Abstract: Devices, methods and computer programs for small data trans-Client device Control Plane whether an ongoing small data transmission, SDT, transaction comprising one or more uplink, UL, small data transmissions with a control plane network node device is to be terminated. If yes, a radio resource control, RRC, message comprising termination information related to the determined termination of the on-ongoing SDT going SDT transaction is forwarded from the client device to the control plane terminated network node device.

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.

Abstract: Systems, methods, apparatuses, and computer program products for broadcast service restoration for multicast/broadcast service upon radio access node failure or restart are provided. For example, a method may include storing a last multicast/broadcast service session information received from a multicast/broadcast session management function corresponding to a multicast/broadcast service session. The method may also include detecting that a radio access node associated with the multicast/broadcast service session has restarted or is unreachable. The method may further include taking a further action to adjust the delivery of the multicast/broadcast service session based on the detection.

Abstract: Systems, methods, apparatuses, and computer program products for configured grant small data transmission reconfiguration without user equipment context in a distributed unit are provided. For example, a method can include receiving, at a first network element, data in a transmission from a user equipment. The method can also include storing a first indication of a first configuration used by the user equipment to perform the transmission. The method can further include sending, to a second network element, a resume request to set up communication context for the data transmission. The method can additionally include receiving, from the second network element, a second indication of a second configuration previously allocated to the user equipment. The method can also include comparing the first indication and the second indication. The method can further include proceeding with setting up the communication of the data based on the comparing.
