在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本发明的实施例。本发明实施例提供的一种MBS业务传输方法、MBS业务传输控制方法及相关设备可以应用于无线通信系统中。该无线通信系统可以为5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
请参见图1，图1是本发明实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。上述网络设备12可以是5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者发送接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)， 或者辅节点(Secondary Node，SN)。需要说明的是，在本发明实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
请参见图2，图2是本发明实施例提供的一种MBS业务传输方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201，在所述终端处于空闲态或者非激活态接收MBS业务、且满足小区重选条件的情况下，根据所述MBS业务的相关信息确定重选的目标小区；
步骤202，基于所述目标小区接收所述MBS业务；
其中，所述相关信息包括第一配置信息的生效区域信息和/或支持所述MBS业务的小区信息，所述第一配置信息用于所述终端在原小区接收所述MBS业务。
本发明实施例中，终端在原小区处于连接态下，可以获取该原小区广播的MBS业务的第一配置信息，终端基于该第一配置信息可以接收MBS业务。其中，接收的MBS业务可以理解为感兴趣的MBS业务，例如，终端可以基于用户的选择确定接收的MBS业务，接收的该MBS业务可以包括一个或者多个业务。
需要说明的是，上述相关信息由网络设备发送，当在MBS业务的第一配置信息仅原小区生效，此时网络设备可以默认不指示生效区域信息，或者不指示相关信息。
也就是说，本实施例中，所述在所述终端处于空闲态或者非激活态接收MBS业务、且满足小区重选条件的情况下，根据所述MBS业务的相关信息确定重选的目标小区之前，所述方法还包括：
接收网络设备发送的所述第一配置信息；
或者，接收网络设备发送的所述第一配置信息及所述相关信息。
上述第一配置信息可以包括临时移动组标识(Temporary Mobile Group Identity，TMGI)、业务周期、非连续接收(Discontinuous Reception，DRX)信息、业务配置信息、业务调度和传输信息等。例如，可以包括集群组无线网络临时标识(Group Radio Network Temporary Identifier，g-RNTI)和是否进行混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈等。其中，可以是每个TMGI业务对应一套生效区域信息和/或支持的小区信息，或 者是一组TMGI业务对应一套生效区域信息和/或支持的小区信息。
应理解，对于idle态和inactive状态的终端来说，由于它们的移动性是自己控制的，因此需要在移动过程中重选小区时，自行考虑目标小区的选择，以便于MBS业务接收的连续性。
可选的，网络设备可以为终端配置小区重选条件，也可以由协议约定小区重选条件。在满足该重选条件后，可以由终端基于上述MBS业务的相关信息选择重选的目标小区。例如，在终端满足同频或者异频邻小区测量之后，终端开始检测链路质量，当满足小区重选条件时，终端优先选择邻小区里与当前感兴趣业务在同一个生效区域的小区，或者支持该感兴趣业务的小区。
终端重选了一个目标小区后，如果该目标小区与原小区的MBS业务配置属于同一个区域，则终端在原小区获得的MBS业务的第一配置信息可以直接使用，终端直接使用该第一配置信息进行MBS业务接收。如果该目标小区仅仅是支持相同MBS业务的小区，则第一配置信息可能不同，终端要在该小区重新获得MBS业务配置。获得业务配置的方式为重新读取广播消息中携带的MBS业务的第二配置信息，或者重新进入连接态，以专用信令方式获得MBS业务配置。
