多播组播业务控制信息的传输和获取方法及装置 技术领域
本发明涉及通信技术， 特别是涉及一种多播组播业务控制信息的传输和 获取方法及装置。 背景技术
增强的多播组播业务 ( Envoi ved Multimedia Broadcast Multicast Se rvice, 简称 EMBMS )是第三代移动通信全球标准化组织 （3rd Generation P artnership Project, 简称 3GPP)提出的移动通信网络中多播组播业务（ Mul timedia Broadcast Multicast Service, 简称 MBMS) 的演进业务， 其支持 在空中接口上采用单频网（Single frequency network,简称 SFN)方式传输 M BMS数据， 即 SFN覆盖区域（Single Frequency Network Area, 简称 SFA) 内的多个小区同时采用相同的时频资源传输相同的 MBMS。 用户设备（User E quipment, 简称 UE )对接收的 MBMS数据进行空口合并， 提高了分集增益。
3GPP提出的 TS36.300协议定义用于传输 MBMS 的逻辑信道包括： MBMS 控制信道（MBMS Control Channel, 简称 MCCH)和 MBMS业务信道（MBMS Tr aff ic Channel, 简称 MTCH ) ， 由于 MCCH需要及时通知 UE关于 MBMS的控制 信息， 因此 UE要接收 MBMS业务， 必须首先接收 MCCH上承载的 MBMS控制信 息。 为了实现 SFA内各小区传输 MBMS的差异性控制， 例如： 在 SFA内多个小 区中， 一个或部分小区可传输 MBMS的控制信息以及 MBMS的业务数据， 一个 或部分小区只传输 MBMS的业务数据， 现有技术采用将逻辑信道 MCCH划分为 主 MCCH和辅 MCCH。 其中， 各小区的辅 MCCH用于以 SFN方式传输所有 MBMS 业务的控制信息， 各小区的主 MCCH承载有本小区内可用的 MBMS业务的控制 信息的辅 MCCH的位置信息。 UE首先获取本小区的主 MCCH消息， 根据获取的 主 MCCH小区确定相应的辅 MCCH的位置，并从该位置对应的辅 MCCH获取本小 区可用的 MBMS的控制信息。由于各小区可^^据本小区自身可用的业务情况进 行主 MCCH承载控制信息的设置， 例如在实现 SFA内一个或部分小区只传输 M BMS的业务数据的控制， 可不在广播消息中指示关于主 MCCH的信息， 这样， 无论这些小区实际上是否传输了主 MCCH消息和辅 MCCH消息， UE无法获取主 MCCH的信息， 因此 UE不能在这些小区上接收控制信息， 从而实现网络侧对 S FA内各小区传输 MBMS的差异性控制。
发明人在实现本发明实施例过程中发现，现有技术通过对 MCCH进行分级 的方式进行 SFA内各小区传输 MBMS的差异性控制， 网络侧发送 MCCH消息过 程以及 UE接收 MCCH消息的过程均需涉及多级操作， 如对主 MCCH消息和辅 M CCH 消息分别进行从逻辑信道到传输信道、 传输信道到物理信道之间信道映 射的多级操作， 因而实现方式较为复杂。 发明内容
本发明实施例提供一种多播组播业务控制信息的传输和获取方法及装 置， 用以降低单频网覆盖区域内， 各小区传输多播组播业务的差异性控制的 实现复杂度。
本发明实施例提供了一种多播组播业务控制信息的传输方法， 包括： 在单频网覆盖区域内的多个小区以单频网方式发送所述单频网覆盖区域 支持的各业务的业务索引以及与所述业务索引相应的多播组播业务 MBMS 的 控制信息；

本发明实施例还提供了一种多播组播业务控制信息的获取方法， 包括： 接收单频网覆盖区域内用户设备当前所在小区单播或小区广播的多播组 播业务 MBMS的业务索引；
通过物理多播信道获取与所述业务索引相应的 MBMS的控制信息。
