Open Mobile Alliance
The Open Mobile Alliance ( OMA ) is an association of leading service and product providers in the field of mobile communications with the aim of developing marketable, interoperable digital services and establishing them as a standard worldwide.
The OMA was formed in June 2002 from the previously self-sufficient organizations Open Mobile Architecture Initiative and WAP Forum. Since then, the individual organizations Location Interoperability Forum (LIF), SyncML initiative, MMS Interoperability Group (MMS-IOP), Wireless Village, Mobile Gaming Interoperability Forum (MGIF) and the Mobile Wireless Internet Forum (MWIF) have joined the OMA.
The organization consists of around 350 members, including the most important representatives of the entire value chain of the mobile communications sector and related industries such as Microsoft, Vodafone, Nokia and IBM. The aim is to ensure the interoperability of devices, software and content. In its own words, the OMA attaches great importance to the openness of its organization in order to achieve the greatest possible scope. The partners of the OMA include B. the World Wide Web Consortium. At the same time, she takes the view that only open standards such as the digital rights management standard OMA DRM enable fair competition for the best ideas.
The institute is based in La Jolla , California ( USA ). The current chairman of the organization is Jari Alvinen .
Some standards created by OMA or its predecessors:
- OMA DM - Device Management , mostly in MDAs and mobile phones
- OMA DRM - digital rights management , implemented in almost all multimedia cell phones (approx. 460 models)
- WAP (partly in cooperation with W3C )
- MMS (in cooperation with 3GPP )
- SyncML
- PoC "Push-to-Talk over Cellular" is a service similar to digital radio via the infrastructure of the mobile radio providers, also known as "Push-to-Talk" or PTT
- Instant Messaging and Presence Service (IMPS; formerly Wireless Village )
- Secure User Plane Location (SUPL)
- XHTML Mobile Profile
- Rich Communication Services (RCS) (Standard adopted in 2012 for the simultaneous transmission of text messages / chats (of any length), IP telephony, video telephony, file transfer to one or more participants)
Products
There are a number of products that include: B. enable remote management of end devices via the OMA-DM protocol, for example to implement FOTA . There are also first products such as B. ProSyst, which combine the function of an OMA-DM server with the possibilities of OSGi and TR-069 . OSGi can z. B. serve as a service-oriented architecture (SOA), which forms the framework on the terminal, on which an OMA-DM client itself, as well as other - possibly chargeable - (value-added) services can be dynamically installed and administered. This is particularly interesting if incremental updates of the device software should be possible or if the remote maintenance options of OMA DM are not sufficient.
