DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for transmitting information such as news and weather forecast to a portable terminal device in real time according to a user's request (hereinafter, referred to as "electronic newspaper communication system").

[0002]

2. Description of the Related Art Mass communication media used daily include broadcasting such as television and radio and newspapers. Broadcasting is programmatic and sequential, while newspapers are random access,
Users can freely select the reading order and field,
Also, since it is easy to repeatedly read the same information, it is more convenient for the user than broadcasting.

[0003] However, since there is a restriction that newspapers cannot be obtained unless they are delivered to each house or purchased at a predetermined sales office, information such as news and weather forecasts (hereinafter simply referred to as “newspapers”) published in newspapers An electronic newspaper communication system has been proposed in which information is transmitted to a portable terminal device possessed by an individual using wireless communication.

A conventional electronic newspaper communication system will be described below with reference to FIGS. 40 and 41. FIG. 40 is a schematic diagram showing an outline of a conventional electronic newspaper communication system, and FIG. 41 is a schematic diagram showing an example of an outline of a portable terminal device according to a conventional electronic newspaper communication system.

[0005] In FIG. 40, a server 4001 is a server for transmitting information installed in each mass communication service provider, an exchange 4002 is a relay station provided in a B-ISDN network, and a B-ISDN. They are connected by a line 4003. The base station 4004 transmits the information transmitted by wire to each user's portable terminal device 4005 through wireless communication.
Send to 4007.

In FIG. 41, portable terminal device 4101
Has a display portion 4102 and an antenna 4103. The display unit 4102 includes a title display unit 4104 indicating which mass communication provider provides the information (for example, “XX newspaper” is displayed), a menu selection unit 4105, and a menu of the currently selected menu. It has a heading section 4106 for displaying a heading, and an image display section 4107 for displaying an image relating to the currently selected menu.

FIG. 41 shows an example, and the number of menus in the menu selection section 4105 may be any number other than the nine shown in the figure. A method in which the user presses the screen with his / her finger to make a selection using a touch sensor can be used.
Also, the heading section 4106 can provide an arbitrary number of headings, can change the size of characters according to the degree of importance, and can have an arbitrary number of heading layers. Further, the area ratio occupied by the image display unit 4107 in the display unit 4102 is also arbitrary.

Menus (items) of newspaper information include, for example, “weather”, “politics”, “economy”, “sports”,
“Culture”, “game”, “fiction”, “music”, “nature”, “health”, “course”, and the like can be considered.

The operation of the conventional electronic newspaper communication system having such a configuration will be described.

A portable terminal device 4 which is a mobile station for mobile communication.
When the user having any of 005 to 4007 wants to read the newspaper information, the user turns on the power of the portable terminal device 4101 to be in the operating state. The display unit 4102 displays icons or keywords for each information field, and the user selects information to read. This demand is for antenna 4
The information is transmitted from the base station 103 to the base station 4004, passes through the B-ISDN line 4003, passes through the exchange 4002, and reaches the mass communication company providing the requested information as calling information.

[0011] The mass communication company receiving the demand from the user transmits the requested information. The transmitted information reaches the base station used by the portable terminal device of the user who issued the demand through the B-ISDN line 4003 and the exchange 4002, and issued the demand by wireless communication. Sent to the user's mobile terminal device.

The newspaper information that has arrived at the user's portable terminal device is composed of characters, voices, still images, and moving images.
002 is displayed. The user can send the next demand by looking at the display.

Although such newspaper information is expected to reach several tens of megabits, the B-ISDN network requires a communication time of about 1 second and a wireless communication section requires only a few seconds of line occupation time. Can be

As described above, according to the conventional system, newspaper information can be downloaded to the portable terminal device according to the demand of the user, so that the newspaper information can be downloaded to each house or purchased at a predetermined sales office. In addition, only necessary newspaper information can be easily obtained.

[0015]

However, in the conventional system, there is a problem that the capacity of the user is not large enough for practical use, and if traffic is concentrated, it is impossible to provide information corresponding to the demand of the user. .

Hereinafter, the user capacity in the conventional system will be described.

Since the information to be provided is newspaper information,
It can be guessed that 1) there are many business people, and 2) the time of use is concentrated during morning and evening commuting and rush home.

Here, for the purpose of peak traffic estimation, the Yamanote Line in Tokyo is assumed as a place where businessmen commuting to the company by train are most concentrated. Assume that the commuting zone is a radius of 40 km and the commuting population is 5 million. It is also assumed that 50% of all commuters have potential users of electronic newspapers who currently have a habit of reading newspapers on their way to work, or who will read electronic newspapers.

In addition, traffic is measured at 21 major stations in the Tokyo metropolitan area (Yamanote Line and surrounding areas) (Tokyo, Shimbashi, Shinagawa, Shibuya, Shinjuku, Ikebukuro, Nippori, Ueno, Akihabara, Yurakucho, Hamamatsucho, Gotanda, Meguro, Ebisu, Takada) It is assumed that 90% of them are concentrated in Baba, Sugamo, Komagome, Oji, Tabata, Hirokoji, Kanda), and that the most concentrated time period is 30 minutes from 8:00 am to 8:30 am.

