[0022]

Embodiments of the present invention will be described below. The contents described in this embodiment are as follows.
This is an explanation of an optimum communication position selection method in the wireless communication system of the present invention, and specific processing contents of the optimum communication position selection processing program in a recording medium recording the optimum communication position selection processing program in the wireless communication system of the present invention. Is also included.

In this embodiment, an example in which the present invention is applied to a communication system using a wireless LAN will be described.

FIG. 1 shows a schematic configuration of a communication system for explaining an embodiment of the present invention, in which an access point 1 as a first information processing device connected to a wired communication transmission line 3 and an access point 1 1 is composed of a user terminal 2 as a second information processing device capable of performing wireless communication.

As shown in FIG. 2, the access point 2 has a radio signal transmitting / receiving unit 11, a wired signal transmitting / receiving unit 12, a signal processing unit 13, a communication quality measurement data generating unit 14, and the like. In addition, there are various other components necessary for performing the operation as the access point,
Here, only components necessary for describing the present invention are shown, and illustration and description of other components are omitted.

On the other hand, the user terminal 2 is an information processing device such as a personal computer used by the user, and has a radio signal transmitting / receiving unit 21, a signal processing unit 22, an optimum communication position selecting unit 23, and the like. In addition, there are various other components necessary for performing the operation as the user terminal, but here, only the components necessary for describing the present invention are illustrated,
Illustration and description of other components are omitted.

The optimum communication position selecting unit 23 provided in the user terminal 2 includes a communication quality measuring unit 24, a storage unit 25 for storing various data such as a communication quality measurement result, and a communication quality evaluation result to the user. And a communication quality evaluation result output unit 26 that outputs the result as a message.

Next, a specific operation in such a configuration will be described. First, a case will be described in which an information processing device whose installation place is limited to some extent, such as a desktop personal computer (hereinafter, simply referred to as a personal computer), is used as the user terminal 2.

This type of information processing apparatus is usually semi-fixedly installed on a desk or table, and it is assumed that several installation locations can be selected.

In this embodiment, as shown in FIG.
It is assumed that there are three desks A1, A2, and A3, which are sequentially installed at the respective desks, and which desk is installed to obtain the best communication quality. In addition, desk A1
P1 is the installation location at desk and P is the installation location at desk A2.
2. The installation location on the desk A3 is P3. In addition, each installation location P1, of each desk A1, A2, A3
When installed in P2 and P3, the communication quality differs depending on the orientation of the installed personal computer. However, here, in order to make the explanation easy to understand, the case where only the installation location is considered will be described, and the orientation will be considered. We will touch on the case later.

First, the personal computer which is the user terminal 2 is connected to the desk A
1 is set at the position P1 above, and test communication is performed in that state. At this time, the user inputs P1 as the position information and gives an instruction to start the test. As a result, a test signal for measuring communication quality is created by the signal processing unit 22, and the test signal is transmitted from the wireless signal transmission / reception unit 21. Then, when the access point 1 receives it, the access point 1
Then, the communication quality measurement data is generated by the communication quality measurement data generation unit 14, and the communication quality measurement data is transmitted from the wireless signal transmission / reception unit 11.

When the radio signal transmitting / receiving section 21 of the user terminal 2 receives the data for measuring communication quality from the access point 1, the received data is transferred to the communication quality measuring section 23 according to an instruction of the signal processing section 22.

Thus, the communication quality measuring section 24 calculates an error rate or the like for the received data and outputs it as a measured communication quality value. This communication quality measurement is
It is stored in the storage unit 25 in association with the position information at that time (P1 in this case).

Next, the user terminal 2 is installed at the position P2 on the desk A2, and a test communication is performed in this state. At this time, the user inputs P2 as position information,
Give instructions to start the test. As a result, a test signal for measuring communication quality is created by the signal processing unit 22, and the test signal is transmitted from the wireless signal transmission / reception unit 21. Then, when the access point 1 receives it, the access point 1 transmits the communication quality measurement data generated by the communication quality measurement data generation unit 14.

When the wireless transmission / reception unit 21 of the user terminal 2 receives the communication quality measurement data from the access point 1, the received signal is transferred to the communication quality measurement unit 23 according to an instruction of the signal processing unit 22.

Thus, the communication quality measuring section 24 calculates an error rate or the like for the received signal and outputs it as a measured communication quality value. This communication quality measurement value is stored in the storage unit 25 associated with the position information (P2 in this case) at that time.

Next, the user terminal 2 is set at the position P3 on the desk A3, and the same processing is performed.

FIG. 4 shows the communication quality evaluation results obtained in this manner. The horizontal axis indicates the installation position of the personal computer as the user terminal 2 (the respective positions P1, P2 on the desks A1, A2, A3). , P3), and the vertical axis indicates the communication quality measurement unit 2
4 is the communication quality measurement value y1. y2 and y3 are shown. Here, it is assumed that the larger the measured communication quality value, the better the communication quality.

In the example of FIG. 4, the communication quality y2 when installed on the desk A2 is larger than the other communication qualities y1 and y3, and the desk A2 is among the three desks A1, A2 and A3. It can be seen that the best communication can be performed when the communication device is installed in a location.

