Description

数据传输的方法、装置及系统 技术领域
本发明涉及无线通信技术领域，具体涉及数据传输的方法、装置及系统。
背景技术
为了传输多媒体广播多播业务(multimedia broadcast multicast service，简称MBMS)，在长期演进(Long Term Evolution，简称LTE)系统中引入了多媒体广播多播单频网(multimedia broadcast multicast service single frequency network，简称MBSFN)技术。所谓的MBSFN技术，是在多个小区使用相同的时频资源、使用相同的编码调制方式、同步传输相同的多媒体业务数据。从用户设备(user equipment，简称UE)的角度来看，MBSFN信号就是从单个小区发出来的经过多径传播的无线信号。采用MBSFN技术能够有效的增强小区边缘的接收信号强度，消除小区间干扰，提升MBMS的覆盖。
在LTE系统中，将传输相同的多媒体内容、由一个或多个小区组成的物理区域称为MBMSN区域，一个MBSFN区域内的多个小区之间的无线资源协调与分配由多小区多播协作实体(multi-cell/multicast coordination entity，简称MCE)实现。
为了简化系统设计，传输MBMS数据是以子帧为粒度的，对于某个子帧，或者全部用于MBMS数据的传输，或者全部用于非MBMS数据的传输。用于传输MBMS数据的子帧称为MBSFN子帧。
在LTE系统中，UE在空闲模式下使用非连续接收(discontinuous reception，简称DRX)以减少功率消耗。基站给UE发送寻呼消息只能在特定的子帧上发送，这些可能发送寻呼消息的子帧称为寻呼时机(paging  occasion，简称PO)。每个小区可能的PO由寻呼参数nB和非连续接收周期(discontinuous reception cycle，简称DRX Cycle或T)确定，例如，当nB＝4T时，可能的PO对应的子帧个数达到最大，对于频分双工(Frequency Division Duplex，简称FDD)系统，可能的PO为子帧0、子帧4、子帧5和子帧9；对于时分双工(Time Division Duplex，简称TDD)系统，可能的PO为子帧0、子帧1、子帧5和子帧6。更详细的有关寻呼的描述可以参考第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)的36.304V13.1.0(2016-03)协议中的第7章。
当前的LTE系统中，MBSFN子帧最多只能使用60％的无线资源，当MBMS数据增多的时候，无法给MBMS配置更多的无线资源。
发明内容
本发明实施例提供了一种数据传输的方法、装置及系统，以实现给MBMS配置更多的无线资源，从而增加MBMS容量。
本发明实施例具体可以通过如下技术方案实现：
第一方面，本发明的实施例提供了一种数据传输的方法，该方法包括：接收来自MCE的第一消息，该第一消息包括第一指示，该第一指示用于指示扩展的MBSFN资源的时频位置，该第一消息还包括小区标识和MBSFN区域标识中的至少一个，其中，扩展的MBSFN资源为MBSFN子帧集合之外的用于传输MBMS数据的时频资源；向UE发送第二消息，该第二消息包括第二指示，该第二指示用于指示该扩展的MBSFN资源的时频位置。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有 作出创造性劳动的前提下所获得的所有其它实施例，都应属于本发明保护的范围。
图1为本发明实施例提供的一种数据传输方法示意图。当MBMS的业务量增大，当前MBMS子帧集合中的无线资源不足以承载的时候，可以按照如下方法对MBSFN子帧进行扩展，以增加MBMS可用的无线资源。
