document, it consists of Administrator, Mobility Policy Manager (MPM), Networking stack and Monitor.
link: connection from one location to another through a given Radio Access Technology for the purpose of transmitting
and receiving digital information
Radio Application (RA): software which enforces the generation of the transmit RF signals or the decoding of the
receive RF signals
NOTE 1: The Software is executed on a particular radio platform or an RVM as part of the radio platform.
NOTE 2: RAs might have different forms of representation. They are represented as:
source codes including Radio Library calls of Radio Library native implementation and Radio HAL
calls;
IRs including Radio Library calls of Radio Library native implementation and radio HAL calls;
Executable codes for a particular radio platform.
radio computer: part of mobile device hardware working under ROS control and on which RAs are executed
NOTE: A Radio Computer typically includes programmable processors, hardware accelerators, peripherals, etc.
RF part is considered to be part of peripherals.
Radio Control Framework (RCF): control framework which, as a part of the OS, extends OS capabilities in terms of
radio resource management

4 Introduction
A reconfigurable MD is capable of running multiple radios simultaneously and of changing the set of radios by loading
new Radio Application Package (RAP). All Radio Applications (RAs) are called Unified Radio Applications (URAs)
when they exhibit a common behaviour from the reconfigurable MD's point of view [i.2]. In order to run multiple
URAs, the reconfigurable MD will include Communication Services Layer (CSL), Radio Control Framework (RCF),
Radio Platform and 4 sets of interfaces for their interconnection.

Figure 4.1: Four sets of interfaces for Reconfigurable MD
Figure 4.1 illustrates the Reconfigurable MD architecture with the 4 sets of interfaces, i.e.:
• MURI for interfacing CSL and RCF [i.3];
• RRFI for interfacing URA and RF Transceiver [i.4];
• URAI for interfacing URA and RCF which is the scope of the present document;
• RPI for allowing an independent and uniform production of RAs [i.5].
The present document defines URAI.

Figure 4.2: UML class diagram for Radio Computer interfaces
Figure 4.2 illustrates UML class diagram for Radio Computer interfaces. The reconfigurable MD may be seen as a
Radio Computer where individual URAs are engineered as software entities [i.2].
The present document is organized as follows:
• clause 5 describes the system identification;
• clause 6 describes the notational tool for defining both information model classes and interface classes;
• clause 7 describes the information model for radio computer; and
• clause 8 describes the interface definition.
While UML is used for defining the information model and protocol related to URAI, other modelling languages could
be used as well.

Figure 5.1: Interconnection between RCF and URA using URAI for Reconfigurable MD
As shown in figure 5.1, URAI supports 3 kinds of services:
• Radio Application Management Services
These services are used by Radio Connection Manager (RCM) which is included in the RCF, to control URA functions
such as reporting of discovered Peer Equipments, creating/terminating association with Peer Equipment,
starting/stopping communication with Peer Equipment, etc.
• User Data Flow Services
These services are used by Flow Controller (FC) which is included in the RCF, to transmit user data to URA, or used by
URA to transmit received user data to FC. These services also include management of data flow, which is provided by
FC.
• Multiradio Control Services
These services are used by Multiradio Controller (MRC) which is included in RCF, to manage spectral resource usage.
The RCF and URA are defined in ETSI EN 303 095 [i.2].

