Description

MBSFN区域的小区管理方法、装置和计算机存储介质 技术领域
本发明涉及通信领域中的信息传输技术，尤其涉及一种MBSFN区域的小区管理方法、装置和计算机存储介质。
背景技术
目前，增强多媒体广播和组播业务(eMBMS，Evolved Multimedia Broadcast multicast service Single Frequency Network)在接入网中引入单频网(SFN，Single Frequency Network)传输方式，即多播/组播单频网络(MBSFN，Multimedia Broadcast multicast service Single Frequency Network)，eMBMS就是一种共享网络资源从一个数据源向多个目标传送数据的技术。
eMBMS网络部署中，一个MBSFN区域关联多个小区，关联小区均可以接收MBSFN区域中的MBMS服务。每个小区的无线资源划分为单播无线资源和多播无线资源，多播无线资源用于接收MBMS服务。现有技术中，MBSFN区域的小区管理可以采用静态管理的方式，在规划MBSFN区域时，将MBSFN区域与演进型基站(eNB，evolved Node B)中的小区关联，由多小区多播协调实体(MCE，Multi-cell/multicast Coordination Entity)管理MBSFN区域的小区配置信息。由于一个小区中用户设备(UE，User Equipment)需求具有不确定性，一个小区中接收MBMS服务的UE个数不断发生变化，因此，现有的技术是通过UE多播业务移动连续性，以及MCE侧统计UE计数来扩展MBSFN区域，其对整个MBSFN区域内感兴趣或接收MBMS服务的UE个数进行统计，由MCE决策MBSFN区域是否变化。
然而，采用上述现有技术中的方案，由于MCE侧MBSFN区域统计整 个MBSFN区域UE个数，不能及时关注单个小区的无线资源分配，导致小区资源利用率低，浪费宝贵的无线资源。

需要说明的是，在本发明实施例中，若某一小区属于MBSFN区域的小区，则该某一小区中的UE可以进行MBMS服务。
本发明实施例提供的MBSFN区域的小区管理方法的应用前提为：存在UE正在接收或者感兴趣MBMS服务时。
特别的，本发明实施例中的UE为要进行或感兴趣MBMS服务的UE。
需要说明的是，本发明实施例中的网络侧设备可以为多小区多播协调实体(MCE，Multi-cell/multicast Coordination Entity)。
需要说明的是，实现本发明实施例提供的MBSFN区域的小区管理方法的情况有两种：一种为基站中存在属于MBSFN区域的小区；另一种为基站中不存在属于MBSFN区域的小区。
其中，(1)、首先，基站对至少一个小区中的UE进行MBMS计数统计之前，当基站中存在属于MBSFN区域的小区时，网络侧设备发送MBMS服务统计请求消息至基站，该MBMS服务统计请求消息用于指示该基站对UE进行MBMS计数统计。基站发送与MBMS服务统计请求消息对应的MBMS服务统计响应消息至网络侧设备，该MBMS服务统计响应消息用于表征该基站接受对UE进行MBMS计数统计的请求。然后，基站发送MBMS统计请求消息至UE，该MBMS统计请求消息用于对UE进行MBMS计数统计；UE响应MBMS统计请求消息，发送MBMS统计响应消息至基站，该MBMS统计响应消息用于表征该UE将进行MBMS服务。
可选地，基站接收UE发送的MBMS统计响应消息时，基站确认该UE 所在的小区。
需要说明的是，基站中只有存在属于MBSFN区域的小区，基站才能和网络侧设备进行消息的交互，并且基站在接收到网络侧设备的MBMS服务统计请求消息后，才开始进行对UE的统计工作。
可选地，一个基站中的每个要进行MBMS服务的UE都会发送MBMS统计响应消息给该一个基站，因此，该一个基站可以统计出至少一个小区中的每个小区中的UE的个数。一个基站中不进行MBMS服务的UE不会发送MBMS统计响应消息至基站，这样，基站接收到UE的MBMS统计响应消息时，就统计该UE所在的小区的UE个数加1。
