Here, the information guide system of this embodiment is applied to the theme park 5 shown in FIG. 10, and the organization that operates the theme park 5 provides various kinds of guidance to the users who have entered the theme park 5. A case where information is provided will be described. First, when the user enters the theme park 5, the user is given the mobile station 1 ₁ . Theme park 5
If the user carrying the mobile station 1 ₁ ... Does not know the route to the place he wants to go, the user calls a specific dial number from the mobile station 1 ₁ . Call the information center 4 and ask the information center 4 for directions to where you want to go. The information processing center 4 called from the mobile stations 1 ₁ ...
However, as described above, the location information of the mobile stations 1 ₁ .
The transmitting means 41 transmits the directions from the place to the place where the user wants to go to the mobile stations 1 ₁ .

[0026] For example, a user carrying the mobile station 1 _3,
When asking the information guidance center 4 for the nearest toilet, the information processing center 4
Carrying the mobile station 1 ₃ user detects that are in between the base station 2 ₄ and attractions 53 _5, the nearest toilets, it is determined that the toilet 57 ₅ in the Western attraction 53 _5, the communication unit sends the guidance information to the mobile station 1 to ₃ from 41, to the user who carries the mobile station 1 to _3, for example, "the nearest toilets are 57 _5. was carried out 50m and is from here to the southwest of direction There is a guide information.

As described above, the user who possesses the mobile station 1 ₁ ... Can provide guidance information to the place he wants to go, regardless of where he is in the theme park 5 or where he is. Can receive. (Embodiment 2) By the way, in wireless communication such as PHS,
If the digital signals transmitted and received between the mobile station 1 and the base stations 2 ₁ ... On the radio wave carrier are not synchronized, communication cannot be performed normally, so that the mobile station 1 and the base station 2
₁ ... and must synchronize the digital signals between the mobile station 1 is in synchronization with the slot that is transmitted from the base station 2 _1, and has a function of transmitting a signal to the base station 2 _1. Therefore, it is easy to detect how much the digital signal sent from each of the base stations 2 ₁ ... Is delayed from the synchronization state. For example, although the detection unit 14 of Embodiment 1, the mobile station 1 detects the electric field intensity of radio waves transmitted from the 2 ₁ ... each base station, in the present embodiment, the detection means 14 each base station 2 ₁ ... The delay time of the digital signal sent from the PC is detected. Then, the notification unit 15 via the base station 2 ₁ ... and switch 3, the delay time of the signal from the 2 ₁ ... each base station detected by the detection means 14, and transmits to the information guidance center 4.

On the other hand, as shown in FIG. 3, the base station 2 includes synchronization means 26 for synchronizing with another base station 2 and transmitting a digital signal to the mobile station 1. Here, in the first embodiment, the detecting unit 24 detects the electric field strength of the radio wave received from the mobile station 1, but in the present embodiment,
The detecting means 24 detects how much the digital signal on the radio wave carrier received from the mobile station 1 is delayed from the synchronous state, and the notifying means 25 transmits the detection result of the delay time to the information guidance center 4.

In the information guidance center 4, the communication means 41
Receive the detection result of the delay time transmitted from the mobile station 1 or the base stations 2 ₁ . Since the propagation speed of the radio wave in the air is constant, the analysis processing means 42 obtains the delay time of the radio wave and the base station 2 ₁ . The distance to can be obtained. As a result, as shown in FIG. 4, the analysis processing unit 42 narrows the range in which the mobile station 1 is expected to be located to a substantially annular expected area B ₁ ... Centered on each base station 2 ₁ . can, it is possible to determine that the mobile station 1 to all expectations area B ₁ ... areas B ₄ overlapping is present, obtain location information of the mobile station 1. And information guidance center 4
Calculates the position information of the mobile station 1
It is possible to provide the optimal guidance information at the current position of the user having the information.

In the first embodiment, the distance between the mobile station 1 and the base stations 2 ₁ ... Is determined from the electric field strength of the radio wave detected by the detecting means 14, 24. May not be constant due to interference with other mobile stations, base stations, or other wireless communication systems. On the other hand, in the present embodiment, the detection means 14 and 24 detect the delay time of the digital signal, and the detection error range of the delay time depends only on the accuracy of the time measurement. The current position of the mobile station 1 can be detected with higher accuracy as compared to the case in which the mobile station 1 is used.

[0031] Incidentally, although the expected area B ₁ ... has a substantially annular, the result of the processing of the analysis processing unit 42, the expected area may be a range of other substantially annular. Further, the detecting means 14,
The configuration of the information guidance system other than 24 and the synchronizing means 26 is the same as that of the first embodiment, and a description thereof will be omitted. In (Embodiment 3) Embodiments 1 and 2, and radio field strength between the mobile station 1 and base station 2 ₁ ..., the delay time of the digital signals, between the mobile station 1 and the base station 2 ₁ Although the distance is obtained and the position information of the mobile station 1 is obtained, in the present embodiment, as shown in FIG. 5, the directional antennas 21 ′ each having a directivity of about 15 degrees are provided to the base station 2. The 24 directional antennas 21 'are provided at intervals of about 15 degrees in the horizontal plane so that radio waves can be received over the entire circumference in the horizontal plane. And detecting means 2
Reference numeral 4 denotes a directional antenna 21 'that receives a radio wave from the mobile station 1 with the strongest electric field strength among the 24 directional antennas 24', and detects an electric field strength of the radio wave received by the directional antenna 21 '. I do. Since the mobile station 1 is located in the direction in which the directional antenna 21 'receives the radio wave from the mobile station 1 with the strongest electric field strength, the notifying means 25 sends the electric field strength of the radio wave received by the directional antenna 21'. At the same time, the direction in which the directional antenna 21 ′ is directed is transmitted to the communication means 41 of the information guidance center 4 as the azimuth information of the mobile station 1.

Here, assuming that the output of the mobile station 1 is fixed and the position of the base station 2 is known, the analysis processing means 42
Is the distance between the base station 2 and the mobile station 1 based on the electric field strength of the radio wave from the mobile station 1 received by the communication means 41 based on the conversion formula between the attenuation of the electric field strength of the radio wave and the propagation distance. Can be requested. In addition, the analysis processing means 42
, The position of the mobile station 1 can be obtained from the azimuth information and the distance from the base station 2 to the mobile station 1.

For example, in the PHS, the range of radio waves of the base station 2 is about 100 m in radius as a standard, though it varies depending on the output of the base station 2 and the installation location. Therefore, if the directivity of the directional antenna 21 'is set to about 15 degrees, the mobile station 1
Can be detected with a maximum error of about 26 m. Further, since the current position of the mobile station 1 can be detected by only one base station 2, there is no need to install many base stations 2 as in the first or second embodiment, and the entire system can be simplified. Thus, the cost required for constructing the system can be reduced.