101，MCE确定扩展的MBSFN资源，用于传输MBMS数据。
其中，扩展的MBSFN资源是指MBSFN子帧集合之外的用于传输MBMS数据的时频资源。其中，MBSFN子帧集合是指在现有的协议中能够用于传输MBMS数据的子帧的集合，根据3GPP的36.331 V13.1.0(2016-03)协议中6.3.7节的描述：对于FDD系统，MBSFN子帧集合为子帧1、子帧2、子帧3、子帧6、子帧7和子帧8；对于TDD系统，MBSFN子帧集合为子帧3、子帧4、子帧7、子帧8和子帧9。
该扩展的MBSFN资源包括MBMS数据独享的子帧资源和MBMS数据与其它单播或广播数据共享的子帧资源中的至少一种。可以理解的是，在该扩展的MBSFN资源为MBMS数据独享的子帧资源的情况下，该扩展的MBSFN资源的子帧内可用于传输数据的所有时频资源都用于传输MBMS数据，在该扩展的MBSFN资源为MBMS数据与其它单播或广播数据共享的子帧资源的情况下，该扩展的MBSFN资源的子帧内可用于传输数据的部分时频资源用于传输MBMS数据。
此处，MCE是用于该MBSFN区域内多个小区之间的无线资源协调与分配的实体。
MCE可以根据该MBSFN区域的MBMS业务量大小确定该MBSFN区域的用于传输MBMS数据的扩展的MBSFN资源。例如，假设某个FDD系统，根据某个MBSFN区域的MBMS业务量大小，确定需要大于六个子帧的无线资源用来传输MBMS数据，例如需要八个子帧用于传输MBMS数据，则MCE可以在MBSFN子帧集合之外的子帧中任意选择两个子帧， 例如确定子帧0和子帧5为该MBSFN区域的扩展的MBSFN资源。进一步的，该扩展的MBSFN资源可以剔除子帧中固定的资源开销，该固定的资源开销包括主同步信号(primary synchronization signal，简称PSS)、辅同步信号(secondary synchronization signal，简称SSS)以及物理广播信道(physical broadcast channel，简称PBCH)所固定占用的时频资源。
此外，MCE也可以根据该MBSFN区域内小区的寻呼参数，该MBSFN区域的MBMS业务量大小以及预设的准则确定该MBSFN区域的用于传输MBMS数据的扩展的MBSFN资源。此处的预设准则可以根据不同需求而不同，例如可以是最小冲突准则或者最大可用资源准则等，其中，最小冲突准则是指选择与该MBSFN区域的寻呼消息的冲突概率最小的子帧作为扩展的MBSFN资源，而最大可用资源准则是指剔除子帧中固定的资源开销以及寻呼消息所需要使用的资源，选择可用资源最大的子帧作为扩展的MBSFN资源。可以理解的是，本发明实施例对预设的准则不做限定。
按照最小冲突准则确定扩展的MBSFN资源的具体示例如下：假设某个FDD系统中的某个MBSFN区域一共有30个小区，根据该MBSFN区域内各个小区的寻呼参数确定出该MBSFN区域中一共有10个小区的寻呼时机PO为子帧9，10个小区的PO为子帧4和子帧9，10个小区的PO为子帧0、子帧4、子帧5和子帧9。如果根据该MBSFN区域的MBMS业务量大小确定需要大于六个子帧的无线资源用来传输MBMS数据，例如需要八个子帧用于传输MBMS业务，那么按照最小冲突准则，尽量减少与寻呼消息的冲突，MCE确定子帧0和子帧5为该MBSFN区域的扩展的MBSFN资源；如果根据该MBSFN区域的MBMS业务量大小确定需要七个子帧用于传输MBMS业务，那么MCE确定子帧5为该MBSFN区域的扩展的MBSFN资源；如果根据该MBSFN区域的MBMS业务量大小确定需要九个子帧用于传输MBMS业务，那么MCE确定子帧0、子帧5和子帧4为该MBSFN区域的扩展的MBSFN资源。
进一步地，MCE获取小区的寻呼参数的方法可以参考100a。
通过101，MCE确定了用于传输MBMS数据的扩展的MBSFN资源，以便增加MBMS容量。
