Chapter 3. Using the gateway

Core configuration

Configuration for Kannel MUST always include a group for general bearerbox configuration. This group is named as ’core’ in configuration file, and should be the first group in the configuration file.

As its simplest form, ’core’ group looks like this:

group = core

admin-port = 13000

admin-password = f00bar

Naturally this is not sufficient for any real use, as you want to use Kannel as an SMS gateway, or WAP gateway, or both. Thus, one or more of the optional configuration variables are used. In following list (as in any other similar lists), all mandatory variables are marked with (m), while conditionally mandatory (variables which must be set in certain cases) are marked with (c).

Table 3-1. Core Group Variables

 

 

Variable

Value

Description

group (m)

core

This is a mandatory variable

 

 

The port number in which the

 

 

bearerbox listens to HTTP

 

 

administration commands. It is

 

 

NOT the same as the HTTP port

 

 

of the local www server, just

 

 

invent any port, but it must be

 

 

over 1023 unless you are running

 

 

Kannel as a root process (not

admin-port (m)

port-number

recommended)

 

 

If set to true a SSL-enabled

 

 

administration HTTP server will

 

 

be used instead of the default

 

 

unsecure plain HTTP server. To

 

 

access the administration pacges

 

 

you will have to use a HTTP

 

 

client that is capable of talking to

 

 

such a server. Use the "https://"

 

 

scheme to access the secured

admin-port-ssl (o)

bool

HTTP server. Defaults to "no".

 

 

Password for HTTP

 

 

administration commands (see

admin-password (m)

string

below)

 

 

Password to request Kannel

 

 

status. If not set, no password is

 

 

required, and if set, either this or

status-password

string

admin-password can be used

Nokia WAP and SMS gateway manual Core configuration, Variable Value Description

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.
