Abstract
Systems and methods described herein provide routing determinations for MT-SMS-over-NAS in core networks that support 5G and legacy systems. A network device stores routing priority data for multiple short message service (SMS) delivery methods in the core network. The network device receives, from a first network element, a delivery request for a mobile-terminated (MT) SMS message directed to an end device and sends, in response, a query to a second network element. The query requests a short message service function (SMSF) address for an SMSF in the core network with which the end device is registered. The network device receives a response to the query and selects, based on the response and the stored routing priority data, an SMS delivery method for the MT SMS message. The network device sends, to a third network element, routing instructions for the MT SMS message based on the selected SMS delivery method.
