  Next, each unit (communication unit 31, recording unit 33, control unit 35) of the location information server 30 will be described.

  The communication unit 31 of the location information server 30 communicates with each of the mobile terminals (the 51st mobile terminal M51 to the 55th mobile terminal M55) registered in the location information database D1, and provides disaster information to these mobile terminals. Before the transmission, the position information of each portable terminal is acquired every second time T2 (for example, 30 minutes).

  For example, the form which transmits a positional information to the communication part 31 of the positional information server 30 for every 2nd time T2 using the positional information program installed in each portable terminal can be considered.

  In addition, the communication unit 31 of the location information server 30 is a base station that forms a radio link with a mobile terminal in a communication carrier, a mobile switch that performs routing (selection of communication route), call setup / disconnection, billing, etc. MSC (Mobile Switching Center), VLR (Visitor Location Register) which is a location registration database for each area covered by the mobile switch, Gateway Switch (GMSC), mobile phone number and identification information of the mobile terminal (IMEI) A form for acquiring location information of each mobile terminal by communicating with any of HLR (Home Location Register) which is a database for managing user information such as terminal identification number, SIMCID such as ICCID) and location information Can be considered.

When acquiring the position information of each mobile terminal, the detailed level of position information that can be acquired is acquired without limiting the degree of detail of the position information, and this is recorded in the position information database D1.
However, when disclosing location information of the mobile terminal or another mobile terminal (second mobile terminal) to the mobile terminal (first mobile terminal), the “position information to be disclosed” set by the user of the mobile terminal is disclosed. Based on the level of detail (first level of detail parameter dp1, second level of detail parameter dp2), the level of detail of the position information is adjusted.

  In addition, the communication unit 31 of the location information server 30 receives the disaster information from the information source transmission unit 20 and receives the disaster information (or after the disaster information is input by the input / output terminal 70). Based on the database D1 and the group information database D2, the disaster information and the like are transmitted to the mobile terminals (the 51st mobile terminal M51 to the 55th mobile terminal M55), and the safety response information from the mobile terminal is received.

  The recording unit 33 of the position information server 30 records the position information database D1 and the group information database D2.

The position information database D1 indicates a relationship among information related to a user of the mobile terminal, a mobile terminal (mobile terminal name), information related to the position of the mobile terminal, and information related to safety transmitted from the mobile terminal.
The information regarding the user of the mobile terminal in the position information database D1 is information input by the user via each mobile terminal (information set by the user setting operation), and the user name corresponding to each mobile terminal, It has a user ID (an identification number for logging in to the location information program) and a user mark (may be a photo).
The user name may be in a form in which a different name is used for each group, such as a user name corresponding to the user ID: 11: Papa and Taro.

  The information related to the position of the mobile terminal is information received from the mobile terminal such as an HLR, and includes latitude / longitude information corresponding to each mobile terminal, an area name corresponding to the latitude / longitude information, and a positioning date / time.

  The latitude / longitude information and the positioning date / time in the position information database D1 are the mobile terminals (the 51st mobile terminal M51 to the 55th mobile terminal) in which the communication unit 31 of the position information server 30 is registered in the position information database D1 every second time T2. M55) or by the communication unit 31 communicating with a base station or the like in a communication carrier.

  The area name corresponding to the latitude / longitude information in the position information database D1 is obtained by converting the latitude / longitude information of the mobile terminal into the area name using a table (not shown) for converting the latitude / longitude information into the area name.

  Information regarding safety in the location information database D1 is whether the communication unit 31 of the location information server 30 has received a safety response operation from the mobile terminals (the 51st mobile terminal M51 to the 55th mobile terminal M55) registered in the location information database D1. This is initialized when the first disaster information (disaster information of which the scale of disaster is large) is transmitted, and the parameter (safety type parameter sp) in the safety type column is used for all mobile terminals. It is set to an initial value (sp = 1) indicating that the safety of the person is unknown (the safety answer operation is not performed).

