  • Publication number: 20190253407
    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.

  • Publication number: 20190166467
    Abstract: Methods and apparatus for use in establishing a group session in a mobile network for subscribers associated with a group are described. In one illustrative example, an access and mobility management function (AMF) entity receives, from a user equipment (UE), a request for registration which includes network slice selection assistance information (NSSAI). The NSSAI includes a group identifier associated with a group of subscribers. The AMF entity sends, to a unified data management (UDM) entity, a request for subscriber data which includes the group identifier. The AMF entity receives, from the UDM, a response to the request for subscriber data which includes a plurality of subscriber identifiers corresponding to the subscribers of the group. For a group session, the AMF entity creates a context associated with the group identifier and stores the context locally.

  • Publication number: 20190166016
    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).

  • Publication number: 20180343601
    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.

  • Patent number: 9661529
    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.
