EBS (Event Based Statistics)

The data in this database will act as a complement to the STS database but it is of more detailed character than the STS statistics. The data can either be stored in the database or in a Bulk Copy format file that can be distributed to other postprocessing tools. The monitors (counters) that can be stored must be activated in the GUI by the user, the user must have the correct authority to perform this action. The user must also select if the counters are to be collected for all cells in a specific BSC or several/all BSCs. The user can schedule the start and stop of data storage. The aggregation time, i.e. how often data is accumulated, can be decided by the user.

The data can later be postprocessed and reports can be created from monitors stored as counters by using the Business Objects tool. EBS and STS data can preferrably be combined into the same Business Objects report.

Note:  In order to combine STS and EBS data in the same report, it is important that the data is stored with the same periodicity

R-PMO (Realtime Performance MOnitoring)

R-PMO was the first application that was introduced in the family. Its main purpose is to present data in real-time. Realtime is achieved by letting the event data stream continuously to the OSS from the BSCs,and updating the OSS GUI once every minute.

The performance data that can be evaluated in real-time includes traffic load, service quality, hand over, GPRS/EGPRS cell reselection performance, GPRS/EGPRS data throughput and more. The measures are called Monitors.

The monitors are combined into reports. Several pre-defined Ericsson Standard Reports for both circuit switched and packet switched traffic performance monitoring are available. The user can also assemble monitors into own reports by using drag and drop.

A wide range of filters can be used on monitors, depending on the nature of the monitor. As an example the performance information for circuit switched traffic can be filtered per MS manufacturer and type, and the dropped calls can be filtered per drop reason.

FFAX (Find Faulty Antenna eXpert)

The purpose of FFAX is to provide an efficient way to remotely identify RF paths and antenna installations that are not performing according to expectations.

This is done by monitoring the difference in received signal strength from different RX paths in the BTS.

FFAX in OSS is applicable for the uplink and requires the BSS feature Find Faulty Antenna Data (FFAD). FFAX enables managing of cell sets to monitor, presentation of results in real-time and database storage functionality. For each reported TRX, key values are presented representing the accumulated receiver signal strength difference, during the measurement period, and when relevant an indication of the most likely fault or no fault found. The report will be updated every minute, and can be viewed in table as well as graph format (sliding window displaying data for the last hour). This is ideal during site visits where results of changes to the RF paths can be immediately seen in OSS.