可选地，在MCE确定扩展的MBSFN资源之前，MCE获取小区的能力信息，该能力信息中包括是否支持跨子帧调度寻呼传输块的能力指示。跨子帧调度寻呼传输块的详细介绍可以参考105。对于该MBSFN区域内的所有小区都支持跨子帧调度寻呼传输块的情况，MCE可以按照最小冲突准则确定扩展的MBSFN资源。
102，MCE向基站发送第一消息，该第一消息包括第一指示，该第一指示用于指示扩展的MBSFN资源的时频位置，该第一消息还包括小区标识和MBSFN区域标识中的至少一个。该基站所管理的全部小区或部分小区属于该MBSFN区域。
第一消息可以是新增的消息，也可以是已有的消息，例如，MBMS调度信息(MBMS SCHEDULING INFORMATION)消息或MCE配置更新(MCE CONFIGURATION UPDATE)消息，本发明实施例对此不做限定。
该第一指示可以为第一信元，第二信元和第三信元中的一种，用于指示该扩展的MBSFN资源的时频位置。
该第一信元为专用信元，用于指示MBSFN子帧集合之外的用于传输MBMS数据的子帧。例如，该第一信元可以为4比特的比特流，指示MBSFN子帧集合之外的4个子帧中为扩展的MBSFN资源的子帧；或者，该第一信元可以为16比特的比特流，指示连续4个无线帧中MBSFN子帧集合之外的16个子帧中为扩展的MBSFN资源的子帧。
该第二信元为对现有的MBSFN子帧配置信元的扩展，用于指示MBSFN子帧集合中用于传输MBMS数据的子帧和MBSFN子帧集合之外的用于传输MBMS数据的子帧。例如，该第二信元可以是对3GPP中的36.443协议和/或36.331协议中的MBSFN子帧配置(MBSFN Subframe  Configuration)信元中的子帧分配(Subframe Allocation)信元的扩展；该第二信元可以是10比特的比特流，指示子帧0到9中用于传输MBMS数据的子帧；或者，该第二信元可以是40比特的比特流，指示连续的4个无线帧中用于传输MBMS数据的子帧。
该第三信元为专用信元，用于指示MBSFN子帧集合之外的用于传输MBMS数据的子帧以及该子帧中可以用于传输MBMS数据的时频资源。例如，该第三信元可以包括：用4比特指示MBSFN子帧集合之外的4个子帧中为扩展的MBSFN资源的子帧；用4比特指示MBMS数据与其它单播或广播数据共享的子帧；以及一个不定长的一维数组，数组长度等于MBMS数据与其它单播或广播数据共享的子帧个数，每个数组成员中指示该共享子帧中可以用于传输MBMS数据的视频资源。
可以理解的是，当101中确定的该扩展的MBSFN资源中的子帧都只用于MBMS数据的传输时，该第一指示可以为第一信元或第二信元；当101中确定的该扩展的MBSFN资源中至少有一个子帧用于MBMS数据和其它单播或广播数据共享资源时，该第一指示可以为第三信元。
基站收到来自MCE的第一消息后，如果第一消息包括小区标识，则该基站判断该小区标识所对应的小区是否是该基站管理的，如果是，则该基站通过该第一消息中的第一指示获取扩展的MBSFN资源的时频位置，该扩展的MBSFN资源用于后续的MBMS数据的传输。如果第一消息包括MBSFN区域标识，则该基站判断该基站内是否有属于该MBSFN区域的小区，如果有，则该基站通过该第一消息中的第一指示获取扩展的MBSFN资源的时频位置，该扩展的MBSFN资源用于后续的MBMS数据的传输。
可选地，当基站发现所述第一指示所指示的时频位置与某个小区的PO冲突，则基站触发该小区的SIB修改流程，更新该小区的寻呼参数配置，以减少该小区的PO与该扩展的MBSFN资源的冲突概率或完全避免该小区的PO与该扩展的MBSFN资源的冲突。该SIB修改的时间点不能晚于103 中基站向UE发送第二消息的时间点。
