Description

  The present invention relates to a radio wave condition management system and a radio wave condition measurement method, and more particularly, to a radio wave condition measurement method and a radio wave condition management system that collect radio wave condition measurement information without running an electric vehicle or the like.

In Land Mobile Radio (LMR), in addition to in-vehicle, portable, and shoulder-type portable devices, various mobile communication terminals (including these) In recent years, digitization has been promoted from the viewpoint of effective use of radio waves and downsizing of devices.
In a digital wireless communication system, data to be transmitted is transmitted and received in units of frames. On the transmitter side, a synchronization signal having a specific signal arrangement pattern at a predetermined position of each frame (Frame Sync Word: “FSW”) The receiver side establishes synchronization by detecting the frame synchronization word in the detection output signal.
In addition, position detection devices using artificial satellites have also been miniaturized and have been incorporated into mobile communication terminals such as mobile phones. GPS units are installed in vehicle-mounted radios and radios carried by workers. Various systems have been established to grasp the position of the.

By the way, a new installation of a commercial wireless system requires considerable equipment costs, and even when receiving the provision of existing services, in addition to subscription costs, purchase of mobile communication terminals and lease costs, etc. Since there are many cases, it is ideal to determine whether or not to introduce the system after confirming the effect of the system introduction. However, if a system that is introduced in the entire communication area in the hope of high communication quality without noise is contrary to the user's wishes, both the system providing side and the user side are hesitant to respond.
In particular, in areas with high-rise buildings in the city or areas with many mountains, there are radio-insensitive zones where radio waves do not reach everywhere, so it is essential to understand the radio wave conditions in areas where radio-insensitive zones may be included. .
Therefore, in order to grasp the state of radio wave propagation in the wireless communication area to be covered by the wireless communication system prior to the introduction of the system, it has been necessary to run an electric vehicle equipped with various measuring instruments and antenna equipment. Radio propagation measurement was performed.

FIG. 5 is a flowchart showing a correspondence example when the user wishes to introduce a wireless communication system or subscribe to a communication service. In the example shown in FIG. 5, when there is an inquiry about a wireless communication system from a user (S31), the user's desire and communication service area are heard, and a system and service subscription that is considered to satisfy the hope will be described (S32). At this point, if the user's consent is obtained, if covered by an existing communication service, communication is performed by temporary operation or demonstration running to test the usability using an actual communication system (S33), Based on the result, it is determined whether introduction is possible (S34).
However, if the existing communication service range does not include the communication area desired by the user, or if a completely different communication service is desired, provisional operation or demonstration cannot be performed. In the area, an electric measurement vehicle was run to conduct an electric measurement experiment (S35), and based on the result, it was determined whether or not introduction was possible (S34).

However, since the method of conducting the electric measurement experiment requires time and labor, and quick determination and system proposal are impossible, methods and means as described in Patent Document 1 and Patent Document 2 have been proposed. Has been.
The one described in Patent Document 1 is equipped with a notebook portable computer and a transmitter / receiver, a GPS position detection device, an antenna, and the like connected to the computer, and receives radio waves from the base station device while moving. In addition, the electric field strength information is acquired, and the electric field strength information is recorded on the displayed map information in the electric vehicle on the mobile communication terminal side based on the position information detected by the GPS. According to this method, it is possible to obtain data in which electric field strength information is associated on a map with relatively simple equipment.

Patent Document 2 proposes a radio wave condition measurement system including a mobile terminal, a mobile communication network, and a radio wave measurement system connected to the mobile communication network.
This system uses a function of precisely controlling and managing the electric field strength of a radio wave transmitted from a mobile phone (mobile communication terminal) of a public communication line system in a base station of a mobile communication network. That is, when a radio measurement start / end message is sent from the radio wave measurement system to the mobile communication network as necessary, management data information of a base station in a required area in the mobile communication network, for example, transmission power to the mobile terminal The control data and the field strength information of the radio wave transmitted from the base station in the portable terminal are returned to the radio wave measurement system. The mobile terminal returns position information detected by a built-in GPS-based position detection device, electric field strength information of radio waves from the above-described base station device, and the like in response to a telemetry instruction from the base station.

