Abstract
There is provided an apparatus, said apparatus comprising, at a multicast/broadcast session management function of a core network, means for receiving information related to a shared centralised unit user plane, CU UP for a multicast/broadcast session, from a radio access network, RAN, node or an access management function of the core network, means for determining, based on the information, whether to configure a user plane function of the core network to deliver data or to terminate delivery of data for the multicast/broadcast session towards the shared CU UP and means for, if so, configuring the user plane function to deliver data or to terminate delivery of data for the multicast/broadcast session towards the shared CU UP.
Claims18
An apparatus comprising:
- at least one processor and at least one memory including a computer program code, the at least one memory storing computer program code of a multicast/broadcast session management function for a core network, the computer program code, when executed by the at least one processor, causing the apparatus at least to perform operations, the operations comprising:
- receiving information related to a shared centralised unit user plane, shared CU UP, for a multicast/broadcast session, from a radio access network, RAN, node or an access management function of the core network, wherein the information comprises an identity associated with the RAN node and an indication that indicates whether delivery of data or termination of the delivery of data is requested;
- determining, based on the information, whether to configure a user plane function of the core network to deliver data or to terminate the delivery of data for the multicast/broadcast session towards the shared CU UP, wherein the determining comprises determining to configure, in an instance that no other RAN node previously requested the delivery of data for the multicast/broadcast session towards the shared CU UP and the indication indicates that the delivery of data is requested, the user plane function to deliver the data for the multicast/broadcast session towards the shared CU UP;
- and
- configuring, based on the determining, the user plane function to deliver the data or to terminate the delivery of data for the multicast/broadcast session towards the shared CU UP.
A method of a network node of a core network, the network node implementing a multicast/broadcast session management function, the method comprising:
- receiving information related to a shared centralised unit user plane, shared CU UP, for a multicast/broadcast session, from a radio access network, RAN, node or an access management function of the core network, wherein the information comprises an identity associated with the RAN node and an indication that indicates whether delivery of data or termination of the delivery of data is requested;
- determining, based on the information, whether to configure a user plane function of the core network to deliver data or to terminate the delivery of data for the multicast/broadcast session towards the shared CU UP, wherein the determining comprises determining to configure, in an instance that no other RAN node previously requested the delivery of data for the multicast/broadcast session towards the shared CU UP and the indication indicates that the delivery of data is requested, the user plane function to deliver the data for the multicast/broadcast session towards the shared CU UP;
- and
- configuring, based on the determining, the user plane function to deliver the data or to terminate the delivery of data for the multicast/broadcast session towards the shared CU UP.
A non-transitory computer readable storage medium storing program instructions of a multicast/broadcast session management function for a core network, which, when executed by an apparatus, cause the apparatus to perform at least the following operations, the operations comprising:
- receiving information related to a shared centralised unit user plane, shared CU UP, for a multicast/broadcast session, from a radio access network, RAN, node or an access management function of the core network, wherein the information comprises an identity associated with the RAN node and an indication that indicates whether delivery of data or termination of the delivery of data is requested;
- determining, based on the information, whether to configure a user plane function of the core network to deliver data or to terminate the delivery of data for the multicast/broadcast session towards the shared CU UP, wherein the determining comprises determining to configure, in an instance that no other RAN node previously requested the delivery of data for the multicast/broadcast session towards the shared CU UP and the indication indicates that the delivery of data is requested, the user plane function to deliver the data for the multicast/broadcast session towards the shared CU UP;
- and
- configuring, based on the determining, the user plane function to deliver the data or to terminate the delivery of data for the multicast/broadcast session towards the shared CU UP.
