在无线共享网络中， 如通用移动通信系统 （UMTS , Universal Mobile Telecommunications System )中，陆地无线接入网络（ UTRAN, UMTS Terrestrial Radio Access Network ) 可以同时连接多个运营商的 核心网 （CN， Core Net )设备， 实现 UTRAN为多个运营商共享。 UTRAN为每个连接的 CN设备分配一个唯一的网络资源标识（ NRI, Network Resource Identifier )，用户终端呼叫时上报 NRL然后 UTRAN 根据 NRI将用户终端呼叫路由到 NRI所对应的 CN设备， 所述 CN 设备对应的运营商执行相应计费且对呼叫业务进行有效的控制。因而 用户终端在接入 UTRAN时，有可能不通过自己所属的运营商的载频 而通过其他运营商的载频接入 UTRAN。
在另一现有技术中，共享的无线接入网的基站控制器根据用户终 端的国际移动用户终端标识 （IMSI, International Mobile Subscriber Identity )解析出运营商标识，将用户终端呼叫路由到用户终端所属的 CN设备， 所述 CN设备对应的运营商执行相应计费且对呼叫业务进 行有效的控制。 因而用户终端在接入共享的无线接入网时， 有可能不 通过用户终端所属运营商的载频而是通过其他运营商的载频接入共 享无线网络。
发明人发现， 上述的现有技术存在这样一个问题， 用户终端可能 通过其他运营商的载频接入无线共享网络，用户终端占用了其他运营 商的载频专属资源，但其他运营商却无法监督到这种情况， 因而无法 对这种情况下用户终端的呼叫业务执行相应计费，也无法对这些呼叫 业务进行有效地控制。
而在有线共享网络中，端口资源可能是运营商自己部署的专属资 源。 例如多运营商共享电信接入设备宽带远程接入服务器（BRAS, broadband remote access server )、 部署在公共场所的 ADSL端口， 或 WLAN端口等， 部署这些端口资源需要耗费大量成本。 发明人发现， 现有技术存在这种问题，用户终端通过这些端口接入业务时根据用户 帐号来选择运营商网络，导致部署这些端口资源的运营商无法对这些 呼叫业务进行有效控制。
从上面可以看出，现有技术中用户终端无论是接入无线共享网络 还是有线共享网络时，用户终端可能通过其他运营商的专属资源接入 共享网络，但是拥有这些专属资源的运营商却无法对这些呼叫业务进 行有效控制。 发明内容 为解决上述技术问题，本发明实施例的一方面提供了一种路由方 法：
一种路由方法， 应用于多运营商共享网络， 其特征在于， 在所述 共享网络中，共享的电信设备的资源配置数据库中包括共享资源所属 的运营商信息，所述共享的电信设备的连接路由表中包括到各运营商 的专属网络的路由信息，所述路由信息包括运营商信息，该方法包括： 当接收到用户终端的业务请求信息时，根据所述用户终端占用的 共享资源，从所述资源配置数据库中获取所述占用的共享资源所属的 运营商信息；
根据所述占用的共享资源所属的运营商信息，在所述连接路由表 中匹配对应的路由信息，根据匹配成功的路由信息转发所述用户终端 的业务请求信息。 本发明实施例的另一方面，提供了一种路由装置，应用于共享的 电信设备， 该装置包括：
资源配置数据库， 包含资源所属的运营商信息；
连接路由表模块，包含与多运营商的专属网络连接的路由所属的 运营商信息；
获 莫块，根据用户终端的呼叫业务请求信息所占用的运营商专 属资源，从所述资源配置数据库中获取所述运营商专属资源所属的运 营商信息；
匹配模块，将所述运营商专属资源所属的运营商信息与所述连接 路由表中对应路由所属的运营商信息进行匹配；
转发模块，用于从所述匹配成功的运营商信息对应的路由转发用 户终端的呼叫业务请求信息。
本发明实施例的又一方面，提供了一种通信系统， 包括上述路由 装置。
由以上本发明实施例提供的技术方案可见， 本发明实施例，在网 络设备共享时， 当运营商的专属资源被其他运营商的用户终端占用 时，共享的电信设备能将用户终端的呼叫业务请求信息转发至专属资 源所属的运营商专属网络，专属资源所属的运营商就能对用户终端的 呼叫业务情况进行记录， 执行相应计费， 并能对这些呼叫业务进行有 效地控制。 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性的前提下，还可以根据这 些附图获得其他的附图。 图 1是一实施例提供的路由方法流程示意图；

