Chapter 5. Setting up a SMS Gateway

Variable

Value

Description

 

 

The number that the SMSC will

 

 

add in front of the sender number

 

 

of all messages sent from

 

 

Kannel. If Kannel is asked to

 

 

send a message, it will remove

 

 

this prefix from the sender

 

 

number so that the SMSC will

 

 

add it again. If the prefix was not

 

 

present, Kannel will log a

 

 

warning and will not send the

 

 

sender number. If

 

 

sender-prefixis not set, or is

 

 

set to "never", then Kannel will

 

 

not send the sender number to the

 

 

SMSC at all. If you want Kannel

 

 

to pass all sender numbers to the

 

 

SMSC unchanged, then just set

 

 

sender-prefix to the empty

sender-prefix

string

string "".

CMG UCP/EMI 4.0

Kannel supports two types of connections with CMG SMS centers: direct TCP/IP connections (emi_ip or emi2) and ISDN/modem (X.25 over D channel ISDN is called X.31) connection (emi). emi2 is a new implementation of the EMI protocol that supports more features and should work more reliably than the old one. It is the recommended one to use with TCP/IP connections. Sample configurations for these are:

group = smsc smsc = emi2

#smsc = emi_ip to use the old implementation host = 103.102.101.100

port = 600 smsc-username = foo smsc-password = bar keepalive = 55

our-port = 600 (optional bind in our end)

receive-port = 700 (the port in which the SMSC will contact) idle-timeout = 30

group = smsc smsc = emi

host = 100.102.100.102

phone = ...

device = /dev/tty0 smsc-username = foo smsc-password = bar

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.
