Abstract

A mobile-terminal platform system having an application subsystem and an access subsystem. The access subsystem includes hardware and software for providing connectivity services. The application subsystem includes hardware and software for providing user application services. The application subsystem and the access subsystem communicate via a defined interface. Each of the application subsystem and the access subsystem are adapted to be independently scaled.

Claims

1. A mobile-terminal platform system comprising:

an application subsystem comprising hardware and software for providing user application services, further comprising

an interface service stack wherein the interface service stack is configured to permit the application subsystem to communicate with the access subsystem;

an operation service stack, wherein the operation service stack is configured to provide system control, system data handling, component management, and proxy management;

an application-platform service stack, wherein the application-platform service is adapted to provide at least one of Short Message Service (SMS) cell broadcast service, phone book service, platform accessory services, clock service, and positioning application service;

a man-machine interface and multimedia stack, wherein the man-machine interface and multimedia stack is configured to provide at least one of user interface services, audio services and control, voice control services, graphics services, image services, camera services, and video services; and

a multimedia protocol stack, wherein the multimedia protocol stack is configured to provide application protocol services;

an access subsystem comprising hardware and software for providing connectivity services;

wherein the application subsystem and the access subsystem communicate via a defined interface; and

wherein each of the application subsystem and the access subsystem are independently scaled and wherein the application subsystem and the access subsystem operate on different clocks.

2. The mobile-terminal platform system of claim 1, wherein the application subsystem comprises a middleware adapted to allow application developers to access the application subsystem and the access subsystem.

3. The mobile-terminal platform system of claim 1, wherein scaling of the application subsystem does not decrease functionality of the access subsystem.

4. The mobile-terminal platform system of claim 1, wherein scaling of the access subsystem does not decrease functionality of the application subsystem.

5. The mobile-terminal platform system of claim 1, wherein access to the mobile-terminal platform system may only be made via the middleware.

6. The mobile-terminal platform system of claim 1, wherein an access subsystem clock is more accurate than an application subsystem clock.

7. The mobile-terminal platform system of claim 1, wherein:

the communication-standard service stack is configured to operate according to at least one wireless-communication standard;

the data-communications service stack is configured to provide at least one of sockets services and communication-port services;

the basic service stack is configured to provide general access services; and

the interface service stack is configured to permit the access subsystem to communicate with the application subsystem.

8. The mobile-terminal platform system of claim 1, wherein the at least one wireless-communication standard comprises at least one of Global System for Mobile Communications (GSM), General Packet Radio System (GPRS), Enhanced Data Rates for GSM Evolution (EDGE) and Wideband Code Division Multiplexing Access (WCDMA).

9. The mobile-terminal platform system of claim 1, wherein the application protocol services comprise multimedia protocol services, wireless application protocol (WAP) services, object exchange OBEX protocol services, and BLUETOOTH application services.

10. The mobile-terminal platform system of claim 1, wherein the access subsystem is configured to be used in a stand-alone mode.
