Claim:
1. A method of facilitating indirect routing of mobile-originated short messages for a mobile station attached with a femtocell system, comprising: receiving, by a convergence server deployed in a core network, a service request message for a mobile station attached with a femtocell system, the service request message being in relation to the sending of a short message from the mobile station, the service request message having originated from the femtocell system after the femtocell system receives an SMS origination message from the mobile station, the SMS origination message identifying a destination mobile device to which the short message will be sent; engaging, by the convergence server and responsive to receiving the service request message, a mobile core network in an authentication process for the mobile station; responsive to the authentication process, transmitting, by the convergence server, a global challenge response to the femtocell system, the global challenge response message including an authentication token generated by the convergence server; receiving, by the convergence server, a short message originated by the mobile station from the femtocell system, the short message identifying the device; determining, by the convergence server, whether the authentication token has been presented to the convergence server by the femtocell system and denying the service request message if the authentication token has not been presented to the convergence server by the femtocell system; and if the authentication token has been presented to the convergence server by the femtocell system, transmitting, by the convergence server, the short message to a home message center of the mobile station which thereafter transmits the short message from the home message center of the mobile station to a destination mobile center of the destination mobile device.