Under this assumption, if the user sends a demand once a minute, that is, selects a menu and requests the next information, the system issues 3,570 demands per minute. A call will be made.
Further, assuming that information transmission (information capacity is 10 megabits) for 2 seconds from the base station is performed in response to one demand from the portable terminal device, the average transmission information amount per second is 29.
7.5 megabits.

A radio base station shall be installed at each station on the Yamanote Line, and the area of the station and the area around the station shall be 300 m × 10
Assuming that the distance is 0 meters, three wireless base stations having a service area with a radius of 50 meters are provided at each station, and if each wireless base station can transmit downlinks at a speed of about 100 Mbps, the above 297.5 megabits / Second demand.

However, each base station has 156 Mbps.
Even if it accommodates one B-ISDN line,
It is difficult to realize the above 100 Mbps / group. This is because when error correction is performed, the wireless transmission speed is about 1.5 times. Also, taking into account the period allocated to the access channel and the control channel and the period corresponding to the simultaneously generated upstream demand call, the period available for the downstream user channel is considered to be about 90%. Further, considering the loss time in the connection procedure and the loss time due to the delay in the data transfer process, the period that can be used for the downlink user channel is considered to be about 70 to 80%.
Taking these conditions into account, a substantial 100 per second
In order to realize megabit information transmission, about 21
Transmission at 5 Mbps is required.

However, the frequency bandwidth provided to the radio base station is generally not sufficient. Assuming that the frequency bandwidth per wave of wireless transmission is 20 MHz and the modulation method is 8PSK, the wireless transmission speed is 60 Mbps and the modulation method is 1
Assuming 6QAM, the wireless transmission rate is 80 Mbps. However, since transmission in 16QAM also increases the error rate, it is desirable that transmission can be performed at about 8PSK. Assuming that the modulation method is 8PSK and the wireless transmission rate is 60Mbps, 2
To accommodate 15 megabits of information, it is necessary to divide the service area into four directions using a sector antenna, and four radio equipment of 60 Mbps are required. This is a geometrical arrangement in which antennas that always face each other are always present, and this poses a serious problem in determining the arrangement for frequency repetition.

As described above, the conventional electronic newspaper communication system cannot practically meet the needs of the newspaper information providing service in Tokyo in terms of user accommodation capacity. Moreover, in order to have sufficient capability for practical use, enormous infrastructure facilities such as installing nine base stations at each station or using three frequency channels are required.

The present invention has been made in view of the above points, and has as its object to provide an electronic newspaper communication system capable of increasing the number of accommodated users without increasing the number of base station devices installed.

[0026]

SUMMARY OF THE INVENTION The gist of the present invention is that the same information to be transmitted to a plurality of portable terminal devices at the same or substantially the same time is transmitted only once, thereby improving the transmission efficiency of a wireless communication section. It is to improve.

(Embodiment 1) An electronic newspaper communication system according to Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a schematic diagram showing a schematic configuration of a radio frame in the electronic newspaper communication system according to Embodiment 1 of the present invention. FIG. 2 is a radio base station of the electronic newspaper communication system according to Embodiment 1 of the present invention. It is a principal part block diagram which shows schematic structure of a station device.

In this embodiment, time division multiplexing (Time
Division Multiple Accesses
s; hereinafter, referred to as TDMA) mobile communication, when the base station apparatus receives the same demand from a plurality of users in a short time, carries the same content from the base station apparatus in the same channel slot. Make a call to the terminal device.

That is, it is unlikely that the above 3,570 demand calls / minute are all different demands, and it is considered that the same demand always exists in them.

Here, if the time during which the user does not feel a delay in downloading information is up to 5 seconds, the demand generated in 5 seconds is about 300 demands, and 30% of the demands are duplicated. If it is a demand, the downlink transmission capacity from the base station that provides the newspaper information in response to the demand call can be reduced by 30%.

That is, by transmitting information in a multicast manner to a plurality of users who have issued the same demand, it is possible to obtain an effect of reducing the transmission capacity in accordance with the rate at which the same demand is included.

Hereinafter, a method in which the base station apparatus multicast-distributes the same information to a plurality of portable terminal apparatuses that have issued the same demand will be described with reference to FIG. FIG. 1 is a schematic diagram showing a radio frame configuration of a downlink radio channel according to Embodiment 1 of the present invention.

In the TDMA system, as shown in FIG. 1, a plurality of radio lines are formed by a chain of radio frames. The unit frame 101 is a basic unit of a radio frame.

The unit frame 101 is composed of an access channel 102 for preparing a line connection, a control channel 103 for performing line control, and a user channel 104 for data, ie, user information.

