Point to Point and Point to Multipoint Switching with Service Continuity for Broadcast and Multicast Service - A simplified explanation of the abstract

This abstract first appeared for US patent application 18464582 titled 'Point to Point and Point to Multipoint Switching with Service Continuity for Broadcast and Multicast Service

Simplified Explanation

The patent application describes techniques for supporting switching between point-to-point and point-to-multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system.

• The techniques involve a cellular base station and a wireless device establishing a wireless link.
• The base station provides information to configure the wireless device to receive a broadcast or multicast service using a specific delivery type.
• The base station then transmits the service using the configured delivery type, and the wireless device receives the service accordingly.
• The base station can also provide information to configure the wireless device to switch to a different delivery type while maintaining service continuity.
• Once configured, the base station transmits the service using the new delivery type, and the wireless device receives the service accordingly.

Potential Applications

• This technology can be applied in wireless communication systems that support broadcast and multicast services.
• It can be used in scenarios where there is a need to switch between point-to-point and point-to-multipoint delivery for efficient service delivery.

Problems Solved

• The techniques solve the problem of efficiently switching between different delivery types (point-to-point and point-to-multipoint) for broadcast and multicast services.
• They ensure service continuity during the switching process, allowing uninterrupted reception of the service by the wireless device.

Benefits

• The techniques provide flexibility in delivering broadcast and multicast services, allowing for efficient use of network resources.
• They enable seamless switching between different delivery types without interrupting the service for the wireless device.
• The technology improves the overall user experience by ensuring uninterrupted reception of broadcast and multicast services.

Original Abstract Submitted

This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.
