Abstract

The present disclosure presents a method and an apparatus for distributed updating of a self organizing network. For example, the disclosure presents a method for transmitting, via a transmitting component at a base station, a portion of data collected at the base station to a network entity, wherein the data collected at the base station is received by the base station from one or more user equipments (UE) in communication with one or more base stations, wherein the base station is one of the one or more base stations, receiving feedback, from the network entity, associated with one or more network parameters of the base station, wherein the feedback received from the network entity is determined at the network entity at least based on the portion of data transmitted from the one or more base stations to the network entity, and updating the one or more network parameters at the base station based on the feedback received from the network entity and local information at the base station. As such, distributed updating of a self organizing network may be achieved.

4. The method of claim 3, wherein the minimum values for the one or more network parameters are determined by the network entity in response to detecting coverage gaps in the self organizing network based at least on the portion of data transmitted from the one or more base stations.

5. The method of claim 3, further comprising setting a transmit power of the base station to a value based on the minimum value and data collected at the base station from the one or more UEs.

6. The method of claim 5, wherein the data collected at the base station comprises one or more of a number of UEs camped on the base station, a location of the UEs camped on the base station, a signal to interference plus noise ratios (SINR) of the one or more UEs camped on the base station, and a path loss of the one or more UEs to the base station.

7. The method of claim 1, wherein updating the one or more network parameters based on the local information at the base station includes updating the one or more network parameters based on information at the base station related to one or more of pilot pollution, call failures, and handover failures.
