一种传输方式确定方法、装置、设备及存储介质
相关申请的交叉引用
本申请要求于2020年05月15日提交的申请号为2020104150361，发明名称为“一种传输方式确定方法、装置、设备及存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本申请涉及通信技术领域，尤其涉及一种传输方式确定方法、装置、设备及存储介质。
背景技术
IP(Internet Protocol，网际互连协议)网络中采用的数据传输方式包括单播、组播与广播。单播(unicast)是指“一对一通信”，即数据由一个设备发送到一个接收设备；而组播(Multicast)/广播(Broadcast)是指“一对多通信”，即相同的数据，通过共享信道和内容复制等技术，由一个设备发送到多个接收设备。与单播相比，组播/广播具有更高的网络资源使用效率。组播与广播的不同在于：组播的接收设备通过签约和/或加入组来接收特定的组播业务内容(即数据)，以及解除签约和/或离开组来终止接收该业务内容；而广播区域或网络内的任意设备都可以接收广播的内容，不需要签约或加入组。
目前，5G(5th generation，第五代)移动通信系统可以支持单播传输方式。并且，5G移动通信系统为了支持更多的业务，将支持组播/广播的数据传输方式。因此，在5G移动通信系统中，如何更好地管理这些不同的数据传输方式则是当前亟待解决的问题。

目前，5G移动通信系统可以支持单播传输方式。并且，5G移动通信系统为了支持更多的业务，将支持组播/广播的数据传输方式。因此，在5G移 动通信系统中，如何更好地管理这些不同的数据传输方式则是当前亟待解决的问题。
对于5G MBS(Multicast Broadcast Service，组播广播业务)，AN(Access Network，接入网)需要确定AN与UE之间的数据传输方式，即无线传输方式(单播，或组播/广播)，还需要依据UE或网络状况的变化调整传输方式(由单播改变为组播/广播，或反之)，从而采用或调整相应的无线资源配置，达到优化资源使用和提高通信性能的目的。
但是，AN(Access Network，接入网)依据自身统计和本地策略确定采用何种传输方式以及传输方式的转换，实现复杂度较高，并且整个网络缺乏对AN传输方式的统一控制，不利于网络整体性能的优化。
针对上述问题，本申请实施例提供一种传输方式确定方法、装置、设备及存储介质，以实现网络对AN传输方式的统一控制，优化网络整体性能。
下面通过具体实施例进行说明。
图1为本申请实施例提供的一种传输方式确定方法的流程图，该方法可以用于AN设备；如图1所示，该方法可以包括如下步骤：
S101、接收CN(Core Network，核心网)功能或OAM(Operation Administration and Maintenance，操作管理维护)平台发送的MBS辅助信息。
具体地，MBS辅助信息是CN设备或OAM平台为AN设备提供的用于确定MBS业务的无线传输方式和/或无线资源的辅助信息。
其中，CN设备可以为AF(Application Function，应用功能)、PCF(Policy Control Function，策略控制功能)、SMF(Session Management Function，会话管理功能)等网络设备。
S102、根据MBS辅助信息确定MBS业务的无线传输方式和/或无线资源。
具体地，MBS业务的无线传输方式可以包括单播、组播或广播等传输方式。MBS业务的无线传输方式用于表征AN设备与UE之间用于传输MBS数据的无线资源对应的传输方式。
由上述实施例可见，通过接收CN设备或OAM平台发送的MBS辅助信息，根据MBS辅助信息确定MBS业务的无线传输方式和/或无线资源，从而 提高了网络对AN传输方式的统一控制，优化了网络整体性能，还提高了传输方式确定的准确性。
