Description

MBMS控制信令调度信息的传输方法、 系统及设备 技术领域
本发明涉及多媒体广播组播业务中信息的传输技术, 特别是涉及一种 多媒体广播组播业务控制信令调度信息的传输方法、 系统及设备。 背景技术
随着 Internet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、 广告、 网上教育、 互动游戏等等, 这些多媒体业务一方面满足 了移动用户不断上升的业务需求, 另一方面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 ) 提出了多媒体广播组播业务 (MBMS , Multimedia Broadcast Multicast Service ),该业务是一种从一个数据源向多个 目标传送数据的技术, 实现了包括核心网和接入网在内的网络资源共享, 提高了网络资源的利用率, 尤其是空中接口资源的利用率。 3GPP 定义的 MBMS不仅能够实现纯文本低速率的消息类广播和组播, 而且还能够实现 高速多媒体业务的广播和组播, 提供多种丰富的视频、 音频和多媒体业务, 这无疑顺应了未来移动数据发展的趋势, 为第三代(3G )移动通信的发展 提供了更好的业务前景。
在长期演进(LTE, Long Term Evolution ) 系统中, MBMS业务在空口 上的传输分为专用载波和混合载波两种方式, 两种传输方式的主要区别在 于: 专用载波方式, 载波仅承载 MBMS业务; 混合载波方式, 载波不仅承 载 MBMS业务, 也承载非 MBMS业务, 如单播( unicast )业务。 这样, 在 以混合载波方式承载 MBMS业务过程中, 就会存在两种类型的业务复用同 一载波的情况, 使用混合载波 载 MBMS业务和非 MBMS业务过程中, 两类业务采用时分复用 (TDM, Time-Division Multiplexing )的方式。 在这 种情况下, 如何让两类业务互不干扰、 且在传输业务过程中发挥最大的功 效是非常重要的。目前,由多播控制信道( MCCH, Multicast Control Channel ) 来承载业务的调度信息和控制信令。
现有 LTE系统中, MCCH的设计分为: 主 MCCH ( P-MCCH, Primary MCCH )用于承载主多播控制信道信令; 次 MCCH ( S-MCCH, Secondary MCCH ), 用于承载次多播控制信道信令。 P-MCCH又分为单小区模式和多 小区模式,并且多小区模式的 P-MCCH中进一步承载有 S-MCCH的调度配 置信息, 多小区模式的 P-MCCH 被映射到多播信道 ( MCH , Multicast Channel )上。 广播控制信道(BCCH, Broadcast Control Channel ) 中承载 有一个或两个 P-MCCH的调度配置信息, 也就是说, BCCH上可以指示一 个 P-MCCH, 所指示的 P-MCCH可能是单小区模式的, 也可能是多小区模 式的; BCCH上也可以指示两个 P-MCCH, 此时所指示的 P-MCCH为一个 单小区模式、 一个多小区模式, 单小区模式被传输在下行共享信道 ( DL-SCH ), 多小区模式被传输在多播信道(MCH )上。
但是, BCCH上承载的 P-MCCH的指示信息本身是什么样的; 在一个 多媒体广播组播业务单频网( MBSF , Multimedia Broadcast multicast service Single Frequency Network )区域内如何在 BCCH上指示 MBMS业务控制信 令的调度配置信息;以及终端读取 BCCH后如何获取 MBMS业务控制信令 的调度配置信息的指示信息, 现有技术中均未提供具体的实现方法。 发明内容
有鉴于此, 本发明的主要目的在于提供一种 MBMS控制信令调度信息 的传输方法、 系统及设备, 能在 BCCH上指示 MBMS业务控制信令的调度 信息, 并能使终端方便地获取相应指示信息以及 MBMS业务控制信令调度 信息。

