1. A method, comprising:
- receiving, by a convergence server, a call request for a mobile station communicably coupled to a femtocell system;
transmitting, by the convergence server, an invite message to the femtocell system;
receiving, from the femtocell system by the convergence server, a paging authentication request created by the femtocell system, the paging authentication request comprising authentication data received from the mobile station by the femtocell system;
generating, by the convergence server, after the mobile station is registered with the femtocell system and authenticated by the convergence server, an authentication token used by the convergence server to validate subsequent invite response messages;
transmitting, by the convergence server, a global challenge response to the femtocell system, wherein the global challenge response includes the authentication token, and wherein the global challenge response includes an indication of authentication success or failure corresponding to a mobile core network; and
determining, by the convergence server, whether the authentication token is present in the subsequent invite response messages received from the femtocell system for the mobile terminated voice call to the mobile station and denying by the convergence server the establishment of session initiation protocol (SIP) calls if the authentication token is not received.

Abstract
A system, method, and computer readable medium that facilitates processing of mobile-terminated voice calls for a mobile station attached with a femtocell system are provided. A convergence server deployed in a core network receives a call request for a mobile station attached with a femtocell system, performs validation of the mobile station against a subscriber profile maintained by the convergence server, transmits a Session Initiation Protocol Invite message to the femtocell system, receives a paging authentication request, and engages a mobile core network in an authentication process for the mobile station.

9. A non-transitory computer-readable medium having computer-executable instructions tangibly embodied thereon for execution by a processing system, the computer-executable instructions, that, when executed, cause the processing system to:
-
receive, by a convergence server, a call request for a mobile station communicably coupled to a femtocell system; transmit, by the convergence server, an invite message to the femtocell system; receive, from the femtocell system by the convergence server, a paging authentication request created by the femtocell system, the paging authentication request comprising authentication data received from the mobile station by the femtocell system; generate, by the convergence server, after the mobile station is registered with the convergence server and authenticated by the convergence server, an authentication token used by the convergence server to validate subsequent invite response messages; transmit, by the convergence server, a global challenge response to the femtocell system, wherein the global challenge response includes the authentication token, and wherein the global challenge response includes an indication of authentication success or failure corresponding to a mobile core network; and determine, by the convergence server, whether the authentication token is present in the subsequent invite response messages received from the femtocell system for the mobile terminated voice call to the mobile station and deny by the convergence server the establishment of session initiation protocol (SIP) calls if the authentication token is not received. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system, comprising:
-
a convergence server; a mobile core network that includes an authentication center and a Home Location Register; and an Internet Protocol-based femtocell system that provides a radio access point for a mobile station, wherein the convergence server; receives a call request for a mobile station communicably coupled to a femtocell system; transmits an invite to the femtocell system; receives from the femtocell system a paging authentication request created by the femtocell system, the paging authentication request comprising authentication data received from the mobile station by the femtocell system; generates an authentication token used to validate subsequent invite response messages after the mobile station is registered with the convergence server and authenticated by the convergence server; transmits a global challenge response to the femtocell system including the authentication token and the global challenge response further including an indication of authentication success or failure corresponding to the mobile core network; and determines whether the authentication token is present in the subsequent invite response messages received from the femtocell system for the mobile terminated voice call to the mobile station and denies the establishment of session initiation protocol (SIP) calls if the authentication token is not received. - View Dependent Claims (17, 18, 19, 20)
