What is the best way to achieve push on CLDC devices?

Question

I would like to receive push messages from a server on most CLDC mobile phones while my application is running in background.

I did it already with SMS but it is costly so I'm thinking about another solution...

I know I can poll my server with HTTP requests. Simple polling should be easy to implement. However, I don't have many updates to send (~5 per hours) but I need them to arrive on the device quickly (~1 minute).

Long polling is great but I think I will have to handle timeouts, disconnects... While with socket I don't have the timeout problem, right?

So,

• Is there a simple solution/library to implement push ?
• Does keeping the connection alive has other problems : over-consumption of the battery, operator's firewall restriction... ?

Thanks
