Open Mobile Alliance
The Open Mobile Alliance ( OMA) is a consortium of leading service and product providers in the field of mobile communications with the aim to develop marketable, interoperable digital services and as a standard to establish world.
The OMA was formed in June 2002 from the previously independently operating organizations Open Mobile Architecture initiative and the WAP Forum. Since then, also 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 ) of the OMA have connected.
The organization consists of approximately 350 members, including the most important representatives of the entire value chain of the mobile sector and adjacent sectors of industry such as Microsoft, Vodafone, Nokia and IBM. Thus, the interoperability of equipment, software and content offerings will be saved. The OMA defines his own words, a high value on the openness of their organization in order to achieve maximum effect circle. Among the partners of OMA includes, for example, the World Wide Web Consortium. At the same time it takes the view that only open standards such as the Digital Rights Management OMA DRM enables a fair contest for the best ideas.
Headquarters of the Institute is La Jolla in California (USA). The current chairman of the organization is Jari Alvinen.
Some standards that have been created by the OMA, or their precursors:
- OMA DM - Device Management, mostly in MDAs and mobile phones
- OMA DRM - digital rights management, implemented in almost all multimedia phones ( 460 models )
- WAP ( partly in cooperation with W3C)
- MMS ( in collaboration with 3GPP)
- Device Management
- Instant Messaging and Presence Service ( IMPS; formerly Wireless Village )
- XHTML Mobile Profile
- Joyn ( In 2012, the same standard approved for transfer times of ( arbitrarily long ) text messages / chats, IP telephony, video telephony, file transfer to one or more participants)
There are a number of products, for example enabling remote management of devices using the OMA DM protocol, for example, to realize FOTA. Furthermore, it is also the first products, such as ProSyst that combine the function of an OMA-DM server to the capabilities of OSGi and TR -069. OSGi can in this case, for example, as service-oriented architecture (SOA ) are used, which forms the framework on the device on which an OMA DM client itself, and others - are ( value-added) services dynamically installed and administered - possibly paid can. This is particularly interesting when incremental updates to the device software to be possible, or if the remote maintenance of OMA DM is not sufficient.
