Problems solved by technology

However, if the versions of eNB and UE are different, eNB is an old version, eNB does not support multiple MDT PLMNs, eNB only saves the IP address of the TCE of the PLMN it serves, and does not save the IP address of TCE of other PLMNs, then the eNB The MDT record reported by the UE must be lost. After the UE sends the record to the eNB, the MDT record on the UE side will also be lost.
It can be seen that when an idle UE performs Logged MDT measurement, the MDT record saved by the UE may be lost due to reporting, and the eNB will lose the MDT record reported by the UE, resulting in the complete loss of the MDT record of the corresponding UE in the system.

Embodiment 1

[0065] In this embodiment, the MME sends the user consent information and the MDT PLMN list to the eNB. When X2 is handed over, the source eNB does not need to judge whether the serving PLMN used by the target eNB selected for the UE is in the MDT PLMN list. The source eNB The process of forwarding the user consent information and the MDT PLMN list to the target eNB, image 3For the flow of the method for supporting MDT continuous measurement in the first embodiment, during the handover process, the transmission of MDT related information from the source eNB to the target eNB is realized. Such as image 3 As shown, the method may include the following steps:

[0066] Step 301: The MME sends the UE's MDT PLMN list and its corresponding user consent information to the eNB of the cell where the UE is located.

[0067] In this step, the MME sends the MDT PLMN list and user consent information to the eNB of the cell where the UE is located. Specifically, the eNB of the cell wher...

Embodiment 2

[0090] In this embodiment, the eNB of the cell where the UE is located stores the user consent information and the MDT PLMN list. During the X2 handover process, the source eNB judges whether the destination service PLMN is in the user's MDT PLMN list according to the MDT PLMN list, so as to decide whether to add The user agrees that the information is sent to the target eNB. This embodiment is based on Figure 4 describe the process, Figure 4 The illustrated method may include the steps of:

[0091] Step 401: The MME sends the user consent information and the MDT PLMN list to the eNB of the cell where the UE is located.

[0092] Wherein, the manner in which the specific MME sends the user consent information and the MDT PLMN list to the eNB may adopt the manner in the foregoing embodiment 1, or may adopt the existing manner.

[0093] In step 402, the eNB receives the UE's measurement report, and according to the UE's measurement report, the UE needs to be handed over to t...

Embodiment 3

[0106] In this embodiment, the UE needs to enter the connected mode. If the UE saves the MDT measurement report, the UE reports an indication to the network indicating that the UE has saved the MDT measurement report. The eNB can send a message to the UE, and the UE reports the measurement report to the eNB the process of. This embodiment is based on Figure 5 describe the process, Figure 5 The illustrated method may include the steps of:

[0107] Step 501: UE camps on a cell under a certain PLMN in connected mode, and the eNB sends a Logged measurement configuration message to the UE. The Logged MDT measurement configuration message includes indications of TR, TRSR, and TCE, measurement conditions, and measurement range. The TR contains the PLMN identifier, which is called the MDT-PLMN identifier and is stored in the UE. The UE is also configured with an MDT list. The MDT PLMN list indicates which PLMNs are within the scope of which the UE can continue to perform MDT me...

Abstract

The invention provides a drive test minimization (MDT) achieving method. MDT relevant information is sent to a target eNB through an eNB, or the target eNB requests user agreement information of an MME, the user agreement information can be transmitted among multiple public land mobile networks (PLMNs), and the user agreement information is not lost in a transmitting process. The invention further provides an MDT reporting achieving method, new instructs are reported through user equipment (UE), or PLMN identifications configured for the MDT are reported to the eNB, and the eNB can correctly judge whether the UE reports measuring records to the eNB.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for supporting continuous measurement and reporting of MDT under multiple Public Land Mobile Networks (PLMN for short). Background technique [0002] figure 1 It is a system architecture diagram of System Architecture Evolution (SAE). in: [0003] User Equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) that provide UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet data network gateway (PGW) 105 is responsible for functions such as charging and lawful...
