Description

MBMS的处理方法及装置、 接收方法及设备 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 ( MBMS, Multimedia Broadcast Multicast Service )处理方法及装置、 接收 方法及设备。 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 (3GPP , 3rd Generation Partnership Project ) 提出了多媒体广播多播业务 (MBMS , Multimedia Broadcast Multicast Service ), 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(3G, 3rd Generation )数 字通信的发展提供了更好的业务前景。
目前, 在长期演进( LTE, Long Term Evolution )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(UE, User Equipment )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( MCCH, Multicast Control Channel )来进 行传输的, MBMS 业务是通过多播业务信道(MTCH, Multicast Traffic Channel ) 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 (RAN, Radio Access Network ), 即演进的 UTRAN ( E-UTRAN, Evolved 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(BCCH, Broadcast Control Channel ) 中的系统信息块 13 ( SIB13 , System Information Blockl3 ) 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 ( MBSFN Area, Multicast Broadcast Single Frequency Network 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 ( MCE , Multi-cell/multicast Coordination Entity ) 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 ( LTE-A, Long Term Evolution-Advance ) 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(CC, Component Carrier ), 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 ( CA, Carrier Aggregation )。 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 ( RRC Connected, Radio Resource Control Connected ) UE, 可以定义一个 主小区( PCell, Primary Cell )和一个或多个辅小区( SCell, Secondary Cell ), 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 ( SBC, Supported Band Combination ), 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, 所述方法包括如下四个阶段:
第一个阶段为业务公告( Service announcement ) /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( TMGI, Temporary Mobile Group Identity )、 业务简介、 业务参数、 业务开始时间、 业务区域标识( SAI, service area identity ), 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(USD, User Service Description ) 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(SAI, Service Area Identifier ), 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 )0
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,所述 MBMS业务指示信息中包括 UE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

