具体实施方式
本发明实施列提供一种管控MBMS业务广播区域的方法、基站及存储介质，以解决现有技术中存在的5G MBMS业务不够灵活、不能动态变化的技术问题。
本申请实施例中的技术方案为解决上述的技术问题，总体思路如下：
提供一种管控MBMS业务广播区域的方法，应用于基站，该方法包括：在由单频网SFN对齐的多个MBMS传输小区构成的同步区域内，广播有效区域信息；其中，有效区域信息用于指示同步区域内传输相同MBMS业务的有效区域的范围。
由于在上述方案中，通过在由多个单频网SFN对齐的MBMS传输小区构成的同步区域内，广播有效区域信息；其中，有效区域信息用于指示同步区域内传输相同MBMS业务的有效区域的范围，从而可以允许5G接入网节点在MBMS业务准备或传输期间对有效区域的范围进行动态变更，这样就能够满足5G MBMS业务的灵活传输，动态改变不同的业务传输模式，进一步节省网络资源，改善用户体验。
为了更好的理解上述技术方案，下面通过附图以及具体实施例对本发明技术方案做详细的说明，应当理解本发明实施例以及实施例中的具体特征是对本发明技术方案的详细的说明，而不是对本发明技术方案的限定，在不冲突的情况下，本发明实施例以及实施例中的技术特征可以相互组合。
本发明实施例提供一种管控MBMS业务广播区域的方法，应用于基站， 该方法的处理过程如下。
在由SFN对齐的多个MBMS传输小区构成的同步区域内，广播有效区域信息；其中，有效区域信息用于指示同步区域内传输相同MBMS业务的有效区域的范围。
例如，同步区域中包括MBMS传输小区1～30，其中MBMS业务1在MBMS传输小区8～15中同步传输，MBMS业务1对应的有效区域为MBMS传输小区8～15，记为有效区域1；MBMS业务2～5在MBMS传输小区20～28中同步传输，MBMS业务2～5对应的有效区域为MBMS传输小区20～28，记为有效区域2，根据有效区域1生成有效区域信息1，根据有效区域2生成有效区域信息2，基站在同步区域内广播有效区域信息1、有效区域信息2便可让同步区域中的终端确定MBMS业务1～5在哪些小区中能够接收到。
在本发明提供的实施例中，有效区域信息包括小区标识和/或至少一个临时移动组标识TMGI；其中，TMGI与MBMS业务一一对应。
小区标识包括PCI列表或CGI列表。
当TMGI为多个时，可以TMGI小组(per TMGI group)的方式存在于有效区域信息中。
在本发明提供的实施例中，有效区域中的小区与至少一个有效区域信息对应。也就是说有效区域中的小区允许配置一个或多个有效区域信息。
在本发明提供的实施例中，在有效区域内传输的SC-MCCH消息中还包括有效区域内每个MBMS会话对应的有效区域编码信息；其中，一个有效区域对应一个有效区域编码。用户终端在接收到该SC-MCCH消息后，将从中获取的每个MBMS会话对应的有效区域编码信息(也可以理解为MBMS会话与有效区域编码信息的对应关系)存储在本地。
其中，每个MBMS会话对应一个或多个有效区域编码信息。基站允许变更MBMS会话与有效区域编码信息的对应关系。
在指定的系统消息中还包括同步区域内各小区中MBMS业务对应的有效区域编码信息。这使得用户终端从当前驻留小区对应的指定的系统消息中获 取有效区域编码信息中的第二有效区域编码后，针对一个MBMS业务(例如这个业务是用户终端正在接收的MBMS业务)，用户终端将从指定的系统消息中获取的第二有效区域编码与本地存储的(即从SC-MCCH消息中获取的)第一有效区域编码进行比较，若相同则继续接收该MBMS业务，否则确定当前驻留小区不在MBMS业务的有效区域范围内。
广播有效区域信息，有以下两种方式：
第一种方式，有效区域信息携带在指定的系统消息中广播，例如有效区域对应的是MBMS业务1，则有效区域信息携带在MBMS业务1的系统信息(System Information Block，SIB)消息进行广播。
