步骤 sl01、 通过 IMS注册流程, UE注册到 S-CSCF (服务呼叫 会话控制功能)。 为了简便起见, 这里没有标出 I-CSCF (互通边界媒 体网关功能)和 P-CSCF (代理服务呼叫会话控制功能)。
步骤 sl02、 UE使用合适的 SIP方法发送即时消息到 S-CSCF。 步骤 sl03、 S-CSCF基于 iFC ( initial Filtering Criteria, 初始过滤 规则 )转发即时消息到 IP消息网关。
步骤 sl04、 IP消息网关通过检查 SIP头部、 运营商策略或即时 消息能否在被叫 IMS路由等信息决定是否需要进行服务层面的互通, 如果决定进行服务层面的互通, IP消息网关对该业务进行授权。如果 授权失败, IP消息网关返回失败 ^艮告到 UE; 否则 IP消息网关把即时 消息转换成传统的短消息, 并把短消息路由到传统网络的路由实体。 如果即时消息的长度大于一条短消息的长度, IP消息网关把即时消息 拆分成多条, 并分别把它们转换成短消息格式, 把转换的短消息转发 到短消息服务中心。
步骤 sl05、如果授权成功, IP消息网关发送成功响应到 S-CSCF。 步骤 sl06、 S-CSCF转发成功响应给 UE。
步骤 sl07、 SMS-IWMSC ( Short Message Service-InterWorking Mobile Switching Center,短消息互通移动交换中心)把短消息转发到 短消息服务中心。
步骤 sl08、 短消息服务中心返回报告到 SMS-IWMSC。
步骤 sl09、 SMS-IWMSC转发报告到 IP消息网关。
步骤 sll0、 IP消息网关把接收到的报告转换成合适的 IMS消息 格式, 并转发到 S-CSCF。 如果 IP消息网关在步骤 sl04生成了多条 SM消息, IP消息网关需要等待最后一条报告返回, 并把所有的报告 转换成合适的 IMS消息格式, 把它转发到 S-CSCF。
步骤 slll、 S-CSCF发送转换后的即时消息到 UE。
步骤 sll2、 UE发送成功响应到 S-CSCF。
步骤 sll3、 S-CSCF转发成功响应到 IP消息网关。
在实现本发明的过程中, 发明人发现现有技术至少存在以下问 题: 在现有技术的 IMS-MO 流程中, 主叫 UE 的 SIP 消息通过 IP-SM-GW ( IP消息网关)后转变成 SM消息, 为了保证和现有短消 息流程兼容,转化后的 SM消息应能够根据现有的 MT流程传给对端 UE。 但实际上, 在进行服务层面的互通时, IP-SM-GW根据接收到 的 SIP消息进行消息转换后, 无法进行后续的路由。 而且 CPM消息 和非 CPM消息进行互通的过程中也存在着同样的问题。 发明内容

发明人通过分析发现, 之所以在现有的 IMS-MO 流程中, 主叫 UE的 SIP消息通过 IP-SM-GW后转变成 SM消息后,该转化后的 SM 消息不能根据现有的 MT流程传给对端 UE, 是因为, 在进行服务层 面的互通时, UE发送的为没有封装任何 SM 消息的 SIP 消息 (如 SIMPLE IM或 CPM消息), 因此 IP-SM-GW无法获取 UE的短消息 服务中心地址信息。 因此, 即便能够进行消息转换, 网络侧也不知道 到底要把该转换后的短消息发给哪个短消息中心,消息无法进行后续 的路由。 因此, 提出了以下实施例。
本发明实施例中,一种基于 SIP协议的消息在传统网络中路由的 方法如图 2所示, 包括以下步骤:
步骤 s201、互通服务器接收基于 SIP协议的消息,获取对应的短 消息服务中心地址。
具体的, 该短消息服务中心地址的获取方法可以为:
( 1 ) 互通服务器根据该消息中的用户信息从 HSS ( Home subscriber server, 归属签约用户服务器)上获取与该用户对应的短消 息服务中心地址。
( 2 )互通服务器从该基于 SIP协议的消息中获取对应的短消息 服务中心地址, 这种情况下, 需要在该基于 SIP协议的消息中添加 SM-SC ( Short Message-Service Center, 短信服务中心)地址。
( 3 )互通服务器根据预先从 S-CSCF接收的第三方注册消息中 获取的用户信息与短消息服务中心地址的关联关系, 以及该基于 SIP 协议的消息中的用户信息, 获取与该用户对应的短消息服务中心地 址。
