为了更清楚地说明本发明实施例的技术方案， 下面将对实施例或现有技 术描述中所需要使用的附图作筒单地介绍， 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 3是本发明实施例的另一种双网备份的方法的示意流程图。
图 4是本发明实施例的双网备份的设备的示意框图。
图 5是本发明实施例的双网备份的另一设备的示意框图。
图 6是本发明实施例的双网备份的另一设备的示意框图。 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做出创 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。
本发明的技术方案， 可以应用于各种制式的通信系统， 例如： 全球移动 通信系统（ GSM, Global System of Mobile communication ),码分多址（ CDMA, Code Division Multiple Access ) 系统， 宽带码分多址（ WCDMA, Wideband Code Division Multiple Access Wireless ),通用分组无线业务 ( GPRS, General Packet Radio Service )等， 其中 WCDMA和 GPRS又称为 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 )。
用户设备 （ UE , User Equipment ) , 也可称之为移动终端 （ Mobile Terminal ),移动用户设备等， 可以经无线接入网（例如， RAN, Radio Access Network )与一个或多个核心网 （ Core Network )进行通信， 用户设备可以是 移动终端， 如移动电话（或称为"蜂窝"电话）和具有移动终端的计算机， 例 如， 可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置， 它们与无线接入网交换语音和 /或数据。
基站，可以是 GSM或 CDMA中的基站（ BTS , Base Transceiver Station ), 也可以是 WCDMA中的基站（ NodeB );基站控制器，可以是 GSM或 CDMA 中的基站控制器（Base Station Controller, BSC ), 还可以是 WCDMA中的 RNC ( Radio Network Controller )。 GSM和 UMTS等制式属于无线范畴， 本 发明实施例发明可以用于 GSM制式的无线网络备份， 也可以用于其它制式 的无线网络备份。 本发明并不限定， 但为描述方便， 下述实施例以 GSM的 BSC, BTS等为例进行说明。
另外， 本文中术语"系统"和"网络"在本文中常被可互换使用。 本文中术 语"和 /或"， 仅仅是一种描述关联对象的关联关系， 表示可以存在三种关系， 例如， A和 /或 B , 可以表示： 单独存在 A , 同时存在 A和 B , 单独存在 B 这三种情况。 另外， 本文中字符 "/" , 一般表示前后关联对象是一种 "或" 的关系。
现有提升移动网络可靠性的技术主要有容灾备份。 一种技术中， 当主用 基站控制器宕机时， 则备用基站控制器接管主用基站控制器的业务。 该技术 是基站控制器级的， 对其它网元而言， 主用基站控制器与备用基站控制器是 相同的，主用基站控制器与当前状态为备用状态的基站控制器具有相同的 IP 地址， 且同一时间只有一个基站控制器工作。 如果基站控制器正常工作 , 然而基站控制器所辖的基站或小区发生了故 障， 举例来说， 如载频故障或 RSL ( Radio Signaling Link, 无线信号链路） 故障等， 则仍然会导致该网络的小区级的业务中断。 可见， 通过这种仅在基 站控制器级备份的技术， 移动网络的可靠性不能够得到很好地保障。 此外， 同一时间只有一个基站控制器工作， 那么处于备用状态的基站控制器则闲 置， 无法充分发挥设备作用， 浪费了资源。
