Multi-SIM Assistance Information for Paging Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in detecting the paging of one subscriber (e.g., Subscriber2/Network B) when another subscriber (e.g., Subscriber1/Network A) is in a connected state, particularly in multi-SIM devices.
Innovation Solution
The method involves configuring the wireless communication device to manage multiple subscribers, with one subscriber in a connected state and another in an idle or inactive state. The device determines Multi-SIM Assistance Information (MAI) associated with the second subscriber and transmits this information to the first wireless communication node, enabling detection of paging messages across networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one subscriber is configured into a connected state with a first wireless communication node, then the connected state communication is maintained, but the detection of paging messages for another subscriber is blocked
Solution Approach 1:
The patent segments the monitoring functions by separating the paging detection task from the connected subscriber's active communication. The wireless communication device creates a logical separation where the first subscriber maintains connected state for data transmission while the second subscriber's paging detection operates independently through configured monitoring resources, allowing both functions to coexist without interference
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of configured monitoring resources that act as a mediator between the connected state subscriber and the paging detection function. These intermediary resources enable the device to receive and process paging messages for the second subscriber through the first wireless communication node without disrupting the first subscriber's connected state communication
2Difficulty of detecting and measuring
If multi-SIM assistance information is transmitted to enable paging detection, then paging message detection is enabled, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring monitoring resources and transmitting multi-SIM assistance information before paging detection is needed. The wireless communication device prepares the monitoring configuration in advance, establishing the capability to detect paging messages for the second subscriber while maintaining the first subscriber's connected state, thus avoiding complex runtime decision-making
Solution Approach 2:
The patent utilizes parameter changes by modifying the operational parameters of the wireless communication device to support multi-SIM functionality. The device adjusts its monitoring parameters, resource allocation, and state management based on the configured monitoring resources, enabling paging detection for one subscriber while maintaining connected state for another through dynamic parameter adjustment

AI summary
A system and method for detecting the paging of another Subscriber when one Subscriber is in a connected state. The system and method includes configuring, by a wireless communication device, a first subscriber of the wireless communication device into a connection state with a first wireless communication node; configuring, by the wireless communication device, a second subscriber of the wireless communication device into an idle state or an inactive state, wherein the second subscriber is associated with a second wireless communication node; determining, by the wireless communication device, Multi-Subscriber Identification Module (SIM) assistance Information (MAI) that is associated with the second subscriber of the first wireless communication node; and transmitting, by the wireless communication device, the MAI to the first wireless communication node.