进一步地，建立在上述方法的基础上，上述S102中的MBS业务可以包括正在建立或修改的第一MBS会话或QoS(Quality of Service，业务质量)流，和/或正在进行数据传输的第二MBS会话或QoS流。
由上述实施例可见，可以根据MBS辅助信息确定正在建立或修改的第一MBS会话或QoS流，和/或正在进行数据传输的第二MBS会话或QoS流的无线传输方式和/或无线资源，从而降低了AN设备确定传输方式的复杂度，提高了传输方式确定的效率。
进一步地，建立在上述方法的基础上，上述S101中的MBS辅助信息可以包括但不限于以下信息之一或组合：
(1)第一用户设备UE数目，所述第一UE数目用于指示若所述AN设备或所述AN设备的小区下正在或期望接收MBS业务或会话的UE的数目达到所述第一UE数目，建议所述AN设备采用组播或广播方式传输所述MBS业务或会话。
具体地，第一UE数目可以指的是CN设备或OAM平台建议的UE数量。
另外，AN设备统计该AN设备或该AN设备下的每个小区或特定小区内正在或期望接收特定MBS业务/会话的UE数目达到该建议的UE数目时，AN设备可以确定采用组播或广播传输方式，或将传输方式由单播传输方式改变为组播或广播传输方式。
(2)第二UE数目，所述第二UE数目为CN或OAM统计或预测的所述AN设备或所述AN设备的小区下正在或期望接收MBS业务或会话的UE的数目。
具体地，第二UE数目可以指的是CN设备或OAM平台统计或预测的UE数量。
另外，AN设备可以根据该统计或预测的UE数量或本地策略(例如该数目大于相应预设值时采用组播或广播)，确定采用组播或广播传输方式，或将传输方式由单播传输方式改变为组播或广播传输方式。
(3)指定业务或应用或会话或QoS流的传输方式信息。
具体地，指定业务或应用或会话或QoS流的传输方式信息可以包括对指定业务或应用或会话或QoS流，是否允许采用组播或广播或单播传输方式，是否允许传输方式的改变等。
若指定业务/应用/会话或QoS flow只允许采用某一种传输方式(例如组播(/广播))，则AN设备只采用该传输方式，不能采用或改用另一种传输方式。
其中，上述(3)所示辅助信息与网络策略有关，例如：网络拥塞情况下为了限制对网络资源的使用，要求指定业务/应用/会话或QoS流只能使用组播或广播传输方式；为了保证指定业务/应用/会话或QoS流的服务质量，要求指定业务/应用/会话或QoS流只能用单播传输方式。
可选地，上述(3)中的指定业务或应用或会话或QoS流的传输方式信息可以包括：所述指定业务或应用或会话或QoS流仅允许采用组播或广播方式传输，或仅允许采用单播方式传输，或单播方式和组播或广播方式均允许采用。
(4)UE签约的MBS业务信息。
具体地，UE签约的MBS业务的标识，可以采用TMGI(Temporary Mobile Group Identity，临时移动组标识)表示。
当UE通过空口请求特定MBS业务时，AN可以检查UE签约的MBS业务信息；只有当UE签约了该MBS业务，AN才会依据UE的请求下发MBS业务数据，或触发CN下发MBS业务数据。
(5)UE传输方式能力信息。
具体地，UE传输方式能力信息，例如：UE是否支持组播(或广播)和单播数据同时传输，UE是否支持组播(或广播)和单播的转换，等。
若UE不支持组播(或广播)和单播数据同时传输，则AN设备将UE正在进行的业务的传输方式确定为新的业务的传输方式，即：不改变UE使用的传输方式；
若UE不支持组播(或广播)和单播的转换，则AN不改变UE正在进行的业务的传输方式。
(6)AN性能信息。
具体地，AN性能信息可以指的是CN统计或预测的AN性能信息。其中，AN性能信息可以包括：
AN状态；例如AN或AN下每个小区或特定小区的i)荷载，ii)资源使用，iv)拥塞情况，等；

