Abstract

A messaging proxy system is disclosed for the purpose of delivering data in the form of a portable message format from a producer running on a mobile or non-mobile computer, over any wireless network, by passing this data through an intermediary proxy computer program, to one or more recipients running on mobile or non-mobile computers. The system includes a message proxy computer program with at least one pluggable transport protocol adapter. The proxy contains a command subsystem for sending and receiving command- and message-tokens to and from the mobile clients. The system further includes a thin messaging middleware client to run on mobile devices. The thin messaging middleware client includes at least one pluggable protocol adapter. The client also comprises a command subsystem for sending and receiving command- and message-tokens to and from the proxy. The proxy also contains a communication subsystem for sending and receiving messages via a state of the art message oriented middleware.

Claims

1. A system for delivering information between applications running on mobile wireless devices and serving as clients and applications running on computers, said computers being connected to a wired computer network, the system comprising

a message proxy implemented on a computer connected to the wired computer network, and wireless communication means for establishing a communication channel between the message proxy and the clients,

the clients each comprising a programming library corresponding to at least a fraction of a programming library used by a message oriented middleware (MOM) and a transport protocol adapter with a logic to interface with a transport protocol, thus defining at least one communication transport protocol for a communication on said communication channel,

the message proxy comprising at least one transport protocol adapter with a logic to interface with said communication transport protocol,

the system further comprising:

means for creating, on each wireless device, code information representing at least one of a topic and of queue contained in a MOM programming library,

means for transmitting, from each client, via the transport protocol adapter, the code information to the message proxy implemented on a computer connected to the wired computer network,

means for simultaneously or subsequently, transmitting, from each client, via the transport protocol adapter, message data specific to a first application to the message proxy, and

means for creating, by the message proxy, at least one MOM command referred to by the code information, and

means for forwarding the message data to a second application using the MOM command referred to by the code information.

2. The system of claim 1, whereby the message proxy comprises at least one of a wireless transport protocol adapter implemented before start-up of the message proxy and of a wireless transport protocol adapter implemented by a program code at run-time of the message proxy.

3. The system of claim 1, whereby said at least one transport protocol adapter supports HTTP (Hypertext Transfer Protocol) or SMS (Short Messaging Service) or WAP (Wireless Application Protocol) or WDP (WAP Wireless Datagram Protocol) or GPRS (General Packet Radio Services) or UMTS (Universal Mobile Telecommunications Service).

4. The system of claim 1, whereby a local database is provided on at least one of the clients and on the message proxy, allowing the client and the message proxy to store information in case of disconnection.

5. The system of claim 4, whereby at least one pluggable database adapter is provided allowing the client and the message proxy to use any database product.

6. The system of claim 1, whereby the clients are implemented in the JAVA programming language.

7. The system according of claim 1, whereby the clients are implemented according to the JMS (Java Message Service) specification.

8. The system of claim 1, whereby the clients support the JMS publish/subscribe messaging model.

9. The system of claim 1, whereby said clients support the JMS (Java Message Service) point-to-point messaging model.

10. A method of delivering information between a first application running on a mobile wireless device and serving as client and a second application running on a computer, the computer being connected to a wired computer network, comprising the steps of,

providing, as part of the client, a programming library corresponding to at least a fraction of a programming library used by a message oriented middleware (MOM) and a transport protocol adapter with a logic to interface with a transport protocol,

creating, on the wireless device, code information representing at least one of a topic and of queue contained in a MOM programming library,

transmitting, from the client, via the transport protocol adapter, the code information to a message proxy implemented on a computer connected to the wired computer network,

simultaneously or subsequently, transmitting, from the client, via the transport protocol adapter, message data specific to the first application to the message proxy, and

creating, by the message proxy, at least one MOM command referred to by the code information, and

forwarding the message data to the second application using the MOM command referred to by the code information.

11. A computer program for being run on a computer connected to a wired computer network, comprising program code means for implementing

at least one transport protocol adapter with a logic to interface with a transport protocol, means for receiving at least one of message oriented middleware (MOM) command tokens and of MOM message tokens from an application running on a mobile wireless device serving as client, via said transport protocol adapter and using said transport protocol,

means for sending MOM message tokens to a client via said transport protocol adapter and using said transport protocol, and

means for exchanging MOM message tokens with a MOM client implemented on a computer of said wired computer network, and
