Abstract

A system, apparatus and method for enabling interaction between a mobile device and a dynamic list of remotely hosted applications. A mobile device is provided with a removable module implementing a virtual machine defined by a set of instructions. The mobile device requests an initial application from an application server. The application server generates a message, including a set of commands and any parametric information, such as text to be displayed, which is then compiled into executable code. The executable code is then forwarded to the mobile device for execution. The mobile device interprets the executable code and runs it, possibly causing text or a menu to be displayed. In a first embodiment, the mobile device requests a list of currently available applications and is provided with such a list by a first application server. The user is then able to select from the list of applications, some which can be located on other servers. In another embodiment, an application server initiates a communication by transmitting a set of commands causing one or more actions on the mobile device, such as the sounding of an audio alarm, the displaying of text, etc.

Claims

1. A mobile terminal system, comprising:

at least one mobile device for communication with at least one application server via a communication medium, said mobile devices having a user interface, a wireless communications interface and a removable module removably attached to said mobile device via an input/output interface on said removable module;

a virtual machine implemented by said removable module, said virtual machine defined by a set of instructions enabling management of said mobile device;

said removable module additionally having a wireless communication module enabling said virtual machine to receive a set of commands through said wireless communications interface from said at least one application server, said commands being chosen from said set of instructions; and

at least one application hosted by said at least one application server, said at least one application having a first network interface for sending said set of commands and receiving a set of client data.

2. The mobile terminal system of claim 1, wherein said removable module and said at least one application server additionally comprise a cryptographic module to provide authentication between said mobile device and said at least one application server.

3. The mobile terminal system of claim 2, wherein said cryptographic module encrypts and decrypts communication between said mobile device and said at least one application server.

4. The mobile terminal system of claim 2, additionally comprising:

at least one certificate server able to receive a request for a digital certificate of one of said at least one application server and respond with said digital certificate, such that mobile device is able to obtain said digital certificate.

5. The mobile terminal system of claim 4, wherein said at least one certificate server is able to receive a request for validation of a cached digital certificate stored on said mobile device and provide an updated digital certificate or a notification that said cached digital certificate could not be validated.

6. The mobile terminal system of claim 5, wherein said digital certificate for said at least one application server is transmitted by an OTA server to said mobile device.

7. The mobile terminal system of claim 1, additionally comprising:

a gateway with a second network interface for sending and receiving a set of communications to and from said mobile device, a third network interface for sending and receiving said set of communications to and from said at least one application server and processing means to reformat said set of communications between a first protocol handled by said wireless communication interface of said mobile device and a second protocol handled by said first network interface of said application server.

8. The mobile terminal system of claim 7, wherein said first protocol is SMPP.

9. The mobile terminal system of claim 7, wherein said second protocol is TCP/IP.

10. The mobile terminal system of claim 1, additionally comprising:

a first application server hosting a directory application, said directory application being configured to provide an application list response to said mobile device in response to an application list request from said mobile device, enabling said mobile device to initiate interaction with one of said at least one application.

11. The mobile terminal system of claim 10, wherein said first application server has knowledge of at least one other application hosted by at least one other application server, and said application list response includes a set of addresses for said at least other one application hosted on said at least one other application server.

12. The mobile terminal system of claim 1, wherein said mobile device is a GSM Phase II+-compatible device and said removable module is a subscriber identity module.

13. The mobile terminal system of claim 1, wherein said removable module is a universal subscriber identity module.

14. The mobile terminal system of claim 1, wherein said set of instructions consists of one byte op-codes.

15. The mobile terminal system of claim 1, wherein said virtual machine is implemented in an application specific integrated circuit on said module.

16. The mobile terminal system of claim 1, wherein said at least one application server is in communication with at least one data server and one of said applications on said at least one application server is operable to request and receive a data object from said at least one information server, reformat said data object for said virtual machine and transmit said reformatted data object to said mobile device.

17. The mobile terminal system of claim 16, wherein said data object is a web page.

18. The mobile terminal system of claim 16, wherein said data server is a database server.

19. A mobile terminal device, comprising:

a mobile device having a user interface, a removable module removably attached to said mobile device via an input/output interface on said removable module and a wireless communications interface for communicating with at least one application server;

said removable module implementing a virtual machine enabling management of said mobile device through a set of instructions provisioned by said virtual machine; and

a wireless communication module on said removable module enabling said virtual machine to transmit a set of client data through said wireless communications interface to said at least one application server and receive at least one command formed from said set of instructions.

20. A removable module for use in a mobile device, comprising:

an input/output interface on said removable module operative to removably attach said removable module to said mobile device;

non-volatile memory means for storage of at least one application and a set of application data; and

said at least one application including a virtual machine defined by a set of instructions, and a communications module enabling said mobile device to receive a message in a first format natively handled by said mobile device and allowing the extraction from said message at least one command at least partially comprised of a subset of said set of instructions,

such that said mobile device is able to receive said at least one command from an application server.
