摘要： Embodiments of the present invention provide a positioning method based on a time difference of arrival, user equipment, and a network device. The method includes: calculating, by user equipment, a first time difference of arrival RSTD1 based on positioning signals sent by a first base station and a second base station at a same moment; calculating a second time difference of arrival RSTD2 based on known location information of the user equipment; calculating a time alignment error TAE based on the RSTD1 and the RSTD2; and performing, based on the TAE, positioning based on a time difference of arrival TDOA. According to this method, the TAE caused by the base stations is subtracted during positioning calculation. In other words, the time alignment error caused by the base stations is eliminated. Therefore, accuracy of TDOA-based positioning can be ensured.

摘要： Embodiments of the present invention provide a positioning information processing method and apparatus. The method includes: receiving, by a test terminal, a cell-specific reference signal sent by a base station, and obtaining an original cell-specific reference signal; obtaining, by the test terminal, a multipath characteristic quantity according to the received cell-specific reference signal and the original cell-specific reference signal; and sending, by the test terminal to a server, RSRP, timing information, and a multipath characteristic quantity that are corresponding to each test site, so that the server implements a positioning service. In the embodiments of the present invention, the multipath characteristic quantity is added as a characteristic quantity used for matching in a positioning method, that is, positioning matching is performed by using the RSRP, the timing information, and the multipath characteristic quantity. RFPM positioning accuracy is improved when being compared with accuracy of positioning matching performed by using the RSRP and the timing information; and particularly, when the timing information cannot be accurately obtained, positioning matching performed by using the RSRP and the multipath characteristic quantity has higher accuracy when being compared with positioning matching performed by using only the RSRP.
