具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。在下面的描述中，提供诸如具体的配置和组件的特定细节仅仅是为了帮助全面理解本公开的实施例。因此，本领域技术人员应该清楚，可以对这里描述的实施例进行各种改变和修改而不脱离本公开的范围和精神。另外，为了清楚和简洁，省略了对已知功能和构造的描述。
应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此，在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必 一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本公开实施例的实施过程构成任何限定。
本公开实施例中术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。在本申请所提供的实施例中，应理解，“与A相应的B”表示B与A相关联，根据A可以确定B。但还应理解，根据A确定B并不意味着仅仅根据A确定B，还可以根据A和/或其它信息确定B。
本公开实施例中，接入网的形式不限，可以是包括宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(第三代(3 rd Generation，3G)移动基站的称呼)、增强型基站(eNB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HeNB)、中继站、接入点、远端射频模块(Remote Radio Unit，RRU)、射频拉远头(Remote Radio Head，RRH)等的接入网。用户终端可以是移动电话(或手机)，或者其他能够发送或接收无线信号的设备，包括用户设备、个人数字助理(personal digital assistant，PDA)、无线调制解调器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(wireless local loop，WLL)站、能够将移动信号转换为无线保真(wireless fidelity，WiFi)信号的客户终端(Customer Premise Equipment，CPE)或移动智能热点、智能家电、或其他不通过人的操作就能自发与移动通信网络通信的设备等。
在进行本公开实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
单小区点到多点(Single Cell-Point to Multipoint，SC-PTM)技术下的MBMS控制信息变化的通知机制：
当服务小区上的MBMS业务发生变化时，会导致MBMS控制信道(Single Cell-Multicast Control Channel，SC-MCCH)上传输的MBMS控制消息内容的 变化。当MBMS控制消息发生变化时，终端(user equipment，UE)需要及时的获取更新的MBMS控制消息。为了避免UE为了获取更新的MBMS控制消息而连续监听MBMS控制信道，从而导致不必要的耗电，在SC-PTM上设计了专门的MBMS控制消息变化通知机制，如图1所示，即为了传输MBMS控制消息的改变定义了专门的修改周期(Modification Period)和重复周期(repetition period)，网络控制只在修改周期内的特定位置更新MBMS控制信息，在一个修改周期内更新的MBMS控制消息可每隔一个重复周期重复发送多次。
如果发生MBMS控制消息的变化，则接入网通过PDCCH上特定格式的DCI信息的一个比特位指示，用于指示的PDCCH通过一个特定的RNTI(即SC-N-RNTI)进行加扰以便于UE区分。处于空闲态未接受MBMS业务但对MBMS业务感兴趣的UE只需在特定位置监听SC-N-RNTI指示的PDCCH，进而判断MBMS控制消息是否发生变化，进而根据指示接收更新的MBMS控制消息。
其中，通过SC-N-RNTI指示的PDCCH上的DCI中的一个信息比特指示的MBMS控制消息的变化时，由于小区中的任何一个MBMS业务发生变化都会导致SC-MCCH上的MBMS控制消息的变化，小区内所有UE都需要根据PDCCH DCI的指示去获取更新的多播控制消息，只有获取到更新的多播控制消息后才能知道是否本UE关心的MBMS业务发生了变化，这样会导致部分MBMS业务的变化导致UE不必要的接收更新的MBMS控制消息。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，并不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
具体地，如图2所示，本公开的实施例提供了一种MBMS控制消息变化的通知方法，应用于终端，包括：
