Description

The present invention relates to the field of information and telecommunications, namely the provision of information services in terms of user mobility.

When traveling (indoors, outdoors, in transport, etc.), objects that we would like to have and store certain information in our memory often fall into our field of vision. For example, having noticed a beautiful building, we would like to know and remember its exact name, the name of the architect, etc .; Having noticed the sign “Train schedule”, we would like to look at the schedule itself and save it documented; having noticed an advertising poster of any company, we would like to receive a detailed description of a particular advertised product, etc.

Traditionally, information on objects falling into the field of vision in most cases can be requested and obtained only by referring to the “initial data” of the object, such as, for example, its exact name, name of the manufacturer and its phone number, address of the corresponding Internet page and etc., for which it is necessary to find and remember (record, save) this information, enter it into the device of the information system (telephone, PC, PDA, etc.), and to send a request you must have access to the communication system - telephone network, Internet, elek ronnoy mail or other resources. All these actions require certain efforts, time and the availability of appropriate equipment, and are often simply impossible if the user does not have access to communication networks or is experiencing physical inconvenience while in cramped circumstances.

The practical use of mobile Internet technology based on 3rd generation mobile communication standards (“3G”) UMTS, CDMA2000, WCDMA, WLAN, Wi-Fi, etc., significantly expands the capabilities of mobile information support. (see, for example, Daniel Collins, Clint Smith. 3G Wireless Networks. McGraw-Hill Telecom Professional. 18 Sept., 2001; Vl. Kirillov. Third Generation in Russia. "Mobile Systems", No. 9, 2000; www. .3gnewsroom.com), providing a wide subscriber coverage area, high speed wireless data transfer and, accordingly, the ability to quickly search and download network information resources to the recipient's receiver - a mobile terminal of a 3G network subscriber. However, the construction of such networks requires enormous financial costs, the availability of appropriate terminals for subscribers and does not completely solve the problem, while retaining the need for the user to search and manually enter object data and the presence of radio coverage of the mobile communication system. And even in conditions of wide availability of the mobile Internet, the necessary information is far from always available on the Web.

For subscribers of cellular networks, additional information services related to their location are provided using positioning methods and techniques (see, for example, Igor Skolotnev. Positioning of mobile phones. North-West Telecom (St. Petersburg), No. 3 (11 ), 2000; Mobile Communications International / RE, 7-2000; AC No. 2199821, WO-2003009610 A1, WO-2003005747 A1). A subscriber of a cellular network is offered the so-called. positioning services (LBS - Location Based Services), upon subscription to which the network operator monitors the position of the mobile terminal and, together with the service provider, organizes the sending of notifications or links to the subscriber about objects located near him and during his movement, usually objects of wide demand (restaurants, cinemas, museums, shops, etc.). The disadvantage of this solution is the limited choice of the recipient of information, i.e. limited number and range of objects, the presence of which the subscriber receives signaling information. In addition, to obtain such information, good radio coverage and the presence of a special terminal for the subscriber are also required, and for the exact determination of the coordinates, a GPS positioning device is required. Moreover, the accuracy of determining the location is low and is more than 30-50 m.

In order to expand the selection, facilitate the search for information and simplify access to information resources using a mobile phone with an Internet browser or PDA, methods and devices for providing information by sending it to the recipient via an email server are proposed (patents WO-200291235, US-2002165916). When sending an electronic message to the server, the latter recognizes and fixes the email address of the sender. In order to provide the recipient with access to certain types of information and automatically send information to the recipient, he is invited to enter the codes corresponding to the requested information into the sent request. At the same time, a certain coding scheme is proposed that facilitates the selection of the required information and simplifies sending a request from a mobile phone. The disadvantages of this method are as follows:

- approval of the proposed code system by a large number of users is necessary (standardization);

- one way or another, manual entry of data of the information object of interest is required;

- sending a request for information is possible only if you have Internet access and radio coverage;

- the search for the object of interest and entering its data is not facilitated when the recipient is near the request object or the identifier of the requested information.

