GPRS, Sorry I didn’t see your reply.
“4. After refresh, browser displays missing image ——–> is this case, the MFS will establish another DL TBF to send the missing part of the web page?? or it will use the first established DL TBF?????
”
The DL TBF will be released after there is no more data to send. It is kept alive for few seconds, so in case of a missing image, it’s very probable the same DL TBF will be re-used to transmit it. However it depends how long the webserver took to actually detect missing image and decide to resend it.
But anyway, I think you got the idea of how it works 🙂
Cheers
