Abstract

A message distribution method according to the present invention includes the steps of: (A) determining, at a message distribution station (CBC), distribution area information and a distribution type, based on a message distribution request received from a flash report transmission station (CBE) and containing distribution target area information, and reporting, from the message distribution station (CBC) to a radio base station (eNB), the distribution area information and the distribution; and (B) determining, at the radio base station (eNB), the distribution area, based on the distribution area information and the distribution type, and distributing, from the radio base station to the mobile station in the distribution area, a predetermined message.

Claims

1. A message distribution method for distributing a predetermined message to a mobile station in a distribution area, comprising the steps of:

(A) determining, at a message distribution station, distribution area information and a distribution type, based on a message distribution request received from a flash report transmission station and containing distribution target area information, and reporting, from the message distribution station to a radio base station, the distribution area information and the distribution; and

(B) determining, at the radio base station, the distribution area, based on the distribution area information and the distribution type, and distributing, from the radio base station to the mobile station in the distribution area, the predetermined message.

2. The message distribution method according to claim 1, wherein the step (A) comprises the steps of:

determining, at the message distribution station, a tracking area, the distribution area information, and the distribution type, based on the message distribution request, and reporting, from the message distribution station to a mobile control apparatus corresponding to the distribution target area, the tracking area, the distribution area information, and the distribution type; and

reporting, from the mobile control apparatus to the radio base station belonging to the tracking area, the distribution area information and the distribution type.

3. The message distribution method according to claim 1, wherein

the radio base station manages a table which stores distribution area information and a distribution area in association with each other for each distribution type;

and

in the step (B), the radio base station refers to the table corresponding to the distribution type, and distributes the predetermined message to a mobile station in a distribution area associated with the distribution area information.

6. The message distribution method according to claim 2, wherein

the radio base station manages a table which stores distribution area information and a distribution area in association with each other for each distribution type;

and

in the step (B), the radio base station refers to the table corresponding to the distribution type, and distributes the predetermined message to a mobile station in a distribution area associated with the distribution area information.

4. A radio base station configured to distribute a predetermined message to a mobile station in a distribution area, wherein the radio base station is configured

to extract distribution area information and a distribution type from the predetermined message reported from a message distribution station;

and

to distribute the predetermined message to a mobile station in a distribution area associated with the extracted distribution area information and distribution type.

5. A message distribution station configured to distribute a predetermined message to a mobile station in a distribution area, wherein the message distribution station is configured

to determine distribution area information and a distribution type, based on a message distribution request received from a flash report transmission station and containing distribution target area information;

and

to transmit a message distribution request containing the distribution area information and the distribution type, to a mobile switching center corresponding to the determined distribution area information.
