Abstract: A first network device may receive, from an application server, a first request for a dedicated bearer session for an application with a quality of service (QoS) and for a notification of an idle session for the application. The first network device may generate, based on the first request, a second request to be notified regarding expiration of an idle session timer for the application, and may provide the second request to a second network device. The first network device may receive, from the second network device and based on the second request, a notification of expiration of the idle session timer for the application, and may provide, to the application server, the notification of expiration of the idle session timer for the application.

Abstract: A network device of a network may receive a registration request from a user equipment, and may generate, based on the registration request, a request for a usage limit control associated with the user equipment. The network device may provide the request for the usage limit control to another network device of the network, and may receive, based on the request, the usage limit control from the other network device. The network device may determine a policy for the user equipment based on the usage limit control, and may cause the policy to be implemented for the user equipment.

Abstract: In some implementations, a network device may receive a subscription request to subscribe to receive notifications associated with context data related to a registered session associated with a user equipment (UE). The registered session may be associated with a reauthorization timer that is associated with triggering the network device to provide a request for reauthorization of the registered session. The network device may provide, based on an expiration of the reauthorization timer, the request for reauthorization of the registered session.

Abstract: A system described herein may provide an interface between a Centralized Unit (“CU”) and a Network Repository Function (“NRF”) of a wireless network. A first CU may receive, from the NRF, an indication that a second CU is associated with a particular priority, and the first CU may subscribe to updated information, maintained by the NRF, that is associated with the second CU. The first CU may receive, based on the subscribing, updated priority information associated with the second CU, which indicates that the second CU is no longer associated with the particular priority. The first CU may maintain, based on the updated priority information indicating that the second CU is not associated with the particular priority, an indication that the first CU is associated with the particular priority. The first CU may accordingly perform functionality that was previously performed by the second CU.

The system may identify network slice priority information that indicates relative priorities of the network slices, may select a particular network slice based on the network slice priority information, and may respond to the communication session request in accordance with the selected first network slice.

Abstract: A mobility management function residing in a visited Public Land Mobile Network (vPLMN) receives, from a Network Repository Function (NRF) residing in a home Public Land Mobile Network (hPLMN), a network address and/or a fully qualified domain name (FQDN) of a home network function (hNF) residing in the hPLMN. The mobility management function creates a network service request, associated with a User Equipment device (UE) that is roaming in the vPLMN, where the network service request comprises the network address and/or the FQDN. The mobility management function sends the network service request to a visited network function (vNF) residing in the vPLMN, and receives, via the vNF, results of execution of a network service by the hNF, and uses the results for handling the roaming UE’s traffic in the vPLMN.
