Abstract

The invention relates to a mobile telecommunication equipment (1) and a method of detecting the theft of one such equipment. According to the invention, an alarm module (6) for the equipment (1) comprises a short-distance sender/receiver (6a) which can, as a minimum, receive at least one code identifying the owner of the equipment (1) from a short-distance send/receive module (7) which is external to said equipment. A memory element (6d) of the alarm module (6) is used to store at least one equipment (1) owner identification code. A microcontroller (6c) of the module (6) receives the received identification code from the sender/receiver (6a) and compares same to at least one equipment (1) owner identification code which is stored in the aforementioned memory element (6d), such that, when the identification code received is not the same as the stored identification code, the alarm module (6) is activated. Moreover, the module (6) is also activated when the sender/receiver (6a) receives no code. The invention also relates to a short-distance send/receive module which is intended to send at least one identification code to the sender/receiver (2a), said module being integrated into a fixed or mobile element (7).

Description

The present invention relates to telecommunication equipment mobile, a short-distance transmission-reception module able to work with this equipment and a method of detecting theft of this equipment.

• des moyens de dialogue destinés à communiquer avec un serveur de gestion d'alarmes par l'intermédiaire d'un réseau de télécommunication mobile.

More particularly, the present invention relates to mobile telecommunication equipment comprising:

• dialogue means for communicating with an alarm management server via a mobile telecommunication network.

Such equipment is for example described in the patent application French No. 01 12292 in the name of the plaintiff.

More precisely in this document, the alarm module is a stimulus detector connected to the means of dialogue so that when said detector detects a stimulus (presence or absence of electric current in equipment, noise, light, heat, moving equipment, movement close to the equipment), the means of dialogue address the minus an alarm message to an alarm management server.

The first disadvantage of such an alarm module lies in the fact that it minimizes the mobile phone part.

Another disadvantage is that the stimulus detector should be as discreet as possible, while the equipment of telecommunication to be protected is naturally visible since handled in its current use. The stimulus detector, when it is found by the thief, is usually destroyed or thrown away. Stolen telecommunications equipment is not not supposed to be destroyed by the thief, but some of its components may to be modified (SIM card for example). Such components are therefore better protect.

Finally, the stimuli and mode of operation of the alarm module are not perfectly adapted to the use of telecommunication equipment mobile. The stimulus detectors mentioned in the patent application French No. 01 12292 are too complex or too cumbersome or too expensive to miniaturize. Indeed, a type of mobile telecommunication equipment mobile phone becomes over the years increasingly small and manageable and does not must or may be encumbered with marginal components that are too cumbersome or too expensive to miniaturize, and thus, in some cases, unsuitable.

We will now describe, with reference to FIG. flight detection system in which the equipment of mobile telecommunications and the short-distance transmission-reception module according to the invention.

Mobile telecommunication equipment is designated by the reference numeral 1. In the example shown, the equipment 1 is a mobile phone.

The mobile telephone 1 comprises dialogue means 2 intended to communicate with an alarm management server 3 via a base station 4 (BTS) belonging to a mobile telecommunication network 5, for example the GSM network (Global System for Mobile Communications). As this has been described in the French patent application No. 01 01527, the server 3 is intended to receive, from the mobile phone 1, a message alarm that it refers to a telecommunication equipment 9 belonging to the owner, for example on the landline (home or office) of this latest. In the example shown, the alarm message is a short message SMS, for example, called "Alarm."

The mobile phone 1 also communicates with a module external short-distance transmission-reception system 7 which will be described in more detail in following the description.

As can be seen in Figures 2A to 2D, the mobile phone 1 further comprises an alarm module 6 which is connected to the dialogue means 2 in such a way that when the alarm module 6 is activated, the means of dialog 2 address at least one alarm message to the server 3.

• une unité centrale de traitement 2a,
• un émetteur-récepteur d'ondes radio 2b raccordé à ladite unité centrale,
• une antenne 2c raccordée à l'émetteur-récepteur 2b et assurant l'émission et la réception proprement dite des ondes radios reçues en provenance du réseau de télécommunication 5. A cet effet, l'antenne 2c est commandée par un amplificateur (non représenté),
• une carte d'identification d'abonné ou carte SIM 2d (« Subscriber Identification Module ») qui est reliée à l'unité centrale 2a et dans laquelle réside notamment un programme dit « Toolkit » connu en tant que tel pour effectuer des traitements internes (calcul, gestion de données),
• une mémoire de données 2e qui est reliée à l'unité centrale 2a,
• un programme conçu pour permettre au module 2 soit d'émettre des messages courts (« short messages ») ou SMS en direction du serveur 3 par l'intermédiaire de la station de base 4 et du réseau 5, soit de recevoir de tels messages en provenance du serveur 5, ledit programme résidant soit dans la carte SIM 2d (quand elle est inamovible : figure 2B), soit dans la mémoire 2e, soit enfin dans des secondes cartes SIM inamovibles 2f ou 2g, telles que présentées dans les figures 2C et 2D et décrites dans la suite de la description respectivement en référence aux troisième et quatrième modes de réalisation.

As can be seen in FIGS. 2A to 2D, the dialogue means 2 of the mobile telephone comprise, in a manner known per se:

• a central processing unit 2a,
• a radio wave transceiver 2b connected to said central unit,
• an antenna 2c connected to the transceiver 2b and ensuring the actual transmission and reception of the radio waves received from the telecommunication network 5. For this purpose, the antenna 2c is controlled by an amplifier (not shown) ,
• a subscriber identification card or SIM card 2d ("Subscriber Identification Module") which is connected to the central processing unit 2a and in which in particular resides a so-called "Toolkit" program known as such to perform internal processing ( calculation, data management),
• a 2nd data memory which is connected to the central unit 2a,
• a program designed to enable the module 2 to issue short messages or SMS to the server 3 via the base station 4 and the network 5, or to receive such messages in from the server 5, said program residing either in the SIM card 2d (when it is irremovable: Figure 2B), either in the memory 2e, or finally in second irremovable SIM cards 2f or 2g, as shown in Figures 2C and 2D and described in the following description respectively with reference to the third and fourth embodiments.

When the mobile phone 1 is stolen, the above program is in further designed to send to the server 3 location messages of the mobile phone 1. The location information contained in these messages are stored either automatically or periodically, in 2nd memory if it is a Bluetooth location as described in the French patent application No. 01 12292 in the name of the applicant, or well, in the alarm management server 3, if it is a GSM location. In the latter case, such a location can be carried out by triangulation, technology well known and controlled at the moment.

• un émetteur-récepteur courte distance 6a relié à l'unité centrale de traitement 2a et apte au moins à recevoir, en provenance du module d'émission-réception courte distance 7, externe au téléphone mobile 1, un code d'identification d'un propriétaire du téléphone mobile 1, ou encore d'une personne habilitée à utiliser un tel téléphone,
• un décodeur 6b relié à l'émetteur-récepteur 6a et apte à décoder le code d'identification reçu,
• un microcontrôleur 6c relié au décodeur 6b et apte à comparer le code d'identification décodé à un code d'identification du propriétaire du téléphone mobile 1 qui est enregistré dans une mémoire 6d reliée au microcontrôleur 6c, de telle façon que lorsque le code d'identification reçu n'est pas égal au code d'identification mémorisé le module d'alarme 6 est activé.