第二种方式，有效区域信息携带在SC-MCCH消息中广播，例如，有效区域信息通过各小区的SC-MCCH信道发送给用户终端，则该有效区域信息便可携带在SC-MCCH消息中。
当有效区域的范围发生变化时，根据变化后的有效区域的范围，更新有效区域信息。
例如，有效区域包括的小区为小区1～小区5，当小区6加入该有效区域后，确定该有效区域的范围发生了变化，此时需要根据变化后的有效区域的范围更新有效区域信息。
更新有效区域信息，相应的也有两种方式：
第一种，变化后的有效区域信息携带在指定的系统更新消息中发送给用户终端，使用户终端根据变化后的有效区域信息更新有效区域信息；其中，变化后的有效区域信息是根据变化后的有效区域的范围确定的。
例如，有效区域包括的小区为小区1～小区5，当小区6加入该有效区域后，确定该有效区域的范围发生了变化，此时需要根据变化后的有效区域的范围生成变化后的有效区域信息，将该变化后的有效区域信息携带在对应MBMS SIB更新消息中发送给用户终端，让用户终端根据变化后的有效区域信息更新有效区域信息。
第二种方式，变化后的有效区域信息携带在SC-MCCH更新消息中发送 给用户终端，使所述用户终端根据所述变化后的有效区域信息更新所述有效区域信息。
例如，有效区域包括的小区为小区1～小区5，当小区6加入该有效区域后，确定该有效区域的范围发生了变化，此时需要根据变化后的有效区域的范围生成变化后的有效区域信息，将该变化后的有效区域信息携带在对应SC-MCCH更新消息中发送给用户终端，让用户终端根据变化后的有效区域信息更新有效区域信息。
在从基站侧介绍完了管控MBMS业务广播区域的方法后，下面将从用户终端侧进行介绍。
为管控MBMS业务广播区域的方法在用户终端侧的实施过程。
接收基站广播的有效区域信息；其中，有效区域信息用于指示同步区域内传输相同MBMS业务的有效区域的范围，同步区域包括多个单频网SFN对齐的MBMS传输小区。
在本发明提供的实施例中，有效区域信息包括小区标识和/或至少一个TMGI；其中，TMGI与MBMS业务一一对应。
小区标识包括PCI列表或CGI列表。
当TMGI为多个时，可以per TMGI group的方式存在于有效区域信息中。
在本发明提供的实施例中，有效区域中的小区与至少一个有效区域信息对应。也就是说有效区域中的小区允许配置一个或多个有效区域信息。
接收基站广播的有效区域信息，有以下几种方式：
第一种方式，通过指定的系统消息接收有效区域信息；若有效域的范围发生变化，通过指定的系统更新消息接收变化后的有效区域信息，以更新有效区域信息；其中，变化后的有效区域信是根据变化后的有效区域的范围确定的。
例如，同步区域中包括MBMS传输小区1～20，其中MBMS业务在MBMS传输小区6～12中同步传输，该MBMS业务对应的有效区域为MBMS传输小区6～12，基站根据该有效区域生成有效区域信息，并通过SIB消息发送给用 户终端，用户终端从SC-MCCH消息中获取有效区域信息，并存储在本地。
当上述有效区域的范围发生了变化，如小区18新加入了该有效区域，此时确定变化后的有效区域的范围为小区6～12以及小区18，基站根据变化后的有效区域的范围生成对应的变化后的有效区域信息，并通过SIB更新消息发送给用户终端，用户终端从该SIB更新消息中获取变化后的有效区域信息，利用变化后的有效区域信息更新之前的有效区域信息。第二种方式，通过SC-MCCH消息接收有效区域信息，若所述有效域信息发生变化，通过SC-MCCH更新消息接收所述变化后的有效区域信息，以更新有效区域信息。
例如，同步区域中包括MBMS传输小区12～50，其中MBMS业务在MBMS传输小区12～40中同步传输，该MBMS业务对应的有效区域为MBMS传输小区12～40，基站根据该有效区域生成有效区域信息，并通过SC-MCCH消息发送给用户终端，用户终端从SC-MCCH消息中获取有效区域信息，并存储在本地。
