How long the message will be

 

 

valid, i.e., how long the SMS

 

 

center (the real one, not the

 

 

phone acting as one for Kannel)

 

 

will try to send the message to

 

 

the recipient. Encoded as per the

 

 

GSM 03.40 standard, section

 

 

9.2.3.12. Default is 167, meaning

24 hours.

 

 

Assuming that kannel is well

 

 

configured and we had one

true, kannel will always retry the

 

 

connection even if some related

Whether to enable the so-called

 

 

"SIM buffering behaviour" of the

 

 

GSM module. if assigned a true

 

 

value, the module will query the

 

 

message storage memory of the

 

 

modem and will process and

 

 

delete any messages found there.

 

 

this does not alter normal

 

 

behaviour, but only add the

 

 

capability of reading messages

 

 

that were stored in the memory

 

 

for some reason. The type of

 

 

memory to use can be selected

 

 

using the ’message-storage’

 

 

parameter of the modem

 

 

configuration. Polling the

 

 

memory is done at the same

 

 

interval as keepalive (if set) or 60

 

 

seconds (if not set). NOTE: This

 

 

behaviour is known to cause

 

 

minor or major hicups for a few

 

 

buggy modems. Modems known

 

 

to work with this setting are

 

 

Wavecom WM02/M1200 and the

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.
