Both the MBMS dedicated cell and the MBMS/unicast hybrid cell can adopt the MBSFN transmission mode. In addition, if advanced terminal receiver technology is used, the time difference of multipath propagation can be solved, thereby eliminating intra-cell interference.

本发明涉及通信技术领域, 特别涉及一种 MBMS业务的同步计 数方法和设备。 背景技术
MBMS ( Multimedia Broadcast Multicast Service, 多媒体广播组 播业务) 用于为无线小区中用户提供多媒体广播和组播服务。 LTE
( Long Term Evolution , 长期演进)系统中, 在 MBMS专用的频率层 和与非 MBMS业务共享的频率层上都能够提供 MBMS。
支持 MBMS 的 LTE 小区可以是 MBMS 专用小区也可以是 MBMS/单播混合小区。 MBMS业务可以进行单小区传输, 也可以进 行多 小 区传输。 MBMS 的多 小 区传输需要支持 MBSFN
( Multicast/Broadcast over Single-Frequency Network, 多播 /广播单频 网络)传输方式。
所谓 MBSFN是指在同一时间以相同频率在多个小区进行同步传 输。 使用这种传输方式可以节约频率资源, 提高频谱利用率。 这种技 术要求多个小区的将完全相同的内容同时发送。 这样一来, UE ( User Equipment, 用户设备, 即终端)接收机就能将多个 MBSFN 小区视 为一个大的小区。 因此, 终端不仅不会受到相邻小区传输的小区间干 扰, 而且将受益于来自多个 MBSFN小区的信号的叠加。 MBMS专用 小区和 MBMS/单播混合小区都可以采用 MBSFN传输方式。 另外, 如果利用先进的终端接收机技术还能解决多径传播的时间差问题,从 而消除小区内干扰。这种多小区同频传输所带来的分集效果还可以解 决盲区覆盖等问题, 增强接收的可靠性, 提高覆盖率。
MBMS多小区传输技术包括以下技术特点:
( 1 ) MBSFN域内 MBMS的同步传输。
( 2 ) 支持多小区 MBMS传输的合并。
( 3 ) MTCH ( Multicast Traffic Channel ,多播业务信道)和 MCCH
( Multicast Control Channel, 多播控制信道 )映射在用于 PTM ( Point To Multipoint, 点到多点)传输的 MCH ( Multicast Channel, 多播信 道)上。
( 4 )MBSFN同步区域可以半静态配置,如:通过 0&M( Operation and Maintenance, 运行和维修)。
与 MBMS传输相关的逻辑信道主要有: BCCH( Broadcast Control Channel,广播控制信道), MCCH和 MTCH,各信道的主要作用如下: ( 1 ) BCCH, 用于网络向终端广播系统信息。
对于 MBMS, BCCH中携带 MCCH的配置信息, 如: MCCH的 重复周期、 开始无线帧偏移量、 子帧位置、 MCCH修改周期、 MCCH 修改通知指示方式、 传输 MCCH 的信令 MCS ( Modulation Coding Scheme, 调制编码方式)格式等, 以便使终端可以找到 MCCH的资 源位置, BCCH中并不携带具体的 MBMS业务信息。
( 2 ) MCCH, 是一个点到多点的下行信道, 用于网络向终端传 输该 MBSFN区域中 MBMS相关的控制信息。
一个 MCCH 可以对应于一个或多个 MTCH, 即可以携带多个 MTCH的控制信息。 MCCH可包括的信息有: 该 MBSFN区域的子 帧分配和子帧分配重复周期、 PMCH ( Physical Multicast Channel , 物 理多播信道 )或 MCH的配置信息,如: MBMS session ( MBMS会话 ) 信息、 数据 MCS格式配置、 PMCH子帧位置和调度周期等。
( 3 ) MTCH, 是一个点到多点的下行信道, 用于网络向终端发 送具体的 MBMS业务数据。
网络利用 BCCH向终端指示 MCCH的配置信息,再利用 MCCH 向终端提供 ( P ) MCH信息, 终端在(P ) MCH上读取具体业务的 MSI ( MTCH Scheduling Information, MTCH调度信息;), 从而能够在 MTCH上接收 MBMS业务。
如图 1所示, 为现有技术中 MBMS业务区与 MBSFN同步区之 间的关系示意图。
