Abstract
Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast user plane function failure without restart are provided. For example, a method may include detecting non-functionality of a first multicast/broadcast user plane function that was supporting a packet forwarding control protocol session context for a multicast/broadcast session. The method may also include reselecting a second multicast/broadcast user plane function. The method may further include recreating a packet forwarding control protocol session context in the second multicast/broadcast user plane function for said multicast/broadcast session. The method may additionally include receiving new addressing information for the delivery of said multicast/broadcast session data from said second multicast/broadcast user plane function. The method may also include updating a network element with the new addressing information.
