Telecommunications system


(57) Abstract:

In the telecommunications system, such as global mobile phone communication network in which each subscriber unit contains a module with an identification code of the subscriber (SIM card), each SIM card has a cell constant memory to which data can be transmitted by radio. Some of the cells may not be overwritten with the subscriber device, but it can be accessed after entering a simple short codes, each of which is associated with one of the cells. For more permanent memory cell can be read on the radio only when a caller can enter individual numbers. Files lock control is used to control access to read/write to the cells, respectively. 2 and 10 C.p. f-crystals, 5 Il.

This invention relates to telecommunication systems. In particular, but not exclusively, it relates to a mobile communication system, such as system cellular mobile radio or telephone communication.

One of the latest achievements in these systems was the introduction of modules with the identification code of the subscriber (SIM card). These cards are cards with built-in integral is the capacity code of the subscriber, i.e. his phone number. Such well-known SIM cards also contain a buffer memory drum type, which can store a certain number of alphanumeric characters. This buffer memory for easy service in the mode of short messages (SMS) through which the message for a subscriber or group of subscribers can be transmitted over the air in the enhanced mode system personal search call. Messages can be received by the mobile phone, even if it is idle or in standby mode. However, if one accepts the message, which can overflow the buffer, data loss occurs when implementing a data transmission mode in the order received.

In U.S. patent 5127040 described a method and apparatus for remote loading frequently used phone numbers in your mobile device. These rooms can be re-invoked and used by the subscriber subsequently.

In the European patent EP-0459344 describes how to download and implement the software in the remote terminal device (terminal) communication systems.

In document WO A-91/12698 described mobile phone containing a SIM card programmed only in the, is not remotely.

The objective of the invention is the creation of more effective and remotely reconfigurable SIM card.

According to one aspect of the invention, it is proposed telecommunications system containing at least one master station and multiple subscriber devices, with each main or main station transmits the message to at least one subscriber device and each subscriber unit has many permanent memory cells and means, responsive to detection of such a message, save the message in the selected cell constant memory that cannot be overwritten with this subscriber devices, which can optionally be accessed from the subscriber device, wherein each subscriber unit includes means, responsive to the command transmitted from the main or each of the main stations, the selective enabling or blocking of cell constant memory for recording or reading, initiated by the main or each main station, or subscriber device.

For the purposes of the present description and attached claims terminator store type or circular buffer memory. In certain cells in the permanent memory may be overwriting all of the data in contrast to the loss of information when using the method of storing data in FIFO type (FIFO) in today's buffer storage devices SMS.

Thus, for example, the number of telephone numbers, each of which has an identification alphanumeric label can be transferred to the SIM card, providing users with easy access to public services, such as reservations in hotels, rent a car or reserve tickets. This property is known as a directory service with additional services.

The ability to search messages by the subscriber by either typing a simple short codes in the subscriber unit, and each memory cell corresponds to a specific code. The message may include the phone number and after his memory may be overwritten on the radio. Preferably, each main or main station to send a request for information stored in the subscriber device. This information may be included in the message and it can also include data that is dentification number (PIN). This information may include information about the state of the credit of the subscriber, such as credit card number, the status of the loan, which greatly facilitates the transaction by credit card, produced by phone. When using this feature of the invention the holder of the credit account does not need to dictate the details of your account, and you only need to enter the required personal identification number.

The main station can transmit commands to lock and/or release the memory in the subscriber device. It can transmit commands to run programs stored in the memory cells in the subscriber device. The main station can transmit to the subscriber's device files containing functional data and/or files containing non-functional data.

Messages, requests for information and commands can be transmitted in a special format that the subscriber device can be distinguished from other formats. This special format can be protected from interception.

In a preferred embodiment, subscriber unit comprises a mobile phone and a card with an embedded integrated circuit, kotori memory cells and means for distinguishing a special format other formats. This map may contain a means of distinguishing messages, requests for information and commands. The map can also be provided with means for storing messages and a means of responding to queries and commands.

According to another aspect of the invention, a module for controlling a subscriber device in a telecommunication system, removable connected to the transceiver of the subscriber device and containing a number of cells constant memory and means responsive to the detection message, remotely transmitted to him, save this message in the selected cell constant memory, characterized in that it contains means, responsive to commands sent to it remotely, open or lock any or all of the cells in the permanent memory for recording or reading their subscriber device or the main station.

This module can have a directory structure, which can store files. The present invention may find particular application in the global telecommunications systems, in which cellular cell phones of different countries or regions of the interconnect using a common standard. At the time in Europe. However, this invention is not limited to global systems and can be applied in a single national system of cellular communication or even in a stationary network with cable connection.

