Abstract
Techniques are disclosed for correlating delivery receipt (DLR) messages with short message service (SMS) messages sent in an application-to-person (A2P) manner through a messaging network comprising multiple data centers. SMS and DLR messages are received and stored into a correlator comprising a local and a global storage area. It is then determined whether a received DLR message corresponds to a received SMS message within a local timeout period associated with the received SMS message. When corresponding DLR and SMS messages have been received they are correlated and the DLR message is sent to the sending SMS client. When corresponding DLR and SMS messages have not been received the location of a global storage area of a correlator in a data center where the DLR and SMS messages are intended to be stored is derived. The DLR and SMS messages are then moved to the derived global storage area of the correlator in a data center where it is again determined whether a received DLR message corresponds to a received SMS message within a global timeout period associated with the received SMS message. When corresponding DLR and SMS messages have not been received within the global timeout period, a fail notification is sent to the sending SMS client. Other embodiments are disclosed.
