When commuting, a user living in the city A goes to the station X with the portable terminal 400, gets on the train N at the station X, and gets off the train N at the nearest station Y of the company.
At this time, the mobile terminal 400 connects to the access point in each place of the city A, the station X, the train N, and the station Y, and acquires contents in each place.
Thereby, the user can obtain information on the place where the user is.

A predetermined SSID (Service Set IDentifier) is set in each access point of the city A, the station X, the train N, and the station Y. In order to facilitate the management of SSID, the same SSID (EKI) is set to access points installed in the same type of place (stations X and Y).
In addition, the SSID of each access point is set in advance in the user application of the mobile terminal 400. For example, the mobile terminal 400 downloads and stores a user application in which the SSID table of each access point is set. In addition, the mobile terminal 400 downloads and stores a new access point SSID table as update data of the user application.

The portable terminal 400 sequentially reads out a plurality of SSIDs stored in the SSID table one by one, and checks whether an access point with the same SSID as the read SSID exists in the wireless communication area.
When the corresponding access point exists, the portable terminal 400 acquires content by connecting communication with the access point.

Usually, the SSID is transmitted from the access point. And a portable terminal connects communication with the access point which transmitted SSID detected when the SSID transmitted from the access point was detected.
In the second embodiment, the SSID is not transmitted from the access point, but is stored in the mobile terminal 400 in advance. And the portable terminal 400 detects an access point spontaneously using SSID memorize | stored previously.

FIG. 6 is a functional configuration diagram of the mobile terminal 400 according to the second embodiment.
A functional configuration of portable terminal 400 in the second embodiment will be described with reference to FIG.

  The portable terminal 400 includes an access point connection unit 401, a content acquisition unit 402, a content display unit 403, an information posting unit 404, and a terminal storage unit 409.

  The access point connection unit 401 detects an access point using an SSID preset in the access point connection table (SSID table) 411, and connects the detected access point and communication.

  The content acquisition unit 402 communicates with the access point wirelessly and downloads content from the content distribution server (the in-vehicle server 200, the on-site server 300, or the city server 500) via the access point.

The content display unit 403 displays the content downloaded by the content acquisition unit 402 on the display.
In addition, the content display unit 403 generates audio data included in the content and outputs audio from the speaker.

  The information posting unit 404 communicates with the access point wirelessly and uploads post information input by the user to the content distribution server.

  The terminal storage unit 409 stores various data used by the mobile terminal 400 such as a user application, downloaded content, and access point connection table 411.

FIG. 7 is a flowchart showing an access method of content distribution system 100 according to the second embodiment.
An access method in which the portable terminal 400 accesses the access point will be described with reference to FIG.

  In S210, the user operates the mobile terminal 400 to activate the user application for the content distribution system 100 installed in the mobile terminal 400.

In S <b> 220, the mobile terminal 400 that has activated the user application connects communication with the access point of the content distribution system 100.
The mobile terminal 400 downloads content from a content distribution server (city server 500, local server 300 or in-vehicle server 200) via an access point connected to the communication, displays the downloaded content, and outputs audio of the content. .
Details of S220 (S221 to S227) will be described later.

  In S230, the user operates the mobile terminal 400 to end the user application.

Next, details of S220 (S221 to S227) will be described.
S221 to S227 are periodically executed while the user application is operating.

In step S221, the access point connection unit 401 selects one SSID from the access point connection table 411, and transmits the selected SSID wirelessly.
When each access point receives the SSID, each access point compares the received SSID with its own SSID. When the received SSID matches the own SSID, the access point wirelessly transmits response information indicating that the SSID matches.
For example, the access point connection unit 401 selects the first SSID “MACHI” set from the access point connection table 411 shown in FIG. 5 and transmits the selected SSID “MACHI” wirelessly. If the location where the SSID “MACHI” is transmitted is the city A, the response information is transmitted from the city access point 590 (MACHI), and if the location where the SSID “MACHI” is transmitted is the station X, the train N and the station Y, the access point. No response information is sent from.

In step S222, the access point connection unit 401 determines whether response information indicating that the SSIDs match can be received from the access point.
If the response information of the access point has been received (YES), the process proceeds to S223.
When the response information of the access point cannot be received (NO), the process returns to S221. In step S221, the access point connection unit 401 newly selects an unselected SSID and transmits the newly selected SSID.
S221 and S222 are repeatedly executed until response information is received from the access point or until there is no unsent SSID. When there is no unsent SSID and no response information can be received for any SSID, the access point connection unit 401 waits for the elapse of a predetermined time and executes S221 and S222 again.

  In S223, the access point connection unit 401 connects communication (connection) to the access point that transmitted the response information. When communication is connected, a communication method (for example, communication data encryption method) is determined between the access point connection unit 401 and the access point. In addition, a user ID and a password are transmitted to the access point by the access point connection unit 401 in order to authenticate the user. The user ID and password are input to the mobile terminal 400 by the user or preset in the mobile terminal 400. One combination of the user ID and the password may be set in the portable terminal 400 or may be set for each access point (SSID).

In S224, the information distribution unit of the content distribution server distributes the content via the access point.
The content acquisition unit 402 of the portable terminal 400 receives the content from the access point connected to the communication, and stores the received content in the terminal storage unit 409.

In S225, the access point connection unit 401 disconnects communication with the access point.
By disconnecting the communication with the access point once without continuing to connect, it is possible to prevent the wireless communication function of the portable terminal 400 from being monopolized. For example, after disconnecting communication with the access point, the user can connect the portable terminal 400 to the Internet until the next connection with the access point is established.

