Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data distribution system for mobile terminals, which distributes data such as movies and dramas according to the position of the receiver.

[0002]

2. Description of the Related Art For example, in television broadcasting and radio broadcasting, advertisements (hereinafter referred to as "C
(Also referred to as “M”), the advertising revenue from the sponsor is obtained and used for operating funds. In traditional broadcasting,
The key stations that form the core of the broadcasting network supply local programs in each region with programs and commercials throughout the country. In addition, local stations in each region have their own programs and local C
M may be broadcast only in that area.

By the way, in recent years, with the progress of mobile communication technology, Internet technology and the like, so-called mobile computing, which is mainly used in mobile phones and personal digital assistants, has become widespread. By using mobile computing, a user can connect to a network and enjoy various types of data such as moving images, still images, characters, and music even while moving.

For example, Japanese Patent Laid-Open No. 2000-222331 discloses a technique for dynamically changing the advertisement content transmitted from the web server to the user's terminal in consideration of the user's current position and time. According to this, it becomes possible to provide the user with a CM according to the current position and time of the user.

[0005]

In the prior art, the contents of the CM can be changed according to the current position and time of the user, but the contents of the CM cannot be changed in consideration of the future position of the user. , It is impossible to deliver an appropriate CM according to the moving route of the user.

In recent years, short-distance wireless LAN (Local A
Data distribution service using rea Network) is also under consideration. Short-distance wireless communication has a narrow service area compared to conventional television broadcasting and radio broadcasting,
The user may go out of the service area even if the user moves a little. Therefore, even if the user moves a short distance, it is not possible to perform data distribution according to the current position of the user.

The present invention has been made in view of the above-mentioned various problems, and an object thereof is a mobile phone capable of distributing data having appropriate contents based on the current position or future position information of the mobile terminal. It is to provide a data distribution system for terminals. Another object of the present invention is to provide a data distribution system for mobile terminals, which allows a user to distribute data assigned to a predetermined point in advance before the user reaches the predetermined point.

[0008]

In order to solve the above-mentioned problems, a mobile terminal data distribution system according to the present invention includes a storage means for storing main data and sub-data constituting distribution data, and a mobile terminal. Selection means for selecting distribution data to be distributed, and setting based on current or future position information of the mobile terminal can be set to reproduce predetermined sub-data at a predetermined position of the selected distribution data. The sub-data setting means and the delivery means for delivering the selected delivery data to the mobile terminal are provided.

Here, the main data means the data that forms the core of the distribution data, and specifically, for example, a movie,
Data of various programs such as dramas, sports, entertainment, music, and education can be cited. The sub-data is provided between the main data distributions or before or after the main data distribution, and specifically, advertisement (CM) data can be mentioned. Various methods can be adopted as the method of generating the distribution data. One method is to separately manage the main data and the sub data, and select the main data and the sub data when generating the distribution data. Another method is to manage the main data and the sub data in advance in association with each other, and select the sub data and adjust the reproduction position before distribution. As a mobile terminal,
For example, a mobile phone, a mobile information terminal, a portable personal computer, etc. can be mentioned. Further, in this system, the storage means, the selection means, the sub-data setting means, and the distribution means do not have to be realized in one computer, and each means is realized in each node, so that a bidirectional communication network can be used. It can also be configured by being interconnected and working together.

When the user (recipient) selects the distribution data, the reproduction position of the predetermined sub data in the distribution data is set based on the current or future position information of the portable terminal. In this way, after the reproduction position of the sub data is set, the distribution data is distributed to the mobile terminal.

According to one aspect of the present invention, as the sub-data, first sub-data having a low dependency on the position information of the mobile terminal and the sub-data having a lower dependency on the position information of the mobile terminal than the first sub-data. Two types of sub data, that is, the high second sub data, are prepared in advance.

[0012] The first sub-data is data provided in a relatively wide area, such as CM data common throughout the country,
The second sub data is data provided only in a specific area and a specific place.

In another aspect of the present invention, all or part of the first sub-data included in the distribution data is selected according to selection by the distributor of the distribution data or the receiver of the portable terminal. The first sub-data can be replaced with the second sub-data.

When the main data and the first sub-data are associated with each other in advance, all or part of the first sub-data in the distribution data is selected by the distributor or the receiver.
It can be replaced with the second sub-data.

In another aspect of the present invention, the second sub-data is distributed before the mobile terminal reaches the position associated with the second sub-data.

