本申请主张在2016年11月28日在中国提交的中国专利申请号No.201611066298.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种获取邻区发现信号测量时间配置DMTC信息的方法及装置。
背景技术
MulteFire(MF)是一种将长期演进(LTE，Long Term Evolution)扩展到非授权频段的无线接入技术。该技术可以不借助授权频段载波独立运行于非授权频谱中。为了与其他非授权频段设备(例如无线保真设备)公平占用非授权频段信道及避免非授权频段设备之间相互干扰，MF物理层引入类似无线保真(WiFi，Wireless Fidelity)的载波监听技术的先听后说(LBT，Listen Before Talk)机制。在基站或终端监听到非授权频段信道被占用时，即LBT失败时，停止发送信号；当监听到信道空闲时，即LBT成功时，发送信号。
为了提高LBT机制下基站的下行公共控制信号传输效率，MulteFire引入了发现参考信号(DRS，Discovery Reference Signal)。DRS包含了主要的下行公共控制信号，包括系统广播、主同步信号(PSS，Primary Sync Signal)、辅同步信号(SSS，Secondary Sync Signal)、增强主同步信号(ePSS，enhanced Primary Sync Signal)、增强辅同步信号(eSSS，enhanced Secondary Sync Signal)、小区参考信号(CRS，Cell Reference Signal)、主系统信息块(MIB，Master Information Block)和增强的系统信息块(SIB-MF，System Information Block Multefire)，DRS占用一个下行子帧中的12个或14个符号(Symbol)。终端(UE)可以在发现信号测量时间配置(DMTC，Discovery Signals Measurement Timing Configuration)窗口内接收DRS以进行下行同步、接收MIB和SIB-MF。MF小区只在DRS子帧或者其他有物理下行共享信道 (PDSCH，Physical Downlink Shared Channel)发送的子帧发送CRS，因此UE可以仅在DMTC窗口内对MF服务小区或MF邻小区进行信道测量，用于小区选择、小区重选或切换。若基站不知道MF邻小区的DMTC参数，基站无法向UE指示MF邻小区的DMTC窗口位置，UE可能在任意时间对MF邻小区进行DRS信号质量测量。在相关LTE技术中，基站可通过与邻基站之间的X2接口建立过程获得相邻基站小区的信息，但如果基站与邻小区所属基站之间没有X2接口，则无法获取该邻小区的DMTC信息。因此，基站所服务的UE不能在邻小区DMTC窗口内进行DRS信号质量测量，导致增大UE的功耗。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。应当理解，虽然附图中显示了本公开的示例性实施例，但是本公开可以以各种形式实现而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
在Multefire(MF)系统中，基站可以向终端(UE)分别发送本小区、同频邻小区以及异频邻小区的发现信号测量时间配置(DMTC，Discovery Signals Measurement Timing Configuration)信息，通过增强的系统信息块(SIB-MF，System Information Block Multefire)广播当前MF服务小区的DMTC信息，通过SIB3广播或通过UE专用无线资源控制(RRC，Radio Resource Control)消息发送同频邻小区的DMTC信息，通过SIB5广播或通过UE专用测量配置RRC消息发送指定频点的异频邻小区的DMTC信息，使UE根据DMTC信息获知所本小区(所驻留或已连接小区)的DRS发送时间窗口、同频邻小区和异频邻小区的DRS发送时间窗口以进行信道测量。本小区DMTC信息包括DMTC参数。DMTC参数包括：DMTC窗口持续时间(dmtc-WindowSize)、DMTC窗口的周期(dmtc-Periodicity)和子帧偏移(dmtc-Offset)，其中dmtc-periodicity为40ms、80ms或160ms，dmtc-Offset为0到159。
UE可根据本小区的DMTC信息使用以下公式确定本小区的DMTC窗口位置，从而在DMTC窗口内对本小区进行信道测量。
DMTC起始帧号mod T＝FLOOR(dmtc-Offset/10)；
