System and method for interruption-free file access

An on-line game information service system for providing interruption-free game information access service to a plurality of game players communicating to said system via Internet, said system comprising:

• a main program subsystem executing a main program for providing said game information access service to said players by receiving I/O access requests issued by said players;
• an information storage subsystem for storing game information required for implementing said game information service;
• and
• an I/O access agent subsystem processing said I/O access requests issued by said players by registering said requests received by said main program subsystem and submitting said received requests to said game information storage subsystem for implementing the read or write accesses corresponding to said requests, said I/O access agent subsystem relaying the result of said requests to said main program subsystem for returning to said players upon completion of said submitted requests.

A method for providing interruption-free file access service to users communicating to an information service via a communications network in an information service system comprising a main program subsystem, an information storage subsystem and an I/O access agent subsystem, said method comprising the steps of:

• a) said main program subsystem registering information access requests issued by said users in a list and submitting said requests to said I/O access agent subsystem;
• b) said I/O access agent subsystem submitting said requests issued by said users to the information subsystem for implementing read or write accesses corresponding to said requests;
• and
• c) said I/O access agent subsystem relaying the result of said requests to said main program subsystem for returning to said users upon completion of access of said submitted requests by said information storage subsystem, wherein said information service system continuing said information service for said users before said completion of an I/O access that is pending.
