- the fault sending module sends the information of the MME corresponding to the faulty S1 link to the neighboring base station by using the base station configuration update message.
- the base station configuration update message includes one or all of the following information:
- Deleting the information of the MME including the information of the MME corresponding to the faulty S1 link in the S1 link between the base station and all the MMEs connected thereto;
- the information of the MME is updated, and the information of the MME corresponding to the normal S1 link is restored in the S1 link between the base station and all the MMEs connected thereto.

- the base station may further include:
- a request receiving module 903, configured to receive a handover request message sent by the neighboring base station
- the response sending module 904 is configured to send a response message of the handover request message to the neighboring base station, where the response message includes a handover failure cause, and the handover failure cause includes information of the S1 link failure.
- the response message includes a handover preparation failure response message.
- the present invention provides another base station.
- the first base station may specifically include:
- the third receiving module 1101 is configured to receive information about an MME sent by a neighboring base station, where an S1 link between the MME and the neighboring base station is faulty;
- the acknowledgment module 1102 is configured to send an acknowledgment message to the neighboring base station when the information of the MME is correctly received.
- the base station when a certain base station receives the information of the MME corresponding to the faulty S1 link fed back by the neighboring base station, the base station can know the S1 link fault corresponding to a certain MME of the neighboring base station. Therefore, when there is a user equipment in the base station that needs to be handed over to the neighboring base station, it may be known in advance which S1 link is faulty, thereby avoiding initiating the X2 handover related to the faulty S1 link to the neighboring base station again, thereby avoiding recurrence. The scenario where the X2 switch fails, and the LTE switching efficiency is improved.
- the third receiving module receives the information of the MME by using a base station configuration update message sent by the neighboring base station.

为了应对无线宽带技术的挑战, 保持第三代合作伙伴计划 (The 3rd generation partnership project, 3 GPP) 网络的领先优势, 3GPP制定了移动通信网络的长期演进
(long term evolution, LTE) 计划, 在此演进计划的指导下, 定义了新的移动通信网 络架构, 即, 长期演进 /***架构演进 (Long Term Evolution /System Architecture Evolution, LTE/SAE) 网络***的架构。
在 LTE/SAE网络中, 切换可以划分为基于 X2的切换和基于 S1的切换。 当切换 的源和目标基站(例如演进型节点 B (evolved Node B, e B),又称之为演进型基站)) 之间建立了 X2信令面连接, 并且源 eNB和目标 eNB 属于同一个移动性管理实体
(Mobility Management Entity, MME) 资源池时, 即可以发起基于 X2的切换, 否则 发起基于 S1的切换。
目前, 在 X2的切换过程中, 如果 X2切换失败, 源基站会开启保护定时器, 在 该定时器超时之前禁止向目标基站发起 X2切换。 然而, 在定时器超时以后仍会再次 触发向目标基站的切换, 可能导致新的切换失败。