本发明所提供的 MBMS控制信令调度信息的传输方法、 系统及设备, 在 MBSF 区域内,在 BCCH上指示 MBMS业务控制信令的无线网络临时 标识及其对应的 MBMS相关控制信令的调度配置信息的位置, 且系统在指 示的位置上发送 MBMS相关控制信令的调度配置信息及其对应的 MBMS 业务控制信令的无线网络临时标识, 相应的, 终端根据指示确定 MBMS相 关控制信令调度配置信息的位置并接收, 进而接收并解析 MBMS相关控制 信令本身。 本发明在 BCCH上仅指示发送调度配置信息的无线帧编号, 开 销较小; 并且, 可通过合理配置, 如在指示帧内的第一个子帧中发送调度 信息, 使得终端盲检的范围大大减小, 同时又不失指示的灵活度; 实现筒 单、 方便、 灵活。 附图说明
图 1为本发明指示 MBMS控制信令调度信息方法的实现流程示意图; 图 2为本发明获取 MBMS控制信令调度信息方法的实现流程示意图; 图 3为一种多小区模式下 MBMS业务的资源分配示意图。 具体实施方式
本发明的基本思想是:在 BCCH上指示 MBMS相关控制信令的调度配 置信息的位置,并在指示位置上发送 MBMS相关控制信令的调度配置信息; 相应的,终端根据 BCCH上的指示确定 MBMS相关控制信令调度配置信息 的位置, 并接收 MBMS 相关控制信令的调度配置信息, 进而接收并解析 MBMS相关控制信令本身。 本发明在 BCCH上开销较小, 且可使终端盲检 的范围大大减小, 又不失指示的灵活度。
进一步的,本发明可先设置 MBMS业务控制信令的无线网络临时标识, 相应的,在 BCCH上进一步指示 MBMS业务控制信令的无线网络临时标识 的位置, 并在指示位置上发送 MBMS业务控制信令的无线网络临时标识。
这里, 所述 MBMS相关控制信令为多播控制信道信令、 或为主多播控 制信道信令; 所述多播控制信道信令指 MCCH上承载的信令, 下文就表示 为 MCCH; 所述主多播控制信道信令指 P-MCCH上承载的信令, 下文就表 示为 P-MCCH。
本发明具体的, 可先由系统为 MBMS相关控制信令设置特定的无线网 络临时标识( RNTI, Radio Network Temporary Identifier ),记为 MCCH-RNTI。 一般无线网络临时标识是预先约定好的, 比如由协议直接规定, 这样就无 需通知终端; 当然, 也可以在使用时再设置, 这种情况下, 网络侧需通知 终端所设置的无线网络临时标识。 所设置的 MCCH-RNTI用于标识所有与 MBMS相关的控制信令, 例如 MCCH、 P-MCCH, 该 MCCH-RNTI是被终 端认知的。 其中, 所述系统指移动通信系统的网络侧。
本发明提出的 MBMS控制信令调度信息的传输方法包括两部分: 指示 MBMS控制信令调度信息的方法、 获取 MBMS控制信令调度信息的方法。 下面以 MBMS相关控制信令是 P-MCCH为例进行说明, 所述 P-MCCH可 以是多小区模式下的 P-MCCH, 也可以是单小区模式下的 P-MCCH。
图 1为本发明指示 MBMS控制信令调度信息方法的实现流程示意图, 如图 1所示, 本发明指示 MBMS控制信令调度信息的方法包括:
步骤 11 :在 BCCH上指示承载 MCCH-RNTI及其对应的 P-MCCH的调 度配置信息的位置;
这里, 所述 MCCH-RNTI由系统预先为 P-MCCH设置; 所指示的承载 MCCH-RNTI及其对应的 P-MCCH 的调度配置信息的位置, 可以是承载 MCCH- RNTI及其对应的 P-MCCH的调度配置信息所在帧的位置, 也可以 是承载 MCCH-RNTI及其对应的 P-MCCH的调度配置信息所在的发送时间 本步骤中, 系统将指示信息放置在 BCCH上发送, 指示信息用于指示 承载 MCCH-RNTI及其对应的 P-MCCH的调度配置信息所在帧的位置。 其 中,所述系统指移动通信系统的网络侧;所述帧在多小区模式下是指 MBMS 业务中系统分配的多播帧; 在单小区模式下是指承载单小区模式 MBMS业 务的帧。
本步骤中,所述发送时间窗是指:在一段时间内发送所述 MCCH-RNTI 及其对应的 P-MCCH的调度配置信息。 例如: 在指示的所在帧开始 (包含 所指示的帧)计时 6ms 内的子帧上, 系统会发送一次所述的 MCCH-RNTI 及其对应的 P-MCCH的调度配置信息。
