Description

发送 MBMS业务的控制信息的方法及系统和网络侧设备 技术领域
本发明涉及长期演进 ( LTE , Long Term Evolution ) 系统, 特别涉及一 种发送多媒体广播组播业务 ( MBMS , Multimedia Broadcast Multicast Service ) 的控制信息的方法及系统和网络侧设备。 背景技术
2005 年, 第三代合作伙伴计划 (3GPP , 3rd Generation Partnership Project, )启动了 LTE研究的工作组, 研究和设计第三代移动通信技术演进 的 3.9G, 即改进的 3G的下一代网络。
为了有效地利用移动网络资源, 3GPP提出了 MBMS业务, 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, 实现网络资源 共享, 提高网络资源的利用率, 尤其是宝贵的空口接口资源。 在 LTE网络 中,研究的 MBMS技术称为改进的多媒体广播组播业务( E-MBMS, Evolved MBMS )。
在频分双工(LTE FDD )和时分双工(LTE TDD ) 中, 在混合载波上, 即该载波上既有多播 ( multicast )业务, 也有单播(unicast )业务, 此时无 线帧被划分为多播单频网 MBSF 帧 (MBSF frame ) 和非 MBSFN 帧 ( None-MBSFN frame )。 其中, MBSFN frame用于承载 mulicast业务, 如: 广播业务; None-MBSFN frame, 也即单播帧 (Unicast frame ), 用于承载 unicast业务,如: 普通语音业务。 MBSFN frame中的部分子帧采用 MBSFN 发射方式,即每个 MBSFN frame中的子帧又被划分为 MBSF 子帧( MBSFN subframe )和非 MBSF 子帧( Non-MBSFN subframe ),其中, None-MBSFN frame不采用 MBSF 发射方式, 而采用 unicast发射方式。 现有 LTE技术中, MBMS业务的逻辑信道为多媒体广播组播业务点对 多点流量信道 ( MTCH ), 每一条 MTCH对应一个 MBMS业务的会话。 多 条 MTCH信道可以映射到同一条传输信道, 即多播信道(MCH ); —条或 多条 MCH信道映射到到同一条物理信道, 即物理多播信道( PMCH ), — 条 PMCH信道由一组 MBSF 子帧组成。
在现有 LTE技术中, 还引入了 MBMS单频网区域(MBSFN area ) 的 概念, 在一个 MBSFN area中, MBMS业务采用 MBSF 单频网方式发送, 同一个 MBSFN area中的所有小区均采用相同的资源、 内容和时间同步,发 送完全一样的物理信号, 以实现接收用户设备(UE ) 的接收增益。 MTCH 映射到 MCH进而映射到 PMCH, 都可以 MBSF 方式进行发送。 在一个 MBSFN area中可以配置一条或多条 PMCH信道, 一条 PMCH信道可以承 载一条或多条 MCH信道。 优选的, 一条 PMCH承载一条 MCH信道。
逻辑信道为多播控制信道( MCCH ), MCCH承载一个或多个 MBSFN Area中每条 MCH和 /或 PMCH的配置信息, 包括每个 PMCH信道配置的 MBSF 子帧配置、 调制编码方案等等。
MCCH信道还承载业务的配置信息, 包括业务的标识、 会话标识、 状 态、逻辑信道标识(LCID, logical channel ID )等信息。 UE通过接收 MCCH 获得具体一个业务的信息后, 在 MCH信道上开始接收该业务的数据。 MCCH信道的配置信息在广播信道上发送。 如果存在多条 MCCH信道, 每 一条 MCCH在广播消息中对应一组配置信息。
