SYSTEM AND METHOD OF FAILURE HANDLING IN A RADIO ACCESS NETWORK

摘要

Method and system of failure handling in a radio access network that minimizes the recovery time when a core node fails by storing the routing information of the core node and, whenever said core node fails, loading the routing information in an auxiliary node with the same hardware and software configuration as the core node. The traffic received at the core node is then routed to the auxiliary node through a physical connection that is transparent to the radio access network. The amount of routing information required by this system is minimal, and thus the recovery time is greatly reduced.
