Abstract: An apparatus and a method for reallocation of global unique temporary identifier (GUTI) in 5G networks are disclosed. The method includes receiving, at a user equipment, a first message from a network, the first message including a first global unique temporary identifier and additional information, at least the first global unique temporary identifier being as-signed to the user equipment; receiving a first data transmission including the first global unique temporary identifier from the network; in response to receiving the first data transmission, deriving, at the user equipment, a second global unique temporary identifier based on the first global unique temporary identifier and the additional information; and receiving a second data transmission including the second global unique temporary identifier from the network.

Abstract: There is provided reduced power consumption in devices that use at least two identities for communications. A method comprises aligning (1302) a plurality of paging occasions across at least two identities of a communication device. The aligning is performed via requesting and receiving (1306) from a communication network a paging occasion for the communication device with at least two identities using at least one of the identities.

Abstract: Techniques for facilitating onboarding to a non-public network is provided. Provisioning parameters may be provided to User Equipment (UE) from a Default Credential Server (DCS) via a secure communication tunnel. Additionally or alternatively, provisioning parameter container(s) including readable provisioning parameters for an Onboarding Network (ONN), and secure provisioning parameters for the UE, may be transmitted to the UE via the ONN. The disclosed methods and apparatuses enable the UE to onboard to a non-public network using the provisioning parameters, and to verify the integrity of the provisioning parameters and ensure the provisioning parameters are not modified by an unauthorized device.

Abstract: Systems, methods, apparatuses, and computer program products for dynamically updating routing identifiers (IDs) are provided. One method may include deciding, at a network node, to update a routing identifier for at least one user equipment. The method may then include obtaining or generating a new routing identifier to be assigned to the at least one user equipment along with authentication vectors, and transmitting the new routing identifier to an authentication entity.

Abstract: Various communication systems may benefit from handling of various connection states. For example, certain wireless communication systems may benefit from a hybrid release that may enable any access management function to process a user equipment transaction. A method can include determining, by an access management function, whether to remain a serving node for a user equipment. The method can include taking an action with respect to an NG2 association for the user equipment based on the determination.

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: In some example embodiments, there may be provided a method that includes receiving, at a user equipment while being served by a first system and during protocol data unit session establishment or modification procedure, a message including an access point name aggregate maximum bit rate value; and when there is an inter-system change from the first system to the second system, setting, at the user equipment, the access point name aggregate maximum bit rate value of a session management context for the second system to the received access point name aggregate maximum bit rate value received while being served by the first system. Related systems, methods, and articles of manufacture are also described.

Abstract: A method, apparatus and computer program product are provided herein to receive, from a source, performance requirements, and cause transmission, to a network, of a request to influence time sensitive communications (TSC) configuration parameters. For example, a method is provided to in response to the request to influence TSC configuration, receive, from the network, network configuration and radio access network (RAN) resource constraints and determine a quality of service (QoS) and the TSC configuration parameters to support a TSC data stream based on the performance requirements received from the source, the network configuration, and the RAN resource constraints. The method is further configured to cause transmission of the determined QoS and the TSC configuration parameters to the network and the source and in an instance the network accepts the determined QoS and the TSC configuration parameters, configure resources for the TSC data stream and continuously support service continuity.