可选地，基站统计UE的个数的实现方式可以使用计数器，该计数器可以采用加数计数器，当一个小区中的UE发送MBMS统计响应消息给基站时，该基站中的对应该一个小区的计数器的值加1。
(2)、基站对至少一个小区中的UE进行MBMS计数统计之前，当基站中不存在属于MBSFN区域的小区时，基站发送系统广播至UE，该系统广播消息中携带MBMS服务信息。UE对MBMS服务感兴趣发送MBMS兴趣指示消息至基站，该MBMS兴趣指示消息用于表征该UE感兴趣MBMS服务。这样，基站主动查询UE要进行MBMS服务的需求，决策基站中的小区是否要加入MBSFN区域的小区。
可选地，基站接收UE发送的MBMS兴趣指示消息时，基站确认该UE所在的小区。
需要说明的是，基站中不存在属于MBSFN区域的小区，基站不能和网络侧设备进行消息的交互，因此，基站主动通过广播对UE进行统计，并在接收到UE发送的MBMS兴趣指示消息后，进行对UE的统计工作。基站是主动的统计的动作。
可选地，一个基站中的每个要进行或感兴趣MBMS服务的UE都会发 送MBMS兴趣指示消息给该一个基站，因此，该一个基站可以统计出至少一个小区中的每个小区中的UE的个数。一个基站中不进行MBMS服务的UE不会发送MBMS兴趣指示消息至基站，这样，基站接收到UE的MBMS兴趣指示消息时，就统计该UE所在的小区的UE个数加1。
可选地，基站统计UE的个数的实现方式可以使用计数器，该计数器可以采用加数计数器，当一个小区中的UE发送MBMS兴趣指示消息给基站时，该基站中的对应该一个小区的计数器的值加1。
可选的，基站与网络侧设备之间通过M2接口进行消息的传输，基站与UE之间通过空口进行消息(空口消息)的传输。
S102、基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区与MBSFN区域的关系。
基站对至少一个小区中的UE进行MBMS计数统计之后，该基站可以根据MBMS计数统计的结果和预设阈值，决策UE所在的小区与MBSFN区域的关系。其中，UE所在的小区与MBSFN区域的关系可以包括：UE所在的小区加入MBSFN区域的小区和UE所在的小区离开MBSFN区域的小区。
可选地，基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区加入MBSFN区域的小区或者离开MBSFN区域的小区。
可选地，当MBMS计数统计的结果大于等于预设阈值，且UE所在的小区不属于MBSFN区域的小区时，基站决策该UE所在的小区加入该MBSFN区域的小区。
当MBMS计数统计的结果小于预设阈值，且UE所在的小区属于MBSFN区域的小区时，基站决策该UE所在的小区离开该MBSFN区域的小区。
可选地，当MBMS计数统计的结果大于等于预设阈值，且UE所在的 小区属于MBSFN区域的小区时，基站决策不改变该UE所在的小区与MBSFN区域的关系。当MBMS计数统计的结果小于预设阈值，且UE所在的小区不属于MBSFN区域的小区时，基站决策不改变该UE所在的小区与MBSFN区域的关系。
需要说明的是，当一个基站中的一个小区中要进行MBMS服务的UE个数较少，且这些UE所在的小区属于MBSFN区域的小区时，若为该一个小区分配了进行MBMS服务的多播无线资源时，由于使用该资源的UE较少，因此，该多播无线资源的利用率比较低，因此，本发明实施例通过对一个小区中的进行或感兴趣MBMS服务的UE进行个数统计，并与预设阈值比较后，将UE个数较多的小区加入MBSFN区域的小区中，以使得该一个小区可以支持MBMS服务。
其中，本发明实施例提供的预设阈值可以为一个数值范围，且该预设阈值的获取是通过针对小区无线资源利用率仿真，合理设置的一个数值范围，可选地预设阈值的选取通过仿真结果来选定。
