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 network device executes an account management function that pre-authorizes network service unit consumption by multiple subscribers that are members of a same, shared network service account. The account management function receives, from multiple charging systems distributed within the network, network unit consumption charges associated with each of the multiple subscribers, where the network device is centrally located within a network relative to multiple locations associated with the plurality of charging systems. The account management function updates a consumption counter for the same, shared network service account based on the network unit consumption charges associated with the multiple subscribers received from the multiple charging systems distributed within the network.

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 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： Systems and methods described herein allow mobile network operators to provide an adaptive quality of service (QoS) approach for application providers. A network device in a core network receives a QoS monitoring report based on QoS monitoring by an access station. The QoS monitoring report includes data for QoS parameters for network services in a default QoS flow supporting a protocol data unit (PDU) session. Based on the QoS monitoring report, the network device determines if the default QoS flow supports a required service level for the PDU session. When the network device determines that the default QoS flow does not support the required service level for the PDU session, the network device automatically activates a dedicated QoS flow to support the PDU session with the required service level.

摘要： A network device receives an attach request indicating that a user device is attempting a connection associated with a non-access stratum (NAS) and a particular interface, and generates a create session request that includes an indication that the connection for the user device is associated with the NAS and the particular interface. The network device provides, to a serving gateway (SGW) of the network, the create session request that includes the indication, and receives, from the SGW, a create session response that includes rules for handling the connection for the user device that is associated with the NAS and the particular interface, wherein the rules have been generated by a policy and charging rules function (PCRF) of the network. The network device provides, to the user device, an attach accept, that includes the rules, to permit the user device is to connect with the network and to utilize the rules.

摘要： A system described herein may provide a technique for an inter-segment Network Function (“NF”) discovery procedure in a network that includes multiple discrete network segments. The network segments may each include a respective set of NFs. An NF discovery request may include discovery parameters such as an identifier of a User Equipment (“UE”). Network segments may be checked in a sequential or hierarchical manner to determine whether a respective network segment includes an instance of the requested NF that matches the discovery parameters (e.g., is associated with the UE identified in the NF discovery request).

摘要： Disclosed are systems and methods for intelligent, real-time network consumption tracking and traffic steering in fifth-generation (5G) networks via a network configuration and implementation. The disclosed hybrid network traffic steering is effectuated by using Diameter Routing Agent (DRA) and Subscriber Location Function (SLF) to route/steer fourth-generation (4G) network traffic by 5G subscribers to a 5G Charging Function (CHF) for 4G fallback network consumptions. Network currency consumption tracking is performed by the 5G CHF. The CHF dictates policy rules for 5G networks via the Policy Control Function (PCF) of the 5G Core, and dictates policy rules for 4G networks via the Policy and Charging Rules Functions (PCRF) for fallback sessions.

摘要： A device connected to a wireless network receives, from a mobile user equipment device (UE) associated with a user, a wireless network service request. The device obtains the user's subscribed mobility handover techniques, where the user's subscribed mobility handover techniques include one or more mobility handover techniques selected by the user from multiple different mobility handover techniques associated with at least one wireless network service plan. The device executes the one or more different mobility handover techniques selected by the user for maintaining wireless communication with the mobile UE as the mobile UE moves within the wireless network.