Still with reference to FIGS. 2A to 2D, the alarm module 6 of the mobile telephone 1 comprises:

• a short-distance transceiver 6a connected to the central processing unit 2a and able at least to receive, from the short-distance transmission-reception module 7, external to the mobile telephone 1, an identification code of a owner of the mobile phone 1, or of a person authorized to use such a telephone,
• a decoder 6b connected to the transceiver 6a and able to decode the received identification code,
• a microcontroller 6c connected to the decoder 6b and able to compare the decoded identification code to an identification code of the owner of the mobile phone 1 which is stored in a memory 6d connected to the microcontroller 6c, so that when the code of identification received is not equal to the identification code stored alarm module 6 is activated.

The module 6 is also able to be activated when the transceiver short distance 6a does not receive any identification code from of the module 7. In this case, the decoder 6b affects the absence of reception of identification code a code comprising for example a sequence of zeros. Such code is then compared in the microcontroller 6 in the same way as described above.

The dialogue means 2 and the alarm module 6 are elsewhere fed conventionally by a battery 8.

In the example shown, the short distance transceiver 6a is of the Bluetooth type with a limited range of action for example to 10m. he can however, be any other short-haul 802.11b transceiver or HomeRF for example, able to send and receive an identification code characterizing the persons entitled to use the mobile telephone 1. These three types of short-range transceivers, Bluetooth, HomeRF or 802.11b, operate in the same frequency band (ISM 2.4 Ghz) which is available in theory worldwide without a license.

It can even be envisaged that the short distance transceiver 6a of the alarm module 6 is able to capture identification codes in from short-haul transceivers belonging to different technologies.

It should also be noted that the Bluetooth identification code of the alarm module 6 can be issued following the request of an external equipment with a Bluetooth transceiver, as soon as the mobile phone is under pressure. Indeed, simply turning on the mobile phone puts also energized the alarm module which can then transmit, after request, its identification code, without any need to introduce on the mobile phone the PIN code. Obtaining this identification code therefore allows to authenticate remotely, without the need for PIN code, the legitimate owner of the mobile phone 1, as described in the application for French Patent No. 01 01527

In the example shown, the short transmission-reception module distance 7 is also of the Bluetooth type with a limited range of example at 10m. However, it may be any other short transceiver distance, type 802.11b or HomeRF or other, existing or future, and possessing an identification code or able to memorize one or more codes Identification.

As shown in FIG. 1, the transmission-reception module short distance 7 is embedded in an element that is fixed or mobile. Such item is normally in the possession of the rightful owner. In the example represented, this is a key ring.

• une housse de protection rigide du téléphone mobile 1 dans laquelle est intégrée une puce Bluetooth, une telle housse devant être utilisée obligatoirement en même temps que le téléphone lorsqu'on recharge ce dernier, ceci par souci d'avoir toujours le téléphone mobile et la housse en bon état de fonctionnement, ladite housse devant en outre être portée séparément du téléphone quand celui-ci est utilisé, en servant de porte téléphone attaché à la ceinture par exemple, afin que le processus automatique de sécurité décrit ci-dessous puisse fonctionner,
• tout élément adaptable au téléphone mobile lors de la recharge, tel que notamment les écouteurs ou microphone Bluetooth (ou autre) du propriétaire,
• un assistant numérique personnel (PDA), un baladeur ou encore un lecteur de cartes (à puces ou non)..., portés en permanence par le propriétaire et normalement séparés physiquement de son téléphone mobile 1, mais en fait reliés à ce dernier par une liaison radio de proximité (Bluetooth ou autre).
• tout équipement électronique incorporant un émetteur-récepteur Bluetooth (ordinateur personnel, véhicule, équipement ménager ou de bureau...) et maintenu à portée du propriétaire utilisant le téléphone mobile. Dans le cas d'un véhicule, un tel téléphone mobile laissé dans le véhicule, pourrait servir de détecteur de vol, aussitôt que le téléphone mobile est emporté seul par le voleur qui s'éloigne ainsi du véhicule, et devrait permettre ainsi de « pister » le voleur, et, peut-être, par voie de conséquence, le véhicule volé.

As an alternative to the key ring, the short-distance transmission-reception module 7 could be:

• a rigid protective cover of the mobile phone 1 in which is integrated a Bluetooth chip, such a cover to be used compulsorily at the same time as the phone when charging the latter, this for the sake of always having the mobile phone and the cover in good working order, said cover must also be worn separately from the phone when it is used, serving as a telephone door attached to the belt for example, so that the automatic security process described below can work,
• any item adaptable to the mobile phone during charging, such as the owner's Bluetooth headphones or microphone (or other),
• a personal digital assistant (PDA), a player or even a card reader (bullets or not) ..., permanently worn by the owner and normally physically separated from his mobile phone 1, but in fact connected to it by a proximity radio link (Bluetooth or other).
• any electronic equipment incorporating a Bluetooth transceiver (personal computer, vehicle, household or office equipment, etc.) and kept within the reach of the owner using the mobile phone. In the case of a vehicle, such a mobile phone left in the vehicle, could serve as a theft detector, as soon as the mobile phone is carried alone by the thief who moves away from the vehicle, and should thus allow to "track The thief, and perhaps, consequently, the stolen vehicle.

• nombre de messages SMS à envoyer en cas d'alarme,
• liste des personnes ou entités autorisées par le propriétaire du téléphone à qui adresser les messages SMS,
• durée de fonctionnement du module d'alarme 6,
• date, heure, information de localisation du téléphone mobile 1.

Referring back to FIG. 1, the alarm management server 3 is operated by a telecommunication operator or by a third party provider of the "mobile phone theft detection" service from which the owner of the telephone has previously subscribed. mobile 1. Server 3 has a database that contains at least the following parameters:

• number of SMS messages to be sent in the event of an alarm,
• list of people or entities authorized by the owner of the phone to whom to send SMS messages,
• operating time of the alarm module 6,
• date, time, location information of the mobile phone 1.

These parameters may be modified at will by the owner of the mobile phone 1 by connecting it to the server 3.

According to a first mode of operation or "mode 1" of mobile phone 1 shown in Figure 2A, the microcontroller 6c of the module alarm 6 controls the transceiver 6a for the latter to transmit in direction of the key ring 7 a request for the supply of at least one code Bluetooth identification number of the mobile phone owner 1.

The issuance of such a request is carried out as the mobile phone 1 whether or not within the range of the key ring 7. It is also performed in fixed time intervals or during use, by a holder of the mobile phone 1, at least one feature of the latter.

• la mise en état de veille du téléphone mobile 1 (test A),
• la recharge de la batterie 8 (test B),
• l'activation de l'émetteur-récepteur 2b du téléphone mobile 1 (test C),
• le changement de carte SIM 2d (test D),
• la recherche d'accès aux contenus mémoire (agenda, répertoire, jeux, videos, fichiers, mails, SMS,...) (tests non représentés).

