而随着短消息业务的幵展与移动用户的普及,短消息的流量也日益增长, 这对短消息系统的容灾备份和高可靠性也提出了更高的要求, 需要短消息系 统能够具有自适应能力, 依据当前系统运行状况做出反应, 尽可能持续稳定 地提供短消息服务。
鉴于上述情况,为使短消息组网中的各套短消息系统能够互有备份关系, 以弥补单套系统容灾能力不足的问题, 从而提高短消息服务的可靠性, 公开 号为 CN 1453979A的中国专利申请提供了一种可行的技术方案。
图 1为该专利申请提供的一种短消息组网的结构图。 由图 1可以看出, 该组网包括 3 套短消息系统, 即 GIW1+SMSC1 , GIW2+SMSC2和 GIW3+ SMSC3, 将其中的第 1、 2两套短消息系统建立连接, 使得这两套系统存在备 份关系。 则如果 GIW1故障, STP可将原本发给 GIW1的消息发给 GIW2, 而如果预定的 SMSC2故障, GIW2可以将消息发给 SMSC1处理, 以维持短 消息业务的持续服务。 该专利申请所提出的技术方案可以实现短消息系统的信令级容灾和系统 级容灾。 以提交短消息为例, 简单地说, 短消息流程为 ->STP->GIW->SMSC, 则如果 STP检测到某套短消息系统的 GIW故障, 则利用 STP的全局码地址 变换功能, 将消息分流至备份短消息系统的 GIW上, 从而实现信令级容灾。 另一个就是系统级容灾, 比如, 图 1中的 SMSC2为 SMSC1的备份 SMSC, 而 GIW1检测到 SMSC1故障, 则 GIW1可以将消息分流至 SMSC2上。 下发 短消息的流程为- >SMSC->GIW->STP, 基于下发短消息的信令级容灾和系统 级容灾的处理同提交短消息流程中的处理类似, 因此不再赘述。
但上述处理方案的缺点在于:对 GIW/SMSC中短消息的分流处理过于简 单。 具体分析如下:
在分流短消息至其它 GIW/SMSC时, 只能完全均分全部消息流量, 而没 有考虑这些 GIW/SMSC当前运行的负荷支撑情况。 比如, 图 1中, GIW2分 流消息给 SMSC1时, 并未考虑 SMSC1的负荷情况。 且由于 GIW2未与组网 中的 SMSC3连接, 不能利用组网中的 SMSC3的可用处理能力, 因此 GIW2 在分流时不能在组网中的各个 SMSC之间进行流量调节分配。并且即使 GIW2 和 SMSC3 也有连接, 可以将短消息分给 SMSC3 , 但如何权衡 SMSC1 和 SMSC3的流量分配, 又如何考虑 GIW3对 SMSC3的流量影响等等, 该方案 都没有提及。
所以说, 现有技术中的短消息系统只是从冗余角度通过建立备份关系达 到容灾的目的, 且只能使用所建立的备份短消息系统进行冗余备份, 而不能 根据当前组网中各个短消息系统的实际运行负荷做出流量调节。 并且现有技 术中转移消息至备份系统是全部转移, 而不考虑备份系统的当前负荷, 在实 现容灾的同时, 也增大了冲击备份系统的几率。 发明内容

图 1为现有技术中的短消息系统结构图;
图 2为本发明提供的一种分流短消息系统的结构图;
图 3为本发明在图 2所示系统基础上设置局间 FCC后的结构示意图; 图 4为本发明提供的 FCC的内部结构示意图。 具体实施方式
本发明的主要核心在于: 在现有的短消息组网中增加一个 FCC, 将该组 网称为分流短消息系统, 分流短消息系统中各个短消息系统中的模块, 即 SMSC和 GIW, 均与 FCC连接。 当分流短消息系统中的某个 SMSC故障时, 则与该 SMSC对应的 GIW将原本发送至该 SMSC的消息汇集至 FCC; 类似 地, 当某个 GIW 出于某种原因也不能接收短消息时, 则与该 GIW对应的 SMSC也可以将原本发送至该 GIW的消息汇集至 FCC。FCC则确定所收到的 短消息的分流路径, 并将该短消息通过所确定的分流路径进行分流转发。
