External delivery report DLR storage | Nokia WAP and SMS gateway

Chapter 5. Setting up a SMS Gateway

External delivery report (DLR) storage

Delivery reports are supported by default internaly, which means all DLRs are stored in the memory of the bearerbox process. This is problematic if bearerbox crashes or you take the process down in a controlled way, but there are still DLRs open. Therefore you may use external DLR storage places, i.e. a MySQL database.

Following are the supported DLR storage types and how to use them:

Internal DLR storage

This is the default way in handling DLRs and does not require any special conﬁguration. In order to conﬁgure bearerbox to use internal DLR storage use dlr-storage = internal in the core group.

MySQL DLR storage

To store DLR information into a MySQL database you may use the dlr-storage = mysql conﬁguration directive in the core group.

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 mysql-connectiongroup that deﬁnes the connection to the MySQL server itself.

Here is the example conﬁguration from doc/examples/dlr-mysql.conf:

group = mysql-connection id = mydlr

host = localhost mysql-username = foo mysql-password = bar database = dlr

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

LibSDB DLR storage

To store DLR information into a LibSDB ressource (which is an abstraction of a real database) you may use the dlr-storage = sdb conﬁguration directive in the core group.

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.