With regard to the elimination of the first and last of the listed drawbacks, there are interesting known methods and devices for providing information on objects falling into the field of view or photographed objects (US-2002165801; JP-2003018638), in which the name and location data of the object are transmitted via a mobile phone to a server producing selection of relevant information from its database and ensuring the sending of this information to the recipient’s mobile terminal. However, these decisions also have such disadvantages as the need for some form of manual data entry of the object of interest, Internet access and radio coverage.

A method and device for providing information through objects that identify information (information identifiers) that may be encountered by a potential recipient of this information during its movement (walking along the street, in transport, etc.) without the laborious manual input of “source data” into the terminal (ID) of the requested information and when the recipient is located next to the identifier, proposed in patent US 2002/0116268 A1. On the object that identifies the information (for example, on an advertising poster for a product of a company), an “RF-ID tag” is placed, that is, the place of information contact, designated as referring to certain information, in which the emitter is installed a radio signal containing information or a network link to this information. A device that receives the signal emitted by the “RF-ID tag” and reads and stores information is embedded in the recipient’s mobile terminal. This information may contain a link to a network resource, for example, the address of the corresponding Internet page, which then accesses the network resource downloaded to the recipient’s mobile terminal.

In this case, the recipient is completely spared the need to search and manually enter the source data of the information of interest to him when the recipient is near the identifier of the information. In addition, to obtain and store information in the memory of a mobile terminal, the presence of radio coverage of a mobile communication system is generally not required.

The main disadvantage of this technical solution, which is closest to the proposed one, is that the emitted radio signal creates radio interference. Given the likely location of objects that identify information in “hot spots” (in crowded places and a large number of mobile radio devices), the negative effect can be all the more significant. To reduce the level of radio noise, the power of the emitted radio signal should be minimal, and this requirement leads to a significant reduction in the distance of reception of the information signal by the reading device of the receiver. In addition, the use of radio-emitting devices does not allow them to be placed close to each other due to interference (interference of radio signals). In addition, devices emitting a radio signal are complex, expensive and have limited reliability, which is essential when creating a capacious information network with a large number of information identifiers.

In addition to the main additional disadvantages of the known technical solutions are the following:

1. The information message of the emitted radio signal is limited in volume and usually represents only a link to a network resource and (or) contact data for further contact for more detailed information.

2. The content of the information provided to the recipient does not take into account the fact and parameters of the request for information (for example, time, place, user data, preferences, etc.), which limits the possibility of providing information services.

3. Changes and additions to the information signal must be made for each device emitting an information signal, which is very laborious when using a large number of information identifiers.

4. The need to install a special reader in the user terminal.

The objective of the present invention is to get rid of radio interference, as well as address these disadvantages.

The proposed method is as follows:

A photodetector is installed at the object that identifies the information, to which a modulated optical signal is sent containing the address of the recipient, the signal from the photodetector is transmitted to a server informationally connected with the requested information, and from the server, the requested information is transmitted to the receiver of the recipient.

The set of features set forth in claim 2 of the formula characterizes a method of obtaining information in which laser radiation is used as an optical signal carrier. It is proposed to use optical radiation both in the visible range of the spectrum and in a wider range, for example, infrared (IR) radiation.

The set of features set forth in paragraph 3 of the formula characterizes a method of obtaining information in which a mobile terminal (telephone, pager, laptop, PDA, etc.) is used as the receiver of the recipient.

The set of features set forth in paragraph 4 of the formula characterizes a method of obtaining information in which the recipient’s computer uses an email server (email WEB server, LAN proxy server, home or office PC, etc.).

A fixed terminal (fixed telephone, ISDN telephone, PC, laptop, PDA, etc.) can also be used as the receiver of the receiver.

A server informationally related to the requested information is understood to mean a network node or a series of interconnected network nodes containing (x) a database with information corresponding to information identifiers, and hardware and software that provide:

- recognition and recording of the optical signal to the photodetector,

- identification of the photodetector to which the optical signal is sent,

- appeal to relevant information resources / databases,

- the formation of the contents of the message sent to the recipient,

- transfer of information to the recipient by sending it electronically to terminals or electronic mailboxes in accordance with the requests and data of the recipients.

