Description

MBMS的处理方法及装置、 接收方法、 装置及系统 技术领域 本发明涉及通信领域， 具体而言， 涉及一种多媒体广播组播业务 （Multimedia Broadcast Multicast Service,简称为 MBMS)处理方法及装置、接收方法、装置及系统。 背景技术 随着互联网的迅猛发展和大屏幕多功能手机的普及， 出现了大量移动数据多媒体 业务和各种高带宽多媒体业务， 例如视频会议、 电视广播、 视频点播、 视频广告、 网 上教育、 互动游戏等。 这些移动数据多媒体业务和各种高带宽多媒体业务， 不仅满足 了移动用户不断上升的业务需求， 同时也为移动运营商带来了新的业务增长点。 这些 移动数据多媒体业务和各种高带宽多媒体业务要求多个用户能够同时接收相同数据， 与一般的数据业务相比， 具有数据量大、 持续时间长、 时延敏感等特点。 为了有效地利用移动网络资源， 第三代合作伙伴计划 （3rd Generation Partnership Project, 简称为 3GPP) 提出了多媒体广播多播业务 （Multimedia Broadcast Multicast Service, 简称为 MBMS)， MBMS业务是一种从一个数据源向多个目标传送数据的技 术， 实现了网络 （包括核心网和接入网） 资源的共享， 提高了网络资源 （尤其是空中 接口资源） 的利用率。 3GPP定义的 MBMS业务不仅能够实现纯文本低速率的消息类 的多播和广播， 还能够实现高速多媒体业务的广播和多播， 提供多种丰富的视频、 音 频和多媒体业务， 顺应了未来移动数据发展的趋势， 为第三代 （3rd Generation, 简称 为 3G) 数字通信的发展提供了更好的业务前景。 目前， 在长期演进（Long Term Evolution, 简称为 LTE)版本 9 (R9)系统中引入 了 MBMS业务， 并在 LTE版本 10 (R10) 中进行了优化。 MBMS业务在系统中承载 需要控制信令 （也称为 MBMS控制信令） 和用户数据 （也称为 MBMS业务） 的共同 传输来进行实现；其中，控制信令将会告知接收端，如终端、用户设备（User Equipment, 简称为 UE) 等相应的控制参数， 指引接收端到相应的位置去接收其感兴趣的 MBMS 业务 （即相应的用户数据）。 这种 MBMS控制信令 （控制信息， 包括： MBMS业务的 配置信息等） 在 LTE系统中是通过多播控制信道 （Multicast Control Channel, 简称为 MCCH) 来进行传输的， MBMS业务是通过多播业务信道 （Multicast Traffic Channel, 简称为 MTCH) 来进行传输的。 MCCH重复周期和修改周期的配置参数都是由网络侧 （在本申请中， 网络侧为无 线接入网（Radio Access Network,简称为 RAN)，即演进的 UTRAN (Evolved UTRAN， 简称为 E-UTRAN), 包括 eNB， MCE等， 本申请中以 eNB为例进行说明） 进行配置 的， 网路侧通过广播控制信道 （Broadcast Control Channel, 简称为 BCCH) 中的系统 信息块 13 ( System Information Blockl3，简称为 SIB13 )发送给 UE; UE通过读取 BCCH 中的 SIB13可以获知 MCCH重复周期和修改周期的配置参数， UE可以在相应的位置 上读取 MCCH信息。 相关技术中， MBMS 控制信令和 MBMS 业务是以多播广播单频网络区域 (Multicast Broadcast Single Frequency Network Area, 简称为 MBSFN Area) 来进行传 输的，在 MBSFN区域中发送控制信令和用户数据将以小区或 eNB为单位使用 MBSFN 技术进行同步发送， 目的是使得 UE在接收时可以获得相应的合并增益， MBSFN技术 需要 MBSFN区域内各个小区在相同的时频资源上发送相同的数据内容， 这样就需要 对各个小区的资源进行统一的调度和规划。 目前使用多小区 /多播协调实体 (Multi-cell/multicast Coordination Entity,简称为 MCE)网元来进行无线资源的统一调 度和规划。
