A system, method, and computer readable medium that facilitates delivery of mobile-terminated short message service messages to a mobile station attached with a femtocell system are provided. A convergence server deployed in a core network receives a short message for short message service delivery to a mobile station attached with a femtocell system. If there is no active traffic channel with the mobile station, or if the short message is to be delivered to the mobile station via a paging channel, the femtocell system triggers an authentication process. The convergence server constructs a short message service delivery request message, transmits the short message service delivery request message to the femtocell system, and receives one of an acknowledgement and a negative acknowledgment regarding delivery of the short message to the mobile station. The convergence server thereafter notifies the message center of the acknowledgment or negative acknowledgement received thereby.
