Abstract
A software-defined network (“SDN”) controller can execute a ranking application to determine a radio access network (“RAN”) node group including at least two RAN nodes for which a neighborhood relations ranking is to be computed. The SDN controller can determine at least one metric and a ranking function to be used in computing the neighborhood relations ranking. The SDN controller can fetch current neighborhood data for the at least two RAN nodes in the RAN node group. Based upon the at least one metric and the current neighborhood data, the SDN controller can compute the neighborhood relations ranking. The SDN controller can then provide the neighborhood relations ranking to user equipment operating in the RAN.
Claims20
A method comprising:
- determining, by a software-defined network (“SDN”) controller executing a ranking application, a radio access network (“RAN”) node group comprising at least two RAN nodes for which a neighborhood relations ranking is to be computed;
- determining, by the SDN controller, at least one metric;
- determining, by the SDN controller, a ranking function;
- fetching, by the SDN controller, current neighborhood data for the at least two RAN nodes in the RAN node group;
- computing, by the SDN controller, the neighborhood relations ranking according to the ranking function and based upon the at least one metric and the current neighborhood data;
- and
- providing, by the SDN controller, the neighborhood relations ranking to a user equipment.
A software-defined network (“SDN”) controller comprising:
- a processor;
- and
- a memory comprising instructions that, when executed by the processor, cause the processor to perform operations comprising
- determining a radio access network (“RAN”) node group comprising at least two RAN nodes for which a neighborhood relations ranking is to be computed,
- determining at least one metric,
- determining, a ranking function,
- fetching current neighborhood data for the at least two RAN nodes in the RAN node group,
- computing the neighborhood relations ranking according to the ranking function and based upon the at least one metric and the current neighborhood data, and
- providing the neighborhood relations ranking to a user equipment.
A computer-readable storage medium comprising computer-executable instructions that, when executed by a processor of a software-defined network (“SDN”) controller, cause the processor to perform operations comprising:
- determining a radio access network (“RAN”) node group comprising at least two RAN nodes for which a neighborhood relations ranking is to be computed;
- determining at least one metric;
- determining, a ranking function;
- fetching current neighborhood data for the at least two RAN nodes in the RAN node group;
- computing the neighborhood relations ranking according to the ranking function and based upon the at least one metric and the current neighborhood data;
- and
- providing the neighborhood relations ranking to a user equipment.