LTE系统中， 小区只有一个上行载波和下行载波。 在长期演进 -高级 （Long Term Evolution-Advance, 简称为 LTE-A) 阶段， 为了提高上下行的传输速率， 一个 LTE-A 小区的上下行可以配置有多个分量载波 （Component Carrier, 简称为 CC)， 多个 CC 可以汇聚在一起形成最大 100MHz的传输带宽， UE可以在一个或多个 CC上进行数据 收发 （取决于 UE自身的能力）， 这称为载波聚合 （Carrier Aggregation, 简称为 CA)。 假设一个 LTE-A 小区有多个上下行分量载波， 那么对于小区内一个处于空闲模式的 UE， 为了简化空闲模式 UE的行为， 降低 UE的功耗， 所以空闲模式 UE总是驻留在 某一个分量载波上。 但是当 UE进入连接模式以后， 为了能让 UE以更高的速率收发 数据， 需要有一个分量载波激活过程， 对载波进行管理， 让 UE能同时在多个分量载 波上进行数据调度。 在 CA场景中， 相同的地理区域可能部署多个载波。 针对一个连接模式 （Radio Resource Control Connected,简称为 RRC Connected )UE,可以定义一个主小区 (Primary Cell, 简称为 PCell)和一个或多个辅小区 （Secondary Cell, 简称为 SCell)， 一个 UE对 应的 PCell和 SCell统称为服务小区 （Serving Cell)。 在 3GPP Rel-10中具有 MBMS和 CA能力的 UE至少可以在 PCell上接收 MBMS业务。 在 3GPP Rel-11中， UE向网络 侧上报其支持频带联合信息 （Supported Band Combination, 简称为 SBC )， 网络侧 E-UTRAN通过支持频带联合信息判断 UE接收 MBMS的能力， 即网络侧尽力为 UE 提供 SBC中指示的频率， 以实现 UE接收 MBMS业务及单播业务的需求。 图 1是相关技术的 MBMS业务发送方法按照阶段的示意图， 如图 1所示， 该方法 包括如下四个阶段： 第一个阶段为业务公告 （Service amunmcement) /系统消息， 业务公告的目的是向 用户发送 MBMS 业务的相关信息， 如临时移动组标识 （Temporary Mobile Group Identity, 简称为 TMGI)， 业务简介，业务参数，业务开始时间，业务区域标识（service area identity, 简称为 SAI)， 还可以包括 MBMS频率信息等等。 业务公告可以承载在 用户业务描述 （User Service Description, 简称为 USD)上。 业务公告属于应用层的信 息， 系统消息广播 MBMS的接入层参数， 如服务区域标识 （Service Area Identifier, 简称为 SAI)， MBMS频率等。 第二阶段为会话开始 （Session Start)。 第三阶段为 MBMS通知 （MBMS notification)。 第四阶段为数据传输 （Data transfer)。 第五阶段为会话结束 （Session Stop )。
UE可以处于空闲模式 （RRC Idle) 或者连接模式 （RRC Connected) 进行 MBMS 业务的接收； 在 3GPP Rel-11 中连接模式 UE可以向网络侧， 通过 RRC层消息上报 MBMS业务指示信息 （如： 将 MBMSInterestlndication信息配置在 RRC层消息上）， 该信息中包括其感兴趣接收的 MBMS业务 （这个感兴趣接收的 MBMS业务， 既可能 已经开始播放， 也可能还没有开始播放）所在频率， 上报的频率数不能超过 SBC中指 示的频率数。为了降低系统负载， 多个 MBMS业务可以部署在一个分量载波或者多个 分量载波上， 但一般情况下， 一个 MBMS业务部署在一个分量载波上。 针对相关技术中在多载波环境下 MBMS业务的接收效率比较低的问题，目前尚未 提出有效的解决方案。 发明内容 针对相关技术中在多载波环境下 MBMS业务的接收效率比较低的问题，本发明提 供了一种 MBMS的处理方法及装置、 接收方法、 装置及系统， 以至少解决该问题。 根据本发明的一个实施例， 提供了一种 MBMS的处理方法， 包括： 网络侧接收用 户设备 UE发送的该 UE感兴趣的 MBMS的信息； 所述网络侧根据所述信息、 该 UE 的多载波能力和该 UE的服务小区的频率激活所述感兴趣的 MBMS对应的频率或将该 UE切换到所述感兴趣的 MBMS对应的频率。 优选地， 所述网络侧根据所述信息、 该 UE的多载波能力和该 UE的服务小区的 频率激活所述感兴趣的 MBMS对应的频率或将该 UE切换到所述感兴趣的 MBMS对 应的频率包括： 所述网络侧确定出该 UE具有载波聚合 CA能力； 所述网络侧判断该 UE是否支持在服务小区中的辅小区 SCell上接收 MBMS;
