Multi-SIM Paging Target Indication for Lower UE Decoding Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems with multiple Subscriber Identity Modules (SIMs) face inefficiencies in paging mechanisms, leading to connection timeouts and increased processing complexity and power consumption due to treating each SIM as independent UEs, without a unified standard.
Innovation Solution
A method and device for a base station to determine a target SIM within a user equipment (UE) and send a paging target indication, allowing the UE to receive and process paging instructions efficiently, reducing decoding time and power consumption by utilizing a short message with specific indicator bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network treats each SIM in multi-SIM UE as independent UEs for paging, then paging can be performed for each SIM separately, but the connection between the SIM and base station may timeout and processing complexity increases
Solution Approach 1:
The patent merges the paging processes of multiple SIMs into a unified procedure. The base station sends a single paging message containing paging indicators for multiple SIMs simultaneously, rather than treating each SIM as an independent UE requiring separate paging procedures. This reduces processing complexity while maintaining connection reliability through unified resource allocation and timing management.
Solution Approach 2:
The paging message structure is designed with universal applicability to handle multiple SIMs. The paging indicator field can indicate paging for one or more SIMs using the same message format, allowing the base station to page multiple SIMs with a single transmission rather than requiring separate specialized procedures for each SIM.
2Reliability
If paging messages are sent to each SIM separately in multi-SIM UE, then each SIM can be paged independently, but power consumption and processing complexity of the UE increase
Solution Approach 1:
The UE receives a single combined paging message that contains paging indicators for multiple SIMs, rather than separately processing multiple paging messages. This reduces the number of decoding operations and processing steps required, directly lowering power consumption while maintaining reliable paging delivery for all SIMs through the unified message structure.
3Measurement precision
If multiple paging messages are processed for multiple SIMs, then each SIM can be paged accurately, but decoding time and processing complexity increase
Solution Approach 1:
The patent combines paging indicators for multiple SIMs into a single paging message with a unified structure. The base station sets specific bits in the paging indicator to indicate which SIMs are being paged, allowing the UE to decode one message and determine the paging status of multiple SIMs simultaneously, rather than separately decoding multiple messages for each SIM.

AI summary
An information processing method includes a base station determining a first subscriber identity module (SIM) to be paged of a user equipment (UE), the UE being configured with at least the first SIM and a second SIM, and the base station sending a paging target indication of the UE to a target SIM of the UE, the target SIM being the first SIM or the second SIM, and the paging target indication being configured to indicate paging the first SIM.
