技术领域
本发明涉及通信技术领域，尤其涉及一种业务发送方法、业务发送模式配置方法及相关设备。
背景技术
长期演进(Long Term Evolution，LTE)多媒体广播多播业务(Multimedia Broadcast and Multicast Service，MBMS)支持MBMS单频网(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)方式和单小区点到多点(Single Cell Point to Multipoint，SC-PTM)方式进行广播或多播传输。这两种方式在空口都是通过广播方式发送多播业务相关的控制信息，通过广播或组播方式发送数据信息。如果要实现多播和单播的切换，则只能从核心网到无线接入网(Radio Access Network，RAN)建立单播连接，时延较长。
在新接入(New Radio，NR)的多播业务中，RAN侧可以采用单播方式或者多播方式发送多播业务的数据给用户设备(User Equipment，UE)。然而现有技术中，RAN侧对多播业务的发送模式的选择，往往仅是基于RAN侧对多播业务需求的统计结果进行决策，不仅决策依据较为单一，还容易导致多播业务的发送难以满足可靠性等服务质量要求。
发明内容
本发明实施例提供一种业务发送方法、业务发送模式配置方法及相关设备，以解决现有技术中多播业务的发送难以满足可靠性等服务质量要求的问题。
为了解决上述技术问题，本发明是这样实现的：

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例，例如除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B和/或C，表示包含单独A，单独B，单独C，以及A和B都存在，B和C都存在，A和C都存在，以及A、B和C都存在的7种情况。
为了便于理解，以下对本发明实施例涉及的一些内容进行说明：
一、多媒体广播多播业务(Multimedia Broadcast and Multicast Service，MBMS)或多播广播业务(Multicast Broadcast Service，MBS)：
在长期演进(Long Term Evolution，LTE)系统中，MBMS业务可以通过以下两种方式发送：
MBMS/MBS发送方式一：通过在MBMS单频网(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)子帧中通过物理多播信道(Physical Multicast Channel，PMCH)发送。其中，控制信息可通过系统信息(如，SIB13)和广播控制信道(Multicast Control Channel，MCCH)发送，数据可通过MTCH(Multicast Traffic Channel，广播业务信道)发送。
MBMS/MBS发送方式二：通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度的物理下行控制信道(Physical Downlink Shared Channel，PDSCH)信道发送。其中，控制信息可通过系统信息(如，SIB20)和单小区广播控制信道(Single Cell Multicast Control Channel，SC-MCCH)发送，数据可通过单小区广播业务信道(Single Cell Multicast Traffic Channel，SC-MTCH)发送。其中，SC-MCCH通过单小区无线网络临时标识(Single Cell Radio Network Temporary Identity，SC-RNTI)PDCCH调度的PDSCH发送，SC-MTCH通过组呼无线网络临时标识(Group Radio Network Temporary Identity，G-RNTI)PDCCH调度的PDSCH发送。
二、LTE计数功能：
在LTE中，由多小区/多播协调实体(Multi-cell/Multicast Coordination Entity，MCE)触发无线接入网(Radio Access Network，RAN)侧进行用户数量统计，MCE根据接收到的统计结果，决定是采用单小区点到多点(Single Cell Point to Multipoint，SC-PTM)(也即单小区多播)还是MBSFN(也即多小区多播)。也就是说，该统计结果并不会反馈到核心网节点，对某多播业务，其核心网仍保持多播数据通道，只是RAN侧根据统计结果决定将从核心网多播数据通道接收到的数据是在单小区多播还是多小区多播。
具体地，MBMS业务用户数量统计可以如图1所示，包括如下步骤：
步骤S1、MCE向eNB发送MBMS业务计数请求。
步骤S2、eNB向MCE返回MBMS业务计数响应。
步骤S3、eNB向UE发送MCCH变更通知。
步骤S4、eNB向UE发送MBMS计数请求。
步骤S5、UE向eNB返回MBMS计数响应。
步骤S6、eNB向MCE上报MBMS业务计数结果。
参见图2，图2是本发明实施例可应用的一种网络系统的结构图，如图2所示，包括接入网侧设备11和核心网侧设备12。其中，接入网侧设备11可以是基站，例如：宏站、LTE eNB、5G NR NB、gNB等，或者接入网侧设备11可以是小站，如低功率节点(Low Power Node，LPN)pico、femto等小站，或者接入网侧设备11可以是接入点(Access Point，AP)，在本发明实施例中 并不限定接入网侧设备11的具体类型。
需要说明的是，本发明实施例提供的业务发送方法可以由上述接入网侧设备11执行，本发明实施例提供的业务发送模式配置方法可以由上述核心网侧设备12执行，详细说明请参见下述描述。
