23.2.2 Application Object Configuration
Each AO has a number of associated configuration parameters which
control the way in which it functions.
An AO has two states relevant to configuration:
• Enabled
• Disabled
The configuration of an AO by the BSC involves three distinct
operations performed over the A-bis OML:
• Configuration
• Enable
• Disable
Configuration
The process of setting the desired configuration parameters for an AO.
For most AOs and most configuration parameters this process must be
performed while the AO is disabled. However there are a number of
exceptions, certain parameters on certain AOs may be configured by the
BSC while the AO is enabled.
When a configuration request is received over the A-bis, this function
checks that all preconditions for a change in configuration are satisfied:
• All parameters are within the permitted range or have permitted
values
• If the AO is enabled, parameters that cannot be changed in
enabled state must not be changed
• For certain classes of AO, the configuration parameters must be
consistent with each other
The BSC is informed of the successful configuration of the AO or, if
unsuccessful, an indication of why the configuration failed is returned.
Enable
Enable attempts to activate an AO with the current configuration
parameters.
When an enable request is received via A-bis, this function checks that
all preconditions for a change to enabled state are satisfied:
• All required configuration parameters must be previously set by
one or more configuration procedures
• Configuration parameters must be consistent with each other
If all checks are successful, the function of the appropriate AO is
enabled.
The BSC is informed of the successful enable of the AO or, if
unsuccessful, an indication of why the enable was unsuccessful is
returned.
