Network-Side Agent for Feed-Based Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Feed-based automatic distribution of content to mobile terminals in mobile networks leads to increased bandwidth consumption due to large feed sizes, frequent updates, and point-to-point transmission, which can result in inefficient bandwidth usage and redundant data transmission.
Innovation Solution
A network component with a network-side agent that manages feed requests and transmissions, using a feed cache and content cache to reduce redundant data and optimize bandwidth usage by generating feed requests periodically, transmitting only new content, and selecting communication links like multicast or broadcast for efficient data delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile terminals periodically retrieve feeds from feed servers, then content distribution is achieved, but bandwidth consumption increases
Solution Approach 1:
A network-side agent is introduced as an intermediary between mobile terminals and feed servers. This agent consolidates multiple feed retrieval requests into a single request, acting as a mediator that reduces the number of individual connections and data transmissions required, thereby lowering bandwidth consumption while maintaining content distribution functionality.
Solution Approach 2:
The patent merges multiple feed retrieval operations into a single consolidated request handled by the network-side agent. Instead of each mobile terminal making separate periodic requests to feed servers, the agent combines these requests and handles them centrally, reducing redundant data transmissions and optimizing bandwidth usage.
2Loss of information
If feeds contain all items including old content, then complete content history is available, but feed size becomes large
Solution Approach 1:
The network-side agent performs preliminary actions by pre-fetching and caching feed data before mobile terminals need it. The agent maintains a local copy of feeds and can provide content history from cached data, reducing the need for terminals to retrieve complete large feeds while still accessing historical content when needed.
Solution Approach 2:
The patent extracts only the necessary content information from complete feeds and presents it to mobile terminals through the network-side agent. The agent selectively retrieves and transmits only the portions of feed data that mobile terminals actually need, rather than transmitting entire large feeds, thereby reducing data quantity while preserving access to content history.
3Reliability
If feeds are transmitted in point-to-point fashion to each terminal, then individual delivery is ensured, but bandwidth consumption increases
Solution Approach 1:
The network-side agent provides universal functionality by serving multiple mobile terminals through a single interface to the feed server. The agent can simultaneously fulfill requests from multiple terminals using cached feed data, making the system multi-functional and reducing the need for separate point-to-point transmissions for each terminal.

AI summary
For improving feed-based automatic distribution of content to a mobile terminal via a mobile network, a network component (150) comprises a network-side agent (160). The network-side agent (160) manages the feed-based automatic transmission of content to the mobile terminal and is configured to periodically generate a feed request to a feed server, to receive a requested feed from the feed server in response to the feed request, and to transmit the received feed to the mobile terminal. The network component (150) may also comprise a cache memory (164) for storing copies of feeds and contents and a proxy for processing feed requests and content requests received from the mobile terminal (110).
