应当理解的是, 以上的一般描述和后文的细节描述仅是示例性的, 并 不能限制本公开。
附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对 实施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员 来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附 图。

图 12是本发明实施例六中用于 UE的设备的示意图。
通过上述附图, 已示出本发明明确的实施例, 后文中将有更详细的描
具体实施方式 下面将结合本发明实施例中的附图 ,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 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作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
为了全面理解本发明,在以下详细描述中提到了众多具体的细节,但是本 领域技术人员应该理解, 本发明可以无需这些具体细节而实现。在其他实施例 中, 不详细描述公知的方法、 过程、 组件和电路, 以免不必要地导致实施例模 糊。
在现有技术中, 基站通常通过广播 SIB ( System Information Block ) 消 息来告知 UE 本小区所存在的运营商网络。 但是, 发明人在实现本发明的 过程中发现, 在多个运营商于某基站下共享网络的情形下, 当某个运营商 的网络出现了 S1链路故障后, 现有技术至多能通知存在运营商故障, 但却 无法进一步告知 UE具体是哪个或哪些运营商出现了故障,所以导致 UE无 法识别出故障运营商, 一旦 UE 想进行选择或重选择时, 其目标运营商恰 好就是该故障运营商, 那么则会出现 UE不断接入又释放的不正常现象。 实施例一
图 2为本发明实施例一方法的示例性流程图。 为了解决上述问题, 本 实施例提供了一种运营商共享网络中的故障处理方法, 用于第一基站, 在 所述第一基站下多个运营商共享网络, 所述方法包括:
S201、 获取故障运营商的标识, 所述故障运营商为所述第一基站下发 生了网络故障的运营商;
S202、 通过指定消息, 将所述故障运营商的标识通知所述第一基站下 的 UE, 以使所述第一基站下的 UE不再接入所述故障运营商在所述第一基 站下的网络; 其中, 所述指定消息中包含所述故障运营商的标识。
在本实施例中优选的, 所述指定消息可以为 SIB消息, 所述 SIB消息 的小区禁止 cellBarred字段中包含故障运营商列表,所述故障运营商列表中 包含所述故障运营商的标识。
上述方式相当于对 SIB 消息的 cellBarred字段进行了扩展。 在本发明 其他某些实施例中, 也可以利用其他的系统消息承载故障运营商的标识, 例如 paging消息中的 systeminfomodification。此夕卜还可以构建专门的消息, 定义新的消息格式, 以携带故障运营商的标识。 对于所述指定消息的具体 形式本发明并不进行限制, 可以在此处使用的这些消息都没有背离本发明 的精神和保护范围。
以上是站在第一基站侧的角度所进行的描述, 相对应的, 若在 UE侧, 则可以包括:
接收所述第一基站的指定消息, 所述指定消息中包含故障运营商的标 识, 所述故障运营商为所述第一基站下发生了网络故障的运营商;
根据所述故障运营商的标识, 停止发送接入所述故障运营商在所述第 一基站下的网络的请求。
此外, 在本实施例或本发明其他某些实施例中, 对于第一基站, 所述 方法还可以包括:
在获取故障运营商的标识即步骤 S201之前:
