In the embodiments disclosed herein, the disclosed method and product (including, but not limited to the apparatus and the device) may be realized in other ways. For example, the device embodiments described above are merely schematic. For example, the division of the units may be only a logical functional division, and may be an additional division manner in actual realization. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. In addition, the displayed or discussed mutual coupling or direct coupling or communication connection may be indirect coupling or communication connection through some interfaces, devices or units, and may be electrical, mechanical or other forms. The units described as separate components may or may not be physically separated, and the components shown as the units may or may not be physical units, that is, may be located in one place, or may be distributed on multiple network units. The present embodiments may be implemented by selecting some or all of the units according to actual needs. In addition, each functional unit in the embodiments of the present disclosure may be integrated into one processing unit, or each unit may exist physically alone, or two or more units may be integrated into one unit.
