具体实施方式
为了解决现有技术中由于微基站接入网关不能提供正常服务时，影响移动 终端通讯服务质量的问题，本发明实施例提供一种接入网关选择的方法、设备 和系统。
如图 1所示， 本发明实施例提供的接入网关选择的方法， 包括： 步骤 101， 根据所在网络中微基站接入网关的服务能力信息， 选择目标微 基站接入网关。
所述步骤 101中，所述所在网络中微基站接入网关的服务能力信息为所在 网络中微基站接入网关的负载能力信息。
在本实施例中，所述微基站接入的原微基站接入网关不能给该微基站提供 正常的服务包括原微基站接入网关发生负载超载或需要对整个网络进行传输 优化或原微基站接入网关发生故障。在微基站接入的原微基站接入网关不能给 所述微基站提供正常的服务时，网络管理实体可以选择能够替代所述原微基站 接入网关的目标微基站接入网关。
步骤 102， 发送携带目标微基站接入网关标识信息的消息给所述微基站。 在本实施例中，使得微基站根据所述携带目标微基站接入网关标识信息的 消息， 接入到所述目标微基站接入网关标识信息对应的目标微基站接入网关， 实现微基站接入网关的选择或使得所述目标微基站接入网关为请求入网的终 端进行预附着操作。
本发明实施例提供的接入网关选择的方法，通过网络管理实体发送携带有 目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的微基 站，使得微基站选择到能够提供正常服务的目标微基站接入网关，解决了由于 微基站接入网关不能提供正常的服务， 影响用户设备通讯服务质量的问题。
如图 2所示， 本发明实施例提供的接入网关选择的方法， 包括： 步骤 201， 接收携带目标微基站接入网关标识信息的消息；
在本实施例中，所述携带目标微基站接入网关标识信息的消息由网络管理 实体， 如自组织网络（ Self-Organized Network, SON )服务器， 发送的。
所述的 SON服务器是一个逻辑上的网络管理功能实体， 可以单独部署， 也可以部署在接入网关上。 当部署在接入网关上时，所述携带目标微基站接入 网关标识信息的消息就是从微基站接入网关发送到微基站。
步骤 202， 根据所述消息中的目标微基站接入网关标识信息， 建立与所述 目标微基站接入网关之间的通信连接。 和 /或
步骤 203， 根据所述消息中的目标微基站接入网关标识信息， 所述目标微 基站接入网关为请求入网的终端进行预附着操作。
在本实施例中， 所述步骤 202， 如图 3所示， 包括： 步骤 2021， 根据所述 消息中的目标微基站接入网关标识信息，建立与所述目标微基站接入网关之间 的通讯接口； 步骤 2022， 通过所述通讯接口注册到所述目标微基站接入网关。
本发明实施例提供的接入网关选择的方法，通过网络管理实体发送携带有 目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的微基 站，使得微基站选择到能够提供正常服务的目标微基站接入网关，解决了由于 微基站接入网关不能提供正常的服务， 影响用户设备通讯服务质量的问题。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的技术方案， 下面通过具体的实施例，对本发明实施例提供的接入网关选择的方法进行详细 说明。
如图 4所示， 本发明又一实施例提供的接入网关选择的方法，应用于微基 站初始化过程完成后， 在向微基站接入网关注册失败， 需要选择接入网关时， 该方法实现的前提是微基站向原微基站接入网关进行注册请求。
本发明实施例是在微基站向原微基站接入网关进行注册请求时，由于所述 原微基站接入网关向该微基站返回了注册失败响应消息，所述注册失败响应消 息包含注册失败原因信息； 该微基站在接收到所述注册失败响应消息时，发送 选择接入网关请求消息给 SON服务器， 并在该消息中携带选择的原因信息， 这些原因信息可以是其接收到的注册失败的原因信息， 使得 SON服务器给该 微基站选择新的微基站接入网关， 即目标微基站接入网关， 其具体步骤如下所 述：
步骤 301， 微基站向原微基站接入网关发送注册请求消息。 这一步骤发生 在微机站初始化过程完成后， 或在微基站运营其间注销后再次发起注册时。
步骤 302， 所述原微基站接入网关返回注册失败响应消息给所述微基站。 在本实施例中，当所述微基站接入网关接入的负载已处于饱和状态或根据 运营策略不再接受微基站接入时，当所述微基站向所述原微基站接入网关发送 注册请求消息时，所述原微基站接入网关会给所述微基站返回一个注册失败响 应消息， 该注册失败响应消息中包含了注册失败原因信息。
