1. An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program instructions, which, when executed by
the at least one processor, cause the apparatus at least to perform:
detecting a restart of a multicast/broadcast user plane function that was supporting a packet forwarding control protocol session for a multicast/broadcast session; and
re-creating, based on the detecting, a packet forwarding control protocol session for the multicast/broadcast session, the re-creating comprising:
providing addressing information, used prior to the restart of the multicast/broadcast user plane function for the delivery of data of the multicast/broadcast session to the multicast/broadcast user plane function and instructing the multicast/broadcast user plane function to use the addressing information for the multicast/broadcast session, wherein the addressing information is provided by the multicast/broadcast session before the restart of the multicast/broadcast user plane function.
