Dual-Connectivity Control Using SIB-Based NR Capability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Certain networks fail to support NR networks, leading to unnecessary information transmission and network overload when user terminals attempt to connect, necessitating frequent software updates to adapt.
Innovation Solution
An electronic device dynamically controls EN-DC operations based on network state without requiring software updates, enabling seamless communication across different network environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user terminal transmits information according to the NR specification, then the user terminal can communicate with the NR network, but a network which does not support the NR network receives unnecessary information causing network overload
Solution Approach 1:
The user terminal dynamically adjusts its communication behavior based on real-time network capability detection. The terminal determines whether to transmit NR information based on whether the network supports NR, changing its operation mode from static to adaptive, thereby avoiding unnecessary information transmission to non-NR networks while maintaining compatibility with NR networks
Solution Approach 2:
The user terminal receives network information (such as system information blocks) that indicates whether the network supports NR. Based on this feedback, the terminal adjusts its information transmission behavior accordingly, enabling the network to control the terminal's communication mode and prevent overload on networks that do not support NR
2Object-generated harmful factors
If the user terminal updates software to prevent network overload, then the network overload problem is reduced, but the user terminal requires frequent software updates
Solution Approach 1:
The user terminal autonomously detects network NR support capability and automatically adjusts its own communication behavior without requiring external software updates. The terminal uses its own resources to determine network compatibility and makes decisions about information transmission independently, eliminating the need for frequent software updates from the terminal side
Solution Approach 2:
The network provides feedback information (network capability indicators) to the user terminal, enabling the terminal to adapt its behavior based on the network's capabilities. This feedback mechanism shifts the complexity from the terminal software to the network side, where the network can control information transmission based on its own capabilities

AI summary
The electronic device includes wireless communication circuitry, at least one processor operatively connected with the wireless communication circuitry, and a memory operatively connected with the at least one processor. The memory stores instructions which, when executed, cause the at least one processor to control the electronic device to: identify a state of the electronic device, receive a system information block (SIB) from a first base station supporting a first cellular network via the wireless communication circuitry, identify whether a network to which the electronic device belongs supports dual connectivity (DC) between the first cellular network and a second cellular network based on information included in the SIB, enable a second cellular network function of the wireless communication circuitry based on the network supporting the DC, and transmit information indicating that the second cellular network function of the electronic device is enabled to the network via the wireless communication circuitry.
