Description

The invention described in this specification relates to a technique for optimizing wireless communication standard information in an electronic device having a function of communicating with a wireless network in accordance with a country of use or a region.
The invention has aspects as an electronic device, a wireless communication standard information setting device, a wireless communication standard information setting method, and a computer program.

  In recent years, in the field of wireless communication, the UWB (Ultra Wideband) wireless communication system is spreading as one of the leading communication systems. The UWB wireless communication system has a history of opening what was originally developed for military purposes in the United States to the private sector.

  In other wireless communication systems, the frequency bandwidth of one channel is about several tens of MHz, whereas in the UWB wireless communication system, a frequency bandwidth of 3.1 [GHz] to 10.6 [GHz] is used. . For this reason, the UWB wireless communication system can transmit a large amount of data at high speed.

  By the way, the UWB wireless communication system has a feature that the radiation power level in the frequency band is very low and there is no interference with other systems. In addition, the UWB wireless communication system has a feature of low power consumption.

From these features, the UWB wireless communication system is used for sensors using a position measurement function, radar using an object detection function, wireless communication between electronic devices, and the like.
By the way, the radio wave conditions in various parts of the world vary greatly. Actually, different wireless communication standards (for example, used frequency band, power mask) are defined for each country or region.

For this reason, even when a wireless network is constructed using the same wireless communication system, a situation in which different frequency bands and power masks are used for each country or region often occurs.
For example, in the case of a UWB (Ultra Wideband) wireless communication system, different wireless communication standards are being developed in Japan, the United States, and Europe.

  In other words, different power masks are being adopted for each region (as of 2006). For this reason, at present, the user himself / herself needs to change the setting of the wireless communication standard every time an electronic device equipped with a UWB wireless communication function exceeds a region or country. However, in practice, there is no guarantee that the user will change the setting of the wireless communication standard.

  In order to solve such a situation, early international harmonization regarding the UWB wireless communication system is desired. However, illegal radio waves cannot be left until international harmonization is achieved. On the other hand, it is too harsh to attribute illegal radio wave conditions to the user.

Therefore, Patent Document 1 discloses a mechanism for automatically selecting a wireless communication standard suitable for a use region by installing a GPS receiver in each wireless device.
Japanese Patent Laid-Open No. 9-43338

Also, in Patent Document 2, a GPS receiver is mounted on one of the radios that construct a radio network, the use area is specified, and frequency information that can be used in the specified use area is automatically transmitted to other radio units. A mechanism to notify automatically is disclosed.
JP 2002-159043 A

However, in the case of the mechanism disclosed in Patent Document 1, it is necessary to mount GPS receivers on all the wireless devices that construct the wireless network, which increases the cost of the wireless devices.
On the other hand, in the case of the mechanism disclosed in Patent Document 2, only one wireless device is installed in the wireless network, but a direct connection between the wireless device equipped with the GPS receiver and each wireless device is possible. Communication is essential.

  In view of this, the inventor wirelessly transmits the wireless communication standard information acquired by the device itself to the electronic device equipped with the wireless network communication function, the standard information acquisition unit that acquires the wireless communication standard information defined for the wireless network. A standard information setting unit for notifying at least one other electronic device of a connectable wireless network through network communication is mounted.

  In addition, when the inventor receives a notification of wireless communication standard information from another device connected to the wireless network to an electronic device equipped with a communication function with the wireless network, the inventor stores the wireless communication standard information and notification stored in the device. Equipped with a standard information setting unit that determines whether the received wireless communication standard information matches, and if both do not match, updates the wireless communication standard information stored in its own device to the notified wireless communication standard information To do.

  In addition, when the inventor is notified of location information from an other device connected to the wireless network to an electronic device equipped with a communication function with the wireless network, the inventor obtains the wireless communication standard information defined for the location. Determines whether the information acquisition unit and the wireless communication standard information stored in its own device match the acquired wireless communication standard information, and if both do not match, acquires the wireless communication standard information stored in its own device And a standard information setting unit that updates the wireless communication standard information.