As can be seen in FIG. 3A, such a functionality consists for example of:

• the standby state of the mobile phone 1 (test A),
• charging the battery 8 (test B),
• the activation of the transceiver 2b of the mobile phone 1 (test C),
• 2d SIM card change (D test),
• the search for access to the memory contents (agenda, directory, games, videos, files, mails, SMS, ...) (tests not shown).

Following receipt of this request, three cases may occur:

1 ^st case: the key ring 7 is under tension

If the key ring 7 is on, it sends to the transceiver 6a of the alarm module 6 a Bluetooth identification code.

The received code is decoded by the decoder 6b and then compared to the code identification stored in the memory 6d through a program designed in the microcontroller 6c (test E in FIG. 3A).

If the mobile phone 1 is within the range of the key ring 7, the received identification code is equal to the stored identification code. In consequence, the mobile phone 1 operates normally as if the user of the latter was the owner or an authorized person.

If the mobile phone 1 is not within the range of the key ring 7, the identification code received by the mobile phone 1 can not be that of the key ring. If the code received (from another equipment electronic code) is an authorized code (identical to one of the identification codes stored), the mobile phone 1 operates normally. If the code received is not authorized or if the mobile phone 1 receives no code, the alarm module 6 is still activated, as described above in the description.

In addition, when using at least one service provided by the telephone mobile 1, the activation information of the alarm module 6 is then transmitted via the central processing unit 2a, to the transceiver 2b of the mobile telephone 1. The latter immediately sends an SMS alarm message to the network of telecommunication 5 via the base station 4 with which he is in contact with the moment of the activation of the module 6. This SMS message is then received by the Alarm Management Server 3. As can be seen in Figure 1, the latter returns this message, in the same form (text) or in a different form (voice message, e-mail, etc.), on a telecommunication station 9 (landline, mobile or Internet or other) owned by the owner of the phone mobile 1 or to a third person chosen by the owner.

Preferably, the service provided by the mobile phone 1 to the thief or the unauthorized person operates minimally.

For example, in the case where the mobile phone 1 works with a prepaid card, the mobile phone 1 indicates to the thief or to the person unauthorized that the account is zero. This assumes that the servers of management of the mobile phone account 1 have been warned, following the confirmation of the flight by the owner to the operator.

If, in another example, the mobile phone 1 operates according to a package, the mobile phone 1 displays a message "breakdown" to the thief or the unauthorized person.

Another example of understated service may also include non-access by the thief or unauthorized person to the directory and / or mobile phone owner's calendar 1. Mobile phone 1 indicates then blank files, as if no information was recorded. It is makes sure that any recording by the thief is done in another 2nd mobile phone memory partition 1. This new data is preserved in said memory and do not crush the previous ones.

The alarm message received by the server 3 allows the administrator the latter to prevent, either automatically or manually, following confirmation by the owner that his mobile phone 1 was stolen, the police or the authorized entity, that the mobile phone 1 has been stolen and that it is currently in a given geographical area. For legal reasons and confidentiality, the owner should never be informed of the place where finds his mobile phone stolen, unless the phone is in premises official objects ("found objects", "police stations", "agency of the operator "...) Only the competent and authorized authorities will be.

In case the stolen mobile phone 1 is moved by the thief or the unauthorized person, the alarm module 6 has the ability to locate with the different BTS 4 base stations he meets on his route. This location information is collected from a station controller basic BSC (not shown) which groups together several base stations 4 and defines geographical areas.

This location can be a GSM triangulation, process well known, or any other conventional tracking system using GSM networks, GPRS, UMTS, etc ... or other networks of terminals issuing a code identification on a short distance. These emitting terminals may be Bluetooth type, 802.11b or HomeRF, known as such.

Especially in the case where the network used for the localization is of the Bluetooth type, each transmitter terminal is provided with a chip or "Bluetooth" type integrated circuit as described in the patent application French No. 01 01527 in the name of the plaintiff.

• Il s'agit d'un prêt temporaire et dans ce cas, un tel prêt est de la responsabilité du propriétaire du téléphone mobile 1. Le propriétaire doit alors soit rester à proximité de l'utilisateur afin de maintenir désactivé le module d'alarme 6, soit prêter le porte-clés 7, soit autoriser l'utilisation d'un autre porte-clés ou équipement électronique comportant une puce Bluetooth, dont le code d'identification Bluetooth associé est enregistré dans la mémoire 6d du module d'alarme 6.
• il s'agit d'un voleur. Dans un tel cas, le voleur qui ne détient pas le porte-clès 7, finira bien par se trouver en dehors du rayon d'action du porte-clés 7, ce qui déclenchera l'activation du module d'alarme 6 de la façon décrite ci-dessus. Pour plus de sécurité, on peut même imaginer que le propriétaire puisse désactiver son porte-clés.

If the user is not usually authorized by the owner to use the mobile phone 1:

• This is a temporary loan and in this case, such a loan is the responsibility of the owner of the mobile phone 1. The owner must either stay close to the user in order to keep the alarm module deactivated. either lending the key fob 7 or authorizing the use of another key fob or electronic equipment including a Bluetooth chip, whose associated Bluetooth identification code is stored in the memory 6d of the alarm module 6.
• he is a thief. In such a case, the thief who does not hold the key holder 7, will eventually be outside the range of the key ring 7, which will trigger the activation of the alarm module 6 the way described above. For more security, we can even imagine that the owner can disable his keychain.

2nd case: the key ring 7 does not work or has been forgotten by the owner of the mobile phone 1

In this case, the transceiver 6a short distance from the phone mobile 1 can not receive an identification code from the key ring 7, whether or not the mobile phone 1 is within the range of the key ring 7. This has the effect of activating the alarm module 6 and triggering the sending of a alarm message by the transceiver 2b when using at least one service provided by the mobile phone 1.

If the legitimate owner uses the mobile phone 1, he is then taken for a thief.

• soit ne plus l'utiliser, jusqu'à récupération d'un porte-clés 7 en état de fonctionner normalement,
• soit désactiver le module d'alarme 6 en utilisant un protocole de sécurisation selon lequel le propriétaire doit taper sur le clavier de son téléphone mobile 1 :
  • soit un code dit « long » qui est différent du code PIN,
  • soit le premier code d'identification Bluetooth mémorisé dans la mémoire 6d du module d'alarme 6 suivi d'un code arbitrairement court (par exemple les derniers caractères du code « long »).

The fact that the mobile phone 1 no longer works as it is supposed to work, leads the owner to:

• or no longer use it, until recovery of a key ring 7 in a state of normal operation,
• either disable the alarm module 6 by using a security protocol according to which the owner must type on the keypad of his mobile phone 1:
  • a code called "long" which is different from the PIN code,
  • either the first Bluetooth identification code stored in the memory 6d of the alarm module 6 followed by an arbitrarily short code (eg the last characters of the code "long").

For the safety of the process automation, the disabled mode of alarm module 6 is only ensured for a period of maximum duration (1 hour for example). The duration of such a period is one of the parameters of operation of the service. Once the period has elapsed, the alarm module 6 is automatically reactivated. This cycle of operation ends when the keychain 7 works normally again.

3rd case: the alarm module 6 is deactivated and the owner of the mobile phone 1 (or the person using the mobile phone 1) away from the key ring 7.

