COMMUNICATION APPARATUS, CONTROL METHOD FOR COMMUNICATION APPARATUS, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18340712 titled 'COMMUNICATION APPARATUS, CONTROL METHOD FOR COMMUNICATION APPARATUS, AND STORAGE MEDIUM

Simplified Explanation

The patent application describes a communication apparatus that performs time synchronization using precision time protocol (PTP). It calculates the residence time of a time synchronization packet in a repeater communication apparatus.

  • The communication apparatus obtains the sending time and reception time of a time synchronization packet.
  • It calculates the residence time of the packet in the repeater communication apparatus.
  • The apparatus can function as a repeater that sends packets without applying certain processing.

Potential applications of this technology:

  • Network communication systems requiring precise time synchronization.
  • Industrial automation systems that rely on synchronized communication.
  • Telecommunication networks that need accurate timekeeping for various applications.

Problems solved by this technology:

  • Ensures accurate time synchronization between communication apparatus.
  • Facilitates efficient packet transmission in repeater communication apparatus.
  • Reduces the complexity of time synchronization processing.

Benefits of this technology:

  • Improved accuracy in time synchronization for critical applications.
  • Simplified implementation of repeater communication apparatus.
  • Enhanced efficiency and reliability in network communication systems.


Original Abstract Submitted

A communication apparatus connected to a first another communication apparatus is configured to: obtain a sending time of a time synchronization packet for performing time synchronization processing in accordance with precision time protocol (PTP), sent from a second another communication apparatus connected to the first another communication apparatus, in the second another communication apparatus; obtain a reception time of the time synchronization packet in the communication apparatus; and calculate a residence time of the time synchronization packet in the first another communication apparatus using the sending time and the reception time in a case where the first another communication apparatus functions as an apparatus operating as a repeater that sends a packet received from the communication apparatus or the second another communication apparatus without applying certain processing to the packet.
