DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail based on preferred examples shown in the drawings. In the embodiments described below, a mobile terminal represented by a mobile phone (hereinafter also simply referred to as “terminal”) will be described as an example of a mobile terminal.
[0014]
FIG. 1 is a configuration diagram of a network system including a network device according to a first embodiment of the present invention, where A is a user A terminal, B is a user B terminal, and C is a network device.
In FIG. 1, reference numeral 1 denotes a user position recognition processing unit (hereinafter referred to as “user position recognition unit”) that recognizes and holds the position of the user in real time through the terminal held by the user. 2) recognizes the direction and speed in which the user is moving in real time and holds the user speed recognition unit 3 recognizes the ID of the user B (destination) designated by the user A Each of the destination recognition units to be held is shown.
[0015]
Further, 4 is a traffic information database storing real-time operating conditions of public transportation, 5 is the current position of the user A held in the user position recognizing unit 1, and the user speed recognizing unit 2 The transportation means determination unit that searches the traffic information database 4 based on the direction and speed of the user A and identifies the transportation facility that the user A is using is shown.
[0016]
6 is the traffic information database based on the current positions of the users A and B held by the user position recognition unit 1 and the public transportation used by the user A provided by the transportation means determination unit 5. 4 shows a required time / route calculation unit that grasps the time and route required for the user A to move to the position where the user B is by searching 4. Reference numeral 7 denotes a transmission unit that transmits the calculated required time and route to the user A.
[0017]
Details of the functions of these processing units will be described below.
[0018]
The user position recognition unit 1 is a processing unit that realizes a function of recognizing and holding the current position of each user in real time via a user terminal. For example, the above-described GPS function may be provided in the terminal, and the terminal may regularly contact the user position recognition unit 1 with the current position. In addition, the terminal here does not need to be user-specific permanently, and should just have a function which distinguishes a user at arbitrary time. For example, the user may be temporarily specified by typing a user-specific ID into the terminal.
[0019]
The user speed recognition unit 2 is a processing unit that realizes a function of recognizing and holding the speed and direction in which each user moves in real time. This may be calculated based on position information at each successive time, and this calculation can be performed on either the terminal side or the network device side.
[0020]
The destination recognition unit 3 is a processing unit that realizes a function of recognizing and holding the ID of the user B instructed by the user A. Here, the ID is not limited as long as the terminal that the user is currently using can be distinguished. For example, the ID may be unique to the terminal, such as a mobile phone number. It is also possible to specify the terminal that the user currently has by inputting the ID into the terminal.
[0021]
The transportation database 4 holds operation status data of public transportation, and the public transportation that the user is using can be specified by searching using the current position, moving speed, and moving direction of the user as keys. it can. In addition, by searching using public transportation, the current position, and the destination as keys, it is possible to calculate the required time and route to the destination.
[0022]
When public transportation is not used, the required time and route to the destination can be calculated by searching using the current position and the destination as keys. For the calculation of the required time and route, for example, a method used in a navigation service of public transportation service provided on the Internet or the like may be used.
[0023]
It is also conceivable to specify a route search option in advance. For example, the shortest route priority, the cheapest route priority, the least congested route priority, etc. can be considered. In addition, in the case of Shinkansen or limited express use, the route that has been designated as a seat can be preferentially searched by registering the route in consideration of the availability of seats or the fact that the user has designated a seat in advance on the terminal, etc. Is also possible. As the data to be used, it is desirable not to be a simple timetable but to reflect in real time the disorder of transportation due to various troubles.
[0024]
The transportation means determination unit 5 searches the transportation system database 4 based on the current position of the user A obtained by the user position recognition unit 1 and the moving speed and direction of the user A obtained by the user speed recognition unit 2. Thus, it is a processing unit that realizes a function of specifying and maintaining the transportation facility currently used by the user A.
[0025]
The required time / route calculating unit 6 is based on the current positions of the user A and the user B obtained by the user position recognizing unit 1 and the information on the transportation facility used by the user A obtained by the transportation means determining unit 5. Thus, it is a processing unit that realizes a function of grasping the time / route required for the user A to move to the current position of the user B by searching the traffic information database 4.
In addition, even when the user's B ID is not specified as the destination but the building or address is specified, it is necessary for the user A to move to the destination by using the traffic information database 4 described above. It is clear that the time and route can be grasped.
[0026]
The transmission unit 7 is a processing unit that realizes a function of transmitting to the user A the time / route required for the user A to move to the current position of the user B, obtained by the required time / route calculation unit 6.
This transmission destination may be not user A but user B or another third party in some cases. Moreover, about the display method of the content to transmit, a map can also be used together with the display by words. When using the map display, a function for accessing the map database is required, but adding such a map access function does not depart from the spirit of the present invention.
[0027]
In the above embodiment, the calculation result at the time when the user A requested to calculate the required time and route through his / her terminal is notified. However, in some cases, the calculation of the time when a predetermined condition different from this is satisfied. It is more useful to notify the result. For example, a function of notifying a predetermined user when a required time to a predetermined destination becomes smaller than a predetermined value, or a plurality of users are registered in advance as the user B, and the user A For example, a function of notifying the user B that the time required to move to the current position of B is smaller than a predetermined value can be considered.
[0028]
These functions can be realized by adding a function of periodically transmitting the time required for the user A to move to the destination or the current position of the user B and satisfying a predetermined condition. It is obvious that adding such a function does not depart from the spirit of the present invention.
[0029]
Moreover, in the said Example, although required time and a route are calculated based on the request | requirement from the user A using public transportation, the user A using public transportation by the request from the user B is calculated. It is also possible to calculate the time and route required to move to the current position of user B.
[0030]
For example, the time and route required for the user A to move to the current location of the user B is calculated in the user A terminal by sending the location information of the user B and the ID of the user B as the destination to the user A terminal. The user B's terminal may be notified of the calculation result, or the user A's location information and the information on the transportation system used by the user A can be obtained from the network device C. It is also possible to calculate the time and route required for A to move to the current position of user B at the terminal of user B.
