  The present invention relates to a mobile communication field strength positioning system and a mobile communication terminal used therefor.

Conventionally, as this type of mobile communication field strength positioning system, there is one described in Japanese Patent Laid-Open No. 6-350516 (Patent Document 1). In this publication, a method of measuring electric field strength by mounting a field strength measuring device having GPS on a vehicle or the like and displaying it on a map is adopted.
JP-A-6-350516 (paragraphs 0007 to 0010)

  The first problem is that the equipment cost, personnel cost, moving cost, etc. required for the mobile communication carrier to measure the electric field strength are high. The reason is that it is necessary to purchase equipment for measuring the electric field strength, hire a person for measuring the electric field intensity, and go to a place where the electric field intensity measurer measures the electric field intensity.

  The second problem is that the mobile communication service provider cannot grasp where the mobile communication user wants to use the mobile communication terminal. The reason for this is that when the field strength measurer performs measurement, the field strength measurer estimates the location where the mobile communication user wants to use the mobile communication terminal and makes a declaration from the user. This is because measurement cannot be performed from the standpoint of an unreported user.

  The third problem is that when a mobile communication carrier installs a base station for mobile communication, how many users want to use the mobile communication terminal at the place where the base station is installed, It is impossible to grasp. The reason for this is that it is possible to specify the location where you wish to use the mobile communication terminal by making a declaration such as a telephone call from the user, but the person who makes the declaration is a part of the person, and who wants to This is because it is not possible to judge whether it is a degree.

  The fourth problem is that when a user selects a mobile communication carrier, the state of electric field strength at a place where the user desires to use the mobile communication terminal cannot be grasped. The reason is that the mobile carrier has disclosed the coverage area of the base station, but it is the ideal coverage area calculated from the installation location of the base station, so the electric field strength at the place where you want to use the mobile communications terminal This is because the state cannot be determined until the mobile communication terminal is used.

  An object of the present invention is to provide a mobile communication electric field strength positioning system capable of solving problems such as equipment costs, labor costs, and movement costs for the mobile communication operator to measure electric field strength, and the like. It is to provide a mobile communication terminal.

The mobile communication field strength positioning system of the present invention includes a mobile communication terminal and a totaling unit that collects position information and electric field strength information transmitted from the mobile communication terminal, and the totaling unit includes the mobile unit It is characterized by counting position information when a body communication terminal tries to make a call outside the service area .

The mobile communication terminal of the present invention comprises a position measuring means for measuring a position, an electric field strength measuring means for measuring electric field strength, and a memory means for storing measurement results of the position measuring means and the electric field strength measuring means. In the mobile communication terminal having, when the mobile communication terminal tries to make a call outside the service area, the position information measured by the position measurement unit is stored in the memory unit, It is characterized by transmitting information .

  The first effect is that the equipment cost, labor cost, moving cost, etc. for the mobile telecommunications carrier to measure the electric field strength can be reduced. The reason is that, since the electric field strength is measured using the mobile communication terminal of the user who uses the mobile communication, the moving cost to the measuring device, the human resource, and the measurement place is not required.

  The second effect is that a mobile communication carrier can grasp where a mobile communication user wants to use a mobile communication terminal. The reason is that a user of mobile communication can confirm information on a place where the user wants to use the mobile communication terminal at the center.

  The third effect is that when a mobile communication carrier installs a mobile communication base station, it is possible to grasp how many users wish to use mobile communication at the location where the base station is newly installed. It is in. The reason is that the user of the mobile communication aggregates information on the location where the user wishes to use the mobile communication terminal at the center.

  The fourth effect is that when the user selects a mobile communication carrier, the state of the electric field strength at a place where the mobile communication user desires to use the mobile communication terminal can be grasped. The reason is that a user who wishes to purchase a mobile communication terminal can grasp the electric field strength at a place where the user wants to use the mobile communication terminal before purchasing the mobile communication terminal.

  The fifth effect is that the user automatically collects the position information and the electric field intensity information without measuring the trigger of the measurement by measuring the position and the electric field intensity when the user measures the position. In addition, if the user is out of the service area when the position is measured, the position information and the electric field strength information are transmitted after the user is in the service area, so that information outside the service area can also be collected.

  In addition, by measuring the position when a user tries to make a call outside the service area, and transmitting after the user has entered the service area, the number of people who want to use the service outside the service area can be counted. I understand the situation. In addition, if a specific signal is transmitted from the base station and the mobile communication terminal that has received the specific signal measures the position and the electric field strength, it is possible to collect information on the specific area.

