[WAP Push] Sending SI (Service Indication) via SMS

[wongkaho]

Hello All,

there have a few posts already regarding how to construct an SI short message.
i also would like to do the same thing, and i've did my little silly hack. here
are the my references:

WAP Push

WBXML

http://www.devx.com/xml/articles/bs120101/Part2/bs120101p2-1.asp

i'm so lucky that i found that the Nokia phones have not problem to recognize
my SI.

however, dunno why, it didn't work on other phones, like the SonyEriccson, LG.

any idea?

Hi!

I'm sorry, but at least I as a "nokian" don't know what could be wrong with other terminals. Have you tried searching information from their sites? We have this one guide in Forum Nokia called Getting started with WAP Push (under Technologies/Browsing/Documents). Have you read that?

I tried sending ur Binary SI to SMSC,but i m not not receiving anything from SMSC.
So my question is IF I SEND SI IN WBXML TO SMSC,WILL i receive the wap push message or now??
n Is WBXML meant for PPG(push proxy Gateway) or we can directly send the WBXML(in binary after encoding in WSP) message to SMSC???