S103、基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果，以使得该网络侧设备对UE所在的小区执行决策结果。
基站决策UE所在的小区与MBSFN区域的关系之后，该基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果，以使得该网络侧设备对UE所在的小区执行决策结果。在本实施例中所述基站在步骤S103执行的操作包括将决策结果发送给网络侧设备，而网络侧设备在接收到所述决策结果之后，将会对UE所在的小区执行该决策结果。
可以理解的是，在本发明实施例中，基站的主要功能是对至少一个小区的UE个数进行统计，即决策UE所在的每个小区是否要支持MBMS服务。而可选地，将基站决策的结果执行则是由网络侧设备做的，这样，就实现了MBSFN区域对UE所在小区的动态管理。
需要说明的是，在本发明实施例中，基站的上述功能的实现可以由设置在基站中的无线多播资源管理模块进行，即该无线多播资源管理模块的主要功能包括：统计接收或感兴趣MBMS服务UE个数；针对小区无线资源利用率仿真，设置合理的阀值范围；以及根据统计接收或感兴趣MBMS服务UE个数与设置的预设阈值比较，决策小区是否加入或者离开MBSFN区域的小区列表；最后通过M2接口与网络侧设备通信，传输网络侧设备上述小区加入或者离开MBSFN区域的通知消息。
本发明实施例还提供一种MBSFN区域的小区管理方法，如图2所示，为网络设备侧对应的MBSFN区域的小区管理方法，该方法可以包括：
S201、网络侧设备接收基站发送的通知消息，该通知消息中携带该基站的决策结果，该决策结果为该基站决策UE所在的小区与MBSFN区域的关系的结果。
需要说明的是，MBSFN区域的小区是以MBSFN区域的小区列表的形式存在的，因此，网络侧对MBSFN区域的小区的加入或离开是指，将小区的标识加入到MBSFN区域的小区列表，或者将小区的标识从MBSFN区域的小区列表中删除。
可选的，上述决策结果可以包括：UE所在的小区加入MBSFN区域的小区或者离开MBSFN区域的小区。
当网络侧设备接收基站发送的通知消息，该通知消息中携带该基站的决策结果，该决策结果为该基站决策UE所在的小区与MBSFN区域的小区的关系的结果。
可选地，UE所在的第一小区支持MBMS服务(即属于MBSFN区域的小区)时，若基站决策第一小区不接收MBMS服务(即第一小区要离开MBSFN区域的小区)，且这时，该第一小区存在接收MBMS服务的邻区时，该基站则将第一小区中正接收或感兴趣MBMS服务的UE切换或重选到支 持MBMS服务的邻区中，从而保持UE的MBMS业务的连续性；若第一小区不存在接收MBMS服务的邻区，则将第一小区中正在接收或感兴趣MBMS服务的UE进行重定向或重选，其中重定向频点由系统广播(SIB15)提供，从而确保MBMS服务的连续性。同时，基站将第一小区设置为仅支持单播，资源用于优先级高的单播业务，该基站通过M2接口通知网络侧设备上述决策结果，以使得该网络侧设备指示MBSFN区域的小区列表中删除该第一小区。若第一小区不支持MBMS，且基站决策该第一小区需要接收UE的MBMS服务时，该基站决策该第一小区为支持MBMS业务，于是，该基站和网络侧设备通过M2接口发送通知消息，表明基站决策第一小区加入MBSFN区域的小区，以使得该网络侧设备指示MBSFN区域将第一小区加入MBSFN区域小区列表，并且向该第一小区提供MBMS服务。
S202、网络侧设备对UE所在的小区执行决策结果。
网络侧设备接收基站发送的通知消息之后，该网络侧设备对UE所在的小区执行决策结果，由于决策结果可以包括：UE所在的小区加入MBSFN区域的小区或者离开MBSFN区域的小区，因此，网络侧设备对UE所在的小区执行决策结果具体为：所述网络侧设备将所述UE所在的小区加入所述MBSFN区域的小区，或者将所述UE所在的小区离开所述MBSFN区域的小区。