( 4 ) 互通服务器根据本地配置的用户信息与对应的短消息服务 中心地址的对应关系, 以及该基于 SIP协议的消息中的用户信息, 获 取与该用户对应的短消息服务中心地址。
步骤 s202、 互通服务器将该基于 SIP协议的消息转换为短消息, 将获取到的短消息服务中心地址添加在该短消息中并发送。
根据短消息中携带的该短消息服务中心地址,网络侧可以进行短 消息的后续路由处理,从而实现了基于 SIP协议的消息在格式转换后 在传统网络中的路由。
以下结合具体的应用场景,对互通服务器获取短消息服务中心地 址的不同的方式进行详细说明。
本发明的实施例一中, 以获取方式为: 互通服务器从 HSS上获 取短消息服务中心地址为例,说明本发明中一种基于 SIP协议的消息 在传统网络中路由的方法的具体实现方式。
现有技术中, HSS上存储了用户的签约数据和消息路由相关的信 息如短消息服务中心,如果一个运营商的网络中有多个短消息服务中 心,运营商可以通过用户的签约情况为不同的用户分配相应的短消息 服务中心, 并把对应关系保存在 HSS 中。 在现有技术中, 互通服务 器(如 IP消息网关)可以通过 Sh接口从 HSS上下载用户的签约数 据, 为用户提供互通业务; 另外, 互通服务器还可以通过该接口从 HSS上下载消息后续的路由信息(如 MSC/SGSN的地址等)。在本实 施例中, 当互通服务器收到基于 SIP协议的消息时, 判断要进行业务 层面互通业务的处理, 则在该业务授权成功以后, 从 HSS获取该消 息携带的用户信息相关的短消息服务中心的地址。互通服务器可以按 照如下原则获取短消息服务中心的地址:如果互通服务器位于的是主 叫侧的 IMS 网络, 则基于主叫用户的信息 (如地址信息)获取与主 叫相关的短消息服务中心的地址;如果互通服务器位于的是被叫侧的 IMS网络,则基于被叫用户信息获取与被叫相关的短消息服务中心的 地址。 互通服务器把基于 SIP协议的消息转换成传统的短消息后, 将 获取的短消息服务中心的地址添加在转换后的短消息的路由信息中, 以便网络侧进行短消息的后续路由处理。
上述过程的一具体场景如图 3 所示, 以互通服务器在主叫侧的 IMS网络的处理为例, 在短消息业务的网络框架中, 如图 4所示, 包 括 SME ( Short Message Entity, 短消息实体)、 SM-SC、 SMS-GMSC ( Short Message Service Gateway Mobile Switching Center, 短消息移 动交换中心网关) /SMS-IWMSC、 HSS、 CGF ( Charging Gateway Function, 计费网关功能) /CDF ( Charge Distribution Function, 计费 釆集功能 )和 OCS ( Online Charging System, 在线计费系统)。 其中, SM-SC 用于存储短消息; GMSC用于接收到被叫短消息时, 向 HSS 查询路由信息; SMS-IWMSC用于终端发送短消息时进行鉴权等。 网 络中应用的短消息中心, 都是集 SM-SC、 GMSC和 SMS-IWMSC三 个为一体的设备,并没有将这三个功能实体作为单独的物理设备来实 现,所以在下文中,短消息中心即代表 SM-SC、GMSC和 SMS-IWMSC 三个一体的设备。 HSS用于存储用户的数据信息, 包括用户的签约业 务数据和路由信息, CGF/CDF 用于收集并处理用户的离线计费的话 单信息, 然后传递至计费中心, OCS 用于收集并处理用户在线计费 的话单信息, 然后传递至计费中心。 IP消息网关用于实现 IP客户端 与 GMSC/SMS-IWMSC之间的通讯, IP消息网关需进行 IP网络消息 协议和已有 WCDMA/GSM 网络短消息协议 (即 IP 消息网关与 GMSC/SMS-IWMSC之间使用的 MAP协议 )之间传输层面或服务层 面的互通, 即进行基于 SIP协议承载的消息的封装 /解封装或消息格 式的转换。在 3GPP的规范中,提出了基于封装传统短消息格式的 SIP 协议消息和传统的短消息业务在传输层面的互通业务, 以及 SIMPLE IM或 3GPP定义的即时消息和传统的短消息在服务层面上的互通业 务, 其中, IP消息网关作为 IMS域和传统 CS/PS域之间的短消息承 载互通网关,用于进行基于 SIP的消息和传统网络消息互通业务的鉴 权, 消息格式的封装 /解封装或转换和消息的存储转发功能。 该 IP消 息网关通过用户的第三方注册为用户提供服务。在传统短消息业务的 网络框架中,基于 SIP协议的消息的路由如图 3所示,包括以下步骤: 步骤 s301、 通过 IMS注册流程, UE注册到了 S-CSCF上。
