COMMUNICATION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18166140 titled 'COMMUNICATION METHOD AND APPARATUS
Simplified Explanation
The patent application describes a communication method and apparatus for ensuring the security of multicast service data packet transmission. Here are the key points:
- The application introduces a method to determine the security state of a multicast Data Radio Bearer (DRB) in a PDU session and communicate it to a terminal.
- The security state includes information about whether integrity protection and/or confidentiality protection are activated for the multicast DRB.
- Based on the security state of the multicast DRB, a multicast PDCP (Packet Data Convergence Protocol) layer entity is configured for transmitting multicast service data.
- The application also addresses the security state of a unicast DRB, communicates it to the terminal, and modifies a unicast PDCP layer entity accordingly.
Potential applications of this technology:
- This technology can be applied in multicast communication systems, such as video streaming services, where ensuring the security of data transmission is crucial.
- It can be used in teleconferencing systems to protect the confidentiality and integrity of multicast data shared among participants.
- This technology can also be beneficial in IoT (Internet of Things) networks, where multicast communication is used for efficient data dissemination.
Problems solved by this technology:
- Ensures the security of multicast service data packet transmission by activating integrity protection and/or confidentiality protection.
- Provides a method to communicate the security state of multicast and unicast DRBs to the terminal, allowing the terminal to handle the received data accordingly.
- Enables efficient configuration of PDCP layer entities based on the security state, optimizing the transmission of multicast service data.
Benefits of this technology:
- Enhances the security of multicast service data transmission, protecting against unauthorized access and tampering.
- Allows terminals to handle multicast and unicast data differently based on the security state, improving overall system performance.
- Optimizes the configuration of PDCP layer entities, leading to efficient transmission of multicast service data.
Original Abstract Submitted
Embodiments of this application provide a communication method and an apparatus, to ensure a multicast service data packet transmission security requirement. An access device may determine a user plane security active state of a multicast DRB in a PDU session, and indicate the user plane security active state of the multicast DRB to a terminal, where the user plane security active state includes whether integrity protection is activated and/or whether confidentiality protection is activated. In addition, the access device configures a multicast PDCP layer entity based on the user plane security active state of the DRB for transmitting multicast service data. The access device may further determine a user plane security active state of a unicast DRB, indicate the user plane security active state to the terminal, and modify a unicast PDCP layer entity.