本发明实施例还提供了另一种多播组播业务控制信息的传输方法， 包 括：
将用于传输多播组播业务 MBMS控制信息的物理多播信道配置为主物理 多播信道和辅物理多播信道；
通过所述辅物理多播信道， 发送单频网覆盖区域内各 MBMS的控制信息； 通过所述主物理多播信道， 发送所述辅物理多播信道上承载所述单频网 覆盖区域内各小区自身相关的 MBMS的控制信息的位置信息。
本发明实施例还提供了一种网络设备， 包括：
控制信息发送模块， 用于在单频网覆盖区域内的多个小区以单频网方式 发送所述单频网覆盖区域支持的各业务的业务索引以及与所述业务索引相应 的多播组播业务 MBMS的控制信息；
业务索引发送模块， 用于在所述单频网覆盖区域内的小区， 单播或小区 广播各小区自身支持的 MBMS的业务索引，以使得用户设备获取所述用户设备 当前所在小区支持的业务索引，并从所述 MBMS的控制信息中获取与所述当前 所在小区支持的业务索引相应的 MBMS的控制信息。
本发明实施例还提供了一种用户设备， 包括：
业务索引接收模块， 用于接收单频网覆盖区域内用户设备当前所在小区 的单播消息或小区广播消息， 所述单播消息或小区广播消息包括所述当前所 在小区自身支持的多播组播业务 MBMS的业务索引；
控制信息接收模块， 用于通过物理多播信道获取与所述业务索引相应的 MBMS的控制信息。
本发明实施例还提供了另一种网络设备， 包括：
信道资源配置模块，用于将用于传输 MBMS控制信息的物理多播信道配置 为主物理多播信道和辅物理多播信道；
控制信息发送模块， 通过所述辅物理多播信道， 发送单频网覆盖区域内 各 MBMS的控制信息；
位置信息发送模块， 用于通过所述主物理多播信道， 发送所述辅物理多 播信道上承载所述单频网覆盖区域内各小区自身相关的 MBMS 的控制信息的 位置信息。
本发明实施例在 SFA区内的各小区传输相同的 MBMS的控制信息，不同小 区向 UE单播或小区广播的业务索引可以相同或不同， 使得 UE在 SFA内的不 同小区中获取的信息可以相同或不同， 因此， 本发明实施例即保证了 UE接收 MBMS控制信息的分集增益， 同时又可实现 SFA内多小区传输 MBMS的差异性 控制， 且实现方法简单。 本发明实施例可应用与单个 SFA内各小区传输 MBMS 的差异性控制， 还可应用于多个 SFA交叠处的小区传输 MBMS的差异性控制， 因而具有较强的通用性。 附图说明
为了更清楚地说明本发明实施例的技术方案， 下面将对实施例描述中所 需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本发 明的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动性的 前提下， 还可以根据这些附图获得其他的附图。

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， 所描述的实施例仅仅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付 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。
图 1为本发明第一实施例提供的 MBMS控制信息的传输方法流程图。本实施 例的执行主体可为某种网络设备， 即本实施例从网络侧说明 MBMS控制信息的 传输方法。 如图 1所示， 本实施例 MBMS控制信息的传输方法， 包括：
步骤 11、 在单频网覆盖区域（SFA ) 内的多个小区以单频网 （SFN )方式 发送 SFA支持的各业务的业务索引以及与上述业务索引相应的 MBMS的控制信 本步骤是在 SFA内各小区以 SFN方式传输相同的 MBMS控制信息， 以使 U E通过空口接收 MBMS数据可获得较大的分集增益。
