在 LTE阶段, 由于基站覆盖半径相对于传统网络架构中的基站覆盖半径缩小, 因此基 站的密度需要增大, 相应的承载网中的承载节点数也将增加, 同时, 由于相邻基站之间都 需要直接通信, 因此在承载网上提供的相邻基站的通信连接的数量将会非常多, 即 X2 接 口需要建立的连接数将会非常多。 现有的技术方案是采用静态配置的方式来完成相邻基站 在承载网上的连接建立。 承载网事先需要获知基站的相邻关系, 并通过承载网的网管系统 对承载网完成电路连接的配置, 以实现相邻基站之间的相互通信。

图 6是本发明实施例提供相邻基站连接的建立设备的另一结构示意图。 具体实施方式 本发明实施例提供一种相邻基站连接的建立方法、 建立设备和建立系统。 以下分别进 行详细说明。
实施例一、
本发明将从相邻基站连接的建立设备的角度进行描述, 该相邻基站连接的建立设备作 为承载网中的承载节点。
一种相邻基站连接的建立方法, 包括: 承载节点获取基站在承载网上的接入信息, 根 据获取到的接入信息获取基站的相邻信息, 根据得到的相邻信息建立相邻基站的连接。 如 图 1所示, 具体流程可以如下:
101、 承载节点获取基站在承载网上的接入信息;
该接入信息具体可以为基站与承载节点的连接关系, 承载节点可以通过获取与该承载 节点连接的基站的基站标识信息, 然后根据获取到的基站标识信息保存和维护基站与承载 节点的连接关系, 从而得到基站在承载网上的接入信息。
承载节点还可以获取所有基站在承载网上的接入信息, 例如, 承载节点发送获取到的 基站标识信息给承载网上的其他承载节点, 并接收承载网上的其他承载节点发送的基站标 识信息, 根据获取到的基站标识信息以及接收到的基站标识信息保存并维护基站与承载节 点的连接关系, 即此时承载节点上保存了所有基站与承载网中各个承载节点的连接关系, 即得到了所有基站在承载网上的接入信息。
当然, 除了上述所说的获取基站标识信息之外, 还可以通过获取其他可以反映基站在 承载网上的接入情况的信息, 然后通过在承载网内部将该获取到的信息进行传递扩散来得 到所有基站在承载网上的接入信息。
102、 承载节点根据获取到的接入信息获取基站的相邻信息;
例如, 具体可以根据获取到的接入信息和与该承载节点连接的基站建立通信连接, 然 后通过建立的通信连接与基站进行信息交互, 以获取该基站的相邻信息。
承载节点还可以获取所有基站的相邻信息, 例如, 承载节点发送获取到的相邻信息给 承载网上的其他承载节点, 并接收承载网上的其他承载节点发送的其他承载节点获取的相 邻信息, 保存并维护获取到的相邻信息以及接收到的相邻信息。
为了动态的反映网络的实时变化, 还可以根据预置的策略对相邻信息进行更新, 然后 根据更新的基站的相邻信息更新相邻基站的连接, 例如, 当网络中新增一个基站时, 则可 以根据更新的基站的相邻信息建立该基站的相邻基站的连接, 减少某个基站时, 则删除所 有与该减少的基站相关的相邻基站的连接, 而当基站没有发生改变, 而仅仅是基站的相邻 信息发生变化时, 则根据变化的相邻信息新建或删除对应的相邻基站的连接; 当然, 也可 以在网络发生变化时, 完全更新所有相邻基站的连接。 其中, 对相邻信息进行更新时可采 用如下任一方式:
周期性与基站进行信息交互, 以更新基站的相邻信息; 或者, 在基站邻居关系发生变化时, 接收基站上报的更新的基站的相邻信息。
103、 承载节点根据获取到的接入信息和相邻信息建立相邻基站的连接;
