What is OMA-DM?
OMA-DM is a protocol specified by the Open Mobile Alliance and is often used in the context of complex structured mobile solutions. It is often preferred by service providers to implement device management for mobile devices. These devices include mobile phones, tablets, and similar devices.
The protocol helps service providers in the configuration of devices for the first time. It can also be used later to enable certain features or disable them. OMA-DM is not only important for provisioning and device configuration, but it also enables deployments to upgrade firmware and software. There have been a number of instances in which service providers have used the OMA-DM for fixing bugs and adding new features to existing software.
Lastly, it is used in the context of fault management. Its features include reporting errors from devices, responding to queries related to device status, etc. OMA-DM was designed with mobile devices in mind. Consequently, its unique benefits include its ability to work alongside small footprint devices where storage space and memory may be constrained. It also handles low bandwidth situations well and offers watertight security in the form of authentications and challenges. In spite of many similar standards and protocols, it is frequently by service providers to remotely set parameters and troubleshoot terminals as and when necessary.