In the example described above, when performing radio wave condition measurement, for example, as shown in FIG. 6, polling data 11 for radio wave condition measurement is transmitted from the base station apparatus, and the mobile communication terminal returns a response signal 12 to it. Then, further, radio wave condition measurement data 13 is transmitted from the base station apparatus, and the mobile communication terminal performs measurement of electric field strength and bit error rate calculation by error correction processing while receiving the radio wave condition measurement data 13. The result is transmitted to the base station apparatus as radio wave status data 14.
According to this system, it is possible to grasp an accurate radio wave condition, and it can be used for a base station installation plan or the like for dead zone countermeasures.

It is to be received, and a telemetry experiment is performed as a separate work from the actual communication. Therefore, the user cannot confirm the actual feeling of use. Ideally, it is preferable that an actual feeling of use can be grasped as much as possible. Furthermore, it is normal to determine the radio wave condition after conducting the electric measurement experiment once, and it is economically and temporally to perform the electric measurement experiment in each situation with different seasons and weather conditions. In the end, it was impossible to obtain detailed measurement data that could be used to estimate the actual feeling of use in different radio wave environments.
The method described in Patent Document 2 uses a function of precisely controlling and managing the electric field strength of a transmission radio wave from a mobile phone (mobile communication terminal) in a mobile phone system as a public communication line at a base station of a mobile communication network. Therefore, the system is premised on the existence of a large-scale facility such as a telecommunications carrier that provides a public communication network, so it is difficult to use it when introducing a general commercial wireless communication system. there were.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely illustrative examples and not intended to limit the scope of the present invention only unless otherwise specified. .
FIG. 1 is a system outline diagram for explaining the basic concept of the present invention. In FIG. 1, (a) to (c) on the left side show communication between a base station apparatus (Station) St and a mobile communication terminal (Mobile) Mo by a conventional radio wave condition management system and radio wave condition management method. (D) has shown communication between the base station apparatus St and the mobile communication terminal Mo in this invention. The original purpose of the wireless system shown in this example is to mount a mobile communication terminal Mo as shown in FIG. 1 (a) in each of a plurality of transportation vehicles, and periodically or in order to grasp each operation state. If necessary, the mobile station Mo of each vehicle is sequentially called from the base station apparatus St, and processing (hereinafter referred to as polling) for returning business information such as position information and operation purpose at that time is performed and collected. This shows a case where the status of work is managed by displaying information on a display.

In such a radio system, when radio wave condition measurement is performed, as shown in FIG. 1B, radio wave condition measurement data (radio wave condition measurement request) is transmitted from the base station apparatus St to the mobile communication terminal Mo of each vehicle. Signal). Receiving this signal, the mobile communication terminal Mo detects position information at that time and preset radio wave condition information, and returns the information to the base station apparatus St.
Alternatively, as shown in FIG. 1C, as another method, when radio wave condition measurement data (radio wave condition measurement request signal) is transmitted from the base station device St to the mobile communication terminal Mo of each vehicle, the mobile communication terminal Mo Detects the position information at that time and the radio wave condition information set in advance, but stores the information in the memory of the mobile communication terminal Mo without returning it to the base station St, and later stores the information. There is also a way to collect.

However, as described above, the conventional method has various problems. Therefore, in the present invention, as shown in FIG. 1 (d), it is configured or controlled so that radio wave condition measurement is performed at all times or as necessary in the communication originally intended for the communication system. To do.
In general, the electric field strength literally refers to the level (strength) of the radio signal, and the radio wave status refers to the communication quality on the receiving side in accordance with the actual use state. . For example, the bit error rate and the signal-to-noise ratio (S / N) in data communication are similar to the radio wave situation, and it depends on the radio wave environment such as the presence or absence of external noise at the reception point and the presence of rain or fog that blocks radio wave propagation. It is what is done. However, in the present invention, the radio wave condition information includes the electric field strength value, and the electric field intensity value, the bit error rate, the S / N value, or other values may be used as the radio wave condition information. .

  In the embodiment, it is assumed that the base station St performs polling. However, in an actual usage situation, the mobile station Mo may arbitrarily transmit without polling from the base station St. That is, when the mobile station Mo has moved a set distance, entered a set area, set time has elapsed, changed state, and the like, the conditions are satisfied, Normal data is sent to the base station St. In the case of transmitting data from the mobile station Mo without polling from the base station St under the above conditions, it is not possible to add the measurement data of the transmission wave of the base station St and send it to the base station St. It is possible to measure the transmission wave of the mobile station Mo on the base station side (electric measurement on one side only).

