Access Network Device Paging for UE Release Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, there is a challenge in accurately determining whether User Equipment (UE) should be released from an inactive state, as existing methods involve UE initiating a connection recovery request for purposes other than release, leading to ambiguity for network devices regarding the intention behind the request.
Innovation Solution
A method where a network-side device transmits a paging message specifically to release UE from an inactive state, and the UE responds with a message that confirms the intention, allowing the network device to definitively determine and proceed with releasing the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device uses existing paging message and connection recovery request mechanism, then the UE can be released, but the network device cannot accurately determine whether the UE should be released or not due to ambiguous intentions
Solution Approach 1:
The patent segments the release determination process into distinct phases: first determining whether to release UE based on paging message and response, then separately determining whether to actually execute the release. This segmentation allows the network device to clearly differentiate between UE that should be released and those that should remain in inactive state, resolving the ambiguity in release intention.
Solution Approach 2:
The patent introduces a preliminary determination step before actual release execution. The network device first determines whether to release UE by examining the response message content, and only after this preliminary assessment does it proceed to execute the release. This preliminary action ensures accurate determination before any resource allocation changes occur.
2Productivity
If the network device releases UE without accurate determination, then resource allocation can be optimized, but unnecessary resource allocation may occur leading to wasted resources
Solution Approach 1:
The patent employs feedback mechanisms where the UE responds to paging messages with response messages that contain information about the UE's actual needs. The network device uses this feedback to accurately determine whether release is appropriate, preventing unnecessary resource allocation and ensuring that resources are only allocated when truly needed, thus avoiding wasted energy.
Solution Approach 2:
The patent performs preliminary determination of release suitability before executing any resource allocation changes. By first assessing the response message and determining whether release is appropriate, the network device avoids premature or incorrect resource allocation, ensuring that resources are only allocated efficiently when the UE truly needs to be released.
3Ease of operation
If the network device waits for UE to initiate connection recovery request, then the release process can be triggered, but the determination accuracy is reduced due to multiple possible intentions
Solution Approach 1:
Instead of waiting for the UE to initiate connection recovery requests and hoping to infer release intention, the patent inverts the approach by having the network device actively send paging messages and interpret the response messages to determine release suitability. This inversion provides clearer determination accuracy by directly addressing the release question rather than inferring it from ambiguous UE-initiated requests.
Solution Approach 2:
The patent uses feedback from response messages to clarify the UE's state and intentions. By analyzing the content of response messages returned by UEs, the network device can accurately determine whether the UE should be released, transforming the ambiguous UE-initiated requests into clear, actionable information about release suitability.
Data Source
AI summary
The application provides a data processing method and a related device. The method includes that: a first access network device transmits a paging message; the first access network device receives a first response message fed back by User Equipment (UE) to the paging message; and the first access network device determines to release the UE. With adoption of the embodiments of the application, a network-side device may determine whether to release the UE or not.
