具体实施方式
5G在网络速度、网络延迟和连接规模等关键性能上相比2/3/4G有了重大飞跃，使其能够适应多种多样的场景和差异化服务需求。与此同时5G网络需要支持更加灵活的空口技术和网络架构，5G网络的灵活性也不可避免地带来了网络的复杂性。网络复杂性的增长使得传统网络运维模式难以为继。
伴随着中央处理器(central processing unit，CPU)/图形处理器(graphics processing unit，GPU)等硬件计算能力不断增强，人工智能(artificial intelligence，AI)技术快速兴起并成功应用于语音识别、人脸识别、无线通信领域运维简化、算法优化等多个领域。目前，许多运营商正在大规模试验和部署机器学习和其他AI技术，探索如何利用人工智能工具实现更高效的无线资源管理和更加自动化的网络运营维护，以减少运营费用(operating expense，OPEX)并快速、敏捷的响应新业务需求。
目前，AI技术在无线网络中广泛开展研究已驱动产业进行系统性的网络重构，如建立AI应用市场平台，支持优化算法模型的分发和独立部署。例如，一种面向ML模型的无线智能网络架构可以如图1所示，该架构为支持ML模型包/文件的可动态加载/更新的交换框架，基于ML模型自动加载架构包括ML模型设计模块、ML模型训练模块、ML模型管理模块。ML模型设计模块用于设计ML模型。ML模型训练模块用于基于来自无线设备的训练数据对ML模型设计模块设计的ML模型进行训练。ML模型管理模块用于将ML模型训练模块训练好的ML模型发送给无线设备。该架构可以支持联邦学习机制等，从传递数据转为传递ML模型，从而解决AI训练数据量大等问题，提升ML模型再训练精度。其中，ML模型自动加载架构支持将ML模型加载到无线设备。
终端设备和无线网络之间需要进行物理层，媒体接入控制，无线资源控制，无线资源管理，运维等领域的智能计算，因此终端设备和接入网设备之间存在计算数据，如用于智能计算的计算模型相关数据等，计算模型可以为ML模型等等。计算数据可以是由接入网设备、核心网设备或者运维服务器等处理得到的，然后由接入网设备发送给终端设备。目前，网络侧向终端侧发送数据的方式主要有通过SRB或DRB传输。
由于SRB仅支持传输简单的小尺寸报文控制信令，而计算数据通常数据量较大，通常是百万(million，M)量级字节的。并且SRB具有最高优先级，用来传输最高QoS等级的数据或者信令，而计算数据根据任务的不同，具有不同的QoS等级，因此计算数据不适合通过SRB传输。
若将计算数据视为应用层数据通过DRB发送给终端设备，传输过程为，接入网设备处理得到计算数据后，通过用户面功能(user plane function，UPF)实体将计算数据打包成应用程序数据，然后UPF实体将打包得到的应用程序数据向接入网设备进行发送，由接入网设备通过DRB发送给终端设备，如图2所示。通过应用层传输计算数据有以下几个问题：
1、由于接入网设备、核心网设备、或者运维服务器等，属于是无线通信网络内部设备，若作为生成计算数据的服务器，地址需要对公网终端设备可见，这样增加了不必要的网络协议(internet protocol，IP)网络配置，同时让无线网络暴露在公网上，需要增加额外的安全加固措施，从而增加了成本；
2、若通过应用层进行传输，计算数据需要经过的传输路径为：生成计算数据的服务器(如接入网设备、核心网设备、或者运维服务器)->核心网设备->接入网设备->终端设备，传输路径较长，对终端设备的计费也有影响。
3、计算数据在传输时需要的QoS等级、完整性保护等，与应用层用户数据有差异，因此通过应用层传输计算数据，会牺牲了扩展性。
计算数据如何高效从无线网络侧发送到终端，当前缺乏有效的流程。
基于此，本申请实施例提供一种计算数据传输方法及装置，可以实现计算数据的传输。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例提供的计算数据传输方法，该方法可以适用于5G(第五代移动通信系统)系统，如采用新型无线接入技术(new radio access technology，New RAT)的接入网；云无线接入网(cloud radio access network，CRAN)等通信系统。其中，5G系统可以为非漫游场景，也可以为漫游场景。5G系统可以用于服务化的架构，也可以用于基于接口的架构，这里不做具体限定。应理解，本申请实施例也可以适用于在未来通信(例如6G或者其他的网络中)等。