可选的，处于连接态的终端利用专用信令方式获得了MBS业务的第二配置信息和MBS业务的相关信息之后，也可能释放连接，回到idle态或者inactive状态。
本发明实施例中，通过在所述终端处于空闲态或者非激活态接收MBS业务、且满足小区重选条件的情况下，根据所述MBS业务的相关信息确定重选的目标小区；基于所述目标小区接收所述MBS业务。由于基于所述MBS业务的相关信息确定重选的目标小区，这样，可以在基于满足重选准则的邻小区中，优先选择第一配置信息的生效的邻小区或支持所述MBS业务的邻小区，从而保证MBS业务接收的连续性。
可选的，所述基于所述目标小区接收所述MBS业务包括以下任一项：
在所述原小区对应的区域与所述目标小区对应的区域相同的情况下，根据所述第一配置信息在所述目标小区接收所述MBS业务；
在所述原小区对应的区域与所述目标小区对应的区域不相同的情况下， 根据所述目标小区发送的第二配置信息，在所述目标小区接收所述MBS业务。
一实施例中，上述原小区对应的区域与所述目标小区对应的区域相同可以理解为：MBS业务的第一配置信息在原小区和目标小区均生效。换句话说，目标小区和原小区对于同一MBS业务的配置信息相同。
另一实施例中，在所述原小区对应的区域与所述目标小区对应的区域不相同可以理解为：原小区的第一配置信息在目标小区不能继续使用。具体的，可以通过区域标识表示小区所在的区域是否相同，本实施例中，原小区的区域标识与目标小区的区域标识不同。需要说明的是，目标小区不一定支持该MBS业务，即由区域不同并不能直接推导出支持不同配置的该MBS业务。只有在目标小区支持该MBS业务的情况下，可以获取到目标小区针对该MBS业务发送的第二配置信息，并根据该第二配置信息接收MBS业务。
应理解，本实施例中，在目标小区上接收MBS业务之前，还可以基于相关信息，确定目标小区对应的区域与所述目标小区对应的区域是否相同。也就是说：在基于所述目标小区接收所述MBS业务之前，所述方法还包括以下任一项：
在所述相关信息包括所述生效区域信息的情况下，根据所述生效区域信息确定所述原小区对应的区域与所述目标小区对应的区域相同或不同；
在所述相关信息不包括所述生效区域信息或者不包括所述相关信息的情况下，确定所述原小区对应的区域与所述目标小区对应的区域不同。
本实施例中，可以在选择重选的目标小区时，确定目标小区时，即可确定目标小区对应的区域与所述目标小区对应的区域是否相同。
需要说明的是，网络设备对生效区域信息和支持MBS业务的小区信息的指示方式可以根据实际需要进行设置，
例如，在一实施例中，所述相关信息包括所述生效区域信息的情况下，所述生效区域信息包括：第一小区标识列表或区域标识；
其中，所述第一配置信息在所述第一小区标识列表包含的小区中生效，所述第一配置信息在与所述区域标识相同的小区中生效。
在一实施例中，所述相关信息包括所述支持所述MBS业务的小区信息的情况下，所述支持所述MBS业务的小区信息包括第二小区标识列表，所述第 二小区标识列表包含的小区均支持所述MBS业务的传输。
针对上述第一小区标识列表，可以理解为给出了某组MBS业务信息在哪些小区仍旧能够使用；针对上述第二小区标识列表，可以理解为给出MBS业务在哪些小区仍旧能够支持传输；其中两者的区别是，生效区域信息，代表该小区支持这个业务且配置与本小区完全相同，UE可以不用读取配置信息，直接接收MBS业务，而支持的小区列表信息，指该MBS业务在那个小区也进行发送，但配置不一定相同，UE需要重新读取配置信息，从而才能够接收MBS业务。
区域标识，区域标识也用于定义生效的范围，凡是在邻小区有相同的区域标识广播，则认为MBS业务的第一配置信息在那些小区也可以使用。在其他实施例中，区域标识也可以用以区分支持相同业务但是不同配置的小区标识。
需要说明的是，上述MBS业务包括N个业务，N为正整数。对于相关信息包括的内容不同，重选的目标小区时，选择的目标小区不同，以下针对不同情况对重选目标小区的具体实现进行详细说明。
情况1，所述相关信息仅包括所述支持所述MBS业务的小区信息情况下，所述根据所述MBS业务的相关信息确定重选的目标小区包括：
按照业务优先级从高到低的顺序依次遍历所述N个业务，直到确定目标小区；其中，在当前遍历的第二业务满足第二预设条件的情况下，所述目标小区根据第二邻小区确定；所述第二预设条件包括：满足重选需求的L个邻小区中包括支持所述第二业务的邻小区；
所述第二邻小区为所述L个邻小区中，支持所述第二业务的邻小区。