MBSFN Area和业务区域( SA, Service Area )的关系是: 业务区域 SA 在无线接入网络映射到一组小区, 这些小区属于一个或者多个 MBSFN area, 也就是说, 一个 SA可以映射到多个 MBSFN area。 一个小区可以属 于多个 MBSFN area, 或者属于多个业务区域, 那么在一个小区中, 可以配 置多条属于不同 MBSFN Area 的多播信道。 根据实现方式的不同, 一个 MBSFN area可以配置一条 MCCH信道, 或者多个 MBSFN area配置一条 MCCH信道, 此时属于该 MBSFN area的业务都在该对应的 MCCH信道上 指示其配置信息。 而在一个小区中,属于不同 MBSFN area的资源是互相独 立的, 也就是说, 对多个 MBSFN area, 存在多个 PMCH集, 每个 PMCH 集对应一个 MBSFN area»
一个 MBMS业务在建立时, 核心网将指示接入网设备其需要发送的业 务区域,接入网通过 SA到 MBSFN area到小区的映射关系(通过预先配置), 可以确定哪些小区发送某个业务, 考虑到一个小区可以属于多个业务区域, 则一个业务可能在一个小区中的多个 MBSFN area的 PMCH信道上进行发 送。
业务区域 SA、 MBSFN area, 小区的关系如图 1所示, 业务区 SA-1对 应 MBSFN area 1 ,业务区 SA-2对应 MBSFN area 2和 3 ,小区 A属于 MBSFN are 1和 2, 同时, 小区 A也属于 SA-1和 SA-2。
作为 MBMS业务流程的一部分, UE在接收一个业务之前, 需要接收 MBMS业务声明( announcement ) , 在现有技术中, MBMS业务声明包括业 务的标识 (TMGI )、 开始时间和媒体编码格式等内容。 网络侧设备通常通 过电子业务指南( ESD或 ESG )的格式发送此 MBMS业务声明。 所述的网 络侧设备通常为核心网设备。
当一个小区属于多个 MBSFN area, 且存在多条 MCCH, 每条 MCCH 信道对应一个或多个 MBSFN area时, UE在接收一个业务前, 需要接收这 个小区中所有的 MCCH信道,才能获知哪条 MCCH上承载了其所需接收的 MBMS业务。 并且, 考虑到在业务开始之前, MCCH信道上不可能承载任 何该业务相关的信息, 那么 UE即使接收了所有的 MCCH信道, 也不能获 知该业务将在哪个 MBSFN area中发送 , 或者说不知道哪条 MCCH信道将 承载该业务的配置信息。 发明内容

图 1为 MBSF area、 业务区域与小区之间的映射关系示意图; 图 2为本实施例中发送 MBMS业务的控制信息的系统结构示意图; 图 3为本实施例中发送 MBMS业务的控制信息的流程图。 具体实施方式
本发明的主要构思是, 网络侧设备指示 UE各区域信息和各 MCCH信 道的映射关系,优选的, 网络侧设备还可以指示各 MBMS业务的区域信息, 或 UE通过预设方式获得 MBMS业务的区域信息, 这样, UE需要接收某 一 MBMS业务时, 根据该 MBMS业务的区域信息, 以及各区域信息与各 MCCH信道的映射关系, 获得与该 MBMS业务的区域信息对应的 MCCH 信道,在该 MCCH信道上接收该 MBMS业务的配置信息。其中,各 MBMS 业务的区域信息指, 各 MBMS 业务对应的一个或多个服务区域, 或者各 MBMS 业务对应的一个或多个 MBSFN area; 网络侧通过控制消息, 如 MCCH消息或广播控制信道 BCCH消息,下发各区域信息和各 MCCH信道 的映射关系。
下面结合附图及具体实施例对本发明技术方案作进一下详细说明。 一种发送 MBMS业务的控制信息的系统, 如图 2所示, 包括网络侧设 备以及用户设备(UE ) , 其中, 网络侧设备进一步包括配置单元以及下发 单元。 下面介绍各部分的功能。
网络侧设备, 用于向 UE下发各 SA的标识信息与各 MCCH信道的映 射关系;
其中, 配置单元用于为各小区配置一个或多个 MBSFN area, 为每个 MBSFN area 配置一个或多个 SA 的标识信息, 为小区配置一条或多条 MCCH信道, 其中, 每条 MCCH信道对应一个或多个 MBSFN area, SA的 标识信息指可以唯一地标识出 S A的标识信息;
具体地, 配置单元可以为每个 MBSFN area配置一组配置信息, 其中包 括 MBSFN area对应的 MCCH信道的配置信息, 以及 MBSFN area对应的 一个或多个 S A ID , 从而可以获知该 MBSFN area所对应的 MCCH对应的 SA的标识信息。
