  The terminal condition data is data for grouping users. The terminal condition data includes stay time, user behavior history, user attributes, and the like. The terminal condition data can be changed as appropriate by user operation or control by the control unit 16.

The stay time is an elapsed time after the user terminal 10 enters the communication area of the AP 20 and is updated sequentially.
The user's behavior history is updated, for example, when a coupon that can be used at a predetermined store is used using a user terminal, or when a payment process is performed by the user terminal 10 using electronic money or the like. It is data. The coupon is an electronic coupon that can be downloaded from a store via the Internet, for example, and can be used in the store using a dedicated reader installed in the store when purchasing a product. .
The user attribute is, for example, data indicating whether the user is a member or a nonmember in a predetermined store and whether a store-dedicated application is installed. Note that the user attributes may include personal data of the user such as sex, age, place of residence, workplace, etc.

  The control unit 16 includes an arithmetic circuit such as a CPU (Central Processing Unit) and a storage circuit such as a RAM (Random Access Memory), and controls each unit of the user terminal 10. The control unit 16 expands a program (software) such as a dedicated application from the programs stored in the storage unit 15 and the like, and executes various processes in cooperation with the program expanded in the RAM.

A more detailed description of various functional configurations implemented by the control unit 16 will be described later.

[Access point configuration]
FIG. 3 is a block diagram showing a schematic configuration of the AP 20.
The AP 20 is a wireless LAN access point installed in various places such as stores and public transportation. The AP 20 is connected to the server device 30 so as to be able to communicate with each other. In this embodiment, the AP 20 is connected via a WAN such as the Internet.
As shown in FIG. 2, the AP 20 includes a wireless LAN communication unit 21, a WAN communication unit 22, an AP storage unit 23, and an AP control unit 24.

  The wireless LAN communication unit 21 is a wireless communication unit of the present invention, and communicates with the user terminal 10 in a predetermined communication area. In addition, the wireless LAN communication unit 21 periodically transmits a beacon signal having parameters necessary for connection in the communication area. The beacon signal includes various parameters such as identification data (ESSID and / or MAC address), signal transmission method, security method, and the like.

The WAN communication unit 22 is connected to a WAN (Wide Area Network) such as the Internet.
The AP storage unit 23 includes a memory such as a RAM and a recording medium such as a hard disk, and stores various programs and various data. In addition, the AP storage unit 23 records terminal data and the like of the user terminal 10 in which communication connection is established by wireless communication.

  The AP control unit 24 includes, for example, an arithmetic circuit such as a CPU or MPU and a storage circuit such as a RAM. Then, the AP control unit 24 performs various processes by expanding the program stored in the storage unit such as the AP storage unit 23 on the RAM, and functions as the terminal data acquisition unit 241, the IP allocation unit 242, and the like. .

  The terminal data acquisition unit 241 acquires the terminal data of the user terminal 10 for which communication by the wireless LAN has been established, and stores it in the AP storage unit 23. Here, examples of the terminal data include the terminal ID of the user terminal 10 and the radio wave intensity of a radio wave transmitted from the user terminal 10. Note that the terminal data related to the user terminal 10 whose communication has been disconnected is deleted from the AP storage unit 23.

  The IP allocation unit 242 allocates an IP address to the user terminal 10 that is communicating with the wireless LAN communication unit 21 based on the terminal data stored in the AP storage unit 23. That is, the AP 20 functions as a DHCP. Thereby, communication connection between apparatuses, such as DLNA (Digital Living Network Alliance), is attained between each user terminal 10, for example.

[Configuration of server device]
FIG. 4 is a block diagram illustrating a schematic configuration of the server device 30.
The server device 30 is configured by a computer and functions as a back end in the content publishing system 1.
The server device 30 includes a server communication unit 31, a server storage unit 32, a server control unit 33, and the like.

  The server communication unit 31 communicates with each user terminal 10 and the AP 20. The server communication unit 31 is connected to a WAN such as the Internet via, for example, a LAN, and communicates with the user terminal 10 and the AP 20 via the WAN. The connection between the server device 30 and the user terminal 10 may be, for example, a connection through the AP 20 or may be connected from the WAN without using the AP 20.

