Description

  The present invention relates to a wireless communication apparatus having a plurality of wireless communication means for accessing a communication network and switching wireless communication means to be used according to a state, and a communication system having the wireless communication apparatus.

  By having multiple wireless communication means conforming to various wireless communication standards and switching the wireless communication means to be used according to the situation, for example, communication by wireless LAN (Local Area Network) and communication by mobile communication network are used properly Wireless communication devices have been commercialized (for example, see Non-Patent Document 1).

  In the wireless communication device described in Non-Patent Document 1, a single mode or a dual mode is selected as a use mode. In the dual mode, the wireless communication means to be used, such as a mobile communication network or a wireless LAN, is given priority, and when both wireless communication means are usable, communication is performed by the wireless communication means having a high priority. In the dual mode, it is necessary to supply power to a plurality of wireless communication means for monitoring the communication status. However, the power consumption can be reduced by using a technique such as intermittent reception of the wireless LAN. Is going.

  When using these wireless communication apparatuses having a plurality of wireless communication means, the method of selecting communication means becomes a problem on the wireless communication apparatus side. In particular, when the service area of one system is limited, such as a mobile communication network and a wireless LAN, both communication means cannot always be used. At the moment when the means becomes available, there is a possibility that a switch unexpected by the user may occur.

  In addition, as a method of using a plurality of wireless communication means, for example, wireless communication devices that can be connected to a wireless LAN and a mobile communication network, for example, at home, a CATV (Cable Television) or ADSL (Asymmetric Digital Subscriber Line) line is used. It is conceivable to install a wireless LAN access point device, connect to a communication network via a wireless LAN via the access point device, and connect to a mobile communication network for communication when going out. It is necessary for another person to use the installed access point device to connect to the communication network, that is, to restrict access from unauthorized wireless communication devices.

  As a method for selecting communication means, Non-Patent Document 2 describes a method in which a threshold is set for the received power intensity of a wireless LAN and the wireless communication means is switched based on the received power intensity.

  As a method for restricting access from unauthorized wireless communication devices, an IC card that records a usable communication system is attached to the wireless communication device, and the wireless communication device itself recognizes an available communication system and accesses it. A configuration for performing the restriction is described in Patent Document 1.

For example, even if the user wishes to communicate via a mobile communication network with good sound quality in order to have an important conversation, if the received power intensity of the wireless LAN exceeds a threshold due to movement, the wireless LAN It will be switched to communication.

  Furthermore, since it is necessary to always supply power to a plurality of wireless communication means, there is a disadvantage that power consumption increases. In Non-Patent Document 1, power consumption is reduced by performing intermittent reception in a wireless LAN. However, power is intermittently supplied to wireless communication means for the wireless LAN.

  As already described, the wireless communication device 1 includes the interface units 11 and 12. In the following description, it is assumed that the interface unit 11 is a communication unit for connecting to a mobile communication network, and the interface unit 12 is a communication unit for connecting to a wireless LAN. Therefore, the user does not need to worry about the location of the base station (not shown) for connection using the interface unit 11, and the communication unit 17 of the wireless communication device 1 sets the initial value as the initial value. It is assumed that the interface unit 11 is selected.

  The access point device 2 is a wireless LAN access point, and is connected to the communication network 5 via the HUB 4. Accordingly, the wireless communication device 1 can be connected to the communication network 5 via the access point device 2 by the interface unit 12. FIG. 4 is a configuration diagram of a communication system according to the present invention, and shows a state in which the wireless communication device 1 is communicating via the access point device 2.

  The set-top box 3 is installed for each access point device, has a communication unit capable of communicating with the communication unit 17 of the wireless communication device 1, and further, a terminal identifier of the wireless communication device permitted to be used and a corresponding access point In the example of FIG. 3, the identifier of the access point device 2 is included. In the following description, it is assumed that the set top box 3 has the terminal identifier of the wireless communication device 1 as a wireless communication device that is permitted to be used.

