Abstract
Abstract In one aspect of the present invention, an integrated authentication center is provided that may be used in an exemplary integrated wireless telecommunications system (14). The integrated authentication center includes an application process, such as a call processing application (54), that includes a plurality of software objects such as a home location register (44) and an authentication center (42). The home location register (44) is implemented in one of the plurality of software objects of the application process and initiates the generation of an authentication set, such as authentication triplets. The authentication center (42) is also implemented in one of the plurality of software objects of the application process and generates the authentication set in response to the home location register (44).
