Communication system and communication method for a frame synchronization

A communication system comprising:

• a Precision Time Protocol (PTP) grandmaster configured to provide a PTP clock reference via a PTP network;
• and
• a server connected to the PTP grandmaster via the PTP network, the server being configured to generate a frame event and a frame number for a frame synchronization based on a synchronization to the PTP clock reference using PTP,
• the server having an application that is programmed to generate the frame number based on a time of the PTP clock reference,
• the application further programmed to derive the time of the PTP clock reference based on a time of a system clock of the server and a difference between the time of the system clock of the server and the time of the PTP clock reference.

• and
• a server connected to the PTP grandmaster via the PTP network, the server being configured to generate a frame event and a frame number for a frame synchronization based on a synchronization to the PTP clock reference using PTP,
• the server having an application that is programmed to generate the frame number based on a time of the PTP clock reference,
• the application further programmed to generate the frame number by dividing the time of the PTP clock reference by a frame time length.

A communication method performed by a system including a server, the communication method comprising:

• obtaining, by the server, a PTP clock reference from a Precision Time Protocol (PTP) grandmaster via a PTP network, the server being connected to the PTP grandmaster via the PTP network;
• and
• generating, by the server, a frame event and a frame number for a frame synchronization based on a synchronization to the PTP clock reference using PTP,
• the generating of the frame event further including generating, by an application of the server, the frame event at a predetermined interval synchronized to the PTP clock reference,
• the predetermined interval counted by an application timer of the application that is synchronized to a frame event timing defined by a time of the PTP clock reference.