MBMS 业务区由一个或多个业务标识组成, 每个标识映射至一 个或多个小区, MBMS业务区由 BM-SC ( Broadcast Multicast Service Center, 广播多播服务中心)在会话消息中携带给基站。
MBSFN区域是由同步区域内一组小区组成, 这些小区进行同步 的 MBSFN发送, MBSFN区域由 MCE ( MBMS Coordinating entity, MBMS协调实体 )根据运营商的策略进行规划, 并在 M2接口消息中 通知基站。
MBSFN 区域预留小区也属于同步区域, 该小区不进行 MBSFN 发送。
目前, 现有的 LTE MBMS逻辑架构如图 2所示, 其中, MCE作 为 RAN侧的集中节点, M2接口作为 MCE与 eNB ( evolved Node B , 演进的 Β节点, 即基站 )的逻辑接口, 可以用来传送 MBSFN的区域 标识, MCE对 MBMS业务的调度信息用以更新 MCCH配置, 转发 来自 MME的会话开始、 结束和更新消息, 同时具有 M2接口管理和 配置功能。
在现有技术中, 进行 MBMS传输前, MCE需要统计区域内对 MBMS业务感兴趣的 UE数量, 并根据统计结果进行后续的资源分 配。 如图 3所示。 因为 MCE负责 MBSFN资源的分配, 以及相应的 配置, 因此 UE对于某个 MBMS业务的接收状态应该反馈给 MCE, 由 MCE根据此信息动态或半静态调整 MBSFN的区域, 从而确保资 源的有效利用。
其中, MCE向 eNB发送的 counting请求过程的细节尚未确定, 而 eNB向 UE发送的 counting request (计数请求 )是携带在 MCCH 中的。这里的 counting request即 MBMS接收状态报告请求, counting response (计数响应) 即 MBMS接收状态4艮告上 4艮。 在实现本发明实施例的过程中 ,发明人发现现有技术至少存在以 下问题:
在 LTE系统中, eNB向 UE发送的 counting request携带在 MCCH 中, 因此, 要求 MBSFN区域内的不同小区同步传输, 以保证 MCCH 的同步传输特性。 目前虽然已经支持 MCE通知 eNB进行 UE MBMS 业务接收状态的统计机制, 但无法确保该信息在空口的同步传送。 发明内容

如背景技术所述, 在现有的技术方案中, 由于无法确保基站向各 终端设备同步发起相应的 MBMS 业务计数操作, 所以, 无法保证 MBMS业务技术的时间同步。
为了解决上述的问题, 本发明实施例给出了一种 MBMS业务的 同步计数方法, 通过 MCE通知基站相应的同步时间点, 使各基站在 相应的同步时间点对自身所服务的各终端设备进行 MBMS 业务计 数, 并由基站汇总相应的同步计数信息后反馈给 MCE, 从而, 保证 对各终端设备进行 MBMS业务计数的时间同步性。
如图 4所示, 为本发明实施例提出的一种 MBMS业务的同步计 数方法的流程示意图, 具体包括以下步骤:
步骤 S401、 MCE向各基站发送包含同步时间点信息的消息; 步骤 S402、 MCE接收各基站发送的同步计数信息。
其中,同步计数信息为各基站在同步时间点信息所对应的时间对 自身所服务的各终端设备进行 MBMS业务计数统计所得到的信息。
在实际的应用场景中, MCE可以通过以下两种方式向各基站发 送包含同步时间点信息的消息, 具体包括:
方式一、 MCE向各基站发送包含同步时间点信息的 MBMS计数 请求消息。
方式二、 MCE向各基站发送包含同步时间点信息的 MBMS过程 所对应的消息。
在此种方式下,还需要配合 MCE发给基站的 MBMS计数请求消 息才能最终实现相应的 MBMS业务计数, 因此, 在向基站包含同步 时间点信息的 MBMS过程所对应的消息之前, MCE还应向基站发送 MBMS计数请求消息。
基站只有将 MBMS计数请求消息和相应的同步时间点信息全部 接收到后, 才会进行相应的 MBMS业务计数反馈。
在具体应用场景中,应用上述哪种方式可以根据实际需要进行调 整, 具体方式的变化并不会影响本发明的保护范围。 上述过程为本发明实施例所提出的一种 MBMS业务的同步计数 方法在 MCE侧的实现流程, 下面, 本发明实施例进一步给出了一种 MBMS 业务的同步计数方法在基站侧的实现流程, 其流程示意图如 图 5所示, 具体包括以下步骤:
步骤 S501、 基站接收 MCE发送的包含同步时间点信息的消息。 步骤 S502、 基站在同步时间点信息所对应的时间向自身所服务 的各终端设备进行 MBMS业务计数统计。
步骤 S503、 基站汇总自身所服务的各终端设备的 MBMS业务计 数结果, 得到同步计数信息。
步骤 S504、 基站将同步计数信息发送给 MCE。
