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详细地描述。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、基站又可以称之为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B (Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、Wifi接入点(Access Point，AP)等。
2)、终端，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备、连接到无线调制解调器的其他处理设备等。
3)、交互，本申请中的交互是指交互双方彼此向对方传递信息的过程，这里传递的信息可以相同，也可以不同。例如，交互双方为基站1和基站2，可以是基站1向基站2请求信息，基站2向基站1提供基站1请求的信息。当然，也可以基站1和基站2彼此向对方请求信息，这里请求的信息可以相同，也可以不同。
4)、“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
随着通信技术的发展，通信系统已经演进为如图1所示的通信架构。如图1所示，该通信系统包括基站110和核心网(Core Network，CN)设备120，终端130通过基站110接入无线网络，且通过CN设备120实现终端130与外部网络的通信。该系统中，基站110之间可以进行信息交互，例如在长期演进(Long Term Evolution，LTE)系统中，基站之间的接口称为X2接口，且基站110之间可以通过X2接口进行信息交互。此外，基站110与终端130之间的接口称为Uu口，又称之为空口，基站110与终端130之间通过空口进行通信。基站110与CN设备120之间的接口称为S1接口，基站110与CN设备120通过S1接口进行通信，CN设备120可以包括移动性管理实体(Mobility Management Entity，MME)和服务网关(Serving Gateway，S-GW)，基站110与S-GW之间实现用户面信息交互，基站110与MME之间实现控制面信息 交互，本发明实施例在此不再详述。
在LTE系统中，基站之间状态信息的交互过程如图2至图4所示。当源基站需要获取目标小区的状态信息时，首先找到目标小区所在的基站，即目标基站；而后向目标基站发送请求消息(S210)，以向目标基站请求目标小区的状态信息；该请求消息包括源基站分配的源基站测量标识、目标小区的标识。目标基站接收到请求消息之后，会相应分配目标基站测量标识；并根据请求消息执行对目标小区的状态信息的测量，获得状态信息，并通过响应消息报告给源基站(S220)，且在报告过程中会携带目标基站测量标识，如图2所示；而后，目标基站可以周期性向源基站报告目标小区的状态信息(S230)，直到源基站通知目标基站停止对目标小区的状态信息的测量和报告，如图4所示。如果目标基站无法完成对目标小区的状态信息的测量，则通过失败消息通知源基站(S240)，即此时的响应消息为失败消息，如图3所示。以上基站测量标识是正整数，取值范围例如为1至4095，即[1,4095]。
源基站通知目标基站停止对目标小区的状态信息的测量和报告也可以通过图2所示的请求消息来完成的。此时，该请求消息相对于以上步骤210中的请求消息增加了目标基站测量标识，以通过该标识通知目标基站停止对其所分配的此目标基站测量标识所对应的所有小区的测量和报告。为了区分该请求消息是用于请求状态信息测量和报告，还是用于指示停止状态信息测量和报告，可以在请求消息中增加指示信元，该指示信元用于指示该请求消息是用于向目标请求目标小区的状态信息，还是用于通知目标基站停止对目标小区的状态信息的测量和报告。该指示信元可以设置两个取值，分别用于指示以上两种情况。
例如，以上请求消息为资源状态请求(resource status request)消息，且该资源状态请求消息中包括源基站分配的源基站测量标识(Measurement ID)、目标小区的小区标识(Cell ID)。此外，该资源状态请求消息还包括指示信元，该指示信元例如为注册请求(Registration Request)信元，当该注册请求信元的值设置为“开始”(“start”)时，目标基站将根据资源状态请求消息中的信 元对目标小区的状态信息进行测量和报告。当该注册请求信元的值设置为“停止”(“stop”)时，目标基站将停止所有小区的测量和报告，该所有小区是指本次状态信息交互所需要测量的所有小区。每次状态信息的交互是通过测量标识来标识的，即以上分配的源基站测量标识和目标基站测量标识用于标识本次状态信息交互过程，则停止测量和报告的小区即源基站测量标识和目标基站测量标识所标识的状态信息交互过程中的所有所需测量的小区。
