——Integrated Solution for Terminal Protocol Conformance Testing

1

Introduction to the ECT7310 Terminal Protocol Conformance Tester

The ECT7310 provides users with a terminal protocol conformance testing total solution.

It supports single-module protocol tests for TD-LTE-A、LTE FDD-A、TD-SCDMA, TD-LTE

, LTE FDD, IMS 、 VOLTE 、 SRVCC, as well as IRAT tests for

TD-SCDMA/GSM 、 TD-LTE/TD-SCDMA 、 TD-LTE/GSM 、 TD-LTE/LTE FDD 、 LTE

FDD/WCDMA 、 TD-LTE/WCDMA 、 LTE FDD/GSM 、 LTE FDD/WCDMA/GSM

、 TD-LTE/TD-SCDMA/GSM. This tester uses the Datang LinkTester latest hardware

platform, and meets all 3GPP terminal protocol conformance-related requirements

(TS34.123, TS51.010 and TS36.523).

ECT7310 is highly scalable and provides an integrated and automated testing solution

that will significantly increase usage rate/efficiency, thus reducing testing costs. Its strong

signaling parsing capacity and its locating function will speed the optimization of the

tested products. Currently, the ECT7310 is widely used and has been adopted by China

Mobile‘s Terminal Selection and Testing Lab, by China MIIT's China Type Approval(CTA)

as well as by various terminal and chip manufacturers (both for product development and

testing)

Main Features

Full support of terminal protocol conformance test specifications

Comprehensive protocol versions (including R4, R5, R7, R8 R9, R10 and R11).

Complete protocol stack, including PL, MAC, RLC,PDCP, RRC and NAS.

Services testing such as RAB ,SMS,IMS,VOLTE,FTP,HTTP.

Test scripts use TTCN. This script language allows for fast completion of 3GPP

compliant test-cases. Note that it supports a software interface (API)facilitating

the writing/coding of new test-cases.

Flexible configuration

Depending on the specific requirements of a given scenario, it is possible to

choose between single and multiple cells configuration, allowing for flexible

network simulation.

Depending on the requirements of a particular test scenario, users can select

4

the proper configuration by choosing from a large set of scenarios that come

preloaded on the tester .

Users can select manual test mode or automated test mode; there are multiple

automated test modes (including Normal, Loop and Retry on fail) so as to meet

the requirements of R&D, certification and production.

FADING inside，simulate real network communication scenarios，with flexible

signaling process and abundant application type.

Various positioning methods

The data monitoring system has the ability to display in real time the Uu

interface data information as well as the local configuration.

Automatic analysis of test procedures and automatic matching of failure points.

Support for customized shading rules, rapid filtering of log information,

customized display and classification, as well as clear and understandable log

generation.

Support for multi-functional combined queries of message logs using various

different standards (e.g. primitive, time and bit stream) so as to find the locating

message in a timely manner.

Perfect test reports

Real-time display of statistical charts, both during and after tests execution.

Test logs can be stored onto a local PC or uploaded to a remote server, as

required by users.

Test results can be saved in various formats (excel, pdf, word, txt and html).

Presentation of the ECT7310 Hardware and Software

ECT7310 Terminal Protocol Conformance Tester: hardware

The ECT7310 Terminal Protocol Conformance Tester comprises an LTE, a TD-

SCDMA and a GSM module.

LTE-A module

The LTE-A module allows for TD-LTE-A and LTE FDD-A ， forward

compatibility TD-LTE and LTE FDD， testing along 400MHz~3800MHz. All of

5

the bands frequently used in LTE are supported

(band20/07/04/03/01/38/39/40/41 etc.).

TD-SCDMA module

The TD-SCDMA module includes the baseband processing module (ECTC) and

the RF processing module (ECTU). ECTC is responsible for processing the TD-

SCDMA physical layer and the upper-layer protocol;

while the ECTU processes the TD-SCDMA RF signals that covers the

Band34(A)/Band39(F)/Band40(E) frequency bands.

GSM module

Introduction to the Software Environment of the ECT7310

Description of SMT Functions

SMT is the ECT7310 master control program. Users can customize the testing

library, create test tasks in random order, perform testing and monitoring, as

well as save the test results.

Menu bar Seven menu items: File, Edit, View, Test Plan, Tool, Window and Help. Users can create/open the Workspace, add UE/test plans, switch the display window, set associated parameters, start/pause/stop the execution of test plans etc.

Toolbar Comprised of three parts: Standard, Views, and Format. The toolbar is primarily used to create/open/close the workspace, add UE/test plans, switch the display window, start/pause/stop the execution of test plans, edit texts etc.

Status bar Displays various current SMT status messages, including the name of the current user, the connection status, the alarm message prompt, test-case execution progress bar, SAVE/UPDATE and other such message-prompts.

Workspace Comprised of five parts, namely Notes, Documents, User Terminals, Test Plans and Test Reports. It is primarily used to add/modify/copy/import and export/delete UE and test plans, execute test plans,view test reports etc.

Document space Display sequence executor, workspace-notes, PIXIT table, AT settings, test plan-notes and case sequence windows, provide functions such as text editing, case sequence editing, display both execution process and test results.

Log This bar has three windows, namely the SMT Log, the ADL Log and the TTCN Log. It is used to display and view on-going SMT log information and test-execution.

Sequence status Display in real time the running status information (execution result, execution mode, throughput rate, and time consumed historic records) about each case part of running Test Plan. The sequence status can also save and exportfailed tests as a Test Plan document.

Statistical chart Real time update of all statistical charts pertaining to completed and on-going Cases.

Description of Monitor Functions

As a data monitoring system, the Monitor can display in real time both data

information and local configuration for each layer of the air interface. It can

decode information and display it through a user-friendly viewing interface; it

also supports the simultaneous opening of offline message files. Additionally,

its display window includes functions such as message filtering, shading,

labeling, and lookup/search.

Menu bar There are seven menu items, namely Connection, Trace, View, Tools, Log, Window and Help.

Toolbar There are 4 items in the toolbar, namely opening offline log, start tracing, stop tracing and switch filtering modes.

Display window Display online and offline tracing messages.

Output window Primarily display output messages from the Monitor system itself.

Status bar Display the connection status of the card and the connection status of SMT.