本实施例中，满足重选需求可以理解为满足重选准则，终端在获得感兴趣的MBS业务的第一配置信息同时，获得了邻小区支持该业务的信息，例如针对MBS业务TMGI 1在邻小区中，有cell3和cell4支持该业务；在这种情况下，由于没有携带MBS业务配置的生效区域，意味着默认MBS业务配置仅在本小区生效，因此终端一旦移出了当前小区，重选到目标小区之后，MBS业务配置需要立即释放，不能继续使用。
当终端在判断重选的目标小区时，如果有小区cell3和cell6同时满足小 区重选要求，则优先选择cell3进行接入，因为cell3可以支持终端感兴趣的MBS业务。
当终端重选到cell3之后，需要立即释放原来的MBS业务配置，重新获得感兴趣的MBS业务配置，获得的方式可以是从广播信令里读取，也可以是进入连接态，向网络请求专用信令方式发送。
需要特殊说明的是，当终端感兴趣的MBS业务不止一个，而在小区重选时，没有一个目标小区能支持全部的感兴趣MBS业务，那此时如何重选，由终端自行实现决定。例如终端感兴趣MBS TMGI1邻小区cell3和cell4支持，感兴趣MBS TMGI2在邻小区cell6和cell7支持，此时如果重选小区时，cell3和cell6满足小区重选要求，则此时是要重选到cell3接收业务TMGI 1，还是重选到cell6接收业务TMGI 2，由终端自己根据业务优先级进行决定。
例如，在一实施例中，首先可以确定满足小区重选要求的邻小区，然后按照业务优先级从高到低的方式遍历每一业务，判断满足小区重选要求的邻小区中是否包括支持当前遍历的业务的小区。若有，则退出遍历，并根据满足小区重选要求的邻小区中当前遍历的业务的小区确定目标小区；若没有，则继续遍历下一优先级的业务。当满足小区重选要求的邻小区都不支持N个业务中的任一业务时，可以基于邻小区的测量结果确定目标小区。
在另一实施例中，也可以首先按照业务优先级从高到低的方式遍历每一业务，然后判断支持当前遍历的业务的小区中是否有满足小区重选要求的邻小区。若有则退出遍历，并根据支持当前遍历的业务的小区中满足小区重选要求的邻小区确定目标小区。
情况2，所述相关信息仅包括所述生效区域信息情况下，所述根据所述MBS业务的相关信息确定重选的目标小区包括：
按照业务优先级从高到低的顺序依次遍历N个业务，直到确定目标小区；其中，在当前遍历的第一业务满足第一预设条件的情况下，所述目标小区根据第一邻小区确定，所述第一预设条件包括：满足重选需求的L个邻小区中包括所述第一业务的第一配置信息生效的邻小区；
所述第一邻小区为所述L个邻小区中，所述第一业务的第一配置信息生效的邻小区。
终端在获得感兴趣的MBS业务配置同时，获得了配置生效区域信息，例如针对MBS业务TMGI 1的配置，其生效区域为10，或者明确列出该区域包含有cell3和cell4以相同配置支持该业务传输；则终端在即将重选的目标小区为区域10范围内的小区时，例如cell3或者cell4，则终端不需要重新读取MBS业务配置信息，直接可以以当前的配置信息进行业务接收。
当终端在判断重选的目标小区时，如果有小区cell3和cell6同时满足小区重选要求，则优先选择cell3进行接入，因为cell3属于相同的区域。
当终端重选到相同区域之外的小区之后，需要立即释放原来的MBS业务配置，重新获得感兴趣的MBS业务配置，获得的方式可以是从广播信令里读取，也可以是进入连接态，向网络请求专用信令方式发送。
特别的，当感兴趣的业务不止一个，而又属于不同的区域时，此时如何进行重选小区的选择，由终端自行根据业务优先级决定。相同区域的业务配置可以直接使用，不同区域的业务配置需要重新获取。
情况3，所述相关信息包括所述生效区域信息和所述支持所述MBS业务的小区信息情况下，所述根据所述MBS业务的相关信息确定重选的目标小区包括：
按照业务优先级从高到低的顺序依次遍历所述N个业务，直到确定目标小区；其中，在当前遍历的第三业务满足第三预设条件的情况下，所述目标小区根据第三邻小区确定；在当前遍历的第三业务不满足第三预设条件，且满足第四预设条件的情况下的情况下，所述目标小区根据第四邻小区确定；
所述第三预设条件包括：满足重选需求的L个邻小区中包括所述第三业务的第一配置信息生效的邻小区；
所述第四预设条件包括：满足重选需求的L个邻小区中包括支持所述第三业务的邻小区；