示例的，本申请实施例的通信系统架构可以如图3所示，该通信系统可以包括核心网设备、第一接入网设备、第二接入网设备和终端设备。其中，第一接入网设备或者第二接入网设备能够与核心网设备进行通信；终端设备能够与第一接入网设备或者第二接入网设备进行通信，终端设备也能够与第一接入网设备和第二接入网设备同时进行通信，即多无线双连接(multi radio dual connectivity，MR-DC)。在MR-DC场景下，第一接入网设备可为主接入网设备，第二接入网设备可为辅接入网设备，第一接入网设备和第二接入网设备可为不同通信制式的接入网设备，也可为相同通信制式的接入网设备。应理解，图3仅是一种示例性说明，并不对通信系统中核心网设备、接入网设备、终端设备的数量以及连接关系进行具体限定。

本申请实施例中的终端设备可以实现计算数据收集、计算模型训练、计算模型生成、计算模型更新、计算模型分发等功能，为了描述上的方便，下面将计算数据收集、计算模型训练、计算模型生成、计算模型更新、计算模型分发等功能称为数据分析管理(data analysis and management，DAM)功能。应理解，这里仅是一种示例性命名，并不进行具体限定。
一种实现方式中，终端设备可以包括DAM模块，该DAM模块用于实现该DAM功能，例如数据收集、模型训练、模型生成、动作(action)生成等功能。其模型训练结果用于终端设备或者接入网设备的接入层(如物理层(physical layer，PHY)、媒体介入控制(media access control，MAC)、RLC、RRC等)功能模块，或者其模型训练结果用于终端设备或者核心网设备的非接入层功能模块。
示例性的，终端设备的协议栈可以如图4所示，其中，图4仅示出了终端设备中应用于传输计算数据的协议层。
终端设备可以包括用于实现终端设备与接入网设备之间计算数据的收集、分发等功能的协议层，为了描述上的方便，下面将其称为数据分析协议(data analysis protocol，DAP)层。该DAP层可以支持终端设备与接入网设备之间的计算数据的收集、分发等功能。应理解，DAP仅是一种示例性命名，并不进行具体限定。
终端设备的协议栈还可以包括用于实现终端设备与核心网之间计算数据的收集、分发等功能的协议层，为了描述上的方便，下面将其称为高层数据分析协议(high data analysis protocol，HDAP)层。该HDAP层可以支持终端设备与核心网设备之间的计算数据的收集、分发等功能。应理解，HDAP仅是一种示例性命名，并不进行具体限定。
终端设备还可以包括PDCP层，该PDCP的功能可以包括数据传输(包括计算数据等)、有序发送、加密和解密(包括计算数据的加解密等)、重复检测、基于计时器的丢弃、网络协议(internet protocol，IP)报头压缩和解压等。PDCP可以建立用于传输计算数据的无线承载，为了描述上的方便，下面将用于传输计算数据的无线承载称为计算无线承载(computing radio bearer，CRB)，应理解，这里仅是一种示例性命名，并不对该无线承载 的命名进行具体限定，其中，CRB传输的包大小、QoS等级等可以适用计算数据。
示例性的，CRB可以与SRB/DRB采用不同的逻辑信道标识(logical channel identify，LCID)，例如，CRB可以采用3GPP标准中下行共享信道(downlink-shared channel，DL-SCH)/上行下行共享信道(uplink-shared channel，UL-SCH)中的保留(reserved)的LCID值。一种示例中，CRB可以使用3GPP TS 38.321规范v15.7.0协议中Table 6.2.1-1 Values of LCID for DL-SCH的35～46作为承载从接入网设备传输到终端设备的计算数据的CRB的LCID。另一个示例中，CRB可以使用3GPP TS 38.321规范v15.7.0协议中Table 6.2.1-2 Values of LCID for UL-SCH的35～44作为承载从终端设备传输到接入网设备的计算数据的CRB的LCID。
CRB的QoS特性也可以与SRB/DRB不同，例如，CRB的QoS等级可以低于SRB/DRB。又例如，SRB没有包时延预算(packet delay budget，PDB)，CRB可以有PDB，等等。
CRB与SRB/DRB传输的信息不同，例如，SRB承载的信息为信令，DRB承载的是来自于UE和数据网络的用户应用层数据，CRB承载的无线网络内的计算数据，例如无线网络内的计算模型等。又例如，SRB承载的信息的数据量较小，而CRB可以没有数据量的限制。再例如，SRB传输信息时涉及终端设备的计费，而CRB传输信息时可以不涉及终端设备的计费。