DMTC起始子帧号＝dmtc-Offset mod 10；
T＝dmtc-Periodicity/10。
邻小区的DMTC信息包括同步标识，当同步标识为异步时，指示本小区 的邻小区中包含与本小区异步的小区。邻小区的DMTC信息中还可包括以下至少一个：与本小区同步的邻小区的DMTC参数和与本小区异步的邻小区的DMTC参数。
针对相关技术中终端不能在邻小区DMTC窗口内进行DRS信号质量测量，导致UE可能在任意时间对MF邻小区进行发现参考信号(DRS，Discovery Reference Signal)信号质量测量，增大UE的功耗的问题，本公开的实施例提供了一种获取邻区发现信号测量时间配置DMTC信息的方法及装置。在本公开的方法和装置中，接收第二基站通过第二基站的邻区信息发送的第一小区(该第一小区为第二基站的服务小区的邻小区)的DMTC信息，并根据接收到的第一小区的DMTC信息向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个，使终端能在邻小区DMTC窗口内进行DRS信号质量测量，从而降低终端的功耗。
图1为本发明实施例的获取邻区发现信号测量时间配置DMTC信息的方法的流程图。该方法应用于第一基站，并且包括步骤101-102。
步骤101：获取第二基站通过第二基站的邻区信息发送的第一小区的DMTC信息。其中，第一小区为第二基站的服务小区的邻小区，第二基站可以是第一基站的邻基站，也可以不是第一基站的邻基站，且第一基站与第二基站均可以是MF基站、LTE基站、宽带码分多址(WCDMA)基站、时分同步码分多址(TD-SCDMA)基站或者全球移动通信系统(GSM)基站。
在本公开的实施例中，可根据X2接口消息或者S1接口消息，获取(即接收)第二基站发送的第一小区的DMTC信息。其中，第一小区的DMTC信息记录于X2接口消息或者S1接口消息中的第二基站的邻区信息中。需要说明的是，为便于第一基站识别第一小区，上述X2接口消息与S1接口消息均应包括第一小区的网络标识(NHN-ID)与小区全局标识符(ECGI)。
步骤102：将获取到的第一小区的DMTC信息保存在第二基站的邻区信息中。
其中，获取到的第一小区的DMTC信息包括第一DMTC信息和第二DMTC信息中的至少一个，第一DMTC信息包括第一小区的本小区DMTC信息，第二DMTC信息包括第一小区的同频邻小区DMTC信息和异频邻小 区DMTC信息中的至少一个。
具体的，第一小区的本小区DMTC信息包括第一小区的本小区的DMTC参数，第一小区的本小区的DMTC参数具体包括：DMTC窗口持续时间(dmtc-WindowSize)、DMTC窗口的周期(dmtc-Periodicity)和子帧偏移(dmtc-Offset)。第二DMTC信息包括以下至少一个：第一小区在系统信息SIB3中广播的同频邻小区DMTC信息，和在系统广播SIB5中广播的一个或多个异频邻小区DMTC信息。其中，同频邻小区或异频邻小区DMTC信息包括同步标识，当同步标识为异步时，指示第一小区的同频邻小区中包含与第一小区异步的小区，或者指示第一小区的异频邻小区中包含于第一小区异步的小区。第一小区的同频邻小区或异频邻小区DMTC信息中还包括以下至少一个：与第一小区同步的邻小区的DMTC参数和与第一小区异步的邻小区的DMTC参数。同步邻小区的DMTC参数或异步邻小区的DMTC参数包括DMTC窗口持续时间(dmtc-WindowSize)、DMTC窗口的周期(dmtc-Periodicity)和子帧偏移(dmtc-Offset)中的一项或多项。
可以看出，在第一基站与第一小区所属基站之间没有直接通信接口的情况下，第一基站依然可以从第二基站发送的邻区信息中获取第一小区的DMTC信息，使得第一基站能根据保存的第一小区的DMTC信息向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个，进而达到使终端能在邻小区DMTC窗口内进行DRS信号质量测量，降低终端的功耗的效果。
进一步的，图1所示的实施例中，上述步骤102的一种具体实现方式包括如下步骤1021至1022。
步骤1021：检测获取到的第一小区的DMTC信息是否包含子帧偏移。
步骤1022：若检测获取到的第一小区的DMTC信息包含子帧偏移，则将获取到的第一小区的DMTC信息的子帧偏移转换为DMTC窗口在第一基站的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第一小区的DMTC信息，并将经过子帧偏移转换处理后的第一小区的DMTC信息保存在第二基站的邻区信息中。
