Description

一种基站间接口建立的方法、第一基站及第二基站
本申请要求在2017年3月24日提交中国专利局、申请号为201710184459.5、发明名称为“一种基站间接口建立的方法、第一基站及第二基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种基站间接口建立的方法、第一基站及第二基站。
背景技术
随着科学技术在通信领域的不断发展，长期演进(Long Term Evolution，LTE)等无线接入技术已经得到了广泛的应用。
目前，在LTE系统中，相邻的基站(eNodeB，eNB)A和eNB B在接口建立的过程中，eNB A在向eNB B发起接口建立请求时，会将eNB A所覆盖范围内的所有服务小区的相关信息，如物理小区标识(Physical-layer Cell Identity，PCI)、接入网小区全球标识(E-UTRAN Cell Global Identifier，E-CGI)，公共陆地移动网络(Public Land Mobile Network，PLMN)等信息，发送给eNB B，相应的，eNB B在接到上述信息后，会将eNBB所覆盖范围内的所有服务小区的相关信息反馈给eNB A，这就使得相邻的eNB A和eNBB之间的接口上需要传递的消息太多，一些对对端无用的信息也在接口进行传递，给接口上的信息传输增加了很大的压力。
综上，现有技术中在相邻基站间接口建立时存在接口需要传递的消息过多，从而导致接口消息传输压力较大的技术问题。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
本申请实施例中的基站间接口建立的方法，可以应用于第一基站，也可以应用于第二基站，其中第一基站和后续的第二基站均可以属于LTE系统。
本申请实施例中的基站间接口建立的方法可以但仅限不应用于LTE系统，该方法对其他系统也同样适用。并且本申请实施例中的“第一、第二、第三”等字样仅是便于区分， 并不用于任何的限定。
下面结合附图对本申请优选的实施方式进行详细的说明。
实施例一
如图1所示，本申请实施例提供了一种基站间接口建立的方法，该基站间接口建立的方法可以应用于第一基站中，该方法的过程可以描述如下：
S100：获取第二基站的IP地址。
本申请实施例中，第一基站可以获取第二基站的IP地址，也可以获取的是第二基站的传输层地址。而在具体实施过程中，第一基站获取第二基站的IP地址的方式不仅限于以下两种：
方式一、第一基站可以从操作管理维护(Operation Administration and Maintenance，OAM)实体获取由OAM通过网管协议配置给第二基站的IP地址。
在实际应用中，网管协议可以由一系列协议组和规范组成，可以提供一种从网络上的设备中收集网络管理信息的协议。OAM可以通过网管协议给第二基站配置IP地址或者传输层地址，然后第一基站可以通过向OAM调用或者信息传递的方式获取第二基站的IP地址。
方式二、第一基站可以接收位于第一基站的覆盖区域内的终端设备上报的目标小区的标识信息，该目标小区为第二基站的覆盖区域内的小区，且该目标小区不在第一基站的邻区关系表内。根据目标小区的标识信息，第一基站可以通过核心网获取第二基站的IP地址。
其中，终端设备可以是手机、平板电脑等终端，第一基站的覆盖区域可以是第一基站的基站信号所能覆盖的地理范围，相应的，第二基站的覆盖区域可以是第二基站的基站信号所能覆盖的地理范围；第一基站的邻区关系表可以是当前第一基站已经添加并保存了的小区的相关信息表，邻区关系表中可以包括各个小区的相关信息，如小区的物理层ID、接入网小区全球标识(E-UTRAN Cell Global Identifier，E-CGI)，公共陆地移动网络(Public Land Mobile Network，PLMN)、频点、带宽以及天线端口等信息。目标小区的标识信息可以是小区的物理小区标识(Physical-layer Cell Identity，PCI)，或者可以是小区的ID、或者也可以是E-CGI等信息。
