Abstract

In order to download a content at high speed from a content delivery device (104) such as a kiosk terminal or the like to a mobile information terminal (101), the download of the content is started from a content server (102) to the content delivery device (104) before the mobile information terminal (101) approaches the content delivery device (104) to such a distance that the mobile information terminal (101) can directly communicate with the content delivery device (104) by using a high-speed wireless communication means (103). Therefore, the content delivery device (104), when detecting that an access point (106) located within the neighborhood area (107) of the content delivery device (104) starts to communicate with the mobile information terminal (101) by using a low-speed wireless communication means (105b), transmits a content download request to the content server (102). The content delivery device (104) temporarily stores the downloaded content and transfers the downloaded content to the mobile information terminal (101) by using the high-speed wireless communication means (103).

Description

Content reservation delivery system and content delivery device

The present invention relates to a content reservation distribution system for downloading content such as music, video information, and newspapers to a mobile communication device such as a portable information terminal, and a content distribution device in the content reservation distribution system.

In recent years, with the spread of high-speed wireless LAN technology such as IEEE 802.11, public wireless LAN services have been actively performed. This service places a wireless LAN access point at a place where people gather, such as a waiting room of a station and an airport, a coffee shop, etc., and passes the access point to a portable information terminal equipped with a wireless LAN interface possessed by the user. Internet connection service is provided. A high-speed wireless LAN such as IEEE802.11 has a short distance of about several tens of meters from an access point that can provide a service compared to a cellular wireless used in a cellular phone, but can transfer data at a higher speed than a cellular wireless. Therefore, a large amount of content such as music, video information, and newspaper can be downloaded to the portable information terminal in a short time.

In the future, there is a trend to create a high-speed download service as a new business using short-distance high-speed wireless technology using millimeter waves. In short-distance high-speed wireless communication using millimeter waves, the range in which service can be provided is a short distance of about several centimeters from the access point, but the data transfer rate is much higher than that of a conventional wireless LAN such as IEEE 802.11. It is extremely fast and can download large-capacity contents to a portable information terminal in a shorter time. As a high-speed download service using such radio, unlike a conventional public wireless LAN service, a wireless access point function is built into a kiosk terminal installed in various places in the city such as a station or a convenience store. In order to view content such as music, video information, and newspapers while moving, it is expected that content distribution services for downloading content in advance by bringing the mobile information terminal closer to the kiosk terminal will become mainstream.

However, in this type of service, even if the content download itself can be performed in a short time, the procedure before starting the download may take a long time.

Specifically, consider the case where content is downloaded at a kiosk terminal. After the user has approached the kiosk terminal, the user specifies the content information to be downloaded or user information necessary for processing such as charging from the kiosk terminal or the portable information terminal that can communicate with the kiosk terminal. Sent to the server to supply. After that, the content download to the portable information terminal is possible only after the download processing from the content server to the kiosk terminal is started. As described above, the user of the kiosk terminal must stop in front of the kiosk terminal for a longer time for specifying content information and transmitting the content to the content server in addition to the content download time via the network.

In order to solve such a problem, a content reservation distribution system is known in which content to be downloaded from a kiosk terminal to a portable information terminal is designated in advance. In this system, a portable information terminal is connected to a first wireless communication system (cellular telephone system) and a second wireless communication system having a smaller service area and a higher data transfer rate than the first wireless communication system. It has two wireless interfaces and transmits content download reservation information to the content server in advance via the cellular telephone system. Then, in response to the current position of the portable information terminal entering the service area of the second wireless communication system, a download request including use permission data is sent to the content server via the second wireless communication system. Send. The portable information terminal receives a previously reserved content download via the access point of the second wireless communication system (see Patent Document 1).
JP 2005-26977 A

However, in the conventional content reservation delivery system, the content download reservation is made in advance using the cellular telephone system, but the content download is actually started in the communication of the access point in the second wireless communication system. It is after recognizing that the portable information terminal has entered the range and transmitting a download request to the content server. For this reason, in order for the content to reach the access point from the content server, there is a delay corresponding to the transmission time on the Internet connecting the content server and the access point.

If the access point using a high-speed wireless LAN such as the current IEEE 802.11 is connected to a portable information terminal, the transmission speed between the access point and the portable information terminal is about several tens of megabits per second, and the Internet The delay time associated with transmission in the network is at a level that does not matter much. However, when the wireless communication system for downloading content to the portable information terminal in the future is changed to a high-speed wireless system using millimeter waves, the transmission speed between the access point and the portable information terminal may reach 1 gigabit per second. However, since the transmission speed between the access point and the portable information terminal is much higher than the data transmission speed on the Internet, the time required for the entire content download is governed by the data transmission delay time on the Internet. For this reason, there has been a problem that the advantage of the high-speed wireless communication system using millimeter waves cannot be utilized and the user cannot feel the advantage.

Realization of a new business called high-speed content download service using a high-speed wireless communication system using millimeter waves is difficult without solving this problem, and is an extremely important issue.

An object of the present invention is to solve the problems in the conventional content reservation delivery system and realize high-speed download of content to a portable information terminal by a high-speed wireless communication system using millimeter waves or the like.

In order to solve the above-mentioned conventional problems, the content reservation delivery system of the present invention communicates with the content server through the first wireless communication means capable of high-speed communication with a short communication distance, but slower than the first wireless communication means. An information terminal having two types of wireless communication means called a second wireless communication means having a long distance, and a function of downloading content from the content server via a network, and further, the information terminal and the first wireless communication A content distribution apparatus communicable by means, and a terminal detection apparatus communicable by the information terminal and the second wireless communication means and connected to the content distribution apparatus via a network.

As the first wireless communication means, a high-speed wireless communication system using millimeter waves can be used. When the content is reserved, the individual identification information of the information terminal that receives the content may be registered in advance. Further, the content distribution apparatus designates the terminal detection apparatus located in the vicinity of the content distribution apparatus in advance.

Further, the content distribution device detects the presence of the information terminal having the individual identification information specified as the content distribution terminal by the second wireless communication means, the terminal detection device specified in advance The information terminal recognizes that the information terminal exists in the vicinity of the content distribution device itself, and the information terminal is outside the communicable range by the first wireless communication means possessed by the content distribution device itself. However, a content download request designated at the time of content reservation is sent to the content server, and content download is started in advance.

According to the content reservation delivery system of the present invention, when the information terminal is sufficiently close to the content delivery device and the first wireless communication means can communicate with the information terminal and the content delivery device, The content has been downloaded from the content server to the content distribution device. As a result, the time required for downloading content from the content distribution apparatus to the information terminal can be shortened. Therefore, it is possible to realize a content reservation distribution system in which the content download time to the information terminal is short.