在本实施例中，基站1和基站2所管理的全部小区或部分小区属于该MBSFN区域。MCE向基站1和基站2分别发送第一消息。当还有其它基站所管理的全部小区或部分小区属于该MBSFN区域时，MCE还可以向其它基站发送第一消息。
通过102，可以使得基站获得MCE确定的用于传输MBMS数据的扩展的MBSFN资源的时频位置，以便基站能够在该扩展的MBSFN资源上传输MBMS数据，从而增加MBMS容量。
103，基站向UE发送第二消息，该第二消息包括第二指示，该第二指示用于指示该扩展的MBSFN资源的时频位置。该第二消息可以是新增的消息，也可以是已有的消息，例如，MBSFN区域配置(MBSFN AREA CONFIGURATION)消息，本发明实施例对此不做限定。
需要说明的是，该基站可以通过该基站内且属于该MBSFN区域的小区的空口向UE发送该第二消息。
该第二指示的具体实现方式可以参考102中第一指示的相关描述。该第二指示可以与该第一指示采用相同的实现方式，也可以采用不同的实现方式，本发明实施例对此不做限定。
在本实施例中，基站1和基站2分别向UE发送第二消息。当还有其它基站所管理的全部小区或部分小区属于该MBSFN区域的时候，其它基站也可以向UE发送第二消息。
在本发明实施例中，UE可称之为终端(Terminal)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal)等，该UE可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，UE可以是移动电话(或称为“蜂窝电话”)、具有移动终端的计算机等，例如，UE还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。
通过103，UE获得了扩展的MBSFN资源的时频位置，以便UE能够在该扩展的MBSFN资源上接收MBMS数据，从而增加MBMS容量。
104，UE在MBMS子帧集合和该扩展的MBSFN资源上接收MBMS数据，并对接收到的MBMS数据进行解调和译码。
基于101中所描述的确定扩展的MBSFN资源的方法，进一步的，为了实现寻呼消息与MBMS数据的动态资源共享，还可以包括如下步骤：
105，可选地，当有寻呼消息需要在该扩展的MBSFN资源上发送时，采用跨子帧调度的方式调度该寻呼消息的寻呼传输块。其中，跨子帧调度具体包括：该寻呼传输块对应的下行控制信息在第一寻呼时机PO上发送，该寻呼传输块在第二PO上发送，其中，第一PO可以根据该UE的寻呼参数和小区的寻呼参数确定，第一PO属于该扩展的MBSFN资源，第二PO不属于该扩展的MBSFN资源。
具体地，第二PO可以与第一PO属于同一个小区，也可以属于不同的小区。对于第二PO与第一PO属于同一个小区的情况，第二PO在第一PO之后的某个子帧；对于第二PO与第一PO属于不同的小区的情况，第二PO可以与第一PO在相同的时间位置，第二PO也可以在第一PO之后的某个子帧。
第二PO的位置可以通过隐式的方式通知UE，如第二PO的位置是预先设置的，也可以通过显示的方式通知UE，例如，可以通过无线资源控制消息或通过下行控制信息通知UE。其中，第二PO的位置包括第二PO所述的小区，以及第二PO所处的子帧位置。
如图2所示，PO包括子帧0、子帧4、子帧5和子帧9，在图中用
Figure PCTCN2016084996-appb-000001
标识。假设101中，MCE确定将子帧4作为该MBSFN区域的扩展的MBSFN资源。当子帧4要发送寻呼消息的时候，该寻呼消息所对应的下行控制信息仍然在子帧4上发送，但寻呼消息所对应的寻呼传输块在子帧4之后的第三个不属于该扩展的MBSFN资源的PO上传输，即在下一个无线帧的子 帧0上传输。
通过105，基站对扩展的MBSFN资源上出现的寻呼消息进行跨子帧调度，通过寻呼消息与MBMS数据的动态资源共享，从而增加MBMS数据所能使用的无线资源。
