Problems solved by technology

The reality, however, is that a useful technique for using the only port on an access point as both an external network-side port and an internal network-side port has not been possible until now
[0004] Furthermore, such a technical problem of course also exists in an access point with multiple ports, when each port is considered individually, there will be cases where the port is used both as a port on the external network side and as a port on the internal network side
Moreover, such a technical problem does not only exist in the wireless relay device used as a LAN access point, it is a common technical problem in any wireless relay device performing wireless communication in a wireless communication network

no. 2 Embodiment

[0080] In the above-mentioned first embodiment, the premise is that the main body 100 and the bracket 200 are connected. In this second embodiment, a connection mode in which the station STA can be connected to the Internet even when the main body 100 is not connected to the cradle 200 will be described. Figure 14 It is a flowchart showing the operation mode switching processing procedure of the second embodiment performed by the wireless relay device 10 .

[0081] Such as Figure 14 As shown, the difference between the operation mode switching process of the second embodiment is that the operation mode switching process of the above-mentioned first embodiment ( Figure 5 ) adds the following step (step S130), that is, when the main body 100 starts, when the main body 100 is not connected to the stand 200 (step S105, No), the transmission control unit 122 switches the operation mode of the transmission processing unit 121 to the third action mode. This switching to the thi...

Deformed example 1

[0091] The configuration of the wireless relay device 10 in the above-described embodiments is merely an example, and various modifications are possible. For example, in the above-mentioned embodiment, the stand connection interface 180 of the main body 100 and the main body connection interface 280 of the stand 200 are used to exchange information based on the USB standard, but the exchange of information between the main body 100 and the stand 200 can also be based on USB Specifications other than specifications. In this case, instead of the USB device interface 173, the main body 100 may be provided with an interface based on another standard.

Deformed example 2

[0093] In addition, in the above-described embodiment, the wireless LAN control circuit 174 or the wireless WAN control circuit 175 may perform wireless communication based on the wireless LAN standard that can be used in the future instead of performing communication based on the IEEE802.11a / b / g / n standard. Wireless communication. In addition, the mobile communication control circuit 176 can also perform wireless communication based on mobile communication standards that can be used in the future, such as LTE, next-generation wireless WiMAX (IEEE802.16m), and next-generation PHS (XGP: eXtended Global Platform). Instead of mobile communications based on 3G / HSPA specifications.

Abstract

The invention provides a wireless relay device communicable with an internal network to which one or more stations belong and with an external network to which the stations do not belong. A switch switches between an external connection state where a port functions as an external-network-side port, and an internal connection state where the port functions as an internal-network-side port. A transfer process section transfers, when the switch is in the external connection state, a packet between a station belonging to a wirelessly connected internal network and a modem wiredly connected to the port, and otherwise transfers, when the switch is in the internal connection state, a packet between a station wiredly connected to the port and a network device belonging to a wirelessly connected external network.

Description

technical field [0001] The present invention relates to a wireless relay device for relay processing of communication in a wireless communication network. Background technique [0002] In homes or offices, in order to connect wireless or wired local area network (Local Area Network, LAN) stations such as personal computers and game consoles to other networks, access points (access points) as wireless relay devices (such as access points) are widely used. , with reference to Japanese Patent Publication No. 2005-142907). As such an access point, there has been proposed a portable access point capable of wirelessly connecting to a network at a location outside the home. [0003] In the portable access point, in order to realize the miniaturization of the casing, for example, most of the structures adopted only have one port for connecting a network cable. The user wishes that, in such an access point having only one port, the one port can be used as a port (a port on the exte...