可选地，网络侧设备收到基站发送的通知消息后，根据决策结果在MBSFN区域列表中将UE所在的小区加入或者删除，对于加入MBSFN区域的小区，网络侧设备向该小区发起MBMS服务，使该小区中感兴趣MBMS服务的UE接收MBMS服务。而对于删除MBSFN区域的小区，网络侧设备停止该小区MBMS服务，不再提供MBMS业务。
需要说明的是，MBSFN区域的小区是网络侧设备通过小区列表进行管理的。
本发明实施例所提供的一种MBSFN区域的小区管理方法，基站对至少一个小区中的UE进行MBMS计数统计，该基站为UE的服务基站，该至少一个小区为该基站覆盖的小区；基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区与MBSFN区域的关系；基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果，以使得网络侧设备对UE所在的小区执行决策结果。采用上述技术实现方案，由于基站可以决策UE所在的小区是否要支持MBMS服务，即该基站根据预设阈值和UE的统计个数，就可以决策该UE所在的小区是加入MBSFN区域，还是离开MBSFN区域，这样，就不会存在极少UE所在的小区也要支持MBMS服务的现象，从而不必浪费无线资源，进而达到合理分配无线资源，提升无线资源的利用率的目的。
实施例二
基于MBSFN区域支持MBMS服务，基站下面的第一小区属于MBSFN区域，该第一小区和邻区属于同一个MBSFN区域，且邻区也提供MBMS服务。网络侧设备发起第一小区中的接收或感兴趣MBMS服务UE个数的统计时，以该基站中的第一小区为例，本发明实施例提供一种MBSFN区域的小区管理方法，如图3所示，该方法可以包括：
S301、网络侧设备发送MBMS服务统计请求消息至基站，该MBMS服务统计请求消息用于指示该基站对UE进行MBMS计数统计。

S304、UE响应MBMS统计请求消息，发送MBMS统计响应消息至基 站，该MBMS统计响应消息用于表征该UE将进行MBMS服务。
需要说明的是，在本发明实施例中，若第一小区属于MBSFN区域的小区，则该第一小区中的UE可以进行MBMS服务。
本发明实施例提供的MBSFN区域的小区管理方法的应用前提为：存在UE正在接收或者感兴趣MBMS服务时。
特别的，本发明实施例中的UE为要进行或感兴趣MBMS服务的UE。
需要说明的是，本发明实施例中的网络侧设备可以为MCE。
在本发明实施例中，基站对至少一个小区中的UE进行MBMS计数统计之前，当基站中存在属于MBSFN区域的小区时，网络侧设备发送MBMS服务统计请求消息至基站，该MBMS服务统计请求消息用于指示该基站对UE进行MBMS计数统计。基站发送与MBMS服务统计请求消息对应的MBMS服务统计响应消息至网络侧设备，该MBMS服务统计响应消息用于表征该基站接受对UE进行MBMS计数统计的请求。然后，基站发送MBMS统计请求消息至UE，该MBMS统计请求消息用于对UE进行MBMS计数统计；UE响应MBMS统计请求消息，发送MBMS统计响应消息至基站，该MBMS统计响应消息用于表征该UE将进行MBMS服务。
可选的，基站与网络侧设备之间通过M2接口进行消息的传输，基站与UE之间通过空口进行消息(空口消息)的传输。
S305、基站根据MBMS统计响应消息，对至少一个小区中的UE进行MBMS计数统计。
UE发送MBMS统计响应消息至基站之后，该基站根据MBMS统计响应消息，或者该UE要进行MBMS服务，于是，对至少一个小区中的UE进行MBMS计数统计，即将UE所在小区的UE个数加1。
可选地，基站接收UE发送的MBMS统计响应消息时，基站确认该UE所在的小区。
需要说明的是，基站中只有存在属于MBSFN区域的小区，基站才能和网络侧设备进行消息的交互，并且基站在接收到网络侧设备的MBMS服务统计请求消息后，才开始进行对UE的统计工作。基站是被动的统计的动作。
可选地，一个基站中的每个要进行MBMS服务的UE都会发送MBMS统计响应消息给该一个基站，因此，该一个基站可以统计出至少一个小区中的每个小区中的UE的个数。一个基站中不进行MBMS服务的UE不会发送MBMS统计响应消息至基站，这样，基站接收到UE的MBMS统计响应消息时，就统计该UE所在的小区的UE个数加1。