另外，AN可以依据CN统计或预测的AN性能信息，以及本地策略(例如AN或AN的一个小区的荷载达到70％或拥塞级别为中高时，采用组播/广播)，确定新的或现有业务的传输方式，(例如，采用组播/广播传输新的MBS业务，或将现有的MBS业务改用组播/广播传输方式传输；或者，
AN可以依据CN统计或预测的AN性能信息，以及CN提供的策略，确定新的或现有业务的传输方式。
(7)对AN指定性能下AN采用的传输方式的建议信息。
具体地，例如：当满足以下条件之一或多个时，采用组播或广播传输新的MBS业务，或将现有的MBS业务改用组播或广播传输方式传输：
1)AN或AN的一个小区的荷载达到70％或拥塞级别为中高。
2)AN中或AN的一个小区中特定UE、特定UE群组(例如接收同一MBS业务的UE)、60％的UE或所有UE的采用单播传输的会话建立成功率低于70％。
3)AN或AN的一个小区中50％的UE的峰值速率高于200M。
另外，AN可以依据该CN提供的策略，以及AN本地测量的AN状态或通信性能，确定新的或现有业务的传输方式。
(8)CN性能信息。
具体地，CN设备的状态，例如：荷载，拥塞情况。
另外，AN可以依据CN性能信息，以及本地策略(例如AMF的荷载达到 70％或拥塞级别为中高时，采用组播或广播)，确定新的或现有业务的传输方式。或者，
AN可以依据CN性能信息，以及CN提供的策略，确定新的或现有业务的传输方式。
(9)对CN指定性能下AN采用的传输方式的建议信息或建议策略。
具体地，例如：当CN设备的荷载达到70％或拥塞级别为中高时，采用组播或广播传输新的MBS业务，或将现有的MBS业务改用组播或广播传输方式传输，以减少对CN控制面和/或用户面资源的需求。
AN可以依据该CN提供的策略，以及AN本地信息(例如尝试接入AMF失败的次数)，确定新的或现有业务的传输方式，例如连续尝试接入AMF失败>4次，则改用组播/广播传输方式。
由上述实施例可见，可以根据MBS辅助信息中包括的信息之一或组合，确定MBS业务的无线传输方式和/或无线资源，从而丰富了AN设备确定传输方式的实现方式，提高了传输方式确定的可靠性。

S103、根据所述AN设备本地测量或所述第二UE数目，确定第三UE数目，所述第三UE数目为所述AN设备或所述AN设备的小区下接收所述MBS业务或会话的UE的数目；
S104、若所述第三UE数目达到第四UE数目，所述第四UE数目为所述第一UE数目或所述AN设备根据本地策略确定的采用组播或广播方式传输所述MBS业务或会话的最小接收UE数目，则所述AN设备确定所述MBS业务或会话的无线传输方式为组播或广播无线传输方式，和/或所述MBS业务或会话的无线资源为组播或广播无线资源。
由上述实施例可见，若AN设备或所述AN设备的小区下接收MBS业务或会话的UE的数目，达到第一UE数目或所述AN设备根据本地策略确定的最小接收UE数目，就可以确定将所述MBS业务或会话的无线传输方式为组播或广播无线传输方式，和/或所述MBS业务或会话的无线资源为组播或广播无线资源，从而实现了通过MBS辅助信息和AN设备本地策略二者结合来 进行传输方式确定，提高了传输方式确定的准确性。
进一步地，建立在上述方法的基础上，该方法还可以包括：

具体地，SMF向AMF发起Namf_Communication_N1N2MessageTransfer服务请求，其中携带N2消息，N2消息中携带MBS辅助信息。AMF将N2消息转发给AN设备。
示例3：AN设备利用MBS辅助信息的详细流程，如图5所示。
S1、UE-1、UE-2…UE-N通过AN节点或AN节点的同一个小区(例如小区1)，采用单播无线传输方式接收该MBS业务。
具体地，
1a-1.UE-1(UE-2…UE-N)可以向AN，或通过AN向CN，指示对该MBS业务感兴趣，即希望接收该MBS业务。具体地，UE-1(UE-2…UE-N)可以通过小区广播信息获知该小区支持哪些MBS业务，进而执行以下操作之一或组合，来向AN或CN指示希望接收该MBS业务：
