Description

MCCH信息的接收方法及装置、 用户设备 技术领域
本发明涉及多媒体广播多播业务 （ MBMS , Multimedia Broadcast Multicast Service )控制信道的监听技术，尤其涉及一种长期演进（ LTE, Long Term Evolution ) 系统中多媒体广播多播业务控制信道信息的接收方法及装 置， 以及用户设备。 背景技术
为了有效地利用移动网络资源， 第三代合作伙伴计划 （3GPP , 3rd Generation Partnership Project )提出了多媒体广播和多播业务 MBMS , 在移 动网络中提供一个数据源向多个用户发送数据的点到多点业务， 实现网络 资源共享， 提高网络资源尤其是宝贵的空口接口资源的利用率。 在 LTE网 络中， MBMS 技术称为演进的多媒体广播组播业务（E-MBMS , Evolved MBMS )。
现有 LTE网络中， MBMS业务的逻辑信道为多播业务信道（ MTCH, Multicast Traffic CHannel ), 每一条 MTCH对应一个 MBMS业务的会话。 多条 MTCH信道可以映射到同一条传输信道多播信道（MCH, Multicast CHannel ),一条或多条 MCH信道映射到同一条物理信道 ( PMCH, Physical Multicast CHannel ), 一条 PMCH信道由一组多播广播单频网 （MBSFN, Multicast Broadcast Single Frequency Network )子顿组成。
在现有 LTE网络中，引入了 MBSFN 区域（ area )的概念，在一个 MBSFN area中， MBMS业务采用 MBSFN方式发送， 同一个 MBSFN area中不同小 区采用相同的资源、 内容和时间同步地发送完全一样的物理信号， 以实现 接收终端的分集接收增益。 在一个 MBSFN area 中可以配置一条或多条 PMCH, —条 PMCH可以承载一个或多个 MCH, 优选的， 一条 PMCH承 载一条 MCH信道。在长期演进网络中，通知用户设备（ UE, User Equipment ) 关于某个 MBMS业务将要发生变化， 这些变化可以是会话开始、 业务承载 更新或会话停止（ session stop )等， 可以先在物理下行控制信道（PDCCH, Physical Downlink Control CHannel )上发送下行控制信息（DCI, Downlink Control Information )和 MBMS无线网络临时标志符（ M-RNTI, MBMS-Radio Network Temporary Identifier )。用户设备 UE根据 DCI中的相关信息进一步 去读取具体的 MBMS控制信道 ( MCCH, Multicast Control CHannel )消息， 这称为 MCCH通知 ( notification )机制。 3GPP Release9现有技术中， 在 SIB13( System Information Blockl 3 )中给出了 MCCH通知信息的资源配置， 包括 MCCH notification的重复因子（ notificationRepetitionCoeff ),通知帧偏 移 ( notificationOffset ), 通知子†贞位置 ( notification- subframe )。
逻辑信道 MCCH为多播控制信道， MCCH承载一个 MBSFN Area中每 条 MCH/PMCH的配置信息， 包括每个 PMCH信道配置的 MBSFN子帧配 置、调制编码方案等等。现有技术中 MCCH和 MBSFN区域是——对应的。
MCCH信道还承载业务的配置信息， 包括 MBSFN区域中业务的标识、 会话标识、 状态、 逻辑信道标识（LCID, Logical Channel ID )等信息。 UE 通过接收 MCCH获得具体一个业务的信息后，在 MTCH信道上开始接收该 业务的数据。 MCCH信道的配置信息在广播控制信道（BCCH, Broadcast Control Channel )上通过系统消息的形式发送。 如果存在多条 MCCH信道， 每一条 MCCH在广播消息中对应一组配置信息。
当 UE进入 MBSFN小区后， UE将读取 BCCH、 MCCH的消息获取 MBMS业务的配置信息， 然后在 MTCH上接收所需业务。 在现有技术中， 当 UE进入 MBSFN小区后， UE将读取小区中的所有的 MCCH, 并从中发 现希望接收的 MBMS业务是否开始；如果 UE所需的 MBMS业务没有开始， UE将监听 MCCH通知信息。 当检测到 MCCH通知信息 （MCCH change notification ), 表明 MCCH将在下一个 MCCH修改周期发生变化， 现有技 术中， MCCH通知信息只针对 session start事件， 即只有 session start事件 会触发系统侧发送 MCCH通知信息。
在对现有技术的研究和实践过程中， 发现存在以下问题： 具有 MBMS 接收能力的 UE处在重叠 MBSFN区域，区域中有 UE感兴趣接收的 MBMS 业务，现有技术要求 UE监听 MCCH通知信息，如果所需 MBMS业务已经 开始， 则 UE无法监听到相应的 MCCH通知信息， 因此可能会错过 MBMS 业务的接收。 发明内容

