Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-card mobile terminals, existing solutions fail to effectively coordinate wireless processing resources between SIM cards, leading to potential RA failures and inefficient use of terminal capacity, especially when one SIM card is already connected and another attempts to enter the connected state, resulting in resource conflicts and overheating.
Innovation Solution
A network configuration method where a multi-card mobile terminal generates and transmits access request information with a predefined capacity limitation indication to the network-side device, allowing the device to adjust network configuration accordingly to avoid exceeding terminal capacity limits.

Engineering Contradiction Analysis
1Productivity
If multiple SIM cards share common wireless processing resources in a multi-card mobile terminal, then resource utilization efficiency is improved, but resource conflicts and access failures occur when one SIM card is connected and another attempts to enter connected state
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the mobile terminal to flexibly adjust wireless processing resource distribution based on real-time network states of multiple SIM cards. The terminal dynamically determines resource allocation strategies (independent processing vs. coordinated processing) according to whether SIM cards are in connected, inactive, or idle states, thereby resolving resource conflicts while maintaining high utilization efficiency
Solution Approach 2:
The patent establishes a feedback mechanism where the mobile terminal reports terminal capability information and network state information to the network side, and the network side responds with coordinated processing configuration information. This closed-loop feedback enables the system to adapt resource allocation based on actual network conditions and terminal capabilities, preventing access failures while maximizing resource utilization
2Device complexity
If static division of communication processing link resources is implemented, then resource allocation is simplified, but terminal capacity cannot be fully utilized and carrier frequency conflicts occur
Solution Approach 1:
The patent replaces static resource division with dynamic resource allocation. The mobile terminal determines processing modes (independent or coordinated) based on real-time network states of multiple SIM cards, and the network side adjusts configuration information accordingly. This dynamic approach fully utilizes terminal capacity while avoiding carrier frequency conflicts between cards from the same operator
Solution Approach 2:
The patent changes resource allocation parameters dynamically based on network state. When SIM cards are in different states (one connected, another inactive), the terminal switches between independent processing mode and coordinated processing mode, adjusting resource allocation parameters to optimize terminal capacity utilization while preventing frequency conflicts
3Reliability
If dramatic division of resources is implemented to avoid conflicts, then resource conflicts are reduced, but terminal capacity is exceeded and access requests must be limited
Solution Approach 1:
The patent implements dynamic resource allocation that adapts to real-time network states, allowing the terminal to fully utilize its capacity without exceeding limits. The terminal determines whether to process SIM cards independently or in coordination based on their network states, and the network side provides appropriate configuration information, thereby avoiding both resource conflicts and capacity overload
Solution Approach 2:
The patent dynamically adjusts resource allocation parameters based on network state and terminal capability information. The terminal reports its capability to the network side, which then provides coordinated processing configuration information when needed, enabling the terminal to operate at optimal capacity without exceeding limits or causing access failures

AI summary
A multi-card mobile terminal, a network configuration method of a multi-card mobile terminal, and a non-transitory computer-readable medium are provided. The network configuration method includes the following. In response to a first network access state of a SIM card of a multi-card mobile terminal being a connected state and another SIM card of the multi-card mobile terminal requesting to access a target network, access request information of the another SIM card is generated and transmitted to a target network-side device, where the access request information includes a capacity limitation indication, and the capacity limitation indication is configured to indicate that a current terminal wireless capacity of the multi-card mobile terminal is limited. Network configuration information corresponding to the access request information transmitted by the target network-side device is received. The multi-card mobile terminal is configured according to the network configuration information.