在实际应用中，首先，第一基站会收到其覆盖区域内的终端设备或者用户设备(User Equipment，UE)上报的测量报告，该测量报告中可以包括第二基站下的某个小区(本申请实施例中后续称该某个小区为目标小区)的标识信息，而第一基站在之前并没有保存过该目标小区的相关信息，即该目标小区并不在第一基站的邻区关系表内。这时，第一基站决定添加目标小区到第一基站的邻区关系表内，然后第一基站可以根据该目标小区的E-CGI，通过核心网获取第二基站的IP地址或者传输层地址，即第二基站为目标小区的服务基站。
S200：基于第二基站的IP地址向第二基站发送请求消息。
本申请实施例中，请求消息可以包括第一基站的位置相关信息，该第一基站的位置相关信息至少能够指示第一基站的覆盖区域，比如，该位置相关信息可以为与第一基站的地理位置相关的信息，第二基站可以根据该第一基站的位置相关信息，确定出第一基站在地理上所覆盖的范围；或者，该位置相关信息也可以是与第一基站的IP地址或者传输层地址相关的信息，第二基站也可以根据第一基站的传输层地址确定第一基站在传输层的相关位置等。
可能的实施方式中，请求消息还可以包括目标小区的标识信息，其中，目标小区的服务基站可以是第二基站，相应的，目标小区的标识信息可以是小区的物理小区标识，或者可以是小区的ID、或者也可以是E-CGI等信息。
可能的实施方式中，根据S100中获取第二基站的IP地址的不同方式，第一基站向第二基站发送请求消息的情况也不仅限于以下两种：
情况一、在S100中若第一基站是通过方式一获取的第二基站IP地址，则第一基站可以向第二基站发送包括第一基站的位置相关信息的请求消息。
情况二、在S100中若第一基站是采用方式二获取的第二基站的IP地址，则第一基站可以向第二基站发送包括目标小区的标识信息的请求消息。
S300：接收第二基站基于请求消息返回的响应消息，响应消息中至少包括第二基站下的部分小区的小区配置信息，以在第一基站和第二基站间建立X2/Xn接口。
本申请实施例中，小区配置信息可以包括小区的物理层ID、小区E-CGI、频点、带宽以及天线端口等信息。第二基站覆盖的全部小区可以是第二基站的基站信号覆盖范围内且已经添加到第二基站的邻区关系表中的所有小区，比如第二基站覆盖范围内有6个小区，该6个小区中的每个小区的配置信息都可以包括物理层ID、小区E-CGI、频点、带宽以及天线端口等信息。而第一基站和第二基站间的X2/Xn接口，可以是第一基站和第二基站之间的互连接口，可以支持数据和信令的直接传输，该X2/Xn接口也可以用于支持激活模式的终端设备移动、转发分组数据及多个小区的无线资源管理。
举例来说，第一基站接收到的第二基站基于请求消息返回的响应消息中可以包括第二基站下的部分小区的小区配置信息，该部分小区可以是与第一基站的覆盖区域相邻的小区，或者也可以是第一基站的覆盖区域和第二基站的覆盖区域之间重叠区域内的小区等，使得在第一基站和第二基站建立X2/Xn接口时，不存在接口需要传递的消息过多，从而导致接口消息传输压力较大的技术问题，实现了降低基站间接口消息传输压力的技术效果。
当然，在接口建立过程中，第一基站接收到的第二基站基于请求消息返回的响应消息中可以包括第二基站下的全部小区的小区配置信息。
后续，在接口更新过程中，该方法还包括：
向所述第二基站发送更新请求消息，接收所述第二基站返回的更新响应消息，所述更新响应消息中至少包括所述第二基站下的部分小区的更新后的小区配置信息。
