Network Controller Configuring Access Devices for UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies fail to flexibly establish data transmission or reception channels for user equipment (UE) based on its characteristics, leading to inefficient use of radio resources and suboptimal quality of service (QoS).
Innovation Solution
A network controller manages multiple access network devices, including macro and WiFi base stations, to configure appropriate radio resources for UE, enabling efficient data transmission or reception by determining the best access network device based on UE capabilities and service requirements, and facilitating peer-to-peer Wi-Fi communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE selects radio resources based on general access procedures, then network access is achieved, but radio resources are wasted due to inability to flexibly establish channels according to UE characteristics
Solution Approach 1:
The patent applies local quality by configuring different access network devices (macro base station, WiFi base station, small base station) with different functions and characteristics to match specific UE requirements. Each access network device provides specialized service qualities, allowing UE to select the most appropriate device based on its specific service needs and characteristics, thereby avoiding waste of radio resources while maintaining flexibility.
Solution Approach 2:
The patent implements dynamics through the network controller's ability to dynamically configure and allocate different access network devices to UE based on real-time service requirements, UE characteristics, and network conditions. This dynamic configuration allows the system to adapt flexibly to changing conditions and establish appropriate data transmission channels, preventing radio resource waste while maintaining high adaptability.
2Adaptability or versatility
If multiple access network devices supporting different standards are deployed, then radio resources become richer and coverage is extended, but the complexity of selecting and managing appropriate access devices increases
Solution Approach 1:
The patent introduces a network controller as an intermediary between UE and multiple access network devices. The network controller manages the configuration and allocation of different access network devices (macro base station, WiFi base station, small base station), handling the complexity of device selection and coordination. This intermediary simplifies the UE's task to only needing to access the network controller, which then appropriately directs traffic to the most suitable access network device.
Solution Approach 2:
The network controller provides universal functionality by managing multiple types of access network devices with different characteristics and standards. It serves as a single point of contact for all UE access requests, regardless of which specific access network device would be most appropriate, thereby handling the complexity centrally while maintaining the benefits of having diverse access options available.
3Device complexity
If data transmission is routed through core networks, then network management is simplified, but communication delays increase and QoS deteriorates
Solution Approach 1:
The patent segments the network architecture by separating control plane functions (handled by the network controller) from user plane data transmission (handled directly between UE and access network devices). This segmentation allows control signaling to be managed centrally while data transmission occurs through optimized direct paths, reducing delays and improving QoS without sacrificing network management simplicity.
Solution Approach 2:
The network controller performs preliminary configuration and setup actions, establishing appropriate data transmission channels and parameters before actual data transmission begins. This preliminary action includes configuring the UE and access network devices with necessary parameters for direct communication, ensuring that when data transmission occurs, it can proceed efficiently through the most appropriate path without delays.
