip card CC, which 5 rontains a central computational unit CPU, a storage for constant values ROM, a working memory RAM and a data memoryEEPROM. The design and function of such a chip card is described in, for example, the article "Rechengenie in der Plastikkarte" [Computing Genius in the Plastic Card] by Dr.
T. Wille, published in the magazine "Funkschau" [Radio Show], 7th Ed., 1993, Franzis Publishing Co., Munich, and the article by H.P. Kistner, "Funkschau," 6th Ed., 1993, Franzis Publishing Co., Munich.
In this example the card reader is configured corresponding to the standard published in the ISO
(International Standards Organization) document # 7816-2;
1988 (E), Technical Committee ISO/TC 97, Information Processlng Systems, 5/15/88, 1st Ed. Because of this conflguratlon, so-called patient chip cards can be read as descrlbed in the above article by H.P. Kistner. These patlent chlp cards contaln personal and medical data pertalnlng to the cardholder.
The emergency radio apparatus therefore has access to data such as the name, address and insurance number, the blood type and age of the cardholder. In an emergency, these data are avallable as so-called emergency data that can be transmltted ln an emergency call message.
Slgnal-processlng stage BB, whlch comprises a digltal slgnal processor DSP and two dlgital-analog converters, 5 serves to prepare the emergency call message and produce an 212~011 analog baseband signal. Signal-processing element BB is connected to card reader CI by way of a PCM bus and, using the read emergency data, generates the quadrature components of a burst-modulated baseband signal.
In the HF transmission element TX, this baseband signal is converted into the HF position, amplified and emitted via an antenna.
The current supply of the above components is closed by way of alarm switch SOS. If the user of emergency call radio apparatus ERl has inserted his chip card into card reader CC, a radio emergency call containing important emergency data can be transmitted at any time by operating alarm switch SOS.
Because the lllustrated emergency call radio apparatus comprises components known to a person skilled in the art, a detailed description is not provided here. The emergency call radio apparatus ERl shown in Figures 2a and 2b is suited for use in a TDMA mobile radio system, particularly the GSM.
Signal-processing element BB, HF transmission element TX and the devlce control, not shown, correspond to the components of a GSM moblle station, as described in, for example, the artlcle "Archltektur elnes Mobllfunkgerates f~r das Netz D"
~Archltecture of a Moblle Radio device for Network D] by P.
Schoffel et al in the magazine "Philips Innovation 1/91."

A second embodiment according to Figure 3 is described below.
Figure 3 illustrates an emergency call radio apparatus ER2 comprising a card reader CI, a downstream selection stage having four switches Sl through S4, a downstream signal-processing element BB, a downstream HF transmission element, a downstream duplexer that has a transmitter/receiver antenna and a satellite radio receiver SAT connected on the receiver slde and whose data output is connected to signzl-processing element BB.
In comparison to the above-described embodiment acoording to Figure 2, the second embodiment according to Figure 3 includes the selection stage and the satellite radio receiver, by means of which a predetermined identification 11 :: . . ' : ' ... 14, or determined position data POS are added to the emergency call message EMES to be transmitted.
The selection stage comprises four switches S1 ... S4 that are respectlvely assigned a specific alarm category.
Possible alarm categories include:
1.) "Full alarm with ambulance"
2.) "Full alarm without ambulance"
3.) "Silent alarm with ambulance"
4.) "Silent alarm without ambulance"
"Full alarm" means that the alerted emergency crews (police, fire department ... ) use acoustical and visual warning signals (sirens or blue light) when arriving at the scene of the emergency. In a "silent alarm," these warning signals are not to be used at the scene of the emergency.
This is advantageous when, for example, the emergency has been caused by persons using violence who should not be warned (robbery, rape, kidnaping ... ). Triggering a "silent alarm" can also be practical within the realm of ob~ect protection (intrusion, bank robbery). The triggering of one of the two above alarms can be used in con~unction with alerting the medical rescue service.
Swltches Sl ... S4 are connected to signal-processing element BB in such a manner that the operation of one of the switches effects the creation of emergency call message EMES

5 ocrresponding to the selected alarm category. In this 212~011 e~ample of Figure 3, the first alarm category "full alarmwith ambulance" is selected by operating the second switch S2. First the emergency call message acquires synchronization data Sync, an identification I2 that identifies the selected alarm category, and emergency data EDAT~ with the medical data required for this alarm category.
In an alarm without ambulance, only personal data EDAT- are used. Subsequently the emergency call message EMES to be sent acquires geographical position data POS, which are supplied by satellite radio receiver SAT and indicate the momentary location of emergency call radio apparatus ER2.
Afterward, emergency call message EMES is transmitted on a r~dio channel, e.g. on a bundled radio channel, by means of HF transmitter element TX.
Depending on the alarm category selected, emergency call message EMES is created with a specific identification and specific emergency data. On the one hand, this means that the safety and rescue services that are actually required are alerted, and on the other hand, only those required emergency data are transmitted to the rescue relay center that can be evaluated to a good end there.
As an alternative to the embodiment shown in Figure 3, an emergency call transmission apparatus is conceivable that utillzes a card reader into which the switches are installed 5 80 as to scan the contour of the memory card. Hence, the 21250~1 alarm category is determined by the inserted position of a memory card configured according to claim 12, for example having four different card contours.
The described emergency call radio apparatuses ER1 and ER2 are provided for mobile application of the invention within a radio network, particularly a cellular mobile radio network, and for this purpose can be configured as an individual unit or add-on module for a radio device, respectively. Embodiments are conceivable which permit intermittent stationary use, for instance as portable emergency call boxes for highway construction sites.
Embodiments of the wire-bound emergency call transmlsslon apparatuses EW can be derived from the above descrlption of wireless emergency call transmission apparatuses ERl and ER2, because the two emergency call transmission apparatuses are identical in operating principle. They differ only in their physical connection (wireless or wire-bound) to the transmission network of the emergency call system.
For example, wire-bound emergency call transmission apparatus EW includes a modulation stage that is lntegrated lnto signal-processing element ~ and, in accordance with the DTMF (Dual Tone Multifrequency) transmission method, feeds emergency call message EMES into an analogous telephone network for transmission.
` 212~0~1 The described embodiments of the emergency call system are particularly advantageous for personal protection.