  The server storage unit 32 is a data recording device configured with, for example, a memory, a hard disk, and the like. The server storage unit 32 stores a position determination database, a user database, a group setting database, and the like. In addition, the music data transmitted from the user terminal 10 is stored. Further, the server storage unit 32 stores various programs for controlling the server device 30.

  For example, as shown in Table 1 below, the position determination database is a database in which identification data, area data corresponding to the identification data, and area ID are associated with each other. As the identification data, the identification data of the AP 20 (ESSID in this embodiment) is recorded. The area data indicates the position of the communication area corresponding to the identification data, and stores, for example, a store name, a tourist spot, a station, public transportation, a building name, and the like. The area ID is data for identifying area data.

As in the area data “A coffee shop: A1 branch” corresponding to the identification data “SSID: A1” shown in Table 1, area data is associated with each identification data.
Further, like the area data “A coffee shop: A2 branch” for the identification data “SSID: A2” and “SSID: A3”, the same one area data may be associated with a plurality of identification data. .
Furthermore, the location of one facility may be divided into a plurality of areas, such as area data “University D: Cafeteria” and “University D: Library” for identification data “SSID: D1” and “SSID: D2.”

The user database is a database in which a user terminal in which a dedicated application is installed is recorded. The user ID, the security password at the time of login, the terminal condition data transmitted from the user terminal 10, the transmitted identification data of the AP 20, the terminal identification Data, allocation group ID, etc. are recorded.
The user ID is an ID for identifying the user, and the security password is a password for the user to use the content publishing system 1. The terminal identification data is address data set uniquely for the user terminal 10 and is, for example, a MAC address. The allocation group ID is an ID for identifying a group allocated to the user terminal.
This user database is appropriately updated by data transmission from the user terminal 10 and control of the server control unit 33 described later. Instead of the identification data of the AP 20, area data determined from the position database, an area ID, or the like may be recorded.

The group setting database records conditions for grouping user terminals 10 in a predetermined area. Specifically, as shown in Table 2 below, area data (area ID) , group conditions, group ID, and the like are recorded.

The area ID corresponds to each area ID in the position determination database.
The group condition is a condition of a group to be set, and a condition to be satisfied as terminal condition data of the user terminals 10 to be grouped is recorded.
The group ID is data for specifying a group to be set.
Here, as a condition, for example, a single condition may be recorded, such as a group condition for area IDs “A1”, “A2”, and “B” in Table 2, and a plurality of conditions may be recorded as in area ID “C”. These conditions may be recorded.
In the present embodiment, an example is shown in which the position determination database and the group setting database are different databases. However, for example, a database in which identification data is recorded in the group setting database may be used.

  The server control unit 33 includes an arithmetic circuit such as a CPU and a storage circuit such as a RAM. The server control unit 33 expands a program (software) stored in the server storage unit 32 or the like in the RAM and cooperates with the program expanded in the RAM. Various processes are executed by operation. And the server control part 33 functions as the data acquisition means 331, the group setting means 332, and the group communication permission means 333 as shown in FIG. 4 by performing the said various processes.

The data acquisition unit 331 acquires the AP 20 identification data and terminal condition data transmitted from each user terminal 10.
The group setting unit 332 sets a group of user terminals 10 belonging to the communication area of each AP 20 using the acquired identification data and terminal condition data and each database in the server storage unit 32.
The group communication permission unit 333 transmits group license data for permitting sharing of music data between the user terminals 10 in the set group to each user terminal 10. Further, the same group license data may be transmitted to the AP 20.

[Operation of content publishing system]
Next, specific processing operations of the content publishing system 1 as described above will be described with reference to the drawings.
(Initial processing)
FIG. 5 is a flowchart showing an initial process in the content publishing system 1.
In order to use the content publishing system 1 of the present embodiment, a dedicated application needs to be installed in the user terminal 10.
When the dedicated application is installed in the user terminal 10, the list generation unit 164 reads the music data stored in the storage unit 15 and generates a playlist that lists each music data (step S101).
The music data to be listed may be all music data stored in the storage unit 15 or only music data specified by a user operation.
Note that the processing in step S101 is performed, for example, when new music data is stored in the storage unit 15, for example, in addition to when the dedicated application is installed (initial processing).

