Remote maintenance and monitoring service framework for heterogeneous device and system

A global server, comprising:

• a second mapping unit mapping a service in order to convert the service into a message;
• a global DB unit storing device information including operation conditions and profiles of systems and devices for maintenance;
• a user maintenance interface receiving a request for a second service and transferring a result for the requested second service to a user;
• a second transaction managing unit extracting a message corresponding to the requested second service from the second mapping unit and generating a second transaction including the extracted message;
• a second transaction processing unit reading the device information from the storage unit or requesting a third service in order to process the message included in the second transaction;
• and
• a local maintenance interface transmitting the requested third service and receiving a result for the third service.

A local server, comprising:

• a third mapping unit mapping a service in order to convert the service into a message;
• a communication unit receiving a request for a third service and a result for the received third service;
• a local DB unit storing device information including operation conditions and profiles of systems and devices for maintenance;
• a third transaction managing unit extracting a message corresponding to the requested third service from the third mapping unit and generating a third transaction including the extracted message;
• a third transaction processing unit reading the device information from the local DB unit or requesting a fourth service in order to process the message included in the third transaction;
• and
• a standard interface transferring the requested fourth service and receiving a result for the fourth service.
