本发明涉及通信技术领域， 尤其涉及一种计费系统及方法。
背景技术
随着电信运营商运营水平的不断提高和计费系统的不断发展，电信运营商 对于计费系统的正确性、准确性的要求越来越高。 电信运营商一般要求在每天 00:00点对前一天的用户帐户数据和话单信息进行快照，从计费系统导出 00:00 点之前的前一天的用户帐户数据和话单信息 ,然后帐务系统使用该帐户数据和 话单数据进行核对 , 确保用户帐户余额减少的费用和生成的话单费用保持一 致， 从而验证计费系统费用计算和话单输出的正确性。
在用户使用电信业务过程中， 外部功能实体（如用户管理系统、 网元管理 系统等）和计费系统进行实时交互， 由计费系统对用户的业务服务使用进行实 时预算、批价和扣费，这样的计费系统称为实时计费系统。对于实时计费系统， 计费系统中的用户帐户数据实时变化，而对计费系统中所有帐户数据的快照需 要一定时间 ,在对帐户数据进行快照这段时间，用户有可能又有消费或者充值， 用户帐户数据可能出现变化， 从而导致快照的帐户数据不准确。
另一方面， 电信运营商为了降低用户欠费的风险，一般将持续时间较长的 用户业务服务按时间进行分片， 采用分片计费。 例如， 对于话音呼叫计费， 可 以以呼叫接入网元每 5分钟请求计费一次，计费时间分片就是 5分钟。如果存 在某些用户一次业务服务的过程跨越 00: 00点， 则可能部分时间分片在 00: 00点之前计费， 部分时间分片在 00: 00点之后计费。
现有技术提供一种对实时计费系统的帐户数据进行快照的方法，能够对帐 户数据进行实时镜像。 当实时计费系统正常运行时，帐户数据单元与镜^ 储 单元的数据同时被处理。在对帐户数据进行快照时断开入帐单元与镜像存储单 元的连接，此时入帐单元的入帐处理只对帐户数据单元有效，对镜像存储单元 无效。快照单元对镜像存储单元中的帐户数据进行快照，在快照数据使用完成 后 , 再恢复入帐单元和镜像存储单元之间的实时镜像连接。
发明人在实现本发明的过程中发现使用这种快照方法：计费系统中需要同 时保存两份用户帐户数据， 更新计费系统时必须更新镜像存储单元， 而且要保 证两次更新同时成功或者同时失败。 不但系统存储空间增大了一倍， 而且增加 了系统复杂度； 在每次的用户帐户数据快照完毕后， 必须恢复镜像存储单元的 帐户数据， 否则会出现帐户数据单元与镜 储单元数据不一致，增加了系统 维护的复杂度；同时，如果存在用户使用业务服务跨越帐务平衡稽核的时间点， 会导致帐务平衡统计不正确。

具体实施方式
本发明实施例提出了实时计费系统中的帐户数据快照方法，通过入帐单元 接收入帐请求， 当确定出正在对帐户数据进行快照处理时，将入帐请求中的帐 户信息发送给快照单元； 快照单元导出与帐户信息对应的帐户数据， 并向入帐 单元返回导出完毕通知； 入帐单元对入帐请求进行入帐处理。 并在结合话单拆 分方法的基础上，将帐户快照数据和话单数据进行比较，从而实现实时计费系 统的帐务平衡。
特别的， 本发明实施例设置两个参数： 快照时间点参数和快照状态参数。 其中，快照时间点参数是预先设定的参数，在系统时间到达快照时间点的时候， 快照单元启动对帐户数据的快照处理，快照得到的就是实时计费系统在快照时 间点的帐户数据。 快照时间点可以根据需要进行调整。
快照状态参数根据系统的快照状态设定，包括两个特征值： "未快照"和"快 照中"。 "未快照"表示快照单元未对帐户数据进行快照处理， "快照中"表示快 照单元正在对帐户数据进行快照处理。快照状态参数可以由快照单元根据快照 进行状态设定，也可以由其它功能单元根据快照单元的快照进行状态设定。 当 前时间到达预先设定的快照时间点时， 快照单元启动对所述帐户数据快照处 理， 并将快照状态参数设定为"快照中"； 在快照单元对帐户数据快照处理结束 后， 将快照状态参数设定为"未快照"。
下面结合各个附图对本发明实施例技术方案的主要实现原理、具体实施方 式及其对应能够达到的有益效果进行伴细的阐述。
如图 1所示，为本发明实施例提出的帐户数据快照方法的主要实现原理流 程图， 其中， 步骤 11 , 入帐单元接收外部功能实体的入帐请求。
特别的， 外部功能实体可以是如用户管理系统、 网元管理系统等与实时计 费系统进行交互的功能实体。
步骤 12, 入帐单元才 据快照状态参数的特征值判断当前的快照状态， 如 果当前的快照状态参数的特征值为 "未快照"， 则直接执行步骤 14， 如果当前 的快照状态参数的特征值为 "快照中"， 则执行步骤 13。
