Abstract

The disclosed invention comprises a system and method for providing two-way content communication between wireless mobile communication devices, such as pagers and Personal Information Managers, and a remote computer network such as the Internet. The system includes a wireless two-way messaging network and an intermediary computer network in communication with the remote computer network. The wireless two-way messaging network employs a network and layer framework, preferably programmed in the wireless mobile device, that includes a system layer, an operating system layer, a user interface, and a Message Transport Protocol (MTP) stack.

The method for providing two-way content communication between wireless mobile communication devices and a remote computer network include originating a data request at the mobile communication device, transmitting the request via a queue to the intermediary computer system, retrieving the requested data from the remote computer system, and transmitting the retrieved data to the wireless mobile communication device via the wireless two-way messaging network. In the preferred embodiment, the retrieved data is transformed to an intermediary markup language, preferably Extensible Markup Language (XML), validated for MTP coding and transmission completeness, analyzed for type of data, and transformed to a target markup language. The validated, analyzed and transformed data is subsequently displayed at the mobile communication device in a suitable form, which in a preferred embodiment is a browser with a graphical user interface.

Data encryption and decryption is available for all data transmission in the present invention, and the system and method include means for placing all transmitted data into packets of maximum 448 characters, suitable for Short Messaging Service protocol and similar protocols.

Claims

a plurality of data modules in communication with said first electronic queue;

an event handler in communication with said plurality of data modules;

an application dispatcher in communication with said plurality of data modules and said event handler;

a second electronic queue of data communicated from said intermediary computer system to said wireless two-way messaging network; and

a content fetcher in communication with said application dispatcher and said remote computer network.

6. The system of claim 5, wherein said second queue further comprises means for Message Transport Protocol encoding.

7. The system of claim 5, wherein said plurality of data modules comprises at least one of:

a message validator;

a session module;

a wireless IP/IP mapper database;

a data transformer;

an encryption module; and

a cache manager.

8. A method for providing two-way communication of content between a wireless mobile communication device and a remote computer network via an intermediary computer system, comprising the steps of:

originating a request for data at said wireless mobile communication device and transmitting said data request through a network and layer framework to a two-way wireless messaging network;

transmitting said request for data from said two-way wireless messaging network via a first electronic queue to said intermediary computer system in communication with said remote computer network;

retrieving the requested data from said remote computer network;

placing said retrieved data in a second queue;

transmitting said retrieved data from said second queue to said wireless communication device via said two-way wireless messaging network; and

displaying said retrieved data at said wireless communication device.

9. The method of claim 8, wherein said request for data is a Uniform Resource Locator.

10. The method of claim 8, wherein said wireless communication device includes a stored Wireless EP, and further wherein the step of transmitting said data request through a network and layer framework to a two-way wireless messaging network comprises the steps of:

encoding said data request into Message Transport Protocol;
