accepted-smsc = B

get-url = "..."

As can be seen, the smsc-idis used to identify the SMS center from which the message came. Then, the denied-smsc-idvariable is used to prevent messages originally from the other SMS center from being sent through the other one. Finally ’sms-service’ groups are deﬁned with accepted-smscso that they only accept messages from certain SMS center.

If you want to use SMS push services, requesters should then set the smsc request parameter, or ’sendsms-user’ groups should be deﬁned like this:

group = sendsms-user username = operator_A password = foo forced-smsc = A

group = sendsms-user username = operator_B password = bar forced-smsc = B

Note that if your SMS centers do not set the sender phone number but rely on number transmitted, you should set faked-senderto all ’sendsms-user’ groups.

Using the HTTP interface to send SMS messages

After you have conﬁgured Kannel to allow the sendsms service, you can send SMS messages via HTTP, e.g., using a WWW browser. The URL looks something like this:

http://smsbox.host.name:13013/cgi-bin/sendsms?

username=foo&password=bar&to=0123456&text=Hello+world

Thus, technically, you make an HTTP GET request. This means that all the information is stuffed into the URL. If you want to use this often via a browser, you probably want to make an HTML form for this.

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.