The control channel 103 is composed of a set of control channel slots 105 for one user.
The user channel 104 is composed of a set of user channel slots 106 for one user.

The next unit frame 107 follows the user channel 104. Such connection is repeated to realize a plurality of wireless communication lines.

In this embodiment, when the base station apparatus determines that the demands from k users among the users who have made demand calls are the same, the mobile terminal apparatuses of these k users Receive the same user channel slot.

That is, the downlink control channels (CCH # (l−1) to CCH #) assigned to the k users
(L + k)) accommodates a comment indicating the same user channel slot UCH # g. Thereby, in the user channel in the frame, it is possible to reduce the capacity corresponding to the information of (k-1) persons.

Further, during a period in which k users are simultaneously calling the same demand, another m users have the same demand for contents different from the demands issued by the k users. Is called, the downlink control channels (CCH # (n-1) to CCH # (n-1) to CCH # (n-1) to C
CH # (n + m)) accommodates a comment designating the same user channel slot as UCH # h. As a result, in the user channel in the frame, the capacity corresponding to the information of (m-1) persons is further reduced.

The above allocation method will be described with reference to the example shown in FIG. FIG. 1A shows the allocation at the normal time.
That is, the control channel slots A to E assigned to the portable terminal devices of the users A to E instruct to acquire the information of the user channel slots A to E, respectively.

Here, in the base station apparatus, the demands generated by the users A and B are the same, that is, the information transmitted from the base station apparatus to the users A and B is the same.
, The user channel slots A and B have only one user channel slot A ′, and both the control channel slots A and B acquire the information of the user channel slot A ′. To instruct.

Similarly, when the base station apparatus analyzes that the demands issued by user C, user D, and user E are the same, user channel slots C, D, and E are assigned to one user channel. -Only slot C ', control channel slots C, D, E all instruct to acquire information of user channel slot C'.

As described above, in the downlink radio channel, the same information is not repeatedly transmitted, and the portable terminal, which is the mobile station requesting the same information, is instructed to look at the same user channel slot. As a result, the capacity of the user channel can be used efficiently, so that the free capacity (corresponding to Δt in the figure) increases, and the number of users that can be accommodated can be increased.

Next, the configuration of the base station apparatus of the electronic newspaper communication system according to the present embodiment will be described using FIG.

The base station apparatus comprises a main body section 201 and a sector type antenna section 202. The base station apparatus is connected to the backbone network via an ATM line 203 by wire, and is wirelessly connected to the mobile terminal apparatus 204 as a mobile station via the antenna section 202.

The main unit 201 includes a network interface (hereinafter, referred to as an I / F) unit 205 for receiving an ATM line 203 from the backbone network, and a multiplexer (hereinafter, referred to as an I / F) for distributing a line to a sector antenna corresponding to a user position for each communication.
MUX) unit 206, a TDMA unit 207 for time-division multiplexing the distributed signals of each line, and a modulation / demodulation unit 208 for performing modulation processing of a transmission signal and demodulation processing of a reception signal.
And a transmission / reception unit 209 for transmitting / receiving radio signals, a control unit 210 for controlling the operation of each unit, and a line control unit 211 for managing transmission / reception of signals.

When a plurality of users issue the same demand within a short period of time, the MUX unit 206 analyzes that the issued demands are the same, and notifies the line control unit 211 to that effect. The line control unit 211 transmits a plurality of mobile terminal devices 204 that have issued the same demand on the downlink wireless line.
Are assigned to the same slot as already described with reference to FIG. Thereby, the plurality of portable terminal devices 204 that have issued the same demand can receive the same information.

[0092] The control unit 210 controls the plurality of portable terminal devices 20.
4 generates a common demand signal from the same demand transmitted from the ATM line 203 from the network I / F unit 205.
To the server of a mass communication company (not shown) that provides information. The server of the mass communication company that has received the demand transmits information corresponding to the demand.

As described above, in this embodiment, the user
Since the channels can be used efficiently, the number of users that can be accommodated can be increased.

For example, if 30% of demand calls overlap, the amount of information transmitted on the downlink can be reduced to about 70%. As described above, the actual operation requires transmission at about 2.15 times the actual transmission speed. Therefore, the information amount required to be transmitted at substantially 100 Mbps / practically 215 Mbps in the conventional method is:
In the present embodiment, substantially 70 Mbps / 150.
It can transmit at 5 Mbps.

Here, assuming that the frequency bandwidth per radio transmission wave is 20 MHz and the modulation method is 8PSK,
The wireless transmission speed is 60 Mbps. Therefore, three radio base station apparatuses are provided, and each base station divides the service area into three directions using a sector antenna, thereby providing the above-described 29 radio base station apparatuses.
7.5 megabits per second of demand, or 3,570 demand calls per minute for the entire system.

