Synchronization Synchronization functions provide
correct data timing, and prevent data
loss due to slip of sent and received
information through the system.
They also provide stable frequency
references for RF stabilization.
Synchronization functions are
managed through the Mub interface.
Synchronization frames are carried
over the Iub interface to and from
RNC.
Bearer Bearer functions transfer user or
control data between the RNC and
RBS. The data is carried over the Iub
interface
Traffic Control Traffic control functions provide
control of traffic-related resources
such as common and dedicated
radio connections, cells and ATM
connections. They also provide
control of measurement requested
from the RNC. Traffic control is
performed through the Iub interface
and is managed over the Mub
interface.
Configuration Management Configuration management functions
create and delete RBS Managed
Objects (MO). Attributes of these
MOs can be set and read. These
functions are performed over the Mub
interface. Some functionality also
exists that uses the Iub interface.
Fault Management Fault management functions detect,
isolate, and recover from faults in
supervised functions. Faults are
reported through alarms, that also
are logged and maintained in an
active alarm list. Alarm handling
is performed through the Mub
interface. Supervision functions are
always active and do not have to be
configured.
Performance Management Performance management functions
collect, store and report statistics
regarding RBS measurements.
These functions are performed
through the Mub interface.