与前述的说明相类似, 基站接收 MCE发送的包含同步时间点信 息的消息的方式, 具体包括以下两种:
方式一、 基站接收 MCE发送的包含同步时间点信息的 MBMS 计数请求消息。
如果应用此种方式, 相当于基站同时接到了 MBMS计数请求消 息和相应的同步时间点信息, 所以, 触发相应的 MBMS业务技术操 作, 后续的处理便直接按照上述的步骤 S502至步骤 S505来执行。
方式二、 基站接收 MCE发送的包含同步时间点信息的 MBMS 过程所对应的消息。 如果应用此方式, 那么, 基站通过 MBMS过程所对应的消息接 收到了同步时间点信息, 而 MBMS计数请求消息则需要另行接收, 只有两者全部接收到的情况下, 才会完成完整的 MBMS业务计数信 息的反馈, 下面, 对于基站对于 MBMS计数请求消息以及包含同步 时间点信息的 MBMS过程所对应的消息的处理方式分别进行说明如 下:
( 1 )基站接收到 MCE发送的计数请求消息。
当基站接收到 MCE发送的计数请求消息时, 基站判断先前是否 接收到过包含同步时间点信息的 MBMS过程所对应的消息。
如果判断结果为是, 则表示基站已经接到了 MBMS计数请求消 息和相应的同步时间点信息, 所以, 触发相应的 MBMS业务计数操 作和反馈,后续的处理便直接按照上述的步骤 S502至步骤 S505来执 行。
相反, 如果判断结果为否, 则基站保存计数请求消息, 暂不进行 MBMS业务计数操作和反馈。
( 2 )基站接收到 MCE发送的包含同步时间点信息的 MBMS过 程所对应的消息。
当基站接收到 MCE发送的包含同步时间点信息的 MBMS过程所 对应的消息时, 基站判断先前是否接收到过计数请求消息;
如果判断结果为是, 则表示基站已经接到了 MBMS计数请求消 息和相应的同步时间点信息, 所以, 触发相应的 MBMS业务计数操 作和反馈,后续的处理便直接按照上述的步骤 S502至步骤 S505来执 行。
其中,判断结果为是的情况相当于前述的基站保存计数请求消息 的情况, 即基站接收到计数请求消息后, 由于暂时没有接收到包含同 步时间点信息的 MBMS过程所对应的消息, 所以, 只能暂时保存计 数请求消息, 而没有触发相应的 MBMS业务计数操作和反馈。
如果判断结果为否, 则表示基站没有接收到 MBMS计数请求消 息, 所以, 暂时不能触发 MBMS业务计数的反馈, 而只是在同步时 间点信息所对应的时间向自身所服务的各终端设备进行 MBMS业务 计数统计,并在汇总得到同步计数信息后,将同步计数信息进行保存, 即只进行 MBMS业务计数操作, 直到接收到计数请求消息后, 才会 触发 MBMS业务计数的反馈。
需要进一步指出的是, 在上述的处理过程中, MBMS 过程所对 应的消息, 具体包括 MBMS会话开始消息, 和 /或 MBMS调度消息, 具体消息类型的变化并不会影响本发明的保护范围。
在具体的实施场景中, 上述的同步时间点信息的具体表现形式, 可以为绝对的 MCCH修改周期的数量。
与现有技术相比, 本发明实施例具有以下优点:
通过应用本发明实施例的技术方案, 在 MCE发送给基站的消息 中携带同步时间点信息, 使基站在相应的同步时间点进行 MBMS业 务计数, 并由基站汇总后反馈给 MCE, 从而, 基站对其所服务的各 终端设备可以在相同的时间点进行 MBMS业务计数, 并且将 MBMS 业务计数信息向 MCE进行汇总传输,保证了 MBMS业务计数的时间 同步性, 确保了空口 MCCH内容的同步, 解决现有的技术方案中不 能保证 MBMS业务计数的时间同步的问题。 下面, 结合具体的应用场景, 对本发明实施例所提出的技术方案 进行说明。
本发明实施例所提出的技术方案的核心思想在于: 在 MCE发送 给基站的消息中引入一个时间限定信息,该时间限定信息规定了基站 在空口向终端设备发起 MBMS业务计数操作的时间。
通过这样的时间限定,保证 MBSFN区域内不同基站同时向其所 服务的终端设备发起 MBMS业务技术操作。
在实际的应用场景中, 上述的引入时间限定信息的方式是在 MCE发送给基站的 MBMS counting过程中引入同步标识。
具体的实现方法包括以下两种:
实现方法一, MCE在 MBMS counting Request消息(即前述的 MBMS计数请求消息) 中携带同步时间点信息。
如图 6 所示, 为本发明实施例所提出的一种具体应用场景下的 MBMS业务的同步计数方法的流程示意图, 具体包括以下步骤: 步骤 S601、 MCE发送 MBMS counting Request消息给各 eNB , 消息中携带同步时间点信息。
步骤 S602、 各 eNB接收到 MBMS counting Request消息后, 回 复 MBMS counting Response消息给 MCE, 响应该请求。
