METHOD, APPARATUS AND NETWORK NODE FOR IDENTIFYING CONNECTIONS AFFECTED BY A NODE FAILURE IN AN ACCESS NETWORK

摘要

Plural communication connections are established between an external network and subscriber units by way of an access network. The subscriber unit connection is supported by plural nodes. When a failure is detected in a node, those subscriber unit connections affected by that failure are identified. A message identifying those subscriber unit connections affected by the failure is sent to one or more other nodes. Affected subscriber unit connections identified in the message are released. Those unaffected connections not included in the message are maintained.