The second sub-data is data having a high geographical dependence provided in a specific area or a specific place. Thus, the value of the second sub-data is halved after the recipient has passed by that particular area or place. In addition, even if the second sub-data is distributed when the particular area or place is reached, the content transmitted by the second sub-data may not be fully utilized due to lack of preparation or the like. Therefore, before the recipient reaches a specific area or place, the second sub data associated with the area or the like is distributed in advance.

According to another aspect of the present invention, the distribution means acquires in advance information of the starting point and the destination of the portable terminal, and allocates the information to the respective feasible points on the route connecting the starting point and the destination. The second sub data that is present is concentrated and distributed before the mobile terminal reaches each feasible point.

The recipient informs the delivery means of the place of departure and the destination before departure. Regarding the place of departure,
The recipient does not need to notify by manual input. This is because it is possible to automatically notify the distribution means by using the position of the nearest mobile communication base station with which the mobile terminal can communicate or the position information system (GPS) built in the mobile terminal. In addition to the starting point and the destination, intermediate points (via points) and transportation means (for example, car,
Trains, planes, walking, etc.) may also be notified.
The distribution unit estimates the travel route from the information of the departure place and the transit place, and detects the second sub data distributed on the route. Specifically, the possible transit points located on the route connecting the departure point and the destination (which is called the "possible" point because the recipient does not always stop there) are calculated.
The second sub-data previously associated with each feasible point is detected. Then, the second sub-data is distributed in a concentrated manner before the departure of the recipient, immediately after the departure, or before the first reachable point is reached. As a result, the recipient can concentrate and view the information on the route that he / she is going to travel in advance, and reflect it on the action schedule.

According to one aspect of the present invention, there is further provided a wireless communication base station for performing two-way data communication with a mobile terminal via short-range wireless communication. Then, when the mobile terminal is located in one of the communication areas of each wireless communication base station, the sub data associated with the wireless communication base station is distributed to the mobile terminal via the wireless communication base station. To configure.

For example, a short-distance wireless communication base station capable of data communication in a short distance having a radius of several tens to several hundreds of meters is arranged in advance in a specific area or place. For example, wireless communication base stations are arranged in hotels, airport lobbies, train stations, amusement parks, stores, department stores, and the like. When the mobile terminal of the recipient enters the communication area of the wireless communication base station, the sub data associated with the specific area or place is delivered to the mobile terminal. This makes it possible to provide more familiar and useful information such as limited-time souvenir information and attraction schedules.

According to another aspect of the present invention, there is further provided a wireless communication base station for performing two-way data communication with the mobile terminal via short-distance wireless communication, and each wireless communication station is provided with each wireless communication base station. It has the 2nd memory | storage means which beforehand memorize | stores the 2nd subdata matched with the communication base station. Then, when the mobile terminal is located in any one of the communication areas of the wireless communication base stations, the second sub-data associated with the wireless communication base station is transferred via the wireless communication base station. Deliver to the terminal.

Here, as one method of storing the second sub-data in the second storage means, the second sub-data is downloaded from the delivery means via the communication network regularly or irregularly. There is something to do. As another method, there is a method of installing the second sub data recorded on a recording medium such as a DVD-ROM in the second storage means. Alternatively, both can be used together.

In another aspect of the present invention, the mobile terminal is configured to communicate with the distribution means via another wireless communication different from short-range wireless communication, and the mobile terminal communicates with each wireless communication base station. When it is outside the area, the sub data is distributed from the distribution means to the mobile terminal.

As other wireless communication, mobile communication provided by a mobile communication carrier (carrier) (a mobile phone or PHS) is used.
Services, etc.). When the mobile terminal goes out of the communication area of the wireless communication base station, the sub data is directly distributed from the distribution means to the mobile phone through another wireless communication without using the wireless communication base station.

According to another aspect of the present invention, the distribution means comprises:
By estimating the position of the mobile terminal outside the communication area, sub data corresponding to the position information of the mobile terminal is distributed.

For example, when the destination has been notified to the delivery means in advance, the route connecting the last communicating radio communication base station and the destination is calculated, and the moving distance is calculated from the elapsed time and the average moving speed. Thus, the approximate position can be estimated. The position can also be estimated by specifying a base station of mobile communication with which communication is possible.

In another aspect of the present invention, the portable terminal further comprises direction detecting means for detecting the moving direction of the own device, and the distributing means has the moving direction of the portable terminal detected by the direction detecting means. The sub data is delivered to the mobile terminal according to the.

