Multiple Core Network Architecture for Device Traffic Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio access networks fail to differentiate between user devices and M2M devices when managing connections and traffic, leading to inadequate support for higher priority user device connections due to increasing demand for lower priority M2M device support.
Innovation Solution
Implementing a multiple core network architecture where base stations use network identifiers to separately manage user device and M2M device connections and traffic, utilizing distinct management information for each type of device to prioritize and control connections and traffic accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single core network is used to support both user devices and M2M devices, then network simplicity is maintained, but Quality of Service for user devices deteriorates due to increasing M2M traffic demand
Solution Approach 1:
The patent divides the single core network into multiple separate core networks (first core network for user devices, second core network for M2M devices). This segmentation allows independent management and prioritization of different device types, ensuring that M2M traffic growth does not degrade user device QoS while maintaining operational simplicity through standardized interfaces.
2Adaptability or versatility
If M2M device support is increased to meet growing demand, then device compatibility improves, but connection prioritization deteriorates as user device connections receive insufficient priority
Solution Approach 1:
By creating separate core networks for user devices and M2M devices, the patent enables independent optimization of each network. The first core network can be optimized for user device priorities and QoS requirements, while the second core network handles M2M device scalability, eliminating the need to choose between supporting more devices and maintaining connection prioritization.
Solution Approach 2:
The patent applies different management information and policies to different core networks based on their specific requirements. User device core network receives management information optimized for human user priorities and interactions, while M2M core network receives management information optimized for machine-to-machine communication patterns, allowing each to operate with locally appropriate quality characteristics.
3Measurement precision
If separate management information is used for different device types, then connection control precision improves, but network complexity increases
Solution Approach 1:
The patent segments the network into multiple core networks, each with its own management information optimized for specific device types. This segmentation provides the precision needed for differentiated connection control while managing complexity through modular architecture where each core network can be independently configured and maintained.
Solution Approach 2:
The patent implements universal interfaces and protocols that allow multiple core networks to operate with different management information while maintaining compatibility with the broader network infrastructure. This universality enables precise control within each network segment while presenting a unified interface to external systems, thereby reducing overall complexity.

AI summary
A base station may receive an indication to manage a connection, associated with a device, or traffic associated with the device. The indication may include a network identifier associated with a core network. The base station may determine, based on the network identifier, management information associated with managing the connection or the traffic associated with the device. The base station may manage, based on the management information, the connection or the traffic associated with the device.
