具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
首先，对本申请实施例中涉及的名词进行简单介绍：
随机接入过程：
终端设备在有上行数据发送、接收下行数据和做跟踪区域更新等情景下需要进行随机接入。随机接入分为两种：基于碰撞的随机接入过程和免于碰撞的随机接入过程。
在基于碰撞的随机接入过程中，终端设备在一个随机接入时频资源上(RACH Occasion，RO)上使用一个公共的随机接入前导码(RACH preamble)发送msg1。之后，终端用随机接入无线网络临时标识符(Random Access RNTI，RA-RNTI)在物理下行控制信道(Physical Downlink Control Channel，PDCCH)上监听网络关于随机接入响应(Random Access Response，RAR)的PDCCH指示信息。结合参考图1，其示出了一个包括媒体接入控制(Medium Access Control，MAC)RAR的MAC协议数据单元(Protocol Data Unit，PDU)。
当侦测到关于RAR的PDCCH指示信息后，终端设备会在PDCCH指示信息给出的时频位置上解码RAR。如果RAR中含有终端设备发送的随机接入前导码信息，终端设备继而会应用RAR中与该随机接入前导码对应的信息进而发送Msg3。结合参考图2，其示出了一个RAR的示意图。RAR中包括上行调度授权(UL Grant)。
在包含有RRCSetupRequest等无线资源控制(Radio Resource Control，RRC)命令的msg3中，终端设备需要携带有自身UE ID。如果在具有众多终端设备做随机接入的情况下，很有可能会有其他终端设备在UL Grant指示的时频位置上也发送msg3(携带该终端设备的UE ID)尝试接入网络。该情况下，终端设备之间会发生随机接入碰撞，网络设备在msg4中只会携带有其中一个终端设备的ID允许其接入网络。
结合参考图3。终端设备1和终端设备2发生随机接入碰撞，终端设备1随机接入成功，而终端设备2随机接入失败。
网络切片：
网络切片是由无线接入网(Radio Access Network，RAN)部分和核心网(Core Network，CN)部分组成。通信网络对网络切片的支持依赖于将隶属于不同网络切片的数据通信由不同的协议数据单元会话(PDUsession)承载。在实现中，网络会将移动宽带增强(enhanced Mobile Broadband，eMBB)和超高可靠超低时延通信(Ultra-Reliable and Low Latency Communication，URLLC)的业务在不同的PDU session上进行承载。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)和不同的传输性能要求，如可靠性、传输时延、传输速率等。每个不同的PDU session可以具有多个服务质量流(Qos flow)。
结合参考图4，在具体通信中，在下行方向，首先核心网的NAS层服务数据流(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中发送给基站。网络设备根据QoS flow的ID信息将其映射至不同的数据无线承载(Data Radio Bearer，DRB)，在空口上发送给终端设备。同理，对于上行数据，类似的操作也被实施。
基于同步信号块(Synchronization Signal Block，SSB)的随机接入资源划分：
在5GNR中，因为波束赋形技术的大规模应用，终端设备在执行随机接入时候希望在特定的波束上接收网络回复的msg2/msg4，以提升信息接收功率。
在Rel-15NR中，网络设备为面向不同方向的SSB分配不同的随机接入资源(如随机接入时频资源或者随机接入前导码)，以便终端设备选择与自己期望相符的SSB的对应的随机接入资源执行随机接入。当网络设备接收到终端设备的msg1后，根据终端设备使用的随机接入前导码和/或随机接入时频资源，判断终端设备期望的发送下行信息的SSB。