Examples of the direction detecting means include a gyro sensor and a geomagnetic sensor. As a result, it becomes possible to deliver not only the position of the mobile terminal but also the sub data according to the moving direction thereof.

In another aspect of the present invention, the charging condition for the receiver of the mobile terminal differs depending on the degree to which the sub data is distributed to the mobile terminal. Then, before the distribution data is distributed to the mobile terminal, the estimated amount of money calculated according to the charging condition is presented to the receiver of the mobile terminal.

Based on the degree of viewing of the sub-data (viewing count, amount of data, viewing time, etc.), it is possible to reduce the fee charged to the recipient according to the viewing of the sub-data. The reduced amount can be included in the bill for the sub data provider. By presenting the predicted amount of money to the receiver before the distribution of the distribution data, the usability is improved and the receiver's sense of security is increased.

The present invention can also be understood as a method or a computer program. The program can be distributed via a communication network or recorded in a recording medium and distributed. As the recording medium, various media such as a CD-ROM, a DVD-ROM, a hard disk, and a memory can be used.

FIG. 1 is an explanatory diagram schematically showing the overall configuration of a mobile terminal data distribution system.

The content distribution station 10 transfers the content data consisting of program data and CM data to the portable terminal 50.
It is distributed according to the current position or the future position of.
The content distribution station 10 is connected to the data distribution server 20 and the billing server 30 so that they can communicate with each other. The data distribution server 20 stores program data and CM data, and transmits the data in response to a request from the content distribution station 10. The program data and the CM data may be managed by different data distribution servers. The billing server 30 receives the result of distribution from the content distribution station 10 to the mobile terminal 50, and calculates the amount charged to the receiver or the CM data provider (sponsor).

The content distribution station 10 is connected to each local base station 40 that provides a short-distance wireless LAN service via a communication network CN such as the Internet so that two-way communication is possible. Each local base station 40 is installed in, for example, an airport or a hotel lobby, a waiting room at a station, various stores such as department stores and restaurants, and the like.

When the receiver carrying the portable terminal 50 moves from the place of departure to the place of destination by foot, car or train, the local base station 4 located on the moving route.
Pass through the 0 communication area. The communication area of each local base station 40 is shown by a virtual line polygon in the figure. When the mobile terminal 50 enters the communication area, local CM data is transmitted from the local base station 40 to the mobile terminal 50. Here, the local CM data is CM data specific to a place (area) where each local base station 40 is installed. For example, information on sales of local specialty products, information on nearby tourist spots, and the like.

The portable terminal 50 can also perform mobile communication via the mobile communication station 60, in addition to the short-range wireless communication with the local base station 40. Content distribution station 1
0 is also connected to the mobile communication station 60 so as to be able to perform two-way communication, and data can be distributed from the content distribution station 10 to the mobile terminal 50 via the mobile communication wireless base station 61. .

Various methods can be adopted as a data distribution method from the content distribution station 10 to the portable terminal 50. One method is to distribute all program data, default CM data, and local CM data to the mobile terminal 50 via the local base station 40. The other is to distribute the program data and the default CM data to the mobile terminal 50 via mobile communication, and the local CM data specific to the area from the local base station 40 to the mobile terminal 50 via the short-distance wireless LAN. It is a method of distribution. Also, both of them can be used together. Further, a large-capacity storage device is installed in the mobile terminal 50, and program data, default CM data, and local CM data at a scheduled transit point are stored in advance in the large-capacity storage device of the mobile terminal 50. There is also a method of reproducing the local CM data when 50 actually reaches the communication area of the local base station 40 (or before the arrival).

FIG. 2 is an explanatory diagram showing the configurations of the content distribution station 10, the local base station 40 and the portable terminal 50.

The content distribution station 10 includes a program management section 1
1, a CM management unit 12, a distribution condition setting unit 13, and a content distribution unit 14. The program management unit 11 and the CM management unit 12 manage the program data and the CM data, respectively. When a desired program is designated by the receiver, the program management unit 11 refers to the program management table and the program database, and refers to the designated program as the data distribution server 2
Notify 0. The CM management unit 12 uses a CM database or the like to manage both default CM data and local CM data.

Here, the default CM data is wide area CM data provided over a relatively wide area, and is associated with program data in advance.
It should be noted that although the present embodiment is described as being associated with program data in advance, the present invention is not limited to this. The two can be associated with each other when the content data is distributed, or different default CM data can be associated with each mobile terminal even for the same program data. On the other hand, the local CM data, as described above, is a C that has a strong locality that depends on a specific area or place.
It is M data and can also be called narrow area CM data or area-specific CM data.

