本发明实施例提供一种路由的方法, 该方法的具体实施流程如图 1 所 示, 包括:
歩骤 S101、 接收用户的呼叫请求。
歩骤 S102、 根据所述呼叫请求中的用户参数到网元路由映射表查询目的 网元。
其中, 用户参数根据接收用户呼叫请求的设备的不同包含不同的参数类 型, 如果接收用户的呼叫请求的是 MSS , 则所述用户参数包括: 用户所属号 段、 用户签约业务键以及用户签约触发的 OCG的 GT地址; 如果接收用户端 呼叫请求的是 GGSN, 则所述用户参数包括: 用户所属号段及服务信息。 网元路由映射表是预先设置的, 该网元路由映射表包括目的网元地址及 遵循的协议类型与所述用户参数的对应关系。
具体的, 如果查到所述目的网元, 则确认所述用户为 3G用户, 通过 Diameter信用控制 DCC协议直接触发在线计费系统 OCS进行实时计费; 如 果没查到所述目的网元, 则确认所述用户为 2G用户, 通过所述用户在 HLR 上的签约信息触发到所述用户归属地的 OCG上进行实时计费。
通过采用本发明实施例提供的路由的方法, 可以实现发起端的网元到目 的网元的映射, 便于选择何种协议和触发方式实现实时计费流程。
将上述实施例的路由方法应用于具体实施环境中, 如用户呼叫流程, 如 图 2所示: 对于已经歩入 3G的地方, 按照交换侧设备通过 DCC协议直连在 线计费系统的方案进行建设。 对于还未进行 3G建设的地方, 按照现有的 2G 组网方案, 通过协议转换实体将 CAP信令转换成 DCC协议, 然后再向 OCS 发起计费请求。 对于 2G用户漫游到 3G网络地区的情况, 因为 2G用户的归 属地还没有完成 3G网络的建设, 因此需要交换侧保留原来的路由方式, 触 发到归属地的 OCG实现实时计费流程。
为了实现上述两次触发方式, 在交换侧 MSS ( 3G设备) 上构造一个网 元路由映射表, 结构如表 1所示, 可以根据实际情况进行修改。
表 1 :
Figure imgf000005_0001
配置举例如表 2:
表 2:
Figure imgf000006_0001
对于已经完成 3G建设的地区, 当用户的呼叫路由到 MSS上后, MSS可 OCG的 GT地址, 查询网元路由映射表, 获取目的网元地址、 遵循的协议类 型等, 将 3G地区的用户通过 DCC协议直接触发 OCS进行实时计费; 而对 于 2G用户, 不在表中配置信息, MSS查询路由表失败后, 按照原来的触发 方式, 通过用户在 HLR上的签约信息触发到该用户归属地的 OCG上完成实 时计费流程。 这样就可以实现在不修改现网 HLR数据的情况下, 完成两种 触发方式、 触发协议的选择等。

歩骤 301, MSS1查询映射表, 确定触发方式;

在 3G改造完毕时, 可以考虑删除该表的结构, 以及使用逻辑, 减少不 必要的性能损耗。
本发明实施例中, 通过对 3G设备的改造, 实现从 2G到 3G改造过程实 时计费流程的平滑过渡, 保证 2G和 3G混合组网情况下实时计费的实施。 在 保证平滑过渡的前提下, 尽可能的节约成本, 减少性能消耗, 提高整个系统 的性能。
目前的 GPRS (General Packet Radio Service, 通用无线分组业务) 计费 使用的是离线话单计费方式, 存在较大的欠费风险和损失。 3G时代数据业 务的计费, 更倾向于实时计费方式。 因此, 2G用户漫游到 3G网络后, 同样 存在路由上的难题。
因此, 对于 3G网络中的 GGSN (Gateway GPRS Supporting Node, 网关
GPRS支持节点) 网元, 同样可以新增一个路由映射表, 存放实时计费方式 的路由信息和遵循的标准协议等信息, 将本发明实施例提供的路由方法应用 于 GPRS计费流程中, 如图 4所示。 用户使用数据业务触发计费事件后, GGSN可以根据用户所属号段、 所使用的服务等信息查询路由表, 获取要触 发的网元 IP地址, 以及本次触发需要遵循的协议等信息。 如果没有查询到对 应记录, 则按照原来的离线计费方式进行计费。 如果查询到对应的记录, 则 通过记录中指定的协议触发到对应网元实体完成实时计费功能。
用户示例如图 5所示, 包括以下歩骤:
歩骤 501, GGSN/CCG查询映射表确定计费方式为在线计费;
歩骤 502, GGSN/CCG向 OCS发送 CCR消息 (开始) ; 消息中包含了 申请的分片使用量。
分片指的是对用户一次的使用量做一定粒度的划分。 分片的使用量已经 设定。 用户每次上网之前, 先发送一个分片的使用量请求到计费点。 计费点 会根据用户的余额返回一个授权使用量。 一般余额足够的情况下, 授权使用 量和客户端申请的使用量是相等的。 但是用户余额不够的情况下, 授权使用 量是根据用户的余额和费率反算出来的使用量, 小于申请的使用量。
歩骤 503, OCS对该用户进行鉴权, 预算本次授权使用量需要的金额, 并对这部分金额进行预留。 如果用户余额不够扣除之后, 则根据用户的余额 进行反算出剩余的使用量, 并作为授权使用量, 向 GGSN/CCG返回 CC A消 息 (开始) ;
歩骤 504, GGSN/CCG根据授权使用量允许用户使用并对使用量进行监 督;
歩骤 505, GGSN/CCG 向 OCS 发送 CCR{Update}消息 (更新) ; CCR{Update}消息中包含了上个分片已经使用的使用量信息, 以及下个分片 的请求使用量。
歩骤 506, OCS根据已经使用的使用量信息对该用户进行批价、 入帐, 根据下个分片的请求使用量, 对账户余额进行预算, 并再次预留这部分费 用, 向 GGSN/CCG返回 CCA消息 (更新) ; 其中, 歩骤 505和歩骤 506的 更新消息可以重复多次;
歩骤 507, 用户停止使用;
歩骤 508, GGSN/CCG向 OCS发送 CCR消息 (终止) ; 终止消息中包 含了上个分片的使用信息。
歩骤 509, OCS对该用户进行批价、 入帐, 向 GGSN/CCG返回 CCA消 息 (终止) ;
歩骤 510, GGSN/CCG查询映射表, 确定离线计费方式;

歩骤 513, 帐务从 CG采集话单;
歩骤 514, 帐务将话单传到 OCS进行计费;
歩骤 515, OCS向帐务返回话单。
