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: Systems, methods, apparatuses, and computer program products for conditional handover (CHO) execution with network slice service continuity prioritization are provided. A radio resource control (RRC) reconfiguration message sent by a source radio access network (RAN) node to the user equipment (UE) may include, for each CHO configuration, an associated network slice-related priority index. The UE may take this index into account when selecting a suitable cell during CHO recovery. Additionally, or alternatively, the RRC reconfiguration message sent by a source RAN node may include, for each CHO configuration, an associated network slice support information of the candidate target cell. The message may also include network slice remapping information for any network slice associated with one of the candidate target cells. Using the above network slice-related information received from the network, the UE can prioritize the cell to select during CHO recovery in case more than one suitable cell is available.

Abstract: An apparatus and method are provided for sending a first data packet comprising a Quality of Service (QoS) data flow identifier indicating a QoS data flow which the first data packet belongs to, and a data flow sequence number indicating a position of the first data packet in a sequence of the QoS data flow. A second data packet that is a duplicative of the first data packet is sent in a second QoS data flow, and has a sequence number that is incremented from that of the first data packet. The duplicative packets are transmitted via a first tunnel for transmitting the first QoS flow and a second tunnel for transmitting the second QoS flow. Reliability of such data transmission may therefore be improved. The duplication and sequencing may be implemented in the downlink and/or uplink direction.
