Rohill’s ODINI ecosystem concept: common IP backbone will interconnect a variety of voice and data communication networks of differing types, offering their users a wide range of interworking capabilities
For example, speech calls are supported through existing dispatcher interfaces, while migration requires a (simplifi ed) TETRA ISI, and extending coverage requires subscriber provisioning and call diversion capabilities.
Dispatch workstation: using the open ODINI specifi cations, any supplier can develop a new dispatcher solution or customize an existing one for operation within an ODINI network. T e simplicity of ODINI allows fast implementation without the worry to understand and support multiple supplier-specifi c interfaces.
Voice and data logging is enabled by capturing voice and data within the IP network through the ODINI protocol. T e logging server can attach to an ODINI group in order to receive speech, data and call-related events. If individual calls within the radio networks are also transferred out of the infrastructure, it is possible to also record these voice and data calls.
Distributed database server: this optional component within the ODINI ecosystem provides reference database records to support roaming and individual calls between radio users operating within diff erent networks. Although the routeing information is cached in the system gateways as well, the distributed database server is essential to quickly get a system up and running again after equipment or link failures occur.
T e telephony gateway supports a number of scenarios for tight integration of radio networks with VoIP telephony.
T rough the telephony gateway, users within the fi xed and mobile telephone domain can access dispatchers as well as subscribers within the radio networks, and even talk groups within one or more radio networks. Possible applications also include Public Safety Answering Point networks.
Open protocols T e goal of the ODINI initiative is to open up the proprietary solutions for mission-critical radio networks. End-users will rapidly benefi t from a wide choice of applications within the ODINI ecosystem and will enjoy increased competition and a wider choice of interoperable radio networks. ODINI is independent of the access network’s air
interface. T is enables simple integration with existing PMR networks. Also, end-to-end mobile IP services are supported, which makes TETRA more future-proof by delivering TETRA functionality through mobile IP networks. ODINI benefi ts from recent developments in IP
networking standards. Solutions are now available to build true no-single-point-of-failure IP backbones which can carry any type of IP traffi c, including ODINI speech and data. Finally, the decision to embrace open protocols and open
source is the key to wide participation of the industry, system integrators, academics and end-users. T is increases the opportunity for ODINI to become a true open standard with no reliance on any single, dominant company.
How you can participate in the development of ODINI D
contributor to the design and validation of ODINI protocols as a partner within the European HNPS project. Specifi cations, supporting documents and source code will be made publicly available at
www.odini.org A community forum is planned for interaction between manufacturers, system integrators, universities and users.
