    Abstract: Embodiments of the present disclosure provide methods, apparatus and computer program products for providing broadcast/multicast services. A method at least partially implemented at an application server comprises transmitting a resource request message to a first broadcast/multicast control node (BM-CN), requesting an allocation of broadcast resource for delivering a multimedia broadcast/multicast service (MBMS) user service; transmitting a further resource request message to a second BM-CN, requesting a further allocation of broadcast resource for delivering the MBMS user service; receiving a first response message from the first BM-CN and a second response message from the second BM-CN, the first response message indicating a first broadcast resource allocated by the first BM-CN for the MBMS user service, and the second response message indicating a second broadcast resource allocated by the second BM-CN for the MBMS user service; and indicating information about the second broadcast resource to the first BM-CN and/or indicating information about the first broadcast resource to the second BM-CN. Methods at the BM-CN and a RAN network node, and corresponding apparatus are also provided.

    Abstract: A technique, comprising: receiving at a node of a radio access network of a mobile communication system one or more control plane messages indicating a plurality of quality-of-service profiles for a quality-of-service flow for a logical connection between a user equipment and a data network via the radio access network; receiving user plane messages for the quality-of-service flow at the radio access network node, wherein an individual user plane message comprises a header comprising at least a first field; determining at the radio access network node one of the plurality of quality-of-service profiles to adopt for the quality-of-service flow based on the first field and an indication in the one or more control plane messages of a mapping of the plurality of quality-of service profiles to a plurality of values for the first field.

    Abstract: Systems, methods, apparatuses, and computer program products for simultaneous registration to multiple networks are provided. A user equipment (UE) may perform dual registration to multiple networks, e.g., a 5G system (5GS) of equivalent public land mobile networks (PLMNs), equivalent stand-alone non-public networks (SNPNs), or a combination of PLMNs and SNPNs. When a UE is registered to the first network, the UE may select the second network for a second registration based on one or more criteria.

    Abstract: Techniques are provided for enabling user equipment (UE) context retrieval in radio resource control RRC inactive status with a shared radio access network (RAN) database (DB) within a distributed database architecture. A version indicator in an inactive Radio Network Temporary Identifier (I-RNTI) is populated by the UE to indicate one or more I-RNTI versions, defined herein, and indicates the type of data in the remainder of the I-RNTI used for communicating the location of a RAN DB that stores the UE context, to a target network node. The target network node then uses the data in the I-RNTI, further dependent on the I-RNTI version, to retrieve the UE content from the RAN database. Certain embodiments utilize a RAN DB Area (RDBA) and/or RAN DB Set Area (RDSA), and certain embodiments utilize a network node set ID.

    Abstract: Systems, methods, apparatuses, and computer program products for creation of a PCS connection between the remote user equipment (UE) and the relay UE. The remote UE may provide its identifier (e.g., a subscription concealed identifier (SUCI)) to the relay UE and the relay UE may forward this identifier to the network so that the network can authenticate the remote UE. The network may check the authorization of using the relay UE and/or for relaying the remote UE (e.g., both the remote UE and the relay UE may be checked for a configuration that permits the relaying). For the authentication and authorization, the access and mobility management function (AMF) associated with the relay UE may forward the messages between the remote UE and the authentication server function (AUSF) of the remote UE. In this way, certain embodiments described herein may address certain security issues related to relaying a remote UE.

    Abstract: Systems, methods, apparatuses, and computer program products for device-to-device (D2D) assisted 5G timing synchronization by enabling or disabling time compensation are provided. One method may include determining to initiate a procedure to determine whether to enable or disable propagation delay (PD) compensation for acquiring 5G system (5GS) timing with a sidelink (SL) group of user equipment. When it is determined to initiate the procedure, the method may include transmitting propagation delay (PD) information of the user equipment as a sidelink (SL) groupcast message over a sidelink (SL) control channel to at least one of the group of user equipment, receiving at least one of acknowledgement or nonacknowledgement from one or more of the group of user equipment, and determining whether to enable or disable the propagation delay (PD) compensation based on the received acknowledgement or nonacknowledgement from the group of user equipment.