在另一种技术中， 进行站点级双网备份。 此时， 当主用网络和备用网络 切换时， 指的是主用网络的基站和备用网络的基站之间的切换。 例如， 当主 用网络的基站控制器得知所辖的基站将中止工作时，通知备用网络的基站控 制器， 并关闭主用网络的基站的功率发射； 备用网络的基站控制器在收到通 知后， 通知备用网络的基站启动工作。
该技术是基站级的技术， 只有当基站完全终止工作时， 另一套网络的基 站才会启用。 举例来说， 只有当基站所有载频故障或基站主控单元故障时， 才进行主备切换， 对于已经故障的小区无法实现及时备份。 因此该技术不能 够很好地保证网络正常工作。 此外， 由于同一时间点只有一套网络工作， 备 用网络的基站等无法充分发挥设备作用， 浪费了资源。
本发明实施例提供了一种双网备份的方法， 能够以小区为单位充分地保 障移动网络可靠性。
图 1是本发明实施例的一种无线通信系统 10的组网示意图。 本发明实 施例中的双网是指无线通信系统 10 包括的主用网络设备和备用网络设备。 主用网络设备包括： 主用基站控制器 11和所辖的主用基站 12。 其中， 图 1 中还示出主用基站 12所辖主用小区 13。 备用网络设备包括： 备用基站控制 器 14和所辖的备用基站 15。 其中， 图 1中还示出备用基站 15所辖备用小 区 16。 主用基站控制器 11和备用基站控制器分别连接到核心网 18。
本发明实施例中双网备份的方法是根据网络可用状态， 进行主用网络和 备用网络之间的切换。主用网络和备用网络之间的切换是指主用网络的主用 小区和备用网络的备用小区的工作状态之间的切换。 例如， 从主用网络切换 到备用网络， 则备用网络的备用小区 16主导工作而主用网络的主用小区 13 不工作； 从备用网络切换到主用网络， 则主用网络的主用小区 13主导工作 而备用网络的备用小区 16辅助工作或不工作。
通过生成主备小区绑定关系， 同一路段， 由一对主用小区 13和备用小 区 16 同时覆盖， 主备小区之间的对应关系为一对一。 一个主用基站控制器 所辖的小区中， 可以有一部分小区配置为具有主备小区绑定关系的主用小 区， 同时其余的小区可以做为独立小区 17存在。 备用基站控制器的情况类 似，备用基站控制器所辖的小区中既可以有备用小区，也可以有独立小区 17。
主用基站控制器 11 和备用基站控制器 14可以同属一个核心网或不同 的核心网， 通过 IGR-G ( Interface Between two RNC, 基站控制器之间的接 口）经核心网 18连接。。 出于筒洁， 本发明实施例中仅以核心网 18示意上 述任一种情况， 其中各网元间的通信协议与现有技术相同。
同一网络中基站控制器和核心网之间的接口为 A口。 基站控制器通过 OML ( Operation Maintenance Link, 操作维护链路） 向基站发送控制消息、 记录日志， 包括告警等信息。

图 3是本发明实施例的另一种双网备份的方法 300的示意流程图， 包括 以下内容。
S305 , 生成主用小区和备用小区的——对应关系。
如图 1所示， 同一路段由主用、 备用两个小区同时覆盖。 可选的， 主用 基站的小区中除包括主用小区外还可以包括一些独立小区， 或备用基站的小 区中除包括备用小区外也可以包括一些独立小区。独立小区是主用小区和备 用小区之外的小区。
S310, 为主用小区和备用小区配置不同的主 B载频。 承载小区 BCCH ( Broadcast Channel, 广播信道 ) 的载频， 称为主 B载 频， 主 B载频的频点称为主 B频点。 一个小区的所有载频中除主 B载频之 外的其他载频， 称为非主 B载频。