步骤 S603、 eNB根据需要计数的内容, 组织空口消息, 并在相 应的同步时间点向其所服务的各终端设备发送 MCCH信息。
步骤 S604、 终端设备接收 MCCH信息后, 采用相应的形式反馈 自身的信息。
步骤 S605、 eNB汇总各终端设备反馈的信息, 得到同步计数信 步骤 S606、 eNB利用独立的计数汇报过程将汇总得到的同步计 数信息发送给 MCE。
其中, 携带同步时间点信息的相应的信元格式如表 1所示: 表 1 携带同步时间点信息的信元格式

MCCH Update Time 表明同步时间点 ( MCCH更新时间)
其中, MCCH Update Time表明了进行 MBMS业务计数的同步时 间点, 在实际的应用场景中, 可以用绝对的 MCCH修改周期个数进 行表示。 实现方法二, MCE在其它 MBMS过程所对应的消息中携带同步 时间点信息。
在实际的应用场景中, 上述的其它 MBMS过程所对应的消息包 括: MBMS会话开始消息, 或 MBMS调度消息等。
为了方便说明, 本发明实施例以通过 MBMS调度消息携带同步 时间信息为例, 说明相应的处理流程, 如图 7所示, 具体包括以下步 骤:
步骤 S701、 MCE发送 MBMS counting Request消息给各 eNB。
步骤 S702、 各 eNB接收到 MBMS counting Request消息后, 回 复 MBMS counting Response消息给 MCE, 响应该请求。
与前述的步骤 S601 和步骤 S602不同的是, eNB 收到 MBMS counting request消息后, 由于还没有收到同步时间点信息, 所以, 并 不能独立组织 MCCH传输。
步骤 S703、 MCE发送 MBMS Scheduling Information消息给 eNB , 并在该 MBMS Scheduling Information消息中携带同步时间点信息。
步骤 S704、 各 eNB结合 MBMS counting Request消息所指示的 计数内容以及 MBMS Scheduling Information消息所调度的内容, 组 织空口消息, 并在相应的同步时间点发送 MCCH信息。
各 eNB 收到携带同步时间点信息的 MBMS Scheduling Information消息后, 判断先前是否收到过 MBMS counting Request消 息, 如果收到过, 则继续执行接下来的步骤 S705 至步骤 S707 的 MBMS 业务计数操作以及相应的反馈流程, 如果没有收到过, 则指 示执行步骤 S705和步骤 S706的 MBMS业务计数操作, 并将同步计 数信息在本地进行保存, 并不反馈给 MCE, 只有在接收到相应的 MBMS计数请求消息后, 如果所保存的同步计数信息符合该 MBMS 计数请求消息的要求, 才会触发相应的反馈流程。
步骤 S705、 终端设备接收 MCCH信息后, 采用相应的形式反馈 自身的信息。
步骤 S706、 eNB汇总各终端设备反馈的信息, 得到同步计数信 步骤 S707、 eNB利用独立的计数汇报过程将汇总得到的同步计 数信息发送给 MCE。
与现有技术相比, 本发明实施例具有以下优点:
通过应用本发明实施例的技术方案, 在 MCE发送给基站的消息 中携带同步时间点信息, 使基站在相应的同步时间点进行 MBMS业 务计数, 并由基站汇总后反馈给 MCE, 从而, 基站对其所服务的各 终端设备可以在相同的时间点进行 MBMS业务计数, 并且将 MBMS 业务计数信息向 MCE进行汇总传输,保证了 MBMS业务计数的时间 同步性, 确保了空口 MCCH内容的同步, 解决现有的技术方案中不 能保证 MBMS业务计数的时间同步的问题。 为了实现本发明实施例的技术方案,本发明实施例还提出了一种 MCE, 其结构示意图如图 8所示, 具体包括:
发送模块 81 , 用于向各基站发送包含同步时间点信息的消息; 接收模块 82, 用于接收各基站发送的同步计数信息, 其中, 同 步计数信息为各基站在同步时间点信息所对应的时间对自身所服务 的各终端设备进行 MBMS业务计数统计所得到的信息。

接收 MCE发送的包含同步时间点信息的 MBMS过程所对应的消 进一步的,当接收模块 91接收的 MCE发送的包含同步时间点信 息的消息具体为 MBMS过程所对应的消息时,接收模块 91还用于接 收 MCE发送的计数请求消息。
需要进一步指出的是, 上述的基站还包括:
判断模块 94, 用于在接收模块 91接收到 MCE发送的计数请求 消息之后, 判断接收模块 91 是否接收到包含同步时间点信息的 MBMS过程所对应的消息;
如果判断结果为是, 通知统计模块 92在同步时间点信息所对应 的时间向自身所服务的各终端设备进行 MBMS业务计数统计;
