Main Features

  • GSM Abis Interface simulation over IP.
  • Simulate BSC and BTS nodes.
  • Supports transmission and detection of RTP traffic – Auto Traffic digits, file, tones, fax, user-defined traffic,

and IVR.

  • Supported codec types include G.711, G.729, G.726, GSM, AMR, EVRC, SMV, iLBC, SPEEX, G.722, and
  • more. *AMR, EVRC variants requires additional licenses.
  • User-friendly GUI for configuring the TCP Layer.
  • Configure AGCH, ACCH, SDCCH, BCCH and other logical channels.
  • Supports Location Update Call, Mobile Originated Voice Call, Emergency Call, Mobile Originated SMS,

Mobile Terminated Voice Call, and Mobile Terminated SMS procedures.

  • Access to all BTSM Message Parameters like TMSI, IMSI, CIC, MCC, LAC, and others.
  • User controlled access to optional parameters such as timers.
  • Supports Authentication, TMSI Reallocation, Encryption and other optional procedures.

Applications

  • Setup a virtual real-time network simulating 2G-GSM GPRS network elements using ‘MAPS™ 2G

Wireless Lab Suite’

  • Multi-protocol, Multi-interface Simulation
  • Provides fault insertion, and erroneous call flows testing capability
  • Performance testing, Load Testing, Functional testing, Regression testing and Conformance testing of

network elements

  • Ready scripts makes testing procedure simpler, less time consuming and hence time to market

products.

  • Test response of network against protocol message modification, or corruption
  • Inter-operability testing of networks
  • Wrap-around testing (WAT)
  • SMS Testing from within the Wireless Infrastructure using MAPS™

SMS Procedure

  • SMS (Short Message Service ) uses signaling

channel as opposed to dedicated channels, hence these messages can be sent/received simultaneously with the voice/data/fax service

  • ver a GSM network.
  • SMS supports national and international

roaming, meaning SMS can be sent to any

  • ther GSM mobile around the world.
  • Each short message can be no longer than

160 characters. These characters can be text

  • r binary Non-Text Short messages.

MAPS™ API Architecture

MAPS Feature

  • API wraps our proprietary scripting language in standard languages familiar to the user:

➢

Python

➢

Java

➢

VB Scripts

➢

TCL

  • Clients and Servers support a “Many-to-Many” relationship, making it very easy for users to develop

complex test cases involving multiple signaling protocols.
