Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple signal transmission lines are used for handshake mechanism between AP and Modem, then communication connection can be established, but the number of connection lines increases, leading to increased power consumption and hardware resource usage
Solution Approach 1:
The patent combines multiple handshake signals into a single integrated handshake protocol that operates over the existing data transmission lines. Instead of using separate dedicated handshake lines, the invention merges the handshake functionality into the data path, allowing connection establishment without additional physical lines between AP and Modem.
Solution Approach 2:
The existing data transmission lines are made multi-functional by enabling them to carry both data traffic and handshake control signals. This universal usage of the same physical medium for multiple purposes eliminates the need for separate handshake lines, reducing overall connection line count while maintaining reliable communication establishment.
2Reliability
If multiple signal transmission lines are used for handshake mechanism, then communication connection can be established, but power consumption of the system increases
Solution Approach 1:
By merging handshake signals into existing data lines, the invention eliminates the need for additional dedicated handshake lines that would consume extra power. The same physical infrastructure is reused for both data and control functions, reducing overall power consumption while maintaining connection reliability.
3Reliability
If lengthy handshaking process is used to establish connection, then reliable communication can be achieved, but data transmission speed is reduced
Solution Approach 1:
The handshake protocol is designed to execute preliminary connection establishment actions efficiently before actual data transmission begins. By optimizing the sequence and timing of handshake signals, the invention reduces the time required for connection setup, allowing data transmission to start sooner without compromising connection reliability.
4Reliability
If more signal transmission lines are used, then handshake mechanism can be more robust, but hardware resources are wasted
Solution Approach 1:
The invention makes existing data transmission lines multi-functional by enabling them to carry both data and handshake control signals. This universal usage eliminates the need for additional dedicated handshake lines, preventing hardware resource waste while maintaining robust connection establishment through the same physical medium.

AI summary
The present invention discloses a method of mobile terminal internal communications, which belongs to the field of mobile communications. The method comprises: a control signal channel is connected within an application processor module and a baseband processor module, and the control signal channel is composed of a first signal channel, a second signal channel and a feedback channel. A first request signal is sent from the application processor module to the baseband processor module via the first signal channel, and then a feedback is sent from the baseband processor module to the application processor module via the feedback channel. After the feedback is sent to the application processor module, the application processor module starts to send data to the baseband processor module. A second request signal is sent from the baseband processor module to the application processor module, and then the baseband processor module starts to send data to the application processor module.
