Abis cell analyser software for protocol monitor
1 August 2001
Test & Measurement
A new software version has been released for Tektronix's K12xx protocol monitor. Cell analyser is an Abis post-processing software tool that enables the user to perform detailed analysis on the quality of service in GSM networks.
The product performs a range of statistical analyses on Abis interface data in order to allow engineers to make decisions to enhance the quality of service (QoS) of the radio sub-system. The cell analyser software runs on the Tektronix K12xx protocol analyser or alternatively on any PC meeting the system requirements. RF optimisation engineers and operation and maintenance teams use the product typically for ad hoc optimisation, troubleshooting or for cell sanity checks.
The presentation of results from cell analyser is such that the user can quickly drill-down from high-level statistics to the cause of the QoS degradation in a few mouse clicks. This leads to substantial improvements in the effectiveness and productivity of cell analyser users.
As cell analyser runs under the MS Win95/98/NT, it can run on the Tektronix K12xx protocol analyser itself which removes the need to transfer the raw Abis data to a PC for further processing. Alternatively, it could be installed on any PC meeting the system requirements.
Cell analyser preprocesses the raw data and provides the mechanisms to visualise the results. This 'filtering' picks out only the significant data required resulting in much more manageable file sizes that can be transferred easily from the field via e-mail.
A benefit of cell analyser is that the information is presented in such a way that the engineer does not require an understanding of signalling in general or Abis signalling in particular. All information is presented with an RF look and feel. This reduces the training requirements dramatically and thereby increases the effectiveness of the engineers using cell analyser.