Further, the content registration unit 163 reads the music data stored in the storage unit 15 and transmits it to the server device 30 (step S102). The transmission to the server device 30 may be communication via the first communication unit 141 or communication via the second communication unit 142.
Note that the process of step S102 is performed, for example, when new music data is stored in the storage unit 15, for example, in addition to the initial process.

  On the other hand, when receiving the music data transmitted from the user terminal 10 (step S201), the server device 30 stores the received music data in the server storage unit 32 as master data (step S202). That is, if the server device 30 already stores in the server storage unit 32 data that matches the received music data, for example, the ID, song name, artist name, genre, audio data size, etc. No storage is performed, and only new music data is stored.

(AP detection process)
FIG. 6 is a flowchart showing the terminal condition data transmission process from the AP 20 detection process performed in the user terminal 10.
The communication control means 161 of the user terminal 10 determines whether or not the first communication unit 141 has received a beacon signal from the AP 20 (step S103). This beacon signal detection determination process is periodically performed, for example, at predetermined time intervals.
In step S103, when no beacon signal is received (step S103; No), step S103 is continued and detection of the beacon signal is continued.

On the other hand, when a beacon signal is received from the AP 20 in step S103 (step S103; Yes), the communication control means 161 detects the signal strength of the beacon signal received by the first communication unit 141 (step S104). It is determined whether the signal strength is equal to or higher than a predetermined value set in advance (step S105).
In step S105, when the signal strength is less than the predetermined value (step S105; No), the process returns to step S103.

In step S105, when the signal strength is equal to or higher than the predetermined value (step S105; Yes), it is determined that the user having the user terminal 10 has entered the communication area of the AP 20.
In this case, the communication control means 161 controls an internal timer (not shown) to measure the elapsed time during which a beacon signal having a signal strength equal to or higher than a predetermined value is detected (step S106), and the terminal of the storage unit 15 Record the stay time of the condition data.
Moreover, the communication control means 161 detects the identification data of AP20 from the received beacon signal (step S107).

(Terminal condition data transmission processing)
By the way, in the user terminal 10, terminal communication settings are set in advance, for example, “priority for mobile phone communication network”, “priority for communication via wireless LAN”, and the like. In addition, as a setting of the dedicated application, it is possible to select, by user operation, “to perform via a connection between devices (for example, DLNA)” or “to perform through a server” for transmission of a playlist shared within the group. .
The communication control unit 161 determines whether or not “prioritize communication via wireless LAN” is set in the terminal communication setting (step S108). If it is determined in step S108 that communication via the wireless LAN is prioritized (step S108; Yes), the communication control means 161 transmits terminal data to the AP 20, and the first communication unit 141 and the wireless LAN of the AP 20 A communication connection with the communication unit 21 is established (step S109). Thereby, the user terminal 10 is switched from the communication connection using the mobile phone communication network to the communication connection connected to the WAN from the WAN communication unit 22 of the AP 20 via the AP 20.

On the other hand, when “priority is given to the cellular phone communication network” is set in step S108 (step S108; No), the communication control unit 161 continues communication by the second communication unit 142.
After determining No in step S108 or after step S109, the group condition transmission unit 162 uses the AP 20 identification data and terminal condition data detected in step S107 as the MAC address for identifying the user terminal 10, It transmits to the server apparatus 30 with a user ID (step S110). Here, when step S109 is performed, each data is transmitted to the server device 30 via the AP 20, and when it is determined No in step S108, the mobile phone communication network by the second communication unit 142 is used. Each data is transmitted to the server device 30.

(Group setting process)
FIG. 7 is a flowchart showing group setting processing performed in the server device 30.
The data acquisition unit 331 of the server device 30 receives the identification data and terminal condition data of the AP 20 transmitted from the user terminal 10 in step S110 (step S203). And the data acquisition means 331 reads the data corresponding to the received user ID from a user database, and records the identification data and terminal condition data of AP20 (step S204).

Next, the group setting unit 332 groups the user terminals 10 existing in the communication area of each AP 20 using the position determination database, the user database, and the group setting database.
Specifically, the group setting unit 332 determines whether there is an area ID and area data corresponding to the identification data of the AP 20 transmitted from the user terminal 10 from the position determination database (step S205).
If it is determined in step S205 that there is no corresponding area ID (step S205; No), the group setting unit 332 ends the group setting process. In this case, a notification that the corresponding group does not exist (non-corresponding notification) is transmitted from the server device 30 to the user terminal 10 (step S206).

