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， 这一方面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（3rd Generation
Partnership Project, 简称为 3GPP )提出了 MBMS业务， 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不仅能够实现纯文本低速率的消息类组播和广播，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 3G的发展提供了更好的业务前 景。
MBMS业务的特点是业务的数据量大， 终端接收时持续时间长， 平均数 据率恒定。上述特点决定了 MBMS业务的调度，控制信令配置都是半静态的， 即 MBMS业务的调度信息， 控制信令信息都是 "长期"保持不变的， 这样每 个 MCCH (最大多点控制信道）信息的周期， 系统侧发送一个没有变化的信 息 （始终发送是因为随时都可能有新用户接入） 。 这样对于一个已经接收了 MCCH信息的终端来说，没有必要每次都去接收一个没有发生变化的 MCCH 信息， 这样会造成终端费电， 因为 MCCH信息量大，接收和解析过程比较耗 电。 于是提出了增加一个 MCCH信息更新指示信息 （英文有 MCCH change notification, 或 MBMS notification Indicator, 中文有公司称为 MBMS通知消 息、 MBMS通知信息、 MBMS通知指示或 MBMS通知指示信息等， 本文以 MBMS通知指示信息为例 ) , 用少量的物理层信息来描述 MCCH信息是否 发生了变化， 已经接入的终端只需要监听少量的信息，根据 MBMS通知指示 信息终端再去决定是否接收 MCCH信息， 起到省电的效果。 另外由于一个小区中传输的 MBMS业务可以属于不同的 MBMS业务发 送区域， 也就是 MBMS业务发送区域可能出现交叠的情况， 在 eMBMS (演 进型 MBMS ) 系统中， 一个小区中可能存在多条 MCCH, 每条 MCCH对应 一个不同的 MBMS业务发送区域， 其中仅承载对应 MBMS业务发送区域发 送的 MBMS 业务的控制信息。 MCCH 的数目取决于小区中所配业务所属 MBMS业务发生区域。 因此 MCCH的数目是可变的。 目前协议中规定一个 小区最大支持的 MBMS业务发送区域为 8个，也就是说一个小区最大支持 8 条 MCCH信道。 在 LTE中， 目前已经确定引入 MBMS通知指示信息 ,但 MBMS通知指 示信息承载在哪个物理控制信道上、如何支持多个 MCCH的通知等问题还没 有结论。
发明内容 本发明要解决的技术问题是提供一种发送、传输 MBMS寻呼指示信令的 方法及系统，提出了一种承载 MBMS通知指示信息的映射方法，可方便地实 现在系统信息 （即 MBMS通知指示信息） 中指示 MCCH的内容是否发生变 化。 为了解决上述技术问题， 本发明提供一种发送多媒体广播和组播业务

本发明的较佳实施方式 可能承载 MBMS通知指示信息的物理信道有 PDCCH( Physical Downlink
Control Channel, 物理下行控制信道）。 LTE系统中 PDCCH DCI ( Downlink Control Information, 下行控制信息） format (格式） 1A或 1C可用于承载普 通业务的寻呼消息， 其中 format 1A 能承载的信息大小为 25bit (系统带宽 5M ) 、 27bit (系统带宽 10M ) 、 28bit (系统带宽 20M ) ； format 1C能承载 的信息大小为 12bit (系统带宽 5M ) 、 13bit (系统带宽 10M ) 、 15bit (系统 带宽 20M ) 。 如果为了节省资源， 可能釆用 PDCCH DCI format 1C来承载 MBMS 通知指示信息， 如果为了进一步提高信息发送的准确率， 可以釆用 PDCCH DCI format 1 A。 本发明提供一种发送、传输 MBMS寻呼指示信令的系统及方法， 网络侧 根据寻呼指示信令的可用资源及小区支持的最大 MCCH条数为各 MCCH分 配承载 MCCH修改指示的比特资源， 并配置各 MCCH修改指示在寻呼指示 信令上的映射信息；当网络侧下发寻呼指示信令时携带配置的 MCCH对应的 MCCH修改指示。 