为使本发明的目的、 技术方案和优点更加清楚明白， 以下举实施例并 参照附图， 对本发明进一步详细说明。
本发明提供了一种在 MBSFN重叠区域中， UE接收根据当前所需的业 务接收 MCCH信息的方法， 从而保证 UE在 MBSFN重叠区域中的 MBMS 业务的正常接收。
当一个小区被两个以上的 MBSFN覆盖时， 网络侧对该小区中的每个 MBSFN area, 均会配置相应的 MCCH信道， 一条 MCCH信道对应一个 MBSFN area, 7 载所述对应 MBSFN area中发送的 MBMS业务的配置信息， 并在系统消息中发送 MCCH通知信息的配置信息。
本发明方法进一步包括以下步骤：
步骤 1、 系统侧向 UE发送重叠 MBSFN区域的 MBMS业务相关信息； 步骤 2、 UE接收上述 MBMS业务相关信息， 并确定 UE希望接收的 MBMS业务（所需 MBMS业务）已经开始， 进一步确定当前是否包含希望 接收的 MBMS业务与 MCCH的对应关系， 若包含则 UE读取所需 MBMS 业务对应的 MCCH信息；若不包含，则 UE读取区域中所有的 MCCH信息。
上面步骤 1中， 向 UE发送 MBMS业务相关信息的设备可以是广播多 播业务中心 （BM-SC , Broadcast Multicast Service Centre ) , 或者 ΜΜΕ ( Mobi l i ty Management Ent i ty , 移动管理实体）， 或者 MBM 网关 ( MBMS-GW , MBMS-GateWay ), 或者多播协调实体 （MCE , Multicast Coordination Entity ), 或者基站（eNB ), 或者其他的网元； 其中， MCE为 逻辑实体， MCE可以单独存在， 或者作为其他网元的一部分存在， 如作为 eNB的一部分。 上述基站也可以是中继 Relay或家庭基站（HeNB , Home eNodeB )。
本发明中的重叠 MBSFN区域为静态区域，即 MBSFN区域是通过操作 管理（ O&M, Operation & Management )半静态配置的， 并在 MBMS业务 发送过程中保持不变，或者 MBSFN动态区域；所述重叠区域可以是部分重 叠或者全部重叠。 所述 MBSFN 区域可以通过 MBSFN area ID指示。
步骤 1中所述 MBMS业务相关信息可以通过以下消息的至少一种发送 给 UE: 电子业务导航（ESG, Electronic Service Guide ), MCCH信息、 短 信息、 彩信、 系统消息、 无线资源控制 （RRC, Radio Resource Control )信 息；上述 MBMS业务相关信息可以是周期性发送的，同时基于事件触发的， 如 MBMS业务相关信息发生变化时发送； 其中的发送周期通过系统消息来 通知 UE。上述 MBMS业务相关信息包括但不限于以下内容的一种或几种： 区域中的 MBMS业务标识， 区域中 MBMS业务和 MCCH的对应关系， 区 域中的 MBMS业务状态， 区域中 MBMS业务的开始时间， 区域中 MBMS 业务的持续时间， 区域中 MBMS业务的结束时间， 区域中 MBMS业务的 优先级信息， 区域中 MBMS业务的计费信息， 区域中 MBMS业务的分类 信息等。

UE根据步骤 1中的 MBMS业务相关信息和已存储的 MCCH信息来判 断所需 MBMS业务已经开始。 其中， MCCH信息是 UE读取 MCCH后所 保存的 MCCH中 MBMS业务的相关信息。
UE读取所需 MBMS业务对应的 MCCH信息， 从 MCCH信息获取所 需 MBMS业务的配置信息， 实现所需 MBMS业务的接收； UE读取上述 MBSFN区域中所有 MCCH信息后， 在所读取的所有 MCCH信息中查找出 所需 MBMS业务的配置信息， 实现所需 MBMS业务的接收。
