Dual Connection Handover for Security and Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, handovers between base stations with different security capabilities often result in insufficient radio resource throughput, leading to suboptimal user experiences due to the inability of target base stations to support higher security capabilities.
Innovation Solution
A method where a terminal is handed over from a source base station not supporting a certain security capability to a target base station that does, by obtaining and establishing dual connections with both base stations, allowing the terminal to access more radio resources and higher data transmission rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal is handed over from a source base station to a target base station with higher security capability, then the security capability is improved, but the radio resource throughput cannot meet user requirements due to the target base station's limited capabilities
Solution Approach 1:
The patent merges the capabilities of multiple base stations by establishing dual connections between the terminal and both the target base station (with higher security capability) and the source base station (with higher throughput capability). This combination allows the terminal to simultaneously utilize security enhancements and high-speed data transmission, resolving the contradiction between improved security and maintained throughput.
2Productivity
If the terminal establishes dual connections with multiple base stations, then the radio resource throughput is improved, but the device complexity increases
Solution Approach 1:
The target base station acts as an intermediary that coordinates the dual connection setup. It obtains the first security capability from the core-network network element and manages the interaction between the terminal and the source base station, thereby simplifying the overall system complexity while enabling throughput improvement through dual connections.
3Reliability
If the target base station obtains and uses the first security capability, then the security capability is improved, but the base station capability requirements increase
Solution Approach 1:
The system dynamically adapts to different base station capabilities by allowing the terminal to establish dual connections. The terminal can flexibly utilize the target base station for security-critical communications while maintaining connections to the source base station for high-throughput data transmission, enabling dynamic capability matching without requiring all base stations to have identical high capabilities.

AI summary
Embodiments of the present invention provide a communication method. The communication method includes: performing, by a terminal, a handover from a source base station to a target base station via an interface between the source base station and the target base station, obtaining, by the target base station, a first security capability, and sending, by the target base station, the first security capability to another base station, to establish dual connections. The source base station does not support the first security capability, and the target base station, the another base station, and a core-network network element support the first security capability. The target base station obtains the first security capability, so that the terminal can establish the dual connections to the target base station and the another base station. In this way, the terminal can obtain more radio resources and a higher data transmission rate, thereby increasing a radio resource throughput and improve user experience.
