Self-Healing

Self-healing is a function that mitigates the faults automatically by triggering appropriate recovery
actions.

From the point of view of fault management, for each detected fault appropriate alarms are be generated by the faulty network entity, regardless of whether it is an automatically detected and automatically cleared fault, or an automatically detected and manually cleared fault.

The self-healing functionality monitors the alarms, and gathers necessary correlated information (e.g. measurements, testing result, etc.) and does deep analysis, and triggers appropriate recovery actions to solve the fault.

It also monitors the execution of the recovery actions and decides the next step accordingly. When self-healing iteration ends, the self-healing functionality generates
appropriate notifications to inform the Integration Reference Point (IRP) Manager of all the changes
performed.

This concludes the section on the new radio access network for LTE, and the following chapters cover the new Core Network entities required to support this new technology.
