在介绍本申请技术方案之前，下面先介绍四步随机接入过程、两步随机接入过程以及网络切片。
需要说明的是，随机接入过程通常可以由以下事件触发：
(1)初始接入(Initial Access)时建立无线连接，例如，终端设备需要从无线资源控制(Radio Resource Control，RRC)空闲态(RRC_IDLE态)进入RRC连接态(RRC_CONNECTED)，此时，该终端设备可以触发初始接入。
(2)RRC连接重建过程(RRC Connection Re-establishment procedure)，以便终端设备在无线链路失败之后重建无线连接。
(3)切换(Handover)，此时，终端设备处于连接态，终端设备需要与目标小区建立上行同步。
(4)RRC连接态下，下行数据或上行数据到达时，上行处于“失步”状态(DL or UL data arrival during RRC_CONNECTED when UL synchronisation status is"non-synchronised")。
(5)RRC连接态下，上行数据到达时，没有可用的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源用于调度请求(Scheduling Request，SR)传输(UL data arrival during RRC_CONNECTED when there are no PUCCH resources for SR available)。
(6)SR失败(SR failure)。
(7)RRC在同步配置时的请求(Request by RRC upon synchronous reconfiguration)。
(8)终端设备从RRC非激活态过渡(Transition from RRC_INACTIVE)。
(9)在SCell添加时建立时间对齐(To establish time alignment at SCell addition)。
(10)终端设备请求其他系统信息(Other System Information，OSI)。
(11)终端设备需要进行波束(Beam)失败的恢复(Beam failure recovery)。
(12)非激活态下恢复接入：RRC Resume Request。
在NR系统中，可以支持两种随机接入方式：基于竞争的随机接入方式和基于非竞争的随机接入方式。下面简单描述基于竞争的四步随机接入，如图2所示，四步随机接入包括：
步骤1，终端设备向网络设备发送随机接入前导码(Preamble，也即Msg 1)。
其中，随机接入前导码也可以称为前导码、随机接入前导码序列、前导码序列等。
具体而言，终端设备可以选择物理随机接入信道(Physical Random Access Channel，PRACH)资源，PRACH资源可以包括时域资源、频域资源和码域资源。网络设备通过广播系统信息块(System Information Block，SIB)1向终端设备发送随机接入相关参数，其中随机接入公共配置信息元素(RACH-ConfigCommon IE)中的针对同步信号块(Synchronization Signal Block，SSB)的参考信号接收功率(Reference Signal Receiving Power，RSRP)门限值(rsrp-ThresholdSSB)用于终端设备进行SSB选择，终端设备将每个SSB下的RSRP测量结果与rsrp-ThresholdSSB进行对比，选择测量值高于所配置门限值的SSB进行接入，若没有满足配置门限值的SSB，则从全部SSB中随机选择一个进行接入。每个SSB对应一组随机接入前导码资源和随机接入时机(RACH Occasion，RO)资源，终端设备从选定的SSB中用于基于竞争的随机接入资源中进行随机选择，将Preamble索引(PREAMBLE_INDEX)设置为选定的随机接入Preamble。网络设备可以根据Preamble估计其与终端设备之间的传输时延并以此校准上行定时(timing)，以及可以大体确定终端设备传输Msg 3所需要的资源大小。为了让网络设备可以更准确的了解到待传输的Msg 3的大小以分配合适的上行资源，将Preamble分为Preamble组(group)A和Preamble group B，若随机接入资源中存在Preamble group B，终端设备可以根据Msg 3的大小以及路损(pathloss)对Preamble group进行选择。
步骤2，网络设备向终端设备发送随机接入响应(Random Access Response，RAR，也即Msg 2)
