The GPB operates as a Main Processor (MP). It contains and executes the main part of the RNC

software. In MS four GPB pairs are duplicated to provide redundancy. In case of failure in the

active board, the standby GPB takes over the role as active. The remaining GPBs are Pooled

Module MPs.

The GPB is equipped with Ethernet and asynchronous serial interfaces accessible from the board

PMS� PMS GUI is used for data collection subscription profiles management.

Subscription Profiles and Performance Monitoring functionality of OSS provide measurement management and result file collection support for:

– Performance Management Statistics, Recordings and GPEH functions of WCDMA RAN and TD-SCDMA RAN

– Performance Management Statistics, Cell Trace and UE Trace functions of LTE RAN

� Measurement management functionality allows you to manipulate (that is, create, resume, suspend, delete and modify) performance measurements towards the radio network.

� All active measurements in the network produce measurement results every 15 minutes in the form of one or several Report Output Period (ROP) files on each relevant Network Element (NE). ROP files are then automatically collected by the Subscription Profiles and Performance Monitoring function and stored in the local OSS file storage where they are made available for further processing. These files are fetched by external management systems or processed by internal OSS functions such as Network Statistics (NWS) or Recording and Events Interface (REI).
