Description

  The present invention relates to a radio wave environment information processing server for notifying a radio wave environment of a region to which a mobile terminal is moved, such as a mobile phone, a PHS, a PDA device having a radio communication function, a personal computer device having a radio communication function, and the like. The present invention relates to a terminal, a radio wave environment notification system, and a radio wave environment notification method.

  Conventionally, when using a mobile terminal equipped with a communication function such as a mobile phone, a PHS, or a PDA device, the user can grasp the current radio wave environment on the spot by displaying the received radio wave intensity. In the middle of the period, it was impossible to know the radio wave environment after a predetermined time such as 5 minutes later.

  In recent years, mobile communication devices that can display non-communication areas such as out-of-service areas and areas with low radio wave intensity have been developed (see, for example, Patent Document 1). In this mobile communication device, communicable area data that can distinguish a place where communication is impossible depending on the existence of a tunnel or a building and geographical conditions is stored in advance in the information center on the device or on the communication network. The map data is referred to from the position, and the communicable area and the incommunicable area are distinguished and displayed on the map.

In addition, in the mobile communication device disclosed in Patent Document 1, the incommunicable area for each carrier (for example, for each telephone company and each type of mobile phone) is displayed by color, and the user can visually check the area. It can be confirmed whether or not the mobile terminal to be used can communicate.
JP 2000-295562 A

  However, in the mobile communication device disclosed in Patent Document 1 described above, the communication impossible area of each carrier is determined without determining the carrier used by the user (such as the carrier or the model of the mobile terminal). Since the color-coded display is performed collectively and the user visually confirms whether the mobile terminal used by the user can communicate or not, there is a problem that the visual judgment is complicated and lacks practicality.

  Moreover, in the mobile communication device disclosed in Patent Document 1 described above, since the communication impossible area data of each carrier is displayed collectively, the amount of data is excessive and stored in the own device. Therefore, it is necessary to increase the size of the storage device for that purpose, and when receiving distribution from an information center on a communication network, there is a risk of increasing the communication load consumed for sending and receiving the data. On the other hand, downsizing of portable terminals in recent years is required, and as described above, it is difficult to implement the functions that lead to an increase in the size of the device and an increase in communication load.

  The present invention has been made in view of the above points. A radio wave environment information processing server, a portable terminal, and the like that can notify a user of a future radio wave environment without increasing the size of the apparatus and increasing the communication load. An object is to provide a radio wave environment notification system and a radio wave environment notification method.

  In the radio wave environment information processing server, the terminal information acquisition unit acquires the current location information of the mobile terminal and the terminal information of the mobile terminal continuously or intermittently, and the terminal determination unit acquires the terminal information. Based on the terminal information acquired by the means, the radio wave environment database is referenced to determine the model of the portable terminal and the communication carrier to which the model belongs.

  The terminal movement calculation unit calculates a moving speed and a moving direction of the mobile terminal based on the history of the current position information acquired by the terminal information acquisition unit.

  And the said prediction information generation part reaches | attains the area where the said portable terminal moves in the future based on the calculation result of the moving speed and moving direction of the said portable terminal calculated by the said terminal movement calculation part, and this area And the radio wave reception intensity corresponding to the mobile terminal model and the communication carrier determined by the terminal determination unit in the area where the movement is predicted is detected from the radio wave environment database. Then, at least information indicating the time required to reach the area and information indicating the radio wave reception intensity in the area are transmitted to the mobile terminal.

  The portable terminal has its own device position detecting means, a transmitting unit, a receiving unit, and a notifying device, and the terminal information of its own device is continuously or intermittently transmitted along with the information on its own device position via the transmitting unit. By transmitting to the radio wave environment information processing server, information indicating the time required to reach the area and information indicating the radio wave reception intensity in the area transmitted from the radio wave environment information processing server is received by the receiving unit. Then, the notification means receives information received by the receiving unit, indicating the time required to reach the area, and information indicating the radio wave reception intensity in the area (for example, display display or voice) Output).

  According to the present invention, since the radio wave reception intensity corresponding to the model of the mobile terminal and the communication carrier in the area where the mobile terminal will move in the future can be notified, it is more accurate for the user. Future radio wave environment information can be provided.

  Further, according to the present invention, it is possible to avoid the inconvenience that unnecessary data such as data related to other communication carriers is transmitted and received between the radio wave environment information processing server and the portable terminal. The communication load can be reduced, and inconvenience of unnecessary data processing and unnecessary data display on the portable terminal side can be prevented, and the amount of calculation processing on the portable terminal side and the information display can be reduced. Simplification can be achieved.

  According to the present invention, the terminal information including the location information of the own device, the current time information in the own device, and the terminal type information related to the type of the own device is transmitted from the mobile terminal, To calculate the time required to reach the distribution of radio wave reception intensity with reference to the radio wave environment database held for each model of mobile terminal and each carrier, only the information for each carrier is transmitted and received. Without causing an increase in size or communication load, it is possible to provide a user with a simple radio wave environment in the area where the mobile terminal will move in the future.

(Radio wave environment notification method using radio wave environment alarm system)
The radio wave environment notification method using the radio wave environment notification system having the above configuration is performed according to the following procedure. 4 and 5 are flowcharts showing processing operations in the user and each device in the radio wave environment notification method according to the present embodiment.

