Definitions

  • the present invention is mainly related to a method and a device whereby commonly used radio (cellular) telephones facilitate various substantially physical types of services, and this is described, purely by way of example, for control of access, signalling, communication and e.g. entrance door lock opening for an entrance telephone system. However, also examples of other fields of use will be mentioned.
  • radio cellular
  • Entrance telephones used today are either arranged with installed fixed communication circuits ("local telephones") or connected to and switched through a public telephone network ("door telephones"). They exist basically due to a need for security and privacy - while still offering a sodal possibility - for inhabitants in areas which require locked entrances due to various threats and risks in mainly highly populated areas, but they also involve certain disadvantages.
  • WO 93 14571 A1 discloses establishment of a conventional call from a user's cellular telephone to a clearinghouse. After receipt of an incoming call, the clearinghouse uses a separate RF communication link from the clearinghouse to the locks controlled by the clearinghouse.
  • WO 94 01963 A1 discloses am access control system that uses transmitters which generate a dual tone (DTMF) modulated signal. A standard mobile telephone can thus be used to obtain access to controlled areas.
  • DTMF dual tone
  • the method disdosed in WO 94 01963 A1 is related to MFC-signalling and makes no use of the information obtainable during a "hand-shaking" procedure between a mobile radio telephone and adjacent conventional base station.
  • a further object of the present invention is to give mobile telephones existing "out there" desired possibility for control of visitors/entrance telephone properties for a building having the aforementioned installation.
  • scanners which today may for example include receiving capability for the entire GSM frequency range. Only the receiving capability of a scanner is required; since the communication properties of same according to the present invention are only utilized as a "passive" listener for data, same does not require analogue sound, nor transmitting possibility.
  • PCS 1900 "JAPAN PHS”, “DCS 1800”, “CT-2”, “CT-2-CALL”, “CT-3” and “DECT” and/or digital cellular communication systems named "IS-54B (ADC, D-AMPS, CDMA, IS-136)” in the United States of America, JDC in Japan and the global GSM-networks.
  • IS-54B ADC, D-AMPS, CDMA, IS-136)
  • the “scanning" radio receiver part according to the present invention must thus be in a position to handle the most frequently used mobile telephone systems within the area of use (and possibly facilitate upgrading to future specifications/protocols, for example "Bluetooth”, “Maya”, “Chat”, “e-mode”, “3G”, “SMS”, “WAP (/MEXE)", “iDEN”, “IMT-2000”, “GMPCS”, “GPRS”, “UMTS”, “FDMA”, and “(W) CDMA” with “FH/SS”, “DS/SS” and “CO FDM”), but in order to simplify the non-restricting description, GSM has been chosen. GSM is a commonly used standard for mobile telephones.

  • the method according to the present invention is mainly characterized by the features stated in the following Claim 1, and related subclaims, whereas the device for utilization of the method is disclosed in Claim 5 and the subclaims related to this claim.
  • mobile telephony is radio communication
  • same can be intercepted by devices known as scanners, which operate by continuously proceeding search of the radio frequency spectrum or chosen parts thereof, and which detect and "lock" on active channels, and submit intercepted sound to a listener.
  • scanners which operate by continuously proceeding search of the radio frequency spectrum or chosen parts thereof, and which detect and "lock" on active channels, and submit intercepted sound to a listener.
  • digital communication such as GSM
  • the output would be a meaningless noise, unless they are capable of performing a speech and signal data decoding operation with use of the same protocol as used for the intercepted signal.
  • such scanners are today commercially available, which are also capable of detecting the number dialled from the mobile telephone and also to disclose their individual and unique PIN (a subscriber's personal identification number - "International Mobile Subscriber Identity” - IMSI)/SIM number, particularly in the case when the mobile telephone is switched on from an off condition and when "hand shaking" is performed with the base station located closest to the subscriber with use of a few basic protocols, when also the protocols to be used for a subsequently following telephone call are disclosed to an initiated listener.
  • PIN subscriber's personal identification number - "International Mobile Subscriber Identity” - IMSI)/SIM number
  • the visitor's mobile telephone is located in such a close relationship to the entrance as a normal entrance request situation requires, before same can be detected, prevents all other persons switching on their mobile telephones in an adjacent area from addressing or initiating the system according to the present invention.