此外，目标基站报告哪个或哪些状态信息(例如报告负载和/或信道质量)可以由源基站指示，此时该请求消息中还可以携带测量参数，用于指示需要目标基站测量和报告的状态信息。目标基站对状态信息的报告形式也可以由源基站指示，此时，该请求消息还可以携带报告周期等信元，用于指示目标基站报告目标小区的状态信息的周期。
需要说明的是，以上目标小区可以是一个，也可以是多个，也就是说源基站可以要求目标基站报告该目标基站的一个或多个小区的状态信息。相应的，请求消息中的小区标识可以是一个，也可以是多个。
可见，目前，源基站在第一次向目标基站请求状态信息时，会分配源基站测量标识，并将需要获知的状态信息的目标小区的小区标识和该源基站测量标识发送给目标基站。目标基站会基于该请求分配目标基站测量标识，并将该目标基站测量标识发送给源基站。如此，本次状态信息交互过程便通过该源基站测量标识和目标基站测量标识进行标识。当源基站需要获取目标基站的其它小区的状态信息时，需要发起一个新的状态信息交互过程，即分配新的源基站测量标识，并将该其它小区的小区标识和该新的源基站测量标识发送给目标基站，目标基站基于该新的源基站测量标识分配新的目标基站测量标识，发送给源基站。当源基站需要停止对目标小区的状态信息获取时，源基站需要向目标基站发送源基站测量标识和目标基站测量标识，以便目标基站基于这对测量标识停止对应的所有小区的状态信息的测量和报告。
可见，当源基站已经向目标基站发起一次状态信息交互过程时，如果源基站还需要获取目标基站的其它小区的状态信息时，需要发起新的状态信息 交互过程，此时，需要分配新的基站测量标识。此外，每次源基站需要停止对某个小区的状态信息获取时，需要同时停止该小区对应的状态交互过程中的所有小区的状态信息获取。
例如，源基站需要获取小区Cell 1至Cell M的状态信息，从而发起状态信息交互过程，并为本次状态信息交互过程分配源基站测量标识1；而后将源基站测量标识1和小区Cell 1至Cell M的小区标识发送给目标基站。目标基站接收到源基站发送的消息之后，为本次状态信息交互过程分配目标基站测量标识2，并将该目标基站测量标识2通过响应消息发送给源基站。当源基站还需获取目标基站的小区Cell M+1至Cell N的状态信息时，源基站会发起新的状态信息交互过程，并为该状态信息交互过程分配源基站测量标识3；而后将源基站测量标识3和小区Cell M+1至Cell N的小区标识通过请求消息发给目标基站，目标基站接收到源基站发送的消息之后，为该新的状态信息交互过程分配目标基站测量标识4，并将该目标基站测量标识4通过响应消息发送给源基站。当源基站需要停止对小区Cell 1的状态信息的获取时，源基站会将源基站测量标识1和目标基站测量标识2发送给目标基站，目标基站基于此停止相应状态信息交互过程中的所有小区，即小区Cell 1至Cell M的状态信息交互。以上M和N为正整数，且N大于M。
以上信息交互过程，无论源基站是否向目标基站发起过状态信息交互过程，每次源基站需要获取目标基站的小区(当前未有针对该小区的状态信息在交互)的状态信息时，都需要源基站和目标基站分配新的测量标识，如此随着信息交互需求的增加，对测量标识的数量要求不断增加，从而引起测量标识不足，无法进行信息交互的问题。
此外，针对每次信息交互过程中某个小区的状态信息交互过程的停止需求，会同时停止该信息交互过程所需要的所有小区的状态信息交互，如此，当对该信息交互过程中其它小区的状态信息的需求还存在时，会发起新的状态信息交互过程，导致信息交互效率低下。
考虑到以上问题，以下实施例在源基站已经向目标基站发起过状态信息 的交互过程时，源基站可以重复利用源基站和目标基站已经分配的测量标识，在再次需要获取目标基站的小区(当前未有针对该小区的状态信息在交互)的状态信息时，利用该源基站分配的源基站测量标识和目标基站分配的目标基站测量标识，向目标基站请求该小区的状态信息，且目标基站基于该目标基站测量标识，不会针对该请求再分配目标基站测量标识，如此，可以在现有测量标识的基础上实现增量启动某些小区的状态信息交互的功能，节省测量标识的开销。例如，在以上示例中，当源基站还需获取目标基站的小区Cell M+1至Cell N的状态信息时，源基站不会发起新的状态信息交互过程，而是利用之前分配的源基站测量标识1和目标基站测量标识2向目标基站请求小区Cell M+1至Cell N的状态信息。