此外，若CRB传输的数据为RAN计算数据，CRB的数据传输可以是接入网设备终止的，即CRB传输的RAN计算数据可以不回传到核心网设备，相比于通过DRB传输计算数据，通过CRB传输计算数据时传输路径较短，从而可以降低传输时延。并且，通过CRB传输RAN计算数据时对终端设备的计费没有影响。若CRB传输的数据为CN计算数据，CRB的数据传输可以是3GPP核心网设备终止的，即CRB传输的CN计算数据可以不传输到3GPP网络之外的数据网络。
示例性的，PDCP层可以包括用于实现计算数据的数据传输、计算数据的加解密等功能的子层。为了描述上的方便，可以将PDCP层支持计算数据的数据传输、计算数据的加解密等功能的子层称为“PDCP-CRB”子层。应理解，PDCP-CRB仅是一种示例性命名，并不进行具体限定。

下面结合附图对本申请实施例提供的计算数据传输方法进行具体说明。
参见图14，为本申请提供的一种计算数据传输方法的流程图。该方法包括：
S1401，终端设备向接入网设备发送第一消息，第一消息用于请求接入网设备建立第一无线承载，第一无线承载用于承载计算数据。相应的，接入网设备接收终端设备发送的第一消息。
随着人工智能、VR/AR等业务的发展，在无线通信网络中衍生出的新的计算要求，例如AI计算(包括AI模型训练和推理所要求的计算)、端边云协同的VR业务实时渲染计算等。围绕这些新的计算，涉及计算任务拆分、计算资源管理和调度协同、AI模型分发等业务流。在此过程中，会产生如用于协商相关计算的交互消息、计算任务拆分数据、描述 计算模型(如AI模型)的数据、计算模型产生的数据等数据。
计算数据可以为随着人工智能、虚拟现实(virtual reality，VR)/移动应用增强现实(augmented reality，AR)等业务的发展无线通信网络中衍生出的数据，例如计算相关协商交互消息、计算任务拆分数据、描述计算模型(如AI模型)的数据、计算模型产生的数据等。
示例性的，传输计算数据的通道可以称为智能计算平面、计算面、计算层面、计算平面等。应理解，计算数据也可以称为智能计算数据、计算平面数据、计算面数据等。
为了描述上的方便，下面将用于承载计算数据的第一无线承载称为CRB。
S1402，接入网设备向终端设备发送第二消息，第二消息携带CRB配置信息。相应的，终端设备接收接入网设备发送的第二消息。
一种示例性说明中，CRB配置信息可以包括CRB的PDCP-CRB子层配置(例如排序递交定时器等)、CRB的RLC模式(确认、非确认、透明)、CRB的上下行RLC层配置(例如序列号字段长度、重传定时器等)、CRB的逻辑信道标识及优先级配置等。
S1403，终端设备基于CRB配置信息建立与接入网设备之间的CRB。
CRB用于终端设备与接入网设备之间传输接入网计算数据或核心网计算数据。
本申请实施例中，终端设备和接入网设备支持建立用于传输计算数据的无线承载，终端设备和接入网设备可以通过该无线承载实现计算模型等计算数据的传输，通过CRB传输计算数据，使得计算数据的传输可以不用受SRB传输、DRB传输的限制。
在终端设备与接入网设备之间建立起CRB后，终端设备和接入网设备可以通过建立的CRB传输计算数据。其中，计算数据的传输可以从接入网设备传输到终端设备，也可以从终端设备传输到接入网设备。
对于从接入网设备传输到终端设备的第一计算数据的传输，接入网设备可以通过建立的CRB向终端设备发送第一计算数据。其中，第一计算数据可以是接入网计算数据，也可以是核心网计算数据。
若第一计算数据是RAN计算数据，第一计算数据可以是接入网设备的DAP实体输出的数据。终端设备在接收到第一计算数据后可以传输到终端设备的DAP实体进行处理，例如，如图15a所示。
在一种实现方式中，若RAN-DAM模块与接入网设备独立部署，接入网设备可以接收RAN-DAM发送的RAN计算数据，并将该RAN计算数据通过CRB发送给终端设备。
在另一种实现方式中，若RAN-DAM模块与接入网设备集成部署，接入网设备的RAN-DAM可以通过接入网设备的内部接口向接入网设备的控制面或用户面功能发送RAN计算数据，接入网设备的控制面或用户面功能将该RAN计算数据通过CRB发送给终端设备，例如，如图15b所示。
若第一计算数据是CN计算数据，第一计算数据可以是核心网设备的HDAP实体输出的数据。核心网设备可以将第一计算数据通过NG接口发送给接入网设备，再由接入网设备通过建立的CRB发送给终端设备。终端设备在接收到第一计算数据后传输到终端设备的HDAP实体进行处理。
在一种可能的实施方式中，接入网设备可以根据CRB最大传输数据量将第一计算数据进行分段，得到多个子数据段。接入网设备可以将该多个子数据段依次通过CRB发送给终端设备。
