Title:
時間同期支援装置、クロック同期装置、マスタ通信局及びスレーブ通信局
Document Type and Number:
Japanese Patent JP5112095
Kind Code:
B2
Abstract:
A device (DA1) is intended to aid a clock synchronization device (DS1) of a master station (SM) of a wireless network in performing time synchronizations, this master station (SM) comprising a master clock (HM) represented by the value of a master counter (CM) and means (MG1) for generating wireless frames of IP packets containing in particular PTP messages of first and second types. The aid device (DA1) comprises detection means (MD1) for, in case of detection by the physical layer of the master station (SM) of a frame pulse received from the network, triggering the sampling of the value of the master counter (CM)
