Process for communication between a device running JAVA me and a server over the air, as well as related system

Abstract

Process of communication via HTTP or HTTPS between a device running Java ME® and a server over the air, said server receiving and transmitting SOAP (Simple Object Access Protocol) messages from / to an operator on a host over a network and being capable of exchanging SOAP messages under Application Protocol Data Unit (APDU) data form / with the device, characterized in that the SOAP messages are translated from / to binary messages according to a protocol in the server, said binary messages being exchanged with the device, the binary messages being binary request messages or binary response messages.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to PCT Application PCT / IB2007 / 003716, filed Nov. 30, 2007, and EPO Application 06301199.3, filed Nov. 30, 2006, the disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a process for communication between a device running Java ME® and a server over the air, as well as related system.BACKGROUND OF THE INVENTION[0003]The current invention defines a new communication process using a Java ME (J2ME) application as a proxy between a smart card on a mobile device (whether an SIM, embedded secure element, detachable secure SD, secure MMC, or any other smart card form factor) and web based application server, which is supporting SOAP messaging, to provide greater efficiency and auto recovery functionality. This process contains a protocol allowing adaptive fragmentation of data packet, optimized message format and auto recovery functionalities for a ...

AI Technical Summary

Benefits of technology

[0031]In addition, with the introduction of save points on both the application and the gateway, the application resides on the limited device and can effectively re-send the last request message to the gateway and the gateway will be able to recover the response correctly

Problems solved by technology

Some of these devices run Java ME® application and this is usually done with limited resource in terms of memory and processing power.

Moreover, the communication technology used in the device is slow and possibly unreliable with realistic speeds up to 56 Kbps.

However, the parsing and serializing of SOAP message requires much more processing and memory than a binary message.

The transport of APDU data over time is a non-guaranteed reliable connection.

Beside that, the underlying JVM runs on the device may not properly garbage collect the resources within certain period of time, hence it may leads to the subsequent open connection operation being blocked.
