The following procedure is an example of how to use the test set and an external PDSN simulator (MOB-IP-SIM) using Mobile IP protocol for IP packet data transfer. In this case, the test set will forward the PPP octets delivered by RLP data to the external MOB-IP-SIM. The MOB-IP-SIM is responsible for actual termination of the PPP link and interpreting all protocol layers necessary to pass the end-to-end encapsulated IP packets directly onto the network (IP, UDP, MIP).
This procedure will demonstrate how to access the MOB-IP-SIM built-in web site via the RF interface using a 1xEV-DO wireless device (such as an access terminal) as a wireless modem. The access terminal will be connected to the USB port on a laptop computer (PC) running USB port software developed by the manufacturer of the access terminal. The Wireless Protocol Advisor (WPA) can be used for logging the protocol messages during the packet data transfer. See Test Set's Mobile IP Solution Setup for a typical setup.
If you want to use the test set's internal PDSN simulation without the need of an external PDSN simulator for packet data transfer, see Packet Data Service Example Procedure (via Simple IP) .
The purpose of this procedure is to serve as an overview of the tasks required for a typical data channel application using the mobile IP protocol. If your particular application involves accessing internet or intranet sites via the MOB-IP-SIM's LAN interface, additional requirements such as getting through corporate firewalls may complicate setup procedures.
Refer to the Test Set's Mobile IP Solution Setup for a typical connection.

In this example, the home IP Address of your access terminal is obtained from the external PDSN (MOB-SIM-IP) instead of from the test set's DUT IP Address setting. Refer to the MOB-IP-SIM technical manual to properly configure the Home Node IP address for your access terminal.
Now, the test set setup are ready for a dial-up connection from the PC.
To access the MOB-IP-SIM built-in web site, open the web browser (for example, Internet Explorer) on your laptop and enter the MOB-IP-SIM's IP address (for example, http://188.8.131.52). The browser should display the MOB-IP-SIM's internal web home page:
