Abstract: In some implementations, a message indicating a request for delivery of data to user equipment (UE) (e.g. an IoT device) operative for communications in a mobile network may be received from an application server. One or more first loading or congestion indication values indicative of a first loading or congestion at one or more first network nodes along a first mobile network route may be obtained. In addition, one or more second loading or congestion indication values indicative of a second loading or congestion at one or more second network nodes along a second mobile network route may be obtained. The first or the second mobile network route may be selected based on at least one of the one or more first and the second loading or congestion indication values. The data may be delivered to the UE over the selected mobile network route.

Abstract: A method is provided in one example embodiment and may include receiving congestion information for an environment in which a user equipment (UE) is operating; receiving a first request to deliver content to the UE; determining that the environment in which the UE is operating is experiencing congestion based, at least in part, on the congestion information; determining a re-try interval based, at least in part, on the congestion information; and deferring delivery of the content to the UE until the re-try interval has expired. In one example embodiment, the method can include provisioning one or more policy rules for a service data flow associated with the content and communicating the indication indicating that delivery of the content has been deferred to a charging system to set charging information for at least one of a user associated with the UE or a provider of the content.

Abstract: Presented herein is a Security Edge Protection Proxy (SEPP) fully defined as a 5G network function (NF) that registers and is discoverable by consumer NFs. Inter-Public Land Mobile Network (PLMN) roaming connectivity polices enable the SEPP in the visiting PLMN to select the SEPP per producer NF-Type in the home PLMN, and to select a direct route between PLMNs or an indirect route via one or more an Internetwork Packet Exchange (IPX) providers.

Abstract: A policy enforcement technique may be performed at a network node configured for exposure of services and capabilities, such as a service and capability exposure function (SCEF) or a network exposure function (NEF). In one illustrative example, the network node may receive a message which includes a request for background data transfer from an application server (AS) to a plurality of UEs of a group. The message may include mobile-terminated (MT) data to be delivered, a group ID associated with the group, a total bandwidth for the background data transfer for the group, and a transfer policy ID associated with a transfer policy. The network node may verify whether the total bandwidth for the background data transfer for the group is within a predefined aggregate bandwidth limit indicated in the transfer policy data. The network node may cause the background data to be sent to each one of the plurality of UEs via the mobile network, if the total bandwidth is within the predefined aggregate bandwidth limit. In some implementations, the network node may be configured to facilitate background data transfers and perform policy enforcement for transfers involving both IP data delivery and non-IP data delivery (NIDD).

Abstract: A network function (NF) profile repository function (NPRF) is provided to receive, for each one of a plurality of NF instances of a plurality of different NF types, information associated with the NF instance and store the information in memory. The NPRF may then also receive, from an NF repository function (NRF), a message which indicates a request for information associated with one or more NF instances of an indicated NF type. In response, the NPRF may retrieve, from the memory based on the indicated NF type, information associated with the one or more NF instances. The NPRF may send, to the NRF, a message which indicates a response to the request, where the response includes retrieved information associated with the one or more NF instances.

Abstract: Single sign-on (SSO) techniques of the present disclosure provide for enterprise application user identities that are bound to a mobile identity (e.g. IMSI) associated with a user equipment (UE) for authentication, using general bootstrapping architecture (GBA)/general authentication architecture (GAA) functionality in combination with identity provider (IDP) functionality (e.g. OpenID Connect), all of which may be provided in an enterprise network. The present techniques need not rely on GBA/GAA infrastructure of a mobile network operator (MNO), and have little or no impact or effect on the mobile network.

Abstract: In one embodiment, an enterprise network includes: at least one wireless access point operative to enable a wireless device to connect to the enterprise network, networked resources to be accessed by the wireless device, and a network selection server implemented on at least one computing device and operative to: authenticate credentials provided by the wireless device when connecting to the enterprise network via the at least one wireless access point, and provide network access selection policies to the wireless device, where the network access selection policies at least determine access by the wireless device to network resources while said wireless device is connected to said enterprise network.

Abstract: Subscription-based, user equipment (UE) event notification techniques for use in a mobile network are described. In one illustrative example, an event subscription request from an application server may be received at a network exposure function (NEF) entity of a 5G mobile network. The event subscription request may include a list of one or more subscribed events for a UE, which may include a UE attach event and/or a UE detach event. A context which indicates the one or more subscribed events may be created for the UE. Sometime during network operation, an indication of an occurrence of an event associated with the UE is received. The indication is received from a policy and charging function (PCF) entity when the UE is configured for IP data delivery, or from an access and mobility management function (AMF) entity when the UE is configured for non-IP data delivery (NIDD).

Abstract: The present disclosure is directed at systems, methods and media for mitigating congestion for roamers in a wireless access network. In some embodiments, Radio Access Network (RAN) congestion information is reported from a base station to a RAN Congestion Awareness Function (RCAF) of a visited network. The RCAF can mitigate congestion by controlling Quality of Service (QoS) parameters for roaming User Equipment (UE) in a congested cell. The RCAF can further communicate with the Mobility Management Entity (MME) of the visited cell and the Policy Charging and Rules Function (PCRF) of the UE's home network. The RCAF can relieve congestion for roamers without informing the home network of the congestion at the cell.