  In the case of the invention proposed by the inventor, if there is one electronic device having a standard information acquisition unit on the wireless network, the acquired wireless communication standard information is automatically transmitted even to an electronic device that cannot directly communicate with the electronic device. Can be notified.

  That is, by repeating the transfer operation between electronic devices, the standard information acquisition unit can be notified to all electronic devices located on the wireless network. Thereby, the wireless communication standard information of the whole wireless network can be optimized.

Hereinafter, an example of an electronic apparatus according to the invention will be described.
In addition, the well-known or well-known technique of the said technical field is applied to the part which is not illustrated or described in particular in this specification.
Moreover, the form example demonstrated below is one form example of invention, Comprising: It is not limited to these.

(A) Example of power mask specification The UWB wireless communication system is the Institute of Institute of Electrical and Electronics Engineers (IEEE).
According to classification by Electronics Engineers, Inc., WPAN (Wireless Personal)
Aria Network).

  The transmission distance of the UWB wireless communication system is about 10 m. When the transmission distance is 1 m to 2 m, data can be transmitted at 480 Mbps (conforming to the report of March 24, 2006, Ministry of Internal Affairs and Communications). Due to this characteristic, the UWB wireless communication system is considered to be applied to a high-speed wireless transmission system.

FIG. 1 shows an example of a power mask applied in each country or region applied to the UWB wireless communication system. The horizontal axis is frequency (MHz), and the vertical axis is power level (dBm / MHz).
The dashed line is the Federal Communications Commission (FCC)
Indicates a power mask released by the Communications Commission.

The alternate long and short dash line is the European Telecommunications Standards Institute (ETSI: European).
The provisional power mask (as of October 2005) created by Telecommunications Standards Institute) is shown. The solid line indicates a provisional power mask (as of March 2006) created by the Japanese Ministry of Internal Affairs and Communications.

Although it is still tentative for Europe and Japan, it can be seen from FIG. 1 that different power masks are assigned reflecting the radio wave conditions in each region.
In other regions, power masks are being developed to reflect the radio wave conditions in each region.

(B) Functional Configuration Example of Electronic Device (B-1) Functional Configuration of Electronic Device Mounting Power Mask Information Acquisition Unit FIG. 2 shows a functional configuration example of the electronic device 1 mounting the power mask information acquisition unit.

  The electronic device 1 includes a power mask information acquisition unit 3 and a power mask information setting unit 5 as a wireless communication standard information setting function. The power mask information acquisition unit 3 corresponds to the “standard information acquisition unit” in the claims, and the power mask information setting unit 5 corresponds to the “standard information setting unit” in the claims.

  In addition to the processing device corresponding to the power mask setting processing function, the electronic apparatus 1 is also equipped with a computer system, a storage medium, a UWB wireless communication device, a user interface, and the like that control the entire system.

  First, the processing function of the power mask information acquisition unit 3 will be described. The power mask information acquisition unit 3 detects the usage area of the electronic device and acquires the power mask information of the wireless network and other wireless communication standard information based on the detection result.

  FIG. 3 shows an internal configuration example of the power mask information acquisition unit 3. The processing function of the power mask information acquisition unit 3 mainly includes a location information acquisition unit 21, a country / region specifying unit 23, and a power mask selection unit 25.

  The location information acquisition unit 21 is a device that detects location information of the electronic device 1. For example, the location information acquisition unit 21 detects location information from a radio wave reception signal transmitted from a GPS (Global Positioning System) satellite 11. Also, for example, the location information acquisition unit 21 detects location information by receiving a beacon signal from an access point 13 having a GPS receiver.

  Note that the GPS receiver and the beacon receiver are not necessarily built in the electronic device 1 and may be externally connected. Further, if the location information can be detected, the system configuration is not limited to the GPS receiver or the beacon receiver. For example, location information may be detected using a mobile phone system, or may be acquired from an external server through the Internet.

