Abstract: There is provided a method at a first network node, comprising: receiving, from a second network node, a message comprising a requested quality of service (QoS) profile and one or more alternative QoS profiles, wherein the QoS profiles are associated with a communication with a user equipment; determining that the requested QoS profile cannot be provided by the first network node for a communication between the first network node and the user equipment; determining that at least one of the one or more alternative QoS profiles can be provided by the first network node for a communication between the first network node and the user equipment; transmitting, to the second network node, an indication that an alternative QoS profile can be provided by the first network node; and, transmitting, to the second network node, an indication for configuring the user equipment based on the requested QoS profile.

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.

Abstract: Systems, methods, apparatuses, and computer program products for multicast-broadcast service (MBS) deactivation and/or activation are provided. One method may include receiving, at a multicast-broadcast session management entity, a multicast-broadcast service (MBS) session setup message, from at least one management entity, comprising at least one of an identifier of at least one network node requesting setup of the multicast-broadcast service (MBS) session and an identifier of the at least one management entity. The method may also include storing, at the multicast-broadcast management entity, at least one of the identifier of the at least one network node, the identifier of the at least one management entity, or an identifier of a region of the at least one management entity.

Abstract: A system, apparatus, method, and non-transitory computer readable medium for reducing and/or optimizing signaling messages between a radio access network (RAN) node and a core network based on an operation mode of the RAN node may include a core network server including: a memory storing computer readable instructions; and at least one processor configured to execute the computer readable instructions to establish a control plane connection with at least one radio access network (RAN) node, the at least one RAN node supporting at least a first connection mode and a second connection mode, determine a connection mode of the at least one RAN node, and restrict transmission of at least one signaling message to the at least one RAN node based on results of the determining the connection mode of the at least one RAN node.
