Description

  The present invention relates to a mobile communication system that provides content. In particular, the present invention relates to a mobile communication system, a method, a program, a mobile communication terminal, and a server that perform management and protection for maintaining the rarity of content with respect to content distribution and maintaining the attractiveness of the content.

In recent years, a ubiquitous network that enables creation of an environment where each communication device can receive content with an overwhelming amount of information anytime and anywhere has become widespread.
According to such a ubiquitous network, contents such as music, video, games, etc., as well as contents delivered by electronic commerce, so-called “rich contents” can be obtained forever.

In addition, by removing the restriction on the amount of information that can be transmitted by each communication device by the ubiquitous network, an environment in which each communication device continuously transmits some information in various places is prepared.
However, on the contrary, there is a problem that there is an industry in which conventional business cannot be performed on the ubiquitous network. For example, stores that have been based on face-to-face sales such as souvenir shops in tourist areas have increased the ability to attract customers and handle business methods that increase sales through sales capabilities.

In these industries, we would like to avoid increasing the number of product options only for customers on the ubiquitous network.
Therefore, in order to attract customers, the provision of attractive content that can be received only at the store is considered using communication means whose reception range is short-distance.
Examples of the communication means include infrared communication, Bluetooth, and wireless LAN (Local Area Network) (IEEE (Institut of Electrical and Electronics Engineers) 802.11b).

If this is realized, the ability to attract customers will increase in order to receive attractive content. However, there are the following problems.
In conventional mobile communication terminals, once received data can be transmitted to other mobile communication terminals wherever they are located, so content is distributed indefinitely, content scarcity is reduced, This means that the content is less attractive in terms of content scarcity management and protection.

In addition, in the conventional content management and protection, copy prohibition, the number of copies, etc. can be controlled, but if content distribution is completely restricted, it means that the ability to attract customers is reduced.
There are the following conventional techniques related to such problems.
Conventionally, terminal number information is transferred from a terminal to a content server in order to obtain a content distribution system and its terminal device that can protect the interests of industry parties such as copyright holders, distributors, and sales by preventing unauthorized copying of the content. It is sent via the wireless network, the content server encrypts it with this terminal number information and transmits it via the wireless network, and the terminal decrypts this encrypted content data with the terminal number information, so that other terminals Some copy protection is provided to protect the interests of industry parties such as copyright holders, distribution companies, and sales (see, for example, Patent Document 1).

However, the conventional technique described in Patent Document 1 prevents unauthorized copying of content from a content server, but does not maintain the rarity of content with respect to the distribution of content and maintain the attractiveness of content.
In addition, in the past, computers have been used to provide real-time broadcasting that satisfies the purpose of people who gather in a limited area with a specific purpose, and to implement sales promotion methods that can be linked to the broadcast. By selectively providing a transmitting (light emitting) device corresponding to the reception (light receiving) logic of the communication device possessed by the mobile device that can be used legally within a limited range, and a management server via the Internet, the web site or Real-time broadcasting at each limited place prepared on the mobile web site is provided to the mobile, and further, real-time sales promotion information such as price changes and real-time CM information is transmitted to the management server. Some sales promotion information is reliably provided in real time to customers near the computer (for example, Patent Document 2). Irradiation).

However, the conventional technology described in Patent Document 2 provides various types of sales promotion information to the customer. As described above, the rarity of the content is maintained with respect to the distribution of the content, and the attractiveness of the content is maintained. Not.
Conventionally, in order to provide a data transmission suppression apparatus suitable for effectively preventing the unlimited transmission of data to other computers and protecting the creator's interests, transmission permission is provided in the transmitting computer. The number of times data is associated with the transmission target data, the transmission target data is transmitted, and the transmission side data is transmitted based on the associated transmission permission number data in response to an attempt to retransmit the received transmission target data. In some cases, the number of permitted transmissions is updated in a direction in which the number of permitted times decreases, and retransmission of data to be transmitted is prohibited when there is no permitted number of times of transmission (see, for example, Patent Document 3).
However, in the conventional technique described in Patent Document 3, the transmission permission count data is updated in a direction in which the transmission permission count decreases, and when there is no transmission permission count, retransmission of the transmission target data is prohibited. In addition, it does not maintain the rarity of the content with respect to the distribution of the content and maintain the attractiveness of the content.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a network of a mobile communication system according to the present invention. As shown in the figure, in the mobile communication system, the mobile communication terminal 101 and the mobile communication terminal 104 can transmit and receive wirelessly via the mobile communication network 103, and the content server 105 can perform mobile communication. The content is provided to the terminal 101 and the mobile communication terminal 104, and the transmission permission device 102 is located at a specific location, accessed from a short range, and only the mobile communication terminal 101 that has acquired the content has another mobile unit. A system configured to allow the communication terminal 104 to transmit content, and operates under program control.

Here, the mobile communication terminal 101 and the other mobile communication terminals 104 are not limited to the mobile communication network 103, but also include known methods including infrared communication, Bluetooth, and wireless LAN (Local Area Network) (IEEE802.11b)). It is also possible to send and receive via
The content server 105 is realized by a personal computer, a workstation, or the like, and includes a content storage device such as a hard disk drive (HDD), a wireless device, an antenna that performs wireless transmission / reception, control software, and the like. When there is a transmission request from the communication terminal 101, the content incorporated in the mobile communication terminal 101 is transmitted.

Further, the antenna configured in the content server 105 does not need to be physically integrated with the content server 105, and the antenna may be an antenna (wireless access point) of a base station of the mobile communication network 103. What is necessary is just to perform by the known method in which the communication terminal 101 can receive a content.
The transmission permission apparatus 102 is present at a specific location, and gives content transmission permission information to the mobile communication terminal 101 existing within a short distance range from the position of the transmission permission apparatus 102.

For example, the transmission permission apparatus 102 is a transmitter, which includes an antenna that performs transmission and a control unit, and transmits the transmission permission information of the content of the content server 105 using a medium having a short reach. Yes, when there is a transmission request from the mobile communication terminal 101, transmission permission information is transmitted to the mobile communication terminal 101.
In this case, the transmission permission information is information that determines whether or not content transmission is possible depending on the distance between the transmission permission device 102 and the mobile communication terminal 101. That is, content transmission is restricted from being transmitted from the mobile communication terminal 101 to another mobile communication terminal 104 when the mobile communication terminal 101 is outside the short-range range of the transmission permission device 102. .

In order to realize the mobile communication terminal 101 and the transmission permission apparatus 102 at low cost, it is not necessary to perform a special protocol sequence. For example, the transmission permission apparatus 102 simply transmits a permission signal at a specific frequency as transmission permission information. You can just send it out.
Furthermore, examples of the medium having a short reach range include infrared communication, Bluetooth, and wireless LAN (IEEE802.11b).

  Although the mobile communication terminal 101 and the mobile communication terminal 104 can access the content server 105 and receive content from the content server 105, the mobile communication terminal 101 transmits the content acquired from the content server 105 to mobile communication. In order to transmit to the terminal 104, the transmission permission apparatus 102 must be accessed to acquire the transmission permission information. Conversely, the mobile communication terminal 104 transmits the content acquired from the content server 105 to the mobile communication terminal 101. In this case, it is necessary to access the transmission permission apparatus 102 and acquire the transmission permission information.

As described above in detail, the content server 105, mobile communication network 103, infrared communication, Bluetooth, and wireless LAN (IEEE802.11b) in FIG. 1 are well known to those skilled in the art, and the features of the present invention are as follows. Since they are not directly related to each other, their detailed description is omitted.
Detailed description will be given below.

