单频网上多播 /广播子帧的
获取 /配置方法及获取装置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种单频网上多播 /广播 ( Multicast/Broadcast over Single Frequency Network, 简称为 MBSFN ) 子中贞 的获取 /配置方法及获取装置。 背景技术 目前, 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是在移动 网络中提供一个数据源向多个用户发送数据的点到多点业务, 能够实现网络 资源的共享, 提高网络资源尤其是空口接口资源的利用率。 如上所述, MBMS 是一种将共享网络资源从一个数据源向多个目标传 送数据的技术, 3GPP提供的 MBMS不仅能够实现纯文本低速率的消息类组 播和广播,还能够实现高速多媒体业务的组播和广播。在长期演进( Long Term Evolution, 简称为 LTE )网络中提供的 MBMS技术称为演进的多媒体广播多 播业务 ( Evolved MBMS , 简称为 E-MBMS )„ 在 LTE频分复用 ( Frequency Division Duplex , 简称为 FDD )和 LTE时 分复用 ( Time Division Duplex , 简称为 TDD ) 中, 无线帧被划分为单频网上 多播 /广播中贞 ( Multicast/Broadcast over Single Frequency Network Frame , 简称 为 MBSFN Frame )和非 MBSFN帧( None-MBSFN Frame ),即,单播帧( Unicast Frame ); 其中, MBSFN Frame中的部分子帧釆用 MBSFN发射方式, 即: 每 个 MBSFN Frame中的子帧又被划分为 MBSFN子帧 ( MBSFN Subframe )和 非 MBSFN子帧( None-MBSFN Subframe ),即,单播子帧( Unicast Subframe ), 而 None-MBSFN Frame是指其所有子帧都不釆用 MBSFN发射方式, 而釆用 单播 ( Unicast ) 发射方式。 为了提高 E-MBMS的资源利用效率, 一个载波频率可以支持一个或多 个多播信道 ( Multicast Channel, 简称为 MCH;), 其中, 某个特定的 MCH所 分配的物理资源可以釆用特定的子帧模式 (Pattern of Subframe ), 这种子帧 模式称为 MCH 子帧分配模式 (MCH Subframe Allocation Pattern, 简称为 MSAP )0 多个属于同一 MBSFN区 i或的 MB MS业务可以映射到一个相同的 MCH 上, 其中, 每个 MBMS 业务可以承载在不同的多媒体广播多播业务多点传 输信道 (MBMS Point-to-Multipoint Traffic Channel, 简称为 MTCH ) 上, 也 就是说, 相同 MBSFN区 i或的多个 MTCH映射到一个 MCH上, 其中, 每个 MTCH 对应一个 MBMS 业务, 多个 MCH 对应不同 MBSFN 区 i或, 每个 MBSFN子帧分配方法 ( MBSFN Subframe Allocation, 简称为 MSAP ) 对应 一个 MCH, 每个 MCH可以包括一个或多个 MTCH。 图 1 是才艮据相关技术的多个 MTCH 映射到多个 MCH及 MCH分配 MBSFN Subframe的示意图,如图 1所示,在重复长度 =32个 frame中, MCH1 对应于 MBSFN Frame#2中的 #3、 #4、 #7 , MCH2对应于 MBSFN Frame#2 中的 #8和 MBSFN Frame#3中的 #3、 #4、 #7 , MCH3对应于 MBSFN Frame#3 中的 #8和 MBSFN Frame#6中的 #3、 #4、 #7、 #8 , MTCH1和 MTCH2映射 到 MCH1上, MTCH3映射到 MCH2上, MTCH4、 MTCH5和 MTCH6映射 到 MCH3上。 