步骤 12、 在 SFA内的小区， 单播或小区广播各小区自身支持的 MBMS的 业务索引， 以使得用户设备获取用户设备当前所在小区支持的业务索引， 并 从上述 MBMS的控制信息中获取与上述当前所在小区支持的业务索引相应的 M BMS的控制信息。
MBMS的业务索引可预先建立， 且建立的方式不受限制。 业务索引可对应 一个 MBMS业务， 如为该 MBMS业务的 ID, 进一步的， 业务索引还可对应包括 二个或二个以上 MBMS的业务组， 如为由三个 MBMS组成的业务组的标识。 本 步骤通过各小区以单播或小区广播方式将各小区支持的业务索引通知 UE， 其 中单播方式即为点到点的传输方式， 小区广播方式即为在本小区覆盖范围内 点到多点的传输方式。
UE通过单播或小区广播消息可获取当前所在小区支持的业务索引， 然后 在 MCCH中查找业务索引相应的一个或多个业务的控制信息，从这些控制信息 中选出自身所需业务， 并在 MTCH上接收相应的业务数据。
本实施例上述技术方案中，步骤 11和步骤 12之间没有时序关系的限制， 即步骤 12可发生在步骤 11之前或之后， 还可与步骤 12同步发生。 其中， M BMS的业务索引可预先建立， 建立的方式不受限制。
本实施例在 SFA区内的各小区传输相同的 MBMS的控制信息，不同小区向 UE单播或小区广播的业务索引可以相同或不同， 使得 UE在 SFA内的不同小 区中获取的信息可以相同或不同， 因此， 本实施例即保证了 UE接收 MBMS控 制信息的分集增益， 同时又可实现了 SFA内多小区传输 MBMS的差异性控制。
相对于对逻辑信道（如 MCCH )进行主辅分级处理的现有方案而言， 本实 施例提供了一种实现不同小区传输 MBMS能力的差异性控制的新方法，在网络 侧向发送 MBMS控制信息的过程没有对逻辑信道分级， 不需要对分级后主 MCC H和辅 MCCH分别进行从逻辑信道到传输信道、 传输信道到物理信道之间信道 映射的多级操作， 因此明显降低了实现的复杂度； 本实施例可应用与单个 SF A内各小区传输 MBMS的差异性控制， 还可应用于多个 SFA交叠处的小区传输 MBMS的差异性控制， 因而具有较强的通用性。
图 2为本发明第二实施例提供的 MBMS控制信息的获取方法流程图。 与图 1 对应实施例的区别在于， 本实施例的执行主体可为某种用户设备， 即本实施 例从终端侧说明 MBMS控制信息的获取方法。 如图 2所示， 本实施例 MBMS控制信 息的获取方法， 包括：
步骤 21、 接收单频网覆盖区域（SFA ) 内用户设备当前所在小区单播或 小区广播的多播组播业务（MBMS ) 的业务索引。
网络设备在 SFA内的每一小区中， 单播或小区广播本小区自身支持的多 播组播业务 MBMS的业务索引，该单播消息或小区广播消息携带有本小区自身 支持的多播组播业务 MBMS 的业务索引。 UE通过单播或小区广播消息可获取 当前所在小区支持的业务索引，然后在 MCCH中查找业务索引相应的一个或多 个业务的控制信息， 从这些控制信息中选出自身所需的业务， 并在 MTCH上接 收相应的业务数据。
步骤 22、 通过物理多播信道（Physical MBMS Channel, 简称 PMCH )获 取与上述业务索引相应的 MBMS的控制信息。
网络设备在 SFA内的各小区以 SFN方式传输 SFA内的各 MBMS的控制信息。 逻辑信道，如 MCCH信道上传输的各 MBMS的控制信息被映射到多播传输信道， 之后被映射到 PMCH上发送。 UE在 PMCH上查找自身选出的业务索引相应的一 个或多个业务的控制信息， 根据这些控制信息在 MTCH 上接收相应的业务数 据。
下面以 3GPP定义的三类小区为例，对本实施例实现对 SFA内各小区传输 MBMS的差异性控制的机理进行说明。
根据 3GPP TS36.3000协议规定， SFA区内各小区根据传输内容的不同， 可分为以下三类小区：