106，可选地，UE接收跨子帧调度的寻呼传输块。UE在第一PO上检测到该寻呼传输块对应的下行控制信息后，在第二PO上接收该寻呼传输块。
可选地，基于上述实施例，在MCE确定扩展的MBSFN资源之前，基站可以向MCE通知小区的寻呼参数，具体可以通过下述方式实现：
100a，基站向MCE发送第三消息，该第三消息包括小区的寻呼参数。
基站可以在与MCE建立连接时或在小区的寻呼参数发生变化后向MCE发送第三消息，该第三消息包括小区的寻呼参数。该寻呼参数包括系统信息块2中的nB或非连续接收周期中的至少一个。该第三消息可以是新增的消息，例如，寻呼配置信息(PAGING CONFIGURATION INFORMATION)消息或寻呼配置指示(PAGING CONFIGURATION INDICATION)消息，也可以是已有的消息，例如，基站配置更新(ENB CONFIGURATION UPDATE)消息或M2建立请求(M2 SETUP REQUEST)消息，本发明实施例对此不做限定。
可选地，在100a之前，MCE发送第四消息至基站(见100b)，该第四消息用于请求小区的寻呼配置信息，该第四消息中包括小区标识和MBSFN区域标识中的至少一个，基站根据第四消息中的小区标识或MBSFN区域标识，向MCE发送第三消息，该第三消息中包括该小区标识对应的小区的寻呼参数或属于该MBSFN区域的小区的寻呼参数。如果第四消息中携带的小区标识所对应的小区是该基站管理的或者该基站所管理的小区中有属于该MBSFN区域的，那么该基站将反馈该小区的寻呼参数给MCE。第四消息可以是新增的消息，例如，寻呼配置请求(PAGING CONFIGURATION  REQUEST)消息，也可以是已有的消息，例如，MCE配置更新(MCE CONFIGURATION UPDATE)消息，本发明实施例对此不做限定。与第四消息相对应，第三消息可以是新增的消息，例如，寻呼配置响应(PAGING CONFIGURATION RESPONSE)消息，也可以是已有的消息，例如，MCE配置更新确认(MCE CONFIGURATION UPDATE ACKNOWLEDGE)消息，本发明实施例对此不做限定。
在本实施例中，基站1和基站2分别向MCE发送第三消息。当还有其它基站所管理的全部小区或部分小区属于该MBSFN区域的时候，其它基站也可以将各自管理的小区的寻呼参数通过第三消息发送给MCE。
通过100a，MCE可以获得该MBSFN区域内的小区的寻呼参数，以便给MCE确定扩展的MBSFN资源时参考。
在本实施例中，MCE向基站1和基站2分别发送第四消息。当还有其它基站所管理的全部小区或部分小区属于该MBSFN区域的时候，MCE还可以向该MBSFN区域内的其它基站发送第四消息。
通过100b，MCE可以向基站请求寻呼配置信息，以便基站向MCE反馈小区的寻呼参数。
通过上述方法，MCE确定了用于传输MBMS数据的扩展的MBSFN资源，并将该第一指示通过第一消息发送给基站，以便基站能够获得该扩展的MBSFN资源的时频位置，使得基站能够使用该扩展的MBSFN资源传输MBMS数据。基站收到来自MCE的第一指示后，将第二指示通过第二消息发送给UE，使UE获得扩展的MBSFN资源的时频位置，以便UE能够在该扩展的MBSFN资源上接收MBMS数据。通过上述方法，有效地增加了MBSFN资源，从而增加MBMS容量。
如上所述，MCE可以根据该MBSFN区域内小区的寻呼参数，该MBSFN区域的MBMS业务量大小以及预设的准则确定该MBSFN区域的用于传输MBMS数据的扩展的MBSFN资源。当预设的准则为最大可用资 源准则时，确定扩展的MBSFN资源的方法可以通过如下方式实现：