FIG. 2 is a flowchart showing an embodiment of the radio wave condition measuring method according to the present invention. In this figure, the base station device St is shown on the right side and the mobile communication terminal Mo is shown on the left side, and the exchange of signals between them is shown. At the time of radio wave condition measurement, polling data for performing operation management polling processing is attached and transmitted from the base station device St to the mobile communication terminal Mo of each vehicle (S1).
This polling is performed for a vehicle or the like to be managed, and includes identification information of the mobile communication terminal Mo mounted on the target vehicle, a signal for specifying information to be returned, and the like. The information to be returned varies depending on the operation management object, but for example, in addition to position information, business daily report information such as shipper, destination, moving route information of the day, and the like can be considered. In the present invention, when the mobile communication terminal Mo receives these polling data (S2), it acquires the electric field strength data while receiving the radio wave from the base station device St and stores it in the memory (S3). .
Subsequently, during or after reception of radio waves from the base station apparatus St, error correction processing in radio wave reception from the base station apparatus St is performed (S4), and the number of error correction bits (Eb1) is obtained from the error correction processing information. Similarly, the electric field strength data and the error correction bit number (Eb1) stored in the memory (S5), attached to other necessary response signals, and stored together with the position information are returned to the base station device St (S6).

In the base station device St that has received this response signal (S7), the location information and other operation management data are processed to perform the operation management intended for the original communication system (S8), and the electric field strength returned simultaneously. Radio wave status management is performed based on the data and the number of error correction bits (Eb1) (S9).
The above processing may be periodically performed on one mobile communication terminal Mo to collect radio wave status information in the communication management area, but all or a plurality of mobile communication terminals Mo are required. If this is sequentially performed, it is possible to collect more detailed radio wave condition information. The radio wave status information collected in this way is stored in association with the map information in the communication jurisdiction based on the location information of the mobile communication terminal Mo.
In this example, the field intensity data and the number of error correction bits (Eb1) are used as the radio wave status information, but only one of the field intensity data and the number of error correction bits (Eb1) may be used. In radio wave condition management, if the acquired radio wave condition information is stored in association with, for example, seasonal information, weather information, time information, and other map information within the communication jurisdiction, more detailed data is accumulated. Is done.

The radio wave condition information collected in this way is read out as needed in accordance with the request of a customer who wishes to introduce a new wireless system, and the radio wave condition information is displayed on the display together with the map information. The communication status can be imagined. If a part of the actual call between the operator of the base station device St and the operator of the mobile communication terminal Mo at the time of polling is digitized and stored as part of the radio wave status information, the movement on the displayed map While watching the movement of the pointer indicating the position of the communication terminal Mo, it is possible to listen to the actual call voice at that time, so that it is possible to actually experience the feeling of use of the wireless system.
Alternatively, instead of an actual call, if a method of including a voice synthesis signal having a preset content from the mobile communication terminal Mo side or a place name or time at that time in the return signal, the operation of the mobile communication terminal Mo is performed. It is possible to reduce the burden on the person.

Note that the transmission / reception of signals between the base station apparatus St and the mobile communication terminal Mo when performing the radio wave condition measurement as described above is performed, for example, as shown in FIG. In response to the transmission of the signal 1, from the mobile communication terminal Mo, in addition to the location information, a response signal 2 corresponding to a normal communication purpose such as shipper, destination, daily work information such as movement route information of the day, and the like Subsequent radio wave condition measurement data (field strength data and error correction bit number) 3 is transmitted.
Regarding the error correction bit number detection processing at this time, since error correction processing is usually added in digital wireless communication, and error correction processing is performed in both the mobile communication terminal Mo and the base station device St. In many cases, a new process cannot be added if the process result is used.
If the error correction process is performed only in the base station device St, the data may be modified so that the data is acquired by the base station device St. In addition, when calculating the error bit rate, it is possible to independently perform the radio wave condition measurement without using the processing originally performed in the wireless system to be used. It is also possible to use the frame sync word used. As is well known, in digital communication, a synchronization signal having a specific signal arrangement pattern that is relatively easy to detect is arranged and transmitted at a predetermined position of each frame. On the receiver side, the frame synchronization word in the detection output signal is transmitted. Therefore, it is efficient to detect the frame synchronization word and calculate the error bit rate.