其中，子数据段的大小可以不大于预设阈值，或者，子数据段的大小可以小于预设阈值，其中，预设阈值可以为CRB最大传输数据量。例如，假设预设阈值为9000字节，则子数据的大小可以不大于9000字节。
一种举例说明中，接入网设备可以通过如下方式将该多个子数据段发送给终端设备：
A1，接入网设备向终端设备依次发送多个消息，每个消息携带序列号、确认请求以及一个子数据段的数据。其中，序列号用于标识该子数据段。确认请求用于指示终端设备在接收到数据后是否发送确认消息，例如，若确认请求为假(false)，可以指示终端设备在接收到数据后不发送确认消息，若确认请求为真(true)，可以指示终端设备在接收到数据后发送确认消息。
A2，终端设备在正确接收到消息后，若该消息携带的确认请求为false，则终端设备不发送确认消息。若该消息携带的确认请求为true，则终端设备发送确认消息。
其中，该确认消息可以是针对本次接收到的消息发送的，或者，该确认消息也可以是针对本次消息以及本次消息之前的一个或多个消息确认的，例如，该确认消息可以携带列表，该列表可以包括本次消息以及本次消息之前的一个或多个消息中成功接收的子数据段的序列号。
A3，接入网设备根据接收到确认消息重传终端设备未成功接收的一个或多个子数据段的数据。
例如，如图16所示，接入网设备向终端设备依次发送DAP消息1～DAP消息N+1，其中，DAP消息1携带子数据段1的序列号、确认请求(false)以及子数据段1的数据，DAP消息N携带子数据段N的序列号、确认请求(true)以及子数据段N的数据，DAP消息N+1携带子数据段N+1的序列号、确认请求(false)以及子数据段N+1的数据。终端设备在接收到DAP消息N之后向接入网设备发送DAP确认指示，该DAP确认指示可以携带终端设备成功接收到的子数据段的序列号。接入网设备根据该DAP确认指示重传子数据段1～N中终端设备未成功接收的子数据段。
可以理解的，DAP消息可以通过一个字段来指示确认请求，例如，该字段为true时可以指示终端设备在接收到数据后发送确认消息，若该字段为false时可以指示终端设备在接收到数据后不发送确认消息。或者，DAP消息也可以通过1比特来指示确认请求，例如，该比特取值为1时可以指示终端设备在接收到数据后发送确认消息，若该比特取值为0时可以指示终端设备在接收到数据后不发送确认消息。
另一种举例说明中，接入网设备也可以通过如下方式将该多个子数据段发送给终端设备：
B1，接入网设备向终端设备依次发送多个消息，每个消息携带后续包指示以及一个子数据段的数据，该后续包指示用于指示是否有下一个子数据段要接收。例如，若后续包指示为是(Yes)，可以指示终端设备接收下一个子数据段的数据，或者，也可以指示数据传输未结束。若后续包指示为否(No)，可以指示没有下一个子数据段的数据，或者也可以指示数据传输结束。
B2，终端设备在接收到消息后，若该消息携带的后续包指示为Yes，则终端设备继续接收下个消息。若该消息携带的后续包指示为No，则终端设备可以确认数据传输结束。
例如，如图17所示，第一计算数据包括N个子数据段，接入网设备向终端设备依次发送DAP消息1～DAP消息N，其中，DAP消息1～DAP消息N-1分别携带一个子数据段 的数据以及后续包指示，且DAP消息1～DAP消息N-1携带的后续包指示为Yes。DAP消息N携带子数据N以及后续包指示，且DAP消息N携带的后续包指示为No。终端设备接收接入网设备发送的DAP消息，直到接收到后续包指示为No的DAP消息N。
可以理解的，DAP消息可以通过一个字段来指示是否有后续包，例如，该字段为Yes时可以指示有后续包，若该字段为No时可以指示没有后续包。或者，DAP消息也可以通过1比特来指示是否有后续包，例如，该比特取值为1时可以指示有后续包，若该比特取值为0时可以指示没有后续包。
由于CRB支持发送的数据包大小可能有限，通过上述两种方式可以将较大的计算数据进行分段发送，并且可以降低丢包的概率。
对于从终端设备传输到接入网设备的第二计算数据的传输，终端设备可以通过建立的CRB向接入网设备发送第二计算数据。其中，第二计算数据可以是RAN计算数据，也可以是CN计算数据。
若第二计算数据是RAN计算数据，第二计算数据可以是终端设备的DAP实体输出的数据。接入网设备在接收到第二计算数据后，可以传输到接入网设备的DAP层进行处理。这种场景下，CRB的数据传输可以是接入网设备终止的，即CRB传输的RAN计算数据可以不回传到核心网设备。
若第二计算数据是CN计算数据，第二计算数据可以是终端设备的HDAP实体输出的数据。接入网设备在接收到第二计算数据后，可以发送给核心网设备，由核心网设备的HDAP实体进行处理。这种场景下，CRB的数据传输可以是3GPP核心网设备终止的，即CRB传输的CN计算数据可以不传输到公网。