  • the antenna used by the system can thus be well screened, being directional and having a short reception range.
  • a "switched off" mobile telephone which is switched on also acts as a starting or activating unit for the system, apart from the fact that same generously gives away the protocols facilitating an "entrance call".
  • the radio receiving "scanning" unit in the described system will, after being activated, perform scanning of assigned radio channel (frequency) for communication and perform synchronisation with transmitted time divided TDMA parcels. It may thus detect, decode and handle the number that the visitor will dial in order to make a request for access to the building. This number is typically the telephone number of a tenant living in the building.
  • a programmable device, a "number discriminator” compares this number with preprogrammed numbers - normally the telephone numbers of the tenants and/or other persons authorized to unlock the door - and if these numbers correspond, the door lock is allowed to receive and be activated by an unlock command.
  • the system according to the present invention thus operates in synergy with the mobile telephone call, it does not take any part in any telephone communication, to which it is only acting as a passive listener, and when reacting on stimulus from same, it does not influence the actual conversation, which is carried out and completed (logically after intended result) by the parties concerned, and furthermore is the call without charges for the building - normally is the visitor charged to call fee unless a 1-800 (free of charge) number is offered, whereby the need for a communication unit for visitors no longer exists, such as a keyboard, microphone and loudspeaker - and furthermore will excellent sound quality be achieved, well suited for use in an area having street sounds.
  • the described system can also offer a code lock possibility, as is the case with known entrance telephone systems. This is advantageous for tenants, service personnel etc., as well as to give tenants having no telephone a possibility to let in visitors by giving them a door opening code.
  • the system according to the invention can obviously also include a keypad, for addressing a code lock, but this would mean additional hardware and an external user influenced unit which is sensitive for influence/damage.
  • a number dialled from a mobile telephone must not necessarily be a functioning/existing telephone number which is transferred to the base station (or in the air). All numbers dialled are transmitted after a command and "authenticated” (authentication) by the base station, and by preferably starting with a non-numerical part such as "*" or "#” it will, as disclosed above, reach and be understood by the described system. Should this number correspond to a number stored in the number discriminator for a certain code lock purpose, intended function can be performed, in the same way and with same advantages, e.g. time zones, as for a code lock having a keypad, even though no keypad exists.
  • a system according to the present invention can obviously also be equipped with a suitable type of card reader (this may also include a conventional physical card reader which reads the SIM card of the "visiting mobile", removed from the telephone and inserted into the reader), but it may also use mobile telephones for accomplishing a corresponding function, without the need for any external user unit.
  • a GSM mobile telephone When a GSM mobile telephone is switched on, same discloses during the initial handshaking operation with the base station its unique "PIN-code/SIM-card" number (amongst other information required to reach correct base station) in a format and according to a protocol which can be read by the now activated described system.
  • the mobile telephone acts very much the same as a "proximity card” and the system as a “proximity card reader” which reads the card without direct physical contact, and programming can be performed as "card only", or alternatively as "card-plus-code sequence” with required code sequence being inputted subsequently.
  • proximity card reader which reads the card without direct physical contact
  • programming can be performed as "card only”, or alternatively as "card-plus-code sequence” with required code sequence being inputted subsequently.
  • PIN/SIM code etc. transferred "automatically" from the visiting mobile when switched on and conventional dialled number
  • other types of automatically or intentionally transferred signals from the mobile can be used for the above code lock/card functions.
  • the described system should include a speech handling unit, mainly in order to detect and decode DTM F signals sent as speech data, same may theoretically also accept voice and speech commands for its functions/actions, but DTMF is believed both simpler and better for the relatively few tasks that an entrance surveillance system has to perform.
  • commands consist of longer DTMF code sequences, as well as different command codes for different called inhabitants (based on the different call numbers of same) for same type of actions, or for actions specific for only certain inhabitants, such as permitting a lift to reach a certain floor level, but normally is only one or a few DTMF digits required to achieve required extent of signalling with adequate security, since same in fact must originate from the called party, and amongst other criteria, preferably also within a predetermined time frame in a by the base station authenticated call.
  • GSM-scanners can be used for radio frequency scanning and reception, time adjustment and synchronization, and signal/speech decoding required for utilization of the present invention
  • the speech must never leave its digitized format to be transformed to an analogue signal audible to a listener; each system function is preferably in digital format. Accordingly, when using such devices a considerable part of their functions are not utilized, but since they are available and can be used, same confirms that described functions can be achieved in a number of ways and by use of standard components.
