After sending the Msg1, the terminal calculates the identification information of the network-side dispatch Msg2 (ie, RA-RNTI (Random Access Radio Network Temporary Identity) of the random access wireless network) based on the sending time and frequency of Msg1.

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
在进行本公开实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
随机接入过程主要分为：非竞争随机接入和竞争随机接入。其中，竞争随机接入过程如图2所示，主要分为四步：
Msg1(消息一)：终端选择随机接入资源并利用该随机接入资源向基站 发送所选的随机接入信号(例如，preamble)。终端在发送Msg1后，根据Msg1的发送时间和频率的位置计算网络侧调度Msg2的标识信息(即RA-RNTI(Random Access Radio Network Temporary Identity，随机接入无线网络临时标识))。终端在发送Msg1后，在一个固定窗口内(即RAR window(Random Access Response window随机接入响应窗口))监听下行信道以获取网络侧的反馈信息Msg2。
Msg2(消息二)：基站接收到Msg1，计算TA(定时提前量)，并向终端发送随机接入响应，随机接入响应中可能包含：Msg1RAPID(即标识信息)；Timing Advance Command(即上行定时提前量信息)；UL Grant(即上行发送授权信息)；Backoff Indicator(即回退信息)；Temporary C-RNTI(即临时终端标识信息)。如果终端接收RAR(Random Access Response，随机接入响应)失败或在RAR中未检出自己所发Msg1对应的RAPID，则根据RAR中指示的回退信息(如RAR中包含)，确定下次发送随机接入的时刻。
Msg3(消息三)：终端在Msg2指定的UL grant上发送上行传输，不同随机接入原因Msg3上行传输的内容不同，比如对于初始接入，Msg3传输的是RRC(Radio Resource Control，无线资源控制)连接建立请求。终端在发送Msg3后会启动竞争解决定时器。如果竞争解决定时器超时前，Msg4都没有接收成功过，则UE认为Msg4接收失败。
Msg4(消息四)：竞争解决消息，终端根据Msg4可以判断随机接入是否成功。
在NR中，小区常工作在高频段，信号在空间传输损耗比较大。如果由单一波束(beam)覆盖整个小区，将要求基站支持很高的发送功率。为了解决这个问题，NR cell可以用多个波束覆盖一个小区，多个波束分时工作。例如，一个扇形小区由8个波束进行覆盖。8个波束以时分方式发送，每个时刻小区只发送一个波束。
UE根据参考符号来识别不同的波束，存在两种参考符号：SSB(Synchronization Signal Block，同步信号块)和CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)。UE可以根据网络的配置确定自己所要监听的参考符号，并可以根据收听到的参考符号，确定自 己所处位置被哪一个/几个波束所覆盖。
简化的两步竞争随机接入方法可以降低四步竞争随机接入的时延，同时可以适用于激活态UE进行小数据传输。但是，目前对两步竞争随机接入中Msg1所需的传输资源还没有解决方案。
本公开针对相关技术中对简化的两步竞争随机接入中Msg1所需的传输资源没有确定方案，导致网络通信流程不完整，无法保证网络通信的可靠性的问题，提供一种随机接入方法、终端及网络设备。
如图3所示，本公开实施例提供一种随机接入方法，应用于终端，包括：