步骤201、根据多媒体广播多播业务MBMS被划分的多个MBMS业务组，通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示。
该实施例中，网络侧设备将小区内所有的MBMS业务划分为多个MBMS业务组。可选地，可以根据MBMS业务标识划分，例如：根据临时移动群组标识(Temporary Mobile Group Identity，TMGI)划分，每一个TMGI属于不同的MBMS业务组，且网络侧设备需要向终端配置对MBMS业务分组所需的参数，终端根据MBMS业务分组所需的参数，能够得知其所关心的MBMS业务所属的MBMS业务组。当MBMS业务变化导致MBMS控制消息发生变化时，网络侧设备按照MBMS业务组对应的传输方式向终端发送MBMS控制消息更新指示，则终端根据其关心的目标MBMS业务所属的MBMS业务组相对应的传输方式，监听所述目标MBMS业务的MBMS控制消息更新指示，并相应的接收更新的MBMS控制消息。
本申请的实施例，对于MBMS控制信道上的MBMS控制消息的变化，网络侧根据MBMS业务所属的MBMS业务组进行分组通知，终端根据目标MBMS业务所属的MBMS业务组，接收MBMS控制消息更新指示，减少了UE接收与本UE无关的MBMS控制消息更新指示的过程，避免不必要的耗电。
具体地，在通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示之前，所述方法还包括：
接收将MBMS业务划分为多个MBMS业务组的指示参数；根据所述指示参数，确定目标MBMS业务所属的目标MBMS业务组。
网络侧设备在将小区内的所有MBMS业务进行分组时，需要将分组依据的参数以及分组指示发送至终端，如：分组数量、分组算法。终端根据网络侧设备的指示以及相关参数能够确定各个MBMS业务所属的MBMS业务组，从而与网络侧设备的分组一致。例如：网络侧设备根据MBMS业务标识(如TMGI)对MBMS业务进行分组，相同的业务标识属于同一MBMS业务组，或者，业务标识的取值在一预设区间内的MBMS业务属于同一MBMS业务组。需要说明的是，对于MBMS业务进行分组的具体依据不做限定，可以根据需求设置。
进一步地，在根据多媒体广播多播业务MBMS被划分的多个MBMS业 务组，通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示时，可以包括但不限于以下几种方式：
方式一：不同MBMS业务对应的MBMS控制信息的变化在不同的时间点指示。
具体地，所述步骤201包括：在所述目标MBMS业务组对应的目标接收时间点，监听单小区通知无线网络临时标识SC-N-RNTI指示的物理下行控制信道PDCCH；所述PDCCH中的下行控制信息DCI携带所述MBMS控制消息更新指示。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，在MBMS控制信道的修改周期内的不同的时间点使用SC-N-RNTI指示的PDCCH上的DCI信息携带每个MBMS业务组的对应的业务变化通知，即每个时间点对应一个MBMS业务组的业务变化通知。终端根据所述目标MBMS业务所属的目标MBMS业务组，在该目标MBMS业务组对应的接收时间点监听SC-N-RNTI指示的PDCCH，在监听到所述PDCCH中的DCI信息携带了MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
具体地，在通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示之前，所述方法还包括：接收每个MBMS业务组对应的接收时间点的信息。其中，为了实现该方式一，网络侧设备在向终端发送MBMS控制消息更新指示之前，需要向UE配置对MBMS业务分组所需的参数，以及每个MBMS业务组的变化通知的发送时间点的相关参数，如相对修改周期起始点的时间偏移量，以使终端能够在相应的时间点监听SC-N-RNTI指示的PDCCH。
下面通过具体示例说明所述方式一的实现过程。
示例一，如图3所示：
1)：UE接收网络侧设备发送的MBMS业务分组相关参数，如分组数量，分组算法。并计算出UE关心的MBMS业务所对应的MBMS业务组(即目标MBMS业务所对应的目标MBMS业务组)。UE同时接收每个MBMS业务 组业务变化通知的发送时间点的相关参数，如相对修改周期起始点的时间偏移量。
2)：UE在目标MBMS业务组对应的接收时间点监听对应的SC-N-RNTI指示的PDCCH；
3)：当UE在PDCCH上接收到MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
方式二：不同MBMS业务对应的MBMS控制信息的变化在相同时间点的不同频域位置指示。
