Method, mobile communication device, and system for selective downloading to a mobile communication device
View Patent ↗A method, mobile communication device, and system for selective downloading to a mobile communication device are provided. In accordance with one embodiment, there is provided a method on a mobile communication device for downloading data from a content source to the mobile communication device, the mobile communication device being configured for connecting to at least cellular data networks and wireless local area networks (WLANs), the method comprising: receiving a request to download data; determining if the requested data comprises a media file; selecting a communication medium for downloading the requested data in accordance with whether the requested data comprises a media file; and downloading the requested data to the mobile communication device using the selected communication medium.
1. A method for downloading data from a content source to a mobile communication device, the mobile communication device being configured for connecting to at least cellular data networks and wireless local area networks (WLANs), the method comprising:
receiving a request to download an HTML (HyperText Markup Language) document;
determining whether the HTML document includes any embedded objects;
if the HTML document includes an embedded object:
determining whether the size of the embedded object is greater than or equal to a predetermined threshold;
selecting a communication medium for downloading the embedded object in accordance with whether the size of the embedded object is greater than or equal to the predetermined threshold; and
downloading the embedded object to the mobile communication device using the selected communication medium,
wherein the determining whether the size of the embedded object is greater than or equal to the predetermined threshold comprises:
determining by a proxy server for accessing the HTML document from the content source the size of the embedded object;
generating by the proxy server a modified HTML document including data length attribute in an object tag, the data length attribute providing the size of the embedded object in the HTML document;
transmitting the modified HTML document to the mobile communication device;
receiving the modified HTML document on the mobile communication device; and
determining on the mobile communication device if the data length attribute is greater than or equal to the predetermined threshold.
2. The method of claim 1 , wherein the determining whether the size of the embedded object is greater than or equal to the predetermined threshold further comprises downloading the HTML document without the embedded object.
3. The method of claim 1 , further comprising:
if the HTML document does not include an embedded object, downloading the HTML document to the mobile communication device using any communication medium.
4. The method of claim 1 , wherein the determining, selecting, and downloading operations are performed for each embedded object in the HTML document.
5. The method of claim 1 , wherein the determining whether the size of the embedded object is greater than or equal to a predetermined threshold comprises:
identifying a data length attribute associated with the embedded object in an object tag of the HTML document; and
determining if the data length attribute is greater than or equal to the predetermined threshold.
6. A method for downloading data from a content source to a mobile communication device, the mobile communication device being configured for connecting to at least cellular data networks and wireless local area networks (WLANs), the method comprising:
receiving a request to download an HTML (HyperText Markup Language) document;
determining whether the HTML document includes any embedded objects;
if the HTML document includes an embedded object:
determining whether the size of the embedded object is greater than or equal to a predetermined threshold;
selecting a communication medium for downloading the embedded object in accordance with whether the size of the embedded object is greater than or equal to the predetermined threshold; and
downloading the embedded object to the mobile communication device using the selected communication medium,
wherein the determining whether the size of the embedded object is greater than or equal to the predetermined threshold comprises:
requesting an Hypertext Transfer Protocol (HTTP) header of the embedded object; and
determining if a content-length header in the HTTP header is greater than or equal to a predetermined threshold.
7. The method of claim 6 , wherein the determining whether the size of the embedded object is greater than or equal to the predetermined threshold further comprises:
determining by a proxy server for accessing the HTML document from the content source the size of the embedded object;
generating by the proxy server a modified HTML document including a content-length header of the HTTP header, the content-length header of the HTTP header providing the size of the embedded object;
transmitting the modified HTML document to the mobile communication device;
receiving the modified HTML document on the mobile communication device; and
determining on the mobile communication device if the content-length header in the HTTP header is greater than or equal to a predetermined threshold.