FIG. 2 is a block diagram showing a schematic configuration of the mobile communication terminal 101 in FIG. As shown in the figure, the mobile communication terminal 101 includes an antenna 131, a transmission / reception unit 132, an encoding / decoding unit 133, a storage unit 134, an input / output unit 135, and a control unit 136.
Here, the antenna 131 and the transmission / reception unit 132 perform transmission / reception of radio waves in accordance with each communication method of the mobile communication terminal 101, perform transmission / reception with other mobile communication terminals 104, and in particular, from the content server 105. The content is received, and transmission permission information is received from the transmission permission apparatus 102.

  As each communication system of the transmission / reception part 132, W-CDMA (Wideband Code Division Multiple Access) is mentioned, for example. The W-CDMA transmission / reception unit 132 includes a demultiplexer / coupler, an oscillator, a PLL (Phase Locked Loop), a modulation / demodulation unit, spreading / despreading for baseband signal processing, a Rake receiver, and the like.

Further, the transmission / reception unit 132 has infrared communication, Bluetooth, and a wireless LAN function.
Further, the encoding / decoding unit 133 performs encoding / decoding of transmission / reception data, and uses an encoding / decoding scheme according to each communication scheme of the mobile communication terminal 101 or a format of transmission / reception data. .

Examples of the encoding / decoding unit 133 include PCM (Pulse Code Modulation) and AMR (Adaptive Multi Rate) as long as it is transmission / reception data for voice calls.
Also, if the transmission / reception data for multimedia communication is 3G-324M, H.264. 263, MPEG (Moving Picture Experts Group) -4, MPEG-2, and the like.

As described above, encoding / decoding processing is performed by various encoding / decoding methods. Some transmission / reception data does not require processing in the encoding / decoding unit 133.
Furthermore, the storage unit 134 stores transmission / reception data. In particular, the storage unit 134 stores content received from the content server 105 and stores transmission permission information received from the transmission permission device 102.

Examples of the storage unit 134 include a ROM (Read Only Memory), a RAM (Random Access Memory), an IC (Integrated Circuit) card, a memory card, a memory card with a copyright protection function, and a disk device.
The input / output unit 135 functions as an external interface in the mobile communication terminal 101. Examples of the input / output unit 135 include a communication device such as a microphone and a speaker, a display device such as an LCD (liquid crystal display unit), an input device such as a CCD (charge coupled device) camera, and a data communication interface. USB (Universal Serial Bus), IEEE1394, Bluetooth, etc. are mentioned.

The input / output unit 135 has a function of performing voice recognition processing on voice information and reading image information such as a barcode.
The control unit 136 controls various processes in the mobile communication terminal 101, and includes a content / transmission permission information acquisition unit 137 that performs control related to communication, and a transmission determination unit 138 that determines whether transmission is possible. The content / transmission permission information acquisition unit 137 and the transmission determination unit 138 are configured by software.

Here, the content / transmission permission information acquisition unit 137 controls the transmission / reception unit 132, the encoding / decoding unit 133, and the input / output unit 135, and particularly performs transmission / reception with the content server 105 and the transmission permission device 102.
Furthermore, the transmission determination unit 138 determines whether or not transmission to another mobile communication terminal 101 is possible when content is received from the content server 105 via the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101.

For this reason, when receiving content from the content server 105, the transmission determination unit 138 requests transmission permission information from the transmission permission device 102 and acquires it from the content server 105 based on the transmission permission information received from the transmission permission device 102. The transmission permission / rejection is determined with respect to transmitting the content to the other mobile communication terminal 104.
As a result, even if the mobile communication terminal 101 receives the content from the content server 105, the mobile communication terminal 101 cannot transmit the content unconditionally to the other mobile communication terminal 104, and requests transmission permission information from the transmission permission device 102. The content acquired from the content server 105 can be transmitted to another mobile communication terminal 104 only when the transmission permission information is received from the transmission permission device 102, but the transmission permission information is requested from the transmission permission device 102. Nevertheless, if the transmission permission information cannot be received from the transmission permission device 102, the content acquired from the content server 105 cannot be transmitted to another mobile communication terminal 104.

