Simulation and Emulation Applications To Assess System Performance Under Controlled Conditions

Tools for Functional, System and Conformance Testing

The K1297-G20 Protocol Tester combines simulation and emulation tools, such as test suites and traffic generation, with monitoring capabilities to address functional testing applications. The K1297-G20 Protocol Tester is a comprehensive, configurable platform for intrusive and non-intrusive protocol testing and analysis in communication networks, especially in mobile networks.

Test generation capabilities provide the means to simulate specific protocol layers and emulate all underlying layers automatically, or even to emulate the full functioning of network elements. The K1297-G20 features the ability to generate traffic on almost all interfaces and to mix technologies in one test scenario, a vital advantage in interworking, and interoperability testing for the optimization of resources.

Simulation and Emulation Application Examples

Predefined Message Flows. The K1297-G20 is able to send an individual message or handle a predefined message flow, such as conformance tests or individually developed test cases.

Layer Emulation.The K1297-G20 provides the functionality of a specific protocol layer which behaves like the corresponding function in a network element.

Functional Tests.The K1297-G20 offers flexible protocol configuration mechanisms and a wide selection of programming and scripting tools, which allows test case definition on an abstract level as well as on a detailed protocol level.

Interoperability Tests. In today's telecommunication world, proof of interoperability of services through the different access and core technologies such as GSM, UMTS, SS7, IN, and IP is essential. The K1297-G20 offers an open platform that allows free combination of all supported technologies and protocols in one test scenario. This saves time by creating interoperability test suites or protocol converters involving different protocol families in one test/emulation.

Network Element Emulation. In the early development phase and in the beginning of trial phases, hardware versions of network elements are not always available or affordable. The K1297-G20 can replace missing network functionality by emulating individual interfaces of network elements such as BSS, HLR, or SGSN, or even whole portions of the network such as GGSN and the Internet. With its broad set of pre-developed network element emulations and a flexible configuration, the K1297-G20 substantially shortens time to market/operation in a continuously changing environment.

Monitoring Applications To Verify Performance and Troubleshoot Problems

Powerful, Yet Easy-to-Use Monitoring Tools For:

  • Network Monitoring and Analysis of UMTS, TD-SCDMA, GPRS, GSM900, DCS1800, PCS1900, XoIP, CDMA2000, SS7, and IP
  • Interworking Measurements
  • In-service error detection for GPRS Interfaces
  • Detection of all activities in the core network
  • Verification of protocol implementation (for manufacturers)

Sophisticated filters can be used to reduce the data received to the desired essential results. The K1297-G20 Protocol Tester provides several display formats. Message components are decoded online, interpreted, and issued in mnemonic as well as binary or hexadecimal form. Special search functions enable the targeting of any message components, such as call tracing with a subscriber number or an IMSI/TMSI (international/temporary mobile subscriber identification). Besides the protocol stacks provided, a powerful, graphical protocol stack editor allows users to easily compile the required protocols for each application out of the more than 2600 protocols available.

Measurement Modules

E1/DS1 Interface Board (PRIMO)

The PRIMO VME bus card contains four monitoring only interfaces, configured by the basic software to be DS1 or E1. The interfaces connect to transmission lines via DB9 connectors and matching adapter cables. The PRIMO board allows connection to protected or unprotected monitoring points and the software selects either high-impedance or low-impedance inputs. With six PRIMO modules installed (benchtop model), the K1297-G20 is capable of simultaneously monitoring 24 interfaces with 48 (full duplex) time slots.

E1/DS1 Monitoring/Simulation Boards (PRIME)

PRIME modules are available for two transmission rates, 1.554 Mb/s and 2.048 Mb/s. Four simulation sockets are provided - each containing a transmitter and receiver for PCM signals. For monitoring, a receiver from each of the two adjacent simulation sockets is combined on a single socket.

Each board has the ability to:

  • Simulate on four ports (no monitoring)
  • Simulate on two ports and monitor on one
  • Monitor on two ports

Ethernet Board

Software Tools for the Development of Test Cases/Emulations

The Emulation Scenario Editor (ESE) is the main control center for intrusive test configuration and execution. Its Diagram View offers a very flexible and easy-to-use process to configure the K1297-G20 hardware according to a given protocol stack and test configuration. It also offers Parameter View to configure the individual simulations/emulations and to trigger actions in the software modules. The Test Scenario Control Center (TSCC) configures customized arrangements of parameters for specific applications. Large libraries of sample configurations of standard configurations and test applications are provided for both ESE and TSCC.

The Message Building System (MBS) allows the creation of message templates that will be sent or be compared graphically with received messages. Users are able to select and combine protocol elements to define messages, with the aid of protocol specific information that is presented graphically. The result is a message pool that can be used by the various test case development tools. For interactive testing, as well as for individual error intrusion, messages defined in a message pool can be directly sent via/to a layer emulation. This feature is important in the design and integration of new implementations.

The Message Sequence Chart (MSC) supports the full range of test scenarios from the very simple to the most complex. This development tool defines test sequences in an intuitive and graphic way by placing messages, timers, loops and other elements in a self-documenting message flow chart. The messages are simply selected from a message pool and dragged to the proper position in the flow chart.

FORTH Script Interpreter is a language that supports iterative interactive test script development. Commands are executed instantly as they are typed and they can be combined into complex state machines.

The C Programming Language supports direct programming of complex emulations or test scenarios in a familiar programming language and is commonly used during system integration and test. SDL Development tools may be used as a front end for the C-Programming language to implement emulations in a graphical format.

Software Tools for the Development of Automatic Test Programs

Remote Operation. The Tektronix Remote Operation Package features the Test Synchronization Protocol 1+ (TSP1+) and CORBA (Common Object Request Broker Architecture). It contains primitives and messages to remotely manage a complete test session.

Test Management System for Test Automation. With the Test Management System users can assemble their own test suites for local or remote automated and/or regression testing. The stand-alone graphical user interface can be operated from any Windows PC, and the communication with the K1297-G20 is established via a TCP connection. Change management is provided to fulfill ISO9000 requirements.

PC Development Environment. Physical measurement equipment is capital intensive and frequently in use, so it is important to have a tool that allows you to develop test programs without using the actual test hardware.

The K1297-G20 Offline Development Environment offers:

  • Test case development (MBS, MSC, C, TTCN, FORTH)
  • Test configuration (offline parameter of ESE and TSCC)
  • Playback (decode, filter, monitoring applications) of trace files as if they were live
  • Analysis of test automation log files
  • Use of offline optimization tools
