摘要： A network device may include a memory storing instructions and processor configured to execute the instructions to receive a request for a session management (SM) policy association in relation to establishment of a packet data unit (PDU) session for a particular user equipment (UE) device; sending, to a second network device, a request for an access and mobility (AM) policy decision pertaining to the UE device; receiving the AM policy decision from the second network device, and creating the SM policy association based on at least the received AM policy decision. The request for SM policy association includes an identifier associated with the second network device. The processor may be further configured to determine whether the network device is the same as another network device based on the identifier; and transmit a request to the second network device when it is determined that the first network device is not the same as the other network device.

摘要： A network device may receive an indication of movement of a user device, associated with multiple packet data unit (PDU) sessions, from a first radio access network (RAN) to a second RAN, and may maintain, based on the indication, a particular PDU session, of the multiple PDU sessions, associated with a default flow. The network device may release, based on the indication, the multiple PDU sessions other than the particular PDU session, and may handle the multiple PDU sessions, other than the particular PDU session, in accordance with a handling option.

摘要： A system comprises one or more devices. The devices may be configured to: receive information pertaining to a multicast broadcast service (MBS) session; identify, based on the information, User Equipment devices (UEs) that have joined the MBS session; identify at least two modulation schemes that are to be used by the UEs during the MBS session; receive multicast data from a network component; transmit, during the MBS session, the received multicast data to the UEs using the identified at least two modulation schemes.

摘要： A method, a device, and a non-transitory storage medium provide for provisioning network resources of multi-access edge computing (MEC) networks in support of an application service session for an end device; assigning an IP address to the end device for use in a first coverage area served by a first MEC network of the MEC networks; receiving, by a first application function (AF) device at the first MEC network, a session mobility notification for the end device with respect to the first coverage area and a second coverage area served by a second MEC network of the MEC networks; setting, responsive to the session mobility notification, an allotted time for relocating the application service session from the first MEC network to the second MEC network; and transferring, during the allotted time, application context corresponding to the relocated application service session to a second AF device at the second MEC network.

摘要： A method, a device, and a non-transitory storage medium are described in which an application-based access control service is provided. The service assigns network slice priority values to network slices that are associated with an application or a portion of an application pertaining to end devices. The service calculates a network slice priority value to manage access barring based on a congestion level, and transmits the network slice priority value to end devices. End devices may determine whether access is permitted or not based on the network slice priority value and the assigned network slice priority values associated with the network slices. The service further provides access barring information to network devices of an access network that allows the network devices to reject connection requests and release existing connections. The access barring information may include a network slice priority value and/or network slice identifiers.

摘要： Systems and methods described herein use group segmentation of applications (referred to herein as “slicing classes”), based on common service requirements, to allow carriers to assign UE traffic to network slices. A UE stores slicing class definitions for use with UE Route Selection Policies (URSP). Each of the slicing class definitions include network quality of service (QoS) characteristics that are applicable to network traffic for multiple software applications. The UE maps the software applications to corresponding slicing class identifiers associated with the slicing class definitions. The UE also stores URSP rules for associating a slicing class identifier with a network slice identifier. A UE operating system sends, to a modem, one of the slicing class identifiers for an application that is requesting attachment to a wireless network. The modem sends a registration request with a selected network slice identifier based on the received slicing class identifier and the URSP rules.

摘要： A method may include receiving, at a network device, a registration request that comprises a subscription concealed identifier (SUCI) associated with a particular user equipment (UE) device. The network device determines whether the SUCI indicates a request for null-scheme network access; and retrieves a scheme authorization parameter for the UE device when it is determined that the SUCI indicates a request for null-scheme network access. The scheme authorization parameter indicates whether the UE device is authorized for null-scheme access to a service provider network. The network device determines whether the UE device is authorized for null-scheme network access based on the retrieved scheme authorization parameter and performs processing associated with null-scheme network access when it is determined that the particular UE device is authorized for null-scheme network access.

摘要： Systems and methods provide reliable voice connections dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts a parameter barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.

摘要： A device may include a processor configured to determine that Quality of Service (QoS) monitoring is to be performed for a communication session; generate a QoS monitoring policy for the communication session; and provide the QoS monitoring policy to a Session Management Function (SMF) associated with the communication session. The processor may be further configured to receive a QoS monitoring report for the communication session from the SMF and perform an action based on the received QoS monitoring report.

摘要： A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an propagation delay compensation service. The propagation delay compensation service may calculate or select propagation delay compensation method and configuration data based on a time synchronization error budget value, which may be calculated based on quality of service information associated with a network slice, network slice information, and time sensitive communication assistance information. The propagation delay compensation service may calculate or select the propagation delay compensation method and configuration data based on other context information.
