Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] When the UE is in the idle state, if the LCS (Location Services, location service) client sends a location request to the CN, the CN sends a Paging message to establish a 3.4K link between the UE and the Node B of the active cell. / 13.6K link. After the link is established, the UE measures the pilot signal strength of all the cells in the monitoring set, and the measurement results are reported to the RNC through the Node B of the active cell.

[0034] Such as Figure 5 As shown, in the process of pilot signal strength measurement, if the pilot signal strength of some cells in the monitoring set reaches the pilot threshold, the RNC will add the cells that reach the pilot threshold to the active set of the UE. At this time, the UE is in the handover area In this case, the RNC will notify the UE to establish links with the Node Bs of all cells in the a...

Abstract

The invention in concerned with the method to process location of the user equipment, solving the issue of the existing technology that the locative precision of the UE is worse when the UE is in free mode, it is: the core network establishes a link between the UE and the host use plot by the calling information, the plots that the signal intensity of the UE and the testing collection achieves the fixed threshold establish link, the RNC uses the link to get the location of the UE. When using the invention to process location of the UE in the free state, and establishes several links between the UE and the different NodeB if the UE is in the switch area, processes the accurate location for the UE in order to improve the location precision of the UE in the free stat by the CELL ID and RTT mode.

Description

technical field [0001] The present invention relates to positioning technology, in particular to a method for positioning user equipment. Background technique [0002] In the wireless communication system, the location of the user equipment can be known through the positioning service, and related services can be carried out based on this. In WCDMA (Wideband Code Division Multiple Address, Wideband Code Division Multiple Access) system, a common positioning method is to use CELL ID (cell identification) + RTT (Round trip time, round trip time) to UE (User Equipment, user equipment ) position, the positioning method is to measure the distance between the UE and the Node B by calculating the round-trip time difference between the uplink and downlink signals in the cell where the UE is located, and obtain the longitude, latitude and sector of the Node B according to the CELL ID orientation, so as to obtain the position of the UE. [0003] figure 1 A schematic diagram of the ...
