Abstract

A method is disclosed for communicating using a device having a PALM® OS. SMB is used to communicate with a node, and if use of SMB is not possible, FTP is used, and if use of FTP is not possible, BLUETOOTH® is used. If FTP or BLUETOOTH® is selected, file sharing between the device and node that entails a read or write is executed by temporarily copying a file to an internal PALM® OS memory of the device, performing the read or write on the file, and then copying the file back to the node to overwrite a previous version of the file at the node. For non PALM® OS file transfer to the internal memory, the file is wrapped in a PALM® OS stream in the internal memory for executing reads or writes.

Claims

1. A method for communicating using a mobile communication device, the method comprising:

in the mobile communication device;

communicating with a node using server message block (SMB) communication protocol;

communicating with the node using file transfer protocol (FTP), if use of SMB communication protocol to communicate with the node is not possible;

communicating with the node using BLUETOOTH®

communication protocol, if use of FTP and SMB to communicate with the node is not possible, wherein the mobile communication device operates using a first operating system (OS); and

receiving at least one file in a second OS format from the node, wherein receiving the file comprises;

storing the file in at least one internal memory of the mobile communication device, and

wrapping the file in a first OS stream in the at least one internal memory,

wherein the first OS is different from the second OS and wherein the first OS has a subset of capabilities of the second OS.

2. The method of claim 1, wherein if a protocol for communication between the mobile communication device and the node has not been identified, determining whether the node can communicate using a SMB communication protocol dialect available to the mobile communication device, and if so, selecting SMB communication protocol to communicate with the node.

3. The method of claim 2, wherein if the node cannot communicate using the SMB communication protocol dialect available to the mobile communication device, the node is queried with an FTP message and if an FTP associated response is received, FTP is selected to communicate with the node.

4. The method of claim 3, wherein if the FTP associated response is not received, identifications of devices are attempted to be gathered using BLUETOOTH®

communication protocol, and if an identification matches an identification of the node, BLUETOOTH®

communication protocol is selected to communicate with the node.

5. The method of claim 1, wherein if SMB communication protocol or BLUETOOTH®

communication protocol is selected for communication with the node, a user name is automatically set to a default name.

6. The method of claim 1, wherein if FTP or BLUETOOTH®

communication protocol is selected, file sharing between the mobile communication device and the node that entails a read or write is executed by temporarily copying a file to the at least one internal memory of the mobile communication device, performing the read or write on the file, and then copying the file back to the node to overwrite a previous version of the file at the node.

7. The method of claim 1, further comprising transferring at least one file between an expansion first OS memory of the mobile communication device and the node by byte-to-byte copying of the file using a file allocation table (FAT) of the expansion first OS memory, wherein the file being transferred through the at least one internal memory of the mobile communication device.

8. The method of claim 1, wherein the first OS comprises a PALM®

OS.

9. A system, comprising:

at least one processor, wherein the processor operates using a first operating system (OS);

at least one internal memory; and

a protocol stack communicating with the processor, wherein the protocol stack comprises;

an application layer having at least two application layer protocols selected from a group comprising BLUETOOTH®

communication protocol, file transfer protocol (FTP), and server message block (SMB) communication protocol; and

a protocol selection layer on top of the application layer for selecting which application layer protocol to use to communicate with a node, wherein the protocol selection layer uses SMB communication protocol to communicate with the node, and if use of SMB communication protocol to communicate with the node is not possible, use FTP or BLUETOOTH®

communication protocol, and wherein the processor receives at least one file in a second OS format from the node by;

storing the file in the at least one internal memory, and

wrapping the file in a first OS stream in the at least one internal memory,

wherein the first OS is different from the second OS and wherein the first OS has a subset of capabilities of the second OS.

10. The system of claim 9, wherein the application layer has all three application layer protocols.

11. The system of claim 9, further comprising a PALM®

OS transport control protocol/internet protocol (TCP/IP) layer and a session layer, wherein session layer is in between the PALM®

OS TCP/IP layer and a layer associated with the SMB communication protocol, wherein the session layer comprises a net basic input/output system (NetBIOS) layer and wherein the first OS comprises a PALM®

(OS).

12. The system of claim 9, wherein if FTP or BLUETOOTH®

communication protocol is selected, the first OS executes file sharing with the node that entails a read or write by temporarily copying a file to the at least one internal memory, performing the read or write on the file, and then copying the file back to the node to overwrite a previous version of the file at the node.

13. The system of claim 9, further comprising an expansion first OS memory, wherein the first OS transfers at least one file between the expansion first OS memory and the node by byte-to-byte copying of the file using a file allocation table (FAT) of the expansion first OS memory, the file being transferred through the at least one internal memory.

14. A mobile communication device, comprising:

at least one internal memory;

at least one expansion memory; and

one or more processors operable to;

determine whether a node can communicate using a server message block (SMB) communication protocol dialect available to the mobile communication device;

select SMB communication protocol, if SMB communication protocol for communication between the mobile communication device and the node is possible;

query the node with an FTP message, if the node cannot communicate using the SMB communication protocol dialect available to the mobile communication device;

select FTP, if an FTP associated response is received;

gather identifications of devices using BLUETOOTH®

communication protocol, if the FTP associated response is not received;

select BLUETOOTH®

communication protocol, if an identification matches an identification of the node, wherein the mobile communication device operates using a first operating system (OS); and

receive at least one file in a second OS format from the node, wherein receiving the at least one file comprises;

store the file in the at least one internal memory, and

wrap the file in a first OS stream in the at least one internal memory,

wherein the first OS is different from the second OS and wherein the first OS has a subset of capabilities of the second OS.

15. The mobile communication device of claim 14, wherein if SMB communication protocol or BLUETOOTH®

communication protocol is selected the one or more processors are operable to automatically set a user name to a default name.

16. The mobile communication device of claim 14, wherein if FTP or BLUETOOTH®

communication protocol is selected, file sharing between the mobile communication device and the node that entails a read or write is executed by temporarily copying a file to the at least one internal memory of the mobile communication device, performing the read or write on the file, and then copying the file back to the node to overwrite a previous version of the file at the node.

17. The mobile communication device of claim 14, wherein the one or more processors are operable to transfer at least one file between the at least one expansion memory and the node by byte-to-byte copying of the file using a file allocation table (FAT) of the at least one expansion memory, wherein the file is transferred through the at least one internal memory of the mobile communication device.
