Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information distribution system for distributing digital information such as music, images, characters, and the like to portable terminals of respective users, and to the portable terminals.

[0002]

2. Description of the Related Art In recent years, music, video, text information, and the like are distributed to personal terminals through communication lines due to advances in digital processing technology, downsizing and high performance of information communication / reproduction devices, and diversification of communication means. Information distribution systems are being put to practical use. Among such information distribution systems, those that are already in practical use include, for example, an information distribution service by a vending machine, a demonstration test of which was started by JR West on September 1, 1999, and a broadcast using a satellite. Digital information distribution. The information distribution service by the vending machine is a service in which digital data such as music content is stored in a vending machine installed in a station or the like, and desired information is directly written into a memory card of a purchaser.

[0003]

However, these existing information distribution services have the following problems. First, the information distribution service by the vending machine directly downloads the information to the user's memory card inserted in the vending machine, so that the information can be distributed as desired by the user. There is a problem that a vending machine can provide service to only one user at a time. Therefore, for example, even if a plurality of users desire the same information, they cannot be distributed to all at the same time, and it is necessary to form a queue and distribute sequentially. In this case, no matter how fast data can be downloaded, information cannot be provided to a large number of users in a short time, and there is a practical problem. Another problem is that the user must go to the vending machine to perform cumbersome operations such as inserting and removing a memory card. Further, there has been a problem that mechanical troubles such as poor contact of the connector portion with the memory card easily occur. On the other hand, the broadcast-type digital information distribution using the satellite has the advantage that information can be transmitted to a large number of users in a wide range at the same time, but the information distribution is performed according to a predetermined distribution schedule. There is a problem that the received information does not always meet the user's wishes. That is, the user cannot obtain desired information when he / she likes. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information distribution system and an information distribution system capable of efficiently distributing information that meets the wishes of each user without troublesome operations. To provide a mobile terminal used for receiving the information.

[0004]

To achieve the above object, a first aspect of the present invention is an information distribution system for wirelessly distributing information from one base station to a plurality of portable terminals. The terminal detects that the terminal has entered the wireless communication area of the base station, and transmits predetermined information to the base station. The base station is configured to transmit the predetermined information based on the predetermined information received from the portable terminal. Recognize the mobile terminals that have entered the wireless communication area, and in accordance with a distribution schedule organized based on the recognized mobile terminals or the preference information of the owner, the mobile terminals within the wireless communication area are recognized. The information transmission system is characterized by transmitting information all at once. In this way, by distributing information in a broadcast format using wireless communication, information can be transmitted to a plurality of users who request the same content without a queue like conventional one-to-one information distribution. It is possible to distribute information to a plurality of users at the same time, and to distribute information according to a distribution schedule organized based on preference information of portable terminals existing in the wireless communication area of the base station. Nevertheless, it is possible to perform information distribution that meets the needs of individual users existing in the communication area with the base station from time to time. In addition, since wireless is used as a communication means, the mobile terminal automatically detects information when it enters the wireless communication area of the base station and automatically receives information. There is no need to perform cumbersome operations such as connection.

[0005] Further, as a mechanism for obtaining preference information on a portable terminal that has entered the wireless communication area of the base station on the base station side, for example, the predetermined information transmitted by the portable terminal includes the portable terminal or its owner. If the preference information for each portable terminal or each owner thereof is registered in advance in the base station or in a server capable of communicating with the base station, the base station or the server Can obtain preference information about the mobile terminal based on the identification information received from the mobile terminal.
At this time, the registration of the preference information is performed by, for example, the portable terminal,
This can be performed via the Internet, a public line, or the like. Another mechanism for the base station to obtain preference information about the mobile terminal that has entered the wireless communication area of the base station is that the predetermined information transmitted by the mobile terminal includes the mobile terminal or the owner of the mobile terminal. It is also conceivable to include preference information. This makes it possible to reduce the processing load when searching for preference information on the base station side and the communication load when transmitting preference information in the server to the base station.

[0006] Further, the base station transmits specific information with the identification information of the specific mobile terminal added thereto based on a request from the specific mobile terminal or its owner. If the specific information can be reproduced only when the own identification information and the identification information added to the specific information match, the specific information distributed to the specific mobile terminal can be It can be prevented from being reproduced on other portable terminals. As a result, the same function as one-to-one information distribution can be achieved at the same time while taking the form of broadcast-type information distribution. At this time, if the identification information added to the specific information does not match the identification information of the portable terminal, the portable terminal may be configured to discard the received specific information, for example. Here, the request for the specific information can be input in advance via the Internet or a public line, and the base station transmits the request for the specific information to the mobile terminal in a state where the request for the specific information is input. If the specific information is transmitted when the user enters the communication area, the user sets a request for the specific information in advance so that the user enters the wireless communication area of the base station next. Sometimes, the information can be automatically obtained without any operation, which is convenient.

