Embodiment Construction

[0017] refer to figure 1 , which illustrates the structure of an OTDOA positioning device provided by the present invention. The OTDOA positioning device is deployed in the RNC, specifically, the function of the positioning device is performed by the SMLC in the RNC. As shown in the figure, the RNC 100 includes a selection unit 101 , a judging unit 102 coupled to the selection unit 101 , a first acquiring unit 103 and a second acquiring unit 104 coupled to the judging unit. The RNC 100 also includes an interaction unit 105 and a reporting unit 106 .

[0018] refer to figure 1 , when the RNC 100 receives a positioning request from the core network, select the OTDOA positioning method, start from the selection unit 101, and end when the reporting unit 106 reports to the core network.

[0019] refer to figure 2 , which illustrates a method based on the present invention figure 1 The flow of the OTDOA positioning method of the OTDOA positioning device in the. As shown, incl...

Abstract

The invention discloses a method for OTDOA positioning, including: (a) SRNC selects the reference-area. (b) SRNC judges whether the reference-area is located in DRNC. If it is, the information of OTDOA positioning is obtained through the information exchanging process of the IUR interface; otherwise, it is obtained through reading the RNC database of the reference-area. (c) The positioning result is obtained through the interaction of SRNC and UE. (d) SRNC reports the positioning result to the core network. The invention can be applied for the mobile communication network to position UE.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an OTDOA (Observed Time Difference of Arrival) positioning method. Background technique [0002] In mobile communication technology, positioning technology refers to the technology of determining the geographic location of a certain network element (especially UE (User Terminal Equipment, ie mobile station)) in the mobile communication network by a certain method. These methods include the AGPS (Aided GPS) positioning method defined in the current 3GPP agreement, the OTDOA positioning method, and the CELLID+RTT (cell ID+round trip time) positioning method and the like. [0003] In WCDMA (Wideband Code Division Multiple Access) wireless access network, RNC (Radio Network Controller) is the control core. In the RNC, an SMLC (Mobile Station Location Control Center) is integrated. The SMLC is responsible for receiving a location request from the WCDMA core network to a certain UE, ...