另外, 上述分流短消息系统中, 各个短消息系统中的 SMSC还可以与其 它短消息系统中的 GIW连接, 类似地, GIW也可以与其它短消息系统中的 SMSC连接, 针对这种连接关系, FCC在需要转发消息时, 同样是确定分流 路径, 并进行消息的分流转发。
对于上述两种组网情况来说,虽然 GIW与 SMSC之间的连接关系有些不 同, 但 FCC确定转发路径及进行消息转发的处理相同。
采用本发明的分流短消息的方法, 主要可以实现两方面的功能: 1、 冗余 路径功能,该功能主要通过 FCC为当前需要转发的短消息选择分流路径实现; 2、 智能分流功能, 该功能主要通过 FCC根据当前分流短消息系统中各个模 块的负荷情况在所选择的分流路径中对短消息进行分流转发实现。
为更好地理解本发明, 现结合附图及实施例对本发明作进一步描述。 图 2所示为本发明分流短消息系统的一种结构图, 该分流短消息系统包 含四套短消息系统, 每套短消息系统中包括两个模块, 即 SMSC和 GIW, 这 四套短消息系统分别为 SMSC1+GIW1、 SMSC2+GIW2, SMSC3+GIW3 和 SMSC4+GIW4, 其中, 每套短消息系统内的 SMSC与 GIW必须连接。 短消 息系统内的 SMSC还可以与其它短消息系统中的 GIW连接, 类似地, GIW 可以与其它短消息系统中的 SMSC连接。如图 2所示, GIW2分别与 SMSC1、 SMSC2和 SMSC3连接, SMSC1与 GIW1和 GIW2连接。 同时, 本发明的分 流短消息系统还包括一个 FCC,该 FCC与本分流短消息系统内的所有 SMSC 和 GIW连接。 在转发短消息时, SMSC可以将 FCC当作 GIW, 并向其转发 短消息, 类似地, GIW可以将 FCC当作 SMSC, 并向其转发短消息, 实质上 FCC只是个转发点。
由于 FCC对 SMSC和 GIW中短消息的分流处理相同,因此下面仅以 FCC 对图 2中 GIW1的短消息进行分流处理为例。
1、 冗余路径功能的实现:
如图 2所示, 所有短消息系统中的 SMSC、 GIW均连接至 FCC, 则上行 短消息提交路径在原本的- >STP->GIW->SMSC的基础上, 还可以增加如下的 冗余路径: ->STP->GIW->FCC -〉 SMSC; 类似地, 下行短消息发送路径在原 本的- >SMSC-> GIW->STP 的基础上, 还可以增加如下的冗余路径: ->SMSC->FCC-> GIW-STPo
以 GIW1上行发送短消息为例, 在正常情况下, 假设该 GIW1上行发送 的短消息通过路径- >STP->GIW1->SMSC1发送, 也即 GIW1直接将短消息发 送到该路径的对端模块, 即 SMSC1 , 如果此时该 SMSC1 由于各种原因而不 能处理短消息, 这时该上行短消息则可以通过冗余路径进行发送, 比如, 选 择冗余路径- >STP->GIW1 ->FCC->SMSC2、 ->STP->GIW1->FCC->SMSC3或 者- >STP- >GIWl->FCC-> SMSC4, 当然也可以同时通过这三条冗余路径中的 任意两条或三条进行发送。 也就是说, GIW1 会首先将短消息转送到 FCC, 然后再由 FCC选择该短消息的分流路径, 该分流路径应为该 FCC到组网中 除 SMSC1之外的其它 SMSC的路径, 如前所述, 该路径可能是一条, 也可 能是多条, 因为 FCC可以只选择其它 SMSC中的一个, 也可能选择多个, 或 者选择除 SMSC1之外的其它所有 SMSC:。 之后该 FCC即可将该短消息通过 所选择的分流路径发送到 SMSC1之外的其它 SMSC。
其中, 对于分流短消息系统, 各个模块触发分流的因素大致可以归纳为 如下几种:
a、 GIW与 SMSC间的连接中断;
b、 SMSC示忙, 即指示负荷过重;
c、 GIW示忙, 即指示负荷过重。
