Broadcast Content Mapping to Unicast Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in seamlessly integrating and switching between unicast and multicast transmissions, as they require different setup and configuration parameters, leading to inefficiencies in service continuity and spectral efficiency.
Innovation Solution
A method and apparatus for determining whether content received in a broadcast type format should be transmitted using a unicast type format, mapping the content to a unicast reservation using broadcast protocol identifiers, and transitioning communication from broadcast to unicast format when necessary, to maintain service continuity and improve spectral efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If broadcast content is transmitted using broadcast type format, then multiple users can share the same channel using maximum transmission rate, but different setup and transmission configuration parameters are required for unicast and broadcast modes
Solution Approach 1:
The patent applies universality by enabling a single unicast channel to serve dual purposes: traditional unicast communication and broadcast content delivery. The system maps broadcast content to unicast channels using broadcast protocol identifiers, allowing the same channel infrastructure to handle both unicast and broadcast modes without requiring separate dedicated channels for each mode, thereby reducing configuration complexity while maintaining spectral efficiency.
Solution Approach 2:
The patent employs parameter changes by modifying the transmission mode parameter from broadcast to unicast while preserving broadcast protocol identifiers within the unicast frame structure. This allows the system to change the delivery mechanism (from one-to-many broadcast to one-to-one unicast) while maintaining compatibility with broadcast content formatting and identifiers, thus resolving the configuration parameter complexity issue.
2Productivity
If unicast transmission mode is used for broadcast content, then link efficiency is improved for point to point communication, but service continuity may be affected during mode switching
Solution Approach 1:
The patent applies preliminary action by pre-establishing unicast channels and mapping relationships before content transmission begins. The system pre-configures unicast channels with broadcast protocol identifiers and maintains mapping tables that associate broadcast content with corresponding unicast channels. This preliminary setup ensures that when mode switching is required, the transition can occur seamlessly without service interruption, as the unicast channel is already prepared and configured to receive broadcast content.
Solution Approach 2:
The patent uses an intermediary mechanism in the form of a mapping table or gateway that mediates between broadcast and unicast modes. This intermediary maintains the relationship between broadcast protocol identifiers and unicast channel parameters, enabling smooth transitions between modes. The intermediary ensures service continuity by managing the mapping relationships and coordinating the switching process, allowing the system to move between broadcast and unicast modes without disrupting ongoing content delivery.
3Adaptability or versatility
If broadcast content is mapped to unicast reservation, then content can be transmitted over unicast channel, but additional mapping and configuration is required
Solution Approach 1:
The patent applies merging by combining broadcast protocol identifiers with unicast frame structures. Instead of maintaining separate configuration systems for broadcast and unicast modes, the patent merges the broadcast content identification mechanism with the unicast transmission framework. The unicast frames incorporate broadcast protocol identifiers directly into their structure, allowing the system to treat broadcast content as a special case of unicast transmission. This merging reduces the number of separate mapping and configuration operations required, as the same unicast channel infrastructure handles both traditional unicast and broadcast content delivery.

AI summary
A method and apparatus providing broadcast content over a unicast channel. The method and apparatus may be configured to determine whether content received using a broadcast type format is to be transmitted using a unicast type format, and to map the content to a unicast reservation upon a determination that the content is to be transmitted using the unicast type format.