  On the other hand, if a corresponding area exists in step S205 (step S205; Yes), the group setting unit 332 acquires the area ID (step S207).

Next, the group setting unit 332 reads the group condition corresponding to the area ID from the group setting database, and determines whether there is a group condition corresponding to the terminal condition data transmitted from the user terminal 10 (step S208). ). In step S208, if there is no corresponding group condition (step S208; No), the same processing as in step S206 is performed, and a non-correspondence notification is transmitted from the server device 30 to the user terminal 10.
On the other hand, when there is a corresponding group condition in step S208 (step S208; Yes), the group setting unit 332 acquires a group ID corresponding to the group condition. Then, the acquired group ID is recorded in the assigned group ID corresponding to the corresponding user ID in the user database (step S209). That is, the group setting unit 332 sets a group to which each user terminal 10 belongs.

For example, when the identification data is “SSID: A1” in Table 1 and the terminal condition data indicates that “stay time is 20 minutes”, the group setting unit 332 first displays the table shown in Table 1. From such a position determination database, it is determined that the area ID corresponding to the identification data is “A1”. Thereafter, the group setting means 332 obtains the group conditions “stay time 5-30 minutes” and “stay time 30 minutes or more” corresponding to the area ID “A1” from the group setting database as shown in Table 2. get. The group setting means 332 sets the group ID “Ga1-1” corresponding to the group condition of “stay time 5-30 minutes” because “stay time 20 minutes” is recorded in the terminal condition data. .
A plurality of conditions may be set as the group condition. For example, when the group condition is a member as in the area ID “C” of Table 2, the group ID “Gc1-1” is assigned, and the fee paid by electronic money or the like is 1000 or more. Is assigned a group ID “Gc1-2”.

Thereafter, the group communication permission means 333 extracts data in which the assigned group ID is recorded from the user database, sets the user IDs having the same assigned group ID as one group, and generates group license data (step S210).
This group license data is data for permitting sharing of content data (music data) between user terminals 10 belonging to the same group, and is generated for each group. This group license data is generated for the group when the allocation group ID is recorded in step S209. Accordingly, when a new user enters the communication area of the AP 20 and the user terminal 10 satisfies the group condition, new group license data is generated each time. This group license data includes area identification data corresponding to the group ID and terminal identification data of each user terminal 10 belonging to the group.
Then, the group communication permission unit 333 outputs a notification (group notification) that the corresponding group license data and sharable music data exist to each user terminal 10 belonging to each group (step S211). ).

(Terminal process that received the notification)
FIG. 8 is a flowchart showing processing of the user terminal 10 after receiving the notification.
When the user terminal 10 receives each notification from the server device 30 (step S111), the user terminal 10 performs a process according to the notification.
Specifically, the communication control unit 161 determines whether or not the received notification is the group notification transmitted in step S211 (step S112).
In step S112, when the notification is a non-correspondence notification transmitted in step S206 (step S112; No), the user terminal 10 returns to the process of step S103 in FIG.

When the communication control unit 161 determines that the notification is a group notification (step S112; Yes), the list transmission unit 165 refers to the terminal identification data of the user terminal 10 of the group license data received together with the group notification. The playlist is transmitted to the other user terminals 10 in the same group (step S113).
Further, since the playlist is transmitted from the other user terminals 10 in the same group, the communication control unit 161 receives these playlists, and the playlist management unit 168 indicates the received playlist and the reception date and time. It associates and stores in the memory | storage part 15 suitably (step S114).

As described above, transmission of a playlist can be set in advance as the setting of the dedicated application. Therefore, transmission / reception of a playlist by the list transmission unit 165 may be performed by communication via the AP 20 or communication via the server device 30 based on this setting, and may be performed between devices such as DLNA. It may be done by connection.
In communication via the AP 20, for example, the AP 20 receives and relists the playlist transmitted from each user terminal 10, and transmits the relisted playlist from the AP 20 to each user terminal 10. Also good.
In the case of using inter-device connection, other user terminals 10 in the group may not support the connection. In this case, for example, a process of automatically switching to communication via the AP 20 or communication via the server device 30 may be performed.

