Embodiment 1

[0084] In this embodiment, taking the network side device as a base station as an example, the implementation process of Logged MDT (logged minimization drive test) when the terminal is in an idle state is described. Specifically, the data transmission method in this embodiment includes the following steps:

[0085] Step 1: When the terminal accesses the network due to reasons such as attachment, location update, or service request, the terminal provides its own wireless capability information to the base station, including whether the terminal supports Logged MDT. Further, the wireless capability information may also include whether the terminal supports logging. Record the data sending and receiving process in the idle state, etc.;

[0086]Step 2: The base station judges whether to configure Logged MDT for the terminal according to wireless capability information such as the terminal's subscription information, whether it supports Logged MDT, and whether it supports recording...

Embodiment 2

[0092] In this embodiment, taking the network side device as a base station as an example, the implementation process of Logged MDT when the terminal is in an idle state and the transmission of small data packets is abnormal is described. Specifically, the data transmission method of this embodiment includes the following steps:

[0093] Step 1: When the terminal is idle, send and receive small data packets, and the data sending and receiving fails. The possible reasons include random access failure, data packet transmission failure, etc. The details can be determined by whether the maximum number of retransmissions has been reached and whether the timer has timed out. Determine whether data transmission and reception failure occurs.

[0094] When data transmission and reception failure occurs, the terminal records the data transmission and reception failure information and stores it in the storage variable Idle-RLF-report (idle state-radio link failure-report). The data transm...

Embodiment 3

[0107] In this embodiment, taking the network side device as a base station as an example, the implementation process of Logged MDT when the connection establishment fails is described. Specifically, the data transmission method in this embodiment includes the following steps:

[0108] Step 1: The terminal initiates a connection establishment request, and can piggyback small data packets or other NAS (non-access stratum) signaling through the connection establishment request or connection establishment message;

[0109] Step 2: The terminal fails to establish a connection. At this time, the terminal judges the cause of the connection establishment failure. If the current connection establishment failure is due to the operation mode of carrying small data packets / other NAS signaling in the connection establishment request or connection establishment message , the connection establishment failure information will not be recorded; if the failure is caused by other reasons, the con...

Abstract

The invention provides a data transmission method, device and terminal, which belong to the field of mobile communication. The data transmission method includes: when the terminal is in an idle state or enters a connected state, the terminal records the data transmission process, and saves the recording result; when the terminal enters the connected state, the terminal sends the network side device if the recording result needs to be recorded. The reported indication information; the terminal receives the record result reporting request of the network side device, and reports the record result. The technical solution of the present invention can improve the reliability of MDT data, thereby improving the quality of wireless network optimization.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a data transmission method, device and terminal. Background technique [0002] Drive test is an important means for GSM (Global System of Mobile communication) network to optimize wireless network and evaluate network quality. Regional signal quality and network service quality, providing data support for network optimization. This solution requires a lot of manpower and material costs, resulting in a lot of carbon dioxide emissions, and there will be problems such as the inability to measure because the test vehicle cannot drive into some areas (such as residential buildings). [0003] Therefore, 3GPP (The3rd Generation Partnership Project, third generation partnership project) in E-UTRAN (evolved universal terrestrial radio access network, evolved universal terrestrial radio access network) / UTRAN (universal terrestrial radio access network, universal terrestrial r...