When the transmission permission information is displayed as image information including a barcode on the display board of the transmission permission device 102, the image is captured by the camera of the input / output unit 135, the image information is read, and the transmission permission information is acquired. .
Furthermore, when transmission permission information is output as sound information from the sound output device of the speaker of the transmission permission device 102, the sound information is input by the microphone of the input / output unit 135, the sound information is subjected to sound recognition processing, and transmitted. Get permission information.

  FIG. 3 is a diagram showing a configuration of content data transmitted by the content server 105 in FIG. As shown in the figure, the content data transmitted from the content server 105 is composed of a header portion indicating the content main body information and a payload portion which is the content main body, and the content includes music, video, games, and the like. Examples include content, content delivered by electronic commerce, so-called “rich content”.

FIG. 4 is a diagram showing a distance relationship between the transmission permission apparatus 102 and the mobile communication terminal 101 in FIG. Although the transmission permission device 102 transmits a signal of transmission permission information, as described above, since the reachable range is a short distance, as shown in FIG. And
When the mobile communication terminal 101 is located at A within the reachable range X, the mobile communication terminal 101 can receive within the reachable range X of the transmission permission information signal transmitted from the transmission permission device 102. In this case, the transmission determination unit 138 of the mobile communication terminal 101 determines that content transmission is possible in response to a request for content transmission permission information.

When the mobile communication terminal 101 is located in B outside the reachable range X, the mobile communication terminal 101 is outside the reachable range X of the transmission permission information signal sent from the transmission permitting device 102 even if it tries to send a transmission permission information. , Reception is impossible. In this case, the transmission determination unit 138 of the mobile communication terminal 101 determines that the content cannot be transmitted in response to the request for the content transmission permission information.
FIG. 5 is a flowchart for explaining an operation example of the content server 105 in FIG. As shown in the figure, in step 201, the content server 105 determines whether or not there is a transmission request under the control of the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101. If there is no transmission request, the process ends.

In step 202, when there is a transmission request, the content server 105 transmits the content to the mobile communication terminal 101, and the mobile communication terminal 101 stores the content received under the control of the content / transmission permission information acquisition unit 137. In step 134, the process is terminated.
FIG. 6 is a flowchart for explaining an operation example of the transmission permission apparatus 102 in FIG. As shown in this figure, in step 211, the transmission permission apparatus 102 determines whether or not there is a transmission request under the control of the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101. If there is no transmission request, the process ends.

In step 212, when there is a transmission request, the transmission permission device 102 transmits the transmission permission information to the mobile communication terminal 101, and the mobile communication terminal 101 transmits the transmission received under the control of the content / transmission permission information acquisition unit 137. The permission information is saved in the storage unit 134, and the process is terminated.
FIG. 7 is a sequence diagram illustrating an operation example of the mobile communication system in FIG. As shown in this figure, in sequence 221, a content transmission request is sent to the content server 105 under the control of the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101.

  In sequence 222, the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101 receives and acquires content from the content server 105. The acquired content is displayed on the input / output unit 135 built in the mobile communication terminal 101, and the acquired content is stored in the storage unit 134. These reception, display, and storage are performed by known operations of the mobile communication terminal 101.

In sequence 223, when the user of mobile communication terminal 101 desires to transmit the content acquired from content server 105 to another mobile communication terminal 104, the content / transmission permission information acquisition unit of mobile communication terminal 101 Under the control of 137, a transmission request for content transmission permission information is made to the transmission permission apparatus 102.
In sequence 224, transmission permission information is received from the transmission permission device 102 under the control of the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101.

  In sequence 225, the transmission determination unit 138 of the mobile communication terminal 101 determines that the content can be transmitted when the transmission permission information is received. If the transmission permission information is not received from the transmission permission apparatus 102 in spite of a transmission request to the transmission permission apparatus 102, it is determined that the content cannot be transmitted. This makes it possible to maintain content rarity.