  • Programming the system according to the invention can be carried out in a number of ways, e.g. in position by means of a serial connection and with a handheld programming device or a PC (or PC-capable mobile telephone), and programming from a PC at a distant location via modem is also possible.
  • the system may also receive DTMF or, if adapted thereto, data via mobile telephone (WAP, SMS etc.) as programming commands, provided that somebody (authorized, e.g. by PIN/SIM number) is in place and establishes a mobile telephone call to an authorized programming telephone, in which case the described system can listen to the communication therebetween and thus receive the correctly formatted programming instructions/commands.
  • WAP mobile telephone
  • SMS mobile telephone
  • It may also be arranged with a connection to a public telephone network for distant programming purposes, as well as, for example, a mobile telephone subscription of cash card type or via Internet, typically not utilized for speech communication, but possibly used, for example, for alarm transmission purposes and surveillance/control purposes of functions within the building.
  • Non-existence of external physical user units results in a highly secure substantially non-external installation, protected against external influence and damage, and expensive parts and covers are not required.
  • Normally, only a few instructions are required (even though same may be an electronic display or similar, as well as audio/voice synthesized instructions, which on the other hand increases the costs and the risk for damage, but still remains as a possibility), and with indication of the area within which the mobile telephone should be switched on, even though this is not absolutely necessary for an experienced user, whereby nothing is required that would damage the looks, integrity and security of a beautifully designed entrance, even though same is equipped with an entrance surveillance system.
  • Ring signals and engaged signals can also be detected, since they are sent back to the calling telephone from the side of the called telephone, and can thus be detected by the described system and be utilized for additional purposes, for example, as known from existing entrance telephone systems, to start a time period allowed for DTMF detection only as from detection of reply (end of ring signals); the time period allowed for calling (between dialled telephone number and reply) and possibly also to specify separately the time of the call.
  • DTMF detection only as from detection of reply (end of ring signals); the time period allowed for calling (between dialled telephone number and reply) and possibly also to specify separately the time of the call.
  • the described embodiment will be related to the GSM standard, which, as already mentioned, is a MC/TDMA/TDD format for communication between mobile telephones (not shown) and base stations (not shown).
  • GSM Global System for Mobile communications
  • base stations not shown
  • all types of telephones and other "telephone related" apparatus e.g. modems, computers etc., that can be reached by a call from a mobile telephone are also not shown, and same can be connected to a wired telephone network but also consist of mobile telephones.
  • page 2 has the almost strigic scenario with regard to available mobile systems been discussed.
  • GSM has today the largest number of users, and this fact is the main reason why same has been chosen for the example of an embodiment. However, also this system is relatively difficult to describe in brief terms.
  • Fig. 1 discloses DECT.
  • DECT is allocated certain "frequency bands" for wireless radio communication in which a number of carrier waves are available.
  • Each carrier wave is divided in time periods having twenty-four "time slots”.
  • Two time slots are utilized to create a duplex channel, which means that twelve speech channels exist within the range of each carrier wave.
  • Said twenty-four time slots are transmitted as so called TDMA frames having a frame cycle time TF of 10 ms.
  • a typical frame structure for a digital TDMA/TDD communication system is shown in Fig. 1. During the first half of the frame, i.e. the first twelve time slots denominated R1, R2 ...
  • R12 data are received from the base station, whereas during the second half of the frame, i.e. the second group of twelve time slots denominated T1, T2 ... T12, the telephone unit is transmitting data to the base station.
  • a radio connection between a base station and a telephone unit is assigned a time slot in the first half of the time frame and a time slot having the same number in the second half of the time frame.
  • Each time slot normally includes synchronizing data, control data and digitalized speech or user data.
  • Signalling data such as data referring to the calling party, dialled telephone number and call progress signals can be included in control data as well as speech/user data.
  • Digital cellular systems must be even more complicated, but differ from the above by having individual radio frequencies (carrier waves) for transmission and reception (according to present and previous GSM).
  • Fig. 2 shows a simplified block diagram disclosing the described system 1, including four essential building blocks, i.e. a central controlling user adapted logical unit 2, a radio unit 3, a time controlling and synchronizing control unit 4 and a speech treating unit 5.
