Description

The invention relates to the operation of cellular communication networks and personal cellular communication devices. The existing level of technology

Digital cellular networks of global networks for mobile communications (POL) (O8M) are now deployed alongside wireless networks in more than 100 countries. The GSM supports the functions of the so-called Short Message Service (SCS) (8M8) in two varieties: point-to-point for sending a point-to-point message (SCS / TT) (8M8 / PP) from a network operator to a separate personal communication device, and point-to-multi points for sending a cellular broadcasting message (SCS / CB) (8M8 / CB) from a network operator to a set of personal cellular COMMUNICATION Devices located in one or more cells. For more details on the different classes of messages for SCS, refer to document “8” T.8 100 900 version 7.2 (O8M 03.38 version 7.2), the content of which is included as a reference.

The application \ ¥ O 98/10604, entitled "Interactive Cellular Broadcasting Service", illustrates and describes a method and a device for transmitting SKS / SV mapping messages for subscribers who are prompted to respond by pressing a button to immediately generate either a phone call or SKS / TT for the embedded number of the response message. One particular application of the online cellular broadcasting service is to request a service, which can then be provided via so-called over-the-air programming. Each SCS / SV message is displayed on a full display screen either immediately upon receipt, or when requested by the user. Both approaches strictly limit the interactive cellular broadcasting service with respect to the speed at which SCS / CB messages can be transmitted, as follows. First of all, the immediately displayed SKS / SV messages on the display screen interrupted the operation of the device from the point of view of the subscriber who was inclined to block this service.

Further, the storage of the SCS / CB messages requires considerable memory resources, and the requirement from the user to extract each SCS / CB message separately (then delete them separately) takes a certain time and discharges the battery.

Summary of Invention

The present invention is directed to forming a stream of various contents of some interactive display messages on personal cellular communication devices to the convenience of subscribers, so that they only briefly turn to the display screen of personal cellular communication devices, which they do to check the time. The present invention can display both point-to-point (TT) display messages and point-to-multipoint (TMT) display messages, but in the case that the TT display messages and the TMT display messages are transmitted simultaneously via their respective over-the-air interface channel, the preceding display messages usually have a display priority, so they are displayed first.

Display messages are mostly different content, including, in particular, news reports, financial information, promotional offers and the like, in the form of alphanumeric messages, picture messages, video clips and the like. Although some display messages will by nature be repeated on a regular basis, for example, display messages advertising soft drinks, the expression “mostly different” means that the same display messages are not displayed for successive time intervals, for example, between 1 and 5 min. At least some of the display messages are for dialogue in the sense that the subscriber can automatically activate the point-to-point transfer response mechanism from the designated response tool, which is fully provided for in the display message. The presence of a dedicated response tool is not necessarily displayed on the display message for the subscriber, but can be understood by him as an accessible tool. The response mechanism can be activated with a button, voice or touch key. In this case, the button activates the response tool, each response tool can be specifically assigned by the “More information” key or a key selectively assigned to the response tool, and in other cases it is a normal key, for example, the “*” key when it can appear in the display message, for example, "Click * for more information." The display message is preferably transmitted at the maximum speed of the new display message, approximately every 5 seconds on the so-called 24/7 basis, i.e. all day every day, by means of this, on the one hand, visualizing the eye-attracting service of interest in the flow of display messages, but, on the other hand, still providing the subscriber with sufficient response time to activate the response mechanism. Of course, display messages can be transmitted at slower speeds, say up to one display message about every two minutes or even slower, say one display message about every 5 minutes, and for shorter periods, for example, 10 minutes of display messages per hour only during peak hours of broadcast.

Display messages can occupy different areas of the display screen as follows. First, they can replace the so-called idle screen, which usually takes up all the space

-1006901 screen display for displaying, in particular, network-related information, such as the operator’s name, time, signal strength, battery charge, one or more voice messages and / or SCS messages stored in the permanent storage buffer before erasing them, etc. And, secondly, they can occupy a part of a split screen, for example, a horizontally positioned part for banners, which also usually has a main part for displaying a blank screen. In the latter case, the banner part can be a constant sign of the display screen or it can be replaced along with the first part in a manner similar to the first case when a non-blank screen with a specific action is called that has at least some indication of the current activity, including, in particular, the entire process from establishing a voice call to disruption, regardless of whether the subscriber is the calling party or the receiving party, or any other activity initiated by the subscriber, for example, retrieving not an object stored in memory, playing a game, writing a note, and the like. An exemplary “idle screen” in the spirit of the present invention is displayed in the so-called accessible event of a user idle screen (see 3CPP T8 3 1.1 11 V4.0.0 3111 SepegaDop Raypegkr Rgo) e1; Tesysha1 8resShsa! Jupe Shoir Tegshtak; I81M ArrPsaPop Too1ky (I8AT) (Issue 4)).