所述第三邻小区为所述L个邻小区中，所述第三业务的第一配置信息生效的邻小区；
所述第四邻小区为所述L个邻小区中，支持所述第三业务的邻小区。
本实施例中，终端在获得感兴趣的MBS业务配置同时，既有配置生效区域信息，也有邻小区支持信息，则终端按照自己业务优先级，优先考虑保证 最高优先级业务的连续接收。例如先考虑最高优先级业务能够配置区域一致的小区，其次是最高优先级业务能够支持的其它小区，然后是其它优先级业务的区域一致的小区或者支持其它优先级业务的小区。
为了更好的理解本发明的实现，以下对本发明的具体实现进行详细说明。
一、网络设备向终端发送多播配置信息。
终端从当前服务小区，获得关于感兴趣的多播业务配置信息，同时获得该配置信息的生效区域信息，或者支持相同业务的小区信息等。其中多播业务配置信息包括：TMGI、业务周期、DRX信息、业务配置信息、业务调度和传输信息等。
这些配置信息的生效区域信息和支持相同业务的小区信息，可以包括如下方式：
方式1：小区列表信息，给出这组MBS业务信息在哪些小区仍旧能够使用，给出具体的小区标识列表(id list)；或者给出MBS业务在哪些小区仍旧能够支持传输，给出具体的小区id list；其中两者的区别是，生效区域信息，代表该小区支持这个业务且配置与本小区完全相同，终端可以不用读取配置信息，直接接收MBS业务，而支持的小区列表信息，指该MBS业务在那个小区也进行发送，但配置不一定相同，终端需要重新读取配置信息，从而才能够接收MBS业务。
方式2：区域标识，区域标识也用于定义生效的范围，凡是在邻小区有相同的区域标识广播，则认为MBS业务信息在那些小区也可以使用；区域标识也可以用以区分支持相同业务但是不同配置的小区标识。
方式3：仅本小区生效，是一种默认方式，例如任何额外区域信息都不带，则说明这些配置信息只在本小区生效，一旦终端移出了本小区范围，则配置信息失效。
终端从当前服务小区获得感兴趣多播配置信息及生效区域信息、支持的小区信息的方式，可以是通过广播信令，也可以通过专用信令。广播信令可以应用于idle态终端，inactive终端和连接态终端。而专用信令则仅适用于当前处于连接态的终端。
处于连接态的终端利用专用信令方式获得了多播配置信息和生效区域信 息之后，也可能释放连接，回到idle态或者inactive状态。
信令的方式，可以是每个TMGI业务对应一套生效区域信息、支持的小区信息，或者是一组TMGI业务对应一套生效区域信息、支持的小区信息。
对于连接态的终端，由于他的移动性是完全由网络侧控制的，网络侧通过他感兴趣的业务信息匹配邻小区支持感兴趣业务信息情况，可以合理的为终端选择目标小区。因此这些区域信息和支持的小区信息主要用于终端自主移动时的目标小区选择。
二、终端移动到同区域小区。
对于idle态和inactive状态的终端来说，由于它们的移动性是自己控制的，因此需要在移动过程中重选小区时，自行考虑目标小区的选择，以便于MBS业务接收的连续性。
由于终端已经在本小区获得了MBS业务配置信息和生效区域信息、支持小区信息，因此对终端来说，需要根据生效区域信息、支持的小区信息，优先选择可以持续接收MBS业务的小区，具体如下：
在终端满足同频或者异频邻小区测量之后，终端开始检测链路质量，当满足小区重选条件时，终端优先选择邻小区里与当前感兴趣业务在同一个生效区域的小区，或者支持该感兴趣业务的小区；
由于小区重选的优先级是基于频点来设置的，因此MBS业务尽量在一个频点上进行发送，idle/inactive终端将该频点设置为高优先级的频点，有利于终端尽量驻留在该频点进行MBS业务接收；
终端重选了一个小区，如果该小区与原来小区的MBS业务配置属于同一个区域，则终端在原小区获得的MBS业务配置，可以直接使用，终端直接使用该配置进行MBS业务接收。如果该小区仅仅是支持相同MBS业务的小区，则配置可能不同，终端需要在该小区重新获得MBS业务配置。获得业务配置的方式为重新读取广播消息中携带的MBS业务配置，或者重新进入连接态，以专用信令方式获得MBS业务配置。
三、终端移动到区域边缘。
如果终端即将重选的小区，不属于MBS业务配置的生效区域，具体的该小区SIB中广播的区域ID与业务配置时通知的区域ID不同，证明是不同区 域。这时候终端存储的MBS业务配置马上失效，一旦发生了重选，则需要释放该配置。终端在不同的区域，也需要重新获得MBS业务配置。获得业务配置的方式为重新读取广播消息中携带的MBS业务配置，或者重新进入连接态，以专用信令方式获得MBS业务配置，在获得配置的同时，也有区域信息或者邻小区是否支持信息，便于终端进行下次小区重选。