Thereafter, the display control unit 167 notifies the user that the music data of the other user terminal 10 can be reproduced by a push notification (step S115).
FIG. 9 is a screen indicating that a push notification has been output at the user terminal.
Specifically, the display control unit 167 performs notification by causing the display unit 11 to display a push notification 111 in which a text such as “music passing” is displayed in a notification box. Note that the notification is not limited to the display control unit 167, and the playback unit 166 outputs a predetermined notification sound from the audio output unit 13, or the display control unit 167 simultaneously performs the push notification and the notification unit 166 to output the notification sound. May be.

Thereafter, the user terminal 10 displays whether or not a tap operation has been performed on the push notification 111 displayed on the display unit 11 (selected by the user operation), or the top page of the dedicated application is displayed by the user operation. It is determined whether or not the above operation has been performed (step S116).
In step S116, if there is no tap operation on the push notification 111 or an operation for displaying the top page (step S116; No), the process returns to step S115 to continue the push notification. If a predetermined operation other than the tap operation of the push notification 111 and the operation for displaying the top page is performed, the push notification 111 may be hidden and the process may return to step S103.

On the other hand, when the tap operation of the push notification 111 or the operation for displaying the top page is performed (step S116; Yes), the display control unit 167 displays the top of the dedicated application as shown in FIG. The page 112 is displayed (step S117).
Specifically, as shown in FIG. 10, the display control means 167 displays the date and time 112D when the playlist is acquired, the area 112D, the artist name 112B, the jacket image 112C, etc. of the music data in the received playlist. The top page 112 in which the data 112E and the like are displayed for each music data is displayed. Here, when the user performs a user operation to vertically scroll the screen, for example, the display control unit 167 slides the displayed music data in the vertical direction, for example, and displays other music data.

Further, the user terminal 10 determines whether or not a user operation for selecting predetermined music data, such as a jacket image 112C being tapped, is performed by a user operation (step S118). In this step S118, when there is no user operation (step S118; No), it returns to the process of step S117 and continues displaying the top page 112.
On the other hand, when music data is selected by a user operation (step S118; Yes), the display control means 167 displays a music data reproduction page 113 as shown in FIG. 11 (step S119).
In the music data reproduction page 113, the display control unit 167 displays, for example, a reproduction button 113A, a music purchase application cooperation button 113B, and a possession state display unit 113C.
Here, the possession state display unit is a display indicating whether or not the corresponding music data is stored in the storage unit 15, and when stored in the storage unit 15, the display control unit 167 displays, for example, “owned music”. Display. If not stored, for example, the purchase cost of the audio data is displayed.

  When the reproduction button 113A is selected by a user operation, for example, by tapping, the reproduction unit 166 causes the audio output unit 13 to output the audio data of the music data. At this time, the reproduction unit 166 downloads the audio data from the server device 30 and performs streaming reproduction when the audio data is not stored in the storage unit 15 and the corresponding music data is in the playlist with the latest reception date and time. Let That is, the user can share and listen to music data provided from other user terminals 10 in the AP 20.

  When the music purchase application cooperation button 113B is selected by a user operation, for example, by tapping, the user terminal 10 activates other application software such as a browser to purchase music. Display the purchase screen. When the user performs a predetermined operation on the purchase screen, the music data is charged with respect to the seller, and the music data is downloaded and stored in the storage unit 15.

As described above, the above-described AP 20 detection process (step S103 to step S107) is also performed in the background while each process (step S111 to step S119) of the user terminal 10 after receiving the notification is being performed. ), Terminal condition transmission processing (step S110) is performed, and group setting processing (step S203 to step S212) is also performed in the server device 30.
Therefore, even when the top page 112 and the music data playback page 113 are displayed as described above, when a new user terminal 10 joins the group, or when the terminal condition data changes (for example, the stay time changes). ) Etc., new group license data is transmitted. Thereby, the playlist and music data shared within the group change in real time.