1、 传输和广告小区 ( Transmitting and Advertising Cell, 简称 T&A 小区） ： 传输 MBMS的控制信息以及 MBMS的业务数据。
2、 传输小区 (Transmitting- Only Cell, 简称 T- 0小区） ： 传输 MBMS 的业务数据。
3、 保留小区（Reserved Cell )： 既不传输 MBMS的控制信息， 也不传输 MBMS的业务数据。
在各小区传输 MBMS的控制信息的差异性控制的具体实现过程中，可根据 实际需要将各小区配置为不同类型的小区。
基于本发明上述图 1和图 2对应的实施例提供的方法， 可通过对各小区 单播或小区广播消息的控制，较易实现 SFA内各小区传输 MBMS的差异性控制。 举例说明：
图 3a为本发明 SFA内各小区传输 MBMS的差异性控制应用场景一示意图。 如图 3a所示， 假设 SFA内包括 6个小区， 分别表示为： 小区 1、 小区 2、 小 区 3、 小区 4、 小区 5和小区 6。 网络设备需要将小区 1、 小区 3、 小区 4和 小区 5配置为传输和广告小区， 将小区 6配置为传输小区， 并将小区 2配置 为保留小区。
( 1 )传输和广告小区的实现
可将小区 1、小区 3、小区 4和小区 5各单播或小区广播消息中携带各小 区支持的业务对应的业务索引， UE可根据这些业务索引在 PMCH上获取与这 些业务索引相应的 MBMS的控制信息， 并根据获取的控制信息获取 MTCH上承 载的业务数据。 由于小区 1、 小区 3、 小区 4和小区 5可传输 MBMS的控制信 息， 也可提供 MBMS的业务数据， 因而小区 1、 小区 3、 小区 4和小区 5即为 传输和广告小区。
( 2 )传输小区的实现
可在小区 6的单播或小区广播消息中广播本小区提供 MBMS业务数据但本 小区无可用的业务索引。 如此处理之后， 相对于 UE而言， UE不会在小区 6 内获取 MBMS的控制信息，但可在小区 6内通过 SFN方式提高 UE接收 MBMS数 据的分集增益。 可见， 在小区 6内实际传输的信息为 MBMS的业务数据， 且没 有 MBMS的控制信息， 因而小区 6即为传输小区。
( 3 )保留小区的实现
可在小区 2的单播消息中广播本小区不提供 MBMS业务数据，还可提供本 小区无可用的业务索引。 如此处理之后， 相对于 UE而言， UE不会在小区 2 内获取 MBMS的控制信息以及 MBMS的业务数据， 该情形下， 小区 2即为保留 小区。
通过上述分析可见，由于各小区单播或小区广播消息设置方式非常灵活， 在通过 SFN方式发送 MBMS的控制信息之后，可通过各小区的单播或小区广播 消息对各小区传输的 MBMS进行差异化控制， 实现方式较为简单。
在上述技术方案中， 业务索引的建立方式非常灵活， 例如： 可为 SFA内 的每个 MBMS建立一个业务索引。 如图 3a所示的应用场景中， 殳 SFA内包 括 4个 MBMS , 为每个 MBMS建立一个业务索引， 如： A、 B、 C和 D， 用 4个业 务索引 A、 B、 C和 D分别用于标识 4个 MBMS; 该情形下， 业务索引可为各 M BMS的业务标识。 在小区 1、 小区 3、 小区 4和小区 5分别单播或小区广播各 小区支持的 MBMS对应的业务索引。 殳小区 1、 小区 3、 小区 4和小区 5都 支持 4个 MBMS , 此时， 可在小区 1、 小区 3、 小区 4和小区 5的单播或小区 广播消息中携带相应的业务索引 A、 B、 C和 D。
图 3b为本发明 SFA内各小区传输 MBMS的差异性控制应用场景二示意图。 图 3b对应的应用场景中， 网络设备可将小区 1、 小区 2、 小区 3、 小区 4和 小区 5配置为传输和广告小区，将 SFA内所有 MBMS根据小区的共有关系进行 分组， 并以组为单位为每组业务建立一个业务索引。