如果终端在该小区无法获得MBS相关的业务配置，或者终端感兴趣的业务在该小区不支持，则终端需要建立单播，进行相关业务的传输，这个单播是指从核心网侧到RAN侧到终端都是单播传输，维护协议数据单元会话(Protocol Data Unit session，PDU session)。
终端如果发现即将移动到的目标小区，属于不支持感兴趣业务的小区，则可以提前进行单播建立请求，以降低时延和业务中断。
四、终端的各种移动场景。
本实施例给出在各种不同的配置之下，终端如何进行移动。
首先，前提是终端在当前小区获得了自己感兴趣的MBS业务的配置，可以是通过广播信令获得，也可以是通过专用信令获得，在本小区可以顺利的接收MBS业务。
其次，当终端移动到本小区覆盖边缘，需要进行小区重选时，各种情况：
第一种情况，终端在获得感兴趣的MBS业务配置同时，获得了邻小区支持该业务的信息，例如针对MBS业务TMGI 1在邻小区中，有cell3和cell4支持该业务；在这种情况下，由于没有携带MBS业务配置的生效区域，意味着默认MBS业务配置仅在本小区生效，因此终端一旦移出了当前小区，重选到目标小区之后，MBS业务配置需要立即释放，不能继续使用。
当终端在判断重选的目标小区时，如果有小区cell3和cell6同时满足小区重选的要求，则优先选择cell3进行接入，因为cell3可以支持终端感兴趣的MBS业务。
当终端重选到cell3之后，需要立即释放原来的MBS业务配置，重新获得感兴趣的MBS业务配置，获得的方式可以是从广播信令里读取，也可以是进入连接态，向网络请求专用信令方式发送。
需要特殊说明的是，当终端感兴趣的MBS业务不止一个，而在小区重选 时，没有一个目标小区能支持全部的感兴趣MBS业务，那此时如何重选，由终端自行实现决定。例如终端感兴趣MBS TMGI1邻小区cell3和cell4支持，感兴趣MBS TMGI2在邻小区cell6和cell7支持，此时如果重选小区时，cell3和cell6满足小区重选的要求，则此时是要重选到cell3接收业务TMGI 1，还是重选到cell6接收业务TMGI 2，由终端自己根据业务优先级进行决定。
第二种情况，终端在获得感兴趣的MBS业务配置同时，获得了配置生效区域信息，例如针对MBS业务TMGI 1的配置，其生效区域为10，或者明确列出该区域包含有cell3和cell4以相同配置支持该业务传输；则终端在即将重选的目标小区为区域10范围内的小区时，例如cell3或者cell4，则终端不需要重新读取MBS业务配置信息，直接可以以当前的配置信息进行业务接收。
当终端在判断重选的目标小区时，如果有小区cell3和cell6同时满足小区重选的要求，则优先选择cell3进行接入，因为cell3属于相同的区域。
当终端重选到相同区域之外的小区之后，需要立即释放原来的MBS业务配置，重新获得感兴趣的MBS业务配置，获得的方式可以是从广播信令里读取，也可以是进入连接态，向网络请求专用信令方式发送。
特别的，当感兴趣的业务不止一个，而又属于不同的区域时，此时如何进行重选小区的选择，由终端自行根据业务优先级决定。相同区域的业务配置可以直接使用，不同区域的业务配置需要重新获取。
第三种情况，终端在获得感兴趣的MBS业务配置同时，既有配置生效区域信息也有邻小区支持信息，则终端按照自己业务优先级，优先考虑保证最高优先级业务的连续接收。例如先考虑最高优先级业务能够配置区域一致的小区，其次是最高优先级业务能够支持的其它小区，然后是其它业务的区域一致或者其它支持小区。
总体来说，为了保证idle或inactive终端在移动时对MBS业务接收的连续性，尽量将MBS业务放在一个频点发送，可以使终端将该频点设置为小区重选最高优先级，便于终端在上面连续接收。在此基础上还可以设置区域生效信息，用于不同的小区支持相同的MBS业务配置，或者邻小区支持该业务的信息，便于终端重选挑选小区。
MBS频点是一个较大的范围，支持该业务的邻小区范围小了一些，配置相同的区域这个范围最小。其中，支持MBS业务的邻小区可以理解为不同小区以不同的配置支持MBS业务传输，配置相同的区域可以理解为小区通过Xn接口交互关于MBS业务配置以保持一致。
