Conditional PSCell Addition Optimization via Terminal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for conditional primary secondary cell addition in mobile communications often result in inefficient resource allocation, leading to wasted resources and time-consuming PSCell addition processes due to unreasonable access resource reservation and lack of real-time adaptation to terminal conditions.
Innovation Solution
A method where a terminal sends optimized configuration information to the network, allowing for improved resource allocation and trigger conditions for conditional PSCell addition, enabling faster and more adaptive PSCell addition based on historical and real-time data, thereby optimizing the PSCell addition process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If excessive access resource is reserved for conditional PSCell addition, then the terminal can quickly add PSCell when trigger condition is satisfied, but some access resource is wasted and random access process of another potential terminal may be affected
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the access resource reservation based on terminal capabilities and network conditions. The network device determines reservation parameters (such as time duration and resource quantity) according to terminal type, historical data, and real-time status, thereby optimizing the balance between quick PSCell addition and resource utilization efficiency.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal sends first information (such as terminal type, historical addition data, or real-time status) to the network device. The network device uses this feedback to optimize the access resource reservation parameters, creating a closed-loop system that adapts to actual terminal needs and reduces resource waste.
2Loss of energy
If limited access resource is reserved for conditional PSCell addition, then resource waste is reduced, but the terminal may only add PSCell through traditional time-consuming process
Solution Approach 1:
The patent applies dynamics by making the access resource reservation adaptive rather than fixed. The reservation parameters are dynamically adjusted based on terminal capabilities, historical addition success rates, and current network conditions. This allows the system to allocate sufficient resources when needed for quick addition while reducing reservations when time efficiency is prioritized.
Solution Approach 2:
The patent changes reservation parameters (time duration, resource quantity) based on optimized configuration information received from the terminal. The network device adjusts these parameters to balance between reducing resource waste and maintaining fast PSCell addition capability, creating a flexible reservation mechanism that adapts to different scenarios.
3Device complexity
If traditional PSCell addition process is used, then resource allocation is simple, but the process is time-consuming and less adaptive to terminal conditions
Solution Approach 1:
The patent applies preliminary action by pre-configuring access resources and trigger conditions before the actual PSCell addition is needed. The network device reserves access resources in advance and configures trigger conditions based on terminal capabilities and network state, enabling fast and adaptive PSCell addition when conditions are met without requiring complex real-time resource allocation.
Solution Approach 2:
The patent introduces feedback loops where the terminal provides optimized configuration information (first information) about its capabilities, historical data, or real-time status to the network device. This feedback enables the network to adjust resource allocation strategies, making the system more adaptive and efficient while maintaining manageable complexity through automated optimization.
