Appendix B. Using the fake SMS center

Fakesmsc is a simple testing tool to test out Kannel and its SMS services. It cannot be used to send messages to mobile terminals, it is just a simulated SMS center with no connection to real terminals.

Setting up fakesmsc

This section sums up needed steps to set up system for fakesmsc use.

Compiling fakesmsc

The fake SMS center should compile at the same time as main Kannel compiles. The outcoming binary, fakesmsc, is in test directory. The source code is quite simple and trivial, and is easily edited.

Conﬁguring Kannel

To use fakesmsc to test out Kannel, you have to add it to main conﬁguration ﬁle (see above). The simplest form for this conﬁguration group is like this:

group = smsc

smsc = fake

port = 10000

The fakesmsc conﬁguration group accepts all common ’smsc’ conﬁguration group variables, like smsc-id, preferred-smsc-idor denied-smsc-id, which can be used to test out routing systems and diverted services, before setting up real SMS center connections. If you include a fakesmsc group when bearerbox is connected to real SMS centers, you should add the connect-allow-ipvariable to prevent unauthorized use.

To set up multiple fakesmsc’es, just add new groups. Remember to put a different port number to each one.

Running Kannel with fakesmsc connections

After conﬁguring Kannel, you can start testing it. The bearerbox will listen for fakesmsc client connections to the port(s) speciﬁed in the conﬁguration ﬁle.

Starting fake SMS center

Each fakesmsc is started from command line, with all sent messages after command name. If any options are used (see below), they are put between the command and the messages. The usage is as follows:

test/fakesmsc [options] <message1> [message2 ...]

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.