步骤 s302、 UE发送 SIP消息到 S-CSCF。
步骤 s303、 S-CSCF基于 iFC转发 SIP消息到互通服务器。
步骤 s304、 互通服务器通过检查 SIP头部、运营商策略或 SIP消 息能否在被叫 IMS路由等信息决定是否需要进行服务层面的互通, 如果决定进行服务层面的互通, 互通服务器对该业务进行授权。 如果 授权失败, 互通服务器返回失败报告到 UE, 对于该失败情况, 与本 发明实施例无关, 在此不做介绍。
步骤 s305 ~ s306、授权成功后,互通服务器向 UE返回成功响应。 步骤 s307、 互通服务器检查到接收到的 SIP 消息为未封装任何
SM消息的消息格式(如 SIMPLE IM/CPM消息 ),根据消息头携带的 主叫用户的信息 (如公共用户标识)从 HSS上获取与主叫相关的短 消息服务中心地址。
步骤 s308 ~ s309、 互通服务器把 SIP消息转换成传统的短消息, 在短消息的地址信息中添加步骤 s507中获取的短消息服务中心地址, 并把短消息路由到传统网络的路由实体 SMS-IWMSC。
步骤 s310、 SMS-IWMSC根据短消息中携带的短消息服务中心地 址信息把该消息转发到短消息服务中心。
步骤 s311、 短消息服务中心返回报告到 SMS-IWMSC。
步骤 s312、 SMS-IWMSC转发报告到互通服务器。
步骤 s313、互通服务器把接收到的报告转换成合适的 SIP消息格 式, 并转发到 S-CSCF。
步骤 s314、 S-CSCF发送转换后的 SIP报告到 UE。
步骤 s315、 UE发送成功响应到 S-CSCF。
步骤 s316、 成功响应被 S-CSCF转发到互通服务器。
以上步骤 s301 ~步骤 s316以互通服务器在主叫侧的 IMS网络的 处理为例, 互通服务器在被叫侧的 IMS 网络的处理与此类似, 在这 里不做重复描述。
本发明的实施例二中, 以获取方式为: 互通服务器从接收的基于
SIP协议的消息中获取短消息服务中心地址为例, 说明本发明中一种 基于 SIP协议的消息在传统网络中路由的方法的具体实现方式。
本实施例中, UE在发送的基于 SIP协议的消息中携带短消息服 务中心的地址, 使得互通服务器在进行消息处理的时候, 把从基于 SIP协议的消息中获取的短消息服务中心地址添加在格式转换后的短 消息中, 从而使该转换后的短消息能够被路由到短消息服务中心。
上述过程的一具体场景如图 5 所示, 以互通服务器在主叫侧的 IMS网络的处理为例, 包括以下步骤:
步骤 s501、 通过 IMS注册流程, UE注册到了 S-CSCF上。
步骤 s502、 UE发送 SIP消息到 S-CSCF, 在 SIP消息中增加短 消息服务中心的地址。
具体的, UE需要发送的 SIP消息中增加短消息服务中心的地址。 由于短消息服务中心地址都会固化保存在 UE的 SIM卡中,因此主叫 UE在发送 SIP 消息的时候,把从 SIM卡里获取的短消息服务中心地 址携带在 SIP消息的消息头或消息体中的参数中(该参数可以为现有 SIP协议的参数, 也可以为扩展的 SIP协议的参数 ), 并通过 IMS核 心网络发送。
步骤 s503、 S-CSCF基于 iFC转发 SIP消息到互通服务器。
步骤 s504、 互通服务器通过检查 SIP头部、运营商策略或 SIP消 息能否在被叫 IMS路由等信息决定是否需要进行服务层面的互通, 如果决定进行服务层面的互通, 互通服务器对该业务进行授权。 如果 授权失败, 互通服务器返回失败报告到 UE, 对于该失败情况, 与本 发明实施例无关, 在此不做介绍。
步骤 s505 ~ s506、授权成功后,互通服务器向 UE返回成功响应。 步骤 s507、 互通服务器检查到接收到的 SIP 消息为未封装任何 SM消息的消息格式(如 SIMPLE IM/CPM消息)。 则互通服务器从 SIP消息中获取短消息服务中心的地址。 步骤 s508 ~ s509、 互通服务器把 SIP消息转换成传统的短消息, 在短消息的地址信息中添加步骤 s507中获取的短消息服务中心地址, 并把短消息路由到传统网络的路由实体 SMS-IWMSC。