  Next, the best mode for carrying out the invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a mobile communication field strength communication system according to the present invention.

  In FIG. 1, reference numeral 121 denotes a mobile communication terminal that measures electric field strength and position information, accumulates them in a memory unit, and sends out the accumulated electric field strength and position information at a specific timing. The mobile communication terminal 121 is a mobile phone or the like having a position measuring function and an electric field strength measuring function by a GPS system. Since a general mobile phone has an electric field strength measurement function, the function may be used as it is, or if importance is placed on accuracy, a new electric field strength measuring device with high measurement accuracy may be provided.

  111 is a base station that receives electric field strength information and position information from the mobile communication terminal 121, and 101 is a center that receives electric field strength information and position information from the mobile communication terminal 121 from the base station 111. The base station 111 has a function of receiving the above-described electric field strength information and position information from the mobile communication terminal 121 such as a mobile phone, and a function of transmitting such information to the center 101. The center 101 is a center server having a function of totaling position information and electric field intensity information received from the base station 111 by program control, a function of creating an electric field intensity distribution on a map, and the like.

  FIG. 2 is a block diagram illustrating a configuration example of the mobile communication terminal 121. In the figure, reference numeral 216 denotes a display unit for displaying various data, and the user performs display or the like for confirming whether the mobile communication terminal 121 is within or outside the service area. Reference numeral 217 denotes a button unit operated by the user, and 212 denotes a GPS module unit that receives a signal from a GPS satellite and calculates a position.

  214 is an electrometer strength measuring unit that measures the electric field strength, 213 is a GPS module unit 212, an accumulation timing monitoring unit that determines the timing for accumulating position information and electric field strength information from the electric field strength measuring unit 214, and 215 is an accumulation timing monitoring unit It is a memory unit that stores position information and electric field strength information from the GPS module unit 212 and the electric field strength measuring unit 214 at the timing output from 213. As the electric field strength measuring unit 214, an existing measuring means possessed by the mobile communication terminal as described above may be used, or an electric field strength measuring device with high measurement accuracy may be provided.

  Reference numeral 218 denotes an antenna unit that transmits position information and electric field strength information from the memory unit 215 to the center 101 at a specific timing. A control unit 211 controls each part of the terminal such as the display unit 216, the button unit 217, the GPS module unit 212, the meter strength measurement unit 214, the accumulation timing monitoring unit 213, the memory unit 215, and the antenna unit 218.

  Next, the operation of this embodiment will be described. First, the operation of the mobile communication terminal 121 in FIG. 2 will be described. Normally, when using the mobile communication terminal 121, the user checks the display unit 216 in order to check whether the mobile communication terminal 121 is within or outside the service area. At this time, if the display on the display unit 216 is turned off, the button unit 217 is operated to display the display unit 216. Alternatively, the user may arbitrarily operate the button unit 217. At this time, it is assumed that the mobile communication terminal 121 is within range.

  Next, when confirming the current position, the user confirms the position by operating the button unit 217. At this time, when the accumulation timing monitoring unit 213 receives a position measurement instruction from the button unit 217, the accumulation timing monitoring unit 213 transmits an accumulation timing signal to the control unit 211. The control unit 211 reads position information from the GPS module unit 212 based on a signal from the accumulation timing monitoring unit 213 and accumulates it in the memory unit 215. This position information is position information obtained by analyzing latitude and longitude based on the received information from GPS hygiene by the GPS module 212.

  The GPS position information may be information converted into position information such as latitude / longitude (information converted into position information such as latitude / longitude by the GPS module unit 212), or information from a GPS satellite received by the GPS module 212 itself. When using the information from the GPS satellite itself, the mobile communication terminal 121 does not need to perform position analysis, and the center 101 may have a position analysis function.

  Further, when measuring the position information, the control unit 211 reads out the electric field strength information measured by the electric field strength measurement unit 214 and accumulates it in the memory unit 215. The control unit 211 transmits the position information accumulated in the memory unit 215 and the electric field strength information at the position via the antenna unit 218 with a predetermined timing signal. The base station 111 receives the transmitted position information and electric field strength information and transmits them to the center 101.

  On the other hand, when the user performs position measurement, if the mobile communication terminal 121 is out of the service area, the control unit 211 similarly reads position information and field strength information from the GPS module 212 and the field strength measurement unit 214. The measurement results are stored in the memory unit 215. At that time, when the measurement is performed at a plurality of positions outside the service area, the position information and the electric field strength information at the place are sequentially stored in the memory unit 215.

