图2是根据本申请一实施例随机接入信息的处理方法200的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S210、终端发送随机接入报告，该随机接入报告中包括该终端与执行的随机接入相关的业务的切片信息。
在一种示例中，终端在有上行数据发送、接收下行数据和进行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：基于碰撞的和免于碰撞的。
如图3所示，在基于碰撞的随机接入过程中，终端在一个随机接入时频资源上(RACH occasion)上使用一个公共的随机接入前导码(RACH preamble)发送消息1(msg1)。之后，终端用RA(Random Access，随机接入)-RNTI(Radio Network Temporary Identifier,网络临时标识符)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。当发现关于RAR的PDCCH指示信息后，终端会在PDCCH指示信息给出的时频位置上解码RAR。如果RAR中包括终端发送的随机接入前导码信息，终端继而会应用RAR中与该随机接入前导码对应的信息进而发送消息3(msg3)。例如，图3中的subPDU表示子PDU(Protocol Data Unit，协议数据单元)，Padding(opt)表示填充是可选项。终端发现在MAC subPDU3这种格式中包括与自身preamble ID相符的一个子头，后续可以使用相关的MAC RAR中的内容发送msg3。
如图4所示，为RAR包括的具体内容的示例。RAR中可以包括Timing Advance Command(定时提前命令)、UL Grant(上行授权)、Temporary(临时)C-RNTI等。
在包含有无线资源控制(Radio Resource Control，RRC)连接建立请求(RRCSetupRequest)等RRC命令的msg3中，终端需要携带有自身UE ID(identification，标识)。在具有众多终端做随机接入的情况下，可能会有其他 终端在上行授权(uplink grant，UL grant)指示的时频位置上也发送msg3(携带该终端UE ID)尝试接入网络。该情况下，终端之间会发生随机接入碰撞，网络在消息4(msg4)中可以只会携带有其中一个UE的ID允许其接入网络。
如图5所示，为随机接入过程的一种示例：终端1和终端2向网络设备例如gNB发送消息1(msg1)，其中可以包括前导码(preamble)。gNB向终端1和终端2返回消息2(msg2)，其中包括随机接入响应RAR，RAR中包括上行授权(UL grant)。终端1和终端2向网络设备发送消息3(msg3)，例如RRC连接建立请求(RRCSetupRequest)，其中可以包括终端标识，例如UE ID#1和UE ID#2。gNB返回RRC连接建立结果，其中可以包括成功建立拦截的终端标识，例如UE ID#1。这时，gNB可以向终端1返回RRC连接建立成功的消息，向终端2返回RRC连接建立失败的消息。
网络切片可以包括RAN(Radio Access Network，无线接入网)部分和CN(Core Network，核心网)部分。通信网络对网络切片的支持依赖于将隶属于不同切片的的数据通信由不同的PDU会话(session)承载。不同的切片具有不同的网络切片选择协助信息(Network Slice Selection Assistance Information，NSSAI)，以及不同的传输性能要求如可靠性、传输时延、传输速率等。在实际应用中，网络可以将eMBB(enhanced Mobile Broadband，增强移动宽带)和URLLC(Ultra-low latency communication，超高可靠性与超低时延)的业务在不同的PDU会话上进行承载。每个不同的PDU会话可以具有多个Qos(Quality of Service，服务质量)流(flow)。
