The Number Portability for GSM (G-Port) course provides students with an overview of the G-Port network architecture, GSM network components and terminology. This course identifies the purpose and function of the G-Port feature, while going through call flows for the number portability and mobile number portability environments.

Learn To:

  • Describe how Message Signaling Units (MSUs) are affected by the G-Port feature.
  • Describe how the MSISDN is extracted from the MSU.
  • Describe how the MSISDN is conditioned for Real Time Database (RTDB) lookup.
  • Describe how the SRI (Send Routing Information) response is sent to its destination.

Benefits to You

Learn about EAGLE and EPAP implementation and activation steps supporting the G-PORT feature. For reporting and troubleshooting purposes, the student will learn how to retrieve measurements for the activated G-Port service.

This course also contains optional lessons that include, but are not limited to, routing procedures such as G-Port Circular Route Prevention, G-Port SCCP Service Re-Routing, GSM MAP SRI Redirect to serving HLR, Intra Network Number Portability, G-Port for SRI Query for Prepaid, GSM SMS/MMS NP, Service Portability and optional Digit Action Features.