终端设备向网络设备发送Preamble后，可以开启一个随机接入响应窗口(ra-ResponseWindow)，在该ra-ResponseWindow内根据随机访问无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)检测对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)。若终端设备检测到RA-RNTI加扰的PDCCH后，可以获得该PDCCH调度的物理下行共 享信道(Physical Downlink Shared Channel，PDSCH)。其中，该PDSCH中包括Preamble对应的RAR。
RA-RNTI根据发送Preamble的PRACH的时频位置计算得到，因此如果多个终端设备在同一个RO上发送Preamble，则对应的RAR复用在同一个RAR媒体接入控制协议数据单元(Media Access Control Protocol Data Unit，MAC PDU)中。若终端成功接收到与发送Preamble的RO资源对应的RA-RNTI加扰的PDCCH，并且RAR中包含一个MAC子PDU(subPDU)所携带的随机访问序列标识符(Random Access Preamble Identifier，RAPID)与上述Msg 1中选择的PREAMBLE_INDEX相对应，则RAR接收成功，终端可解码得到定时提前命令(Timing Advance Command，TAC)，上行授权资源(UL Grant)和临时小区RNTI(Temporary Cell Radio Network Temporary Identity，TC-RNTI)，进行Msg 3。
若在ra-ResponseWindow运行期间没有接收到与发送Preamble的RO资源对应的RA-RNTI加扰的PDCCH，或接收到了RA-RNTI加扰的PDCCH，但RAR中不包含与PREAMBLE_INDEX对应的MAC subPDU，上述两种情况出现时则认为RAR接收失败，此时，若Preamble的传输次数没有超过网络配置的最大传输次数(preambleTransMax)，终端设备需要对Msg 1进行重传，若Preamble的传输次数超过了网络配置的最大传输次数(preambleTransMax)，终端设备向上层上报随机接入问题。
步骤3，终端设备发送Msg 3。
终端设备在收到RAR消息后，判断该RAR是否为属于自己的RAR消息，例如终端设备可以利用前导码索引进行核对，在确定是属于自己的RAR消息后，可以在RRC层产生Msg 3，并向网络设备发送Msg 3，其中需要携带终端设备的标识信息等。
其中，Msg 3主要用于通知网络设备该随机接入的触发事件。针对不同的随机接入触发事件，终端设备在步骤3中发送的Msg 3可以包括不同的内容。
例如，对于初始接入的场景，Msg 3可以包括RRC层生成的RRC连接请求消息(RRC Setup Request)。此外，Msg 3还可以携带例如终端设备的5G-服务临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)或随机数等。
又例如，对于RRC连接重建场景，Msg 3可以包括RRC层生成的RRC连接重建请求消息(RRC Reestabilshment Request)。此外，Msg 3还可以携带例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)等。
又例如，对于切换场景，Msg 3可以包括RRC层生成的RRC切换确认消息(RRC Handover Confirm)，其携带终端设备的C-RNTI。此外，Msg 3还可携带例如缓冲状态报告(Buffer Status Report，BSR)等信息。对于其它触发事件例如上/下行数据到达的场景，Msg 3至少可以包括终端设备的C-RNTI。
步骤4，网络设备向终端设备发送冲突解决消息(contention resolution)，即Msg 4。
网络设备向终端设备发送Msg 4，终端设备正确接收Msg 4完成竞争解决(Contention Resolution)。例如在RRC连接建立过程中，Msg 4中可以携带RRC连接建立消息。
由于步骤3中的终端设备可以在Msg 3中携带自己唯一的标识，从而网络设备在竞争解决机制中，会在Msg4中携带终端设备的唯一标识以指定竞争中胜出的终端设备。而其它没有在竞争解决中胜出的终端设备将重新发起随机接入。