建立的方式可以采用现有技术中的任意一种方式, 比如, 可以由网管设备创建相邻基 站的连接, 或者, 也可以由承载节点自动创建相邻基站的连接, 即由承载节点根据获取到 的接入信息和相邻信息向承载网发起相邻基站的连接建立请求, 以便承载网根据接收到的 连接建立请求建立相邻基站的连接;
其中, 在由网管设备创建相邻基站的连接时, 承载节点可以主动上报获取到的接入信 息和相邻信息给网管设备, 也可以在接收到网管设备的查询后, 才发送获取到的接入信息 和相邻信息给网管设备, 以便网管设备根据这些接入信息和相邻信息建立相邻基站的连 接。
需说明的是, 在建立相邻基站的连接时, 如果对连接有特殊的要求, 比如对带宽、 时 延或服务质量 (QoS, Qual ity of Service ) 有特定的要求的话, 还可以对连接属性进行 预先设置, 然后在需要建立相邻基站的连接时, 就可以根据获取到的接入信息和相邻信息 按照预置的连接属性建立相邻基站的连接。
由上可知, 本实施例采用动态地获取所有基站在承载网上的接入信息, 根据接入信息 获取基站的相邻信息, 以此来建立相邻基站的连接, 从而无需花费大量的人力物力和时间 来对相邻基站的连接进行静态配置, 可以提高网络建网的效率、 降低运营和维护的复杂度 和降低运营和维护的成本。
实施例二、
根据实施例一所描述的方法, 本实施例将举例作进一步详细说明。
在承载节点与基站间, 增加一个通信协议接口, 使得承载节点可以获知与其连接的基 站的基站标识信息, 比如基站的标识 (ID, Identity) 或基站的网际协议 (IP, Internet Protocol ) 地址等, 并在后续也可以通过该通信协议接口获取基站的相邻信息; 其中, 基 站标识信息具体的获取方式可根据不同的网络技术与连接方式, 采用不同的方案, 当然, 在获取基站标识信息时也可以不通过该增加的通信协议接口, 比如采用侦听或监控接入基 站的 IP地址等方式来获取。
在承载节点获取到与其连接的基站的基站标识信息后, 在承载网内部将获取到的基站 标识信息进行传递以扩散到其它承载节点上, 同时接收承载网中其他承载节点传送来的基 站标识信息, 根据自身获取到的基站标识信息以及接收到的其他承载节点传送过来的基站 标识信息保存并维护基站和各承载节点的连接关系, 基于此, 承载节点就可以知道与承载 网连接的所有基站与各个承载节点的连接关系, 即承载节点可以获取到所有基站在承载网 上的接入信息。
承载节点获取到所有基站在承载网上的接入信息后, 可以根据该接入信息获取基站的 相邻信息, 例如, 承载节点可以根据该接入信息与基站建立通信连接, 然后通过建立的通 信连接与基站进行信息交互, 以此来获取基站的相邻信息, 并保存该相邻信息。 为适应基 站网络的动态变化, 承载节点与基站之间可周期性地进行信息交互以对保存的相邻信息进 行更新, 或者, 基站可以根据基站邻居关系的变化, 事件触发式地将基站的相邻信息发送 给承载节点。 需说明的是, 基站上需要保存基站间的相邻信息, 该相邻信息可基于网络规 划部署, 由人工将确定的相邻信息在各个基站上进行配置和保存, 也可以由基站通过自动 邻居发现协议动态地发现基站的相邻信息, 然后保存在基站上并进行维护。
承载节点获取到基站的相邻信息后, 将这些相邻信息在承载网内进行传递扩散, 同时 接收承载网中其他承载节点传送来的基站的相邻信息 (即其他承载节点获取到的基站的相 邻信息) , 并对这些相邻信息 (包括自身获取的基站的相邻信息, 以及从其他承载节点上 获取到的基站的相邻信息) 进行保存和维护。 基于此, 承载网内所有承载节点都将保存有 一张全承载网连接的基站的相邻基站信息表。