  The country / region specifying unit 23 is a device that specifies the country or region where the electronic device 1 is located based on the detected location information. To specify the country or region, for example, a country code or a region code included in the location information is used. In addition, a country or a region can be specified by collation with map information. Here, the country / region specifying unit 23 does not need to hold the map information (may be held), but refers to the map information held by the external device.

  The power mask selection unit 25 is a device that refers to the reference table based on the specified country or region and selects power mask information corresponding to the country or region. The reference table here is stored in, for example, a nonvolatile storage medium. However, it is desirable to use a rewritable medium when dealing with rewriting of the reference table.

  In the reference table, power mask information is stored for each country or region. The power mask information selected by the power mask selection unit 25 is supplied to the power mask information setting unit 5.

  The power mask information setting unit 5 has a function of storing the acquired power mask information for wireless communication of the own device and notifying other electronic devices connected to the same UWB wireless communication network as the own device.

  After the initial setting of the power mask, the power mask information setting unit 5 determines whether or not the stored power mask information matches the newly acquired power mask information each time new power mask information is acquired. Determine whether.

  Here, when a match is detected, the power mask information setting unit 5 does not perform the process of updating the power mask information. On the other hand, when a mismatch is detected, the power mask information setting unit 5 executes a process for updating the power mask information.

  When power mask information is set for the first time or when power mask information is subsequently updated, the power mask information setting unit 5 notifies the acquired power mask information to an electronic device connected to the same UWB wireless communication network as the own device. To do.

  At this time, the power mask information setting unit 5 determines whether or not the electronic device to be communicated is in the on state, and notifies the acquired power mask information to the electronic device whose on state is confirmed. Incidentally, power mask information is notified to an electronic device whose off state is confirmed when the electronic device is turned on.

(B-2) Functional Configuration of Electronic Device that Receives Power Mask Information from Other Device FIG. 4 shows a functional configuration example of an electronic device 31 that receives power mask information from another device.

  The electronic device 31 includes a power mask information setting unit 33 as a wireless communication standard information setting function. The power mask information setting unit 33 corresponds to a “standard information setting unit” in the claims.

  In addition, in the case of the electronic device 31, in addition to the processing device corresponding to the power mask setting processing function, a computer system, a storage medium, a UWB wireless communication device, a user interface, and the like for controlling the entire system are mounted.

  Here, when the power mask information is notified from another device connected to the UWB wireless communication network, the power mask information setting unit 33 matches the power mask information stored in the own device with the received power mask information. If both do not match, a process of updating the power mask information stored in the own device with the notified power mask information is executed.

  The electronic device as the other device includes not only an electronic device equipped with the power mask information acquisition unit 3 but also an electronic device to which the power mask information received from the power mask information acquisition unit 3 is transferred.

  In the case of the power mask information setting unit 33, the power mask acquired by the electronic device connected to the same UWB wireless communication network as that of the own device when the power mask information is set for the first time or when the power mask information is subsequently updated. Transfer information.

At this time, the power mask information setting unit 33 excludes the electronic device that has received the notification of the power mask information from the transfer destination.
The power mask information setting unit 33 determines whether or not the electronic device to be communicated is in an on state, and notifies the acquired power mask information to the electronic device whose on state is confirmed.

  Incidentally, power mask information is notified to an electronic device whose off state is confirmed when the electronic device is turned on.

(C) Power Mask Setting Operation Example Hereinafter, power mask information automatic setting operation executed between electronic devices connected to the UWB wireless communication network will be described.

(C-1) Construction Procedure of UWB Wireless Communication System First, the construction procedure of the UWB wireless communication system is shown.
When a plurality of electronic devices are wirelessly connected to each other, first, negotiation processing is started with a cable connection or the like as a trigger.

  In the negotiation process, for example, it is confirmed whether the other party's electronic device supports the same UWB wireless communication function. Through this negotiation process, initial setting for wireless communication is executed.