对所述第一基站下各运营商的网络到核心网的链路进行心跳检测( heat beat ), 以获知是否有运营商发生了网络故障。 在心跳检测中, 互联的双方 中的一方每隔固定时间向另一方发送一个很小的数据包(即心跳信号), 另 一方根据需要确定在收到数据包之后是否进行回复。 心跳检测的作用是为 了确认一个事实: 互联的双方在没有通讯的情况下是否都还在线, 或者说 存在于双方之间的通讯链路是否已经断开。
在基站下存在多个运营商共享网络的场景中, 当某个或某些运营商的 网络出现了故障 (如 S1 链路故障) 时, 本实施例可以通过指定消息 (如 SIB消息 ) 将故障运营商的标识通知给基站下的 UE, 使得 UE可以正确区 分出哪些运营商发生了网络故障, 从而避免发生 UE仍试图接入故障运营 商的网络等不正常现象。 实施例二
图 3为本发明实施例二方法的信令示意图。 本实施例基于实施例一, 是对实施例一所作的进一步细化。
在现有技术中, 基站广播的 SIB消息的一些字段可参见下表 1所示, 其中 cellBarred (小区禁止)字段用于指示当前小区是否被禁止接入。 若小 区的运营商出现故障, 则 UE即可根据 cellBarred字段不再进行接入。

plmn-ldentityList
List of PLMN identities. The first listed PLMN-identity is the primary PLMN. 然而, 发明人在实现本发明的过程中发现, 以上方式对于第一基站下 只有一个运营商是适用的, 因为此时由该运营商故障即可推出小区无法接 入, 但是, 当第一基站下有多个运营商时, 该方式则存在局限, 因为此时 一个运营商故障并不代表其他运营商也故障,故此时 cellBarred字段的指示 是模糊的, 导致 UE无法识别出其中的故障运营商, 进而也就无法釆取正 确的应对措施。
为此, 本实施例将 SIB 消息中的 cellBarred字段进行了扩展, 增加了 故障运营商列表(即表 2 中的 CellBarredPlmnList ), 该故障运营商列表可 用于列出故障运营商的标识, 也即指示出具体是哪个或哪些运营商出现了 故障。 也可以说, 本实施例将针对所有运营商网络 (PLMN ) 的通用的 cellBarred 转变为为针对每个单独 PLMN 的 cellBarred 。 UE 获知 CellBarredPlmnList后,便可以选择不再接入第一基站下该列表中的运营商, 而是选择第一基站下的其他运营商进行接入, 或选择其他基站进行接入, 等等。 表 2

具体的, 本实施例中可以包括如下步骤:
在第一基站侧:
5301、 第一基站通过心跳检测发现有运营商的网络出现了 S1 链路故 障。
5302、 构建带有故障运营商列表的 SIB消息。
5303、 将该 SIB消息广播给 UE。
在 UE侧:
5304、 UE收到该 SIB消息后, 取出其中的故障运营商列表。
5305、 UE应对运营商故障。 例如停止接入第一基站下该列表中的运营 商, 或选择第一基站下该列表外的其他运营商进行接入, 或选择其他基站 进行接入, 等等。
当然, 以上仅仅是一个示例, 在本发明其他某些实施例中, 还可以通 过其他方式对 SIB信息进行扩展, 或对其他系统消息进行扩展, 或定义新 的消息, 以携带故障运营商的标识。 对此本发明实施例不进行限制, 可以 在此处使用的这些方式都没有背离本发明的精神和保护范围。
在基站下存在多个运营商共享网络的场景中, 当某个或某些运营商的 网络出现了故障 (如 S1 链路故障) 时, 本实施例可以通过指定消息 (如 SIB消息 ) 将故障运营商的标识通知给基站下的 UE, 使得 UE可以正确区 分出哪些运营商发生了网络故障, 从而避免发生 UE仍试图接入故障运营 商的网络等不正常现象。 实施例三
本实施例基于上述实施例,是对上述实施例所做的进一步拓展和完善。 在上述实施例中, 第一基站通过扩展 SIB消息可以告知其小区内的 UE哪 些运营商出现了链路故障, 从而避免了 UE 的接入错误, 解决了运营商共 享网络中出现故障时的基本问题。 在本实施例中, 故障基站(即第一基站) 还可以进一步将运营商故障信息通知相邻基站(即第二基站), 以便相邻基 站做出相应的反应, 从而使得故障处理机制更加完善。
