Dynamic Connection Priority for Voice and Data Network Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LTE wireless networks face inefficiencies in providing voice services over small cell networks, which are typically optimized for data services, leading to suboptimal performance for time-sensitive communications.
Innovation Solution
Implementing dynamic connection priority information to manage network connectivity, allowing user equipment to temporarily switch from a small cell network to a macro cell network for voice communications, using distinct connection priority information to prioritize frequency bands and network selection based on communication type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If small cell networks are used to provide both data and voice services, then network resource utilization is improved, but service quality deteriorates for time-sensitive voice communications
Solution Approach 1:
The system dynamically adjusts connection priority information based on service type. When voice service is detected, the macro cell frequency is prioritized; when data service is detected, the small cell frequency is prioritized. This dynamic adjustment allows the network to adapt resource allocation to service requirements, ensuring high-quality voice communication while maintaining efficient data service on small cells.
2Reliability
If macro cell networks are used for all communications, then service quality is improved, but network resource utilization deteriorates due to unnecessary switching
Solution Approach 1:
The system applies different connection priorities to different frequency bands based on service type. For voice services, macro cell frequency is given high priority to ensure quality. For data services, small cell frequency is given high priority to optimize resource utilization. This localized quality adjustment ensures each service type connects to the most appropriate network resource.
Solution Approach 2:
The user equipment autonomously determines service type (voice or data) and self-adjusts connection priority without requiring manual intervention or complex network control signaling. The device monitors its own communication needs and dynamically switches priority configurations, reducing signaling overhead and improving response speed.
3Reliability
If dynamic connection priority switching is implemented, then service quality is improved, but device complexity increases
Solution Approach 1:
The user equipment autonomously monitors service type and self-adjusts connection priority without requiring complex network control mechanisms. The device independently determines whether voice or data service is active and switches priority configurations accordingly, reducing the need for complex network-side management and signaling.
Solution Approach 2:
The system changes the priority parameter of frequency bands based on service type detection. When voice service is detected, the macro cell frequency priority is increased; when data service is detected, the small cell frequency priority is increased. This simple parameter adjustment mechanism achieves service quality improvement without complex structural changes.

AI summary
User equipment receives first connection priority information. In accordance with the first connection priority information, the mobile communication device establishes a first wireless communication link between the user equipment and a first wireless network to communicate first communications. A controller/management resource provides notification of second connection priority information to be used instead of the first connection priority information. In response to detecting a trigger event in which the user equipment is operated to communicate second communications, the user equipment uses the second connection priority information as a replacement to the first connection priority information to establish a second wireless communication link connecting the user equipment to the second network instead of the first network.
