Description

  The present invention relates to a mobile radio communication apparatus having a function of relaying radio communication.

  A technique for connecting a wireless device having a wireless slave function such as a mobile phone or a game machine to a wireless master device such as an access point by wireless LAN (Local Area Network) communication is widely used.

  As a wireless LAN communication standard, there is IEEE802.11 defined by IEEE (The Institute of Electrical and Electronics Engineers, Inc.).

  The frequency bands used by IEEE802.11 are roughly divided into 2.4G band and 5G band.

  Further, the 5G band is classified into 36ch to 48ch (hereinafter referred to as W52 band), 52ch to 64ch (hereinafter referred to as W53 band), and 100ch to 140ch (hereinafter referred to as W56 band).

  The W52 band and W53 band frequencies described above are also used in public systems other than wireless LANs, and radio waves from wireless LANs and public systems may interfere with each other. .

  For this reason, depending on whether the place of use is indoors or outdoors, the user needs to check the wireless connection frequency. Depending on the place of use, the user needs to change the connection frequency setting. .

  In Patent Document 1, a wireless communication device receives a base station identification code transmitted from an access point that is a connection destination of a wireless LAN, and the wireless communication device uses a base station identification code based on whether the use place is installed indoors or outdoors. Determine if it is an installation.

  In Patent Document 1, a satellite positioning system (GPS: Global Positioning System) is mounted on a wireless communication device, and the wireless communication device obtains position information of the wireless communication device, so that the use location is outdoor or indoor. It is also shown to determine.

  In Patent Document 2, a wireless communication device receives a reflected wave of a radio wave emitted from the wireless communication device itself, obtains a distance between the wireless communication device and a reflecting object from a propagation time of the reflected wave, and determines a wall surface, a ceiling, or a floor surface. It is estimated whether it is indoor or outdoor.

International Publication No.2012 / 137908 JP 2003-283509 A

  In Patent Document 1, when a wireless communication device is connected to a base station whose base station information is not registered in the wireless communication device, a method for determining whether the wireless communication device is located indoors or outdoors is an electric field strength determination. Therefore, the method of Patent Document 1 is ambiguous.

  The same patent document 1 also shows a case where the position of the wireless communication device is specified by GPS information and it is determined whether the wireless communication device is indoors or outdoors, but only a positioning error of several meters occurs in the GPS information. Thus, the wireless communication device makes a determination error.

  In addition, the addition of the GPS function increases the size of the wireless communication device and increases power consumption. Therefore, the GPS function is added to mobile terminals that are required to be downsized like mobile routers and have limited battery capacity. Is not suitable.

  Since the method of Patent Document 2 needs to include radio wave transmission means and reflected wave reception means in order to determine the position of the radio communication device, the radio communication device becomes complicated and large-sized, like a mobile router. However, it is not suitable for those that require miniaturization.

  In order to solve the above-described problems, the present invention provides a wireless communication apparatus, a communication method, and software for relaying wireless communication by selecting an appropriate frequency band with a small and simple configuration suitable for a portable type. The purpose is to provide.

A first device of the present invention includes a first wireless communication unit that communicates with a connection destination using a first wireless signal according to predetermined communication conditions;
A second wireless communication unit that communicates with a second wireless signal;
A communication method determination unit that determines what is possible as the communication condition and outputs the determination result;
A restriction unit restriction unit that instructs the second wireless communication unit to permit or deny use of a predetermined frequency band based on a predetermined acceptance criterion including the determination result.

  According to the present invention, a portable wireless communication device having a relay function, called a mobile router or the like, can select and communicate with an appropriate frequency band with a small and simple configuration suitable for a portable type.
