Title: CONFIGURATION MANAGEMENT IN A COMMUNICATION NETWORK
Abstract:
A method of operating a control entity of a communication network comprises storing (101) configuration data for a node (10) of the communication network. The control entity determines (102) a congestion level of the communication network. The control entity sets (103) a duration of a heartbeat signal waiting period based on the determined congestion. The duration of the heartbeat signal waiting period increases with increased congestion. The control entity determines (104) if synchronisation of configuration data is required with the node based on whether a heartbeat signal, or a predetermined number of heartbeat signals, is received from the node within the heartbeat signal waiting period. The control entity may determine (102) a congestion level of the communication network based on delay times of configuration notifications received from a node (10), or a plurality of nodes (10), in the network.
