Method and System for SMS Communication in 3GPP Networks
A User configures the option in his/her UE to deliver the SMS via Operator's application client installed on UE. This configuration will be saved in the UDM as an option opted by UE. SMS-GMSC receives the “SMS delivery flag (indicating alternate delivery mechanism is enabled)” from UDM in response to the “Send Routing Infor for SM” message. If the traditional SMS delivery over mobile operator network fails (e.g. no connectivity), then SMS-GMSC will trigger NEF to re-attempt the SMS delivery to UE. (NEF can be an optional network function as Application function is trusted one and hosted in Operator's network). NEF sends the SMS to Application Function (Mobile Network Operator's Serer) which encrypts the SMS payload and delivers the SMS to operator's application client e.g. Mobile Network Operator App installed on UE over the alternative data connectivity (Ex.

Therefore, if the User has data connectivity by alternative means (via different channels like Wi-Fi hotspot, Home Wi-Fi broadband, another Operator SIM etc.), it should be possible to deliver an SMS update on Operator's application client installed on UE.
