Joint optimization of a radio access network and a distributed antenna system

A joint radio access network-distributed antenna system-self-optimizing network (RAN-DAS-SON) entity, comprising:

• a first interface configured to receive a first set of parameters from one or more nodes of a radio access network;
• a second interface configured to receive a second set of parameters from a unit of a distributed antenna system;
• a third interface configured to communicate with an element management system/network management system (EMS/NMS) entity associated with the radio access network;
• wherein the joint RAN-DAS-SON entity is configured to:
• provide the first set of parameters and the second set of parameters to the EMS/NMS entity;
• obtain target parameters for the one or more nodes of the first radio access network and target parameters for the one or more nodes of the distributed antenna system;
• and
• provide instructions to adjust one or more configuration settings of at least one node of the distributed antenna or at least one node of the radio access network based on the target parameters for the one or more nodes of the first radio access network or the target parameters one or more nodes of the distributed antenna system.

A radio access network-distributed antenna system-self-optimizing network (RAN-DAS-SON) entity comprising:

• a first interface configured to communicate with one or more nodes of a radio access network;
• a second interface configured to communicate with a unit of a distributed antenna system comprising a head-end unit communicatively coupled to one or more remote antenna units, wherein the head-end unit of the distributed antenna system is communicatively coupled to the one or more nodes of the radio access network;
• wherein the joint RAN-DAS-SON entity is configured to:
• receive traffic load information for a plurality of carrier signals from the radio access network and/or the distributed antenna system;
• determine target parameters for the radio access network and the distributed antenna system based on the traffic load information for the plurality of carrier signals;
• and
• provide instructions to adjust one or more configuration settings for the one or more remote antenna units of the distributed antenna based on the target parameters.
