Abstract

A method for predicting a quality of service for a communication between at least two moving communication partners, wherein the prediction is based on at least one link-based quality of service map that is updated in a link-based QoS map generation process. Since classical radio maps are node-based, the classical radio maps are not appropriate for estimating an end-to-end latency for the communication link. The end-to-end latency is needed when determining whether safety critical messages are to be exchanged over this communication link.

First claim

The invention claimed is:

1. An apparatus for predicting a quality of service (QoS) for communication between at least two moving communication partners, the apparatus comprising:
a processing device configured to perform communication management partner operations,
wherein the at least two moving communication partners apply multi-radio access technology (RAT) communication technology, wherein the at least two moving communication partners are equipped with a plurality of different radio access technologies, each of the plurality of different radio access technologies being arranged for a corresponding RAT communication link of a plurality of RAT communication links,
wherein prediction of QoS for communication between the at least two moving communication partners is performed for at least two of the plurality of RAT communication links, wherein the prediction is based on at least one RAT communication link-based QoS map that is updated by a link-based QoS map generation process, the link-based QoS map generation process including link quality data gathering for ongoing communications on the plurality of RAT communication links from other communication partners, data gathering of dynamics of movement of the other communication partners, creating a path-loss map based on a scene understanding derived from an environment observation of at least one of the other communication partners, creating a technology utilization map showing current load of the respective RAT communication link at least in an area of interest, and generating a link-based QoS map as a decentralized QoS representation, wherein the link-based QoS map includes information about end-to-end latency for a data transmission over the respective RAT communication link.

2. A transportation vehicle comprising the apparatus of claim 1 .

3. A backend server comprising the apparatus of claim 1 .

4. The apparatus of claim 1 , wherein the link-based QoS map generation process is performed in at least one communication management partner of the at least two moving communication partners.

5. The apparatus of claim 1 , wherein a spatio-temporally extended link-based QoS map is created by combining the knowledge of the communication management partner with the knowledge of the link-based QoS maps of at least one other communication partner pair.

6. The apparatus of claim 5 , wherein combining the knowledge about the link-based QoS map of the communication management partner with the knowledge of the link-based QoS maps of at least one other communication partner pair is performed by transferring the link-based QoS map of the at least one other communication partner pair to the communication management partner and performing data fusion between at least one entry in the link-based QoS map of the communication management partner with the corresponding entries in the link-based QoS maps of the at least one other communication partner pair.

7. The apparatus of claim 6 , wherein for the operation of data fusion an operation of selecting an area of interest is performed in the communication management partner and wherein the data fusion operation is performed for the area of interest.

8. The apparatus of claim 1 , wherein the link-based QoS map includes an information about the packet error rate PER for a data transmission over the RAT communication link.

9. The apparatus of claim 1 , wherein an operation of deciding for the different RAT communication links of the multi-RAT technology which communication partners from the moving communication partners shall use which RAT communication link is performed in the communication management partner, wherein the communication management partner performs an operation of informing the moving communication partners about the link-by-link decision from the operation of deciding.

10. The apparatus of claim 5 , wherein for the operation of combining the knowledge about the link-based QoS map of the communication management partner with the knowledge of the link-based QoS maps of at least one other communication partner pair, an operation of mapping the predicted future perceived environment with the environments from the previous environment perception measurements of the at least one other communication partner pair is performed and a future channel representation is selected for which the mapping between the predicted future environment and the environment from the previous environment perception measurements is best.

11. The apparatus of claim 10 , wherein the operation of mapping includes an operation of determining the correlation between the predicted future perceived environment and the environment from the previous environment perception measurements of the at least one other communication partner pair and applying the correlation degree to select a future channel representation, for which the likelihood between the predicted future environment and the environment from the previous environment perception measurements is maximized.

12. A non-transitory computer readable medium including a computer program included in program code, which when run in a processing device performs communication management partner operations,
wherein the at least two moving communication partners apply multi-radio access technology (RAT) communication technology, wherein the at least two communication partners are equipped with a plurality of different radio access technologies, each of the plurality of different radio access technologies being arranged for a corresponding RAT communication link of a plurality of RAT communication links,
wherein prediction of (QoS) for communication between the at least two of the moving communication partners is performed for at least two of the plurality of RAT communication links, wherein the prediction is based on at least one RAT communication link-based QoS map that is updated by a link-based QoS map generation process, the link-based QoS map generation process including link quality data gathering for ongoing communications on the plurality of RAT communication links from other communication partners, data gathering of dynamics of movement of the other communication partners, creating a path-loss map based on a scene understanding derived from an environment observation of at least one of the other communication partners, creating a technology utilization map showing current load of the respective RAT communication link at least in an area of interest, and generating a link-based QoS map as a decentralized QoS representation, wherein the link-based QoS map includes information about end-to-end latency for a data transmission over the respective RAT communication link.

13. The non-transitory computer readable medium of claim 12 , wherein the link-based QoS map generation process is performed in at least one communication management partner of the at least two moving communication partners.
