Abstract: Embodiments described herein may provide for the return (e.g., reconnection) of a User Equipment (“UE”) to a first radio access network (“RAN”) to which the UE was connected, after the UE has been redirected to a second RAN based on the occurrence of an event. The event may include a voice call placed by or to the UE. The return of the UE to the first RAN may occur based on the occurrence of another event, such as the voice call being terminated.

Abstract: A system described herein may receive a request for a User Equipment (“UE”) to access a radio access network (“RAN”), which may implement a Closed Subscriber Group (“CSG”) technique. The request may be a handover request from a different RAN, which may implement a different radio access technology (“RAT”). The system may determine that an access policy for the particular RAN does not indicate that the UE is authorized to access the RAN. The system may output a request to the RAN, including an indication that the access policy for the RAN does not indicate that the UE is authorized to access the RAN. The system may receive a response to the second request. The response may include an indication of whether the UE is allowed to access the RAN, as determined by the RAN based on one or more conditions in addition to an identifier of the UE.

Abstract: A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an LAS service. The LAS service may include enablement or disablement of the LA service subsequent to an establishment and active traffic flow associated with an application session. The LAS service may be enabled or disabled based on performance metric criteria and threshold values not being satisfied or being satisfied. The LAS service may be implemented to include an exposure function.

Abstract: 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).

Abstract: A device may include a processor configured to maintain a plurality of session management entities (SMEs) for a core network associated with a radio access network (RAN). The processor may be further configured to establish a communication session using a first SME, of the plurality of SMEs; store session data for the communication session in a communication session database accessible by each of the plurality of SMEs; receive, using a second SME of the plurality of SMEs, a message associated with the communication session; retrieve, using the second SME, session data for the communication session from the communication session database, based on receiving the message; and process, using the second SME, the message using the retrieved session data.

Abstract: A device receives a call invitation message with a Session Description Protocol (SDP) offer for establishing a call between a calling party and a called party and obtains a set of network fallback rules associated with the called party. The device determines, based on the set of network fallback rules, whether to reject the call and avoid network fallback from a first wireless network to a second wireless network. The device sends, based on the determination, a call denial message without an SDP answer, to reject the call and avoid the network fallback.

Abstract: A network device receives a first message that includes an identifier (ID) of a first User Plane Function (UPF), serving a first device, in a wireless network, where the first message invites a second device to engage in a session with the first device and where the first UPF supports packet routing and forwarding within the wireless network. The network device extracts the ID of the first UPF from the first message and determines a closest media resource function (MRF) to the first UPF, where the MRF processes and routes media streams between devices. The network device assigns the determined MRF as an anchor, in a network path between the first device and the second device, for processing and routing of media streamed between the first device and the second device.

Abstract: A device may include a processor configured to determine, in a core network associated with a radio access network, that a user equipment (UE) device, associated with an enterprise, has attached to the core network via a base station in the radio access network. The processor may be further configured to obtain a mapping between a plurality of applications associated with the enterprise and a plurality of Quality of Service (QoS) classes; identify an application, of the plurality of applications, for a communication session associated with the UE device; select a QoS class, from the plurality of QoS classes based on the identified application and the obtained mapping; and process messages associated with the communication session based on the selected QoS class.
