Abstract
Methods, apparatus, and systems that establish Multicast and Broadcast Service sessions based on existing tunnels between the core network and radio access nodes are disclosed. In one example aspect, a wireless communication method includes receiving, by a first communication node, a request from a core network node to establish a session. The request comprises a list of tunnels established between the core network node and other communication nodes to provide multicast and broadcast service. The method includes selecting, by the first communication node, a channel from the list of tunnels included in the request to establish a multicast and broadcast session that corresponds to the session. The method also includes transmitting, by the first communication node to the core network node, a response indicating an establishment of the session. The response includes information associated with the selected channel between the second communication node and the core network node.