  After completion of the initial setting, each electronic device is ready for wireless communication. Thereafter, each electronic device executes power mask setting processing based on a function for setting information related to the power mask of the own device (hereinafter referred to as “power mask information”).

(C-2) When the setting of power mask information in one network is completed A case where the automatic setting process of power mask information is completely executed in one network will be described with reference to FIG.

  The UWB wireless communication network 41 shown in FIG. 5 includes a computer (PC) 43 that operates as a host device, a portable music player 45 that operates as a device device, a television receiver 47, a mobile phone 49, a scanner 51, a printer 53, and the like. It is composed of peripheral devices.

  In the UWB wireless communication network 41, description will be made assuming that a host device and a device device are set.

  It is assumed that the UWB wireless communication network connecting the mobile phone 49 is constructed by a computer 43 that operates as a host device and other peripheral devices that operate as device devices.

  In this case, the mobile phone 49 executes processing for acquiring power mask information corresponding to the area of use, and the acquired power mask information is transferred to all other device devices via the computer 43 that operates as a host device.

FIG. 6 shows a processing procedure executed by the mobile phone 49. The cellular phone 49 executes the above-described initial setting process (S1).
Thereafter, the mobile phone 49 executes a process for acquiring power mask information (S2). In the power mask information acquisition process, the process shown in FIG. 7 is executed.

  The mobile phone 49 acquires location information using a GPS receiver or the like mounted on the own device or another device (S11). After that, the mobile phone 49 specifies the country or region in which the detected location information is included (S12).

Thereafter, the mobile phone 49 selects power mask information corresponding to the country or region with reference to the reference table (S13).
The mobile phone 49 that has acquired the power mask information by the above processing procedure starts the power mask setting process (S3). In the power mask setting process, the process shown in FIG. 8 is executed.

  First, the mobile phone 49 compares the power mask information held by itself with the acquired power mask information (S21). If the two match, the mobile phone 49 maintains the current setting (S22), and if both do not match, the mobile phone 49 updates its own setting to the newly acquired power mask information (S23).

  Next, the cellular phone 49 confirms the power state of the computer 43, which is a host device (S4). If the computer 43 is on, the mobile phone 49 notifies the computer 43 of power mask information acquired by the mobile phone 49 using the wireless communication function (S5). When the computer 43 is in the off state, the mobile phone 49 periodically repeats the confirmation operation until the on state is confirmed.

  On the other hand, the computer 43, which is a host device, executes power mask information setting processing and transfer processing to peripheral devices according to the processing procedure shown in FIG. First, the computer 43 starts a power mask setting process (S31). The contents of this setting process are the same as those shown in FIG.

  Next, the computer 43 checks the power state of the portable music player 45, the television receiver 47, etc., which are device devices (S32). When the power status of each device is confirmed, the computer 43 transfers the notified power mask information to the device devices other than the cellular phone 49 and in the on state (S33). The computer 43 periodically repeats the confirmation operation until the ON state of the device device that could not be transferred is confirmed.

  In FIG. 10, the setting path | route of the power mask information in the case of this operation example is shown by an arrow. With this setting operation, the power mask information of all the electronic devices connected to the UWB wireless communication network is automatically set to a state suitable for the country of use or the region.

(B) When the power mask information acquisition unit is mounted on the host device Hereinafter, an operation when the computer 43 on which the power mask information acquisition unit 3 is mounted is added as a host device to the UWB wireless communication network will be described. To do. That is, the operation contents when the computer 43 acquires the power mask information corresponding to the use region and notifies all the other device devices of the acquired power mask information will be described.

  The computer 43 that has completed the initial setting process acquires location information by using a GPS receiver or the like installed in the own device or another device, and identifies a country or region in which the acquired location information is included. Next, the computer 43 refers to the reference table and selects power mask information corresponding to the corresponding country or region.

  When the power mask information is confirmed, the computer 43 compares the power mask information held by itself with the newly acquired power mask information, and if the two do not match, the computer 43 adds the power mask information to the newly acquired power mask information. Update the settings.

