Description

一种 X2配置的自动删除方法、 基站和网络系统 技术领域
本发明涉及通信技术领域， 特别涉及一种 X2配置的自动删除方法、 基站 和网各系统。 背景技术
在长期演进 ( long term evolution, LTE )系统中，基站（ enhanced NodeB , eNodeB )之间可以通过 X2接口进行通信。 目前 LTE协议支持 X2接口自动建 立功能， 但对 X2接口自动删除功能没有定义。 随着 LTE网络的动态变化， 已 经建立的 X2接口可能变为冗余配置， 如果没有及时清理这些配置， 可能导致 冗余数据占用了现有的 X2接口配置规格， 导致新的 X2接口无法加入。
请参阅图 1所示的基站系统示意图， 该图给出了产生冗余 X2配置的一种 场景， 具体如下：
网络建设初期， eNodeB A和 eNodeB B首先开通， 这两个站点之间通过
X2自建立流程建立起了 eNodeB A与 eNodeB B之间的 X2接口。 网络建设一 般都会采用插花建站的方式进行， 假如后续开通了 eNodeB C , 该 eNodeB C 开通以后， 图 1所示 3个基站之间的覆盖关系将会发生变化： X2 自建立功能 将分别建立 eNodeB A到 eNodeB C的 X2接口， 以及 eNodeB C到 eNodeB B 的 X2接口。 这时， 之前建立的 eNodeB A到 eNodeB B之间的 X2接口则变为 冗余的 X2配置。需要清理掉 eNodeB A到 eNodeB B之间的 X2接口对应的配 置数据。
如果采用手动清理冗余的 X2配置， 则会耗费大量的人力， 目前一般可以 通过集中式的方案来实现自动清理冗余的 X2配置， 该方案实现的前提是网络 中的 eNodeB都由同一个网管管理

为了使本发明的目的、技术方案和优点更加清楚， 下面将结合附图对本发 明作进一步地详细描述， 显然， 所描述的实施例仅仅是本发明一部份实施例， 而不是全部的实施例。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， 都属于本发明保护的范围。
本发明实施例提供了一种 X2配置的自动删除方法， 如图 2所示， 包括：
201 : 第一基站获取第二基站的邻区配置数据；
第一基站获取第二基站的邻区配置数据的方式， 可以是采用 X2接口协议 消息， 例如： 36.423中的 X2建立请求（ X2 SETUP REQUEST )、 X2建立响应 ( X2 SETUP RESPONSE )、 基站配置更新 （ ENB CONFIGURATION UPDATE ); 可以理解的是第二基站可以是一个基站也可以是一个以上的基站， 若第二基站是一个以上的基站， 每个基站作为一个独立的个体执行 X2配置的 自动删除方法的方案与一个的时候是相同的。
上述邻区配置数据是基站的邻区信息，从邻区配置数据中可以获知本基站 的邻区是否为空， 为空也即是一个邻区也没有。上述邻区配置数据可以采用邻 区关系列表的形式来体现， 以下作为一个举例， 假定 eNodeB A为第一基站， eNodeB B为第二基站， 请参阅表 1 , 为第二基站的邻区配置数据的一个举例： 表 1
Figure imgf000009_0001
上述表 1最后一行， 也可以没有。 表 1可以表示从基站 B到基站 A的小 区的邻区为空，从基站 B到基站 C的小区的邻区有 m个。对于一个基站而言， 基站可以知道的是本基站的邻区配置数据，也即本基站到对端基站的小区的邻 区是否为空的信息是可以从邻区配置数据中获知的。
进一步地，在获取到第二基站的邻区配置数据之后， 第二基站后续发送的 邻区配置数据可以是仅发送发生变化了的部分， 也即邻区配置数据的更新信 息； 具体地： 步骤 201之后， 还包括： 为上述第二基站的每个小区保存用于标 识是否配置第一基站为邻区的标识位；若第一基站接收到上述第二基站的邻区 配置数据的更新信息， 则使用上述更新信息更新上述标识位。
