The unit can be either located at the mobile device or in the network. The decision relies on

40、 the eco-system that comprises multiple entities, as such as a context information acquisition entity, context management entity, configuration management entity, flexible modulation entity and others. The radio interface engine enables the efficient acquisition and management of context information

41、 and suitable equipment configuration in a heterogeneous radio environment. 4.1 General description and reference to past work The present document will address the efficient acquisition and management of context information and suitable equipment configuration in a heterogeneous radio environment.

42、In particular, an eco-system within the equipment will be defined in order to achieve this objective. Such an eco-system may comprise entities such as: Context Information Acquisition Entity. Context Management Entity. Configuration Management Entity. Flexible Modulation Entity. And others. In i.1 a

43、 set of four use cases is described together with actors and information flows for a proposed SDR Reference Architecture for MDs. In i.2 several use cases are classified with potential requirements for future applications. In i.3 and i.8, radio link reliability key performance indicators are describ

44、ed as radio interface engine decision unit for flexible RAT management as well as flexible modulation entity. ETSI ETSI TR 103 587 V1.1.1 (2018-02) 84.2 Capabilities of a Radio Interface Engine The purpose of the radio interface engine is to provide a defined method to interchange relevant context i

45、nformation to a decision unit. The Radio Interface Engine (RIE) provides a standard interface access to model based data that could represent historical data or relies on typical alternatively characterized scenarios. The predictive decision making relies on context information which serves as input

46、 to the RIE. The reliability of the data is improved by the RIE through iterative processing including a combination of multiple sources and KPI based decision making. Figure 1 shows as an example to illustrate how an iterative process in a dynamic scenario using prior knowledge helps to improve var

47、ious performance indicators. Assuming a UE moves from network A to network B, the performance of the vertical handover depends on an accurate location estimate. The location estimate itself relies on the chosen waveform, which consequently also defines the throughput in the given scenario. The overa

48、ll throughput benefits from the current location estimate more than it loses by using a dedicated location waveform. The knowledge that the UE will remain in network A relieves the need on a precise location estimate and therefore a signal waveform can be chosen that is better for the communication

49、throughput of a single link. Figure 1: Example of an iterative procedure to improve various KPIs depending on the context information NOTE: A decision unit can be internal and/or external to the RIE. The overall decision process comprises the internal and external decision units. 5 Key Scenarios 5.1 Overview In the following key scenarios, identified in clauses 5.2 to 5.6, that will use the RIE are described. For each scenario, the following structure is used: 1) general scenario description; 2) usage example; and 3) role and usefulne