  Next, the computer 43 confirms the power state of all electronic devices in the UWB wireless communication network operating as a device device. Then, the computer 43 notifies the power mask information acquired by the own device to all the device devices whose ON state has been confirmed.

  In FIG. 11, the setting path | route of the electric power mask information in the case of this operation example is shown by the arrow. With this setting operation, the power mask information of all the electronic devices connected to the UWB wireless communication network is automatically set to a state suitable for the country of use or the region.

(C-3) Case where power mask information is automatically set over a plurality of networks A case where the power mask information automatic setting process covers a plurality of networks will be described with reference to FIG. In FIG. 12, parts corresponding to those in FIG.

(A) When automatically setting power mask information across two networks Here, following the setting of power mask information for the UWB wireless communication network 41, another UWB wireless communication network 61 set in the same space A case where the power mask information is automatically set will be described.

  The setting of power mask information in the UWB wireless communication network 61 is executed through electronic devices belonging to the two networks. Note that this electronic device may operate as a host device or a device device in the UWB wireless communication network 61.

13 and 14 show an operation example when the printer 53 operates as a host device of the UWB wireless communication network 61. FIG.
In this case, since the printer 53 belongs to two networks, the power mask information received addressed to each device device of the UWB wireless communication network 61 different from the UWB wireless communication network 41 from which the printer 53 has received the power mask information. Forward.

As a result, the power mask information can be updated also for the digital video camera 63 and the digital camera 65 belonging to the UWB wireless communication network 61.
Note that if the electronic devices belonging to the two networks are also device devices in different networks, the power mask information is transferred via the host device.

FIG. 15 is a diagram for explaining this transfer example. FIG. 15 shows a case where the electronic device connected to the UWB wireless communication networks 41 and 61 is a digital camera 65.
In this case, the digital camera 65 transfers the received power mask information to a host device of a UWB wireless communication network 61 different from the UWB wireless communication network 41 that has received the power mask information.

  In the case of FIG. 15, the host device is the printer 53. In this case, the printer 53 that has received the power mask information transfers the power mask information to device devices belonging to the UWB wireless communication network 61 (except the digital camera 65 that has received the power mask information). That is, the printer 53 that operates as a host device transfers power mask information to the digital video camera 63 that operates as a device device.

Any transfer operation is executed based on the processing operation shown in FIG.
As described above, for an electronic device that overlaps with two networks, the function of transferring the power mask information to another network different from the network that has received the power mask information is installed. Can be updated at once.

(B) In the case where power mask information is automatically set over n (n is 3 or more) networks Here, following the setting of power mask information for the UWB wireless communication network 41, the two set in the same space The case where the power mask information is automatically set also for the UWB wireless communication network 61 described above will be described.

  FIG. 16 shows an example of setting power mask information when n UWB wireless communication networks exist in the same space. In the case of FIG. 16, it is assumed that each network 71 (1) to 71 (n) has one electronic device connected to another network.

  Further, it is assumed that the power mask information acquisition unit 3 is mounted on a computer 73 that operates as a host device of the first network 71 (1).

  In this case, the computer 73 transfers the power mask information to device devices (portable music player 75, television receiver 77, mobile phone 79, scanner 81, digital camera 83) connected to the same network 71 (1). Update the power mask information of each device.

  Here, the digital camera 83 is also connected to the second network 71 (2) and operates as its device. Therefore, the digital camera 83 transfers the power mask information to the printer 85 that is the host device of the second network 71 (2).

  Thereafter, the printer 85 transfers the power mask information to the device device (digital video camera 87) connected to the same network 71 (2), and updates the power mask information of each device device.

  The printer 85 is also connected to the third network 71 (3) and operates as its device. Therefore, the printer 85 transfers the power mask information to the computer 89 that is a host device of the third network 71 (3).

  Thereafter, the computer 89 transfers the power mask information to the device devices (scanner 91, music player 93, digital camera 95) connected to the same network 71 (3), and updates the power mask information of each device device.

