Method and system for updating clocks in components of a communications network

摘要

Method, system and base station for providing time synchronisation between local clocks located in nodes within a network and a central clock. The proposed invention allows for a more precise time synchronisation to take place in a simple and cost effective manner between a central unit and at least two remote units, without having to modify the transport infrastructure of the system. The central unit upon reception of a global time from a network clock will update, its respective local clock. It will then calculate a regularity of reception of the global time and then schedule the transmission of clock synchronisation messages to the remote units, which in turn on reception of the clock synchronisation messages will update their local clocks.
