图 2是根据本发明实施例的信令互通网关的结构框图; 图 3是根据本发明实施例的信令互通网关的优选结构框图一; 图 4是根据本发明实施例的信令互通网关的优选结构框图二; 图 5是根据本发明实施例 1的短信状态报告方法的具体流程图; 图 6是才艮据本发明实施例 1的 Hub内部数据结构的示意图; 图 7是根据本发明实施例 3的短信状态报告方法的详细流程图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互组合。 图 1是根据本发明实施例的短信状态报告方法的流程图, 包括: 步骤 S 102 , 信令互通网关(以下简称 Hub )接收源网络中的 SMSC发送 的状态 4艮告信令, 并转发到目的网络中的 HLR; 步骤 S 104, Hub接收来自该 HLR的状态报告响应, 存储状态报告信令 中的第一目的用户号码和状态 ^艮告响应中的第二目的用户号码之间的对应关 系; 步骤 S 106, Hub接收来自该 HLR的通知信令; 步骤 S 108, Hub将通知信令中的用户号码作为第二目的用户号码, 根据 对应关系查找对应的第一目的用户号码, 将通知信令中的用户号码替换成查 找到的第一目的用户号码, 并发送至 SMSC。 相关技术中, 不同网络之间支持的 MAP版本可能不同, MAPvl不支持 一机多号, 而 MAPv2或以上能够支持一机多号, 此时, HLR中, 对于同一 个终端, 仅釆用一个号码作为标识, 若源网络中的 SMSC发送的状态报告信 令中的号码不是该用作标识的号码, 则无法辨识来自 HLR 的包含用作标识 的号码的信令, 从而可能导致处理混乱, 即无法实现漫游状态下的短信状态 报告机制。 本发明实施例提供的方法中, 通过在漫游通知流程中引入信令互 通网关, 存储状态报告信令中的目的用户号码和状态报告响应中的目的用户 号码的对应关系, 在转发通知信令之前, 使用存储的状态 4艮告信令中的目的 用户号码替换通知信令中的目的用户号码, 解决了相关技术中由于网络间釆 用的 MAP版本不同导致短信状态通知机制无法实现的问题, 在不改变运营 商已有网络架构的基础上, 实现了不同 MAP版本状态报告机制的兼容处理, 从而实现了漫游条件下的短信通知机制。 优选地, 在步骤 S 104之后, 还包括: 若源网络中的 SMSC支持 MAPvl , 则 Hub删除状态报告响应中的第二目的用户号码;若源网络中的 SMSC支持 MAPv2或以上, 则 Hub将状态 4艮告响应中的第二目的用户号码替换成状态 艮告信令中的第一目的用户号码; Hub将状态 4艮告响应发送至 SMSC。 通过 该过程, 能够进一步地实现状态报告响应的发送, 且可以兼顾 SMSC中的各 MAP版本, 普适性较强。 优选地, Hub还可以将状态报告响应中的 SMSC号码替换成源网络中的 SMSC的号码。 从而保证交互的状态报告响应信令中的数据的正确性, 方便 后续的鉴权处理。 优选地, Hub还可以存储源网络中的 SMSC的号码和状态报告响应中的 第二目的用户号码之间的对应关系, Hub还可以根据该对应关系查找通知信 令中的用户号码对应的 SMSC的号码,并将通知信令中的 SMSC号码替换成 查找到的 SMSC的号码。 从而保证交互的通知信令中的数据的正确性, 方便 后续的鉴权处理。 优选地, 步骤 S 102包括: Hub接收源网络中的 SMSC发送的状态报告 信令; Hub在本地 HLR路由表中, 查找状态报告信令中的目的用户号码对应 的目的网络中的 HLR; Hub将状态报告信令转发到该 HLR。 通过在 Hub中 设置本地 HLR路由表, 为状态报告信令的转发提供了依据, 釆用本地的路 由表进行查找, 提高了 Hub的处理效率。 优选地, 在步骤 S 108之后, 还包括: Hub删除对应关系。 由于已完成 通知信令的发送, 不再需要查找对应关系, 因此, 可以将对应关系删除, 从 而节约 Hub的存储空间, 提高 Hub的运行效率。 优选地, 在步骤 S 108之后, 还包括: 源网络中的 SMSC查找以通知信 令中的第一目的用户号码作为被叫用户的短信; 将短信发送到通知信令中的 第一目的用户号码。 通过该过程, 完成了 SMSC根据通知信令来重发用户为 发送的短信的过程, 无需反复重试, 从而节约了 SMSC的处理资源。 优选地, 将短信发送到通知信令中的第一目的用户号码包括: 源网络中 的 SMSC将短信通过 MT信令发送到 Hub, Hub向目的网络中的 HLR查询 路由,并根据路由将短信转发至第一目的用户号码;或者,源网络中的 SMSC 向源网络中的 HLR查询路由, 并根据路由将短信发送至第一目的用户号码。 以上的第一种方法, 由 Hub进行短信的转发, 无需 SMSC查找路由, 简 化了 SMSC的处理过程; 第二种方法, 由 SMSC向 HLR查询路由后发送, 减轻了 Hub的处理负荷。 优选地, 其特征在于, 以上的 Hub可以为多个 Hub的级联。 通过对 Hub 的级联, 能够适应源网络到目的网络之间需通过一个或多个网络的情况, 能 够适应各种网络拓 4卜情况。 图 2是根据本发明实施例的信令互通网关的结构框图, 该信令互通网关 包括: 第一接收模块 20 , 用于接收源网络中的短信中心 SMSC发送的状态报 告信令;