  After the initialization, the safety information in the location information database D1 is updated when the safety response information is received from the mobile terminal.

  When a specific operation for safety response (safety response operation) is performed by the user of the mobile terminal on the location information program installed in the mobile terminal, the value of the parameter in the safety type column is 0 (answer Is changed to the safety type parameter sp = 0) indicating that there has been. That is, the initial value of 1 is maintained in a state where a specific operation for safety response (safety response operation) is not performed.

The safety response operation is, for example, one of operations performed on the location information program installed in the mobile terminal. Specifically, the “safety” operation on the second interrupt screen Pi2 displayed as an interrupt on the first screen P1 is performed. The first operation of clicking the “Report” button 601 or the “safe” button 602, the second operation of clicking the “send message” button 603, inputting the message, and then clicking the second send button 605 Have
However, when the location information server 30 receives the cancellation information from the information source transmission unit 20, the safety type parameter sp of all users is changed to 0 regardless of the presence / absence of the safety response operation.

The group information database D2 shows a relationship between information about groups used in group chat (group message) in the position information program and information about users belonging to the group.
The information about the group is information input by the user via the portable terminal (information set by the group setting operation), and has a group name, a group ID (group identification number), and a group mark (may be a photograph). .
The information related to the users belonging to the group is information (information set by the position information disclosure designation operation) input by the user via the mobile terminal. The user name belonging to the group, the user ID belonging to the group, and the normal Detail level of position information disclosed at the time (while safety answer parameter sp is 0) (first detail parameter dp1), Detail level of position information disclosed at the time of disaster (while safety answer parameter sp is 1) (first 2 detail parameters dp2).

  In this embodiment, the first detail parameter dp1 and the second detail parameter dp2 disclose three levels (1: coarse position information (for example, the prefecture level)), medium roughness position information (for example, 3) disclosing (municipal level): 3: disclosing detailed position information (for example, disclosing address level) is described. However, it may be a form having two stages or four or more stages.

The second detail parameter dp2 is preferably set to a detail level that is the same as or more detailed than the first detail parameter dp1.
For example, the first detail parameter dp1 can be adjusted by the user in three stages, and the second detail parameter dp2 can be fixed at the finest detail.

In the present embodiment, the group name: Tanaka family (group ID: G001) is assigned to the user (user name: dad, first detail parameter dp1: 2, second detail parameter dp2: 3). ), User with user ID: 12 (user name: Hanako, first detail parameter dp1: 1, second detail parameter dp2: 3), user with user ID: 13 (user name: advance) , First detail parameter dp1: 2, second detail parameter dp2: 3) belongs.
In addition, group name: parents' house (group ID: G002), user ID: 23 (user name: grandpa, first detail parameter dp1: 3, second detail parameter dp2: 3), user User with ID: 24 (user name: grandma, first detail parameter dp1: 3, second detail parameter dp2: 3), user with user ID: 11 (user name: Taro, first detail Degree parameter dp1: 1, second detail parameter dp2: 3) belongs.

  The control unit 35 of the position information server 30 controls the communication unit 31 and the recording unit 33.

  Specifically, the control unit 35, when the location information server 30 receives disaster information from the information source transmission unit 20, the mobile terminal (the 51st mobile terminal) registered in the location information database D1 via the communication unit 31. The disaster information is transmitted to M51 to 55th portable terminal M55).

Moreover, the control part 35 may be a form which transmits the message containing 1st disaster information among disaster information to a portable terminal using emergency early warning mail, SMS, etc.
The mobile terminal does not display a message including the first disaster information when the position information program is activated, and displays a message including the first disaster information when the position information program is not activated. To do.
As the message including the first disaster information, for example, the content “Earthquake occurred” described in the area excluding the OK button 501a and the first mark ma1 in the second disaster information display area 501 in the first interrupt screen Pi1 in FIG. An earthquake early warning was received. An earthquake occurred in the Shikoku region at 08: 08-03: 08: 30: 17 The maximum predicted seismic intensity is 6: Magnitude: 7.1 Please ensure your safety. Conceivable.
Thereby, even when the position information program is not activated, the first disaster information can be transmitted to the user of the mobile terminal.