结合参考图5中的(a)，ssb-perRACH-OccasionAndCB-PreamblesPerSSB设为1:52，表示1个SSB占用1个RO，1个SSB对应52个基于碰撞的前导码(CB-Preambles)；msg1-FDM设为2，表示同一时间，有两个处在不同频域的RO；属于SSB 0～3的RO资源分别为RO 0～3。
结合参考图5中的(b)，sssb-perRACH-OccasionAndCB-PreamblesPerSSB 设为4:13，表示4个SSB共享1个RO，1个SSB对应13个基于碰撞的随机接入前导码。可以看出SSB0～4都共享每一个RO，但应用不同的前导码集合。
图6示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR-U系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本申请实施例中，上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。网络设备120与终端设备14之间通过某种空口技术互相通信，例如Uu接口。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced Long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本申请实施例也可以应用于这些通信系统。
图7示出了本申请一个示例性实施例提供的随机接入资源的确定方法的流程图。该方法可以应用于如图6示出的终端设备和网络设备中，该方法包括：
步骤710，网络设备向终端设备发送随机接入配置信息，随机接入配置信息 用于指示随机接入资源按照网络切片或与网络切片具有映射关系的对象进行分配。
随机接入配置信息是网络设备对随机接入进行配置的信息，随机接入信息包括将随机接入资源按照网络切片或与网络切片具有映射关系的对象进行分配所得到的分配结果。
其中，随机接入资源包括但不限于：随机接入时频资源和随机接入前导码中的至少一种。
在一种实现方式中，随机接入配置信息可以用于指示将随机接入时频资源按照网络切片或与网络切片具有映射关系的对象进行分配；在另一种实现方式中，随机接入配置信息可以用于指示将随机接入前导码按照网络切片或与网络切片具有映射关系的对象进行分配。
其中，网络切片(NetworkSlice)，是基于协议数据单元会话(PDUsession)的切片网络，需要通过RAN侧和CN侧进行联合处理。每个网络切片从无线接入网承载网再到核心网上进行逻辑隔离，满足不同类型的应用程序的要求。
网络切片和与网络切片具有映射关系的对象之间存在一对一关系，或，多对一关系。也就是说，多个网络切片对应于一个与网络切片具有映射关系的对象，或，一个网络切片对应于一个与网络切片具有映射关系的对象。与网络切片具有映射关系的对象支持通过该对象，查询到对应的一个或多个网络切片。
可选地，与网络切片具有映射关系的对象对应的标识是对网络切片的标识运算后所得到的数据，本申请实施例对具体的运算方式不进行限制。
可选地，网络切片的标识指的是网络切片对应的单一网络切片选择辅助信息(Single-Network Slice Selection Assistance Information，S-NSSAI)。每一个网络切片都由一个唯一的S-NSSAI所标识。S-NSSAI由切片或服务类型(Slice/Service Type，SST)和切片组(Slice Differentiator，SD)组成，SST代表业务类型，SD代表相同的业务类型下服务的不同终端组。
也就是说，网络切片的标识或与网络切片具有映射关系的对象的标识都可以标识网络切片，网络设备对随机接入资源按照网络切片分配后，通过随机接入配置信息告知终端设备随机接入资源与网络切片之间的绑定关系。可选地，网络设备对随机接入资源进行分配时，对于业务较多或者业务性能需求较高的网络切片分配较多的随机接入资源，对于业务较少的或者业务性能需求较低的网络切片分配较少的随机接入资源。
可选地，随机接入配置信息除了指示随机接入资源按照网络切片或与网络切片具有映射关系的对象进行分配之外，还可以指示随机接入资源按照非数据传输业务进行分配。
