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).