  In addition, the control unit 35 is configured so that the location information server 30 can use the user setting operation, the group setting operation, the location information disclosure specifying operation, and the like from the 51st mobile terminal M51 to the 55th mobile terminal M55 to When the information regarding the information or the information regarding the degree of detail of the position information to be disclosed is received, the position information database D1 and the group information database D2 recorded in the recording unit 33 are updated.

  Further, when the position information server 30 receives the position information of the 51st mobile terminal M51 to the 55th mobile terminal M55, the control unit 35 updates the position information in the position information database D1 recorded in the recording unit 33.

The control unit 35 is recorded in the recording unit 33 when the location information server 30 receives the safety response information from the 51st mobile terminal M51 to the 55th mobile terminal M55 based on the safety response operation by the user of the mobile terminal. The safety type parameter sp in the position information database D1 is updated.
When the 51st mobile terminal M51 to the 55th mobile terminal M55 transmit the safety response information to the location information server 30 based on the safety response operation, the positioning is performed and the location information is also transmitted.
Based on the transmitted position information, the position information in the position information database D1 is updated.
Note that when the safety response information is transmitted based on the safety response operation, the position information may not be transmitted.

In addition, the control unit 35 transmits the location information and safety information to the portable terminal of the user (person) who has logged into the location information program via the communication unit 31 based on the location information database D1 and the group information database D2. Information of another user (other person) belonging to the group to which the user (person) logged in to the position information program belongs is transmitted.
For example, a user (user name: daddy, Taro) with a user ID: 11 belongs to a group of group name: Tanaka family (group ID: G001) and a group name: family (group ID: G002). Therefore, users belonging to these groups (group name: Tanaka family (group ID: G001), user ID: 12 user, user ID: 13 user, group name: real family (group ID) : Position information and safety information of the user ID: 23 belonging to G002) and the user ID: 24) are transmitted to the 51st portable terminal M51 corresponding to the user ID: 11.

The position information transmitted from the position information server 30 to the mobile terminal uses the position information with the finest detail, and the degree of detail of the position information displayed on the mobile terminal is adjusted based on the safety information (safety type parameter sp). Is done.
Specifically, for a user whose safety type parameter sp is 0, the location information is displayed at the level of detail of the location information disclosed normally (first detail level parameter dp1), and the safety type parameter sp is 1 used. For the person, the position information is displayed at the detail level (second detail level parameter dp2) of the position information disclosed at the time of disaster.
However, at the stage of transmitting location information from the location information server 30 to each mobile terminal, further location information is disclosed for each mobile terminal to be transmitted based on the safety information (safety type parameter sp) recorded in the location information database D1. The position information may be transmitted to each mobile terminal in a state where the degree of detail is changed for each user.

Next, details of the position information program will be described.
The location information program includes a first screen P1 (disaster information, display of location information for each user), a second screen P2 (group chat display), a third screen P3 (disaster information list display), a fourth screen P4 (past (Detailed display of disaster information), a first interrupt screen Pi1 (disaster information interrupt display), and a second interrupt screen Pi2 (safety response interrupt display) are displayed on the mobile terminal.
During normal operation, any one of the first screen P1 to the fourth screen P4 is displayed on the mobile terminal by the user's operation. In the event of a disaster, the first screen P1 to the fourth screen P4 are displayed. The first interrupt screen Pi1 is displayed as an interrupt, and after a predetermined operation (clicking on the OK button 501a), the second interrupt screen Pi2 is displayed.

  The first screen P1 has a first disaster information display area 101, a first user position information display area 103, and a screen switching button display area 105 (FIGS. 4, 5, 8-11, 15, and 17). FIG. 21).
