The invention relates to an operation and maintenance system for a mobile telecommunications network. According to the invention, a network configuration can be executed centrally by a maintenance device (OMT) of an operation and maintenance centre (OMC) and peripherally using an LMT maintenance device (LMT, LMTr). Said LMT maintenance device can be connected to a network device (BSC, BTSE, TRAU) of a base station sub-system of the mobile telecommunications network. An LMT access table (TB) containing a user data set with a name entry for each user entitled to access the operation and maintenance system using the LMT maintenance device (LMT, LMTr) is stored in the operation and maintenance centre (OMC). Said access table (TB) also contains a specific user password (password) for use by the user to gain access via the LMT maintenance device (LMT, LMTr), and information relating to the extent of said user's access rights. A control system in the operation and maintenance centre (OMC) administers the LMT access table (TB) and ensures that at least the part of said LMT access table (TB) needed to gain access using an LMT maintenance device (LMT, LMTr) via network devices is stored in said network devices in a non-volatile way. |
