US 11,895,543 B2 · MRO for 5G networks

Abstract

A method and system to provide Mobility Robustness Optimization (MRO) in a NR network are described. The MRO parameters, use case, management services and information definition and procedures are described. A distributed self-organized network (D-SON) management function requests a producer of provisioning management service (MnS) to set targets, handover parameter ranges, and control information for an MRO function and then enables the MRO function for a non-enabled NR cell. The MRO function receives and analyses information from UEs to determine actions to optimize MRO performance. The D-SON management function collects and analyses MRO related performance measurements to evaluate the MRO performance, and updates the targets, handover parameter ranges, and/or control information when the MRO performance does not meet the targets.

Dependent claims

An apparatus configured to operate as a distributed self-organizing network (D-SON) management function in a new radio (NR) network, the apparatus comprising:

processing circuitry configured to:
send, to a producer of provisioning Management Service (MnS), at least one request to configure at least one target, control parameters, and at least one range of handover parameters for a Mobility Robustness Optimization (MRO) function, the control parameters including MRO function control to enable and disable MRO functionality, a maximum deviation of handover trigger, and a minimum time between handover trigger changes;
send, after transmission of the at least one request, a request to the producer of provisioning MnS to enable an unenabled MRO function for an NR cell;
collect MRO-related performance measurements from the MRO function for the NR cell;
analyze the MRO-related performance measurements to evaluate MRO performance and determine whether the at least one target has been met after optimization of the MRO performance;
and
in response a determination that the at least one target has not been met, send, to the producer of provisioning MnS, at least one update request to update at least one of the at least one range of handover parameters or the control parameters;
and
memory configured to store the MRO-related performance measurements.
