具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是根据本公开的实施例示出的一种随机接入控制方法的示意流程图。本实施例所示的方法可以适用于用户设备，例如手机、平板电脑、可穿戴设备(手环、手表、头盔)等，所述用户设备可以与基站进行通信，例如可以基于LTE(Long Term Evolution，长期演进)进行通信，也可以基于NR(New Radio，新空口)进行通信。
在相关技术中，当在进行随机接入过程中接收到针对随机接入过程关联的小区的带宽部分切换命令，用户设备可以选择忽略带宽部分切换命令，也可以选择停止正在进行的随机接入过程，然后根据带宽部分切换指令切换带宽部分，在切换带宽部分后继续之前停止的随机接入过程。
根据目前的协议规定，若随机接入在SpCell(包括主小区PCell和主辅小区PScell)上发起，需要随机接入过程关联的下行带宽部分和随机接入过程关联的上行带宽部分具有相同的ID。
然而，当用户设备选择停止正在进行的随机接入过程时，根据带宽部分切换指令切换了带宽部分，若该带宽部分切换命令是针对随机接入过程关联的小区的，那么会导致切换后的带宽部分，与切换前用户设备进行随接入过程所使用的带宽部分不同。这会使得切换后的带宽部分相对于切换前的带宽部分ID发生变化。
当用户设备在切换带宽部分后继续之前停止的随机接入过程，若随机接入在SpCell上发起，由于切换后的带宽部分相对于切换前的带宽部分ID发生变化，用户设备为了继续之前停止的随机接入过程，就需找到与之前进行的随机接入过程关联的带 宽部分具有相同ID的带宽部分，从而又会切换回切换前的带宽部分继续进行随机接入，导致根据带宽切换指令做出的切换操作相当于并未被执行，浪费了用户设备的资源。
需要说明的是，一般而言，随机接入过程关联的上行带宽部分，可以是指用户设备用于发送随机接入消息(例如MSG1)的上行带宽部分，随机接入过程关联的下行带宽部分，可以是指用户设备用于接收随机接入消息(例如MSG2)的下行带宽部分。
进一步地，在某些情况下，例如对于非成对频谱而言，载波上的上行带宽部分和下行带宽部分是同一个，在这种情况下，若载波的下行带宽部分与随机接入过程关联，那么该载波的上行带宽部分也与随机接入过程关联。
如图1所示，所述随机接入控制方法可以包括以下步骤：
在步骤S1中，在进行随机接入过程中，若接收到针对所述随机接入过程关联的小区的带宽部分切换命令，判断所述随机接入过程是否成功。
在一个实施例中，随机接入过程关联的小区，可以包括用户设备向基站发送随机接入的消息(例如MSG1，其中包含随机接入的前导码)时所在的小区，也可以包括用户设备接收基站发送的随机接入的消息(例如MSG2，其中包含随机接入响应，也即Random Access Response，简称为RAR)时所在的小区。
在一个实施例中，带宽部分切换指令(BWP switching)可以由基站通过PDCCH(物理下行控制信道)发送，这种情况下带宽部分切换指令可以称为PDCCH for BWP switching。
在步骤S2中，若所述随机接入过程未成功，停止所述随机接入过程；
在步骤S3中，根据所述带宽部分切换命令切换带宽部分，且不在切换后的带宽部分继续所述随机接入过程。
根据本公开的实施例，用户设备在进行随机接入的过程中，若接收到针对随机接入过程关联的小区的带宽部分切换命令，而随机接入过程未成功，也即随机接入过程仍在进行中，那么可以停止随机接入过程，然后根据带宽部分切换命令切换带宽部分，并且不在切换后的带宽部分继续所述随机接入过程。
据此，可以避免相关技术中为了继续之前停止的随机接入过程，而导致根据带 宽切换指令做出的切换操作相当于并未被执行，浪费用户设备的资源的情况，从而确保带宽切换指令切实地得到执行，用户设备能够通过切换后的带宽部分继续通信。
图2是根据本公开的实施例示出的另一种随机接入控制方法的示意流程图。如图2所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S4中，在停止所述随机接入过程之前，判断所述带宽部分切换命令是否用于将所述随机接入过程相关的下行带宽部分切换到另一个下行带宽部分；
其中，在所述带宽部分切换命令用于将所述随机接入过程相关的下行带宽部分切换到另一个下行带宽部分的情况下，若所述随机接入过程未成功，停止所述随机接入过程。
在一个实施例中，随机接入过程并未结束，一般情况下意味着用户至少没有接收到随机接入的第四条消息(MSG4)，所以在继续随机接入时，用户设备至少需要用到下行带宽部分来接收MSG4，而并不一定需要用到上行带宽部分向基站上行传输。因此，若用户设备根据带宽部分切换指令切换了随机接入过程相关的下行带宽部分，就很可能导致上述相关技术中的问题，而若用户设备根据带宽部分切换指令切换的并不是随机接入过程相关的下行带宽部分，则不一定会导致上述相关技术中的问题。