在具体实现中，第一基站可通过监听第一小区的下行同步信号获取第一 小区的子帧定时，从而将接收到的第一小区的DMTC信息的子帧偏移转换为在第一基站子帧定时下的子帧偏移，其中，第一小区与第一基站同步或异步。
上述步骤102的另一种具体实现方式包括如下步骤1023至1024。
步骤1023：确定第一小区是否与第一基站异步。
步骤1024：若第一小区与第一基站异步，则将不包含子帧偏移(即除了子帧偏移之外)的第一小区的DMTC信息保存在第二基站的邻区信息中，其中第一基站确定第一小区是否异步的方法包括：若接收到的第一小区的DMTC信息不包含子帧偏移，则确定第一小区与第一基站异步；或者，第一基站根据操作管理维护(OAM)配置的关于第一小区的同步信息确定第一小区与第一基站异步；或者，第一基站通过向第一小区所属基站询问同步信息以确定第一小区与第一基站异步。例如，第一基站可以通过S1接口的基站配置转发(eNB Configuration Transfer)消息询问第一小区所属基站的同步信息，其中，第一基站将eNB Configuration Transfer的SON Information Request字段设为时间同步信息(Time synchronisation Info)枚举值；第一小区所属基站收到后向第一基站发送包含同步信息的S1消息eNB Configuration Transfer以指示是否与第一基站异步。
进一步的，若第一基站确定第一小区与第一基站同步，则第一基站可将接收到的第一小区的DMTC信息的子帧偏移转换为DMTC窗口在第一基站的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第一小区的DMTC信息，并将经过子帧偏移转换处理后的第一小区的DMTC信息保存在第二基站的邻区信息中。
需要说明的是，当接收到的第一小区的DMTC信息包含子帧偏移时，是否对接收到的第一小区的DMTC信息的子帧偏移进行转换，主要取决于接收到的第一小区的DMTC信息的子帧偏移是否已经过转换。具体的，若第二基站在发送第一小区的DMTC信息时已对子帧偏移进行转换，那么第一基站在接收到第一小区的DMTC信息时便不需要再对子帧偏移进行转换，直接将接收到的第一小区的DMTC信息保存在第二基站的邻区信息中即可；而若第二基站在发送第一小区的DMTC信息时未对子帧偏移进行转换，那么第一基站在接收到第一小区的DMTC信息时便需要对子帧偏移进行转换，并在转换之 后，将经过子帧偏移转换处理后的第一小区的DMTC信息保存在第二基站的邻区信息中。
在此，以具体示例进一步阐述上述第一基站对接收到的第一小区的DMTC信息的子帧偏移进行转换的过程。例如，第一基站收到的第二基站发送的第一小区的DMTC信息的子帧偏移为9，第一基站计算第一小区DMTC窗口在第一基站子帧定时下的子帧偏移为1，那么此时第一基站会将第一小区的DMTC信息的子帧偏移设为1后进行保存。
其中，在图1所示的本公开的实施例中，在执行完上述步骤102之后，上述方法还包括步骤103。
步骤103：向终端发送第一基站服务小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。其中，向终端发送第一基站服务小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个的步骤103包括：根据保存的第一小区的DMTC信息，通过系统广播或专用测量配置无线资源控制RRC小区向终端发送第一基站服务小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。当然可以理解的是，第一基站在向终端发送第一基站服务小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个时，第一基站可以基于自身保存的一个或多个第一小区的DMTC信息，向终端发送第一基站服务小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。从而使终端能在邻小区DMTC窗口内进行DRS信号质量测量，达到降低终端功耗的效果。
在图1所示的本公开的实施例中，上述X2接口消息可以包括X2建立请求消息、X2建立响应消息、基站配置更新消息、基站配置更新响应消息或者DMTC响应消息。需要说明的是，不管是上述哪一种X2接口消息，上述第一小区的DMTC信息均记录于X2接口消息中的邻区信息(Neighbour Information)字段中新增的服务小区(Serving Cell)DMTC信息字段中。可见，该Serving Cell DMTC信息字段用于第二基站传输第一DMTC信息，即第一小区的本小区DMTC信息。
