Abstract

Outage detection and recovery in heterogeneous networks may benefit from sub-cell level, multi-layer degradation detection, diagnosis, and recovery. For example, cell outage detection and cell outage compensation may benefit from appropriate use of sub-cell level and multi-layer diagnosis and recovery techniques applied to degradation and outage scenarios. A method can include self-healing at least one first cell in a network or at least one second cell in the network. The network includes the at least one first cell and the at least one second cell. The at least one first cell and the at least one second cell have at least partially overlapping coverage. The self-healing can include a network device, such as a network management device, applying at least one of multi-layer reasoning to integrate information of different cell layers or sub-cell level reasoning to consider fine-granular location information. The self-healing can be based on location information.