The functions performed by the server may additionally include, in whole or in part:

- identification of the user of the device or the recipient of information,

- authorization of the possibility of providing him with services,

- accumulation of incoming requests and fixing their parameters,

- formation of offers of additional services,

- circulation and transmission of information to servers or nodes of communication networks, such as servers for services of paging or cellular communication operators (servers for sending SMS messages and access to mobile operators' WAP or Internet, servers for email services, etc.).

The optical signal sent to the photodetector, in addition to the address of the recipient (his email address, mobile or fixed phone number, client data of the proxy server of his home or office computer, home address, etc.) may additionally contain, in whole or in part, such data, as:

- emitter device code,

- recipient authentication code,

- specification of the request object, type, quality, format size or other parameters of the information provided,

- additional request parameters or message.

There is a device for receiving information that implements the proposed method of obtaining information containing the identifier of the information, the receiver of the receiver, a server with software for processing requests for information and sending it to the receiver of the receiver, characterized in that it further comprises a modulated optical radiation source and a photodetector on the information identifier and connected to the server.

The combination of features set forth in paragraph 6 of the formula characterizes a device in which a laser is the source of modulated optical radiation transmitting the request signal.

The set of features set forth in paragraph 7 of the formula characterizes a device in which the radiation source contains a block of hardware and software for inputting data of the sent signal.

The set of features set forth in paragraph 8 of the formula characterizes the device in which the radiation source is combined with the recipient's mobile terminal.

The set of features set forth in paragraph 9 of the formula characterizes a device in which the hardware and software for inputting data from the sent optical signal are combined with the hardware and software of the user's mobile terminal.

The set of features set forth in paragraph 10 of the formula characterizes a device in which identifiers of information have indicators of difference depending on the parameters of the information received.

The set of features set forth in paragraph 11 of the formula characterizes a device in which the identifiers of information contain indicators of the operational status and readiness of the photodetector and (or) server to process requests.

Thus, in contrast to the known technical solution, instead of the mobile device reading out the radio signal information emitted by the identifier from the information of interest to the recipient, the recipient data is sent to the photodetector installed on the information identifier using modulated optical radiation, and the information contained in the identifier is contained in database, based on the address of the receiver and identification of the photodetector is sent to the receiver of the receiver through the server. Accordingly, instead of a device that reads the emitted radio signal, the user is equipped with a device that emits an optical signal, and instead of placing an active device emitting a radio signal on the information identifier, it is proposed to place a passive device on the information identifier that receives the transmitted optical signal and converts it into an electric one (photodetector) and connected to the server.

The absence of the use of radio emission in information exchange through an information identifier provides a solution to the problem of eliminating radio interference. Due to this, the following advantages are achieved:

1. The ability to place many information identifiers in close proximity to each other, since photodetectors, unlike radiators of a radio signal, do not create interference of information signals. In particular, when using a laser beam as an optical signal carrier, the diameter of which for this application does not exceed 1-2 cm, the photodetectors can be located at a distance of several centimeters from each other.

2. Significantly increases the range of information contact with the information identifier. The propagation distance of the visible spectrum of a low-power laser without a significant loss in radiation intensity reaches several hundred meters.

3. Photodetectors are simpler, more reliable and less expensive than devices that emit a radio signal. This is especially important when creating an extended information network with a large number of information identifiers.

In addition, the proposed technical solution has several additional advantages and features:

- A significant increase in the volume and variety of formats of information received due to the possibility of sending it to the recipient's email inbox.

- Ability to send a request and message and receive information without the presence of radio coverage of a mobile operator. To send a request or message to the server, the user only needs to have a radiator (optical or IR communicator) and be at a distance from the photodetector sufficient to perceive the sent signal. This makes it possible, moving in the reach of photodetectors, to realize mobile two-way communication without a mobile phone, having only an optical or IR communicator in hand and having a one-way channel for receiving information - for example, paging communication.