(Processing when user terminals belonging to a group change)
Even when the user terminal 10 in the communication area of the same AP 20 is out of the communication area and does not satisfy the group condition, the group license data corresponding to this is newly transmitted from the server device 30 as described above. The
When the playlist management unit 168 acquires a new playlist, the playlist management unit 168 accumulates and stores the previously acquired playlist in the storage unit 15. If the music data is listed only in the playlist whose reception date and time is not the latest and there is no music data in the storage unit 15, the playback button 113A is operated on the music data playback page 113 as described above. But I can't listen to it by streaming.
However, when the user enters the communication area of the AP 20 again, the group license data is issued again, and streaming playback is possible. In this case, when the AP 20 leaves the communication area, the music being played may be paused, and when returning to the communication area again, the music may be played continuously.

  In addition, since the playlist is stored in the storage unit 15, for example, when the user returns home, the date, place, and music data at which the playlist was acquired can be confirmed. In addition, when the music purchase application cooperation button 113B is selected in a state where the music data reproduction page 113 is displayed by the display control means 167, the music data can be purchased.

[Operational effects of this embodiment]
In the present embodiment, the user terminal 10 includes a storage unit 15 that stores music data that is content data and terminal condition data in which conditions for setting a group are recorded. Then, the communication control unit 161 of the user terminal 10 acquires the identification data of the AP 20 as the position data by the first communication unit 141, and the group condition transmission unit 162 transmits it to the server device 30 together with the terminal condition data.
In the server device 30, when the identification data and the terminal condition data are received by the data acquisition unit 331, the group setting unit 332 sets a group that permits communication between the user terminals 10 in the same area. The group communication permission unit 333 transmits group license data in which address data and the like necessary for mutual communication are recorded to each user terminal 10 in the group. Then, the user terminal 10 transmits the playlist generated by the list generation unit 164 to other user terminals 10 belonging to the group.
For this reason, for example, if the AP 20 is installed in a store such as a coffee shop, in public transportation, in various spots such as a station, a university, and a tourist spot, the user terminals 10 in the communication area of the AP 20 of the spot , Can share and check each other's playlist.

In the present embodiment, the user terminal 10 transmits the identification data of the AP 20 to the server device 30 as position data. That is, the grouping area is set using the AP 20 as a sensor for detecting the position.
In such a configuration, for example, the position can be detected more favorably in a room, underground, or the like as compared with a case where position data is acquired using a satellite signal such as a GPS (Global Positioning System) satellite. In addition, in public transportation such as trains and buses, when a position is acquired by a GPS satellite or the like, the position changes with time, and it becomes difficult to group user terminals. On the other hand, when the identification data of the AP 20 is used, since the identification data does not change even if the public transportation has moved, the area data of the communication area can be easily determined by the position setting database as described above. It is possible to improve the processing efficiency.

Further, the user terminal 10 determines that the AP 20 is detected and the user terminal 10 has entered the communication area when the signal strength of the beacon signal is equal to or greater than a predetermined value in the AP 20 detection process.
Therefore, for example, it is possible to avoid inconvenience such as detecting the identification data of the AP 20 of another store adjacent to the store where the user is present, and to set an appropriate communication area group according to the position of the user terminal 10. it can.

In the present embodiment, the group setting unit 332 sets user terminals that have the same identification data of the AP 20 and whose terminal condition data satisfies the group condition in the same group.
For this reason, it is possible to confirm what kind of music is being auditioned between users in the same area, that is, other users in the same situation.

In the present embodiment, the stay time after the user terminal 10 enters the communication area is one of the terminal condition data.
Then, for example, when the stay time is set as the group condition, the group setting unit 332 sets the group with reference to the stay time recorded in the terminal condition data.
In this case, for example, it is possible to prevent grouping of the user terminals 10 that have just entered the communication area of the AP 20 but have just passed.

Further, as in area IDs “A1” and “A2” shown in Table 2, a plurality of groups may be set according to the staying time. In this case, groups can be set according to the staying time. For example, a user who stays at a coffee shop for a long time is likely to be working other than meals such as studying in the store, and by grouping such users, users in the same situation can be Can be grouped.
Further, for example, the number of user terminals 10 belonging to the group can be controlled by dividing the group into long-term visitors and short-term visitors, and the number of playlists to be acquired is limited, so that the user terminals 10 The processing load can be reduced.

