Introduction
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 operation, vanity URLs and 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 using a test SIM from a
platform listed below. Either 2G or 3G or 4G radio access can be used and a conducted RF
connection is recommended.
� A 3G/4G data card using an activated production AT&T UICC is connected to the base station
simulator. Software specific to the data card employed is used to control and configure the data
card.
� A bridging configuration is used to allow the DUT to access AT&T applications using the data card
as transport. 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 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 [email protected] 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 [email protected] 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 [email protected] 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.

Deliverables
The test result deliverables to AT&T include the following:
� The 16706 document must be completely filled in denoting Pass, Fail, or N/A, for every test
procedure. When a test result is marked Fail or N/A, remarks must be included in the Comments
section to explain the reason for such.
� PCAP logs for each test procedure must be captured in separate files. These PCAP logs are to be
submitted to the AT&T DDA APTN SME for review.
� The 18214 document for the estimated data usage consumption must be completely filled out and
submitted to the AT&T VC for the AT&T DDA APTN SME to review.
� It will be extremely helpful to note which segments (timestamps and/or line numbers) map to each
validation point in the test procedure when a test fails. For example, indicating what line number
the tester invokes or reloads the browser. Placeholders for these notations have been embedded
in each test procedure in 16706. Please use them when a test fails.
Scope
The scope of tests in this document is limited to devices that can connect to AT&T’s wireless data
network.
The intended audience for this document is AT&T Subscriber Product Engineering, Regional Field
Test engineers and device OEMs.
