Mobile message type specification - WAP Push SMS
(SMS message type, SMS message format)

Introduction

The WAP Push technology makes it possible to send a specially encoded SMS message with a description and link to a WAP address (URL). When a GSM handset receives this WAP Push message, it will automatically give the user the option to access the WAP content. The WAP content can be a WML page, a JAVA application or multimedia content.
WAP Push is also used to send polyphonic ringtones and wallpaper images to phones.
To instruct a phone to go to a certain WAP location, a Service Indication message needs to be used. This is an XML document that contains a URL for the handset to browse to.

Why it is convenient

A WAP Push message is more convenient than a simple text message, because the recipient only receives the text of the link in a simple text message, which then has to be entered into the browser manually. However, if the recipient receives the URL in a Wap Push message, it only takes one or two clicks to open the respective page.

Message type

SMS:WAPPUSH

The format of the message data is:

<si>
    <indication href="..." action="...">
        ...
    </indication>
</si>

Example WAP push message format:

<si>
    <indication href="http://wap.origo.hu/" action="signal-high">
        A WAP Push to the Origo site
    </indication>
</si>

Action can be: signal-high, signal-medium, signal-low, signal-none, signal-delete

Sending a WAP Push message from an SQL database

If you use the SQL to SMS gateway configuration to send and receive SMS messages from your database, you can use the following SQL statement to send a WAP PUSH Service Indication message:

insert into ozekimessageout (receiver,msgtype,msg,status) values ('+36205222245',
         'SMS:WAPPUSH:application/vnd.wap.sic','<si><indication href="http://wap.origo.hu/"
         action="signal-high">A WAP Push to the Origo site</indication></si>','send');
