To provide user with detailed Handover information handover causes statistics handover per couple of cells Advantages of A-Interface Analysis Tool Measurements are performed on Standard A-Interface Independent of manufacturer system implementation and measurement facilities BSS as well as NSS from different manufacturers can be analyzed  Portable and autonomous tool all accurate QoS statistics are available no deep knowledge of BSS system and management are required to use it Input File acquisition and description (1) Example: Acquisition with K1103 protocol analyzer Input File acquisition and description (2) AGLAE tool relies on SCCP Connections references to follow a call. As SCCP messages can be sent on any of the N7 links of a BSS (load sharing), all N7 links of a BSS have to be monitored simultaneously. Message decoding based upon GSM Rec 08.08 and 04.08 MTP (Layer 2) SCCP (Layer 3) BSSAP DTAP input for AGLAE is .REC -binary file- AGLAE package and requirements AGLAE package runs on a PC in Windows environment 80386DX 33Mhz processor (speed of analysis) 4MBytes RAM DOS Vrs 5.0 or later processing can be performed on K1103 itself Package Content AGLAE.EXE runtime module AGLAE.DLL AGLAE.USF contains defaults statistics formulas AGLAE.OPT contains default options for execution All output files are spreadsheet formatted files (or Excel for
