Abstract

See full text

A network connectivity status of user equipment (UE) is detected. Detection of the network connectivity status of the UE may include, for example, detecting termination of network connectivity of the UE responsive to a communication to the network by the UE, receiving a termination message from the UE at the bootstrapping server function (BSF), receiving notification of de-registration of the UE from a home subscriber server (HSS) and/or detecting a loss of communications between the UE and the network. A bootstrapping server function (BSF) communicates with at least one network application function (NAF) responsive to detection of the network connectivity status to terminate a plurality of sessions associated with the UE.
