Overview
UMTS (Universal Mobile Telecommunications System) being an access network in the mobile communication area
provides a common interface to both GSM and GPRS core network. UMTS is capable of handling both Circuit-Switched (CS)
as well as Packet-Switched (PS) data simultaneously through its UTRAN network.
UMTS separates the user plane from control plane, radio network plane from the transport network plane, access
network from the core network, and access stratum from the non-access stratum. Separation of transport network
subsystem and radio network subsystem enables the UMTS to use multiple transport layer mechanism.
IP and ATM are the most preferred transport network layer protocols used in UMTS network architecture. ATM based
UMTS network is more popular since it ensures various QoS and Classes of Services to the end user.
GL’s OC3 / 12 and STM1 / 4 UMTS analyzer is capable of capturing, decoding, and performing various test
measurements across various interfaces i.e. Iub, Iur, IuCs and IuPs interfaces of the UMTS network based ATM transport
layer. It helps in fault diagnosis and troubleshooting of UMTS network. Multiple instances of UMTS Analyzer can run
simultaneously capturing data (real time and off-line) on multiple OC-3 or OC-12 interfaces.

Real-time and Offline Analysis
Users can capture and analyze UMTS frames in real-time and record all or filtered traffic into a trace file. The recorded
trace file can then be analyzed offline and exported to ASCII file, or printed. UMTS raw data capturing requires user to
specify timeslots, bit inversion, octet bit reversion, user/network side, ATM mapping, scrambling, and inverse multiplexing
(IMA) options. The real-time data capturing requires user to specify ports and user/network side.

Port Selection for Real-time
Capture
Filtering and Search
Users can record all or filtered traffic into a trace file. Filtering and search capability adds a powerful dimension to the
UMTS Analyzer. This feature can isolate required frames from all frames in real-time, as well as offline. Users can specify
custom VPI, VCI, and PT type values to filter frames during real-time capture. The frames can also be filtered after
completion of capture based on Frame Number, Time, Length, Error, VPI, VCI, PT, OSF, AAL Type, CID, LI, UUI, and more.
Similarly, Search capability helps user to search for a particular frame based on specific search criteria.

rules defined by the specified AAL type.

Protocol Analysis
Call Detail Record and Statistics View
Call trace defining important call specific parameters like Call ID, Call disposition, Call duration, Mobile ID,
Called/Calling Number, Call type (SMS/PDP/Setup/Location update etc) are displayed for IuCs and IuPs interfaces.
Statistics is an important feature available in UMTS analyzer and can be obtained for all frames both in real-time as
well as offline mode. Various statistics can be obtained in statistics view to study the performance and trend in the ATM
network based on different parameters e.g. Use Type, Statistic type (Frame count, Byte count, Frames/Sec) and patterns
(Range List, Wild card).

Analysis
Enhanced Trace Saving Options
Users can control the captured trace files by saving the trace using different conventions such as trace files with
user-defined prefixes, trace file with date-time prefixes, and slider control to indicate the total number of files, file size,
frame count, or time limit. This feature also allows the captured frames to be saved into a trace file based on the filtering
criteria