  The control unit 211 monitors whether it is within or outside of the service area, and when it is within the service area, reads the position information and the electric field strength information stored in the memory unit 215 and transmits them via the antenna unit 218. The base station 111 receives the transmitted position information and electric field strength information and transmits them to the center 101. As described above, even when the mobile communication terminal 121 is out of the service area, it is possible to collect out-of-service information by measuring the position and the electric field strength.

  When the user tries to make a call outside the service area, the control unit 211 reads position information and electric field strength information from the GPS module unit 212 and the electric field strength measurement unit 214 and stores the measurement results in the memory unit 215. . The control unit 211 transmits the position information and the electric field strength information accumulated in the memory unit 215 after entering the area. The base station 111 receives the transmitted position information and electric field strength information and transmits them to the center 101. In this case, the center 101 counts the transmitted information. As a result, the number of people who want to use the mobile communication terminal 121 outside the service area is known.

  In this case, the electric field strength need not be measured, and only the position may be measured and transmitted. Further, when transmitting information from the mobile communication terminal 121, it is preferable to add identification information indicating that it is information when attempting to make a call outside the service area, and to classify and count by the identification information on the center 101 side. .

  Here, in order to reduce the storage capacity of the memory unit 215, the electric field intensity value and the position information may be written into the memory unit 215 only when the electric field intensity value is smaller than a specific set value. The mobile communication terminal 121 transmits the electric field strength value and position information as a method of transmitting immediately after measurement (in the case of within a range), and determines the transmission timing of the mobile communication terminal 121 to transmit. There are various methods such as a method, a transmission method according to an instruction from the base station 111, a transmission method according to an instruction from the center 101, and a method in which a user of the mobile communication terminal 121 arbitrarily transmits.

  In addition, when measuring the position and electric field strength, the measurement is performed when the user measures the position as described above, so that the user can automatically detect the position information and its position without worrying about the trigger of the measurement. It becomes possible to measure the electric field strength at the place. In addition, a specific signal may be transmitted from the base station 111 based on the control of the center 101, and the mobile communication terminal that has received the signal may measure the position and electric field strength and transmit the measured signal to the base station 111. This makes it possible to collect information on a specific area.

  Next, when the electric field strength value and the position information are transmitted from the base station 111 as described above, the center 101 sequentially stores the transmitted electric field strength value and the position information in a storage means (not shown) and receives a plurality of movements. Electric field strength values and position information from the body communication terminal 121 are accumulated. The center 101 performs processing such as summing up the position information and electric field intensity values accumulated in the storage means and creating a meter intensity distribution on the map. It is assumed that the map data is stored in a map database (not shown). Further, the center 101 can know the desired use situation of the mobile communication terminal outside the service area by counting the position information measured when trying to make a call outside the service area as described above.

  Instead of the center 101 indicating the electric field strength on the map, a place where the electric field strength is lower than the preset strength may be indicated on the map, or the user of the mobile communication terminal 121 A place where is greater than or equal to a predetermined value may be indicated on the map. In addition, it is also possible for the user of the mobile communication terminal 121 to indicate on the map a place where the electric field intensity is less than a predetermined value and the user of the mobile communication terminal 121 has a predetermined value or more. Further, it is possible to count the number of users in the cover area for each base station.

  In this embodiment, by measuring the position and the electric field intensity when the user measures the position by GPS, the user automatically collects the position information and the electric field intensity information without worrying about the measurement trigger. be able to. Further, if the GPS measurement is out of the service area, the position information and the electric field strength information can be transmitted after the service area has been acquired, thereby collecting information outside the service area.

  In addition, GPS measurement is performed when a user tries to make a call outside the service area, and transmission is performed after the user is within the service area, so that the number of people who want to use the service outside the service area can be counted. I understand the situation. In addition, if a specific signal is transmitted from the base station and the mobile communication terminal that has received the specific signal measures the position and the electric field strength, it is possible to collect information on the specific area.

  INDUSTRIAL APPLICABILITY The present invention can be used as information when planning a base station installation of a mobile communication terminal. This is because it is possible to grasp how many people are using the mobile communication terminal in a location outside the service area of mobile communication, so that the base station can be installed efficiently.

  The present invention can also be utilized when a person who desires to purchase a mobile communication terminal selects a mobile communication terminal operator. This is because when a person who wants to purchase a mobile communication terminal selects a mobile communication terminal provider, the electric field strength at the place where the mobile communication terminal is desired can be determined before purchasing the mobile communication terminal. Because.

It is a block diagram which shows one Embodiment of the system which concerns on this invention. It is a block diagram which shows an example of the mobile communication terminal of FIG.