在一种实现方式中，若RAN-DAM模块与接入网设备独立部署，接入网设备在接收到终端设备发送的RAN计算数据之后，还可以向RAN-DAM发送该RAN计算数据。RAN-DAM在接收到RAN计算数据后可以对RAN计算数据进行处理，例如，以计算数据为AI模型为例，RAN-DAM在接收到计算数据后可以将计算模型进行融合，如图18a所示。
在另一种实现方式中，若RAN-DAM模块与接入网设备集成部署，终端设备向接入网设备发送RAN计算数据时，可以是接入网设备的控制面或用户面功能接收RAN计算数据，并通过接入网设备的内部接口向RAN-DAM实体发送该RAN计算数据，如图18b所示。RAN-DAM实体在接收到RAN计算数据后可以对RAN计算数据进行处理，例如，以RAN计算数据为AI模型为例，RAN-DAM实体在接收到RAN计算数据后可以将计算模型进行融合。
示例性的，终端设备向接入网设备发送第二计算数据的方法，与接入网设备向终端设备发送第一计算数据的方法类似，具体可以参阅上述接入网设备向终端设备发送第一计算数据的相关描述，这里不再重复赘述。
需要说明的是，在一种实现中，在上述终端设备与接入网设备之间建立CRB之前，网络侧还需要获取终端设备是否支持CRB。例如，在步骤S1402之前，终端设备可以向接入网设备上报能力信息，该能力信息用于指示终端设备支持CRB。其中，该能力信息可以是终端设备可以主动上报的。或者，该能力信息也可以是终端设备在接入网设备发送的第七消息的触发下上报的，第七消息用于查询终端设备是否支持CRB。
为了更好的理解上述终端设备上报能力信息的方法，下面结合具体场景对终端设备上 报能力信息的过程进行举例说明。如图19所示，终端设备上报能力信息的过程包括：
S1901，终端设备向接入网设备发送RRC建立请求(RRCSetupRequest)消息。
S1902，接入网设备向终端设备发送RRC建立(RRCSetup)消息。
可选的，RRCSetup消息可以包含建立SRB1承载信息和无线资源配置信息。
S1903，终端设备建立SRB1承载，并配置无线资源。
S1904，终端设备向接入网设备发送RRC建立完成(RRCSetupComplete)消息。
可选的，RRCSetupComplete消息可以包含NAS层注册请求(Registration request)消息。
其中，NAS层Registration request消息可以是封装在RRCSetupComplete消息的容器(container)中。
S1905，接入网设备向核心网设备发送初始UE信息(Initial UE Message)消息。
可选的，Initial UE Message消息可以包含上述NAS层Registration request消息。
其中，NAS层Registration request消息可以是封装在Initial UE Message消息的容器(container)中。
S1906，终端设备和核心网设备之间进行终端设备的鉴权。
S1907，核心网设备向接入网设备发送初始上下文建立请求(Initial Context Setup Request)消息。
应理解，上述步骤S1901～S1907是可选的步骤，在具体实施例中，在步骤S1908之前，可以执行步骤S1901～S1907，也可以不执行步骤S1901～S1907。
可选的，Initial Context Setup Request消息可以包含NAS层注册接收(Registration Accept)消息。Initial Context Setup Request消息还可以携带终端设备支持的安全信息。
其中，NAS层Registration Accept消息可以是封装在Initial Context Setup Response消息的容器(container)中。
若接入网设备不包含该终端设备的UE能力信息，则执行步骤S1908。
S1908，接入网设备向终端设备发送第七消息，该第七消息用于查询终端设备是否支持CRB。
示例性的，第七消息可以为UE能力查询(UE Capability Enquiry)消息，UE Capability Enquiry消息可以查询UE能力。
S1909，终端设备向接入网设备发送用于指示终端设备支持CRB的能力信息。
示例性的，终端设备可以向接入网设备发送UE能力信息(UE Capability Information)，该UE能力信息可以包含“UE支持CRB”信息。
