1 Introduction
1.1 Parameter Classification
The GSM and GPRS parameters are classified into three categories:
Network: customer dependent parameters, related to the network topology,
defined by the customer and valid for the complete network (e.g. BTS name,
Cell ID, LAC number ...). They can be adjusted by CDE scripts.
Site: adjustable parameters from one cell to the next or from one BSC to the
next. They are set to a default value. They can be adjusted from the OMC-R.
System: fixed parameters, i.e. BSS system mandatory rules or
automatically populated in the DLS skeleton and let unchanged because
not customer dependent. Some of them are coded in BTS Software and
configuration files.
1.2 Parameter Description
To each parameter are associated the following characteristics:
Logical Parameter Name: Mnemonic conventionally used in Alcatel
documentation.
Definition: definition/purpose of the parameter.
Coding rules:, Rules of coding, when necessary.
Mandatory rules: Mandatory relationships or inter-dependence of some
data.
Recommended rules: Recommended relationships or inter-dependence
of some data.
Feature: Indicates to which feature the parameter is linked.
Category: Category into which the parameter is classified.
Instance: Possible instance of the parameter.
Value
Min/Max values: Possible range of the parameter values.
Default value: Parameter value in release B9 for a generic configuration.
Modifiable: Indicates if the parameter is modifiable at the OMC-R.
Parameter Access: Indicates where the parameter is accessible at the
OMC-R.
External Comments: Specific information, when necessary, related
to the parameter.
