The present document describes the technical characteristics and methods of test for Mobile Stations (MSs) within the digital cellular telecommunications system. The graphical form ATS The electronic form of the graphical representation (TTCN.GR format) corresponding to the ATS for Layer 3, is contained in the Adobe Portable Document Format™ file IR_XXX.pdf where XXX corresponds to the current version. The machine processable ATS The electronic form of the machine processable file (TTCN.MP format) corresponding to the ATS for Layer 3, is contained in the file IR_XXX.mp where XXX corresponds to the current version. The present document is part 5 of a multi-part 3GPP TS covering the digital cellular telecommunications system; Mobile Station (MS) conformance specification, as identified below:

The present document specifies the Abstract Test Suites (ATS) and partial IXIT proforma for the Network Layer (Layer 3) at the mobile radio interface of the GSM/3GPP mobile stations (MS) conforming to the TSs for Layer 3, for the digital cellular telecommunications systems. The present document is valid for MS implemented according to R99, 3GPP Release 4, Release 5, Release 6, Release 7, Release 8, Release 9 or Release 10. The ISO standards for the methodology of conformance testing and the TTCN language are used as the basis for the test specifications.
