Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system that utilizes a radio wave shielded space for shielding radio waves, and in particular, realizes distribution of exclusive contents, reliable operation control of electric devices, and accurate position identification of mobile phones and the like. The present invention relates to a radio wave shielded space communication system, a radio wave shielded space device control system, a position specifying system, and a radio wave shielded space communication device.

[0002]

2. Description of the Related Art Recently, various contents are distributed to mobile phones, and mobile phones are used for other purposes such as making phone calls, e-mails, and browsing the Internet. Various attempts have been made to utilize it. In addition, GPS (Global Po
PH using (positioning Systems)
S (Personal Handyphone Sys
tem) is being sought for a system for specifying the position of a mobile phone with an accuracy equal to or higher than the position specification by tem).

[0003] Along with the increase in contents for mobile phones, a system for distributing contents limited to an area is disclosed in order to increase the value of the contents to be distributed.
No. 11128. This system is shown in Figure 1.
As shown in FIG. 3, when the information distribution center 1 receives the transmission signal from the mobile phone 2, the information distribution center 1 detects the location area of the mobile phone 2 from the information received via the base station 3c and holds it by itself. Region-specific content in the area where the mobile phone 2 is located is extracted from the database and distributed.

Regarding the expansion of applications of mobile phones,
Many attempts have been made to use a mobile phone as a remote controller for various electric devices such as so-called IT home appliances such as televisions, videos, and air conditioners that can be connected to a network, and some of them have been realized. . For example, there is provided a system that enables remote operation by associating a mobile phone and an electric device to be controlled with Bluetooth, which is a short-range wireless communication standard.

Further, a system for specifying the position of a mobile phone is also realized by using a fixed communication area of a base station. This system will be described with reference to FIG. 13. The base stations 3a to 3d have communication areas A1 to A4 of a fixed area.
On the other hand, the mobile phone 2 has the nearest base stations 3a to 3d.
It has the property of communicating via the Internet. Therefore, the information distribution center 1 or the like recognizes the base stations 3a to 3d that have received the communication from the mobile phone 2, thereby identifying that the mobile phone 2 is located in the communication area of the recognized base station. I have to.

[0006]

In the system for distributing local content shown in FIG. 13, the local content may not be provided accurately depending on the position of the mobile phone 2. That is, since the communication areas A1 to A4 of the base stations 3a to 3d have a circular shape due to the communication characteristics,
In order to eliminate the incommunicable area of the mobile phone 2 as much as possible, the base stations 3a to 3d are arranged so that the communication areas A1 to A4 partially overlap each other. For this reason,
When the overlapping portions B1 to B3 occur in the communication areas A1 to A4 and the mobile phone 2 is located in the overlapping portion B3, for example, the limited content of the base station 3c and the limited content of the base station 3d are obtained, and the area is limited. Then, there is a problem that the concept of delivering dedicated content is diluted.

[0007] Depending on the contents to be distributed,
Even if the distribution areas of the content limited to the area are mixed in this way, no particular trouble may occur. However, when the content to be distributed requires security, it becomes an important problem.

Further, when the mobile phone is used as a remote controller for various electric devices, when there are a plurality of mobile phones operable by the electric device around the electric device to be operated, the mobile device attempts to operate the electric device. The electric device may be operated by a mobile phone other than the phone. For example,
If one of the two adjacent rooms has a set of mobile phones and electrical equipment compatible with the wireless communication standard and the other room has a mobile phone of the same wireless communication standard, the electrical equipment in one room There is a problem that it operates in response to the operation of the mobile phone in the other room.

Furthermore, when another person owns a mobile phone that supports the same wireless communication standard, the other person can operate his / her own electric equipment, and the electric equipment can be operated without the owner's knowledge. There is also a risk that it will be operated arbitrarily.

On the other hand, with respect to the system for specifying the position of the mobile phone, since the overlapping area of the communication area occurs similarly to the distribution of the content, when the mobile phone is located at the overlapping area, the mobile phone can be accurately located. There is a problem that the position of can not be specified. In addition, the location of each base station based on the communication area basically targets two dimensions on a plane. For example, when a mobile phone is located on the third floor of a building, it is said to be located on the third floor. There is a problem that can not be realized until three-dimensional position identification. The fact that a three-dimensionally accurate position cannot be specified is the same in PHS using GPS.

