Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 2:
3. A method for operating a telecom network having a Service Level Agreement (SLA), the method comprising:
obtaining annotated alarm data comprising an indication of a threshold crossing of at least one state variable of the telecom network defined by the SLA, the annotated alarm data further comprising an indication of a desired value of the at least one state variable of the telecom network;
determining a desired state of the telecom network based on the desired value of at least one state variable;
selecting a set of policy actions from a policy action bank, wherein the policy action bank comprises a plurality of policy actions, each policy action being associated with at least one estimated action effect, and wherein the selection of the set of policy actions is based on the estimated action effects of the plurality of policy actions and on the determined desired state of the telecom network such that the desired state is reachable upon execution of the selected set of policy actions; and
sending the selected set of policy actions to an action orchestrating module for execution of the selected set of policy actions;
wherein each of the plurality of policy actions is further associated with at least one pre-condition of the telecom network, each pre-condition defining a predefined parameter value or a predefined parameter range of a state variable of the telecom network; and
wherein the method further comprises:
obtaining a current state of the telecom network, the current state being defined by current values of a plurality of state variables of the telecom network, and wherein the selection of the set of policy actions is further based on the obtained current state of the telecom network and the pre-conditions; and
wherein the selected set of policy actions comprises a plurality of policy actions, the method further comprising:
obtaining at least one intermediate state of the telecom network, the at least one intermediate state being defined by predicted values of the plurality of state variables of the telecom network during an ordered execution of the selected set of policy actions;
wherein selecting the set of policy actions comprises selecting an order of execution of the selected set of policy actions based on the obtained at least one intermediate state.
