The present invention discloses a slice average subjective opinion
data sharing system, node, method and medium, including: the operator node broadcasts the slice
network data and / or the service average subjective opinion data to other
blockchain nodes; the
application service provider node broadcasts the service average subjective opinion data to other
blockchain nodes, and / or, after receiving the new block, the operator node and the
application service provider node verify whether the block and each
record format in the block are correct and complete, if the
verification is passed, the new block is added to the locally stored
blockchain and forwarded, otherwise the new block is discarded; the query
system is used for the relevant parties to access the query service
network data and its corresponding average subjective opinion data, as well as other statistical information based on this. The present invention can be used to more widely share the
service experience average subjective opinion data with the operation, management and maintenance and QoS flow data in the slice network.
