A system described herein may provide a technique for a policy and/or rules element of a core network, such as a Policy Control Function ('PCF'), to identify a first network slice with which a communication session between a User Equipment (“UE”) and a core network, such as a protocol data unit (“PDU”) session, is associated. The policy and/or rules element may identify a second network slice with which the communication session should be associated, such as based on traffic monitoring, network congestion monitoring, or other criteria, and may output an indication, indicating a second network slice, to a session control element, such as an Session Management Function (“SMF”). The session control element may cause the communication session to be moved from the first network slice to the second network slice based on receiving the indication.

Systems and methods for network slice modification by policy control function in a wireless network

A device may receive data indicating a required quality of service (QoS), and may receive radio access network (RAN) information associated with a RAN, wherein the RAN information is provided by a centralized unit (CU) of the RAN. The device may provide the RAN information to a multi-access edge computing (MEC) platform, and may receive, from the MEC platform, a QoS request that requests the required QoS. The device may provide the QoS request to the CU, and may receive a QoS response to the QoS request. The device may provide the QoS response to a policy control function (PCF) of a core network, and may receive an indication of approval of the QoS response from the PCF. The device may cause, based on receiving the indication of approval, the required QoS to be implemented by the MEC platform and network devices associated with the core network.

Systems and methods for providing edge-based quality of service orchestration for multi-access edge computing (MEC) in a network

A method, a device, and a non-transitory storage medium are described in which a edge network exposure function service is provided. An edge network exposure function device may provide the edge network exposure function service. The edge network exposure function service may communicate with a radio access network, a mobile edge computing network, and a main edge network exposure function device to provide radio access network, end device, and control information. The edge network exposure function device may also facilitate handovers of an end device between mobile edge computing networks. The edge network exposure function device may be situated at the network edge and the main network exposure function device may be situated in a core network.

Method and system for edge network exposure function with MEC network

A system may receive a request from the UE device to establish a session over a user plane of a network; establish a session over the user plane in response to the request from the UE device; receive, at a first node, uplink IP data from the UE device over the session; redirect the received IP data at the first node to a second node for translating IP data to a T8 message; translate, at the second node, the redirected IP data to a first T8 message; and forward the first T8 message to an application server or an application function (AF) node.

System and method for using T8 API to deliver data over an IP path

A device may receive, from a network device, a user equipment (UE) parameter update request notification indicating an update to a UE parameter of a universal subscriber identity module (USIM), and may generate an encrypted UE parameter update request. The device may cause the encrypted UE parameter update request to be provided to the USIM to cause the USIM to update the UE parameter and to generate an encrypted UE parameter update response. The device may receive, from the network device, the encrypted UE parameter update response, and may verify an authenticity of content of the encrypted UE parameter update response based on whether the encrypted UE parameter update response is signed by the USIM. The device may provide, to the network device, a result indicating whether the UE parameter is updated and whether the authenticity of the content of the encrypted UE parameter update response is verified.

Systems and methods for securely updating and managing universal subscriber identity module information

Systems and methods described herein provide stateless network functions for a wireless core network. A network device in the wireless core network receives, from a network function instance in a set of network function instances, context information and state maintenance parameters for an end device. The state maintenance parameters include one or more timer values for the end device, and an action to be performed upon expiry of the one or more timer values. The network device stores the context information and the state maintenance parameters, and applies the state maintenance parameters to the context information for the end device. The network device performs the action when expiry of the one or more timer values is detected.

Method and system for stateless network function services in 5G networks

An example method can include receiving, by a device, single-network slice selection assistance information (S-NSSAI) associated with a user equipment. The S-NSSAI can be associated with a network. The method can include determining location information associated with the user equipment, determining that a network slice instance (NSI) is to be created for the S-NSSAI, and creating an NSI based on a network service (NS) associated with the user equipment. The NSI can be created using a network function virtualization orchestrator (NFVO), associated with the network, that allocates resources, of the network, for the NSI according to the NS.

Network slice instance creation

A system in wireless core network obtains a group policy to support background data transfer for a group of user equipment (UEs) associated with a common network area identifier. The system maps the network area identifier to one or more of a mobility management entity (MME) device and a packet data network gateway (PGW) device. The system generates a configuration command to enforce the group policy by the one or more of the MME device or the PGW device and configures, based on the configuration command, the one or more of the MME device or the PGW device to enforce the group policy.

System and method for enforcing group policies for MTC devices to perform background data transfers

A first network device determines a first pointer value associated with a first management instance that includes at least one of network access or mobility management functions for user equipment (UE) interaction with a wireless network. The first network device installs, at a second network device, the first management instance, along with the first pointer value. The first network device changes the first pointer value in response to a first event associated with the wireless network or one or more other networks. The first pointer value is used for selecting at least one management instance, among a plurality of management instances that include the first management instance, for servicing wireless service requests from UEs to the wireless network.

Mobility management node selection to support cloud-centric environments

A first network device determines a set ID associated with a first set of management instances in at least one network, wherein the management instances execute network access or mobility management functions for UE interaction with a wireless network and wherein a first management instance is a member of the first set of management instances. The first network device determines a first pointer value associated with the first management node, generates a first global ID, for the first management instance, that includes the set ID and the first pointer value, and installs the first management instance at a second network device, along with the first global ID, the set ID, and the first pointer value. The first network device changes the first pointer value in response to an event, wherein the event is associated with planned maintenance, a planned upgrade, or an existing or predicted outage of the wireless network.

A method, a device, and a non-transitory storage medium having instructions to store data that provides mappings between criteria information and lists of codecs; receive an indication that one of an audio session, a video session, or an audio and video session is to be initiated with another device; obtain one or more criteria metric values in response to a receipt of the indication; select one of the lists of codecs from the data based on one of the mappings and the one or more criteria metric values; transmit the one of the lists of codecs to the other device via a wireless network; receive a response, via the wireless network, from the other device, wherein the response indicates one of the codecs; and use the one of the codecs during the one of the audio session, the video session, or the audio and video session.