在基于 X2的切换过程中, 源 eNodeB和目标 eNodeB之间的信令面连接通过 X2 链接的建立流程来完成; 源 eNodeB和目标 eNodeB是否属于同一个 MME资源池, 通过 X2的配置更新流程来完成。
在 LTE切换中, 对于基于 X2 的切换, 存在如下场景: 源基站和目标基站所在 MME资源池中的某一个 MME出现异常, 该 MME与源基站之间的 S1链路正常, 该 MME与目标基站之间的 S1链路发生故障,当源基站在 X2切换请求中携带了该 MME 标识时, 目标基站判断出其与该 MME的 S1链路故障之后, 会向源基站返回 X2切 换失败消息 HANDOVER PREPARATION FAILURE, 切换失败消息中的失败原因为 " Unspecified "。 目前, 3GPP协议中无法实现通知源基站上述 X2切换失败场景下 的切换失败原因,源基站也无法从配置更新流程中获知目标基站与某一个 MME的链 路状态, 由于源基站无法获知目标基站相关的 S1链路异常, 会继续在该 X2链路上 发起与异常 S1链路相关的切换, 从而导致切换成功率降低。
为了提高上述应用场景下的 LTE切换效率, 本发明公开了相应的通信方法和设
备。
首先介绍本发明提供的通信方法。 为了便于描述, 将源基站假设为第一基站, 将 目标基站假设为第二基站。 如图 1所示, 为本发明提供的一种通信方法实施例, 该方 法可以包括以下执行步骤:
步骤 101、 第一基站获取作为目标基站的第二基站的 S1链路故障的相关信息; 步骤 102、 所述第一基站根据所述 S1链路故障的相关信息, 确定切换类型或者 重新选择目标基站。
本方面实施例中, 对于基于 X2的切换, 如果作为源基站的第一基站和作为目标 基站的第二基站所在 MME资源池中的某一个 MME出现异常, 该 MME与第一基站 之间的 S1链路正常,而与第二基站之间的 S1链路发生故障时,通过向第一基站反馈 该 MME与第二基站之间的 S1链路故障信息,使得第一基站可以及时获取故障信息, 及时确定切换类型或者重新选择目标基站, 避免向第二基站再次发起与故障 S1链路 相关的 X2切换, 从而避免出现重复发生 X2切换失败的场景, 实现 LTE切换效率的 提高。
具体实施过程中, 所述 S1链路故障的相关信息可以包括切换失败原因, 其中, 所述切换失败原因包括 S1链路故障的信息,即通过该切换失败原因携带 S1链路故障 的信息, 该实现方式下, 上述步骤 101的具体实施方式如图 2所示:
步骤 201、 所述第一基站向所述第二基站发送切换请求消息 HANDOVER REQUEST;
步骤 202、 所述第一基站接收所述第二基站对所述切换请求消息的响应消息, 所 述响应消息中包括所述切换失败原因,所述切换失败原因包括 S1链路故障的信息 S1 PathError o 具体地, 所述响应消息可以为切换准备失败响应消息 HANDOVER PREPARATION FAILURE。
该实现方式下, 当所述第二基站接收到所述第一基站发送的 X2 切换请求 HANDOVER REQUEST之后, 如果发现与所述切换请求中携带的 MME之间的 S1 链路发生故障, 则向所述第二基站反馈切换失败消息 HANDOVER PREPARATION FAILURE, 并在切换失败消息 HANDOVER PREPARATION FAILURE中携带上述切 换失败原因信息 SI PathError. 所述第一基站根据接收到的切换失败原因信息, 获知 MME与所述第二基站之间 S1链路的故障状态, 不再向第二基站再次发起与故障 S1 链路相关的 X2切换, 从而避免出现重复发生 X2切换失败的场景。
所述源基站可以通过选择其它的候选目标基站或者通过基于 S1的切换, 继续实
现 LTE切换。
该实现方式下, 通过修改现有的 3GPP协议, 在第二基站向第一基站反馈的切换 失败消息 HANDOVER PREPARATION FAILURE中携带实际的切换失败原因, 使得 源基站可以根据实际的切换失败原因, 重新进行有效的 X2切换。
除此之外, 还可以通过设置第三方网元, 通过该第三方网元监测所述 MME分别 与第一基站和第二基站之间的 S1链路连接状态。 当所述第三方网元监测到所述第二 基站与所述切换请求中携带的 MME之间的 S1链路发生故障, 则向所述第二基站反 馈切换失败原因信息。所述第一基站根据接收到的切换失败原因信息, 获知 MME与 所述第二基站之间 S1链路的故障状态,不再向第二基站再次发起与故障 S1链路相关 的 X2切换, 从而避免出现重复发生 X2切换失败的场景。 具体实施时, 第三方网元 可以是基站的操作维护网元。
需要说明的是,所述 S1链路故障的相关信息可以包括故障 S1链路对应 MME的 信息, 并且, 另一种实现方式中, 所述第一基站获取第二基站的 S1链路故障的相关 信息包括:
所述第一基站接收所述第二基站发送的基站配置更新消息 eNB
CONFIGURATION UPDATE, 所述基站配置更新消息包括所述故障 S1 链路对应的 MME的信息, 且所述基站配置更新消息由所述第二基站监测到所述 S1链路故障时 发送给所述第一基站。
