Small-Cell Base Station Multicast Streaming Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile streaming media solutions rely on macro networks, which occupy excessive communication resources due to their large coverage area and multiple users watching the same program, limiting personalized services.
Innovation Solution
Implementing a method and system using small-cell base stations that receive request messages from terminals, forward them to streaming media sources, establish air interface broadcast physical channels, and convert streaming media data packets into multicast packets for personalized streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If broadcasting is performed on a macro network side, then a larger area can be covered and more users can be served, but too many communication resources are occupied and users have to watch the same program
Solution Approach 1:
The patent divides the macro network into multiple small-cell base stations, each serving a local area. Instead of one macro base station broadcasting to all users, multiple small cells segment the service area, allowing each cell to independently provide personalized streaming media services to its local users, thereby reducing overall communication resource occupation while maintaining wide coverage.
Solution Approach 2:
The patent enables each small-cell base station to provide customized streaming media services tailored to local user preferences. By allowing different programs to be broadcast in different small cells based on local demand, the system optimizes resource allocation locally rather than uniformly across the entire macro network, reducing wasted resources on programs no one watches.
2Adaptability or versatility
If broadcasting is performed on a macro network side, then more users can be served, but users have to watch the same program and personalized services are limited
Solution Approach 1:
The patent segments the user base by small-cell base station, allowing personalized service recommendations and program selection at the local level. Each small cell can independently manage its own streaming media content based on local user preferences, enabling personalization without requiring every user to receive customized broadcasts over the entire macro network, thus conserving communication resources.
3Productivity
If a macro network covers a larger area and bears many users, then more users can be served, but too many communication resources are occupied
Solution Approach 1:
The patent segments the large user base into multiple smaller groups, each served by a dedicated small-cell base station. This segmentation allows efficient resource allocation where each small cell manages its own communication resources independently, avoiding the resource exhaustion problem of a single macro base station serving too many users simultaneously.
Solution Approach 2:
The patent transitions from a two-dimensional macro network coverage model to a multi-layered architecture where small cells operate within the macro network framework. This dimensional change allows simultaneous service to many users across different spatial layers, increasing productivity without proportionally increasing communication resource consumption.
Data Source
AI summary
A method and a system for implementing mobile streaming media is provided by: receiving, by a small-cell base station, a request message sent by a terminal, where the request message carries a stream identifier corresponding to a streaming media program, and forwarding the request message to a streaming media source; then establishing, by the small-cell base station, an air interface broadcast physical channel, and mapping the air interface broadcast physical channel to the stream identifier; receiving, by the small-cell base station, a streaming media data packet sent by the streaming media source, and converting the streaming media data packet into a multicast packet; and sending, by the small-cell base station, the multicast packet to the terminal on the air interface broadcast physical channel.