As described above, according to the present embodiment, each base station can change the service area from the conventional four directions to three directions, and the base stations are arranged in a geometrical manner in which there is no azimuthally opposed antenna. Since the arrangement is performed, the problem of the arrangement determination of the frequency repetition use is reduced. That is, since the main axes of the directivity of the opposed antennas are arranged with a shift of 30 degrees,
The number of base stations can be reduced from four to three. or,
Since the number of the sector type antennas 202 can be three as shown, the number of one set of the TDMA unit 207, the modem 208 and the transmitting and receiving unit 209 can be reduced from four to three as shown.

Here, the same demand may have an arbitrary range, and a similarity or related demand may be regarded as the same demand by setting a wide range of the sameness. And

As described above, according to the present embodiment, a system having a user accommodating capacity that can withstand practical use can be realized on a smaller scale.
Simplification can be achieved.

The control channel slots A to E allocated for the mobile terminal device of E instruct to acquire the information of the user channels A to E, respectively.

Here, in the base station apparatus, the demands issued by the users A and B are the same, that is, the information transmitted from the base station apparatus to the users A and B is the same.
, The user channels A and B are only one user channel A ′, and the control channel slot A
And B both indicate to obtain information for user channel A '.

Similarly, when the base station analyzes that the demands issued by user C, user D, and user E are the same, user channels C, D, and E become one user channel C ′. Control channel slots C, D, E
All direct user channel C 'information to be obtained.

As described above, also in the present embodiment using the FDMA system, the same information is not repeatedly transmitted on the downlink radio channel, and the same is applied to the portable terminal device which is the mobile station requesting the same information. By instructing to look at the user channel, the frequency can be used efficiently, so that the free space of the user channel (Δ
f) and the number of users that can be accommodated can be increased.

Next, the configuration of the base station apparatus of the electronic newspaper communication system according to the present embodiment will be described using FIG.

The base station apparatus comprises a main body section 401 and a sector type antenna section 402, which is connected to the backbone network via an ATM line 403 by wire, and wirelessly connected to a mobile terminal apparatus 404 as a mobile station via the antenna section 402.

The main unit 401 includes a network I / F unit 405 for receiving an ATM line 403 from the backbone network, and an MU for distributing a line to a sector antenna corresponding to the position of the user for each communication.
An X unit 406, an FDMA unit 407 for frequency division multiplexing the signals of the allocated lines, a modulation / demodulation unit 408 for performing a modulation process on a transmission signal and a demodulation process on a reception signal, and a transmission / reception unit 409 for transmitting / receiving a radio signal. , A control unit 410 for controlling the operation of each unit, and a line control unit 411 for managing transmission and reception of signals.

When a plurality of users issue the same demand within a short time, the MUX unit 406 analyzes that the issued demands are the same, and informs the line control unit 411 to that effect. The line control unit 411 transmits a plurality of mobile terminal devices 404 that have issued the same demand on the downlink wireless line.
Are assigned to the same channel as already described with reference to FIG. Thus, the plurality of portable terminal devices 404 that have issued the same demand can receive the same information.

[0113] The control unit 410 controls the plurality of portable terminal devices 40.
4 generates a common demand signal from the same demand transmitted from the ATM line 403 from the network I / F unit 405.
To the server of a mass communication company (not shown) that provides information. The server of the mass communication company that has received the demand transmits information corresponding to the demand.

As described above, in this embodiment, the frequency can be used efficiently, so that the number of users that can be accommodated can be increased as in the first embodiment.

Further, since the compression effect of the user channel according to the present embodiment is the same as that of the first embodiment, each base station can change the service area from the conventional four directions to three directions, and Since the arrangement is a geometric arrangement in which there is no azimuthally opposed antenna, the problem of the arrangement determination using frequency repetition is reduced. That is, since the main axes of the directivity of the opposed antennas are arranged with a shift of 30 degrees,
The number of base stations can be reduced from four to three. or,
Since the number of the sector type antennas 402 can be three as shown, the number of one set of the FDMA unit 407, the modulation and demodulation unit 408, and the transmission and reception unit 409 can be reduced from four to three as shown.

As described above, according to the present embodiment, a system having a user accommodating capacity that can withstand practical use can be realized on a smaller scale.
Simplification can be achieved.

Here, the same demand has an arbitrary range, and similar or related demands can be regarded as the same demand by setting a wide range of the sameness. And

In addition to the description in the first and second embodiments, a code division multiple access system (Code Division) is used.
on Multiple Access;
A) or orthogonal frequency division multiplexing (Orthogon).
al FrequencyDivision Multi
ixing (hereinafter, referred to as OFDM) may be used.

(Embodiment 3) A base station apparatus according to Embodiment 3 of the present invention has a configuration similar to that of Embodiment 1, except that the same demand is issued from a plurality of portable terminal apparatuses. Is determined not by the base station but by the server of the provider that provides the information.

As described in the first embodiment, when each base station analyzes the demand from the user and controls the downlink radio communication, the base station uses a database or software for analyzing the demand. , And various keywords used as a reference when analyzing the demand contents must be updated daily. Employing such a configuration causes an increase in the size and cost of the base station apparatus.

