Wireless Device T302 Wait Timer Update Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in handling reject wait times and integrity errors during RRC connection resume procedures, leading to network overload and unnecessary signaling, battery consumption, and interference.
Innovation Solution
Implementing a mechanism to stop, reset, or update the T302 wait timer based on receiving release or suspend messages, and detecting integrity protection verification errors, allowing the wireless device to avoid unnecessary procedures and optimize network behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless device continues to monitor the wait timer expiry after receiving a release or suspend message, then the device ensures it waits for the full wait time period, but this causes unnecessary signaling, battery consumption, and network overload
Solution Approach 1:
The patent applies feedback by having the wireless device monitor whether a release or suspend message is received during the wait time period. If such a message is received, the device uses this feedback information to stop monitoring the wait timer expiry, thereby avoiding unnecessary procedures while still complying with the wait time requirement for critical communications.
Solution Approach 2:
The patent makes the wait timer handling dynamic by allowing the device to adjust its behavior based on received messages. The device transitions from a static wait-only mode to a dynamic mode where it can stop monitoring if a release or suspend message is received, optimizing resource usage while maintaining reliability.
2Loss of energy
If the wireless device stops monitoring the wait timer after receiving a release or suspend message, then battery consumption and signaling are reduced, but the device may not properly wait for the full wait time period
Solution Approach 1:
The patent applies preliminary action by having the device prepare to stop monitoring the wait timer only after confirming receipt of a release or suspend message. This ensures that the device has properly waited for the full wait time period for critical communications before stopping monitoring, thus avoiding premature termination while reducing energy consumption.
Solution Approach 2:
The device uses feedback from the received release or suspend message to make an informed decision about stopping wait timer monitoring. This feedback mechanism ensures that the device only stops monitoring when appropriate, maintaining reliability while reducing battery consumption.
3Reliability
If the wireless device performs full RRC connection resume procedures, then connection reliability is maintained, but network overload and interference increase
Solution Approach 1:
The patent applies partial action by having the wireless device perform only the necessary RRC connection resume procedures. When a release or suspend message is received, the device can stop monitoring the wait timer and avoid performing unnecessary full resume procedures, thereby reducing network interference while maintaining connection reliability when needed.
Solution Approach 2:
The patent converts the potentially harmful effect of network overload into a beneficial outcome by using the release or suspend message as a trigger to stop unnecessary procedures. This transforms what could be seen as a rejection into an opportunity to optimize network resources and reduce interference.

AI summary
Methods and apparatuses are disclosed for updating a wait timer as a result of receiving one of a release message and a suspend message and/or configuring a wireless device (WD) to update a wait timer by determining the one of the release message and the suspend message to be communicated to the WD.
