A computer system provides content to a client device such as a handheld wireless telephone by identifying the client device as a limited-display client device, receiving a request from the client device for hypertext content (e.g. content in HTML form), and generating a reduced-size version of the requested hypertext content. Based on the identification of the client device as a limited-display client device and in response to the request, the reduced-size version of the hypertext content is returned to the client device. The reduced-size version of the hypertext content may be generated by removing information from the hypertext content which is not relevant to the display of the client device, and the reduced-size version of the hypertext content may include page in a text-based hypertext markup language such as HTML. A layout conversion may be used from a first hypertext layout to a second hypertext layout of the reduced hypertext content, which may be more directly usable by a handheld wireless telephone than is the first hypertext layout.

Method and system for providing reduced-size hypertext content to a limited-display client device

A method and system are provided for transmitting information from a faster network to a data terminal via a slower network connection. The invention is adapted for use with any Internet access device or terminal, such as an Internet-compatible telephone. A client connects to the Internet via an intermediary software program, known as the Gateway (GW). In the preferred embodiment of the invention, the GW executes on a host computer of an ISP's Local Area Network (LAN). The GW thus mediates the data transfer between the Internet, such as the Web and the client Internet terminal. The GW employs a point-to-point Internet protocol, the Gateway interface Protocol (GWIP) to communicate with the client over the low-bandwidth link. The invention shifts the entire overhead of the Internet protocol stack to the GW, and does not involve the Internet terminal or the slow link between Internet terminal and GW. The GW makes and negotiates multiple Internet requests, in parallel, and multiplexes the resulting data streams, allowing documents to be loaded in parallel with their associated images. The GW may also be used to conveniently customize or upgrade the Internet terminal. The GW performs off-line services and caches commonly used information fetched from the Internet. The invention is also readily adapted for use with Internet access devices that require different document formats.
