Call Generation and Control

Emulate call signals and traffic using scripts. Commands in the scripts are executed in controlled way to emulate protocol and traffic behavior. Most of the commands used in the scripts are generic and independent of specific protocol.

MAPS™ application acts as either the Caller or resides at the network terminal acting as Callee. The Call Generation feature emulates an outgoing call by sending call control messages to the DUT using scripts and profiles. The profiles allow necessary parameters of call control messages to be changed during runtime. Call generated from other entity can be automatically detected in call reception window by pre-setting the required answer scripts in the Incoming Call Handler.

Message Sequence - Each call scenario provides the trace with full decoding of the messages exchanged between the MAPS™ and the DUT, and graphical ladder diagrams of the call flow with time stamps. Impairments can be applied to messages to emulate real world networks.

Event-Driven Control - Scripts execution, being event-based, allows redirection of script execution on-the-go with user-defined events. The custom parameters in the events can also be changed during script execution using event profiles.

Script Contents & Script Flow - The script flow and the contents window display the Script Name, Sub-script Name, Script line number, and script statements to be successfully executed, which help the users in troubleshooting a particular call scenario.

Traffic Emulation

The call control scripts can also automatically handle the traffic over the established call. MAPS™ supports transmission and detection of various traffic types over  IP (RTP, GTP), ATM, & TDM over established calls with the support of necessary hardware. The types of traffic supported are -

  • Analog and TDM Traffic (digits, voice files, single tones, dual tones, Dynamic VF, fax, sms, and IVR)
  • RTP Traffic (digits, voice files, single / dual tones, fax, video, and IVR)
  • Mobile Traffic (User-plane GTP and Gateway – SMS, HTTP, Email, FTP, Video)
  • Short Message Service (SMS) Test Solutions.

For more information, visit Traffic Emulation webpage

MAPS™ also includes support for wide range of codec rates – visit Voice-Codecs webpage for more details. 

Bulk Call Generation and Load Testing

MAPS™ supports automated stress/load testing capabilities through Load Generation and Bulk Call Generation features. Bulk Call Generation allows quick configurations to easily create multiple test entries with different scripts and profiles. Multiple tests can be run simultaneously or sequentially (queue up tasks in succession). Load generation feature further allows specifying the patterns with which the bulk calls can be generated. Load generation can be customized with different statistical distribution patterns such as Uniform, Ramp, Sawtooth, Fixed, Normal, Step, and Step-Sawtooth distribution. Load Generation supports Unique and Multi Distribution patterns. Unique Distribution pattern option allows to configure single distribution pattern for each loaded script, whereas with Multi Distribution pattern, multiple patterns can be configured for each loaded script. Call duration also can be randomized using similar statistical distribution. This feature also helps users configure Stress/Load Testing parameters such as Call per second (CPS), Max Active Call, Minimum and Maximum Call Rates, Start Call Rates, and other parameters.

To perform Bulk Call Generation, several UE/Subscriber configuration files are required. The UE/Subscriber configuration files can be created using regular Profile Editors (XML Based), using CSV based profiles, or using Auto Generation feature. With CSV based profiles,  it is possible to define up to 20,000 subscriber entries with unique called number, calling number, and other subscriber specific information. . With Auto Generate Users feature, MAPS™ can dynamically generate any required number of users while assigning unique IMSI for each generated user in sequential order.

Scheduler

Emulate bulk calls at a specific start time. The pre-saved configuration files for test setup and call emulation are automatically loaded to automate the test procedure.

Customization of Test Setup Parameters

The test setup profiles (.xml files) allow users to configure the necessary parameters in order to establish communication between MAPS™ and the DUT. It includes configuring parameters of the network nodes, the network properties, and transport related configurations such as SCTP or TCP IP Address and port numbers for both MAPS™ and the DUT.

Once the transport layer is configured properly, protocol specific signaling messages and traffic can be transmitted and received successfully. All parameters setup in test setup are global and are accessible to all scripts. These parameters initialize protocol engines and the transport modules specific to the protocol.

Customization of Test Parameters, Call Flow, and Protocol Messages Using Pre-Processing Tools

  • Message Editor - The Message Templates (GL’s proprietary *.HDL files) comprises of protocol encoding parameters with preset values. It is required to create a message template for every message in a protocol. The message templates are called within the scripts to perform scenario-based testing.