当第一小区的DMTC信息包括第一DMTC信息时，即Neighbour Information包括Serving Cell DMTC字段时。Serving Cell DMTC信息字段的 编码格式可以如表1所示，

在图1所示的本公开的实施例中，若第一基站通过X2接口消息接收第二基站发送的第一小区的DMTC信息，那么根据X2接口消息的不同，第一基站与第二基站之间的交互过程可存在以下几种方式。
如图2所示，第一种交互方式为：第一基站向第二基站发送X2建立请求(X2 Setup Request)消息后，接收第二基站发送的包含第一小区的DMTC信息的X2建立响应(X2 Setup Response)消息；或者，在第一基站与第二基站建立X2接口过程中，第一基站接收第二基站发送的包含第一小区的DMTC信息的X2 Setup Response消息。
第二种交互方式为：在第一基站与第二基站之间建立X2接口之后，第一基站接收第二基站发送的包含第一小区的DMTC信息的基站配置更新(ENB CONFIGURATION UPDATE)消息或基站配置更新响应(ENB configuration update acknowledge)消息。
如图3所示，第三种交互方式为：新增专用的DMTC请求消息和DMTC响应消息，第一基站通过X2接口向第二基站发送DMTC请求消息，然后接收第二基站发送的包含第一小区的DMTC信息的DMTC响应消息。
在图1所示的本公开的实施例中，上述S1接口消息可以为基站配置转发消息、核心网控制节点配置转发消息或者DMTC响应消息。
当S1接口消息为基站配置转发(eNB CONFIGURATION TRANSFER)消息时，如图4所示，第一基站与第二基站之间的交互方式为：第一基站向核心网控制节点(例如移动管理实体(MME))发送eNB CONFIGURATION TRANSFER消息以请求第二基站发送的第一小区的DMTC信息，然后通过核心网控制节点配置转发(CONFIGURATION TRANSFER)消息接收由核心 网控制节点转发的第二基站发送的第一小区的DMTC信息。其中，第一小区的DMTC信息包含在自优化网络信息(Son Information)字段的自优化网络信息响应(Son Information Response)字段中。
当然，第一基站还可通过核心网控制节点配置转发消息直接接收由核心网控制节点转发的第二基站发送的第一小区的DMTC信息。其中，第一小区的DMTC信息包含在Son Information字段的自优化网络信息请求(Son Information Request)字段中。
在图1所示的本公开的实施例中，在核心网控制节点CONFIGURATION TRANSFER或ENB CONFIGURATION TRANSFER消息的自优化网络配置转发(Son Configuration Transfer)字段增加DMTC信息字段，用于第二基站发送第一小区的DMTC信息。或者，在核心网控制节点CONFIGURATION TRANSFER或ENB CONFIGURATION TRANSFER消息的自优化网络配置转发(Son Configure Transfer)字段中Son Information字段的Son Information Request字段中增加DMTC信息的请求类型(枚举值)，该DMTC信息的请求类型(枚举值)用于第一基站请求第二基站发送第一小区的DMTC信息，并在核心网控制节点CONFIGURATION TRANSFER或ENB CONFIGURATION TRANSFER消息的Son Configure Transfer字段中Son Information字段的自优化网络信息回应(Son Information Reply)字段增加DMTC信息字段，该DMTC信息字段用于第二基站发送第一小区的DMTC信息。
其中，DMTC信息字段的Serving Cell information里的Neighbour Information包含Serving Cell DMTC字段用来传输第一DMTC信息，即第一小区的本小区DMTC信息。

在图1所示的实施例中，当S1接口消息包括DMTC响应消息时，如图5所示，第一基站与第二基站之间的交互方式为：新增专用的DMTC请求消息和DMTC响应消息，第一基站通过S1接口向核心网控制节点(MME或服务GPRS支持节点(SGSN))发送DMTC请求消息，由核心网控制节点将DMTC请求消息转发给第二基站，然后接收由核心网控制节点转发的第二基站发送的DMTC响应消息，其中包含第一小区的DMTC信息。