具体实施方式 为了使本技术领域的人员更好地理解本发明方案，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 做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明 保护的范围。
本发明的各实施例中，共享设备指可以由不同运营商的签约用户 使用的电信设备；共享资源指部署于共享设备或者由共享设备管理的 通信资源， 可以由属于不同运营商的签约用户使用， 如载频资源、 端 口资源等。 通常情况下， 共享资源属于某一运营商， 如由该运营商购 买所得或者投资部署的， 也是该运营商的专属资源。
以下介绍路由方法的一个实施例，该实施例可应用于多运营商共 享网络， 图 1示出了该实施例的流程示意图， 包括：
步骤 101 : 共享的电信设备在资源配置数据库中增加资源所属的 运营商信息。
所述资源包括但不限于无线接入资源和有线接入资源，无线接入 资源包括扇区， 载频等资源，有线接入资源包括各种有线通信端口资 源。
所述共享的电信设备包括多运营商共享的无线接入电信设备和 多运营商共享的有线接入电信设备，所述无线接入电信设备包括无线 基站子系统（BSS， Base Station Subsystem )设备， 所述有线接入电 信设备包括宽带远程接入服务器 BRAS设备。
进一步的， 在资源配置数据库中， 可以按照资源标识进行关键字 索引， 以便于按照资源标识进行数据库检索查询。
所述运营商信息可以是运营商标识，也可以是由权威机构统一分 配的运营商编码信息。
在资源配置数据库中增加资源所属的运营商信息，即表示所述资 源为所述运营商信息对应的运营商的专属资源。
步骤 102: 共享的电信设备在与多运营商的专属网络的连接路由 表中增加路由所属的运营商信息。
所述运营商的专属网络指的是运营商专用，还未对其它运营商共 享的网络部分。
所述共享的电信设备至少与一个运营商的专属网络有连接。 所述连接路由表包括但不限于 TDM链路方式的连接路由表， IP 方式的连接路由表。
在连接路由表中增加连接路由所属的运营商信息，即表示所述连 接路由连接的目的网络为所述运营商信息对应的运营商的专属网络。
在连接路由表中， 可以按照运营商信息进行索引， 以便于按照运 营商信息进行匹配过程的处理。
所述运营商信息可以是运营商标识，也可以是由权威机构统一分 配的运营商编码信息。所述连接路由表中的运营商信息与所述资源配 置数据库中的运营商信息所使用的表示形式保持一致。
步骤 103: 共享的电信设备根据用户终端的呼叫业务请求信息所 占用的运营商专属资源，从所述资源配置数据库中获取所述运营商专 属资源所属的运营商信息；
用户终端的呼叫业务请求信息中可以包含所述用户终端占用的 运营商专属资源信息，也可以不包含所述用户终端占用的运营商专属 资源信息。
若用户终端的呼叫业务请求信息中包含所述用户终端占用的运 营商专属资源信息，则系统直接从呼叫业务请求信息中获取所述用户 终端占用的运营商专属资源信息。
若用户终端的呼叫业务请求信息中不包含所述用户终端占用的 运营商专属资源信息，则系统可以根据接收到所述呼叫业务请求信息 的通信接口地址来获取所述用户终端占用的运营商专属资源信息。
从资源配置数据库中获取资源所属的运营商信息，就是按照所述 用户终端占用的运营商专属资源信息在资源配置数据库中进行查询， 得到所述运营商专属资源对应的记录，从所述记录中获取的运营商信 息即为运营商专属资源所属的运营商信息。
步骤 104: 共享的电信设备将所述运营商专属资源所属的运营商 信息与所述连接路由表中对应路由所属的运营商信息进行匹配，从匹 配成功的运营商信息对应的路由转发所述用户终端的呼叫业务请求 信息。
所述匹配处理是在所述连接路由表中找出与所述资源所属的运 营商信息一致且连接状态正常的路由记录。
匹配成功的路由记录可以是一个， 也可以是多个， 也可以没有匹 配成功的路由记录。
若匹配成功的路由记录是一个，则从此路由记录对应的路由转发 所述用户终端的呼叫业务请求信息。
若匹配成功的路由记录是多个，则可以采用某一种选择策略选择 其中一个匹配成功的路由记录，从此路由记录对应的路由转发所述用 户终端的呼叫业务请求信息。选择策略可以是选择第一个匹配成功的 路由记录， 也可以选择其中任意一个匹配成功的路由记录， 或者根据 路由的权重评价信息，从此路由记录中选择一个权重评价信息最佳的 路由记录。所述路由的权重评价信息可以是表示路由忙闲程度的负荷 信息。