所述寻呼指示信令的可用资源为承载 MBMS寻呼指示信 令的物理下行控制信道 PDCCH。 MBMS通知指示信息即由寻呼指示信令中 的一个或多个 MCCH修改指示组成。 寻呼指示信令也称为 MBMS寻呼信息 或 MBMS寻呼信令。 系统实施例 实施例一： 本实施例提供一种发送 MBMS寻呼指示信令的系统， 包括网络侧； 网络侧设置成：根据寻呼指示信令的可用资源及小区支持的 MCCH条数 为各 MCCH分配承载 MCCH修改指示的比特资源，并配置各 MCCH修改指 示在寻呼指示信令上的映射信息， 一个 MCCH占用一个 bit (或者多个 bit ) , 依次排列；还设置成：下发寻呼指示信令时携带配置的 MCCH对应的 MCCH 修改指示； 网络侧还设置成： 将各 MCCH修改指示所占的比特资源以及各 MCCH 修改指示在寻呼指示信令上的映射信息预设在小区的各终端中， 或通过系统 信息下发至各终端。 本实施例提供一种发送多媒体广播和组播业务（MBMS )寻呼指示信令 的装置， 应用于网络侧， 包括： 相连的配置模块和发送模块； 所述配置模块设置成： 根据寻呼指示信令的可用资源及小区支持的最大
MCCH条数为各 MCCH分配承载 MCCH修改指示的比特资源， 并配置各 MCCH修改指示在寻呼指示信令上的映射信息； 所述发送模块设置成： 下发寻呼指示信令时携带配置的 MCCH对应的 MCCH修改指示。 所述发送模块还设置成： 将各 MCCH修改指示所占的比特资源以及各 MCCH修改指示在寻呼指示信令上的映射信息预设在小区的各终端中， 或通 过系统信息下发至各终端。 网络侧釆用以下方式中的任一种配置各 MCCH修改指示在寻呼指示信 令上的映射信息：
( a )网络侧将配置的 MCCH对应的 MCCH修改指示连续填充到寻呼指 示信令上； 此时各 MCCH 修改指示在寻呼指示信令上的映射信息为各配置的 MCCH对应的 MCCH修改指示在 PDCCH上的排列顺序及起始位置；排列顺 序可以为在系统消息中配置多条 MCCH时各条 MCCH出现的先后顺序， 依 次排列表示，起始位置表示第一个 MCCH修改指示从寻呼指示信令的第几个 比特开始填充， 一般情况下起始位置从第一个 bit开始填充。 网络侧将配置的 MCCH对应的 MCCH ^ί'爹改指示填充到 PDCCH上的对 应位置， 没有配置的 MCCH对应的 MCCH修改指示所在位置填充为 0或其 他无效值；
( b ) 网络侧配置的映射信息为所有 MCCH修改指示在 PDCCH上的排 列顺序， 该排列顺序为按 MBSFN Area ID (或 MCCH ID ) 的值确定第几个 bit的对应方式； 假设每个修改指示占用 1个 bit、 起始位置从 PDCCH的第一个 bit开始 的情况下， MBSFN Area ID为 6的 MCCH的修改指示映射到 PDCCH上的 第 6个 bit。 这种情况下， 如果配置的多条 MCCH对应的 MBSFN Area ID不 是连续的， 那么在 PDCCH上的多个 MCCH修改指示也不是连续的。 网络侧将配置的 MCCH对应的 MCCH ^ί'爹改指示填充到 PDCCH上的对 应位置， 没有配置的 MCCH对应的 MCCH修改指示所在位置填充为 0或其 他无效值； 网络侧还设置成： 下发系统信息时携带配置的各 MCCH对应的 MBSFN Area ID (或 MCCH ID ) 。
( c ) 网络侧配置的映射信息为所有 MCCH修改指示在 PDCCH上的排 列顺序 , 该排列顺序为所配置的 MCCH对应的 MBMS单频网区域标识从小 到大或从大到小依次排列； 网络侧将配置的 MCCH对应的 MCCH ^ί'爹改指示填充到 PDCCH上的对 应位置， 没有配置的 MCCH对应的 MCCH修改指示所在位置填充为 0或其 他无效值； 网络侧还设置成： 下发系统信息时携带配置的各 MCCH的 MBMS单频 网区 i或标 i只。 上述网络侧可以^^站或者 MCE ( MBMS协调实体 ) 。 实施例二： 本实施例提供一种传输 MBMS 寻呼指示信令的系统， 包括网络侧及终 端； 网络侧设置成： 根据寻呼指示信令的可用资源及小区支持的最大 MCCH 条数为各 MCCH分配承载 MCCH修改指示的比特资源，并配置各 MCCH修 改指示在寻呼指示信令上的映射信息， 一个 MCCH占用一个 bit (或者多个 bit ) , 依次排列； 网络侧还设置成：下发寻呼指示信令时携带配置的 MCCH对应的 MCCH 修改指示； 以及将各 MCCH修改指示所占的比特资源以及各 MCCH修改指 示在寻呼指示信令上的映射信息预设在小区的各终端中， 或通过系统信息下 发至各终端。 终端设置成： 根据接收的各 MCCH对应的 MCCH修改指示判断配置的 各 MCCH的内容是否发生变化。 上述网络侧可以是基站或者 MCE。