- Greater flexibility compared to the well-known technical solution: it is possible to make changes and additions to the information provided to the recipient at the server database level, regardless of the objects that identify the information and photodetectors, which is especially effective when using a large number of information identifiers.

- Expanding the capabilities of information services due to the fact that registration of user data, the place and time of his request for information is provided. The information provided can be clarified depending on the place and time of sending the signal to the photodetector of the information identifier, as well as on the basis of the recipient's data and expressed preferences in the content of the signal sent to the photodetector. In addition to the basic information corresponding to a specific identifier, the content of the response message sent to the recipient may include, for example, an offer of additional services related to this request, advertising or other additional information.

In particular, the application of the proposed method will complement those services that are provided by communication network operators to their subscribers. So, for example, LBS positioning services for subscribers of cellular networks can be implemented without the use of special means of determining the location of a mobile terminal: when an optical signal is received, the subscriber’s location is precisely determined by determining the identifier of the information to the photodetector of which the optical signal was sent.

On the other hand, this technical solution allows you to create independent networks of information support, independent of the operators of mobile or fixed communication networks.

- It is possible to send information to any and more than one address specified in the sent optical signal.

- Simultaneously with sending the requested information, it is possible to organize the sending of a notification of sending information to the alternative address of the recipient or other addressee.

- The information provided does not have to be posted on an open Internet site, but can be sent from a private, closed database, accessible only to users of this technical solution.

- Ease of use of the laser beam as a pointer / cursor when selecting the desired information identifier.

The emitter of the optical signal (optical communicator) can be used independently, without being combined with the mobile terminal of the recipient. The emitted signal can either be “wired” (programmed without the possibility of change) to the emitter, or be programmable. This is important if you need to make changes to the content of the optical signal, set preferences or send additional information or messages to the server. In this case, the emitter may be additionally equipped with hardware and software for inputting data of the sent signal, such as, for example, a signal programming unit with a data input interface (for example, a keyboard) and a storage device.

On the other hand, when using a mobile terminal as the receiver of a receiver, it may be appropriate to combine an optical communicator with a mobile terminal for ease of use. When using a mobile phone, it is advisable to combine hardware and software for inputting the emitter data with those of the mobile phone (for example, with the telephone keypad).

Below the invention is explained in more detail on the example of three options for its implementation, not exhaustive of all possible options, with reference to the accompanying drawings, which show:

Figure 1 - diagram of the implementation of the proposed method and device using an IR communicator and email.

Figure 2 - diagram of the implementation of the proposed method and device using a laser communicator and pagination communication.

Figure 3 is a diagram of the implementation of the proposed method and device using a laser communicator, combined with a mobile phone.

The recipient found the information identifying object 1 (Fig. 1), which in this case is a company poster N hanging on the metro station's wall, representing the product P. of interest to the recipient. A photodetector 2 is installed on the poster. In order to receive and document a more detailed description of the product P, the recipient turned on his wrist infrared communicator (ICC) 3, which is the source of the modulated infrared optical signal containing the recipient address, directed the infrared radiation stream 4 in the direction of identi information indicator 1, having hit radiation on photodetector 2 and, in a hurry, entered the car of a train that approached. The modulated optical signal 4, converted into an electrical signal by the photodetector 2, containing the autodetection code k of the IR communicator 3 and the recipient’s email address mmm@nnn.ru, was transmitted to the optical communication service server 5 (COC Server) of N. Server 5 performed the authentication The IR communicator 3, determined that the signal came from the photodetector 2 and, therefore, it was the description of the product P that was requested, and sent an electronic message to the receiver of the receiver 7, which in this case is an electronic server of mail (PP-SEP), to the address mmm@nnn.ru, with the attached product description file R. After leaving the metro and reaching his office, the recipient turned on his personal computer, went to the Internet page www.nnn.ru, entered login mmm, password and found a message sent to him with the attached file for a detailed description of the product R.

