GL Conveys the Availability of its GSM Analysis and Simulation Software

GL Communications conveyed the availability of its GSM Analysis and Simulation software.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, ” GL's GSM Analyzer is used to analyze GSM protocols, a switching and signaling telecommunication protocol between MSC & BSC, BSC & BTS, MSC & SMLC, UMA & MS,. and so on. GSM analyzer also supports decoding proprietary 'Mobis' Interface (Motorola equivalent of the GSM A-bis interface) with additional license XX151 between BSC (Base Station Controller) - BTS (Base Transceiver Station) and BSC (Base Station Controller) - PCU (Packet Controller Unit).”

He added, “Other interfaces supported include Ls / Lb / Lp Interface (Interface between MSC and SMLC), and Up (Interface between UNC (UMA network controller) and MS). HDLC frames are parsed according to Q.921, SS7 information parsing is based on ANSI and ITU standards: T1.111, T1.112, T1.113, Q.703, Q.704, Q.708, Q.723, Q.763 & GSM information parsing is based on 3GPP TS 08.08¸ 3GPP TS 24.008, 03.40, 3GPP TS 04.11, 3GPP TS 08.58, 3GPP TS 04.18. MTP2 is parsed according to ANSI-ITU standards and the higher GSM layer information parsing depends on the user's selection of GSM 900, DCS 1800 & PCS 1900 according GSM variants.”

Mr. Vadalia further added, “GSM applications are supported that further help in emulating GSM protocol over A & Abis interfaces. GL's GSM A Interface Emulator is an advanced protocol simulator/tester for GSM simulation over A Interface that can simulate network elements MSC and BSC by generating and receiving BSSMAP and DTAP messages. The signaling specification conforms to ITU-T and 3GPP standards.

GL's GSM Abis Interface Emulator is an advanced protocol simulator/tester for GSM simulation over Abis Interface that can simulate network elements BTS and BSC by generating and receiving BTSM messages. The signaling specification conforms to 3GPP standards.”

Some of the Important Features Of GSM Analyzer

·Interfaces supported are A (Interface b/w BSC and MSC), A-bis (Interface b/w BSC and BTS), Mobis (Motorola Proprietary Interface b/w BSC and BTS and also b/w BSC and PCU), Gs (Interface between SGSN and MSC), Ls / Lb / Lp Interface (Interface between MSC and SMLC), Up (Interface between UNC (UMA network controller) and MS).

·Decoding of many RR layer non-transparent messages such as "System Information", "Measurement Result", "Immediate Assignment" etc. ·Search and filtering capabilities. ·Exports Summary View information to a comma delimited file for subsequent import into a database or spreadsheet. ·Capability to export detailed decode information to an ASCII file. ·Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields. ·Remote monitoring capability using GL's Network Surveillance System.