下发单元, 用于将所述配置单元中各 SA的标识信息与各 MCCH信道 的映射关系下发给 UE; 具体地,下发单元可以通过如下任一种方式下发各 SA的标识信息与各 MCCH信道的映射关系:
1、 在系统消息中携带每个 MCCH信道的配置信息, 每个 MCCH信道 的配置信息中携带该 MCCH对应的一个或多个 SA 的标识信息, 此时该 MCCH信道的配置信息显示或隐式的指示 MCCH信道与 MBSFN area的对 应关系;
2、 在系统消息中携带每个 MBSFN area的配置信息, 显示或隐式地表 示各 MBSFN area对应的 MCCH信道的信息 , 以及该 MBSFN area对应的 一个或多个 SA的标识信息,从而指示与各 MBSF 区域分别对应的 MCCH 信道对应的 SA的标识信息;
3、 在 MCCH消息中携带当前 MCCH所对应的一个或多个 S A的标识 信息;
4、在 MCCH消息中携带该小区每个 MCCH信道对应的一个或多个 SA 的标识信息;
5、在专用信令消息中携带每个 MCCH信道对应的一个或多个 S A的标 识信息; 或者携带各 MBSFN区域的配置信息以指示与各 MBSFN区域对应 的 MCCH信道对应的 SA的标识信息,其中, MBSF 区域的配置信息包括 该 MBSFN区域对应的 MCCH信道信息以及该 MBSFN区域对应的一个或 多个 SA的标识信息; 或者携带每个 S A对应的 MBSFN area区域的信息以 指示与各 SA对应的 MCCH信道信息, 其中, MBSFN区域的信息包括该 MBSFN区域对应的 MCCH信道信息; 或者携带各 SA对应的 MCCH信道 的信息。
所述的专用信令消息是指网络侧设备通过专用控制信道或共享控制信 道发送特定 UE的信令消息。
在其他实施例中, 上述网络侧设备还用于向 UE下发各 MBMS业务对 应的 SA的标识信息, 此时, 网络侧设备还包括第二配置单元和第二下发单 元;
第二配置单元, 用于配置各 MBMS业务对应的 SA的标识信息; 第二下发单元, 可以通过 MBMS业务声明、 超链接文本协议 ( HTTP ) 或者短消息( SMS )将各 MBMS业务对应的 SA的标识信息下发给 UE。优 选的, 第二下发单元通过电子业务指南形式将各 MBMS业务对应的 SA的 标识信息发送给 UE。
上述网络侧设备是指接入网络和核心网 (包括业务网元) 的统称。 当 上述网络侧设备为两个网元设备时,网元设备一用于下发各 SA的标识信息 与各 MCCH信道的映射关系, 优选接入网网元, 如无线网络控制器、 基站 网元等。 网元设备二用于下发各 MBMS业务与 SA的映射关系, 优选核心 网网元, 尤其是业务网元, 如广播组播业务中心(BMSC )、短消息中心等。
UE, 用于接收各 SA的标识信息与各 MCCH信道的映射关系, 并结合 已获取的各 MBMS业务对应的 SA的标识信息,获取承载各 MBMS业务的 配置信息的 MCCH信道信息;
其中, UE 可以通过接收网络侧设备下发的 MBMS 业务声明、 HTTP 或者 SMS获取各 MBMS业务对应的 SA的标识信息,也可以通过预先配置 的方式获取各 MBMS业务对应的 SA的标识信息。
下面介绍上述系统传输 MBMS业务的控制信息的过程, 如图 3所示, 包括以下步骤:
步骤 301 : 网络侧设备在一个小区中配置一个或多个 MBSF area, 一 条 MCCH信道对应一个或多个 MBSF area, 即一奈 MCCH信道承载一个 或多个 MBSFN area中发送的业务的配置信息。
步骤 302: 网络侧设备通过系统消息发送各 SA的标识信息与 MCCH 的映射信息。 在本实施例中,网络侧设备通过在系统消息中携带 MBSFN area的配置 信息以指示各 SA的标识信息与 MCCH的映射信息, 其中, 网络侧设备为 每个 MBSFN area配置的配置信息包括该 MBSFN area对应的 MCCH信道 的配置信息, 以及该 MBSFN area对应的一个或多个 SA 的信息,从而指示 该 MBSFN area所对应的 MCCH对应的业务区域( S A )信息; 优选的, 采 用 SA标识 (ID ) 来指示所述业务区域的信息。