In the present embodiment, since the base station does not analyze the demand content from the user and controls the downlink radio communication, the base station needs to be equipped with a database or software for analyzing the demand content. Absent.

Hereinafter, the base station apparatus and the information provider server according to the present embodiment will be described with reference to FIG. FIG. 5 is a principal block diagram showing a schematic configuration of a base station apparatus and an information provider server according to Embodiment 3 of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description is omitted.

Each base station apparatus and a server 501 of an information provider such as a mass communication provider include a network I / F section 502 for receiving an ATM line 103 from a backbone network, and a communication control section 503 for controlling and managing communication. And a user authentication unit 504 for determining whether the user who issued the demand is a contractor for providing information, and a user location for determining which base station the user who issued the demand is communicating with. A management unit 505, a user / demand analysis unit 506 for analyzing demand from a user, a CPU 507, a communication memory 508, a management memory 509, an information memory 510 for storing newspaper information such as news, LAN-I / F section 511 for receiving a LAN line, and bus 5 connecting these
12.

The content of the information memory 510 is the
Through, it is updated to the latest information at any time.

When a plurality of users issue the same demand within a short time, the identity of the demand is not analyzed in the base station apparatus, except that the line control unit 211 indicates the position indicating the position of the base station in each demand. The information is added and sent to the server 501 via the ATM line 103 and the exchange 513 as separate demands.

The demand call from the base station apparatus reaches the server of the mass communication company that provides the requested information according to the content of the demand. The demand received by the network I / F unit 502 is
Through the bus 512, it is determined from the portable terminal device ID information added to the demand by the user authentication unit 504 whether or not the demand caller is a contractor.

If it is determined that the demand caller has a contract for providing information with the mass communication company, then demand analysis is performed. The demand includes ID information (user information) of the mobile terminal device.
And base station information indicating which base station apparatus is called from within the service area, the user demand analysis unit 506 determines the demand by ID information and base station information. Organize in a two-dimensional matrix with information.

One axis of the two-dimensional matrix is composed of keywords prepared in advance according to the latest news / broadcast information, and the other axis is base station information or base station address.

The user demand analysis unit 506 determines whether or not the demand contains an error, and notifies the calling portable terminal device if there is an error. It also manages the arrival order of demand. In this arrival order management, the matrix is divided by a predetermined time window, and within each time window, it is confirmed whether or not there is a demand call from a plurality of portable terminal devices for each demand type.

Further, it is assumed that adjacent cells in the matrix have similar demands, and that a demand in an arbitrarily defined range in the matrix is collected in a cell located at the center of the range. Is also good.
This is synonymous with arbitrarily setting the sameness range as described above.

The demand that has been arranged and integrated is decrypted, and the corresponding newspaper information is read from the information memory 510. The information memory 510 may be separately provided outside the apparatus.

The read information is stored in the communication memory 508.
And waits for transmission timing.

The communication control unit 503 receives the demand arrival order from the user demand analysis unit 506 and transmits the demands in order from the first-come-first-served demand. At this time, if there is a demand from a plurality of users, a multicast command is added to the newspaper information. The multicast command includes user information of a destination to be broadcast.

The base station apparatus 201 receives newspaper information via the ATM line 203 and the exchange 513.
The newspaper information is transmitted from the antenna 202 to the designated destination. When the multicast command is added to the newspaper information, it is transmitted to a plurality of portable terminal devices. The transmission method is as described above.

Upon receiving the notification that the newspaper information has arrived safely at the portable terminal device, the user authentication section 504 performs a billing process for the user.

The newspaper information stored in the information memory 510 of the server 501 includes the local LAN and the LAN-I /
Through the F unit 511, constant writing is performed so as to be updated to the latest information.

As described above, according to the present embodiment, since the analysis of the demand is performed in the server of the mass communication company, the configuration of the base station apparatus can be simplified, and the size and cost can be reduced. Can be planned.

(Embodiment 4) An electronic newspaper communication system according to Embodiment 4 of the present invention has a configuration similar to that of Embodiment 1, except that a portable terminal device uses a typical usage pattern of a user. It learns and automatically performs demand calling regardless of the demand calling operation from the user.

As described above, since it is considered that there are many business people on the way to commuting to the electronic newspaper, the usage patterns of many users are considered to be customary. Therefore, in the present embodiment, the portable terminal device learns a typical usage pattern of the user, and customarily requests the same information required in the same time zone, for example, between 8:00 am and 8:10 am For example, the mobile terminal device automatically generates a demand call in advance of, for example, 8:00 am in the above example without waiting for the user to perform a demand call operation such as “main news” and “weather forecast”. To do it.

The typical usage pattern of the electronic newspaper referred to here is, for example, “Usage fields (politics, economy,
), "Usage information-related regions (Domestic, Europe, Asia,
Etc.), "Issue date of usage information", "Usage time", "Usage time", "Usage day", "Usage order (from power ON to O
FF), and “total number of times each piece of usage information is used”.

