Application Slice Reservation for OTT QoS Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems struggle to effectively reserve resources for over-the-top (OTT) applications lacking explicit messages or commands, making it difficult to trigger resource reservation automatically.
Innovation Solution
A communication system with a data management repository module and control module that detects application program activation on a terminal device, allocates application slices, and reserves end-to-end resources based on quality of service requirements, including radio, core network application, and user plane resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If resource reservation is triggered by explicit messages or commands from the terminal device, then resource reservation can be effectively performed for applications with explicit triggers, but resource reservation cannot be automatically triggered for OTT applications lacking explicit messages or commands
Solution Approach 1:
The patent introduces an intermediary mechanism (packet detection module and application slice management module) that mediates between the terminal device and the network side. The terminal device sends packets with specific identification information, and the network side's packet detection module detects these packets to trigger resource reservation, eliminating the need for explicit trigger messages while enabling automatic resource allocation for OTT applications
Solution Approach 2:
The terminal device performs self-service by embedding identification information in the data packets it transmits. This allows the network side to automatically detect and trigger resource reservation based on the presence of these identification packets, without requiring the terminal device to send separate trigger messages or commands
2Adaptability or versatility
If network slice is allocated according to terminal device configuration file, then resource allocation can be standardized, but it cannot dynamically adapt to specific application program execution states
Solution Approach 1:
The patent applies preliminary action by pre-configuring identification information in the terminal device's configuration file that corresponds to different application slices. When an application runs, the terminal device embeds the corresponding identification information in packets, allowing the network side to quickly match and allocate the correct application slice without complex real-time analysis
Solution Approach 2:
The patent segments the network resources into multiple application-specific slices, each with its own identification information and resource characteristics. This segmentation allows different applications to be allocated to different slices based on their specific requirements, enabling fine-grained resource allocation while maintaining a relatively simple allocation mechanism
Data Source
AI summary
A communication system, is coupled to a terminal device through an air interface. The terminal device executes an application program. The communication system includes a data management repository module and a control module. The data management repository module is used to store a configuration file of the terminal device, and the configuration file reflects a quality of service (QOS) requirement of the terminal device. The control module is used to automatically detect an activation of the application program on the terminal device, and allocate at least one application slice to the application program of the terminal device according to the configuration file. The communication system reserves an end-to-end resource for the application program of the terminal device according to the QoS requirement of the terminal device, the end-to-end resource comprises a radio resource, a core network application resource and a core network user plane resource.
