SIGTRAN Protocol Testing and Emulation Solution

GL's multi-protocol emulation test suite Message Automation and Protocol Simulation (MAPS™) SIGTRAN is an advanced protocol emulator designed for emulating SS7 over IP Networks. It can replicate the ISUP signaling specifications as defined by ITU-T standards. This application is versatile, supporting a range of testing scenarios such as network element testing, error tracking, regression testing, load testing/call generation, and the generation of high volumes of ISUP traffic.

MAPS™ SIGTRAN functionality encompasses both ITU and ANSI variants of ISUP, over M3UA, M2UA and M2PA transports. It can execute pre-defined test scenarios against ISUP test objects in a controlled and deterministic manner. Combining MAPS™ SIGTRAN Emulator and MAPS™ SS7 Emulator creates a unified entity capable of emulating a complete Signaling Gateway.

MAPS™ SIGTRAN ISDN over IP is an advanced protocol emulator designed for emulating ISDN signaling over IP. This tester can emulate a comprehensive ISDN connection between SG and MGC, following the ISDN signaling specifications outlined by ITU-T Q.921/Q.931 standards. It serves as a robust tool for detailed testing of ISDN protocol messages over IP, providing a comprehensive solution for testing, troubleshooting, and maintaining devices and networks implementing PRI ISDN.

The Bearer Independent Call Control protocol (BICC) is a call control protocol based on ISUP and is employed between serving nodes to facilitate ISDN services irrespective of bearer and signaling transport technology. The MAPS™ BICC IP Emulator is utilized to emulate all BICC interfaces over IP. It is specifically designed to emulate BICC call control signaling, as defined by ITU-T standards, between Mobile Switching Center (MSC) and Gateway MSC (GMSC) server nodes.

The Mobile Application Part (MAP) is a GSM protocol which provides application layer services to the various nodes in GSM and UMTS networks. MAP can be transported using 'traditional' SS7 protocols carried by Message Transfer Protocol (MTP) by M2PA, M3UA, and M2UA User Adaption layer in IP using SIGTRAN.

MAPS™ MAP emulator can be configured as MSC/VLR, RNC, HLR, EIR, SMSC, SGSN, GMLC and GGSN entities to emulate C, D, E, F interfaces in the GSM network and Gc, Gd, Gf, and Gr in the UMTS network. It has a user-friendly GUI for configuring the MAP signaling links over IP and TDM. Access to all M2PA, M2UA, MTP3, M3UA, SCCP, and MAP R4 protocol fields such as TMSI, IMSI, MCC, MNC, MSIN, CCBS and more.

MAPS™ INAP (Intelligent Network Application Part) over IP services support testing network elements such as gsmSCF and gsmSSF, error tracking, regression testing, conformance testing, and load testing/call generation. It is capable of running pre-defined test scenarios against INAP test objects in a controlled and deterministic manner.

MAPS™ CAMEL IP Emulator can emulate CAP supplementary services like unified messaging, prepaid, and toll-free (Freephone) in GSM, GPRS, and UMTS over IP networks. CAP information flow is defined between functional entities such as Service Control Function (SCF) and Service Switching Function (SSF) distributed across the network to execute services. MAPS™ CAMEL IP Emulator can be configured as SCF and SSF entities in GSM, GPRS, and UMTS networks to emulate CAMEL services.
