The invention provides an indoor
mobile phone positioning method, which relates to the field of positioning and comprises the following steps of: S1, detecting IMEI (International Mobile Equipment Identity), IMSI (
International Mobile Subscriber Identity) and SUCI (Subscriber Identity Control Identity) information of a
mobile phone in a target area through
mobile phone code detection equipment, comparing with a pre-registration
database, and identifying an unregistered mobile phone; s2, covering the mobile phone code detection
signal to a target area through an indoor
distribution system, wherein the indoor
distribution system comprises a power divider, a coupler, a
feeder line and an antenna; s3, arranging a
signal switch at the joint of the power divider, the coupler, the
feeder line and the antenna, and connecting the
signal switch and the controller through an industrial
field bus; and S4, the controller controls the on-off state of each switch through the independent codes of the signal switches, and dynamically divides signal coverage sub-regions. Through the indoor
distribution system and the signal switch
dynamic control module, dynamic signal coverage and area division of the target area are realized, and the problem that in the prior art, a positioning method based on
base station signals cannot distinguish indoor micro areas is solved.
