Multi-SIM Terminal RF Chain Configuration for Network Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM terminals face challenges in smoothly transitioning between standby and connection modes across different networks due to resource conflicts and inefficient use of RF chains, leading to difficulties in monitoring paging and maintaining connections.
Innovation Solution
A method where a terminal requests configuration changes for its RF chains, including deactivation, scheduling gaps, or frequency band changes, to manage resource allocation and prevent collisions, by communicating with base stations to adjust serving cell configurations and capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal uses multiple RF chains to communicate with multiple networks simultaneously, then network connectivity and service reliability are improved, but resource conflicts and collisions between RF chains occur leading to operation difficulties
Solution Approach 1:
The patent implements dynamic configuration of serving cells associated with RF chains based on communication needs. The terminal can request and the network can adjust the configuration (activation, deactivation, scheduling gaps) of serving cells dynamically to adapt to changing communication requirements of multiple networks, resolving resource conflicts while maintaining connectivity.
Solution Approach 2:
The patent changes the configuration parameters of serving cells associated with RF chains. By modifying parameters such as cell activation state, scheduling gap patterns, and frequency band allocations, the system optimizes RF chain resource allocation to prevent collisions while maintaining reliable multi-network connectivity.
2Reliability
If a terminal monitors paging and maintains connections across multiple networks, then service reliability is improved, but resource allocation becomes inefficient leading to operation difficulties
Solution Approach 1:
The patent applies preliminary action by configuring serving cell parameters in advance based on predicted communication needs. The terminal can request pre-configuration of serving cells for upcoming communication requirements, and the network can prepare appropriate configurations before actual communication needs arise, improving both reliability and efficiency.
Solution Approach 2:
The system dynamically adjusts serving cell configurations based on actual communication needs. By activating or deactivating serving cells, adjusting scheduling gap patterns, or changing frequency band allocations in real-time, the system optimizes resource allocation efficiency while maintaining service reliability across multiple networks.
3Object-generated harmful factors
If a terminal requests configuration changes for RF chains to manage resource allocation, then resource conflicts are reduced, but device complexity increases
Solution Approach 1:
The terminal autonomously identifies resource conflicts and generates requests for serving cell configuration changes without requiring complex external coordination. The terminal can self-manage its RF chain resource allocation by requesting appropriate serving cell configurations from the network, reducing resource conflicts while keeping device complexity manageable.
Solution Approach 2:
The system implements feedback mechanisms where the terminal reports its communication needs and resource conflict situations to the network, and the network responds with appropriate serving cell configuration adjustments. This feedback loop enables automated conflict resolution without requiring complex manual configuration management.