当然上述DMTC请求消息可能经过第二基站的核心网控制节点的转发，即第一基站的核心网控制节点先将DMTC请求消息发送到第二基站的核心网控制节点，再由第二基站的核心网控制节点将DMTC请求消息转发到第二基站。
由此可见，在图1所示的本公开的实施例中，通过第一基站获取第二基站通过第二基站的邻区信息发送的第一小区(该第一小区为第二基站的服务小区的邻小区)的DMTC信息，并将获取到的第一小区的DMTC信息保存在第二基站的邻区信息中，使得第一基站能根据保存的第一小区的DMTC信息向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个，进而达到使终端能在邻小区DMTC窗口内进行DRS信号质量测量，降低终端的功耗的效果。
图6A为本发明实施例的获取邻区发现信号测量时间配置DMTC信息的方法的流程图。图6A所示的获取邻区发现信号测量时间配置DMTC信息的方法应用于第一基站，并且该方法包括步骤601至602。
步骤601：获取第二基站通过第二基站的邻区信息发送的第一小区的DMTC信息，并将获取到的第一小区的DMTC信息保存在第二基站的邻区信息中，其中，第一小区为第二基站的服务小区的邻小区。
步骤602：接收第二基站通过第二基站的服务小区信息发送的第二小区的DMTC信息，并将接收到的第二小区的DMTC信息保存在第二基站的服务小区信息中，其中，第二小区为第二基站的服务小区。
其中，第二小区的DMTC信息包括第三DMTC信息，第三DMTC信息包括第二小区的本小区DMTC信息。当然第二小区的DMTC信息还可以包括第四DMTC信息，第四DMTC信息包括第二小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个，即，该第四DMTC信息包括第二小区的广播里涉及到的小区DMTC信息。
需要进一步说明的是，上述步骤601与步骤602之间不存在严格的先后顺序关系。且由于步骤601涉及到的第一小区的DMTC信息已在图1-图5所示的实施例中详细阐述，为避免过多重复在本实施例中不再进行过多赘述。
在图6A所示的实施例中，上述步骤602中接收第二小区的DMTC信息的具体包括：根据X2接口消息或者S1接口消息，接收第二基站发送的第二小区的DMTC信息。其中，第二小区的DMTC信息记录于X2接口消息或者S1接口消息的第二基站的服务小区信息中。需要说明的是，为便于第一基站识别第二小区，上述X2接口消息与S1接口消息均应包括第二小区的网络标 识(NHN-ID)与小区全局标识符(ECGI)。
在图6A所示的本公开的实施例的一种实现方式中，参见图6B，上述步骤602中的保存第二小区的DMTC信息具体包括步骤6021至6022。
步骤6021：检测接收到的第二小区的DMTC信息是否包含子帧偏移。
步骤6022：若检测接收到的第二小区的DMTC信息包含子帧偏移，则将接收到的第二小区的DMTC信息的子帧偏移转换为DMTC窗口在第一基站的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第二小区的DMTC信息，并将经过子帧偏移转换处理后的第二小区的DMTC信息保存在第二基站的服务小区信息中。
在具体实现中，第一基站可能通过监听第二小区的下行同步信号获取第二小区的子帧定时，将接收到的第二小区的DMTC信息的子帧偏移转换为在第一基站子帧定时下的子帧偏移。其中，第二小区与第一基站同步或异步。
在另一种实现方式中，参见图6C，上述步骤602中的保存第二小区的DMTC信息具体包括步骤6023至6025。
步骤6023：确定第二小区是否与第一基站异步。
步骤6024：若第二小区与第一基站异步，则将不包含子帧偏移(即除了子帧偏移之外)的第二小区的DMTC信息保存在第二基站的服务小区信息中。
第一基站确定第二小区是否异步的方法包括：若接收到的第二小区的DMTC信息不包含子帧偏移，则确定第二小区与第一基站异步；或者，第一基站根据操作管理维护(OAM)配置的关于第二小区的同步信息确定第二小区与第一基站异步；或者，第一基站通过向第二基站询问同步信息以确定第二小区与第一基站异步。例如，第一基站可以通过S1接口的基站配置转发(eNB Configuration Transfer)消息询问第二基站同步信息，其中，第一基站将eNB Configuration Transfer的SON Information Request字段设为时间同步信息(Time synchronisation Info)枚举值；第二基站收到后向第一基站发送包含同步信息的S1消息eNB Configuration Transfer以指示是否与第一基站异步。
