Auxiliary Call Links for Weak-Signal Voice Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network signal weaknesses or failures in call processes lead to issues such as voice discontinuity, no sound, and call dropping due to poor network distribution, mutual interference, and building blocking, resulting in lost or delayed call data packets.
Innovation Solution
Establishing an auxiliary link in conjunction with a primary link to transmit call data packets, utilizing point-to-point or server auxiliary links based on IP or D2D protocols, or core network links via base stations or Wi-Fi devices, to enhance call quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single primary link is used for call transmission, then the system complexity is low, but the call reliability deteriorates due to network signal weakness or failure
Solution Approach 1:
The patent combines a primary link and an auxiliary link into a unified call transmission system. The terminal device simultaneously maintains both links and can switch between them or use them in combination, thereby improving call reliability without requiring completely separate systems.
Solution Approach 2:
The auxiliary link is established in advance before the primary link fails. The terminal device proactively sets up the auxiliary link as a backup, so when network signal weakness or failure occurs on the primary link, the switch to auxiliary link can happen immediately without delay, improving call reliability.
2Reliability
If an auxiliary link is established to improve call quality, then the call reliability improves, but the device complexity increases
Solution Approach 1:
The terminal device autonomously manages the auxiliary link without requiring complex control from the network side. The terminal itself performs link establishment, monitoring, and switching operations, reducing the complexity burden on the overall system while maintaining high call reliability.
Solution Approach 2:
The patent introduces an auxiliary link as an intermediary transmission path between the terminal and the network. This intermediary link acts as a buffer or alternative route when the primary link fails, improving reliability while keeping the core system architecture relatively simple.
3Reliability
If multiple links are used for call transmission, then the call quality improves, but the resource overhead increases
Solution Approach 1:
The terminal device establishes and maintains an auxiliary link partially, only when needed for call transmission. The auxiliary link can be activated selectively based on call quality requirements, and the terminal can switch between using only the primary link, only the auxiliary link, or both in combination, optimizing resource usage while maintaining call quality.

AI summary
This application relates to the field of communications technologies, and in particular, to an auxiliary-link-based call compensation system and apparatus, and chip. The system includes: a first terminal, a second terminal, and a core network device. The first terminal and the second terminal establish a primary link in response to a dialing operation entered by a user. The first terminal and the second terminal establish at least one auxiliary link in response to an auxiliary link establishment condition. The first terminal transmits call data packets with the second terminal by using the primary link and the at least one auxiliary link. The first terminal and/or the second terminal performs post-processing and playing on the call data packets received by using the primary link and the at least one auxiliary link.
