COMMUNICATION SYSTEM AND AUTOMATIC METERING SYSTEM
First Claim
1. A communication system comprising:
- a plurality of ad hoc communication networks formed by one or more communication units and one gateway; and
a monitoring server that monitors the ad hoc communication networks, whereinthe monitoring server determines, on the basis of a monitoring result of load states of the gateways and a monitoring result of a congestion state of radio traffic, whether it is necessary to carry out load distribution control for moving a communication unit subordinate to a predetermined first gateway to be subordinate to a second gateway set around the first gateway and, when determining that it is necessary to carry out the load distribution control, instructs at least one gateway of the first gateway and the second gateway to broadcast-deliver a signal including control information that indicates a condition of a communication unit set as a movement target and instructing reselection of a gateway set as a participation destination.

Abstract
A communication system according to the present invention includes a plurality of ad hoc communication networks each formed by one or more communication units and one gateway and includes a monitoring server that monitors the ad hoc communication networks. The monitoring server determines on the basis of a monitoring result of load states of the gateways and a monitoring result of a congestion state of radio traffic whether it is necessary to carry out load distribution control for moving a communication unit subordinate to a first gateway to be subordinate to a second gateway set around the first gateway and, when determining that it is necessary to carry out the load distribution control, instructs at least one gateway of the first gateway and the second gateway to broadcast-deliver a signal including control information and instructing reselection of a gateway set as a participation destination.

9. A communication monitoring server in a communication system:
- the communication system comprising a plurality of ad hoc communication networks each formed by one or more communication units and one gateway; and
the monitoring server monitoring each of the ad hoc communication networks, whereinthe monitoring server determines, on the basis of a monitoring result of load states of the gateways and a monitoring result of a congestion state of radio traffic, whether it is necessary to carry out load distribution control for moving a communication unit subordinate to a predetermined first gateway to be subordinate to a second gateway set around the first gateway and, when determining that it is necessary to carry out the load distribution control, instructs at least one gateway of the first gateway and the second gateway to broadcast-deliver a signal including control information that indicates a condition of a communication unit set as a movement target and instructing reselection of a gateway set as a participation destination.
- the communication system comprising a plurality of ad hoc communication networks each formed by one or more communication units and one gateway; and
-
10. A gateway in a communication system:
- the communication system comprising a plurality of ad hoc communication networks each formed by one or more communication units and one gateway; and
a monitoring server that monitors each of the ad hoc communication networks, whereinwhen a predetermined condition is satisfied, the gateway broadcast-delivers a signal including control information that indicates a condition of a communication unit caused to be participated to itself and instructing reselection of the gateway set as a participation destination.
- the communication system comprising a plurality of ad hoc communication networks each formed by one or more communication units and one gateway; and
-
11. A communication unit in a communication system:
- the communication system comprising a plurality of ad hoc communication networks each formed by one or more communication units and one gateway; and
the monitoring server monitoring each of the ad hoc communication networks, whereinwhen the communication unit participating in a first gateway receives control information delivered from a second gateway different from the first gateway, and the control information includes a condition of a communication unit caused to be participated to the second gateway, the communication unit determines whether the communication unit switches the participation destination to the second gateway according to a predetermined algorithm.
- the communication system comprising a plurality of ad hoc communication networks each formed by one or more communication units and one gateway; and
