Self-organizing network mechanism for energy saving during an outage
Described herein is a self-organizing network (SON) configured to receive information indicating that access network equipment is experiencing a power outage. In response, the SON determines at least one of a time since the power outage, a present configuration of the access network equipment, a characteristic of the access network equipment, or a value of a performance indicator associated with the access network equipment. The SON then generates an updated configuration of the access network equipment based at least in part on the at least one of the time since the power outage, the present configuration of the access network equipment, the characteristic of the access network equipment, or the value of the performance indicator. Further, the SON then provides the updated configuration to the access network equipment.
