Embodiment 1

[0116] Figure 8 It is a schematic diagram of the implementation process of the indication and reporting method of the Logged MDT measurement result during the handover process. As shown in the figure, when the UE is handed over from eNB1 to eNB2, the following steps may be included:

[0117] Step 801, UE sends a log available indication notification to eNB1, and carries the number of segments;

[0118] Step 802, eNB1 notifies UE to report Log result 1;

[0119] Step 803, UE reports Log result 1 to eNB1;

[0120] Step 804, eNB1 notifies UE to report Log result 2;

[0121] Step 805, a handover occurs, and the UE is handed over from eNB1 to eNB2;

[0122] Step 806, eNB1 notifies eNB2 of the log acquisition situation;

[0123] Step 807, eNB2 notifies UE to report Log result 2;

[0124] Step 808, UE reports Log result 2 to eNB2;

[0125] Step 809, receiving is completed.

[0126] In this embodiment, when the UE sends the log available indication, it also carries the number ...

Embodiment 2

[0128] For the case that the UE reports an error in the Logged MDT measurement result, the PDCP is used as the bottom layer for description in this embodiment.

[0129] Existing RRC entities do not have a segmentation function. If the log data is segmented in RRC and sent in different RRC signaling, an acknowledgment mechanism and a retransmission function in RRC are required.

[0130] After the existing RRC entity sends the assembled data packet to the bottom layer, it will not confirm whether the packet is sent successfully. However, the PDCP entity has encryption and integrity protection functions, and can know the sending status of the data packet. Therefore, it is necessary for the PDCP to use inter-layer interaction to notify the RRC whether the segment of log data is successfully sent after learning the sending status of the RRC signaling on the control plane.

corresponding Embodiment 1

[0132] Corresponding to embodiment 1, if the network has the function of selecting the serial number to obtain, then regardless of the sending situation of the data packet N (N represents the serial number of the data packet), according to the network acquisition instruction, send the data packets behind the data packet N+1 and the like;

[0133] If the network does not have the function of selecting the sequence number for acquisition, it will only send the same acquisition instruction for all data packets without distinguishing the sequence number. At this time:

[0134] a), if RRC receives the failure report of the data packet N from the bottom layer, the data packet N is resent;

[0135] b), a timer timer can also be set in RRC, if the report of the data packet N has not been received for a long time, it is considered that the data packet N has failed to send, and when the log data acquisition signaling from the network is received next time, The data packet N is resent. ...

Abstract

The invention discloses a method and device for indicating and reporting a measurement result. The method comprises the steps: user equipment receives a network side notification, a network side indicates that the user equipment reports a non-simultaneous minimum drive test measurement result in the notification; and the user equipment reports the non-simultaneous minimum drive test measurement result carried through a radio resource control signaling, and carries a sequence number of the reported non-simultaneous minimum drive test measurement result in the radio resource control signaling in all reported non-simultaneous minimum drive test measurement results. By using the invention, data loss of the non-simultaneous minimum drive test measurement results can be avoided.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for indicating and reporting measurement results. Background technique [0002] (1) MDT (minimization drive test, minimization drive test) measurement classification introduction. [0003] Immediate MDT (immediate MDT): MDT measurement and reporting in connection state. The RRM (Radio Resource Management, radio resource management) measurement mechanism is reused, and once the reporting condition is met, the eNB / RNC (evolved Node B / Radio Network Controller, evolved base station / radio network controller) is immediately reported. [0004] Logged MDT (non-immediate MDT, which needs to be kept by the UE to record logs): The MDT measurement performed in the idle state is reported in the subsequent connected state. Once the configured trigger conditions are met, the measurement results will be acquired and stored (log), and reported to the eNB / RNC at a suitable s...
