Abstract

An operation and maintenance system for a mobile communications network allows to execute a network configuration centrally from a maintenance device of an operation and maintenance center and allows to execute a network configuration peripherally with the aid of a local maintenance terminal which can be connected to a network device of a base station subsystem of the mobile communications network. An access table contains, for each operator authorized for access to the operation and maintenance system, a name entry, a specific operator password to be used by the operator for access via a local maintenance terminal, and information on the extent of the operator's access authorization. The access table is stored in the operation and maintenance center. A controller in the operation and maintenance center administers the access table and initiates a nonvolatile storing of in each case at least that part of the access table in network devices of the base station subsystem which is required for an access performed with the aid of an LMT maintenance device and performed via these network devices.

Claims22

Dependent claims

An operation and maintenance system for a mobile communications network, comprising:

an operation and maintenance center having a maintenance device and a controller;
a local maintenance terminal operatively connected to said operation and maintenance center;
a base station subsystem connected to said local maintenance terminal and having network devices;
said maintenance device being configured for centrally executing a network configuration, said local maintenance terminal being configured for peripherally executing a network configuration;
said operation and maintenance center storing an LMT access table for an operator authorized to access the operation and maintenance system with the aid of said local maintenance terminal, said LMT access table including an operator record having a name entry, an operator password to be used by the operator for accessing said operation and maintenance center via said local maintenance terminal, and information on an extent of an access authorization of the operator;
and
said controller administering said LMT access table and initiating a nonvolatile storing of at least a part of said LMT access table in said network devices of said base station subsystem, the part of said LMT access table being required for accessing, with the aid of said local maintenance terminal, via said network devices.
