Communication system and communication apparatus
First Claim
1. A communication system comprising:
- a first communication transceiver wirelessly communicating with a second communication transceiver;
a first controller coupled to the first communication transceiver, the first controller configured totransmit a first signal from the first communication transceiver to the second communication transceiver and to receive a second signal from the second communication transceiver, the first signal at least including information enabling to specify the first communication transceiver, anddetermine whether the first communication transceiver is out of order according to a reception status of the second signal; and
a second controller coupled to the second communication transceiver, the second controller configured to transmit the second signal from the second communication transceiver to the first communication transceiver upon receiving the first signal sent from the first controller via the first communication transceiver,wherein;
the first controller further determines a congestion degree of communication in the first communication transceiver; and
the first controller transmits the first signal from the first communication transceiver to the second communication transceiver when the congestion degree of communication in the first communication transceiver is equal to or less than a predetermined threshold.

Abstract
A communication system including a first communication apparatus and a second communication apparatus is provided. The first communication apparatus includes a communication portion. The second communication apparatus includes a communication portion. The first communication apparatus includes a first transmission portion. The first transmission portion transmits a first signal to another communication apparatus. The first signal at least includes information enabling to specify the first communication apparatus. The second communication apparatus includes a second transmission portion. The second transmission portion transmits a second signal to the first communication apparatus. The first communication apparatus includes a malfunction determination portion. The malfunction determination portion determines whether the communication portion of the first communication apparatus is out of order. The communication system includes a congestion determination portion. At least one of the first signal and the second signal is transmitted.

15. A second communication apparatus comprising:
-
a second communication transceiver wirelessly communicating with a first communication transceiver; and a second controller coupled to the second communication transceiver, the second controller configured to transmit a second signal from the second communication transceiver to the first communication transceiver upon receiving a first signal from the first communication transceiver, and determine a congestion degree of communication in the second communication transceiver, wherein; the second controller transmits the second signal from the second communication transceiver to the first communication transceiver, when the congestion degree of communication in the second communication transceiver is equal to or less than a predetermined threshold; the first signal corresponds to a response request signal that requests a transmission of a response signal to the first communication apparatus; the second signal corresponds to the response signal responding to the response request signal; the second controller determines whether a predetermined time elapses after transmission of the second signal by the second controller; the second controller transmits the second signal from the second communication transceiver to the first communication transceiver when determining that the predetermined time elapses and when the second communication transceiver receives the first signal from the first communication transceiver; and the second communication transceiver transmits the second signal when the congestion degree of communication in the second communication transceiver is equal to or less than the predetermined threshold.
