Chapter 5. Setting up a SMS Gateway

Variable

Value

Description

 

 

Defines what kind of action

 

 

should be taken if the the ack of

 

 

a message expires. The options

 

 

for this value are: 0x00 -

 

 

disconnect/reconnect, (default)

 

 

0x01 - as is now, requeue, but

 

 

this could potentially result in the

 

 

msg arriving twice 0x02 - just

 

 

carry on waiting (given that the

 

 

wait-ack should never expire this

wait-ack-expire

number

is the mst accurate)

 

 

This SMSC can support two

 

 

types of flow control. The first

 

 

type of flow control is a

 

 

stop-and-wait protocol, when

 

 

this parameter equals to ’1’.

 

 

During the handling of

 

 

commands, no other commands

 

 

shall be sent before the a

 

 

response is received. Any

 

 

command that is sent before the

 

 

reception of the response will be

 

 

discarded. The second type of

 

 

flow control is windowing,

 

 

when this parameter is unset or

 

 

equals ’0’. In this case a

 

 

maximum of n commands can be

 

 

sent before a response is

flow-control

number

received.

 

 

When using flow-control=0,

 

 

emi works in windowed flow

 

 

control mode. This variable

 

 

defines the size of the window

 

 

used to send messages. (optional,

window

number (messages)

defaults to the maximum - 100)

 

 

If SMSC requires that kannel

 

 

limits the number of messages

 

 

per second, use this variable.

throughput

number (messages/sec)

(optional)

 

 

Assuming that kannel is well

 

 

configured and we had one

 

 

sucessful connection, if retry is

 

 

true, kannel will always retry the

 

 

connection even if some related

retry

boolean

error ocur.

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.
