Intermediate Network Node Reducing Wireless Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile applications, both native and web-based, experience significant latency when communicating with servers to obtain information, with Internet latency being a major contributor, leading to slow response times for users.
Innovation Solution
An intermediate network node in a wireless communications network receives application software to execute on behalf of a mobile terminal, allowing it to provide requested services directly to the terminal, thereby reducing the need for direct communication with potentially slow web servers and minimizing Internet latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If mobile terminals communicate directly with web servers to access services, then service accessibility is maintained, but latency increases significantly due to Internet round-trip time
Solution Approach 1:
The patent introduces an intermediate network node as a mediator between the mobile terminal and the web server. This node receives service requests from the terminal, executes application software locally, and provides services without requiring direct communication with the remote server for subsequent requests. This intermediary approach reduces latency by eliminating repeated Internet round-trips while maintaining service accessibility.
Solution Approach 2:
The patent implements preliminary action by having the intermediate network node download and execute application software in advance before actual service requests are made. The application software is prepared and stored at the network node, enabling it to process service requests locally without waiting for remote server responses, thus significantly reducing perceived latency for the user.
2Speed
If application software is executed at the intermediate network node, then service response speed improves, but the network node must handle more processing load
Solution Approach 1:
The patent applies copying by having the intermediate network node receive and execute a copy of the application software that replicates the functionality of the remote server's service. Instead of the terminal repeatedly contacting the remote server, a local copy of the application is executed at the network node, enabling fast local processing while the original server remains in the background for initial software provisioning.
3Loss of time
If the intermediate network node provides services locally, then Internet latency is minimized, but radio resources must be managed carefully to avoid waste
Solution Approach 1:
The patent implements dynamics by making the service provision mechanism adaptive. The intermediate network node dynamically determines whether to execute application software locally or forward requests to the remote server based on current conditions. This dynamic approach allows the system to optimize between local processing (for speed) and remote processing (for resource efficiency), preventing radio resource waste while maintaining low latency when needed.
Data Source
AI summary
A method and intermediate network node provide a service requested by a mobile terminal in a wireless communications network. The intermediate network node has a processing unit and a memory containing instructions executable by the processing unit. The intermediate network node receives a first request for a service from the mobile terminal, and receives application software configured to be executed at the intermediate network node to provide the mobile terminal with at least part of the requested service. The intermediate network node provides the mobile terminal with the at least part of the requested service. A subsequent request related to the service of the mobile terminal terminates at the intermediate network node, and provides the mobile terminal with at least part of the service requested in the subsequent request on behalf of a provider of the service.
