Abstract: 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.

Abstract: 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.

Abstract: A computation apparatus, a resource allocation method thereof and a communication system are provided. The communication system includes at least two computation apparatuses and an integration apparatus. The computation apparatuses transmit request contents, and each of the request contents is related to data computation. The integration apparatus integrates the request contents of the computation apparatuses into a computation demand, and broadcasts the computation demand. Each of the computation apparatuses obtains a resource allocation of all of the computation apparatuses according to the computation demand. Moreover, each of the computation apparatuses performs the data computation related to the request content according to a resource allocation of itself. In this way, a low-latency service is achieved, and reliability is improved.

Abstract: A local edge cloudlet manager, an edge cloudlet system and a controlling method of the edge cloudlet system are provided. The edge cloudlet system includes a plurality of small cell APs, a plurality of local edge cloudlet managers (LECMs) and a global edge cloudlet manager (GECM). Each of the LECMs is communicated with some of the small cell APs. The GECM is communicated with the LECMs. The controlling method comprises the following steps: Each of the LECMs transfers an authentication information of a user equipment to the GECM. Each of the LECMs sets a default bearer of the user equipment. Each of the LECMs performs a tracking area update. Each of the LECMs allocates a plurality of computing units of the small cell APs which are communicated with this one of the LECMs.