第一步，MCE根据MBSFN区域的各个小区的寻呼参数确定小区的能够用于传输MBMS数据的扩展的MBSFN资源，在确定扩展的MBSFN资源的过程中MCE还需要考虑小区的固定的资源开销，包括PSS、SSS以及PBCH所固定占用的时频资源；第二步，根据该MBSFN区域的各个小区各自的能够用于传输MBMS数据的扩展的MBSFN资源和该MBSFN区域的MBMS业务量大小，基于最大可用资源准则确定该MBSFN区域用于传输MBMS数据的扩展的MBSFN资源。
MCE根据小区的寻呼参数确定该小区的能够用于传输MBMS数据的扩展的MBSFN资源的方法可以参见图3。
MCE根据如图3所示的方法确定该MBSFN区域内各个小区各自的能够用于传输MBMS数据的扩展的MBSFN资源，进一步可以确定该MBSFN区域内各个小区的共同的能够用于传输MBMS数据的扩展的MBSFN资源，基于最大可用资源准则，结合该MBSFN区域的MBMS业务量大小，MCE可以最终确定该MBSFN区域用于传输MBMS数据的扩展的MBSFN资源。假设在一个LTE FDD系统中，某个MBSFN区域内有四个小区：小区0、小区1、小区2和小区3，它们各自的能够用于传输MBMS数据的扩展的MBSFN资源如表1所示，进一步确定该MBSFN区域内各个小区的共同的能够用于传输MBMS数据的扩展的MBSFN资源如表2所示。如果该MBSFN区域的MBMS数据在一个无线帧中需要八个子帧传输，则MCE从表2中该MBSFN区域内各个小区公共的能够用于传输MBMS数据的扩展的MBSFN资源中按照最大可用资源准则选出两个子帧，例如，MCE最终确定扩展的MBSFN资源为子帧4和子帧5中除中间6个PRB之外的时频资源。可以理解的是，对于按照最大可用资源准则确定扩展的MBSFN资源的场景，MBMS数据可能需要与其它单播或广播数据共享某个子帧资源。

表2
Figure PCTCN2016084996-appb-000003
301，MCE根据小区的寻呼参数确定小区的PO。具体的，根据寻呼参数计算PO的方法，可以参考3GPP的36.304 V13.1.0(2016-03)协议中的第7章。假设LTE FDD系统的某个小区的寻呼参数nB＝2T，则该小区可能的PO为子帧4和子帧9。
302，对MBSFN子帧集合外的子帧逐一判断是否是301中计算出来的该小区的PO。对于FDD系统，MBSFN子帧集合外的子帧包括子帧0、子帧4、子帧5和子帧9，对于TDD系统，MBSFN子帧集合外的子帧包括子帧0、子帧1、子帧5和子帧6。
303，如果MBSFN子帧集合外的某个子帧不是该小区的PO，则该子帧中除了用于传输PSS、SSS和PBCH之外的可用于传输数据的PRB为该小区能够用于传输MBMS数据的扩展的MBSFN资源。
在本实施例中，MBSFN子帧集合外的子帧0和子帧5不是该小区的PO，所以子帧0和子帧5中除了用于传输PSS、SSS和PBCH之外的可用于传输数据的时频资源是能够用于传输MBMS数据的扩展的MBSFN资源，为了基站处理简单起见，可以把子帧0和子帧5中除了中间6个PRB之外的时频资源作为该小区的能够用于传输MBMS数据的扩展的MBSFN资源。可以理解的是，这里6个PRB只是举例说明，实际的PRB个数与系统设计以及参数配置相关。
304，如果MBSFN子帧集合外的某个子帧是该小区的PO，则该子帧中除了用于传输寻呼传输块以及PSS、SSS和PBCH之外的可用于传输数据的PRB为该小区能够用于传输MBMS数据的扩展的MBSFN资源。
为了实现方便，可以限制寻呼传输块所使用的频率位置，例如，限制寻呼传输块仅使用载波中心频点附近的PRB资源，如果传输该小区的寻呼传输块以及PSS、SSS和PBCH需要12个PRB，则该子帧除中间12个PRB之外的可用于传输数据的时频资源作为该小区的能够用于传输MBMS数据的扩展的MBSFN资源。可以理解的是，这里12个PRB只是举例说明，实际的PRB个数与系统设计以及参数配置相关。
通过图3所示的方法，可以确定小区的能够用于传输MBMS数据的扩展的MBSFN资源。