当上述有效区域的范围发生了变化，如小区20和26从该有效区域中去除，此时确定变化后的有效区域的范围为小区12～19以及小区21～25和27～40，基站根据变化后的有效区域的范围生成对应的变化后的有效区域信息，并通过SC-MCCH更新消息发送给用户终端，用户终端从该SC-MCCH更新消息中获取变化后的有效区域信息，利用变化后的有效区域信息更新之前的有效区域信息。
不同MBMS业务的数据在传输的过程中，通常都会采用不同的编码方式对数据进行编码后再进行传输，相应的用户终端要获得MBMS业务的数据采用的何种编码方式后才能对编码后的MBMS业务的数据进行解析，进而获取MBMS业务的数据。
在本发明提供的实施例中，用户终端可以从SC-MCCH消息中获取有效区域内每个MBMS会话对应的有效区域编码信息；其中，一个有效区域对应一个有效区域编码，并将每个MBMS会话对应的有效区域编码信息存储在本地。
例如，用户终端在当前驻留小区(假设为小区1)接收到SC-MCCH消息后，从中获取每个MBMS会话对应的有效区域编码信息，并存储在本地。
在本发明提供的实施例中，用户终端还可以从当前驻留小区接收指定的系统消息；其中，指定的系统消息中包括当前驻留小区的MBMS业务对应的有效区域编码信息；针对一个MBMS业务，判断本地存储的与该一个MBMS业务关联的第一有效区域编码与从指定的系统消息中获取的第二有效区域编码是否相同，若相同则继续接收该一个MBMS业务。这样就能让用户终端在有效区域内不重复读取相应的SC-MCCH信道，从而可以连续接收相应的MBMS会话数据。
其中，每个MBMS会话对应一个或多个有效区域编码信息。基站允许变更MBMS会话与有效区域编码信息的对应关系。
若第一有效区域编码与第二有效区域编码不同，则确定用户终端当前驻留的小区不在该一个MBMS业务对应的有效区域的范围内。用户终端可以根据自身需求向基站发起接收该一个MBMS业务的请求。
例如，MBMS业务1～MBMS业务6对应有效区域1，基站根据有效区域1生成相应的有效区域编码信息1，在该有效区域编码信息中包括MBMS业务1～MBMS业务6对应的每个MBMS会话对应的有效区域编码，并将每个MBMS会话对应的有效区域编码通过SC-MCCH消息发送给用户终端，用户从中获取每个MBMS会话对应的有效区域编码并存储在本地。
假设用户终端当前正在接收MBMS业务2，其对应的有效区域编码为有效区域编码1，用户终端从小区1移动到小区2后，从小区2对应的SIB消息中获取MBMS业务2对应的有效区域编码1，用户终端比较本地存储的与MBMS业务2对应的第一有效区域编码1与从小区2对应的SIB消息中获取的第二有效区域编码1相同，确定用户终端当前驻留的小区(即小区2)在有效区域1的范围内。
又如，当用户终端从小区2移动到小区8后，从当前驻留的小区8对应的SIB消息中获取MBMS业务2对应的有效区域编码信息，从中获取到有效 区域编码2，用户终端将有效区域编码2与本地存储的与MBMS业务2对应的有效区域编码1进行比较，比较结果为不相同，用户终端在当前驻留的小区8不再MBMS业务2的有效区域内。
在从基站侧(即网络侧)和终端侧分别介绍了管控MBMS业务广播区域的方法后，为便于本领域的技术人员能充分理解上述技术方案，下面将提供几个实施例进行介绍。
实施例一、通过指定的系统消息广播有效区域信息。
请参见图1为本发明实施例提供的采用指定的系统消息广播有效区域信息的流程图。
步骤101：基站确定MBMS业务的有效区域，并生成相应的有效区域信息，将有效区域信息携带在MBMS SIB消息中。
基站可以通过业务统计，或无线资源管理(Radio Resource Management，RRM)策略等，或基于接收的MBMS会话消息等，确定某些MBMS业务进行多小区广播所对应的有效区域，进而根据该有效区域生成对应的有效区域信息。此有效区域信息包含有PCI列表(PCI list)或CGI列表(CGI list)。
在本实施例中，指定的系统消息为MBMS SIB消息。
需要说明的是，MBMS业务可能是一个MBMS业务，也可能是多个MBMS业务，也就是说在一个有效区域内可能同时传输一个MBMS业务，也可能同时传输多个MBMS业务，具体不做限定。
