Dual-SIM Uplink Resource Allocation for Padding Packet Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-SIM dual-active mobile phones face challenges with higher costs and power consumption due to two radio frequency transmit paths, and contention for a shared path leads to inefficient use of uplink resources, particularly when high-priority services send padding packages, causing data packet loss and affecting high-priority services.
Innovation Solution
Implementing an uplink resource allocation method for efficient data packet allocation method for efficient uplink resource management by prioritizing valid data transmission in dual-SIM dual-active scenarios, allocating resources based on service priorities and packet types, and managing retransmissions to avoid conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two radio frequency transmit paths are configured for dual-SIM dual-active, then uplink transmission reliability is improved, but device cost and power consumption increase
Solution Approach 1:
The patent merges the transmit paths by using a single radio frequency transmit path for both SIM cards, eliminating the need for two separate paths. This reduces device cost and power consumption while maintaining dual-SIM dual-active functionality through intelligent resource allocation and uplink conflict management mechanisms.
2Use of energy by moving object
If a shared radio frequency transmit path is used for dual-SIM dual-active, then device cost and power consumption are reduced, but uplink resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic uplink resource allocation where the system adaptively adjusts resource assignment based on real-time service priorities and data packet validity. When uplink conflicts occur, the system dynamically determines which service receives the transmit path based on priority levels and whether data packets are valid or padding, optimizing resource utilization efficiency under shared path constraints.
3Reliability
If high-priority services are allocated uplink resources preferentially, then service quality for high-priority services is improved, but data packet loss for low-priority services increases
Solution Approach 1:
The patent applies local quality differentiation by treating different data packets differently based on their validity and service priority. When a high-priority service has valid data to transmit, it receives the uplink resource; when it only has padding packages, the resource can be allocated to low-priority services with valid data. This localized decision-making reduces data packet loss for low-priority services while maintaining quality for high-priority services.

AI summary
This application provides an uplink resource configuration method. The method may be applied to user equipment that supports dual-SIM dual-active. In this method, after an uplink conflict occurs after uplink scheduling of a plurality of base stations is received, the user equipment that supports dual-SIM dual-active obtains a type of an uplink data packet of a service corresponding to each base station. When a current uplink data packet of a high-priority service is a padding package, the user equipment may preferentially allocate an uplink resource to a low-priority service to send an uplink data packet of the low-priority service, and does not allocate the uplink resource to the high-priority service.
