Event-based keep alive times in communication networks

摘要

A method of communicating in a network having a plurality of nodes including a base node (BN), and a plurality of service nodes (SNs) having at least one switch node (SW) and at least one terminal node (TN). The method includes at least one of a) a first SN from the plurality of SNs receiving (i) a data/ALV_B/ACK frame from the BN or (ii) a beacon from the BN or SW, and restarting a first KA timer at the first SN upon (i) or (ii), and b) restarting an ALV_S timer at the BN for the first SN upon receiving a data/ALV_S/ACK frame from the first SN.