步骤 303， 所述微基站接收所述注册失败响应消息。 该消息中包含注册失 败的原因， 如负载超载、 传输优化等。
步骤 304， 在所述微基站接收到所述注册失败响应消息时， 所述微基站向 SON服务器发送选择接入网关请求消息 （如 FeGW Re-selection Request )， 该 消息中包含选择接入网关原因信息和 /或原微基站接入网关标识信息， 其中选 择接入网关原因信息可以是注册失败原因信息、 注销原因信息等， 用于 SON 服务器在选择接入网关时作为参考依据。这里所说的原微基站接入网关标识信 息， 可以是原微基站接入网关的 IP ( Internet protocol, 因特网协议）地址或 MAC(Media Access Control, 介质访问控制)地址， 或其它可以在网络中能够标 识微基站接入网关身份或通讯地址的信息， 通过原微基站接入网关标识信息， 使得 SON服务器避免再次选择原接入网关。 另外， SON服务器也可以在微基 站初始化时就记录每个微基站所使用的接入网关。 所述的 SON服务器是一个 逻辑上的网络管理功能实体， 可以单独部署， 也可以部署在接入网关上。 当部 署在接入网关上时， 所述微基站向 SON服务器发送选择接入网关请求消息就 是从微基站发送到微基站接入网关。
步骤 305， 在 SON服务器接收到所述微基站发送的选择接入网关请求消 息时， 判断得到所述原微基站接入网关不能给微基站提供正常的服务， 并根据 消息中包含的选择接入网关原因信息， 获知微基站选择的原因，还可以根据原 微基站接入网关标识信息， 获知微基站原来使用的微基站接入网关。
步骤 306，在原微基站接入网关不能给微基站提供正常的服务时， SON服 务器选择能够替代所述原微基站接入网关的目标微基站接入网关。
在本实施例中， 所述 SON服务器选择能够替代所述原微基站接入网关的 目标微基站接入网关是通过以下步骤实现：当所述原微基站接入网关负载超载 时， SON服务器首先获得与其所在网络中各微基站接入网关相连的微基站的 负载信息，并根据所述与所在网络中微基站接入网关相连的微基站的负载信息 计算出所述所在网络中微基站接入网关的负载状况，然后根据所述负载状况选 择所述目标微基站接入网关。 需要说明的是， 在上述目标微基站接入网关选 择过程中， 结合需要选择微基站接入网关的微基站的位置信息， 以及所述微基 站发送的选择接入网关请求消息包含的选择接入网关原因信息，为该微基站选 择一个符合微基站需求的目标微基站接入网关，并获取该目标微基站接入网关 的标识信息。 值得说明的是所述微基站的位置信息为微基站的物理位置信息。
在本实施例中， 所述 SON服务器选择能够替代所述原微基站接入网关的 目标微基站接入网关， 包括： 获取与所在网络中微基站接入网关相连的微基站 的负载信息；根据所述与所在网络中微基站接入网关相连的微基站的负载信息 计算出所述所在网络中微基站接入网关的负载状况；根据所述负载状况选择所 述目标微基站接入网关。
步骤 307， SON服务器发送携带目标微基站接入网关标识信息的消息给所 述微基站， 即发送选择接入网关响应消息 （如 FeGW Re-selection Response )。 这里所说的目标微基站接入网关标识信息， 可以是目标微基站接入网关的 IP ( Internet protocol )地址或 MAC(Media Access Control, 介质访问控制)地址， 或其它可以在网络中能够标识微基站接入网关身份或通讯地址的信息。
步骤 308， 微基站接收携带目标微基站接入网关标识信息的消息， 即接收 选择接入网关响应消息。
步骤 309， 根据所述消息中的目标微基站接入网关标识信息， 微基站建立 与所述目标微基站接入网关之间的通讯接口，并通过所述通讯接口注册到所述 目标微基站接入网关。 对于 WiMAX微基站网络来说， 所说的通讯接口就是 R6-F接口。
步骤 310， 微基站拆除与所述原微基站接入网关之间的通讯接口。
本发明实施例使得微基站通过安全网关连接到目标微基站接入网关，通过 目标微基站接入网关为移动终端提供 WiMAX业务网络的接入服务。