Further, the base station is provided with input means for inputting the request for the specific information, and the base station receives the request for the specific information from the input means when the request for the specific information is input from the input means. It is configured to perform transmission, or the request for the specific information can be input via the portable terminal, and the base station receives the request for the specific information via the portable terminal when the request for the specific information is input. If the system is configured to transmit specific information, the user can immediately receive the desired information by inputting the desired information from the base station or the mobile terminal, and use the conventional vending machine. The same function as information distribution can be realized. However, since information is received wirelessly, it is not necessary to perform cumbersome operations such as connecting devices with a connector as in the related art.

[0008] The accounting information for each mobile terminal is generated based on the predetermined information received from the mobile terminal by the base station and a transmission result of information transmitted corresponding to the predetermined information. However, in order to perform accurate billing, it is necessary to confirm that the transmitted information is normally received by the portable terminal. As a method of this confirmation, the predetermined information transmitted by the mobile terminal includes:
It is possible to include a record of reception of information normally received in the past or a record of reproduction of such information, and charge based on the record of reception or the record of reproduction received by the base station. Conceivable. As a result, it is possible to solve the drawback of the conventional broadcast format information distribution in which it is impossible to confirm whether the information transmitted from the base station has been normally received by the portable terminal side, and to perform the accounting process correctly. Further, the portable terminal sets the priority of storing the information received from the base station in the memory, for example, as the distance between them becomes smaller, based on the preset preference information and the attribute information of the information. With this setting, it is possible to automatically exclude information that does not match the user's preference information, thereby improving the convenience of the user in reproducing the information and effectively using the limited storage capacity. It is possible.

[0009] A second invention is a portable terminal constituting the information distribution system according to the first invention.

FIG. 8 is a flowchart showing a distribution schedule determining process performed by the schedule generating unit 13. FIG. 8 is an explanatory diagram of a specific example of a distribution schedule determining process performed by the distribution schedule generating unit 13. FIG. FIG. 1 is a flowchart showing a processing procedure for extracting content management information of each content data, FIG.
0 is an example of a content table generated by the processing shown in FIG. 9, and FIG. 11 is an example of management information on distribution content in the charging information management server 3 c.

[0011] Information distribution system Z1 according to the present embodiment
Is composed of a portable terminal 2, a base station 1, and a server 3, as shown in FIG. Further, the portable terminal 2 and the base station 1 further have a schematic configuration as shown in FIG. As shown in FIG. 1, a plurality of base stations 1 installed in places where people gather, such as stations, are connected to the server 3 by, for example, a dedicated communication line 4. The base station 1
ISM (Industrial, Scientific, Medical) band (frequency band open to industrial, scientific and medical equipment, 2.4 GHz
z, 10 mW or less), and each has a wireless communication area with a radius of about 50 m. The mobile terminal 2 is a terminal carried by a user registered in advance, and is capable of high-speed wireless communication with the base station 1 within the wireless communication area of the base station 1. The configurations of the server 3, the base station 1, and the mobile terminal 2 will be described in more detail.

(Server 3) As shown in FIG. 1, the server 3 comprises a user information management server 3a, a content server 3b, and a billing information management server 3c. The server 3 may be physically composed of one computer or a plurality of computers. Here, in the content server 3b, various content data to be delivered to the user are stored in a compressed state by a predetermined method. Examples of the type of content data to be stored include image contents such as still images and moving images, music contents and their composite contents, and character / audio contents such as news. Various information sources for these content data, such as digitalized analog audio such as the Internet, music CDs, and FM broadcasts, can be considered. Also, for example, Text-t
It is also possible to generate audio content from text documents using o-speech. When the content data is audio information such as music, the compression method used in the encoding device 4 is TwinVQ, MP3, AA.
C, WAV, etc. can be used. The content server 3b stores attribute information of each content data together with each content data. Here, the attribute information is set by the degree of relevance to each “attribute”. The "attribute" is a proposition related to the content, such as "news" or "classical music". The attribute value indicates the degree of relevance to the proposition. Is given as an integer. For sports news content data,
For example, attribute values of attributes such as "news" and "sports" are set to, for example, 60, 40, and the like.

The user information management server 3a stores preference information of all registered users in advance. Like the attribute information of the content data, the preference information is set based on the degree of applicability to a plurality of “attributes”. For example, the preference information of a user who wants “news” and “classical music” is, for example, “news” and “classical music” are 50 and 50, respectively, and other “JPO”.
“P”, “Western POP”, etc. are set to 0. The user information management server 3a further stores individual distribution request information from a user who wants to distribute individual content data. The individual distribution request information is not specifically set for each genre (attribute) such as the above-mentioned preference information, but is specifically set in the form of, for example, a predetermined song of a certain singer. Here, it is desirable that the preference information and the individual distribution request information can be made in advance from the user's home or the like via the Internet or the like. The charging information management server 3c manages charging information for each user. For example, it is conceivable that the user is charged within a fixed amount for normal distribution based on the preference information, and an additional charge is added to each distributed content data for individual distribution according to the individual distribution request. . The details of the billing process will be described later.