  In sequence 226, when the transmission determination unit 138 of the mobile communication terminal 101 determines that the content can be transmitted, the movement as a transmission destination is controlled by the content / transmission permission information acquisition unit 137 of the mobile communication terminal 101. The content acquired from the content server 105 is transmitted to the body communication terminal 104 via the mobile communication network 103.

  Therefore, according to the present invention, since the mobile communication system including the mobile communication terminal 101, the transmission permission device 102, and the content server 105 is constructed, the mobile communication terminal 101 receives the transmission permission information from a specific place. Based on whether or not transmission is possible and content from the content server 105 is limited, it is transmitted to other mobile communication terminals 104 only.

That is, content is unconditionally transmitted to the mobile communication terminal that directly accesses the content server 105, but the content acquired from the content server 105 is transmitted between the mobile communication terminals without passing through the content server 105. There was a restriction.
In this way, to attract customers at stores, sightseeing spots, etc., management of attractive content that can be received only at the shops and sightseeing spots using the mobile communication system described above, where the reception range is short-range. , Protection and ability to attract customers.

  Stores, sightseeing spots, etc. possess content that is attractive to customers, and limit the places where content can be transmitted from the mobile communication terminal of the customer who received the content to other mobile communication terminals. Can be made to gather. As a result, it is possible to maintain the rarity of the content because it can be transmitted only at a specific place, manage and protect it, and enhance the ability to attract customers.

Some contents held by the content server 105 should be kept scarce and some contents may not be kept. The handling in this case will be described below.
FIG. 8 is a modification of FIG. 3 and is a diagram showing another configuration of content data transmitted by the content server 105. As shown in FIG. 5A, a content ID well known in the content distribution technology exists in the header portion of the content transmitted by the content server 105, and whether or not content transmission determination is necessary for this content ID. Add information indicating.

That is, as shown in FIG. 5A, when content rarity is to be maintained, information on the necessity of transmission determination is added to the content ID in the header portion of the content.
As shown in FIG. 5B, when it is not necessary to maintain the rarity of content, information that does not require transmission determination is added to the content ID in the header portion of the content.
Note that the transmission determination unit 138 of the mobile communication terminal 101 has a function of determining whether transmission determination is included in the content ID when content is received from the content server 105.

FIG. 9 is a flowchart for explaining an example of the operation of determining the transmission determination necessity information included in the content ID of FIG. 8 in the operation of the mobile communication system of FIG. As shown in this figure, in step 231, the mobile communication terminal 101 accesses the content server 105 via the content / transmission permission information acquisition unit 137 and receives the content.
In step 232, the mobile communication terminal 101 determines whether the content ID of the content received via the content / transmission permission information acquisition unit 137 includes information that requires transmission determination in the transmission determination unit 138. If the transmission determination unit 138 determines that the information does not require transmission determination, the process proceeds to step 235.

That is, when transmission determination is unnecessary, transmission permission information is not required from the transmission permission device 102, and content can be transmitted from the mobile communication terminal 101 to another mobile communication terminal 104 unconditionally.
In step 233, when the transmission determination unit 138 determines that the transmission determination necessary information is included, the content transmission permission information acquisition unit 137 of the mobile communication terminal 101 transmits the content transmission permission information to the transmission permission device 102. Request.

In step 234, the transmission determination unit 138 of the mobile communication terminal 101 determines whether the content / transmission permission information acquisition unit 137 has received and acquired the transmission permission information from the transmission permission device 102. If the transmission permission information is not received, the process ends.
That is, in the case of content that requires transmission determination, when transmission permission information cannot be obtained, transmission from the mobile communication terminal 101 to another mobile communication terminal 104 is restricted. This makes it possible to maintain content rarity.

In step 235, when the transmission permission information is received by the content / transmission permission information acquisition unit 137, the transmission determination unit 138 determines that transmission is possible, and transmission of content from the mobile communication terminal 101 to another mobile communication terminal 104 is performed.