本发明实施例方法可以根据实际需要对各个步骤顺序进行调整， 以及合 并。例如步骤 310可以在步骤 303之后执行， 即微基站收到原微基站接入网关 发送的注册失败响应消息之后，微基站和原微基站接入网关即可拆除两者之间 的通讯接口。当然步骤 310不一定是微基站收到注册失败响应消息之后立即发 起的，也可由微基站内部设置定时器， 定时到达时自动拆除与原微基站接入网 关之间的通讯接口。如果微基站在初始化时与多个微基站接入网关建立通讯接 口， 则步骤 309不一定要执行； 即如果微基站在初始化时与目标微基站接入网 关已建立通讯接口并注册， 则步骤 309可以不执行。
本发明实施例提供的接入网关选择的方法， 通过 SON服务器发送携带有 目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的微基 站，使得该微基站放弃所述原微基站接入网关而是与目标微基站网关连接， 实 现了微基站上电初始化正常工作之后到接入网关注册失败时可选择可接入的 目标微基站接入网关，解决了由于微基站接入网关不能提供正常的服务， 影响 用户设备通讯服务质量的问题。
进一步的，所述目标微基站接入网关与所述原微基站接入网关并不一定都 是通过同一安全网关与微基站进行连接的。
本发明又一实施例提供的接入网关选择的方法， 如图 5所示， 由 SON服 务器判断所述目标微基站网关连接的安全网关 （SeGW2 ) 与所述原微基站连 接的安全网关 （SeGWl )是不是同一个安全网关， 避免了所述目标微基站接 入网关与所述原微基站接入网关不是通过同一安全网关微基站与基站进行连 接，使得目标微基站接入网关无法与微基站通信的情况发生， 该方法的具体步 骤， 包括上述步骤 301-步骤 310， 在步骤 308之后还包括：
步骤 312a， 在所述目标微基站网关连接的安全网关与所述原微基站连接 的安全网关不是同一个安全网关时， SON服务器查找与所述目标微基站网关 连接的安全网关。
在本实施例中， SON服务器判断所述目标微基站网关与所述原微基站网 关是否与同一个安全网关连接，可以通过预先保存的安全网关与微基站接入网 关之间的连接关系表进行判断， 该关系表可以预先保存于 SON服务器或引导 服务器中。 并且， 在 SON服务器查找到与所述目标微基站网关连接的安全网 关后，可以通过引导服务器来获取与所述目标微基站接入网关连接的安全网关 的 IP地址， 并将该 IP地址作为该安全网关的标识信息。
值得说明的是， 所述安全网关的标识信息不仅限于与 IP地址来表示， 且
IP地址的获取途径也不仅限于通过引导服务器来获取。 这里所说的安全网关 标识信息，可以是安全网关的 IP ( Internet protocol )地址或 MAC(Media Access Control, 介质访问控制）地址， 或其它可以在网络中能够标识安全网关身份或 通讯地址的信息。
步骤 313a， SON服务器发送携带与所述目标微基站网关连接的安全网关 的标识信息的消息给所述微基站。这里所说的安全网关标识信息， 可以是安全 网关的 IP ( Internet protocol )地址或 MAC(Media Access Control, 介质访问控 制)地址， 或其它可以在网络中能够标识安全网关身份或通讯地址的信息。
步骤 314a， 微基站接收携带与所述目标微基站网关连接的安全网关的标 识信息的消息。
步骤 315a， 微基站根据所述携带与所述目标微基站网关连接的安全网关 的标识信息的消息， 建立与所述安全网关之间的通信连接。这里所说的通讯连 接通常是指在微基站与安全网关之间的安全隧道（ IP Sec tunnel )， 在这一步的 具体实施过程中， 在微基站与安全网关之间建立安全隧道后， 可根据具体的认 证策略，该过程可能触发微基站通过所述目标微基站网关连接的安全网关到微 基站认证服务器的认证过程， 具体的认证过程可参考已有的规范内容。
步骤 316a， 微基站返回响应消息给 SON服务器， 以确认接收到安全网关 标识信息， 并指示微基站与安全网关之间的通信连接建立的结果。本发明不对 该消息的发送时刻作限制， 但如果在步骤 315a前发送， 则该消息不能够指示 微基站与安全网关之间的通信连接的建立的结果。
步骤 316a之后执行步骤 309和 310， 以及 317。