步骤102：基站广播MBMS SIB消息。
当指定的系统消息为MBMS SIB消息时，基站通过各小区的广播控制信道(Broadcast Control Channel，BCCH)广播MBMS SIB消息。

准备接收该MBMS业务的用户终端无论是处于空闲态(Idle)或是连接态(connected)，在接收到该MBMS SIB消息后，将在有效区域信息对应的有效区域内，不再重复读取相应的SC-MCCH信道，从而可以实现连续接收相应的MBMS会话数据。

基站通过业务统计，或RRM策略等，或基于接收的MBMS会话更新消息等，确定需要改变某些MBMS业务的有效区域，例如动态增加或减少该有 效区域内的MBMS小区，于是生成相应的变化后的有效区域信息，并将该变化后的有效区域信息携带在MBMS SIB变更消息中。
步骤302：基站发送MBMS SIB变更消息。

实施例四、通过SC-MCCH变更消息变更有效区域信息。
请参见图4为本发明实施例提供的采用指定的系统更新消息变更有效区域信息的流程图。
步骤401：基站确定MBMS业务的有效区域发送变化后，生成相应的变化后的有效区域信息，将变化后的有效区域信息携带在SC-MCCH变更消息中。
基站通过业务统计，或RRM策略等，或基于接收的MBMS会话更新消息等，确定需要改变某些MBMS业务的有效区域，例如动态增加或减少该有效区域内的MBMS小区，于是生成相应的变化后的有效区域信息，并将该变化后的有效区域信息携带在SC-MCCH变更消息中。
步骤402：基站发送SC-MCCH变更消息。
基站通过MBMS特定的通知方式通知用户终端相应的SC-MCCH消息发生变更，并在该SC-MCCH消息的修改周期边界发送给用户终端。
步骤403：用户终端接收SC-MCCH变更消息，并从中获取变化后的有效区域信息，以便对有效区域信息进行变更。
准备接收该MBMS业务的用户终端无论是处于空闲态(Idle)或是连接态(connected)，在接收到该SC-MCCH变更消息后，将在变化后的有效区域信息对应的变化后的有效区域内，不再重复读取相应的SC-MCCH信道，从而可以实现连续接收相应的MBMS会话数据。
由于基站的集中单元(Centralized Unit，CU)与分布单元(Distributed Unit，DU)可以进行分离部署，所以下面将介绍CU与DU分离部署时管控MBMS业务广播区域的过程。
实施例五、基站采用CU/DU分离部署的方式管理有效区域的方案一。
请参见图5为本发明实施例提供的基站中的CU与DU分离部署时管理有效区域的流程图一。
步骤501：CU与DU交互MBMS业务对应的有效区域信息或变化后的有效区域信息。
基站中的CU与DU通过F1公用接口消息交互MBMS业务进行多小区广播的有效区域信息或者变化后的有效区域信息。
有效区域信息或者变化后的有效区域信息中包括PCI list或CGI list。
有效区域信息或者变化后的有效区域信息，可以F1平均正确率(Average Precision，AP)IE的方式包含在公用接口消息里，也可以采用无线资源控制容器(Radio Resource Control Container，RRC container)形式包含在公用接口消息里，例如：以MBMS专有的SIB消息(SIB message)形式传送给DU。
步骤502：CU与DU交互MBMS业务对应的调度和会话的相关信息。

实施例七、基站管理有效区域对应的有效区域编码。
请参见图7为本发明实施例提供的传输有效区域对应的有效区域编码信息的流程图。
步骤701：基站确定MBMS业务的有效区域，并生成相应的有效区域编码信息，将MBMS业务的MBMS会话与有效区域编码信息的映射关系携带在SC-MCCH消息中。
