Technique for triggering congestion mitigation actions in an O-RAN-compliant communication network

A non-transitory computer-readable medium storing thereon computer-readable program code that, executed by at least one processor, causes at least one processor to perform:

• evaluating a temporal behavior of at least one congestion indicator for individual cells in a cellular radio access network, RAN, domain having an Open RAN, O-RAN, architecture to identify one or more candidate cells that are prone to suffering from congestion;
• correlating, for at least one of the one or more candidate cells, session-related information from a core network domain with RAN information from the RAN domain to derive at least one quality indicator for the at least one candidate cell;
• and
• triggering, dependent on the at least one quality indicator derived for the at least candidate cell, one or more congestion mitigation actions.

An apparatus for triggering one or more congestion mitigation actions in a communication network, the communication network comprising a core network domain and a cellular radio access network, RAN, domain having an Open RAN, O-RAN, architecture, the apparatus being configured to:

• evaluate a temporal behavior of at least one congestion indicator for individual cells in the RAN domain to identify one or more candidate cells that are prone to suffering from congestion;
• correlate, for at least one of the one or more candidate cells, session-related information from the core network domain with RAN information from the RAN domain to derive at least one quality indicator for the at least one candidate cell;
• and
• trigger, dependent on the at least one quality indicator derived for the at least candidate cell, one or more congestion mitigation actions.
