Mobile Broadcast Service Packet Distribution with Version Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile broadcast services, existing methods inefficiently distribute service packets due to oversized content transmission, occupying limited resources and reducing transmission efficiency.
Innovation Solution
The method involves constructing and distributing service packets with header information containing integrality and version information, allowing for refined updates and efficient data management by categorizing packets as integral or update packets, and segmenting content for targeted distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all service packet contents are transmitted in real time via broadcast or interactive service units, then complete service data can be delivered to user terminals, but transmission efficiency decreases due to oversized packets and redundant data occupation of limited transmission resources
Solution Approach 1:
The service packet is segmented into header information and content information, with the header containing integrality information and version information. This segmentation allows the system to transmit only necessary update data rather than complete packets, resolving the contradiction between delivering complete service data and maintaining transmission efficiency.
Solution Approach 2:
The patent extracts and transmits only the necessary content information based on integrality information and version information, rather than transmitting complete service packets. This extraction principle enables efficient updates by sending minimal necessary data while maintaining service completeness.
2Reliability
If complete service packets are distributed to all user terminals, then all terminals receive full service functionality, but network resources are wasted due to redundant transmission of data already existing in terminals
Solution Approach 1:
User terminals pre-store service packet header information including integrality information and version information. This preliminary action enables terminals to efficiently determine whether they need to receive complete packets or only updates, reducing redundant network resource consumption while maintaining service functionality.
Solution Approach 2:
The system uses version information and integrality information as feedback mechanisms to determine transmission needs. Terminals compare their stored version information with transmitted version information to feedback whether they require complete packets or only incremental updates, optimizing network resource utilization.
3Manufacturing precision
If version information and integrality information are added to service packets, then update control precision is improved, but packet overhead increases
Solution Approach 1:
The patent applies partial action by adding only essential header information (integrality and version information) rather than complete service packet data. This minimal overhead approach provides sufficient update control precision without excessive packet size increase, as the header information enables intelligent update determination without requiring transmission of full packet contents.
Data Source
AI summary
A method and a system for distributing a mobile broadcast service are provided. The method includes: adding header information into broadcast service contents, the header information comprising integrality information and version information of a service packet containing the broadcast service contents; distributing the service packet to a user terminal; updating or accepting, by the user terminal, its own service data by use of the service packet in accordance with the integrality information and version information of the service packet. The method and the system according to the embodiments in the present invention may bring about higher transmission efficiency of data packet.