The present invention has been made to solve such a problem, and forms a radio wave shielded space in which radio waves from the outside are shielded, and a radio wave communication means is provided in the radio wave shielded space to provide a mobile phone. An object of the present invention is to provide a radio wave shielded space communication system and a radio wave shielded space communication device in which the usability of a portable communication device such as a device is improved. Further, the present invention provides a radio wave shielded space communication system in which a content exclusive to the radio wave shielded space can be obtained by distributing a dedicated content related to the radio wave shielded space from the radio wave communication means in the radio wave shielded space. To aim.

Further, according to the present invention, an electric device which can be controlled by a control signal is arranged in the electric wave shielding space, and information relating to operation items can be distributed so that the electric device can be reliably operated by a portable communication device. An object is to provide a communication system. Furthermore, according to the present invention, the electric device determines the operating-side portable communication device based on the identification information, enables only the specific portable communication device to operate, and prevents malfunction and enhances security. The purpose is to provide a control system.

Further, according to the present invention, the position of the portable communication device can be accurately specified from the outside by providing the relay means for relaying the communication between the radio wave shielded space and the outside and adding the identification signal to the communication contents. The purpose is to provide a specific system.

Next, the processing relating to the distribution form of the content by the radio wave shielded space communication system 10 will be described with reference to the flow chart of FIG. 3, focusing on one mobile telephone 16-1. In addition, this flowchart is for mobile phone 1
First, 6-1 is the radio wave shielded space 1 provided in the building 11.
3 shows the flow of processing for the case of being located outside 3 and then moving into the radio wave shielded space 13.

First, the mobile phone 16-1 makes a call to receive distribution of contents (S1). This call is received by the base station 19 in the immediate vicinity of the mobile telephone 16-1 because the mobile telephone 16-1 is located outside the radio wave shielded space 13, and the exchange 18 is transmitted via this base station 19.
A communication connection with is established (S2).

By establishing the communication connection in this manner, the general contents stored in the general server 15-2 can be distributed from the exchange 18 to the mobile phone 16-1, and the mobile phone can be delivered. 16-1 receives the desired general content by the required operation (S3). In the reception state of this general content, the mobile phone 16-1 is in the building 11

Due to the above-described movement of the mobile phone 16-1, the communication connection that has been established through the base station 19 outside the building 11 until now is blocked by the radio wave from the mobile phone 16-1. By being blocked by the radio wave blocking member 12 in the space 13, the communication connection is automatically taken over by the connection via the in-space base station 14 and the relay device 17, and the established communication connection is maintained (S5).

Since this handed-over communication connection is made by the in-spatial base station 14, the exchange 18 makes the portable telephone 16
-1 recognizes that the communication connection by -1 has been switched to the one via the in-spatial base station 14, and the content distributed to the mobile phone 16-1 is transferred from the general content of the general server 15-2 to the in-spatial base station 14 Space server 1 connected to
The content is automatically switched to the dedicated content 5-1 (S6). Therefore, the mobile phone 16-1 can easily obtain the dedicated content related to the radio wave shielded space 13 only by entering the inside of the radio wave shielded space 13 without any special operation.

Further, the distribution of the above-mentioned exclusive contents is once interrupted, and the portable telephone 16 is inserted from the inside of the radio wave shielded space 13.
If a new call is made at -1, the communication connection is established via the in-spatial base station 14 and the relay device 17. in this case,

As shown in FIG. 1, when another mobile phone 16-2 located near the outside of the building 11 makes a call to receive the distribution of contents, the radio wave generated by this call is a radio wave. It is reflected by the radio wave shielding member 12 in the shielded space 13 and does not reach the in-space base station 14. Therefore, building 1
The other mobile phone 16-2 located outside 1 cannot receive the dedicated content of the space server 15-1.

As a result, in order to receive the distribution of the dedicated contents in the radio wave shielded space 13, it is necessary to enter the inside of the radio wave shielded space 13, that is, the building 11, and the rarity and value of the dedicated contents. Building 1 that enables distribution of such exclusive content
The degree of attention of 1 can also be increased.