步驟 S202: 网络侧接收 UE发送的所述 UE感兴趣的 MBMS的信息。 步驟 S204: 网络侧根据所述信息、 所述 UE的多载波能力和所述 UE 的服务小区的频率, 激活所述感兴趣的 MBMS对应的频率或将所述 UE切 换到所述感兴趣的 MBMS对应的频率。
通过上述步驟, 网络侧根据接收到的 UE发送的感兴趣的 MBMS的信 息、 所述 UE的多载波能力、 所述 UE的服务小区的频率, 激活所述感兴趣 的 MBMS对应的频率或者将所述 UE切换到所述感兴趣的 MBMS对应的频 率, 实现了在多载波环境下, 网络侧根据 UE的上报的感兴趣的 MBMS的 信息, 激活所述感兴趣的 MBMS对应的频率或者将所述 UE切换到所述频 率, 进行所述感兴趣的 MBMS的接收, 克服了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, 提高了 UE接收 MBMS的效率。
在实施时, 为了提高接收的准确率, 可以根据 UE的 CA能力以及是否 支持在 SCell上接收 MBMS来确定激活处理还是进行切换处理。 在本实施 例中, 网络侧在确定出所述 UE具有载波聚合 CA能力之后, 判断所述 UE 是否支持在服务小区中的辅小区 SCell上接收 MBMS, 在支持的情况下, 激活所述 MBMS对应的频率, 在不支持的情况下, 将 UE切换至感兴趣的 MBMS对应的频率。
在上述实施方式中, 为了提高资源的利用率, 在网络侧确定出所述 UE 具有载波聚合 CA能力, 且判断出所述 UE支持在 SCell上接收 MBMS的 情况下, 网络侧根据所述感兴趣的 MBMS对应的频率是否为所述 UE的服 务小区的频率确定是否激活 MBMS对应的频率:
在感兴趣的 MBMS对应的频率不是所述 UE的服务小区的频率时, 在 判断出所述 UE所支持的频率组合已经全部激活的情况下,网络侧可以将激 活的频率组合中的一个 SCell 进行去激活操作, 然后激活所述感兴趣的 MBMS对应的频率; 或者, 在判断出所述 UE所支持的频率组合没有被全 部激活的情况下, 网络侧将感兴趣的 MBMS对应的频率作为 SCell对应的 频率激活。
优选地, 网络侧判断所述 UE是否具有 CA能力, 可以采用直接获取或 者间接判断的方式。 例如: 网络侧接收 UE上报其是否具备支持 CA能力的 信息, 或者 UE向网络侧通过 RRC层消息上报 SupportedBandCombination 信息, 或者网络侧通过读取某个 UE 上报的 UE 能力信息中是否包括 SupportedBandCombination信息来判断,如果 UE能力指示信息中存在 SBC 或 SBC中的频率数大于 1 , 说明 UE支持 CA, 否则 UE不支持 CA。 优选 地, 所述 SBC参数可以通过 UE能力传输过程发送。 另外, 还可以根据 UE 上报的感兴趣的 MBMS的信息中是否包括多个 MBMS频点来判断所述 UE 是否具备 CA能力(上报的 MBMS频点个数小于等于 SBC中的频率个数)。
在实施时, 为了提高 UE接收 MBMS的准确率, 可以根据 UE的 CA 能力以及所述 UE所在的频率是否与感兴趣的 MBMS频率相同来确定激活 处理还是进行切换处理。 在本实施例中, 网络侧确定出所述 UE不具有 CA 能力, 然后判断所述 UE所在的频率是否与感兴趣的 MBMS频率相同, 在 判断结果为否时, 网络侧将 UE切换至感兴趣的 MBMS对应的频率。
优选地, 感兴趣的 MBMS的信息包括以下至少之一: 感兴趣的 MBMS 所在的频率、 所述感兴趣的 MBMS是否比单播业务的优先级高。 所述优选 实施例中提供多种信息组合, 可以提高网络侧确定所述 MBMS频率信息的 准确性。 比较优的, 感兴趣的 MBMS的频率为通过系统消息或应用层消息 确定的感兴趣的 MBMS通过多播广播单频网络( MBSFN )发送的频率。 所 述感兴趣的 MBMS是否比单播业务的优先级高可以用一比特指示, 当发生 网络拥塞时, 优先考虑优先级高的业务接收。
为了降低信令的负荷, 所述感兴趣的 MBMS的信息还包括: 用于指示 所述 UE是否支持在辅小区 SCell上接收 MBMS。

步驟 S306: UE接收感兴趣的 MBMS。 优选地, 感兴趣的 MBMS的信息包括以下至少之一: 感兴趣的 MBMS 所在的频率、 所述感兴趣的 MBMS是否比单播业务的优先级高。 所述优选 实施例中提供多种信息组合, 可以提高网络侧确定所述 MBMS频率信息的 准确性。 比较优的, 感兴趣的 MBMS的频率为通过系统消息或应用层消息 确定的感兴趣的 MBMS通过多播广播单频网络(MBSFN )发送的频率。
为了降低信令的负荷, 所述感兴趣的 MBMS的信息还包括: 用于指示 所述 UE是否支持在辅小区 SCell上接收 MBMS。

在本步驟中, 所述 UE为具有 MBMS接收能力的 UE, 且所述 UE处于 连接模式。
优选地, 本步驟中的网络侧可以为无线接入网( Radio Access Network, 简称为 RAN ) , 即演进的 UTRAN ( Evolved UTRAN , 简称为 E-UTRAN ) , 比较优的, 所述网络侧包括 eNB。
优选地, 本步驟中的感兴趣的 MBMS业务是指: UE正在接收或感兴 趣接收的 MBMS业务, 其中, 感兴趣接收的 MBMS业务是指: 所述业务 (本申请中的业务是指 MBMS业务)还没有开始, 但 UE可以通过系统消 息, 或应用层消息等获得指示信息, 例如: 可以知道所述业务何时开始的 信息。
优选地, MBMS业务指示信息(本申请中也称为指示信息)包括 MBMS 业务所在的频率信息(本申请中 MBMS业务所在的频率信息也称为 MBMS 频点或 MBMS频率;), 所述 MBMS业务指示信息还可以包括 MBMS频率 的物理小区标识(Physical Cell ID, 简称为 PCI )、 频点信息、 带宽信息、 分量载波索引信息的一种或多种。 比较优的, 所述 MBMS业务指示信息还 可以包括所述 UE是否支持在 PCell之外的服务小区(即 SCell )接收 MBMS 业务, 例如: 可以用 1比特信息指示是否支持在 SCell上接收 MBMS业务。

