Fault detection functions in the resource layer, and also in the common platform,
ensure fault and error detection. The hardware layer within the resource layer
provides fault and error detection support on a low level. However, it has
no direct interface to the management adaptation layer. The management
adaptation layer and the common platform generate the corresponding alarms.
Events can have their origin in any part of the system, but the management
adaptation layer and the common platform generate the event reports.
5 Functions
The RBS functions can be divided into RBS application and common platform
functions. RBS application functions use common platform functions to realize
their tasks. An overview of the main RBS application function groups and their
interfaces is given in figure 4. The interfaces are described in page 15.
Figure 4 Main RBS Application Function Groups
Measurement functionality is divided into a detector part (normally in radio
transport functions) and a control part, that controls the measurement.
Measurement functions have different roles in the measurement functionality.
The O&M for traffic control functions is included within the function itself.
Security aspects are handled within each function that interfaces with the Mub.
Security support is provided by the platform functions.
Functions that have an interface for management only cover functionality
towards an Mub user. The Mub user can be either an element management
node or RANOS.
5.1 Application Functions
The application functions of the RBS are divided into function groups each
covering some specific RBS functionality. See table 1 for RBS function groups.
Table 1 RBS Function Groups
Function group Task
Radio Transport Radio transport functions manages
user data processing in the baseband
and RF parts of the RBS node.
It handles the air interface Uu.
Measurement detector functionality is
also included.
