Abstract: The invention allows access to the Internet by two-way mobile communication devices capable of wireless communication via a link server. Despite limited computing resources in the mobile devices, the invention allows the mobile devices to interact with Internet entities using a control engine in the link server and an interface engine in the mobile devices. The control engine utilizes the computing resources of the link server and handles tasks requiring considerable computing resources, such as processing of URL requests, interpreting markup language files, managing a data cache and variable states. Working with a message processor in the link server, the control engine communicates with an interface engine 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 resources, such as receiving input from users and rendering data received from the link server.

Abstract: A system configured to manage and process service requests within a data network. The system comprises a link server device that is configured to receive a service request from an interactive communication device, wherein the link server device attaches link server information to the service request indicating the operational capabilities of the link server device. A server device configured to receive the service request from the link server device and supply a service request response based upon information in the service request and the link server information. Wherein the link server executes a service command upon receipt of the service request response and supplies a status response to the interactive communication device.

Abstract: The present invention is particularly applicable to navigation of Internet by two-way interactive communication mobile devices that are capable of wireless communication via a link server with service providers or network servers on the Internet. Despite the limited computing resources in mobile devices that make it economically and technically impractical for the mobile devices to operate a local browser functioning as if it was in a desktop computer, the present invention allows the mobile devices to interact effectively with the Internet using a control engine operating in the link server and an interface engine operating in the mobile devices. The control engine, which utilizes the computing resources of the link server device, is 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.

Abstract: To accept, store, and use dynamic information within a markup language, a markup language variable system is introduced. The markup language variable system allows variable scopes to be created within markup language user agents. Variables can then be assigned using static variable assignment via markup language tags or dynamic variable assignment via user requests. Variables can be used within markup language displays or within addresses such as Uniform Resource Locators (URLs). Automatic escaping ensures that variables are correctly modified for use within certain contexts such as URLs.