步骤6025：若第一基站确定第二小区与第一基站同步，则第一基站可将接收到的第二小区的DMTC信息的子帧偏移转换为DMTC窗口在第一基站 的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第二小区的DMTC信息，并将经过子帧偏移转换处理后的第二小区的DMTC信息保存在第二基站的服务小区信息中。
需要说明的是，当接收到的第二小区的DMTC信息包含子帧偏移时，是否对接收到的第二小区的DMTC信息的子帧偏移进行转换，主要取决于接收到的第二小区的DMTC信息的子帧偏移是否已经过转换。具体的，若第二基站在发送第二小区的DMTC信息时已对子帧偏移进行转换，那么第一基站在接收到第二小区的DMTC信息时便不需要再对子帧偏移进行转换，直接将接收到的第二小区的DMTC信息保存在第二基站的服务小区信息中即可。若第二基站在发送第二小区的DMTC信息时未对子帧偏移进行转换，那么第一基站在接收到第二小区的DMTC信息时便需要对子帧偏移进行转换，并在转换之后，将经过子帧偏移转换处理后的第二小区的DMTC信息保存在第二基站的服务小区信息中。
在图6A所示的本公开的实施例中，在执行完上述步骤602之后，上述方法还包括步骤603。
步骤603：向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。步骤603的具体实现方式包括：根据保存的第一小区的DMTC信息和第二小区的DMTC信息中的至少一个，通过系统广播或专用测量配置无线资源控制RRC小区向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。
当然可以理解的是，当第一基站在向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个时，第一基站可以基于自身保存的一个或多个第一小区的DMTC信息和/或一个或多个第二小区的DMTC信息，向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。从而，终端能在邻小区DMTC窗口内进行DRS信号质量测量，达到降低终端功耗的效果。
在图6A-图6C所示的本公开的实施例中，上述X2接口消息可以包括X2建立请求消息、X2建立响应消息、基站配置更新消息、基站配置更新响应消息或者DMTC响应消息。需要说明的是，不管是上述哪一种X2接口消息， 上述第二小区的DMTC信息均记录于X2接口消息中的服务小区信息(Serving Cell Information)字段中新增的服务小区(Serving Cell)DMTC信息字段中。可见，该Serving Cell DMTC信息字段用于第二基站传输第三DMTC信息，即第二小区的本小区DMTC信息。当然，若第二小区的DMTC信息还包括第四DMTC信息，则还可在Serving Cell Information中新增Neigbour Cell DMTC字段，该Neigbour Cell DMTC字段用于传输第四DMTC信息。
在图6A-图6C所示的本公开的实施例中，上述S1接口消息可以包括基站配置转发消息、核心网控制节点配置转发消息或者DMTC响应消息。
参照图1至图5所示的实施例，阐述上述第二小区的DMTC信息的传输过程，若第一基站与第二基站之间不存在X2接口，则第一基站向核心网控制节点发送eNB CONFIGURATION TRANSFER消息以请求第二基站发送DMTC信息(即，第二小区的DMTC信息)，然后通过核心网控制节点CONFIGURATION TRANSFER消息接收由MME转发的第二基站发送的DMTC信息，DMTC信息包含在Son Information字段的Son Information Response字段中。或者，第一基站通过核心网控制节点CONFIGURATION TRANSFER消息直接接收由MME转发的第二基站发送的DMTC信息，DMTC信息包含在Son Information字段的Son Information Request字段中。
在核心网控制节点CONFIGURATION TRANSFER或ENB CONFIGURATION TRANSFER消息的Son Configure Transfer字段中Son Information字段的Son Information Request字段中增加DMTC信息的请求类型(枚举值)，用于第一基站请求第二基站发送DMTC信息，并在核心网控制节点CONFIGURATION TRANSFER或ENB CONFIGURATION TRANSFER消息的Son Configure Transfer字段中Son Information字段的Son Information Reply字段增加DMTC信息字段，用于第二基站发送DMTC信息。