一种举例说明中，UE能力信息可以通过一个比特位指示终端设备是否支持CRB。例如，若该比特位取值为1，则表示终端设备支持CRB，若该比特位取值为0，则表示终端设备不支持CRB。又例如，若UE能力信息包括该比特位则表示终端设备支持CRB，若UE能力信息不包括该比特位则表示终端设备不支持CRB。
另一种举例说明中，UE能力信息也可以通过多个比特的字段指示终端设备是否支持CRB。例如，UE能力信息包含“CRB supported”指示终端设备支持CRB；UE能力信息包含“CRB unsupported”指示终端设备不支持CRB。
需要说明的是，在终端设备主动上报其CRB的能力信息的情况下，上述步骤S1908可以省略。
S1910，接入网设备保存用于指示终端设备支持CRB的能力信息。
S1911，接入网设备向核心网设备发送用于指示终端设备支持CRB的能力信息。
示例性的，接入网设备可以向核心网设备发送UE无线能力信息指示(UE Radio Capability Info Indication)消息，该UE Radio Capability Info Indication消息用于指示更新UE能力信息，且该UE Radio Capability Info Indication消息携带“UE支持CRB”信息。
一种举例说明中，UE Radio Capability Info Indication消息可以通过一个比特位指示终端设备是否支持CRB。例如，若该比特位取值为1，则表示终端设备支持CRB，若该比特位取值为0，则表示终端设备不支持CRB。又例如，若UE Radio Capability Info Indication消息包括该比特位则表示终端设备支持CRB，若UE Radio Capability Info Indication消息不包括该比特位则表示终端设备不支持CRB。
S1912，接入网设备与终端设备进行安全激活。
一种实现方式为，接入网设备根据Initial Context Setup Request消息携带的UE支持的安全信息向终端设备发送安全模式命令(SecurityModeCommand)消息。终端设备在完成安全激活后向接入网设备发送安全模式完成(SecurityModeComplete)消息。
S1913，接入网设备向终端设备发送RRC重配置(RRCReconfiguration)消息。
可选的，RRCReconfiguration消息可以指示终端设备建立SRB2。
RRCReconfiguration消息还可以包括上述NAS层Registration Accept消息。
其中，NAS层Registration Accept消息可以是封装在RRCReconfiguration消息的容器(container)。
S1914，终端设备向接入网设备发送RRC重配置完成(RRC Reconfiguration Complete)消息。
S1915，接入网设备向核心网设备发送初始上下文建立响应(Initial Context Setup Response)消息，该Initial Context Setup Response消息用于表明UE上下文建立完成。
之后，终端设备可以通过接入网设备向核心网设备发送上行NAS层透传(ULNasTRANs)消息，ULNasTRANs消息包含NAS层Registration complete消息，例如，NAS层Registration complete消息可以是封装在ULNasTRANs消息的container中。
应理解，上述步骤S1912～S1915是可选的步骤，在具体实施例中，在步骤S1911之后，可以执行步骤S1912～S1915，也可以不执行步骤S1912～S1915。
上述方式中，支持CRB的终端设备可以在注册过程中向接入网设备和核心网设备上报UE能力信息，该UE能力信息指示终端设备支持CRB，接入网设备和核心网设备通过保存该终端设备的UE能力信息，可以在后续业务流程中根据终端设备是否支持CRB的能力，按需建立CRB、激活CRB、去激活CRB。
需要说明的是，上述图14所示意的建立CRB的方法应用于终端设备处于RRC连接(connected)态的情况下。在另一种实现方式中，若终端设备处于RRC空闲(idle)态，当终端设备有计算数据待发送时，终端设备可以通过另一种方式建立CRB。下面结合具体场景对建立CRB的过程进行举例说明。终端设备处于RRC idle态，且有计算数据待发送时，终端设备建立CRB的方法如图20所示，该方法包括：
S2001，具体可以参阅上述S1901，这里不再重复赘述。
S2002，接入网设备向终端设备发送RRCSetup消息，RRCSetup消息携带CRB配置信息。
S2003，具体可以参阅上述S1903，这里不再重复赘述。
