Abstract: A method, apparatus, and computer program product for detecting and switching between locally available PLMNs accessible to a user equipment based on a Preferred PLMN List and a Network Slice Aware PLMN Exceptions List configured by a HPLMN. The user equipment connects to a preferred VPLMN. The user equipment determines that a particular network function is not supported by the connected preferred VPLMN. The user equipment determines that another VPLMN is required to support the particular network function. The user equipment then switches to a non-preferred VPLMN which supports the particular network function. Once the particular network function is no longer necessary for the user equipment to perform a required task, the user equipment switches back a preferred VPLMN

Abstract: A method, apparatus and computer program product are provided herein to provide a Protocol Data Unit (PDU) session priority parameter. For example, a method is provided that comprises identifying a need in a user equipment (UE) for establishing a new protocol data unit PDU session. The method also includes evaluating whether to establish a new PDU session and determining whether to establish a new PDU session based on a PDU session priority parameter when a maximum number of PDU sessions the UE can establish in the network is reached.

Abstract: A method, apparatus, and computer program product provide for adaptive paging for user equipment (UE) with multiple subscriber identification modules (SIMs). A UE may provide, in a registration message to the network, an indication that the UE supports multiple SIMs. The network may allow repeated paging to let a SIM miss a paging occasion without interpreting that the UE is unavailable. The indication from the UE can specify the number of SIMS supported by the UE. The network can adapt the number of paging repetitions to the UE. If the UE is accepting paging from another network or has a SIM that is already active with the network, the UE sends the network a paging control message. If the UE detects a paging occasion conflict, the UE sends the network a registration message with a replacement ID for paging another SIM, and the UE and the network negotiate appropriate paging.

Abstract: Methods and apparatus, including computer program products, are provided for UE capability signaling. An apparatus is provided that is caused to at least: receive, from a user equipment capability management function, a message including a first restart counter value indicating a restart of the user equipment capability management function; inhibit, in response to receiving the first restart counter value, one or more old user equipment capability identifiers associated with a second restart counter value, the second restart counter value being associated to a pre-restart state of the user equipment capability management function; and send the first restart counter value indicating the restart of the user equipment capability management function. Related systems, methods, and articles of manufacture are also described.

Abstract: Techniques for controlling the behavior of a user device toward a cell in a sliced network are provided. For example, a method of controlling a user device is disclosed. The method comprises: receiving, by the user device, a configuration message from a network node, the configuration message indicating whether to perform a cell reselection procedure and/or a random-access procedure taking into account priority of one or more network slice groups; and performing, by the user device, the cell reselection procedure and/or the random-access procedure taking into account priority of one or more network slice groups in accordance with the configuration message.

Abstract: There is provided an apparatus for use in a user equipment, wherein the user equipment is operable to be registered in a registration area, the apparatus comprising means configured to perform: providing, to a first network entity, a first message, wherein the first message comprises an indication that the user equipment supports non-uniformly supported network slices in the registration area. The means further configured to perform receiving, from a second network entity, a second message, wherein the second message comprises group mapping information for a tracking area of the registration area, wherein the group mapping information maps the tracking area to at least one group, the at least one group comprising a list of network slices that are non-uniformly supported in the tracking area.

Abstract: Systems, methods, apparatuses, and computer program products for efficient registration for partially supported service areas are provided. One method may include providing, to at least one user equipment registered to a network within a registration area, information comprising one or more single network slice selection assistance information (S-NSSAIs) and one or more tracking area identities (TAIs). Each of the one or more single network slice selection assistance information (S-NSSAIs) is included in a list of rejected single network slice selection assistance information (S-NSSAIs) or in a list of extended rejected single network slice selection assistance information (S-NSSAIs), and is associated with a cause value indicating that the single network slice selection assistance information (S-NSSAIs) is not supported uniformly in the registration area and is not supported in a current tracking area.
