Problems solved by technology

Because the RN node is added in the LTE-A architecture, if the positioning method in LTE Release-9 is still used, when a node initiates the positioning process, the RN cannot participate in the positioning process, and the UE that accesses through the RN cannot succeed. complete the orientation process
In summary, the positioning methods in the existing LTE-A architecture-related technologies cannot successfully implement the positioning process

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The basic idea of ​​the present invention is that in the LTE-A system, the RN participates in the location process, forwards the LPP signaling message, and processes the LPPa message, wherein, in the location process related to the RN, the RN participates in the location process as an endpoint , in the UE-related location procedure, the RN participates in the location procedure as an intermediate node, thereby completing the location procedure.

[0028] image 3 It is a flowchart of a positioning method in an LTE-A system according to an embodiment of the present invention. In this embodiment and the following other embodiments, it is taken as an example that the UE is already in the connected mode before the positioning process in the emb...

Abstract

The invention discloses a positioning method in a subsequent evolution LTE-A system of a long-term evolution. The positioning method comprises the following steps: respectively adding RN nodes into a protocol stack of E-SMLC to RN and E-SMLC to UE in the position process relevant to the RN and the position process relevant to UE, expanding an LPPa protocol on the RN, leading the RN to participatein the positioning process, carrying out forwarding on LPP signaling messages and carrying out processing on the LPPa messages. The positioning method can realize the positioning process successivelyin the LTE-A system.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a positioning method in the subsequent evolution of the long-term evolution technology (LTE-A) system. Background technique [0002] Positioning technology is a method of judging the geographic location and speed of a user equipment (UE) based on measuring wireless signals. figure 1 A schematic diagram of a UE positioning structure in a Universal Mobile Telecommunications System Radio Access Network (E-UTRAN) evolved for the Long Term Evolution (LTE) system. Such as figure 1 As shown, the Enhanced Serving Mobile Location Center (E-SMLC) is used to manage and support different location services of the target UE, including: positioning of the UE and sending assistance data to the UE. E-SMLC can interact with the serving base station (eNB) through the Mobility Management Entity (MME), and obtain the positioning measurement of the UE from the eNB, including the uplink meas...
