Edge Computing Data Transmission via DNS-Based Terminal Wake-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile edge computing scenarios, devices cannot actively transmit data to terminals in idle mode without using connection-holding interface technologies of the application or transmission layer, limiting communication flexibility and service types.
Innovation Solution
A data transmission system that includes a MSISDN query module, a subscriber awareness module, and a traffic data transmit and temporary storage module, which use DNS queries to obtain IP addresses and manage data packet forwarding or storage based on terminal connectivity, allowing for active data transmission to idle terminals through a paging mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection-holding interface technologies of application layer or transmission layer are used to enable active data transmission to idle terminals, then data transmission capability is improved, but device complexity and protocol overhead increase
Solution Approach 1:
The patent introduces a gateway as an intermediary component that mediates between the device and the terminal. The gateway maintains the connection with the idle terminal and handles data forwarding, eliminating the need for the device to implement complex connection-holding protocols. The device simply sends data to the gateway, which then delivers it to the terminal, thus reducing device complexity while maintaining transmission capability.
Solution Approach 2:
The patent extracts the connection management function from the device and places it in the gateway. By separating the connection-holding responsibility from the data transmission function, the device can use simple protocols while the gateway handles the complex connection management with idle terminals, thus resolving the contradiction between transmission capability and device complexity.
2Reliability
If conventional connection-holding interface technologies are used, then active data transmission to terminals is enabled, but service type flexibility is reduced
Solution Approach 1:
The gateway acts as a universal intermediary that can handle multiple service types and protocols. By placing the connection management at the gateway level rather than requiring each device to implement specific connection-holding protocols, the system gains flexibility to support various service types while maintaining active transmission capability to idle terminals.
Solution Approach 2:
The gateway is designed as a universal component that can manage connections for different service types and protocols. This multi-functional approach allows the system to maintain active transmission capability across diverse services without limiting service type flexibility, as the gateway adapts to different protocol requirements centrally rather than requiring device-specific implementations.
Data Source
AI summary
A data transmission system and method thereof for edge computing are provided. A terminal mobile station international subscriber directory number (MSISDN) and a terminal IP of a target terminal are obtained with a domain name system (DNS) by a device providing communication services from the data transmission system. After data packets are sent to the data transmission system, if the target terminal is in an idle mode, a paging message is sent by a terminal wake-up module to enable the target terminal to return to a connected mode for communication. Before a connection is established between the data transmission system and the target terminal, downlink data packets can be temporarily stored, and the packets can be sent after the target terminal is in the connected mode. A computer readable medium for executing the data transmission method is also provided.