因此，可以判断所述带宽部分切换命令是否用于将所述随机接入过程相关的下行带宽部分切换到另一个下行带宽部分，在带宽部分切换命令用于将所述随机接入过程相关的下行带宽部分切换到另一个下行带宽部分的情况下，也即很可能导致相关技术中的问题时，才按照图1实施例执行步骤S2和步骤S3；而在其他情况下，则可以按照相关技术中的逻辑，在切换带宽部分后，继续之前停止的随机接入过程。从而在确保带宽切换指令切实地得到执行的基础上，减少对用户设备执行动作逻辑的调整。
图3是根据本公开的实施例示出的又一种随机接入控制方法的示意流程图。如图3所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S5中，在停止所述随机接入过程之前，判断所述随机接入过程关联的小区是否为主小区或主辅小区；
其中，在所述随机接入过程关联的小区为主小区或主辅小区的情况下，若所述随机接入过程未成功，停止所述随机接入过程。
在一个实施例中，如上述相关技术所述，当随机接入在主小区或主辅小区(也即SpCell)上发起时，才可能引发根据带宽切换指令做出的切换操作相当于并未被执 行，浪费用户设备的资源的问题。
因此，可以判断所述随机接入过程关联的小区是否为主小区或主辅小区，在所述随机接入过程关联的小区为主小区或主辅小区的情况下，也即可能导致相关技术中的问题时，才按照图1实施例执行步骤S2和步骤S3；而在其他情况下，则可以按照相关技术中的逻辑，在切换带宽部分后，继续之前停止的随机接入过程。从而在确保带宽切换指令切实地得到执行的基础上，减少对用户设备执行动作逻辑的调整。
图4是根据本公开的实施例示出的又一种随机接入控制方法的示意流程图。如图4所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S6中，在停止所述随机接入过程之前，判断所述带宽部分切换指令是否用于切换上行带宽部分，以及切换后的带宽部分是否被配置有随机接入资源；
其中，在带宽部分切换指令用于切换上行带宽部分，且切换后的带宽部分未被配置随机接入资源的情况下，若所述随机接入过程未成功，停止所述随机接入过程。
在相关技术中，当带宽部分切换指令是用于切换上行带宽部分，但是切换后的带宽部分没有被配置随机接入资源(PRACH资源)，在这种情况下，若用户设备继续之前停止的随机接入过程，在使用切换后的上行带宽部分时，就无法进行随机接入，为了继续随机接入，就不得不切换到切换前的上行带宽部分，这也会导致根据带宽切换指令做出的切换操作相当于并未被执行，浪费了用户设备的资源。
如上述相关技术所述，当带宽切换指令用于切换上行带宽部分，且切换后的带宽部分未被配置随机接入资源时，才可能引发根据带宽切换指令做出的切换操作相当于并未被执行，浪费用户设备的资源的问题。
因此，根据本实施例，可以判断所述带宽部分切换指令是否用于切换上行带宽部分，以及切换后的带宽部分是否被配置有随机接入资源，在判断所述带宽部分切换指令用于切换上行带宽部分，且切换后的带宽部分未被配置有随机接入资源的情况下，也即可能导致相关技术中的问题时，才按照图1实施例执行步骤S2和步骤S3；而在其他情况下，则可以按照相关技术中的逻辑，在切换带宽部分后，继续之前停止的随机接入过程。从而在确保带宽切换指令切实地得到执行的基础上，减少对用户设备执行动作逻辑的调整。
图5是根据本公开的实施例示出的又一种随机接入控制方法的示意流程图。如图5所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S7中，在停止所述随机接入过程之前，判断切换后的上行带宽部分和切换后的下行带宽部分是否具有相同的标识；
其中，在切换后的上行带宽部分和切换后的下行带宽部分具有不同的标识的情况下，若所述随机接入过程未成功，停止所述随机接入过程。
如前述相关技术所指出的，当随机接入过程关联的下行带宽部分和随机接入过程关联的上行带宽部分具有不同的ID，才可能引发根据带宽切换指令做出的切换操作相当于并未被执行，浪费用户设备的资源的问题。
因此，根据本实施例，对于带宽部分切换指令用于切换上行带宽部分和下行带宽部分的情况，可以判断切换后的上行带宽部分和下行带宽部分是否具有相同的ID，在判断切换后的上行带宽部分和下行带宽部分是否具有相同的ID的情况下，也即可能导致相关技术中的问题时，才按照图1实施例执行步骤S2和步骤S3；而在其他情况下，则可以按照相关技术中的逻辑，在切换带宽部分后，继续之前停止的随机接入过程。从而在确保带宽切换指令切实地得到执行的基础上，减少对用户设备执行动作逻辑的调整。
图6是根据本公开的实施例示出的又一种随机接入控制方法的示意流程图。如图6所示，在图5所示实施例的基础上，所述方法还包括：
在步骤S8中，若切换后的上行带宽部分和切换后的下行带宽部分具有相同的标识，且所述随机接入过程因波束失败恢复而触发，判断所述随机接入过程相关的切换前的带宽部分与切换后的带宽部分是否具有相同的无线链路检测配置参数；
其中，在所述随机接入过程相关的切换前的带宽部分与切换后的带宽部分具有不同的无线链路检测配置参数的情况下，若所述随机接入过程未成功，停止所述随机接入过程。