In this case, during normal use of the mobile phone 1 (telephone conversation, data exchange, ...), the latter works with the alarm module 6 deactivated. As soon as the use has stopped, the alarm module 6 is activated. As soon as one of the features of the mobile phone 1 quoted previously used, the alarm module 6 is activated if it is in out of the range of the key ring 7, or otherwise is disabled. In case the alarm module remains activated, the legitimate owner will then be aware of the change of operation and act in consequence (return to the keychain or disable the alarm module according to the secure protocol).

• tous les codes d'identification Bluetooth habilités et sauvegardés dans la mémoire 6d du module d'alarme 6 ne peuvent être accessibles en clair (même par le propriétaire),
• tout nouveau code d'identification Bluetooth ne peut être sauvegardé qu'à travers la procédure de sécurisation mentionnée ci-dessus,
• les codes d'identification sauvegardés ne peuvent être effacés sans passage par le protocole de sécurisation mentionné ci-dessus,
• le protocole utilisant un code "long" est toujours une option possible à utiliser notamment en cas de perte, vol, oubli ou non-fonctionnement du porte-clés 7 (voir 2^ème et 3^ème cas cités ci-dessus),

• tout changement du code long ou du code court ne peut être effectué qu'après introduction soit du code long, soit du premier code d'identification Bluetooth suivi du code court,
• la sauvegarde du premier code d'identification Bluetooth est effectuée après sauvegarde du code long,
• un nouveau code d'identification Bluetooth peut devenir premier code d'identification, après introduction du code long,
• les codes d'identification de la ou des cartes SIM habilitées à être utilisées dans le téléphone mobile 1 sont sauvegardés dans la mémoire 2e du téléphone mobile 1,

It should also be noted that the detection of the theft of the mobile phone 1 is based on the fact that:

• all the Bluetooth identification codes authorized and saved in the 6d memory of the alarm module 6 can not be accessible in the clear (even by the owner),
• any new Bluetooth identification code can be saved only through the security procedure mentioned above,
• the saved identification codes can not be erased without passing through the security protocol mentioned above,
• protocol using a code "long" is always an option to use especially in case of loss, theft, neglect or non-functioning of key chains 7 (see 2 ^nd and 3 ^rd case cited above)
• a long code by default (included in the mobile phone 1 at purchase) is a series of zeros,
• any change in the long code or the short code can only be done after entering either the long code or the first Bluetooth identification code followed by the short code,
• the backup of the first Bluetooth identification code is performed after saving the long code,
• a new Bluetooth identification code can become the first identification code, after introduction of the long code,
• the identification codes of the SIM card (s) authorized to be used in the mobile telephone 1 are saved in the memory 2e of the mobile telephone 1,
• setting up an unauthorized SIM card necessarily leads to non-functioning of the mobile phone 1 (when the mobile phone 1 is turned on, a comparison is made between the identification code of the installed SIM card and the codes of the mobile phone 1 identification of authorized SIM cards).

We will now describe, with reference to FIG. 2A, a second mode of operation, or mode 1a, of the mobile phone 1 according to the invention

According to this second operating mode 1 bis, the key ring 7 is provided with an activation means, such as for example an on / off switch 7a (see Figure 1), that the owner of the mobile phone 1 operates at the closing so that the key ring 7 transmits towards the transceiver 6a of the alarm module 6 at least one Bluetooth identification code.

Note that this process is more suitable for issuers short-range receivers capable of providing two or more identification codes memorized by the owner, while, even though Bluetooth technology allows such a service, it is preferred that the identification code of the chip Bluetooth already exists (provided by the manufacturer), is unique, and is issued as soon as it there is a request by another Bluetooth device.

Alternatively, the switch of the key ring 7 could be replaced two push buttons connected respectively to two Bluetooth chips, these two chips each assigned a Bluetooth identification code, one of which corresponding to the activated mode of the alarm module 6, the other to the deactivated mode.

Following receipt of said identification code, its decoding by the decoder 6b and to its comparison with the identification code recorded in the 6d memory, the microcontroller 6c launches a test program provided that the mobile phone 1 is powered on. Such a test program is represented at Figure 3B.

This test program comprises a first test F, according to which the microcontroller checks whether the alarm module 6 is activated or not.

If the alarm module 6 is not activated, the mobile phone 1 works normally.

If the alarm module 6 is activated, the microcontroller 6c proceeds to a test G in which it checks whether the SIM card 2d has been changed.

If the SIM card 2d has not been changed, the microcontroller 6c performs one of the tests B and C mentioned previously.

If one of the tests, B or C is conclusive, the mobile phone 1 enters in a phase of delay during which it is still possible for the mobile phone owner to enter the Bluetooth identification code of disarming the alarm module 6. If the correct code is not entered, the alarm module 6 is activated and a minimized service takes place as it has has been described in the first embodiment 2A. If the issued code is recognized, the mobile phone goes into normal operation and the alarm module 6 is disabled.

If the 2d SIM card has been changed, the alarm module 6 remains enabled with a potential minimized use of its services as has been described in the first embodiment 2A. Thus, as soon as the use of at least a service provided by the mobile phone 1, the activation information of the module alarm 6 is then transmitted to the transceiver 2b of the mobile phone 1 which immediately sends an alarm message to the network of telecommunication 5 via the base station 4 with which he is in contact with the moment of module activation 6.

• les caractéristiques du téléphone mobile 1 tel qu'il était à l'origine, à savoir : le code d'identification de la précédente carte SIM, le numéro IMEI et le numéro d'identification d'abonné MSISDN,
• et les caractéristiques de la carte SIM nouvellement introduite.

In this message, are indicated advantageously:

• the characteristics of the mobile telephone 1 as it was originally, namely: the identification code of the previous SIM card, the IMEI number and the subscriber identification number MSISDN,
• and the features of the newly introduced SIM card.

Such a message is of course applicable to all modes of functioning which are described in the following description.

We will now describe, with reference to FIG. 2B, a second embodiment of the mobile phone 1 according to the invention.

This second embodiment is strictly identical to the first mode (1 or 1 bis) of realization apart from the fact that the SIM card 2d is fixed in the mobile phone 1 and, therefore, can not be changed by a thief or an unauthorized person. Such a phone may very well be "multicard SIM ", SIM cards other than the SIM card 2d being removable. In this case, the removal of one of the removable SIM cards is potentially a alarm stimulus. The non-mobility of the 2d SIM card can be easily detected by the thief. Such a characteristic can thus quickly dissuade the thief to use the mobile phone 1. The owner may then lose definitely the mobile phone 1. The thief will consider this as useless or dangerous and will be likely to throw it, (which is a lesser evil, because the mobile phone can be found) or to destroy it.

• de lancer une commande de blocage du téléphone mobile 1 qui ne pourra alors plus fonctionner,
• de chercher à localiser le voleur par la procédure de localisation décrite plus haut.

In the hope that the mobile phone 1 is kept by the thief or simply thrown away, the owner of the mobile phone 1 has the possibility:

• to launch a mobile phone lock command 1 which will then no longer work,
• to seek to locate the thief by the locating procedure described above.

