application example 1

[0106] This application example is used to illustrate the minimum drive test method in which the network side directly modifies the MDT configuration information to directly restrict the terminal to actively trigger the acquisition of location information.

[0107] like figure 2 As shown, the method may include the following processing steps:

[0108] Step S101: The network element management system (network Element Management System, referred to as EMS) triggers the minimum drive test, and sends the first message (such as TraceSession Activation message) carrying the minimum drive test configuration information to the HSS network element; wherein, the configuration information Include measurement requirements that trigger the acquisition of location information;

[0109] Step S102: After the location register (HSS) retrieves that the UE enters the attached state, it sends a second message carrying the minimum drive test configuration information to the network element of th...

application example 2

[0126] This application example is used to illustrate a method for a terminal to actively identify and optimize trigger acquisition of location information without the help of the network side.

[0127] like image 3 As shown, the method may include the following processing steps:

[0128] Step S201: The EMS triggers the minimization of the drive test, and sends the MDT configuration information to the access network element (such as eNB or RNC) through the southbound interface; wherein, the configuration information includes the measurement requirements for triggering the acquisition of location information;

[0129] Step S202: The network element of the access network selects a suitable terminal, and sends MDT configuration information to the selected terminal, wherein the MDT configuration information includes a measurement requirement to trigger acquisition of location information. This application example is based on management-based MDT, so the access network element eN...

application example 3

[0138] This application example is used to illustrate how the terminal actively obtains location information optimally in the case of immediately minimizing the drive test.

[0139] like image 3 As shown, the method may include the following processing steps:

[0140] Step S301: The EMS triggers the minimization of the drive test, and sends the MDT configuration information to the access network element (such as eNB or RNC) through the southbound interface; wherein, the configuration information includes the measurement requirements for triggering the acquisition of location information;

[0141] Step S302: The network element of the access network selects a suitable terminal, and sends an MDT configuration to the selected terminal, wherein the MDT configuration information includes a measurement requirement to trigger acquisition of location information. This application example is a management-based MDT. The access network element eNB or RNC can select one or more suitable...

Abstract

The invention discloses a minimized drive test method and device. The method includes the step that in the minimized drive test process, a node conducts optimization and limitation on the times for conducting triggering to obtain the location information according to local configuration after receiving MDT configuration information which contains the measurement requirement for triggering to obtain location information, wherein the node comprises a terminal or a network element of a switching network. The device is the terminal or the network element of the switching network and comprises a receiving module and an optimizing and limiting module, wherein the receiving module is used for receiving the MDT configuration information which contains the measurement requirement for conducting triggering to obtain the location information, and the optimizing and limiting module is used for conducting optimization and limitation on the times for triggering to obtain the location information according to the local configuration. Through the minimized drive test method and device, the times for initiatively conducting triggering to obtain the location information through the terminal are reduced, the energy consumption problem of the minimized drive test terminal is solved on the premise of obtaining the accurate location information, and therefore the aim of improving the network function is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for minimizing drive testing. Background technique [0002] In order to reduce the cost and complexity of manual drive testing by operators using dedicated equipment, the Third Generation Partnership Projects (Third Generation Partnership Projects, referred to as 3GPP) includes base stations (Node B, Node B) and radio network controllers (Radio The Universal Terrestrial Radio Access Network (UTRAN for short) of the Network Controller (RNC for short) and the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network) including an evolved base station (eNB, evolved Node B) Version 10 (Release-10) of the Access Network (abbreviated as E-UTRAN) system begins to introduce a minimization of drive test (Minimization of Drive Test, referred to as MDT) function. The core network (Core Network, referred to as CN) corresponding to UT...