Hereinafter, an electronic newspaper communication system according to the fourth embodiment will be described with reference to FIGS. FIG.
FIG. 7 is a main block diagram showing a schematic configuration of a portable terminal device of an electronic newspaper communication system according to Embodiment 4 of the present invention. FIG. 7 is a diagram illustrating use of the electronic newspaper communication system according to Embodiment 4 of the present invention. FIG. 8 is a schematic diagram illustrating an example of a pattern distribution, and FIG. 8 is a schematic diagram illustrating a configuration of a demand of the portable terminal device according to Embodiment 4 of the present invention.

In FIG. 6, a portable terminal device 601 includes an antenna unit 602 for acquiring a radio signal, a radio unit 603 for performing radio processing, a modulation / demodulation unit 604 for performing modulation / demodulation, and a code / code for performing encoding and decoding. A decoding unit 605, a hard disk (hereinafter, referred to as an HDD) 606, a memory 607, for example, a flash memory, a memory control unit 608 that controls recording / reading to / from the memory 607, and controls the entire portable terminal device 601. CPU / DSP unit 609
A display / operation unit 610 for displaying information such as characters, still images, and moving images, and performing operations such as menu selection by a user; a speaker unit 611 for outputting audio information; and a microphone unit 612 for inputting audio information. An input / output I / F control unit 613 for controlling the input / output of information to / from the display / operation unit 610, the speaker unit 611, and the microphone unit 612; a control bus 614 for sending control signals to these units; A data bus 615 for transmitting information;
And a power supply section 616 for supplying power to the entire device.

Next, the operation of the portable terminal device according to the present embodiment will be described using FIG. The user normally performs a demand calling operation using the display / operation unit 610. The CPU / DSP unit 609 obtains a history of demands transmitted from the portable terminal device and stores the history in the HDD 606. Further, the CPU / DSP unit 609 includes the HDD 606
Analyze usage patterns from demand history stored in
Make a demand call automatically.

A method of analyzing a usage pattern will be described below with reference to FIG. FIG. 7 shows “field”, “region”,
This is an example of a case where a usage pattern is analyzed from a demand history of a user using three parameters of “time series”.

[0145] X ₁ axis indicates the sector code representing the Field of information requested by the user by demand calling,
It shall consist of the items as shown. Similarly, X ₂
Axis region code that indicates information about which local information is requested, X ₃ axis shows sequence code when the requested information is indicate when the information, respectively.

Here, the usage pattern shown in FIG. 7 will be described. The user first calls demand A,
Accessed information on "music and culture" in "Europe" in "Today." Next, call demand B, access information on "industry" in "Europe" of "today", and in demand C in order of "Africa" of "today" in the following order.
Information on “industry” in Demand D
Within months, information on "Africa" and "Industry" was accessed.

[0147] Such "demand history A → B → C →
D ", that is, the code (X₁, X_Two, X _Three) And access
Is stored as one usage pattern.

The items in each code may be arbitrarily determined even if they are not shown, and the codes are not limited to three types.

[0149] Next, referring to FIG.
A description will be given of a configuration of a demand when 1 issues a demand based on a usage pattern.

When the portable terminal device 601 makes an automatic call based on the usage pattern, the portable terminal device 601 needs to transmit to the base station device as shown in FIG. , A time stamp 802 indicating the demand calling time, and codes X _{1 to} X _n 803 which are information on n types of parameters.
, An article code 804 which is an article ID, a media code 805 indicating which media the article belongs to, and a heading / title 806 indicating the selected heading / title.

However, transmitting such a large amount of information in demand calling requires a large amount of memory capacity for the portable terminal device 601, and therefore, in this embodiment, as shown in FIG. Adopt a demand structure.

That is, the portable terminal device 601 creates a demand as shown in FIG. 8E from the usage pattern of the user. The article code-code classification table 807 stored in the HDD 606 in advance based on the code 803 and the time stamp 802 in such a demand.
Is used to convert the code 803 into the corresponding article code 804.

In this manner, a demand call can be made with a signal as shown in FIG. 8B, which is shorter than FIG. 8A.

The portable terminal device 601 analyzes the accumulated results of demand calls by the user, learns usage trends, and accumulates the data as usage pattern data. For example, for the user Y who is set to automatically call his / her own mobile terminal device, the user looks at the “domestic / main news (code)” of “XX news (media)” every morning from 7:00 am If the usage pattern of “Sports (code)” of “△△ Newspaper (media)” to be viewed from 7:05 is obtained as a result of the analysis, the portable terminal device of the user Y must be ready by 7:00 am "Domestic / Main News" of the latest "XX News"
Is received before 7:00 a.m.
○ Automatically calls a demand requesting “domestic / main news” of “news”. Similarly, the latest “Sports” of “△△ Shimbun” is received before 7:05 am, as the latest “Sports” of “△△ Newspaper” is received by 7:05 am Automatically call the demand you request.

