Abstract:
A link infrastructure (120) receives a notification via the Internet (104) from a web server device (112) when specific information is updated at the web server device. The specific information is subscribed by a client device (106) and identified by the notification which comprises a subscriber identifier identifying a user account corresponding to the client device. A client device identifier with respect to the subscriber identifier in the notification is obtained and a corresponding message including the notification is sent from the link infrastructure to the client device identified by the client device identifier via a narrowband channel. Thus, 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:
The present invention relates to navigation of the Internet by a two-way interactive communication mobile device capable of wireless communication, via a link server (300), with service providers or network servers on the Internet. After the mobile device has established a communication session with the link server over a wireless network (308), a control engine 320 in the link server is initiated and uses the computing resources of the link server device so as to be responsible for tasks that require considerable computing power and memory. such as processing of URL requests, interpretation of markup language files, management of data cache and variable states. Working with a message processor (315) in the server device, the control engine communicates with an interface engine in the mobile device using a compact data format that is efficiently transportable in the wireless data network. The interface engine typically performs tasks that do not require considerable computing power and memory, such as receiving input data from users, and the rendering of the compact data format received from the link server device, to cause the mobile device to display contents in the markup language files on a display screen.

Abstract:
A communication system (200) has a plurality of wireless communication devices (202, 204, 206) coupled through a plurality of wireless network carriers (208, 210, 212) providing wireless communication services thereto using a different combination of network type and transport protocol. A multi-network gateway (214) couples the wireless network carriers to a network of computers (216, 218, 220) containing information therein to facilitate data transfer therebetween. The wireless network carriers are coupled to the network of computers by an airlink configured for the particular combination of network type and protocol, and each of the airlinks operate to exchange data with certain of the wireless communication devices via the wireless network carriers associated therewith.
