Description

一种无线通信方法及装置、终端设备、网络设备A wireless communication method and device, terminal equipment, and network equipment

技术领域technical field

本申请实施例涉及移动通信技术领域，具体涉及一种无线通信方法及装置、终端设备、网络设备。The embodiments of the present application relate to the field of mobile communication technologies, and in particular to a wireless communication method and device, terminal equipment, and network equipment.

背景技术Background technique

基于新无线(New Radio，NR)的V2X(即NR V2X)在基于LTE的V2X(即LTE V2X)的基础上进一步讨论了终端中继通信技术，核心思想就是当终端设备无法通过空口与网络设备直接通信时，所述终端设备通过满足条件的中继终端设备与网络设备间接完成通信，扩大了网络通信范围，提高了用户体验，但另一方面，中继终端的参与使得终端的切换控制变得复杂，现有的切换优化策略并没有考虑中继场景对切换的潜在影响。New Radio (NR)-based V2X (i.e. NR V2X) further discusses terminal relay communication technology on the basis of LTE-based V2X (i.e. LTE V2X). In direct communication, the terminal device indirectly completes communication with the network device through the relay terminal device that meets the conditions, which expands the network communication range and improves user experience, but on the other hand, the participation of the relay terminal makes the switching control of the terminal change. However, the existing handover optimization strategies do not consider the potential impact of relay scenarios on handover.

For example, the first duration and the long 1 record time are very long, indicating that the connection failed Has little to do with switching (connection failures occur long after switching), and may not require optimizing switching parameters.

网络设备能够基于数据项7至数据项9判断连接失败的原因，比如，失败时目标relay终端设备的测量结果较差，说明可能是网络设备切换过早了。The network device can determine the cause of the connection failure based on data items 7 to 9. For example, the measurement result of the target relay terminal device is poor when the failure occurs, indicating that the network device may switch too early.

对于数据项10，第一指示信息指示终端设备切换失败时测得的源中继终端设备的测量结果是否高于中继终端选择阈值。For data item 10, the first indication information indicates whether the measurement result of the source relay terminal device measured when the terminal device fails to switch is higher than the relay terminal selection threshold.

对于中继终端选择阈值，relay终端选择阈值为网络设备配置给终端设备用于判断中继终端设备是否适合作为remote终端设备的中继设备的阈值，如果一个remote终端设备同时监测到多个relay终端的信号，remote终端设备只会从测得的relay终端设备中选择信号测量结果大于relay终端选择阈值的relay终端作为remote终端设备的中继设备。For the relay terminal selection threshold, the relay terminal selection threshold is the threshold configured by the network device to the terminal device to determine whether the relay terminal device is suitable as the relay device of the remote terminal device. If a remote terminal device detects multiple relay terminals at the same time signal, the remote terminal device will only select the relay terminal whose signal measurement result is greater than the relay terminal selection threshold from the measured relay terminal devices as the relay device of the remote terminal device.

数据项10和数据项11记录了relay终端设备的测量结果与relay终端选择阈值的关系。一种实现方式下，网络设备基于数据项10和数据项11判断连接失败的原因；另一种实现方式下，网络设备基于数据项10和数据项11优化relay终端选择阈值，Data item 10 and data item 11 record the relationship between the measurement result of the relay terminal device and the relay terminal selection threshold.

对于数据项13，指示终端设备发生切换过程失败或者无线链路失败后的重建过程中找不到任何一个满足relay终端选择阈值的relay终端设备，也可称作无适合的用于无线连接重建过程的中继终端设备(No suitable relay UE found during connection reestablishment procedure)。For data item 13, it indicates that the terminal device cannot find any relay terminal device that satisfies the relay terminal selection threshold during the re-establishment process after the handover process fails or the wireless link fails, which can also be called that there is no suitable wireless connection re-establishment process. The relay terminal equipment (No suitable relay UE found during connection reestablishment procedure).

当终端设备进行无线连接重建，且未找到合适的进行无线连接重建的中继终端设备的情况下，第一数据中包括数据项13。When the terminal device reestablishes the wireless connection and no suitable relay terminal device is found for reestablishing the wireless connection, the first data includes the data item 13 .

