Pix, thank you very much for such a quick and detailed answer!
just some more moments – if you please:
– how does SGSN change lifetime of PDU – like router in the LAN?
– as far as i understand if we set this parameter = enable we can *save* some PDU because thanks to the process of ordering PDUs with smaller lifetime will be sent earlier than the ones with bigger lifetime? – is it right?
Thanks you very much once more