Further, as the distribution contents of the exclusive contents,
The in-space base station 14 is shown in FIG.
First, the menu content D-1 of (a) is distributed.
Mobile phone 1 that received the menu contents D-1
The user of 6-1 selects a desired item from each item. The information that this item has been selected is available in the space base station 1
4 and the secondary content D-2 shown in FIG. 2B corresponding to the content of this information is distributed by the in-spatial base station 14. Thereafter, in the same manner as described above, the in-spatial base station 14 determines the space server 1 according to the item selected by the mobile phone 16-1.
Various dedicated contents stored in 5-1 are extracted and distributed, and these dedicated contents can be browsed by the mobile phone 16-1.

On the other hand, the mobile phone 16-1 located inside the radio wave shielded space 13 is replaced with another mobile phone 16-2 outside.
When making a call to, it is possible to make a call without changing anything. For example, when the telephone number of the external mobile telephone 16-2 is called from the internal mobile telephone 16-1, the contents of the call are transmitted from the spatial base station 14 to the external exchange station via the relay device 17. 18 is transmitted. The exchange 18 uses the telephone number as a clue to call the other mobile phone 16-2 from the base station 19 where the other mobile phone 16-2 is located. If the other mobile phone 16-2 responds to this call, the communication is established and the internal mobile phone 16-1 is connected.
A call can be made between the mobile phone and the external mobile phone 16-2.

The radio wave shielded space communication system 10 of the present embodiment is not limited to the above-mentioned form, and various modifications are possible. For example, in FIG. 1, the in-spatial base station 14 and the space server 15-1 are connected by a connection line C1, but the space server 15-1 is provided with a wireless communication means to be connected by wireless communication. Good.

In case of connecting with a connecting line, FIG.
As shown in (a), the space server 25-1 is connected to the building 2
1 is arranged outside the radio wave shielded space 23 formed by the radio wave shield member 22 instead of inside the server 25-1.
And an in-space base station 2 arranged inside the radio wave shielded space 23
4 may be connected to each other by a connection line C21 provided from the outside to the inside of the radio wave shielded space 23. In this way, the space server 25-1 can be arranged outside without being restricted by the radio wave shielded space 23, so that the space server 25-1 can be shared with a plurality of other radio wave shielded spaces.

The space server 45 stores the exclusive contents for each floor, and extracts the exclusive contents of the corresponding floor according to the in-spatial base stations 44-1 to 4-5 which communicate with the portable communication device, The dedicated contents on each floor are distributed through the base stations 44-1 to 44-5 in the space on the floor. By doing so, the content to be delivered can be switched to the content for each floor only by moving the mobile communication device up and down.

The space server 45 can also pre-register the telephone numbers of the mobile phones 46-1 and 46-2 used in the building 41. By placing the mobile phone 46- from the base station 44-2 in the space on the second floor from outside the building 41 via the relay device 47.

FIG. 6 shows another modification of a radio wave shielded space communication system 50, which is an optical fiber cable H laid near a building 51 in which a radio wave shielded space 53 is formed by a radio wave shield member 52. The wireless relay Ha of the terminal is used as a communication destination of the relay device 57 in the radio wave shielded space 53. Therefore, when the mobile telephone 56 located inside the radio wave shielded space 53 communicates with the outside of the radio wave shielded space 53, the in-space base station 5 integrated with the space server 55.
The radio wave T3 is output to the outside from the relay device 57 via the relay unit 4.

In No. 0, even if the optical fiber cable H is not pulled into the building 51, communication by the optical fiber cable H is easily realized outside the radio wave shielded space 53, and the optical fiber cable can be used at low cost.

Embodiment 2. The position identification system according to the second embodiment has the same hardware configuration as the radio wave shielded space communication system 10 shown in FIG. 1, and the position identification system is configured based on the same components and reference numerals as in FIG. This will be described below. When the mobile phone 16-1 is located inside the radio wave shielded space 13, this position specifying system specifies the current position of the mobile phone 16-1 by communicating with the exchange 18 using the relay device 17. . In the position identifying system, the position search menu D- shown in FIG.
3 and the position specifying content D-4 for the map data of each place shown in FIG. 7B is stored.

