GTPU Peer Reporting for Selective User Deactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication protocols, the information of a local GTPU peer is not carried when the user plane reports a message of failed communication with a neighboring GTPU peer to the control plane, leading to the deactivation of all associated users, which negatively impacts user experience.
Innovation Solution
A method and apparatus for reporting local GTPU peer information by detecting communication status between local and neighboring GTPU peers and sending this information to the control plane, allowing it to selectively deactivate only affected users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the user plane reports only neighboring GTPU peer information when communication fails, then the reporting process is simple, but the control plane deactivates all associated users including those that can still communicate, deteriorating user experience
Solution Approach 1:
The patent segments the GTPU peer information into two distinct parts: neighboring GTPU peer information and local GTPU peer information. By reporting both segments together, the system enables the control plane to identify which specific local GTPU peer has communication failures while preserving information about other functional local peers, thus avoiding unnecessary user deactivations.
Solution Approach 2:
The patent introduces an intermediary reporting mechanism that carries both neighboring and local GTPU peer information together in a single report message. This intermediary structure allows the control plane to accurately map communication failures to specific local peers without requiring complex additional queries or assumptions.
2Reliability
If the control plane deactivates all users associated with a neighboring GTPU peer upon receiving a failure report, then the system ensures network reliability by removing potentially problematic connections, but it unnecessarily disrupts users associated with functional local GTPU peers, reducing user experience
Solution Approach 1:
The control plane uses the segmented information (neighboring GTPU peer + local GTPU peer pairing) to precisely identify which user-plane connections are affected by failures. This segmentation enables selective deactivation of only those users associated with failed local peers, while preserving connections for users associated with functional local peers.
Solution Approach 2:
The patent applies local quality by treating each local GTPU peer's communication status independently. Instead of applying a uniform deactivation rule to all users associated with a neighboring peer, the system evaluates and handles each local peer's status individually, preserving service quality for unaffected users.
3Reliability
If detailed local GTPU peer information is included in failure reports, then the control plane can accurately identify and deactivate only affected users, improving user experience, but the reporting message becomes more complex and larger
Solution Approach 1:
The reporting message is segmented into structured fields: neighboring GTPU peer information and local GTPU peer information. This segmentation organizes the detailed data in a systematic manner that is easier to process than unstructured detailed information, reducing the effective complexity despite the increased detail.

AI summary
Disclosed are a local GTPU node information reporting method, an apparatus, and a computer readable storage medium. Said method comprises: local GTPU nodes of a user plane gateway each detecting whether it is connected to neighboring GTPU nodes, to obtain detection results, the detection results comprising information concerning the local GTPU nodes having made a determination of disconnection with the neighboring GTPU nodes; and sending the detection results to a control plane gateway, so that the control plane gateway finds a corresponding user according to the information concerning the local GTPU nodes in the detection results, so as to restrict the user from using the local GTPU nodes.