具体的, 在本实施例中, 对于第一基站, 所述方法还可以包括: 在获取故障运营商的标识之后:
将所述故障运营商的标识通知给与所述第一基站相邻的第二基站, 以 使所述第二基站禁止所述第二基站下的 UE切换至所述故障运营商在所述 第一基站下的网络。
以上是站在第一基站侧进行描述, 若站在第二基站侧, 则可以包括: 获取第一基站下的故障运营商的标识, 其中所述第一基站为所述第二 基站的相邻基站, 所述故障运营商为所述第一基站下发生了网络故障的运 营商;
根据所述故障运营商的标识, 禁止所述第二基站下的 UE切换至所述 故障运营商在所述第一基站下的网络。
具体实施时, 第一基站可以通过多种方式将故障运营商的标识通知给 第二基站, 下面给出一些示例:
( 1 )在第一种实现方式中, 第一基站将所述故障运营商的标识通知给 与所述第一基站相邻的第二基站, 具体可以包括:
通过向所述第二基站发送 X2配置更新消息,将所述故障运营商的标识 通知给所述第二基站,其中所述 X2配置更新消息中携带所述故障运营商的 标识。
以上是站在第一基站侧进行描述, 若站在第二基站侧, 则为: 所述获取第一基站下的故障运营商的标识, 包括:
通过接收所述第一基站发送的 X2配置更新消息,获取第一基站下的故 障运营商的标识, 其中所述 X2 配置更新消息中携带所述故障运营商的标 识。
图 4是本发明实施例三第一种实现方式的信令示意图, 可以包含如下 步骤:
在第一基站侧:
S401、 第一基站通过心跳检测发现有运营商的网络出现了 S1 链路断 链。
S402、向相邻的第二基站发送 eNB configuration Update消息,即 X2 配 置更新, 该消息中携带第一基站故障运营商的标识。
在第二基站侧:
S403、 第二基站进行应答, 即发送 eNB configuration Update Acknowledge。
S404、 第二基站根据获取到的第一基站故障运营商的标识, 禁止本小 区内的 UE切换到第一基站下出故障的运营商的网络。 具体的, 可以在第 二基站的邻区列表( NCL , Neighbour Cell List )中增加 Barred PLMN字段, 以指示该第二基站的每个相邻小区中分别有哪些运营商的网络出现了故 障。
容易理解的是,上述 S403和 S404两步骤之间的先后顺序可以不固定。
( 2 )在第二种实现方式中, 第一基站将所述故障运营商的标识通知给 与所述第一基站相邻的第二基站, 包括:
向 0SS告警,以使所述 0SS通知所述第二基站所述故障运营商在所述 第一基站下的网络出现故障。 以上是站在第一基站侧进行描述, 若站在第二基站侧, 则为: 所述获取第一基站下的故障运营商的标识, 包括:
通过接收 OSS通知, 获取第一基站下的故障运营商的标识。
图 5是本发明实施例三第二种实现方式的信令示意图, 可以包含如下 步骤:
S501、第一基站通过心跳检测发现有运营商的网络( PLMN1 )到 MME 的 S1链路出现断链。
S502、 第一基站通过 itf-N ( interface Northbound, 北向接口) 向 0SS 发出断链告警信息 ( broken alarm ), 该告警信息中携带 PLMN1的标识。
S503、 OSS通知第二基站, 第一基站的 PLMN1 出现断链。
S504、 第二基站禁止本小区内的 UE切换到第一基站下的 PLMN1。 在本实施例中, 故障基站 (即第一基站) 进一步将运营商故障信息通 知相邻基站 (即第二基站), 以便相邻基站获知故障基站中是哪些 PLMN 出现了故障, 以做出相应的反应, 从而使得故障处理机制更加完善。 实施例四