The distribution condition setting unit 13 sets and manages distribution conditions of content data for each recipient. The distribution conditions mean various conditions when distributing the content data. For example, whether or not to watch a CM, whether to desire a local CM when watching a CM, a plurality of CMs are concentrated. It is possible to cite whether or not to view the contents in a distributed manner or to view them in a distributed manner. Depending on the delivery conditions
The billing to the recipient can be set differently. For example, C
A high fee is charged to a recipient who does not view M at all, and a low fee is charged to a recipient who views the default CM.

The content distribution unit 14 distributes the selected content data to each portable terminal 50 according to the distribution condition of each recipient. When the distribution of the content data is completed, the content distribution unit 14 charges the information for identifying the recipient and the information about the distribution of the content data (the program name, the type of CM viewed, the viewing time, the viewing time, etc.) Notify the server 30.

The local base station 40 comprises a communication unit 41, a buffer 42, a broadcast control unit 43, a local CM data storage unit 44 and a transmission unit 45. The communication unit 41 is connected to the content distribution station 10 via the communication network CN so as to be able to perform two-way communication, and the content data transmitted from the content distribution station 10 is stored in the buffer 4 via the communication unit 41.
Temporarily stored in 2.

The broadcast controller 43 controls the distribution of content data within the communication area of the local base station 40. The broadcast control unit 43 is used by the content distribution station 1
The data stream (program data, default CM data) received from 0 is distributed by the wireless LAN via the transmitter 45. As will be described later, this data stream, that is, the CM control information in the content data is the local CM.
When the reproduction of data is permitted, the broadcast control unit 43
The local CM data is read from the local CM data storage unit 44, and the read local CM data is transmitted from the transmission unit 45 instead of the default CM data or together with the default CM data.

The portable terminal 50 includes a communication section 51 and a display section 5.
2, an operation unit 53, a storage unit 54, and a control unit 55 are provided, and the control unit 55 controls each unit. The communication unit 51 can perform bidirectional communication with the local base station 40 by short-range wireless communication, and can also perform bidirectional communication via the base station 61 for mobile communication.

The display unit 52 is, for example, a liquid crystal display or the like, and the distributed content data is displayed by the display unit 52. It should be noted that the reproduction circuit for voice and the like is of course the mobile terminal
Although 0 is provided, illustration is omitted. The operation unit 53 includes a plurality of operation buttons and the like, and selection of programs and distribution conditions is performed via the operation unit 53. The storage unit 54 is for temporarily storing the received content data.

When the storage area of the storage unit 54 is sufficiently large,
It is also possible to store all or part of the content data in the storage unit 54. In addition, the authentication data necessary for receiving the distribution of the content data from the content distribution station 10 is also stored in the storage unit 54. The storage unit 5
4 can also be configured from a plurality of storage devices such as a built-in memory, a built-in mass storage device (HDD, etc.), an externally attachable / detachable IC card, and the like. All or part of the program data or CM data is stored in advance in a removable IC card, memory card, etc., and when the receiver reaches a predetermined position, the data recorded in the card It can also be configured to allow playback.

FIG. 3 is an explanatory diagram showing the data structure of the content data. FIG. 3A shows the content distribution station 1.
Outline of data stream sent from 0, Fig. 3
(B) shows an outline of a data stream transmitted by the local base station 40 within the communication area of the local station.

As shown in FIG. 3A, the content data transmitted by the content distribution station 10 is the program data P.
D, CM control information CD and default CM data DCM
It consists of That is, the program is C for each section.
M reproducible areas are set, and CM control information is provided in each CM settable area. The CM control information describes various control information for CM reproduction, and includes, for example, flag information indicating the presence / absence of CM, the CM broadcast time, and the possibility of replacement with local CM data.

Depending on the flag information, refusal to replace the default CM data with the local CM data (for example, "0
0 ”), replacement permission (eg“ 01 ”), default CM
It can represent that no data is stored (for example, “11”).
Default CM data is stored in advance in each section of the program, that is, in a section where a CM can be inserted. However, the default CM data is not always stored in all the sections. Further, there may be a case where no default CM data is stored.

