1Productivity
If advanced load sharing mechanisms are implemented, then load sharing efficiency is improved, but computational capacity requirements increase beyond what is available in radio access control circuitries
Solution Approach 1:
The patent segments the load sharing mechanism into two parts: a simplified component that can be implemented in radio access control circuitries with limited computational capacity, and an advanced component that operates with sufficient computational resources. This segmentation allows the system to achieve improved load sharing efficiency while respecting the computational limitations of the radio access control circuitries.
2Productivity
If advanced load sharing mechanisms are implemented, then load sharing efficiency is improved, but implementation difficulty increases due to challenges in combining with coordinated resource management
Solution Approach 1:
The patent divides the load sharing mechanism into simplified and advanced components, where the simplified component can be easily implemented and coordinated with resource management, while the advanced component provides enhanced functionality. This segmentation reduces implementation difficulty by allowing the core system to operate with the simpler mechanism while optionally enabling advanced features.

AI summary
There is provided load sharing performed by a first processing unit device and a second processing unit device. The load sharing is achieved by the first processing unit device determining a distinct subset of user equipment, UE, from a set of UEs, where the UEs of the distinct subset of UEs are candidates for load sharing. Information identifying the UEs in the distinct subset and information of load of a first cell in which the distinct subset of UEs are served and information of load of a second cell being a candidate cell for serving the distinct subset of UEs is transmitted to the second processing unit device. Based on evaluating the information received from the first processing unit device the second processing unit device determines a load sharing action for use by the first processing unit device.