202: 第一基站依据上述第一基站的邻区配置数据以及上述第二基站的邻 区配置数据， 确定第一基站与第二基站之间是否存在邻区关系；
具体地，第一基站依据上述第一基站的邻区配置数据以及上述第二基站的 邻区配置数据，确定第一基站与第二基站之间是否存在邻区关系可以为： 第一 基站依据第一基站的邻区配置数据确定第一基站到上述第二基站的所有小区 的邻区是否为空，并且依据上述第二基站的邻区配置数据确定第二基站到上述 第一基站的所有小区的邻区是否为空；若均为空则确定第一基站与第二基站之 间不存在邻区关系
按照前述举例，第一基站可以由第一基站的邻区配置数据获知第一基站到 第二基站的所有小区的邻区是否为空；第一基站可以由接收到的第二基站的邻 区配置数据确定第二基站到上述第一基站的所有小区的邻区是否为空。具体确 定的方案可以参考上表 1的方案，对于第一基站和第二基站的邻区配置数据的 具体确定方法是相同的在此不再赘述。
203: 若第一基站与第二基站之间不存在邻区关系， 则删除上述第一基站 与第二基站之间的 X2接口对应的 X2配置数据。
可以理解的是， 如果两者中有一个不为空， 那么 X2配置数据不是冗余数 据不需要删除 X2配置数据。
以上方案第一基站可以获取到第二基站的邻区配置数据，在依据第一基站 的邻区配置数据确定第一基站到上述第二基站的所有小区的邻区为空，并且据 上述第二基站的邻区配置数据确定第二基站到上述第一基站的所有小区的邻 区为空时，删除上述第一基站与第二基站之间的 X2接口对应的 X2配置数据。 实现了冗余的 X2配置数据的自动删除，并不需要第一基站和第二基站共网管， 实现分布式的 X2配置数据管理， 应用场景更广泛。
进一步地， 为了减小 X2配置数据误删的风险， 本发明实施例还提供了如 下方案： 在 203中， 确定均为空之后， 在删除上述第一基站与第二基站之间的 X2接口对应的 X2配置数据之前还包括： 启动老化定时器， 在上述老化定时 器超时后， 若第一基站到上述第二基站的所有小区的邻区保持为空， 并且第二 基站到上述第一基站的所有小区的邻区也保持为空，则执行上述删除上述第一 基站与第二基站之间的 X2接口对应的 X2配置数据。
本实施例通过采用老化定时器的方案，可以在定时器超时期间监控第一基 站和第二基站分别到对端的所有小区的邻区是否均保持为空，也即这种保持为 空是一个稳定的状态， 这时可以确定第一基站和第二基站之间的 X2接口是冗 余的准确率将会更高， 因此可以减小 X2配置数据误删的风险。
进一步地， 为了保持第一基站和第二基站删除 X2配置数据的同步， 本发 明实施例还提供了如下方案：在执行上述删除上述第一基站与第二基站之间的 X2接口对应的 X2配置数据之前还包括： 向上述第二基站发送第一消息，在把上述第一基站全量的邻区配置数据发 送给上述第二基站的同时，请求上述第二基站返回上述第二基站全量的邻区配 置数据，依据上述第二基站全量的邻区配置数据确定上述第二基站到上述第一 基站的所有小区的邻区是否为空， 若是， 则删除上述第一基站与第二基站之间 的 X2接口对应的 X2配置数据。 同理， 第二基站依据上述第一基站全量的邻 区配置数据确定上述第一基站到上述第二基站的所有小区的邻区是否为空，若 是， 则删除上述第一基站与第二基站之间的 X2接口对应的 X2配置数据。
上述全量的邻区配置数据，是相对于邻区配置数据的更新信息而言的； 更 新信息是邻区配置数据发生变化了的部分，全量的邻区配置数据是基站全部的 邻区配置数据。
