Ubiquitous Wireless Coverage

LTE (Long Term Evolution) is fast becoming the front runner for next generation, with many legacy systems and even variants being integrated. The challenge for terminal developers is to back the winners and also be able to support the other systems to be sure of globally connected devices.

With budgets being cut, and effi ciencies examined, it is not an option to continue using traditional methods for development of modern wireless terminals. The multitude of applications expected to work on ever changing and developing networks, means test systems need to be comprehensive and fast to adapt and react.

- the next challengeAnritsu has been at the leading edge of 3rd Generation mobile development programs and is now delivering Intelligent Test Solutions for LTE development teams that need to accelerate their designs to stay competitive. With fi rmly established R&D centres in Europe, Japan and North America, Anritsu can claim to be a truly International company with in-house expertise that no other company can match.

RTD is designed to simulate the many different networks that may be deployed with LTE: like W-CDMA, GSM and C2K based technologies. It can also be integrated into systems that go beyond “over the air protocol” and provides performance and evaluation of many

other critical parameters.

The graphical fl ow chart method provided by RTD is now adopted by many development teams, who have recognised the time savings and test coverage it can provide.

Anritsu has a mature customer base of 3G installations using the MD8480C W-CDMA Signalling Tester and is now able to provide a cost effective solution to migrate over to LTE with the MD8430A LTE Signalling Tester. This combination makes a comprehensive and fl exible solution for the most powerful protocol development system for next generation wireless terminals.

The RTD is already established as a proven multi-standard graphical fl ow chart tool for many organisations. MD8480C has now become a reference as an essential part of test systems refl ected by its extensive use in all aspect of the 3G terminal development cycle including R&D, integration, regression, conformance, interoperability and validation. It has the ability to create almost limitless network simulations and is now complimented by the MD8430A for LTE and MD8470A for cdma2000.

The RTD is the fastest and most effi cient way to ensure that modern terminal behaviour can be comprehensively exercised. Its ability to simulate network scenarios with actual network settings takes it beyond conformance testing and into real world situations.

Network Operators are making use of the RTD’s intelligent test tools to ensure that terminals behave correctly on their networks. Terminal development teams simulate conditions in networks that may be thousands of miles away and may not yet support the new functionality present in new handsets hence saving time and money.

We travel the world and expect to be able to talk, text, browse and more importantly be informed wherever we are. “Staying connected” is now the norm.

Wireless technologies all compete and collaborate for market share and although GSM started a trend for a Global Standard, many competing systems now appear to provide alternative or hybrid systems.

TERMINAL DEVELOPMENT from R&D to Conformance and Beyond

R&D teams will spend thousands of hours developing, integrating and proving their terminal designs. The RTD now provides LTE design teams with procedures that test low level confi guration as well as L3 protocol.

Individually the procedure libraries provide tools for teams at different parts of the design process. By combining and merging them, very detailed proving and integration of designs is possible.

As specifi cations evolve, the RTD provides a roadmap that refl ects the fast moving needs of the developers. As a consequence increased dependence upon regression testing will be required to ensure changes do not affect the designs. RTD provides all the tools for immediate test defi nition, analysis and execution.

Maintaining Tests

Wireless terminal developers will build up large libraries of tests for ongoing development and regression testing of their designs. The RTD has the ability to update these libraries using the latest 3GPP Release automatically, saving many hours of test re-creation and debugging.

Beyond ConformanceAlthough conformance tests prove adherence to specifi cations, they play little part in simulating “real world” conditions where consideration to interfering signals and user plane data is involved. The RTD makes test scenarios easy to create and then iterate as there is no lengthy compilation stage and tests may be adjusted at run time if required.

Roaming and Network SelectionWith multi-mode capability, terminals will have complex algorithms that select preferred networks and still maintain acceptable performance. Revenue streams will be threatened if UEs do not behave correctly and Network Operators will exercise them to ensure the best possible behaviour on their network confi gurations. RTD provides this type of testing which will be crucial to terminal selection - and rejection.

Simulating Live Network ConditionsTraditionally protocol and RF tests have been kept separate. In order to reduce test times there is a trend to combine fading with protocol tests. The RTD provides a convenient way to add digital baseband fading by Using the MF6900A Fading Simulator to the system.

Where Does TTCN Fit InMany developers will need to adopt TTCN3 for conformance and Anritsu supports TTCN-3 with its PCTS (Protocol Conformance Test System). TTCN is a powerful language for conformance testing, however it becomes cumbersome and time-consuming when many different test variants are required. Keeping track of version control and syntactical problems during development is a task in itself. A modular solution like RTD which allows simple test and variant creation is essential to improve effi ciency.

