Single-SIM Dual-Standby Terminal Dynamic Network Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-card dual-standby terminals waste resources and energy by maintaining an always-enabled radio frequency for the TD-SCDMA network even when there is no PS connection, due to the inefficient utilization of network resources.
Innovation Solution
A method for a single-card dual-standby terminal to initiate a data service connection request through a GSM network first, determining if the GPRS network's capacity is sufficient, and if not, switching to the TD-SCDMA network, ensuring the PS connection bearer is established on the most capable network, thereby optimizing resource use and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the TD-SCDMA network radio frequency is always enabled to ensure PS service connection capability, then the PS service connection reliability is improved, but the energy consumption and resource waste increase
Solution Approach 1:
The patent implements dynamic network selection by allowing the terminal to flexibly switch between GSM and TD-SCDMA networks based on real-time service requirements and network conditions. The terminal dynamically enables or disables radio frequencies and selects appropriate networks for CS or PS services, avoiding the need to keep all networks continuously active while ensuring service reliability when needed.
2Reliability
If the GSM network radio frequency is always enabled to maintain voice call service, then the CS service reliability is improved, but the energy consumption increases
Solution Approach 1:
The patent implements dynamic network selection by allowing the terminal to flexibly switch between GSM and TD-SCDMA networks based on real-time service requirements and network conditions. The terminal dynamically enables or disables radio frequencies and selects appropriate networks for CS or PS services, avoiding the need to keep all networks continuously active while ensuring service reliability when needed.
3Reliability
If the terminal camps on both GSM and TD-SCDMA networks simultaneously to ensure service continuity, then the service reliability is improved, but the device complexity and resource utilization efficiency worsen
Solution Approach 1:
The patent implements dynamic network selection by allowing the terminal to flexibly switch between GSM and TD-SCDMA networks based on real-time service requirements and network conditions. The terminal dynamically enables or disables radio frequencies and selects appropriate networks for CS or PS services, avoiding the need to keep all networks continuously active while ensuring service reliability when needed.
Solution Approach 2:
The terminal autonomously performs network selection and service channel allocation based on its own service requirements and network conditions. It automatically determines which network to use for CS or PS services without requiring complex network-side coordination, thereby reducing overall system complexity while maintaining service continuity.
4Device complexity
If the terminal uses GSM network for both CS and PS services to simplify network management, then the device complexity is reduced, but the network resource utilization efficiency worsens
Solution Approach 1:
The patent implements dynamic network selection by allowing the terminal to flexibly switch between GSM and TD-SCDMA networks based on real-time service requirements and network conditions. The terminal dynamically enables or disables radio frequencies and selects appropriate networks for CS or PS services, avoiding the need to keep all networks continuously active while ensuring service reliability when needed.
