Functionality Administration
23 Functionality Administration
"Functionality Administration" provides the functionality necessary to
allow the BSC to configure, enable and disable AOs within the RBS.
This function also includes general layer 3 A-bis OML support for other
functions within the RBS.
23.1 Concepts
Application Object An abstract subclass of MO, which
provides part of the functionality of a BTS
Elementary Procedure The protocol over the A-bis OML at layer
3 consists of EPs (Elementary
Procedures). An EP is a unit of interaction
between the BSC and one of the MOs. An
EP consists of an initiating message and a
response. For example, an EP may consist
of the BSC sending an initiating message
CONFIGURE REQUEST and the MO in
the RBS responding with a message
CONFIGURE REQUEST ACK.
Managed Object The BSC manages the O&M of the RBS
via the A-bis O&M Interface. The RBS
equipment is seen as MOs by the BSC.
This is a means of describing the RBS in a
function-oriented way, and a logical model
of the RBS in terms of MOs is built in the
BSC. All O&M actions are based on this
logical model structure created in the BSC.
An MO does not necessarily have a one-
to-one relation with a physical unit in the
RBS, and the MO comprises both
hardware and software.