具体地，所述步骤201可以包括：在所述目标MBMS业务组对应的目标频域资源，监听SC-N-RNTI指示的PDCCH；所述PDCCH中的DCI信息携带所述MBMS控制消息更新指示。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，在MBMS控制信道的修改周期内的不同频域资源上使用相同的SC-N-RNTI指示的PDCCH上的DCI信息携带每个MBMS业务组的对应的业务变化通知，即每个频域资源上DCI对应一个MBMS业务组的业务变化通知。终端根据所述目标MBMS业务所属的目标MBMS业务组，在该目标MBMS业务组对应的目标频域资源上，监听SC-N-RNTI指示的PDCCH，在监听到所述PDCCH中的DCI信息携带了MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
具体地，在通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示之前，所述方法还包括：接收每个MBMS业务组对应的频域资源的信息。其中，为了实现该方式二，网络侧设备在向终端发送MBMS控制消息更新指示之前，需要向终端配置对MBMS业务分组所需参数，以及每个MBMS业务组变化通知所对应频域资源的相关参数，如频域偏移量。以使终端能够在相应的频域资源位置监听SC-N-RNTI指示的PDCCH。
下面通过具体示例说明所述方式二的实现过程。
示例二，如图4所示：
1)：UE接收网络侧设备发送的MBMS业务分组相关参数，如分组数量， 分组算法。并计算出UE关心的MBMS业务所对应的MBMS业务组(即目标MBMS业务所对应的目标MBMS业务组)。UE同时接收每个MBMS业务组业务变化通知发送频域资源的相关参数，如频域偏移量等。
2)：UE在目标MBMS业务组所对应的频域资源上监听SC-N-RNTI指示的PDCCH；
3)：当UE在PDCCH上接收到MBMS控制消息变化指示时，即到相应的位置接收更新的MBMS控制消息。
方式三：不同MBMS业务组对应不同的SC-N-RNTI取值。
具体地，所述步骤201可以包括：监听所述目标MBMS业务组对应的目标SC-N-RNTI指示的PDCCH；所述目标SC-N-RNTI指示的PDCCH的DCI信息携带所述MBMS控制消息更新指示。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，每个MBMS业务组使用独立的SC-N-RNTI指示的PDCCH上的DCI信息进行业务变化的指示，分属于不同MBMS业务组的UE只需监听对应的SC-N-RNTI(即目标SC-N-RNTI)指示的PDCCH信道。终端监听本UE所属的MBMS业务组对应的目标SC-N-RNTI指示的PDCCH，当接收到MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
可选地，在通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示之前，所述方法还包括：接收每个MBMS业务组对应的SC-N-RNTI取值的信息。其中，为了实现该方式三，网络侧设备在向终端发送MBMS控制消息更新指示之前，需要向终端配置对MBMS业务分组所需的参数，以及每个MBMS业务组所对应的SC-N-RNTI的取值。以使终端能够监听目标MBMS业务组对应的目标SC-N-RNTI指示的PDCCH。
下面通过具体示例说明所述方式三的实现过程。
示例三，如图5所示：
1)：UE接收网络侧设备发送的MBMS业务分组相关参数，如分组数量，分组算法。并计算出UE关心的MBMS业务所对应的MBMS业务组(即目标MBMS业务所对应的目标MBMS业务组)。UE同时接收网络侧设备发送 的每个MBMS业务组对应的SC-N-RNTI的取值；
2)：UE监听目标MBMS业务组对应的目标SC-N-RNTI指示的PDCCH；
3)：当UE在PDCCH上接收到MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
方式四：PDCCH上的下行控制信息DCI中的信息比特分别指示不同MBMS业务组的变化。
具体地，所述步骤201可以包括：在MBMS控制信道修改周期内监听SC-N-RNTI指示的PDCCH；所述PDCCH的DCI信息包括：与所述目标MBMS业务组对应的目标信息比特，所述目标信息比特指示所述目标MBMS业务对应的MBMS控制消息的更新情况。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，对SC-N-RNTI指示的PDCCH中的DCI信息的格式增加信息比特，每个信息比特分别对应不同的MBMS业务组，用于指示所对应的MBMS业务组内是否有MBMS业务发生了变化。终端监听网络侧设备通过无线接入网临时标识(如SC-N-RNTI)指示的PDCCH，检查UE关心的MBMS业务所属的MBMS业务组(即所述目标MBMS业务所对应的目标MBMS业务组)所对应的PDCCH上的目标信息比特，当对应的信息比特指示MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