在 LTE网络的 FDD或者 TDD中, 无论用户设备 ( User Equipment, 简 称为 UE )是否接收 MBMS业务,都需要确定每个无线帧是否为 MBSFN帧, 以及每个 MBSFN帧中的每个子帧是否釆用了 MBSFN, 即, UE需要确定每 个 subframe是 MBSFN subframe还是 Non-MBSFN subframe , 以便确定在每 个子帧上釆用 MBSFN参考信号( MBSFN Reference Signal )还是小区特殊参 考信号 (Cell-Specific Reference Signal ) 进行信道估计, 如果 subframe 是 MBSFN subframe , 则釆用 MBSFN Reference Signal 进行信道估计, 如果 subframe是 Non-MBSFN subframe, 则釆用 Cell- Specific Reference Signal进 行信道估计。 因 匕, 演进的通用陆地无线接入网络 ( Evolved Universal Terrestrial Radio Access Network, 简称为 E-UTRAN )需要通过系统广播消息 将每个无线帧和子帧的上述信息通知给 UE, UE也需要确定每个无线帧和每 个子帧是否为 MBSFN frame和 MBSFN subframe以进行每个子帧的信道估 计。 在 LTE中, 夸 MBSFN的子帧分配分为 2个层次, 即, 无线帧级别和 子帧级别, 在无线帧级别上, 釆用周期的方式来指明一个重复周期内有哪些 无线帧是 MB SFN 帧; 在子帧级别上, 釆用 3 bit 的子帧分配 ( Subframe Allocation ), 子帧分配的取值范围是 0 ~ 7 , 从编号小的子帧开始, 依次指 明哪些子帧是 MBSFN子帧, 由于 LTE FDD和 LTE TDD在物理层结构上有 所不同, 所以 MBSFN 子帧分配也有所不同。 对于 LTE FDD, 由于子帧 #0 和 #5不能分配为 MBSFN Subframe, 因 iHl MBSFN子帧分配从子帧 #1开始依 ;^ g己。 对于 LTE FDD,在某些情况下,子帧 #4和 #9不能用于 MBSFN Subframe, 例如: 当一个小区需要在一个无线帧上配置 3~4个寻呼子帧时, 除了 #0和 #5 用于寻呼子帧以外, #4或 /和 #9也被用于寻呼子帧, 由于一个子帧不能同时 分配为 MBSFN子帧和寻呼子帧, 所以此时除了 #0和 #5 不能用于 MBSFN Subframe以夕卜, #4和 #9也不肯 用于 MBSFN Subframe, 即, ^口表 1所示, —— 个无线帧上最多有 6个子帧可以分配为 MBSFN subframe。 子帧分 S

当一个小区需要在一个无线帧上配置 1 个寻呼子帧时, iH时 #9被用于 寻呼子帧, 这样除了 #0和 #5不能用于 MBSFN Subframe以外, #9也不能用 于 MBSFN Subframe, 而子帧 #4可以用于 MBSFN Subframe。 即, 如表 2所 示, 一个无线帧上最多有 7个子帧可以分配为 MBSFN Subframe。 子帧分 S

从上述过程可以看出如下问题:
( 1 ) 当系统广播消息中配置的信息单元 "子帧分配" 的值为 6时, 即, 在一个无线帧上配置 6个 MBSFN Subframe时, 如果配置的寻呼子帧数目不 同, 则 MBSFN Subframe所占用的子帧编号不同, 即,分配了不同的 MBSFN Subframe, 这样会导致 UE在每个子帧进行信道估计时比较困难; 例如: 如 果寻呼子帧有 4个, 则 "子帧分配" = 6, MBSFN Subframe为子帧: #1 , #2, #3 , #6, #7 , #8; ^口果寻呼子中贞有 1个, 贝' J "子中贞分 g己" =7, MBSFN subframe 为子帧: #1 , #2, #3 , #4, #6, #7 , #8 , 因 匕在不同的寻呼场景下, 由于配 置不同的寻呼子帧个数, 会导致 MBSFN Subframe不相同。 ( 2 ) 由于 MBSFN Subframe 的 "子帧分配" 在多小区 /多播协调实体
( Multi-cell/multicast Coordination Entity, 简称为 MCE ) 网元上完成, 而寻 呼子帧的分配在演进节点 B ( Evolved Node B , 简称为 eNode B )完成, 因 匕 会导致两个网元之间难以进行资源协调。 发明内容 针对在不同的寻呼场景下, 由于配置不同的寻呼子帧个数, 会导致
MBSFN Subframe不 目同, 以及 MCE网元和 eNode B网元之间的资源十办调 比较困难的问题而提出本发明, 为此, 本发明旨在提供单频网上多播 /广播子 帧的获取 /配置方法和获取装置, 以解决至少上述问题之一。 根据本发明的一个方面, 提供了一种单频网上多播 /广播子帧的获取方 法, 其中, 一个无线帧包括编号为 0-9的十个子帧。 根据本发明的单频网上多播 /广播子帧的获取方法包括: 预先设置单频 网上多播 /广播 MBSFN子帧配置规则, 配置规则为配置为 MBSFN子帧的子 帧包括编号为 1 , 2, 3 , 6, 7, 8 的 6个子帧; 用户设备获取来自基站的系 统广播消息, 其中, 系统广播消息中携带有 MBSFN子帧配置信息; 用户设 备根据配置规则以及 MBSFN子帧配置信息确定被配置为 MBSFN子帧的子 帧。 优选地, MBSFN子帧配置信息是 MBSFN子帧个数信息。 优选地,用户设备根据配置规则以及 MBSFN子帧配置信息确定子帧配 置具体为: 用户设备根据 MBSFN子帧个数信息确定配置为 MSBFN子帧的 子帧个数; 用户设备根据确定的子帧个数, 确定从编号为 1的子帧开始被配 置为 MBSFN子帧, 其中, 编号为 0、 4、 5、 9的子帧不被配置为 MBSFN子 帧。 优选地, 才艮据确定的子帧个数, 从编号为 1 的子帧开始确定被配置为 MBSFN 子帧具体为: 当子帧个数为 1 时, 确定编号为 1 的子帧被配置为 MBSFN子帧; 当子帧个数为 2时,确定编号为 1、 2的子帧被配置为 MBSFN 子帧; 当子帧个数为 3时, 确定编号为 1、 2、 3的子帧被配置为 MBSFN子 帧; 当子帧个数为 4时, 确定编号为 1、 2、 3、 6的子帧被配置为 MBSFN子 帧; 当子帧个数为 5时, 确定编号为 1、 2、 3、 6、 7的子帧被配置为 MBSFN 子帧; 当子帧个数为 6时, 确定编号为 1、 2、 3、 6、 7、 8的子帧被配置为 MBSFN子帧。 才艮据本发明的一个方面, 还提供了一种单频网上多播 /广播子帧的配置 方法, 其中, 一个无线帧包括编号为 0-9的十个子帧。 才艮据本发明的单频网上多播 /广播子帧的配置方法包括: 预先设置单频 网上多播 /广播 MBSFN子帧配置规则, 其中, 配置规则为配置为 MBSFN子 帧的子帧包括编号为 1 , 2, 3 , 6, 7, 8的 6个子帧;根据配置规则进行 MBSFN 子帧配置, 并向用户设备发送系统广播消息, 其中, 系统广播消息中携带有 MB SFN子帧个数信息。 优选地, 根据配置规则进行 MBSFN子帧配置具体为: 当 MBSFN子帧 个数为 1时, ^!寻编号为 1的子帧配置为 MBSFN子帧; 当 MBSFN子帧个数 为 2时, ^寻编号为 1、 2的子帧配置为 MBSFN子帧; 当 MBSFN子帧个数为 3时, ^!