  In S226, the content display unit 403 displays the content stored in the terminal storage unit 409 on the display. If the content includes audio data, the content display unit 403 reproduces the audio data and outputs the audio from the speaker.

  In S227, the access point connection unit 401 stands by until a predetermined time has elapsed. After the predetermined time has elapsed, the process returns to S221.

Embodiment 3 FIG.
A content acquisition method will be described in which a category for which content is to be acquired is registered, and only the content of the category whose content has been updated among the registered categories is acquired.

FIG. 8 is a flowchart showing a content acquisition method of content distribution system 100 according to the third embodiment.
FIG. 8 shows a registered category table 412, an acquired content management table 413, and an in-vehicle content management table 218.
The content acquisition process (S224) described with reference to FIG. 7 will be described with reference to FIG.

  The terminal storage unit 409 of the portable terminal 400 stores a registration category table 412 and an acquired content management table 413.

  In the registered category table 412, “category ID” for identifying a category registered in the user application is set.

  In the description of the table shown in FIG. 7, content belonging to the category identified by the category ID is referred to as “the content”.

The acquired content management table 413 associates “server ID”, “category ID”, and “update ID”.
The server ID is information for identifying the content distribution server that distributed the content.
The update ID indicates the time when the content is updated (generated) in the format of “YYYYMMDDhhmmss”. “YYYY”, “MM”, “DD”, and “hh” indicate the year, month, day, hour, minute, and second.

A content management table is stored in the storage unit of the content distribution server (in-vehicle server 200, on-premises server 300, and street server 500). For example, the in-vehicle content management table 218 is stored in the in-vehicle information storage unit 209 of the in-vehicle server 200.
The content management table associates “category ID”, “information acquisition address”, and “update ID”.
The information acquisition address indicates an address that identifies a storage area in which the content is stored in a URI (Uniform Resource Identifier) format.

  Next, the content acquisition process (S224) will be described.

In S224-1, the content acquisition unit 402 of the mobile terminal 400 selects one category ID set in the registration category table 412.
For example, the content acquisition unit 402 selects the category ID “train information” set first in the registered category table 412.
Hereinafter, the selected category ID is referred to as “selected category ID”.

In S224-2, the content acquisition unit 402 of the mobile terminal 400 transmits the selected category ID to the access point.
The information distribution unit of the content distribution server receives the selected category ID via the access point and specifies content belonging to the category identified by the received selected category ID. The information distribution unit of the content distribution server transmits the identified content update ID (update time) to the mobile terminal 400 via the access point.
The content acquisition unit 402 of the portable terminal 400 receives the content update ID corresponding to the selected category ID from the access point.

For example, the content acquisition unit 402 of the mobile terminal 400 transmits the selected category ID “train information” to the in-vehicle server 200 via the in-vehicle access point 290 of the train N.
The in-vehicle information distribution unit 201 of the in-vehicle server 200 searches the in-vehicle content management table 218 to identify the update ID “2013039102900” corresponding to the selected category ID “train information”. The in-vehicle information distribution unit 201 of the in-vehicle server 200 transmits the specified update ID to the portable terminal 400 via the in-vehicle access point 290.
The content acquisition unit 402 of the mobile terminal 400 receives the update ID “2013039102900” corresponding to the selected category ID “train information” from the in-vehicle access point 290.

In S224-3, the content acquisition unit 402 of the mobile terminal 400 identifies an update ID corresponding to the selected category ID based on the acquired content management table 413.
The content acquisition unit 402 compares the identified update ID (current update ID) with the update ID received from the access point (latest update ID), and determines whether the content corresponding to the selected category ID has been updated.
If the current update ID is larger than the latest update ID (NO), the content has not been updated since the previous acquisition, and the process proceeds to S224-6.
If the latest update ID is greater than the current update ID (YES), the content has been updated since the previous acquisition, and thus the process proceeds to S224-4.

For example, when the selected category ID is “train information”, the current update ID is “201300328193000” in the acquired content management table 413 of FIG. 8, and the latest update ID is “2013039102900” in the in-vehicle content management table 218 of FIG. is there.
In this case, since “2010328193000 (current update time) <20133910102900 (latest update time)”, the content corresponding to the selected category ID “train information” is updated.

In S224-4, the content acquisition unit 402 of the mobile terminal 400 requests the content corresponding to the selected category ID from the content distribution server via the access point.
The information distribution unit of the content distribution server transmits the requested content (latest content) to the mobile terminal 400 via the access point.
The content acquisition unit 402 of the mobile terminal 400 receives the latest content from the access point. It is assumed that an update ID is set for the content.

  In S224-5, the content acquisition unit 402 of the mobile terminal 400 stores the received content in the terminal storage unit 409, and updates the update ID set in the acquired content management table 413 in association with the selected category ID as the latest content. Update with the set update ID.

In S224-6, the content acquisition unit 402 of the portable terminal 400 determines whether or not an unselected category ID remains in the registered category table 412.
If an unselected category ID remains (YES), the process returns to S224-1. The content acquisition unit 402 newly selects an unselected category ID in S224-1, and executes S224-2-5 for the newly selected category ID.
If all category IDs have been selected (NO), the content acquisition process (S224) ends.

  By the above processing, only updated contents that belong to the registered category among a large number of contents can be acquired. Thereby, useless communication can be reduced and power consumption can be reduced.
