Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods in LTE systems face issues with discontinuous service reception and impaired data quality due to switching between Point-To-Point (PTP) and Point To Multipoint (PTM) modes, leading to inefficiencies in resource utilization and user experience.
Innovation Solution
A method and apparatus for configuring a target transmission mode for multicast services, allowing terminals to continuously receive service data by receiving configuration information and adjusting transmission modes accordingly, ensuring seamless data reception and quality by utilizing assistance information, indication information, and unicast bearers to synchronize sequence numbers and maintain data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network side dynamically switches between PTP and PTM modes to maximize system resource efficiency, then resource utilization is improved, but service reception continuity and data quality are impaired
Solution Approach 1:
The network side performs preliminary actions by determining the target transmission mode before the terminal receives service data. Configuration information indicating the target mode (PTP or PTM) is sent to the terminal in advance, allowing the terminal to prepare for continuous reception without interruption during mode transitions.
Solution Approach 2:
The system implements feedback mechanisms where the network side monitors terminal reception status and dynamically adjusts transmission mode configurations. This feedback loop ensures that mode switching occurs only when it maintains service continuity, resolving the contradiction between resource efficiency optimization and reception reliability.
2Productivity
If the network side dynamically switches between PTP and PTM modes to maximize system resource efficiency, then resource utilization is improved, but data quality is impaired
Solution Approach 1:
The network side determines the target transmission mode and sends configuration information to the terminal before data transmission begins or resumes. This preliminary configuration ensures that the terminal is properly prepared to receive data in the target mode, preventing quality degradation during mode transitions.
Solution Approach 2:
The invention maintains continuous data reception by ensuring that mode switching does not interrupt the useful action of data transmission. The terminal continuously receives service data without gaps or quality loss, even as the network dynamically switches between PTP and PTM modes for resource optimization.
3Reliability
If configuration information is sent to instruct terminals to continuously receive service data, then service reception continuity is improved, but transmission mode flexibility is reduced
Solution Approach 1:
The system dynamically adjusts transmission modes based on real-time conditions while maintaining continuous service reception. The network side can flexibly switch between PTP and PTM modes by sending updated configuration information to terminals, ensuring both continuity and adaptability are achieved through dynamic reconfiguration rather than fixed mode assignment.