可选地，基站统计UE的个数的实现方式可以使用计数器，该计数器可以采用加数计数器，当一个小区中的UE发送MBMS统计响应消息给基站时，该基站中的对应该一个小区的计数器的值加1。
S306、基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区离开MBSFN区域的小区。
基站对至少一个小区中的UE进行MBMS计数统计之后，该基站可以根据MBMS计数统计的结果和预设阈值，决策UE所在的小区与MBSFN区域的小区的关系。其中，UE所在的小区与MBSFN区域的小区的关系可以为：UE所在的小区是否离开MBSFN区域的小区。
可选地，基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区是否离开MBSFN区域的小区。
可选地，当MBMS计数统计的结果小于预设阈值，且UE所在的小区属于MBSFN区域的小区时，基站决策该UE所在的小区离开该MBSFN区域的小区。
需要说明的是，当一个基站中的一个小区中要进行MBMS服务的UE个数较少，且这些UE所在的小区属于MBSFN区域的小区时，若为该一个小区分配了进行MBMS服务的多播无线资源时，由于使用该资源的UE较 少，因此，该多播无线资源的利用率比较低，因此，本发明实施例通过对一个小区中的要进行MBMS服务的UE进行个数统计，并与预设阈值比较后，将UE个数较多的小区加入MBSFN区域的小区中，以使得该一个小区可以支持MBMS服务。
其中，本发明实施例提供的预设阈值可以为一个数值范围，且该预设阈值的获取是通过针对小区无线资源利用率仿真，合理设置的一个数值范围，可选地预设阈值的选取通过仿真结果来选定。
S307、基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果。
基站决策UE所在的小区与MBSFN区域的关系之后，该基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果，以使得该网络侧设备对UE所在的小区执行决策结果。
需要说明的是，在本发明实施例中，基站的上述功能的实现可以由设置在基站中的无线多播资源管理模块进行，即该无线多播资源管理模块的主要功能包括：统计接收或感兴趣MBMS服务UE个数；针对小区无线资源利用率仿真，设置合理的阀值范围；以及根据统计接收或感兴趣MBMS服务UE个数与设置的预设阈值比较，决策小区是否离开MBSFN区域的小区列表；最后通过M2接口与网络侧设备通信，传输网络侧设备上述小区离开MBSFN区域的通知消息。
需要说明的是，MBSFN区域的小区是以MBSFN区域的小区列表的形式存在的，因此，网络侧对MBSFN区域的小区的离开是指，将小区的标识从MBSFN区域的小区列表中删除。
可选的，上述决策结果可以为：UE所在的小区离开MBSFN区域的小区。
当网络侧设备接收基站发送的通知消息，该通知消息中携带该基站的 决策结果，该决策结果为该基站决策UE所在的小区与MBSFN区域的小区的关系的结果。
可选地，UE所在的第一小区支持MBMS服务(即属于MBSFN区域的小区)时，若基站决策第一小区不接收MBMS服务(即第一小区要离开MBSFN区域的小区)，且这时，该第一小区存在接收MBMS服务的邻区时，该基站则将第一小区中正接收或感兴趣MBMS服务的UE切换或重选到支持MBMS服务的邻区中，从而保持UE的MBMS业务的连续性；若第一小区不存在接收MBMS服务的邻区，则将第一小区中正在接收或感兴趣MBMS服务的UE进行重定向或重选，其中重定向频点由系统广播(SIB15)提供，从而确保MBMS服务的连续性。同时，基站将第一小区设置为仅支持单播，资源用于优先级高的单播业务，该基站通过M2接口通知网络侧设备上述决策结果，以使得该网络侧设备指示MBSFN区域的小区列表中删除该第一小区。