具体地, MBSFN area的配置信息的格式可以如下, 在优选实施例中, 网络侧设备可以通过系统消息 SIB12发送 MBSFN area的配置信息: MBSFN-Arealnfo:: = SEQUENCE {― MBSFN area配置信息 mbsfn-Areald INTEGER
(L.maxMBSFN-Area), - MBSFN area标识
mcch-Config SEQUENCE {
- MCCH配置信息
SA-ID-List SEQUENCE (SIZE
(1..maxS ANumberPerMBSF Area)) of SEQUENCE
SA-ID INTEGER
- 业务区域标识
步骤 303 : UE接收系统消息, 从中获取各 S A的标识信息与 MCCH的 映射信息, 并结合已获取的各 MBMS业务和 SA的映射信息, 获取承载各 MBMS业务的配置信息的 MCCH信道信息, 当 UE需要读取某一 MBMS 业务时 ,在该 MBMS业务对应的 MCCH上接收该 MBMS业务的配置信息。
其中, UE通过预先配置获知 MBMS业务和 SA的映射信息。
在其他实施例中,上述网络侧设备还可以通过 MBMS业务声明、 HTTP 或者 SMS将各 MBMS业务对应的 SA的标识信息 (即 SA ID和 TMGI的 对应关系)下发给 UE, 优选地, 通过电子业务指南(ESG或者 ESD )形式 的 MBMS业务声明下发各 MBMS业务对应的 SA的标识信息; 此时 UE通 过读取 MBMS业务声明、 HTTP或者 SMS, 获得各 MBMS业务和 SA的对 应关系,再根据系统消息中各 S A和 MCCH的映射关系, UE就可以获得承 载各 MBMS 业务的配置信息的 MCCH信道信息, 当 UE 需要读取某一 MBMS业务时, 在该 MBMS业务对应的 MCCH上接收其配置信息即可。
例如, 在图 1所示的 MBSF -Area和 SA区域的映射关系中, 小区 A 映射了 MBSFN area-1和 MBSFN area-2,这两个 MBSFN area分别对应业务 区域 SA-1和 SA-2。 如果小区 A中为 MBFSN area 1和 MBSFN area 2分别 配置一条 MCCH信道时,每个 MCCH信道承载相应的 MBSFN area中发送 的 MBMS业务的配置信息。
此时, 网络侧设备在系统消息中携带 MBSFN area 1 的配置信息和 MBSFN area 2的配置信息,其中, MBSFN area 1 的配置信息中指示 MBSFN area 1对应的 SA区域为 SA-1 ; MBSFN area 2的配置信息中指示 MBSFN area 2对应的 SA区域为 SA-2。 UE通过读取上述系统消息,即可知道 MBSFN area和 SA的对应关系。
网络侧设备还可以在业务声明中指示 UE业务 TMGI-1 的业务区域为 SA-1和 SA-3时, 如果 UE需要接收业务 TMGI-1 , 则可以根据上述系统消 息的指示可知业务 TMGI-1对应的业务区域 SA-1所对应的 MBSFN area为 MBSFN area 1 , 即 UE只需监听 MBSFN area-1的 MCCH信道即可获取业 务 TMGI- 1的配置信息, 而不必监听 MBSFN area-2对应的 MCCH信道。
上述网络侧设备是指接入网络和核心网 (包括业务网元) 的统称。 当 上述网络侧设备为两个网元设备时,网元设备一用于下发各 SA的标识信息 和各 MCCH信道的映射关系, 优选接入网网元, 如无线网络控制器、 基站 网元等。 网元设备二用于下发各 MBMS业务与 SA的映射关系, 优选核心 网网元, 尤其是业务网元, 如 BMSC、 短消息中心等。
从上述实施例可以看出,本发明的技术方案避免了 UE读取小区中每一 个 MCCH消息以寻找其所需业务的配置信息的开销, 并提高了 UE获取业 务的效率, 缩短了 UE获得业务配置信息的延时。
当然, 本发明还可有多种实施方式, 在不背离本发明精神及其实质的 但凡在本发明的精神和原则之内所作的任何修改、 等同替换、 改进, 均应 包含在本发明所附的权利要求的保护范围之内。