例如, 假设基站 1的 IP地址为 " 10. 0. 0. 1 " , 基站 2的 IP地址为 " 10. 0. 0. 2 " , 基站 3 的 IP地址为 " 10. 0. 0. 3 ",基站 4的 IP地址为 " 10. 0. 0. 4",基站 5的 IP地址为 " 10. 0. 0. 5 "; 基站 1的相邻基站为基站 2、 基站 3、 基站 4和基站 5; 基站 2的相邻基站为基站 1、 基站 3、 基 站 4和基站 5; 基站 3的相邻基站为基站 1、 基站 2、 基站 4和基站 5; 基站 4的相邻基站为基站 1、 基站 2、 基站 3和基站 5 ; 基站 5的相邻基站为基站 1、 基站 2、 基站 3和基站 4; 则每个承 载节点上保存的基站的相邻基站信息表可以如表一所示;
Figure imgf000007_0001
由于承载节点具有了基站的相邻关系和基站在承载网上的接入信息, 因此承载网可据 此, 采用相应的控制协议, 比如采用通用多协议标记交换 (GMPLS , Generalized Multiprotocol Label Switching) 协议等建立相邻基站连接, 即 X2连接, 此后还可以根 据基站相邻关系的变化进行相邻基站连接的动态管理, 例如, 当网络中新增一个基站时, 则可以根据更新的基站的相邻信息建立该基站的相邻基站的连接, 减少某个基站时, 则删 除所有与该减少的基站相关的相邻基站的连接, 而当基站没有发生改变, 而仅仅是基站的 相邻信息发生变化时, 则根据变化的相邻信息新建或删除对应的相邻基站的连接; 当然, 也可以在网络发生变化时, 则完全更新所有相邻基站的连接, 等等, 通过对相邻基站连接 的动态管理, 可以实现相邻基站连接的动态建立与维护, 实现提高网络建网的效率和降低 运维成本的目的。
以下将以一个具体的例子作详细说明。
参见图 3, 假设承载网中具有承载节点 A和承载节点 B, 基站 1与基站 2连接在承载节点 A 上, 基站 3连接在承载节点 B上, 其中, 基站 1与基站 2为邻居关系, 基站 2与基站 3为邻居关 系, 则参见图 2, 相邻基站连接的建立方法的具体流程可以如下:
201、 承载节点 A和承载节点 B检测到各自连接的基站的基站标识信息, 比如基站的 ID 或 IP, 识别出所连接的基站, 并维护基站连接表, 其中, 承载节点 A所维护的基站连接表 可参见表二, 承载节点 B所维护的基站连接表可参见表三; 如下:
表二 (承载节点 A ) :

(承载节点 B) :
Figure imgf000008_0002
202、 承载节点 A和承载节点 B将各自检测到的基站的基站标识信息 (比如 ID或 IP) 在 承载网内部进行交互, 并更新各自的基站连接表, 其中, 承载节点 A更新后的基站连接表 可以参见表四, 承载节点 B更新后的基站连接表可以参见表五, 如下:

表五 (承载节点 B) : 节点名称 连接基站信息
承载节点 B 基站 3
承载节点 A 基站 1 基站 2
203、 承载节点 A和承载节点 B分别根据步骤 202中的基站连接表与基站建立通信连接, 然后分别通过建立的通信连接与基站进行信息交互, 以获取基站的相邻信息, 各个承载节 点可以根据获取到的基站的相邻信息维护一张基站邻居关系表, 例如, 参见表六和表七, 表六为承载节点 A所维护的基站邻居关系表, 表七为承载节点 B所维护的基站邻居关系表; 表六 (承载节点 A ) :
Figure imgf000009_0001
表七 (承载节点 B)
Figure imgf000009_0002