步骤301，获取目标随机接入的配置信息；
需要说明的是，该目标随机接入指的是简化的两步竞争随机接入。
步骤302，根据所述配置信息，确定发送消息一的第一物理上行共享信道PUSCH资源；
步骤303，在第一PUSCH资源上，发送目标随机接入的消息一。
通过根据简化的两步竞争随机接入的配置信息，确定发送消息一的第一PUSCH资源，该第一PUSCH资源主要用户进行用户面数据的传输，然后在进行简化的两步竞争随机接入的消息一的发送，以此明确了简化的两步竞争随机接入中发送消息一的第一PUSCH资源的方式。
进一步需要说明的是，该配置信息包括以下信息中的至少一项：
A1、终端监听的至少一个参考信号；
需要说明的是，该至少一个参考信号包括：至少一个同步信号块(SSB)和/或至少一个信道状态信息参考信号(CSI-RS)。
此A1信息中的至少一个参考信号指的是网络设备为终端配置的终端需要监听的至少一个参考信号。
A2、参考信号与PUSCH资源的关联关系；
需要说明的是，网络设备可以为终端配置一个PUSCH资源，也可以配置多个PUSCH资源，具体的，所述PUSCH资源包括：免授权(grant free)资源和/或为所述目标随机接入预配置的资源，需要说明的是，该预配置的资源指的是网络设备为简化的两步竞争随机接入预留的资源。
需要说明的是，该关联关系包括以下信息中的至少一项：
A21、参考信号与PUSCH资源为一对一的关系；
即一个参考信号只与一个PUSCH资源相关联，例如，当终端监听的参考信号包括：SSB1和CSI-RS0时，SSB1对应PUSCH资源0，CSI-RS0对应PUSCH资源1。
A22、一个PUSCH资源对应至少一个参考信号；
需要说明的是，此时PUSCH资源与参考信号的关联关系为一对多的关系，即一个PUSCH资源与多个参考信号对应；例如，当终端监听的参考信号包括：SSB2和SSB3时，SSB2对应PUSCH资源2，SSB3也对应PUSCH资源2。
A23、一个参考信号对应至少一个PUSCH资源。
需要说明的是，此时参考信号与PUSCH资源的关联关系为一对多的关系，即一个参考信号与多个PUSCH资源对应；例如，当终端监听的参考信号包括：CSI-RS1和CSI-RS2时，CSI-RS1对应PUSCH资源3和PUSCH资源4，CSI-RS2对应PUSCH资源5和PUSCH资源6。
这里需要说明的是，在一个配置信息中可以采用以上关联方式中的任意一个，也可以选择某几个，也可以同时选用上述三种关联方式，例如，当终端监听的参考信号包括：SSB4、SSB5、SSB6和CSI-RS3时，其中，SSB4对应PUSCH资源7，SSB5和SSB6对应PUSCH资源8，CSI-RS3对应PUSCH资源9和PUSCH资源10。
A3、终端在所述至少一个参考信号中进行第一参考信号选择时所依据的性能指标；
需要说明的是，该性能指标包括：以下信息中的一项：
参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)和信噪比(SINR)；
即在一次配置中，网络设备指示终端只采用一种性能指标进行第一参考信号的选择，该性能指标为RSRP、RSRQ和SINR中的任意一项。
A4、终端在所述至少一个参考信号中进行第一参考信号选择时所依据的针对所述性能指标的预设门限值。
需要说明的是，该预设门限值指的是选择第一参考信号时，性能指标所依据的门限标准。例如，当采用RSRP作为选择第一参考信号的性能指标时， 当存在性能指标的实质测量值大于或等于预设门限值的参考信号时，只将性能指标的实质测量值大于或等于预设门限值的参考信号选择为第一参考信号。
进一步需要说明的是，步骤101可以采用如下方式中的至少一项实现：
B1、接收网络设备通过系统广播消息发送的目标随机接入的配置信息；
B2、接收网络设备通过无线资源控制(RRC)释放消息发送的目标随机接入的配置信息。
例如，在一次配置中，网络设备可以选择将配置信息中包含的信息全部通过系统广播消息进行发送，或者全部通过RRC释放消息进行发送；网络设备也可以选择将配置信息中一部分信息通过系统广播消息进行发送，将另一部分信息通过RRC释放消息进行发送。
