1. A control plane network entity for providing a multicast/broadcast service for one or more user equipments in a cellular communication network, wherein the cellular communication network comprises a core network (CN) and a radio access network (RAN), and is configured to provide a control plane (CP) and a user plane (UP), wherein the control plane network entity comprises a memory and a processor coupled to the memory, wherein the memory stores a program code, and when the program code is executed by the processor, the control plane network entity is configured to:
receive a session setup request for a multicast/broadcast session for the one or more user equipments from an application server (AS) of the cellular communication network,
wherein the control plane network entity is selected by the AS using a network repository function (NRF);
wherein the session setup request comprises one or more identifiers identifying the one or more user equipments, and one or more spatial regions in which the one or more user equipments are located;
select one or more access and mobility management function entities of the cellular communication network on the basis of the one or more identifiers, for providing the multicast/broadcast session to the one or more user equipments;
send a user plane session setup request to the selected one or more access and mobility management function entities; and
send a user plane session configuration request to a user plane function (UPF) of the cellular communication network in response to receiving a user plane session setup confirmation from the selected one or more access and mobility management function entities, and
wherein the user plane session configuration request comprises one or more session attributes, based on which the UPF is configured to establish a user plane between the CN and a RAN node of the RAN, wherein the one or more session attributes comprise the one or more spatial regions in which the one or more user equipments are located and one or more identifiers identifying the one or more user equipments, and
wherein the RAN node anchors the multicast/broadcast session for the one or more user equipments.
