Abstract

A loading error restoring apparatus and method of an exchange are disclosed. A client processor loads a specific program related to a switching system and checks whether a loading error occurs more than a predetermined number of times in the loading process. If so, the client processor transmits a load request signal identifying a requested program to a loading server. In response, the loading server transmits a load reply signal containing the requested program, if it is available. Thereafter, the client processor checks whether the requested program exists in the transmitted load reply signal and loads the transmitted program to an associated disk and memory if the requested program exists.

Claims

1. A loading error restoring apparatus, comprising:

an exchange that provides a prescribed switching function based on a program;

a loading server that stores the program related to the exchange; and

a network that communicatively couples the loading server and the exchange, wherein

if the exchange determines that a loading error has occurred a predetermined number of times during a local loading of the program, the exchange downloads a non-erroneous version of the program from the loading server through the network.

2. The apparatus of claim 1, wherein the exchange comprises:

a disk that stores a number of files used in the exchange;

a memory; and

a client that controls a program loading operation from the disk to the memory and requests the program from an external server when the loading error occurs more than the predetermined number of times.

3. The apparatus of claim 1, wherein the exchange transmits a load request signal to the loading server and receives a load reply signal from the loading server through the network.

4. The apparatus of claim 3, wherein the load request signal comprises:

a packet type;

a type of the exchange;

a program name; and

information on a program version.

5. The apparatus of claim 3, wherein the load reply signal comprises:

a packet type;

a type of the exchange;

a program name;

a program version;

information on a total size of the program; and

the program data.

6. The apparatus of claim 1, wherein the exchange is capable of making a TCP/IP based communication though the network and the network is an internet network.

7. The apparatus of claim 3, wherein the exchange directly transmits the load request signal to the loading server if the loading server has been designated and transmits the load request signal in a broadcast form if no loading server has been designated.

8. A loading error restoring apparatus, comprising:

a disk that stores a program used in an exchange;

a memory;

a client that controls a program loading operation from the disk to the memory and requests the same program as the program with a loading error from an external server if the loading error occurs while loading the program; and

a network that communicatively couples the external server, the client, and a loading server, wherein

the loading server transmits a requested program to the client through the network.

9. The apparatus of claim 8, wherein the client transmits a load request signal containing a type of the exchange, a program name, a program version, and a packet type to the loading server and receives a load reply signal containing a type of the exchange, the program name, the program version, the packet type, a total size of the program and the program data from the loading server.

10. The apparatus of claim 8, wherein the client is capable of making aTCP/IP-based communication through the network and the network is an internet network.

11. The apparatus of claim 9, wherein the client directly transmits the load request signal to the loading server if the loading server has been designated and transmits the load request signal in a broadcast form if no loading server has been designated.

13. The method of claim 12, wherein checking for the loading error further comprises downloading the corresponding program from the loading server if the program does not exist or a file of the program has been damaged in the loading process.

14. The method of claim 12, wherein downloading the corresponding program further comprises:

transmitting a load request signal from the exchange to the loading server;

transmitting a load reply signal from the loading server to the exchange in response to the load request signal;

checking, with the exchange, whether the corresponding program exists in the transmitted load reply signal; and

loading the corresponding program in a disk and in a memory of the exchange.

15. The method of claim 14, wherein transmitting the load reply signal further comprises:

analyzing the load request signal with the loading server to check whether the corresponding program requested in the load request signal exists in the loading server; and

integrating the corresponding program into the load reply signal and transmitting the load reply signal to the exchange, if the requested program exists.

16. The method of claim 15, wherein analyzing the load request signal further comprises setting a program total size as ‘

0’

bytes, if the exchange is not a supportable type or the corresponding program does not exist in a database of the loading server.

17. The method of claim 14, wherein the load request signal comprises:

a packet type;

a type of the exchange;

a program name; and

information on a program version.

18. The method of claim 14, wherein the load reply signal comprises:

a packet type;

a type of the exchange;

a program name;

a program version;

information on a total size of the corresponding program; and

program data.

19. The method of claim 14, wherein checking whether the corresponding program exists further comprises discarding the load reply signal, with the exchange, if a program total size value of the load reply signal is ‘

0’

bytes.

20. The method of claim 12, wherein an internet network communicatively couples the exchange and the loading server and the exchange is capable of making a TCP/IP-based communication through the internet network.

12. A loading error restoring method, comprising:

loading a specific program related to a switching system into an exchange;

checking whether a loading error occurs more than a predetermined number of times in loading the specific program; and

downloading a corresponding program from a loading server if the loading error occurs more than the predetermined number of times.

21. A loading error restoring method, comprising:

loading a specific program related to a switching system into an exchange;

checking whether loading errors occur more than a predetermined number of times while loading the specific program;

transmitting a load request signal from the exchange to a loading server if the loading errors occur more than the predetermined number of times;

transmitting a load reply signal from the loading server to the exchange in response to the load request signal;

checking, with the exchange, whether a requested program identified in the load request signal exists in the transmitted load reply signal; and

loading the requested program on a disk and in a memory of the exchange if the requested program exists.

22. The method of claim 21, wherein checking the loading errors further comprises transmitting the load request signal to the loading server if the specific program does not exist or is damaged in the loading process.

23. The method of claim 21, wherein transmitting the load reply signal further comprises:
