Title:
MULTICAST/BROADCAST COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/241691
Kind Code:
A1
Abstract:
The present application provides a multicast/broadcast communication method and apparatus. The method comprises: a first multicast/broadcast session management function network element receives information of a first playback area, the first playback area being a service area of a first multicast/broadcast service managed by the first multicast/broadcast session management function network element; and the first multicast/broadcast session management function network element creates a transmission tunnel between a first user plane function network element and a second user plane function network element by means of a second multicast/broadcast session management function network element, wherein a service area of the second multicast/broadcast session management function network element comprises a first area, the first area belongs to the first playback area but does not belong to the service area of the first multicast/broadcast session management function network element, the first user plane function network element is managed by the first multicast/broadcast session management function network element, and the second user plane function network element is managed by the second multicast/broadcast session management function network element. In embodiments of the present application, the first multicast/broadcast session management function network element creates the transmission tunnel, so that a base station beyond the service area range of the first multicast/broadcast session management function network element can indirectly receive data of the first multicast/broadcast service, thereby improving the reliability of data transmission.