(Base Station 1) As shown in FIG. 2, the base station 1 includes a communication control unit 11, a content data storage unit 1
2, a distribution schedule generation unit 13 and a transmission / reception unit 14 are provided. The communication control unit 11
Controls communication with the server 3. The content data storage unit 12 stores, for example, content data periodically transferred from the content server 3b and attribute information thereof. The content data transferred from the content server 3b to the content data storage unit 12 is selected in consideration of, for example, distribution results for each base station. For example, to a base station where the distribution of classical music is large and the distribution of pops is small, a large amount of content data belonging to classical music and a small amount of content data belonging to pops are transmitted in accordance with the distribution results. 12 is stored.

The distribution schedule generating unit 13
Recognizes the mobile terminal 2 which is in a state where information can be received at the present time based on the identification ID (details will be described later) transmitted from the mobile terminal 2 which has entered the wireless communication area of the base station 1 and , And acquires the user preference information corresponding to the identification ID from the user information management server 3a. Then, a distribution schedule of the content data is generated based on the attribute information of each content data stored in the content data storage unit 12 and the user preference information. In this way, the portable terminal existing in the limited wireless communication area having a radius of about 50 m is recognized, and the distribution schedule of the content data is generated based on the preference information preset for each portable terminal. The distribution schedule according to the present invention is more suitable for the user's preference of each portable terminal than the conventional distribution schedule for broadcasting information in a wide area. Also, in the user information management server 3a,
When the individual distribution request information corresponding to the received identification ID is registered, the content data set in the individual distribution request information is incorporated into the distribution schedule prior to the preference information. A specific example of the distribution schedule generation processing will be described later. When the distribution schedule is determined, the distribution schedule generator 13 generates transmission data according to the distribution schedule. This transmission data is composed of content data and management information of the content, as shown in FIG. The content management information includes a title of the content, the attribute information,
It is composed of an identification ID of a mobile terminal capable of receiving the transmission data. Here, the identification ID of the portable terminal that can receive the transmission data is the identification ID of the portable terminal of the user who registered the individual distribution request if the content data is based on the individual distribution request information.
For example, "AX0123" and "BG5590" are set. If the content data is not based on the individual distribution request information, a special identification ID indicating that the content data can be received by all portable terminals, for example, "XX"
0000 "is set.

The transmitting / receiving unit 14 controls wireless communication with the portable terminal 2. When the portable terminal 2 receives distribution request data (see FIG. 6 and details will be described later) transmitted when the mobile terminal 2 enters the wireless communication area of the base station 1, the transmission / reception unit 14 generates an interrupt and outputs the distribution request. The identification ID in the data is transmitted to the distribution schedule generation unit 13 and the reproduction result record is transmitted to the charging information management server 3c. The transmission data transmitted from the distribution schedule generation unit 13 is transmitted to each mobile terminal 2. Here, as shown in FIG. 5, the transmission data is divided into fixed-length frames, and a header portion including frame information (the number of all frames) and an error detection code such as a CRC is added. Sent out. When the transmission data is transmitted, the distribution result (for example, the portable terminal ID of the distribution partner, the ID of the distributed content data, the distribution date and time, etc.) is stored in the charging information management server 3c, and is used in the charging processing described later. Can be The content data is compressed using TwinVQ or the like as described above, and data transmission from the base station 1 to the portable terminal 2 is performed at high speed (for example, 5M) using the ISM band.
bps, a maximum of about 11 Mbps), for example, a 30-minute news voice can be transmitted to a portable terminal in about 4 seconds and a 5-minute music can be transmitted in about 5 seconds. Therefore, the mobile terminal 2
Is capable of receiving a sufficient amount of content data while staying in a wireless communication area having a radius of about 50 m. Of course, since it is distributed to each portable terminal simultaneously in a broadcast format, there is no waiting time.

(Portable Terminal 2) As shown in FIG. 2, the portable terminal 2 includes a transmitting / receiving unit 21 and a temporary data storage unit 2.
2, data storage medium 23, playback module 24, I
It comprises a D storage unit 25, a content storage module 26, a preference information storage unit 27, and a playback result record storage unit 28. Here, the data storage medium 23
It is preferable to use a removable nonvolatile memory such as a smart media or a compact flash, but it is also possible to use a built-in flash memory or a DRAM, for example. The temporary data storage unit 2
Reference numeral 2 is composed of two areas, a reception data buffer and a content table data buffer. The transmission / reception unit 21 controls wireless communication with the base station 1.
When processing such as restoration and reproduction of received data, which will be described later, is not performed, the transmission / reception unit 21 enters a radio wave standby state. When a radio wave from the base station 1 is detected in this standby state (that is, when it is detected that the portable terminal 2 has entered the wireless communication area of the base station 1), the ID stored in the ID storage unit 25 in advance is stored. The distribution request data (see FIG. 6) composed of the identification ID of the portable terminal (or the user) and the reproduction result record (described later) stored in the reproduction result record storage unit 28 is transmitted to the base station 1. After the transmission, the reception of the transmission data transmitted from the base station 1 is started, and the reception is sequentially stored in the reception data buffer of the temporary data storage unit 22. As a method of detecting that the mobile station has entered the wireless communication area of the base station 1, for example, a digital value of the electric field intensity is monitored by an electric field intensity detection circuit, and the electric field intensity value and its statistic (average, It is conceivable that when the predetermined evaluation value based on the variance or the like exceeds the threshold value, it is determined that the mobile station has entered the wireless communication area of the base station 1 (that is, communicable with the base station 1). Further, an error check is performed using an error detection code such as a CRC flag embedded in a header portion of data received from the base station 1, and when it is determined that there is no error, it is determined that communication with the base station 1 is possible. You may.

