Dual-USIM Terminal Resource Allocation for Simultaneous Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication systems with multiple USIM cards, only one card can occupy resources, leading to poor user experience as the other card cannot perform services, resulting in inefficient service delivery.
Innovation Solution
A method to determine the transmission capability of each USIM card and adjust resource allocation based on service requirements, allowing simultaneous service performance by both cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one USIM card exclusively occupies resources, then resource allocation is simplified, but the other USIM card cannot perform services, resulting in low service efficiency
Solution Approach 1:
The patent implements dynamic resource allocation where the terminal device negotiates transmission capability information (single communication duration and periodicity) with the network for each USIM card based on actual service requirements. This allows the resource allocation to adapt dynamically between single-card and multi-card scenarios, resolving the contradiction between allocation simplicity and service efficiency.
Solution Approach 2:
The patent changes the parameter representation from binary (one card active/other inactive) to continuous parameters (single communication duration and periodicity). By negotiating these parameters with the network, the system can flexibly adjust resource allocation to match service demands, enabling both cards to operate simultaneously when needed while maintaining simplicity when only one card is active.
2Productivity
If one USIM card stops working to free resources, then resources become available for the other card, but service continuity is interrupted, resulting in poor user experience
Solution Approach 1:
The patent performs preliminary negotiation of transmission capability information before actual service transmission begins. The terminal device determines the single communication duration and periodicity in advance and communicates this with the network, ensuring resources are pre-allocated and prepared. This preliminary action prevents service interruption by establishing resource guarantees before the other card needs to activate.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal device reports transmission capability information to the network, and the network responds with resource allocation decisions. This closed-loop feedback ensures that resource allocation adapts to actual service needs while maintaining service continuity, as the network can adjust allocations based on reported capabilities without interrupting ongoing services.
3Adaptability or versatility
If both USIM cards attempt to use resources simultaneously, then service coverage is improved, but resource coordination becomes complex, leading to potential data loss
Solution Approach 1:
The patent creates a universal resource allocation framework that handles both single-card and multi-card scenarios through the same negotiation mechanism. The transmission capability information (single communication duration and periodicity) serves as a universal parameter that works regardless of how many cards are active, simplifying coordination while enabling flexible service coverage.
Solution Approach 2:
The patent introduces transmission capability information as an intermediary that mediates between the terminal device and the network for resource coordination. Instead of directly managing complex multi-card resource conflicts, the system uses this intermediary parameter to convey negotiation results, which then guide resource allocation decisions, reducing coordination complexity while maintaining service coverage.

AI summary
Embodiments of this application provide a communication method and an apparatus. The method includes: When a first service needs to be newly established on a first USIM, a terminal device obtains transmission capability information. The transmission capability information includes single communication duration of the first USIM and single communication duration of a second USIM. The terminal device includes the first USIM and the second USIM. The terminal device determines, based on the transmission capability information and a requirement of the first service, whether to establish a first service. The requirement of the first service indicates a delay requirement of the first service. In this way, when a new service arrives, a solution of determining, based on the transmission capability information of the first USIM and the second USIM, whether to establish the new service is provided. Further, when the new service is established, it can be ensured that services of a plurality of USIM cards in the terminal device are simultaneously performed, so that a problem in the background that user experience is poor because a USIM exclusively occupies resources, and another USIM cannot be met to perform a service is resolved.
