Embodiment 1

[0128] Embodiment 1, UE actively reports its own positioning capability information.

[0129] Assuming that the UE itself supports two positioning methods: standalone GNSS and ECID, the UE will support both standalone GNSS (currently existing parameters) and ECID (3GPP positioning capability, new parameters) through the existing "UE capability reporting" process The capability of the positioning method is notified to the eNB.

[0130] Subsequently, when the UE is in the connected state, the eNB selects the UE for MDT, then the eNB selects the ECID method for the UE to perform MDT-related positioning according to the two positioning methods supported by the UE capability, and notifies the UE through the MDT configuration message .

[0131] When the UE subsequently collects MDT measurement quantities (such as RSRP / RSRQ), it uses the ECID method to perform positioning and obtain relevant geographic location information.

[0132] Furthermore, when the UE reports its own position...

Embodiment 2

[0133] Embodiment 2: The eNB obtains the positioning capability of the UE from the MME

[0134] It is assumed that the UE itself supports three positioning methods: standalone GNSS, ECID and OTDOA, and the relevant capabilities of the UE are stored in the MME.

[0135] When the UE establishes a connection with the network, the eNB obtains the UE capability from the MME, including the UE's positioning capability (specifically, it can be realized through a corresponding request message).

[0136] Subsequently, when the UE is in the connected state, the eNB selects the UE for MDT, and the eNB selects the OTDOA method for the UE to perform MDT-related positioning according to the three positioning methods supported by the UE capability, and notifies the UE through the MDT configuration message.

[0137] When the UE subsequently collects MDT measurement quantities (such as RSRP / RSRQ), it uses the OTDOA method to perform positioning and obtain relevant geographic location informatio...

Embodiment 3

[0139] Embodiment 3: The eNB obtains the positioning capability of the UE from the E-SMLC.

[0140] It is assumed that the UE itself supports three positioning methods: standalone GNSS, ECID and OTDOA, and the relevant capabilities of the UE are stored in the E-SMLC.

[0141] After the UE establishes a connection with the network, the eNB can request the E-SMLC to obtain the positioning capability of the UE, and then the E-SMLC notifies the eNB of the capability (specifically, it can be realized through a corresponding request message).

[0142] Subsequently, when the UE is in the connected state, the eNB selects the UE for MDT, and the eNB selects the OTDOA method for the UE to perform MDT-related positioning according to the three positioning methods supported by the UE capability, and notifies the UE through the MDT configuration message.

[0143] When the UE subsequently collects MDT measurement quantities (such as RSRP / RSRQ), it uses the OTDOA method to perform positioning ...

Abstract

The invention discloses a method for selecting a minimization drive test (MDT) positioning mode and equipment. By applying the technical scheme provided by the embodiment of the invention, a base station can acquire third generation partnership project (3GPP) positioning capability information of terminal equipment, selects the MDT positioning mode for the terminal equipment according to the 3GPP positioning capability information and standalone global navigation satellite system (GNSS) capability information of the terminal equipment and the positioning capability information of the base station, and informs the terminal equipment of the MDT positioning mode, so hat the problem that the base station cannot acquire the 3GPP positioning capability information of the terminal equipment and cannot select the proper DT positioning mode for the terminal equipment in the prior art can be solved. By utilizing the method, MDT measured values are acquired, and simultaneously the aim of acquiring corresponding geographical position information is fulfilled, so that the MDT of long term evolution (LTE) Re1-11 can work.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for selecting an MDT positioning mode. Background technique [0002] In LTE (Long Term Evolution, Long Term Evolution) Rel-10 (Release 10, version 10), the introduced MDT (Minimization Drive Test, Minimization Drive Test) measurement classification includes the following two types. [0003] (1) Immediate MDT (immediate minimization drive test). [0004] MDT measurement and reporting in connected state. The RRM (Radio Resource Management, radio resource management) measurement mechanism is reused, and once the reporting conditions are met, the eNB (evolved Node B, evolved base station) / RNC (Radio Network Controller, radio network controller) is immediately reported. [0005] (2) Logged MDT (log-type minimized drive test). [0006] The MDT measurement performed in the idle state shall be reported in the subsequent connected state. Once the ...
