Multi-SIM RRC Signaling for Paging Collision Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-SIM terminals are not recognized as having multiple SIMs by communication networks, leading to inefficiencies such as resource waste, paging collisions, and disrupted communication due to lack of coordination among SIMs.
Innovation Solution
A method for a terminal to send indication information about its multiple SIMs during the RRC connection process, allowing the base station to recognize and coordinate communication resources accordingly, using RRC signaling to enhance transparency and reduce interaction complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the network treats different SIMs as independent terminals without interconnection, then each SIM can communicate independently, but systematic paging collisions and communication coordination failures occur
Solution Approach 1:
The patent segments the terminal identification by introducing separate TMSI identifiers for each SIM card (first TMSI for first SIM, second TMSI for second SIM). This segmentation allows the network to treat each SIM independently for identification purposes while enabling coordinated management through the association relationship between SIMs and their corresponding TMSIs, thereby preventing paging collisions while maintaining independent communication capabilities.
2Device complexity
If the terminal does not provide indication information about multiple SIMs, then the RRC connection process remains simple, but the base station cannot coordinate communication resources among multiple SIMs
Solution Approach 1:
The patent applies preliminary action by having the terminal send indication information about multiple SIMs during the RRC connection establishment process. This early notification allows the base station to prepare coordinated communication resource allocation before actual data transmission begins, improving resource coordination efficiency without significantly increasing the complexity of the connection process.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal provides indication information about its multi-SIM configuration to the base station, and the base station responds with appropriate resource allocation decisions. This feedback loop enables efficient communication resource coordination while maintaining a relatively simple overall process structure.
3Quantity of substance
If the network lacks information about multiple SIMs configuration, then signaling overhead is minimized, but communication transparency and coordination among SIMs are reduced
Solution Approach 1:
The patent applies local quality by introducing targeted indication information elements specifically for multi-SIM configuration at appropriate layers of the communication protocol. Rather than fundamentally changing the entire signaling structure, the patent adds localized information elements that provide necessary SIM configuration details only where needed, maintaining communication transparency while minimizing overall signaling overhead.

AI summary
A method for information transmission is provided, which is applicable to a terminal and includes sending indication information that the terminal has multiple SIMS to a base station in a process of establishing a radio resource control (RRC) connection. Using the RRC signaling to carry request content indication information can improve the utilization efficiency of the RRC signaling, reduce the interaction complexity caused by the newly added signaling and reduce the development workload.
