Description

APPAREILS POUR FILTRER LES RADIOTELEPHONES APPARATUS FOR FILTERING RADIOTELEPHONES
La présente invention concerne un appareil pour filtrer les radiotéléphones dans des espaces déterminés, et en variante, de les localiser.The present invention relates to an apparatus for filtering radio telephones in specific spaces, and as a variant, for locating them.
Le nombre de radiotéléphones rend leur sonnerie ou leur utilisation gênante dans certains endroits: salles de spectacles, cinémas, restaurants, bibliothèques, dortoirs, ... .Dans d'autres endroits, leur utilisation est interdites: prisons, salles d'examen, ...The number of radiotelephones makes their ringing or their use troublesome in certain places: performance halls, cinemas, restaurants, libraries, dormitories, ... In other places, their use is prohibited: prisons, examination rooms,. ..
Les différentes catégories de moyens ont déjà été décrites dans les brevets FR 9707000, FR 9710105 et WO 98/56130.The different categories of means have already been described in patents FR 9707000, FR 9710105 and WO 98/56130.
Les solutions qui peuvent être légalement acceptées doivent respecter certaines contraintes:Solutions that can be legally accepted must respect certain constraints:
- laisser passer les appels d'urgence, - laisser passer certains abonnements prioritaires- let emergency calls through, - let through certain priority subscriptions
( médecins, pompiers, police, ...),(doctors, firefighters, police, ...),
- être identifiés et autorisés ...- be identified and authorized ...
Les solutions de brouilleurs qui ne respectent pas ces contraintes risquent d'être interdites dans la plupart des pays. Plusieurs variantes décrites dans les brevets ci-dessus respectent ces contraintes.Jammer solutions that do not meet these constraints may be banned in most countries. Several variants described in the above patents respect these constraints.
Le présent brevet a pour but de détailler une catégorie de variantes de filtres de radiotéléphones:The purpose of this patent is to detail a category of variants of radiotelephone filters:
- filtres ayant pour but de modifier les signaux entre les stations de base et les radiotéléphones, dans le but de faire fonctionner les radiotéléphones dans un mode de service restreint en utilisant des classes d'utilisateurs, et cela, selon 2 types de moyens:- filters intended to modify the signals between the base stations and the radiotelephones, with the aim of operating the radiotelephones in a restricted mode of service by using classes of users, and this, according to 2 types of means:
- micro stations de bases adaptées, - répéteur de stations de base.- adapted micro base stations, - base station repeater.
Ces principes sont applicables aux différents systèmes de radiotéléphonie numériques (GSM,UMTS, ...). La première variante utilise des micro stations de base avec leur technologie habituelle et intégrées dans le système de radiotéléphonie (1 cellule par station). La présente variante de l'invention utilise ces micro-stations non pas en service normal mais dans le but de filtrer les radiotéléphones d'un lieu donné. Pour cela, ces micro-stations doivent être utilisées avec des moyens de couverture radio très sélectifs en volume, de façon à couvrir le plus précisément le lieu à protéger . Ces micro-stations, pilotées par le système d'ensemble, et identifiées comme stations de filtrage peuvent permettre un filtrage au niveau supérieur ( fichier des abonnés ... ) ou gérer les radiotéléphones présents en mode restreint permanent en utilisant les classes d'abonnés. Leur utilisation non conventionnelle leur permet de remplir le rôle de filtre au lieu d'avoir pour but d'augmenter la couverture de l'ensemble. Leur implantation comportera 2 particularités:These principles are applicable to the various digital radiotelephony systems (GSM, UMTS, ...). The first variant uses micro base stations with their usual technology and integrated into the radiotelephony system (1 cell per station). The present variant of the invention uses these micro-stations not in normal service but for the purpose of filtering the radiotelephones of a given place. For this, these micro-stations must be used with radio coverage means that are very selective in volume, so as to more precisely cover the place to be protected. These micro-stations, controlled by the overall system, and identified as filtering stations can allow filtering at the higher level (subscriber file ...) or manage the radiotelephones present in permanent restricted mode using the subscriber classes . Their unconventional use allows them to fulfill the role of filter instead of having the aim of increasing the coverage of the whole. Their establishment will include 2 particularities:
- puissance supérieure à celles des autres stations environnantes, de façon à capter les mobiles présents.- higher power than those of other surrounding stations, so as to pick up the mobiles present.