a)向AN发送RRC消息，其中携带感兴趣(即希望接收)的MBS业务的标识，例如TMGI；
b)向AN发送RRC消息，其中携带发送给CN的NAS消息(例如PDU会话建立请求或PDU会话修改请求)，该NAS消息中携带感兴趣(即希望接收)的MBS业务的标识，例如TMGI；
c)利用已建立的PDU会话的用户面(即数据面)资源，通过AN向CN发送应用层的MBS业务请求消息(例如IGMP Join消息)。
若UE-N+1采用步骤1a-1中的上述b)或c)请求接收该MBS业务(即UE-1通过AN向CN指示希望接收该MBS业务)，CN向AN发送N2消息，其中携带UE-1的标识、UE-1请求加入的该MBS业务的信息(例如TMGI、Application ID)、该MBS业务对应的QoS flow的QoS参数(例如5QI)等，请求AN为UE-1建立无线资源以接收该MBS业务数据。
1a-2.AN根据MBS辅助信息中CN建议AN采用组播(或广播)方式的特定MBS业务/会话的UE数目(简称建议的UE数目)，若AN节点或AN节点的小区1中当前接收该MBS业务/会话的UE数目(考虑到增加UE-1)未达到建议的UE数目,则AN确定采用单播无线传输方式，从而为UE-1分配单播无线传输方式对应的无线资源，并将无线资源配置发送给UE-1，UE-1据此建立接收该MBS业务/会话数据的单播无线资源。
其中，AN节点或AN节点的小区1中当前接收该MBS业务/会话的UE数目，可以是AN依据MBS辅助信息中CN统计的正在或期望接收该特定MBS业务/会话的UE数目来确定，或AN依据自身测量或估计的正在或期望接收该特定MBS业务/会话的UE数目来确定。
具体地，若UE-1采用步骤1a-1中的a)请求接收该MBS业务(即UE向AN指示希望接收该MBS业务)，AN可以依据MBS辅助信息中UE-1签约的MBS业务信息，若该MBS业务包括在UE-1签约的MBS业务信息中，则AN确定需要建立UE-1与AN之间用于传输该MBS业务数据的无线资源，从而继续为UE-1确定传输该MBS业务数据的无线传输方式和无线资源；否则AN拒绝UE-1接收该MBS业务的请求。
具体地，若MBS辅助信息中包含特定业务/应用/会话或QoS flow的传输方式信息，AN还需要依据该辅助信息，以及该MBS业务的信息(例如TMGI、 Application ID)或该MBS业务对应的QoS flow的QoS参数(例如5QI)，确定该MBS业务/应用/会话或QoS flow允许采用的无线传输方式和/或是否允许传输方式的改变，若只允许采用单播(/组播)，则AN只能对UE-N+1采用单播无线传输方式；若(该MBS业务/会话建立后)不允许传输方式改变，AN也可以考虑/估计后续该MBS业务的趋势(例如是否会有很多UE加入该业务)，来确定采用单播还是组播传输该MBS业务/会话数据。
1a-3.UE-1采用单播无线传输方式开始接收该MBS业务的数据。
1b/1c.UE-2…UE-N加入/接收MBS业务数据并采用单播无线传输方式开始接收该MBS业务的数据的过程与此相似。
S2、AN节点或AN节点的小区1下的UE-N+1(即第N+1个UE)向AN，或通过AN向CN，指示对该MBS业务感兴趣，即希望接收该MBS业务。
S3、若UE-N+1采用步骤1a-1中的b)或c)请求接收该MBS业务(即UE-N+1通过AN向CN指示希望接收该MBS业务)，CN向AN发送N2消息，其中携带UE-N+1的标识、UE-N+1请求加入的该MBS业务的信息(例如TMGI、Application ID)、该MBS业务对应的QoS flow的QoS参数(例如5QI)等，请求AN为UE-N+1建立无线资源以接收该MBS业务数据。
