Can i use this UDP to send Wap Push to students? How?
nop, in general not. WAP Push via IPv4 is from the WAP protocol stack
"possible". But telcos usually don't allow IP traffic from the "outside" world
to their GPRS IP range. So you won't be able to send UDP packets from your WWW
server to the mobile devices. You will have to "notify" the mobile devices via
WAP Push via SMS.
You'll need to connect your "MMS sending server" via a GPRS/GSM modem to the
telco and send via that channel to the operator's MMSC.
When a student sends the first message to my mmsc, can i get his/her IP out
from mbuni easily ( I found that it is written
to logs ) and use it to send messages (Wap Push)
do they use a Kannel WAP GW that is installed on your side? Or are they directly
sending via HTTP to mbuni?
If they go via WAP GW, then you "won't" see the client IP (hence the mobile IP)
for that time, but Kannel's WAP GW client IP
.
to student? Then student must of course keep GPRS-connection open whole
learningsession, because IP is changing between
connections.
you can try if you can send WAP Push datagrams via IPv4 to the mobile connected
devices. It _MAY_ be that your telcos passed the UDP datagrams, but in general
they cover their GPRS IP space via firewalls... which telco is used?
Code of my environment will be published with GPL - license and maybe it is
useful also
good idea ;)
We'll try to assist as far as possible.