From the transmission data sequentially stored in the reception data buffer of the temporary data storage unit 22, the content storage module 26 pre-sets the preference information storage unit 27 for each content data for which all frames have been normally received. The storage priority is determined based on the user preference information and attribute information of each of the content data set as described above, and the content data is stored in the data storage medium 23 according to the priority. As described above, the content data transmitted from the base station 1 is distributed according to the distribution schedule determined based on the preference information of the portable terminal 2 existing in the wireless communication area of the base station 1. Except for the content data specially distributed by the individual distribution request, not all the distributed content data completely satisfy the user's preference of the portable terminal 2. On the other hand, the storage capacity of the data storage medium 23 set in the portable terminal 2 is limited. Therefore, the content storage module 26
Within the range of the storage capacity of the data storage medium 23, processing for preferentially storing content data that matches the user's preference information as much as possible is performed. At this time, if the own identification ID is not included in the identification ID of the receivable portable terminal set in the content management information, the content data is not stored but discarded.
Thus, it is possible to prevent content data distributed to a specific portable terminal based on the individual distribution request from being stored in another portable terminal and reproduced. That is, with such a structure, the same function as one-to-one information distribution can be achieved at the same time while taking the form of broadcast-type information distribution. A specific example of the content data storage processing procedure will be described later.

The reproduction module 24 restores and reproduces content data stored in the data storage medium 23 in response to a reproduction request from a user. When the reproduction of the content data is completed, the reproduction module 24
Writes the ID of the content data in the reproduction result record storage unit 28 as the reproduction result record. That is, the content data whose ID is recorded in the reproduction result record storage unit 28 is the content data normally received and reproduced by the portable terminal 2. As described above, when the portable terminal 2 enters the wireless communication area of the base station 1, the reproduction result record is transmitted to the base station 1 together with the identification ID, so that the transmitted content is transmitted to the base station 1. It can be recognized that the data has been normally received and reproduced. The billing information management server 3c performs a billing process based on the playback record. A specific example of the accounting process will be described later.

Subsequently, the distribution schedule generation unit 1
3 will be described in detail below. (Specific Example of Procedure for Generating Distribution Schedule by Distribution Schedule Generating Unit 13) A procedure for generating a distribution schedule based on user preference information by the distribution schedule generating unit 13 will be described with reference to FIG. The distribution schedule generation unit 13 performs the user preference information set in the user information management server 3a and the identification ID of the mobile terminal (or user) currently in the wireless communication area.
Is calculated based on the current needs (S5).
3). Here, the identification ID of a user who is currently in the wireless communication area (a user who has entered the wireless communication area within a certain period of time in the past is regarded as this) is stored in a predetermined identification ID buffer by the transmission / reception unit 14. (S5
1, S52). On the other hand, the distribution schedule generation unit 13
Acquires the ID of the content distributed within the past fixed time stored in the charging information management server 3c (S6).
1) The broadcast performance distribution is calculated with reference to the attribute information of each content data stored in the content data storage unit 12 (S62). Subsequently, a difference between the user's needs distribution and the broadcast results distribution is determined, a program that minimizes the difference is selected, and a program schedule to be distributed within a predetermined time is generated (S71).

