Core Network Attach Context Segmentation for Wireless Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks are inefficient in managing connections for low-bandwidth devices, resulting in a low useful-to-useless data ratio due to uncoordinated communication, which hampers the commercial viability of large-scale network deployments.
Innovation Solution
A method and system where a core network attaches User Equipment (UE) to a wireless network, storing and managing attach contexts and operational data sets, allowing UE to transmit packets using a subset of these data sets, and purging unused contexts to optimize resource usage across multiple radio access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core network stores complete attach context for all UEs, then connection reliability is improved, but network resource consumption increases
Solution Approach 1:
The attach context is divided into two subsets: a first subset stored in the core network and a second subset stored in the UE. This segmentation allows the system to maintain necessary connection information while reducing the burden on network resources, as not all context data needs to be retained centrally.
Solution Approach 2:
The patent extracts the second subset of attach context from the core network and stores it locally in the UE. This extraction reduces the amount of data that must be managed and stored in the network, thereby reducing network resource consumption while preserving connection reliability through distributed storage.
Solution Approach 3:
The core network purges the first subset of attach context when it is no longer needed, based on operational data sets that track UE activity and connection status. This allows the network to recover and reuse storage resources while maintaining reliability by keeping context data only as long as necessary.
2Ease of operation
If uncoordinated communication is allowed for simplicity, then ease of operation is improved, but network efficiency deteriorates
Solution Approach 1:
The system implements coordinated communication through feedback mechanisms where the core network monitors UE operational data and adjusts context management accordingly. The network receives packets from UEs, updates operational data sets, and purges context based on this feedback, creating an efficient coordinated system that maintains ease of operation while improving network productivity.
3Reliability
If attach context is retained indefinitely, then connection reliability is improved, but loss of time for resource management worsens
Solution Approach 1:
The patent changes the temporal parameter of context retention by purging the first subset of attach context based on operational data sets that track UE activity over time. This dynamic parameter adjustment maintains reliability for active connections while automatically releasing resources for inactive UEs, reducing the time loss associated with managing stale context data.

AI summary
Apparatuses, methods, and systems for managing a User Equipment (UE) connection to a wireless network are disclosed. One method includes attaching, by a core network, the UE to the wireless network, storing, by the core network, at least a first subset of an attach context and a UE operational data set, wherein the UE stores at least a second subset of the attach context in memory and network operational data sets, wherein the UE transmits packets using the second subset of the attach context and the network operational data sets. The method further comprises receiving, by the core network, the packets from the UE using the first subset of the attach context, and urging by the core network the first subset of the attach context based on the UE network operational data set.