基站通过业务统计，或RRM策略等，或基于接收的MBMS会话消息等，确定某些MBMS业务的进行多小区广播的有效区域，并相应生成对应的有效 区域编码信息。其中，一个或多个MBMS会话对应同一个有效区域编码信息，或，每个MBMS会话对应一个或多个有效区域编码信息。
一个有效区域内可以对应一个MBMS业务，也可以对应多个MBMS业务。
步骤702：基站发送SC-MCCH消息。
步骤703：用户终端接收SC-MCCH消息，从中获取并保存MBMS会话与有效区域编码信息的映射关系。
假设用户终端当前驻留小区为小区1，用户终端在小区1中接收到SC-MCCH消息，并从中获取MBMS会话与有效区域编码信息的映射关系，存储在本地。
通常是多个MBMS会话各自对应的有效区域编码，这些MBMS会话中可能有一些MBMS会话对应的有效区域编码是相同，也可能全不同。
步骤704：基站生成有效区域内各小区对应的MBMS业务的有效区域编码信息，将该有效区域编码信息携带在SIB消息中。
由于有效区域内的小区还可能属于其它有效区域，所以基站会生成各小区对应的MBMS业务的有效区域编码信息，并携带在对应的SIB消息中通过BCCH信道发送给用户终端。
步骤705：基站发送SIB消息。
基站通过相应小区的BCCH信道发送对应的SIB消息。
步骤706：用户终端接收SIB消息，并从中获取有效区域编码信息，比较从SIB消息中获取的有效编码信息与本地保存的有效编码是否相同，根据比较结果对MBMS业务进行处理。
准备接收某个MBMS会话(假设对应MBMS业务1)的用户终端通过解读当前驻留小区与MBMS相关的SIB消息后，获取相应的有效区域编码信息，并比较从SIB消息中获取的第二有效区域编码与存储在本地的MBMS业务1关联的第一有效区域编码是否相同，从而对MBMS业务1采取不同的处理行为。即，若相同，则继续接收MBMS业务1。否则，确定当前驻留小区不在 MBMS业务1的同步区域内，用户终端可以根据自身需求决定是否向网络侧重新发起MBMS业务1的接收请求。
实施例八、基站采用CU/DU分离部署的方式管理有效区域的有效区域编码。
请参见图8为本发明实施例提供的基站中的CU与DU分离部署时管理有效区域的流程图。
步骤801：CU确定MBMS业务的有效区域，并生成相应的有效区域编码信息，将MBMS业务的MBMS会话与有效区域编码信息的映射关系携带在SC-MCCH消息中。
CU通过业务统计，或RRM策略等，或基于接收的MBMS会话消息等，确定某些MBMS业务进行多小区广播的有效区域，并相应生成对应的有效区域编码信息。其中，允许一个或多个MBMS会话对应同一个有效区域编码信息，还可以是每个MBMS会话对应一个或多个有效区域编码信息；CU生成相应的SC-MCCH消息，该SC-MCCH消息中包含MBMS会话与相应有效区域编码信息的映射关系。
步骤802：CU与DU交互某些MBMS业务对应的有效区域信息或变化后的相关信息，该相关信息中包括MBMS会话与有效区域编码信息的映射关系。

步骤803：DU发送MCCH的配置信息，该MCCH的配置信息中包括MBMS会话与有效区域编码信息的映射关系。
DU通过相应小区的SC-MCCH信道发送多小区MCCH的配置信息给用户设备(User Equipment，UE)。
步骤804：用户终端接收SC-MCCH消息，从中获取并保存MBMS会话与有效区域编码信息的映射关系。
假设用户终端当前驻留小区为小区1，用户终端在小区1接收到 SC-MCCH消息，并将从中获取的MBMS会话与有效区域编码信息的映射关系存储在本地。也就是说用户终端在小区1获得了多个MBMS会话各自对应的有效区域编码信息，这些MBMS会话与相应MBMS业务对应。
步骤805：DU生成或获取MBMS相关的SIB消息，在该SIB消息中包括对应的有效区域编码信息。
步骤806：DU发送SIB消息。
上述SIB信息通过小区的BCCH信道发送给用户终端。
步骤807：用户终端接收SIB消息，并从中获取有效区域编码信息，比较从SIB消息中获取的有效编码信息与本地保存的有效编码是否相同，根据比较结果对MBMS业务进行处理。