步骤 s510〜步骤 s516, 同上述步骤 s310 ~ s316, 在此不做重复 描述。
本发明的实施例三中, 以获取方式为: 互通服务器从 S-CSCF接 收的第三方注册消息中获取短消息服务中心地址为例,说明本发明中 一种基于 SIP协议的消息在传统网络中路由的方法的具体实现方式。
本实施例中, 第三方注册过程中, 应用运营商在 iFC 的参数 ( service info ) 中携带短消息服务中心地址, 通过用户的第三方注册 携带该地址信息到互通服务器,使得互通服务器能够获知用户信息和 短消息服务中心地址的绑定关系,从而在互通业务的后续路由中能够 让格式转换后的短消息被路由到短消息服务中心。
该第三方注册过程的一具体场景如图 6所示, 包括以下步骤: 步骤 s601、 UE建立 IP连接。
步骤 s602、 UE通过 IMS注册流程注册到 S-CSCF。
该步骤中, S-CSCF从 HSS下载的用户签约数据中的 iFC里, 携 带了表示短消息服务中心地址的参数。
步骤 s603、 S-CSCF检查在 IMS注册过程中从 HSS获得的初始 过滤规则。
步骤 s604、 S-CSCF发起第三方注册, 基于初始过滤规则告知互 通服务器用户的注册状态。 在该第三方注册消息中, 携带有 S-CSCF 在步骤 s602中获取的短消息服务中心地址。
步骤 s605、 互通服务器返回成功响应到 S-CSCF。
步骤 s606、互通服务器获取与注册用户相关的短消息服务中心的 地址, 存储短消息服务中心地址与用户信息的关联关系。
步骤 s607、 互通服务器发送注册请求到 HSS。
步骤 s608、 HSS 在需要的时候存储接收到的信息, 用于在消息 等待位被置位的时候通过告警消息告知 UE在 IMS域变为可达。 步骤 s609、 在成功完成注册以后, HSS检查消息等待位是否置 未, 是否需要发起告警流程。
在上述步骤 s601 ~步骤 s609的第三方注册流程后, 互通服务器 获取到了短消息服务中心地址与注册用户的关联关系。 在随后的 IMS-MO流程中, 当互通服务器接收到基于 SIP协议的消息并成功的 进行互通业务的授权以后,可以根据该基于 SIP协议的消息携带的用 户信息(一般来说, 如果互通服务器在主叫网络就使用主叫用户的信 息, 否则使用被叫用户的信息)获取在第三方注册时保存的与该用户 对应的短消息服务中心地址,并将该短消息服务中心地址添加在格式 转换后的短消息中, 以便该消息能够被路由到短消息服务中心。
对于该过程, 与现有技术的 IMS-MO 流程相似, 只是增加了互 通服务器将获取到的短消息服务中心地址添加在格式转换后的短消 息中的步骤, 在此不做重复描述。
本发明的实施例四中, 以获取方式为: 互通服务器根据本地配置 的用户信息与对应的短消息服务中心地址的对应关系获取短消息服 务中心地址为例,说明本发明中一种基于 SIP协议的消息在传统网络 中路由的方法的具体实现方式。
本实施例中,应用运营商在互通服务器上直接配置用户号码段对 应的短消息服务中心的地址信息, 使得互通服务器在进行 IMS-MO 互通业务的时候,能够根据用户信息查到对应的短消息服务中心的地 址,使得格式转换后的短信息能够被路由到短消息服务中心。具体的, 该配置可以为静态配置,运营商可以根据固定的号码段信息配置对应 的短消息服务中心地址, 如 130/133的用户对应短消息服务中心 A, 134/135的用户对应短消息服务中心 B等; 另外, 运营商也可以根据 网络的负载平衡以及在网络出现的故障为用户动态配置为其服务的 短消息服务中心的地址, 这样可以更加合理的利用网络资源, 优化短 信业务的处理。
本实施例增加了在互通服务器上直接配置用户信息与短消息服 务中心地址的对应关系的步骤后 , IMS-MO具体流程和现有技术基本 一致, 不同的是: 当互通服务器接收到基于 SIP协议的消息并成功的 进行互通业务的授权以后, 可以根据该即时消息携带的用户信息(如 果互通服务器在主叫网络就使用主叫用户的信息,否则使用被叫用户 的信息)找到在配置列表中保存的该用户对应的短消息服务中心地 址, 在进行互通业务处理时, 把短消息服务中心地址携带在格式转换 后的短消息中, 以便该消息能够被路由到短消息服务中心。对于该过 程, 在此不做重复描述。