As can be seen in FIG. 2B, a stimulus detector 10 is connected to the dialogue means 2 and the alarm module 6 via a switch I1. The detector 10 is also connected to the battery 8 by via a switch I2.

This switch I2 is in the closed position when automatically (mode 1) or voluntarily (mode 1a) the alarm module 6 is activated. He is in open position when the module 6 is inactivated. The detector 10 can not operate only when powered and the I2 switch controls this food. The detector 10 allows the mobile phone 1 to be sensitive to other stimuli than those previously mentioned in mode 1 or 1 bis (communication, battery charging, SIM change ...).

• un mouvement qui peut être détecté au moyen par exemple d'un petit mécanisme à balancier tel que par exemple du type mécanisme des montres automatiques, mais en beaucoup plus simple,
• de la lumière qui peut être détectée au moyen par exemple d'une petite cellule photosensible,
• un bruit qui peut être détecté au moyen par exemple d'un microphone,

et selon l'invention :

• une mise en charge de la batterie 8 qui peut être détectée au moyen par exemple d'un petit bouton qui serait pressé lors du positionnement du téléphone mobile 1 dans le chargeur de batterie,
• une mise en état de veille ou un état de fonctionnement (WAP, conversation) du téléphone mobile 1 qui peut être détecté(e) par des modifications d'intensité du courant ou de la tension dans le circuit.

As is apparent from the French patent application No. 01 12292 in the name of the applicant, such a detector 10 is able to be sensitive to:

• a movement that can be detected by means for example of a small balance mechanism such as for example the type of automatic watch mechanism, but much simpler,
• light that can be detected by means for example of a small photosensitive cell,
• a noise that can be detected by means for example of a microphone,

and according to the invention:

• a charging of the battery 8 which can be detected by means for example of a small button which would be pressed when positioning the mobile phone 1 in the battery charger,
• a standby state or a state of operation (WAP, conversation) of the mobile telephone 1 which can be detected by changes in the intensity of the current or voltage in the circuit.

• Une position ouverte (position par défaut) telle que représentée sur la figure 2B et qui indique que le détecteur 10 n'a détecté (avec I2 fermé : condition « sine qua non » de son fonctionnement) aucun stimulus (bruit, lumière , mouvement...) contrôlé normalement par lui. Quand l'interrupteur I2 est ouvert, l'interrupteur I1 est ouvert.
• Une position fermée, commandée par le détecteur de stimulus 10, suite à la détection, par ce dernier, d'un bruit, d'une lumière ou d'un mouvement. Une telle détection ne peut se faire que si l'interrupteur I2 est fermé de façon à ce que le détecteur de stimulus 10 soit alimenté. Lorsque tel est le cas, l'information de détection est émise en direction du module d'alarme 6 qui lance la procédure de sécurité telle que décrite à la figure 3B.

The switch I1 has two positions:

• An open position (default position) as shown in Figure 2B and which indicates that the detector 10 has detected (with I2 closed: condition "sine qua non" of its operation) no stimulus (noise, light, movement. ..) normally controlled by him. When the switch I2 is open, the switch I1 is open.
• A closed position, controlled by the stimulus detector 10, following the detection by the latter of a noise, a light or a movement. Such detection can be done only if the switch I2 is closed so that the stimulus detector 10 is powered. When this is the case, the detection information is sent to the alarm module 6 which initiates the security procedure as described in FIG. 3B.

• si le téléphone mobile 1 n'est pas sous tension, un circuit, matérialisé sur la figure 2B par une double flèche, permet d'alimenter tout ce qui est nécessaire à une mise en veille du téléphone mobile 1, sans alimenter la partie de ce dernier qui comprend le microphone, l'écouteur, l'écran, le vibreur et le clavier (non représentés). Dans cet état de veille particulier maintenu sur de courtes durées, selon une certaine périodicité, grâce à une minuterie (non représentée) intégrée dans le téléphone mobile 1, le téléphone mobile 1 peut se signaler auprès de chaque station de base 4 qu'il rencontre sur son parcours, ce qui a pour effet d'alimenter en informations la procédure de localisation décrite plus haut,
• si le téléphone mobile 1 est en état de veille normal ou en fonctionnement, la station de base 4 localise le téléphone mobile 1, ce qui a pour effet de lancer la procédure de localisation décrite plus haut au cours d'une période limitée par la minuterie.

Two situations are then to be considered in the case where the switch I1 is in the closed position (which implies the switch I2 closed and the reception of a stimulus: noise, light, movement):

• if the mobile phone 1 is not switched on, a circuit, shown in FIG. 2B by a double arrow, makes it possible to feed all that is necessary to put the mobile phone on standby 1, without feeding the part of this the latter which includes the microphone, the earpiece, the screen, the vibrator and the keyboard (not shown). In this particular state of standby maintained for short periods, according to a certain periodicity, thanks to a timer (not shown) integrated in the mobile phone 1, the mobile phone 1 can report to each base station 4 he encounters on its route, which has the effect of informing the location procedure described above,
• if the mobile telephone 1 is in normal standby state or in operation, the base station 4 locates the mobile phone 1, which has the effect of launching the locating procedure described above during a limited period by the timer .

In operating mode 1a, the alarm state could be also managed by a security program which was triggered by typing a code on the keypad of the mobile phone 1, following the launch a menu option managed by the mobile phone.

In the second embodiment of FIG. 2B and in the case where the state alarm would be controlled by such a program, it would be desirable for this program is launched at the request of the owner, the validation and taking into account of the activated or deactivated mode of the alarm module 6 being linked to the authentication of the owner by the introduction of his secret code.

The introduction of a correct secret code naturally leads to suppression of the sending of alarm messages by the transceiver 2b and the reopening of switch I2. However, to avoid sending messages alarm when the legitimate owner wants to disable alarm module 6, there is always has a gap of a few minutes between the detection of a stimulus and the signaling (sending alarm messages - localization) that such a stimulus has been detected. This shift of a few minutes, valid in all modes of operation of the mobile phone 1, of course does not intervene in the step of data protection as described in connection with the mobile phone 1 of Figure 2A.

Note that the detector 10 can, if desired, operate when the switch I2 is closed and the mobile phone 1 is off.

We will now describe, with reference to FIG. 2C, a third embodiment of the mobile phone 1 according to the invention.

The third embodiment differs from the previous ones in that that it comprises, in addition to the SIM card 2d, a second SIM card 2f which, unlike the 2d SIM card, is irremovable.

More precisely, the SIM card 2f is soldered on the electronic card (not shown) of the mobile phone 1, and possibly embedded in a immovable hood (any attempt to remove such a hood resulting in a malfunction of the mobile phone 1).

This SIM card is linked to the identification or subscriber number (different from the 2d SIM card) provided by the manufacturer of the phone mobile 1.

The only function of the SIM card 2f is to allow the execution of the "detection or theft" program of the mobile phone 1 by the module alarm 6.

The SIM card 2f thus enables the network 5 to locate the telephone Mobile 1 and to follow the security program accepted / defined by the owner: sending alarm messages, tracking and recording the next location a certain periodicity.

