MTC Terminal Paging Response Delay Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR networks, MTC terminals initiating paging responses simultaneously cause network congestion due to immediate responses upon receiving paging indications, leading to performance degradation.
Innovation Solution
MTC terminals determine a time-delay value for delaying their paging responses, allowing them to perform the response at a target time point, which reduces the likelihood of simultaneous responses and alleviates network congestion by sending a terminal capability parameter to support delayed responses during network registration.

Engineering Contradiction Analysis
1Speed
If MTC terminals immediately initiate paging response upon receiving paging indication, then the paging response speed is improved, but network congestion occurs due to simultaneous responses from multiple terminals
Solution Approach 1:
The patent implements periodic action by introducing a time-delay mechanism where MTC terminals do not respond immediately to paging indications but instead wait for a predetermined time period before initiating their paging response. This temporal spacing transforms the simultaneous responses into staggered responses, effectively reducing network congestion while maintaining acceptable response speeds.
Solution Approach 2:
The patent applies preliminary action by having MTC terminals pre-configure and store time-delay values in advance before receiving paging indications. When a paging indication is received, the terminal retrieves the pre-configured time-delay value and applies it immediately, enabling fast response without real-time calculation delays while still achieving congestion reduction through the predetermined delay period.
2Adaptability or versatility
If MTC terminals send terminal capability parameter during network registration, then the network side can allow delayed paging response, but the network registration process complexity increases
Solution Approach 1:
The patent applies universality by integrating the terminal capability parameter transmission into the existing network registration process flow. The same registration messaging infrastructure is used to convey both standard registration information and the additional delayed paging response capability indicator, thereby avoiding the creation of separate signaling procedures and minimizing additional complexity.
Solution Approach 2:
The patent implements self-service by enabling MTC terminals to autonomously indicate their delayed paging response capability through the terminal capability parameter during registration. The network side simply needs to receive and store this information without requiring complex processing or additional interaction with the terminal, allowing the terminal to self-configure its preferred response behavior.

AI summary
A paging processing method applied to a Machine-Type Communication (MTC) terminal includes: determining a time-delay value of delaying a paging response according to a paging indication sent by a network side, the paging indication being indicative of presence of a paging to the MTC terminal; determining a target time point for performing the paging response according to the time-delay value; and performing the paging response at the target time point.
