Abstract:
1. In a wireless communications network having a plurality of nodes including local and neighbor nodes, each of the nodes having a time-of-day (TOD) and one of the nodes including a GPS-based time, a method of synchronizing a TOD of the local node to the GPS-based time, the method comprising the steps of: (a) storing, in the local node, an update value for adjusting a TOD of the local node without losing time synchronization with a TOD of the neighbor node; (b) receiving, in the local node, from the neighbor node, a first integer value corresponding to a number of update values for synchronization of the TOD of the neighbor node to the GPS-based time; and (c) updating, in the local node, the TOD of the local node by the update value stored in step (a), after receiving the first integer value in step (b); wherein the first integer value is based on the following: Integer {t wherein t t Δt is the update value.
