Abstract: Embodiments of the present disclosure relate to small data transmission (SDT). In the embodiments, a distributed unit (DU) of a network device determines that data for small data transmission (SDT), from a terminal device comprises data for at least one signaling radio bearer (SRB), without comprising data for a data radio bearer, DRB. The DU transmits, to a control plane (CP) of a central unit (CU) of the network device, an indication that the data for SDT is associated with the at least one SRB, and without being associated with a DRB. In this way, the SDT can be optimized.

Abstract: There are provided measures for enabling/realizing broadcast session establishment, particularly improved broadcast session establishment within a multicast/broadcast service. Such measures exemplarily comprise that an access management element or function in a mobile communication system issues, in response to a request of broadcast session establishment from a session management element or function, one or more requests of broadcast session establishment operation to one or more radio access elements or functions, issuing a response of broadcast session establishment to the session management element or function, and provides an indication of completion of broadcast session establishment operation at the radio access elements or functions to the session management element or function upon obtaining a response of broadcast session establishment operation from all of the radio access elements or functions.

Abstract: A method, apparatus, and computer program product provide for generating and providing a signaling indicator to manage quality of service notifications in a network. In the context of a method, the method receives a signaling indicator from a user device. The signaling indicator includes data associated with one or more preferences of the user device. The method further receives a quality of service notification associated with the user device. The method also determines, based on the signaling indicator, whether to provide the quality of service notification to the user device.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for NG based context release and data forwarding for multi-hop mobility. In an example implementation, the method may include a core network entity receiving a first message from a first network node, the first message including at least one of a user equipment context release request and a data forwarding request and detecting the at least one of the user equipment context release request and the data forwarding request from the first message. The method may further include sending a second message including at least one of a user equipment context release command and data forwarding information to a second network node based at least on the detected at least one of the user equipment context release request and the data forwarding request.

Abstract: A control plane function of a core network of a communication network system derives a parameter relating to transport resources for a user plane from an identification relating to logical network resources of a session, and provides the parameter to a user plane function of the core network and to a control plane control unit of an access network. The control plane control unit provides information derived from the parameter to a user plane control unit of the access network, and wherein the transport resources relate to a logical transport network to use to carry the user plane of the session. Based on the received information, the user plane control unit derives the transport resources to be used for the session over the user plane, and exchanges user plane traffic for the session over the derived transport resources.
