Introduction to Major GSM Services

 

Over the past 20 years, GSM has gone from providing basic 2G voice services only to a wide variety of data services and value-added services. GSM growth has stimulated a growing demand for improved user experience. As networks grow complex, operators value high quality voice services, high PS carrier efficiency, high spectrum usage efficiency, and energy savings, more than ever. Huawei provides GSM solutions:

 

If you are planning a network, you might ask: What features does GSM have? Which features are included when just starting? Which ones are added during O&M?

If you are maintaining a network, you might ask: How do I enable a particular feature? If a feature is not performing as expected, how can I improve it? If a feature malfunctions, how do I fix it?

The answers to these questions can be found in the GBSS Feature Documentation.