  • the radio unit includes an atmospheric interface by means of an antenna 6, connected to the radio unit 3 and including a searching "scanning" part and a receiver/demodulator.
  • Time adaption during reception is controlled by the time controlling unit 4, which, in the case of TDMA/TDD technology, handles synchronization of frames and time slots in a known fashion.
  • the time reference is normally gained from a synchronizing signal received by the antenna 6.
  • said antenna is preferably of receive type only, screened and of directional type, whereby same has a very short, narrow and defined reception range wherein same well receives radio signals within the frequency band(s) utilized for mobile telephony within the installed area.
  • a first phase which can be called the "resting phase”
  • said antenna can under ideal conditions only be activated by signals from the predetermined area (which usually requires certain calibration in position, e.g. when the system is installed), but a nearly “ideal” condition is also acceptable due to the following protocol.
  • the antenna connected to a searching ("scanning") device, which constitutes the first part of the radio unit 3.
  • This searching device searches during the first phase continuously the frequency bands used for a suddenly occurring relatively strong radio signal on any of the frequencies. This is a reason why it is preferred that a visitor should switch on a "disconnected" mobile telephone adjacent to the entrance in order to initiate the entrance telephone procedure.
  • Such a scanner would be a luxury, since reproduction of speech is not required, and since most of these scanners are built to cover the entire radio spectrum; totally unnecessary in the present case.
  • a discrete circuit, LSI circuit or a few commercially available IC circuits would be more suitable to implement the functions described herein, surveillance/"scanning" only within required narrow bands, and surveillance of the handshaking procedure, and gaining only a few desired parameters from same.
  • Technically can this be accomplished today in a number of ways by a person skilled in the art and by use of commercially available standard components, and in view of this fact a more detailed description of a certain embodiment is not believed required and would only constitute a non-required restriction.
  • a "scanning" device After having been initiated in previously described fashion are (if previously described "proximity card” and/or transaction memory possibility are used, to deal with data including PIN/SIM number or corresponding equivalents and secure that same are transferred for adequate treatment) to connect another antenna (or part of an antenna) facilitating reception at a large distance, which results in reception also from the base station and possibly power reduced mobile telephone signals, and to transfer same to the more stable parts of the radio unit 3. Mentioned reduction/increase of the receiving range can also be carried out in other fashions, e.g. by use of a connectable and disconnectable attenuating unit.
  • the system according to the invention now enters into “active” condition, and it is transferred back to "resting” condition after having completed intended/instructed actions, or by disconnection after a predetermined time period.
  • active condition no “scanning” is performed, since only one visitor at the time requires to be handled at an entrance.
  • satellite stations are preferably by means of a "multiplexed system” connected to a central main unit, which may have the entire capacity for handling calls and the main part of hardware, thereby reducing the costs for the installation.
  • the central control unit 2 receives data from the radio unit 3. Signalling and synchronization information are removed from received data, and resulting speech data are transferred to the speech treating unit 5, which decodes received data. It should be noted, that according to described embodiment, unless speech/voice commands are utilized, preferably only DTMF signals are of interest, which are included in the flow of speech from the party called by the telephone, and only when a valid and preprogrammed telephone number has been dialled from the visitor's mobile telephone; and that DTMF signals are fairly easy to detect and decode from a speech data stream.
  • the unit 5 preferably maintains received "T" speech data and preferably also all control data for internal treatment, preferably in order to obtain the number dialled by the visitor's mobile telephone and which is transferred after "handshaking". This number may thereafter be compared with the numbers stored/programmed in the number discriminator 7 in order to ascertain whether or not corresponding, and should this not be the case, the system may immediately return to "resting" status.
  • a door lock for example, may be immediately unlocked followed by return to "resting".
  • the unit 5 can be started pending incoming "R" data and for detection of in such data included DTMF signals, and provided that such are located within a predetermined time limit, corresponding to programmed criteria, corresponding action can be performed. After completion of programmed action, and also at reception of a non-valid digit/code command and/or expiration of time period for surveillance, the described system can return to "resting".