Time to MarketWith competition being so great and staff movement an issue, teams cannot afford to add time to development of new products. The RTD provides an intuitive interface that is easy to learn and provides fl exible and informative feedback to the operator. This allows developers to accelerate the learning curve for new technology and the tools needed for successful designs.

Regression TestingRegression testing also needs to be performed as new software is introduced into networks. RTD makes it possible to modify test scripts simply by applying a new set of network parameters or making a change to a reference that can populate a suite of tests. The test suite can then be run overnight or unattended, presenting the operator with an executive summary to enable software stability trends to be mapped.

With fi nite bandwidth and ever more traffi c generated, the biggest challenge is for network operators to optimise their networks and ensure that terminals obey the rules they set. LTE attempts to make more effi cient use of the spectrum available but still needs to inter-work with legacy systems. There are also regional variations and network specifi c requirements that terminals will be expected to conform to. Load balancing may be important to make best use of network resources and although aesthetics and applications may defi ne a terminal’s popularity, the behaviour under specifi c conditions needs to be tested to ensure a reliable and friendly user experience.

Cell Selection and Re-SelectionThe compromise between battery life and continuous caretaking activities will always challenge terminal designers. Thousands of hours of fi eld trials may still not be able to identify why a terminal fails to maintain service on a preferred network.

Many conditions can only be reliably exercised using a simulation of network conditions in the laboratory. The RTD has the ability to use network logs and create tests that closely resemble the fi eld environment. Iteration of the test is then straightforward to discover and rectify the problem.

Application TestingAs we move to an all packet delivery network, data throughput and integrity is becoming more important. Scenarios with a variety of radio bearers and confi gurations is possible with RTD, proving that data is not lost during handovers and reselection.

As traffi c builds up and volume driven state transitions occur the user needs to remain connected.

Simultaneous applications are now commonplace, so interaction and priority between services needs simulating.

Where high value applications such as fi nancial transactions take place handovers or link failures may be serious. Gaming and social networking may seem less important to test, but is proving to be a differentiator for a young and infl uential market.

Roaming PartnersSimulation of foreign networks using the RTD’s many advanced features allows a convenient way to test roaming between networks with different confi gurations / parameters and even different ways of implementing procedures. Today the cost of sending engineering teams to perform network testing over many weeks can be a very signifi cant portion of a Network Operator’s proving budget.

New Network Services Most Networks will not allow new terminals onto their live service without some proving. RTD provides a way to test new terminals and also new services that may be ready to be deployed. Future functionality and applications can be proved in a controlled way using a system simulator and problems resolved ahead of deployment.

Stress TestingTerminal stress testing can be automated and run overnight using RTD. With the ability to make thousands of reselections, calls, hand-overs etc. Tests that exercise the extremes and limits of the terminal provide quantitive and qualitative data for terminal selection.

Acceptance Testing for Network Operators

InterRAT TestingMost Network Operators will be adding LTE to their existing infrastructure and will be looking for an evolutionary path forward. Existing GERAN/UTRAN tests written for the MD8480C may be used as part of the overall test strategy for the new network.

The RTD is able to perform InterRAT tests by controlling both MD8480C, MD8470A and MD8430A platforms. Existing tests can be updated and used as a basis for LTE inter-working.

Although high peak data rates grab headlines, the objectives of LTE are as much about increasing effi ciency and reducing costs as achieving high performance. Great efforts are being put into creating a global standard to achieve global economies of scale. Despite this, the 3GPP Rel-8 LTE networks will see regional variations in deployment. Different frequency bands will be used in different parts of the world. Different LTE modes (FDD and TDD) also will be used. And, different legacy networks will be used for fall-back—GSM/GPRS/WCDMA/cdma2000. RTD will evolve with future requirements and aims to provide updates every 3 months to ensure tracking of new requirements.

The results can be presented in many formats

The RTD’s unique fl owchart display provides a more natural way of creating scenarios and observing test fl ow and outcomes.

Debugging is especially straightforward as tests can be run and iterative changes made. Because there is no compilation phase, tests can be run immediately and aborted if the wrong path is taken.

With well annotated tests, sharing and consolidation is possible and productive.

The RTD Test System for multimode terminals is a complete solution checking the behaviour of terminals in development and before they are deployed on live networks.

The RTD presents an intuitive and interactive graphical environment for designing test cases, coupled with an expert system that guides the user through the intricacy of 3GPP protocols. This hides much of the complexity of testing 3GPP protocols and allows the user to concentrate on testing specifi c functions and applications within the terminal without having to be an expert on all the protocol layers or TTCN programming.