204、 承载节点 A和承载节点 B分别将各自获取到的基站的相邻信息在承载网内部进行 扩散传递, 即各个承载节点分别将各自获取到的基站的相邻信息发送给除自身之外的其他 承载节点的同时, 也接收其他承载节点传送来的基站的相邻信息, 并且, 各个承载节点保 存和维护自身获取到的基站的相邻信息以及从其他承载节点上获取到的基站的相邻信息, 从而各个承载节点都可以获得一份完整的基站标识信息和基站的相邻信息, 例如, 在本实 施例中, 承载节点 A和承载节点 B均可以得到如表八所示的基站的接入和相邻信息表: 表八:
Figure imgf000009_0003
205、 承载节点 A和承载节点 B基于这份完整的基站标识信息和基站的相邻信息建立相 基站的连接,比如,承载节点 A和承载节点 B基于该基站的基站标识信息和相邻信息表(例 如表八) 建立相邻基站的连接, 具体的建立方式可在现有技术的基础上, 根据运营商的策 略而定, 以下只列举两种常见的建立方式:
(一) 通过网管设备创建相邻基站连接:
例如, 承载节点 A或承载节点 B可以主动将获取到的基站标识信息和基站的相邻信息上 报给承载网的网管设备, 或者也可以在承载网的网管设备向 A或承载节点 B进行查询后, 承 载节点 A或承载节点 B才将获取到的基站标识信息和基站的相邻信息上报给承载网的网管 设备, 网管设备在接收到基站标识信息和基站的相邻信息后, 便可获知承载网内的相邻基 站的承载连接需求, 即可在承载网内为相邻基站创建连接。
参见图 3的虚线部分, ①为在承载节点 A处创建的基站 1与基站 2的承载连接; ②为在承 载节点 A和承载节点 B创建的基站 2与基站 3的承载连接。
如果邻居基站关系发生变化, 则承载节点 A或承载节点 B会实时更新基站的相邻信息, 然后将更新后的基站的相邻信息上报给网管设备, 以便网管设备根据更新后的基站的相邻 信息更新相邻基站连接。 例如, 当网络中新增一个基站时, 则可以根据更新的基站的相邻 信息建立该基站的相邻基站的连接, 减少某个基站时, 则删除所有与该减少的基站相关的 相邻基站的连接, 而当基站没有发生改变, 而仅仅是基站的相邻信息发生变化时, 则根据 变化的相邻信息新建或删除对应的相邻基站的连接; 当然, 也可以在网络发生变化时, 则 完全更新所有相邻基站的连接, 等等。
在 LTE网络的承载应用场景中, 由于 X2接口主要用于相邻基站间信号切换过程中的信 息传输, 其传输的信息量并不大, 所以为简化处理, 可以统一设定相邻基站连接的连接属 性, 比如设置统一的带宽和 /或 QoS需求等, 然后承载网管设备可按该预先设置好的统一的 连接属性进行相邻基站连接的创建。
需说明的是, 如果对相邻基站连接有特殊的需要, 比如对相邻基站连接的带宽、 时延 或 QoS等有特别需求时, 也可以独立设置具体的相邻基站连接的连接属性, 具体设置该连 接属性时, 可以由基站来提供此连接属性的设置, 或者也可以由承载节点根据基站的类型 等进行设定, 在连接属性设置完毕后, 承载网管设备即可根据该具体的连接属性来进行相 邻基站连接的创建, 比如, 对时延要求高的可按最短路径策略创建; 又比如, 对带宽需求 高的, 则可重点考虑承载网带宽的利用效率, 可以按有利于提升带宽利用率的方式进行创 建, 等等。
(二) 由承载网络节点创建相邻基站连接:
如果承载网支持动态控制信令, 比如支持通用多协议标记交换 (GMPLS , General i zed Mul t iprotoco l Labe l Swi tching )等的自动交换光网络 ( ASON, Automat i cal ly Swi tching Optical Network) 网络, 则可由承载节点 A或承载节点 B在承载网内部动态的发起相邻基 站的连接建立请求, 承载网在接收到该连接建立请求后, 根据该连接建立请求动态的在承 载网内建立起相邻基站连接。
