Abstract

The present invention provides a security system for admitting a user (101), having a standard cellular telephone (104), into, or allowing a user to visit, a security area. Said security system being flexible, supporting multiple users each having a unique standard cellular telephone and possibly multiple locks individually responsive to each standard cellular telephone.

Description

SECURITY SYSTEM FOR ADMITTING A USER HAVING A CELLULAR PHONE TO VISIT A SECURITY AREA
TECHNICAL FIELD OF INVENTION
The present invention relates in generally to a security system for admitting a user to visit a security area, and more specifically, to a security system for admitting a user using a standard cellular phone.
DESCRIPTION OF RELATED ART
In cellular telecommunication systems cellular telephones are equipped with a hardware code uniquely identifying each phone to the system. Such a code is for instance called IMEI code in the GSM system. If a owner to a cellular phone for some reason loses his phone, for instance due to theft, he may prohibit the thief or someone else from using his phone by reporting it as stolen to the telecommunication operator. Not only will his specific telephone account be closed but his specific telephone will also be useless, since the unique IMEI code is placed on a blacklist and the telephone system will refuse to connect calls using hardware which is present at the blacklist.
Thus, has each cellular telephone a unique number which uniquely identifies the specific telephone.
Different sorts of electronic keys are known, such as for instance radio keys used to open garage doors. Such radio keys may comprise a identification code, which is sent when a user press a button, and which is identified by a receiver opening the garage door. Such radio keys are somewhat expensive to produce and are not very flexible in their application. For instance can it be cumbersome to handle several different doors and several different users. It would therefore be beneficial if a more flexible security system could be achieved for admitting a user to a security area where several different persons have, or do not have, access to different security areas through several different locked doors.
SUMMARY OF INVENTION
The object of the present invention is thus to provide a security system for admitting a user, having a standard cellular telephone, into, or allowing a user to visit, a security area. Said security system being flexible, supporting multiple users each having a unique cellular telephone and possibly multiple locks individually responsive to each cellular telephone.
The objects of the present invention, described above, are obtained by providing a system according to claim 1.
An advantage of the present invention is that a flexible security system is achieved which uses standard cellular telephones as electronic radio keys.
Another advantage is that the security system may control a door for admitting a user to enter a specific area, or may with regular intervals check if a user is present in a specific area.
Another advantage with the present invention is that a security system with high flexibility and good security is achieved with very low-cost means.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the scope of the invention will become apparent to those skilled in the art from this detailed description.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention and wherein
Figure 1 shows a diagrammatic view of a preferred embodiment according to the present invention;
Figure 2 shows a schematic block diagram of a preferred embodiment according to the present invention;
Figure 3 shows a schematic block diagram of another preferred embodiment according to the present invention;
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
In figure 1 a user 101 is approaching a door 102 leading to a security area. It shall be understood that the term security area is used, in the present text, in a very broad sense. It may thus not necessarily indicate an area with extremely high security requirements, though such areas are of course included, but may also include any area behind a locked door, such any ordinary housing.
Said user 101 has a standard cellular telephone 104, in this preferred embodiment a GSM telephone, though any standard cellular telephone comprising a unique hardware code may be used, which, upon request, or on a regular basis, sends a IMEI message. This IMEI message is received by a security apparatus
103 being connected to the locking function of said door 102. The security apparatus 103 may be designed, or tuned, to only receive signals which are sent within a specified area from said security apparatus 103, so that distant cellular telephones, sending IMEI messages, do not affect the locking function of the door 102. The function of said security apparatus 103 are more detailed in figure 2.
Figure 2 shows a schematic block diagram of the security apparatus shows in figure 1. The standard cellular telephone
104 sends a IMEI message which is received by a broadband receiver 201 comprising an antenna 202. The broadband receiver is broadband in terms of receiving the complete GSM band. In another preferred embodiment the broadband receiver may be designed to receive a much wider band, or several separated bands, such as both the GSM and the PCN band. The messages received by the broadband receiver is forwarded to a GSM message decoder 203. The GSM message decoder is designed only for recognising a GSM IMEI message and may therefore be a relatively low-cost implementation. Connected to the GSM message decoder 203 is an I/O ( input/output ) device 204 for storing, retrieving and deleting records in a register 205 located in the GSM message decoder. The I/O device 204 is used to store IMEI codes in the register 205. When a IMEI message is received and decoded it is compared with the stored IMEI codes, and if a match occur, that is if the decoded IMEI is present in the stored set of IMEIs, the GSM decoder signals to a validating device 206 which unlocks the door 102 admitting the user 101 access to the security area behind the door 102. In another preferred embodiment the storing of IMEI codes may be performed through the radio interface, comprising the broadband receiver 201. In this case the GSM message decoder is also arranged to receive digits, as well as instructions for storing a sequence of digits in said register 205.
Figure 3 shows another preferred embodiment according to the invention, where the security apparatus comprises a transmitting device 301 coupled to the antenna 202 and the GSM message decoder 203. With this arrangement the security apparatus may send a message to cellular phones within reach requesting transmission of the IMEI code.
The security apparatus may also fetch other data from the cellular phone such as the telephone number of a telephone subscription installed in said phone, a digit sequence entered on the cellular phone by said user, or other types of information which may be combined with the IMEI for increased security.
According to yet another preferred embodiment the security apparatus may be mounted in a corridor or in a room for surveillance purposes. It may then transmit an alarm signal to a security service or may sound an alarm if a non-authorised person is visiting the room or corridor.
