The exchange, as well as the use and nature, of sensitive information released can be governed by one or more privacy agreements established between the principle parties, namely, a client device and a content server. A proxy server can be used to establish privacy agreements with content servers (service providers).

Abstract: Access to hypermedia servers connected to networks such as the Internet can be provided through mobile devices such as wireless telephones. Hypermedia links such as Uniform Resource Locators (URL) are used to identify and control access to resources on the network. These links are usually very long, are difficult to remember, and are difficult to enter into many mobile devices. These difficulties could be overcome by storing lists of frequently used links or “bookmarks” in the mobile device but limited memory in the device generally prevents this. This limitation is overcome by storing designated hypermedia links on a bookmark server. In one embodiment, the URL of the bookmark server is sent to the mobile device during initialization of the device. By allowing a user can to save, retrieve and maintain lists of frequently used links on the bookmark server, access to favorite resources on a network is greatly simplified.

Abstract: Techniques for controlling a network connection in accordance with connection information associated with a destination location on a network are disclosed. Controlling of the network connection in accordance with connection information associated with the destination location can be achieved in a variety of ways. One way is in the selection of a network transport (e.g., bearer selection). Another way is in the configuration of parameters associated with the connection (i.e., connection parameters). In either case, the connection information includes information with which the selection of the network transport and/or connection parameters can be made. The controlling of the network connection impacts quality of service provided to a requestor that is requesting use of the connection.

Abstract: A method and apparatus for establishing a secure tunnel through a proxy between a user device and a secure server on a network are described. The method comprises storing information retrievable by the proxy server, in the event of the user device sending a request to the proxy server to access the secure server during a current session with the proxy server. The information indicates that the user device wishes to access the secure server. Thereafter, the current session between the user device and the proxy server is terminated. A tunnel is set through the proxy server between the user device and the secure server (via a trusted domain proxy/firewall) in the event of the user device sending a further request to the proxy server to access the secure server.

Abstract: Improved techniques for reducing delays faced by users of mobile devices due to unavailability of wireless networks are disclosed. The techniques facilitate the reduction of delays faced by users of mobile devices during unavailability of wireless networks. A first technique allows mobile devices to communicate with remote servers using asynchronous communications, namely asynchronous requests. Such asynchronous communications allow the processing at a mobile device to continue while the asynchronous request is processed in the background. A second technique pertains to the use of content channels with mobile devices. The content channels are stored and retained in cache memory so that their resources are guaranteed to be locally available, regardless of availability of wireless networks. A third technique pertains to improved list processing within mobile devices such that lists can be manipulated without server interaction. These various techniques can be used separately or in combination.

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: 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 “pulled” 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.

The user of the device is then presented with a plurality of input and choice screens, which may be used in conjunction with the user interface to provide user information, select device features and services. The user information and selected feature and service requests are then forwarded to the provisioning server device. The provisioning server device processes the received information and generates provisioning packages, registration requests, and notifications for the subject mobile device and for any associated server device providing services. The provisioning packages may comprise software modules, parameters and any required security information.

Abstract: A credential caching proxy server that handles credential caching for a set of wireless client devices is disclosed. The credential caching proxy server handles most credential transactions for wireless client devices that wish to access resources within a protected realm where the protected realm requires credentials. In one embodiment, the credential caching proxy server intercepts and caches a wireless client's credentials when a credential is first sent from the wireless user agent to a protected server. The cached credential will then be used for all requests to resources within the same protected realm. Thus, after first sending a first credential for accessing the resource in a particular realm, the wireless user agent does not need to attach the credential for all the subsequent requests for any other resources belong to the same realm. In an alternate embodiment, the proxy server sends a special request to the wireless client device requesting a credential for a particular resource.

Abstract: A gateway routes signals between a WAP mobile phone and an application on a Web server. The application generates a message for each of a number of events recognized according to the service being provided. These messages are transmitted to the gateway. A billing manager in the gateway directs the messages in real time to a real time mediation device if they relate to a pre-pay service, or alternatively to a billing log for off-line processing. The network operator operating the gateway can thus charge in a manner relating to services provided instead of simply call duration.

Abstract: A wireless communication system that utilizes a remote voice recognition server system to translate voice input received from serviced mobile devices into a symbolic data file (e.g. alpha-numeric or control characters) that can be processed by the mobile devices. The translation process begins by establishing a voice communication channel between the serviced mobile device and the voice recognition server. A user of the mobile device then begins speaking in a fashion that may be detected by the voice recognition server system. Upon detecting the user's speech, the voice recognition server system translates the speech into a symbolic data file, which is then forwarded to the user through a separate data communication channel. The user, upon receiving the symbolic data file at the mobile device, reviews and edits the content and further utilizes the file as desired.
