Introduction
This is the APTN Test Plan for Network Ready devices.
This document specifies protect-the-network test cases for protocol layers 4-7. The goal is to identify device
and/or application behavior that may either cause harm to the network or cause the network to operate
sub-optimally.
Clearly it is not possible to build test cases to identify every possible form of abnormal or suboptimal
behavior that a device or application may engage in, particularly as many applications are device or vendor
specific. This test plan therefore focuses on topics that historically have led to issues across a wide range of
devices, including DNS protocol operation, TCP protocol operationand packet transfer during nominal idle
times.
The test environment can be broken down as follows:
� The device under test (DUT) connects into a base station simulator platform (noted below) using a
test SIM as specified in Section 8 of Error! Reference source not found.. Either 2G or 3G or 4G
radio access can be used and a conducted RF connection is recommended.
� The DUT supports
tcpdump
, whereby a pcap file can be captured as the DUT operates on the live
production network. A protocol analysis tool such as Wireshark can then be used to capture layer
4-7 messages being sent from/to the DUT.
AT&T has validated two non-LTE platforms for this test plan:
� The Anritsu MD8470A Signaling Tester running Wireless Network Simulator (WNS) software as the
base station simulator. Device vendors wishing to use the same test environment can send an
email to MD8470-umts.Support@anritsu.com with subject line “MD8470A Media Net Configuration
Guide Request” to obtain detailed configuration instructions.
� The Rohde and Schwarz CMU 200 in conjunction with an external PC. Device vendors wishing to
use the same test environment can send an email to info@RSA.Rohde-Schwarz.com or telephone
1-888-837-8772 to obtain detailed configuration instructions.
AT&T has validated one platform for LTE for this test plan:
� The Anritsu MD8475A Signaling Tester running Wireless Network Simulator (WNS) software as the
base station simulator. Device vendors wishing to use the same test environment can send an
email to MD8470-umts.Support@anritsu.com with subject line “MD8475A Media Net Configuration
Guide Request” to obtain detailed configuration instructions.
Alternative implementations are possible, but are not supported by AT&T.
