6 Functions
The RBS functions can be subdivided into RBS application functions 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 16.

Figure 4 Main RBS Application Function Groups
Measurement functionality is subdivided 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.
6.1 Application Functions
The application functions of the RBS are subdivided into function groups each
covering some specific RBS functionality. See table 2 for RBS function groups.