可选地，向所述第二基站发送的更新请求消息中包括：位于所述第一基站的覆盖区域内的目标小区的标识信息，所述目标小区为所述第二基站的覆盖区域内的小区。
在实际应用中，可能第二基站覆盖范围较小，即第二基站下的小区数量较少，这时，第二基站根据第一基站发送的请求消息确定本基站下的部分小区时可能确定的是第二基站下的所有小区，这时，第一基站接收的第二基站返回的响应消息中，可以包括第二基站下的小区的配置信息。即第二基站是根据第一基站发送的请求消息确定本基站下在返回响应消息中需要携带的小区的配置信息的，达到了使得接口传输的信息更加准确的技术效果。
可能的实施方式中，可以根据S200中第一基站基于第二基站的IP地址向第二基站发送请求消息的两种不同的情况，第一基站接收第二基站基于请求消息返回的响应消息的情况也可以分为但不仅限于以下两种：
a)响应消息包括的部分小区的小区配置信息为第二基站基于请求消息中的位置相关信息所确定的信息。
若第一基站向第二基站发送的请求消息中包括第一基站的位置相关信息，则第二基站可以根据该位置相关信息判断本基站下哪些服务小区的信息需要通知给第一基站，然后，第二基站会在返回给第一基站的响应消息中携带这些服务小区的配置信息，因此，第一基站接收的第二基站返回的响应消息中可以包括部分小区的小区配置信息。
举例来说，第一基站向第二基站发送的请求消息中包括的位置相关信息可以指示第一基站的基站信号的覆盖范围，如位置相关信息所指示的覆盖范围可以是以第一基站的位置为圆点，半径为500m的圆形的覆盖范围，第二基站在收到该位置相关信息后，可以根据第二基站自身的覆盖范围确定与第一基站的覆盖范围相邻位置的一个或者多个服务小区为部分小区，即第二基站在返回给第一基站的响应消息中会包括部分小区的小区配置信息。
或者，第二基站在收到上述位置相关信息后，可以根据第二基站自身的覆盖范围确定与第一基站的覆盖范围之间重叠区域的小区为部分小区，相应的，在后续第二基站返回给第一基站的响应消息中会包括该部分小区的小区配置信息。即本申请实施例中，第一基站通过在向第二基站发送的请求消息携带第一基站的位置相关信息，使得第二基站可以通过该位置相关信息判断需要在反馈给第一基站的响应消息中携带的部分小区的小区配置信息，这样就不需要传递所有小区的配置信息，从而避免了无用信息在接口的传递。
b)响应消息包括的部分小区的小区配置信息为第二基站基于请求消息中的目标小区的标识信息所确定的信息。
若第一基站向第二基站发送的请求消息中包括目标小区的标识信息，则第二基站可以根据该目标小区的标识信息判断本基站下哪些服务小区的信息需要在X2/Xn接口建立的响应消息中携带以发送给第一基站的，然后，第二基站会在返回给第一基站的响应消息中携带这些服务小区的配置信息，因此，第一基站接收的第二基站返回的响应消息中可以包括部分小区的配置信息。
在实际应用中，第一基站覆盖范围内的终端设备检测到第二基站下的目标小区的标识信息时会上报给第一基站，且第一基站在之前并没有保存过该目标小区的信息，然后第一基站会在向第二基站发送的请求消息中携带该目标小区的标识信息，第二基站在收到该请求消息后，会根据目标小区的标识信息判断本基站下哪些服务小区的信息需要在X2/Xn接口建立的响应消息中携带以发送给第一基站的，如第二基站可以根据目标小区的标识信息确定目标小区在第二基站覆盖范围内的位置，然后确定该位置周围的其他服务小区的配置信息，其中，该其他服务小区即为本申请实施例中的部分小区。因此，第二基站在返回第一基站的响应消息中可以携带这些部分小区的小区配置信息，以在第一基站和第二基站间建立X2/Xn接口。
