Description

SC-MCCH的资源配置方法、系统及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种单小区多播控制信道SC-MCCH的资源配置方法、系统及装置。
背景技术
随着互联网(Internet)的迅猛发展和大屏幕多功能移动终端的普及，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，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多业务的需求，同时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)提出了多媒体广播多播业务(MBMS，Multimedia Broadcast Multicast Service)，该业务是一种从一个数据源向多个目标移动终端传送数据的技术，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业务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，移动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业务的调度与控制信令配置都是半静态的，即MBMS业务的调度信息与控制信令信息都是“长期”保持不变的，这些信息通过MBMS控制信道(MCCH，MBMS Control Channel)周期性地发送，统称为MCCH信息。演进型MBMS(eMBMS)系统可能存在多个MCCH，每个MCCH对应于不同的MBSFN区域，其中仅承载对应MBSFN区域发送的MBMS业务的控制信息。
MBMS通知消息用于描述MCCH信息是否发生变化，对于处于空闲模式(RRC Idle，Radio Resource Control Idle)或者连接模式(RRC Connected)的UE来说，只需要监听MBMS通知消息，即可知道MCCH信息是否发生变化，从而实现选择性的接收MCCH信息，即只在MCCH信息发生变化时，才接收新的MCCH信息。由于MBMS通知消息的信息量远小于MCCH信息，故用户设备选择性的接收MCCH信息，能够有效的节省资源，降低功耗。MCCH通知信息承载于指定的MBSFN子帧的PDCCH上周期性发送，相应的MBSFN子帧和发送周期通过系统消息(SIB13)指示。
在长期演进(LTE，Long Term Evolution)系统中，通知用户设备(或称终端)关于某个MBMS业务将要会话开始(session start)或者网络侧发起计数请求(counting request)，可以 先在物理下行控制信道(PDCCH，Physical Downlink Control Channel)上发送下行控制信息(DCI，Downlink Control Information)和MBMS无线网络临时标志符(M-RNTI，MBMS-Radio Network Temporary Identifier)。UE根据DCI中的相关信息进一步去读取具体的MCCH消息，这称为MCCH改变通知(notification)机制。MCCH信道上将发送具体的业务配置参数，如业务ID，业务的无线链路控制(RLC，Radio Link Control)、媒体访问控制(MAC，Media Access Control)、物理层配置参数等。
目前，在R9版本(Release 9)的LTE系统中引入了MBMS技术，并在版本10(R10，Release10)中进行了加强。在R9中，MBMS业务的控制信令与用户数据分开传输，分别称为控制面(CP，Control Plane)和用户面(UP，User Plane)。控制面通过控制业务的开始、更新和结束，来控制用户面数据的发送，实现基本的MBMS业务的发送。MBMS业务在固定大小(可以静态或半静态配置)的MBSFN(MBMS Single Frequency Network，MBMS单频网)区域中发送。在R10版本中，为了提高MBMS系统的资源利用率，方便运营商管理，对MBMS技术进行了增强。主要包括：计数和基于优先级的抢占机制。