进一步需要说明的是，步骤102的具体实现方式为：确定第一参考信号；在与所述第一参考信号相关联的PUSCH资源中确定一个PUSCH资源，作为发送消息一的第一PUSCH资源。
此实现过程为：终端先确定选择使用哪个参考信号来确定PUSCH资源，在确定了参考信号后，只需在与该参考信号关联的PUSCH资源进行发送消息一的PUSCH资源的确定即可。
具体地，确定第一参考信号的方式包括：
C1、当存在至少一个参考信号的性能指标大于或等于预设门限值时，在所述性能指标大于或等于预设门限值的至少一个参考信号中确定一个参考信号，作为第一参考信号；
在此种情况下，需要说明的是，当只有一个参考信号的性能指标大于或等于预设门限值时，只需将该参考信号确定为第一参考信号即可；当存在至少两个参考信号的性能指标大于或等于预设门限值时，在性能指标大于或等于预设门限值的所述至少两个参考信号中，确定一个作为第一参考信号，此时选择第一参考信号的规则可以为：在性能指标大于或等于预设门限值的所述至少两个参考信号中，随机选择一个作为第一参考信号，或者，在性能指标大于或等于预设门限值的所述至少两个参考信号中选择满足第一预设条件的一个作为第一参考信号。
具体地，该第一预设条件包括以下条件中的至少一项：
时域小于或等于第一预设阈值；
频域小于或等于第二预设阈值。
需要说明的是，此处的时域可以是参考信号所关联的RO(random occasion，随机机会)对应的时域，此处的频域指的是参考信号所关联的RO对应的频域；按照该第一预设规则选择的是最早可用的一个参考信号，即将时域最早的RO和/或频域最早的RO对应的参考信号作为最早可用的参考信号。
C2、当不存在参考信号的性能指标大于或等于预设门限值时，在网络设备为终端配置的参考信号中确定一个参考信号，作为第一参考信号；
需要说明的是，在此种情况下，终端可以在网络设备为终端配置的参考信号中随机确定一个作为第一参考信号，或者终端可以在网络设备为终端配置的参考信号中选择满足第一预设条件的一个作为第一参考信号；需要说明的是，该第一预设条件与上述的第一预设条件的含义相同，即在此种情况下，终端选择的是最早可用的一个参考信号。
在确定第一参考信号后，便需要依据该第一参考信号进行第一PUSCH资源的确定，具体地，所述在与所述第一参考信号相关联的PUSCH资源中确定一个PUSCH资源，作为发送消息一的第一PUSCH资源，包括：
D1、当所述第一参考信号与一个PUSCH资源相关联时，将所述第一参考信号对应的PUSCH资源确定为第一PUSCH资源；
需要说明的是，当第一参考信号只关联一个PUSCH资源时，因为没有可以选择的余地，所以就将此PUSCH资源作为第一PUSCH资源即可。
D2、当所述第一参考信号与至少两个PUSCH资源相关联时，在与所述第一参考信号相关联的至少两个PUSCH资源中选择一个目标PUSCH资源，作为第一PUSCH资源；
需要说明的是，所述目标PUSCH资源为与所述第一参考信号相关联的至少两个PUSCH资源中随机的一个，或所述目标PUSCH资源为与所述第一参考信号相关联的至少两个PUSCH资源中满足第二预设条件的PUSCH资源；即当第一参考信号关联多个PUSCH资源时，终端可以在多个PUSCH资源随机选择一个作为第一PUSCH资源，也可以在多个PUSCH资源中选择满足第 二预设条件的PUSCH资源作为第一PUSCH资源。
具体地，该第二预设条件包括：时域小于或等于第三预设阈值，需要说明的是，此处的时域指的是PUSCH资源所对应的时域，即在此种情况下，终端选择的是最早可用的PUSCH资源作为第一PUSCH资源。
需要说明的是，本公开实施例可以应用在NR以及后续演进的通信系统终。
本公开实施例，使得终端可以基于网络侧配置的SSB(和/或CSI-RS)与PUSCH资源的关联关系以及基于诸如RSRP的SSB(和/或CSI-RS)选择方法选择用于传输简化的两步竞争随机接入消息一所需的PUSCH资源，相比较于四步竞争随机接入降低了终端的接入时延，同时可在PUSCH资源上携带用户面数据，降低了终端状态转换所需的信令开销。
