Mobile Station Packet Routing via Subscriber Identity Card Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for handling packet-switched data transmissions by mobile stations with multiple subscriber identity cards are inefficient, as they lack a systematic approach to manage and route packets effectively between different RF modules and subscriber identity cards, leading to suboptimal performance and resource utilization.
Innovation Solution
A method and system that utilize two RF modules and subscriber identity cards to manage packet-switched data transmissions by collecting information about the packets and hardware status, determining the appropriate subscriber identity card for transmission, and routing packets through the corresponding RF module, allowing for efficient handling of uplink and downlink IP packets by clustering requests and assigning appropriate source addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile station uses multiple subscriber identity cards for packet-switched data transmissions, then service versatility and user convenience are improved, but packet routing management complexity and resource utilization efficiency deteriorate due to lack of systematic routing approaches
Solution Approach 1:
The patent segments the packet routing management by dividing packets into different groups based on their characteristics and requirements. Each group is routed through specific RF modules and subscriber identity cards according to predefined routing rules, transforming the complex multi-card routing problem into manageable segmented routing tasks.
Solution Approach 2:
The patent changes the routing parameters dynamically by collecting information about packet characteristics and hardware status, then determining the optimal subscriber identity card for transmission. This parameter-based routing approach adapts to different transmission scenarios and hardware conditions, resolving the complexity through systematic parameter management.
2Productivity
If packet routing decisions are made based on comprehensive information collection about packets and hardware status, then routing optimization and resource utilization are improved, but information processing time and system complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-establishing routing rules and criteria before actual packet transmission. The system collects and processes routing information in advance, determining optimal paths beforehand, which reduces the time required for real-time routing decisions while maintaining high resource utilization efficiency.
Solution Approach 2:
The system implements self-service mechanisms where the mobile station autonomously collects its own hardware status information and makes routing decisions based on predefined rules without requiring external intervention. This self-service approach minimizes processing overhead and reduces information processing time while maintaining efficient resource utilization.
3Productivity
If packets are clustered and grouped for transmission through specific RF modules, then transmission efficiency and resource allocation are improved, but device complexity and routing logic increase
Solution Approach 1:
The patent applies segmentation by dividing packets into distinct groups or clusters based on their transmission requirements. Each cluster is assigned to specific RF modules and subscriber identity cards, creating a structured routing logic that improves transmission efficiency while keeping the grouping rules systematic and manageable.
Solution Approach 2:
The patent creates a universal routing framework that can handle different packet types and transmission scenarios through a unified clustering and grouping mechanism. This multi-functional routing logic applies the same fundamental principles across various transmission cases, improving efficiency without proportionally increasing complexity.

AI summary
A method for handling packet-switched data transmissions by a mobile station with a first subscriber identity card coupled to a first radio frequency (RF) module and a second subscriber identity card coupled to a second RF module, executed by an adapter of the mobile station, is provided. An uplink Internet protocol (IP) packet is received. Information regarding at least one of the received packet and hardware status of the mobile station is collected. One subscriber identity card is determined from the first and second subscriber identity cards according to the collected information. The received packet is transmitted to an IP network via the RF module corresponding to the determined subscriber identity card.