在一个实施例中，在某些情况下，即使切换后的上行带宽部分和切换后的下行带宽部分具有相同的标识，仍有可能存在问题。例如随机接入过程因波束失败恢复(Beam Failure Recovery，简称BFR)而触发，在这种情况下，用户设备需要根据无线链路检测(radio link monitoring，简称RLM)配置参数对波束进行测量，以确定波束质量，进而根据确定的波束质量可以确定波束失败恢复时选择那个波束。
而当切换前的带宽部分与切换后的带宽带部分具有不同的无线链路检测配置参数时，用户设备基于切换前的带宽部分的无线链路检测配置参数确定的可以选择的 波束，与根据切换后的带宽带部分的无线链路检测配置参数确定的可以选择的波束有所不同，这就会导致用户设备进行波束失败恢复时，不知道选择哪个波束，而在这种情况下若继续之前停止的随机接入过程，由于不知道选择哪个波束而无法完成波束失败恢复，也就无法继续之前停止的随机接入过程。
因此，根据本实施例，对于随机接入过程因波束失败恢复而触发的情况，可以判断所述随机接入过程相关的切换前的带宽部分与切换后的带宽部分是否具有相同的无线链路检测配置参数，在随机接入过程相关的切换前的带宽部分与切换后的带宽部分是否具有不同的无线链路检测配置参数的情况下，也即可能导致上述无法继续之前停止的随机接入过程，才按照图1实施例执行步骤S2和步骤S3，以避免用户设备因为无法继续之前停止的随机接入过程而出现问题；而在其他情况下，则可以按照相关技术中的逻辑，在切换带宽部分后，继续之前停止的随机接入过程。从而在避免用户设备因为无法继续之前停止的随机接入过程而出现问题的基础上，减少对用户设备执行动作逻辑的调整。
需要说明的是，上述无线链路检测配置参数，可以包括一下至少之一：
无线链路检测参考符号(RLM RS)配置、不同的波束失败检测定时器(beam Failure Detection Timer)、不同的波束失败实例最大数目(beam Failure Instance Max Count)。
图7是根据本公开的实施例示出的又一种随机接入控制方法的示意流程图。如图7所示，在图5所示实施例的基础上，所述方法还包括：
在步骤S9中，若切换后的上行带宽部分和切换后的下行带宽部分具有相同的标识，且所述随机接入过程因波束失败恢复而触发，判断切换后的下行带宽部分是否关联可用的波束测量结果；
其中，在切换后的下行带宽部分未关联可用的波束测量结果的情况下，若所述随机接入过程未成功，停止所述随机接入过程。
在一个实施例中，在某些情况下，即使切换后的上行带宽部分和切换后的下行带宽部分具有相同的标识，仍有可能存在问题。例如随机接入过程因波束失败恢复而触发，在这种情况下，用户设备需要根据可用的波束测量结果确定波束质量，进而根据确定的波束质量可以确定波束失败恢复时选择那个波束。
而当切换后的下行带宽部分未关联可用的波束测量结果时，用户设备基于切换 后的下行带宽部分就查询不到可用的波束测量结果，这就会导致用户设备进行波束失败恢复时，不知道选择哪个波束，而在这种情况下若继续之前停止的随机接入过程，由于不知道选择哪个波束而无法完成波束失败恢复，也就无法继续之前停止的随机接入过程。
因此，根据本实施例，对于随机接入过程因波束失败恢复而触发的情况，可以判断切换后的下行带宽部分是否关联可用的波束测量结果，在切换后的下行带宽部分未关联可用的波束测量结果的情况下，也即可能导致上述无法继续之前停止的随机接入过程，才按照图1实施例执行步骤S2和步骤S3，以避免用户设备因为无法继续之前停止的随机接入过程而出现问题；而在其他情况下，则可以按照相关技术中的逻辑，在切换带宽部分后，继续之前停止的随机接入过程。从而在避免用户设备因为无法继续之前停止的随机接入过程而出现问题的基础上，减少对用户设备执行动作逻辑的调整。
需要说明的是，判断切换后的下行带宽部分是否关联可用的波束测量结果，所判断波束测量结果可以是指不同的测量结果，例如在随机接入为竞争性的随机接入(contention based random access，简称CBRA)时，波束测量结果可以是指SSB-RSRP(Reference Signal Receiving Power，参考信号接收功率)测量结果，在随机接入为非竞争的随机接入(contention free random access，简称CFRA)时，测量结果可以是SSB-RSRP测量结果和/或CSI(Channel State Information，信道状态信息)-RSRP测量结果。
需要说明的是，SSB的全称为Synchronization Signal Block，其具体是表示Synchronization/PBCH(物理广播信道)block，因为Synchronization Signal和PBCH在物理层可以统一打包一并处理，因此将这两者统一称为SSB。
其中，Synchronization Signal可以包括PSS(主同步信号)和SSS(辅同步信号)，PBCH则可以包括PBCH DMRS(解调参考信号)和PBCH数据。