  Here, the digital camera 95 is also connected to the fourth network 71 (4) and operates as its device. For this reason, the digital camera 95 transfers the power mask information to the computer 97 that is a host device of the fourth network 71 (4).

Thereafter, the computer 97 transfers the power mask information to the device devices (DVD player 99, television receiver 101, music player 103) connected to the same network 71 (4), and the power mask information of each device device is transferred. Update.
Thereafter, the above-described operation is repeated up to the n-th network 71 (n).

(C-4) Effect of Embodiment As described above, if a UWB wireless communication network is constructed by an electronic device equipped with a power mask information acquisition function and a transfer function, the power mask information acquisition unit 3 is installed. It is possible to set power mask information of all electronic devices constituting the wireless network to power mask information suitable for the use area at a timing when one electronic device is newly connected to the network.

  That is, even when a person or an object crosses a region or a border, the user can execute the power mask information setting process for all the electronic devices without performing any special work. For this reason, it is possible to reliably eliminate omission of settings when moving between regions and countries.

  Moreover, in the case of the power mask information setting function proposed by the inventor, the power mask information can be automatically set even for an electronic device that cannot communicate directly or an electronic device that belongs to another network.

(D) Other embodiments (D-1) Other country or region setting method In the case of the above description, the location information of an electronic device is detected using a GPS receiver or a wireless LAN, and based on the location information. The case where the country or region is automatically set was explained.

However, the user may directly input the country or region. This method is effective when a GPS receiver or the like cannot be used.
Moreover, when using the detection result of a GPS receiver etc., you may combine the process step which calculates | requires a user's permission before specifying a country or an area.

  That is, the country or region acquired using a GPS receiver or the like is displayed on the display unit of any electronic device, and the power mask information is set using the acquired result only when the user's permission is obtained. Processing may continue.

  By combining this processing procedure, it is possible to avoid a situation in which all electronic devices are set to incorrect power mask information due to a determination error or the like.

(D-2) Electronic Device that Performs Transfer Processing Between Networks In the case of FIG. 16, a case has been described where both electronic devices belonging to two networks operate as device devices in each network.

(D-3) Electronic Device Mounting Power Mask Information Acquisition Unit In the case of the above-described embodiment, the case where one power mask information acquisition unit 3 is mounted on one electronic device has been described.
However, a plurality of power mask information acquisition units 3 may be mounted on one electronic device. Alternatively, a plurality of electronic devices in which the power mask information acquisition unit 3 is mounted may exist in one network.

Of course, even if there are a plurality of power mask information acquisition units 3 in one network, there is no problem as long as the power mask information is set a plurality of times.
It should be noted that the setting accuracy of the power mask information can be increased by utilizing the presence of a plurality of power mask information acquisition units 3.

  That is, the power mask information acquired by each power mask information acquisition unit 3 is compared, and the setting accuracy of the power mask information is increased by continuing the power mask information setting process only when the power mask information matches. Can be increased.

  If a mismatch of power mask information is detected, it is desirable to present the result to the user. In this case, the power mask information determined by the user's instruction input may be used to execute the power mask information setting process for each electronic device.

(D-4) Other Configuration Examples of Electronic Device In the above description, the case where the power mask information is notified to all other electronic devices from the electronic device equipped with the power mask information acquisition unit has been described.

May be specified.

  FIG. 17 shows a configuration example of the network system. In the case of FIG. 17, the electronic device 111 notifies the location information to another electronic device 113. The power mask information acquisition unit 115 of the electronic device 113 selects optimal power mask information based on the notified location information. However, depending on the case, the power mask information acquisition unit 115 executes the specification of the country or region and the setting of the power mask information.

  On the other hand, the power mask information setting unit 117 performs the same processing as the processing operation described above. That is, the power mask information setting unit 117 performs a comparison process between the power mask information acquired by itself and the stored power mask information, a power mask information update process based on the comparison result, and a power mask information transfer process. .