在本发明实施例双网备份方法中， 利用了共享非主 B频点（SNB, Share Non BCCH )功能， 可以在主用网络的一个主用小区载频全部故障时， 备用 网络的对应的备用小区的备用载频接替主用小区的非主 B载频工作，恢复部 分业务容量； 此外主用网络工作时， 备用网络的备用小区的主 B载频工作， 可以承载部分业务。 SNB功能的技术中， 由于主用网络的主用小区和备用网 络的备用小区——对应， 且采用了不同的主 B载频， 可以同时工作， 即避免 了相互干扰， 也避免了频点浪费。
此外， 将所述备用小区的非主 B载频配置为所述主用小区的非主 B载 频的子集， 可以节省频率资源。
S315 , 进行配置核查以保证主备关系正常工作。
生成主备小区关系且配置了各小区的频点后， 首先进行配置核查， 用于 保证主用网络和备用网络的关系是否正常工作。优选地，可以进行定时核查。 通过检查主用小区和备用小区， 如果发现配置错误可以通过告警提示用户。 举例来说， 基站控制器通过定期握手即相互发送核查消息， 检查主备关系的 配置是否正确以及当前主备网络工作状态是否正常。核查消息包括接收端小 区的标识以及发送端小区的标识以及发送端小区配置的主备类型（主用小区 或备用小区）、 发送端小区的运行状态 （主用或备用）等。 接收端根据发送 小区的标识查看在本端是否有小区与发送端小区配置主备关系，还会根据发 送端小区配置的主备类型与本端小区的主备类型对比判断是否同时配置为 主用小区或同时配置为备用小区。 这些均属于配置检查的范围。 此外， 还会 根据发送端小区的运行状态判断当前网络是否均是主用状态或备用状态。如 果是配置检查出错误则上报配置错误告警提示用户。 如果是运行状态有误， 则根据判决原则判断某一端小区升为主用， 另一端小区降为备用， 从而保证 网络中一主一备的工作关系。上述配置检查在确定主用网络和备用网络后可 以按时进行。
接下来， 首先说明从主用网络向备用网络切换时的双网备份方法。
S320, 主用网络主导工作时， 主用小区所有载频均工作， 备用小区只有 主 B载频工作。 这是主用网络主导工作时各小区的工作状态。 利用现有技术， 可以通过 网络无线参数规划使得用户设备优先驻留在主用小区，发起业务时优先使用 主用小区的信道。
S330, 查询网络可用状态。
可以通过基站控制器之间的通信， 查询网络可用状态。 优选地， 可以进 行定时查询。 通过网络可用状态获知小区故障与恢复的情况， 进而执行主用 网络和备用网络的切换， 作为示例此处列举了几种， 本发明实施例包括但不 限于以下情况。在本发明实施例中主用网络和备用网络之间的切换是指主用 网络的主用小区和备用网络的备用小区的工作状态之间的切换。
查询网络可用状态可以获知所有主用小区和备用小区的可用状态。 当小 区主 B载频正常工作、 A口正常且 OML正常时， 确认为小区状态为可用， 否则确认小区故障。
a )如果任一小区的主 B载频故障， 则认为该小区故障。
当主用网络工作时， 主用小区的主 B载频故障， 备用小区的主 B载频 正常， 则从主用网络切换到备用网络。
b )如果小区的主 B载频正常， 但小区所在基站控制器的 OML故障， 且已经过了 OML断链延迟保护时间， 则认为该小区故障。
当主用网络工作时， 主用小区的主 B载频正常，但主用小区所在主用基 站的 OML故障， 且已经过了 OML断链延迟保护时间， 则认为该主用小区 故障， 则从主用网络切换到备用网络。
c )如果 A口链路故障， 则认为该基站控制器下所有小区故障。
当主用网络工作时，主用基站控制器与核心网连接的 A口链路故障， 则 主用基站控制器与备用基站控制器之间的 IUR-G故障无法通信，则主用基站 控制器所辖的所有主用小区故障， 则从主用网络切换到备用网络。
d )如果基站控制器故障， 则认为该基站控制器下所有小区故障。
当主用网络工作时， 主用基站控制器故障， 则主用基站控制器与备用基 站控制器之间的 IUR-G故障无法通信，则主用基站控制器所辖的所有主用小 区故障， 则从主用网络切换到备用网络。