A specific example of the information distribution schedule determination process described above will be described with reference to FIG. In the figure, 1/20 is shown as the attribute value. That is, when the value is represented by an integer from 0 to 100, it is given by multiplying the value in the table by 20. In addition, the preference information of the user in the area indicates that, for the attribute 1, for example, 30 people have the attribute value "5" and 40 people have the attribute value "4". First, based on the user's preference information, Y _i is calculated by further normalizing the average value of each attribute i, and this is set as the needs distribution. Moreover, since there is no past broadcasting results in the initial state, the X _i calculated normalized values for each attribute i, respectively for each program, which is referred to as the broadcast actual distribution. Then, D = ΣMax (0, Y _i −X _i ) (a) is obtained for each program, and the program with the minimum D is the next broadcast program. In the example of FIG. 8, since D of the program 29 is 0.46, which is the minimum, the program 29 is first incorporated into the first broadcast schedule.
The following is the above-mentioned program 29 and broadcast experience program, this and other of the above broadcast proven distribution X _i calculated at each program, incorporate a program this is a minimum in the next broadcast schedule. Here, D calculated by the program 29 and the program 15 is 0.26.
, The program 15 is incorporated into the broadcast schedule following the program 29. Thereafter, the above process is repeated until a broadcast schedule within a predetermined time is determined. The distance may be D = Ｄ (Y _i −X _i ) ² ... (B). As shown in the calculation result of the program schedule shown in the lower right of FIG. 8, it can be understood that the distance between the user needs and the actual program results decreases as the program schedule advances, and the user needs are satisfied. That is, according to this method of determining a broadcast program, the user needs are complementarily satisfied by a plurality of programs that are continuously played. As described above, in order to recognize mobile terminals existing within a limited wireless communication area having a radius of about 50 m and generate a content data distribution schedule based on preference information set in advance for each of the mobile terminals, The distribution schedule to be performed is more suitable for the user's preference of each portable terminal than the conventional distribution schedule of broadcast-type information distribution over a wide area. When there is no user in the communication area, predetermined content (for example, news) may be repeatedly delivered, or a terminal that has arrived in the area may simply transmit a carrier wave for detecting that. You may keep sending.

(Specific Example of Processing Procedure by Content Storage Module 26) As described above, the content data transmitted from the base station 1 to the portable terminal 2 is transmitted to the portable terminal 2 existing in the wireless communication area of the base station 1. Are distributed in accordance with the distribution schedule determined based on the preference information of the portable terminal 2 except for the content data specially distributed by the user's individual distribution request. It may not always suit your taste. On the other hand, the storage capacity of the data storage medium 23 set in the portable terminal 2 is limited. Therefore, the content storage module 26 performs a process of preferentially storing content data that matches the user's preference information as much as possible within the storage capacity of the data storage medium 23. In addition, since the distribution of content data is performed simultaneously to multiple mobile terminals in broadcast format,
Content data transmitted to a specific mobile terminal in response to an individual distribution request is also received by another mobile terminal. Therefore, in order to prevent content data transmitted to a specific mobile terminal from being saved and reproduced by another mobile terminal, the content data of the mobile terminal other than the mobile terminal having the identification ID set in the content management information in advance is stored. Disable saving.

The processing procedure of the content storage module 26 will be specifically described with reference to FIGS. FIG. 9 shows a procedure of processing for extracting transmission data in the reception data buffer of the temporary data storage unit 22 in frame units and extracting content management information of content data in which all frames are normally received. Steps S81 to S83 show a process of writing transmission data in the reception data buffer of the temporary data storage unit 22 by the transmission / reception unit 21. First, the content storage module 26 repeats the process of reading one frame at a time from the reception data buffer of the temporary data storage unit 22 until the first frame of the transmission data is found (steps S84 to S84).
S86). If the end of the data is detected on the way, the process ends at that point. The determination as to whether or not the frame is the first frame of the transmission data can be made by referring to the frame information in the header portion. When the first frame of the transmission data is found, the content storage module 26 reads one more frame from the reception data buffer (S87). If the reading is successful (if not the end of the data), it is determined whether the frame data is correct. Judge (S88, S
89). If it is determined in step S88 that reading has failed (that is, if the end of the data is detected), the process ends at that point. If an abnormality is found in the frame data in step S89, the process proceeds to step S84. . Steps S87 to S89 are repeated until the last frame of the content data is detected (S90). S9
0, the last frame of the content data is detected (in this case, all frames of the content data are normally received), the content management information of the content data (the content attribute information and the temporary data storage unit 22). The content table data buffer (which is a table of contents and records what content is stored from which position in the temporary data storage unit 22 to which position) is decoded. After that, it is written into the content table (FIG. 10) (S91). If the own identification ID is not included in the identification ID of the receivable portable terminal set in the content management information, the content data is stored in the content table data buffer and the content table. Is not written. After that, the processing after step S87 is repeated. By the above processing, the storage position of the content data for which reception by the mobile terminal is permitted and all frames are normally received is recorded in the content table data buffer, and the content table stores those data positions. The attribute information and the like of the content data are stored.

FIG. 10 is an example of a content table generated by the above processing. The first row of the content table shown in FIG. 10 is the user preference information stored in the preference information storage unit 27, and the others are the attribute information of each received content data and the start / end position in the temporary data storage unit 22. Information. The content storage module 26 calculates the distance between the attribute information of each content and the preference information of the user, and preferentially assigns the content data having the shorter distance to the data storage medium 2.
Save to 3. If the distances are the same, a predetermined rule may be followed. In the example of FIG. 10, the priority order of each content data is, for example, the order of contents 1, 3, 2, and 4. However, the content data already stored on the data storage medium 23 does not need to be stored again. In the information distribution system Z1, as described above, the content data is distributed according to the distribution schedule according to the preference information of the portable terminal 2 existing in the wireless communication area of the base station 1. Can meet user needs at a high level, but if there are multiple mobile terminals in the wireless communication area,
Naturally, the content data to be distributed includes data that does not suit the user's preference. However, by selectively storing only the content data that matches the user's preference information on the portable terminal 2 side as described above, the above-mentioned slight disadvantages on the distribution side can be completely solved. It is also very effective in terms of effective use of limited storage capacity.

