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.

Concepts

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.

Replaceble Unit. An RU is the smallest
unit that can be handled on site or in a
repair center and of which information can
be retrieved via OMT or BSC.

Application Object. An abstract subclass
of MO, which provides part of the
functionality of a BTS

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 functional-
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 either both
hardware and software or software only.