As can be seen in FIG. 2C, the SIM card 2d is connected to the battery 8 by an I3 switch that is likely to switch between a standby position (switch I3 in position F1) of the telephone mobile 1 operating with the SIM card 2d to a position in the off state of this latest. If the switch I3 is in position F1, the mobile phone 1 working with the SIM card 2d is idle, but the current does not pass anymore in the detector 10 '. When the switch I3 is in position F2, as well as shown in FIG. 2C, the current can flow in the detector 10 'and the mobile phone 1 running with the SIM card 2d is off. According to this third embodiment, the alarm module 6 can be activated only when the part of the mobile phone 1 that works with the 2d SIM card is at stop (switch I3 in position F2).

The SIM card 2f is, in turn, connected to the central unit 2a and controlled by two switches, I4 and I5.

The mobile telephone 1 according to the third embodiment presents the features of a normal mobile phone that has, in addition to the first embodiment above operating in mode 1 or 1bis, means software and hardware adapted so that the mobile phone 1 can alternatively operate with the SIM card 2d or the SIM card 2f with common basic elements.

These basic elements are in particular the antenna 2c, the transceiver 2b, the 2nd memory and the battery 8.

• à la batterie 8 par l'intermédiaire du commutateur I3 (quand le commutateur I3 est en position F2, le courant circule dans le détecteur 10' : le détecteur 10' fonctionne alors tandis que la partie du téléphone mobile 1 fonctionnant avec la SIM 2d est éteinte),
• à la carte SIM 2f par l'intermédiaire d'un interrupteur 14,
• et au module d'alarme 6 par l'intermédiaire d'un interrupteur I5.

As in the case of the second embodiment, the third embodiment comprises a stimulus detector 10 '. In the example shown, the detector 10 'is connected to:

• to the battery 8 via the switch I3 (when the switch I3 is in position F2, the current flows in the detector 10 ': the detector 10' then operates while the part of the mobile phone 1 operating with the SIM 2d is off)
• to the SIM card 2f via a switch 14,
• and to the alarm module 6 via a switch I5.

• une position fermée, dans laquelle le module d'alarme 6 est activé. Si dans cette position, la partie du téléphone mobile 1 utilisant la carte SIM 2d cesse de fonctionner (commutateur I3 en position F2), le courant circule dans le circuit matérialisé par la double flèche et le détecteur de stimulus 10' est alimenté. Le module d'alarme 6 et le détecteur 10' fonctionnent à l'unisson. Le passage de l'interrupteur I5, de cette position fermée à la position ouverte, que le commutateur I3 soit en position F1 ou F2, est toujours possible grâce au porte-clés 7, via l'émetteur-récepteur courte distance 6a,
• une position ouverte telle que représentée sur la figure 2C, dans laquelle le module d'alarme 6 est désactivé. Le passage de cette position à la position fermée n'est possible que lorsque la partie du téléphone mobile 1 utilisant la carte SIM 2d est en état de veille (sous tension ou commutateur I3 en position F1).

The switch I5 has two positions that are controlled according to the operating mode of the alarm module 6 (automatic procedure (mode 1) or commanded (mode 1 bis)). These positions are:

• a closed position, in which the alarm module 6 is activated. If in this position, the part of the mobile phone 1 using the SIM card 2d stops working (switch I3 in position F2), the current flows in the circuit materialized by the double arrow and the stimulus detector 10 'is powered. The alarm module 6 and the detector 10 'operate in unison. The passage of the switch I5, from this closed position to the open position, that the switch I3 is in position F1 or F2, is still possible thanks to the key ring 7, via the short-distance transceiver 6a,
• an open position as shown in Figure 2C, in which the alarm module 6 is disabled. The transition from this position to the closed position is only possible when the part of the mobile phone 1 using the SIM card 2d is in the standby state (under voltage or switch I3 in position F1).

As described with reference to FIG. 2B, such a detector 10 'is suitable to be sensitive to movement, light, noise, charging battery 8, but not to a standby state or an operating state (WAP, conversation) of the mobile phone 1.

The stimulus detector is, in this example, also suitable for detect a 2d SIM card change. For this purpose, the microcontroller 6c compares the subscriber number assigned to the SIM card introduced in place of the SIM card 2d and the subscriber number assigned to the mobile phone 1 which is registered in a portion of the memory 6d reserved to the stimulus detector 10 '. Such a comparison may alternatively be automatically performed when the mobile phone is started 1.

This storage possibility allows the transceiver 2b, when the part of the mobile phone 1 using the SIM card 2f is activated, to send to the server 3 a message of the SMS type which contains the number subscriber assigned to the SIM card 2d. If such a number is the owner's number, the account can be blocked, forcing the thief to change SIM card, and therefore of number, and thus avoid the legitimate owner unnecessary expenses. Once the SIM card has been changed, the new owner will be perhaps know the operator by complaining about the malfunction of the mobile phone 1 (for example mobile phone lock 1 if the thief has introduces a new SIM card instead of the SIM card 2d). But maybe that the owner will also want to use the ability to locate his robber by the locating procedure described above.

The stimulus detector 10 ', which controls the closing (switch 14) of the power supply circuit of the part of the mobile phone 1 using the card SIM 2f, only works when the part of the mobile phone 1 running with the SIM card 2d is not turned on.

• une position ouverte telle que représentée sur la figure 2C, qui correspond à la non détection par le détecteur 10' du moindre stimulus contrôlé par lui. Cette position ouverte est la position par défaut,
• une position fermée qui correspond à la détection d'un stimulus (autre que le changement de carte SIM 2d) par le détecteur de stimulus 10', à condition que le commutateur I3 soit en position F2, de façon à ce que le détecteur de stimulus 10' soit alimenté. Lorsque tel est le cas, seule la partie du téléphone mobile 1 utilisant la carte SIM 2f est alimentée (si interrupteur I5 est fermé). L'information de détection, si l'interrupteur I5 est fermé, est émise en direction du module d'alarme 6 qui lance la procédure de sécurité telle que décrite à la figure 3A ou 3B, à laquelle sont ajoutés les tests non représentés correspondant aux stimuli détectés par le détecteur 10'.

The switch I4 has two positions:

• an open position as shown in Figure 2C, which corresponds to the non detection by the detector 10 'of any stimulus controlled by him. This open position is the default position,
• a closed position which corresponds to the detection of a stimulus (other than the SIM card change 2d) by the stimulus detector 10 ', provided that the switch I3 is in position F2, so that the stimulus detector 10 'is powered. When this is the case, only the part of the mobile phone 1 using the SIM card 2f is powered (if switch I5 is closed). The detection information, if the switch I5 is closed, is sent towards the alarm module 6 which initiates the security procedure as described in FIG. 3A or 3B, to which are added the unrepresented tests corresponding to the stimuli detected by the detector 10 '.

In some cases, it might be helpful if, when the legitimate owner wants to disable the alarm module 6, the stimulus detector 10 'does not work immediately by closing the switch I4 after detection of a stimulus. All that is required is that a timer (not shown) triggers the delayed closing of the switch I4 after detection of the stimulus. Few minutes of delay, before putting the phone part mobile 1 using the SIM card 2f and launching the security procedure, should allow the owner to turn on the mobile phone 1, so the standby, and thus switch the switch I3 to position F1, which has to stop the alarm process.

