Abstract

A method of managing system faults which enables system operators to easily detect the state of all the systems constituting the Home Location Register (HLR). Even when several sites are added, resulting in different system configuration, the inventive method can be easily applied to such configuration by introducing a novel technique in which the system operator prepares the graphics configuration capable of modifying only the data file as desired on the basis of the previously prepared programs without necessitating the help of professional programers. The method enables reconfiguration to be separately applied to the sites irrespective of changes in the internal hardware and software structure, which results in the reduction of manpower and accordingly of the operating expenses. Furthermore, the visual and audio warning system for fault management provides the system operators with added convenience for system operation, and improved system reliability by reconfiguring the state information when an inconsistency between the actual system and the configuration information at the operation terminal occurs.

Claims

1. A method of managing system fault in a CDMA home location register (HLR), comprising the steps of:

preparing full-mounted configuration information in a graphics mode so that all internal equipment within systems contained in the home location register can be configured to a maximum upon configuration of initial screens;

storing said configuration information in a database;

receiving state information about the internal equipment transmitted from each of the HLR systems after initializing all of said equipment such that each carries "Not Equip" state information; and

visually displaying a fault state of said equipment onto a graphics figure on a screen corresponding to the relevant equipment by means of said received state information and said configuration information stored in said database corresponding to said received state information, and generating an audible warning with respect to said displayed fault state.

2. The method of managing system fault as defined in claim 1, wherein said graphics figure further comprises:

a main screen graphic expressed such that a complete view of the entire state of each system can be displayed to the operator;

a system screen graphic expressed such that a systematic view of the states of each of said systems can be displayed to the operator; and

a board mounting screen graphic displayed on the screen by combining the states of boards mounted on front and back sides, and software screen graphics expressed by combining software states of processes to be performed in each of said systems.

3. The method of managing system fault as defined in claim 2, wherein said graphics are deployed on screen in top-down order of the main screen graphic, the system screen graphic, the board mounting screen graphic, and the software screen graphic.

4. The method of managing system fault as defined in claim 1, wherein said visual display varies depending on fault levels, wherein a critical fault state is expressed in red, a major fault state is expressed in orange, a minor fault state is expressed in yellow, a normal said fault state is expressed in green, and when no state information is present, said fault state is expressed in black color.

5. The method of managing system fault as defined in claim 4, wherein said audible warning for said fault states employs different alarm sounds depending on said fault levels.

6. A method of compensating for inconsistencies between the current fault states of systems constituting the CDMA home location register (HLR) and the fault graphics states displaying said fault states, comprising the steps of:

initializing an expression of said fault graphics states according to an operator request when said fault states of said systems are inconsistent with said fault graphics states;

reconfiguring the current fault state information by requesting and receiving the current fault state information transmitted from said systems; and

displaying said fault graphics state on said screen in response to said reconfigured fault state information.

7. The method as defined in claim 6, wherein a reconfiguring button is provided on the displayed main screen to enable the operator to display a complete view of the entire states of all the systems.

8. A method for processing fault events occurring in systems constituting a CDMA home location register (HLR), comprising the steps of:

analyzing state information received from faulty equipment within the systems;

updating an internal fault details storing unit corresponding to the state information of the equipment;

updating the color of a higher graphics figure representative of relevant equipment presented on a main screen and being continuously displayed by combining fault levels based on said state information;

determining whether a detailed screen corresponding to said relevant equipment is currently displayed;

presenting each of the graphic figures of said relevant equipment in the updated fault level colors when said detailed screen corresponding to said relevant equipment is displayed on the current screen; and

generating audible warnings depending on said fault levels based on said updated state information stored in said internal fault details storing unit.

9. The method for processing fault events as defined in claim 8, wherein said fault level color is presented in red when the fault state is critical, in orange when the fault state is major, in yellow when the fault state is minor, in green when the fault state is normal, and in black when the fault state information is missing.

10. The method for processing fault events as defined in claim 8, wherein said audible warning is selectively deactivated by the operator.

11. The method for processing fault events as defined in claim 8, wherein said audible warning is automatically turned on upon occurrence of a fault, irrespective of the operator'"'"'s previous deactivation of the same.

12. The method for processing fault events as defined in claim 10, wherein an audio warning selection button to be activated by said operator is displayed on the main screen such that said operator can get a complete view of the states of all the systems.

13. The method for processing fault events as defmed in claim 11, wherein an audio warning selection button to be activated by said operator is displayed on the main screen such that said operator can get a complete view of the states of all the systems.