特别的，快照状态参数由快照单元或其它功能单元设定，入帐单元在入帐 处理之前提取快照状态参数的特征值， 进行相关判定。
步骤 13、 入帐单元将入帐请求中的帐户信息发送给快照单元， 快照单元 接收到该帐户信息后，优先导出该帐户信息对应的帐户数据， 并向入帐单元返 回导出完毕通知。
特别的，快照单元接收到该帐户信息后， 判断该帐户信息对应的帐户数据 是否已经导出， 如果是， 向入帐单元发送导出完毕通知， 通知入帐单元可以进 行入帐处理； 否则， 优先导出该帐户信息对应的帐户数据， 并向入帐单元发送 导出完毕通知， 通知入帐单元可以进行入帐处理。
相应的，快照单元在启动快照处理后，将快照状态参数的特征值设定为"快 照中"状态， 在所有帐户数据导出为快照数据后， 将快照状态参数的特征值设 定为"未快照"状态。
步骤 14, 入帐单元对该入帐请求进行入帐处理。
上述实施例为本发明实施例提出的帐户数据快照方法，基于上述的帐户数 据快照方法，本发明实施例提供一种实现帐务平衡的方法，如图 2所示，其中， 步骤 21、 根据上述实施例提供的帐户数据快照方法， 得到帐户数据的快 照数据。
步骤 22、根据预先设定的快照时间点，将跨越快照时间点的话单拆分为两 张话单，记为第一话单和第二话单。将快照时间点之前产生的第一话单写入快 照时间点之前的话单数据 ,将快照时间点之后产生的第二话单写入快照时间点 之后的话单数据。
如前所述， 电信运营商为了降低欠费风险，将持续时间较长的用户业务服 务按时间进行分片， 按时间分片进行入帐处理。 然而， 对于持续时间较长的用 户业务话单却并不进行任何处理，较长时间的话单只写为一张话单。 由于有些 较长的话单跨越系统快照时间点， 为了实现帐务平衡，就必须对这些话单进行 拆分。
话单拆分的方法还可以是根据预先设定的时间分片，以快照时间点之前最 后一个时间分片点为界，将跨越快照时间点的话单拆分为两张话单，记为第一 话单和第二话单，将快照时间点之前产生的第一话单写入快照时间点之前的话 单数据； 将快照时间点之后产生的第二话单写入快照时间点之后的话单数据。
特别的，预先设定的时间分片是一个系统设定值， 由系统根据实际需要预 先设定， 并可以根据需要调整。 时间分片的设定长度与实时计费系统计费时间 分片的设定长度相同， 均是由系统统一设定。
如图 3 所示， 为一种话单拆分方法的示意图， 其中， 用户的一次通话从 23: 40持续到 00: 05， 系统快照时间点为 00: 00， 每个时间分片为 15分钟， 23: 55为一个时间分片点。
在通话结束后， 话单处理单元以快照时间点 00: 00之前的最后一个时间 分片点 23: 55为界， 将本次通话的话单拆分为两张话单， 23: 40 ~ 23： 55为 第一个时间分片产生的话单， 由于该话单产生于快照时间点之前， 因而写入快 照时间点之前（前一天） 的话单数据中， 23: 56 - 00: 05 产生的话单， 由于 其产生于快照时间点之后， 因而写入快照时间点之后 (后一天）的话单数据中。
特别的 ,由于现有技术中以通话结束时间作为话单的产生时间，也就是说， 在通话结束的时候进行写话单处理。 因而本实施例中， 当话单以时间分片被拆 分时， 将每个时间分片产生的话单的结束时间作为话单的时间分片点。 因此， 虽然 23: 56 - 00: 00之间通话的通话时间在 00: 00之前， 但由于 23: 56 ~ 00: 00之间通话的通话时间包含在 23: 56 - 00: 05的通话时间分片中， 因而 被分为同一张话单， 其话单的产生时间就为 00: 05， 所以， 这张话单写入快 照时间点之后 （后一天） 的话单数据中。
特别的， 本实施例中， 话单拆分的时间精确度都是精确到分钟， 实际应用 系统中 , 一般会将话单拆分的时间精确度精确到秒钟。
本实施例中仅示意出快照时间点之前仅有一个时间分片点的情况， 实际 上，快照时间点之前可能有多个时间分片点， 同样以快照时间点之前的最后一 个时间分片点为界，将快照时间点之前的最后一个时间分片点之前的话单记为 一张话单。 快照时间点之后如果存在多个时间分片点， 也同样记为一张话单。
步骤 23、 比较快照数据和快照时间点之前的话单数据， 实现帐务平衡。 采用本发明实施例提供的方案 , 在保证实时计费系统完全实时的前提下 , 解决实时计费系统由于帐户数据和 /或话单不精确而无法做到真正帐务平衡的 问题。