此外，在源基站需要停止对某个小区的测量信息的获取时，源基站可以向目标基站发送该小区的小区标识以及源基站测量标识1和目标基站测量标识2，目标基站基于该小区标识只停止该小区的状态信息测量和报告，而继续对源基站测量标识1和目标基站测量标识2所标识的这次状态信息交互过程中的其它小区的状态信息的测量和报告。如此，可以实现停止部分小区的状态信息测量和报告功能，提高了信息交互效率。
应理解，以上实施例虽然以LTE系统为例，但是其可以用于其它通信系统中，且该通信系统支持基站之间的信息交互。。
请参考图5，其为本发明实施例提供的一种状态信息请求方法的信令流图。如图5所示，该方法包括如下步骤：
S510：第一基站向第二基站发送第一请求消息，用于请求第二基站的第一小区的状态信息，该第一请求消息包括第一测量标识和第一小区的小区标识。
S520：第二基站接收第一基站发送的第一请求消息，根据该第一请求消息分配第二测量标识。
S530：第二基站向第一基站发送对第一请求消息的响应消息，该响应消息包括第二测量标识。
此时，第二基站还可以将第一小区的状态信息也通过响应消息发送给第一基站。该状态信息可以是第二基站中已经存储的第一小区的状态信息，也可以是第二基站应第一请求消息测量获得的一段时间内的状态信息，并在获得该状态信息后将第二测量标识和状态信息一同发送给第一基站。
S540：第二基站根据第一请求消息对第一小区进行状态信息的测量。
第一基站接收以上步骤S530中的响应消息，获得第二测量标识，如此，当第一基站需要获取第二基站内其它小区的状态信息时，可以无需分配新的测量标识，而是利用之前分配的第一测量标识和获取的第二测量标识启动对其它小区的状态信息交互过程。即包括如下步骤：
S550：第一基站向第二基站发送第二请求消息，用于请求第二基站的第二小区的状态信息，该第二请求消息包括第一测量标识、第二测量标识、和第二小区的小区标识。
S560：第二基站接收第二请求消息，根据第二请求消息对第二小区进行状态信息的测量。
需要说明的是，以上步骤S530和S540之间没有顺序要求，可以同时进行，也可以先执行步骤S530，再执行步骤S540；也可以先执行步骤S540，在执行步骤S530。此外，步骤S540的状态信息的测量会一直执行，报告也会定期进行，直到第一基站通知第二基站停止。
此时，以上方法还包括如下步骤：
S570：第二基站向第一基站发送第一小区和第二小区的状态信息，其中，第一小区的状态信息和第二小区的状态信息可以同时发送，也可以分别发送。
在一种实现方式中，第一基站在第一请求消息中携带第一小区的状态信息报告周期，以便第二基站根据该报告周期定期向第一基站发送第一小区的状态信息。当第一基站需要请求第二基站的第二小区的状态信息时，第一基站可以不需要在第二请求消息中携带报告周期，且第二基站根据第一请求消息中的报告周期，向第一基站发送第二小区的状态信息。如此，当第二基站收到第二请求消息之前，可以发送第一小区的状态信息；当第二基站收到第 二请求消息之后，可以同时发送第一小区和第二小区的状态信息，如此可以节省第一基站和第二基站之间交互的信元数量，节约了资源。
在另一种实现方式中，第一请求消息和第二请求消息中分别携带第一报告周期和第二报告周期，如此，第二基站分别按照第一报告周期和第二报告周期分别上报第一小区的状态信息和第二小区的状态信息。
在又一种实现方式中，第一请求消息和第二请求消息中均不携带报告周期，第二基站预先设置好第一小区的状态信息和第二小区的状态信息的报告周期，当第二基站收到第一请求消息和第二请求消息之后，便根据该预先设置好的报告周期发送第一小区的状态信息和第二小区的状态信息。其中，第一小区的报告周期和第二小区的报告周期可以相同，也可以不同。
在以上方法中，第二基站可以支持第一基站请求的小区的状态信息的测量和报告，当第二基站无法支持第一基站所请求的小区的状态信息的测量和报告时，第二基站向第一基站发送的响应消息为失败消息。此时，第二基站可以对本次失败的信息交互过程分配第二测量标识，以便后续第一基站再发起与第二基站的信息交互过程时，可以直接利用该第二测量标识。此时，与以上实施例的区别在于，步骤S530中的响应消息为失败消息，且步骤S570中的状态信息只包括第二小区的状态信息。
当然，第二基站也可以不分配第二测量标识，而只在可以支持第一基站所需要的小区的状态信息的测量和报告时才分配第二测量标识。此时，第一基站在发送第二请求消息时，便不会携带第二测量标识，而由第二基站接收到该第二请求消息时，再为该信息交互过程分配第二测量标识。
请参考图6，其为本发明实施例提供的一种状态信息停止方法的信令流图。如图6所示，该方法包括如下步骤：
S610：第一基站向第二基站发送第一请求消息，用于请求第二基站的多个第一小区的状态信息，该第一请求消息包括第一测量标识和第一小区的小区标识。