本实施例通过 X2第一消息的机制进行全量邻区交互和确认， 通过该消息 可以触发 X2接口的本端和对端 （即第一基站和第二基站） 同时执行 X2配置 数据的删除动作。从而可以避免因删除的时间不一致而导致的传输底层链路告 可以理解的是， 第一基站可以接收其他基站的邻区配置数据， 第一基站也 可以将本端的邻区配置数据发送给其他基站，以供其他基站来自动确定是否删 除相应的 X2配置数据， 具体方案如下： 上述方法还包括：
上述第一基站向上述第二基站发送上述第一基站的邻区配置数据和 /或上 述第一基站的邻区配置数据的更新信息。
另需说明的是，第一基站也可以不借助于第二基站的邻区配置数据来确定
X2接口是否冗余， 进而删除冗余的 X2配置数据。 还可以采用的方案例如： 通过确定两个基站间的传输层在设置定时间内是否有数据传输，如果没有数据 发送， 则确定上述两个基站间的 X2接口是冗余的， 然后可以删除上述 X2接 口对应的 X2配置数据； 或者， 确定 X2接口的数据链路在设定时间是否有数 据传输， 如果没有数据传输， 则确定上述两个基站间的 X2接口是冗余的， 然 后可以删除上述 X2接口对应的 X2配置数据。
另外， 可以对第一基站中所有的 X2接口执行以上方案， 那么 X2配置数 据的自动删除方法属于自组织网络（ Self-Organized Network, SON )的一种方 案， 如果希望由人工管理网络中的 X2配置， 不希望全部交给 SON自动管理， 可以通过开关进行控制，开关可以设置成 eNodeB级别的。具体地： 对 eNodeB 下的 X2配置， 如果用户希望部分交给 SON管理， 部分由人工管理， 可以通 过配置 X2白名单的方法来实现。 对于配置在 X2白名单中的 X2配置数据， X2自动删除方案不会处理这一类 X2配置数据。
基于以上实施例的介绍， 本发明实施例还给出了更为详细的方案举例， 该 方案中， 第一基站的每个 X2对端的第二基站的每个小区都使用邻区标识位来 表示该小区是否为第一基站的邻区， 并给出了一个可选的执行时序方案， 可以 理解的是确定小区是否为邻区的标识方法并不一定需要使用邻区标识位来表 示，后续的时序也仅是众多执行时序的一个举例， 均不应理解为对本发明实施 例的限定， 请参阅图 3所示， 包括：
301 : 对某条 X2接口初始化第一基站的邻区标识位， 初始置为 1 ;
假定上述 X2接口的两端分别为第一基站到第二基站， 那么首先将上述第 二基站的所有小区（假定有编号为 1~111的小区）的邻区标志位都设置为 1 ,即： 第二基站的所有小区均设置第一基站为邻区； 如下表 2所示：
表 2
Figure imgf000012_0001
302: 在第一基站获取到第二基站的邻区配置数据后， 第一基站更新邻区 标识位；
第一基站接收邻区配置数据的方式，可以是采用 X2接口协议消息，例如： 36.423中的 X2建立请求（ X2 SETUP REQUEST )、 X2建立响应 （ X2 SETUP RESPONSE ), 基站配置更新（ENB CONFIGURATION UPDATE ), 来获取第 二基站的邻区配置数据；可以理解的是第二基站可以是一个基站也可以是一个 以上的基站， 若第二基站是一个以上的基站，每个基站作为一个独立的个体执 行 X2配置的自动删除方法的方案与一个的时候是相同的。
具体地， 假如收到的邻区配置数据如表 3所示： X2接口的一端 X2接口的另一端 对端小区 邻区标识位 第一基站 第二基站 2 0
第一基站 第二基站 , , , 0
该表 3中可以仅包含发生改更的邻区标志位 ,其中邻区标识位为 0表示该 邻区标识位对应的小区没有配置第一基站为邻区， 在接收到表 3 以后， 表 1 会更新为表 4, 如下：
表 4
Figure imgf000013_0001
若后来又接收到了表 5的邻区配置数据， 表 5如下所示:
表 5
