Abstract

A management apparatus is configured to determine whether or not distribution of status information representing a wireless communication status in a public wireless system including at least one wireless station that executes wireless communication with a wireless terminal is necessary. The distribution is a distribution to a mobile communication terminal via a mobile communication system that provides a mobile communication service to the mobile communication terminal. The management apparatus is configured to transmit, when it is determined that the distribution is necessary, a request to the mobile communication system to set a dedicated fixed channel in a public communication network used in the mobile communication system. The dedicated fixed channel is fixed exclusively for the public wireless system. The management apparatus is configured to transmit the status information to the mobile communication system to distribute the status information to the mobile communication terminal via the dedicated fixed channel.

First claim

What is claimed is:

1. A management apparatus comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
determine whether or not distribution of status information to a mobile communication terminal via a mobile communication system that provides a mobile communication service to the mobile communication terminal is necessary, the status information representing a wireless communication status in a public wireless system including at least one wireless station that execute wireless communication with a wireless terminal;
transmit, when it is determined that the distribution is necessary, a request to the mobile communication system to set a dedicated fixed channel in a public communication network used in the mobile communication system, the dedicated fixed channel being fixed exclusively for the public wireless system; and
transmit the status information to the mobile communication system to distribute the status information to the mobile communication terminal via the dedicated fixed channel, wherein the at least one processor coupled configured to:
determine that the distribution is necessary when warning information representing that wireless communication is unavailable in one wireless station included in the public wireless system is received; and
transmit, as the status information, information representing a radio wave receivable area regarding a wireless station where communication is currently available in the public wireless system other than the wireless station relating to the warning information.

2. A management apparatus comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
determine whether or not distribution of status information to a mobile communication terminal via a mobile communication system that provides a mobile communication service to the mobile communication terminal is necessary, the status information representing a wireless communication status in a public wireless system including at least one wireless station that execute wireless communication with a wireless terminal;
transmit, when it is determined that the distribution is necessary, a request to the mobile communication system to set a dedicated fixed channel in a public communication network used in the mobile communication system, the dedicated fixed channel being fixed exclusively for the public wireless system; and
transmit the status information to the mobile communication system to distribute the status information to the mobile communication terminal via the dedicated fixed channel, wherein the at least one processor coupled configured to:
determine that the distribution is necessary when warning information representing that communication with one wireless station included in the public wireless system is unavailable is received; and
transmit, as the status information, information representing a radio wave receivable area regarding a wireless station where communication is currently available in the public wireless system other than the wireless station relating to the warning information.

3. A management apparatus comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
determine whether or not distribution of status information to a mobile communication terminal via a mobile communication system that provides a mobile communication service to the mobile communication terminal is necessary, the status information representing a wireless communication status in a public wireless system including at least one wireless station that execute wireless communication with a wireless terminal;
transmit, when it is determined that the distribution is necessary, a request to the mobile communication system to set a dedicated fixed channel in a public communication network used in the mobile communication system, the dedicated fixed channel being fixed exclusively for the public wireless system; and
transmit the status information to the mobile communication system to distribute the status information to the mobile communication terminal via the dedicated fixed channel, wherein the at least one processor coupled configured to:
determine that the distribution is necessary when warning information representing an occurrence of a disaster that disables wireless communication in one wireless station included in the public wireless system is received in the public wireless system; and
transmit, as the status information, information representing a radio wave receivable area regarding a wireless station where communication is currently available in the public wireless system other than the wireless station relating to the warning information.

4. The management apparatus according to claim 1 , wherein the at least one processor coupled configured to transmit the warning information as the request.

5. A management apparatus comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
determine whether or not distribution of status information to a mobile communication terminal via a mobile communication system that provides a mobile communication service to the mobile communication terminal is necessary, the status information representing a wireless communication status in a public wireless system including at least one wireless station that execute wireless communication with a wireless terminal;
transmit, when it is determined that the distribution is necessary, a request to the mobile communication system to set a dedicated fixed channel in a public communication network used in the mobile communication system, the dedicated fixed channel being fixed exclusively for the public wireless system; and

transmit the status information to the mobile communication system to distribute the status information to the mobile communication terminal via the dedicated fixed channel, wherein the at least one processor coupled configured to, when the determination unit determines that the distribution is unnecessary after determining that the distribution is necessary, transmit a cancelation request to cancel a setting of the dedicated fixed channel.

6. The management apparatus according to claim 1 , wherein the at least one processor coupled configured to, when the dedicated fixed channel is set and subsequently restoration of communication relating to a wireless station relating to the setting of the dedicated fixed channel is detected, transmit the detection result as a cancelation request to cancel the setting of the dedicated fixed channel.

7. A communication system comprising:
the management apparatus according to claim 1 , the management apparatus being configured to manage communication in the public wireless system including the at least one wireless station that executes wireless communication with the wireless terminal;
the wireless terminal;
the mobile communication terminal; and
a communication management apparatus configured to manage communication in the mobile communication system that provides the mobile communication service to the mobile communication terminal, wherein
the communication management apparatus includes at least one memory and at least one processor coupled to the at least one memory, the at least one processor being configured to
receive the status information and a request for distribution of the status information from the management apparatus,

set the dedicated fixed channel in the public communication network in response to the request, the dedicated fixed channel being fixed exclusively for the public wireless system, and
transmit the status information to the mobile communication terminal via the dedicated fixed
