RRC Connection Management in Shared Network Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network sharing configurations, inconsistencies in PLMN and cell identifiers can lead to authentication issues during RRC resume and re-establishment procedures, causing difficulties in determining and matching authentication information between communication nodes and user equipment.
Innovation Solution
A method where communication nodes and user equipment determine and verify authentication information using a predetermined subset of input parameters, ensuring consistency and accuracy in authentication processes, particularly during RRC resume and re-establishment procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple PLMN identifiers and cell identifiers are configured in a network sharing cell, then network sharing capability is improved, but authentication consistency between communication nodes and user equipment deteriorates
Solution Approach 1:
The patent applies local quality by making the authentication information determination process specific to each communication node and user equipment pair. Each UE is configured with authentication information based on a predetermined subset of input parameters that is locally consistent between the UE and the communication node, ensuring that authentication works reliably even when multiple PLMN and cell identifiers are present in the network sharing cell.
2Adaptability or versatility
If authentication information is determined using multiple input parameters, then authentication flexibility is improved, but determination accuracy between communication nodes and user equipment deteriorates
Solution Approach 1:
The patent extracts only the necessary subset of input parameters for authentication information determination. Instead of using all available input parameters, the system identifies and uses a predetermined subset that is sufficient for authentication while ensuring consistency between communication nodes and user equipment. This extraction approach maintains authentication flexibility while improving determination accuracy by eliminating unnecessary parameters that could cause inconsistencies.
3Productivity
If RRC resume and re-establishment procedures are performed in network sharing configuration, then connection mobility is improved, but authentication reliability deteriorates due to identifier inconsistencies
Solution Approach 1:
The patent applies preliminary action by pre-configuring authentication information in user equipment based on a predetermined subset of input parameters before the RRC resume or re-establishment procedures are initiated. This preliminary configuration ensures that when the UE needs to resume or re-establish a connection in a network sharing cell, the authentication information is already prepared and consistent, eliminating authentication failures during these mobility procedures.

AI summary
This disclosure relates generally to wireless communications and, more particularly, to systems and methods for radio resource control (RRC) connection management in a network sharing configuration, including an RRC resume from an RRC inactive state, and RRC re-establishment. In one embodiment, a method performed by a communication node, includes: receiving a request from a communication device to establish a current connection associated with a prior connection between the communication device and a prior communication node, wherein the request comprises communication device authentication information; and establishing the current connection based on a determination that communication node authentication information matches the communication device authentication information, wherein the communication node authentication information is based on a predetermined subset of input parameters, and wherein the determination is performed at the communication node or at the prior communication node.