In order to obtain such a result, as a user operation, first, a place to be set is selected. For example, the user terminal 2 is placed on the desk A1 to start trial communication. At this time, P1 is input to the user terminal 2 as position information to perform trial communication. Similarly,
The other desks A2 and A3 also have respective location information P2 and
The test communication is performed by inputting P3.

By performing such an operation by the user, the communication quality evaluation result output unit 26 outputs the desks A1, A
The communication quality measurement values for the respective positions P1, P2, and P3 of A2 and A3 are output and displayed on the display screen of the user terminal 2 as communication quality evaluation results.

The display method is as follows.
The communication quality measurement values for P2 and P3 are displayed in the form of a list, displayed in a graph format as shown in FIG. 4, and displayed to the user not only on the display screen but also by voice. It can be presented and various other possibilities are possible, but the manner of display is not limited.

In the above description, the desks to be installed are selected from several desks previously installed at the respective locations, and the user terminals 2 are sequentially installed to perform trial communication. In this example, communication quality evaluations at each desk were obtained. However, the present invention is not limited to this example. To obtain the communication quality evaluation at each position. For example, as shown in FIG. 5, taking the desk A2 as an example, the installation positions on the desk A2 are selected as P21, P22, and P23, and the user terminals 2 are sequentially installed at the respective positions. By performing the same test communication, the respective positions P21, P21
The communication quality may be measured in steps 22 and 23, and the result may be presented to the user.

In this case, in order to make the position clear after the communication quality result is obtained, a unique number or the like is attached to each installation position (this is an installation position indication seal in this case). One method is to put a label such as "). That is, first, P21
At this position, an installation position indicating sticker written as “p21” is attached, the user terminal 2 is installed, and test communication similar to that described above is performed. When that is completed, this time, "p"
The operation of attaching the installation position indicating sticker “22”, installing the user terminal 2, and performing the test communication similar to that described above is repeated.

Thus, for example, if it is found that the best communication quality can be obtained when the terminal is installed at the position of P22, the user terminal 2 is placed on the sticker attached at the position of P21.
Should be installed. As described above, it is needless to say that the operation of attaching the installation position indicating sticker indicating the installation position can also be applied to the case of FIG. 3 described above, and in the example of FIG. This is convenient because the relationship between each desk and its communication quality data can be clearly understood later by the installation position indicating sticker, for example, when performing trial communication by changing the number of times.

Also, in the description with reference to FIG. 3, the desk A2 can obtain better communication quality than the other desks A1 and A3, but the operation shown in FIG. 5 is performed on the desk A2. Thereby, a position where better communication quality can be obtained can be found.

Further, in the above description, the direction of the user terminal 2 at each installation position is not described, but when performing communication quality measurement, the direction of the user terminal 2 is changed at each installation position. The communication quality can be measured for each direction.
This will be described with reference to FIG.

FIG. 6 shows P2 in desk A2 shown in FIG.
The user terminal 2 is installed at the position of. In this example, the direction of the device is set to each of the arrows Q1, Q2, and Q3. In this case, even after the communication quality measurement result is obtained, a sticker indicating each direction (for example, a sticker with an arrow or a unique number, etc. is drawn here) so that the direction can be recognized. It is also a good idea to stick a direction indicator sticker).
There are two ways.

That is, first, a direction indicating sticker indicating the direction of Q1 is attached to the position of P2, and the user terminal 2
Is set up, and a test communication similar to that described above is performed. When this is completed, a direction indicating sticker indicating the direction of Q2 is affixed, the user terminal 2 is installed, and test communication similar to the above is performed. When this is completed, a direction indicating sticker indicating the direction of Q3 is pasted, the user terminal 2 is installed, and a test communication similar to the above is performed.

As described above, when the communication quality is obtained for each device orientation at a certain position, the result presented to the user is based on the communication quality results obtained at each position and each direction at that position. Present as a result.

Thus, for example, if it is found that the best communication quality can be obtained when the user terminal 2 is installed at the position of P1 and the direction is set at the direction of Q1, the user terminal 2 is put at the position of P1. The personal computer may be installed in the direction according to the direction indicating sticker indicating the direction of Q1.

The above is a case where the installation location of the user terminal 2 is limited to a certain extent, such as a desktop personal computer. A case where a high information processing device is used will be described.

In the case of this notebook personal computer, it is the same as that of the desktop personal computer that the communication quality is determined by conducting trial communication. However, in the case of this notebook personal computer, since the portable personal computer is free to carry, the communication quality is reduced. It can be obtained continuously. This will be described below.

FIG. 7 is a diagram for explaining an example in which the communication quality with respect to the access point is obtained while moving the notebook personal computer (user terminal 2) in the direction of arrow R. In this case, the communication quality is continuously obtained, but the operation for obtaining the communication quality is performed at regular time intervals. That is, as described above, in the series of processes for obtaining the test communication quality, a signal for performing a test is transmitted from the user terminal 2 to the access point 1, and a response signal corresponding to the signal is transmitted from the access point 1 to the user terminal. 2 is a process from reception to calculation of an error rate and the like for the received signal to output a communication quality measurement result.