寻编号为 1、 2、 3的子帧配置为 MBSFN子帧; 当 MBSFN子帧个数 为 4时, ^寻编号为 1、 2、 3、 6的子帧配置为 MBSFN子帧; 当 MBSFN子帧 个数为 5时, ^!夸编号为 1、 2、 3、 6、 7的子帧配置为 MBSFN子帧; 当 MBSFN 子帧个数为 6时, ^!寻编号为 1、 2、 3、 6、 7、 8的子帧配置为 MBSFN子帧。 才艮据本发明的一个方面, 还提供了一种单频网上多播 /广播子帧的配置 方法, 其中, 一个无线帧包括编号为 0-9的十个子帧。 才艮据本发明的单频网上多播 /广播子帧的配置方法包括: 预先设置单频 网上多播 /广播 MBSFN子帧配置规则, 才艮据配置规则, 编号为 4、 9的子帧 不被配置为 MBSFN子帧;根据配置规则进行 MBSFN子帧配置及信道估计。 优选地, 根据配置规则进行 MBSFN子帧配置具体为: 当 MBSFN子帧 个数为 1时, 将编号为 1的子帧配置为 MBSFN子帧; 当 MBSFN子帧个数 为 2时, ^寻编号为 1、 2的子帧配置为 MBSFN子帧; 当 MBSFN子帧个数为 3时, ^!寻编号为 1、 2、 3的子帧配置为 MBSFN子帧; 当 MBSFN子帧个数 为 4时, ^寻编号为 1、 2、 3、 6的子帧配置为 MBSFN子帧; 当 MBSFN子帧 个数为 5时, ^!夸编号为 1、 2、 3、 6、 7的子帧配置为 MBSFN子帧; 当 MBSFN 子帧个数为 6时, 将编号为 1、 2、 3、 6、 7、 8的子帧配置为 MBSFN子帧。 优选地,根据配置规则进行信道估计具体为: 用户设备根据接收到的系 统广播消息中的 MBSFN子帧个数信息确定 MBSFN子帧的子帧个数; 用户 设备根据确定的个数以及配置规则确定被配置为 MBSFN子帧的子帧, 并根 据确定的结果进行信道估计, 其中, 当子帧个数为 1时, 确定编号为 1的子 帧被配置为 MBSFN子帧; 当子帧个数为 2时, 确定编号为 1、 2的子帧被配 置为 MBSFN子帧; 当子帧个数为 3时, 确定编号为 1、 2、 3的子帧被配置 为 MBSFN子帧; 当子帧个数为 4时, 确定编号为 1、 2、 3、 6的子帧被配置 为 MBSFN子帧; 当子帧个数为 5时, 确定编号为 1、 2、 3、 6、 7的子帧被 配置为 MBSFN子帧; 当子帧个数为 6 时, 确定编号为 1、 2、 3、 6、 7、 8 的子帧被配置为 MBSFN子帧。 才艮据本发明的另一个方面, 还提供了一种单频网上多播 /广播子帧的获 取装置。 根据本发明的单频网上多播 /广播子帧的获取装置包括: 存储模块, 用 于存储预先设置的单频网上多播 /广播 MBSFN子帧配置规则, 其中, 配置规 则为配置为 MBSFN子帧的子帧包括编号为 1 , 2, 3 , 6, 7 , 8的 6个子帧; 获取模块, 用于获取来自基站的系统广播消息, 其中, 系统广播消息中携带 有 MBSFN子帧配置信息; 确定模块, 连接至获取模块和存储模块, 用于根 据配置规则以及 MBSFN子帧配置信息确定被配置为 MBSFN子帧的子帧。 通过本发明, 通过设置编号为 4、 9的子帧不被配置为 MBSFN子帧, 克服了在不同的寻呼场景下, 由于配置不同的寻呼子帧个数,会导致 MBSFN Subframe不相同, 以及 MCE网元和 eNode B网元之间的资源协调比较困难 的问题, 进而简 4匕了网络的配置。 附图说明 此处所说明的附图用来提供对本发明的进一步理解,构成本申请的一部 分, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的 不当限定。 在附图中: 图 1 是才艮据相关技术的多个 MTCH 映射到多个 MCH及 MCH分配