步骤 317， 微基站拆除与安全网关之间的通讯连接， 该安全网关是与所述 原微基站接入网关相连的安全网关。这里所说的通讯连接通常是指在微基站与 安全网关之间的安全隧道（IP Sec tunnel ), 在这一步的具体实施过程中， 微基 站与安全网关拆除其间的安全隧道，根据具体的认证策略， 该过程可能触发微 基站通过所述原微基站网关连接的安全网关到微基站认证服务器的撤销认证 过程， 具体的认证过程可参考已有的规范内容。
在本实施例中，所述建立与所述安全网关之间的通信连接通过以下步骤实 现： 微基站与所述目标微基站网关连接的安全网关建立安全隧道， 并通过安全 网关中的认证器与微基站认证服务器完成认证过程。
本发明实施例方法可以根据实际需要对各个步骤顺序进行调整， 以及合 并。 其中步骤 312a可以与步骤 305、 306合并， 即选择目标微基站接入网关时 同时查找与所述目标微基站网关连接的安全网关， 这种情况下， 目标微基站接 入网关连接的安全网关的标识信息可以携带在步骤 307、 308的选择接入网关 响应消息中发送给微基站， 步骤 313a和 314a可以不执行了。 如果微基站在初 始化时已与目标微基站连接的安全网关建立通信连接，与目标微基站建立通信 接口并注册， 则步骤 315a和 309可以不执行。 步骤 310可以在步骤 303之后 执行， 即微基站收到原微基站接入网关发送的注册失败响应消息之后， 微基站 和原微基站接入网关即可拆除两者之间的通讯接口。当然步骤 310不一定是微 基站收到注册失败响应消息之后立即发起的， 也可由微基站内部设置定时器， 定时到达时自动拆除与原微基站接入网关之间的通讯接口。
本发明实施例提供的接入网关选择的方法， 通过 SON服务器发送携带有 目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的微基 站，使得该微基站放弃所述原微基站接入网关而是与目标微基站网关连接， 实 现了微基站上电初始化正常工作之后到接入网关注册失败时可选择可接入的 目标微基站接入网关，解决了由于微基站接入网关不能提供正常的服务， 影响 用户设备通讯服务质量的问题。
本发明又一实施例提供的接入网关选择的方法，如图 6所示， 由微基站判 断所述目标微基站网关连接的安全网关 （SeGW2 )与所述原微基站连接的安 全网关 （SeGWl )是不是同一个安全网关， 避免了所述目标微基站接入网关 与所述原微基站接入网关不是通过同一安全网关微基站与基站进行连接，使得 目标微基站接入网关无法与微基站通信的情况发生， 该方法的具体步骤， 包括 上述步骤 301-步骤 310， 步骤 308之后还包括：
步骤 312b， 在目标微基站接入网关连接的安全网关与所述原微基站接入 网关连接的安全网关不是同一个安全网关时，获取与所述目标微基站接入网关 连接的安全网关的标识信息。
在本实施例中，微基站判断所述目标微基站网关与所述原微基站网关是否 与同一个安全网关连接，可以通过预先保存的安全网关与微基站接入网关之间 的连接关系表进行判断， 该关系表可以预先保存于 SON服务器或引导服务器 中。 并且，微基站可以获取引导服务器来获取的与所述目标微基站接入网关连 接的安全网关的 IP地址作为该安全网关的标识信息。 值得说明的是， 所述安全网关的标识信息不仅限于使用 IP地址、 MAC地 址来表示， 且 IP地址的获取途径也不仅限于通过引导服务器来获取。
步骤 313b， 根据所述安全网关的标识信息， 建立与该安全网关的通信连 接。 在本实施例中， 所述步骤 313b与所述步骤 315a的实现方法相同， 此处不 再赘述。
步骤 313b之后执行 309、 310、 317。
步骤 317， 微基站拆除与安全网关之间的通讯接口， 该安全网关是与所述 原微基站接入网关相连的安全网关。
本发明实施例方法可以根据实际需要对各个步骤顺序进行调整， 以及合 并。 其中如果微基站在初始化时已与目标微基站连接的安全网关建立通信连 接， 与目标微基站建立通信接口并注册， 则步骤 313b和 309可以不执行。 步 骤 310可以在步骤 303之后执行，即微基站收到原微基站接入网关发送的注册 失败响应消息之后， 微基站和原微基站接入网关即可拆除两者之间的通讯接 口。 当然步骤 310不一定是微基站收到注册失败响应消息之后立即发起的，也 可由微基站内部设置定时器，定时到达时自动拆除与原微基站接入网关之间的 通讯接口。
