Paging Message Processing for Multi-Card Mobile Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-card mobile phones, constantly listening to paging messages from one card to interact with the network reduces the performance of the current card's network data interaction, affecting user experience, as switching states to respond to all messages is resource-intensive and unnecessary.
Innovation Solution
A method where a paging message carries a 'paging cause' that allows user equipment (UE) to determine whether to respond or ignore the message, reducing unnecessary state switches and maintaining performance by only switching to RRC connection state when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal constantly listens to paging messages to maintain network interaction capability, then the network responsiveness is improved, but the performance of current card's network data interaction deteriorates
Solution Approach 1:
The terminal performs partial listening by only monitoring paging messages during specific time windows (ON duration in DRX cycle) rather than continuously listening, and only responds to paging messages that match its identity. This partial action maintains network responsiveness while minimizing interference with current card data transmission.
Solution Approach 2:
The terminal uses discontinuous reception (DRX) with periodic ON and OFF cycles to listen for paging messages. During OFF periods, the terminal focuses resources on current card data interaction, while during ON periods it checks for paging messages. This periodic action resolves the contradiction between maintaining network awareness and preserving data transmission performance.
2Adaptability or versatility
If the terminal switches states to respond to all paging messages, then the service availability is improved, but the resource consumption increases
Solution Approach 1:
The terminal pre-configures its paging monitoring behavior by storing its identity information and paging cycle parameters before entering idle state. This preliminary setup allows the terminal to efficiently filter and identify relevant paging messages without needing to switch states for every paging transmission, reducing resource consumption while maintaining service availability.
Solution Approach 2:
The terminal responds only to paging messages that are relevant to its services and identity, ignoring irrelevant paging messages. This selective partial response maintains necessary service availability while avoiding unnecessary state transitions and resource consumption associated with responding to all paging messages.
3Productivity
If the terminal ignores paging messages to maintain current performance, then the network data interaction performance is improved, but the service responsiveness deteriorates
Solution Approach 1:
The terminal implements feedback mechanisms by monitoring paging messages during DRX ON periods and selectively responding based on message content matching its identity and service requirements. This feedback loop ensures the terminal maintains current performance during OFF periods while still responding appropriately to relevant paging messages during ON periods, balancing productivity and reliability.
