Abstract: Systems and methods provide for network-initiated recovery from a failure during transmission of text messages (e.g., Short Message Service or SMS) sent from circuit-switched (CS)/packet-switched (PS) infrastructure to a Mobile Station or User Equipment (MS/UE) connected to a PS radio access network. A text message service center (e.g., SMS Center or SMSC) can receive a message destined for the MS/UE. The SMSC can request from a home location register (HLR) routing information to a first text message interworking function (e.g., SMS-IWF) associated with a first visitor location register (VLR). The SMSC can receive data indicating that the first SMS-IWF/VLR is unreachable. The SMSC can transmit to the HLR an indication of an absent subscriber causing the HLR to request a Mobility Management Entity (MME) to reattach the MS/UE to a second SMS-IWF/VLR. In some embodiments, the MS/UE may reattach only to the second SMS-IWF/VLR (e.g., instead of a full reattach).

Abstract: In one embodiment, a device receives data regarding a node from a plurality of management platforms, each management platform being associated with a different access network used by the node. The device applies a unified data model to the data regarding the node received from the plurality of management platforms, to form unified data regarding the node. The device analyzes the unified data regarding the node, to generate insight information. The device provides the insight information to an application associated with a manufacturer of the node.