本发明实施例提供一种业务发送方法，应用于接入网侧设备。参见图3，图3是本发明实施例提供的一种业务发送方法的流程图，如图3所示，包括以下步骤：
步骤301、从核心网侧设备接收第一消息，其中，所述第一消息包括多播业务标识和模式策略信息。
本实施例中，上述多播业务标识可以是任一可以标识多播业务的信息，例如，临时移动组标识(Temporary Mobile Group Identity，TMGI)。上述多播业务标识对应的多播业务可以包括但不限于MBMS业务或者MBS业务等。
上述模式策略信息可以用于确定或是指示上述多播业务标识对应的多播业务的发送模式，其中，上述模式策略信息可以包括但不限于发送模式类型、业务质量要求信息等中的一项或多项。可选地，上述模式策略信息可以是核心网侧设备基于上述多播业务标识对应的多播业务的服务质量需求、多播业务的用户数量的统计结果等确定的信息。
步骤302、利用第一发送模式发送所述多播业务标识对应的多播业务的数据；其中，所述第一发送模式为根据所述模式策略信息确定的发送模式，或者所述第一发送模式为所述模式策略信息指示的发送模式。
本实施例中，接入网侧设备可以基于核心网侧设备发送的模式策略信息决策其发送多播业务标识对应的多播业务的数据的发送模式。其中，上述多播业务的发送模式可以包括单播模式、多播模式等，上述单播模式可以包括点到点(Point to Point，PTP)模式，上述多播模式可以包括点到多点(Point to Multipoint，PTM)模式。
例如，在协议预定义核心网侧设备发送的模式策略信息作为参考信息(也可称为参考依据)的情况下，接入网侧设备可以参考模式策略信息确定第一发送模式发送所述多播业务标识对应的多播业务的数据，在协议预定义核心网侧设备发送的模式策略信息作为强制指示信息(也可称为唯一依据)的情 况下，接入网侧设备可以直接利用模式策略信息指示的发送模式发送所述多播业务标识对应的多播业务的数据；或者核心网侧设备可以指示接入网侧设备该模式策略信息是作为参考信息还是强制指示信息，这样接入网侧设备可以基于核心网侧设备的指示，确定是参考所述模式策略信息确定一发送模式发送所述多播业务标识对应的多播业务的数据，还是直接利用模式策略信息指示的发送模式发送所述多播业务标识对应的多播业务的数据。
需要说明的是，在接入网侧设备根据模式策略信息确定第一发送模式发送多播业务的数据的情况下，接入网侧设备可以仅根据模式策略信息决策该多播业务的数据的发送模式，例如，在模式策略信息包括业务质量要求信息的情况下，若该业务质量要求信息中的可靠性要求较高，则可以采用PTP模式发送该多播业务的数据，否则可以采用PTM模式发送该多播业务的数据；接入网侧设备也可以综合模式策略信息和其他模式参数共同决策多播业务的数据的发送模式，例如，可以综合模式策略信息、多播业务的用户数量的统计结果、接入网侧设备的资源情况等共同确定该多播业务的数据的发送模式。
本发明实施例提供的业务发送方法，通过从核心网侧设备接收第一消息，其中，所述第一消息包括多播业务标识和模式策略信息；利用第一发送模式发送所述多播业务标识对应的多播业务的数据；其中，所述第一发送模式为根据所述模式策略信息确定的发送模式，或者所述第一发送模式为所述模式策略信息指示的发送模式。基于核心网侧设备发送的模式策略信息确定的发送模式或者指示的发送模式发送多播业务标识对应的多播业务的数据，不仅为多播业务的发送模式的决策提供了一种不同于现有技术的决策依据，还可以使得多播业务的发送更为符合服务质量要求。
可选地，所述模式策略信息包含发送模式类型或业务质量要求信息。
在一实施方式中，核心网侧设备可以显示地向接入网侧设备指示多播业务的数据的发送模式，例如，可以直接在第一消息中携带发送模式类型，例如，PTP模式或者PTM模式。
相应地，接入网设备可以直接利用该发送模式类型指示的发送模式发送多播业务的数据，也即该发送模式类型作为该多播业务的发送模式决策的唯一依据，例如，若该发送模式类型为PTP模式，则利用PTP模式发送多播业 务的数据，若该发送模式类型为PTM模式，则利用PTM模式发送多播业务的数据；或者接入网设备也可以参考该发送模式类型确定一发送模式发送多播业务的数据，也即该发送模式类型作为该多播业务的发送模式决策的参考依据，例如，发送模式类型为PTM模式，而接入网侧设备综合该发送模式类型和多播业务的用户数量确定采用PTP模式发送多播业务。
在另一实施方式中，核心网侧设备可以隐式地向接入网侧设备指示多播业务的数据的发送模式，例如，可以在第一消息中携带业务质量要求信息，并可以预先建立不同业务质量要求信息和不同发送模式之间的对应关系，这样基于该对应关系和第一消息中携带的业务质量要求信息可以得到该业务质量要求信息对应的发送模式。
相应地，接入网设备可以直接利用该业务质量要求信息隐式指示的发送模式发送多播业务的数据，也即该发送模式类型作为该多播业务的发送模式决策的唯一依据，例如，若该业务质量要求信息隐式指示的发送模式为PTP模式，则利用PTP模式发送多播业务的数据，若该业务质量要求信息隐式指示的发送模式为PTM模式，则利用PTM模式发送多播业务的数据；或者接入网设备也可以参考该业务质量要求信息确定一发送模式发送多播业务的数据，也即该业务质量要求信息作为该多播业务的发送模式决策的参考依据，例如，该业务质量要求信息隐式指示的发送模式为PTM模式，而接入网侧设备综合该业务质量要求信息和接入网侧设备的无线资源情况确定采用PTP模式发送多播业务。
可选地，所述第一消息还包括判决指示；
其中，在所述判决指示为第一指示的情况下，所述第一发送模式为根据所述模式策略信息确定的发送模式；
和/或
在所述判决指示为第二指示的情况下，所述第一发送模式为所述模式策略信息指示的发送模式。
