Abstract: The present invention has particular applications to the navigation of Internet web pages using two-way interactive communication devices, such as a mobile device, a mobile phone, a landline telephone, and an Internet capable remote controller. According to one aspect of the present invention, each of the two-way interactive communication devices is a node in a distributed network, thus the devices can access hypermedia or hierarchic layers of information stored in server devices on the network. When one or more pages of information are updated, rather than sending the entire updated information to users of the devices subscribing to the updated information through the network, the present invention sends a notification to a proxy server that forwards the notification to the users using a messaging system via a low cost narrowband channel. Upon receiving the notification, the users can fetch the updates, when needed, through a wideband channel.

Abstract: Under the limited bandwidth of the current wireless data network and with the low memory in mobile devices in use today, the process of going through a number of intermediate pages to get to a desired page increases the latency of the information deliver and intensifies the network traffic. A method for accelerating the navigation of hypertext pages based on a compound request is disclosed. After a compound request is entered and activated, the compound request is parsed into an antecedent request followed by a final request wherein the antecedent request comprises a plurality of intermediate requests. All the intermediate requests are processed individually and sequentially as if they were entered individually and cards corresponding to the intermediate requests are fetched sequentially. A final card containing desired information by the final request is fetched based on the card corresponding to the last intermediate request and thereby displayed.

Abstract: Data are pushed from a source to a destination via an intermediate computer system. If the intermediate computer system is unable to forward the pushed data to the destination for a predetermined length of time, the intermediate system deletes the pushed data and never forwards the data to the destination. According to another aspect, the intermediate system receives a command, e.g. from a server originating the data, to delete the data if the data has not yet been forwarded to the destination. According to another aspect, the intermediate system receives data whose identifier (e.g. source URL) matches an identifier of data pushed earlier to the same destination but not yet forwarded. The intermediate system deletes the earlier pushed data and never forwards the earlier pushed data.

Abstract: The present invention has been made in consideration of thin devices efficiently communicating ideas and transactions into data networks by using other devices with full functional user interface in the networks. According to one aspect of the present invention, the thin device exclusively controls the authentication of a rendezvous that is associated with a user account in a server. The thin device running a micro-browser provisions the rendezvous with a set of credential information in an authenticated and secure communication session so that the provisioning process is truly proprietary. To access the user account, the other devices equipped with well known browsers must submit the correct credential information to the rendezvous for verification in the server.
