1. A communication system, comprising:
a server; and
a communication control apparatus to be connected to the server through a wide area network and to at least one device of a home energy management system through a local area network, the communication control apparatus being configured to transmit a device message generated by the at least one device to the server through the wide area network, wherein
the communication control apparatus includes a processor configured to
acquire the device message from the at least one device,
determine whether the device message satisfies a non-transmission condition, the non-transmission condition being satisfied by a non-transmission device message not to be transmitted to the server and being defined as corresponding to a set of IP address information and at least one of source class information or destination class information included in the non-transmission device message, wherein the source class information indicates a class of the at least one device that is a source of the device message and the destination class information indicates the class of the server,
responsive to determining that the non-transmission condition is not the non-transmission device message, transmit the device message to the server, and
responsive to determining that the non-transmission condition is the non-transmission device message, discard the device message.