或者，在MME CONFIGURATION TRANSFER或ENB CONFIGURATION TRANSFER消息的Son Configuration Transfer字段增加DMTC信息字段，用于第一基站接收第二基站发送的DMTC信息。其中，DMTC信息字段的Serving Cell Information包含Serving Cell DMTC用来传输第三DMTC信息， 即第二小区的本小区DMTC信息，然后每个Serving Cell Information中的Neighbour Information包含Serving Cell DMTC字段用来传输第一DMTC信息，即第一小区的本小区DMTC信息，此外Serving Cell Information还可包含Intra-fCell DMTC、Inter-fCell DMTC，用来传输第四DMTC信息。其中，DMTC信息字段的格式可如表10所示。

图9为本发明实施例的获取邻区发现信号测量时间配置DMTC信息的方法的流程图。图9所示的获取邻区发现信号测量时间配置DMTC信息的方法 应用于第二基站。该方法包括步骤901-902。
步骤901：获取第一小区的DMTC信息。其中，第一小区为第二基站的服务小区的邻小区。
在图9所示的实施例中，上述步骤901的具体实现方式包括：通过X2接口或者S1接口，从第一小区所属基站处获取第一小区的DMTC信息；或者，从操作管理维护(OAM)配置信息中获取第一小区的DMTC信息。
步骤902：通过第二基站的邻区信息，将获取到的第一小区的DMTC信息发送给第一基站。
在图9所示的实施例中，上述步骤902的具体实现方式包括：将获取到的第一小区的DMTC信息记录于第二基站的邻区信息中；以及，根据X2接口消息或者S1接口消息，将记录有获取到的第一小区的DMTC信息的第二基站的邻区信息，发送给第一基站。上述X2接口消息可以包括X2建立请求消息、X2建立响应消息、基站配置更新消息、基站配置更新响应消息或者DMTC响应消息；S1接口消息可以包括基站配置转发消息、核心网控制节点配置转发消息或者DMTC响应消息。需要说明的是，为便于第一基站识别第一小区，上述X2接口消息与S1接口消息均应包括第一小区的网络标识(NHN-ID)与小区全局标识符(ECGI)。
在图9所示的实施例中，上述获取到的第一小区的DMTC信息包括第一DMTC信息和第二DMTC信息中的至少一个。其中，第一DMTC信息包括第一小区的本小区DMTC信息，第二DMTC信息包括第一小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个。
在具体实现中，第二基站可以采用如同图6A所示的实施例中第一基站从第二基站处获取第一小区DMTC信息或第二小区的DMTC信息的方法，从第三基站处获取第一小区的DMTC信息，即通过X2接口消息或S1接口消息接收第三基站通过第三基站的邻区信息或服务小区信息发送的第一小区的DMTC信息。其中，第一小区为第三基站的服务小区或邻小区。
在图9所示的实施例中，上述步骤902中将获取到的第一小区的DMTC信息发送给第一基站具体包括两种实现方式。第一种具体实现方式包括：将第一小区的DMTC信息中的子帧偏移转换为DMTC窗口在第一基站的子帧 定时下的子帧偏移，得到经过子帧偏移转换处理后的第一小区的DMTC信息；以及，将经过子帧偏移转换处理后的第一小区的DMTC信息发送给第一基站。在具体实现中，第二基站可以通过以下至少一个(i)监听第一小区的下行同步信号获取第一小区的子帧定时和(ii)通过监听第一基站服务小区的下行同步信号获取第一基站的子帧定时，从而将获取的第一小区的DMTC信息的子帧偏移转换为在第一基站子帧定时下的子帧偏移，其中，第一小区与第一基站同步或异步。
图10示出的示意图阐述了上述子帧偏移转换处理的过程。如图10所示，例如，第一小区DMTC窗口的子帧偏移为9，第二基站计算该第一小区DMTC窗口在第一基站子帧定时下的子帧偏移为1，第二基站将第一小区的DMTC信息中的子帧偏移设为1后发送给第一基站。
第二种具体实现方式包括：检测第一小区是否与第一基站异步；若第一小区与第一基站异步，则删除获取到的第一小区的DMTC信息中的子帧偏移，并将删除子帧偏移后的第一小区的DMTC信息发送给第一基站。
