Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
First, a first embodiment of the present invention will be described.
[1.1. Constitution]
FIG. 1 is a diagram showing an overall configuration of a communication control system 1 according to the first embodiment of the present invention. As shown in the figure, the communication control system 1 includes a mobile device 10 as a user terminal used by a user, a communication control device 20, a communication determination device 30, and a content provider 40. These devices are communicably connected via a communication network such as a mobile communication network or the Internet. The communication control device 20 and the communication determination device 30 relay communication between the mobile device 10 and the content provider 40.

  The mobile device 10 includes hardware such as a CPU (Central Processing Unit), a memory, a wireless communication interface, and operation keys. The software stored in the memory includes a program for performing HTTP (Hyper Text Transfer Protocol) communication. The mobile device 10 receives the requested content from the content provider 40 by transmitting / receiving an HTTP request / HTTP response to / from the content provider 40.

The content provider 40 is a server owned by the content provider, and distributes the content stored in the database to the mobile device 10. In response to the HTTP request from the mobile device 10, the content provider 40 returns an HTTP response via the communication determination device 30.
The communication determination device 30 includes a CPU, a memory, and a communication interface, and has a general computer hardware configuration. The memory stores a communication control condition determination program for each content type and a database for storing various data. The communication control device 20 also has a general computer hardware configuration. A communication control program is stored in the memory of the communication control device 20.

(Functional configuration)
The functional configuration of the communication control system 1 shown in FIG. 2 is realized by hardware and software resources included in the communication control device 20 and the communication determination device 30. Hereinafter, each component will be described.
The content correspondence communication control condition storage unit 11 is provided in the communication determination device 30 and stores information indicating a correspondence relationship between the type of content and the communication control condition.

In FIG. 3, an example of the information memorize | stored in the content corresponding | compatible communication control condition memory | storage part 11 is shown. Here, as the “content type”, for example, there are types such as a moving image, a Web page, an image, and a sound. The “communication control condition” is information representing a communication class or a communication speed.
Here, the communication class represents the degree of sharing a predetermined communication band. FIG. 4 is a diagram conceptually showing the degree of sharing the communication band. FIG. 4A shows a case where one mobile device 10 used by one user occupies a predetermined communication band (for example, a band of 384 kbps). FIG. 4B shows a case where the mobile device 10 used by the user A and the mobile device 10 used by the user B share a predetermined communication band.

  The lower the degree of sharing the communication band, the faster the communication speed. In addition, even when the degree of sharing the communication band is the same, the communication speed is slow when the network is congested. Thus, it can be said that the communication class represents a relative communication speed, not information indicating a fixed communication speed. Hereinafter, a communication class having a small degree of sharing the communication band is referred to as an “upper communication class”, and a communication class having a large degree of sharing the communication band is referred to as a “lower communication class”.

  For example, the content-compatible communication control condition storage unit 11 takes a long time to download content from the content provider 40 to the mobile device 10 for content types with a relatively large amount of data such as moving images, images, and audio files. The upper communication class or the high speed is stored in association with each other so that it is not necessary. On the other hand, for a content type with a relatively small amount of data such as a normal web page, a lower communication class or a slow speed is stored in association with each other.

Returning to FIG. 2, the guaranteed speed storage unit 12 is provided in the communication determination device 30 and stores the guaranteed communication speed according to the type of content. FIG. 5 shows an example of data stored in the guaranteed speed storage unit 12. As shown in the figure, the guaranteed speed storage unit 12 stores a content type and a communication guaranteed speed in association with each other.
Returning to FIG. 2, the communication control condition determination unit 13 is provided in the communication determination device 30. When communication between the mobile device 10 and the content provider 40 is started or when a content download request is generated, communication of the communication is determined. Determine the control conditions.

  Specifically, the communication control condition determination unit 13 sends a content request message for requesting content from the mobile device 10 (HTTP request, reception request for a web page, etc., and a download request for moving images, images, sounds, etc.). When the HTTP response is received from the content provider 40, the content type requested from the mobile device 10 is determined based on the header information of the HTTP response. Then, the communication control condition determining unit 13 searches and acquires the communication class or communication speed corresponding to the determined content type from the content corresponding communication control condition storage unit 11. Then, the communication control condition determination unit 13 determines the acquired communication class or communication speed as the communication control condition. Note that the above-described method for determining the content type based on the header information of the HTTP response is merely an example. For example, if possible, the content type is determined based on information included in the message transmitted from the mobile device 10. You may judge.