The provided flow of display messages provides the most convenient platform for m-commerce applications (mobile commerce, commerce using a cell phone), and, in particular, interactive m-commerce applications serving a wide range of ages, life styles, and the like. It is believed that its impact on a wide range of people will be much greater than from conventional radio, television and cable broadcasting services, taking into account the mobility of personal cellular devices, the fact that most subscribers now take their personal cellular devices wherever they are. walking, and the fact that they are in idle mode most of the time when they are turned on. In addition, unlike conventional broadcasting services, which are at best regional services, since each B1P1C can be addressed individually, the present invention allows much more information to be transmitted than has been achieved to date to a certain degree of structuredness of a single BTS. In this regard, additional BTSs may also be posted for the sole purpose of transmitting specific information for specific locations.

Detailed description of the drawings

FIG. 1 shows a cellular communication network I capable of transmitting a 24/7 multi-channel channel cellular broadcasting service to a set of individually addressable BTSs 2, each of which provides a bidirectional signal coverage over a predetermined geographic area having a range of so-called ordinary home pico cells covering each a few square meters, through so-called micro cells, each usually covering from a few dozen to a few hundred square meters, and up to cells covering several square kilometers.

B1II1C2 capable of transmitting point-to-multipoint messages (TMT) and point-to-point display messages (TT) to form a stream of mainly different content, mainly dialog display messages on personal cellular devices 3. TMT display messages are sent from the dispatch manager 4 display messages point-to-multipoint, and

-2006901 TT display messages are sent from the 6 point-to-point display messages manager. And display messages TMT, and display messages TT formed by the device 7 input display messages. The devices 3 include, in particular, simple portable telephones, smart cellular telephones, combined PDA (Personal Digital Secretaries) (POA) telephones, combined MP3 / MP music players and the like.

FIG. 1 also shows exemplary successively time-sensitive display messages displayed like a screen saver and replacing the usually displayed idle screen. These display messages, for example, include: “ΝΛδΝΛΟ fell by 10%. Press 8ΝΏ for details "at 9:00 and" ϋΛδϋΛΟ increased by_20% "at 9:01. The display message at 9:00 is an example of a display message that prompts the subscriber what action is required from him to receive additional information from the information provider. The display message at 9:01 is an example of a message that does not prompt the subscriber what action should be taken to obtain additional information, since he already knows that pressing the 8 button will automatically connect it to the corresponding information service.

FIG. 2 shows a display message prompting the subscriber to activate the point-to-point transmission response mechanism from a list containing: a voice call; SCS; data transfer session, for example, an Internet search session, a subscriber identity module search session (8ΙΜ), and the like; email; and facsimile transmission.

FIG. 3 shows that a cell broadcast service may include a non-terrestrial-related or nationwide program channel and one or more terrestrial-related program channels for transmitting TMT and TT display message streams from BTS logical groups, each of which includes one or more bps. Each BTS logical group either covers a wide neighboring geographical area, for example, a metropolitan area, or geographic areas that share common subjects, such as schools, along motorways, and the like. Program channels typically include time slots for the transfer of programs that are either common to a nationwide program channel and geocoded (tied to a certain area on the ground) channels, for example, news, or are intended for a specific logical group of BTS, for example : anti-drug program for transmission to the BTS of the BTS logical group that covers schools; updating the schedule for transmission to the BPS logical group BTS, which covers the main highway, and the like. In addition, a geocoded program channel can itself be segmented into two or more so-called geocoded program subchannels, each of which is to be transmitted to a subset of the BTS logical group BTS associated with a geocoded program channel, for example, a school program channel can be segmented into an initial school program. a program subchannel, a school program subchannel of a secondary school, and a college program subchannel.