因此,如果 GIW与某 SMSC的连接中断,则 GIW将原本发送给该 SMSC 的消息发送给 FCC, 由 FCC进行分流转发; 类似地, 如果 SMSC与某 GIW 的连接中断, 则 SMSC将原本发送给该 GIW的消息发送给 FCC, 由 FCC进 行分流转发。
而如果某 SMSC示忙,则所有连接该 SMSC的 GIW将消息均发送给 FCC, 由 FCC进行分流转发;类似地,如果某 GIW示忙,则所有连接该 GIW的 SMSC 将短消息均发送给 FCC, 由 FCC进行分流转发。
另外, 如前所述, FCC在接收到短消息后, 需要确定针对该短消息的分 流路径, 之后再通过该分流路径对该短消息进行分流转发。 为方便 FCC确定 短消息的分流路径, 还可以为分流短消息系统中与 FCC连接的每一个模块分 别设置唯一的标识。分流短消息系统中的任一模块在向 FCC转发需要分流的 短消息时, 将该短消息的原目的地的标识信息设置在该短消息中。 FCC在选 择分流路径时, 就可以根据该标识确定对应模块的类型, 并根据所述标识确 定组网中与该标识对应模块的类型相同的其它模块, 之后即可通过从所确定 的其它模块中选择一个或多个模块来确定分流路径。 其中, 为保证针对每个 模块的标识的唯一和正确性, 还可以由 FCC在各个模块与本 FCC连接时对 该模块的标识进行校验。
另外, 目前可以将需要转发的短消息分成三类: 群发消息、 不可变更目 的地的消息和可变更目的地的消息,因此,分流短消息系统中的 GIW和 SMSC 可以指示自身发送给 FCC的短消息的消息类型, 具体来说, 可以是通过该短 消息将该短消息的消息类型发送给 FCC。 下面以 GIW1在无法将短消息发送 给 SMSC1时需要向 FCC转发短消息为例,来说明 FCC针对这三类短消息的 分流路径设置方案。
如果 GIW1指示转发给 FCC的短消息为可变更目的地的消息, 则 FCC 可以将本 FCC到分流短消息系统中除 SMSC1之外的任意一个或任意几个其 它 SMSC的路径作为分流路径, 也可以将本 FCC到 SMSC1之外的其它所有 SMSC的路径作为分流路径;
如果 GIW1指示转发给 FCC的短消息为群发消息, 则 FCC在转发消息 时, 直接将本 FCC到除 SMSC1之外的所有 SMSC的路径作为分流路径; 如果 GIW1指示转发给 FCC的短消息为不可变更目的地的消息,这种情 况下,则需要 GIW1提供该不可变更目的地的模块的相关信息,即特定 SMSC 的相关信息, 则 FCC 需要将该短消息转发给该特定 SMSC, 即将到该特定 SMSC的路径作为分流路径。
上述冗余路径功能提供了 FCC选择分流路径的方案。对于可变更目的地 的短消息来说, 还可以通过 GIW1设置短消息的处理模式, FCC根据短消息 的处理模式对该短消息进行处理。
比如, 如果 GIW1指示本短消息的类型为可变更目的地, 则 GIW1还可 以通过该短消息将针对该短消息的处理模式发送给 FCC, 该处理模式可以包 括指定目的地模式和未指定目的地模式两种, 且如果 GIW1在本 GIW1确定 处理模式为指定目的地模式时, 应该在该短消息中携带所指定的目的地模块 的相关信息。 这种情况下, FCC从选择一个或多个 SMSC之前, 需要先判断 短消息中是否携带了针对该短消息的处理模式, 如果携带的是未指定目的地 模式, 则直接执行选择一个或多个 SMSC; 如果携带的是指定目的地模式, 则获取对应的目的地模块, 即某个 SMSC, 的相关信息, 并判断该 SMSC是 否可分流, 如果不可分流, 则 FCC选择一个或多个 SMSC; 如果可分流, 则 优先选择该 SMSC, 并在该 SMSC不能分流所述短消息的所有流量时, 再选 择一个或多个 SMSC对该短消息进行分流。
FCC还可以根据分流短消息系统中各个模块的运行情况和负荷情况, 来 确定在之前所确定的各个分流路径中进行分流转发的具体实现方案的, 该具 体实现方案则由下面的智能分流功能。