非数据传输业务是与数据传输无关的业务，非数据传输业务包括但不限于：跟踪区域更新(tracking area update)、上行时间提前量获取和无线接入网络告知区域更新(ran notification area update)。
步骤720，终端设备接收随机接入配置信息。
步骤730，终端设备根据随机接入配置信息，确定随机接入资源。
其中，随机接入资源与终端设备待接入的目标网络切片相匹配。
由于随机接入配置信息中配置了随机接入时频资源按照网络切片或与网络切片具有映射关系的对象进行分配后的分配结果，则终端设备可以根据网络设备的配置，在自己想接入目标网络切片时，选择与目标网络切片对应的随机接入资源。
可选地，在与目标网络切片对应的随机接入资源有多个的情况下，终端设备随机选择其中一个随机接入资源，或，依据一定的规则选择一个随机接入资源。
综上所述，本实施例提供的方法，网络设备通过向终端设备发送随机接入配置信息，指示随机接入资源与网络切片之间的绑定关系，由于网络设备可以根据不同的网络切片对随机接入资源进行灵活分配，如调高对应于关键的网络切片/受欢迎的切片业务的随机接入资源的规模，或，调低对应于普通的网络切片/较冷门的切片业务的随机接入资源的规模，使得终端设备在根据随机接入配置信息确定随机接入资源时，可以根据自己待接入的目标网络切片选择对应的随机接入资源，减少碰撞的概率。
同时，本实施例提供的方法，由于随机接入资源与网络切片之间存在绑定关系，网络设备在随机接入过程中，通过随机接入资源可以知晓终端设备想要接入的目标网络切片，从而可以根据当前的网络负载情况，决定是否需要拒绝终端设备的随机接入，提高通信的效率。
在基于图7的可选实施例中，网络设备将随机接入资源按照网络切片或与网络切片具有映射关系的对象进行分配，可以包括如下两种实现方式：
实现方式1：网络设备将随机接入前导码按照网络切片或与网络切片具有映射关系的对象进行分配。
也就是说，网络设备对前导码域进行切片划分，随机接入前导码与网络切片之间存在绑定关系。
相应地，此时网络设备发送的随机接入配置信息包括第一分配结果，第一分配结果是随机接入前导码按照网络切片或与网络切片具有映射关系的对象进行分配所得到的分配结果。
实现方式2：网络设备将随机接入时频资源按照网络切片或与网络切片具有映射关系的对象进行分配。
也就是说，网络设备对随机接入时频域进行切片划分，RO与网络切片之间存在绑定关系。
相应地，此时网络设备发送的随机接入配置信息包括第二分配结果，第二分配结果是随机接入时频资源按照网络切片或与网络切片具有映射关系的对象进行分配所得到的分配结果。
下面，对上述两种实现方式进行示例性的说明。
实现方式1：
随机接入配置信息包括第一分配结果，第一分配结果是随机接入前导码按照网络切片或与网络切片具有映射关系的对象进行分配所得到的分配结果。
在本申请实施例中，一个随机接入前导码可以唯一的对应于一个网络切片，也可以是其中的一个随机接入前导码对应于两个或两个以上的网络切片。
终端设备根据第一分配结果，在自身需要接入的网络切片是网络切片a时，即可在与网络切片a相匹配的随机接入前导码中，挑选一个目标随机接入前导码，执行随机接入。
可选地，第一分配结果包括如下至少一项：
一、为至少一个网络切片或与至少一个网络切片具有映射关系的对象分配的随机接入前导码的数量的比值。
示例性的，存在网络切片a和网络切片b。为网络切片a和网络切片b分配的随机接入前导码的数量的比值为3:2。
二、为至少一个网络切片或与至少一个网络切片具有映射关系的对象分配的随机接入前导码的数量。
示例性的，存在网络切片a和网络切片b。为网络切片a和网络切片b分配的随机接入前导码的数量分别为：12和40。
三、是否为至少一个网络切片或与至少一个网络切片具有映射关系的对象分配随机接入前导码的位图。
示例性的，存在网络切片a和网络切片b。为网络切片a和网络切片b分配的随机接入前导码的位图为“11”，即为网络切片a和网络切片b均分配随机接入前导码；为网络切片a和网络切片b分配的随机接入前导码的位图为“10”，即为网络切片a分配随机接入前导码，不为网络切片b分配随机接入前导码；为网络切片a和网络切片b分配的随机接入前导码的位图为“00”，即为网络切片a和网络切片b均不分配随机接入前导码。