We will now describe with reference to FIG. embodiment of the mobile phone 1 according to the invention.

As in the previous example, the fourth embodiment includes, in addition to the SIM card 2d, a second SIM card 2g similar in all points to the SIM card 2f.

As can be seen in Figure 2D, the SIM card 2d is connected directly to the battery 8. The SIM card 2g is connected directly to the central unit 2a.

• à la batterie 8 par l'intermédiaire de l'interrupteur 16,
• à l'unité centrale 2a et à la carte SIM 2g par l'intermédiaire d'un commutateur I7.

The fourth embodiment also comprises a stimulus detector 10 "which is connected to:

• to the battery 8 via the switch 16,
• to the central unit 2a and the SIM card 2g via an I7 switch.

Such a circuit configuration allows the 10 "stimulus detector function, whether the mobile phone 1 is at a standstill or in a standby state. So, at any time, the mobile phone 1 has the possibility to signal a non desired, whether it is a simple manipulation without waking or passage of any communication.

Said configuration is more energy consuming than that of the third embodiment.

It furthermore supposes the possibility of alternating operation of the part of the mobile phone 1 using the 2g SIM card and part of the phone mobile 1 using the SIM card 2d, when both parties are in the standby state. This technical possibility of alternation depends on the number of basic elements allocated to the part of the mobile phone 1 using the 2g SIM card and totally independent of the part of the mobile phone 1 using the SIM card 2d.

In the example of FIG. 2D, the detector 10 "is able to be sensitive to movement, light, noise, charging of the battery 8, a standby state or an operating state (WAP, conversation) of the mobile phone 1.

The stimulus detector 10 "is, in this example, also suitable for detect a 2d SIM card change in the same way as the 10 'detector of the third embodiment.

• une position fermée, dans laquelle le module d'alarme 6 est activé et dans laquelle le détecteur de stimulus 10" est alimenté. Le moindre stimulus ferme le circuit d'alimentation de la carte SIM 2g grâce au commutateur I7 qui se trouve alors automatiquement mis en position P1. Trois cas se présentent alors:
  • la partie du téléphone mobile 1 utilisant la carte SIM 2d est éteinte. Le programme de sécurité (envoi de messages d'alarmes, localisation...) démarre alors dès la mise en état de veille de la partie du téléphone mobile 1 utilisant la carte SIM 2g, ce qui correspond à la position P1 du commutateur 17.
  • Les parties respectives du téléphone mobile 1 utilisant la carte SIM 2d et la carte SIM 2g sont toutes deux en état de veille. La mise en état de veille de la carte SIM 2g correspond à la position P1 du commutateur I7, donc à la détection d'un vol (stimulus détecté). Il est alors fondamental que la partie du téléphone mobile 1 utilisant la carte SIM 2g se localise au moins une fois auprès de la station de base 4 et que la partie du téléphone mobile 1 utilisant la carte SIM 2d continue à bien fonctionner. Du fait que le circuit d'alimentation de la carte SIM 2g reste fermé après détection de stimulus pendant une certaine durée, grâce à une minuterie (non représentée), on peut imaginer qu'un programme de traitement de l'information détourne certains éléments d'information recueillis durant la communication avec la carte SIM 2d, comme le numéro de l'appelant, des noms de personnes ou de lieux et/ou des bruits d'environnement (s'il est possible de les reconnaítre et enregistrer), ces éléments d'informations étant ensuite envoyés par la carte SIM 2g à l'arrêt de la communication avec la carte SIM 2d, lorsque cela sera rendu possible.
  • la partie du téléphone mobile 1 utilisant la carte SIM 2g est en état de veille (commutateur I7 en position P1, vol détecté) et la partie du téléphone mobile 1 utilisant la carte SIM 2d en fonctionnement (communication en cours réalisée par le voleur...). La minuterie décomptant le temps imparti à la période de veille pour la partie du téléphone mobile 1 utilisant la carte SIM 2g est arrêtée dès que la partie du téléphone mobile 1 utilisant la carte SIM 2d commence à fonctionner, l'interrupteur I7 passant alors en positon P2 (le courant circule uniquement dans le détecteur de stimulus 10"). Dès que la partie du téléphone mobile 1 utilisant la carte SIM 2d cesse de fonctionner, la minuterie est redémarrée, et l'interrupteur I7 repasse en position P1, pour la durée restante.
• une position ouverte telle que représentée sur la figure 2D, dans laquelle le module d'alarme 6 est désactivé.

The switch I6 has two positions:

• a closed position, in which the alarm module 6 is activated and in which the stimulus detector 10 "is energized The least stimulus closes the power supply circuit of the SIM card 2g thanks to the switch I7 which is then automatically set in position P1, there are three cases:
  • the part of the mobile phone 1 using the SIM card 2d is off. The security program (sending alarm messages, localization, etc.) then starts as soon as the part of the mobile telephone 1 using the SIM card 2g is placed in standby state, which corresponds to the position P1 of the switch 17.
  • The respective parts of the mobile phone 1 using the SIM card 2d and the SIM card 2g are both in the standby state. The standby state of the SIM card 2g corresponds to the position P1 of the switch I7, thus to the detection of a flight (stimulus detected). It is therefore essential that the part of the mobile phone 1 using the SIM card 2g is located at least once at the base station 4 and that the part of the mobile phone 1 using the SIM card 2d continues to work well. Since the power supply circuit of the SIM card 2g remains closed after detection of stimulus for a certain period of time, thanks to a timer (not shown), it is conceivable that an information processing program diverts certain elements of the data. information collected during the communication with the SIM card 2d, such as the caller's number, names of persons or places and / or environmental noise (if they can be recognized and recorded), these elements information is then sent by the SIM card 2g to stop communication with the SIM card 2d, when this will be made possible.
  • the part of the mobile phone 1 using the SIM card 2g is in the standby state (switch I7 in position P1, theft detected) and the part of the mobile phone 1 using the SIM card 2d in operation (communication in progress carried out by the thief .. .). The timer counting down the time allotted to the idle period for the part of the mobile phone 1 using the SIM card 2g is stopped as soon as the part of the mobile phone 1 using the SIM card 2d starts to work, the switch I7 then going into position P2 (the current flows only in the stimulus detector 10 ") As soon as the part of the mobile phone 1 using the SIM card 2d stops working, the timer is restarted, and the switch I7 goes back to position P1, for the duration remaining.
• an open position as shown in Figure 2D, wherein the alarm module 6 is disabled.