Figure 5.1: Interconnection between RCF and URA using URAI for Reconfigurable MD As shown in figure 5.1, URAI supports 3 kinds of services: • Radio Application Management Services These services are used by Radio Connection Manager (RCM) which is included in the RCF, to control URA functions such as reporting of discovered Peer Equipments, creating/terminating association with Peer Equipment, starting/stopping communication with Peer Equipment, etc. • User Data Flow Services These services are used by Flow Controller (FC) which is included in the RCF, to transmit user data to URA, or used by URA to transmit received user data to FC. These services also include management of data flow, which is provided by FC. • Multiradio Control Services These services are used by Multiradio Controller (MRC) which is included in RCF, to manage spectral resource usage. The RCF and URA are defined in ETSI EN 303 095 [i.2]. 5.2 URAI System Requirement Mapping The Radio Computer components above described shall support the URAI system requirements shown in table 5.1 and described in clause 6 of ETSI EN 302 969 [1].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
association: logical communication link to a Radio Access Network or a peer equipment
NOTE 1: Typically, some control signalling is necessary to maintain the association. No user data transfer may
occur with only an association present, but a data flow may be established into an association for this
purpose.
NOTE 2: Peer equipment is any communication counterpart of a reconfigurable mobile device. It can be reached by
establishing a logical communication link (i.e. an association) between the reconfigurable mobile device
and peer equipment.
channel: designated part of the information transfer capability having specified characteristics, provided at the user
network interface
NOTE: It is the over-the-air wireless propagation channel which is used to convey an information signal from
transmitter to receiver. This definition is specified in ETSI EN 303 095 [i.2].
communication services layer: layer related to communication services supporting generic applications
NOTE: A communication services layer supports generic applications like Internet access. In the present
document, it consists of Administrator, Mobility Policy Manager (MPM), Networking stack and Monitor.
link: connection from one location to another through a given Radio Access Technology for the purpose of transmitting
and receiving digital information
Radio Application (RA): software which enforces the generation of the transmit RF signals or the decoding of the
receive RF signals
NOTE 1: The Software is executed on a particular radio platform or an RVM as part of the radio platform.
NOTE 2: RAs might have different forms of representation. They are represented as:
source codes including Radio Library calls of Radio Library native implementation and Radio HAL
calls;
IRs including Radio Library calls of Radio Library native implementation and radio HAL calls;
Executable codes for a particular radio platform.
radio computer: part of mobile device hardware working under ROS control and on which RAs are executed
NOTE: A Radio Computer typically includes programmable processors, hardware accelerators, peripherals, etc.
RF part is considered to be part of peripherals.
Radio Control Framework (RCF): control framework which, as a part of the OS, extends OS capabilities in terms of
radio resource management
NOTE: RCF is a control framework which consists of Configuration Manager (CM), Radio Connection Manager
(RCM), Flow Controller (FC) and Multiradio Controller (MRC). The Resource Manager (RM) is
typically part of OS.

4 Introduction
A reconfigurable MD is capable of running multiple radios simultaneously and of changing the set of radios by loading
new Radio Application Package (RAP). All Radio Applications (RAs) are called Unified Radio Applications (URAs)
when they exhibit a common behaviour from the reconfigurable MD's point of view [i.2]. In order to run multiple
URAs, the reconfigurable MD will include Communication Services Layer (CSL), Radio Control Framework (RCF),
Radio Platform and 4 sets of interfaces for their interconnection.

Figure 4.1 illustrates the Reconfigurable MD architecture with the 4 sets of interfaces, i.e.:
• MURI for interfacing CSL and RCF [i.3];
• RRFI for interfacing URA and RF Transceiver [i.4];
• URAI for interfacing URA and RCF which is the scope of the present document ;
• RPI for allowing an independent and uniform production of RAs [i.5].
The present document defines UARI.

Figure 4.2: UML class diagram for Radio Computer interfaces
Figure 4.2 illustrates UML class diagram for Radio Computer interfaces. The reconfigurable MD may be seen as a
Radio Computer where individual URAs are engineered as software entities [i.2].
The present document is organized as follows:
• Clause 5 describes the system identification;
• Clause 6 describes the notational tool for defining both information model classes and interface classes;
• Clause 7 describes the information model for radio computer; and
• Clause 8 describes the interface definition.
While UML is used for defining the information model and protocol related to URAI, other modelling languages could
be used as well.

Figure 5.1: Interconnection between RCF and URA using URAI for Reconfigurable MD
As shown in figure 5.1, URAI supports 3 kinds of services:
• Radio Application Management Services
These services are used by Radio Connection Manager (RCM) which is included in the RCF, to control URA functions
such as reporting of discovered Peer Equipments, creating/terminating association with Peer Equipment,
starting/stopping communication with Peer Equipment, etc.
• User Data Flow Services
These services are used by Flow Controller (FC) which is included in the RCF, to transmit user data to URA, or used by
URA to transmit received user data to FC. These services also include management of data flow, which is provided by
FC.
• Multiradio Control Services
These services are used by Multiradio Controller (MRC) which is included in RCF, to manage spectral resource usage.
The RCF and URA are defined in ETSI EN 303 095 [i.2].
