Solution Overview
Problem
Current wireless communication systems face challenges in effectively combining measurement results from RAN nodes in a wireless communication system, particularly for split bearers, which affects performance statistics such as QoS statistics.
Innovation Solution

Engineering Contradiction Analysis
1Measurement precision
If measurement results from multiple RAN nodes are combined for split bearers, then measurement performance and QoS statistics accuracy are improved, but the complexity of measurement processing and result integration increases
Solution Approach 1:
The patent segments the measurement processing by introducing measurement windows that divide the measurement period into discrete segments. Each RAN node performs measurements within specific measurement windows, and results are combined window-by-window rather than continuously. This segmentation reduces the complexity of integrating measurements from multiple nodes by providing clear temporal boundaries and structured result aggregation points.
Solution Approach 2:
The patent applies preliminary action by having RAN nodes perform measurements and store results within predefined measurement windows before combination. The measurement configuration, including window parameters, is established in advance, allowing nodes to independently accumulate measurement data during designated periods. This preliminary measurement accumulation within structured windows simplifies the subsequent combination process at the anchor node.
2Reliability
If measurement windows are configured for combining results from multiple RAN nodes, then QoS statistics derivation is improved, but the configuration and coordination overhead between nodes increases
Solution Approach 1:
The measurement window configuration serves multiple functions simultaneously: it defines the measurement period, establishes the result combination boundary, and provides synchronization reference for multiple RAN nodes. The same measurement window parameters are used across different nodes for the same measurement type, creating a universal timing structure that simplifies coordination while enabling accurate QoS statistics derivation from combined results.
