SELF-OPTIMIZING NETWORK ENTITY FOR A TELECOMMUNICATIONS SYSTEM
First Claim
1. A method, comprising:
- measuring radio frequency parameters of radio frequency communications between a head-end unit and a remote unit of a distributed antenna system (DAS);
sending measurements of the radio frequency parameters to a self-optimizing network (SON);
determining, by the SON entity, adjustments to operations and management parameters of a radio base station (RBS) using the measurements of the radio frequency parameters; and
sending commands to the RBS for changing the operations and management parameters of the RBS using the adjustments determined by the SON entity.

Abstract
Certain features relate to systems and methods for optimizing the radio frequency characteristics of signals transmitted between a radio base station (RBS) and a distributed antenna system (DAS). A self-optimizing network (SON) entity can determine adjustments to radio frequency operations and management parameters at the RBS based on radio frequency parameters measured by a measurement and configuration module at the DAS. Adjustments to radio frequency operations and management parameters can include adjustments configured to compensate for signal latency caused by the DAS. Adjustments to radio frequency operations and management parameters can also include adjustments to signal gain due to noise rise caused by the DAS. The SON entity can also measure nominal receive power levels for the RBS for purposes of open loop power control.
