Multi-Card User Equipment Shared Wireless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-card user equipment can only provide services for one subscriber identity card at a time, leading to high hardware costs and complex wireless transmission requirements.
Innovation Solution
Implementing a method where data transmission channels for multiple subscriber identity cards share a common wireless connection, reducing hardware complexity and conserving wireless transmission resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate wireless connections are established for each subscriber identity card to enable simultaneous services, then service capability is improved, but hardware cost and complexity increase
Solution Approach 1:
Multiple data transmission channels corresponding to different subscriber identity cards share a common wireless connection. The wireless communication module establishes one wireless connection that is reused by multiple data transmission channels, allowing simultaneous services for multiple cards without requiring separate wireless connections for each card.
Solution Approach 2:
The common wireless connection serves multiple functions by being shared across different data transmission channels. A single wireless connection resource is made universal to handle service requests from multiple subscriber identity cards, eliminating the need for dedicated wireless connections for each card.
2Adaptability or versatility
If separate wireless connections are established for each subscriber identity card, then service capability is improved, but wireless transmission resources are consumed
Solution Approach 1:
Multiple data transmission channels corresponding to different subscriber identity cards share a common wireless connection. The wireless communication module establishes one wireless connection that is reused by multiple data transmission channels, allowing simultaneous services for multiple cards without requiring separate wireless connections for each card.
Solution Approach 2:
Instead of allocating full separate wireless connections for each subscriber identity card, the system uses a shared wireless connection that is partially allocated to different cards as needed. This partial allocation allows multiple cards to access wireless resources simultaneously without requiring the full resource allocation that separate connections would demand.

AI summary
A multi-card user equipment and a method for processing its service are provided. The method includes, when receiving service request corresponding to a first subscriber identity card, implementing data transmission channel between user equipments and a network which is corresponding to the first subscriber identity card to process the service request; the data transmission channel corresponding to at least two of the subscriber identity cards shares a common wireless connection. With the method, providing services for multiple cards at the same time can be available, meanwhile hardware cost and complexity is decreased, and wireless transmission resources is saved.
