Abstract
There is disclosed an interworking function unit for transferring data between a wireless network and an Internet protocol (IP) data network coupled to the wireless network. The interworking function unit comprises a protocol conversion controller that receives incoming data packets from the wireless network, wherein the incoming data packets are generated by a first mobile station and are formatted according to a protocol associated with the wireless network. The interworking function unit converts the incoming data packets to IP data packets formatted according to an Internet protocol of the IP data network. The interworking function unit also comprises a first security controller for preventing unprovisioned mobile stations from accessing the IP data network through the wireless network. The first security controller receives the IP data packets and replaces each original IP packet header with a replacement IP packet header containing the IP address of a provisioning server.