对于多小区模式, 所述发送时间窗由多播的帧的子帧构成, 即: 计时 时只计算多播的子帧所经历的时间。 比如: 假设多小区模式下发送时间窗 为 6ms,由于每个子帧长度为 1ms,那么,发送时间窗就包括六个多播子帧, 具体到图 3所示的资源分配结构中, 假设 BCCH上所指示的无线帧为 #0, 即: 发送时间窗从多播帧 #0起始, 则发送时间窗的组成子帧为多播帧 #0中 的三个多播子帧和多播帧 #4中的三个多播子帧。 进一步的, 在具体实施时 可将发送时间窗的长度事先规定好, 这样就不需要通知终端发送时间窗的 长度, 只要告知发送时间窗的起始帧即可。
对于单小区模式, 所述发送时间窗由承载单小区模式 MBMS业务的子 帧组成。
步骤 12: 系统在所指示位置内的子帧中的约定资源上, 发送包含所述 MCCH-RNTI及其对应的 P-MCCH的调度配置信息, 并在所述子帧上发送 所述 P-MCCH信息。
本发明中, 对于多小区模式的 MBMS业务, 系统优先将 P-MCCH的 MCCH-RNTI及其 P-MCCH的调度配置信息放置在 BCCH指示的多播帧内 的第一个多播子帧上发送, 以减少终端接收 MCCH-RNTI时的盲检次数。
对于单小区模式的 MBMS业务, 系统优先将 P-MCCH的 MCCH-RNTI 及其 P-MCCH的调度配置信息放置在 BCCH指示的承载 MBMS业务的帧 内的第一个发送 MBMS业务的子帧上发送, 以减少终端接收 MCCH-RNTI 时的盲检次数。 本发明中, BCCH 中可以直接指示承载 MCCH-RNTI 及其对应的 P-MCCH 调度配置信息所在的子帧的位置, 也就是说, BCCH 指示 MCCH-RNTI及其对应的 P-MCCH调度配置信息所在帧的位置的同时, 进 一步指示其在该帧内的子帧的位置; 或者 BCCH上直接指示 MCCH-RNTI 及其对应的 P-MCCH调度配置信息所在的子帧的位置信息。 相应的, 终端 接收时只需在 BCCH 指示的子帧内检测 MCCH-RNTI 以获取对应的 P-MCCH 的调度配置信息, 再根据 P-MCCH 的调度配置信息指示接收 P-MCCH信息。
本发明中, 所述子帧内约定资源可以是在单播子帧中的前三个正交频 分复用 ( OFDM, Orthogonal Frequency Division Multiplexing )符号, 或称 为物理下行控制信道 ( PDCCH, Physical Downlink Control CHannel )上; 也可以是在多播子帧的前两个 OFDM符号, 或是多播子帧的第三个 OFDM 符号。
图 2为本发明获取 MBMS控制信令调度信息方法的实现流程示意图, 如图 2所示, 本发明获取 MBMS控制信令调度信息的方法包括:
步骤 21 : 终端读取 BCCH上 MCCH-RNTI及其对应的 P-MCCH调度 配置信息所在帧位置信息的指示信息并解析;
步骤 22: 解析后, 终端在步骤 21所述帧内的子帧中约定资源上检测直 到得到所述 MCCH-RNTI; 并获取 MCCH-RNTI对应的 P-MCCH的调度配 置信息;
如果步骤 21指示的帧为发送时间窗的起始位置, 则终端根据预先约定 的发送时间窗长度在组成发送时间窗的子帧的约定资源上检测直到得到所 述 MCCH- RNTI, 并获取 MCCH-RNTI对应的 P-MCCH的调度配置信息; 步骤 23: 根据所述 P-MCCH调度配置信息的指示, 在相应资源上接收 P-MCCH信息本身并进行解析。 下面结合附图和具体实施例进一步详细说明本发明的实现方案。
图 3为多小区模式下 MBMS业务的资源分配示意图, 图 3中, 横向是 时间轴, 纵向是频率轴, 32个无线帧构成一个修改周期, 每个无线帧包括 10个子帧, 每个子帧长度为 lms。 斜线填充部分为系统分配给 MBSF 区 域的多播资源, 用于传输 MBMS业务数据。 可以看出, 一个修改周期共分 配了八个 MBMS无线帧, 每个 MBMS无线帧中有三个多播子帧。

步骤 a32: 在 BCCH 上发送系统用来承载 MCCH-RNTI 及其对应的 P-MCCH的调度配置信息的帧的编号;