S4、AN根据MBS辅助信息中建议的UE数目，确定此时AN节点或AN节点的小区1中接收该MBS业务/会话的UE数目(考虑到增加UE-N+1)达到建议的UE数目，从而决定该AN节点或AN节点的小区1中改用组播无线传输方式传输该MBS业务/会话。
具体地，若UE-N+1采用1a-1中的a)请求接收该MBS业务(即UE向AN指示希望接收该MBS业务)，AN可以依据MBS辅助信息中UE-N+1签约的MBS业务信息，若该MBS业务包括在UE-N+1签约的MBS业务信息中，则AN确定需要建立UE-N+1与AN之间用于传输该MBS业务数据的无线资源，从而继续为UE-N+1确定传输该MBS业务数据的无线传输方式和无线资源；否则AN拒绝UE-N+1接收该MBS业务的请求，流程至此终止。
具体地，若MBS辅助信息中包含特定业务/应用/会话或QoS flow的传输方式信息，AN还需要依据该辅助信息，以及该MBS业务的信息(例如TMGI、 Application ID)或该MBS业务对应的QoS flow的QoS参数(例如5QI)，确定该MBS业务/应用/会话或QoS flow允许采用的无线传输方式和/或是否允许传输方式的改变，若只允许采用单播(/组播)，或(会话建立后)不允许传输方式改变，则AN只能对UE-N+1采用单播无线传输方式，为UE-N+1分配单播无线传输方式对应的无线资源，并将无线资源配置发送给UE-N+1，UE-N+1据此建立单播无线资源来接收该MBS业务/会话数据。后续步骤不再执行。
S5、AN分配传输该MBS业务/会话的组播无线资源。UE-1、UE-2…UE-N+1据此建立组播无线资源，用来接收该MBS业务/会话的数据。
具体地，可以通过以下方式a或b:
方式a:
5a-1.AN向UE-N+1发送RRC消息，请求建立传输该MBS业务/会话数据的组播无线资源。5a-2.AN向UE-1、UE-2…UE-N发送RRC消息，请求UE-1、UE-2…UE-N将用于接收该MBS业务/会话数据的单播无线资源修改为组播无线资源。
方式b.
5b-1.AN建立传输该MBS业务/会话数据的组播无线资源。UE-N+1通过组播无线资源接收该MBS业务/会话数据。
5b-2.AN向UE-1、UE-2…UE-N发送RRC消息，其中携带该MBS业务/会话改用组播无线传输方式(或组播无线资源)的指示；UE-1、UE-2…UE-N依据该指示改用组播无线资源接收该MBS业务/会话数据，并释放相应的单播无线资源。或，UE-1、UE-2…UE-N检测到传输该MBS业务/会话数据的组播无线资源(例如特定的组播无线信道/时隙slot中传输该MBS业务/会话的TMGI)，则UE-1、UE-2…UE-N改用组播无线资源接收该MBS业务/会话数据，并释放相应的单播无线资源。
UE-1、UE-2…UE-N+1开始采用组播无线传输方式接收该MBS业务的数据。
示例4：CN设备或OAM平台向AN设备提供MBS辅助信息，如图6所示。
S1、AN节点或AN节点的一个或多个小区从CN接收MBS业务数据。UE-1、UE-2…UE-N通过该AN节点或AN节点的同一个小区(例如小区1)，采用单播无线传输方式接收该MBS业务。
S2、AN节点收到CN更新的MBS辅助信息，或定期检查MBS辅助信息，或本地检测到AN或CN性能的变化(例如AN荷载较高，或CN持续拒绝发自AN的消息)，或在其它事件/条件触发下，AN依据MBS辅助信息中的AN性能信息和/或CN对AN特定状态或通信性能下AN采用的传输方式的建议信息(/建议策略)，和/或，MBS辅助信息中的CN性能信息和/或CN对CN特定性能下AN采用的传输方式的建议信息(/建议策略)，确定将该AN节点或AN节点的小区1中该MBS业务的无线传输方式改为组播。
S3、AN分配传输该MBS业务/会话的组播无线资源。UE-1、UE-2…UE-N建立组播无线资源，用来接收该MBS业务/会话的数据。
