Abstract: The embodiments of the present invention provide a method for positioning using wireless signal and a positioning server. The coverage area of wireless signal is divided into multiple grids. The method comprises: acquiring speed information of UE; and determining a grid, in which the UE is located, based at least upon the speed information of the UE and speed information of the grids. Accordingly, according to the embodiments of the present invention, when the UE is positioned by using the wireless signal, the grid in which the UE is located is determined by using the speed information of the UE and the speed information of the grids, so that pattern matching may be performed more accurately and the positioning precision is improved.

Abstract: A data migration method is disclosed. The method includes: performing, by a source base station, a TCP proxy for user equipment; learning, by the source base station, that the user equipment is to be handed over to a target base station; sending, by the source base station to the target base station, context information including a sequence number of a data packet, and the sequence number of the data packet is a largest sequence number of data packets that have been acknowledged by the user equipment or a smallest sequence number of data packets that have not been acknowledged by the user equipment; and migrating, by the source base station by using the SCTP, the data packets that have not been acknowledged by the user equipment to the target base station.
