Abstract

A software roaming system, method and a computer readable storage medium thereof are disclosed herein. The software roaming system includes a first electronic device having a plurality of widget software. The first electronic device includes a device description data. The device description data includes virtual units corresponding to the widget software, wherein the first electronic device establishes the virtual units in accordance with a universal plug and play (UPNP) protocol. The first electronic device searches a second electronic device through an network in accordance with the UPNP protocol and copies a first widget software of the widget software and a runtime data thereof to the second electronic device, and thus the second electronic device installs the first widget software and recovers the runtime data.

transferring the serialized runtime data to the second electronic device by the content exchange service corresponding to the first widget; and

un-packaging and de-serializing the runtime data to recover the runtime data to the second electronic device.

6. The software roaming method of claim 2, wherein the step of copying the first widget comprises:

packaging and serializing the runtime data and the first widget of the first electronic device;

transferring the serialized first widget to the second electronic device by the software exchange service; and

transferring the serialized runtime data to the second electronic device by the content exchange service corresponding to the first widget.

7. The software roaming method of claim 6, wherein the step of installing the first widget to the second electronic device comprises:

un-packaging and de-serializing the first widget data and the runtime data to recover the first widget and the runtime data to the second electronic device.

8. A computer readable medium for performing a software roaming method, the software roaming method comprising:

respectively detecting a plurality of widgets of a first electronic device and a second electronic device, wherein the first electronic device is connected to the second electronic device through a network;

establishing a first device description data in accordance with a universal plug and play protocol and the widgets of the first electronic device;

establishing a second device description data in accordance with the universal plug and play protocol and the widgets of the second electronic device;

selecting a first widget from the widgets of the first electronic device according to the first device description data and the second device description data;

copying the first widget and a runtime data of the first widget from the first electronic device to the second electronic device; and

installing the first widget to the second electronic device and recovering the runtime data.

9. The computer readable medium of claim 8, wherein the first electronic device is a root device and is configured to provide a software exchange service, each of the first device description data and the second device description data comprising a plurality of virtual units, wherein the virtual units of the first device description data are corresponding to the widgets of the first electronic device, and the virtual units of the second description data are corresponding to the widgets of the second electronic device.

10. The computer readable medium of claim 9, wherein each of the virtual units provides an identification service and a content exchange service, the step of selecting the first widget from the widgets of the first electronic device comprising:

comparing the first device description data and the second device description data to check whether the second electronic device has the virtual unit corresponding to the first widget; and

selecting the first widget when the second electronic device does not have the virtual unit corresponding to the first widget.

11. The computer readable medium of claim 10, wherein the step of selecting the first widget from the widgets of the first electronic device comprises:

identifying whether a software version of the first widget of the first electronic device and the software version of the first widget of the second electronic device are the same by the identification service provided from the virtual unit, corresponding to the first widget of the second electronic device, when the second electronic device has the virtual unit corresponding to the first widget; and