  The communication control unit 14 is provided in the communication control device 20, and controls communication between the mobile device 10 and the content provider 40 based on the communication control condition determined by the communication control condition determination unit 13. At this time, only the uplink, only the downlink, or both communication lines may be controlled, or communication in only a part of the section between the mobile device 10 and the content provider 40 may be controlled. The entire section may be controlled.

  Further, the communication control unit 14 controls the communication speed so as to guarantee the communication guaranteed speed stored in the guaranteed speed storage unit 12. Specifically, the communication control unit 14 performs control so that the communication speed becomes the communication guaranteed speed stored in the guaranteed speed storage unit 12 when the current traffic amount is a predetermined amount or more. Further, when the current traffic volume is less than the predetermined volume, control is performed so that the communication speed is high (speed higher than the communication guarantee speed).

Next, the operation of the communication control system 1 in the above configuration will be described with reference to FIG.
First, the user operates the mobile device 10 to request acquisition of desired content.
Thereby, the mobile device 10 transmits an HTTP request for requesting content (step S1).
When the content provider 40 receives the HTTP request, the content provider 40 acquires the requested content from the database. The content provider 40 generates an HTTP response including the acquired content and describing the content type in the header. The content provider 40 returns the generated HTTP response (step S2).

The communication control condition determination unit 13 of the communication determination device 30 determines the content type based on information described in the HTTP response header received from the content provider 40. The communication control condition determination unit 13 searches the content correspondence communication control condition storage unit 11 for a communication control condition corresponding to the determined content type (step S3). The communication determination device 30 transmits the searched communication control condition to the communication control device 20 (step S4).

FIG. 12B shows information indicating the correspondence between the connection destination and the charge rate. FIG. 12C shows information indicating the correspondence between the application type and the charge rate.

Returning to FIG. 8, the priority storage unit 24 stores the priority between the charge rates. The priority between the charge rates is used when determining one charge rate from among the charge rate candidates when there are a plurality of charge rate candidates.
When a connection request message is transmitted from the mobile device 110 to the connection destination device, the communication control condition determining unit 25 includes information related to the mobile device 110 and information stored in the charge rate determining information storage unit 23. The charge rate is determined based on

Here, the information related to the mobile device 110 includes the contract contents of the communication service to which the mobile device 110 is subscribed, the identification information of the connection destination device, and the communication application type. FIG. 13A is a diagram illustrating a state in which the charge rate is calculated based on the contract contents, the connection destination, and the application type.
In addition, the communication control condition determining unit 25 determines the rate based on the information stored in the rate rate determining information storage unit 23. When there are a plurality of rate rate candidates, the priority level storage unit The charge rate with the highest priority is selected with reference to the information stored in 24.

Consider the case where it is remembered. In addition, it is assumed that “rate A> rate B> rate C” is stored in the priority storage unit 24 as the priority between the charge rates. Further, it is assumed that the charge-related communication control condition storage unit 22 stores higher-order communication classes in association with charge rates in the order of rate A> rate B> rate C.

In the charge rate determination information storage unit 23, when the “charge rate” corresponding to the “connection destination” of the mobile device 110 is the rate A (step S11), the rate B and the “connection destination” corresponding to the “contract contents”. The priority with the rate A corresponding to is compared, and since the priority of the rate A is higher, the rate A is selected.
On the other hand, if the “fee rate” corresponding to the mobile device 110 “destination” is as contracted or is the rate B or C (step S12), the priority between these rates and the rate B corresponding to the “contracted content” The rate B is compared, and the rate B having the higher priority is selected.

Next, when the rate B is selected in the comparison between the “contract contents” and the “connection destination”, the rate B and the rate corresponding to the “application type” are compared.
When the “fee rate” corresponding to the “application type” is the rate A (step S13), the priority between the currently selected rate B and the rate A corresponding to the “application type” is compared, and the priority is high. Select rate A.

May be. The same applies to the device configuration of the communication control system 2 according to the second embodiment.

  In the above-described embodiment, the user is described as connecting to the connection destination device such as the content provider 40 using the mobile devices 10 and 110. However, the user terminal used by the user is limited to the mobile devices 10 and 110. For example, the user terminal may be a personal computer. Communication controlled by the communication control systems 1 and 2 is not limited to packet communication, and includes any communication such as voice communication.

  Further, the communication control condition determination units 13 and 25 determine the degree of sharing the communication band (communication class) or determine a fixed communication speed according to various conditions in order to flexibly cope with the network situation. It may be possible to select either. For example, a communication class may be selected when the traffic volume is large, and a fixed communication speed may be selected when the traffic volume is small. Further, the fixed communication speed may be determined only in the case of communication between a specific mobile device 10 and a specific content provider 40.