- moyens radio de couverture très sélectifs de façon à couvrir uniquement le lieu à filtrer: antennes directives en angle, câbles rayonnants, capteurs répartis,- very selective radio coverage means so as to cover only the place to be filtered: directional antennas at an angle, radiating cables, distributed sensors,
La seconde variante est constituée de répéteur des signaux des stations de base en les modifiant. L'appareil est constitué :The second variant consists of repeater of the signals of the base stations by modifying them. The device consists of:
- d'une antenne de réception des signaux des stations de base active dans le lieu à surveiller,- an antenna for receiving signals from base stations active in the location to be monitored,
- d'une antenne sélective de ré-émission de ces signaux , après modification des codes de classes de service.- a selective re-transmission antenna for these signals, after modification of the service class codes.
Cette ré-émission doit être sélective à destination unique du lieu à protéger, en utilisant les moyens radios déjà décrits ci-dessus. La ré-émission doit être de même fréquences que celles des stations de base et modifiée pour provoquer le basculement des radiotéléphones présents en mode restreint . La modification concerne, par exemple, le BCCH pour GSM, émis par la station et permettant au mobile de se caler sur la station la plus puissante.This re-emission must be selective for a single destination of the place to be protected, using the radio means already described above. The retransmission must be of the same frequencies as those of base stations and modified to cause the switchover of radio telephones present in restricted mode. The modification concerns, for example, the BCCH for GSM, issued by the station and allowing the mobile to lock onto the most powerful station.
L'utilisation des catégories d'utilisateurs existant dans la norme GSM permet la sélectivité du filtrage.The use of the categories of users existing in the GSM standard allows the selectivity of the filtering.
Les radiotéléphones restent connectés sur les fréquences des stations de base normales du réseau , ce qui permet les communications autorisées.The radiotelephones remain connected on the frequencies of the normal base stations of the network, which allows authorized communications.
Cette méthode ne modifie pas l'affectation du mobile à une station et permet sa localisation dans la cellule. Ce répéteur, peut, en variante, avoir un module de liaison avec les stations de base, ce qui permet à ces dernières de piloter le répéteur (activation ou désactivation... ) ou au répéteur de signaler l'opération de filtrage à la station émettrice.This method does not modify the assignment of the mobile to a station and allows its location in the cell. This repeater can, as a variant, have a link module with the base stations, which allows the latter to control the repeater (activation or deactivation, etc.) or the repeater to signal the filtering operation to the station. transmitter.
L'identité du mobile peut être récupérée pour être transmise en émettant un signal d'appel vers le mobile et ainsi en provocant son émission vers le répéteur ou la station.The identity of the mobile can be retrieved to be transmitted by transmitting a call signal to the mobile and thus by causing its transmission to the repeater or the station.
La répétition des signaux concerne les différents opérateurs, par contre, le pilotage peut être réalisé par un opérateur principal. Dans ce cas, l'identification du répéteur peut être réalisée par une carte SIM (ou équivalent). La modification des signaux répétés peuvent porter sur d'autres parties des signaux et permettre d'autres fonctionnalités, en fonction des normes des mobiles. La commande des mobiles peut permettre, par exemple, une adaptation des tarifications en fonction du lieu. La majeure partie des composants de ce répéteur peuvent être de même nature que ceux utilisés par les mobiles avec utilisation ou non d'une ou plusieurs carte SIM.The repetition of the signals concerns the different operators, on the other hand, the control can be carried out by a main operator. In this case, the identification of the repeater can be carried out by a SIM card (or equivalent). The modification of the repeated signals can relate to other parts of the signals and allow other functionalities, according to the standards of the mobiles. Ordering mobiles can allow, for example, an adaptation of prices depending on the location. The major part of the components of this repeater can be of the same nature as those used by mobiles with or without the use of one or more SIM cards.
La figure 1 représente une station de base F affectée à un local à filtrer L situé dans une cellule plus large C. La micro-station de filtrage F émet à une puissance supérieure et contrôle ainsi les mobiles présents grâce à ses moyens radio sélectifs S. La figure 2 représente un répéteur F qui amplifie les signaux des émetteurs E en les modifiant pour basculer les mobiles présents en service restreint dans un lieu L. Le signal initial a est répété après modification en b. La présente invention permet le filtrage d'un lieu donné, tout en laissant passer les appels d'urgence et certaines catégories d'abonnés.FIG. 1 represents a base station F assigned to a room to be filtered L situated in a larger cell C. The filter micro-station F transmits at a higher power and thus controls the mobiles present thanks to its radio selective means S. FIG. 2 represents a repeater F which amplifies the signals of the transmitters E by modifying them to switch the mobiles present in restricted service in a place L. The initial signal a is repeated after modification in b. The present invention allows filtering of a given location, while letting through emergency calls and certain categories of subscribers.
En annexe, elle permet la localisation des mobiles en vue d'opérations diverses: facturations suivant le lieu par exemple. In the appendix, it allows the location of mobiles for various operations: invoicing according to location for example.
