Abstract

A server includes an area information retrieving unit that retrieves, when a phenomenon occurs, information indicating an area of the phenomenon; a subscriber information retrieving unit that retrieves subscriber information of a user terminal served by a base station in the area from a subscriber information management server that associates and manages, for each user terminal, subscriber information and serving base station information, based on the area information; a personal information checking unit that checks the personal information managed by a personal information database against the subscriber information retrieved by the subscriber information retrieving unit, and that identifies the user terminal including the personal information which includes the subscriber information; and a message transmitting unit that reports to the identified user terminal that a user of the user terminal which includes the subscriber information is in the area of the phenomenon.

Claims

1. A radio communication system comprising:

a personal information data server that manages personal information which is stored in a first user terminal;

a subscriber information management server that manages, for each of user terminals, subscriber information and information representing a base station which serves for the user terminal while associating the subscriber information with the information representing the base station; and

a personal information checking server,

wherein the personal information checking server includes

an area information retrieving unit that retrieves, when a specified phenomenon occurs, information representing an area where the specified phenomenon occurs;

a subscriber information retrieving unit that retrieves subscriber information of a second user terminal from the subscriber information management server, based on the information representing the area where the specified phenomenon occurs, wherein the information representing the area where the specified phenomenon occurs is retrieved by the area information retrieving unit, and the second user terminal is served by the base station which is installed in the area where the specified phenomenon occurs;

a personal information checking unit that checks the personal information against the subscriber information, and that identifies the first user terminal that includes the personal information including the subscriber information, wherein the personal information is managed by the personal information data server, and the subscriber information is retrieved by the subscriber information retrieving unit; and

a message transmitting unit that reports to the first user terminal which is identified by the personal information checking unit that there is a user of the second user terminal in the area where the specified phenomenon occurs, wherein the second user terminal includes the subscriber information, and wherein the subscriber information is included in the personal information of the first user terminal.

2. The radio communication system according to claim 1,

wherein the personal information checking server includes a personal information synchronization processing unit that performs synchronization with the personal information data server in regard to the personal information, and

wherein the personal information checking unit checks the personal information against the subscriber information, wherein the personal information is synchronized by the personal information synchronization processing unit, and the subscriber information is retrieved by the subscriber information retrieving unit.

3. The radio communication system according to claim 1,

wherein the personal information checking server includes a personal information retrieving unit that retrieves, when the specified phenomenon occurs, the personal information from the personal information data server, and

wherein the personal information checking unit checks the personal information against the subscriber information, wherein the personal information is retrieved by the personal information retrieving unit, and the subscriber information is retrieved by the subscriber information retrieving unit.

4. The radio communication system according to claim 1,

wherein the personal information managed by the personal information data server includes phonebook data.

5. The radio communication system according to claim 1,

wherein the area information retrieving unit retrieves the information representing the area, wherein the area is specified by at least one of the area which is specified at a cell level, the area which is specified at a tracking area level, and the area which is set by an operator.

6. A server comprising:

an area information retrieving unit that retrieves, when a specified phenomenon occurs, information representing an area where the specified phenomenon occurs;

a subscriber information retrieving unit that retrieves subscriber information of a second user terminal from a subscriber information management server, based on the information representing the area where the specified phenomenon occurs, wherein the subscriber information management server manages, for each of user terminals, the subscriber information and information representing a base station which serves for the user terminal while associating the subscriber information with the information representing the base station, wherein the information representing the area where the specified phenomenon occurs is retrieved by the area information retrieving unit, and wherein the second user terminal is served by the base station which is installed in the area where the specified phenomenon occurs;

a personal information checking unit that checks the personal information against the subscriber information, and that identifies a first user terminal that includes the personal information including the subscriber information, wherein the personal information is managed by a personal information database that manages the personal information stored in the first user terminal, and the subscriber information is retrieved by the subscriber information retrieving unit; and

a message transmitting unit that reports to the first user terminal which is identified by the personal information checking unit that there is a user of the second user terminal in the area where the specified phenomenon occurs, wherein the second user terminal includes the subscriber information, and wherein the subscriber information is included in the personal information of the first user terminal.

7. A message notification method comprising:

an area information retrieving step of retrieving, when a specified phenomenon occurs, information representing an area where the specified phenomenon occurs;

a subscriber information retrieving step of retrieving subscriber information of a second user terminal from a subscriber information management server, based on the information representing the area where the specified phenomenon occurs, wherein the subscriber information management server manages, for each of user terminals, the subscriber information and information representing a base station which serves for the user terminal while associating the subscriber information with the information representing the base station, wherein the information representing the area where the specified phenomenon occurs is retrieved by the area information retrieving step, and wherein the second user terminal is served by the base station which is installed in the area where the specified phenomenon occurs;

a personal information checking step of checking the personal information against the subscriber information, and identifying a first user terminal that includes the personal information including the subscriber information, wherein the personal information is managed by a personal information database that manages the personal information stored in the first user terminal, and the subscriber information is retrieved by the subscriber information retrieving step; and

a message transmitting step of reporting to the first user terminal which is identified by the personal information checking step that there is a user of the second user terminal in the area where the specified phenomenon occurs, wherein the second user terminal includes the subscriber information, and wherein the subscriber information is included in the personal information of the first user terminal.
