  • Method And System Of Delivering An SMS Message
    Publication number: 20110105117
    Abstract: A Mobile Switching Center (MSC) receives a short message service (SMS) message from a mobile station. The MSC checks a link between it and an MME to see if the link is currently set. If the link is not currently set, the mobile station is re-registered at the MSC, which re-established the link between the MSC and the MME. The mobile station will resend the SMS message to the MSC, which now utilizes the re-established link to deliver the SMS message.