  • the central control unit 2 In the case of multi carrier wave/multi time frames, such as GSM, the central control unit 2 normally also controls the various combinations of carrier wave frequencies and time frames in a known fashion. In order to minimize the number of required components, the unit 2 may according to the present invention be configured in such a way that same helps the "scanner" to lock on assigned carriers/time frames. According to the described embodiment is the control unit 2 arranged to handle received signal information for decoding a transmitted dialled number from a mobile telephone at the entrance, for comparison with programmed/stored numbers, and for possibly taking actions based on the instructions associated with said number. This is carried out by the schematically indicated number discriminator denominated 7.
  • the number discriminator 7 can be integrated with the control unit 2, and may substantially comprise of a for the purpose adapted micro control circuit, which furthermore may be integrated with the control unit 2 and perform substantially all steps associated with same. It includes an operative memory, in which all operative programs are stored. Furthermore, same also includes memory means including data for a number of decoding logarithms, for example adapted to the type of signalling information that must be decoded for a certain purpose. These decoding algorithms are fetched and treated together with received signalling information to reveal instructions for an action.
  • the memory means also facilitates possibility for adapted and/or personal user programming (which for applications requiring high security, such as military applications, may include memory components which can not be reprogrammed by "external persons"), such as programming/storage of desired actions, choice of decoding algorithms from the users of the system depending on requirements and circumstances, and/or programming of user specific information, e.g. telephone numbers, code lock numbers, numbers for "proximity cards”; if and how this information should co-act; DTMF digits/codes to be used for instructions from the called telephone; etc., as well as temporary information, e.g. parameters relating to time periods whereunder certain functions are allowed/not allowed.
  • at least one serial port and a real time clock are advantageously arranged.
  • the system 1 may furthermore include a keypad 8 (and/or, for analogue purposes, an IR receiver, "Bluetooth” receiver or similar), an optional card reader 9 (and/or for analogue purposes, a “biometrical” reader or similar) and an optional display unit 10. It is connected to a power source 11, and is shown connected to an entrance lock 12 for influence of same. A connection to a block 13 is also shown, which is intended to illustrate a number of possible added options, e.g. a TV camera, a device for announcing a visitor via cable network, a light source, transmitting status data, or any other desired device/procedure.

  • the reply in block 21 should be "no"
  • the number is transferred to block 23, which ascertains whether or not the number is a telephone number programmed into the number discriminator 7 as a number which at the actual time of day is authorized to control some related functions/actions in the building. If the reply is "no", the system is reset and returns to block 14. If the reply is "yes”, the flow of operations is moved to block 24, in which the speech treating unit 5 starts waiting for reception of "R" speech data (i.e. a reply to the telephone call), and if this should occur, detection and decoding of any possible DTMF signals in same during a predetermined time period for this purpose.

  • Mobile telephones utilizing other types of systems than GSM can be used, many different decoding algorithms/routines can be used to meet various needs, and also other command types than DTMF can be used, e.g.
  • SMS, WAP can also be used, and some functions can, provided that the operator supplies such services, be handled/implemented by the base station, and may, for example via "menu choice", be included amongst the services and functions included in the mobile telephone, if also supported by the manufacturer.

  3. Procédé selon la revendication 1 ou 2, dans lequel l'extension géographique de la zone de réception pour le récepteur utilisé est maintenue restreinte pendant la réalisation des étapes initiales, et dans lequel la zone de réception, par la suite, est étendue afin de faciliter la réception de la station de base avec laquelle le radiotéléphone mobile communique.
  4. Procédé selon l'une quelconque des revendications 1 à 3, dans lequel le radiotéléphone mobile utilisé est commuté à partir d'un état inactif dans la zone couverte par le récepteur, déclenchant ainsi une procédure d'authentification avec une station de base adjacente, ladite station de base pouvant être reçue par le récepteur en raison d'une extension de la zone de réception.
  5. Dispositif de réalisation du procédé d'utilisation de radiotéléphones mobiles à des fins de surveillance et/ou de contrôle selon l'une quelconque des revendications 1 à 4, comprenant une unité radio de réception (3) munie d'une antenne de réception associée (6), possédant un scanner de recherche destiné à la réception des fréquences utilisées dans la zone géographique en question pour une communication de radiotéléphone mobile, une unité centrale de contrôle (2) vers laquelle un signal reçu de la part d'un radiotéléphone mobile détecté par le scanner est transféré, et une unité de synchronisation temporelle (4) destinée à la surveillance et au décodage d'une procédure d'authentification complète entre le radiotéléphone mobile et une station de base associée et, ainsi, d'un numéro PIN/SIM reporté et/ou d'un numéro d'appel transféré par le radiotéléphone mobile, moyennant quoi la conformité avec des informations stockées correspondantes est agencée afin de déclencher un processus ou une action prédéterminé(e), ou d'entraîner un retour à l'état de "veille" et d'écoute, afin d'attendre un nouveau signal transmis.