  • Profile Editor – Profiles (*.xml files) are used to change the values of the fields in the messages (i.e. Message Template in MAPS™) during the course of a call. The multiple profiles with varying parameter values that allow users to configure call instances in call generation and to receive calls. Color coding feature to create multiple profiles, which are used to sort and group all calls associated to individual nodes during Call Reception.

  • Script Editor - The script editor allows the user to create / edit scripts and to define variables for the fields in the messages. The script uses pre-defined message templates to build call flow and perform send and receive actions. Script editor provides options to run the test for multiple iterations in sequential or random flow. Commands allow retransmission of messages with specific interval.

Command Line Interface

Supports scripting through a Command Line Interface (CLI), using Python with MAPS™ client-server functionality (requires additional license)

MAPS™ can be configured as server-side application, to enable remote controlling of the application through multiple command-line based clients.

User can remotely perform all functions such as start test bed setup, load scripts and profiles, apply user events such as send digits/file/tones, detect digits/file/tones, dial, originate call, terminate call, start and stop traffic and so on. User can also generate and receive calls through commands. This client application is distributed along with MAPS™ Server application. Multiple MAPS™ CLI servers can be controlled remotely from single client application.

Call Statistics, Events, Link Status, User Defined Statistics

Call Status & Message Statistics - By default, all call handling scripts (irrespective of the type of the functions) are assessed by MAPS™ to provide statistical information about Total Calls, Active Calls, Completed Calls, Passed Calls, Failed Calls, and Calls/Sec. It is also possible to categorize the statistical information as per the call handling scripts. In addition, Call Generation and Call Reception windows provide useful call status & script execution results.

In addition, Message Stats option for any specific protocol, logs number of times the messages are being transmitted (Tx Count) and received (Rx Count), thus allowing user to monitor the occurring events.

User Defined Statistics and Graphs – Users can customize the global statistics for RTP audio and video traffic. These global parameters are defined in the call generation scripts, which are calculated and updated periodically providing call quality metrics such as Listening MOS, Conversational MOS, PacketLoss, Discarded Packets, Out of Sequence Packets, Duplicate Packets, Delay and Jitter. User can also customize scripts to create various types of graphs such as Pie graph, Line graph, Multi-Line graph, Bar graph, and Point graph to plot RTP statistical information.

Events Reporting – MAPS™ provides Event Log, Error Events, and Captured Errors windows that log the captured events and errors encountered during the progress of the call.

Link Status - Link Status window indicates transport related information of the protocol, for example, if SCTP is used as transport, it indicates if the association is Up or Down in the Link Status window.

Working Principle of MAPS™ Application

Call Control (Call Generation and Reception)

  • Protocol Engine
    Forms the backbone of MAPS™ application that contains Message Templates, and Call Handlers to help MAPS™ encode and decode protocol messages, exchange user-defined protocol field values at run time, and generate call flows.

  • Transport Handlers
    Support send & receive protocol messages over various transport layers - UDP,   TCP, SCTP, LAPD, MTP2, and ATM.

  • Global Configurations
    Handles parameter configurations that are common across different test scenarios, such as protocol timers, inter-call duration, and so on.

  • Impairment and Retransmission Modules
    These modules support unexpected call behaviors to test system performance under realistic network conditions. These include – tests to introducing impairments at the traffic level or at the communication protocol level, retransmission of messages at defined interval of time, and so on .
  • Traffic Handlers
    These modules support generating and received traffic from the other network entities using different traffic type – Traffic over TDM / Analog, over IP, and encapsulation of IP traffic over GTP (Mobile Gateway / Packet Traffic)

Pre-processing Tools

Script Editor

  • Allows users to build valid and invalid test cases
  • Includes ready-to-run scripts for simulating important call scenarios / procedures.
  • Offers ‘syntax-ready commands’ to easily build scripts
  • Reusability, easy maintainability and reduced ‘time-to-market’.

Message Editor

  • Allows users to modify any signaling message, message parameters, and/or information elements.
  • Add, modify or remove any optional parameters depending on specific feature of interest.
  • Perform packet level fault insertion by impairing any bit / byte of a message.

Profile Editor

CLI/API

MAPS™ CLI clients server in network

MAPS™ can be configured as server-side application, to enable remote controlling through multiple command-line based clients. Supported clients include Python and Java. Python is supported over all protocols as a standard and Java over limited protocols.

