Problems solved by technology

[0007] The existing technology cannot perform MDT measurement of certain types of services, for example, when performing MDT QoS measurement, because the UE can support multiple parallel services under the existing technology, for example, the UE in the E-UTRAN system can provide up to 11 parallel services services, while the current existing technology can only measure all services of the UE at the same time, but cannot further measure specific types of services, which reduces the scope of application of MDT technology

Embodiment 1

[0047] figure 1 It is a flow chart of the minimization drive test method in Embodiment 1 of the present invention, such as figure 1 As shown, the minimum drive test method in this example specifically includes the following steps:

[0048] Step S102, the first network element receives the MDT measurement configuration parameter from the second network element, wherein the MDT measurement configuration parameter carries an MDT service type indication.

[0049] Wherein, the above MDT service type indication may include but not limited to at least one of the following: Quality of Service Identifier (QCI, QoS Class Identifier), Guaranteed Service Type (GBR / Non GBR), Radio Access Bearer Identifier (RAB / E-RAB) Wait.

[0050] The above-mentioned first network element may include but not limited to one of the following: a terminal or a network side device, such as a terminal such as UE; and a network side device such as MME, SGSN / MSC Server, eNB, RNC and so on.

[0051] The above-m...

Embodiment 2

[0060] figure 2 It is a flow chart of the method for minimizing the drive test in Embodiment 2 of the present invention, such as figure 2 As shown, it is MDT based on signaling, and the MDT function is in the immediate MDT working mode to minimize the drive test MDT. The minimum drive test method in this example specifically includes the following steps:

[0061] In step S202, the EMS triggers the minimization of the drive test, and sends a minimization of the drive test message such as a Trace Session Activation message to the HSS network element, wherein the minimization of the drive test message includes an MDT service type indication.

[0062] In step S204, after the HSS retrieves that the UE is online, it sends a minimum configuration message to the core network element where the UE is located.

[0063] Specifically, in the case of E-UTRAN network, the core network element is MME; in the case of UTRAN network, the core network element is SGSN or MSC server; for example...

Abstract

The invention discloses a minimized drive test method, network element and system. The method comprises the steps that a minimized drive test (MDT) measuring configuration parameter from a second network element is received by a first network element, wherein an MDT service type indication is carried in the MDT measuring configuration parameter, and MDT measuring results according with the MDT service type indication is reported to the second network element by the first network element. When the minimized drive test method, network element and system conducts MDT, relevant MDT measuring results to be acquired are indicated by carrying of the MDT service type indication, the MET measuring results can be accurately acquired and finer control over a minimized drive test is achieved.

Description

technical field [0001] The present invention relates to minimization of drive test (MDT, Minimization of Drive Test) technology, in particular to a minimization of drive test method, network element and system capable of indicating MDT service type. Background technique [0002] In order to reduce the cost and complexity of operators using special equipment for manual drive testing, the Third Generation Partnership Project (3GPP, Third Generation Partnership Project) includes base stations (Node B) and radio network controllers (RNC, Radio Network Controller) Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) and Release 10 (Release -10) introduced MDT functionality. The core network (CN, Core Network) corresponding to UTRAN includes a home subscriber server (HSS, Home Subscriber Server), a mobile switching center server (MSC Server, Mobile Switching Center Server), a general packet radio service GPRS support network element (SGSN...