S308、网络侧设备根据决策结果在MBSFN区域列表中将UE所在的小区删除。
网络侧设备接收基站发送的通知消息之后，该网络侧设备对UE所在的小区执行决策结果，由于决策结果可以包括：UE所在的小区加入MBSFN区域的小区或者离开MBSFN区域的小区，因此，网络侧设备对UE所在的小区执行决策结果具体为：将所述UE所在的小区离开所述MBSFN区域的小区。
可选地，网络侧设备收到基站发送的通知消息后，根据决策结果在MBSFN区域列表中将UE所在的小区删除，对于删除MBSFN区域的小区，网络侧设备停止该小区MBMS服务，不再提供MBMS业务。
需要说明的是，基于MBSFN区域支持MBMS服务，基站下面的第一小区不属于MBSFN区域，该基站下存在属于上述MBSFN区域的小区时， 且邻区提供MBMS服务。网络侧设备发起接收或感兴趣MBMS服务UE个数的统计时，若第一小区不支持MBMS，且基站决策该第一小区需要接收UE的MBMS服务时，该基站决策该第一小区为支持MBMS业务，于是，该基站和网络侧设备通过M2接口发送通知消息，表明基站决策第一小区加入MBSFN区域的小区，以使得该网络侧设备指示MBSFN区域将第一小区加入MBSFN区域小区列表，并且向该第一小区提供MBMS服务。
基于基站中的第一小区属于单播小区，不支持MBMS服务，即MBSFN区域列表中不包括该第一小区，MBSFN区域正在支持MBMS服务，基站统计该第一小区中感兴趣MBMS服务的UE个数的情境下，以该基站中的第一小区为例，本发明实施例还提供一种MBSFN区域的小区管理方法，如图4所示，该方法可以包括：
S401、基站发送系统广播至UE，该系统广播消息中携带频点信息及其频点对应的MBMS服务信息。
S402、UE发送MBMS兴趣指示消息至基站，该MBMS兴趣指示消息用于表征该UE感兴趣MBMS服务。
本发明实施例提供的MBSFN区域的小区管理方法的应用前提为：存在UE正在接收或者感兴趣MBMS服务时。
特别的，本发明实施例中的UE为感兴趣MBMS服务的UE。
需要说明的是，实现本发明实施例提供的MBSFN区域的小区管理方法的情况有两种：一种为基站中存在属于MBSFN区域的小区；另一种为基站中不存在属于MBSFN区域的小区。本发明实施例是在后一种情况下的实现方式。
当基站中不存在属于MBSFN区域的小区时，基站发送系统广播至UE，该系统广播消息中携带频点消息和频点对应的MBMS服务信息。UE发送MBMS兴趣指示消息至基站，该MBMS兴趣指示消息用于表征该UE感兴 趣MBMS服务。这样，基站主动查询UE要进行MBMS服务的需求，决策基站中的小区是否要加入MBSFN区域的小区。
可选地，基站接收UE发送的MBMS兴趣指示消息时，基站确认该UE所在的小区。
需要说明的是，基站中不存在属于MBSFN区域的小区，基站不能和网络侧设备进行消息的交互，因此，基站主动通过广播对UE进行统计，并在接收到UE发送的MBMS兴趣指示消息后，进行对UE的统计工作。基站是主动的统计的动作。
可选地，一个基站中的每个要进行MBMS服务的UE都会发送MBMS兴趣指示消息给该一个基站，因此，该一个基站可以统计出至少一个小区中的每个小区中的UE的个数。一个基站中不进行MBMS服务的UE不会发送MBMS兴趣指示消息至基站，这样，基站接收到UE的MBMS兴趣指示消息时，就统计该UE所在的小区的UE个数加1。
可选地，基站统计UE的个数的实现方式可以使用计数器，该计数器可以采用加数计数器，当一个小区中的UE发送MBMS兴趣指示消息给基站时，该基站中的对应该一个小区的计数器的值加1。
可选的，基站与网络侧设备之间通过M2接口进行消息的传输，基站与UE之间通过空口进行消息(空口消息)的传输。
S403、基站根据MBMS兴趣指示消息，对至少一个小区中的UE进行MBMS计数统计。
可选地，基站可以根据MBMS计数统计的结果和预设阈值，决策UE所在的小区与MBSFN区域的小区的关系，以判断UE所在的小区是否可以加入MBSFN区域的小区。
