Embodiment Construction

[0040] Such as image 3 Shown is an example of a multi-sector cell network. In the figure, cell 1 is composed of sector A and sector B. Sector A and sector B have the same cell ID and are the same cell. The signals of sector A and sector B inside the base station share a radio frequency transceiver channel, but pass through different feeders and antennas respectively. So sector A and sector B exist T RX通道时延 and T TX通道时延 The difference is mainly caused by the difference between the feeder and the antenna. Since the difference between the antenna is very small, the actual main delay difference comes from the difference in the length of the feeder.

[0041] After the network layout is completed, the feeder type and length of each sector are known. Since the propagation speed of the signal in a specific feeder is constant, the T of sector A and sector B RX通道时延 and T TX通道时 延 The difference can be known. At the same time, even if the feeder length difference cannot be known, T ...

Abstract

This invention relates to a wireless positioning technology, which particularly relates to a method for calibrating the RTT measured value in positioning technology for multi-sector area. In the case of multi-sector area, the specific sector where the UE locates in the multi-sector area is identified by the use of the information of adjacent areas. Then RTT value is calibrated based on the relay value of RF channel of the sector, after that, a method is selected according to the RTT value to position continuously.

Description

technical field [0001] The invention relates to a wireless positioning technology, in particular to a method for correcting the RTT measurement value in the multi-sector cell positioning technology. Background technique [0002] The research on wireless positioning technology began with the automatic vehicle positioning system in the 1960s, and then the technology was widely used in public transportation, taxi dispatching, and public security tracking. Later, as people's demand for location-based information services increased, wireless positioning technology received more attention from researchers. improvement. [0003] With the development of the mobile communication industry, business innovation has become the fundamental driving force for the development of networks and technologies. At the same time, the operating model of new business is changing, and a healthy value chain is the basic guarantee for the development of new business. [0004] At present, the voice se...