  6. Dispositif selon la revendication 5, dans lequel l'unité radio de réception (3) est agencée comme ayant une zone de réception géographique restreinte, ladite zone étant étendue lorsqu'un signal entrant a été déterminé comme un appel vers un abonné préprogrammé, et dans lequel l'unité radio (3), par la suite, pendant une période de temps prédéterminée, écoute le canal de communication de l'abonné appelé via une unité de traitement de parole (5) en vue de commandes préprogrammées sous la forme de signaux DTMF, la réception de cette commande approuvée entraînant la réalisation d'une procédure/d'une action prédéterminée associée, ou un retour à l'état de "veille" et d'écoute, afin d'attendre un nouveau signal transmis.
  7. Dispositif selon l'une quelconque des revendications 5 et 6, dans lequel l'unité centrale de contrôle (2) est également reliée afin d'être influencée par un moyen de saisie physique actionné par un utilisateur, tel que par exemple un pavé numérique (8), un lecteur de cartes (9) ou similaires, et dans lequel ces commandes, via ce moyen (8 ; 9), sont agencées afin de provoquer, individuellement ou en combinaison/en échange avec des informations obtenues de la part d'un radiotéléphone mobile, le déclenchement de la réalisation d'une procédure et/ou d'une action prédéterminée.
  8. Dispositif selon l'une quelconque des revendications 5 à 7, dans lequel l'unité radio de réception (3), lorsqu'un appel approuvé vers un abonné a été confirmé, est agencée afin d'écouter le flux de données de parole de l'abonné appelé, et, ainsi, afin de recevoir et d'accepter uniquement des commandes possibles existant dans le flux de données de parole de l'abonné appelé, introduites sous forme de séquences DFMT, de commandes de parole ou similaires.
  9. Dispositif selon l'une quelconque des revendications 5 à 8, dans lequel une séquence de chiffres composée par un radiotéléphone mobile et commençant par une partie non numérique, comme par exemple "*" ou "#", est reçue et interprétée comme une commande directe qui, lorsqu'elle correspond à une commande préprogrammée, entraîne le déclenchement et la réalisation d'un processus/d'une action prédéterminée(e), comme par exemple une commande de blocage de code destinée à ouvrir une porte d'entrée.
  10. Dispositif selon l'une quelconque des revendications 5 à 9, dans lequel l'étendue de réception géographique de l'unité radio de réception (3) à l'état de "veille" est tellement restreinte que celle-ci ne réagit sensiblement qu'aux signaux provenant d'un radiotéléphone mobile qui est commuté à partir d'un état déconnecté dans la zone de réception, c'est-à-dire lorsque le radiotéléphone mobile ayant une puissance de sortie sensiblement complète tente d'établir un contact avec une station de base adjacente afin d'effectuer un processus d'authentification.
  11. Dispositif de réalisation du procédé d'utilisation de radiotéléphones mobiles à des fins de surveillance et/ou de contrôle selon la revendication 1, le récepteur destiné à la réception de signaux provenant de radiotéléphones mobiles comprenant une unité de réception destinée à signaler par infrarouges la réception de signaux infrarouges de la part d'un radiotéléphone mobile équipé d'une interface de communication infrarouge, dans lequel ladite unité de réception est agencée afin de transférer un signal infrarouge reçu entre un radiotéléphone mobile et une unité centrale de contrôle à des fins de surveillance et de décodage des signaux infrarouges reçus de la part du radiotéléphone mobile, lesdits signaux reçus comprenant un numéro PIN/SIM reporté ou des informations correspondantes et/ou une séquence de numéro appelé transférée par le radiotéléphone mobile, moyennant quoi la conformité avec des informations correspondantes stockées est agencée afin de déclencher un processus ou une action prédéterminé(e), ou d'entraîner un retour à un état de "veille" ou d'écoute, afin d'attendre un nouveau signal infrarouge reçu par l'unité de réception.
