Method and apparatus for supporting wireless data services on a TE2 device using an IP-based interface
Abstract:
A wireless network assigns a single IP address to the wireless device, which assigns this IP address over to a TE2 device coupled to the wireless device. The wireless device derives a private IP address for communication with the TE2 device. The wireless device forwards packets exchanged between the TE2 device and the wireless network using the single IP address. The wireless device exchanges packets with the TE2 device by (1) using the private IP address for outbound packets sent to the TE2 device and (2) performing either address-based routing or packet filtering on inbound packets received from the TE2 device. The wireless device exchanges packets with the wireless network by (1) using the single IP address for outbound packets sent to the wireless network and (2) performing packet filtering on inbound packets received from the wireless network.