It should be noted that BTSs can be assigned to one or more geocoded program channels depending on their location, for example, BTSs that cover a geographic area containing both a football stadium and a shopping mall are most likely to be assigned as for sports software. the channel as well as the program channel for purchases of the cellular broadcasting service in order to maximize its effectiveness in terms of geocoded content. In such a case, a program channel allocation scheme 8 may be provided for determining which flow of TMT or TT display messages should be displayed on each EIC. These schemes may be time dependent, for example, a sports program channel may be transmitted during a time interval beginning 2 hours before the start of a football match and ending 2 hours after the end of a football match, the program purchase channel may be transferred to other time periods available for transmissions, and the nationwide program channel can be transmitted in all other periods of time when neither the sports program channel nor the program channel purchases are available for transmission.

FIG. Figure 4 shows an exploded sequence of display messages to advertise tickets for a football show to get a seat at a stadium in gradually decreasing geographic areas and gradually decreasing prices on the day of the game, assuming that tickets not sold out are still available. Such display messages can be either TMT display messages or TT display messages transmitted to subscribers who are members of a stadium team fan club. Geographic areas are usually located around the stadium and are such that the subscriber can still get to the stadium by the beginning of the show. Such an advertising campaign can be easily applied to other objects with either a fixed sale date or limited availability, for example, to advertise the sale of consumer goods in a retail store.

FIG. 5 shows a C8M-based personal cellular device 3, including an antenna 11, a transmitter 12, a controller 13 providing a synchronization time, denoted as TSINHR, a δΙΜ-card 14 (making up an intelligent card), a subscriber interface 16, and a loudspeaker 17. Subscriber The interface 16 includes a display screen 18, a keyboard 19 and a microphone 21. The display screen 18 may be a touch-sensitive keyboard. Device 3 may also

-3006901 include voice recognition equipment 22 to support speech-activated actions, including, inter alia, dialing a phone number, calling a response mechanism, and the like. The 81M card 14 includes two fixed-size dynamic storage buffers 23 and 24 for temporarily storing TMT display messages and TT display messages, respectively, sent to it by the controller 13 before automatically dropping them in accordance with the display message reset circuit regardless of whether they are displayed or not. All control of the display message from its receipt to its automatic reset is a completely hidden process, regardless of whether the display message is displayed or not.

The operation of an application like a screen saver for each of the dynamic storage buffers 23 and 24 is as follows. The display message reset circuit automatically resets the transformed display messages from the dynamic storage buffer based on the “First entered, first exited” criterion, thereby ensuring that the dynamic storage buffer stores only the most recently received display messages and automatically resets the display messages after they are displayed. . Additionally, assuming that the display screen is available for displaying the display message, immediately before the display message is actually displayed, the following checks are performed. First, since the display messages may be incomplete due to any of several incidents, for example, interference to the air interface, transfer between cells and the like, each display message is checked for completeness, and if it is found that it is not complete, then it is automatically reset. Secondly, since at least some of the display messages are time sensitive, each display message is checked to see if it is out of date, if it satisfies the following condition: TSINCH - TPREM <TCDR, where TSINHR is the synchronization time, TPREEM is the receive time, and TEMPORTS is a predetermined time interval, for example, 3 minutes.

FIG. 7A-7E show various modes of forming a flow of display messages on a personal cellular communication device having a display split screen 26 including a main part 27 and a minor horizontal part 28 of banners. FIG. 7A shows that the main part 27 displays an idle screen, while the part 28 of the banners shows the flow of at least some interactive display messages, while FIG. 7B indicates that the display messages are only displayed on the part of the 28 banners when the idle screen is displayed on the main part 27. FIG. 7C shows that the banner portion 28 is a constant sign of the split-screen display screen 26 occupying only a portion thereof, or that it can be expanded to include the entire display screen 26 instead of the main portion 27 displaying the dummy screen (see FIG. 7E).

Although the invention has been described in relation to a limited number of embodiments, it is clear that many variations, modifications and other applications of the present invention can be made within the scope of the appended claims. For example, although the present invention is described in part with reference to its C8M embodiment, it is suitable for implementation through both existing and still developing technologies, including, in particular, PC8, CPK8, 3C, SAMA, IMT8, XU-SAMA and similar, and / or both existing and developing services, including, in particular, RTM-M, RTM-O, 1P-M, ME8, and the like.