例如： 殳 SFA内的包括 4个 MBMS业务： A、 B、 C和 D。 业务 A和业务 B为小区 1、 2、 3和 5的共有业务， 业务 C为小区 2、 3和 5的共有业务， 业 务 D为小区 2、 4和 5的共有业务， 因此， 可将业务 、 B、 C和 D分为 3组： AB、 C、 D, 并为这三组共有业务分别建立一个索引， 如： 索引值 1与业务组 AB对应， 索引值 2与业务组 C对应， 索引值 3与业务组 D对应。 这样， 小区 1广播的索引值为 1， 小区 2广播的索引 1、 2、 3， 小区 3广播索引值 1和 2， 小区 4广播索引值 3， 小区 5广播索引值 1、 3， 小区 6为传输小区， 不广播 相关的内容。
UE通过当前所在小区发送的小区广播消息， 可获取当前所在小区支持的 业务索引， 然后在 MCCH中查找业务索引相应的一个或多个业务的控制信息， 从这些控制信息中选出自身所需的业务， 并在 MTCH上接收相应的业务数据。
本实施例由于网络侧在 SFA内的各小区传输相同的 MBMS的控制信息，且 不同小区向 UE单播或小区广播的各小区自身支持的业务索引， 使得 UE在当 前小区中获取当前小区支持的业务索引，然后在 MCCH中查找业务索引相应的 一个或多个业务的控制信息， 从这些控制信息中选出自身所需的业务， 并在 MTCH上接收相应的业务数据。 由于不同小区向 UE单播或小区广播的业务索 引可以相同或不同，使得 UE在 SFA内的不同小区中获取的信息可以相同或不 同， 因此， 本实施例即保证了 UE接收 MBMS控制信息的分集增益， 同时又可 实现 SFA内多小区传输 MBMS的差异性控制， 且实现方法简单； 本实施例可应 用与单个 SFA内各小区传输 MBMS的差异性控制，还可应用于多个 SFA交叠处 的小区传输 MBMS的差异性控制， 因而具有较强的通用性。
图 4为本发明第三实施例提供的 MBMS控制信息的传输方法流程图。本实 施例的执行主体可为某种网络设备，即本实施例从网络侧说明 MBMS控制信息 的传输方法。 如图 4所示， 本实施例 MBMS控制信息的传输方法， 包括：
步骤 41、将用于传输 MBMS控制信息的物理多播信道（ PMCH )配置为主 P MCH和辅 PMCH。
步骤 42、 通过辅 PMCH发送 SFA内各 MBMS的控制信息； 通过主 PMCH发 送辅 PMCH上承载单频网覆盖区域（ SFA )内各小区自身相关的 MBMS的控制信 息的位置信息。
本实施例通过网络侧将物理信道进行分级， 在 SFA内的各小区的辅物理 信道传输相同的 MBMS的控制信息， 且不同小区通过对各小区主 PMCH承载的 信息进行差异性控制， 从而实现 SFA内各小区传输 MBMS的差异性控制。 由于 是对物理信道进行主辅分级处理，相对于现有的对逻辑信道 MCCH进行主辅分 级处理的方案而言， 减少了分级后的主 MCCH和辅 MCCH分别进行从逻辑信道 到传输信道、 传输信道到物理信道之间的信道映射的多级操作， 因此， 通过 对物理信道分级处理的方案，可降低 SFA各小区传输 MBMS控制信息的差异性 控制的实现复杂度。 本实施例即保证了 UE接收 MBMS控制信息的分集增益， 同时又可实现 SFA内多小区传输 MBMS的差异性控制， 且实现方法简单； 本实 施例可应用与单个 SFA内各小区传输 MBMS的差异性控制， 还可应用于多个 S FA交叠处的小区传输 MBMS的差异性控制， 因而具有较强的通用性。
图 5为本发明第四实施例提供的 MBMS控制信息的获取方法流程图。 与图 4 对应实施例的区别在于， 本实施例的执行主体可为某种用户设备， 即本实施 例从终端侧说明 MBMS控制信息的获取方法。 如图 5所示， 本实施例 MBMS控制信 息的获取方法， 包括：
步骤 51、 通过主 PMCH获取辅 PMCH上承载与当前小区相关的 MBMS的控 制信息的位置信息，主 PMCH和辅 PMCH由网络侧对用于传输 MBMS控制信息的 物理多播信道预先配置得到。