3GPP在R13的LTE-A中提出了单小区MBMS的研究课题，其中，图1是相关技术中单小区MBMS的示意图，单小区MBMS业务在物理下行共享信道PDSCH上传输。
PDCCH是解析PDSCH数据的指示信息，因此PDCCH在时域上是在PDSCH(数据域)之前，即占用一个子帧的前1-4个符号。图2为子帧中PDCCH占3个符号的信道示意图。PDCCH中传输的信息称为下行控制信息DCI，用于指示PDSCH的资源配置，上行资源授权等信息，PDCCH尾部的CRC为16比特，采用特定的无线网络临时标识RNTI加扰，RNTI用来标识UE或特定的用途。UE对收到子帧的PDCCH进行盲捡测，盲检测是在没有先验信息的情况下，通过UE对解扰后得到的比特序列进行搜索，得到所需的控制信令。盲检测的优点是不增加额外的开销，缺点是检测复杂度较高。为了减少搜索的复杂度，TS36.213中定义了搜索空间的概念。每个UE在特定的搜索空间搜索控制信息，每个搜索空间包含一组控制信道单元(Control Channel Element，简称CCE)。LTE中的搜索空间包括公共搜索空间和UE专用的搜索空间。
在对相关技术的研究和实践过程中，发明人发现相关技术存在以下问题：单小区MBMS业务调度与多小区MBMS(MBSFN)调度有很大不同：单小区多播控制信道(Single Cell-Multicast Control Channel，简称SC-MCCH)在PDSCH上承载发送，MBSFN区域的多播控制信道MCCH在物理层广播信道(Physical broadcast channel，简称PMCH)上承载发送；目前还没有一种适用于SC-MCCH资源配置的方法。
针对相关技术中，没有适用于SC-MCCH单小区多播控制信道的资源配置方法的问题，目前尚未提出有效的解决方案。

为了更好的理解本发明，以下结合优选的实施例对本发明作进一步的解释。
本发明提供了一种单小区多播控制信道SC-MCCH的配置方法，包括：在SC-PTM小区广播消息上指示SC-MCCH的配置信息，其中，该配置信息包括：SC-MCCH修改周期MP，SC-MCCH所在时域位置信息，SC-MCCH的调制编码方案MCS之外，该配置信息还包括以下至少之一：SC-MCCH重复周期RP，SC-MCCH更新通知信息的配置信息，值标签信息。
图10是本发明优选实施例提供的单小区多播控制信道SC-MCCH的配置方法的流程图，如图10所示，包括以下步骤：
步骤801，基站eNB发送包含SC-MCCH配置信息的系统广播消息。
上述eNB是指发送单小区点到多点SC-PTM业务的小区所在eNB；上述SC-MCCH为单小区多播控制信道，SC-MCCH用于指示单小区多播业务信道SC-MTCH的相关配置信息；上述配置信息为上述SC-MCCH相关的配置信息，上述配置信息包括：SC-MCCH修改周期MP，SC-MCCH所在时域位置信息。
需要说明的是，该配置信息还可以包括以下至少之一：SC-MCCH重复周期RP，SC-MCCH更新通知信息的配置信息，值标签信息。
其中MP指示SC-MCCH可能发生变更的周期，MP＝{320ms，640ms,1280ms,2560ms,5120ms,10240ms}其中之一，RP指示一个MP中SC-MCCH重复发送的周期，RP＝{160ms,320ms,640ms,1280ms,2560ms}其中之一；SC-MCCH的时域位置包括SC-MCCH的无线帧和无线子帧配置信息，即SC-MCCH所在的无线帧和无线子帧，所述子帧为单播子帧；所述SC-MCCH的MCS是指SC-MCCH所在的子帧的MCS，一般采用MCS对应的索引号指示；
需要指出的是，上述MP和RP可以根据需要取更小的数值，但是需要满足条件：MP大于RP取值。
SC-MCCH更新通知(change notification)信息可采用以下任意一种方法指示：1)值标签，2)PDCCH中下行控制信息DCI。