方法实施例 实施例一 本实施例提供一种发送 MBMS寻呼指示信令的方法，网络侧根据寻呼指 示信令的可用资源及小区支持的最大 MCCH 条数为各 MCCH 分配承载 MCCH修改指示的比特资源， 并配置各 MCCH修改指示在寻呼指示信令上 的映射信息， 一个 MCCH占用一个 bit (或者多个 bit ) , 依次排列； 当网络 侧下发寻呼指示信令时携带配置的 MCCH对应的 MCCH修改指示。
实施例二 本实施例提供一种传输 MBMS寻呼指示信令的方法，网络侧根据寻呼指 示信令的可用资源及小区支持的最大 MCCH 条数为各 MCCH 分配承载 MCCH修改指示的比特资源， 并配置各 MCCH修改指示在寻呼指示信令上 的映射信息， 一个 MCCH占用一个 bit (或者多个 bit ) ； 当网络侧下发寻呼 指示信令时携带配置的 MCCH对应的 MCCH修改指示； 终端根据接收的各 MCCH对应的 MCCH修改指示判断配置的各 MCCH 的内容是否发生变化。 各 MCCH修改指示所占比特数（lbit或 nbit ) 可以在标准中预先设置， 也可以在下发的系统消息中配置并发送至各 UE, 本发明对此不作限制。 当寻呼指示信令的可用资源发生变化或小区支持的最大 MCCH条数发 生变化时， 网络侧重新为各 MCCH修改指示分配比特数。
以下通过几个应用实例详细介绍本发明方法 应用实例一： 网络侧将配置的 MCCH对应的 MCCH ^ί'爹改指示连续填充到 PDCCH上， 此时各 MCCH修改指示在 PDCCH上的映射信息为各配置的 MCCH对应的 MCCH修改指示在 PDCCH上的排列顺序及起始位置； 上述排列顺序可以为 在系统消息中配置多条 MCCH时各条 MCCH出现的先后顺序， 起始位置表 示第一个 MCCH修改指示从 PDCCH的第几个比特开始填充。 设配置的各 MCCH对应的 MCCH修改指示所占比特数之和为 η , 若从
PDCCH的第 m个比特开始填充配置的 MCCH修改指示， 则 PDCCH的第 m 至第 m+n - 1比特用于承载 MCCH修改指示。 若实际配置的 MCCH的条数 小于小区支持的最大条数时， PDCCH上其他没有填充 MCCH修改指示的比 特填充为 0或其他无效值。 网络侧可以将各 MCCH修改指示在 PDCCH上的映射信息预先设置在小 区的各 UE中， 也可以在下发系统信息时携带各 MCCH修改指示在 PDCCH 上的映射信息。
UE根据各 MCCH修改指示在 PDCCH上的映射信息获知 MCCH修改指 示从 PDCCH的第几个比特开始填充，以及配置的各 MCCH修改指示的排列 顺序，UE通过监听 MCCH修改指示判断对应的 MCCH的内容是否将发生改 变。
例如， 假设小区支持的 MCCH条数最多为 8条， 承载 MBMS通知指示 信息的 PDCCH DCI formatlA可承载的比特数为 25bit, 分给每条 MCCH的 寻呼指示比特为 3bit。 设系统实际配置了 5条 MCCH , 对应的 MCCH ID (与 MB SFN Area ID
——对应）分别为 1、 3、 5、 7、 8, 在系统消息中的配置列表出现的顺序为 1、 3、 5、 7、 8;若将上述 5条 MCCH对应的 MCCH修改指示连续填充到 PDCCH 上， 且 PDCCH的第 1个比特开始填充， 则填充后的效果如图 1所示， 即寻 呼指示信令的第 1至第 15个比特填充了 MCCH修改指示， 后面空白部分没 有填充 MCCH修改指示。 填充后的效果如附图 1所示。 优选地， 网络侧根据 MCCH在系统消息中配置的先后顺序将 MCCH修 改指示依次填充到 PDCCH上， 即先配置的 MCCH对应的 MCCH修改指示 排在后配置的 MCCH对应的 MCCH修改指示之前。 