例如，如图6所示，在具体通信中，在下行方向，核心网的NAS层SDF(业务数据流，Service data flow)模板(template)将来自应用层的不同的数据包进行分类，映射至不同PDU会话(session)中的不同QoS流(QoS flow)，并且使QoS流在不同的PDU会话中发送给基站。其中，SDF模板可以在UPF(User Plane Function，用户面功能)中。基站根据QoS流的ID信息将QoS流映射至不同的DRB(Data Radio Bearer，数据无线承载)在空口上发送给终端。同理，对于上行数据，类似的操作也被实施。图6中的AN(Access Network，接入网)资源可以包括无线承载DRB。QoS规则(rules)可以包括：将应用层的数据包例如UL数据包根据QoS要求的不同要求，映射到不同的QoS流，并应用不同的QoS流标记。同一QoS流中的所有数据包标记相同的QoS流ID。
在一种示例中，可以基于SSB划分随机接入资源。在5G NR中，因为波束赋形技术的大规模应用，终端在执行随机接入时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，网络为面向不同方向的SSB分配不同的随机接入资源(如RO或者随机接入前导码)，以便终端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。当网络接收到终端的msg1后，根据终端使用的随机接入前导码和/或随机接入时频资源(RACH ocassion)判断终端期望的发送下行信息的SSB。
参见图7，在一种示例中，如果面向SSB的随机接入机会(例如，ssb-perRACH-OccasionAndCB-PreamblesPerSSB)设为1:52，Msg1-FDM设为2，则属于SSB 0～SSB 3的RO资源分别为RO 0～RO3。其中，SSB 0～SSB3应用的前导码集合相同，例如preamble 0～51。此外，在本示例中，SSB0和SSB1对应的SFN(System Frame Number，系统帧号)为5，子帧Subframe为9；SSB2和SSB3对应的SFN为9，子帧Subframe为9。
参见图8，在一种示例中，如果面向SSB的随机接入机会(例如，ssb-perRACH-OccasionAndCB-PreamblesPerSSB)设为4:13，Msg1-FDM设为1，SSB0～SSB 4共享每一个RO，但应用不同的前导码集合。例如，SSB0的前导码集合为preamble 0～12；SSB1的前导码集合为preamble 16～28；SSB2的前导码集合为preamble 32～44；SSB3的前导码集合为preamble 48～60。此外，在本示例中，SSB0～SSB3对应的SFN为5，子帧Subframe为9。
为了在随机接入阶段使得面向不同切片业务发起随机接入的终端不互相发生随机接入冲突，可以按照不同切片划分随机接入资源，实现随机接入优化。
网络在配置随机接入资源和相关参数的时候可能存在不合理，影响终端随机接入体验的情况下。网络需要终端上报以修正配置错误。本实施例中，可以优化终端需要上报的内容。
如图9所示，为上报流程的示例。在随机接入过程之后，网络设备例如gNB可以向终端例如UE发送信息请求(Information Request)，其中的随机接入报告请求设置为真(ra-ReportReq is set as true)。终端可以向网络设备返回信息响应(Information Response)，其中可以包括随机接入报告，例如ra-ReportList-r16。
上报内容可以包括在面向某SSB做随机接入中尝试过的随机接入前导码 的发送次数(NumberOfPreamblesSentOnSSB)、相应的每次尝试过程中是否遇到碰撞的指示。在本申请实施例中，可以在随机接入报告中加入终端与执行的随机接入相关的业务的切片信息。这样，网络设备可以根据随机接入前导码的发送次数、碰撞的指示、切片信息等，确定是否调整该切片信息对应的随机接入资源。例如调整随机接入时机数目和/或随机接入前导码数目等。
可选地，在本申请实施例中，该切片信息包括用于标识一个网络切片的标识或者与网络切片有对应关系的对象的标识。
示例性地，用于标识一个网络切片的标识可以为标识一个网络切片的S-NSSAI(Single Network Slice Selection Assistance Information，单一网络切片选择协助信息)。
