B.1 Difference between Messages on the A Interface in Different Phases

The GSM technical specification is a standard constantly improved and perfected. With the introduction of Phase1, Phase2 and Phase2+, GSM provides different new services for user to satisfy the requirements from the market. Phase1 of the GSM technical specification includes 3.x.x series standard; Phase2 includes 4.x.x series standard, and the subsequent series standards 5.x.x, 6.x.x and 7.x.x belong to Phase2+. This technical specification provides good compatibility in the development.

This section gives the development of the A-interface L3 protocol (GSM 08.08) in each phase. To facilitate description, take the typical protocol in each phase for analysis: GSM08.08 version 3.10.1 is for Phase1, GSM08.08 version 4.7.1 for Phase2, and GSM08.08 version 7.6.1 for Phase2+.

B.2 Difference Analysis