It is built upon Anritsu’s many years of experience in testing 3GPP protocols with the leading terminal vendors.

RTD can be used for a wide variety of purposes:

Acceptance Testing •

Integration Testing •

Interoperability Testing •

Generating Variants •

Application Testing •

Regression Testing •

Pre conformance Testing •

Prototyping Tests •

The RTD provides many ways that test execution can be made more effi cient using remote control, terminal control and campaign management tools.

The RTD may be controlled using remote commands and integrated into a total test system. The RTD is compatible with a number of remote commands that allow Tests to be RUN, ANALYZED, etc. In this mode the RTD works as a slave to an existing test system where existing equipment and data is controlled and collected.

The RTD provides proxy control of the AT command set to the terminal through the RTD Test Cases. It enables automated testing to be achieved through a serial port on the control PC. An appropriate proxy.xml fi le is applied to map the AT/MMI commands to match those supported by the terminal. Prompts on the screen can be suppressed when automation is used. In general automated testing can be carried out via the use of the AT command set [3GPP TS27.007]

For some, the RTD will be a new concept and we aim to provide the tools and support to make the experience productive and logical.

Using the RTD

An RTD test is constructed and edited using a graphical environment, which supports procedures, loops, delays & interactive dialogs. Compared to traditional “C” and “TTCN” based languages this GUI provides fast and simple test creation. Typically a test that may have taken several days to create may be created in hours using the RTD.

Reference Tests

These reference tests are samples of commonly used functions to act as templates for the user. They allow Network specifi c parameters to be added manually or by means of a “catalogue” function. Packages of other test cases are also available on request.

Test Execution Engine

RTD tests are run immediately after they have been checked for simple errors, without a compile or build cycle.

Test Criteria Editor

The test operative may use this tool to automatically make objective decisions on whether the right actions have been made by the UE. Criteria may be changed post testing and applied to existing results. This avoids the need to re-run the tests.

The Total System Solution

Detailed Test Log Analyzer

The protocol log analyser, which maintains the same look and feel as other Anritsu products, is provided to examine the message sequences that are produced by the terminal under test.

Procedure Libraries

Procedures are the building blocks from which all tests are created. The RTD Procedures can be selected from a palette and added to the User Test simply by dragging onto the edit page. Compound procedures can be created to allow frequently used scripts to be added in a single action, further simplifying test creation.

These procedures are confi gured using parameters, which can be changed at three levels :

1) Parameter sets held in catalogues can be selected to parameterise groups of procedures rapidly.

2) The user can edit individual parameters after they have been selected from catalogue components, overriding values if they wish to. These parameters are used to populate the actual protocol messages sent by the procedure.

3) The expert user can edit the individual messages sent by the procedure, if needed, overriding any parameters previously selected or changed.

Wireless terminals will continue to evolve and in order to keep in touch with market changes and 3GPP specifi cations, the RTD has a full suite of support and training options to suit different users and applications. This allows users to gain the most benefi t from the product and in turn to increase productivity and maximize revenue.

Software Update and Maintenance Contract

Customers are encouraged to take out software update and maintenance contracts to ensure that they keep up with both the latest software features and tracking with the latest 3GPP version supported. Approximately every three months a new version of the RTD software is introduced and made available to all participants in the scheme. The updates are available electronically and come with full release documentation to ensure backward compatibility with existing tests.

Premium Support

Anritsu provide access to their engineering support for users that reach a critical milestones or require specialist assistance during development and proving of their terminal designs. This can be purchased on a per day basis and can be arranged in advance where it needs to be planned into a development program and can even be supplied as an on-site activity if required.

On Site Installation and Commissioning

Installation and commissioning is usually expected to take approximately one day. This service is offered in addition to the initial training for the product.

Cost of Ownership

Using the On-Line Help & Tutorials

Using the on-line help and tutorials allows fi rst time users to get the most from the system. The tutorials are designed to guide them through many of the unique features and help understand the architecture and operation of the system.

Training

Training courses are available for the RTD and comprise a combination of classroom and practical activities. Training can be provided either at the customer site or at Anritsu facilities. This training should not be seen as a substitute for comprehensive training on the 3GPP protocol although the tool itself is an excellent way of learning.

Support Desk

Where possible we provide local support in territory or from a local fi eld offi ce. This is the fi rst line of support, which is backed up from our International support desks. From day one we aim to provide an effi cient support service and fast response time to technical questions.