2、 智能分流功能的实现- 整个系统中所有与 FCC连接的 SMSC和 GIW均需定时向 FCC上报自身 的运行信息。 当然, 在所有模块都正常运行的情况下, SMSC和 GIW只是上 报自身的运行信息, 短消息还是按照正常的路径传送, 并不用发送到 FCC。 当需要分流时, SMSC和 GIW将需要分流处理的短消息发送到 FCC,如果该 消息为可变更目的地的消息, 则 FCC可以通过 SMSC和 GIW定时上报的运 行信息进行分析判断, 在已确定的分流路径中确定最合理最有效的分流转发 方式, 并进行分流转发。
该处理首先通过分析确定 SMSC和 GIW上报给 FCC的运行信息, 该运 行信息可以包括负荷信息和运行情况信息。 对于 SMSC来说, 其功能主要在 于短消息的存储调度, 其负荷状态不只与负载量有关, 比如, 在短消息下发 失败时需要存储该消息以等待下次调度, 这也是造成 SMSC负荷的一部分, 所以仅依据剩余负载量不足以概括其负荷信息。 而对于 GIW, 当前剩余负载 量可以直接反映出其负荷信息, 但其独有特点则在于可以检测至 STP的信令 链路是否可用,如果链路故障,则代表该 GIW当前无法处理消息。所以, SMSC 的运行信息可以包括: 最大负载消息量、 当前剩余负载量及当前可用状态, 该可用状态即为 SMSC的忙闲状态; GIW的运行信息可以包括: 最大负载消 息量、 当前剩余负载量及当前可用状态。
如果组网中的各个模块向 FCC上报自身的运行信息中包括当前可用状 态, 则 FCC在选择一个或多个模块时, 可以根据各个模块的可用状态进行选 择, 具体来说, FCC需要获取所述其它模块中各个模块的运行信息, 并判断 各个模块的当前可用状态是否为可用, 如果是, 则选择该模块; 否则, 不选 择该模块。且 FCC如果在一段时间内'没有收到某个模块当前可用状态的信息, 则可以 FCC可以认为该模块当前的可用状态为不可用。
另外, 对于 FCC来说, 则在收到某个模块发送来的短消息时, 如果确定 该短消息为可变更目的地的消息, 且 FCC选择了多个用于转发该短消息的模 块, 则可以根据 FCC所选择的这些模块的运行信息确定分配给这些模块的短 消息流量, 之后再根据所确定的短消息流量进行分流转发。
如果各个模块上报的运行信息包括最大负载量和当前剩余负载量, 则 FCC可以统计当前可分流的各个 SMSC的剩余处理能力之和,即∑剩余能力, 该剩余处理能力之和即为各个 SMSC的当前剩余负载量之和, 并统计这些模 块需要分流处理的短消息流量之和。 之后对这两个计算结果进行判断。
如果∑剩余能力大于或等于短消息流量之和, 则按比例计算出分流至各 个 SMSC的流量, 比如, 可以将短消息均分至各个 SMSC, 也可以按照各个 SMSC的处理能力大小的比例计算分流至各个 SMSC的流量, 然后再进行流 量转发。
如果∑剩余能力小于短消息流量之和, 则先以各个 SMSC的剩余能力为 基准, 即将与该∑剩余能力大小相同的短消息流量分配到各个 SMSC中, 该 分配可以是按比例计算, 比如可以按均分计算, 得出分流至各个 SMSC的流 量, 也可以按照各个 SMSC的剩余处理能力进行分配。 这次分配之后还有剩 余的短消息流量, 针对该剩余流量, 可以依据所有可分流的 SMSC的最大处 理能力, 按比例计算出分流至各个 SMSC的剩余流量, 当然该分配也可以是 均分。
另外, 如前所述, 对于发送消息类型为可变更目的地的短消息给 FCC的 GIW1 来说, 其还可以根据需要指定该短消息的具体处理模式, 比如, 可以 指定该短消息的处理模式为指定目的地模式, 或者为未指定目的地模式。 如果是指定该短消息的处理模式为未指定目的地模式, 则 FCC可以直接 按照上述分配方案进行。 如果指定该短消息的处理模式为指定目的地模式, 则 FCC可以执行以下处理:
FCC获取所指定的目的地模块的相关信息, 比如标识之类的信息, 并判 断该目的地模块是否可分流, 如果不可分流, 则还需采用上述处理; 如果可 分流, 则优先将短消息发送给该目的地模块。 其中, 优先将短消息发送给目 的地模块的处理具体可以包括: 获取该目的地模块的当前剩余处理能力, 即 当前剩余负载量, 如果该剩余处理能力能满足当前短消息的转发, 则将当前 的短消息直接转发给该目的地模块, 如果不能满足, 则按照该剩余处理能力 转发短消息, 并将剩余的短消息按照之前的上述处理方案进行分流转发。
另外, 上述 FCC是在一个组网中设置, 以解决该组网中短消息的分流转 发。 将组网称为局, 因此每个局即对应本发明的分流短消息系统, 且每个局 中通常有多个短消息系统。 在某些情况下, 还可能出现某个局内的所有短消 息系统当前不能完成本局内的短消息分流转发的问题。 针对这种情况, 还可 以再设置一个局间 FCC, 该局间 FCC与多个局中的 FCC, 即局内 FCC连接, 该连接关系如图 3所示。且每个局内 FCC将本局内的各个短消息系统中各个 模块的运行信息发送给局间 FC (。这样, 如果某个局内 FCC确定本局内无法 实现本局的短消息分流转发,则可以将该短消息转发给局间 FCC,由局间 FCC 选择其它的某个局进行分流转发。 比如, 该局间 FCC可以根据各个局内 FCC 上报的运行信息确定某个局比较空闲, 因此可以将收到的短消息转发给该局 的局内 FCC, 由该局内 FCC再对该短消息进行分流转发, 其中, 收到该短消 息的局内 FCC所执行的分流转发处理即为前面所描述的组网中 FCC的处理。
由以上描述可以看出, 本发明方案所提供的分流短消息系统包括 FCC。 短消息系统中的各个模块在短消息路径的对端模块不能接收短消息时, 将该 短消息发送给 FCC, 并接收 FCC转发来的短消息, 其中, 如果需要转发短消 息给 FCC的模块是 GIW,则该短消息路径为短消息提交路径,如果是 SMSC, 则该短消息路径为短消息发送路径。该 FCC主要用于接收分流短消息系统中 各个模块转发来的短消息, 之后确定短消息的分流路径, 并将该短消息通过 所确定的分流路径进行分流转发。
具体来说, 该 FCC可以由两个装置组成, 这两个装置分别为通信装置和 分流装置, 由这两个装置实现上述的分流处理。
其中, 通信装置用于与分流短消息系统中的各个模块通信, 即与分流短 消息系统中的 SMSC和 GIW进行通信,比如,接收各个模块转发来的短消息, 之后将该短消息发送给分流装置, 以及接收分流装置确定的分流路径, 并将 所述短消息通过该分流路径进行转发。
分流装置则用于接收通信装置发送来的短消息, 确定该短消息的分流路 径, 并将所确定的分流路径发送给通信装置。 该分流装置确定短消息的分流 路径的各种具体实现即如前所述, 在此不再赘述。
通过这两个装置即可实现 FCC对短消息的分流转发。
另外, 分流短消息系统中诸如 SMSC和 GIW之类的模块还可能向 FCC 上报本模块的运行信息。 这种情况下, 可以在 FCC中增加设置一个状态检测 装置, 增加状态检测装置后的 FCC如图 4所示。 相应地, 需要通信装置接收 SMSC和 GIW的运行信息, 并将该运行信息发送给状态检测装置。 该状态检 测装置则用于检测 SMSC和 GIW的运行信息,并根据模块的运行信息确定该 模块当前是否可以分流,然后将各个模块是否可分流的信息发送给分流装置。 分流装置则可以根据各个模块是否可分流来确定短消息的分流路径。
对于状态检测装置来说, 该装置还可以在设定时间没有收到某个模块的 运行信息后, 认为该模块当前不可以分流, 之后即将该模块不可分流的信息 发送给分流装置。
以上所述仅为本发明的常见实施方案, 并不用以限制本发明, 凡在本发 明的精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本发 明的保护范围之内。
