"Radio Communication System, Server, and Message Notification Method" in Patent Application Approval Process

June 24, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- A patent application by the inventors Ishida, Masanori (Chiyoda-ku, JP); Hayashi, Kouki (Chiyoda-ku, JP), filed on July 23, 2012, was made available online on June 12, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Ntt Docomo, Inc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "When a large-scale disaster such as a large earthquake occurs, in addition to a governmental agency and a disaster prevention agency which are engaged in a recovery activity, many users use voice calls to confirm safety in a disaster area. During this time, a large volume of traffic is processed by a network, compared to a normal time. Due to the processing of the large volume of traffic by the network, it becomes a state where it is difficult to establish communication connections. Since it becomes a state in which it is difficult to establish communication connections, the traffic may be controlled by the network by regulating the communications. When the traffic is controlled by the network, it becomes difficult to make confirmation of the safety in the disaster area.

"A technique has been known such that, even if a system of a mobile switching center is down or a transmission line failure occurs, and communication with a radio base station controller is disabled, a terminal of a police station or a fire station can be contacted when a disaster occurs (cf. Patent Document 1, for example).

"Further, a technique has been known such that, in processing of communication requests during a time of disaster, an overcrowded condition or a congestion state is avoided as much as possible, thereby allowing as many users as possible to communicate (cf. Patent Document 2, for example)."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "Problem to be Solved by the Invention

"There are few methods of finding where a relative, a friend, or an acquaintance is (hereinafter, which is referred to as the 'relative or the like') during the time of a large-scale disaster.

"For example, even if the relative or the like stays in a neighborhood of the disaster area due to a business trip or travel, in many cases, this fact is actually found out later after a certain amount of time has passed.

"Further, even if the relative or the like lives in the neighborhood of the disaster area, it is possible that no damage or injury is received because the relative or the like was at another location at the time of the disaster. However, there are no methods of finding whether they are safe, except for confirming by a telephone, for example.

"The present invention is achieved in view of the above-described point. An object of the present invention is to provide a technique by which existence of relatives and the like in a neighborhood of a disaster area can be reported when a disaster occurs.

"Means for Solving the Problem

"In order to solve the above-described problem, the radio communication system is embodied as a radio communication system including

"a personal information data server that manages personal information to be stored in a user terminal;

"a subscriber information management server that manages, for each of the 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; 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, area information representing an area where the specified phenomenon occurs;

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

"a personal information checking unit that checks the personal information managed by the personal information database against the subscriber information retrieved by the subscriber information retrieving unit, and that identifies the user terminal which includes the personal information including the subscriber information;

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

"The personal information checking server may includes a personal information synchronization processing unit that performs synchronization with the personal information data server in regard to the personal information,

"wherein the personal information checking unit may check 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.

"The personal information checking server may include a personal information retrieving unit that retrieves, when the specified phenomenon occurs, the personal information from the personal information data server,

"wherein the personal information checking unit may check 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.

"The personal information managed by the personal information data server may include phonebook data.

"The area information retrieving unit may retrieve 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.

"The server is embodied as the server including

"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 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 the 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 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 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 user terminal, and the subscriber information is retrieved by the subscriber information retrieving unit; and

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

"Further, it can be configured as a message notification method which is executed by the above-described radio communication system.

"Effect of the Present Invention

"According to the disclosed radio communication system, when a disaster occurs, existence of relatives and the like in a neighborhood of the disaster area can be reported.