优选地, 本优选实施例中激活感兴趣的 MBMS频率的步驟可以为: 感 兴趣的 MBMS频率可以和 PCell作为 SBC指示的组合, 否则需要将 UE切 换到感兴趣的 MBMS频率; 在 SBC中不仅包括 UE支持的频率数, 还包括 不同频率的组合方式, 如带内 /带外频率的组合, 这里的带内 /带外频率是指 连续 /非连续频率。
步驟 S810: 网络侧切换 UE到感兴趣的 MBMS频率, 流程结束。

步驟 S1006: UE在感兴趣的 MBMS频率接收 MBMS业务,流程结束。 需要说明的是, UE 目前所在的频率即为 UE感兴趣的 MBMS频率, 则 UE在当前频率接收 MBMS业务。 步驟 S1008: 网络侧将 UE切换到感兴趣的 MBMS频率小区, UE在 MBMS频率接收 MBMS业务, 当前处理流程结束。
优选地, UE可以在原服务小区释放 RRC连接, 进入感兴趣的 MBMS 频率, 进行 MBMS业务的接收; 其中, UE在切换后的 MBMS频率可以为 空闲模式, 也可以为连接模式。

步驟 S1104: 判断感兴趣的 MBMS频率是否为服务小区, 如果判断结 果是, 执行步驟 S1106, 否则执行步驟 S1108。优选地, 服务小区包括 PCell 和 SCell。
步驟 S1106: 在服务小区接收 MBMS, 流程结束。
需要说明的是, 感兴趣的 MBMS频率和服务小区中的频率相同, 则在 服务小区接收 MBMS业务; 如果在服务小区有单播业务, 考虑到 MBMS 业务在 MBSFN 资源上发送, UE 可以采用时分复用的方式接收单播和 MBMS业务, 或者 UE停止接收单播业务开始接收 MBMS业务。
步驟 S1108: 判断 UE支持的频率组合是否已全部激活, 如果判断结果 为是, 执行步驟 S1110, 否则执行步驟 S1112。
需要说明的是, 本步驟中的全部激活是指根据 SBC的指示, 网络侧已 经激活了 UE所支持的频率组合, 例如 SBC支持 3个 CC的组合, 网络侧 激活了 3个 CC (包括一个 PCC和 2个 SCC )。
步驟 S1110:网络侧去激活其中一个 SCell,激活感兴趣的 MBMS频率, UE接收 MBMS, 流程结束。
需要说明的是, 去激活或激活是指网络侧通过 RRC 信令(如 RRCConnectionReconfiguration过程)进行减少或增加 SCell的过程。
步驟 S1112: 网络侧激活感兴趣的 MBMS频率, UE接收 MBMS, 流 程结束。
优选地, 在 UE支持的频率未全部激活的情况下, 网络侧将 UE感兴趣 的 MBMS频率作为 SCell激活。

步驟 S1204: 判断 UE的 PCell是否在感兴趣的 MBMS频率,如果判断 结果为是, 执行步驟 S1206, 否则执行步驟 S1208。

步驟 S1206: UE在感兴趣的 MBMS频率接收 MBMS业务,流程结束。 在本步驟中, UE在 PCell上接收 MBMS业务。
步驟 S1208: 网络侧将 UE切换到感兴趣的 MBMS频率小区, UE在 MBMS载波小区接收 MBMS业务, 当前处理流程结束。 需要说明的是, UE在原服务小区释放 RRC连接,进入感兴趣的 MBMS 频率, 进行 MBMS业务的接收; 其中, UE在切换后的 MBMS频率可以为 空闲模式, 也可以为连接模式。
