26、62 V1.1.1 (2011-04) 63 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: camping on a cell: having completed the cell selection/reselection process and having chosen a cell NOTE 1: In the framework of 3GPP, this term is
27、 defined in TS 125 304 i.2 as follows: UE has completed the cell selection/reselection process and has chosen a cell. The UE monitors system information and (in most cases) paging information“. NOTE2: In addition to the context defined in 3GPP, the term “Camping“ is here also used in the context of
28、any type of association to any other wireless system, such as WiFi, etc. context information: cross-technology context information NOTE 1: The availability and selected inherent operational parameters of heterogeneous Radio Access Technologies (RATs) is an example. NOTE 2: The term does not address
29、3GPP specific context information which is assumed not to be available for the SDR Reference Architecture inherent decision making. Mobile Network Operator (MNO): potential user for a specific use case Network management system: network Management of one or more Reconfigurable Radio Systems Reconfig
30、urable Radio System (RRS): radio system using reconfigurable radio technology system use case: use case describing the system functionality level and specifying the function or the service that the system provides for the user NOTE: A system use case will describe what the actor achieves interacting
31、 with the system. For this reason it is recommended that a system use case specification begin with a verb (e.g. create voucher, select payments, exclude payment, cancel voucher). Generally, the actor could be a human user or another system interacting with the system being defined. use case: descri
32、ption of a system from a users perspective NOTE 1: Use cases treat a system as a black box, and the interactions with the system, including system responses, are perceived as from outside the system. Use cases typically avoid technical jargon, preferring instead the language of the end user or domai
33、n expert. NOTE 2: Use cases should not be confused with the features/requirements of the system under consideration. A use case may be related to one or more features/requirements, a feature/requirement may be related to one or more use cases. NOTE 3: A brief use case consists of a few sentences sum

37、wide Interoperability for Microwave Access 4 Reconfigurable Radio Systems operating in licensed spectrums 4.1 General description and reference to past work TR 102 680 i.1 details an SDR Architecture for Mobile Device, highlighting in particular a set of 5 requirement groups: General architectural r
38、equirements. Capability requirements. Operational requirements. Interface requirements. Other requirements. Based on these requirement groups, an SDR Architecture has been defined as it is presented in detail by i.1 and briefly summarized in clause 4.2. The refined understanding of the final archite
39、cture proposal and the corresponding inherent capabilities that were developed during the creation of i.1 lead to the decision to create the present document for giving a detailed overview on related use cases and scenarios. 4.2 Example of a typical Reconfigurable Radio Systems capabilities The foll
40、owing capabilities of Reconfigurable Radio Systems have been derived in i.1 for a Mobile Device: a) Multiradio configuration capability: SDR equipment in mobile device is expected to install, load and activate a radio application while running a set of radio systems already. b) Multiradio operation
41、capability: SDR equipment in mobile device is expected to execute a number of radio systems simultaneously by taking into account temporal coexistence rules designed for their common operation. c) Multiradio resource sharing capability: SDR equipment in mobile device is expected to execute a number
42、of radio systems simultaneously by sharing computation, memory, communications and RF circuitry resources available on the radio computer platform by using appropriate resource allocation, binding and scheduling mechanisms. ETSI ETSI TR 103 062 V1.1.1 (2011-04) 8Building on these requirements, the f
43、ollowing components are introduced in i.1, also illustrated by: 1) Configuration Manager: (de)installation and (un)loading of radio applications into radio computer as well as management of and access to the radio parameters of those radio applications. 2) Radio Connection Manager: (de)activation of
44、 radio applications according to user requests and overall management of user data flows, which can also be switched from one radio application to another. 3) Flow Controller: sending and receiving of user data packets and controlling the flow. 4) Multiradio Controller: scheduling the requests on sp
45、ectrum resources issued by concurrently executing radio applications in order to detect in advance the interoperability problems between them. 5) Resource Manager: management of radio computer resources in order to share them among simultaneously active radio applications, while guaranteeing their r
46、eal-time requirements. Figure 1: Functional Architecture of SDR Equipment Furthermore, i.1 identifies four candidate interfaces for standardization: a) Multiradio Interface as the uniform interface for network protocol stacks and other user domain entities to access services of the radio computer. b
47、) Unified Radio Application Interface at the boundary between the common radio computer platform and the specific radio applications. c) Radio Programming Interface including software development-time concepts and run-time interfaces between radio software entities and radio computer platform. d) In
48、terface to the Reconfigurable RF Transceiver to support multiple radio applications, even concurrently. Among these interfaces, the Multiradio Interface has most potential for standardization. It is expected to enable an easier integration of radio platforms into handsets that benefits both chipset
49、vendors and device manufacturers; moreover, it offers significant functionality on top of SDR. Common methods of accessing the SDR services ease the definition and deployment of cognitive radio, providing capability to implement the functionality independently on both sides of the interface. ETSI ETSI TR 103 062 V1.1.1 (2011-04) 9The deployment of the Multiradio Interface is expected to proceed in phases with platform capability advancing, starting from legacy radio access technologies, gradually moving towards a full SDR: 1) Radio appli