当主用网络出现的情形满足上述条件 a )至 d )之一时， 均可以启用备 用网络接替主用网络工作， 由此可以将可靠性粒度细化至小区， 从而最大程 度保证网络覆盖无中断。 与现有基站级备份技术相比， 现有技术需要基站控制器通过 OML与基 站交互，将主用网络降为备用网络时需要去激活备用基站或者下发关载频消 息， 并且依赖备用基站控制载频的发功状态。 然而， 本发明实施例不依赖 OML, 也不依赖基站的行为。 因为主 B的频点不一致， 主 B频点同时发功 或发送广播消息不会产生干扰， 只要在基站控制器侧控制载频业务接入即可 实现主备状态的切换。 本发明实施例的实现方式只需基站控制器操作， 更为 筒便。
S340, 当确认主用小区故障， 则从主用网络切换到备用网络
主用基站控制器检测到主用小区故障， 则启动切换定时器， 将该主用小 区业务切换到其他小区， 然后向备用小区发送倒换请求， 并启动倒换等待定 时器。基站控制器在切换定时器的计时范围内将故障的主用小区上的话务切 换到邻区， 该邻区可以是内部邻区也可以是外部邻区， 从而最大程度保证通 话不受影响。 该话务切换指话务的转移， 与主备网络的切换相区别。 话务切 换完成后会通知对端小区升为主用， 同时启动倒换等待定时器， 对端小区升 为主用完成后会给本端回响应消息。主用小区收到倒换响应后停止倒换等待 定时器， 上 倒换告警显示倒换成功， 完成一次握手， 且将主用小区的所有 载频配置为不工作。本次握手如果在倒换定时器超时仍未完成则认为主备网 络切换失败， 上报的倒换事件告警会显示倒换超时。 该倒换等待定时器主要 用于保证主备网络切换在一定时间内， 倒换结果均在倒换事件告警中显示。
备用基站控制器的备用小区收到倒换请求后且判断备用小区状态可用， 则备用小区激活所有载频并设置为工作状态， 上 倒换告警， 回复倒换响应 给主用小区。 当所述备用小区的主 B载频正常、所述备用小区所在的基站的 运行维护链路 OML链路正常、 所述备用基站控制器的 A口链路正常且所述 备用基站控制器正常时， 备用小区状态可用。
但对于主用基站控制器故障的情形， 主用基站控制器和备用之间的握手 消息丟失， 则备用小区直接将所有载频设置为工作状态， 而认为主用小区不 再工作。 这样， 当主用小区故障时， 由于覆盖区域相同的备用小区启用， 业 务最大程度不受损。 而独立小区故障时， 由于没有双网备份的功能， 独立小 区覆盖区域的业务受损。 比起现有技术中基站控制器级或站点级的双网备份 方法， 本发明实施例的网络可靠性可以达到小区一级， 从而最大程度保证业 务不受影响。 接下来， 再说明从备用网络向主用网络切换时的双网备份方法。
S345 , 备用网络主导工作时， 备用小区所有载频均工作， 主用小区所有 载频不工作。
这是备用网络主导工作时各小区的工作状态。
S330, 查询网络可用状态。
该步骤同前。 查询网络可用状态可以获知所有小区， 例如主用小区、 备 用小区或独立小区的可用状态。当小区主 B载频正常工作、 A口正常且 OML 正常时， 确认为小区状态为可用， 否则确认小区故障。
S350, 当确认主用小区可用， 则从备用网络切换到主用网络。
当查询到主用小区的状态从故障恢复为可用， 则通过主用基站控制器和 备用基站控制器之间的握手， 将备用网络切换到主用网络。 过程与 S340相 反， 内容相似。 从备用网络切换到主用网络后， 主用小区的所有载频工作， 而备用小区仅主 B载频工作。
本发明实施例通过绑定主用小区和备用小区的对应关系， 为主用小区和 备用小区的配置不同的主 B载频， 且根据主用网络或备用网络状态， 配置主 用小区和备用小区的相应载频工作， 且根据网络可用状态， 进行主用网络和 备用网络之间的切换， 从而将移动网络可靠性的保障提高到小区一级， 且在 主用网络工作时，备用小区的主 B载频工作， 充分发挥了备用设备的资源作 用。