若匹配成功的路由记录没有，则可以使用系统指定的一个默认路 由转发所述用户终端的呼叫业务请求信息；也可以选择所述连接路由 表中任意一个的路由记录；也可以使用所述用户终端所属的运营商信 息， 与所述连接路由表中对应路由所属的运营商信息进行匹配， 从匹 配成功的路由转发所述用户终端的呼叫业务请求信息。都不影响本实 施例的实现。
所述转发的所述用户终端的呼叫业务请求信息可以是呼叫连接 请求消息， 也可以是资源占用通知消息。 所述呼叫连接请求消息和所 述资源占用通知消息中都携带所述用户终端的用户信息和所述用户 终端所占用的资源信息。
若转发的所述用户终端的呼叫业务请求信息是呼叫连接请求消 息，表示将所述用户终端的呼叫与所述路由对应的运营商专属网络建 立连接，其结果是所述用户终端的呼叫话路会从所述共享的电信设备 接入到所述路由对应的运营商专属网络，所以所述运营商专属网络可 以对所述用户终端的呼叫进行各种控制和对通话情况进行记录，执行 计费。
若转发的所述用户终端的呼叫业务请求信息是资源占用通知消 息，表示只是将所述用户终端的呼叫业务请求信息占用运营商专属资 源这一事件上 给所述专属资源所属的运营商专属网络，所述用户终 端的呼叫话路可以不从所述共享的电信设备接入到所述路由对应的 运营商专属网络， 这样可以减少话路迂回， 提高通信的效率。
所述资源占用通知消息可以发送一次， 也可以发送多次。 比如在 所述用户终端的整个呼叫业务连接过程中， 每隔一段时间发送一次， 4艮告所述用户终端占用运营商专属资源的情况。在所述用户终端的呼 叫业务连接释放时， 可以发送资源占用通知消息，报告所述用户终端 已经释放， 不再占用运营商专属资源的情况。通过所述资源占用通知 消息，所述资源对应的运营商专属网络可以对所述用户终端的呼叫通 话情况进行记录， 执行计费， 并且进行各种控制， 所述控制指令通过 响应消息发送给所述共享的电信设备， 由所述共享的电信设备来执 行。
以下介绍本发明实施例提供的路由方法的第二个方法实施例，该 实施例应用于多运营商无线共享网络， 图 2a示出了该实施例的网络 示意图，运营商 1的用户终端通过载频 2接入共享的无线基站子系统 设备，再通过路由 2接入运营商 2的核心网络，再转发至运营商 1的 核心网络。 图 2b示出了该实施例的流程示意图， 包括： 步骤 201 :共享的无线基站子系统 BSS设备在载频资源配置数据 库中增加载频资源所属的运营商信息；
所述共享的无线基站子系统 BSS设备是指多运营商共享的无线 基站子系统 BSS设备，可以是 GSM, CDMA, WCDMA, TD-SCDMA, WiMAX的无线基站子系统。无线基站子系统 BSS设备可以包括基站 收发台（ BTS， Base Transceiver Station )设备、无线基站控制器（ BSC, Base Station Controller )设备。
所述载频资源配置数据库位于无线基站控制 BSC设备中。
载频资源是无线网络运营商向政府购买的， 是运营商的专属资 源， 不同的运营商有不同的载频资源。 例如载频频段为 870MHz-880MHz 的载频资源为运营商 1 所属， 载频频段为 900MHz-910MHz的载频资源为运营商 2所属。
所述运营商信息可以是运营商标识，也可以是由权威机构统一分 配的运营商编码信息。
在无线基站控制器设备的载频资源配置数据库中增加载频资源 和载频资源对应的运营商信息， 如下表所示， 这里仅以 2个运营商为 例进行说明。
Figure imgf000009_0001
载频 1属于 870MHz-880MHz频段内的载频资源； 载频 2属于 900MHz-910MHz频段内的载频资源。
用 户 的无线终端为双模终端， 同 时支持载频频段 870MHz-880MHz和 900MHz-910MHz，在两个载频频段都可以接入。 这样， 用户的无线终端即可以从载频 1接入， 也可以从载频 2接入。 这里^殳用户终端为运营商 1的用户终端。
步骤 202:共享的无线基站子系统 BSS设备在与运营商 1和运营 商 2的 CN网络的连接路由表中增加路由所属的运营商信息；
所述连接路由表如下表所示：
路由 运营商信息 路由 1 运营商 1