  First, at the start of processing, as shown in FIG. 4, a destination is set by a user operation on the mobile terminal 1 (S101). When the destination is set by the user (S201), the portable terminal 1 acquires current position information by GPS and time information by a clock function (S202), connects to the base station 2 (S203), Terminal information including position information, current time information, and terminal type information is transmitted (S204). The base station 2 receives the destination information, location information, current time information, and terminal type information transmitted from the mobile terminal 1 (S301), and the radio wave environment information connected to the Internet 4 via the public line network 3 The information is transferred to the processing server 5 (S302).

  The radio wave environment information processing server 5 receives the destination information, the position information, the current time information, and the terminal type information transferred from the base station 2 (S401). The terminal movement calculation unit 55 and the movement route search unit 56 The travel route search and travel speed of the terminal 1 are calculated (S402). Next, the radio wave environment information processing server 5 calls the radio wave environment information correlated with the position information (map information) stored in the radio wave environment database 8 in advance (S403), and the movement route searched by the movement route search unit 56 The predicted arrival time to the upper out-of-service area or the service area is calculated by the prediction information generation unit 57 (S404).

  Thereafter, the radio wave environment information processing server 5 transmits the prediction result by the prediction information generation unit 57 to the base station 2 as prediction information (S405), and the prediction result is transmitted through the user management unit 54 together with the terminal information D1 to D4. The information is stored in the user history database 6 (S406), and the processing of the radio wave environment information processing server 5 is terminated.

  On the other hand, the base station 2 receives the prediction information transmitted from the radio wave environment information processing server 5 (S303), transfers it to the portable terminal 1 (S304), and ends the processing of the base station 2. The mobile terminal 1 receives the prediction information transmitted from the base station 2 (S205), notifies the user of the prediction result using output display means such as a display display or an alarm (S2206), and the processing by the mobile terminal 1 Exit.

  Next, the processing operation while the terminal is moving will be described. It is assumed that the destination has already been set by the user while the terminal is moving, and the radio wave environment information processing server 5 is in a state where the initial route search has been completed.

  First, as shown in FIG. 5, the portable terminal 1 automatically acquires current position information and time information by GPS, similarly to steps S202 to S204 described above (S501), and uses these information as terminal information in the radio wave environment. The information is transmitted to the information processing server 5 and the terminal process is terminated. The radio wave environment information processing server 5 calls a record in the user history database 6 already stored based on the terminal information (S601), and obtains the route search result and the current position information already stored in the user history database 6. In comparison, it is confirmed whether the terminal is moving along the searched route (S602), it is determined whether route correction is necessary (S603), and when it is determined that route correction is necessary (in step S603). "YES"), the above-described step S402 is executed, and the movement route of the portable terminal 1 is corrected (S604).

  If it is determined in step S603 that route correction is unnecessary ("NO" in step S603), the radio wave environment database 8 is searched to determine whether there is an incommunicable region such as an out-of-service area on the route. In step S605, if it is determined that there is no area where communication is not possible ("NO" in step S605), the server side processing is terminated.

  If it is determined that there is an incommunicable area ("YES" in step S605), the estimated arrival time to the incommunicable area on the movement route and the required estimated time to the subsequent communicable area are calculated (S606). ), The calculation result is transmitted to the portable terminal 1 side as prediction information (S607), and the server side processing is terminated.

  Upon receiving the prediction information, the mobile terminal 1 notifies the user by displaying the radio wave environment on the mobile terminal display 1a as shown in FIG. 6 or sounding an alarm as shown in FIG. 7 (S502). The process is terminated. In this embodiment, when it is determined that the mobile terminal 1 enters the out-of-service area, the power supplied from the RF circuit of the mobile terminal 1 is turned ON / OFF or shifted to the power-down mode.

(Operational effects of this embodiment)

  In the present embodiment, the user's destination is acquired from the mobile terminal 1 side, and the user searches the travel route of the mobile terminal 1 by referring to the map database 7 from the user's location information and the destination. The time required for actual movement can be predicted more accurately. As a result, according to the present embodiment, for example, by sending information such as entering the out-of-service area 5 minutes later to a user who is creating a mail by boarding the Shinkansen, the user can speed up the mail creation It is possible to take measures such as preparing a transmission standby state in advance. In addition, since it is possible to obtain information that the user enters the area within a few minutes after entering the out-of-service area, an e-mail creation schedule in the out-of-service area can be established. Furthermore, after setting the destination, there is no burden on the user and the service can be used easily. In addition, by adding a setting function such as sounding an alarm several minutes ago, it is possible to make a notification in accordance with the user's mail creation pace or the like.

  Further, in this embodiment, when the mobile terminal 1 determines that the mobile terminal 1 enters an out-of-service area, the mobile terminal 1 turns on or off the power supplied by the RF circuit of the mobile terminal 1 or shifts to the low power mode, thereby preventing communication. Unnecessary radio wave transmission / reception can be suppressed in the possible area, and battery saving is possible.

(Example of change)
In the present embodiment, the location information and the current time of the mobile terminal 1 are acquired by the GPS function on the mobile terminal 1 side, and these are transmitted to the radio wave environment information processing server 5 as terminal information. For example, the position of the mobile terminal 1 may be searched for on the base station 2 or the radio wave environment information processing server 5 side.

  In this embodiment, the travel route of the user is searched from the map database 7 and the required arrival time according to the travel route is predicted. You may make it perform prediction by distance. In this case, for example, when the user is moving on a straight line such as a railway at a constant speed, the prediction calculation process can be simplified, the processing load on the server side is reduced, and the response speed is increased. Can be achieved.