如果邻居基站关系发生变化, 则承载节点 A或承载节点 B会实时更新基站的相邻信息, 然后根据更新后的基站的相邻信息发起相邻基站的连接建立请求, 以更新相邻基站连接。 例如, 当网络中新增一个基站时, 则可以根据更新的基站的相邻信息建立该基站的相邻基 站的连接, 减少某个基站时, 则删除所有与该减少的基站相关的相邻基站的连接, 而当基 站没有发生改变, 而仅仅是基站的相邻信息发生变化时, 则根据变化的相邻信息新建或删 除对应的相邻基站的连接; 当然, 也可以在网络发生变化时, 则完全更新所有相邻基站的 连接, 等等。
与建立方式 (一) 类似, 为简化处理, 可以统一设定相邻基站连接的连接属性, 比如 设置统一的带宽和 /或 QoS需求等, 然后承载网管设备可按该预先设置好的统一的连接属性 进行相邻基站连接的创建。 但如果对相邻基站连接有特殊的需要, 比如对相邻基站连接的 带宽、 时延或 QoS等有特别需求, 则在发送相邻基站的连接建立请求时, 可以根据需求来 设置相邻基站连接的连接属性, 以创建与设置的连接属性相应的承载连接。
由上可知, 本实施例承载网中的承载节点可以获取基站的接入信息和基站的相邻信 息, 并依据该获取到的接入信息和基站的相邻信息来自动建立相邻基站的连接, 大大减少 了现有技术中对网管设备大量的配置与维护工作, 比如, 在基站停电、 基站搬迁与扩容等 场景发生时, 就可以无需花费大量的人力物力对配置数据进行重新配置以建立新的相邻基 站的连接, 因此, 采用本发明实施例所提供的方案, 可以提升了网络运维效率、 降低运营 和维护的复杂度和降低运营和维护的成本。
同时, 由于连接是网络自动创建的, 因此, 承载网可根据网络资源利用的情况, 预先 制定与网络资源相适应的策略, 然后根据该预置的策略来创建链路, 可以充分地提升网络 资源利用率。
进一步的, 由于是由网络自动创建连接, 因此在网络发生变更时, 可以避免现有技术 中由于需要人工进行静态配置所导致的配置数据调整不及时而造成的通信网络故障等问 题, 可以提升网络服务质量。
实施例三、
根据实施例一所描述的方法, 本实施例将举例作进一步详细说明。
在本实施例中, 将以由网管设备保存全网的连接情况, 并由网管设备发起建立相邻基 站的连接为例进行说明, 与实施二不同的是, 在本实施例中, 承载网中的各个承载节点在 获取到接入信息和基站的相邻信息后, 可以不在承载网内部进行扩散和传递, 即各个承载 节点可以不保存全网的连接情况, 而是直接将获取到的接入信息和基站的相邻信息上报给 网管设备, 由网管设备进行统一地调控以建立相邻基站的连接。
在承载节点与基站间, 增加一个通信协议接口, 使得承载节点可以获知与其连接的基 站的基站标识信息, 比如基站的 ID或 IP地址等, 并在后续也可以通过该通信协议接口获取 基站的相邻信息;其中,基站标识信息具体的获取方式可根据不同的网络技术与连接方式, 采用不同的方案, 当然, 在获取基站标识信息时也可以不通过该增加的通信协议接口, 比 如采用侦听或监控接入基站的 IP地址等方式来获取。