S2004，终端设备向接入网设备发送RRCSetupComplete消息。其中，RRCSetupComplete消息等同于步骤S1401中的第一消息。
S2005～S2012，具体可以参阅上述S1905～S1912，这里不再重复赘述。
S2013，接入网设备向终端设备发送RRCReconfiguration消息，其中，该RRCReconfiguration消息用于指示终端设备建立CRB，该RRCReconfiguration消息携带CRB配置信息。RRCReconfiguration消息等同于步骤S1402中的第二消息。
一种示例性说明中，CRB配置信息可以包括CRB的PDCP配置(排序递交定时器等)、CRB的RLC模式(确认、非确认、透明)、CRB的上下行RLC层配置(序列号字段长度、重传定时器等)、CRB的逻辑信道标识及优先级配置等。
在一种实施方式中，若RAN-DAM模块与接入网设备独立部署，接入网设备在步骤S2013之后，还可以向RAN-DAM发送指示信息，该指示信息可以用于指示CRB建立完成。
在另一种实现方式中，若RAN-DAM模块与接入网设备集中部署，步骤S2013中，可以是接入网设备的控制面或用户面功能接收RRCReconfiguration消息，并通过接入网设备的内部接口向RAN-DAM发送指示信息，该指示信息可以用于指示CRB建立完成。
S2014，终端设备建立CRB。
S2015～S2016，具体可以参阅步骤S1914～S1915，这里不再重复赘述。
终端设备可以通过该CRB向接入网设备发送计算数据，如RAN计算数据、CN计算数据等。
在一种实现方式中，若该计算数据为RAN计算数据，在RAN-DAM模块与接入网设备独立部署的场景下，接入网设备在接收到终端设备发送的计算数据之后，还可以向RAN-DAM发送该计算数据。
在另一种实现方式中，若该计算数据为RAN计算数据，在RAN-DAM模块与接入网设备集中部署的场景下，可以是接入网设备的控制面或用户面功能接收终端设备发送的计算数据，并通过接入网设备的内部接口向RAN-DAM发送该计算数据。
在一种实现方式中，若该计算数据为CN计算数据，接入网设备在接收到终端设备发送的计算数据之后，可以向核心网设备发送该计算数据。
上述方式中，可以在RRC重配置流程的基础增加对CRB的支持，从而终端设备可以在由RRC idle态进入RRC连接态时建立CRB，进而可以通过CRB传输计算数据。
通常地，在终端设备与接入网设备完成了通过CRB传输计算数据后，可以释放该CRB；或者在终端设备进入RRC idle态时，也应该释放所有CRB。在一个可能的示例中，终端设备在建立CRB之后，可以在接入网设备的指示下释放该CRB，例如，终端设备接收接入网设备发送的第三消息，第三消息用于释放CRB；终端设备释放CRB。在另一种可能的示例中，终端设备可以在由RRC连接态进入RRC idle态过程中释放CRB。例如，接入网设备向终端设备发送RRC释放(RRC Release)消息，终端设备在接收到RRC Release消息之后释放CRB，其中，RRC Release消息为第三消息。
在一种实现方式中，若RAN-DAM模块与接入网设备独立部署，接入网设备在向终端设备发送第三消息之后，可以向RAN-DAM发送用于指示CRB已被删除的消息，例如，如图21a所示。
在另一种实现方式中，若RAN-DAM模块与接入网设备集成部署，第三消息可以是接入网设备的控制面或用户面功能发送的，接入网设备的控制面或用户面功能在向终端设备发送第三消息之后，还可以通过接入网设备的内部接口向接入网设备的RAN-DAM发送用于指示CRB删除的信息，例如，如图21b所示。
当终端设备释放CRB时，通过通知RAN-DAM：CRB释放，使得RAN-DAM可以记录CRB的状态，从而可以避免出现RAN-DAM不知道CRB已被释放而将计算数据发送给RAN导致数据传输失败等场景。
除了释放CRB外，在一些情况下，终端设备和接入网设备可以将已建立的CRB去激活。在一种可能的示例中，终端设备在建立CRB之后，还可以在接入网设备的指示下去激活该CRB，例如，终端设备接收接入网设备发送的第四消息，第四消息用于去激活CRB；终端设备将CRB去激活。在另一种可能的示例中，终端设备可以在由连接态进入RRC去激活(inactive)态过程中去激活CRB。例如，接入网设备向终端设备发送携带挂起配置(suspendConfig)信元的RRCRelease消息，该suspendConfig信元用于指示终端设备挂起(或者去激活)RRC连接。终端设备在接收到该RRCRelease消息之后去激活CRB，其中，该携带suspendConfig信元的RRCRelease消息为第四消息。