数据项13记录了终端设备发生切换过程失败或者无线链路失败后的重建过程中找不到任何一个满足relay终端选择阈值的relay终端设备，有可能是因为relay终端选择阈值太高，导致满足条件的relay终端找不到，因此，网络设备基于数据项13可优化relay终端选择阈值。Data item 13 records that no relay terminal device that satisfies the relay terminal selection threshold can be found in the re-establishment process after the handover process of the terminal device fails or the wireless link fails. It may be because the relay terminal selection threshold is too high, resulting in the condition The relay terminal of can not be found, therefore, the network device can optimize the relay terminal selection threshold based on the data item 13.

对于数据项14的第四测量信息，表示终端设备通过目标relay终端设备与目标网络设备建立连接后目标relay终端设备与目标网络设备之间的链路发生无线链路失败时，目标relay终端设备测量得到的小区信号测量结果。For the fourth measurement information of data item 14, it means that after the terminal device establishes a connection with the target network device through the target relay terminal device, when a wireless link failure occurs in the link between the target relay terminal device and the target network device, the target relay terminal device measures Obtained cell signal measurement results.

对于信息2，时长1的终端设备开始执行切换可以理解为：终端设备尝试与目标小区建立连接。For information 2, the fact that the terminal device starts to perform handover with duration 1 can be understood as: the terminal device attempts to establish a connection with the target cell.

示例性地，尝试建立连接行为包括终端设备向目标小区发起随机接入过程或者发送重配完成消息。终端设备尝试与目标小区建立连接的场景可包含两种场景：Exemplarily, the behavior of attempting to establish a connection includes that the terminal device initiates a random access procedure to the target cell or sends a reconfiguration complete message. Scenarios in which a terminal device attempts to establish a connection with a target cell may include two scenarios:

场景1、终端设备与目标小区通过空口直接建立连接； Scenario 1. The terminal device and the target cell directly establish a connection through the air interface;

场景2、终端设备与目标小区通过目标relay终端设备间接建立连接。Scenario 2: The terminal device indirectly establishes a connection with the target cell through the target relay terminal device.

连接失败时刻的含义：终端设备与目标网络设备之间的连接建立失败。The meaning of the connection failure moment: the connection between the terminal device and the target network device fails to be established.

连接失败场景6(对应切换失败场景9)：切换过程执行成功，终端设备与目标relay终端设备之间的链路仍然维持，但后来终端设备收到目标relay终端设备发送的失败指示信息，所述失败指示信息用于指示目标relay终端与目标网络设备之间的链路发生无线链路失败。Connection failure scenario 6 (corresponding to handover failure scenario 9): The handover process is executed successfully, and the link between the terminal device and the target relay terminal device is still maintained, but later the terminal device receives failure indication information sent by the target relay terminal device, and the The failure indication information is used to indicate that a radio link failure occurs in the link between the target relay terminal and the target network device.

其中，连接失败包括切换前的无线链路失败(即切换失败场景4至切换失败场景6中任一切换失败场景)，或者，连接失败场景2、3、5、6对应的任一连接失败场景。发生连接失败的relay终端设备可为源中继终端设备或目标中继终端设备。Wherein, the connection failure includes the wireless link failure before the handover (that is, any handover failure scene in the handover failure scene 4 to the handover failure scene 6), or any connection failure scene corresponding to the connection failure scene 2, 3, 5, or 6 .

本申请实施例中，第一消息上报的记录数据中的各信息的有益效果介绍如下：In the embodiment of the present application, the beneficial effects of each information in the record data reported by the first message are introduced as follows:

信息1记录了切换场景标识信息，可以让网络设备识别哪种切换场景出现了问题，有利于根据场景进行优化算法设计。 Information 1 records the handover scene identification information, which can allow the network device to identify which handover scene has a problem, and is beneficial to design an optimization algorithm according to the scene.

信息2记录了终端设备开始执行切换到确定发生连接失败过程经历的时长信息，有利于网络设备判断本次连接失败是否需要优化，比如，时长1记录时间很长则表示连接失败与切换关系不大(切换后很久才发生连接失败)，可能不需要优化切换参数。Information 2 records the duration information of the terminal device starting to execute the switchover and confirming the connection failure process, which is helpful for the network device to judge whether the connection failure needs to be optimized. For example, the record time of duration 1 is very long, indicating that the connection failure has little to do with the switch (connection failures occur long after the handover), there may be no need to optimize the handover parameters.