路由 2 运营商 2 路由 3 运营商 2 步骤 203:共享的无线基站子系统 BSS设备接收用户终端的呼叫 业务请求信息， 从呼叫业务请求信息中获取用户终端的接入载频资 源。
共享的无线基站子系统 BSS设备从呼叫业务请求信息中获取接 入载频信息，此接入载频信息即为用户终端此次呼叫所占用的载频资 源。
步骤 204:共享的无线基站子系统 BSS设备根据所述用户终端的 接入载频资源从载频资源配置数据库中获取用户终端的接入载频资 源所属的运营商信息。
例如运营商 1的用户终端的接入载频为载频 2， 根据载频 2查询 载频资源配置数据库， 得知载频 2所属的运营商信息为运营商 2。 这 样运营商 1的用户终端就占用了运营商 2的载频资源。
步骤 205:共享的无线基站子系统 BSS设备将所述用户终端的接 入载频所属的运营商信息与所述连接路由表中对应路由所属的运营 商信息进行匹配，从匹配成功的运营商信息对应的路由转发呼叫业务 请求信息。
所述转发的呼叫业务请求信息为呼叫连接请求消息，所述呼叫连 接请求消息中包含所述用户终端的用户信息和所述用户终端所占用 的资源信息。 这里所述用户终端的用户信息具体为用户终端的 IMSI 标识，所述用户终端所占用的资源信息为用户终端的接入载频资源信 如上，运营商 1的用户终端通过载频 2发起呼叫业务， 所述载频 2所属的运营商信息为运营商 2，这时所述共享的无线基站子系统 BSS 设备用运营商 2信息在所述连接路由表中进行匹配， 路由 2和路由 3 都匹配成功。 所述共享的无线基站子系统 BSS设备可以在路由 2和 路由 3任选一个路由， 来转发所述呼叫业务请求信息。
运营商 2的核心网络 CN接收到所述呼叫业务请求信息，所述呼 叫业务请求信息为呼叫连接请求消息，运营商 2的 CN为此呼叫建立 连接， 并将所述呼叫业务请求信息继续转发给运营商 1的 CN， 从而 完成整个呼叫话路的建立。运营商 2的 CN可以对此呼叫进行通话情 况记录， 执行计费， 和进行各种控制。
从上面可以看出，本发明实施例中无论用户终端是运营商 1的用 户终端还是运营商 2的用户终端，只要通过运营商 2的载频资源接入 的， 共享的无线基站子系统 BSS设备就将呼叫业务请求信息转发到 运营商 2的 CN， 运营商 2的 CN可以对此呼叫进行通话情况记录， 执行计费， 和进行各种控制。 当运营商的载频资源被其他运营商的用 户终端占用时， 运营商也能实施后续相应的计费和有效的控制。
以下介绍本发明实施例提供的路由方法的第三个实施例，该实施 例应用于多运营商有线共享网络， 图 3a示出了该实施例的网络示意 图，运营商 1的用户终端通过通信端口 2接入共享的宽带远程接入服 务器 BRAS设备， 再通过路由 2接入运营商 2的鉴权， 授权，认证网 络， 再转发至运营商 1的鉴权， 授权， 认证网络。 图 3b示出了该实 施例的流程示意图， 包括：
步骤 301：共享的宽带远程接入服务器 BRAS设备在通信端口资 源配置数据库中增加通信端口资源所属的运营商信息；
所述共享的宽带远程接入服务器 BRAS设备为多运营商共享的 有线宽带远程接入服务器 BRAS设备。所述通信端口资源配置数据库 位于宽带远程接入服务器 BRAS设备中。
所述通信端口资源包括但不限于以太网接入通信端口资源、 ADSL接入通信端口资源或 WLAN接入通信端口资源。
所述通信端口资源作为有线网络运营商的专属资源，不同的运营 商有不同的通信端口资源。例如： 宽带远程接入服务器 BRAS设备的 通信端口号为 1-50的通信端口为运营商 1所属，通信端口号为 51-100 的通信端口为运营商 2所属。
所述运营商信息可以是运营商标识，也可以是由权威机构统一分 配的运营商编码信息。
在所述共享的宽带远程接入服务器 BRAS设备的通信端口资源 配置数据库中增加通信端口所属的运营商信息， 如下表所示， 这里仅 以 2个运营商为例来说明。
Figure imgf000012_0001
通信端口 1属于通信端口号为 1-50内的通信端口资源； 通信端 口 2属于 51-100内的通信端口资源。
用户终端既可以从通信端口 1接入， 也可以从通信端口 2接入， 这里^殳用户终端为运营商 1的用户终端。
步骤 302: 共享的宽带远程接入服务器 BRAS设备在与运营商 1 和运营商 2的鉴权， 授权， 计费（AAA, Authentication, Authorization, Accounting ) 网络的连接路由表中增加路由所属的运营商信息。
所述连接路由表如下表所示:
Figure imgf000012_0002
步骤 303：共享的宽带远程接入服务器 BRAS设备接收用户终端 的呼叫业务请求信息，根据呼叫业务请求信息获取用户终端的接入通 信端口资源。
用户终端的呼叫业务请求信息中不包含所述用户终端接入的通 信端口资源，所述共享的宽带远程接入服务器 BRAS设备可以根据接 收到所述呼叫业务请求信息的通信接口地址来获取所述用户终端的 接入通信端口资源。
步骤 304:共享的宽带远程接入服务器 BRAS设备根据所述用户 终端的接入通信端口资源从通信端口资源配置数据库中获取用户终 端的接入通信端口资源所属的运营商信息。
例如用户终端的接入通信端口为通信端口 2， ^居通信端口 2查 询通信端口资源配置数据库，得知通信端口 2所属的运营商信息为运 营商 2。这样运营商 1的用户终端就占用了运营商 2的通信端口资源。 步骤 305:共享的宽带远程接入服务器 BRAS设备根据所述用户 终端的接入通信端口所属的运营商信息与所述连接路由表中路由所 属的运营商信息进行匹配，从匹配成功的运营商信息对应的路由转发 呼叫业务请求信息。
所述转发的呼叫业务请求信息可以为 AAA认证请求消息， 也可 以为资源占用通知消息。 所述 AAA认证请求消息和所述资源占用通 知消息中都携带所述用户终端的用户信息和所述用户终端所占用的 资源信息，这里所述用户终端的用户信息具体为用户的域名，用户名， 密码信息，所述用户终端所占用的资源信息为用户终端的接入通信端 口资源信息。
如上， 用户终端通过通信端口 2拨号发起上线请求， 所述通信端 口 2所属的运营商信息为运营商 2， 这时所述共享的宽带远程接入服 务器 BRAS设备用运营商 2信息在所述连接路由表中进行匹配，路由 2和路由 3都匹配成功。所述共享的宽带远程接入服务器 BRAS设备 可以在路由 2和路由 3任选一个路由，来转发所述呼叫业务请求信息。
运营商 2的 AAA网络接收到所述呼叫业务请求信息， 所述呼叫 业务请求信息为资源占用通知消息， 运营商 2的 AAA网络为所述用 户终端进行准入处理， 若不准入， 则通知所述共享的宽带远程接入服 务器 BRAS设备拒绝所述用户终端的上线请求；若准入， 则可以构造 认证请求消息转发给所述用户终端所属的运营商 1的 AAA网络进行 认证和授权，或者通知所述共享的宽带远程接入服务器 BRAS设备构 造认证请求消息直接发送到所述用户终端归属的运营商 1的 AAA网 络进行认证和授权。 运营商 2的 AAA网络可以通过所述共享的宽带 远程接入服务器 BRAS设备转发的资源占用通知信息，对此呼叫进行 通话情况记录， 执行计费， 和进行各种控制， 所述控制指令通过响应 消息发送给所述共享的宽带远程接入服务器 BRAS设备，由所述共享 的宽带远程接入服务器 BRAS设备来执行。所述控制可以包括： 强制 释放端口占用， 端口速率调整等各种控制。
从上面可以看出，本发明实施例中无论用户终端是运营商 1的用 户终端还是运营商 2的用户终端，只要通过运营商 2的通信端口资源 接入的，共享的宽带远程接入服务器 BRAS设备就将呼叫业务请求信 息转发到运营商 2的 AAA网络， 运营商 2的 AAA网络可以对此呼 叫进行通话情况记录， 执行计费， 和进行各种控制。 当运营商的通信 端口专属资源被其他运营商的用户终端占用时，运营商也能实施后续 相应的计费和有效的控制。
从上面的描述可以看出， 专属资源属于一个运营商，但是可以由 别的运营商的用户使用。
专属资源所属的运营商，通过共享设备转发的信息， 可以了解占 用该专属资源的用户所属的运营商，从而可以根据实际情况计费， 然 后再将相应的信息转发到用户所属的运营商。
进一步的， 为了提升效率， 可以仅将控制面的信令转发到专属资 源所属的运营商，而用户面的数据可以由共享设备直接路由到用户所 属的运营商。
通过上述本发明实施例的实施方式的描述可知，本领域的技术人 员可以清楚地了解到本发明实施例可借助软件加必需的通用硬件平 台的方式来实现。基于这样的理解， 本发明实施例的技术方案本质上 或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来， 该计算机软件产品可以存储在存储介质中， 如 ROM/RAM、磁碟、 光 盘等， 包括若干指令用以使得一台计算机设备（可以是个人计算机， 服务器， 或者网络设备等）执行本发明实施例或者实施例的某些部分 所述的方法。
