ABSTRACT:
The present embodiments provide a system and method for seamlessly roaming between different wireless access technologies. In an exemplary embodiment, a universal wireless access gateway (UWAG) may include a shared component and a first environment access module (EAM) that communicates with the shared component to enable access to a first network using a first wireless access technology. Additionally, the UWAG may include a second EAM that communicates with the shared component. The second EAM and shared component may enable access to a second network using a second wireless access technology that differs from the first wireless access technology. An exemplary data structure including various pointer blocks and data blocks may also be provided for switching between different wireless access technologies.