步骤 52、 在辅 PMCH上与上述位置信息相应的位置获取与当前小区相关 的 MBMS的控制信息。
本实施例通过网络侧在 SFA区内的各小区的辅物理信道传输相同的 MBMS 的控制信息， 且不同小区通过对各小区主 PMCH承载的信息进行差异性控制， 使得 UE可根据主 PMCH上承载的信息，在辅 PMCH的相应位置获取与当前小区 相关的 MBMS的控制信息。由于不同小区主 PMCH承载的信息可以相同或不同， 使得 UE在 SFA内的不同小区中获取的信息可以相同或不同， 因此， 本实施例 即保证了 UE接收 MBMS控制信息的分集增益， 同时又可实现 SFA内多小区传 输 MBMS的差异性控制， 且实现方法简单； 本实施例可应用与单个 SFA内各小 区传输 MBMS的差异性控制， 还可应用于多个 SFA交叠处的小区传输 MBMS的 差异性控制， 因而具有较强的通用性。
上述图 4和图 5对应的实施例技术方案中， 主 PMCH可进一步包括： 物理 多播控制信道 ( Phys ica l MBMS Control Channel , 简称 PMCCH )和物理多播 控制格式指示信道 ( Phys i ca l MBMS Cont ro l Forma t Indi ca tor Channe l , 简称 PMCFICH ) 。
网络设备可通过 PMCF I CH发送 PMCCH的位置信息， 如 PMCCH在多播子帧 中占用的 0FDM符号数； PMCFICH的位置信息可通过广播发送或预先配置。
网络设备可通过 PMCCH发送 SFA内各小区的小区标识（如： 无线网络临 时标识， Radio Network Temporary Ident if ier , 简称 RNTI ) 以及辅 PMCH 上承载与上述小区标识相应的 MBMS的控制信息的位置信息， 其中， 网络设备 可根据当前小区标识， 对 PMCCH承载的信息的循环冗余校验码 ( Cycl ic Red undancy Check, 简称 CRC )或数据进行扰码。 UE在 PMCFICH位置上获知 PMC CH的位置， 并采用预先获知的小区标识对 PMCCH承载的信息进行盲检得到辅 PMCH上承载与当前小区的小区 RNTI相应的 MBMS的控制信息的位置信息， 从 辅 PMCH的该位置获取当前小区支持的 MBMS的控制信息， 从这些控制信息中 选出自身所需的业务， 并从承载 MBMS业务数据的 PMCH上接收相应的业务数 据。 该情形下， 由于小区标识扰码在 PMCCH上的 CRC或数据上， 即一个小区 标识对应一个 PMCCH, 不同的小区标识对应不同的 PMCCH, PMCCH里可^载辅 PMCH的位置信息， 如果几个小区可接收的 MBMS业务完全相同， 那么这几个 小区各自有自己 PMCCH, 且有一个相同的辅 PMCH。
或者， 网络设备可通过 PMCCH发送 SFA内各小区支持的业务索引以及辅 PMCH上承载与上述业务索引相应的 MBMS 的控制信息的位置信息。 网络设备 可在 SFA内的每一小区单播或小区广播各小区自身支持的 MBMS的业务索引。 业务索引的建立方式可参见图 3a和图 3b对应实施例的记载， 不再赘述。 其 中， 网络设备可根据业务索引对 PMCCH承载的信息的 CRC或数据进行扰码。 U E 可通过单播或小区广播消息， 获取当前小区支持的业务索引； 在 PMCFICH 位置上获知 PMCCH的位置， 并采用预先获取的当前小区支持的业务索引对 PM CCH承载的信息进行盲检得到辅 PMCH上承载与当前小区支持的业务索引相应 的 MBMS的控制信息的位置信息， 从辅 PMCH的该位置获取当前小区支持的 MB MS 的控制信息， 从这些控制信息中选出自身所需的业务， 并从承载 MBMS 的 业务数据的 PMCH上接收相应的业务数据。 该情形下， 由于业务索引扰码在 P MCCH上的 CRC或数据上， 即一个业务索引对应一个 PMCCH, 不同的业务索引 对应不同的 PMCCH, PMCCH里可^载辅 PMCH的位置信息， 如果几个小区可接 收的 MBMS业务完全相同， 那么这几个小区有一个相同的 PMCCH, 且有一个相 同的辅 PMCH。
