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: A network device such as a network function (NF) entity or an application function (AF) entity in a communication network monitors network traffic for a plurality of peer-to-peer transactions associated with an application, where each peer-to-peer transaction includes communications between a user and a peer in the communication network. The network device also determines a set of geographic locations corresponding to one or more peer endpoints for the plurality of peer-to-peer transactions based on the network traffic, and determines an optimal midpoint between the set of geographic locations. The network device further deploys an edge node in the communication network to serve a subsequent peer-to-peer transaction for the application based on the optimal midpoint.

Abstract: Methods are provided to preemptively reconfigure a mobile network to respond to external emergencies. The method is performed at a network device of a service provider which provides access to a mobile network for wireless device. The method includes obtaining a message indicating an occurrence of a disaster. The message includes at least an emergency type and location information. The method further includes determining, based on the emergency type, a reconfiguration policy for reconfiguring the mobile network in an area indicated by the location information and reconfiguring the mobile network based on the reconfiguration policy. The method further includes authenticating a disaster application function and a notification message informing about an occurrence of a disaster.
