Abstract

The invention provides a terminal locating method and device, wherein the terminal locating method comprises the following steps of: sending indication information to a terminal in a predetermined cell provided with one or more radio-frequency units, wherein the indication information is used for indicating the terminal to transmit a sounding reference signal in one or more time intervals in an LTE time slot; each time interval corresponds to one radio-frequency unit; and only the radio-frequency units corresponding to the time intervals in the one or more radio-frequency units are set to receive the sounding reference signal transmitted by the terminal in one time interval; obtaining the target time interval in the one or more time intervals when the sounding reference signal transmitted by the terminal is received; and searching the target radio-frequency unit corresponding to the target time interval in the one or more radio-frequency units, and judging that the current position of the terminal is in the signal coverage range of the target radio-frequency unit. By means of the invention, the problem that the locating precision is low due to the fact that the terminal is located in a QCELL cell merging state in the related technology can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a terminal positioning method and device. Background technique [0002] In the second generation (2G) and third generation (3G) communication systems, the indoor distribution system is usually used for indoor coverage. The entire indoor building is a cell, and the positioning of 2G / 3G is based on the cell. Under this premise It is impossible to locate indoor users at the meter level. [0003] The multi-mode integrated cell (Quad-Band CELL, referred to as QCELL) system is an innovative active indoor distribution solution, including a milliwatt power remote radio unit (pico Remote Radio Unit, referred to as pico RRU), a convergence unit pBridge and indoor baseband processing unit (Building Baseband Unit, referred to as BBU) three kinds of network elements, network architecture diagram see figure 1 ,Such as figure 1 As shown, the QCELL system includes three network elements: an...