  Hereinafter, as shown in FIG. 3, the wireless communication device 1 communicating with the communication terminal 6 by the interface unit 11 moves within the communication range of the access point device 2, and then communicates via the access point device 2. An explanation will be given taking the case of switching to.

  First, even if the wireless communication device 1 moves within the communication range of the access point device 2 due to the movement of the user, the interface unit 12 is not even supplied with power. 11, communication is performed, and switching does not occur.

  In order for the user to switch to communication via the access point device 2, that is, communication by wireless LAN, the set-top box 3 installed in the communication area of the access point device 2 is connected to the wireless communication device 1. The communication is performed between the communication unit 17 of the wireless communication device 1 and the communication unit of the set top box 3.

  FIG. 5 is a switching sequence diagram from FIG. 3 to FIG. 4, that is, switching from communication via the mobile communication network by the interface unit 11 of the wireless communication apparatus 1 to communication via the wireless LAN by the interface unit 12. . The set top box 3 acquires information about the terminal identifier and the interface used from the communication unit of the wireless communication device. The set-top box 3 performs authentication by comparing the acquired terminal identifier with the terminal identifier of the wireless communication apparatus that is permitted to be used.

  If the authentication is successful, whether to switch from the acquired interface information currently used by the wireless communication device 1 to the switching direction, that is, the communication via the access point device 2 that is the corresponding access point, or access It is determined whether to switch from communication via the point device 2 to communication via another interface. Subsequently, the switching notification including the switching direction is made to the communication network 5 together with the terminal identifier and the identifier of the access point device 2. At the same time, the wireless communication device 1 is also notified of switching, and the communication unit 17 of the wireless communication device 1 notifies the control unit 16 of the switching.

  The communication network 5 that has received the switching notification changes the transmission path of the signal to the wireless communication device 1 and passes through the notified access point device 2. Also in the wireless communication device 1, as described above, power is supplied to the interface unit 12, and after confirming communication via the access point device 2, power supply to the interface unit 11 is stopped.

  Similarly, when the user wants to switch from communication via the access point device 2 to communication via the mobile communication network, the wireless communication device 1 is similarly placed in the communication area of the access point device 2 currently used. The communication unit 17 of the wireless communication apparatus and the communication unit of the set top box 3 are communicated with each other close to the set top box 3 installed. The set-top box 3 notifies the communication network 5 of the terminal identifier, the identifier of the access point device 2, and the switching notification including the switching direction. The communication network 5 that has received the switching notification transmits the signal to the wireless communication device 1. The route is changed, and the change is made from the notified access point device 2 to the mobile communication network. In this case, authentication with a set top box is not essential.

  FIG. 6 is a switching sequence diagram in another embodiment of the communication system according to the present invention. In the switching sequence diagram shown in FIG. 5, the set-top box 3 notifies the communication network 5 and the wireless communication device 1 after the authentication, but in this embodiment, the set-top box 3 is authenticated successfully. In this case, the wireless communication device 1 is notified of the identifier of the access point device 2, and the wireless communication device 1 notifies the communication network 5 of switching.

The interface to be used is switched by using the communication unit 17 of the wireless communication apparatus 1 as a trigger to communicate with an external communication unit. However, when there is a difference in the service area, such as switching between a mobile communication network and a wireless LAN, when using communication means in a narrow service area, the service area is unexpectedly exited. As a result, communication may be interrupted. For this reason, for example, when a local communication means such as a wireless LAN is used, the communication status monitoring unit 161 of the control unit 16 monitors the radio wave status, and the radio wave status deteriorates. The interface switching unit 162 is preferably switched to a communication means having a wide service area, such as a mobile communication network. In this case, the control unit 16 notifies the communication network 5 of switching, and after switching, notifies the communication unit 17 of the interface to be used.

  In the above description, the set top box 3 is assumed to be an independent device. However, the functions of the set top box 3 can be implemented in other devices such as the access point device 2, for example. .