在承载节点获取到基站标识信息后, 可以根据该基站标识信息获取基站的相邻信息, 例如, 承载节点可以根据该基站标识信息与基站建立通信连接, 然后通过建立的通信连接 与基站进行信息交互, 以此来获取基站的相邻信息, 并保存该相邻信息。 为适应基站网络 的动态变化, 承载节点与基站之间可周期性地进行信息交互以对保存的相邻信息进行更 新, 或者, 基站可以根据基站邻居关系的变化, 事件触发式地将基站的相邻信息发送给承 载节点。 需说明的是, 基站上需要保存基站间的相邻信息, 该相邻信息可基于网络规划部 署, 由人工将确定的相邻信息在各个基站上进行配置和保存, 也可以由基站通过自动邻居 发现协议动态地发现基站的相邻信息, 然后保存在基站上并进行维护。
承载节点获取到基站的相邻信息后, 可以对这些相邻信息进行保存和维护。
承载网中的各个承载节点将自身所维护的基站标识信息和基站的相邻信息上报给网 管设备, 从而使得网管设备可以保存和维护一张全承载网连接的基站的基站标识信息和相 邻基站信息表。
由于网管设备具有一张全承载网连接的基站的基站标识信息和相邻基站信息表, 因此 承载网可据此建立相邻基站连接, 即 X2连接, 此后还可以根据基站相邻关系的变化进行相 邻基站连接的动态管理 (详见前面实施例, 在此不在赘述) , 从而实现相邻基站连接的动 态建立与维护, 实现提高网络建网的效率和降低运维成本的目的。
如图 4所示, 具体流程可以如下:
301、 承载节点检测到各自连接的基站的基站标识信息, 比如基站的 ID或 IP, 识别出 所连接的基站, 并维护基站连接表。
302、 承载节点分别根据步骤 301中的基站连接表与基站建立通信连接, 然后分别通过 建立的通信连接与基站进行信息交互, 以获取基站的相邻信息, 各个承载节点可以根据获 取到的基站的相邻信息维护一张基站邻居关系表。
303、 网管设备获取各个承载节点的基站标识信息和相邻信息, 建立相邻基站的连接, 具体的建立方式可在现有技术的基础上, 根据运营商的策略而定。
例如, 网管设备可以接收承载节点主动上报的基站标识信息和基站的相邻信息, 或者 也可以发送查询消息给承载节点, 然后接收承载节点发送的接入信息和基站的相邻信息, 网管设备在接收到基站标识信息和基站的相邻信息后, 便可获知承载网内的相邻基站的承 载连接需求, 即可在承载网内为相邻基站创建连接。
由上可知, 本实施例承载网中的承载节点可以获取基站的基站标识信息和基站的相邻 信息, 然后将获取到的基站标识信息和基站的相邻信息上报给网管设备, 由网管设备依据 该基站标识信息和基站的相邻信息来自动建立相邻基站的连接, 大大减少了现有技术中对 网管设备大量的配置与维护工作, 比如, 在基站停电、 基站搬迁与扩容等场景发生时, 就 可以无需花费大量的人力物力对配置数据进行重新配置以建立新的相邻基站的连接, 因 此, 采用本发明实施例所提供的方案, 可以提升了网络运维效率、 降低运营和维护的复杂 度和降低运营和维护的成本。
同时, 由于连接是网络自动创建的, 因此, 承载网可根据网络资源利用的情况, 预先 制定与网络资源相适应的策略, 然后根据该预置的策略来创建链路, 可以充分地提升网络 资源利用率。
进一步的, 由于是由网络自动创建连接, 因此在网络发生变更时, 可以避免现有技术 中由于需要人工进行静态配置所导致的配置数据调整不及时而造成的通信网络故障等问 题, 可以提升网络服务质量。
实施例四、
根据实施例一所描述的方法, 本实施例将举例作进一步详细说明。
在本实施例中, 将以由各个承载节点发起建立相邻基站的连接为例进行说明, 与实施 二不同的是, 在本实施例中, 承载网中的各个承载节点只需将获取到接入信息在承载网内 部进行传递和扩散, 而不需要将基站的相邻信息在承载网内部进行传递和扩散。 各个承载 节点分别根据自身所获取到的基站的相邻信息发起相邻基站的连接建立请求。 各个承载节 点都有各个基站的接入信息, 因此可以得到上述相邻基站的连接应当在哪些承载节点间建 立, 各个承载节点之需要分别根据自身所获取到的基站的相邻信息和承载网中的接入信息 就可以完成相邻基站的连接的建立。