本实施例基于上述实施例,是对上述实施例所做的进一步拓展和完善。 当第一基站出现了运营商链路故障后, 若及时通知了相邻基站, 则相邻基 站可以主动阻止其下的 UE切换至第一基站下的该故障运营商 (参见实施 例三)。 但若相邻基站未及时获知, 则可能仍会有 UE欲从相邻基站切换至 第一基站下的该故障运营商, 对此, 在本实施例中第一基站可以釆取主动 拒绝的方式, 拒绝相邻基站下的 UE所欲进行的切换。 即, 在本实施例中, 对于第一基站, 所述方法还可以包括:
在获取故障运营商的标识之后:
当接收到与所述第一基站相邻的第二基站发来的 UE 的切换请求时, 拒绝所述 UE的切换请求, 其中, 所述 UE的切换请求为所述第二基站下的 UE欲切换至所述故障运营商在所述第一基站下的网络的请求。
图 6为本发明实施例四方法的信令示意图, 可以包括如下步骤:
S601、 第一基站通过心跳检测发现有运营商的网络(PLMN1 ) 出现了 SI链路断链。
S602、 第二基站向第一基站发送指向 PLMN1 的切换请求 (Handover request ) , 该切换请求中携带 PLMN1的标识。
S603、第一基站拒绝该切换请求, 即发送 HANDOVER PREPARATION FAILURE。 进一步的, 可以在 HANDOVER PREPARATION FAILURE中扩 展 cause 值( Cause Value ), 用于指示出第一基站下有哪些运营商出现了断 链。
在本实施例中, 当第一基站下某运营商的网络出现故障后, 若仍有 UE 欲从相邻基站切换至第一基站下的该故障运营商, 那么第一基站将釆取主 动拒绝的方式, 拒绝相邻基站下的 UE所欲进行的这种切换, 以免造成 UE 不断接入又释放等不利后果。 实施例五
与本发明前述的运营商共享网络中的故障处理方法实施例相对应, 本 发明实施例还提供了运营商共享网络中的故障处理装置。
本实施例提供了一种运营商共享网络中的故障处理装置 700 ,参见图 7 所示。 所述装置 700用于第一基站, 在所述第一基站下多个运营商共享网 络, 装置 700可以包括:
故障运营商标识获取单元 701 , 用于获取故障运营商的标识, 所述故 障运营商为所述第一基站下发生了网络故障的运营商;
UE通知单元 702 , 用于通过发送指定消息, 将所述故障运营商的标识 通知所述第一基站下的 UE, 以使所述第一基站下的 UE不再接入所述故障 运营商在所述第一基站下的网络;
其中, 所述指定消息中包含所述故障运营商的标识。
优选的, 所述指定消息为系统信息块 SIB消息, 所述 SIB消息的小区 禁止 cellBarred字段中包含故障运营商列表,所述故障运营商列表中包含所 述故障运营商的标识。
在本实施例或本发明其他某些实施例中, 所述装置 700还可以包括: 相邻基站通知单元, 用于将所述故障运营商的标识通知给与所述第一 基站相邻的第二基站, 以使所述第二基站禁止所述第二基站下的 UE切换 至所述故障运营商在所述第一基站下的网络。
在本实施例或本发明其他某些实施例中, 所述装置 700还可以包括: UE接入阻止单元,用于当接收到与所述第一基站相邻的第二基站发来 的 UE的切换请求时, 拒绝所述 UE的切换请求, 其中, 所述 UE的切换请 求为所述第二基站下的 UE欲切换至所述故障运营商在所述第一基站下的 网络的请求。
此外, 在本实施例或本发明其他某些实施例中, 所述装置 700还可以 包括:
故障检测单元, 用于对所述第一基站下各运营商的网络到核心网的链 路进行心跳检测, 以获知是否有运营商发生了网络故障。
在基站下存在多个运营商共享网络的场景中, 当某个或某些运营商的 网络出现了故障 (如 S1 链路故障) 时, 本实施例可以通过指定消息 (如 SIB消息 ) 将故障运营商的标识通知给基站下的 UE, 使得 UE可以正确区 分出哪些运营商发生了网络故障, 从而避免发生 UE仍试图接入故障运营 商的网络等不正常现象。
