Since the information amount of the MBMS notification message is much smaller than the MCCH information, the user equipment selectively receives the MCCH information, which can effectively save resources and reduce power consumption.
  • the MCCH notification information is periodically transmitted on a physical downlink control channel (PDCCH, Physical Downlink Control Channel) of the specified MBSFN subframe, and the corresponding MBSFN subframe and transmission period are indicated by a system message (System Information Block (SIB) 13).

  • the CP controls the transmission of UP user data by controlling the start, update, and end of the service, and implements basic MBMS service transmission.

Description

一种实现业务调度的方法、系统、基站及用户设备 技术领域
本申请涉及但不限于移动通信系统。
背景技术
随着Internet技术的快速发展和大屏幕多功能移动终端的大量普及，移动数据多媒体业务和各种高带宽多媒体业务得到的大范围的应用推广，比较常见的有视频会议、电视广播、视频点播、广告、网上教育和互动游戏等，这些多媒体业务的应用推广满足了移动用户的应用需求，也促进了移动运营商新的业务增长。这些多媒体业务存在要求多个用户能够同时接收相同数据，因此，与一般的数据业务相比，具有数据量大、持续时间长和时延敏感等特点。
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)，MBMS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，而且还能够实现多媒体业务的广播和组播，为多媒体业务提供多种丰富的视频、音频，这无疑顺应了未来移动数据发展的趋势，为移动通信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对应于不同的多媒体广播单频网(MBSFN，Multicast Broadcastg Single Frequency Network)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)的用户设备(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子帧的物理下行控制信道(PDCCH，Physical Downlink Control Channel)上周期性发送，相应的MBSFN子帧和发送周期通过系统消息(系统信息块(SIB)13)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PDCCH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中的信息选择读取具体的MCCH消息，这称为MCCH改变通知(notification)机制。MCCH消息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)。CP通过控制业务的开始、更新和结束来控制UP用户数据的发送，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区域中发送。MBMS业务调度信息通过MBSFN子帧上的多播信道调度信息(MSI，MCH Scheduling Information)指示，MBMS业务在时域复用。
3GPP在R13版本的LTE-A中提出了单小区MBMS的研究课题，其中单小区MBMS业务在PDSCH上传输，称为单小区点到多点(SC-PTM，Single Cell-Point To Multipoint)。
PDCCH是解析物理下行共享信道(PDSCH，Physical Downlink Share Channel)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1为相关技术子帧中PDCCH占3个符号的信道示意图，如图1所示，其中，横格纹图框代表PDSCH，竖格纹代表PDCCH，左斜线格纹代表控制格式指示信道(PCFICH)，右斜线格纹代表物理混合自动重传指示信道(PHICH)，黑底条框代表参考信号(RS)，白底条框代表物理广播信道(PBCH)；PDCCH中发送的信息DCI用于指示PDSCH的资源配置和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进行盲检测(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令，每个搜索空间包含一组控制信道单元(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。
对上述业务调度应用中，存在以下问题：单小区MBMS业务调度与多小区MBMS(通过MBSFN进行业务调度指示)调度有很大不同：PDSCH的调度信息在PDCCH上传输，PDSCH可采用时频复用，物理层广播信道(PMCH)的调度信息在MSI上传输，PMCH只能时域复用；因此不能在单小区MBMS调度中采用多小区MBMS调度的方法，考虑MBMS业务与单播业务的差异，在每个子帧的PDCCH上动态调度MBMS业务也不适合，目前，没有一种适合单小区传输的MBMS业务调度方法。
