Abstract
Systems and methods for determining the availability or reachability of mobile devices to receive text messages. One embodiment comprises a message entity of a Long Term Evolution (LTE) network. The message entity attempts delivery of a text message to a mobile device, and determines that the delivery attempt failed due to the mobile device being temporarily unavailable. The message entity transmits a request to a Mobility Management Entity (MME) of the LTE network to be notified when the mobile device becomes available. The message entity receives a notification from the MME that the mobile device is available, and retries delivery of the text message to the mobile device responsive to the notification from the MME that the mobile device is available.
