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: connecting one location to another through a given Radio Access Technology for the purpose of transmitting and receiving digital information NOTE: Each Link is conveyed over a given Channel. 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. reconfigurable mobile device: mobile device with radio communication capabilities providing support for radio reconfiguration NOTE: Reconfigurable Mobile Devices include but are not limited to: Smartphones, Feature Phones, Tablets, and Laptops.

All Radio Applications (RAs) are called Unified Radio Applications (URAs) when they exhibit a common behavior from the reconfigurable MD's point of view in ETSI EN 303 095 [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 which is the scope of the present document; • RRFI for interfacing URA and RF Transceiver in ETSI TS 103 146-2 [i.3]; • URAI for interfacing URA and RCF in ETSI TR 102 839 [i.4]; • RPI for allowing an independent and uniform production of RAs in ETSI TR 102 839 [i.4]. The present document defines MURI. SIST EN 303 146-1 V1.2.1:2016

The reconfigurable MD may be seen as a Radio Computer where individual URAs are engineered as software entities in ETSI EN 303 095 [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 MURI, other modeling languages could be used as well. 5 System Identification 5.1 Radio Computer Structure Figure 5.1 illustrates how CSL and RCF interact with each other using MURI.

Figure 5.1: Interconnection between CSL and RCF using MURI for Reconfigurable MD As shown in figure 5.1, MURI supports 3 kinds of services: • Administrative Services 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 MD 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. MURI does not make any assumption on how and when the mobile device will detect the need of the reconfiguration. • Access Control Services 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 MURI 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 network operator or from a cognitive radio management framework. • Data Flow Services These services are used by the networking stack of the Reconfigurable MD, such as the TCP/IP stack. Therefore data flow services represent the set of (logical) link layer services, which are provided in a uniform manner regardless of which URAs are active. The Communication Services Layer (CSL) and Radio Control Framework (RCF) are defined in ETSI EN 303 095 [i.2]. 5.2 MURI System Requirement Mapping The Radio Computer components above described shall support the MURI system requirements shown in table 5.1 and described in clauses 6.1 and 6.2 of ETSI EN 302 969 [1].
