Network Node Connection Evaluation via Secondary Cell Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating connections between network nodes and User Equipment (UE) in wireless communications networks are inefficient, leading to unnecessary resource wastage and delays, particularly when assessing the suitability of additional connections via secondary cells, as they often rely on signaling and inter-frequency measurements that can be costly in terms of resources and time.
Innovation Solution
A method involving the initiation of a first message from a first network node to the UE via a second cell, with feedback from the UE providing time value differences and connection quality metrics, allowing for proactive evaluation of connection usage without prior knowledge of channel conditions, thereby avoiding resource wastage and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inter-frequency measurements and signaling are used to evaluate connection suitability, then connection quality assessment is achieved, but resource consumption and evaluation time increase
Solution Approach 1:
The patent applies preliminary action by establishing a radio connection through the second cell before performing inter-frequency measurements. The network node sets up the connection in advance, so that when evaluation is needed, the measurement infrastructure is already in place and ready to use, eliminating the time delay of establishing connections during actual measurement operations
Solution Approach 2:
The patent uses an intermediary approach by introducing a pre-established radio connection as a mediator between the network node and the measurement process. This intermediary connection serves as a dedicated channel for measurements, allowing quality assessment without requiring new connection setups during the actual evaluation, thus reducing time loss while maintaining measurement precision
2Measurement precision
If inter-frequency measurements are performed to assess connection suitability, then accurate evaluation is achieved, but resource wastage increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing radio connections through candidate second cells before measurement evaluation is required. This allows the measurement infrastructure to be ready in advance, eliminating the need to set up expensive measurement resources temporarily during actual evaluation, thus reducing resource wastage while maintaining accurate assessment capability
Solution Approach 2:
The pre-established connections serve themselves as dedicated measurement channels. Once established, these connections automatically provide the necessary infrastructure for inter-frequency measurements without requiring additional resource allocation, making the measurement process self-sufficient and reducing overall resource consumption while maintaining evaluation accuracy
3Measurement precision
If connections are evaluated after establishment, then connection quality can be assessed, but latency increases
Solution Approach 1:
The patent applies preliminary action by establishing radio connections through the second cell before actual data transmission begins. This pre-establishment means that when data needs to be transmitted, the connection path is already validated and ready, eliminating the latency that would otherwise occur from establishing connections during urgent data transmission scenarios
4Productivity
If additional connections via secondary cells are set up, then resource aggregation is improved, but resource wastage occurs if connections are not suitable
Solution Approach 1:
The patent applies preliminary action by pre-establishing radio connections through candidate second cells and performing inter-frequency measurements before actual data transmission. This allows the network node to identify suitable secondary cells in advance and aggregate resources only from connections that have been validated as appropriate, preventing resource wastage from establishing connections to unsuitable cells while maintaining the productivity benefits of resource aggregation

AI summary
A method for evaluating a connection between a first network node and a User Equipment (UE) via a second cell. The first network node serves a first cell. A sending of a first message is initiated. The first message is sent from the first network node to the UE via the second cell. The first message comprises a trigger for the UE to respond by sending a second message comprising feedback relating to the connection to the second cell. A time value difference between the sending of said first message and receiving of said second message in the first network node is obtained. The second message comprises the feedback relating to the connection sent from the UE in response to the first message. Then it is evaluated how the connection shall be used based on the obtained time value difference and the received feedback.