(Specific Example of Charging Process) In charging for the distribution of content data, it is necessary to confirm that the content data has been normally distributed. This is because, even if the distribution side distributes the content data, if the content data is not normally received by the receiving side, it is not appropriate to perform charging. This is a particularly important problem in wireless information distribution where transmission errors are likely to occur. Of course, even for wireless information distribution, 1
In the case of one-to-one communication, there is no particular problem because it is possible to always check for transmission errors. However, in the information distribution system Z1 according to the present embodiment, since the content data is distributed from the base station 1 to each portable terminal 2 in a broadcast format as described above, the content data can be normally distributed normally. Cannot be confirmed at that time. Therefore, the information distribution system Z1 according to the present embodiment solves this problem by the following method. As described above, the mobile terminal 2
When the user enters the wireless communication area of a certain base station 1, the base station 1 is notified of the existence of the base station 1 and the distribution request data including the identification ID of the base station 1 is transmitted to the base station 1 in order to distribute the content data according to the user's preference. Send to 1. Therefore, by including in the distribution request data a reproduction result record composed of the ID of the content data normally received and reproduced in the past,
The base station 1 is made to recognize whether or not the previously transmitted content data has been normally received and reproduced.

The distribution request data transmitted from the portable terminal 2 to the base station 1 is configured as shown in FIG. 6, for example.
Upon receiving the distribution request data 1, the base station 1 transmits the reproduction result record contained therein to the charging information management server 3c. The charging information management server 3c checks the past distribution result of the content data and the above-mentioned reproduction result record, and performs a charging process for a match between them. FIG. 11 is an example of management information on the distribution content in the charging information management server 3c. In the management information, the distribution result of the content (content ID, ID of the distributed base station, distribution date and time) is recorded for each recognition ID, and the corresponding reproduction result record (content ID, this reproduction result record is received). The ID of the base station and the reception date and time of the playback result record) are recorded later. In the example of FIG. 11, the contents data JPOP111 and JPOP1 distributed to the portable terminal XYZ1 are displayed.
Among 23, the reproduction result was confirmed for JPOP123, but the reproduction result was not confirmed for JPOP111 (distribution error or not reproduced). Therefore, of these two content data, only the JPOP 123 is processed as a chargeable object. In addition, when a normal delivery content based on the preference information is received, a fixed fee is charged. When an additional fee is added to the delivery content based on the individual delivery request, the normal delivery / playback based on the playback result record is confirmed by the individual delivery request. May be performed only based on the distribution content. Further, in the above example, the accounting process is performed based on the playback result record indicating that the content data has been played back on the portable terminal side.
The charging process may be performed based on the reception record indicating that the reception has been performed normally. As described above, by transmitting the past reproduction result record or the like from the portable terminal 2 to the base station 1, the conventional broadcast format in which it is not possible to confirm whether the transmitted data is normally received on the receiving side or not. This eliminates the disadvantages of the information distribution described above and makes it possible to perform the accounting process correctly.

Next, a series of data distribution procedures in the information distribution system Z1 according to the present embodiment will be described with reference to the flowchart shown in FIG. Server 3
For example, the preference information of all registered users is set in the user information management server 3a via the Internet or the like. Also, individual distribution request information from a user who particularly desires distribution of specific content data is set as necessary (S30). Content data and its attribute information to be delivered to the mobile terminal 2 are stored and managed in the content server 3b of the server 3, and a part of them is transmitted to the base station 1 periodically, for example (S31). → S1
1). The content data transferred from the content server 3b to the base station 1 is selected in consideration of, for example, the distribution results of each base station. The content data and its attribute information transmitted from the content server 3b are stored in the base station 1
Is stored in the content data storage unit 12. When processing such as reproduction of content data is not performed, the transmission / reception unit 21 of the portable terminal 2 is in a radio wave standby state (S21). In this standby state, the base station 1
(Ie, when the mobile terminal 2 detects that the mobile terminal 2 has entered the wireless communication area of the base station 1),
The transmitting / receiving unit 21 transmits distribution request data (see FIG. 6) to the base station 1 (S22). When the base station 1 receives the distribution request data from the portable terminal 2 (S
12), the reproduction result record therein is stored in the charging information management server 3
c (S13). The charging information management server 3c, which has received the reproduction result record, compares the past distribution result of the content data with the above-mentioned reproduction result record, and performs the above-described charging processing for a match between them (S3).
2).