The next embodiment of the proposed technical solution is one in which laser radiation is used as the carrier of the optical signal, and a pager is used as the receiver of the receiver (Figure 2):

The group of information identifiers (1-6): “Weather”, “Schedule”, “News”, “Program guide”, “Photo”, “Mail” is located on the city square. These identifiers contain the photodetectors installed on them (7-12), connected to the server 13 of the laser communication service of the paging operator (Server SLS). To use the services of the laser communication information service, the recipient sends requests to provide him with relevant information using a laser communicator (PC) 14, sending a modulated laser beam 15 containing information from the information recipient (identification code k of laser communicator 2 and pager number ggg-gg-gg) , in the direction of the corresponding identifiers of information and getting a beam on the corresponding photodetectors. For example, wanting to receive and store in memory of its receiver 16, which uses a pager (PP-P), the schedule of local trains, the receiver directed the laser beam towards identifier 2 “Schedule” and illuminated the photodetector 8. The signal received by the photodetector 8 and converted to electric, it was transmitted to the server 13, which made the laser communicator 14 self-identifying, determined that the signal came from the photodetector 8 and, therefore, it was the schedule of local trains that requested I encoded the pager number ggg-gg-gg and gave the command to send a message with information about the train schedule available in the CCLS database to ggg-gg-gg.

Similarly, the recipient receives information on his pager with weather forecasts, local news, a program of local television and radio broadcasts, text sent to his e-mail inbox, etc.

An alternative implementation of this option (Figure 2) can be the use of an electronic mail box as the receiver of the receiver, as well as allowing the user to send an electronic message to any address:

Having placed with his friends in front of a digital camera lens, installed near the information identifier 5 “Photo” opposite the local attraction and connected to the server 13, the recipient directed the beam of his laser communicator 14 towards the identifier 5 and illuminated the photodetector 11. The signal containing the data of the information recipient ( the identification code k of the laser communicator 2 and the address of the recipient's electronic mailbox ppp@mail.ru) received by the photodetector 11 was transmitted to the server 13, which performed a identification of the laser communicator, determined that the signal came from photodetector 11 and, therefore, it was necessary to take a photo, recorded the e-mail address ppp@mail.ru transmitted to it and gave the command to the camera to take a photo. The file with the captured image was transferred to the server 13, which sent an electronic message to ppp@mail.ru with the application containing the photo file.

Wanting to send a letter to his friend, the user typed the text of the letter on the keyboard of his laser communicator 14 with the email address of his friend ddd@mail.ru, entered this information into the content of the optical signal of the laser communicator and, directing the beam towards the identifier 6 “Mail”, illuminated the photodetector 12. The signal received by the photodetector was transmitted to the server 13, which determined that the signal came from the photodetector 12 and, therefore, it is necessary to forward the electronic message, recorded the transmitted his e-mail address and ddd@mail.ru text of the letter and made the e-mail sending with the text of the letter addressed to ddd@mail.ru.

Another implementation option of the proposed technical solution is one in which laser radiation is used as an optical signal carrier, and a mobile phone combined with a laser communicator is used as a receiver of the receiver (Figure 3):

While in the train car approaching the city of M, the recipient noticed an identifier of the information he was interested in - signboard 1 placed above building 6 with the name of the institution - branch P of corporation N. Signboard 1 contained a photodetector 2 installed on it and connected to the server 3 of the laser communication service (Server SLS) of the mobile network operator (OMS), of which the recipient is a subscriber. Orienting the emitter of the laser communicator 5 built into his mobile phone 4 towards the signboard 1, the receiver directed the laser beam 7 through the glass of the car window and illuminated the photodetector 2. After a split second, building 6 was hidden from view.