As described above, according to the present embodiment, if a user views an electronic newspaper according to a daily use pattern (time, information type, order), a demand call operation becomes unnecessary, and Since the waiting time for downloading the information to the portable terminal device does not occur, the convenience for the user is improved.

[0156] When the user uses the user in accordance with a daily pattern, if the user's position is in an environment where the radio wave condition is not good, the information can be received in advance in a good environment. It is possible to watch an electronic newspaper under any radio wave environment at the usage time according to a daily pattern.

Further, assuming that the electronic newspaper is intensively used in a time zone determined by a business person or the like, for example, from 7:00 am to 8:00 am, by receiving information in advance, the peak can be obtained. -Traffic can be reduced.

(Embodiment 5) An electronic newspaper communication system according to Embodiment 5 of the present invention has a configuration similar to that of Embodiment 4, except that the portable terminal device is located substantially before the requested information arrival time. In this case, the base station apparatus can select and transmit a time when traffic is vacant by making a demand automatic call.

The effect of peak traffic mitigation by the automatic call demand of the portable terminal device cannot be obtained depending on the traffic situation in the shifted time zone.
For example, with respect to the user X who has a habit of reading “main news” during peak traffic (here, 8:00 am), the mobile terminal device of the user X is analyzed at 7:55 am by analyzing the usage pattern of the user X. , A demand requesting for “main news” is automatically issued, and when the user X looks at the mobile terminal device at 8:00 am, “main news” is already displayed. This will contribute to traffic mitigation at 8:00 am, but all portable terminal devices requesting information by 8:00 am will have a uniform shift amount, that is, all mobile terminals will automatically demand at 7:55 am If a call is to be made, the traffic simply shifts in bulk, does not provide the effect of dispersion, and does not contribute to alleviating peak traffic generated in the system.

Therefore, in the present embodiment, the portable terminal device to which the automatic call is set is made to make the automatic demand call considerably before the time when the information is required, for example, three hours before. Further, the traffic congestion degree of the base station apparatus is determined by a service control node (Service Controller).
ol Point; hereinafter referred to as SCP), and when traffic in the wireless communication section of each base station device is free, information is sent from the server of the mass communication company to each base station device and transmitted to the portable terminal device.

Hereinafter, the electronic newspaper communication system according to the present embodiment will be described with reference to FIG. FIG. 9 is a main block diagram showing a schematic configuration of an electronic newspaper communication system according to Embodiment 5 of the present invention. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The SCP 901 can grasp the traffic in each exchange 513. Further, since each traffic is accompanied by a destination, that is, information to be transmitted to which mobile terminal device 204 in which base station device 201, the SCP 901 determines the traffic in the wireless communication section in each base station device 201. Can be grasped.

Here, it is assumed that the portable terminal device 204 automatically makes a demand call to provide information from 7:00 am based on the usage pattern of the user. If this automatic call is made not immediately before 7:00 am but rather before, for example, 4:00 am, the base station apparatus 201 measures the time period during which traffic is available between 4:00 am and 7:00 am Information can be transmitted to the portable terminal device.

As described above, according to the present embodiment, in prior information reception by automatic calling, traffic in the time zone of the shift destination can be dispersed, so that peak traffic can be reduced.

In this embodiment, base station apparatus 20
1 accumulates the traffic history of its own wireless communication section,
This can be notified to the portable terminal device to distribute the traffic on the portable terminal device side.

In other words, in response to a demand called before the information provision time by the automatic call of demand, the base station apparatus cannot transmit information to the portable terminal apparatus at present because traffic is congested and the base station apparatus cannot transmit the information. The average and daily traffic history in the station device is sent back. The mobile terminal device selects a time zone during which traffic is available from the received traffic history and re-executes the demand automatic call.

For example, when the portable terminal device makes a demand call for providing information from 7:00 am at 4:00 am,
When a retransmission instruction is sent back together with the traffic history from the base station device, the mobile terminal device determines, based on the received traffic history of the base station device, a time period during which traffic to be demanded next is available, for example, 5:00 am And wait until that time. At that time, the demand call is re-executed. This operation can be performed repeatedly.

(Embodiment 6) An electronic newspaper communication system according to Embodiment 6 of the present invention has a configuration similar to that of Embodiment 5, except that the degree of congestion in a wired communication section is taken into account.

[0169] Even in a time zone when the traffic in the wireless communication section in the base station apparatus is vacant, the server of the mass communication company transmitting the actual information may be congested. In addition, it is considered that a user often moves during use, and a base station device that performs wireless communication also changes. Therefore, only traffic information of one base station device does not contribute to alleviation of peak traffic in the entire system.

Therefore, in the present embodiment, when the portable terminal device makes an automatic call for demand, not only the traffic related to the wireless communication of the base station device as the wireless communication partner, but also the
Consider the degree of congestion of the server of the mass communication company that is the information provider.