When the mobile phone 16-1 specifies its own position, first, the mobile phone 16-1 makes a call to the exchange 18 via the spatial base station 14 and the relay device 17. In response to this call, the exchange 18 extracts the position search menu D-3 shown in FIG. 7A from the general-purpose server 15-2 and, via the relay device 17 and the in-spatial base station 14, the mobile phone. It will be delivered to 16-1. From the location search menu D-3 to the mobile phone 16-1, select "YE
By selecting “S”, the information regarding the position identification request is transmitted to the exchange station 18 via the in-spatial base station 14 and the relay device 17. At the time of this transmission, the relay device 17 adds its own ID information to the transmission content.

The exchange 18 detects the added ID information, and based on the detected ID information, the mobile phone 1
6-1 determines at which position the relay device 17 has performed communication, and thus the relay device 17, that is, the mobile phone 16-
The position of 1 is specified. This identified position is shown in FIG.
As the geographical information shown in (b), the position specifying content D-4 is created with the mark P attached to the corresponding position of the map data, and is distributed to the mobile phone 16-1.

The mobile telephone 16-1 can easily confirm the present location of the user by browsing the position specifying content D-4. Further, the position specifying content D-4 can also be distributed to the mobile phone 16-2 outside the radio wave shielded space 13, and the external mobile phone 16-2 can receive the position specifying content D-4. Then, the position of the mobile phone 16-1 can be grasped.

The position of the mobile phone 16-1 is not exactly the position of the mobile phone 16-1 but the relay device 17-1.
Since the exchange station 18 is located at the position of 1, the exchange station 18 can recognize that the mobile phone 16-1 is located inside the radio wave shielded space 13, but cannot identify where in the radio wave shielded space 13 it is located. Therefore, an error corresponding to the space size of the radio wave shielded space 13 occurs. Therefore, in order to prevent the accuracy of position identification from deteriorating when the radio wave shielding space 13 is large, the radio wave shielding space 13 is divided into a large number of radio wave shielding spaces, and the divided radio waves having small dimensions are used. It is preferable to provide the relay device 17 for each shielded space.

Further, the same modified example as that of the first embodiment can be applied to the position specifying system according to the second embodiment, and the system is constructed with the same configuration as the radio wave shielded space communication system 40 shown in FIG. 5, for example. You may do it. In this case, the space server 45 is the base station 44 in the space on any floor.
-1 to 5 recognizes whether the mobile phones 46-1 and 46-2 are communicating, and when the position specifying system is operating, the recognized in-spatial base station 44-1
Floor information for determining which floor the items 5 to 5 correspond to is also transmitted to the external exchange through the relay device 47 as identification information.

Therefore, the mobile switching center exchanges the portable telephone set 46-1 whose position is to be specified based on the ID information of the relay device 47.
It is possible to specify a two-dimensional position such as, and also to specify which floor the mobile phone 46-1 or the like is three-dimensionally located based on the floor information. Therefore, even the three-dimensional position can be taught by distributing the specified information to various portable communication devices located inside and outside the requested building 41.

When the three-dimensional position is specified in this way, the position specifying system 60 shown in FIG. 8 may be used. That is, the position identifying system 60 forms the radio wave shielding spaces 63-1 to 5 with the radio wave shielding members 62-1 to 6-5 for each floor of the five-story building 61, and these radio wave shielding spaces 63-1 to 6-5 are formed. Space base stations 64-1 to 5 and space servers 65-1 to 5 are arranged inside, and relay devices 67-1 to 5 are provided.

Each of the relay devices 67-1 to 5-5 has its own ID information, and the exchange outside the building 61 is connected to each relay device 67-1.
The positions of -1 to 5 are registered in advance in association with the ID information including the three-dimensional position. By doing so, for example, the mobile phone 66 located on the second floor can identify the position of itself by the in-spatial base station 64-2 and the relay device 67-.
When the position specifying request information is transmitted to the external exchange through 2 through 2, the external exchange includes the three-dimensional position of the mobile phone 66 based on the ID information of the relay device 67-2. I can identify it.