如果采用值标签指示，则在指示SC-MCCH配置的系统广播消息中设置一个整数字段sc-mcchValueTag，该字段取值(0…31)，SC-MCCH每次更新，eNB设置新的sc-mcchValueTag＝原sc-mcchValueTag+1，每次UE读取SC-MCCH的配置信息时，UE保存sc-mcchValueTag的值，如果UE发现当前系统广播消息中sc-mcchValueTag的值和本地保存的sc-mcchValueTag 值不同，则说明SC-MCCH发生了更新，否则说明SC-MCCH没有变化。
如果采用DCI指示，则首先为SC-MCCH更新通知信息分配一个特定的RNTI，如SM-RNTI＝FFFC，考虑到SC-MCCH通过PDSCH传输，频域通过PDCCH调度，也需要为SC-MCCH预分配一个RNTI，如SC-MCCH RNTI＝FFFB，当然也可以SM-RNTI＝FFFB，SC-MCCH RNTI＝FFFC；在系统广播消息上的SC-MCCH更新通知信息的配置信息指示发送SC-MCCH更新通知信息的时域位置信息，如时域帧位置，和子帧索引，和一个SC-MCCH修改周期中的通知信息重复次数。
具体地，SC-MCCH更新通知消息放在时域子帧的PDCCH中的DCI上，可采用DCI format-1c，则：a)如果通知消息中只指示SC-MCCH是否更新，则采用DCI中一个比特N指示，N＝1说明SC-MCCH在下个SC-MCCH MP发生更新，N＝0说明SC-MCCH不变。b)在DCI中可以指示业务类别，如采用两个比特N指示，其中N1指示SC-MCCH是否更新，N2指示更新的业务类别，如N2＝1表示公共安全PS业务更新，N2＝0表示普通业务更新。进一步的，在DCI中可以采用两个以上比特，来指示更多的更新信息。
所述系统广播消息为现有系统广播消息，如SIB13或SIB15，或者专用于SC-PTM的新建系统广播消息。如果是SIB13，则在现有SIB13内容基础上增加上述SC-MCCH相关配置信息。
步骤802，UE接收SC-MCCH信息。
所述UE根据系统广播消息中SC-MCCH配置信息的指示，在相应的位置监听、接收所需的SC-MCCH信息，所述UE可以是开机后或小区重选/切换到新的小区后读取SC-MCCH信息，也可以是根据SC-MCCH更新通知信息的配置信息监听SC-MCCH更新通知信息。
SC-MCCH的频域调度信息通过基站在SC-MCCH所在子帧的PDCCH发送，具体地，通过PDCCH中的下行控制信息DCI发送；其中，该频域调度信息可以包括以下至少之一：SC-MCCH的频域位置信息、SC-MCCH的调制编码方案MCS。
DCI至少包括：SC-MCCH在频域的调度信息。所述UE采用预分配的SC-MCCH RNTI检测系统消息中指示的SC-MCCH子帧，如果检测成功，说明子帧中包含所需的SC-MCCH信息。
上述实施例中的UE为具有MBMS接收能力且感兴趣接收MBMS业务；UE为连接模式(RRC-Connected)或空闲模式(RRC-Idle)。
步骤803，UE判断SC-MCCH是否更新，如果是，转向步骤804，否则转向步骤805。
所述UE在系统广播消息中指示的SC-MCCH更新通知信息子帧位置检测PDCCH，所述检测是指采用SM-RNTI对子帧CRC进行掩码运算，并校验CRC，如果成功，则为所需的PDCCH，所述UE进一步读取PDCCH中DCI的内容，如果DCI中SC-MCCH更新通知信息对应的比特N＝1，说明SC-MCCH在下一个修改周期有更新，N＝0说明没有更新。
步骤804，UE读取更新的SC-MCCH信息。
所述UE根据系统广播消息中指示的SC-MCCH时域位置信息在下一个SC-MCCH修改周期一开始立即读取更新的SC-MCCH信息。
步骤805，UE根据现有的SC-MCCH信息接收所需业务。
所述UE读取现有的SC-MCCH信息中的SC-MTCH时域配置信息，并进一步根据上述时域配置信息读取所需的SC-MTCH数据。

如果采用DCI指示，则首先为SC-MCCH更新通知信息分配一个特定的RNTI，如SM-RNTI＝FFFC，考虑到SC-MCCH通过PDSCH传输，频域通过PDCCH调度，也需要为SC-MCCH预分配一个RNTI，如SC-MCCH RNTI＝FFFB，当然也可以SM-RNTI＝FFFB，SC-MCCH RNTI＝FFFC；在系统广播消息上指示发送SC-MCCH更新通知信息的时域位置信息，时域位置信息包括：时域帧周期，子帧位置，一个SC-MCCH修改周期中的通知信息重复次数。
