MIXED MODE MULTICAST ARCHITECTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18519409 titled 'MIXED MODE MULTICAST ARCHITECTURE
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications, specifically focusing on a multicast architecture that allows for flexible switching between unicast and multicast operations, supporting various traffic types such as Internet Protocol and Ethernet traffic.
- Transmitting data over shared multicast radio bearers (MRBs) and/or specific data radio bearers (DRBs)
- Implementing a multicast user plane function (UPF) to deliver multicast data to a base station
- Handling multicast data from different radio access networks (RANs)
- Protecting multicast data by creating a group key and encrypting the data sent over MRBs using the group key
- Transitioning multicast data from a source RAN to a target RAN
Potential Applications
- Enhanced multimedia streaming services
- Efficient content distribution in large-scale networks
- Improved group communication in IoT devices
Problems Solved
- Efficient utilization of network resources for multicast transmissions
- Seamless transition between unicast and multicast operations
- Enhanced security for multicast data transmission
Benefits
- Increased network efficiency and scalability
- Enhanced data delivery for multicast applications
- Improved security and privacy for multicast communications
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A multicast architecture may support flexible change between unicast and multicast operations and may support additional traffic types (e.g., Internet Protocol and Ethernet traffic). For example, the multicast architecture may include transmitting data over a shared multicast radio bearer (MRB) and/or specific data radio bearers (DRBs), a multicast user plane function (UPF) for supplying the multicast data to a base station, multicast data from different radio access networks (RANs), protecting the multicast data through creating a group key, ciphering the multicast data sent on the MRB using the group key, and transitioning the multicast data from a source RAN to a target RAN.