The base station 1 requests the user information management server 3a to transmit the preference information corresponding to the identification ID in the distribution request data (S14).
It is received from a (S33 → S14). Then, the distribution schedule generation unit 13 generates a distribution schedule of the content data based on the attribute information of each content data stored in the content data storage unit 12 and the user preference information (S15), and the distribution is performed. The transmission data (FIG. 4) including the content data and the management information of the content is generated according to the schedule (S16). Here, in addition to the attribute information of the content data, the content management information includes the identification ID of the mobile terminal for the content data transmitted to the specific mobile terminal by the individual distribution request, and the identification ID of the other content data. A special identification ID indicating that all mobile terminals can receive the message, for example, "XX000"
0 "is respectively stored. The generated transmission data is
The frame is divided into fixed-length frames, each of which is added with a header portion composed of frame information (the number of all frames) and an error detection code such as a CRC, and transmitted (S1).
7). Then, the distribution result (for example, the portable terminal ID of the distribution partner, the ID of the distributed content data, the distribution date and time, etc.) is stored in the charging information management server 3c as the distribution result storage, and is used for the charging process (S34). Upon receiving the transmission data, the mobile terminal 2 temporarily stores it in the temporary data storage unit 22 (S23). And
The content storage module 26 extracts each piece of content data from the transmission data sequentially stored in the temporary data storage unit 22, and sets the user preference information and the attribute information of each content data set in the preference information storage unit 27 in advance. The content data is stored in the data storage medium 23 in accordance with the priority determined based on the above (S24). At this time, if the own identification ID stored in the ID storage unit 25 is not included in the receivable portable terminal identification ID set in the content management information, the content data is stored. And is discarded. Then, when the user inputs a playback request,
The reproduction module 24 restores and reproduces the content data stored in the data storage medium 23 (S25). When the reproduction of the content data is completed, the reproduction module 24 writes the ID of the content data into the reproduction result record storage unit 28 as the reproduction result record (S26). The reproduction result record is incorporated into the distribution request data and transmitted to the base station 1 at the next transmission of the distribution request data (S22).

As described above, according to the information distribution system Z1 according to the present embodiment, by performing information distribution in a broadcast format using radio, a queue similar to the conventional one-to-one information distribution is established. It is possible to distribute a large amount of information to a plurality of users at the same time without being accompanied, recognize mobile terminals existing in the wireless communication area of the base station 1, and organize based on the preference information of those mobile terminals 2. Since the information is distributed in accordance with the distribution schedule that has been set, it is possible to perform information distribution that meets the needs of individual users, even though the information is distributed in a broadcast format. In addition, since wireless is used as a communication means, and the mobile terminal 2 detects that the mobile station 2 has entered the wireless communication area of the base station 1 and automatically receives information, the user has to perform a troublesome operation such as connection of equipment using a connector. No need to do. Further, the mobile terminal 2 determines the storage priority based on the preference information set in advance and the attribute information of the received content data, and stores the data within the storage capacity of the data storage medium 23 according to the priority. Therefore, content data that does not match the user's preference information can be excluded, and the limited storage capacity can be used effectively. Also, base station 1
In the management information of each piece of content data transmitted from, an identification ID of a mobile terminal that is permitted to receive the content data is stored, and in the mobile terminal 2, the management information of the received content data is stored. If the own identification ID is not stored in the receivable portable terminal's identification ID, the content data is discarded, so the content data distributed to a specific portable terminal based on the individual distribution request Can be prevented from being stored and played back on other portable terminals. That is, the same function as the one-to-one information distribution can be achieved at the same time while taking the form of the broadcast-type information distribution. Further, when the mobile terminal 2 enters the wireless communication area of the base station 1, the past playback result record and the like are transmitted from the mobile terminal 2 to the base station 1, so that the content transmitted from the base station 1 is transmitted. This eliminates the drawback of the conventional broadcast format information distribution in that it is not possible to confirm whether or not data has been normally received by the mobile terminal 2, and correct billing processing can be performed.

(Modification) In the above example, user preference information is registered in advance in the user information management server 3a,
When the base station 1 receives the identification ID from the portable terminal 2, the base station 1 is configured to take out the preference information corresponding to the identification ID from the user information management server 3a. It may be stored in the distribution request data and transmitted from the mobile terminal 2 to the base station 1 each time. Thereby, the communication load between the base station 1 and the server 3 can be reduced.
If the individual distribution request is set in advance using, for example, the Internet as described above, the content data can be automatically received the next time communication with the base station 1 becomes possible. There is, for example, base station 1
It is also possible to provide an input means for an individual distribution request in advance, and to transmit the content data when the user carrying the portable terminal 2 inputs the individual distribution request from this input means. Note that the preference information can also be registered from the input means of the base station 1. Also, when information is distributed only in one limited area, the function of the server 3 is integrated in one base station 1 instead of the configuration of a plurality of base stations 1 and one server 3. It is also possible to adopt a configuration in which the structure is changed. Also, in the above-described embodiment, the distributed contents include image contents such as still images and moving images, music contents, and characters such as news.
For example, audio content is used. Web content (HTML document) composed of characters and images is distributed, and the mobile terminal 2 is equipped with a WEB document display module such as a liquid crystal instead of the reproduction module 24. You may. Alternatively, a game or other application program (such as an applet of JAVA) may be distributed as content, and the portable terminal 2 may be equipped with a program execution module instead of the playback module 24. Thus, for example, the portable terminal 2 can be used as a personal portable information tool having the same function as a personal computer or a game machine.

