Colour SMS User
This chapter explains how to install and configure
a Colour SMS user for SMS messaging using the graphical user interface
of the Ozeki NG - SMS Gateway software.
Ozeki NG - SMS Gateway allows, among others
(see the Users
and Applications page), the installation and configuration of a Colour
The Colour SMS protocol was developed by T-mobile
Hungary for premium rate SMS services.
It is an easy to use HTTP based SMS protocol. When a customer tries to access
a premium rate SMS service by sending an SMS to a premium rate phone number, the
SMSC transfers this message as an HTTP post request to the HTTP Server operated
by the content provider. The content provider returns a response to the HTTP
request in XML format. This response is sent as an SMS message back to the
customer. The HTTP server operated by the service provider is
Ozeki NG - SMS Gateway. This user implements this functionality (Figure 1).

Due to the nature of the HTTP protocol, it is always required
to return a response to incoming messages in a short period of time.
The Colour SMS protocol is often used with other connection methods,
such as UCP to make delayed responses to incoming messages possible.
Using a UCP connection, response messages can be sent at a later time,
which is useful if you would like to set up periodic SMS notifications,
such as weekly news service.
You can use the
graphical user interface of
Ozeki NG - SMS Gateway to install and configure any user.
To start installing and configuring a Colour SMS
user, click the Add button in the top right-hand corner of
the Users and Applications panel on the right of
the Management Console.
You can also add a user by clicking the Add user item in the Users
and applications menu (Figure 2).
Figure 2 - Adding a user
This will bring up an interface consisting of two panels.
The panel on the left contains a list of users that have been installed.
In the bar at the bottom of the page you can read how many users have been
The panel on the right contains a list of users that can be installed.
Each user in the left-hand panel is listed with a unique name
(and the user type stated in brackets).
Each user in the right-hand panel is listed with the name of
its type and a brief description of what it can be used for.
To add a Colour SMS user, click the Install link
in the respective entry in the list (Figure 3).
Figure 3 - Installing a Colour SMS user
When installing a user (type), you need to
give it a unique username. Clicking the Install link will
bring up the Colour SMS user installation panel.
Here, you need to enter a unique username in the Username field.
Once you have installed a Colour SMS user,
you can start to configure it. After you have provided a unique name
for the Colour SMS user and clicked OK, the Configuration
panel will open.
The first tab that will show up is the HTTP settings tab.
In this panel you need to specify HTTP Client settings. This information
is provided by the SMS service provider when you subscribe to the service
Figure 4 - The HTTP settings tab
In the Target URL template you can specify
the URL of the HTTP server. This URL can contain certain keywords that
will be replaced before the URL is called.
Below this template, you can specify the HTTP request method by
selecting the GET or the POST radio button.
To configure logging related to the Colour SMS user, click
the Logging tab in the Configuration panel.
The tab has a Logging and a Log file settings section.
Here, you can choose whether to make the program write log entries about
sent and received messages
in human readable format and/or log low level communication. Choosing the latter
option will make the program produce logfiles containing binary codes
representing the communication data.
You should check at least the Log sent and received messages
in human readable format checkbox, as logfiles can be useful in
debugging communication problems (Figure 5).
Figure 5 - Logging options
In the Log file settings section of the tab, you can
make specifications for the size and the number of available logfiles.
Log rotation saves disk space, as it ensures that older (and probably
no longer needed) logfiles will be automatically deleted from the log
directory, which is specified in the
Log directory text box. By default, the access path to the logfiles is:
C:\Program Files\Ozeki\OzekiNG - SMS Gateway\Logs
In the Maximum log file size text box in the Logfile
settings section, you can specify the maximum size of a logfile.
Once this size is reached, a new logfile will be created. Specify the number
of kilobytes for the size of a logfile by entering a positive whole number.
By default, the maximum logfile size is 8000 kB.
In the Number of rotated files text box,
specify the maximum number of rotated logfiles that are saved. Specify
this number by entering a positive whole number. By default, the number
of logfiles that are saved is 4 (see Figure 5 above).
If you are content with the default specifications, leave
the text boxes unchanged.
To modify the configuration or to view server events related to
a Colour SMS user, open the panel of the user's account. To do this, click
the name of the user in the Users and Applications panel of the
Management Console. In the panel of the user's account, click the link of
the task you wish to perform (Figure 6).