可选地地，在通过与目标MBMS业务所属的MBMS业务组相对应的传输方式，接收所述目标MBMS业务的MBMS控制消息更新指示之前，所述方法还可以包括：接收每个MBMS业务组对应的DCI信息的信息比特的信息。其中，为了实现该方式四，网络侧设备在向终端发送MBMS控制消息更新指示之前，需要定义新的DCI格式，使其中的不同信息比特指示不同MBMS业务组的MBMS业务组，且网络侧设备需要向终端配置对MBMS业务分组所需参数，以及每个MBMS业务组对应的DCI信息的信息比特的信息，以使终端检测目标业务组对应的目标信息比特的指示内容。
下面通过具体示例说明所述方式四的实现过程。
示例四，如图6所示：
1)：UE接收网络侧设备发送的MBMS业务分组相关参数，如分组数量， 分组算法。并计算出UE关心的MBMS业务所对应的MBMS业务组(即目标MBMS业务所对应的目标MBMS业务组)；
2)：UE开始在MBMS控制信道修改周期内监听无线接入网临时标识(如SC-N-RNTI)指示的PDCCH；
3)：当目标MBMS业务发生变化时，网络侧设备根据目标MBMS业务所对应的目标MBMS业务组，设置相应PDCCH上的DCI中的目标信息比特，并向UE发送。
4)：UE在无线接入网临时标识(如SC-N-RNTI)指示的PDCCH的目标信息比特中检测到所述目标MBMS业务组对应MBMS控制消息的变化；
5)：UE到相应的位置的MBMS控制信道上接收更新的MBMS控制消息。

该实施例中，网络侧设备将小区内所有的MBMS业务划分为多个MBMS业务组。可选地，可以根据MBMS业务标识划分，例如：根据TMGI划分，每一个TMGI属于不同的MBMS业务组，且网络侧设备需要向终端配置对MBMS业务分组所需的参数，如分组数量、分组算法等。以使终端能够得知其MBMS业务所属的MBMS业务组。
当MBMS业务变化导致MBMS控制消息发生变化时，网络侧设备按照MBMS业务组对应的传输方式向终端发送MBMS控制消息更新指示，以使终端监听目标MBMS业务的MBMS控制消息更新指示。
该实施例对于MBMS控制信道上的MBMS控制消息的变化，网络侧将小区内的所有MBMS业务划分为多个MBMS业务组，在目标MBMS业务对应的MBMS控制消息发生变化时，根据目标MBMS业务所属的MBMS业务组进行分组通知，以使终端根据目标MBMS业务所属的MBMS业务组，接收MBMS控制消息更新指示，减少了UE接收与本UE无关的MBMS控制消息更新指示的过程，避免不必要的耗电。
可选地，在对MBMS业务进行分组时，可以根据MBMS业务的MBMS业务标识，对所述MBMS业务进行分组；其中，不同的MBMS业务标识对应不同的MBMS业务组。在根据MBMS业务的MBMS业务标识，对所述MBMS业务进行分组之后，所述方法还包括：向终端发送将MBMS业务划分为多个MBMS业务组的指示参数。
络侧设备在将小区内的所有MBMS业务进行分组时，需要将分组依据的参数以及分组指示发送至终端，如：分组数量、分组算法，以使终端根据网络侧设备的指示以及相关参数确定MBMS业务所属的MBMS业务组。例如：网络侧设备根据MBMS业务标识(如TMGI)对MBMS业务进行分组，相同的业务标识属于同一MBMS业务组，或者，业务标识的取值在一预设区间内的MBMS业务属于同一MBMS业务组。需要说明的是，对于MBMS业务 进行分组的具体依据不做限定，可以根据需求设置。
进一步地，所述步骤701可以包括：在所述目标MBMS业务组对应的目标接收时间点，发送所述MBMS控制消息更新指示；所述MBMS控制消息更新指示由单小区通知无线网络临时标识SC-N-RNTI指示的物理下行控制信道PDCCH中的下行控制信息DCI携带。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，在MBMS控制信道的修改周期内的不同的时间点使用SC-N-RNTI指示的PDCCH上的DCI信息携带每个MBMS业务组的对应的业务变化通知，即每个时间点对应一个MBMS业务组的业务变化通知。
具体地，在在通过与所述目标MBMS业务所属的MBMS业务组相对应的传输方式，向终端发送MBMS控制消息更新指示之前，所述方法还包括：配置每个MBMS业务组对应的接收时间点；向终端发送所述每个MBMS业务组对应的接收时间点的信息。网络侧设备在向终端发送MBMS控制消息更新指示之前，需要向UE配置对MBMS业务分组所需的参数，以及每个MBMS业务组的变化通知的发送时间点的相关参数，如相对修改周期起始点的时间偏移量，以使终端能够在相应的时间点监听SC-N-RNTI指示的PDCCH。
