Description

Method for releasing terminal, positioning server, terminal and network device

technical field

E-CID positioning can use the UE to directly measure the CRS/NCRS (common reference signal) cell reference signals of the serving cell and neighboring cells, and obtain information such as time of arrival and signal strength to determine the UE location.

OTDOA positioning is to use the UE to measure the downlink dedicated PRS/NPRS (Narrowband Positioning Reference Signal, Narrowband Positioning Reference Signal) of the serving cell and the neighboring cell, and obtain the arrival time difference between the UE and the neighboring cell and the serving cell to determine the position of the UE; the UE can measure at least three Only the NPRS signal of each cell can complete the positioning.
