Embodiment 1
[0044] Embodiment 1 of the present invention minimizes the drive test method, such as figure 2 As shown in , an access device that obtains a minimum drive test (MDT) measurement result performs the following steps:
[0045] Step 201: a list obtaining step, obtaining a minimum drive test (MDT) public land mobile network (PLMN) list;
[0046] In the step of obtaining the list, the access device that obtains the MDT measurement result may obtain the MDT PLMN list from a user equipment (UE) or a core network.
[0047] If the MDT PLMN list is obtained from the UE, the following procedure may be used:
[0048] The access device that triggers the MDT measurement sends MDT configuration information to the UE, and the MDT configuration information includes an MDT PLMN list and a tracking reference PLMN attribute value;
[0049] The UE sends the MDT measurement result, the MDT PLMN list, and the tracking reference PLMN attribute value to the access device that obtains the MDT measure...
Embodiment 2
[0113] Embodiment 2 of the present invention minimizes the drive test method, as Figure 4 As shown in , an access device that obtains a minimum drive test (MDT) measurement result performs the following steps:
[0114] Step 401: a list obtaining step, obtaining a minimum drive test (MDT) public land mobile network (PLMN) list from the core network;
[0115] Step 402: Judging whether the MDT measurement result is allowed to be obtained, and if it is judged to be allowed, obtain the MDT measurement result;
[0116] Among them, the conditions for allowing access are:
[0117] Both the primary PLMN and the PLMN currently registered by the UE are included in the MDT PLMN list;
[0118] There is an intersection among the PLMN sets of all trace collection entities (TCEs) connected to the access device that obtains the MDT measurement result, the PLMN currently registered by the UE, and the MDT PLMN list.
[0119] Step 403: a legality judging step, using the MDT PLMN list to detec...

Abstract
The invention relates to a minimization drive test method, access equipment and system which all support multiple PLMNs. The access equipment for acquiring a MDT (Minimization Drive Test) measurement result performs the following steps: acquiring a list, to be specific, acquiring a MDT PLMN list; judging legality, to be specific, utilizing the MDT PLMN list to detect whether the PLMN of the acquired MDT measurement result is legal or not; reporting the measurement result, to be specific, when judgment shows that the PLMN is legal, reporting the MDT measurement result. The method, the access equipment and the access system can support a logged MDT function and realize multiple PLMN scenes.
Description
technical field [0001] The present invention relates to the communication field, in particular to a branch minimization drive test method, access equipment and a system. 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 Projects) in the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network, including the base station Node B and Radio Network Controller (RNC) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network, including Evolved Base Station eNB) system version 10 (Release-10) began to introduce the minimum drive test ( MDT, Minimization of Drive Test) function. The core network (CN, Core Network) corresponding to UTRAN includes a host subscriber server (HSS, Home Subscriber Server), a mobile switching center ser...
