Multi-SIM Paging Cause Grouping for Collision-Resilient Wireless Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems with multiple subscriber identity modules (multi-SIM devices) face challenges in managing paging collisions and inefficient signaling due to the lack of clear paging cause indications, leading to increased overhead and reduced coverage.
Innovation Solution
Implementing techniques to add a common paging cause value, optimize paging cause signaling by grouping records with the same cause, and indicate multiple UE IDs to avoid collisions, along with network support notifications for multi-SIM switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If paging cause indication is included in every paging message, then paging cause information is complete and accurate, but signaling overhead increases
Solution Approach 1:
The patent combines multiple paging records with the same paging cause into a single grouped paging record. Instead of sending separate paging messages for each record, the system groups them and includes the paging cause indication once for the group, thereby reducing redundant signaling while maintaining complete paging cause information.
Solution Approach 2:
The patent introduces a universal paging cause indication field that can serve multiple paging records simultaneously. This field acts as a common identifier for grouped records, allowing the same paging cause information to be applied across multiple records without repeating the indication for each one.
2Reliability
If multiple UE IDs are assigned to avoid paging collisions, then paging reliability improves, but device complexity increases
Solution Approach 1:
The patent segments the paging process by assigning different UE IDs to different paging occasions or groups. Each UE ID is used in specific scenarios or time windows, dividing the complex multi-UE ID management into manageable segments that reduce overall system complexity while maintaining reliability.
Solution Approach 2:
The patent implements dynamic UE ID selection where the system can switch between different UE IDs based on current paging conditions, collision detection, and network state. This dynamic approach allows the system to adapt to changing conditions without requiring complex static management of all possible UE ID combinations.
3Productivity
If paging records are grouped by common cause, then signaling efficiency improves, but processing complexity at network node increases
Solution Approach 1:
The patent performs preliminary grouping of paging records by common cause at the network node before transmission. By pre-organizing records into groups with shared paging causes, the system reduces the complexity of individual record processing during actual paging operations, as the grouping structure is already established and can be efficiently transmitted.

AI summary
This patent document describes, among other things, techniques, and apparatuses for providing multiple network connections to improve wireless network efficiency and performance. In one aspect, a method of wireless communication is disclosed. The method includes determining, by a network node, whether to include a paging cause indication in a paging message based on a rule. The method further includes transmitting, by the network node, the paging message according to the determining, wherein the rule specifies that: in case that the paging message is being transmitted due to a common paging cause, the paging cause indication is omitted, and in case that the paging message is being transmitted due to a different paging cause that is different from the common paging cause, the paging message is transmitted by indicating the different paging cause in the paging cause indication.
