Solution Overview
Problem
In the context of 5G network deployment, terminals with multiple Subscriber Identity Modules (SIMs) frequently switch from 5G to 4G networks due to inadequate 5G coverage, leading to service interruptions.
Innovation Solution
An information processing method and apparatus for user equipment and base stations that manage multiple SIMs, where configuration information is received for performing measurements on a secondary network with idle SIMs, and measurements are conducted when the signal quality of the primary network meets specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If 5G terminals with multiple SIMs preferentially use 5G network for communication, then network speed and capacity are improved, but service interruption increases due to frequent switching to 4G network when 5G coverage is insufficient
Solution Approach 1:
The patent applies preliminary action by having idle SIMs perform measurements on 4G networks in advance before 5G service interruption occurs. When the primary SIM is connected to 5G, secondary SIMs proactively measure 4G signal quality, so that when 5G coverage becomes insufficient, the terminal can immediately switch to 4G using the pre-measured secondary SIM, avoiding service interruption.
2Ease of operation
If multiple SIMs communicate independently with the network without cooperation, then each SIM can be managed separately, but network stability deteriorates when primary network signal quality deteriorates
Solution Approach 1:
The patent merges the operations of multiple SIMs by establishing cooperative relationships between them. The primary SIM handles active communication while secondary SIMs perform measurement tasks, and they work together through coordinated switching. This combination allows the terminal to maintain SIM management flexibility while improving network stability through collaborative operation.
Solution Approach 2:
The patent implements feedback mechanisms where measurement results from idle SIMs are continuously monitored and fed back to the network management system. When signal quality of the primary network deteriorates below threshold values, this feedback triggers automatic switching to alternative networks using secondary SIMs, maintaining network stability while preserving SIM management flexibility.
3Reliability
If 5G coverage is expanded to eliminate the need for switching to 4G, then service continuity is improved, but infrastructure cost and deployment complexity increase
Solution Approach 1:
The patent applies self-service by enabling terminals to autonomously manage their own network switching without requiring extensive network infrastructure changes. The terminal uses its own secondary SIMs to perform measurements and automatically switches to 4G networks when 5G coverage is insufficient, achieving service continuity through device-level self-service rather than network-level infrastructure expansion.

AI summary
Provided in embodiments of the present disclosure are an information processing method, an information processing apparatus, a user equipment, a base station, and a storage medium. The method is applied to a user equipment, and the user equipment includes a first Subscriber Identity Module (SIM) in a connected state and one or more second SIMs in an idle state. The information processing method includes: receiving configuration information for performing a measurement on a second network with the second SIMs; and in response to that signal quality of a first network accessed by the first SIM satisfies a measurement condition, performing a measurement on a second network with one of the second SIMs based on the configuration information. The information processing method is beneficial to greatly reduce the time delay caused by the user equipment switching the network.
