Precise point positioning (PPP) method and a PPP device are provided. The precise point positioning method includes obtaining a first satellite signal of a target satellite and a second satellite signal of a reference satellite. The first satellite signal and the second satellite signal are combined to eliminate a signal error and obtain a combined satellite signal. A smoothing process is performed on a code data of the combined satellite signal, to obtain a satellite positioning data for positioning process. The satellite positioning data includes modified code data and modified carrier-phase data.

Precise point positioning method and positioning apparatus and recording medium thereof

Disclosed are a method and a system of device-to-device tunnel establishment between small cells, applied to a wireless backhaul management device, a first small cell and a second small cell. The method comprises: matching the first small cell and the second small cell according to a first discovery response and a second discovery response; submitting a match report; replying with a match report response; conducting a D2D connection authentication procedure between the second small cell and the first small cell; wirelessly connecting the second small cell and the first small cell, conducting a connection test and submitting a connection test report; replying with a D2D tunnel establishment decision according to the connection test report; and establishing a D2D tunnel between the second small cell and the first small cell.