此外， 辅 PMCH上承载的 MBMS的控制信息是可以重复周期的方式进行发 送的。 每个重复周期内， 网络发送一次 MBMS的控制信息。 由于 PMCFICH占据 的资源较小且相对固定， 因而可通过 PMCF I CH发送辅 PMCH上承载的 MBMS的 控制信息是否发生改变的通知信息。 如此处理之后， UE在接 MBMS 的控制信 息之前， 可通过 PMCFICH获知当前辅 PMCH传输的 MBMS控制信息是否发生改 变， 如果当前辅 PMCH传输的 MBMS控制信息没发生改变， 所有已经在接收 MB MS业务数据的 UE可按原来的方式继续接收； 否则， UE重新检测辅 PMCH并获 取更新后的 MBMS的控制信息， 根据更新后的 MBMS的控制信息接收相应的 MB MS业务数据。 可见， 通过 PMCFICH发送辅 PMCH上承载的 MBMS的控制信息是 否发生改变的通知信息，有利于 UE及时获知 MBMS的控制信息是否发生改变， 减少 UE检测控制信道的次数， 从而有利于为 UE省电， 延长 UE电池的使用时 间。
图 6为本发明提供的 PMCH分级结构实施例示意图。如图 6所示的应用场 景中， 用于传输 MBMS的控制信息的重复周期的长度为 320ms， 包括 32个长 度为 10ms的无线帧， 无线帧的帧号依次表示为 0、 1、 2…… 30、 31 , 阴影部 分表示出的无线帧方可以 SFN方式发送 MBMS数据 (包括控制信息或业务数 据） ， 可以 SFN方式发送 MBMS数据的无线帧称为 MBSFN帧。 每个 MBSFN帧包 括 10个无线子帧， 无线子帧的帧号依次表示为 0、 1、 2…… 9， 阴影部分表 示出的无线子帧可以 SFN方式发送 MBMS数据 (包括控制信息或业务数据 ) ， 可以 SFN方式发送 MBMS数据的无线子帧称为 MBSFN子帧。 MBMS的控制信息 和 /或业务数据可依次承载在各无线帧的各 MBSFN 子帧对应的物理信道资源 中。
图 6第三行示出了各无线帧的各 MBSFN子帧对应的 PMCH资源分布示意 图。 PMCH可包括主 PMCH和辅 PMCH, 主 PMCH包括 PMCFICH和 PMCCH, 由于 P MCFICH需承载的信息较少， 因此 PMCFICH的位置信息可通过广播发送或预先 配置。 PMCFICH指示了 PMCCH占用的 OFDM符号数， 还可包括 MBMS的控制信 息是否发生改变的通知信息； PMCCH指示辅 PMCH中承载小区标识或业务索引 相应的业务的 MBMS控制信息的位置； 辅 PMCCH上承载 SFA内各 MBMS的控制 信息。
基于本发明上述图 4-图 6对应的实施例提供的方法，可通过对各小区主
PMCH (包括 PMCFICH和 PMCCH )承载的信息进行差异性控制， 从而实现 SFA 内各小区传输 MBMS的差异性控制。 例如： 如果需要将 SFA内某小区配置为传 输小区， 可不需要广播本小区提供 MBMS业务的业务索引， 使得 UE不会在该 小区获取 MBMS的控制信息， 从而将该小区的属性判定为传输小区。 可见， 通 过对物理信道分级处理的方案，可降低 SFA各小区传输 MBMS控制信息的差异 性控制的实现复杂度。本实施例即保证了 UE接收 MBMS控制信息的分集增益， 同时又可实现 SFA内多小区传输 MBMS的差异性控制， 且实现方法简单； 本实 施例可应用与单个 SFA内各小区传输 MBMS的差异性控制， 还可应用于多个 S FA交叠处的小区传输 MBMS的差异性控制， 因而具有较强的通用性。