• une position P1 telle que représentée sur la figure 2D et dans laquelle le détecteur de stimulus 10", activé (interrupteur I6 en position fermée), a détecté un stimulus quelconque. Pour des raisons de confort, le lancement du programme de sécurité (envoi de messages d'alarme, localisation...) peut être légèrement retardé, afin de permettre au légitime propriétaire de faire passer le module d'alarme 6 à l'état désactivé.
• et une position P2 dans laquelle le courant circule dans le détecteur 10" mais pas dans la carte SIM 2g. Il s'agit de la position par défaut.. Dans tous les cas, la position P1 de l'interrupteur I7 est reprise après une certaine durée, et seule la détection d'un nouveau stimulus sera apte à déclencher le programme de sécurité,

The I7 switch has two positions:

• a position P1 as shown in Figure 2D and in which the stimulus detector 10 ", activated (switch I6 in the closed position), has detected any stimulus.For reasons of comfort, the launch of the safety program (sending of alarm messages, location ...) may be slightly delayed, to allow the legitimate owner to switch the alarm module 6 to the deactivated state.
• and a position P2 in which the current flows in the detector 10 "but not in the SIM card 2g.It is the default position .. In all cases, the position P1 of the switch I7 is resumed after a certain duration, and only the detection of a new stimulus will be able to trigger the security program,

It goes without saying that the embodiments that have been described above have been given for information only and in no way limitative, and that many modifications can be easily made by those skilled in the art without departing from the scope of the invention.

• il serait possible d'inverser la logique du principe de fonctionnement du téléphone mobile 1 qui consiste à envoyer des messages d'alarme uniquement lorsque le détecteur de stimulus et/ou le porte-clés 7 ont détecté une anomalie. En effet le téléphone mobile 1 pourrait envoyer des messages (SMS par exemple) de type " RAS tout va bien" à intervalles réguliers (un message par semaine ou un message tous les trois jours par exemple) au serveur 3. Par contre lorsque le téléphone mobile 1 est volé et la carte SIM 2d enlevée, le serveur 3 ne recevant plus de messages en déduira un fonctionnement anormal du téléphone mobile 1 et alertera le propriétaire.
• il serait également possible, voire même préférable, que le module d'alarme 6, tant du point de vue logiciel que du point de vue matériel, soit directement intégré par les industriels dès la fabrication du téléphone mobile 1, de façon à éviter l'ajout d'une deuxième carte SIM inamovible. Ceci permet de s'affranchir du cas où le voleur ou la personne non autorisée jette la carte SIM après avoir dérobé le téléphone et en utilise une autre n'ayant pas l'application antivol. Pour faire le lien avec l'abonné victime du vol, il faut alors transmettre le numéro international de téléphone mobile (IMEI) dans le message d'alarme afin d'identifier ce téléphone comme lui appartenant. Ceci impose bien sûr de gérer quelque part une table de correspondance entre l'IMEI et le numéro d'identification d'abonné MSISDN.

Therefore :

• it would be possible to reverse the logic of the principle of operation of the mobile phone 1 which is to send alarm messages only when the stimulus detector and / or the key ring 7 have detected an anomaly. Indeed the mobile phone 1 could send messages (SMS for example) type "RAS everything is fine" at regular intervals (one message per week or a message every three days for example) to the server 3. By cons when the phone mobile 1 is stolen and the SIM card 2d removed, the server 3 no longer receiving messages will infer an abnormal operation of the mobile phone 1 and alert the owner.
• it would also be possible, or even preferable, that the alarm module 6, both from a software point of view and from a hardware point of view, be directly integrated by the manufacturers as soon as the mobile phone 1 is manufactured, so as to avoid the adding a second non-removable SIM card. This eliminates the case where the thief or the unauthorized person throws the SIM card after stealing the phone and uses another without the anti-theft application. To make the link with the subscriber victim of the theft, it is then necessary to transmit the international mobile number (IMEI) in the alarm message to identify this phone as belonging to him. This of course makes it necessary to manage somewhere a correspondence table between the IMEI and the subscriber identification number MSISDN.

We can also imagine that there is, in each of the modes of previously described, a counter that allows to launch the safety program only when a certain number, to be defined, of different or identical stimuli have been accounted for, in order to avoid the unwanted launch of such a program. Indeed it can happen that the owner himself puts himself in a situation where the mobile phone 1 could wrongly take him for a thief.

• Tout téléphone mobile avec antivol peut être une combinaison raisonnée des quatre modes de réalisation qui viennent d'être décrits ci-dessus, tout particulièrement si l'on considère la possibilité d'intégrer, pour l'un quelconque des trois derniers modes de réalisation représentés respectivement sur les figures 2B, 2C et 2D, les deux processus de mise en alarme mis en oeuvre dans les premiers modes de réalisation (1 et 1 bis) représentés sur la figure 2A.
• Pour l'un quelconque de ces quatre modes de réalisation, lorsque le module d'alarme 6 n'est pas activé, on peut imaginer que la non détection d'un stimulus particulier pendant une certaine période de temps (1/2 h, 1 heure ou autres), permette de fermer le circuit d'alimentation du téléphone. Ce dernier étant éteint, il n'utilisera plus sa batterie 8. Si l'on admet qu'un téléphone mobile peut ne pas être utilisé pendant les heures de repas et de sommeil, le non déclenchement du détecteur de stimulus « mouvement » pourrait permettre de doubler l'autonomie du téléphone mobile 1. L'apparition d'un tel stimulus remettrait naturellement en veille le téléphone mobile 1, si celui-ci s'est trouvé arrêté du fait de l'absence de détection de ce stimulus.
• Un tel téléphone mobile 1, lorsque son module d'alarme 6 est activé, peut servir de base d'information à distance : le stimulus pouvant être la montée dangereuse des eaux d'une rivière ou d'un lac, le bruit des tirs de fusil dans une zone où la chasse est interdite, un début d'incendie ou un niveau de chaleur trop élevé dans un lieu isolé.... Le calibrage des stimuli d'un type donné permet d'établir une correspondance avec les différents niveaux possible d'urgence de l'appel : « niveau de chaleur suspect... Zone à surveiller » « plus de 100°, intervention urgente sollicitée » « intervention prioritaire, risque d'incendie »....

Finally, whatever the type of process used to make the phone with antitheft according to the invention, it is of course possible to imagine that such a phone can be used as a lure and thus be left by the owner, at home or in his home. vehicle or at his desk, hoping that in case of theft, the thief leaves with him. If it is very difficult to track stolen jewelry or banknotes, it is reasonably easy to track the thief who took such a device.

• Any mobile phone with theft can be a reasoned combination of the four embodiments described above, especially if one considers the possibility of integrating, for any one of the last three embodiments represented respectively in Figures 2B, 2C and 2D, the two alarm processes implemented in the first embodiments (1 and 1a) shown in Figure 2A.
• For any of these four embodiments, when the alarm module 6 is not activated, it can be imagined that the non-detection of a particular stimulus for a certain period of time (1/2 h, 1 time or other), allows to close the power supply of the phone. The latter being off, he will no longer use his battery 8. If it is accepted that a mobile phone may not be used during meal and sleep hours, the non-triggering of the stimulus detector "movement" could allow to double the autonomy of the mobile phone 1. The appearance of such a stimulus would naturally return to sleep mobile phone 1, if it was stopped because of the lack of detection of this stimulus.
• Such a mobile phone 1, when its alarm module 6 is activated, can serve as a remote information base: the stimulus may be the dangerous rise of the waters of a river or lake, the sound of fire from rifle in an area where hunting is forbidden, a start of fire or a level of heat too high in an isolated place .... Calibration of stimuli of a given type makes it possible to establish a correspondence with the various possible levels emergency call: "suspected heat level ... Area to be monitored""more than 100 °, urgent intervention requested""priority intervention, fire hazard" ....
