1. A communication apparatus that minimizes a retransmission of messages when an error message is received during a communication handshaking procedure, comprising:
- a receiver that receives messages from a central communication apparatus, said receiver detecting an error message during the communication handshaking procedure; and
a retransmission requester that transmits a retransmission request message to the central communication apparatus when said receiver detects the error message.

Abstract
Method and apparatus for minimizing a retransmission of messages when an error message is received during a communication handshaking procedure. A receiver, that detects an error message during the communication handshaking procedure, receives messages from a communication apparatus. When the receiver detects the error message, a retransmission requester transmits a retransmission request message to the communication apparatus.