本发明实施例提供的接入网关选择的方法，通过自组织网络服务器发送携 带有目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的 微基站， 使得该微基站放弃所述原微基站接入网关而是与目标微基站网关连 接，实现了微基站上电初始化正常工作之后到接入网关注册失败时可选择可接 入的目标微基站接入网关， 解决了由于微基站接入网关不能提供正常的服务， 影响用户设备通讯服务质量的问题。 如图 7所示， 本发明再一实施例， 应用于网络运行过程中， 该方法实现的 前提是微基站通过安全网关连接到微基站接入网关，通过微基站接入网关为移 动终端提供到 WiMAX业务网络的接入服务。
本发明实施例由原微基站接入网关主动发现自身负载超载或因为传输优 化或将要关闭等原因，从与该原微基站接入网关相连接的微基站中选择一个或 几个微基站， 向其发送注销请求消息， 在该消息中携带注销的原因信息， 该微 基站在接收到所述注销请求消息，发送选择接入网关请求消息给 SON服务器， 并在该消息中携带选择的原因信息，这些原因信息可以是其接收到的注销请求 消息中携带注销的原因信息， 使得 SON服务器给该微基站重新分配新的微基 站接入网关， 即目标微基站接入网关， 其具体步骤如下所述：
步骤 401， 原微基站接入网关发现自身情况异常。
在本实施例中， 所述自身情况异常包括所述原微基站接入网关负载超载、 所述原微基站接入网关需要进行传输优化或所述原微基站将要关闭等。
步骤 402， 在原微基站接入网关发现自身情况异常时， 所述原微基站接入 网关向微基站发送注销请求消息。
在本实施例中，所述注销请求消息中包括负载超载信息或因为传输优化或 将要关闭等原因信息；所述微基站是与所述原微基站接入网关连接的多个微基 站中的一个或多个。选择与所述原微基站接入网关连接的多个微基站中的一个 或多个， 可以根据所述多个微基站连接移动终端的负载情况进行选择， 当然在 进行选择需要改变微基站接入网关的微基站，其考虑的因素并不仅限于上述的 多个微基站连接移动终端的负载情况， 此处不——赘述。
步骤 403， 微基站接收原微基站接入网关发送的注销请求消息。 步骤 404， 微基站向 SON服务器发送选择接入网关请求消息。 微基站在该消息中包含选择接入网关原因信息和 /或原微基站接入网关标 识信息， 其中选择接入网关原因信息可以是注册失败原因信息、 注销原因信息 等。
步骤 404之后执行以及上述实施例所述的步骤 305-步骤 310。
通过所述步骤 401-步骤 404以及步骤 305-步骤 310使得微基站通过安全 网关连接到目标微基站接入网关， 通过目标微基站接入网关为移动终端提供 WiMAX业务网络的接入服务。
在本实施例中， 所述步骤 309， 微基站建立与所述目标微基站接入网关之 间的通讯接口， 并通过所述通讯接口注册到所述目标微基站接入网关之后，还 包括步骤 311a， 所述微基站返回注销请求响应消息给原微基站接入网关， 说 明微基站对注销请求响应的结果。
本发明实施例方法可以根据实际需要对各个步骤顺序进行调整， 以及合 并。如果微基站在初始化时已与目标微基站连接的安全网关建立通信连接， 与 目标微基站建立通信接口并注册， 则步骤 309可以不执行。本发明实施例提供 的接入网关选择的方法， 通过 SON服务器发送携带有目标微基站接入网关标 识信息的消息给与所述原微基站接入网关连接的微基站，使得该微基站放弃所 述原微基站接入网关而是与目标微基站网关连接，实现了微基站上电初始化正 常工作之后在与该微基站连接的原微基站接入网关发生负载超载等情况时选 择可接入的目标微基站接入网关，解决了由于微基站接入网关不能提供正常的 服务， 影响用户设备通讯服务质量的问题。

进一步的，所述目标微基站接入网关与所述原微基站接入网关并不一定都 是通过同一安全网关与微基站进行连接的。
本发明另一实施例提供的接入网关选择的方法， 如图 9所示， 由 SON服 务器判断所述目标微基站网关连接的安全网关与所述原微基站连接的安全网 关是不是同一个安全网关，避免了所述目标微基站接入网关与所述原微基站接 入网关不是通过同一安全网关微基站与基站进行连接，使得目标微基站接入网 关无法与微基站通信的情况发生， 该方法的具体步骤包括上述步骤 501-506， 步骤 312 -步骤316&， 步骤 507-步骤 509， 还有步骤 317， 此处不再赘述。

