Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple modem components are carried to implement compatibility of multiple call protocols, then protocol compatibility is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling a single modem component to handle multiple call protocols through dynamic protocol adaptation. The system allows one modem to serve multiple protocol functions by implementing protocol conversion and switching mechanisms, thereby reducing the need for separate dedicated modems for each protocol while maintaining comprehensive protocol compatibility.
Solution Approach 2:
The patent applies segmentation by separating the protocol handling function from the modem hardware. Instead of requiring dedicated modems for each protocol, the system segments the communication functionality into protocol-specific processing layers that can be dynamically activated. This allows a single modem to be segmented into multiple virtual communication channels supporting different protocols simultaneously.
2Reliability
If modem switching is implemented during call transitions, then call effect is maintained, but switching complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing the second call connection before fully terminating the first call. The system prepares the alternative communication path in advance, validates its readiness, and then smoothly transitions between calls. This preliminary preparation ensures that call effect continuity is maintained while reducing the complexity of real-time switching decisions during active calls.
Solution Approach 2:
The patent introduces an intermediary switching mechanism that manages the transition between different modem components and call protocols. This intermediary layer handles the complexity of protocol conversion, resource allocation, and connection management, thereby simplifying the overall switching control while ensuring reliable call effect continuity during transitions.
3Reliability
If real-time path switching is performed, then call quality is maintained, but processing overhead increases
Solution Approach 1:
The patent implements periodic action by performing path switching at predetermined intervals and trigger events rather than continuously monitoring and adjusting. The system checks call quality parameters at specific intervals and only initiates path switching when predefined conditions are met, thereby maintaining call quality while significantly reducing processing energy consumption compared to continuous real-time adjustment.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting switching thresholds and monitoring intervals based on call conditions. The system modifies its processing parameters adaptively, increasing monitoring frequency only when call quality degrades and reducing it when conditions are stable. This approach maintains high call quality while optimizing energy consumption by avoiding unnecessary processing during stable call states.

AI summary
This application provides a call switching method and apparatus, and an electronic device. The method is applicable to the electronic device. The electronic device includes a first modem configured to process data of a first call and a second modem configured to process data of a second call. The first modem and the second modem support different call protocols. The electronic device obtains a second call request when being in a first call state, and switches the first call to the second call in response to an operation of a user on the second call request. According to the call switching method in this application, the electronic device can carry a plurality of modems supporting different call protocols, and can flexibly switch between call states of different call protocols, to meet call requirements of the user.