在一种实现方式中，第一分配结果包括：上述第一项；在另一种实现方式中，第一分配结果包括：上述第二项；在另一种实现方式中，第一分配结果包括：上述第一项和第三项；在另一种实现方式中，第一分配结果包括：上述第二项和第三项。
可选地，随机接入前导码是按照网络切片的标识或与网络切片具有映射关系的对象的标识升序进行分配的；或，随机接入前导码是按照网络切片的标识或与网络切片具有映射关系的对象的标识降序进行分配的。
也就是说，网络设备可以先将随机接入前导码分配给标识数值较小的网络切片或标识数值较小的与网络切片具有映射关系的对象(即升序分配)，也可以先将随机接入前导码分配给标识数值较大的网络切片或标识数值较大的与网络切片具有映射关系的对象(即降序分配)。
示例性的，结合参考图8，其示出了对前导码域进行切片划分的示意图。
msg1-FDM设为2，表示同一时间，有两个处在不同频域的RO；totalNumberOfRA-Preambles为60，表示小区随机接入过程中可以使用的前导码总个数是60；ssb-perRACH-OccasionAndCB-PreamblesPerSSB为2:25，表示2个SSB共享1个RO，1个SSB对应25个基于碰撞的随机接入前导码；numberOfRA-PreamblesGroupA为10，表示属于GroupA的随机接入前导码的数量为10。
网络设备对前导码域进行切片划分，第一分配结果可以包括：slice 0:slice 1＝3:2；第一分配结果也可以包括：分配给slice 0的随机接入前导码个数为36，slice 1的随机接入前导码个数为24；第一分配结果也可以包括：slice 0:slice 1＝3:2,位图(bitmap)＝‘011’(slice 2设为0)；第一分配结果也可以包括：分配给slice 0的随机接入前导码个数为36，slice 1的随机接入前导码个数为24，bitmap＝‘011’。
如图8所示，RO 1对应于SSB1和SSB2，分配给slice 0的随机接入前导码个数共有36个，分配给slice 1的随机接入前导码个数共有24个。
结合参考图9，若终端设备想接入的目标网络切片是slice 0，则终端设备可以选择随机接入前导码18，尝试接入网络。若终端设备想接入的目标网络切片是slice 1，则终端设备可以选择随机接入前导码30，尝试接入网络。
实现方式2：
随机接入配置信息包括第二分配结果，第二分配结果是随机接入时频资源按照网络切片或与网络切片具有映射关系的对象进行分配所得到的分配结果。
在本申请实施例中，一个随机接入时频资源可以唯一的对应于一个网络切片，也可以是其中的一个随机接入时频资源对应于两个或两个以上的网络切片。
终端设备根据第二分配结果，在自身需要接入的网络切片是网络切片a时，即可在与网络切片a相匹配的随机接入时频资源中，挑选一个随机接入时频资源，执行随机接入。
可选地，第二分配结果包括如下至少一项：
一、为至少一个网络切片或与至少一个网络切片具有映射关系的对象分配的随机接入时频资源的数量的比值。
示例性的，存在网络切片a和网络切片b。为网络切片a和网络切片b分配的随机接入时频资源的数量的比值为3:1。
二、为至少一个网络切片或与至少一个网络切片具有映射关系的对象分配的随机接入时频资源的数量。
示例性的，存在网络切片a和网络切片b。为网络切片a和网络切片b分配的随机接入时频资源的数量分别为：3和1。
三、是否为至少一个网络切片或与至少一个网络切片具有映射关系的对象分配随机接入时频资源的位图。
示例性的，存在网络切片a、网络切片b和网络切片c。为网络切片a、网络切片b和网络切片c分配的随机接入时频资源的位图为“011”，即为网络切片a和网络切片b均分配随机接入时频资源，不为网络切片c分配随机接入时频资源。
在一种实现方式中，第二分配结果包括：上述第一项；在另一种实现方式中，第二分配结果包括：上述第二项；在另一种实现方式中，第二分配结果包括：上述第一项和第三项；在另一种实现方式中，第二分配结果包括：上述第二项和第三项。