信息3记录了切换过程失败或者无线链路失败的原因信息，与信息1结合有利于网络设备知道更精细的失败场景，便于网络设备针对细分场景分开优化。Information 3 records the cause information of the handover process failure or wireless link failure. Combining with information 1, it is helpful for network devices to know more detailed failure scenarios, and it is convenient for network devices to optimize separately for subdivided scenarios.

信息4至信息6记录了relay终端设备的标识信息，便于网络设备判断relay切换过早、过迟或者relay错误切换。Information 4 to Information 6 record the identification information of the relay terminal device, which is convenient for the network device to judge whether the relay switching is too early, too late or the relay is switching incorrectly.

比如：如果终端设备记录的发生连接失败的relay终端设备的标识与源relay终端设备的标识相同，且目标中继终端设备的标识与重建过程使用的relay终端设备的标识相同，则网络设备可能判定本次失败为切换过迟；For example: if the identifier of the relay terminal device that failed to connect recorded by the terminal device is the same as the identifier of the source relay terminal device, and the identifier of the target relay terminal device is the same as the identifier of the relay terminal device used in the reconstruction process, the network device may determine that This failure is too late for switching;

再比如：如果重建过程使用的relay终端标识与源relay终端标识、目标relay终端标识均不同，则网络设备可能判定本次失败为relay错误切换；For another example: if the relay terminal ID used in the rebuilding process is different from the source relay terminal ID and the target relay terminal ID, the network device may determine that the failure is relay error switching;

再比如：如果重建过程使用的relay终端标识与源relay终端标识相同，则网络设备可能判定本次失败为切换过早。For another example: if the relay terminal identifier used in the reconstruction process is the same as the source relay terminal identifier, the network device may determine that the failure is premature handover.

信息7至信息9记录了小区和relay终端的测量结果，有利于网络设备精确判断连接失败的方向，比如，失败时目标relay终端的测量结果较差，可能说明网络设备切换过早了。Information 7 to 9 record the measurement results of the cell and the relay terminal, which is helpful for the network device to accurately determine the direction of the connection failure. For example, if the measurement result of the target relay terminal is poor at the time of failure, it may indicate that the network device switched too early.

In one implementation mode, it is helpful for the network device to accurately determine the direction of connection failure; in another implementation mode, it can assist the network device in optimizing the relay Terminal selection threshold.

信息12记录了无线链路失败的原因为切换成功后目标relay与网络设备之间的链路发生无线链路失败，与信息1合有利于网络设备知道更精细的失败场景，便于网络设备针对细分场景分开优化。Information 12 records that the reason for the wireless link failure is that the link between the target relay and the network device fails after the handover is successful. Combining with information 1 will help the network device know more detailed failure scenarios, and facilitate the network device to target detailed Separate optimization by scene.

信息13记录了终端设备发生切换过程失败或者无线链路失败后的重建过程中找不到任何一个满足relay终端选择阈值的relay终端设备，有可能是因为relay终端选择阈值太高，导致满足条件的relay终端找不到，可以辅助网络设备优化relay终端选择阈值。Information 13 records that no relay terminal device that satisfies the relay terminal selection threshold can be found during the re-establishment process after the handover process of the terminal device fails or the wireless link fails. It may be because the relay terminal selection threshold is too high, resulting in If the relay terminal cannot be found, the network device can be assisted in optimizing the relay terminal selection threshold.

信息14记录了终端设备通过目标relay终端设备与网络设备建立连接后目标relay终端设备与网络设备之间的链路发生无线链路失败时目标relay终端设备测量得到的小区信号测量结果，网络设备可以基于该信息优化relay终端判断阈值，relay终端判断阈值与relay终端选择阈值不同，其中relay终端选择阈值是remote终端使用的，relay终端判断阈值是给relay终端自己使用的，只有满足relay终端判断阈值的终端设备才能作为其他remote终端的relay终端设备，relay终端判断阈值通过网络设备配置给终端设备。Information 14 records the cell signal measurement results measured by the target relay terminal device when the link between the target relay terminal device and the network device establishes a connection between the target relay terminal device and the network device. Optimize the relay terminal judgment threshold based on this information. The relay terminal judgment threshold is different from the relay terminal selection threshold. The relay terminal selection threshold is used by the remote terminal, and the relay terminal judgment threshold is used by the relay terminal itself.
