Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It should be understood that the data so used are interchangeable under appropriate circumstances such that embodiments of the application can be practiced in sequences other than those illustrated or described herein, and the terms "first" and "second" used herein generally do not denote any order, nor do they denote any order, for example, the first object may be one or more. In the specification and claims, "and" represents at least one of connected objects, and a character "/" generally indicates that a preceding and succeeding related object is in an "or" relationship.

It is noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE)/LTE Evolution (LTE-Advanced) systems, but may also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications, such as 6 th generation (6 th generation)^thGeneration, 6G) communication system.

In order to facilitate understanding of the embodiments of the present application, the following technical points are introduced below:

the process of sending report to network side by terminal:

the terminal can perform a series of reported measurements in an idle state (idle)/inactive state (inactive) state, wherein some reports are as follows:

(1) random Access Channel (RACH) reporting;

(2) minimization of Drive Tests (MDT) records (logged) measurement information (if the network side configures the UE);

(3) connection failure report (connEstFailReport);

(4) radio Link Failure (RLF) Report (RLF-Report);

(5) a mobile history information report (mobilityHistoryReport).

When a terminal enters a connected state (connected) from an idle state, if the terminal side has reports which are not reported to a network side before, the terminal side sends a presence indicator (availability indicator) corresponding to each report to the network side (step a in fig. 1); for example, when the terminal side has a "connection failure report" and an RLF report, the terminal sends a message to the network side when entering a connected state, and the message carries an indication field indicating the availability of connection establishment failure information (connEstFailInfoAvailable) and RLF information (RLF-InfoAvailable).

After receiving the message, the network side initiates a request message for acquiring a report to the terminal according to the self requirement (step b in fig. 1), and the message can only request a part of reports of the terminal side;

for example, when the terminal indicates to the network side that it has the RLF report and the connection failure report, the network side may autonomously select whether to acquire the report or which report to acquire, such as only carrying a request for the RLF report in the message (RLF-ReportReq) or not sending the message (i.e., not requesting any report).

After receiving the request message sent by the network side, the terminal sends the corresponding report to the network (step c in fig. 1).

Second, about the availability indication:

the messages that may currently carry a report presence indication include: RRC setup complete (RRCSetupComplete)/RRC recovery complete (RRCResumeComplete)/RRC reconfiguration complete (rrcreeconfigurationcomplete)/RRC reestablishment complete (rrcreestablshmentinformplete) (type a message) and terminal information response (UEInformationResponse) (type B message).

It should be noted that the type a message is used to indicate the existence of the terminal side report for the first time, and the type B message (UEInformationResponse) is used to notify the network side whether the report is not completely sent after the first indication. For example, when the RLF report exists, the terminal may send any one of the class a messages to the network side when entering the connected state, and carry RLF-InfoAvailable in the message to inform the network side that the UE has the RLF report. When the network side initiates a request for the RLF report and the terminal fails to send all the contents of the report (for example, the sending cannot be completed at one time due to the report data volume being too large), the terminal carries RLF-InfoAvailable in the UEInformationResponse that sends the RLF report to inform the network terminal that there are still unacquired RLF reports.

At present, the indication can only be used for indicating the report of the terminal side about the primary node (MN), and there is no indication of a mechanism related to the Secondary Node (SN) side report.

Third, regarding a terminal information request (UEInformationRequest) message:

the message is used for the network side to request the terminal to acquire corresponding information, such as requesting the terminal to send measurement (idle mode measurement) in an idle mode, recording a measurement report (logged measurement report), a connection establishment failure report (connection establishment failure report), an RACH report, and the like.

Fourth, about the terminal information response (UEInformationResponse) message:

the message is used for the terminal to send the related information requested by the network side before to the network side, for example, when ra-ReportReq-r16 is set to 'tube' in the UEInformationRequest, the terminal will include ra-ReportList-r16 in the UEInformationResponse message and send to the network side.

This message can only be used to deliver MN-related reports. May be transmitted using Signaling Radio Bearers (SRBs) 1 and SRBs 2, and SRBs 2 may be used when the logged measurement information is contained within the message.

Further, optionally, the presence indication comprises at least one of:

Embodiments of the present application are described below with reference to examples one and two.

The first embodiment is as follows: and acquiring SN logged MDT measurement reports (reporting before UE recovers MR-DC).