The optical signal sent using the laser communicator 5 and received by the photodetector 2, containing the authenticator code k of the communicator 5 and the recipient’s mobile phone number xxx-xx-xx, was transmitted to the SLS Server 3, which made the authentication of the communicator 5 using the k code, determined that the signal came from photodetector 2, and information is requested specifically about the branch P of corporation N, which occupies building 6, has developed a response i to the recipient’s request indicating the address P in the city M, the addresses of the wap-site wap.nnn.ru and the Internet page www. nnn / p / m.ru (with information on the activities, goods and services of the P branch of the corporation N in the city of M, the plan of the next events P in building 6, etc.). Based on the data of the place and time of sending signal 7, the laser communication service additionally included in the content i the offer to book the remaining last admission ticket for the event held by P in the premises of building 6 at tt: tt. The text of message i was transmitted to the server 8 of the short message service (SCS Server) of the mobile operator’s network, which sent a short SMS message containing i to the subscriber with the number xxx-xx-xx. This message was received on mobile phone 4. Having agreed to attend the event held in tt: tt by sending a reply SMS, the recipient, leaving the train, went to the address of institution R. Following the R, the recipient activated WAP- or Internet browser of his a mobile phone and broadcasting the URL code of the website wap.nnn.ru or www.nnn / p / m.ru received by it through the base station 9, the mobile switching center (CCMS) 10, WAP-service gateways (WAP-gateway) 11 and access there are 12 mobile operators on the Internet (WWW-gateway), went to the WAP- or Internet site wap.nnn.ru or www.nnn / p / m.ru and I taught the necessary information.

For the purpose of practical application of the proposed technical solution, it is advisable to give information identifiers signs of distinction depending on the user's preference regarding the type, quality, volume, format or other parameters of the parameters of the information received. It also seems appropriate to indicate the operational status and readiness of the photodetector and (or) server to receive a signal.

Such functions as recognition and recording of the optical signal to the photodetector, user identification, authorization of the possibility of providing services to him, accumulation of incoming requests and fixing of their parameters can be implemented by appropriate hardware and software located directly near the photodetectors, and not necessarily on a remote server.

The technical implementation of the above capabilities may well be implemented on the basis of modern hardware and software of network servers (see, for example, Babushkin M.O. WEB server in action. - St. Petersburg and others: Peter-press. - 1997; Dyson P. Web site based on Microsoft Internet Information Server: Complete Guide to Internet / lntranet, translated from English by V.I. Voropaev et al. - M.: Mir. - 1997; Martin M.D. Introduction to Network Technologies. A practical guide to networking: Translated from English .. - M .: LORI. - 2002).

The practical use of devices for sending a modulated light or infrared signal does not present technical and economic difficulties. IR remote controls are widely used in everyday life to control televisions, music centers and other devices. The directional transmission of information using a modulated light signal, especially when using laser radiation sources, and its conversion into an electrical signal using photodetectors is also long and efficiently used (see, for example, Thomas Petruzzellis. Optoelectronics, Fiber Optics, and Laser Cookbook. May 1997; DE-4431707; WO-200025433; WO-9952231; JP-06125310; JP-07202808). With the advent of compact and reliable portable lasers capable of delivering a visible light signal to a distance of hundreds of meters or more, this method of transmitting a signal to the desired location without interfering with it appears quite readily available and convenient, especially when traveling.

One of the directions for the further development of the proposed technical solution is the implementation of the possibility of mobile “external” network browsing (in which sending the URL to the WEB server is not tied to the user's terminal or computer, but is done through an external object — the photodetector located on the user's route), organizing the work server so that when you enter into the optical signal sent to the photodetector the URL code of the requested network resource, the content of the resource itself with hyperlinks (URL codes) is transmitted from with the help of the server at the terminal of the recipient. Thus, Internet browsing is moving from the virtual world to the real one: instead of virtual hyperlinks, real objects that identify information are used. At the same time, the visible laser beam is used simultaneously as a cursor (for “aiming” at the photodetector) and as a channel for sending URLs to the WEB server.

The widespread use of personal portable devices for sending an optical information signal and the ubiquitous location of photodetectors connected to the corresponding network server equipment can significantly expand telecommunications capabilities, providing wide access to Internet resources and the possibility of convenient mobile information exchange.
