Chapter 3. Using the gateway

Lines 1 and 6 are comment lines. Line 5 separates the two groups. The remaining lines define variables. The group type is defined by the group variable value.

The various variables that are understood in each type of configuration group are explained below.

Some variable values are marked as ’bool’. The value for variable can be like true, false, yes, no, on, off, 0 or 1. Other values are treated as ’true’ while if the variable is not present at all, it is treated as being ’false’.

Inclusion of configuration files

A configuration file may contain a special directive called include to include other file or a directory with files to the configuration processing.

This allows to segment the specific configuration groups required for several services and boxes to different files and hence to have more control in larger setups.

Here is an example that illustrates the include statement :

group = core admin-port = 13000 wapbox-port = 13002 admin-password = bar wdp-interface-name = "*"

log-file = "/var/log/bearerbox.log" log-level = 1

box-deny-ip = "*.*.*.*" box-allow-ip = "127.0.0.1"

include = "wapbox.conf"

include = "configurations"

Above is the main kannel.conf configuration file that includes the following wapbox.conf file with all required directives for the specific box, and a configurations directory which may include more files to include.

group = wapbox bearerbox-host = localhost

log-file = "/var/log/wapbox.log" log-level = 0

syslog-level = none

The above include statement may be defined at any point in the configuration file and at any inclusion depth. Hence you can cascade numerous inclusions if necessary.

At process start time inclusion of configuration files breaks if either the included file can not be opened and processed or the included file has been processed already in the stack and a recursive cycling has been detected.

WAP and SMS gateway specifications

Nokia has long been a pivotal player in the telecommunications industry, and its contributions to mobile communication technology are numerous. Among these contributions, the Nokia WAP and SMS Gateway stand out as essential elements in enabling mobile internet access and messaging services in the early days of wireless communication.

The Nokia WAP (Wireless Application Protocol) gateway was introduced to facilitate mobile access to the internet and to allow users to interact with web services through their mobile devices. Built on a client-server architecture, the WAP gateway acted as a bridge between the mobile network and the internet, translating traditional web content into a format that mobile devices could effectively render. This conversion was crucial, given the limitations of early mobile devices regarding screen size, processing power, and network bandwidth.

One of the main features of the Nokia WAP gateway was its ability to provide users with real-time access to information such as weather updates, news, and stock prices. By using a lightweight markup language called WML (Wireless Markup Language), the gateway allowed developers to create mobile-friendly websites that could be accessed via WAP-enabled devices. This marked a significant step toward the mobile internet we know today, creating a new realm of possibilities for developers and users alike.

Another critical aspect of Nokia's offering was the SMS (Short Message Service) gateway. The SMS gateway provided a robust platform for sending and receiving text messages across various mobile networks. It enabled seamless communication between devices, regardless of the underlying technology. This feature made SMS a popular choice for both personal communication and business applications, such as marketing campaigns and customer service notifications.

The Nokia SMS gateway utilized established protocols, such as SMPP (Short Message Peer-to-Peer), to ensure reliable message delivery and efficient interaction between SMS applications and mobile networks. Its characteristics included scalability, allowing service providers to handle large volumes of messages, and flexibility to integrate with existing applications and systems.

In summary, the Nokia WAP and SMS gateway played a vital role in the evolution of mobile communication. With features that enabled mobile internet access and streamlined messaging capabilities, these technologies laid the groundwork for the mobile-centric world we live in today. Their legacy continues to influence mobile application development and the broader telecommunications landscape. As the industry progresses, the innovations introduced by Nokia serve as a reminder of the foundational technologies that paved the way for modern mobile experiences.