Next will be described an example of a variant of the invention with reference to the accompanying drawings, which represent the following:

Fig. 1 is an illustration of the transmission to the subscriber device in the system corresponding to the invention;

Fig. 2 - the process of transferring the subscriber device, the message and the requested information;

Fig. 3 is a block diagram illustrating the elements of the module depicted in Fig. 1 and 2;

Fig. 4 is a detailed image of one of the blocks shown in Fig. 3;

Fig. 5 - sequence of operations of the module depicted in Fig. 1-4

In Fig. 1 shows the route SMS distribution according to this invention. Traditionally, short messages are usually directed to one specific subscriber or group of subscribers, such as the sales team.

However, the GSM standard also supports a property known as broadcast messages throughout the cell (service area), in which messages can be transmitted to all subscribers in a specific area. In the present embodiment, isidentifier this siren.

The operator enters a message in the terminal 1. Then the message is encoded in a protected format, known as the integrated command stream (ECS), and is transmitted through the modem 2 and the stationary line 3 local switch 4 GSM. In accordance with the delivery address, the message is sent to any or all other switches in the network, or even between networks.

The switch 4, which in this example is located in the geographical area in which it should be sent the message, sends this message to multiple mobile stations 5. Mobile station 5 are base transceiver station of the GSM network.

Each mobile station 5 then transmits a message to a group of transceivers or mobile phones, hereinafter referred to as "mobile devices". When broadcast a General message this group includes all mobile devices in a given geographical area at the time of broadcast.

The selected mobile device 6 receiving the message, transmits an acknowledgement on his mobile station 5. From this moment until you update the system no longer will again come into contact with this mobile device 6.

The mobile device 6 recognizes the message as hydrated in the slot in the mobile device 6. Card SIM 7, in turn, recognizes the built-in thread (ECS) using special hardware and software tools, and stores the message in memory so that it cannot be overwritten by the subscriber. Known card SlM contain a large number of cells constant memory, in which the subscriber can store frequently dialed number and the corresponding alphanumeric labels. Card SIM 7 according to the invention stores the message in one of these cells, and then performs the operation of write protection. Cells intended to store a write-protected messages can be marked with code numbers relating to specific categories of siren. So, for example, phone numbers companies car rental can be stored in the cell 01, reservations in hotels in the cell 02, etc.

In Fig. 2 depicts the process of placing a call in which the subscriber enters into communication with the siren. The subscriber, remembering that the room rental companies hire is located in the cell 01, as shown by the position 8, enters from the keyboard short code corresponding to the given memory cell, for example 01#. Then the mobile device 6 transmits a request to the SIM 7 to read the phone number from Dunn is rmatio for display to the subscriber. The user confirms that he wishes to proceed by pressing SEND (send).

The mobile device then receives the channel tone frequency on which the call arrives at the dialed number. The GSM system automatically handles inter-network and inter-network transitions from this point, the user can carry on a conversation with the company.

If the company has established the proper equipment immediately after answering the call information with the identification code of the subscriber, read from the SIM card 7, immediately provide the company with detailed information for billing the user, such as his name and address.

Card SIM 7 also contains information that reflects the state of the credit of the subscriber. This information is in a separate protected memory cell, which can be accessed only when the user enters the required personal identification number PIN known only to him, thus confirming that the mobile device has been stolen or lost. After confirmation by the subscriber of your order on the rental car he enters the PIN number in the mobile device 6, requesting information on the loan from the SIM card 7. Card SIM 7 gives this info the formation of the company in the format tamper detection. Deal confirmed by the company or its hardware and the call ends.

In this example, it is also possible to obtain the telephone number or Fax number in the help system directory maintained by the operator, without the need of a caller can enter manually the desired rooms in the terminal communication systems.

To use this option, the caller calls the information service network and reports the name of the person, company name, or service, the room in which he wants to receive, as well as any additional information that may prompt the operator answers the call. The operator then finds the room, confirms it and asked how to transfer this number: orally, via SMS to a specific memory location on the map SIM subscriber, or both.

If the subscriber decides to update the SIM, the conversation stops and the operator initializes the SMS process by entering a certain sequence in the computer or start the special keys. Then this phone number is encoded in the message ECS in the control centre and is sent by the network to the subscriber terminal, which transmits a confirmation of dispatch service. So the>User terminal recognizes the message as SMS data passes it on SIM card and, if applicable, displays the text "received message". Card SIM, in turn, recognizes the ECS using special hardware and software and decodes it. Number and any associated alphanumeric character, which usually consists of a person's surname or the business name, restored together with the memory cell in which you plan to save them. The number and the nominal characteristic then written into the cell and is protected from recording, if so desired pass, and overwrite protection is encoded in a message to its source.

