Embodiment 1

[0114] This embodiment is applied to the LTE system, and the LCS positioning is realized through the LPP protocol, such as Figure 5A As shown, the details are as follows.

[0115] Step 1: After the coordinator receives the MDT command, if it finds that the MDT task requires accurate terminal location information, it sends an LCS request to the E-SMLC, which carries identification information indicating that the positioning task is used for MDT, and the coordinator can be UE, eNB or MME;

[0116] Step 2: The E-SMLC receives the LCS request, and performs some LPP message interaction with the UE according to the situation (such as obtaining the positioning capability of the UE through LPP message interaction, and delivering the required assistance data); and / or,

[0117] Perform some LPPa message interaction with the base station (such as obtaining auxiliary data required for positioning, etc.);

[0118] Step 3: The E-SMLC selects the LPP protocol for positioning according to ...

Embodiment 2

[0125] This embodiment corresponds to Embodiment 1, which is a solution to stop LCS, such as Figure 5B As shown, the details are as follows

[0126] Step 1: The coordinator (UE, eNB or MME) finds that the MDT task is stopped or completed, and then sends a message to the E-SMLC to stop the corresponding LCS;

[0127] Step 2: The E-SMLC sends an LPP suspend message to the UE to instruct the UE to stop the corresponding LCS positioning measurement of the UE.

[0128] In addition, it can also be as follows, such as Figure 5C Shown:

[0129] Step 1: The UE finds that the MDT task is stopped or completed, then the UE stops the corresponding LCS positioning measurement;

[0130] Step 2: The UE sends an LPP suspension message to the E-SMLC to instruct the E-SMLC to stop the corresponding LCS.

Embodiment 3

[0132] This embodiment is applied to the LTE system, and the LCS positioning is realized through the LPPa protocol, such as Figure 5D As shown, the details are as follows.

[0133] Step 1: After the coordinator receives the MDT command, if it finds that the MDT task requires accurate terminal location information, it sends an LCS request to the E-SMLC, which carries identification information indicating that the positioning task is used for MDT, and the coordinator can be UE, eNB or MME;

[0134] After receiving the LCS request, the E-SMLC can perform some LPP message interaction with the UE according to the situation (such as obtaining the positioning capability of the UE and delivering the required assistance data through LPP message interaction); and / or,

[0135] Perform some LPPa message interaction with the base station (such as obtaining auxiliary data required for positioning, etc.);

[0136] Step 2: E-SMLC selects the LPPa protocol to achieve positioning according t...

Abstract

The embodiment of the invention discloses a method, system and equipment for locating measurement and location information obtainment, relating to the technical field of wireless communication, which is used for solving the problem of quite single locating measurement triggering mode of a locating service LCS (laser communication system). The invention is characterized in that a coordination entity configures an MDT (mobile data terminal) measuring result to a locating measuring entity as the information of LCS locating measurement triggering conditions after receiving a minimum channel measurement MDT command; and the locating measuring entity receives the configuration information and carries out LCS locating measurement after obtaining the MDT measuring result. Thus, the invention provides an LCS locating measurement triggering scheme different from the prior art, and the problem of quite single LCS locating measurement triggering mode in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a positioning measurement and position information acquisition method, system and equipment. Background technique [0002] In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, manual participation in network planning and operation and maintenance will be reduced, and the network will automatically optimize parameters according to statistics to reduce network construction and operation costs. In order to reduce network operation and maintenance costs, it is hoped that a network configuration terminal (UE) report method can be adopted to reduce manual drive test work, that is, a minimized drive test (MDT) solution. On the other hand, it is also hoped that MDT can obtain wireless measurement information in areas that cannot be reached by ordinary drive tests. [0003] MDT is applied to Long Term Evolution (LT...
