Dual SIM Registration Delay Reduction via RF Resource Reallocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual SIM-supported electronic devices face delays in registering with a second communication network due to the need to reallocate RF resources after data transmission/reception with the first SIM, leading to unnecessary waiting times for retransmission of registration requests.
Innovation Solution
An electronic device with at least one processor and two SIMs, configured to complete registration for the first SIM, allocate RF resources to the second SIM for registration, and retransmit registration requests for the second SIM without waiting for a timer to expire, even if normal registration is not complete due to data transmission/reception with the first SIM.

Engineering Contradiction Analysis
1Reliability
If RF resources are reallocated to the second SIM after data transmission/reception with the first SIM, then the first SIM can maintain its communication connection, but the registration of the second SIM is delayed due to waiting time
Solution Approach 1:
The electronic device performs preliminary actions by checking whether data transmission or reception is possible before initiating the registration procedure for the second SIM. This allows the device to plan and prepare the registration process in advance, avoiding delays caused by unexpected resource reallocation. By assessing communication feasibility beforehand, the device can schedule registration at optimal times when RF resources will be available, thus reducing waiting time while maintaining connection reliability.
Solution Approach 2:
The electronic device dynamically adjusts the registration procedure based on the current state of data transmission or reception. The processor monitors the communication status and adaptively modifies the registration timing and resource allocation. This dynamic approach allows the system to optimize between maintaining active communication on the first SIM and completing registration on the second SIM, reducing unnecessary waiting periods while ensuring connection stability.
2Stability of the object's composition
If the electronic device waits for timer expiration before retransmitting registration request, then resource conflicts are avoided, but registration efficiency is reduced due to unnecessary waiting
Solution Approach 1:
The electronic device implements a feedback mechanism where the processor continuously monitors the status of data transmission or reception and uses this information to determine the optimal timing for registration request retransmission. Instead of blindly waiting for timer expiration, the device receives feedback about current resource availability and communication state, then makes intelligent decisions about when to retry registration. This feedback-driven approach eliminates unnecessary waiting while preventing resource conflicts, thereby improving registration efficiency without compromising stability.
Solution Approach 2:
Before retransmitting the registration request, the electronic device performs preliminary checks to determine whether data transmission or reception is currently possible. This preliminary action allows the device to proactively identify suitable moments for registration retry, avoiding both premature attempts that could cause resource conflicts and excessive waiting that would reduce efficiency. By checking conditions in advance, the device optimizes the retransmission timing to balance stability and productivity.

AI summary
An electronic device is provided. The electronic device includes at least one processor connected with a first subscriber identity module (SIM) and a second SIM and at least one radio frequency (RF) circuit. The at least one processor is configured to receive an RRC connection release message after radio resource control (RRC) connection with the first communication network to transmit/receive data in the state where the use of the at least one RF circuit is allocated to the first SIM, and retransmit a registration request message for the second communication network to the base station of the second communication network in the state where the use of the at least one RF circuit is allocated to the second SIM in response to the reception of the RRC connection release message.
