Embodiment 1

[0059] This embodiment implements a method for processing user permission information in an LTE network, such as Figure 5 shown, including the following steps:

[0060] Step 1. The UE initiates a radio resource control (RRC, Radio Resource Control) connection establishment process in cell a under the eNB to complete the establishment of the wireless connection, wherein the UE's current serving PLMN (Serving PLMN, or RPLMN) is PLMN1;

[0061] Step 2, eNB sends initial UE message (Initial UE Message) to MME;

[0062] Step 3. The MME sends an Initial UE Context Setup Request message (Initial UE Context SetupRequest) to the eNB. The message carries the Management based MDT Allowed (Management based MDT Allowed) indication, and the indication is allowed, and also carries the UE user permission range indication Information, the information includes the PLMN list information that the UE supports MDT measurement; the eNB stores the user permission range indication information of the U...

Embodiment 2

[0080] This embodiment realizes the processing method of user permission information when switching (or redirecting) in the network, taking UTRAN as an example, such as Image 6 shown, including the following steps:

[0081] Step 1. For a UE in a normal connection state in UTRAN cell a, the serving PLMN is PLMN1, and the user permission range of the UE includes PLMN1 and PLMN2. The RNC performs a handover decision based on the UE's measurement report or other factors (such as load overload), and decides to handover the UE to UTRAN cell b, where the serving PLMN of the UE in cell b is changed to PLMN2, which is within the scope of user permission.

[0082] Step 2, the source side RNC judges that the serving PLMN of the target cell b belongs to the PLMN indicated by the user permission range indication information of the UE, then the eNB sends a relocation required (Relocation Required) message to the core network, and the source RNC in the message reaches the target PLMN. The ...

Embodiment 3

[0099]This embodiment realizes the processing method of user permission information when handover (or redirection) is performed in the network, taking the inter-RAT Handover (inter-RAT Handover) from EUTRAN to UTRAN as an example, as Figure 7 shown, including the following steps:

[0100] Step 1. For a UE in a normal connection state in LTE cell a, the serving PLMN is PLMN1, and the user permission range of the UE includes PLMN1, PLMN2 and PLMN3. The eNB performs a handover decision based on the UE's measurement report or other factors (such as load overload), and decides to handover the UE to UTRAN cell b, where the serving PLMN of the UE in cell b is changed to PLMN2, which is within the scope of user permission.

[0101] Step 2. The eNB judges that the serving PLMN of the target cell b belongs to the PLMN indicated by the UE's user permission range indication information, and then the eNB sends a Handover Required (Handover Required) message to the MME. In the message, the...

Abstract

Disclosed is a method for transmitting Minimization of Drive Test (MDT) related information and a radio access network, for solving the problem that the access network cannot select a UE to perform an MDT measurement for lack of user consent scope indication information in multiple PLMN scenarios. The method includes: in a process of a handover or relocation of a UE, when a source RAN judges that a serving PLMN for a target RAN belongs to PLMNs indicated by user consent scope indication information of the UE, the source RAN directly transmitting the user consent scope indication information of the UE to a target RAN, or transmitting the user consent scope indication information of the UE to the target RAN over the core network. The user consent scope indication information of the UE is used for indicating the PLMNs of which the UEs support the MDT measurement. The source RAN includes a judgment module and a transmission module. The above technical solution can solve the problem that the access network cannot select a UE to perform an MDT measurement for lack of user consent scope indication information in multiple PLMN scenarios.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for sending information related to Minimization of Drive Test (MDT, Minimization of Drive Test) in a mobile communication system and a wireless access network. Background technique [0002] With the development of wireless technology and the popularization of wireless communication, wireless networks of different technologies coexist with each other, and the coverage area is also increasing. For operators, the networks and devices that need to be managed are becoming more and more complex. For network operation and maintenance, operators need to spend a lot of manpower and material resources on manual drive testing, and the efficiency is very low. In order to improve this situation, the 3rd Generation Partnership Project (3GPP, Third Generation Partnership Projects) in Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network, includi...
