Abstract: This application describes methods and system for positioning pico remote radio units. Drive test information on a terminal side and drive test information on a network management system side are recorded when a drive test is performed, and pico remote radio unit position information and a pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to facilitate positioning of a pico remote radio unit, and to ensure efficient system operation and maintenance.

Abstract: The present invention belongs to a bonding technical field of biochips or micromechanical electrical devices, more specifically, to a novel method for bonding two solid planes containing silicon, oxygen, metal or other elements at a moderate temperature via surface assembling of active functional groups. The method includes the steps of: (1) cleaning and hydroxylating solid planes of silicon plate, quartz or glass; (2) aminating a hydroxylated surfaces of the substrate; (3) forming a mono-layer or multi-layer assembled film with compound monomers having an active bi-functional or multi-functional group on an aminated substrate surface; and (4) contacting two solid planes with a assembled film having the same or different active functional groups on its surface tightly, and forming covalent bonds at an appropriate temperature, pressure and a vacuum degree.