应用实例二： 网络侧配置的映射信息为所有 MCCH修改指示在 PDCCH上的排列顺 序， 该排列顺序为所有 MCCH对应的 MCCH标识（与 MBSFN Area ID—— 对应）从小到大（或从大到小） 、 并根据 MCCH ID的值确定对应到第几个 bit, 且各 MCCH修改指示在 PDCCH上的位置固定不变。 网络侧将配置的 MCCH对应的 MCCH ^ί'爹改指示填充到 PDCCH上的对 应位置， 没有配置的 MCCH对应的 MCCH修改指示所在位置填充为 0或其 他无效值； 这样， 无论配置的 MCCH的条数是否达到小区支持的最大条数， 各配置的 MCCH对应的 MCCH修改指示在 PDCCH上的位置均保持不变。 此时，网络侧下发系统信息时携带配置的各 MCCH的标识或——对应的 MBSFN Area ID。 网络侧可以将配置的映射信息预先设置在小区的各 UE中， 也可以在下 发系统信息时携带各 MCCH修改指示在 PDCCH上的映射信息。 UE 根据系统信息获知配置的各个 MCCH对应的标识或——对应的
MBSFN Area ID , 进而知道 MCCH对应的 MCCH修改指示在 PDCCH上的 比特位置， 通过监听这些位置上的 MCCH修改指示判断该对应的 MCCH的 内容是否将发生改变。
例如， 小区支持的最大 MCCH的条数为 8, 承载 MBMS通知指示信息 的 PDCCH的 DCI formatlA的大小为 25bit,且各 MCCH所占比特数均为 3 , 按照 MCCH ID (或——对应的 MBSFN Area ID )的值设置 MCCH修改指示 在 PDCCH上的位置， 若配置的 MCCH条数为 5 , 对应的 MCCH ID分别为 1、 3、 5、 7、 8, 配置后的效果如图 2所示， 其中阴影部分表示配置的 MCCH 对应的 MCCH修改指示在 PDCCH 上的位置， 空白部分表示没有配置的 MCCH对应的 MCCH修改指示在 PDCCH上的位置。
应用实例三： 网络侧配置的映射信息为所有 MCCH修改指示在 PDCCH上的排列顺 序 , 该排列顺序为所有 MCCH对应的 MCCH ID或 MBMS单频网区域标识 从小到大或从大到小依次排列。 网络侧将配置的 MCCH对应的 MCCH ^ί'爹改指示填充到 PDCCH上的对 应位置， 没有配置的 MCCH对应的 MCCH修改指示所在位置填充为 0或其 他无效值； 这样， 当配置的 MCCH 的条数变化时， 各 MCCH修改指示在 PDCCH上的位置可能根据新的顺序发生改变。 例如， 小区支持的最大 MCCH的条数为 8, 承载 MBMS通知指示信息 的 PDCCH的 DCI formatlA的大小为 25bit,且各 MCCH所占比特数均为 3 , 按照 MCCH对应的 MBSFN Area ID从小到大的顺序设置其在 PDCCH上的 位置，若配置的 MBSFN Area为 5个，按照 MBSFN Area ID从小到大的顺序 , 各自对应的MBSFN Area ID分别为 l、 3、 5、 7、 8, 配置后的效果如附图 3 所示， 其中阴影部分表示配置的 MCCH在 PDCCH上的位置， 空白部分表示 没有配置的 MCCH在 PDCCH上的位置。 网络侧可以将各 MCCH修改指示在 PDCCH上的映射信息预先设置在小 区的各 UE中， 也可以在下发系统信息时携带各 MCCH修改指示在 PDCCH 上的映射信息； 该映射信息指示出配置的各 MCCH对应的 MBSFN Area ID。 此时， 网络侧下发系统信息时携带配置的各 MCCH的 MBMS单频网区 i或标识。 UE根据系统信息获知配置的各个 MCCH对应的 MBSFN Area ID, 进而 获知其 MCCH修改指示在 MBMS通知指示信息上的比特位置， 通过监听该 位置上的 MCCH修改指示判断该 MCCH的内容是否将发生改变。
上述实施例中的 MBSFN Area ID和 MCCH ID也可以为其他形式的标 识，只要能唯一标识一个对应的 MBMS业务区域，且该区域对应一个 MCCH。 尽管本发明结合特定实施例进行了描述， 但是对于本领域的技术人员来 说， 可以在不背离本发明的精神或范围的情况下进行修改和变化。 这样的修 改和变化被视作在本发明的范围和附加的权利要求书范围之内。 工业实用性 本发明提供一种发送、传输 MBMS寻呼指示信令的方法及系统，可以应 用于一个小区中存在多个 MCCH的场景，并且不受 MCCH数目变化的影响。 实现简单， 终端仅需根据自己关心的 MCCH对应的 MCCH修改指示判断该 MCCH的内容是否发生变化。