另外,上述各实施例也可以应用于在处理其他的基于 SIP协议的 消息和传统的短消息互通的情况。 例如对于 CPM业务: 当主叫 CPM 用户发送基于 SIP协议的消息到另外一个 CPM用户时, 若该被叫用 户在被叫侧网络不可达, 则根据运营商的策略和用户的偏好, 把该 SIP消息路由到被叫侧的互通服务器, 使用服务层面的互通业务通过 传统域下发该呼叫消息。 另外, 当主叫 CPM用户发送基于 SIP协议 的消息到另外一个非 CPM用户、 但该用户是 IMS签约用户时, SIP 消息被路由到被叫侧的 IMS核心网络, 通过被叫用户的签约信息, IMS核心网络把该 SIP消息路由到被叫侧的互通服务器,使用服务层 面的互通业务通过传统域下发该消息。 在这两种情况下, 都可以通过 上述各实施例提供的方案获取短消息服务中心的地址,使得格式转换 后的短消息能够路由到短消息服务中心。
通过使用以上各实施例提供的方法,由互通服务器获取短消息服 务中心地址并添加在由基于 SIP协议的消息转换后得到的短消息中, 使得格式转换后的短消息能够路由到短消息服务中心, 实现了基于 SIP协议的消息在格式转换后在传统网络中的路由。
本发明的实施例五中, 还提供了一种互通服务器, 用于实现基于
SIP协议的消息在传统网络中的路由。 该互通服务器包括:
短消息服务中心地址获取单元 10, 用于接收基于 SIP协议的消 息, 并获取对应的短消息服务中心地址。
转换单元 20, 用于将该基于 SIP协议的消息转换为短消息。 短消息服务中心地址添加单元 30, 用于将短消息服务中心地址 获取单元 10获取到的短消息服务中心地址添加在转换单元 20转换得 到的短消息中并发送。
进一步的, 如图 7所示, 该互通服务器还可以包括:
收发单元 40, 用于接收基于 SIP协议的消息, 以及发送短消息, 上述的短消息服务中心地址获取单元 10可以根据该收发单元 40接收 到的基于 SIP协议的消息获取该基于 SIP协议的消息相关的终端所对 应的短消息服务中心地址, 上述的短消息服务中心地址添加单元 30 则可以通过该收发单元 40发送本短消息服务中心地址添加单元 30转 换得到的短消息。
其中, 如图 8A所示, 短消息服务中心地址获取单元 10进一步 包括:
第一地址获取子单元 11 , 用于从归属签约服务器 HSS上获取与 该消息中携带的用户信息对应的短消息服务中心的地址。
或者,如图 8B所示,短消息服务中心地址获取单元 10可以进一 步包括:
第二地址获取子单元 12, 用于解析该基于 SIP协议的消息, 获 取该基于 SIP协议的消息中携带的短消息服务中心地址。
或者,如图 8C所示,短消息服务中心地址获取单元 10可以进一 步包括:
关联关系获取子单元 13 , 用于从网络侧接收的第三方注册消息 中, 获取用户信息与短消息服务中心地址的关联关系;
第三地址获取子单元 14, 根据关联关系获取子单元 13获取的用 户信息与短消息服务中心地址的关联关系,以及该消息中携带的用户 信息, 获取与该用户对应的短消息服务中心地址。
或者, 如图 8D所示, 短消息服务中心地址获取单元 10可以进 一步包括:
对应关系配置子单元 15, 用于在本地配置用户信息与短消息服 务中心地址的对应关系;
第四地址获取子单元 16, 用于根据对应关系配置子单元 15配置 的用户信息与短消息服务中心地址的对应关系,以及该消息中携带的 用户信息, 获取与该用户对应的短消息服务中心地址。
通过使用以上各实施例提供的互通服务器,由互通服务器获取短 消息服务中心地址并添加在由基于 SIP协议的消息转换后得到的短 消息中, 使得格式转换后的短消息能够路由到短消息服务中心, 实现 了基于 SIP协议的消息在格式转换后在传统网络中的路由。
本发明实施例还提出一种基于 SIP协议的消息在传统网络中路 由的系统, 包括互通服务器, 该互通服务器可以用于接收该基于 SIP 协议的消息,获取与该基于 SIP协议的消息相关的终端所对应的短消 息服务中心地址, 将该基于 SIP协议的消息转换为短消息, 以及将获 取到的该短消息服务中心地址添加在该短消息中并发送。该系统中的 互通服务器的具体实现, 在前述已有详细描述, 因此这里不再赘述。