Hereinafter, the electronic newspaper communication system according to the present embodiment will be described using FIG. 10 and FIG.
FIG. 10 is a main block diagram showing a schematic configuration of a portable terminal device of an electronic newspaper communication system according to Embodiment 6 of the present invention. FIG. 11 is an electronic newspaper communication system according to Embodiment 6 of the present invention. 6 is a table showing the degree of traffic congestion held by the portable terminal device of FIG. The same components as those of the fourth embodiment are denoted by the same reference numerals, and the detailed description is omitted.

In FIG. 10, traffic information extraction / storage section 1001 includes traffic history of the base station apparatus transmitted from the base station which is the wireless communication partner, and congestion of the server transmitted from the server of the mass communication company. Are extracted from the received signal and stored. Details will be described later with reference to FIG.

The user behavior pattern recognition unit 1002 stores the user's usage pattern as described above. Each time the mobile terminal device is used, the usage pattern is updated with a learning result including a new usage history.

The call scheduler 1003 sets up a demand call schedule based on the usage pattern of the user, the congestion degree of the base station device, and the congestion degree of the mass communication service server. The line monitoring unit 1004 monitors traffic with the base station device.

FIG. 11 shows a traffic information extraction / storage section 1.
001 is an example of a table showing the history of the congestion degree of the base station devices B _{1 to} B _n and the mass communication providers (media) M _{1 to} M _k for each time zone held by 001.

In the above table, based on the past usage history,
It indicates at what time zone communication with each base station device and each medium is busy, traffic conditions and day-of-week variation factors.

By taking such a history, it is possible to learn which base station device is vacant in which time zone and in which time zone each media is vacant. Therefore, according to the present embodiment, the portable terminal device can perform the automatic call of demand by selecting the time when the traffic is free, and can efficiently distribute the traffic by the prior call.

(Embodiment 7) An electronic newspaper communication system according to Embodiment 7 has the same configuration as that of Embodiment 6, except that a wired communication section from the base station apparatus to the mass communication company server is provided. The degree of congestion is also taken into account.

Hereinafter, the electronic newspaper communication system according to the present embodiment will be described with reference to FIGS. FIG. 12 is a main block diagram showing a schematic configuration of an electronic newspaper communication system according to Embodiment 7 of the present invention.

FIG. 6 is a schematic diagram showing an example of a use route history grasped by a user. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description is omitted.

An SMS 1202 is provided in a radio apparatus 1201 connecting the network 1203 and the base station apparatus 201. The network 1203 is provided with a wired access network 1204, and the server 5 of the mass communication company is provided.
01 is connected.

Here, the S provided in the wireless device 1201
The MS 1202 can grasp the congestion degree of the network 1203 by reading the line congestion information carried in the ATM RM cell described later.

FIG. 13A is a schematic diagram showing the structure of a normal ATM cell. A normal ATM cell consists of a 5-byte header and 48 bytes of user information. FIG.
(B) is a schematic diagram showing a detailed structure of a normal ATM cell. In a normal ATM network, line congestion information is transmitted using a PT (payload identification) in a header.

FIG. 13 (c) shows an example of A used in this embodiment.
TM Resource Management Cell (Resource)
FIG. 2 is a schematic diagram illustrating a configuration of a ce Management Cell (hereinafter, referred to as an RM cell). When using PT, only 0 or 1 can be sent, so there is little information on the degree of circuit congestion. However, since there is a lot of information that can be sent using RM cells, detailed information on the degree of circuit congestion should be transmitted. Can be.

That is, it is possible to know which route is congested in the wired communication section from the base station apparatus to the mass communication company server.

The advantage of grasping the above route will be described with reference to FIG. In FIG. 14, it is assumed that the user A is using the electronic newspaper communication system while moving from 6:00 to 8.30, and for this information, an automatic call for demand is set.

[0186] Here, for example, 7:40 to 8:00 between the assuming that can not receive information from routinely switching center C ₁₀ has crowded and media A is previously known from the history, the user A 7: 40-8: 00
Information was trying to you were trying to demand and receive a call during (e.g. 8:00 to 8:30 information used by the user during) the user A is within the service area of the base station B ₇ .about.B ₁₀ You can call or receive in advance while you are there.

As described above, according to the present embodiment, not only the congestion degree of the wireless communication section and the mass communication service server by time, but also the history of the path information by time and the congestion degree of the route are taken. Thereby, the portable terminal device can efficiently select and execute the demand automatic call when the line is free, and can distribute the traffic.

Conversely, if it is inferred from the user's usage pattern and the degree of line congestion that the line is vacant even immediately before the use time, the portable terminal device issues a large amount of demand in advance in a lump. There is no need to receive and accumulate a large amount of newspaper information and only make the required demand call immediately before the required time. Therefore, traffic is dispersed, peak traffic is reduced, and mobile terminals are further reduced. The HDD and the memory mounted on the device can be reduced in size and weight.