在一种实现方式中，若RAN-DAM模块与接入网设备独立部署，接入网设备在向终端设备发送携带suspendConfig信元的RRCRelease消息之后，可以向RAN-DAM发送用于指示CRB已被挂起的消息。
在另一种实现方式中，若RAN-DAM模块与接入网设备集中部署，携带suspendConfig信元的RRCRelease消息可以是接入网设备的控制面或者用户面功能发送的，接入网设备的控制面或者用户面功能在发送携带suspendConfig信元的RRCRelease消息之后，还可以通过接入网设备的内部接口向接入网设备的RAN-DAM发送用于指示CRB已被挂起的信息，例如，如图22示。
其中，“CRB挂起”也可以理解为“CRB处于去激活态”。
当终端设备去激活CRB时，通过通知RAN-DAM：CRB挂起，使得RAN-DAM可以停止发送计算数据，从而可以避免出现RAN-DAM将计算数据发送给RAN，而终端设备的CRB被去激活等场景。
可选的，终端设备将CRB去激活后，若终端设备有计算数据需要发送，还可以向接入网设备请求激活该CRB，例如，终端设备向接入网设备发送第五消息，第五消息用于请求接入网设备激活CRB；终端设备接收接入网设备发送的第六消息，第六消息用于指示终端设备激活CRB；终端设备激活CRB。
一种可能的示例中，若终端设备将CRB去激活后有计算数据需要发送，可以由inactive态进入连接态，从而可以在由RRC inactive态进入RRC连接态过程中激活CRB。例如，如图23所示，终端设备激活CRB的过程可以包括：
S2301，终端设备可以向接入网设备发送RRC恢复请求(RRCResumeRequest)消息，其中，RRCResumeRequest消息为第五消息。
S2302，接入网设备向终端设备发送RRC恢复(RRCResume)消息，其中，RRCResume消息为第六消息。
S2303，终端设备激活CRB。
S2304，终端设备向接入网设备发送RRC恢复完成(RRCResumeComplete)消息。
S2305，终端设备通过CRB向接入网设备发送计算数据。
在一种实现方式中，若该计算数据为RAN计算数据，在RAN-DAM模块与接入网设备独立部署的场景下，接入网设备在接收到终端设备发送的计算数据之后，还可以向RAN-DAM发送该计算数据。RAN-DAM在接收到计算数据后可以对计算数据进行处理，例如，以计算数据为AI模型为例，RAN-DAM在接收到计算数据后可以将计算模型进行融合。
在另一种实现方式中，若该计算数据为RAN计算数据，在RAN-DAM模块与接入网设备集中部署的场景下，终端设备向接入网设备发送计算数据时，可以是接入网设备的控制面或用户面功能接收计算数据，并通过接入网设备的内部接口向RAN-DAM发送该计算数据。RAN-DAM在接收到计算数据后可以对计算数据进行处理，例如，以计算数据为AI模型为例，RAN-DAM在接收到计算数据后可以将计算模型进行融合。
再一种实现方式中，若该计算数据为CN计算数据，接入网设备在接收到终端设备发送的计算数据之后，还可以向核心网设备发送该计算数据。
上述方式，处于RRC inactive态的终端设备在需要发送计算数据时，通过RRC Resume流程恢复在终端设备和接入网设备之间CRB，从而可以通过CRB将计算数据(如AI/ML模型)发送给RAN-DAM。
或者，终端设备将CRB去激活后，还可以在接入网设备的指示下释放该CRB，例如，终端设备接收接入网设备发送的第三消息，第三消息用于指示终端设备释放CRB；终端设备释放CRB。
一种可能的示例中，终端设备可以在由RRC inactive态进入RRC idle态过程中释放CRB。例如，接入网设备向终端设备发送RRC Release消息，终端设备在接收到RRC Release消息之后去激活CRB，其中，RRC Release消息为第三消息。
在一种实现方式中，若RAN-DAM模块与接入网设备独立部署，接入网设备在向终端设备发送第三消息之后，可以向RAN-DAM发送用于指示CRB已被删除的消息。
在另一种实现方式中，若RAN-DAM模块与接入网设备集中部署，第三消息可以是接入网设备的控制面或用户面功能发送的，接入网设备的控制面或用户面功能在向终端设备发送第三消息之后，还可以通过接入网设备的内部接口向接入网设备的RAN-DAM发送用于指示CRB已被删除的信息，例如，如图24示。
当终端设备释放CRB时，通过通知RAN-DAM：CRB释放，使得RAN-DAM可以记录CRB的状态，从而可以避免出现RAN-DAM由于不知道CRB已被释放而将计算数据发送给RAN导致数据传输失败等场景。