FIG. 4 is a flowchart showing a control example of the radio wave condition management apparatus using the radio wave condition measurement data collected as described above. In FIG. 4, when receiving a consultation about introduction of a wireless system from a customer (S10), after a general system explanation to the user (S11), specifying a use area desired by the user (S12), portable or in-vehicle The wireless communication system including the setting of transmission power, such as whether it is a type or another wireless device, is selected (S13). The user use area information of S12 and the selection information of the wireless communication system of S13 are transmitted to a management database recording various radio wave condition measurement data (S14), and the corresponding data is read (S15) and displayed on the display. It is displayed (S16). At this time, if the data is edited according to various situations such as season, time zone, rainy weather, fine weather, etc., the radio wave situation that can be placed in the situation according to the user's wish can be displayed.
Furthermore, as described above, if the actual call voice is stored, the call voice at that position is reproduced and output from the speaker in accordance with the movement of the pointer that displays the position on the map. It will be possible to experience a demonstration close to the actual feeling of use.

If the user desires a demonstration in another wireless communication system or a different area, the wireless system is changed (S17, Yes), and the process returns to S12 to specify a new usage area (S12). Then, the wireless system having different transmission power is selected (S13), and the same processing is repeated.
According to such a method, it is possible to grasp the radio wave condition closer to the actual feeling of use.
It will be even more convenient if data measured by various wireless communication systems constructed in various parts of the country can be collected as radio wave status management data. For example, mobile phone communication networks as disclosed in Patent Document 2, radio wave state measurement data in MCA (multi-channel access) systems nationwide, personal radio systems, amateur radio systems, fire fighting radios, etc. If the data is converted into a common format and made available to each other, it will be possible to meet the needs of users throughout the country.

The present invention is not limited to the example described above, and various modifications can be made.
For example, the radio wave condition measurement data on the mobile communication terminal Mo side can be stored in the memory of the mobile communication terminal Mo instead of returning to the base station device St side each time, and the accumulated data can be collected at a later date. As a collection method at a later date, a method of collecting the removable memory of the mobile communication terminal Mo, or a method of collecting by polling from the base station apparatus St at a required time after the end of the business hours can be considered.
Conversely, electric field strength measurement and error correction detection may be performed in the base station apparatus St. At this time, if transmission power information from the mobile communication terminal Mo is necessary, the transmission power information is added from the mobile communication terminal Mo and transmitted. Alternatively, when the transmission power of the mobile communication terminal Mo is fixed, the mobile communication terminal Mo identification information is transmitted, and the base station apparatus St moves based on the data table stored in association with the terminal identification information and the transmission power information. You may make it know the transmission power information of the communication terminal Mo. Since the mobile communication terminal Mo identification information is usually managed in some form, it is often unnecessary to add it.

Note that it is not necessary to limit the normal radio communication (communication intended by the radio system) to the above-described radio wave condition measurement, and the radio wave condition measurement required signal is transmitted from the base station device St as necessary. When the signal is received, the necessary measurement data may be added to the normal communication data and transmitted. Moreover, after transmitting a radio wave condition measurement request signal, it is possible to return or store the radio wave condition measurement data for a fixed time or until a release signal is transmitted.
Furthermore, if the mobile communication terminal Mo has the location information of its own station by providing GPS in the mobile communication terminal Mo or location detecting means by the location registration function to the cell base station of the cellular radio system, the base station device St It is also possible to transmit the instruction signal so as to return the radio wave condition measurement information for the mobile communication terminal Mo located in a specific range. That is, in the method described above, each mobile communication terminal is specified from the base station apparatus St and polling processing is performed. However, the mobile communication terminal requests information for returning a response signal with information specifying a specific position range. In Mo, position information that is always maintained by the local station or position information that is acquired when a request signal is received, and when they match, radio status information, local station identification information, and accurate position information are returned. .

By programming the radio wave condition measuring method and the radio wave condition management apparatus control method according to the present invention in accordance with an OS controllable by a computer, any computer equipped with the OS can be controlled by the same processing method. If the program is recorded on a recording medium in a computer-readable format, the program can be operated anywhere by carrying the recording medium.
As a recording medium for storing the program, a semiconductor medium (for example, ROM, nonvolatile memory card, etc.), an optical medium (for example, DVD, MO, MD, CD, etc.), a magnetic medium (for example, magnetic tape, flexible disk, etc.) In addition, the functions of the above-described embodiments are realized not only by executing the loaded program, but with the operating system or other application programs based on the instructions of the program. The case where the functions of the above-described embodiment are realized by jointly processing is also included.