S620：第二基站接收第一基站发送的第一请求消息，根据该第一请求消 息分配第二测量标识。
S630：第二基站向第一基站发送对第一请求消息的响应消息，该响应消息包括第二测量标识。
S640-S650：第二基站根据第一请求消息对多个第一小区进行状态信息的测量和报告。
S660：第一基站向第二基站发送第三请求消息，该第三请求消息包括第一测量标识、第二测量标识、和停止小区的小区标识，该停止小区为多个第一小区的子集，即停止小区为多个第一小区中一部分(包括一个)。该第三请求消息用于请求第二基站停止对停止小区的状态信息的测量和报告。
S670：第二基站根据第三请求消息停止对多个第一小区中的部分小区的状态信息的测量和报告，即停止对停止小区的测量和报告。
可见，在本实施例中，可以利用第二测量标识停止对第一测量标识和第二测量标识所标识的状态信息交互过程中部分小区的状态信息的测量和报告。相对于现有技术全部停止的情况，可以在第一基站还需要获取该状态信息交互过程中某个或某些小区的状态信息时，无需重新发起状态信息交互过程，提高了状态信息交互的效率。
以上方法还可以利用在停止多个第二小区的部分小区的状态信息的测量和报告过程；此外，也可以利用在停止第一小区(包括一个或多个)和第二小区(包括一个或多个)所构成的小区集合中任一个子集的状态信息的测量和报告过程。也就是说，以第一测量标识和第二测量标识所标识的状态信息交互过程中任一个或一些小区的状态信息的测量和报告过程均可以利用以上方法来实现。
为了节约消息类型，以上第一请求消息，第二请求消息和第三请求消息可以采用相同的消息类型，且在该消息中增加指示信元，该指示信元用于指示对应的请求消息是用于请求状态信息，还是用于请求停止状态信息的测量和报告。
例如，请参考以下表格1，其为一种请求消息的信元示例表。以上第一、 第二和第三请求消息例如均为资源状态请求消息，其具有如表1所示的信元：第一测量标识、第二测量标识、注册请求信元、小区标识和报告周期等。其中，在LTE系统中，第一测量标识例如为eNB1测量标识(eNB1Measurement ID)，第二测量标识例如为eNB2测量标识(eNB2Measurement ID)。
表1
Figure PCTCN2015096226-appb-000001
Figure PCTCN2015096226-appb-000002
需要说明的是，这里仅为举例，该请求消息还可以包括其它信元，由于与本发明实质无关，在此不再列出。
当该请求消息携带第一测量标识而不携带第二测量标识时，表示该请求消息用于第一基站初次向第二基站请求状态信息，其中小区标识表明了请求哪个或哪些小区的状态信息。当该请求消息携带第一测量标识和第二测量标识时，表示该请求消息用于第一基站再次向第二基站请求状态信息或指示第二基站停止状态信息的测量和报告，其中注册请求信元的取值为“开始”时，表明该请求消息用于第一基站再次向第二基站请求状态信息，小区标识表明了再次请求哪个或哪些小区的状态信息；其中注册请求信元的取值为“停止”时，表明该请求消息用于第一基站指示第二基站停止状态信息的测量和报告，小区标识表明了停止哪个或哪些小区的状态信息的测量和报告。
以下将结合实际应用场景对上述涉及的状态信息请求方法，进行详细说明。
本发明实施例中以LTE系统为例进行说明，第一基站为eNB1，第二基站为eNB2。假设eNB1首次请求eNB2覆盖下的小区A的状态信息，则所述eNB1向所述eNB2发送第一请求消息，所述第一请求消息中携带eNB1分配的eNB1Measurement ID和小区A的小区标识。eNB2接收eNB1发送的第一请求消息请求，解析所述第一请求消息，确定eNB1请求小区A的状态信息，则将小区A作为测量对象并执行对小区A的负载测量。
本发明实施例中，eNB2在成功完成小区A的负载测量后，向eNB1反馈针对小区A的资源状态信息响应(RESOURCE STATUS RESPONSE)，并在所述RESOURCE STATUS RESPONSE中携带所述eNB2Measurement ID。eNB2若未能完成小区A的负载测量，则向eNB1反馈资源状态信息失败(RESOURCE STATUS FAILURE)响应。
本发明实施例中，eNB1接收eNB2反馈的RESOURCE STATUS RESPONSE，并获取小区A的状态信息，eNB1与eNB2之间进行的小区A的状态信息交互，通过eNB1Measurement ID和eNB2Measurement ID进行标识。
