Method and system for integrating narrowband and wideband channels

摘要

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.
