Multi-SIM Priority Control for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-SIM terminals face service interruptions due to uncontrolled communication behavior, leading to reduced call quality and service continuity, especially when handling messages from different SIM cards with varying service types and priorities.
Innovation Solution
A data processing method and apparatus that determine the service type and configure priorities for each SIM card identifier on a terminal device, enabling the device to process communication services according to the configured priorities, thus improving service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal device controls communication behavior entirely itself in dual-mode and dual-standby, then the terminal can independently manage multiple SIM cards, but service continuity deteriorates due to uncontrolled communication behavior
Solution Approach 1:
The network side sends priority indication information back to the terminal device, creating a feedback mechanism where the terminal adjusts its communication behavior based on network priorities. This resolves the contradiction by enabling terminal independence while incorporating network control through feedback loops.
Solution Approach 2:
The communication behavior control is made dynamic through priority indication information that can change based on service types and network conditions. The terminal dynamically adjusts which SIM card to respond to based on real-time priority indications, resolving the static control issue.
2Productivity
If the terminal device receives all paging messages from all SIM cards, then complete message delivery is achieved, but call quality deteriorates due to harassing messages interrupting calls
Solution Approach 1:
Different quality treatment is applied to different service types through priority indication information. Voice calls receive high priority treatment while harassing messages receive low or no priority, enabling selective message delivery that maintains call quality while preserving complete message delivery capability.
Solution Approach 2:
The priority parameter of messages is changed and communicated to the terminal device through priority indication information. This parameter change enables the terminal to differentiate between important and unimportant messages, resolving the contradiction between complete delivery and quality maintenance.
3Adaptability or versatility
If the terminal device processes communication services without network control, then operational flexibility is improved, but service continuity deteriorates due to lack of coordinated control
Solution Approach 1:
Priority indication information acts as an intermediary between the network and terminal device. It translates network control intentions into actionable instructions for the terminal, maintaining flexibility while enabling coordinated control for service continuity.

AI summary
A data processing method performed by an electronic device includes obtaining subscription information of the terminal device in which are disposed at least two subscriber identity module (SIM) cards having corresponding SIM card identifiers. The subscription information is searched for and obtained according to each of the SIM card identifiers. Further, based on the obtained subscription information, a service type of a subscribed service for each of the SIM card identifiers is determined. A priority for the service type of the subscribed service for each of the SIM card identifiers is then determined and a notification message is transmitted to the terminal device. The notification message includes the priority determined for the service type of the subscribed service for each of the SIM card identifiers, and causes the terminal device to process a corresponding communication service according to the priority determined for each service type for each SIM card identifier.
