More Information
Summary:When a serving call session control function (S-CSCF) of a mobile network fails or is otherwise unavailable, over-the-top (OTT) services for a mobile terminating (MT) user equipment (UE) may be disrupted, as the network may lack routing information for sending invites and/or services to the corresponding OTT application(s). According to the disclosure, OTT services can be restored by sending an out-of-band message to an OTT application to cause that OTT application to reregister with the mobile network to establish new pathways for providing OTT services from the mobile network. An application server, in cooperation with a secure push proxy (SPP) system, can send push notifications to OTT applications of a MT UE when that MT UE is associated with OTT services and when the OTT applications are not registered with the mobile network. The push notifications cause the OTT applications to reregister with the mobile network to restore OTT services.
