17 PRMT Confidential Proprietary 16 Understanding AP-6000s operation and basic features

18 PRMT Confidential Proprietary 17 The AP-6000 has three main steps in its operation: –Configuration –Real Time Capture –Off-line Analysis

19 PRMT Confidential Proprietary 18 –Configuration Allows to set up parameters on how the AP is going to work Band & Frequency Auto or Manual modes Which UE to follow

20 PRMT Confidential Proprietary 19 –Real Time Capture Trace a particular UE following RRC messages –Off-line Analysis The console software provides several ways to display signaling information as well as control and user plane data Allows to export data such as SIB, TPC at frame and time slot level, U-plane data

21 PRMT Confidential Proprietary 20 The first step is to create a SCENE and configure basic parameters The SCENE will contain all the calls we record A file is created with each SCENE and the calls are automatically saved Auto or Manual Mode Band and DL Frequency # of cells to be detected (idle mode)

22 PRMT Confidential Proprietary 21 Once the Band and Frequency have been set, the SCH can be detected SCH Profile * Node Bs detected with: SCH strength in dBm * Primary SCR Code * * The information displayed here is from a simulation.

23 PRMT Confidential Proprietary 22 Configure if the call is going to be carried out in one or two frequencies (Inter-Freq HO) In the case of Inter-Freq HO, AP only needs to know the first DL Freq. Changes in Freq are followed according to InterFreqMeasurmentInfo, or RRC messages containing info on the second Freq. Single or Multiple Freq

24 PRMT Confidential Proprietary 23 There are three ways to trace a UE –First FACH –First RACH –Specify a UE ID by its IMSI, TIMSI, P-TIMSI or IMEI The console SW allows to store the 16 most used UEs Way to trace a UE

25 PRMT Confidential Proprietary 24 AP has built in the KASUMI algorithm used for encryption in UMTS In order to properly decode all messages the AP needs to know the CK used by the UE Four options: –Enter the CK values –Use a Test USIM and enter the K value –Use the RS-232 port in the Console PC to enter the CK values from the UE as they change during the call. This required a special modified UE with access to CK values –USIM reader Ciphering Options

26 PRMT Confidential Proprietary 25 Fifth option –Using a UE that does not support ciphering Note: If CKs are unknown it is possible to decode the common channels but not the dedicated channels Ciphering Options

27 PRMT Confidential Proprietary 26 Start recording a call –Once the configuration is done, it is time to record a call Recording a call is known as a TAKE There can be many TAKES in on SCENE file Each individual TAKE can be saved without the need of keeping the original SCENE file Start a Take
