Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks transitioning to IPv6, mobile terminals often need to support both IPv4 and IPv6 dual stacks, but synchronous communication mechanisms can cause single-PDP dual-stack modes to revert to dual-PDP dual-stack modes, leading to unnecessary dialing and resource waste due to network compatibility issues.
Innovation Solution
A single-PDP dual-stack serial dialing method and system that simplifies the dialing process by setting serial dialing parameters, initiating PDP activation requests, and providing feedback response information to determine the dialing mode based on activation results and reference information, allowing for efficient mode switching and resource optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If synchronous communication mechanism is used for dialing instructions, then communication efficiency is improved, but single-PDP dual-stack mode reverts to dual-PDP dual-stack mode causing unnecessary dialing processing and resource waste
Solution Approach 1:
The patent introduces a feedback mechanism where the mobile terminal reports the actual PDP activation result (single-PDP or dual-PDP mode) back to the host driver. This feedback loop allows the host to adjust subsequent dialing instructions based on the actual network response, preventing redundant dialing operations and resource waste while maintaining communication efficiency.
Solution Approach 2:
The patent makes the dialing mode dynamic by allowing the system to switch between single-PDP and dual-PDP modes based on real-time network conditions and activation results. The synchronous communication mechanism is adapted to handle mode transitions dynamically, preventing the system from being locked into a single mode and enabling efficient resource utilization across diverse network environments.
2Adaptability or versatility
If serial transmission of dialing instructions is used, then communication compatibility is improved, but single-PDP dual-stack mode automatically returns to dual-PDP dual-stack mode
Solution Approach 1:
The patent applies preliminary action by having the mobile terminal pre-configure and report its PDP activation status before the host driver sends subsequent dialing instructions. This preliminary feedback allows the host to prepare appropriate dialing commands in advance, reducing the complexity of mode switching and maintaining serial transmission compatibility across different network environments.
Solution Approach 2:
The patent segments the dialing process into distinct phases: PDP activation phase, feedback reporting phase, and dialing instruction phase. This segmentation allows the serial communication mechanism to handle each phase separately, maintaining compatibility while simplifying the overall control logic for managing single-PDP and dual-PDP modes.
3Adaptability or versatility
If blind dialing is performed to support multiple network environments, then adaptability is improved, but unnecessary dialing processing and dialing failure waste system resources
Solution Approach 1:
The patent uses feedback from the mobile terminal's PDP activation results to guide subsequent dialing operations. The host driver receives information about whether the network supports single-PDP or dual-PDP modes and adjusts its behavior accordingly, eliminating blind dialing attempts in incompatible networks and improving overall processing efficiency while maintaining adaptability.
Solution Approach 2:
The patent performs preliminary PDP activation and network capability detection before initiating dialing operations. By pre-determining whether the network supports single-PDP or dual-PDP modes, the system can prepare appropriate dialing instructions in advance, avoiding unnecessary dialing processing and resource waste in incompatible network environments.

AI summary
A method and system for single-PDP dual-stack serial dialing is provided. A mobile terminal sets a single-PDP dual-stack serial dialing parameter according to a parameter setting command transmitted by a host; then the mobile terminal initiates a PDP activation request to a mobile communication network according to a first dialing instruction transmitted by the host and the configured single-PDP dual-stack serial dialing parameter, acquires activation response information fed back by the mobile communication network, generates dialing response information according to the activation response information, and feeds back the dialing response information to the host, wherein the dialing response information includes cause reference information. And after receiving the dialing response information, the host can acquire a specific condition of the current mobile network according to the cause reference information included in the dialing response information to determine a dialing mode.
