Systems and methods for establishing shared n3 tunnel

A non-transitory computer readable storage medium storing instructions, which when executed by one or more processors can cause the one or more processors to:

• establish, at a first one of a plurality of wireless communication nodes, a tunnel based on at least one of:
• (i) whether a context of a Multicast and Broadcast Services (MBS) session is received;
• or (ii) one or more acknowledgement (ACK) messages corresponding to the context and the tunnel are received, the tunnel being shared by the plurality of wireless communication nodes for accessing a core network;
• wherein the plurality of wireless communication nodes share a same Centralized Unit-User Plane (CU-UP).

A wireless communication node, comprising:

• at least one processor configured to:
• establish a tunnel based on at least one of:
• (i) whether a context of a Multicast and Broadcast Services (MBS) session is received;
• or (ii) one or more acknowledgement (ACK) messages corresponding to the context and the tunnel are received, the tunnel being shared by a plurality of wireless communication nodes for accessing a core network;
• wherein the plurality of wireless communication nodes share a same Centralized Unit-User Plane (CU-UP), and includes the wireless communication node.
