Method, Apparatus and Computer Program Product for Providing Service Continuity for Multicast and Broadcast Service - A simplified explanation of the abstract

This abstract first appeared for US patent application 18249799 titled 'Method, Apparatus and Computer Program Product for Providing Service Continuity for Multicast and Broadcast Service

Simplified Explanation

The present patent application is related to wireless communication technology and specifically focuses on providing service continuity for Multicast and Broadcast Service (MBS). The application describes a method and apparatus for retransmitting missing data units in MBS sessions to ensure uninterrupted service for users.

• The patent application addresses the need for service continuity in Multicast and Broadcast Service (MBS) in wireless communication.
• It proposes a method for retransmitting missing Packet Data Units (PDUs) in MBS data that were not received by the user equipment (UE).
• The method involves receiving a request from the UE for retransmitting the missing PDUs associated with an MBS session.
• Based on the request, the first RAN node handles the retransmission of the missing PDUs to ensure the uninterrupted delivery of MBS data to the UE.

Potential Applications

This technology has potential applications in various wireless communication systems that utilize Multicast and Broadcast Service (MBS). Some potential applications include:

• Broadcasting live events or multimedia content to a large number of users simultaneously.
• Providing software updates or firmware upgrades to multiple devices simultaneously.
• Delivering real-time information or emergency alerts to a wide range of users in a specific area.

Problems Solved

The technology described in this patent application addresses the following problems:

• Ensuring uninterrupted service for Multicast and Broadcast Service (MBS) in wireless communication systems.
• Handling missing data units in MBS sessions to prevent service disruptions for users.
• Efficiently retransmitting missing Packet Data Units (PDUs) to minimize data loss and maintain service continuity.

Benefits

The proposed method and apparatus for providing service continuity for Multicast and Broadcast Service (MBS) offer several benefits, including:

• Improved user experience by minimizing service disruptions and ensuring uninterrupted delivery of MBS data.
• Efficient utilization of network resources by selectively retransmitting missing PDUs instead of retransmitting the entire MBS session.
• Enhanced reliability and robustness of wireless communication systems utilizing MBS technology.

Original Abstract Submitted

The present application generally relates to wireless communication technology. More particularly, the present application relates to a method and apparatus for providing service continuity for Multicast and Broadcast Service (MBS). The present application also relates to computer program product adapted for the same purpose. According to one embodiment of the present application, a method in a first RAN node for providing service continuity for Multicast and Broadcast Service (MBS) comprises: receiving () from a UE a request for retransmitting one or more missing Packet Data Units (PDUs) in MBS data associated with an MBS session previously transmitted from a second RAN node to the UE; and handling () retransmission of the missing PDUs based on the request.