第二基站检测第一小区是否与第一基站异步的方法包括：第二基站根据操作管理维护(OAM)配置的关于第一小区的同步信息和关于第一基站的同步信息中的至少一个，确定第一小区与第一基站异步；或者，第二基站通过向第一小区所属基站询问同步信息以确定第一小区与第一基站异步。例如：第二基站可以通过S1接口的基站配置转发(eNB Configuration Transfer)消息询问第一小区所属基站同步信息，其中，第二基站将eNB Configuration Transfer的SON Information Request字段设为时间同步信息(Time synchronisation Info)枚举值；第一小区所属基站收到后向第二基站发送包含同步信息的S1消息eNB Configuration Transfer以指示第一小区是否与第二基站异步。若第一小区与第二基站同步，并且第二基站与第一基站同步，则第二基站可确定第一小区与第一基站同步；否则，第二基站确定第一小区与第一基站异步。进一步的，若第二基站确定第一小区与第一基站同步，则第二基站也可以将第一小区的DMTC信息中的子帧偏移转换为DMTC窗口在第一基站的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第一小区的DMTC信息；然后将经过子帧偏移转换处理后的第一小区的DMTC信息 发送给第一基站。
在图9所示的实施例中，上述方法还包括如下步骤903-904。
步骤903：获取第二小区的DMTC信息。其中，第二小区为第二基站的服务小区，第二小区的DMTC信息包括第三DMTC信息，第三DMTC信息包括第二小区的本小区DMTC信息。当然，上述获取到的第二小区的DMTC信息还可以包括第四DMTC信息，该第四DMTC信息包括第二小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个，即，该第四DMTC信息包括第二小区的本小区的广播里涉及到的小区DMTC信息。
步骤904：通过第二基站的服务小区信息，将获取到的第二小区的DMTC信息发送给第一基站。
在图9所示的实施例中，上述步骤904的具体实现方式可以包括：将获取到的第二小区的DMTC信息记录于第二基站的服务小区信息中；以及根据X2接口消息或者S1接口消息，将记录有获取到的第二小区的DMTC信息的第二基站的服务小区信息发送给第一基站。需要说明的是，为便于第一基站识别第二小区，上述X2接口消息与S1接口消息均应包括第二小区的网络标识(NHN-ID)与小区全局标识符(ECGI)。
在图9所示的实施例中，上述步骤904包括两种具体的实现方式。
第一种具体实现方式为：将第二小区的DMTC信息中的子帧偏移转换为DMTC窗口在第一基站的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第二小区的DMTC信息；以及将经过子帧偏移转换处理后的第二小区的DMTC信息发送给第一基站。其中，第二基站可以通过监听第一基站服务小区的下行同步信号获取第一基站的子帧定时，将第二小区的DMTC信息的子帧偏移转换为在第一基站子帧定时下的子帧偏移，其中，第二小区与第一基站同步或异步。
第二种具体实现方式为：检测第二小区是否与第一基站异步；若第二小区与第一基站异步，则删除获取到的第二小区的DMTC信息中的子帧偏移，并将删除子帧偏移后的第二小区的DMTC信息发送给第一基站。第二基站检测第二小区是否与第一基站异步的方法包括：第二基站根据操作管理维护(OAM)配置关于第一基站的同步信息确定第二小区与第一基站异步；或者 第二基站通过向第一基站询问同步信息以确定第二小区与第一基站异步。例如：第二基站可以通过S1接口的基站配置转发(eNB Configuration Transfer)消息询问第一基站同步信息，其中，第二基站将eNB Configuration Transfer 的SON Information Request字段设为时间同步信息(Time synchronisation Info)枚举值；第一基站收到后向第二基站发送包含同步信息的S1消息eNB Configuration Transfer以指示第一基站是否与第二基站异步。若指示第一基站与第二基站异步，则第二基站判断第一基站与第二小区异步。进一步的，若第二基站确定第二小区与第一基站同步，则第二基站也可以将第二小区的DMTC信息中的子帧偏移转换为DMTC窗口在第一基站的子帧定时下的子帧偏移，得到经过子帧偏移转换处理后的第一小区的DMTC信息；然后将经过子帧偏移转换处理后的第二小区的DMTC信息发送给第一基站。
由此可见，在图9所示的实施例中，通过获取第一小区(该第一小区为第一基站的服务小区的邻小区)的DMTC信息，并通过第二基站的邻区信息将第一小区的DMTC信息发送给第一基站，使得第一基站能根据接收到的第一小区的DMTC信息向终端发送第一基站小区的同频邻小区DMTC信息和异频邻小区DMTC信息中的至少一个，进而达到使终端能在邻小区DMTC窗口内进行DRS信号质量测量，降低终端的功耗的效果。
