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。
在安全组网架构中, 网元要通过安全网关的防护才可以访问位 于安全域内的网元, 当出现安全网关故障或安全参数配置错误等情 况时。 本发明的实施例提供一种通道建立方法, 参照图 1 所示, 包 括:
101、当操作维护 OM通道不通时,基站发送网际协议安全 IPsec 重协商命令至安全网关, 且重建立具有 Ipsec模式的 OM通道。
其中, 该 OM通道用于基站与操作维护中心之间通信。
102、 当重建立具有 Ipsec模式的 OM通道失败时, 基站发送动 态主机配置协议 ( Dynamic host configuration protocol , 简称 DHCP ) 请求信息至动态主机配置协议服务器 DHCP- Server。
103、 基站接收 DHCP-Server发送的对 DHCP请求信息的回复 报文; 其中, 回复报文中携带配置密钥。
104、 基站将配置密钥与预先存储的 IPsec通道倒换口令进行匹 配。
105、 判断配置密钥与预先存储的 IPsec通道倒换口令是否匹配 成功。
106、当配置密钥与预先存储的 IPsec通道倒换口令匹配成功时, 基站取消对 IPsec端口的绑定, 将传输链路切换到非 Ipsec模式的传 输链路。
具体的, 具有 Ipsec 模式的操作维护通道即该操作维护通道受 IPsec隧道保护, 将传输业务数据加密。 非 Ipsec模式的操作维护通 道即该操作维护通道不受 IPsec保护, 不加密传输业务数据。
本发明的实施例提供的通道建立方法, 通过在安全网关出现故 障或参数配置错误时, 将数据流从 IPsec通道切换到非 Ipsec通道, 减少了业务中断时间, 降低了对基站的维护成本。
本发明的实施例提供一种通道建立方法, 参照图 2所示, 包括:
201、当操作维护 OM通道正常时,基站接收操作维护中心 OMC 发送的 IPsec通道倒换口令并存储该 IPsec通道倒换口令。 其中, 该 IPsec 通道倒换口令是在操作维护中心侧由人工设置 的。 且, 该 IPsec 通道倒换口令的格式可以是字符串, 当 OM 通道 出现故障时, 通过该 IPsec 通道倒换口令可以实现 OM通道从具有 Ipsec模式的传输链路切换到非 Ipsec模式的传输链路。
202、 当 OM通道不通时, 基站发送网际协议安全 IPsec重协商 命令至安全网关, 且重建立具有 Ipsec模式的 OM通道。
其中, OM通道用于基站与操作维护中心之间通信。
OM 通道的 通信状况通过失效对端检测 ( Dead Peer Detection , 简称 DPD ) 来获得。 如果 DPD检测成功, 则说明 OM 重建成功, 如果 DPD检测失败则说明 OM重建失败。
OM通道正常时, 基站与操作维护中心的传输链路为具有 IPsec 模式的 OM通道。 当 OM通道故障后, 基站会首先尝试与安全网关 重协商 IPsec , 如果重协商成功则继续使用具有 IPsec模式的 OM通 道, 如果重协商失败则切换到非 IPsec模式的 OM通道。
203、 当重建立具有 Ipsec模式的 OM通道失败时, 基站发送动 态主机配置协议 DHCP 请求信息至动态主机配置协议服务器 DHCP-Server。
204、 基站接收 DHCP- Server发送的对 DHCP 请求信息的回复 报文; 其中, 回复报文中携带配置密钥。
具体的, 该配置密钥是网络故障后用户手工更改设置的密钥。 且, 该配置密钥是保护向基站发送非法切换命令的主要方式, 因此 配置密钥在用过一次之后端对端修改, 或者周期自动更新。
205、 基站将配置密钥与预先存储的 IPsec通道倒换口令进行匹 配。
具体的, 配置密钥和 IPsec通道倒换口令的格式可以是字符串, 当配置密钥和 IPsec通道倒换口令相同是, 即表示匹配成功。
206、当配置密钥与预先存储的 IPsec通道倒换口令匹配成功时, 基站取消对 IPsec端口的绑定, 将传输链路切换到非 Ipsec模式的传 输链路。
此时的传输链路是非 IPsec 模式的传输链路, 因此不加密传输 业务数据。
207、当配置密钥与预先存储的 IPsec通道倒换口令匹配失败时, 重复执行步骤 202〜205。
208、 当 OM通道恢复正常后,基站接收 OMC发送的配置命令。 具体的, OMC给基站发送配置命令, 是为了通知基站切换到非
IPsec模式传输链路。
209、 基站发送 Ipsec再次协商命令至安全网关。
210、 如果基站再次协商 Ipsec成功, 则建立具体有 Ipsec模式 的 OM通道。
IPsec模式的 OM通道即受 IPsec隧道保护的 OM通道将传输业 务数据加密, 而非 IPsec模式的 OM 通道即不受 IPsec 隧道保护的 OM 通道不加密传输业务数据。 因此基站与操作维护中心的传输链 路是 IPsec模式还是非 IPsec模式跟安全网关有较大的关系。 对数据 的加密主要是由安全网关来进行的, 因此, 将传输链路切换到 IPsec 模式的 OM通道之前, 需要与安全网关进行 IPsec 协商, 只有协商 成功才可以切换到 IPsec模式的 OM通道。
本发明的实施例提供的通道建立方法, 通过在安全网关出现故 障或参数配置错误时, 将数据流从 IPsec通道切换到非 Ipsec通道, 减少了业务中断时间, 降低了对基站的维护成本。 进而, 可以提升 整个网络的可靠性。