步骤902，UE读取SC-MCCH更新通知信息的配置信息。
所述UE读取系统广播消息中的SC-MCCH更新通知信息的配置信息。
步骤903，UE监听SC-MCCH更新通知信息。
所述UE在系统广播消息指示的子帧位置监听，所述监听是指所述UE采用SM-RNTI与子帧的CRC进行掩码运算，并校验CRC，如果成功，则为所需的子帧，所述UE进一步读取子帧PDCCH中DCI的内容，其中DCI的内容即为所述SC-MCCH更新通知信息。
步骤904，UE判断SC-MCCH是否更新，如果是，转向步骤905，否则转向步骤906。
具体的SC-MCCH更新通知信息放在子帧的PDCCH中的DCI上，可采用DCI format-1c，如果通知消息中采用DCI中一个比特N指示SC-MCCH是否更新：N＝1说明SC-MCCH在下个SC-MCCH MP发生更新，N＝0说明SC-MCCH不变。
步骤905，UE读取更新后的SC-MCCH信息。
所述UE根据系统广播消息中指示的SC-MCCH时域位置信息在下一个SC-MCCH修改周期一开始立即读取更新的SC-MCCH信息。进一步的，所述UE可根据更新的SC-MCCH信息读取所需的SC-MTCH内容。
步骤906，UE根据现有SC-MCCH信息接收所需的SC-MTCH业务。
实施例二：
本实施例的场景是SC-MCCH更新通知信息采用值标签指示；图12是本发明实施例二的流程图，如图12所示，本示例包括以下步骤：
步骤1001，基站eNB通过系统广播消息指示SC-MCCH更新通知信息的值标签。
所述系统广播消息为已有的MBMS系统消息，如SIB13或SIB15.所述SC-MCCH为单小区SC-PTM对应的MCCH；所述值标签是指在指示SC-MCCH配置的系统广播消息中设置一个整数字段sc-mcchValueTag，该字段取值(0…31)，即该字段可取0-31之间所有的整数值，每次UE读取SC-MCCH的配置信息时，UE保存sc-mcchValueTag的值，如果UE发现当前系统广播消息中sc-mcchValueTag的值和本地保存的sc-mcchValueTag值不同，则说明SC-MCCH发生了更新，否则说明SC-MCCH没有变化。
步骤1002，UE接收SC-MCCH信息和SC-MCCH更新通知信息的值标签。
所述UE根据系统广播消息指示接收SC-MCCH信息并保存系统广播消息中的值标签的数值。
步骤1003，UE判断SC-MCCH是否更新，如果是，转向步骤1004，否则转向步骤1005。
所述UE根据本地保存的值标签的数值和新收到的系统广播消息中的值标签是否相同确定SC-MCCH是否更新，如果两者相同，说明SC-MCCH没有更新，如果不同，说明SC-MCCH发生了更新。
步骤1004，UE读取更新的SC-MCCH信息。
所述UE根据系统广播消息中指示的SC-MCCH时域位置信息在下一个SC-MCCH修改周期一开始立即读取更新的SC-MCCH信息。进一步的，所述UE可根据更新的SC-MCCH信息读取所需的SC-MTCH内容。
步骤1005，UE根据现有SC-MCCH信息接收所需的SC-MTCH业务。
实施例三：

步骤1105，UE判断是否为所需的业务更新，如果是，则转向步骤1106，否则转向步骤1103。
SC-MCCH更新通知信息可以采用两个或以上比特指示更多的业务更新相关信息，即在DCI中可以指示业务类别，如采用两个比特N指示，其中N1指示SC-MCCH是否更新，N2指示更新的业务类别，如N2＝1表示公共安全PS业务更新，N2＝0表示普通业务更新。进一步的，在DCI中可以采用两个以上比特，来指示更多的更新信息。
如果通过上述两个比特指示更新通知，所述UE根据N2的取值判断发生更新的业务类别，如果所述UE只对公共安全PS业务感兴趣，假设N1＝1，即SC-MCCH发生了更新，则N2＝1时表示PS业务更新，所述UE读取更新的SC-MCCH信息，N2＝0时表示非PS业务更新，UE不读取更新的SC-MCCH信息。
步骤1106，UE接收更新的SC-MCCH信息。
本步骤和步骤1105相同，这里不再赘述。
