摘要： The present disclosure is applied to the field of communications, and provides a channel assignment, acquisition method and system, the assignment method including: selecting at least one idle channel from idle channels of a multi-channel sharing system as a control channel; sending an idle signal to the control channel, the idle signal identifying that the control channel is a control channel for a customer premise equipment (CPE) to be positioned therein in a preset positioning manner; and upon receipt of a communication request from a CPE positioned to the control channel, assigning the control channel to the CPE. The present disclosure, by selecting one idle channel as a control channel, positioning a CPE to the control channel after the CPE scans the control channel, and conducting communication through the control channel, can not only achieve dynamic assignment of the channel, but also make the amount of computation of the dynamic assignment small and control complexity of the dynamic assignment lower.

摘要： A data query method is provided. A data query request for a target data model is obtained. Based on the data query request and target metadata corresponding to the target data model, a target physical table corresponding to the data query request is determined from a plurality of physical tables corresponding to the target data model. The target metadata is determined based on the plurality of physical tables. The plurality of physical tables includes a basic table and a pre-aggregated table. The basic table is configured to record basic data of one granularity, and the pre-aggregated table is configured to record data of a plurality of granularities. Target query data corresponding to the data query request is obtained based on the data query request and the target physical table.

摘要： The present disclosure is related to the communication field, and provides method, apparatus, and storage medium for wireless communication. The method includes: establishing a WIFI channel and a Bluetooth channel between communication devices; detecting a communication distance between the communication devices; and transmitting multimedia data between communication devices through the WIFI channel and transmitting a control command between communication devices through the Bluetooth channel when the communication distance between the communication devices is less than or equal to a distance threshold. With the method provided in the present disclosure, a seamless switch between Bluetooth and WIFI can be implemented, respective advantages of Bluetooth and WIFI can be combined, thereby ensuring an unobstructed communication link in a small range wireless communication system, and improving the communication quality.
