Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Priority Telecommunications Service (PTS) programs primarily focus on voice communications, lacking effective solutions for providing priority data transport during emergency or crisis situations when telecommunications networks are congested.
Innovation Solution
The implementation of a Priority Data Transport Service (PDTS) that allows authorized users to activate and deactivate on-demand priority data transport using User Equipment (UE) Route Selection Policy (URSP) rules and network slicing, ensuring priority data access over 3GPP core networks, excluding WiFi access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Priority Telecommunications Service (PTS) programs focus on voice communications, then voice call completion probability is improved, but data transport priority is lost
Solution Approach 1:
The patent extends priority service capabilities from voice-only to include both voice and data communications. The system provides priority access for multiple communication types (voice calls, data sessions, video calls) through a unified priority service framework, allowing the same priority mechanisms to serve multiple functions and communication modes.
Solution Approach 2:
The patent implements dynamic priority service activation and deactivation based on user needs and network conditions. Priority service can be turned on or off through user input, allowing flexible adaptation between voice-priority mode and data-priority mode, and enabling the system to respond dynamically to changing emergency or crisis situations.
2Productivity
If network resources are allocated to regular traffic, then network capacity is maximized, but emergency data transport reliability deteriorates
Solution Approach 1:
The patent segments network traffic into priority and non-priority streams using network slicing technology. Different virtual network slices are created to handle priority data traffic and regular traffic separately, allowing the network to allocate resources differently for each slice. This enables emergency data to be transmitted through dedicated priority slices while regular traffic uses standard slices, maintaining overall network capacity while ensuring emergency reliability.
Solution Approach 2:
The patent introduces priority indicators and network slice selection mechanisms as intermediaries between user equipment and the core network. These intermediaries mark priority data packets and route them through appropriate network slices, ensuring that emergency data receives preferential treatment without requiring complete network reconfiguration or sacrificing regular traffic handling capabilities.
3Reliability
If priority service is activated continuously, then data transport priority is maintained, but energy consumption increases
Solution Approach 1:
The patent implements on-demand priority service activation where users can turn priority service on or off based on specific emergency situations. Instead of continuous activation, priority service is periodically activated only when needed, reducing energy consumption during normal operations while ensuring priority capability is available when emergencies occur. The system monitors for emergency conditions and activates priority service accordingly.
4Adaptability or versatility
If WiFi access is included in priority service, then data access flexibility is improved, but priority guarantee reliability deteriorates
Solution Approach 1:
The patent applies different quality characteristics to different network access types. WiFi access and cellular network access are treated differently in terms of priority guarantee. Cellular networks with 3GPP core networks receive strong priority guarantees through network slicing and QoS mechanisms, while WiFi access provides supplementary flexibility without the same level of priority assurance. This local differentiation allows the system to maintain high reliability for critical communications while still offering flexible WiFi options when available.
Data Source
AI summary
Techniques, devices, and systems for implementing a Priority Data Transport Service (PDTS) are disclosed. The PDTS provides authorized devices and/or authorized users with on-demand, priority data transport (e.g., priority Internet access). For example, the PDTS allows authorized devices and/or authorized users to access the Internet, use mobile applications, and/or send and receive image data, video data, and text data in a prioritized manner, as compared to the regular (non-priority) Internet access that is provided to non-subscribers of the PDTS over commercial telecommunications networks. An authorized user may activate and deactivate the PDTS on demand. For instance, the PDTS may be activated during an emergency or crisis situation when networks may be congested, thereby providing the user with priority data transport (e.g., priority Internet access) in an emergency or crisis situation when a telecommunications network may be overloaded.
