Abstract: Method, apparatus and computer program product for slice aware pre-emption signaling. A method include receiving (500) at a network node, a first session setup or modification request message for a first user equipment setting up a first session flow. The method also includes receiving (505) at the network node, a second session setup or modification request message for a second user equipment setting up a second session flow. The method further includes receiving (510) at the network node, a third session setup or modification request message for a third user equipment setting up a third session flow. In addition, the method includes pre-empting (515) the first session flow or the second session flow based on a pre-emptable information element or a non-pre-emptable information element.

Abstract: Systems, methods, apparatuses, and computer program products for the configuration of user device(s) for reception of point-to-multipoint transmission are provided. One method may include receiving, at a user equipment, a configuration for point-to-multipoint reception of a group-common transport channel. The configuration may include a group-common signaling configuration for a group of user equipment. The method may also include receiving, at the user equipment, a point-to-multipoint reconfiguration message using the group-common signaling configuration on the group-common transport channel from a device (e.g., a network node). The point-to-multipoint reconfiguration message may include an updated point-to-multipoint configuration. The method may then include receiving point-to-multipoint data, from the device on the group-common transport channel, based on the updated point-to-multipoint configuration.

Abstract: A method comprising transmitting a configuration of a default time period, wherein the default time period is for allowing a terminal device to consider a request for leaving an active network connection to a first network as accepted by the first network if the first network does not send a response within that the default period, to the terminal device, receiving a first message, from the terminal device, indicating a request to leave the active network connection, determining an overriding condition that overrides the default time period for leaving the active network condition and transmitting, to the terminal device, a second message comprising the overriding condition.

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.
