Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broadband core network is deployed to support data-intensive devices, then service capability and user experience are improved, but network cost and resource consumption increase significantly
Solution Approach 1:
The patent segments the core network into multiple independent core networks (broadband core network and M2M core network) that can operate separately. Each core network is optimized for specific device types and service requirements, allowing M2M devices to use the lightweight M2M core network while broadband devices use the full-featured broadband core network, thus reducing overall network resource consumption while maintaining service capability.
Solution Approach 2:
The patent implements dynamic network selection and switching mechanisms that allow user equipment to dynamically choose or switch between different core networks based on real-time service requirements, device capabilities, and network conditions. This dynamic adaptation enables the network to optimize resource allocation continuously, ensuring broadband services get full capability while M2M services consume minimal resources.
2Device complexity
If a single core network structure is used for all devices, then network simplicity is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The patent divides the unified core network into multiple specialized core networks (broadband core network and M2M core network) with different functional configurations. This segmentation allows each core network to be optimized for its specific purpose, improving resource utilization efficiency while maintaining manageable complexity through modular design and standardized interfaces.
Solution Approach 2:
The patent creates a multi-functional network architecture where user equipment can access multiple core networks through a unified interface. The system provides universal access capabilities while supporting specialized services, allowing the same user equipment to seamlessly switch between broadband and M2M core networks based on service needs, thus improving resource utilization without requiring multiple separate device configurations.
3Reliability
If broadband core network resources are allocated to M2M devices, then service availability is ensured, but resource allocation efficiency decreases
Solution Approach 1:
The patent applies local quality by providing different levels and types of network resources to different device types based on their specific requirements. M2M devices receive optimized resources from the M2M core network tailored for low-power, intermittent communication, while broadband devices receive full resources from the broadband core network. This localized resource optimization ensures service availability for each device type while maximizing overall resource allocation efficiency.
Solution Approach 2:
The patent implements self-service mechanisms where user equipment automatically selects or switches between core networks based on its own service requirements and capabilities. The system includes automated service matching, capability matching, and switching control that enables devices to self-determine the appropriate core network without manual intervention, ensuring service availability while optimizing resource allocation through intelligent, device-driven decisions.

AI summary
Techniques described herein may enable a wireless telecommunications network to implement different types of core networks, and enable end devices—user equipment (UEs) such as broadband devices (e.g., smartphones, tablets) and Internet of Things (IoT)/Machine Type Communication (MTC) devices (sometimes referred to herein as Machine-to-Machine (M2M) devices)—to connect to whichever core network is most suitable to the capabilities of the UE. For example, a broadband core network may provide UEs with broadband connectivity for media sessions (e.g., telephone calls, video calls, etc.) and broadband Internet access. An M2M core network may provide UEs with network connectivity consistent with the lower resource usage patterns typical M2M devices. Additionally, a UE connected to a first core network (e.g., an M2M core network) may detect a prompt to connect to a second core network (e.g., a broadband core network), and in response, may dynamically switch to the second core network.
