Method and apparatus for detecting event in communication network

A network node, comprising:

• a processor;
• and
• a memory, the memory containing instructions which, when executed by the processor, cause the network node to:
• obtain at least one parameter associated to an event;
• determine, by a first classifier, whether a first measurement result of the at least one parameter satisfies at least one rule;
• classify, by a second classifier, a second measurement result of the at least one parameter, when the first measurement result of the at least one parameter satisfies the at least one rule;
• and
• determine whether the event happens based on a classifying result of the second measurement result of the at least one parameter.

A non-transitory computer-readable storage medium storing instructions which, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• obtaining at least one parameter associated to an event;
• determining, by a first classifier, whether a first measurement result of the at least one parameter satisfies at least one rule;
• classifying, by a second classifier, a second measurement result of the at least one parameter, when the first measurement result of the at least one parameter satisfies the at least one rule;
• and
• determining whether the event happens based on a classifying result of the second measurement result of the at least one parameter.