The MAPS™ APIs allows for programmatic and automated control over all MAPS™ platforms. Each MAPS™ server can receive multiple client connections and offer independent execution to each client. Likewise, a single client can connect to multiple MAPS™ servers, including servers running different protocols, permitting complex cross-protocol test cases.

Client provides a simple scripting language, with programming facilities such as looping, procedures, and variables. The Client application includes a MapsClientIfc.dll file, a packaged library that enables communication with the Server from the client environment. The advantage of such communication enables user to control MAPS™ by sending commands and receiving responses in a scripting language already familiar with many users.

Clients can remotely perform all functions such as start testbed setup, load scripts, and profiles, apply user events such as send digits/file/tones, detect digits/file/tones, dial, originate call, terminate call, start and stop traffic and so on. User can also generate and receive calls through commands. This client application is distributed along with MAPS™ Server application.

The following depicts MAPS™ Python Client Interface used to place call and handle traffic between the end terminals. Also, observe the executed commands in the MAPS™ CLI Server window after completing the call.

Traffic Simulation across IP, Analog, TDM, and Wireless Networks with MAPS™

As traffic volume increases, network infrastructure can be subject to various impairments such as errors, excessive delay, congestion, blocking, loss, and degraded quality. Simulating traffic is valuable to characterize the impairment as a function of traffic volume and type (e.g. voice, fax, data, & video).

Message Automation and Protocol Simulation (MAPS™) is a multi-protocol, multi-technology platform used to generate call signals and traffic for diverse communication protocols covering IP, analog, TDM, and wireless networks. MAPS™ can be used to test legacy networks (CAS, SS7, ISDN, PPP, etc.), newer generation IP networks (SIP, MGCP, MEGACO, SIGTRAN, Diameter, etc.), and also wireless networks (GSM, UMTS, LTE and Diameter signaling).

MAPS™ Client-Server application includes a command line interface with support for Python, Java, TCL and other scripting tools to provide remote operation, automation, and multi-site connectivity. The user can remotely perform all functions such as load scripts and profiles, send digits/file/tones, detect digits/file/tones, dial, originate calls, terminate calls, start and stop traffic and so on.

What is the difference between 32-bit and 64-bit versions of MAPS™ Application?
Basically both 32-bit and 64-bit Implementations of MAPS™ work exactly similar. MAPS™ 64-bit compilations have significant performance advantages over 32-bit, if only signaling is considered (without traffic) by making use of Large amount of RAM (Random Access Memory ) available on the 64-bit machine. Currently only IP based MAPS™ have 64-bit versions.

Can I run 32-bit MAPS™ on a 64-bit computer?
MAPS™ 32-bit versions will work on 64-bit machines. But is is adviced to use 64-bit   versions when high performance is desired.

Can I run 64-bit MAPS™ on a 32-bit computer?
MAPS™ 64-bit application is designed for the 64-bit version of Windows® will not work on the 32-bit version.

MAPS™ is not invoking, throwing load MAPS™ dll error. How to resolve?
This error occurs when installation is not proper or certain steps in installation are skipped. Please install the software again with run as administrator and do not cancel winpcap installation which is essential for MAPS™ application.

I am getting Error “Security Error: Application is not licensed”, what should I do?
If you see this error when you run MAPS™ application it indicates a problem with either   your dongle or license file.
  • First verify that the dongle is plugged in and the red light is on
  • Navigate to C:\Program Files\GL Communications Inc\GLDONGLE
  • Run haspinfohl.exe. Verify that Status is OK and make a note of the Serial #.
  • Run appl_list.exe. Verify that there is a line in the table reading PKSXXX MAPS™ Application with the serial number you noted above.

If the dongle does not appear in haspinfohl.exe, verify that it appears as a USB device in the Windows Device Manager. If it does not appear even in the device manager,   remove the dongle and plug it into a different USB port, preferably one directly on the motherboard.

I am getting 192.168.56.63: 3566 : please verify IP/Port not in use Unable Create Sctp Socket Error. What could be wrong?
Check if you are using an invalid ip address or port number which is either invalid or in use by any other application. Try to change the IP address and Port number which should resolve the issue.

Error: Unable to connect to MAPS when it uses TCP as transport & configured as Server ?
- Please verify if you have configured proper IP address & port number.