When the control flag in the CM control information permits replacement of the default CM data with the local CM data, as shown in FIG. 3B, the replacement-permitted default CM data is: It is replaced with predetermined local CM data in each local base station 40. In FIG. 3, the default CM data DCM2 is replaced with the local CM data LCM1 and the default CM data DCM4 is replaced with the local CM data LCM3, respectively, and the program is broadcast. In the section in which the default CM data is not stored from the beginning, the local CM data LCM2 is inserted and reproduced.

Next, FIG. 4 is an operation explanatory diagram showing the flow of the entire distribution system.

First, the receiver desiring to deliver the program issues a delivery request for the desired content to the content delivery station 10 via the portable terminal 50 (S1). Where, for example,
When the content distribution service is limited to pre-registered members, predetermined authentication information such as user name and password is transmitted, but this is omitted because it is not the gist of the present invention. Now, the content distribution station 1 that received the distribution request
0 transmits the delivery condition to the portable terminal 50 and presents it to the recipient (S2). The recipient selects a desired condition from the presented distribution conditions (for example, whether or not to watch the CM, and desires to watch the local CM, etc.).

The receiver can also notify the travel route in advance (S3). For notification of travel route,
For example, the place of departure, the destination, the waypoint, the means of transportation, the date and time of departure, the date and time of arrival, and the like can be included. The content distribution station 10 calculates an approximate charge based on the distribution conditions and the like, and transmits the approximate amount of money to the portable terminal 50 to request confirmation of the recipient (S4). For example, the content distribution station 10 can present an approximate amount of money by subtracting the amount of money corresponding to CM viewing from the basic charge of viewing a program. Here, the estimated amount of money is because there is no guarantee that the receiver will view the local CM data through the communication area of the local base station 40. At this point, a cost estimate is calculated and presented based on the recipient's self-report.

The receiver can select the local CM data (S5). The recipient is asked to confirm the selected result (S6). For example, the receiver may refuse to view all local CMs, or may desire to watch local CMs only at a predetermined local base station 40. Alternatively, it is possible to request the viewing of the local CM only for a desired genre (for example, health, travel, landmarks, etc.)

The content distribution station 10 stores information (for example, an IP address) for identifying the recipient with respect to all the local base stations 40 under management or the local base station 40 located on the moving path of the recipient. The receiver notifies the desired CM (S7). Upon receiving the notification content, the local base station 40 returns a confirmation notification to the content distribution station 10 (S8).

Then, the content (program) is distributed from the content distribution station 10 to the portable terminal 50 of the recipient (S9). Also, the default C set to not replaceable
When the delivery time of M data is reached, default CM data is also delivered (S10). The receiver is the local base station 40.
When entering the communication area of, the local base station 40 delivers predetermined local CM data to the portable terminal 50 instead of the default CM data (S11).

When the local base station 40 finishes distributing the local CM data, the local base station 40 reports to the content distributing station 40 which local CM data has been distributed to which recipient (S12). In the content distribution station 40, the local C
The local base station 40 is notified of the price of the service of giving the delivery opportunity of M (S13).

Now, here, when the receiver stays in the communication area of one local base station 40 for a long time, and the receiver only wants a local CM from the local base station 40 (for example, an airplane). If you are staying in the airport lobby waiting for the transfer time etc.), the default CM
Data can be easily replaced with local CM data. On the other hand, when the receiver walks through the communication areas of the plurality of local base stations 40, the timing with the CM broadcast time may not be obtained. In such a case, as will be described later, even if it is outside the communication area of the local base station 40,
It suffices to take measures such as specifying the position of the recipient and delivering the local CM data, or delivering the CM data collectively before and after the program.

When the distribution of the content is completed (S14), the content distribution station 10 calculates the final billing charge based on the number of CMs distributed to the recipient and notifies the recipient (S15). ).

Next, FIG. 5 is a flowchart showing an outline of CM data setting processing in the content distribution station 10.

First, the content distribution station 10 obtains information about distribution conditions, moving routes, etc. from the portable terminal 50 (S21). Next, it is determined whether or not the recipient desires to view the local CM (S22). If the recipient desires to view the local CM, the control flag in the predetermined CM control information is set to "permission for replacement". It is set (S23). For example, regarding the default CM data that is set with a low distribution priority in consideration of the intention of the sponsor, etc.
Can be replaced with data. And local C
Local base station 40 scheduled to deliver M data
Is notified in advance that the local CM data will be distributed (S24).