可以在承载节点与基站间, 增加一个通信协议接口, 使得承载节点可以获知与其连接 的基站的基站标识信息, 比如基站的 ID或 IP地址等, 并在后续也可以通过该通信协议接口 获取基站的相邻信息; 其中, 基站标识信息具体的获取方式可根据不同的网络技术与连接 方式, 采用不同的方案, 当然, 在获取基站标识信息时也可以不通过该增加的通信协议接 口, 比如采用侦听或监控接入基站的 IP地址等方式来获取。
承载节点获取到基站标识信息后, 可以将获取到基站标识信息发送给承载网中的其他 承载节点, 并接收其他承载节点发送过来的基站标识信息, 根据自身获取到的基站标识信 息以及其他承载节点发送过来的基站标识信息保存和维护基站和各个承载节点的连接关 系, 从而得到一张全网的基站接入表, 根据自身获取到的基站标识信息获取基站的相邻信 息, 并保存该相邻信息, 比如可以保存并维护一张基站邻居关系表; 然后, 该承载节点便 可以根据自身所保存的全网的基站接入表和基站邻居关系表发起建立相邻基站的连接, 即 X2连接。 同理, 承载网中的其他承载节点也执行同样的操作, 这样, 便可以建立起全网的 相邻基站的连接。 具体实施方式与前面实施例类似, 在此不再赘述。
需说明的是, 为适应网络的动态变化, 还可以根据基站相邻关系的变化进行相邻基站 连接的动态管理 (详见前面实施例, 在此不在赘述) , 从而实现相邻基站连接的动态建立 与维护, 实现提高网络建网的效率和降低运维成本的目的。
由上可知, 本实施例承载网中的承载节点可以获取基站的接入信息和基站的相邻信 息, 并依据该获取到的接入信息和基站的相邻信息来自动建立相邻基站的连接, 大大减少 了现有技术中对网管设备大量的配置与维护工作, 比如, 在基站停电、 基站搬迁与扩容等 场景发生时, 就可以无需花费大量的人力物力对配置数据进行重新配置以建立新的相邻基 站的连接, 因此, 采用本发明实施例所提供的方案, 可以提升了网络运维效率、 降低运营 和维护的复杂度和降低运营和维护的成本。
同时, 由于连接是网络自动创建的, 因此, 承载网可根据网络资源利用的情况, 预先 制定与网络资源相适应的策略, 然后根据该预置的策略来创建链路, 可以充分地提升网络 资源利用率。
进一步的, 由于是由网络自动创建连接, 因此在网络发生变更时, 可以避免现有技术 中由于需要人工进行静态配置所导致的配置数据调整不及时而造成的通信网络故障等问 题, 可以提升网络服务质量。

建立单元 403, 还用于根据接入信息获取单元 401获取到的接入信息和相邻信息更新单 元 404更新的基站的相邻信息建立相邻基站的连接, 具体可以是根据保存和维护子单元 4014保存和维护的接入信息和信息交互子单元 4022 (此时, 信息交互子单元 4022中的基站 的相邻信息已由相邻信息更新单元 404更新) 中的基站的相邻信息建立相邻基站的连接。
其中, 建立单元 403, 具体用于主动上报接入信息获取单元 401获取到的接入信息和相 邻信息获取单元 402获取到的相邻信息给网管设备, 以便网管设备根据接收到的接入信息 和相邻信息建立相邻基站的连接; 或者, 在接收到网管设备的查询后, 发送接入信息获取 单元 401获取到的接入信息和相邻信息获取单元 402获取到的相邻信息给网管设备, 以便网 管设备根据接收到的接入信息和相邻信息建立相邻基站的连接; 或者,