终端根据所述目标MBMS业务所属的目标MBMS业务组，在该目标MBMS业务组对应的接收时间点监听SC-N-RNTI指示的PDCCH，在监听到所述PDCCH中的DCI信息携带了MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
进一步地，所述步骤701可以包括：在所述目标MBMS业务组对应的目标频域资源，发送所述MBMS控制消息更新指示；所述MBMS控制消息更新指示由SC-N-RNTI指示的PDCCH中的DCI携带。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，在MBMS控制信道的修改周期内的不同频域资源上使用相同的SC-N-RNTI指示的PDCCH上的DCI信息携带每个MBMS业务组的对应的业务变化通知，即每个频域资源上DCI对应一个MBMS业务组的业务变化通知。
在通过与所述目标MBMS业务所属的MBMS业务组相对应的传输方式，向终端发送MBMS控制消息更新指示之前，所述方法还包括：配置每个 MBMS业务组对应的频域资源；向终端发送所述每个MBMS业务组对应的频域资源的信息。网络侧设备在向终端发送MBMS控制消息更新指示之前，需要向终端配置对MBMS业务分组所需参数，以及每个MBMS业务组变化通知所对应频域资源的相关参数，如频域偏移量。以使终端能够在相应的频域资源位置监听SC-N-RNTI指示的PDCCH。
终端根据所述目标MBMS业务所属的目标MBMS业务组，在该目标MBMS业务组对应的目标频域资源上，监听SC-N-RNTI指示的PDCCH，在监听到所述PDCCH中的DCI信息携带了MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
进一步地，所述步骤701可以包括：向终端发送所述目标MBMS业务组对应的目标SC-N-RNTI的取值；所述MBMS控制消息更新指示由所述目标SC-N-RNTI指示的PDCCH中的DCI携带。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，每个MBMS业务组使用独立的SC-N-RNTI指示的PDCCH上的DCI信息进行业务变化的指示，分属于不同MBMS业务组的UE只需监听对应的目标SC-N-RNTI指示的PDCCH信道。
在通过与所述目标MBMS业务所属的MBMS业务组相对应的传输方式，向终端发送MBMS控制消息更新指示之前，所述方法还包括：配置每个MBMS业务组对应的SC-N-RNTI的取值；向终端发送所述每个MBMS业务组对应的SC-N-RNTI取值的信息。网络侧设备在向终端发送MBMS控制消息更新指示之前，需要向终端配置对MBMS业务分组所需的参数，以及每个MBMS业务组所对应的SC-N-RNTI的取值。以使终端能够监听目标MBMS业务组对应的目标SC-N-RNTI指示的PDCCH。
终端监听本UE所属的MBMS业务组对应的目标SC-N-RNTI指示的PDCCH，当接收到MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
进一步地，所述步骤701可以包括：向终端发送SC-N-RNTI指示的PDCCH的DCI信息；所述DCI信息包括：与所述目标MBMS业务组对应的目标信息比特，所述目标信息比特指示所述目标MBMS业务对应的MBMS 控制消息的更新情况。
该实施例中，网络侧设备将小区内的所有MBMS业务进行分组后，对SC-N-RNTI指示的PDCCH中的DCI信息的格式增加信息比特，每个信息比特分别对应不同的MBMS业务组，用于指示所对应的MBMS业务组内是否有MBMS业务发生了变化。
可选地，在通过与所述目标MBMS业务所属的MBMS业务组相对应的传输方式，向终端发送MBMS控制消息更新指示之前，所述方法还包括：配置每个MBMS业务组对应的DCI信息中的信息比特；向终端发送所述每个MBMS业务组对应的DCI信息的信息比特的信息。网络侧设备在向终端发送MBMS控制消息更新指示之前，需要定义新的DCI格式，使其中的不同信息比特指示不同MBMS业务组的MBMS业务组，且网络侧设备需要向终端配置对MBMS业务分组所需参数，以及每个MBMS业务组对应的DCI信息的信息比特的信息，以使终端检测目标业务组对应的目标信息比特的指示内容。
终端监听网络侧设备通过无线接入网临时标识(如SC-N-RNTI)指示的PDCCH，检查UE的目标MBMS业务所对应的目标MBMS业务组所对应的PDCCH上的目标信息比特，当对应的信息比特指示MBMS控制消息更新指示时，即到相应的位置接收更新的MBMS控制消息。
