This guide gives you information on how to send MMS replies to incoming
SMS messages automatically. The solution presented can be used to send
a brochure containing pictures to a cellphone if a keyword is received from it
in an SMS message. In this solution the MMS response is stored in a MySQL database
and the MMS picture attachments are stored in the file system.
To setup a service, where you receive SMS messages and you send MMS responses
you need two connections to the mobile network. One connection will be used
to receive the SMS messages, the other will be used to send the MMS reply back.
The SMS Connection can use an IP SMS service provider through the SMPP protocol.
The MMS connection can use the MM7 protocol to send MMS messages over the
Internet to an MMS service provider. The automatic response can be generated by
the Autoreply database option of Ozeki NG SMS Gateway (Figure 1).
To setup this solution, we recommend you to install a MySQL database server and
a MyODBC database driver. To connect to the MySQL databse server, you need to
configure the following connection string in the "Autoreply database" user of
Ozeki NG SMS Gateway:
After the database table has been created, please insert a test record
into it using the following SQL command:
INSERT INTO keywordresponse (messagetype, messagetext, keyword)
'Deart customer!This color is the perfect choice for you if you
want to get in the center of attention!ononhighpersonalc:\tmp\pink.gifc:\tmp\pink.mp3',
Autoreply database script
After the database has been setup, you need to create the Autoreply database script.
You should include the following SQL query in this script:
SELECT '$sender', messagetext, messagetype FROM keywordresponse WHERE keyword='$keyword'
Note that this query includes a messagetype column.
