Multicast Router for Cellular Non-Cellular Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing broadcast services, particularly in identifying and delivering multimedia content to devices with limited or no cellular capabilities, as they often rely on cellular-enabled devices for multicast sessions, which can lead to inefficiencies in content distribution.
Innovation Solution
The system maps a multicast IP-based identifier to a broadcast technology identifier, allowing devices with or without cellular capabilities to join multicast sessions by selecting the appropriate radio access technology (RAT) and replicating data streams to multiple requesting devices, ensuring seamless content delivery across different technologies like CDMA and eMBMS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices without cellular capabilities rely on cellular-enabled devices for multicast sessions, then content distribution can be achieved, but network efficiency deteriorates and device complexity increases
Solution Approach 1:
The patent introduces a router as an intermediary device that receives multicast data from the network and redistributes it to devices without cellular capabilities. The router acts as a mediator between the cellular network and non-cellular devices, enabling content distribution without requiring the non-cellular devices to participate directly in cellular multicast sessions, thus improving network efficiency while maintaining versatility
Solution Approach 2:
The router is designed to handle multiple functions: receiving multicast data from cellular-enabled devices, buffering the data, and redistributing it to both cellular and non-cellular devices. This multi-functional approach allows a single device to serve multiple purposes, reducing the need for specialized infrastructure while improving overall system efficiency
2Adaptability or versatility
If multiple devices join the same multicast session, then content accessibility improves, but network resource consumption increases
Solution Approach 1:
The patent merges multiple device requests into a single multicast session by having the router aggregate demands from multiple devices and join them to the same upstream multicast session. This consolidation reduces redundant network traffic and resource consumption while maintaining accessibility for all requesting devices through the router's local redistribution capability
3Adaptability or versatility
If cellular-enabled devices are used to provide multicast content to non-cellular devices, then device compatibility improves, but system complexity increases
Solution Approach 1:
The patent extracts the complexity of cellular protocol handling and multicast session management from individual devices and concentrates it in the router. Non-cellular devices simply communicate with the router using standard protocols, while the router handles the complex tasks of interfacing with the cellular network, managing sessions, and coordinating content delivery, thereby reducing device complexity while maintaining compatibility

AI summary
Methods, systems, and devices are described for managing broadcasts of data in wireless communications. A request to join a multicast session is received. A plurality of broadcast technology based identifiers associated with the multicast session are received. Each broadcast technology based identifier identifies one of a plurality of radio access technologies (RATs) broadcasting the multicast session. One of the plurality of RATs is selected. A multicast stream of data associated with the multicast session is received from the selected RAT.
