FIG. 2 is a diagram showing a received data fetching process on the navigation system side of the present invention.

First, when moving in a group, the user having the navigation system 26 and the portable terminal 32 performs a group and user registration process for receiving this service with the server 18 shown in FIG.

A user desiring this service calls a specific number (# 1234 or the like) (step S00).
1). Upon receiving the request, the server 18 confirms with the user whether it is a new group registration (step S).
002). In the case of new, for example, "arbitrary alphanumeric characters 4
Please register the digit group ID "(step S003). Here, the service supply side can arbitrarily set the number form and the number of digits to be used as the group ID. The group ID is not limited to four-digit English / numerical characters.

The user who has received the guidance sends an arbitrary number of alphanumeric characters having the specified number of digits, which has been agreed between the users in the group (step S004). The server that has received the ID performs a search process in the database 20 and checks whether there is a duplication with another group ID (step S005). If there is an overlap, the process returns to step S003 to prompt for re-input of the group ID. If they do not overlap, registration of the display number within the group is prompted (step S006).

The user who has completed the group ID registration registers the display number in the group (step S00).
7). As for the display number, it is desirable to use a number from 01 to 10, but it is not limited thereto. The server 18 having received the registration number searches the database 20 and checks whether there is any duplication as in the group ID registration process (step S008). If there is an overlap, the process returns to step S006 to prompt for re-input. If they do not overlap, guidance is given to the effect that "registration is completed" (step S009), the line is disconnected, and the process is terminated (step S010).

FIG. 5 shows a registered data format in the database after registration. B01 is a registered group ID. In B02, the display number and telephone number of each user in the B01 group are registered. B03
, The position information of each user at time B04 is registered.

Next, a processing flow from when the navigation system 26 of each user receives radio waves from the GPS satellites 22 and requests registration of its own position information to the server 18 will be described with reference to FIG.

The navigation system 26 receives a GPS radio wave (step S100). The navigation system 26 displays its own position on the monitor 28 (step S101). The received position information is stored in the data storage unit 38 (Step S102). The control unit 36 determines whether or not the own position data output period for reading data from the control unit 36 and transmitting data to the externally connected portable terminal 32 has been reached at regular intervals (step S103). ). If it is determined that the period has not been reached, the process returns to step S100. If the period has been reached, a call processing request is made to the external terminal data transmitting / receiving unit 40 (step S104). Control unit 36
Sends its own position data to the server 18 (step S105). The control unit 36 disconnects the line and ends the processing (step S106).

FIG. 4 shows the format of a message sent from the portable terminal 32 to the server 18.
A01 is a group ID registered in the database 20, and A02 stores a display number, a telephone number, and the like registered by each user at the time of group registration. A03 is time A04
, And stores latitude / longitude information. Then, the time at the time of the last GPS reception and the end flag indicating the end of the data are stored.

Next, a data registration processing flow on the server side when data is sent from the user as described above will be described with reference to FIG.

When there is a data registration request from the user, the server 18 first prompts for a group ID as a group ID confirmation process (step S201). Server 18
Searches the database 20 for the input group ID and determines whether the group ID is registered (step S202). If the result of the determination is that the group ID has been registered, confirmation of the user display number within the group is started (step S203). It is determined whether the in-group display number is registered (step S204). If the result of determination is that a group ID has been registered, data accumulation processing is performed (step S20).
5), end the processing.

If the result of determination in step S202 is that the group ID has not been registered, an "age not registered" ID message is sent to the user (step S206). Further, the server 18 sends a message “Do you want to perform registration processing?” And determines whether or not to perform new ID registration processing based on an input from the user (step S207). The user confirms the message displayed on the monitor 28 via the mobile terminal 32, and selects a process. When the server 18 newly registers as a result of the determination, the server 18 proceeds to the process of step S003 in FIG. If registration is not performed as a result of the determination, an end process is performed on the server 18.

