Description

  The present invention relates to a broadcast communication system using a mobile communication terminal such as a mobile phone terminal, a PHS, or a PDA with a communication function.

  Conventionally, a technique in which a user notifies location information at the time of transmission is known from, for example, Japanese Patent Application Laid-Open No. 2003-259426. The technology disclosed in this publication is a position detection unit that acquires information indicating the position of a base station through a base station that communicates with the mobile terminal via a network, and a position of the mobile terminal that includes information indicating the position of the base station. The portable terminal includes position information generating means for generating information and information transmitting means for automatically transmitting the position information to a predetermined destination.

  However, when considering waiting for a plurality of people, each user needs to be a sender, and communication is required many times.

In recent years, GPS functions have been added to small portable terminals, and services such as route guidance using terminal user location information have begun to be provided, and the need for services using terminal user location information is also increasing. .
However, there are currently few useful services that make use of location information.
JP 2003-259426 A

  An object of the present invention is to provide a broadcast communication system that can be used for waiting and the like by monitoring user location information using subscriber information that can be normally known by the network side.

  The broadcast communication system of the present invention includes a database in which members, time and place are set in advance on the network side, and monitoring means for monitoring the presence of a mobile communication terminal of the setting member in a base station including the set place at the set time. And a broadcast communication means for performing broadcast communication to the mobile communication terminal of the setting member based on the monitoring result.

Based on this, there are various forms as follows.
The monitoring means monitors the presence of the mobile communication terminal in the cell area with the position information.
The monitoring means monitors the presence of the mobile communication terminal using GPS information.
The monitoring means monitors for a set time.

The broadcast communication means performs broadcast communication at a preset time.
The broadcast communication means performs broadcast communication with the mobile communication terminal in the place set in the database.
The broadcast communication means performs broadcast communication with a mobile communication terminal other than the place set in the database.

  The broadcast communication means performs broadcast communication of information of another mobile communication terminal to the mobile communication terminal of the setting member. In this case, the information of the other mobile communication terminal is, for example, position information of the other mobile communication terminal.

  When the monitoring means detects the presence / absence of the setting member's portable communication terminal, the broadcast communication means notifies the portable communication terminal to that effect.

  Note that the information to be broadcast in the present invention is not limited to the location information of the mobile communication terminal, but may be various information such as mail, name, telephone number, and alarm.

The present invention has the following effects.
The first effect is that the presence of a member is detected on the network side and notified to all members, so that each member can notify his / her position information and the like to a plurality of persons without performing a transmission process.
The second effect is that the presence of members is detected on the network side and notified to all members, so that each member can grasp the position information and the like of other members without performing transmission processing.
The third effect is that time can be effectively utilized because the user does not need to be in the setting place and needs to be in the vicinity of the setting place when using for waiting or the like.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a system configuration of Embodiment 1 of the present invention.
The user 10 who is scheduled to meet with a plurality of people sets the member, date and place in advance to the user information control unit 12 on the network side.

  On the network side, the information is stored as the database 11, and the base station 13 (the number of base stations M> 1) having a microcell (number of cells N> 1) having a radius of several hundred meters including the set place when the set date and time is reached. ) Is monitored for setting members.

  The base station 13 notifies the user information control unit 12 when the setting member enters the own micro cell. When all the members enter the cell area of the base station 13, the user information control unit 12 determines that all the members have gathered near the set location, and performs the same operation on the mobile communication terminals 14, 15, 16 of all the members. It is notified through the base station 13 that members have been prepared using information communication.

Next, the operation of the configuration shown in FIG. 1 will be described using the flowchart of FIG.
The user 10 who is scheduled to meet with a plurality of people sets the member, date and place in advance to the user information control unit 12 on the network side (step 20). The user information control unit 12 stores the information in the database 11 and collects members in a range that can be detected on the network side on the set date and time, so that the cell area of the microcell (number of cells N> 1) including the set location Is notified to the setting member (step 21). Since the microcell radius is usually several hundred meters, it is possible to determine whether or not the member is near the set location depending on whether or not the target terminal exists in the microcell.

  The user information control unit 12 starts a monitoring timer T minutes before the setting date and time (step 22), and instructs the base station 13 (the number of base stations M> 1) having a microcell including the setting location to start monitoring. Then, the base station 13 starts monitoring the presence of members in the microcell (step 23). Even at present, the network side monitors the location of each terminal. In the present invention, monitoring is intended to monitor whether a specific terminal is under a specific cell.

  If the monitoring timer started in step 22 expires before all members are detected (step 24), it is broadcast to the set member that all members have not been detected and monitoring has ended. (Step 25).

  Until the monitoring timer expires, the base station 13 continues to monitor the presence of the member (step 26), and reports to the user information control unit 12 when the member can be detected in the cell (step 27). The user information control unit 12 receives the report from the base station 13 and notifies the detected members that it has been detected on the network side (step 28). As a result, the member can recognize whether or not he / she has been detected on the network side.

  The user information control unit 12 determines whether all the members are near the set location, that is, whether all the set members are detected (step 29), and if detected, all the members are near the set location. That all members are notified using broadcast communication (step 30).

  In the first embodiment, the member position detection by the micro cell is shown. However, when the GPS function terminal is targeted, the GPS information is notified from each terminal to the network side, and the network side determines the member position based on the information. It is also possible to judge.

It is a system configuration figure of Example 1 of the present invention. It is a flowchart of the operation.