[0032]

As described above, the present invention is an information distribution system for wirelessly distributing information from one base station to a plurality of portable terminals, wherein the portable terminal is a radio communication system of the base station. Upon detecting that the mobile station has entered the communication area, the base station transmits predetermined information to the base station.
Based on the predetermined information received from the mobile terminal, the mobile terminal that has entered the wireless communication area is recognized, and the recognized mobile terminal or its own owner's preference information is used in accordance with a distribution schedule. And an information distribution system for simultaneously transmitting information to each portable terminal in the wireless communication area. With such a configuration, it is possible to distribute information to a plurality of users simultaneously without involving a queue as in the conventional one-to-one information distribution by distributing information in a broadcast format using wireless communication. At the same time, in order to distribute information according to a distribution schedule organized based on preference information of mobile terminals existing in the wireless communication area of the base station, information distribution that meets the needs of individual users while being broadcast-type information distribution Can be performed. In addition, since wireless is used as a communication means, the mobile terminal automatically detects information when it enters the wireless communication area of the base station and automatically receives information. There is no need to perform cumbersome operations such as connection.

As a mechanism for obtaining preference information on a mobile terminal that has entered the wireless communication area of the base station on the base station side, for example, the predetermined information transmitted by the mobile terminal includes the mobile terminal or its owner. If the preference information for each portable terminal or each owner thereof is registered in advance in the base station or in a server capable of communicating with the base station, the base station or the server Can obtain preference information about the mobile terminal based on the identification information received from the mobile terminal.
At this time, the registration of the preference information is performed by, for example, the portable terminal,
This can be performed via the Internet, a public line, or the like. Another mechanism for the base station to obtain preference information about the mobile terminal that has entered the wireless communication area of the base station is that the predetermined information transmitted by the mobile terminal includes the mobile terminal or the owner of the mobile terminal. It is also conceivable to include preference information. This makes it possible to reduce the processing load when searching for preference information on the base station side and the communication load when transmitting preference information in the server to the base station.

Further, the base station transmits specific information with the identification information of the specific mobile terminal added thereto based on a request from the specific mobile terminal or its owner, and the mobile terminal transmits its own information. If the specific information can be reproduced only when the own identification information and the identification information added to the specific information match, the specific information distributed to the specific mobile terminal can be It can be prevented from being reproduced on other portable terminals. As a result, the same function as one-to-one information distribution can be achieved at the same time while taking the form of broadcast-type information distribution. At this time, if the identification information added to the specific information does not match the identification information of the portable terminal, the portable terminal may be configured to discard the received specific information, for example. Here, the request for the specific information can be input in advance via the Internet or a public line, and the base station transmits the request for the specific information to the mobile terminal in a state where the request for the specific information is input. If the specific information is transmitted when the user enters the communication area, the user sets a request for the specific information in advance so that the user enters the wireless communication area of the base station next. Sometimes, the information can be automatically obtained without any operation, which is convenient. Further, the base station is provided with input means for inputting the request for the specific information, and the base station transmits the specific information when the request for the specific information is input from the input means. Alternatively, the request for the specific information can be input via the mobile terminal, and the base station transmits the specific information when the request for the specific information is input via the mobile terminal. If a user inputs desired information from a base station or a mobile terminal, the user can immediately receive the desired information at that time,
The same function as the information distribution using the conventional vending machine can be realized. However, since information is received wirelessly, it is not necessary to perform cumbersome operations such as connecting devices with a connector as in the related art.

[0035] The accounting information for each mobile terminal is generated based on the predetermined information received from the mobile terminal by the base station and a transmission result of information transmitted corresponding to the predetermined information. However, in order to perform accurate billing, it is necessary to confirm that the transmitted information is normally received by the portable terminal. As a method of this confirmation, the predetermined information transmitted by the mobile terminal includes:
It is possible to include a record of reception of information normally received in the past or a record of reproduction of such information, and charge based on the record of reception or the record of reproduction received by the base station. Conceivable. As a result, it is possible to solve the drawback of the conventional broadcast format information distribution in which it is impossible to confirm whether the information transmitted from the base station has been normally received by the portable terminal side, and to perform the accounting process correctly. Further, the portable terminal sets the priority of storing the information received from the base station in the memory, for example, as the distance between them becomes smaller, based on the preset preference information and the attribute information of the information. With this setting, it is possible to automatically exclude information that does not match the user's preference information, thereby improving the convenience of the user in reproducing the information and effectively using the limited storage capacity. It is possible.
