ALTO Client Data Transmission Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ALTO technologies do not fully consider relevant network information, which restricts network transmission efficiency.
Innovation Solution
The ALTO client obtains transmission information of an access network exposed by an access network device and ALTO information provided by an ALTO server, integrating this information to perform data transmission optimization and select an appropriate end-to-end transmission path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing ALTO technologies are used, then network topology information can be provided to guide UE access, but network transmission efficiency is restricted due to incomplete network information consideration
Solution Approach 1:
The patent merges multiple information sources including ALTO information from the core network and access network transmission information from the access network device to create a comprehensive information set for the ALTO client, resolving the contradiction by combining previously separate information streams
Solution Approach 2:
The patent segments network information into distinct categories (ALTO information and access network transmission information) that are obtained through separate processes, then integrates them to achieve complete network information for optimized transmission path selection
2Reliability
If ALTO client uses only ALTO information from ALTO server, then optimization can be performed, but transmission path selection is suboptimal due to lacking access network transmission information
Solution Approach 1:
The access network device acts as an intermediary that exposes access network transmission information to the ALTO client, enabling the client to make more reliable transmission path decisions without directly complicating the core network architecture
Solution Approach 2:
The ALTO client is designed to process multiple types of information (ALTO information and access network transmission information) through a unified optimization process, making the system adaptable to comprehensive network information while maintaining operational simplicity

AI summary
According to an aspect, a method of data transmission optimization includes obtaining, by an application layer transmission optimization (ALTO) client, and based on a data network (DN), transmission information of an access network. The transmission information of the access network being exposed by an access network device to the DN. ALTO information that is provided by an ALTO server is obtained. The data transmission optimization of the ALTO client is performed based on the ALTO information and the transmission information of the access network. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