应理解，在本申请实施例中，竞争冲突解决可以有两种方式：
方式一、如果终端设备在Msg 3携带了C-RNTI，则Msg 4可以用C-RNTI加扰的PDCCH调度。
方式二、如果终端设备没有在Msg 3中携带C-RNTI，比如是初始接入，则Msg 4可以用TC-RNTI加扰的PDCCH调度。此时，竞争冲突的解决可以是通过终端设备接收Msg 4的PDSCH，获得冲突解决ID，通过匹配该冲突解决ID与Msg 3中中的公共控制信道(Common Control Channel，CCCH)服务数据单元(Service Data Unit，SDU)来判断是否解决冲突。
NR Rel-16版本标准化过程中正在研究两步随机接入过程。与Rel-15版本中的四步随机接入过程相比，两步随机接入可以提高时延，同时也能降低信令开销。目前确定的两步随机接入的基本步骤是：
1.终端向网络发送MsgA，MsgA传输四步随机接入的Msg1+Msg3；
2.网络给终端发送MsgB，MsgB传输四步随机接入的Msg2+Msg4。终端发送MsgA之后,开启一个MsgB的接收窗，在该接收窗内监测并接收MsgB。
对于四步随机接入过程，终端设备在发送Msg1之后，将在随机接入响应时间窗(ra-ResponseWindow)内监听RA-RNTI加扰的PDCCH，以接收对应的RAR。如果在此时间窗内UE还没有接收到随机接入响应，则认为本次随机接入失败，终端设备会重新发送Msg1。当终端设备发送Msg1的次数达到一定门限后，终端设备会向高层指示出现了随机接入的问题。随机接入响应时间窗起始于终端设备发送Msg1之后的第一个PDCCH资源(occasion)，ra-ResponseWindow的窗长 由网络配置，ra-ResponseWindow可支持的最大值为10ms的窗长。
类似地，终端设备在发送MsgA之后也会开始启动一个MsgB的接收时间窗，终端设备在这个接收时间窗内监听来自网络的MsgB。如果终端设备在该接收窗内没有接收到MsgB，则终端设备认为本次随机接入失败。
网络切片是由接入网(Radio Access Network，RAN)部分和核心网(Core Network，CN)部分组成。不同的网络切片具有不同的网络切片选择辅助信息(Network Slice Selection Assistance Information，NSSAI)。
网络对网络切片的支持依赖于将隶属于不同网络切片和不同的传输性能要求(如可靠性、传输时延、传输速率等)的数据通信由不同的协议数据单元(Protocol Data Unit，PDU)会话(session)承载。
例如，网络会将增强移动超宽带(Enhance Mobile Broadband，eMBB)和高可靠低时延通信(Ultra-Reliable and Low Latency Communication，URLLC)业务在不同的PDU session上进行承载。每个不同的PDU session可以具有多个服务质量流(Quality of Service flow，QoS Flow)。
在下行方向，核心网的非接入层(Non-Access Stratum，NAS)服务数据流(Service data flow，SDF)模板(template)将来自应用层不同的数据包进行分类映射至不同PDU session里的不同QoS Flow，并且使其在不同的PDU session中发送给RAN。RAN根据QoS Flow的ID信息将其映射至不同的数据无线承载(Data Radio Bearer，DRB)在空口上发送给UE。同理，对于上行数据，也可以采用类似的操作。
如上所述，对于RAN网络切片，网络设备在接收到Msg 5(即随机接入过程之后的第一条下行消息，例如：RRC连接建立完成消息)之后，网络设备才能获取到终端设备需求的网络切片信息，而终端设备需求的网络切片，可能并不是网络设备支持的网络切片，或者，虽然是网络设备支持的网络切片，但是该网络切片超负荷了，这种情况下，网络设备只能在接收到Msg 5之后发送RRC Connection Release消息，使得终端设备重新选择合适的小区，从而造成了终端设备的业务时延。
为了解决上述技术问题，本申请通过终端设备在随机接入过程中向网络设备发送终端设备是否支持网络切片，和/或，终端设备支持的网络切片的信息，来解决上述技术问题。
以下通过具体实施例详述本申请的技术方案。
图3为本申请一实施例提供的无线通信方法交互流程图，该方法包括如下步骤：
步骤S310：终端设备向网络设备发送第一切片相关信息。
其中，第一切片相关信息携带在随机接入过程中。
