Abstract
Methods, apparatus, and systems for enabling effective reuse of a multicast or shared tunnel for a multicast and broadcast service are described. In one example aspect, a wireless communication method includes receiving, by a network node in a core network, information from a first access node requesting a multicast tunnel associated with a multicast and broadcast service, and transmitting, by the network node to the first access node, information about a shared tunnel associated with the multicast and broadcast service that has been established for a second access node.

A method of wireless communication, comprising:
- receiving, by a network node in a core network, information from a first access node in a first radio access network (RAN) requesting a multicast tunnel associated with a multicast and broadcast service;
- and
- transmitting, by the network node to the first access node, information about a shared tunnel associated with the multicast and broadcast service that has been established for a neighboring second access node in a second RAN,
- wherein the first access node and the neighboring second access node share a same user plane resource for the multicast and broadcast service, and
- wherein the shared tunnel established for the neighboring second access node is determined, by the first access node, to be usable by the first access node.
A method of wireless communication, comprising:
- transmitting, by a first access node in a first radio access network (RAN) to a network node in a core network, information requesting a multicast tunnel associated with a multicast and broadcast service;
- receiving, by the first access node, information about a shared tunnel associated with the multicast and broadcast service that has been established for a neighboring second access node in a second RAN, wherein the first access node and the neighboring second access node share a same user plane resource for the multicast and broadcast service;
- and
- transmitting, by the first access node to the network node, a response indicating that the shared tunnel established for the neighboring second access node is usable by the first access node for the multicast and broadcast service.
A method of wireless communication, comprising:
- transmitting, by a second access node in a second radio access network (RAN) to a network node in a core network, information requesting a shared tunnel associated with a multicast and broadcast service;
- receiving, by the second access node, an indicator from the network node indicating an establishment of the shared tunnel associated with the multicast and broadcast service for the second access node;
- and
- transmitting, by the second access node, information about the shared tunnel associated with the multicast and broadcast service to a neighboring first access node in a first RAN, wherein the neighboring first access node and the second access node share a same user plane resource for the multicast and broadcast service, and
- wherein the shared tunnel established for the second access node is determined, by the neighboring first access node, to be usable by the neighboring first access node.
