Through lectures and case studies the course participants will gain detailed knowledge in GSM/ UMTS Signaling in the Core Network, all signaling flows, method of analyzing traces, and gain confidence in troubleshooting.

Course Outline
After participating in the course, you will be able to:

• Design or improve MTP-3 based routing in an SS7 network and global ttle based routing
• Implement effective routings in SS7 MTP3 level and in SCCP-GT level
• Perform new routines in operations & maintenance which includes ability to analyze SS7 traces, SIGTRAN traces and GSM-MAP traces, to
   help improve the time in resolving network issues.
• Troubleshoot an end-to-end signaling in GSM network switching sub-system as well as Session Initiation Protocol (SIP) related signaling
• Integrate the components in WCDMA core network having understood the evolution of WCDMA core network as well as its interfaces
   and protocols (Release 4)
• Analyze SS7-ISUP traces, its routing related to GSM/ UMTS and signaling transport SIGTRAN traces
• Build expertise in Mobile Application Part Protocol (MAP)
• Apply the fundamentals of Stream Control Transmission Protocol (SCTP)

Description Telecommunications engineers need a clear understanding of the signaling details that evolved in the Network Switching Subsystem (NSS) of GSM/UMTS with relation to SS7, including the layers such as MTP3, SCCP layer, and MAP layer. The participants will become familiar with ISUP protocol inter-working with GSM MAP protocols over traditional TDM (T1) and IP (SIGTRAN). They need analysis of signaling flows, and debugging and troubleshooting of GSM/UMTS Signaling so that they can make practical usage of SS7 in GSM/ UMTS. Through lectures and case studies the course participants will gain detailed knowledge in GSM/ UMTS Signaling in the Core Network, all signaling flows, method of analyzing traces, and gain confidence in troubleshooting.

Objective To provide participants the details of the Network Switching Subsystem of GSM/ UMTS in relation to SS7.

Who Should Attend?

Engineers and managers responsible for the implementation, integration, planning, operations, maintenance and support of the GSM NSS/ UMTS network

The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
