Unified Radio Application (URA): Radio Application which complies with the reconfigurable RE framework defined

ITU-T International Telecommunication Uniton Telecommunication Standardization Sector

A reconfigurable RE is capable of running multiple radios simultaneously, changing the set of radios by loading new

Radio Application Packages (RAP) and setting their parameters. All Radio Applications (RAs) are called Unified Radio

Applications (URAs) when they exhibit a common behaviour from the reconfigurable RE's point of view in ETSI

EN 303 648 [i.2]. In order to run multiple URAs, the reconfigurable RE will include Communication Services Layer

(CSL), Radio Control Frameworks (RCFs), Radio Platforms and 4 sets of interfaces for their interconnection.

Figure 4.1 illustrates the Reconfigurable RE architecture with the 4 sets of interfaces, i.e.:

• gRPI for allowing an independent and uniform production of RAs (in ETSI EN 303 681-4 [i.14]).

Figure 4.2 illustrates UML class diagram for Radio Computer interfaces. The reconfigurable RE may be seen as a set of

multiple Radio Computers where individual URAs are engineered as software entities in ETSI EN 303 648 [i.2].

• clause 6 describes the notational tool for defining both information model classes and interface classes;

While UML is used for defining the information model and protocol related to gMURI, other modeling languages could

- These services are used by some device configuration application i.e. Administrator which is included in

the CSL, to (un)install a new URA into the Reconfigurable RE and create/delete an instance of the URA.

Installation and loading may take place both at device start-up time to set up the network connection as

well as during run-time, whenever reconfiguration of available URAs is needed. gMURI does not make

any assumption on how and when the Radio Equipment will detect the need of the reconfiguration.

- These services are used by the MPM to maintain the user policies and preferences related to the usage of

different RATs and to make a selection between them. Modelling of such preferences and selection

algorithms is not in the scope of the present document; however, the gMURI specification covers the

information exchange of RAT selection decisions between CSL and RCF. The preferences themselves

may originate either locally from applications or end user settings as well as in a distributed manner from

- These services are used by the networking stack of the Reconfigurable RE, such as the TCP/IP stack.

Therefore data flow services represent the set of (logical) link layer services, which are provided in a

The Communication Services Layer (CSL) and Radio Control Framework (RCF) are defined in ETSI EN 303 648 [i.2].