可选地，随机接入时频资源是按照网络切片的标识或与网络切片具有映射 关系的对象的标识升序进行分配的；或，随机接入时频资源是按照网络切片的标识或与网络切片具有映射关系的对象的标识降序进行分配的。
也就是说，网络设备可以先将随机接入时频资源分配给标识数值较小的网络切片或标识数值较小的与网络切片具有映射关系的对象(即升序分配)，也可以先将随机接入时频资源分配给标识数值较大的网络切片或标识数值较大的与网络切片具有映射关系的对象(即降序分配)。
示例性的，结合参考图10，其示出了对随机接入时频域进行切片划分的示意图。
msg1-FDM设为4，表示同一时间，有四个处在不同频域的RO；totalNumberOfRA-Preambles为60，表示小区随机接入过程中可以使用的前导码总个数是60；ssb-perRACH-OccasionAndCB-PreamblesPerSSB为4:15，表示4个SSB共享1个RO，1个SSB对应15个基于碰撞的随机接入前导码。
网络设备对前导码域进行切片划分，第二分配结果可以包括：slice 0:slice 1＝3:1；第二分配结果也可以包括：分配给slice 0的RO个数为3，slice 1的RO个数为1；第二分配结果也可以包括：slice 0:slice 1＝3:1，bitmap＝‘011’(slice 2设为0)；第二分配结果也可以包括：分配给slice 0的RO个数为3，slice 1的RO个数为1，bitmap＝‘011’。
如图10所示，RO 0、RO 1和RO 2分配给slice 0，RO 3分配给slice 1。
结合参考图11，若终端设备想接入的目标网络切片是slice 0，则终端设备可以选择RO 0，尝试接入网络。若终端设备想接入的目标网络切片是slice 1，则终端设备可以选择RO 3，尝试接入网络。
综上所述，网络设备发送的随机接入配置信息可以包括第一分配结果，即将随机接入前导码按照网络切片或与网络切片具有映射关系的对象进行分配，也可以包括第二分配结果，即将随机接入时频资源按照网络切片或与网络切片具有映射关系的对象进行分配，提高了随机接入资源的确定方法的灵活性。
在基于图7的可选实施例中，图12示出了本申请一个示例性实施例提供的随机接入资源的确定方法的流程图。在本实施例中，还包括步骤740和步骤750：
步骤740，网络设备确定随机接入配置信息。
其中，随机接入配置信息是网络设备根据网络负载情况、网络能力和终端历史接入信息中的至少一种确定的。
步骤710，网络设备向终端设备发送随机接入配置信息，随机接入配置信息用于指示随机接入资源按照网络切片或与网络切片具有映射关系的对象进行分配。
可选地，随机接入配置信息携带在系统消息中；或，随机接入配置信息携带在RRC信令中。网络设备也可以通过其他的信令发送随机接入配置信息，本申请实施例对此不进行限制。
可选地，随机接入资源还可以按照非数据传输业务进行分配。非数据传输业务包括：追踪区域更新、上行时间提前量获取和无线接入网络告知区域更新中的至少一种。
在一种实现方式中，网络切片包括默认网络切片，默认网络切片用于承载基本传输性能要求的业务和/或与非数据传输业务相关联。如：默认网络切片只与非数据传输业务相关联；或，默认网络切片只用于承载eMBB业务(即基本传输性能要求的业务)；或，默认网络切片既用于承载eMBB业务，也用于与非数据传输业务相关联。也就是说，由于默认网络切片可以承载非数据传输业务，则随机接入资源可以按照非数据传输业务进行分配。
在另一种实现方式中，随机接入配置信息还用于指示随机接入资源与因非数据传输业务而执行的随机接入之间的对应关系。也就是说，非数据传输业务不由网络切片(如默认网络切片)进行承载，随机接入配置信息额外的对随机接入资源与因非数据传输业务而执行的随机接入之间的对应关系进行指示。
步骤720，终端设备接收随机接入配置信息。
步骤730，终端设备根据随机接入配置信息，确定随机接入资源。
步骤750，终端设备使用随机接入资源执行随机接入。
可选地，随机接入资源包括：随机接入前导码和随机接入时频资源中的至少一种。终端设备通过随机接入时频资源，向网络设备发送随机接入前导码。