- Please verify if any Firewall or Anti-virus software is installed on your computer which might be blocking incoming TCP connections.

The easiest way to verify if the incoming TCP connection actually reaches the Windows TCP/IP stack. Please use any web browser and access with http://IPAddress:port. For example if MAPS is installed on IP 192.168.1.1 then use http://192.168.1.1:8045. Here port number must be unused/free. So use port numbers which are not used by any applications. Capture the TCP traffic with GL's PacketScan™ or Wireshark to see if you see any response for TCP SYNC packet. If you see no response & SYNC packet is retransmitted, then most likely your firewall or antivirus is blocking any incoming TCP connection request.
Error: “Unable to create GLIpHandler:Invalid Arguments”

If you see this error when you start the testbed from MAPS™ application, it indicates that the Network Adaptor is not configured correctly.

From Help menu -> run Display Adaptor Info and obtain the Adapter Index for the IP address in use, which has to be appropriately configured in the Testbed.

Error: Unable to Connect to WCS. Start GL Server.

This error is related to MAPS™ Applications which simulate traffic with GL's WCS servers such as TDM traffic, and mobile IP Core.

If you see this error follow the steps below -

  • Verify if the MobileIpCore basic server is installed on the PC and also verify if the ETH101 licenses are installed.
  • In T1 E1 check if the server is invoked and started.

SCTP Connection is NOT established. How to Resolve?

SCTP Connection problem may be related to various reasons.
  • Run the MAPS™ application as ADMINISTRATOR
  • Turn OFF Windows Firewall
  • Check if the SCTP Mode is proper / whether Device under test is acting as Server /Client. Configure the MAPS™ application accordingly.
  • Check if the proper IP addresses and Port numbers are configured
  • Check if the  Adapter index is configured properly by verifying the adapter information under help
  • Check for ICMP Packets with Protocol Unreachable Information in WireShark®/PacketScan™ applications. If so, assign a free IP address to MAPS™ application instead of system IP Address

If the problem still persists please contact GL for support at info@gl.com



MAPS™ is NOT responding to any incoming messages
Check the Link Status of the SCTP/TCP Link. If the link status is not UP, stop the Testbed, verify the parameters configured in the Testbed and restart the testbed.

Open Events from Reports menu and check if any of the following Errors are logged in the Captured Errors tab.

  • No Valid Script Assigned for "MESSAGE TYPE"
  • Check the Incoming Handler Configuration whether any script is configured for the Message type, If not set the appropriate script against the required message type.

Parsing Error or Script not accessible error: If this error is logged in Captured Errors tab, check if the configured script is present in \Scripts folder in the installation directory. If the script is present, check if the script has any parsing errors with the help of Script Editor.

Decode Error: If Decode Error is observed in Captured Errors tab, it indicates that the message received is not understood by MAPS™.

Stop MAPS™ application. Create ‘Debug’ folder in \MAPS™ working folder where you can find Scripts and Message Folder. Invoke the MAPS™ application and start the Testbed. Check if any log is created under debug folder when Decode Error is received. Send the ErrorLog to GL technical support person. If you do not know your technical support contact, please reach us at info@gl.com.

Can MAPS™ be executed remotely?
Yes. MAPS™ recently introduced a client/server option. This option will allow a client (located on Windows® 7/8) to control a single MAPS™ or many MAPS™ applications over a LAN, WAN, or Internet. The client will incorporate a DLL  that can be used for development of a user GUI.

Can MAPS™ impair or corrupt outgoing messages?

We can corrupt any outgoing message by applying impairments. Impairment implementation is based on low level bit manipulation. User can specify the offset from the beginning of the frame & do various bit level operation to achieve impairment. At this level we are just playing with Hex Values & cannot give protocol field names

Impairments are applied with the send function only – crc is still correct. Impairments are applied on Message portion which MAPS™ simulates. For example in ISUP-Sigtran only M3UA and ISUP layers are simulated using MAPS, and the message over these layers can be impaired. MAC/IP/SCTP layers are emulated using real protocol stacks so you cannot impair these layer contents. Same is applicable to MTP & HDLC (CRC) which cannot be impaired.
Calculating the offset then the XOR pattern is a bit tedious –can it be made simpler? Message Editor displays the exact offset which can be used directly similar to protocol analyzer.