If the result of determination in step S204 is that the user display number has been registered, data accumulation processing is performed on the database 20 in the format as shown in FIG. In other words, if the user display number has not been registered, a message "display number is not registered" is sent to the user as in the group ID registration process (step S208). The server 18 determines whether to perform a registration process (step S20).
9). If the result of determination is that registration processing is to be performed, the process proceeds to step S006 in FIG. If not, an end process is performed.

Next, a flow of sending the registered group position information data from the server 18 to the user will be described with reference to FIG.

The server 18 monitors a data transmission cycle for each group ID for transmitting data at a certain fixed cycle. First, a confirmation process is performed to determine whether or not the group ID: ○ has reached the transmission period, and it is determined whether or not the transmission period has reached (step S300). As a result of the judgment,
If not, the process is performed for each group ID (step S301). As a result of the determination, if the transmission cycle has been reached for each group ID, the server 18 performs a data fetch process in the group ID that has reached the transmission cycle in the database (step S302). The server 18
The user display number and the telephone number of the user are obtained from the captured data (step S
303), edit processing to the transmission data format 2 in FIG. 4 is performed, and data is transmitted to the MGS 10 (step S304).

Further, the MGS 10 reads out the destination telephone number stored in A05 and performs data transmission processing for each user. Here, in FIG.
Reference numeral 05 denotes telephone numbers of all users registered in the group and header information attached to the MGS 10 for processing. From A06, ID information (user display number, telephone number, etc.) of each user, time A07 And A1
1, location information of users A and B is stored,
Finally, an end flag indicating the end of the data is stored.

Finally, the reception data fetching process on the navigation system side will be described with reference to FIG.

Control unit 36 of navigation system 26
Is monitoring the period of the received data at an arbitrary fixed period, and determines whether or not the reception period has been reached (step S400). If it is determined that the period has not been reached, the process waits until the period is reached. If the result of the determination is that the period has been reached, data fetch processing is performed (step S401). Each user of the received data determines whether or not the user is on the current map (step S402). If there is no result of the determination, the display waits (step S404).
If there is a result of the determination, a mark is displayed on the map (step S403), and the process ends.

Here, it is assumed that the received data has already been stored in the portable terminal, and the portable terminal has overwritten and saved the data from the server 18 each time it was received. Next, the control unit performs an analysis process based on the acquired data, and performs a display process when the user of the received data is present on the map where the current position is displayed. If it is not on the map, a standby process is performed, and when it reaches the current map, a display process is performed.

Here, FIGS. 6 and 7 show images displayed on a map when the display is performed. FIG. 6 shows the case where the display is completed, but (28a), (28b),
The display mark is changed as in (28c) and displayed together with the user display number registered first. Also, as shown in FIG.
By selecting a mark on the map, it is also possible to display the telephone number and name of the displayed user.

As described above, the present invention has been specially described in the case where the navigation system mounted on the car and the portable terminal are used. However, recently, portable navigation systems as well as in-vehicle navigation systems have been released, and a portable navigation system can be constructed with a similar configuration.
In that case, the mobile terminal can be configured with either a mobile phone or a PHS.
(Personal Digital Assistant
A similar system can be constructed for a terminal integrated with t). Further, in the PHS system, base stations are installed in units of several hundred meters, and in order to further simplify the system, a GPS receiver may not be used and location information from the base station may be used.

[0050]

According to the group position display device of the present invention, in order to solve the above-mentioned problem, other user marks are also displayed on the screen of the navigation system so that the positions of other members can be visually grasped. Also, if the line is always connected during the service, the fee will increase, but this service only sends and receives fixed-length packets at regular intervals, and if the call control is performed automatically, the user side Is simplified, and billing is reduced.

As shown in this proposal, it is conceivable to perform all processing on the navigation system without using a server on the network side, but the processing becomes complicated because data transmission / reception with a plurality of users occurs. Moreover, the unit price of each terminal becomes expensive. Therefore, in the system proposed in the present invention, common data transmission and reception,
By leaving the control of the data editing part to a server connected to the network, the processing is simplified, and the navigation system requires only a slight modification to the existing functions.