Therefore, the communication quality at each location is output for each time necessary for performing this series of processing. It should be noted that, after obtaining the communication quality for one time, the next communication quality may be obtained a little after a while, but the case where the communication quality is obtained continuously will be described here.

Now, the user has a notebook personal computer as the user terminal 2, starts from the position R1, moves to the position Rn, and continuously seeks communication quality during that time.

FIG. 8 shows a communication quality evaluation result obtained by continuously measuring the communication quality while the user moves along the arrow R in FIG. 8 shows the user's movement position on the horizontal axis and the communication quality measurement value obtained by the communication quality measurement unit 24 on the vertical axis. As can be seen from FIG. 9, the communication quality measurement value There are several maxima. In the example of FIG. 8, the maximum values C1, C2. C3, C
There are four. When the communication quality measuring unit 24 obtains the local maximum value, the communication quality evaluation result output unit 26 notifies the user that the local maximum value has been obtained by some means at that time, and the communication quality measurement value The maximum value is stored in the storage unit 25.

When storing the maximum value in the storage means 25,
The maximum value is stored with some kind of heading. The heading may be simply a number, for example, NO.1, NO.
2,... Are prepared, and the numbers and the maximum values at that time are stored in association with each other. As a method of notifying the user that the maximum value has been obtained, for example,
The maximum value may be displayed on the display screen in association with the index number, or the maximum value may be notified by voice or the like in association with the index number, and the method is particularly limited. is not.

When the user is notified that the maximum value has been reached, a sticker indicating the heading number (referred to as a heading number sticker) is put on that location. For example, FIG.
Assuming that the position where the maximum value C1 is obtained is the position of R2, a heading number sticker of No. 1 is attached to the position of R2, and the position where the maximum value C2 is obtained is the position of R3. Each time a maximum value is obtained, a label indicating a number is pasted at that position, such as putting a heading number sticker of No. 2 at the position of R3.

Then, a certain moving range (R in FIG. 7)
When the movement in (from 1 to Rn) is completed, a value indicating the maximum communication quality obtained so far is listed up and presented to the user. This presentation method may be shown in the form of a graph as shown in FIG. 8, or in the form of a list in which a heading number is associated with a local maximum value. The display method is not particularly limited. is not. When this display is performed, the display of the maximum value portion may be performed so that it can be distinguished at a glance from the other maximum point portions (for example, the color is changed).

The user confirms the position where the best communication quality can be obtained by the display. For example, in this case,
As can be seen from FIG. 8, since the maximum value C3 is the maximum value in this section, the index number (N
It can be said that the position of O.3) provides the best communication quality. Therefore, if communication is performed at the position where the sticker of No. 3 is attached, it is highly likely that the best communication quality can be obtained.

When the user terminal 2 is a portable information processing device such as a notebook computer, not only the position but also the
By changing the direction at each position, it is also possible to specify the direction that provides the best communication quality. For example, by measuring the communication quality while changing the direction of the notebook PC at the position where the sticker of NO.3 is attached, some maximum values may be obtained. Then, if the direction in which the maximum communication quality measurement value is found among some local maximum values is found and communication is performed in that direction, communication with better communication quality can be performed.

The present invention is not limited to the above-described embodiments, but can be variously modified without departing from the gist of the present invention. For example, while the communication device (access point) that is the communication partner of the communication device owned by the user has been described as being one in the above description, the present invention is also applied to the case where a plurality of access points exist. be able to. For example, as shown in FIG. 9, a plurality of access points 1a,
Of course, the present invention can be applied to the case where 1b, 1c,. In this case, for each of the access points 1a, 1b, 1c,..., The communication quality data for the installation location and orientation described above is obtained, and for each of the access points 1a, 1b, 1c,. ,
The communication quality evaluation result corresponding to the installation position and orientation is presented to the user.

The above description has been made on the assumption that communication is performed with an access point. However, the present invention is not limited to this, and wireless communication between general information processing devices is not limited to this. It can be adapted to the case where it is performed. Furthermore, in the above-described embodiment, an example has been described in which a sticker is attached to specify the position and the direction of the user terminal 2. However, the present invention is not limited to this, and the position may be specified by another method. You may.

Further, the processing program for performing the optimum communication position selection processing of the present invention described above can be recorded on a recording medium such as a floppy disk, an optical disk, or a hard disk, and the present invention includes the recording medium. It is a thing. Further, the processing program may be obtained from a network.

[0066]

As described above, according to the present invention, for example, a user uses an information processing device (second information processing device) such as a personal computer to access an access point (second information processing device). In such a case where communication is performed between the user and the user, it is possible to easily know which location or orientation should be set to obtain good communication quality. In particular, in the present invention, each installation location and each orientation The communication quality evaluation result can be presented to the user in association with the user, so that it is clearly understood which location (direction) has poor communication quality and which location (direction) has good communication quality, and a mark is attached to each location and direction. If this is done, an information processing device such as a personal computer can be installed in a place (orientation) where optimal communication quality is possible, thereby enabling communication in a good communication state.
