J2ME PHP Push Notification

<b>I want to work on a project which has to do with the server sending notification to the client. The client side is a j2me application and the server side script will be implemented using php.

I have found out i can use the push registry API in midp 2.0 for push notifications, but i don't know how to implement this such that a socket connection will be created to the server such that notification can be sent to the client via the socket connection. The notifiation will then trigger the start of the midlet.

How can i use the push api to create a socket connection between client and server and have notifications sent to the client?

Thanks in advance.</b>