本发明实施例提供的接入网关选择的方法， 通过 SON服务器发送携带有 目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的微基 站，使得该微基站放弃所述原微基站接入网关而是与目标微基站网关连接， 实 现了微基站上电初始化正常工作之后在与该微基站连接的原微基站接入网关 不能提供正常的服务时选择可接入的目标微基站接入网关，解决了由于微基站 接不能提供正常的服务， 影响用户设备通讯服务质量的问题。
本发明另一实施例提供的接入网关选择的方法， 如图 10所示， 由微基站 判断所述目标微基站网关连接的安全网关与所述原微基站连接的安全网关是 不是同一个安全网关，避免了所述目标微基站接入网关与所述原微基站接入网 关不是通过同一安全网关微基站与基站进行连接，使得目标微基站接入网关无 法与微基站通信的情况发生， 该方法的具体步骤包括上述步骤 501-步骤 506， 还包括上述的步骤 312b-步骤 313b， 步骤 507-509和步骤 317， 此处不再赘述。
本发明实施例方法可以根据实际需要对各个步骤顺序进行调整， 以及合 并。 本发明实施例提供的接入网关选择的方法， 通过 SON服务器发送携带有 目标微基站接入网关标识信息的消息给与所述原微基站接入网关连接的微基 站，使得该微基站放弃所述原微基站接入网关而是与目标微基站网关连接， 实 现了微基站上电初始化正常工作之后在与该微基站连接的原微基站接入网关 不能提供正常的服务时选择可接入的目标微基站接入网关，解决了由于微基站 接不能提供正常的服务， 影响用户设备通讯服务质量的问题。
为了实现微基站接入网关的负载均衡，除可以利用上述实施例提供的技术 方案， 由微基站根据微基站接入网关的服务能力情况，对微基站接入到网络所 使用的微基站接入网关进行选择外，还可以在终端入网时，通过微基站根据微 基站接入网关的服务能力为终端选择合适的微基站接入网关的方法，实现终端 在不同微基站接入网关上的分配优化， 从而实现微基站接入网关的负载均衡。 如图 11所示， 本发明又一个实施例提供的微基站接入网关选择方法， 包括： 步骤 601， 微基站在初始化过程中获得 SON服务器指定的多个可用的接 入网关， 微基站与这些接入网关中的一个或多个建立 R6-F通讯接口， 并进行 注册。
步骤 602， 终端在需要接入到微基站网络时， 向微基站发送包含入网请求 指示信息的 RNG_REQ (测距请求）消息， 微基站接收终端发送的入网请求消 息， 并向终端发送 RNG_RSP (测距响应） 消息。
步骤 603， 在接收到测距响应消息后， 终端向微基站发送能力协商请求消 息。
步骤 604， 在接收到终端向微基站发送的能力协商请求消息后， 微基站针 对请求入网的终端向网络中的 SON服务器， 发送接入网关选择请求消息， 以 请求分配一个接入网关。 该消息中可能携带该微基站可用的接入网关信息，供 SON选择接入网关时参考。 该消息中还可以包含选择接入网关的原因信息， 本实施例中所说的选择接入网关的原因信息可能是， 终端初始入网、终端切换 过程中到目标基站的入网、终端到原接入网关预附着失败等原因信息中的一种 或几种。
可选地， 当接收到终端向微基站发送的能力协商请求消息后，微基站也可 以直接选择一个可用的微基站接入网关 （缺省的或随机的）发起预附着请求， 在接收到该微基站接入网关发送的预附着失败消息后再向网络中的 SON服务 器发送接入网关选择请求消息， 以请求分配一个接入网关， 并在消息中携带该 微基站可用的接入网关信息和 /或预附着失败的接入网关标识信息，供 SON在 选择时参考，其具体实现方式与上述实施例中微基站接收到原微基站接入网关 发生的注销请求消息或注册失败响应消息后的步骤相同， 此处不再赘述。

(如接入网关的 IP地址或 MAC地址等 )发送到微基站。
步骤 607， 微基站针对请求入网的终端， 向 SON服务器在接入网关选择 响应消息中指定的微基站接入网关（即目标微基站接入网关）发送预附着请求 消息（如 Pre-attachment request )。 需要说明的是， 如果微基站在初始化过程中 没有与所指定的微基站接入网关建立 R6-F通讯接口， 并进行注册， 那么在向 所指定的微基站接入网关发送预附着请求消息 （ Pre-attachment request )前， 需要事先与所指定的微基站接入网关建立 R6-F通讯接口， 并进行注册。
步骤 608， 微基站接入网关向微基站发送预附着响应消息 （如 Pre-attachment response )。
步骤 609， 微基站向终端发送能力协商响应消息。
