UMTS Protocol Analyzer for OC-3/STM-1
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.
GLís 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.
Screen Shot of UMTS Protocol Analysis Main Window
- Displays Summary, Detail, Hex-dump, and Statistics Views
- Detail View
- Displays decodes of a user-selected frame from the summary view
- Provides options to display or hide the required protocol layers
- Contents of this view can also be copied to clipboard
- Summary view provides the information about few important fields (Dev #, Time Slot, VPI/VCI, PT, OSF, AAL type, CID, ALCAP message) in a tabular format.
- Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields.
- Decodes different control plane protocols i.e. NBAP, RANAP, RNSAP, ALCAP, SSCOP etc and user plane protocols i.e. Iu-UP, Iub-FP, AMR and more.
- Decode NAS protocols (i.e. CC/MM/SM/SMS/GMM) along with the UTRAN specific protocols.†
|Filtering and Search
||Advanced filtering and search based on any user selected protocol fields
|Capturing Streams and Decoding Frames
- Captures, decodes, filters, and reassembles AAL-2 and AAL-5 frames in real-time, from within the ATM cells according to user defined VPI/VCI.
- Supports simultaneous decode of multiple streams of UMTS traffic on multiple OC-3 or OC-12 interfaces.
- Exports Summary View information to a comma delimited file for subsequent import into a database or spreadsheet.
- Capability to export detailed decode information to an ASCII file
|Additional Features of ATM
- Ability to configure .ini file for VPI & VCI (for ALCAP, NBAP, RANAP, and so on).
- Performs numerous measurements across Iub, Iur, IuCs and IuPs interfaces.

Summary, Detail, and Hexdump Views
The analyzer displays Summary, Detail, Hex Dump, Statistics, and Call Detail Views in different panes. The summary
pane displays Frame Number, Time, Length, Error, VPI, VCI, PT, OSF, AAL Type, CID, LI, UUI, CPI and Frame Type message.
User can select a frame in summary view to analyze and decode each frame in the detail view. The Hex dump view
displays the frame information in HEX and ASCII format.

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
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.

Criteria for UMTS Protocol Analysis
Using reassembly option user can specify VPI /VCI value to reassemble as per the Segmentation and Reassembly
rules defined by the specified AAL type.

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).
Statistics Options for UMTS Protocol
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