Then the subscriber attempts to place a call to this number in the known memory cell, typing with the keyboard the number of the memory cell. The SIM sends the telephone number or Fax number to the subscriber terminal upon request and after receiving confirmation from the subscriber terminal communicates on call with the given ID.

In Fig. 3 shows the electronic structure of the SIM card. The card communicates with the mobile device to which it is connected, via the control unit input / output (1/0) 15, preferably using the Protocol ISO 7816 T=0. The filter 16 expected ECS is passed directly to the extended erasable ROM (E2ROM) 17, which is preferably a ROM with a flash erase. Data can also be displayed from the extended erasable ROM directly to the control unit 1/0 15. The remaining blocks shown in Fig. 3, are standard components of the SIM card.

In Fig. 4 shows how advanced erasable ROM. The root directory contains 18 administrator ID and SIM 19, catalogue GSM and data network 20, and telecommunications directory 21.

Telecommunications directory in turn contains the following memories: "abbreviated dial" 22, "configuration features" 23, "short messages" 24, "fixed dial" 25 and "boot counter 26. Each block represents the set of memory cells. Often the dialed number and the corresponding alphanumeric characters stored in cells 22.

Cell 22 with reduced numbers set" and cells with 24 "short messages" are all associated files lock control 27, 28 respectively. The file control block and serve as a means to protect against read/write and unprotect from reading records with their associated memory cells. The file control block 27, 28 in a typical case, the CTE, for example in the admin directory.

In Fig. 5 shows the sequence of operation of the SIM card 7, which uses special hardware and software tools described above to implement the operations shown. In block 9 messages, queries, and commands with ECS, are distinguished from those messages, queries, and commands that do not have it. Each of these types of ECS consists of a stream of data, identified by a team of one of the at least four types: a write command message, the command read requests for information, attribute commands for the commands of the lock or unlock command and run for teams on the implementation of the program run.

The types of commands and data are decoded in block 10 and processed by one of four routes 11-14.

Route 11 are processed by the write command, stores the message, starting with the cell specified in them. Route 12 is processed commands read; and in this case, the request information includes the selected cell, the access to which should be first. Read sequential cells, and data is stored in the buffer memory until, until you read the and, using SMS, caller.

On route 13 attribute commands are used to lock or unlock the specified memory cells, to open or close them to access the callers or the user. Route 14 teams run called run of a program stored in the SIM.

The main ECS can be expanded to 255 internal shell commands, four examples of which include write, read, lock/unlock and run the program. A special Protocol used to transmit information, is not fixed and may be ISO 7816 T=0, or any other suitable Protocol.

Internal shell commands are in addition to the system's ability to create an external file objects in a SIM card 7. The object files can be of two types: program files, application data (ADFP), containing functional data that can be executed by the processor of the SIM card and offline can be modified if necessary, and the application data files (ADF), containing non-functional data that does not have these features. Available ADF can be modified by radio, providing advanced capabilities such is the established levels of directory, similar directory disk drives of computers, and new ADF(P) can be loaded into any directory on the radio. Also on the radio, you can create, destroy and modify the directory, you can perform different operations with the tree and remove the ADF(P) that are no longer needed. The amount of data ADF(P) that can be downloaded is limited only by the size of the extended erasable ROM card.

The proposed invention significantly extends the use of SIM cards. For example, using the directory service with additional services, subscribers can quickly and easily book hotels and tickets for flights through their mobile devices.

An additional advantage of this characteristic of the invention lies in the fact that facilitated the geographical distribution of the messages on the cards in a specific area, for example in the South of France. Therefore, advertisers can directly send your own messages to all subscribers of mobile devices in a particular zone. This is especially useful when callers "travel" from one zone to another and do not have information about local services.

Download directory requests you can send your contact phone numbers or Fax on the target connected with ustroistvoto, often dangerous, especially if the caller is behind the wheel.

The ability of the system to load the ADF(P) means that additional services may be provided by the SIM card on the radio, while retaining the General compatibility with existing cellular systems. Therefore, the SIM card can be purchased options credit cards, passports, driver's license, pass, Parking, membership and so on, becoming a multi-function card. In addition, can be added dynamically updated services that require different processes at each access to any service.

If the map provide additional services, it can be used outside the environment of the mobile phone as a standalone item. It can be read or it may be account specific hardware tool, such as a cash register terminal. Optionally, you can exclude new services, however, the map will not lose your SIM for your mobile phone. In addition, if the card provides additional services, they will continue to operate even when the subscriber is disconnected from the mobile telephone network, if not expressed in the SIM card can be programmed to only receive messages about services of interest to the recipient.
