Abstract: The present disclosure discloses a communication method and device in the field of communication technology. The method includes: transmitting at least one level information of the UE to a base station, the level information being used for indicating a transmission rate of the UE for communication, when a first service is triggered, querying first level information corresponding to the first service in a corresponding relationship between the service and the level information of the UE, and if the at least one level information comprises the first level information, transmitting a first service request to the base station at a transmission rate indicated by the first level information, the first service request being used for requesting the base station to communicate with the UE for the first service according to the transmission rate indicated by the first level information.

Abstract: The disclosure relates to technology for mining data in a database by recursively mining a conditional frequent pattern tree (FP-tree) for frequent items of each conditional pattern base for each node in an FP-tree to obtain frequent patterns. For each branch in the FP-tree, a single-item node table (NT) is generated for which a selected one of the frequent items appears in the node of the branch. The single-item NT including a list of all of the frequent items appearing in the FP-tree and a corresponding frequent item count. For each single-item NT of each branch generated for the selected one of the frequent items, the frequent item count of each frequent item is summed in the single-item NT formed for each branch to generate a combined single-item NT, and association rules based on the frequent patterns are generated for each of the frequent items and the combined single-item NT.
