Chapter 5. Setting up a SMS Gateway

In addition to that you must have a dlr-dbgroup defined that specifies the table field names that are used to the DLR attributes and a sdb-connectiongroup that defines the LibSDB ressource itself.

Here is the example configuration from doc/examples/dlr-sdb.confusing a MySQL ressource:

group = sdb-connection id = mydlr

url = "mysql:host=localhost:db=dlr:uid=foo:pwd=bar"

group = dlr-db id = mydlr table = dlr field-smsc = smsc field-timestamp = ts

field-destination = destination field-service = service field-url = url

field-mask = mask field-status = status field-boxc-id = boxc

Beware that you have the DB support build in your LibSDB installation when trying to use a specific DB type within the URL.

DLR database field configuration

For external database storage of DLR information in relational database management systems (RDMS) you will have tospecify which table field are used to represend the stored data. This is done via the dlr-dbgroup as follows:

Table 5-11. DLR Database Field Configuration Group Variables

 

Variable

Value

Description

group

dlr-db

This is a mandatory variable

 

 

An id to identify which external

 

 

connection should be used for

 

 

DLR storage. Any string is

 

 

acceptable, but semicolon ’;’

 

 

may cause problems, so avoid it

 

 

and any other special

id (m)

string

non-alphabet characters.

 

 

The name of the table that is

 

 

used to store the DLR

table (m)

string

information.

 

 

The table field that is used for

field-smsc (m)

string

the smsc data.

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.