假设eNB1需要再次请求eNB2覆盖下的小区B的状态信息，则所述eNB1判断是否获取到eNB2Measurement ID，即判断在本站是否已经请求过eNB2的小区的状态信息。若eNB1获取到eNB2Measurement ID，则eNB1向eNB2发送第二请求消息，所述第二请求消息中携带所述eNB2Measurement ID以及小区B的小区标识。若eNB1未获取到eNB2Measurement ID，则eNB1等待接收eNB2发送的状态信息响应(RESOURCE STATUS RESPONSE)或者状态信息失败响应(RESOURCE STATUS FAILURE)。若eNB1接收到eNB2发送的RESOURCE STATUS RESPONSE，则确定获取到eNB2分配的eNB2Measurement ID，并按照上述方式发送第二请求消息。若eNB1接收到eNB2发送的RESOURCE STATUS FAILURE，则确定未获取到eNB2分配的eNB2Measurement ID，可将小区B的状态信息请求作为首次请求，执行发送首次请求状态信息的过程，在向所述eNB2发送的请求消息中携带小区B的小区标识，不携带eNB2Measurement ID。
本发明实施例中，eNB1向eNB2发送的第二请求消息中还可携带eNB1Measurement ID，使得eNB2可通过eNB1Measurement ID和eNB2Measurement ID，确定已经进行过状态信息的交互。
本发明实施例中eNB2接收到eNB1发送的第二请求消息后，通过解析该第二请求消息，确定该第二请求消息中携带有eNB1Measurement ID和eNB2Measurement ID，则在本站查找eNB2Measurement ID对应的测量对象集合， 例如本发明中可查找到eNB2Measurement ID对应的测量对象为小区A。eNB2查找到测量对象集合后，将小区B，保存到待测量对象集合中，并执行小区B状态信息的测量。eNB2执行小区B的状态信息的测量后，根据测量结果，向eNB1反馈针对所述小区B的RESOURCE STATUS RESPONSE或者RESOURCE STATUS FAILURE。
本发明上述实施例中，可实现将不同请求消息对应的响应消息，通过不同的RESOURCE STATUS RESPONSE或者RESOURCE STATUS FAILURE发送。
可选的，本发明中eNB1向eNB2发送第二请求消息时无需携带周期信元，所述周期信元用于指示所述eNB2周期性报告状态更新消息(RESOURCE STATUS UPDATE)，所述周期信元，例如可以是报告周期信元(Reporting Periodicity)和参考信号接收功率((Reference Signal Receiving Power，RSRP)测量报告报告周期信元(Reporting Periodicity of RSRP Measurement Report)。
可选的，本发明实施例中eNB1向eNB2发送第二请求消息时，若携带周期信元，则eNB2接收到该第二请求消息后，丢弃所述第二请求消息中携带的周期信元。本发明实施例中丢弃第二请求消息中携带的周期信元，是指无论第二请求消息中是否携带周期信元，所述eNB2不做与所述第二请求消息中携带的周期信元相关的数据处理，并不按照所述第二请求消息中携带的周期信元指示的时间周期发送RESOURCE STATUS UPDATE，而是按照固定的周期，例如第一请求消息中携带的周期信元指示的周期，将所有成功完成状态信息测量的状态信息合并到一条RESOURCE STATUS UPDATE中，能够节省RESOURCE STATUS UPDATE的发送次数，进而节省X2接口的带宽。
需要说明的是，本发明上述涉及的具体实施例是以eNB1与eNB2已经进行了小区A的状态信息请求后，再进行小区B的状态信息请求为例进行说明的，故是在需要发送第二请求消息的情况下，进行是否收到eNB2Measurement ID的判断的，但在具体实施时并不限定。例如，结合本发明的思想，可以有另一种实施方案，即：不区分是首次发送请求消息还是再次发送请求消息， 都进行是否收到目标基站测量标识的判断。
针对源基站需要停止指定小区状态信息测量和报告的具体应用场景，例如可以是，eNB1确定需要停止小区A或者小区B的状态信息的测量和报告，则eNB1可向eNB2发送第三请求消息，第三请求消息中包括小区A或者小区B的小区标识，eNB2接收到eNB1发送的第三请求消息后，停止小区A或者小区B的状态信息的测量和报告。
需要说明的是，本发明实施例中当目标基站(eNB2)将所有小区的状态信息都停止测量和报告后，释放eNB2Measurement ID，以节省资源。