可选地，当MBMS计数统计的结果大于等于预设阈值，且UE所在的小区不属于MBSFN区域的小区时，基站决策该UE所在的小区加入该 MBSFN区域的小区。
可选地，当MBMS计数统计的结果小于预设阈值，且UE所在的小区不属于MBSFN区域的小区时，基站决策该UE所在的小区不加入MBSFN区域的小区。
其中，本发明实施例提供的预设阈值可以为一个数值范围，且该预设阈值的获取是通过针对小区无线资源利用率仿真，合理设置的一个数值范围，可选地预设阈值的选取通过仿真结果来选定。
可以理解的是，基站收到MBMS Interest Indication(MBMS兴趣指示消息)消息，基站中的无线多播资源模块统计UE个数，UE个数大于预设阈值时，该基站决策UE所在的小区加入MBSFN区域的小区，这样，就将UE所在的小区划分适当的多播无线资源用于MBMS服务，使单播用户和多播用户资源分配合理，从而提升了无线资源的利用率。
S404、基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区加入MBSFN区域的小区。
S405、基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果。
基站决策UE所在的小区与MBSFN区域的小区的关系之后，该基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果，以使得该网络侧设备对UE所在的小区执行决策结果。
需要说明的是，在本发明实施例中，基站的上述功能的实现可以由设置在基站中的无线多播资源管理模块进行，即该无线多播资源管理模块的主要功能包括：统计接收或感兴趣MBMS服务UE个数；针对小区无线资源利用率仿真，设置合理的阀值范围；以及根据统计接收或感兴趣MBMS服务UE个数与设置的预设阈值比较，决策小区是否加入或者离开MBSFN区域的小区列表；最后通过M2接口与网络侧设备通信，传输网络侧设备上 述小区加入或者离开MBSFN区域的通知消息。
S406、网络侧设备将UE所在的小区加入MBSFN区域的小区。
需要说明的是，MBSFN区域的小区是以MBSFN区域的小区列表的形式存在的，因此，网络侧对MBSFN区域的小区的加入是指，将小区的标识加入到MBSFN区域的小区列表上述决策为：UE所在的小区加入MBSFN区域的小区MBSFN区域的小区。
当网络侧设备接收基站发送的通知消息，该通知消息中携带该基站的决策结果，该决策结果为该基站决策UE所在的小区是否加入MBSFN区域的小区的决策结果。
基站发送通知消息至网络侧设备之后，该网络侧设备对UE所在的小区执行决策结果，若决策结果为：UE所在的小区加入MBSFN区域的小区，则网络侧设备对UE所在的小区执行决策结果具体为：网络侧设备将所述UE所在的小区加入MBSFN区域的小区。
其中，当对于加入MBSFN区域的小区具体为：网络侧设备向基站发起MBMS服务的会话流程，以使得UE通过基站获取MBMS服务信息，并根据该MBMS服务信息的标识进行MBMS服务。
需要说明的是，MBSFN区域的小区是网络侧设备通过小区列表进行管理的。
本发明实施例所提供的一种MBSFN区域的小区管理方法，基站对至少一个小区中的UE进行MBMS计数统计，该基站为UE的服务基站，该至少一个小区为该基站覆盖的小区；基站根据MBMS计数统计的结果和预设阈值，决策UE所在的小区与MBSFN区域的关系；基站发送通知消息至网络侧设备，该通知消息中携带基站的决策结果，以使得网络侧设备对UE所在的小区执行决策结果。采用上述技术实现方案，由于基站可以决策UE所在的小区是否要支持MBMS服务，即该基站根据预设阈值和UE的统计 个数，就可以决策该UE所在的小区是加入MBSFN区域，还是离开MBSFN区域，这样，就不会存在极少UE所在的小区也要支持MBMS服务的现象，从而不必浪费无线资源，进而达到合理分配无线资源，提升无线资源的利用率的目的。
