A combination of monitoring, simulation,and emulation functions, as well as capability of conformance and interoperabilitytesting is provided, chiefly needed during design and installation/deploymentof GPRS networks. This also includes monitoring and analysis functionsneeded during field trials, operation and maintenance, and network optimization. GPRS reference model. Solutions for Network Monitoring and Optimization Monitoring GPRS network managers struggle with the difficult problems of networkinstallation, deployment, and optimization. GPRS software for the K1297consists of all necessary GPRS features and applications that help usersovercome their most difficult network issues. They can be carried outin off-line mode and online mode. Single Interface and Multi Interface Call and Transaction Traces Single Interface Call and Transaction Traces allow a fast overview aboutall data and messages related to a call/transaction. This offers fastand easy analysis of subscriber-related problems. The 揗ulti Interface Call Trace?application is an expert software thatpermits tracing calls/sessions in real-time and off-line as they evolveover multiple interfaces. Simple parameters are used to identify the subscriber (for example, IMSI)and to trigger the search. The call/session is traced even if parametersidentifying the subscriber change dynamically during the transactions(such as IMSI, P-TMSI). The call/session is traced even if it spans multipleinterfaces (for example Gb, Gr, Gn) and involves different network elements(for example SGSN, HLR, GGSN). Call Trace User Interface. The GUI allows drill-down troubleshooting from the problem symptom tothe root cause with just a mouse-click. The 揙verview Window?lists detected calls/sessions and highlights theirstatus (normal, failed) at a glance for quick problem identification,and allows filtering out uninteresting (normal) calls. The 揂rrow Diagram?graphically displays, in a very intuitive way, themessage flow (arrows) and network elements (vertical lines) involved ina call/session without requiring a deep protocol knowledge. The 揇etailed Monitor Window?shows all the details of protocol messagesand parameters for in-depth troubleshooting of root cause of problems. Multi Interface Call and Transaction Trace Application. Deciphering GPRS network operators transmit ciphered data between GPRS terminalsand the network more often then they previously have. Whenever encipheringis switched on in GPRS networks, all signaling data and payload abovethe protocol layer Logical Link Control (LLC) are encrypted. K1297-G20Protocol Testers supply the first deciphering test and observation tools,enabling analysis and processing of all data above the protocol layerLLC. Deciphering solution - enciphered messages. Deciphering solution - deciphered messages. The GPRS Deciphering application decrypts Control- and User Plane messageson the Gb-Interface not only for GPRS but also for UMTS mobiles (e.g.after an Intersystem Change for PS-Services from UTRAN to GSM BSS). Itsupports the GPRS Encryption Algorithm-1 and -2 (GEA 1 and GEA-2). Inautomatic mode the application collects ciphering keys (Kc or CK) fromthe Gr-Interface (see picture below). In manual mode no access to theGr-Interface is required. This is a special use case for test labs, wherethe user can manipulate the ciphering key. Ciphering Key collection on the Gr Interface. RLC/MAC Reassembling The RLC/MAC reassembling application picks up frames at the GPRS Abisinterface that are cut into slices of different sizes depending on thecoding scheme and assembles them to the original frame. This comprisesLLC frames and RLC control frames. Benefits of RLC/Mac Monitoring on the Abis-Interface: Verification of PCU transportation layer implementation (NEMonly). Verification/Observation of Air Interface parameter (e.g. Powerlevel, Receiver sensitivity). Analysis of faulty behavior related to the Air Interface (e.g.Retransmissions). Compliance verification of Mobiles and Network (Interoperability). Automatic Configuration of Abis GPRS/EDGE interface (Siemens) The GPRS/EDGE Automatic Configuration is an application that guides thetechnicians in configuring the instrument for Abis monitoringand allows them to reduce overhead time needed for instrument set-up.Once the RSL link on the Abis interface has been identified,the application automatically configures all the necessary logical linkscontaining USER DATA FRAMEs and assigns the proper bandwidth to the logicallinks. GPRS Gb Monitor/Analyzer The GPRS Gb Monitor application provides an extensive overviewon the traffic that is actually running on the Gb-interfaceof a GPRS network. Numerous filter possibilities, including cell ID, IMEI,IMSI, and IP addresses, are available; measuring Quality of Service (QoS)parameters, such as throughput and response time, is easily accomplished. GPRS Gb monitor. The GPRS Gb Analyzer application, which is placed on top ofthe GPRS Gb Monitor, provides crucial statistics, detects failedGMM, SM procedures and enables easy and rapid troubleshooting. Solutions for Active Testing Simulation/Emulation of GPRS Network Elements Create and emulate functioning network elements for test purposes. Emulatemultiple network elements (NE) in parallel to real NE for complex testscenarios. Compare reaction of emulated to real NE. Home Location Register Emulation Replace expensive Home Location Register (HLR) in test networks. Takeadvantage of features such as fault tolerant reaction and fast reset capability.Parameters are easy to set. Base Station Subsystem and Mobile Emulation Emulate thousands of mobiles (MS) on multiple Base Station Subsystems(BSS) with one K1297 Protocol Tester. By emulating MS and BSS, you'llbe able to identify Network Switching Subsystem (SGSN, GGSN, HLR, PDN)problems quickly and easily. Network Switching Subsystem Emulation Browse the Web with a GPRS mobile and BSS connected to K1297-G20 ProtocolTester, replacing the entire GPRS core network. Find BSS or mobile problemsby reducing error possibilities by emulating the complete Network SwitchingSubsystem (NSS). Short Message Service Testing Ensure Short Message Service (SMS) functionality via GPRS Gb-and Gd-interface. Integrated Test Functions Integrated test functions in Mobile/Base Station Subsystem provide fastand easy testing and execution of: GPRS attach/detach IMSI attach/detach Combined GPRS/IMSI attach/detach Location area updates Routing area updates Cell reselection PDP Context activation/modification/deactivation Transfer of IP data Paging for CS and PS Enhanced Test Tools The enhanced Test Management System enables local and/or remote automatedand regression testing with the K1297-G20, reducing manual test time.ISO Standards require change management support; with the "shared filesystem approach," users can fulfill these requirements and successfullycomplete regression testing according the ISO standards. Automaticallyrecording files for all test cases provides test results in full detail,down to the bit level, if needed.