示例性地，如果小区为每个网络切片ID从小到大排序后赋予ID从1,2,3,4……的索引号，终端在上报时可以不上报网络切片的值，而上报ID的索引值。
可选地，在本申请实施例中，该切片信息包括该终端所接入的小区支持的切片标识集合中一个切片标识的索引值。
示例性地，终端所接入的小区支持的切片标识集合可以为NSSAI集合。切片标识集合中一个切片标识的索引值可以为NSSAI集合中某个S-NSSAI的索引值。
可选地，在本申请实施例中，该随机接入报告中还包括在与至少一个同步信号块(SSB)或至少一个信道状态信息参考信号(Channel-state information Reference Signal，CSI-RS)相关的随机接入过程中尝试过的前导码的发送次数和/或前导码碰撞信息。
示例性地，如果执行随机接入过程中尝试过的前导码的发送次数过多，例如超过某个阈值，可以判定为该终端执行随机接入的切片分配的随机接入资源过少，可以增加该切片对应的随机接入资源。
本申请实施例中，在终端的随机接入报告中包括终端与执行的随机接入相关的业务的切片信息，可以辅助网络按照切片信息分配随机接入资源，优化随机接入资源的分配方式。
图10是根据本申请一实施例随机接入信息的处理方法300的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S310、网络设备接收随机接入报告，该随机接入报告中包括终端与执行的随机接入相关的业务的切片信息；
S320、该网络设备根据该随机接入报告，确定是否调整该切片信息对应的随机接入资源。
在本实施例中，网络设备收到一个或多个终端发送的随机接入报告后，可以根据其中的内容相应的调整随机接入资源在不同切片上的分配比例。
例如，如图11和图12所示，切片1在每个SSB下的前导码数目为10，切片2在每个SSB下的前导码数目为40。如果有多个终端报告曾经在小区1上面向切片1执行随机接入，在尝试发送10+次随机接入前导码后才最终接入网络，那么提供小区1服务的基站可知晓为该切片1分配的随机接入资源数目不够用，继而对随机接入资源数目进行优化。例如，多个终端上报的随机接入报告内容包含:面向SSB1发送10次前导码、业务切片ID为1以及前9次前导码发送碰撞值设为真。并且，还有多个终端上报的随机接入报告内容包含:面向SSB1发送2次前导码、业务切片ID为2以及前1次前导码发送碰撞值设为真。网络设备可以增加切片1的RO数目或前导码数目，减少切片2的RO数目或前导码数目。例如，优化后切片1在每个SSB下的前导码数目为25，切片2在每个SSB下的前导码数目为25。
可选地，在本申请实施例中，该切片信息包括用于标识一个网络切片的标识或者与网络切片有对应关系的对象的标识。
示例性地，用于标识一个网络切片的标识可以为标识一个网络切片的S-NSSAI。
可选地，在本申请实施例中，该切片信息包括该终端所接入的小区支持的切片标识集合中一个切片标识的索引值。
示例性地，终端所接入的小区支持的切片标识集合可以为NSSAI集合。切片标识集合中一个切片标识的索引值可以为NSSAI集合中某个S-NSSAI的索引值。
可选地，在本申请实施例中，该随机接入报告中还包括在与至少一个SSB或至少一个CSI-RS相关的随机接入过程中尝试过的前导码的发送次数和/或前导码碰撞信息。
示例性地，如果执行随机接入过程中尝试过的前导码的发送次数过多，例如超过某个阈值，网络设备可以判定为该终端执行随机接入的切片分配的 随机接入资源过少，可以增加该切片对应的随机接入资源。
可选地，在本申请实施例中，该网络设备根据该随机接入报告，确定是否调整该切片信息对应的随机接入资源，包括：
该网络设备根据发送前导码的次数和/或前导码碰撞信息，确定是否调整该切片信息对应的前导码数目和/或RO数目。
本实施例的网络设备执行方法300的具体示例可以参见上述方法200的中关于网络设备例如基站的相关描述，为了简洁，在此不再赘述。
在本申请实施例中，随机接入信息的处理方法是一种基于终端反馈进行随机接入优化的方法，可以帮助网络优化为不同切片分配的随机接入资源大小，以提高不同切片终端的总体随机接入体验，以及目标为关键切片的终端的随机接入体验。随机接入体验的高低主要与接入碰撞概率低或者高有关。一般来说，碰撞的越多，需要重新发送前导码的次数也越多，随机接入的时延也越大。
