Packet Data Service Example Procedure (via Mobile IP)

Last updated: August 31, 2009

This section is only applicable to the lab application.

The following procedure is an example of how to use the test set and MOB-IP-SIM for IP packet data transfer using mobile IP protocol. For example procedure over simple IP protocol, see Packet Data Service Example Procedure (via Simple IP) .

This procedure is to demonstrate how to access the MOB-IP-SIM built-in web site from the mobile station via the RF interface using packet data service. The Wireless Protocol Advisor (WPA) can be used for logging the protocol messages during the packet data transfer.

The purpose of this procedure is to serve as an overview of the tasks required for a typical data channel application via the mobile IP connection. 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.

1. Ensure the mobile station is pre-programmed with known parameters.
2. Refer to the MOB-IP-SIM technical manual to properly configure the MOB-IP-SIM (for example, IP address, subnet mask, etc.).
3. Connect the mobile station support of mobile IP protocol to the test set's front panel RF IN/OUT connector. Connect the test set, the MOB_IP_SIM, and the PC running a web browser to a LAN. See Configuration for a Mobile IP Solution
4. Power on the test set. Press SYSTEM CONFIG , then press F1 ( Instrument Setup ), set the LAN IP Address , Subnet Mask , Default Gateway for the test set which are assigned by your network administrator (See IP Address Requirements ). Note that the LAN IP Address 2 (Data+) should be set properly if the test set supports the LAN 2 PORT .
5. Select SO33 or SO33 (+F-SCH) for the selected Radio Config: (Fwd3, Rvs3), or (Fwd4, Rvs3) from the FCH Service Option Setup ( F12 on Call Parms 1 of 4 ).
6. Set the test set to use external PDSN (See How Do I Set Up Data Channel Parameters? ):
   • Set the External PDSN IP Address to the same value of the MOB-IP-SIM you've set in step 1.
   • Set the External PDSN TCP Port to the default value (currently, the TCP port for the MOB_IP_SIM is fixed to 53613)
   • Set the External PDSN State to On
7. If you would like log the protocol messages exchanged between the test set and the mobile station as data is transferred, set up the Wireless Protocol Advisor (WPA) (running on the PC) and start logging. See Protocol Logging .
8. Power on the mobile station and wait for the mobile station to perform a power up registration. You may need to change some settings as required for your mobile station (such as Cell Band, Channel, SID, etc.) to allow the mobile station to find service. See How Do I Set Up an IS-2000 Call? .
9. After the mobile station finds service, navigate to the web browser on the mobile station. Using the web browser, attempt to access the web site built in the MOB-IP-SIM. This step depends upon the mobile station implementation.
10. Monitor the Active Cell call status (see Packet Data Connection Processing States ), the mobile station display, the Counters window (see Data Counters ), and the Data Throughput Monitor window (see Data Throughput Monitor ), as well as the WPA (if started) as data is transferred. These tools are useful for analyzing data transfer rates under various RF and call processing conditions.