In this embodiment, the user's action history is one of the terminal condition data.
Thereby, a group can be set according to the action which the user performed. In this case, music can be shared between users having the same purpose.
For example, a specific service can be provided to a user who includes, in the terminal condition data, an action history such as using a coupon or purchasing a product using electronic money. In this case, for example, the group license data is also transmitted to the AP 20 or a store terminal installed in the AP 20 (which may have the same configuration as the user terminal 10). Thereby, for example, discount information can be push-distributed from the AP 20 or the store terminal to the user terminals 10 of the group having a predetermined action history, and a service for a specific group can be provided.

In the present embodiment, the user attribute is one of the terminal condition data.
Thereby, a group can be set based on attribute data, such as a user's state, for example, a user is a member of a specific store, or a reservation customer. Even in this case, a specific service can be provided to a specific user in the same manner as the user action history.

  In the present embodiment, the music in the playlist can be reproduced by the reproducing means 166, and the music can be temporarily shared. Thereby, in the same situation in the same area, it is possible to audition what kind of music the other person is listening to, and the user's interest in music can be increased. In such a configuration, for example, a user terminal 10 storing music data composed or performed by a composer or a performer is installed in the communication area of the AP 20 to promote the music data to many users. Can also produce a great advertising effect.

[Modification]
In addition, this invention is not limited to embodiment mentioned above, In the range which can achieve the objective of this invention, the deformation | transformation shown below is also included.

[Modification 1]
In the above embodiment, the user terminal 10 acquires the identification data from the AP 20 as position data and transmits it to the server device 30. For example, the user terminal 10 is based on a satellite signal (for example, a satellite signal from a GPS satellite). A position detection unit that calculates a current position (longitude / latitude) may be provided, and the current position detected by the position detection unit may be transmitted to the server device 30.
In this case, the server device 30 stores, for example, a map, division range data indicating the area range of each division by dividing the map into a plurality of divisions, and area data of each division in association with each other as a database. . Thereby, it can be determined from the current position transmitted from the user terminal 10 to which area the user terminal belongs, and a group for each area can be set.

[Modification 2]
In the said embodiment, the example which groups what has predetermined terminal condition data among the user terminals 10 of the same area for every communication area of AP20 was shown.
On the other hand, it is good also as a structure etc. which group the user terminal 10 of the same situation even if it is not the communication area of the same AP20.
In this case, for example, as shown in Table 3 below, the situation setting is added to the position setting data stored in the server device 30.

In the example as shown in Table 3 above, the situation ID “A” is given to “A coffee shop”. The group setting means 332 determines the situation ID “A” for the identification data “SSID: A1”, “SSID: A2”, and “SSID: A3” of the AP 20 based on such position setting data.
Further, as the group setting database, a situation ID may be recorded instead of the area ID of Table 2 described above. Thereby, data having the group condition corresponding to the terminal condition data can be extracted from the data corresponding to the situation ID “A”, and the group ID can be acquired. In such a configuration, the user terminals 10 existing in the communication area of the AP 20 of A coffee shops across the country can be group-set as the same group.
In addition, although the example which sets the user terminal 10 in the communication area of AP20 of A coffee shop to a group was shown, for example, even if A coffee shop, B coffee shop, C coffee shop, etc. in Table 1 are matched with the same situation ID Good. That is, the user terminals 10 that include the same information (information of “coffee shop” in the above example) in the contents of the situation and area data (position data) may be grouped.
Thereby, what kind of music the user of the same situation is listening to can be acquired from other user terminals belonging to a wider area than in the above embodiment. In this case, transmission / reception of playlists between the user terminals 10 is performed via a WAN such as the Internet.

Furthermore, in the user terminal 10, it is good also as a structure which can select suitably whether the group setting using situation ID or the group setting using area ID is implemented. In this case, selection data for selecting either the area ID or the situation ID is included as the terminal condition data.
Since the server device 30 acquires the area ID in Table 3, the server device 30 may select whether to acquire the situation ID and acquire the group ID from the corresponding group setting database.

[Modification 3]
Furthermore, playback of content data may be restricted based on terminal condition data.
For example, in the example of the above embodiment, an example in which different group IDs are given according to the staying time has been shown, but music data reproduction may be further restricted according to the staying time.
In this case, the reproduction restriction data is stored in association with the group ID in the group setting database. For example, in Table 2, playback restriction data indicating “only one trial of music data” is associated with the group ID “Ga1-1” whose group condition is “stay time 5-30 minutes”. In addition, the reproduction restriction data “unlimited listening to music data” is associated with the group ID “Ga1-2” whose group condition is “stay time is 30 minutes or more”. Then, the group communication permission unit 333 transmits the reproduction restriction data to each user terminal 10 together with the group license data. In each user terminal 10, the reproduction means 166 restricts the reproduction of music data to a predetermined condition in accordance with the obtained reproduction restriction data.
In the above example, when the group is divided into a plurality of groups according to the stay time, the reproduction regulation is different. For example, the reproduction regulation is performed according to the user action history of the terminal condition data or the user attribute. It may be provided. In addition to the reproducible number of times, for example, the music reproducible time may be limited as the reproduction restriction data, and only a part of the audio data (for example, only the intro part) may be auditioned.

[Modification 4]
In the above embodiment, when the signal strength of the beacon signal from the AP 20 is equal to or greater than a predetermined value, it is determined that the signal belongs to the communication area of the AP 20 and the identification data and the terminal condition data are transmitted to the server device 30. On the other hand, the acquired identification data of the AP 20 may be transmitted to the server device 30 regardless of the signal strength of the AP 20.
In the server device 30, a group may be set using the radio wave intensity of the AP 20 as a group condition. In this case, the user terminal 10 transmits the terminal condition data including the acquired identification data of the AP 20 and the signal strength of the beacon signal output from the AP 20 to the server device 30.
In this case, an area for setting a group can be enlarged or reduced. For example, when it is desired to set only the user terminals 10 in a narrow area as a group, the user terminals 10 whose signal intensity of the beacon signal from the AP 20 is equal to or greater than a threshold value may be grouped.

[Modification 5]
The present invention can also be used as an affiliate when purchasing music data.
For example, the user A selects the music data listed in the playlist of the user B, selects the music purchase application cooperation button 113B as shown in FIG. 11, and purchases the music data from the sales site. Here, the user ID of the user B, the payee, the payout method, etc. are recorded on the computer of the sales site. Further, the server device 30 records the user ID to which the music data is provided, and when the music data registered by the user B is purchased by the user A, the music data provided by the user B is stored on the computer of the sales site. Send affiliate data indicating purchase. Thereby, the computer of the sales site can determine that the purchase of the music data has been carried out by the introduction of the user B, and can pay the user B a reward.

[Modification 6]
In the above embodiment, the server apparatus 30 is connected to a plurality of APs 20 via a WAN such as the Internet, and user terminals in the communication area of these APs 20 are grouped. However, the present invention is not limited to this.
For example, the content publishing system 1 of the present invention may be applied to each individual store. In this case, the AP 20 and the server device 30 may be connected by wire.

[Modification 7]
In the above embodiment, music data is targeted as content data, but the present invention is not limited to this. As content data, for example, moving image data, still image data, digital content data such as comics and books (such as electronic books) can be targeted, and any digital content data can be targeted according to user operations. It is good also as a structure which can be selected suitably.

[Modification 8]
The position data may be the position in the virtual reality in addition to the identification data of the AP 20 and the latitude and longitude based on the satellite signal. For example, in a virtual reality such as a network game installed on the user terminal 10, when a character operated by a user exists in a predetermined game area, a group is set to share music data with other users in the area. May be set.
In this case, position data in the virtual reality is acquired from an application such as a network, transmitted to the server device 30, and users in the same virtual reality area in the same application are set as a group in the server device 30. . At this time, the dedicated music data of the application (network game) constituting the virtual reality may be transmitted to each user terminal 10 belonging to the group.

[Modification 9]
In the above embodiment, when the user operation for reproducing the music data is performed and the audio data is not stored in the storage unit 15, the audio data is downloaded from the server device 30 and is played back by streaming. However, the present invention is not limited to this. .
For example, the audio data of the selected music data may be received directly from another user terminal 10. In this case, for example, voice data may be received by connection between devices such as DLNA, voice data may be received via the AP 20, and voice data may be received via the WAN using the second communication unit 142. May be.

[Modification 10]
