Problems solved by technology

Either way, when the terminal provides location information, if the location information is not used by the network side, the location information provided by the terminal in this case is invalid and occupies valuable air interface resources; for example, when actively triggering to obtain location information And provided to the network, if the network side does not use the location information, the behavior of actively triggering the acquisition of location information not only occupies valuable air interface resources, but also consumes valuable power of the terminal
However, if the terminal does not provide location information, the final measurement result of MDT has no location information to bind

Embodiment 1

[0058] This example illustrates that in the scenario of signaling MDT and immediate MDT, the terminal actively triggers the process of acquiring location information and determining whether to report it. Such as figure 2 As shown, the method includes the following steps:

[0059] Step 101: The network management system (EMS) triggers the drive test minimization, and sends a drive test minimization configuration message such as a TraceSession Activation message to the location register (HSS) network element, and the message contains the MDTQoS measurement requirement;

[0060] Step 102: After the location register (HSS) retrieves that the UE is in the attached state, it sends a minimization drive test configuration message to the core network element where the UE is located, and the message contains MDT QoS measurement requirements;

[0061] In the case of an E-UTRAN network, the core network element is an MME; in the case of a UTRAN network, the core network element is an SGSN or an...

Embodiment 2

[0078] This example illustrates the process of determining whether to report location information when the terminal has acquired location information (relying on location information saved after being triggered by other services) based on management MDT and immediate MDT, such as image 3 As shown, including the following steps:

[0079] Step 201: The network management system (EMS) triggers the drive test minimization, and sends the drive test minimization configuration message to the access network element, such as the eNB or RNC, through the southbound interface; the message contains the MDT QoS measurement requirement;

[0080] Step 202: The access network element selects a suitable UE, and starts MDT QoS measurement of the UE;

[0081] In this example, based on the managed MDT, the access network eNB or RNC selects the appropriate one or more UEs;

[0082] According to the configuration requirements, the access network in this example starts the UE's MDT QoS measurement. For exa...

Abstract

The invention discloses a method for minimizing drive testing and a terminal for realizing the method, which can avoid providing position information not used by the network side and save air interface resources. The method includes: after receiving the MDT configuration information, the terminal checks whether the MDT measurement object meets the requirements of the associated location information, and the terminal provides the network side with the location information of the terminal only when the terminal judges that the MDT measurement object meets the requirements of the associated location information. The terminal includes a receiving module, a checking module and a reporting module. The method and the terminal of the present invention prevent the terminal from providing invalid location information on the premise that the normal MDT measurement results of the network side can be associated with specific location information, thereby saving air interface resources, improving the use efficiency of MDT, and finally improving network performance.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a method for minimizing drive test in a wireless communication system and a terminal implementing the method. Background technique [0002] In order to reduce the cost and complexity of manual drive testing by operators using special equipment, the Third Generation Partnership Projects (3GPP) has implemented the Universal Terrestrial Radio Access Network (UTRAN), including the base station NodeB. And Radio Network Controller (RNC) and Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, including Evolved Base Station eNB) system version 10 (Release-10) began to introduce Minimized Drive Test (MDT, Minimization of Drive Test) function. The core network (CN, Core Network) corresponding to UTRAN includes a home subscriber server (location register (HSS), Home Subscriber Server), a mobile switching center server (MSCServer, Mobil...
