Patent ID: 11943108
Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. A system for operating a telecom network having a Service Level Agreement, SLA, the system comprising:
a policy engine module comprising control circuitry configured to:
obtain 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;
determine a desired state of the telecom network based on the desired value of the at least one state variable;
select 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
send the selected set of policy actions to an action orchestrating module for execution of the selected set of policy actions; and
wherein the system further comprises an SLA monitoring module comprising control circuitry configured to:
obtain 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;
obtain a plurality of state variable thresholds, wherein each state variable of the plurality of state variables is associated with at least one state variable threshold;
form alarm data upon a crossing of a threshold of at least one state variable based on a comparison between the obtained plurality of state variables and the obtained plurality of state variable thresholds;
form the annotated alarm data by associating the formed alarm data with the desired value of at least one state variable of the telecom network; and
send the annotated alarm data to the policy engine module.
