Solution Overview
Problem
Conventional radio access networks face challenges in efficiently distributing the load of mobile devices across scheduling units due to fluctuating connections and disconnections, which are difficult to manage without significant bandwidth, processing, and memory requirements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequent reporting of connection data is implemented to track fluctuating connections and disconnections, then load distribution accuracy is improved, but bandwidth consumption increases
Solution Approach 1:
The patent implements periodic sampling of connection data at predetermined time windows instead of continuous monitoring. The system collects connection information at regular intervals and determines peak connections based on these periodic samples, reducing the frequency of data transmission while maintaining adequate load distribution accuracy.
Solution Approach 2:
The patent extracts only the essential peak connection information from the full connection data set. Instead of transmitting all connection and disconnection events, the system identifies and reports only the maximum number of connected UEs during each sampling period, filtering out redundant data to reduce bandwidth consumption.
2Speed
If real-time connection data reporting is implemented, then load distribution responsiveness is improved, but processing resources are consumed
Solution Approach 1:
The system performs load distribution updates at periodic intervals rather than in real-time for every connection event. By sampling connection data at predetermined time windows and updating load distribution based on these periodic measurements, the system maintains responsiveness while significantly reducing processing requirements.
Solution Approach 2:
The system performs preliminary determination of peak connections within each time window before reporting to the network manager. This preliminary processing aggregates multiple connection events into a single peak value, reducing the computational burden on network management systems while maintaining adequate responsiveness.
3Measurement precision
If continuous monitoring of connection fluctuations is implemented, then network management accuracy is improved, but memory requirements increase
Solution Approach 1:
The patent extracts only the essential peak connection value from the continuous stream of connection data. Instead of storing all connection and disconnection events, the system identifies and retains only the maximum number of connected UEs during each monitoring period, dramatically reducing memory requirements while maintaining network management accuracy.
Solution Approach 2:
The system implements periodic sampling of connection data at predetermined time windows, storing measurements only at these discrete intervals rather than continuously. This periodic approach reduces the volume of data that must be retained in memory while still providing adequate network management accuracy through regular updates.

AI summary
Computer-implemented methods, apparatuses, and non-transitory storage media for determining peak connections in a distributed environment are provided. In some implementations, determining peak connections in a distributed environment can include receiving, according to a predetermined time schedule, data indicating a number of user equipments (UEs) connected to and a number of UEs disconnected from each of a plurality of scheduling units of a radio access network (RAN) during each of a plurality of time windows in a first period of time, determining, based on the received data, a maximum number of UEs connected to the scheduling units at a time in the first period of time, and transmitting the determined maximum number of UEs to a network manager of the RAN.
