Base Station Data Retrieval for Core Network Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods in mobile communications systems are inefficient in reducing core network bandwidth usage, as they often require multiple transmissions of the same data to different user terminals, leading to wasted bandwidth and increased latency.
Innovation Solution
A data transmission method where a base station retrieves and stores data based on identification information, allowing it to directly send matched data to user equipment, thereby eliminating the need for repeated requests to the network and reducing the establishment of multiple same links, and dynamically manages storage according to user requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video content is transmitted separately to each terminal through the core network in HTTP stream manner, then each terminal can receive video content, but core network bandwidth is wasted due to repeated transmission of same content
Solution Approach 1:
The patent merges multiple requests for the same video content into a single transmission through the core network. When the video server detects that multiple terminals request identical video content (identified by matching video IDs), it transmits the content once to a selected terminal while simultaneously providing other terminals with information to obtain the content from the first terminal, thereby combining multiple transmission paths into one efficient path.
Solution Approach 2:
The patent introduces terminals as intermediaries in the content delivery process. Instead of the video server directly transmitting content to each terminal separately, the first terminal that receives content becomes an intermediary that other terminals can access. The video server provides identification information enabling terminals to obtain content from this intermediary terminal, reducing core network bandwidth usage.
2Productivity
If video content is transmitted through multiple paths to different terminals, then each terminal receives content independently, but the system complexity increases due to multiple link establishments
Solution Approach 1:
The patent extracts the content delivery function from the core network path for subsequent terminals. After the first terminal receives content, the video server provides identification information to other terminals, enabling them to obtain content directly from the first terminal through device-to-device communication, thereby removing the need for these terminals to establish separate links through the complex core network infrastructure.
3Reliability
If the same video content is sent to multiple terminals separately, then each terminal gets the content, but the transmission time increases due to repeated core network traversal
Solution Approach 1:
The patent implements preliminary action by having the video server pre-provide identification information to terminals about where to obtain content. When multiple terminals request the same video content, the server first transmits to one terminal and immediately provides the other terminals with identification information pointing to the first terminal, enabling them to obtain content directly without waiting for separate core network transmissions, thus reducing overall transmission latency.

AI summary
Embodiments of the present invention relate to the communications field, and provide a data transmission method, apparatus, and system, to reduce core network bandwidth resources occupied by data transmission. The method includes: receiving, by a first base station, a request message sent by a first device, where the request message carries identification information of requested data and identification information of the first device, and the first device includes a user equipment or a second base station; retrieving, by the first base station, in stored data according to the identification information of the requested data; and when matched data is retrieved, sending, by the first base station, the matched data to the first device according to the identification information of the first device, where the matched data refers to data that matches the identification information of the requested data.
