What do you know about GSM architecture and the interface of connectivity, OSI Model and layers (function of each layer) ?

Question

Accepted Answer

GSM architecture includes multiple layers of OSI model for connectivity. Each layer has a specific function.

GSM architecture consists of physical, data link, network, transport, and application layers.
Physical layer handles the transmission of bits over the air interface.
Data link layer provides error-free transmission of data frames.
Network layer handles routing and addressing of data packets.
Transport layer ensures reliable end-to-end data transfer.
Application layer provides services to end-users.
OSI model layers include physical, data link, network, transport, session, presentation, and application layers.
Each layer has a specific function and communicates with adjacent layers.
For example, the physical layer handles the transmission of bits, while the data link layer provides error-free transmission of data frames.
Understanding the GSM architecture and OSI model is crucial for NOC engineers to troubleshoot network issues.
