Problems solved by technology

[0019] Embodiments of the present invention provide a method, system, and device for minimizing drive testing, which are used to solve the problem of failure to report MDT measurement result data when the data volume of the MDT measurement result data reported by the UE exceeds the data volume that can be accommodated by the PDCP module.

Embodiment 1

[0115] Figure 6B In the MDT measurement result report message, the UE indicates whether there are log results to be sent later.

[0116] Figure 6C In each log result reporting signaling, the log result content will be carried. While reporting the log result, the signaling can carry 1 bit indication information, which is used to inform the network whether there are log results to be reported later, that is: this Whether the data packet reported for the first time is the last data packet of the log result. Since the log records are sequentially obtained by the UE during continuous measurement, the UE can store the log records in the order in which they were measured. Once the data volume exceeds the limit when filling the data packet sending the log measurement results to the network, then Do not continue to fill, but indicate "there is still log result data that has not been filled, and will wait to be reported" at the corresponding position of the data packet format. The ...

Embodiment 2

[0118] The UE receives a network acquisition command, fills all stored log results into multiple data packets in sequence, and sends them.

[0119] After the network sends the signaling to the UE to report the log results, if the UE cannot complete sending all the log results in one data packet due to reasons such as PDCP size limitation, it will send them in batches. A notification signaling issued by the network does not need to report only one log result signaling, but the log results can be filled in multiple data packets and sent to the network in multiple RRC signaling, such as Figure 6D shown.

[0120] Since the UE generally stores the measured logs in order, it is hoped that the reporting order will not be confused. A "serial number" can be introduced into each reporting signaling, so that the network side can analyze and arrange all the log results according to the sending order of the UE after receiving multiple log result reporting signaling from the UE.

Embodiment 3

[0122] When reporting log available, the UE may notify the network in advance of the number of data packets to be reported subsequently, so that the network can reserve sufficient resources.

[0123] Reporting the log available indication may be in the process of connection establishment / connection re-establishment / cell update / handover completion. At this time, if the log result has not been reported, or only a few of the multiple data packets are reported, the UE can indicate the log to the network. Available also indicates that there are still several log result packets waiting to be reported.

[0124] For example: you can add an integer format RestPackages at the level indicated by log available:

[0125] 【Omitted part】

[0126] logAvailable ENUMERATED{true} OPTIONAL,

[0127] restPackages INTEGER(1..8) OPTIONAL,

[0128] 【Omitted part】

[0129] A 3bit restPackages format is added after log available, which can indicate the existence of up to 8 log reporting messages. ...

Abstract

The embodiment of the invention discloses a minimizing drive test (MDT) method, system and equipment and relates to the technical field of wireless communication. By the invention, the problem of submitting failure of MDT measured data because the data quantity of the MDT measured data submitted by the terminal is larger than the containable data quantity of a packet data convergence protocol (PDCP) module can be solved. In the method, a terminal receives information about MDT measured result submitted from a base station; and when the total data quantity of stored data of the MDT measured result to be submitted is larger than the containable data quantity of the PDCP module, the terminal submits the data of the MDT measured result once or many times, wherein the total data quantity of the data of the MDT measured result submitted each time is not larger than the containable data quantity of the PDCP module. By the method, the problem of submitting failure of the MDT measured data because the data quantity of the MDT measured data submitted by user equipment (UE) is larger than the containable data quantity of the PDCP module is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and equipment for minimizing drive testing. Background technique [0002] In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, manual participation in network planning and operation and maintenance will be reduced, and the network will automatically optimize parameters according to statistics to reduce network construction and operation costs. In order to reduce network operation and maintenance costs, it is hoped that a network configuration terminal (UE) reporting method can be adopted to reduce manual drive test work. On the other hand, it is also desirable to obtain wireless measurement information in areas that cannot be reached by ordinary drive tests. [0003] At present, in the long-term evolution (LTE) system, the tenth release (R10) has established a project to determine that the...
