Description

1 Introduction

Secure GSM mobile phone locking and switching system (GSM Global System for Mobile Communication)

The invention belongs to the technical field of electrical engineering and the subclass telephone systems in conjunction with other electrical systems.

On the market, there are mechanical and electro-mechanical locking systems for closing objects, such. As of doors, cabinets and electrical switching systems for switching electrical systems. These systems are supported by various security systems and the like. a. Radio remote controls, numeric code, card, day and biometric systems controlled.

Another new security system for controlling the systems is a secure GSM mobile phone closing / switching system with electrical contacts / relays.

Electro-mechanical locking systems and electrical switching systems are switched by a secure GSM mobile phone closing / switching system (referred to below as GSM key system module). The GSM KeySystem module includes a GSM mobile device that receives and evaluates calls and messages from mobile devices and generates an electrical signal based on the results. The module sends back information about actions on the module to the mobile devices of the caller and the KeySystem administrator. The module, authorized phone numbers and other parameters are managed by the KeySystem administrator.

2 Functional principle GSM-KeySystem module

2.1 Technical preparation

The switching of locking / switching systems with the help of mobile radio is implemented in the core by the GSM KeySystem module. The GSM KeySystem module consists of a GSM mobile radio unit with antenna, unlocked SIM card with mobile phone number, GSM KeySystem module software application (hereinafter KMSA) and electrical contacts or a relay, in turn, via electrical contacts with the electro-mechanical locking system or the electrical switchgear is connected. Mobile reception is required. Keyboard and display are not necessary. Relay can z. B. switching or sensing relay.

Power is supplied by an external power supply. The external power supply may be a permanent power source or a solar or wind turbine. The bridging of temporary power failures can be realized by the use of a battery.

In the GSM KeySystem module, the phone numbers authorized for closing / switching are stored on the SIM card or in the additional memory. In addition to the phone number, other details such as password, authorization periods and other phone numbers can be stored.

The data is managed by the KeySystem administrator. One or more administrators can manage the GSM KeySystem module. The administration of the groups and call numbers can either directly on the module or z. B. via an administrator KeySystem software application. The data is then transmitted by the administrator by means of a message or via a mobile connection to the GSM KeySystem module. The KeySystem module software application manages the data and performs the actions and checks and initiates an electrical signal. Via the electrical contacts or a relay on the GSM-KeySystem module, the connection to the closing and switching system is realized.

2.2 Positive closing / switching operation - authorized call

An initiator wants to close an object. He calls with the help of a GSM mobile device (eg mobile phone, smartphone, computer) the known number of the GSM KeySystem module. The module reads during call setup the phone number of the calling mobile device. It will call the caller's number (cailing party number in the SETUP Message Layer 3 OSI model, Standard ITU Q.931 ) checked. The check shows that the number is a legitimate number. Optionally, further parameters can be checked. If these parameters are also correct, we will generate an electrical signal from the module z. B. the relay switches. The relay is connected to the electrical system and z. B. the object is unlocked or an electrical device is turned on.

Optional: In addition to this. the GSM KeySystem module requests a password eg. For example, use a USER INFORMATION message to send the initiator's mobile device. The initiator uses an authorized user software application to enter the password on the mobile device and send it back to the GSM KeySystem module. There the password is checked. If the password and the phone number are authorized, the GSM KeySystem module sends a signal to the electrical system.

The attempt of establishing a connection between the mobile radio of the initiator and the GSM KeySystem module by the GSM KeySystem module after a specified time, for. B. two seconds, ended. Information about the successful operation is sent to the initiator's mobile device.

Immediately afterwards, the GSM key system module can send to the GSM mobile device of the administrator a connection setup attempt with the information about the positive closing process. This information is sent in the message. The information includes the positive closing process, the date, time and phone number of the initiator's mobile device. The connection attempt is after a very short time, z. B. two seconds, terminated by the GSM KeySystem module.

