A proxy gateway is coupled to one or more wireless hand-held devices over a wireless network and to one or more origin servers over a wired network. The proxy gateway proxies requests and responses between the wireless devices and the origin servers. The proxy gateway determines when private information associated with a wireless device is needed or requested by another network entity, such as an origin server. In response to such determination, the proxy gateway communicates with the wireless device to enable the wireless device to present a user interface which allows a user of the wireless device to dynamically control release of the private information.

Method and apparatus for dynamically controlling release of private information over a network from a wireless device

A secure push server is disclosed. The push server is used for sending notifications to different wireless clients on different wireless networks. The push server allows information service providers to send notifications to the wireless clients. The information service providers initiate a request to the push server that includes updated information. The request also includes a certificate from the information service provider. The push server authenticates the request from the information service provider by verifying the certificate. The push server also determines if the certificate was issued from an acceptable certificate authority by examining an acceptable certificate authority list. Finally, the push server checks the content of the notification to be sure it does not interfere with other information service providers. After performing the security checks, the push server processes the notification request.

A unified interface is disclosed for sending update notifications to different wireless clients on different wireless networks. The update notifications may be push notifications or pull notifications. Push notifications include a data payload with updated information. Pull notifications merely specify an address where update information is available. The updated information must be &ldquo;pulled&rdquo; using the supplied address. Several maintenance requests are provided for querying notification status, deleting individual notifications, and clearing all notifications addressed to a particular subscriber.

Method and apparatus for informing wireless clients about updated information

The present invention discloses a centralized certificate management system for thin client devices in data networks and has particular applications to systems having a large number of the thin clients serviced by a proxy server through which the thin clients communicate with a plurality of secure server computers over a data network. According to one aspect, the present invention comprises a certificate management module that causes the server device to manage digital certificates for each of the thin client devices. To minimize the latency of obtaining certificates for each of the thin client devices, the certificate management module reserves a fixed number of free certificates signed by a certificate authority and their respective private keys in a certificate database and frequently updates the free certificate according to a certificate updating message. Whenever a user account is created for a thin client device, the certificate management module fetches one or more free certificates from the certificate database and associate the fetched certificates to the created account and meanwhile the certificate management module creates new free certificates with the certificate authority to fill in the certificate database. Apart from the tradition of obtaining certificates locally in client devices that normally have sufficient computing power, the present invention uses the computing resources in a server device to carry out the task of obtaining and maintaining certificates asynchronously in the proxy server and further. These and other features in the present invention dramatically minimize the demands for computing power and memory in thin client devices like mobile devices, cellular phones, landline telephones or Internet appliance controllers.

Centralized certificate management system for two-way interactive communication devices in data networks

Techniques for routing messages to addressable portions (e.g., processes) within an apparatus are disclosed. The techniques can be performed by a variety of apparatus including, for example, a gateway, a proxy server or a mobile device. After receiving the messages routed thereto, the addressable portions are able to process the messages and perhaps return a reply message. Often, the apparatus is a gateway or proxy server coupled between a network containing remote computers storing information and a wireless communication system including a plurality of mobile devices. The processing of the message will typically act to produce a message that forwards certain of the information from one or more of the remote computers on the network to a mobile device coupled to the wireless communication system.

The invention relates to centralized network access for wireless network carriers providing network access to wireless communication devices. The invention provides a network gateway (or proxy server) that provides access to a network of computers to various wireless network carriers having different wireless network characteristics. In one embodiment, the invention uses airlinks (or network drivers) to support the communications between the network gateway and the various wireless network carriers.

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. Hence systemic solutions are provided in the present invention to integrate wideband and narrowband channels so as to keep the users informed of any updates to their desired information and meanwhile provide efficient means to the users for retrieving the latest updates without incurring uncontrollable costs and increasing unnecessary network traffics.
