Abstract: An apparatus includes, in some embodiments, at least one processor and at least one memory storing instructions which, when executed by the at least on processor, causes the apparatus at least to receive a multicast service area update request comprising information defining a change in multicast service area for a multicast service session. A user equipment affected by the changed multicast service area is determined, as is a location of the user equipment affected by the changed multicast service area. It is determined whether the user equipment affected by the changed multicast service area is within the changed multicast service area. A protocol data unit session of the user equipment affected by the changed multicast service area is modified with information about the changed multicast service area, based on determining whether the user equipment affected by the changed multicast service area is within the changed multicast service area.

Abstract: Techniques for determining a registration area are provided. A network entity may receive one or more indications of topology information from one or more radio access network nodes. Each indication of topology information is related to one or more tracking areas and each tracking area is associated with one or more cells in a radio access network served by each of the one or more radio access network nodes. The network entity may determine a registration area based at least in part on the received one or more indications of topology information related to the one or more tracking areas.

Abstract: Systems, methods, apparatuses, and computer program products for determining random access channel (RACH) resources or parameters based on network slice-based resource allocation classes (RACs) may be provided. A mapping between network slices and a set of RACs may be determined by a core network (CN). The CN may send this mapping to the UE. The UE may select RACH resources or parameters for a network slice. The radio access network (RAN) may determine a mapping between the RACs and the RACH resources or parameters. The UE may determine the corresponding RACH resources or parameters to be used for a RAC.

Abstract: Systems, methods, apparatuses, and computer program products for data transmission with stateless routing are provided. Certain embodiments may include a radio resource control (RRC)-less or RRC-based mechanism for short data transmission (SDT) in an RRC inactive state, where the mechanism may be performed without storing or establishing a UE context in a distributed unit (DU), for a UE served by a single CU-user plane (UP). Certain embodiments may include a RRC-less mechanism for SDT in an RRC inactive state, where the authentication of the user equipment (UE) may be performed at the UP using UP integrity protection (IP) in a CU-UP. Certain embodiments may include a RRC-based mechanism for SDT in an RRC inactive state, where the authentication of the UE may be performed at the UP using UP IP in a CU-UP and/or at the CP using CP IP in a CU-CP.

Abstract: According to certain embodiments, a method and apparatus may include performing, by a first network entity, at least one benchmarking procedure of at least one network hop delay per at least one transmit resource towards at least one peer network node identified by at least one internet protocol destination address. The method and apparatus may further include deriving, by the first network entity, a second table, by, for each peer node associated with an internet protocol destination address, determining at least one existing configured mapping of at least one network instance into a transport resource Ti per internet protocol destination address. The method and apparatus may further include updating, by the first network entity, the first table and the second table for each internet protocol destination address and transmitting the updated second table to the second network entity.

Abstract: According to an example embodiment, a network device is configured to:
generate an indicator based on at least one of an activation status of a multicast session or a data inactivity status; and transmit the indicator to a client device, wherein the indicator indicates to the client device whether the client device should wait for a paging message for the multicast session and stop monitoring data of the multicast session while the client device is in an inactive state.

Abstract: Methods, devices, apparatuses, and computer readable medium for enhancements on service continuity. The method includes receiving, at a source network node and from a user equipment, UE, being served by the source network node for a service associated with a network slice, a message indicative of a target network node for a handover of the UE from the source network node to the target network node; transmitting a handover request to the target network node, the handover request indicating urgency of the handover for the UE, and the target network node being overloaded for the network slice; and receiving a handover request acknowledgement message from the target network node, the handover request acknowledgement message indicating if multi-carrier radio resource sharing is applicable for supporting the service.

Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include receiving, by a user equipment attached to a public land mobile network as an inbound roamer, a service announcement for a broadcast session or service class indicating whether inbound roamers are allowed to access the broadcast service or service class; determining, based on the service announcement, whether the user equipment is allowed to access a broadcast session or service class in the public land mobile network; and in response to determining that the user equipment is allowed to access a broadcast session or service class in the public land mobile network, transmitting, by the user equipment, a multicast/broadcast service interest indication associated with the broadcast session or service class upon completion of a radio resource request.