即本申请实施例中，第一基站通过在向第二基站发送的请求消息携带第二基站下的目标小区的标识信息，使得第二基站可以通过该目标小区的标识信息判断需要在反馈给第一基站的响应消息中携带的部分小区的小区配置信息，这样就不需要传递第二基站下所有小区的配置信息，从而避免了无用信息在接口的传递。
可能的实施方式中，第一基站接收的响应消息中还可以包括第二基站的位置相关信息和第二基站的覆盖范围信息。其中，位置相关信息可以指示第二基站当前所处的地理位置，而第二基站的覆盖范围信息可以指示第二基站下可以涵盖的小区数量。在实际应用中，第二基站的位置相关信息和第二基站的覆盖范围信息可以根据实际情况，如X2/Xn接口所能够承受的信息传输量等因素，来确定是否在反馈给第一基站的响应消息中进行携带，本申请实施例中不作具体限制。
下面，本申请实施例将通过举例来说明基站间接口建立的方法在实际应用中的应用场景。
场景一：假设第一基站和第二基站可以互为相邻基站。因此，通过OAM方式建立第一基站和第二基站间X2/Xn接口的流程可以如下：
首先，OAM可以通过网管协议给第二基站配置IP地址(或者传输层地址)，第一基站可以从OAM获取第二基站的IP地址。然后，第一基站可以根据第二基站的IP地址向第二基站发起X2/Xn接口建立的请求消息，该请求消息中可以携带第一基站的位置相关信息、覆盖范围信息等。
然后，第二基站在接收请求消息后，可以根据请求消息中包括的第一基站的位置相关 信息判断本基站下哪些服务小区的信息需要通知给第一基站的，可以将这些服务小区的配置信息放入响应消息中。
最后，第一基站可以接收的第二基站基于所述请求消息中的位置相关信息返回的响应消息，该响应消息中就只包括第二基站下的部分小区的小区配置信息，从而实现第一基站和第二基站间X2/Xn接口的建立。
场景二：第一基站和第二基站也可以通过自动邻区关系(Auto Neighbor Relationship，ANR)方式建立X2/Xn接口，其建立过程可以如下：
首先，第一基站收到来自终端设备的测量报告(终端设备当前驻留在第一基站的某个小区下)，该测量报告中包含了第二基站下某个小区(后续称为目标小区)的标识信息，第一基站发现其在之前并没有保存过该目标小区的配置信息，第一基站和该目标小区所在的基站第二基站之间还没有建立X2/Xn接口，第一基站决定与第二基站建立X2/Xn接口。
然后，第一基站可以根据目标小区的标识信息获取该目标小区的服务基站，即第二基站的IP地址。第一基站根据该第二基站的IP地址向第二基站发送请求消息，该请求消息中可以包括目标小区的标识信息。
第二基站在收到该请求消息后，会根据目标小区的标识信息判断本基站下哪些服务小区的信息需要在X2/Xn接口建立的响应消息中携带以发送给第一基站的，如第二基站可以根据目标小区的标识信息确定目标小区在第二基站覆盖范围内的位置，然后确定该位置周围的其他服务小区的配置信息，其中，该其他服务小区即为本申请实施例中的部分小区。因此，第二基站在返回第一基站的响应消息中可以携带这些部分小区的小区配置信息，以在第一基站和第二基站间建立X2/Xn接口。

可能的实施方式中，所述第一获取模块10还可以用于接收位于所述第一基站的覆盖区域内的终端设备上报的目标小区的标识信息，所述目标小区为所述第二基站的覆盖区域内的小区，且所述目标小区不在所述第一基站的邻区关系表内；基于所述目标小区的标识信息，通过核心网获取所述第二基站的IP地址。
可能的实施方式中，所述第一发送模块20可以用于基于所述第二基站的IP地址向所 述第二基站发送请求消息，所述请求消息包括所述第一基站的位置相关信息，所述第一基站的位置相关信息至少能够指示所述第一基站的覆盖区域。
可能的实施方式中，所述第一发送模块20还可以用于基于所述第二基站的IP地址向所述第二基站发送请求消息，所述请求消息包括所述目标小区的标识信息。
