Chapter 5. Setting up a SMS Gateway

Variable

Value

Description

 

 

Optional, defaults to 100

 

 

miliseconds. The sleep time after

sendline-sleep

number (miliseconds)

sending a AT command.

 

 

Optional, defaults to "AT". If

 

 

keepalive is activated in AT2

 

 

group, this is the command to be

 

 

sent. If your modem supports it,

 

 

for example, use

 

 

"AT+CBC;+CSQ", and see in

 

 

logs the reply "+CBC: 0,64"

 

 

(0=On batery, 64% full) and

 

 

"+CSQ: 14,99" (0-31, 0-7: signal

 

 

strenght and channel bit error

 

 

rate; 99 for unknown). See 3GPP

keepalive-cmd

string

27007.

 

 

Message storage memory type

 

 

to enable for "SIM buffering".

 

 

Possible values are: "SM" - SIM

 

 

card memory or "ME" - Mobile

 

 

equipment memory (may not be

 

 

suppoerted by your modem).

 

 

check your modem’s manual for

 

 

more types. By default, if the

 

 

option is not set, no message

 

 

storage command will be sent to

 

 

the modem and the modem’s

 

 

default message storage will be

message-storage

string

used (usually "SM").

 

 

Optional, defaults to false. If

 

 

enabled, kannel would send an

 

 

AT+CMMS=2 if it have more

 

 

than one message on queue and

 

 

hopefully will be quickier

enable-mms

boolean

sending the messages.

A note about delivery reports and GSM modems: while it is possible (and supported) to receive delivery reports on GSM modems, it may not work for you. if you encounter problems, check that your modem’s init string (if not the default) is set to correctly allow the modem to send delivery reports using unsolicted notification (check your modem’s manual). If the init-string is not set as si, some modems will store delivery reports to SIM memory, to get at which you will need to enable sim-buffering. finally your GSM network provider may not support delivery reports to mobile units.

Fake SMSC

Fake SMSC is a simple protocol to test out Kannel. It is not a real SMS center, and cannot be used to send or receive SMS messages from real phones. So, it is ONLY used for testing purposes.

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.
