Multi-party Call Control for Flexible Terminal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-party call systems lack the ability to flexibly control remote terminals according to different session demands and actions, limiting their functionality in managing uplink and downlink service data.
Innovation Solution
A multi-party call control method and device that allows for the flexible control of remote terminals by setting up calls with multiple terminals, controlling uplink and downlink service data, informing the network to control service data, or instructing terminals to manage their own service data, including options like discarding, cutting off, or prohibiting service data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-party call is realized by setting up multiple calls sequentially, then the call functionality is achieved, but the terminal cannot flexibly control all remote terminals according to different session demands
Solution Approach 1:
The patent introduces a call control function as an intermediary component that mediates between the terminal and multiple remote terminals. This call control function selectively controls uplink and downlink service data of different remote terminals based on session demands, enabling flexible control without requiring complex modifications to the terminal's core architecture. The intermediary layer handles the complexity of multi-terminal control while keeping the terminal's basic call setup mechanism simple.
2Ease of operation
If the terminal controls uplink and downlink service data locally, then control flexibility is improved, but network resource utilization may be reduced
Solution Approach 1:
The patent implements a dynamic control mechanism where the terminal can adaptively switch between local control and network-assisted control modes based on session demands. For example, during audio-only sessions, the terminal may locally discard uplink service data of inactive terminals to save network resources, while during video sessions, it may request the network to control service data. This dynamic adaptation optimizes both control flexibility and network resource utilization.
3Productivity
If service data is discarded at the terminal, then bandwidth consumption is reduced, but service quality may be compromised
Solution Approach 1:
The patent applies different service data handling strategies to different remote terminals based on their specific session requirements. Instead of uniformly discarding or transmitting all service data, the call control function selectively controls uplink and downlink service data for each terminal. For example, audio service data may be discarded for inactive terminals while video service data is preserved for active terminals, ensuring service quality is maintained where needed while optimizing bandwidth efficiency overall.
