Abstract

Systems and methods for remote file access are disclosed: According to an embodiment, a local agent polls a server for a task request at a polling interval scheduled by a schedule timer in accordance with a set of local agent and remote client preferences. The local agent is responsible for executing a task from the task request and causing a file to be uploaded to the server. The local agent uses a task processor for polling a server, a schedule timer for controlling polling, and one or more protocol stacks, such as TCP/IP and SOAP, for communicating with the server. The local agent can also interface with a MAPI database for message delivery.

Claims

1. A method performed by a server to provide remote access to files requested by a client device, the method comprising:

receiving a client-initiated request for a file, the request received by the server;

entering the request in a queue of the server;

receiving, from an agent device, a polling message requesting information from the server queue;

sending the client-initiated request for a file from the queue of the server to the agent device, wherein the agent accesses the requested file;

receiving the requested file sent by the agent device to the server;

sending, by the server, notification to the client device that the received file is available;

receiving, by the server, instructions from the client device directing the transfer of the received file to a destination device; and

transferring, from the server to the destination device, the received file, wherein the agent device, the client device, the destination device, and the server are located remotely on a network.

2. The method of claim 1, wherein the method step of receiving, from an agent device, a polling message requesting information from the server queue further comprises receiving, at the server, a polling message from an agent device and checking the queue for a new request from one of a portable digital assistant, a two-way pager, and a laptop computer.

3. The method of claim 1, wherein the method step of transferring, from the server to the designation device, the received file comprises transferring the received file from the server to one of a client device, a speech module connected to the client device, and a telephonic device located in other than a client device location.

4. The method of claim 1, further comprising:

storing the request in a first portion of a cache; and

storing the received file in a second portion of the cache.

5. The method of claim 4, wherein the instructions from the client device indicates how to transfer the received file, and the received file is transferred from said second portion of the cache to the remote client in response to the instruction.

6. The method of claim 4, further comprising removing the received file from the second portion of the cache.

7. The method of claim 1, wherein the destination device is another client device.

8. The method of claim 1, wherein the request comprises a file lock mode indicating a scope of use for the requested file.

9. The method of claim 1, wherein the request comprises an indication of a file system of the agent device.

10. The method of claim 4, wherein the received file is deleted from the second portion of the cache after said transferring.

11. The method of claim 10, wherein the received file is deleted from the second portion of the cache after said transferring upon expiration of a predetermined timeout period.

12. A computer-readable storage medium containing instructions which, when executed by a computer, perform a server method of providing access to a file, the method comprising:

receiving a client-initiated request for a file, the request received by a server;

entering the request in a queue of the server;

receiving, from an agent device, a polling message requesting information from the server queue;

sending the client-initiated request for a file from the queue of the server to the agent device, wherein the agent accesses the requested file;

receiving the requested file sent by the agent device to the server;

sending, by the server, notification to the client device that the received file is available;

receiving, by the server, instructions from the client device directing the transfer of the received file to a destination device; and

transferring, from the server to the destination device, the received file, wherein the agent device, the client device, the destination device, and the server are located remotely on a network.

13. The computer-readable storage medium of claim 12, wherein the step of receiving, from an agent device, a polling message requesting information from the server queue further comprises receiving, at the server, a polling message from an agent device and checking the queue for a new request from the client device.

14. The computer-readable storage medium of claim 12, wherein the step of transferring, from the server to the designation device, the received file comprises transferring the received file from the server to one of a client device, a speech module connected to the client device, and a telephonic device located in other than a client device location.

15. The computer-readable storage medium of claim 12, further comprising:

storing the request in a first portion of a cache; and

storing the received file in a second portion of the cache.

16. The computer-readable storage medium of claim 15, wherein the instructions from the client device indicates how to transfer the received file, and the received file is transferred from said second portion of the cache to the remote client in response to the instruction.

17. The computer-readable storage medium of claim 15, further comprising removing the received file from the second portion of the cache.

18. The computer-readable storage medium of claim 15, wherein the destination device is another client device.

19. The computer-readable storage medium of claim 15, wherein the request comprises a file lock mode indicating a scope of use for the requested file.

20. The computer-readable storage medium of claim 15, wherein the request comprises an indication of a file system of the agent device.

21. The computer-readable storage medium of claim 15, wherein the received file is deleted from the second portion of the cache after said transferring.

22. The computer-readable storage medium of claim 21, wherein the received file is deleted from the second portion of the cache after said transferring upon expiration of a predetermined timeout period.

23. A system comprising at least one hardware processor and at least one memory communicatively coupled to said hardware processor, the at least one memory having stored therein computer-executable instructions that, when executed by said hardware processor, cause the system to perform steps comprising:

receiving a client-initiated request for a file, the request received by the system;

entering the request in a queue of the system;

receiving, from an agent device, a polling message requesting information from the system queue;

sending the client-initiated request for a file from the queue of the system to the agent device, wherein the agent accesses the requested file;

receiving the requested file sent by the agent device to the system;

sending, by the system, notification to the client device that the received file is available;

receiving, by the system, instructions from the client device directing the transfer of the received file to a destination device; and

transferring, from the system to the destination device, the received file, wherein the agent device, the client device, the destination device, and the system are located remotely on a network.

24. The system of claim 23, further comprising a database management system that holds client information, agent information, and information relating users of the system.

25. The system of claim 23, communicatively coupled to a speech module for translating text from the file into speech directed to the client.