2.3 Negative closing / switching operation - unauthorized call

An initiator wants to unlock an object. He does not belong to a legitimate group. He calls with the help of a GSM mobile device and the number of the module to the GSM KeySystem module. The system checks the call number of the calling mobile device during connection setup. The calling number of the caller (calling party number in the SETUP message) is checked. The number does not belong to a legitimate group and is therefore not a legitimate number. The GSM KeySystem module does not send a signal to the electrical system. The same process also applies to a suppressed phone number.

Alternatively: The phone number has been verified as authorized and now the GSM KeySystem module sends a password request to the initiator's mobile device. The initiator enters an incorrect password on the mobile device and sends it back to the GSM KeySystem module. There it is checked. The password is wrong even though the phone number is authorized. The GSM KeySystem module does not send a signal to the electrical system.

The attempt to establish a connection between the initiator's mobile device and the GSM key system module is initiated by the GSM key system module after a specified time, for 10 seconds, rejected. This is an information z. As "user not responding" or "unassigned number", suppressed phone number in the SETUP message sent to the mobile device of the initiator. In addition, a call forwarding to another phone number, z. To those of the KeySystem administrator. This can then identify the unauthorized caller.

After the termination of the attempt to establish a connection between the mobile device and the GSM KeySystem module, the module sends information to the KeySystem administrator about the negative process. This information includes the "Unauthorized Call" process, the date, time and, if present, the phone number of the initiator's mobile device. To transfer the information, a connection to the administrator is initiated. In the SETUP message, the information is transmitted and the connection attempt is made after a time, for. B. two seconds or after receiving z. B. the ALERTING message, terminated by the GSM KeySystem module.

2.4 Safety

Security is ensured by checking the caller's number in the GSM KeySystem module. The phone number is loud ITU standard Q.931 (Note: GSM uses Layer 3 - Network Layer Parameters of ISDN) as the "calling party number" parameter in the "SETUP message" when connecting from the initiator's mobile device to the GSM KeySystem module. The parameter is evaluated in the GSM KeySystem module. The number of the mobile device is verified in the network registration in the GSM mobile network of the mobile network operator (eg., Telekom, Vodafone) in the "Home Location Register" (HLR). In addition, the telephone number is verified during the connection setup in the "Operation and Maintenance Center" (OMC) of the network operator and corrected if necessary.

In addition, security can be increased by password prompting, other authorized phone numbers that must call the GSM KeySystem module within a defined period of time, and time restrictions. The GSM KeySystem module software application handles these solutions.

The method of closing by multiple callers (key group) is the same as that of the individual caller, however, the callers of the key group must be in a set period of time, e.g. B. 120 seconds, successfully call and have been checked. The GSM KeySystem module can then either initiate an electrical signal after checking a portion of the key group or only after the entire key group has been successfully tested.

The KeySystem administrator is informed about every action on the module by the GSM KeySystem module. Thus it monitors the GSM KeySystem module and can block the module at any time from any location, assuming mobile reception. In the locked state, only use by the administrator or mechanical closure is possible.

3 GSM KeySystem Module Software Application (KMSA)

3.1 Introduction

The authorized telephone numbers are stored in the GSM KeySystem module. The phone numbers and parameters are stored in the memory of the module (memory on SIM card or additional data memory). The management of the data, connections, messages, etc. is realized by the KMSA. The program is programmed in Java and preinstalled on the mobile unit in the GSM KeySystem module. The KeySystem administrator can perform software updates.

The software starts the mobile radio until it is ready to receive status (automatic PIN entry), receives calls and messages, reads values from the mobile unit and the data memory, checks the values, triggers electrical closing / switching operations if successful, and initiates responses and forwardings. It manages the data store.

3.2 Functions KMSA

3.2.1 Introduction

The functions describe the management of data, connections, messages, etc. between the GSM KeySystem module and the mobile devices. Data is stored in the data memory. It is the main component of the GSM KeySystem module. It stores two types of data, the ADMIN and KEY data. Values are passed through the separator,; ' separated. The data is ended with the character '#'.

3.2.2 Initialize data memory

1

IMEI ≙ 15 stellige Seriennummer der Mobilfunkeinheit; International Mobile Station Equipment Identity

]; [SIM-Kartennummer2

2

SIM-Kartennummer ≙ 20 stellige Nummer, Subscriber Identity Module

]; [Administrator Rufnummer](; weitere Administrator Rufnummern)#The GSM-KeySystem module is factory-installed only with the KMSA. Calls and messages are always evaluated but rejected and deleted. For the module to become operational, an initialization is necessary. This is done by the initialization message. The KeySystem administrator uses the mobile radio to send a message to the GSM KeySystem module with the following content and format:
INITIAL; [IMEI number 1

1

IMEI ≙ 15 digit serial number of the mobile unit; International Mobile Station Equipment Identity

]; [SIM card number 2

2

SIM card number ≙ 20 digit number, Subscriber Identity Module

]; [Administrator number] (further administrator numbers) #

The IMEI and SIM card numbers are stored in the system of the mobile radio unit in the GSM KeySystem module and should only be known to the administrator.

Function KMSA:

KMSA receives the message, reads the message, compares the values IMEI number, SIM card number with the local values and checks the number of the sender of the message with the specified number of the administrator. If all values are correct, the data in the data store will be:
ADMIN; [Number] (call number)
written. Thereafter, the message is automatically deleted.

Optional: Another administrator can, for example, B. by another [phone number of the administrator] to be set up. Then only one administrator phone number must match the sender of the message during the check.

Optional: Before the phone number of the ADMIN is written to the data memory, any possible contents of the data memory are completely deleted. This ensures that only the sent ADMIN data is in the data memory after initialization.

After initialization, the KeySystem administrator can already switch the module. Now the administrator can create the keys. The administrator telephone number is used to evaluate messages and to process the contents, to send information about events on the GSM KeySystem module from the module to the mobile device of the administrator or to initiate call forwarding to the administrator in the event of an unauthorized call.

3.2.3 Authorized telephone numbers (keys) in the data memory

The authorized telephone numbers are stored in the data memory of the GSM KeySystem module. Since additional parameters for the authorization check can be added to the authorized number, this is called the key. The data is stored as an authorized key (KEY). The key may include one or more phone numbers and other parameters. Due to the fact that several numbers can occur in the key, one parameter is the check number in the key. The number of checks, values from 1-9, determines how many of the numbers in the key must be successfully checked within a test period. The test duration parameter is specified in seconds in the key. In addition, passwords can be assigned to the individual numbers. Furthermore, keys can receive authorization periods. Ie. the authorized telephone numbers are only authorized within the period. Empty data fields, except mandatory fields, are not limiting.

The key must or can contain the following parameters. parameter description Required field KEY Identifier of a key Yes ; separators Yes, between parameters # End of the data of a key Yes, at the end of a key Test number (1-9) Number of necessary phone numbers for a legitimate operation Yes Max. Test duration in seconds [1-999] maximum period for checking authorized telephone numbers.

4 user interfaces / software applications

The GSM KeySystem module is operated by the KeySystem administrator and the authorized users via mobile devices. The following describes the applications for operation by the Authorized User and KeySystem Administrator of the module.

4.1 Authorized User Software Application (BBSA)

Basically, it is possible in the simplest case to switch the GSM KeySystem module by calling a mobile device with an authorized number. However, this can lead to incorrect operation and represents a security risk of the mobile device in case of unwanted or unauthorized use by other people. Thus, there is a need to use a special software application, the BBSA, which is on the user's mobile device z. B. Smartphone is installed.

The BBSA manages and protects the keys, calls the GSM KeySystem module and logs the actions. The use of the software is password protected. After successful login, the properties, the BBSA password and a four-digit PIN can be stored. So that no random call is initiated, a PIN request should be set up before the call is triggered. The data should be protected by encryption on the mobile device.

Keys and key groups can be added and removed. The keys contain the values designation, telephone number and optionally further fields for a more detailed description.

The BBSA is described below by way of example.

4.2 Administrator KeySystem Software Application (AKSA)

The KeySystem administrator manages GSM KeySystem modules using the AKSA. Features include initializing, setting up, transferring and deleting modules and authorized keys, logging operations, reading the data store, locking the module, and updating the module software. The transfers of the functions are realized by means of messages and connections.

In the following, the AKSA structure is described by way of example. Access to the application is protected by a password.