Step 1: the UE receives logged measurement configuration (logged measurement configuration) configured for the UE by the MN (alternatively referred to as a first network node) and the SN (alternatively referred to as a second network node) respectively in an MR-DC (connected state);

step 2: the method comprises the steps that the UE enters an idle state (idle) or an inactive state (inactive), measured values are recorded in configured areas of a first Network node and a second Network node (NR is configured according to an area of a measured cell (area configuration), LTE is configured according to a target multicast/multicast Single Frequency Network area list (target MBSFN-area list) of a multicast/multicast Single Frequency Network (MBSFN) and a configuration in the area configuration, and a logged MDT report (called MN logged MDT report) measured under the configuration of the first Network node and a logged MDT report (called logged MDT report as an SN node in an MR-DC state) measured under the configuration of the second Network node are obtained respectively;

and step 3: the UE ends idle/inactive state, first recovers the connection state with a certain cell (i.e. MN is accessed, but SN connection is not established yet), and carries an indication that MN/SN Logged MDT report exists (logmeasavailablesscg) in any of the following messages:

(a)RRCSetupComplete；

(b)RRCResumeComplete；

(c)RRCReconfigurationComplete；

(d)RRCReestablishmentComplete；

(e)RRCConnectionSetupComplete；

(f)RRCConnectionResumeComplete；

(g)RRCConnectionReconfigurationComplete；

(h)RRCConnectionReestablishmentComplete。

for example, when the UE is suspended (suspend), and receives a resume message sent from the network side, the UE resumes the connection, and at this time, the RRCResumeComplete message is used. (MN is the base station of NR system).

Or, the UE receives the reconfiguration message from the network side, and if the connection is successfully recovered, sends a rrcreeconfigurationcomplete message. (MN is base station of NR system).

It will be appreciated that the above messages may be selected based on whether the MN is a gNB or eNB, and by which procedure the terminal goes back to the connected state.

And 4, step 4: the network side determines whether a report needs to be acquired according to the requirement, and if so, sends a report request message to the UE (UEInformationRequest), wherein the report request message carries a request identifier, such as logMeasReportReqSCG, and requests the UE for a logged MDT report serving as an SN node in an MR-DC state.

In step 4, the network side may be that after the UE recovers the MR-DC connection, the MN therein determines which reports are needed for the SN according to the requirement; it is also possible that the MN forwards the obtained presence indication on the SN side report to the SN over the X2/Xn interface, depending on the SN.

And 5: UE sends a logged MDT report serving as an SN node to a network side under the MR-DC state of a request through UEInformationResponse; if the logged MDT report as the SN node in the MR-DC state cannot be completely sent in the transmission, the UE may carry logmeasavailableescg again in the UEInformationResponse message to indicate that the terminal side still has a report that is not acquired.

And 6: and the network side determines whether to acquire the report according to the requirement, and repeats the step 4 and the step 5 if the requirement is met.

The second embodiment: SN logged MDT measurement report acquisition (UE reports after MR-DC recovery)

Step 1: the UE respectively receives registered measurement configuration configured for the UE by MN (or called as a first network node) and SN (or called as a second network node) under MR-DC (connected state);

step 2: the UE enters an idle/inactive state, records measurement values in configured areas of a first network node and a second network node (NR is configured according to area configuration of a measurement cell, and LTE is configured according to targetMBSFN-area List and area configuration of the measurement MBSFN), and a logged MDT report (called MN logged MDT report) measured under the configuration of the first network node and a logged MDT report (called logged MDT report as an SN node under an MR-DC state) measured under the configuration of the second network node are respectively obtained;

and step 3: UE ends idle/inactive state, first recovers the connection state with a certain cell (namely MN is accessed, but SN connection is not established at the moment), and only carries indication information related to MN in the last MR-DC state; when the UE establishes a connection with the SN, an indication (logMeasAvailable) of the SN Logged MDT report in the last MR-DC state is carried in any of the following messages:

(a)RRCSetupComplete；

(b)RRCResumeComplete；

(c)RRCReconfigurationComplete；

(d)RRCReestablishmentComplete。

The selected first message is transmitted through an uplink information for dual connectivity (ulinformation transformformr-DC) message, that is, an RRC message sent by the terminal to the SN is carried in the ulinformation transformformr-DC and sent to the MN; after receiving the message, the MN forwards the RRC message to the SN.

And 5: a network Side (SN) determines whether a report needs to be acquired according to requirements, and if so, sends a report request message to UE (UEInformationRequest), wherein the report request message carries a request identifier, such as logMeasReportReqSCG, and requests the UE for a logged MDT report which is used as an SN node in the last MR-DC state;

step 6: UE sends a logged MDT report serving as an SN node to a network side under the MR-DC state of a request through UEInformationResponse; if the logged MDT report as the SN node in the MR-DC state cannot be sent all at this time, the UE may carry logMeasAvailable again in the UEInformationResponse message to indicate that the terminal side still has a report that is not acquired.

And 7: and the network side determines whether to acquire the report according to the requirement, and repeats the step 4 and the step 5 if the report is required.