Next, it is determined whether or not the receiver desires concentrated viewing of CM (S25). Depending on the selection of the receiver or the distributor (sponsor, etc.), all or part of the CM data can be collectively viewed at a predetermined position of the content data. The receiver may, for example, before or after the start of the program, or at a predetermined time such as in the middle of the program,
All local CM data can be viewed in advance. When the receiver desires the intensive viewing or the distributor instructs the intensive viewing, the configuration of the content data is set so that the predetermined CM data is collectively delivered in a predetermined time zone ( S26).

The present embodiment is configured as described above.
FIG. 6 shows how the data distributed to the mobile terminal 50 is reproduced.

As shown in FIG. 6A, when the recipient moves from the place of departure to the destination, the portable terminal 50 of the recipient.
Is a local base station 4 installed at transit points P1 and P2
Pass through the 0 communication area. When the mobile terminal 50 enters the communication area of each local base station 40, each local base station 4
From 0, local CM data peculiar to each of the transit points P1 and P2 are distributed to the mobile terminal 50 and distributed.

Further, as indicated by reference numeral LCMP2 in FIG. 6A, the portable terminal 5 is placed in the communication area of the waypoint P2.
It should be noted that the local CM data LCMP2 associated with the transit point P2 can be distributed from the content distribution station 10 to the mobile terminal 50 via the mobile communication station 60 before the entry of 0. . In the present embodiment, the communication path for distributing program data and CM data is automatically switched according to the position of the mobile terminal 50. That is, the mobile terminal 50 is the local base station 40.
Content distribution station 1 when located in the communication area of
Data is distributed from 0 via the local base station 40, and when the portable terminal 50 is outside the communication area of the local base station 40, the content distribution station 10 distributes the data via the mobile communication station 60.

As shown in FIG. 6B, before the receiver reaches the transit points P1 and P2, all the local CM data of the scheduled transit points are transferred from the content distribution station 10 to the portable terminal 5.
It is also possible to pre-deliver to 0 and play. This allows the recipient to obtain in advance necessary or useful information before reaching the waypoint.

According to the present embodiment, the CM data can be distributed based on the current or future position information of the recipient, so that the CM data can be distributed more appropriately. In particular, since the local CM can be viewed before the recipient reaches the place where the local base station is installed, it is possible to contribute to the action plan formulation of the recipient.

Since the communication path (distribution path) for distributing data is automatically switched according to the position of the recipient (position of the portable terminal 50), appropriate data distribution is performed according to position information. be able to.

Furthermore, since the CM data can be viewed in a concentrated manner, the recipient is distributed geographically on the moving route at a relatively early time, such as before the movement starts or immediately after the movement starts, and thus has a high geographical dependency. Information can be obtained. Therefore, the acquired information can be reflected in the future action plan, and the waiting time while moving can be effectively used.

2. Second Embodiment FIG. 7 is a flowchart showing an outline of CM setting processing according to the second embodiment of the present invention. The feature of this embodiment is that the recipient sets the distribution of the local CM data based on the movement plan notified to the content distribution station 10 in advance.

That is, when the content distribution station 10 receives a notice of a movement plan (departure point, destination, movement start date and time, estimated arrival date and time, transportation means, etc.) from the recipient, it refers to a map server (not shown). Then, the moving route of the receiver is predicted, and the local base station 40 located at the waypoint on the predicted moving route is detected. The content distribution station 10
For example, "* month * day, we assume that we will arrive at destination Y from departure point X via station A and station B (transfer station),
We will send you regional information. A confirmation message such as “” is transmitted to the mobile terminal 50 and the recipient is asked to confirm (S3
1).

When the recipient confirms (S32), a predetermined C
The control flag in the M control information is set so as to allow the replacement with the local CM data (S23), and the local base station 40 predicted to pass the receiver is notified in advance of the distribution of the local CM data. (S33).

3. Third Embodiment Next, FIG. 8 is an explanatory diagram showing the overall operation of a data distribution system according to a third embodiment of the present invention. The feature of the present embodiment is that even when the mobile terminal 50 is located within the communication area of the local base station 40, the local CM data can be directly carried from the content distribution station 10 without going through the local base station 40. The point is to deliver to the terminal 50. When the mobile terminal 50 of the recipient reaches the communication area of the local base station 40, the local base station 40 notifies the content distribution station 10 that the mobile terminal 50 has entered the communication area (S41). As a result, the content distribution station 1
0 delivers predetermined local CM data to the portable terminal 50 via the mobile communication station 60 (S42).
