Abstract
Systems and methods are disclosed for correlating messages used to deliver an Application Originated (AO) text message to User Equipment (UE). A text message gateway is implemented between a text message application and a packet-switched network that uses Session Initiation Protocol (SIP). The text message gateway receives a delivery request from the text message application that includes an Application Originated (AO) text message intended for the UE. The text message gateway identifies a correlation identifier (ID) for the AO text message, inserts the correlation ID in a delivery response, and transmits the delivery response to the text message application (to store for later use). The text message gateway also converts the delivery request into a SIP request that encapsulates the AO text message, inserts the correlation ID in the SIP request, and transmits the SIP request to the UE.