Figure imgf000013_0002
这时在第一基站的邻区配置数据的表应该更新为表 6, 如下:
表 6
Figure imgf000013_0003
从表 6中可以看出， 第二基站到第一基站的所有小区的邻区均为空， 即第 二基站下的小区全部都没有配置第一基站为邻区。
303: 第一基站判断是否满足： 第一基站到第二基站所有小区的邻区为空, 且第二基站所有小区到第一基站所有小区的邻区为空；如果均为空，进入 304, 否则， 进入 306;
依据上表 6可知， 第二基站所有小区到第一基站所有小区的邻区为空； 第 一基站到第二基站所有小区的邻区是否为空的判断方案，可以参考第二基站所 有小区到第一基站所有小区的邻区是否为空的方案， 在此不再赘述。
304: 判断 X2老化定时器是否正在运行， 如果是， 进入 302; 如果否， 进 入 305;
305: 启动 X2老化定时器， 开始计时， 并进入 302;
306: 判断 X2老化定时器是否正在运行， 如果是， 进入 307; 如果否， 进 入 302;
307: 停止老化定时器， 即停止计时。
通过以上图 3方案， 可以获知到的结果是： 第一基站到第二基站所有小区 的邻区为空，且第二基站所有小区到第一基站所有小区的邻区为空， 以及两者 均为空的状态在定时器计时过程中是否一致保持着。 基于以上方案， 具体 X2 配置数据删除的控制方案， 请参阅图 4, 包括：
401 : 判断老化定时器是否超时， 如果没有， 就继续判断， 如果超时进入
402; 可以理解的是， 本步骤也可以不用采用循环判断的方式实现， 例如： 还 可以是老化定时器超时时发出触发进入 402步骤的信号来进入 402;
上述定时器计时的时长可以是固定的，也可以是定时器接收到外部设备发 402: 通过 X2 的第一消息交互第一基站和第二基站的邻区配置数据， 并 更新邻区标识位；
邻区标识位的具体更新方案请参阅前述实施例中表 4和表 6的刷新示例， 此处不再赘述。
在该步骤中，第一基站发送给第二基站的第一消息可以不但包含请求上述 第二基站返回上述第二基站全量的邻区配置数据的指示，还可以包含第一基站 的所有全量邻区配置数据；将第一基站的所有全量邻区配置数据发送给第二基 站，可以方便第二基站也执行与第一基站相同的方案来确定是否要删除对应的 X2配置数据。
403: 第一基站判断是否满足： 第一基站到第二基站所有小区的邻区为空， 且第二基站所有小区到第一基站所有小区的邻区为空；也即判断第一基站和第 二基站下的所有小区到 X2接口的对端的邻区均为空， 如果是， 进入 404, 如 果否， 进入 405;
404: 删除 X2配置数据；
405: 停止老化定时器。
以上方案第一基站可以获取到第二基站的邻区配置数据，在依据第一基站 的邻区配置数据确定第一基站到上述第二基站的所有小区的邻区为空，并且据 上述第二基站的邻区配置数据确定第二基站到上述第一基站的所有小区的邻 区为空时，删除上述第一基站与第二基站之间的 X2接口对应的 X2配置数据。 实现了冗余的 X2配置数据的自动删除，并不需要第一基站和第二基站共网管， 实现分布式的 X2配置数据管理， 应用场景更广泛。
本实施例通过采用老化定时器的方案，可以在定时器超时期间监控第一基 站和第二基站分别到对端的所有小区的邻区是否均保持为空，也即这种保持为 空是一个稳定的状态， 这时可以确定第一基站和第二基站之间的 X2接口是冗 余的准确率将会更高， 因此可以减小 X2配置数据误删的风险。
本实施例通过 X2第一消息的机制进行全量邻区交互和确认， 通过该消息 可以触发 X2接口的本端和对端 （即第一基站和第二基站） 同时执行 X2配置 数据的删除动作。从而可以避免因删除的时间不一致而导致的传输底层链路告 本发明实施例还提供了一种基站， 如图 5所示， 包括：
