Description

即时消息与电子邮件互通的方法与系统 技术领域
本发明涉及即时消息与电子邮件互通技术, 尤其涉及一种即时消息与 电子邮件互通的方法与系统。 背景技术
电子邮件 (E-mail )是 Internet应用最广的服务之一, 通过网络的电子 邮件系统, 用户可以用非常低廉的价格与世界上任何一个角落的网络用户 联系, 这些电子邮件可以是文字、 图像、 声音等各种方式。 每一个电子邮 件用户都会有一个电子邮件地址, 电子邮件地址的典型格式是 abc@xyz, 这里 @之前是代表个人用户的字符组合或代码, @之后是为用户提供电子邮 件服务的服务器名, 如 user@hotmail.com。 涉及到的基础协议主要有: 简单 邮件传输协议 ( SMTP, Simple Mail Transfer Protocol )、 邮局协议 3 ( P0P3 , Post Office Protocol 3 )等。 而即时消息 ( IM, Instant Message )是 Internet 提供的另外一种业务, 即将接收到的发送者发来的信息非存储地转发给接 收者, 接收端与发送端之间可以直接交互消息。 涉及到的协议有: 可扩展 消息与存在协议 ( XMPP, Extensible Message and Presence Protocol )、 SIP 扩展协议 ( SIMPLE , SIP Instant Message and Presence Leveraging Extensions ) 和消息会议中继协议( MSRP , Message Session Relay Protocol )等。 目前, 利用基于会话初始协议(SIP, Session Initiation Protocol ) 的协议实现即时 消息是一种发展方向。
互联网内的消息业务主要是上述两种: 电子邮件和即时消息。 对用户 而言, 一方面在使用电子邮件、 即时消息等互联网通信工具, 另一方面也 在使用短消息、 多媒体消息等电信网络通信方式。 目前, 业界提出了融合 消息业务, 目的在于使用户可以在任何时间、 任何地点, 使用不同的技术、 媒介和用户终端与任何人进行消息交互。 为了实现融合消息业务, 一种方 式是提供融合消息业务系统, 该系统提供给业务用户完善一致并且方便的 消息业务体验, 业务用户之间可以以基于即时消息技术的融合消息交互, 并可以与非此业务用户且是上述提及的各类传统消息业务用户之间交互。 其中互通的一个重要方面就是融合消息和电子邮件的交互。 因为融合消息 是基于即时消息技术的, 所以融合消息和电子邮件的交互实现可以建立在 即时消息和电子邮件交互的实现基础上。

图 1为即时消息与电子邮件的互通的结构示意图;
图 2为本发明即时消息转换为邮件的流程图;
图 3为本发明即时消息转换为邮件的另一流程图;
图 4为本发明邮件转换为即时消息的流程图;
图 5为本发明邮件转换为即时消息的另一流程图;
图 6为本发明即时消息与电子邮件互通的系统的组成结构示意图。 具体实施方式
本发明的基本思想是: 通过在即时消息系统与邮件服务器之间设置互 通服务器而实现对用户发送的即时消息及邮件进行相应的转换, 然后再发 送至即时消息及邮件中目的用户所对应的邮件地址及即时消息接收地址, 从而实现即时消息及邮件之间的自由互通。
为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
图 1为即时消息与电子邮件的互通的结构示意图, 如图 1所示, 通过 在即时消息系统和电子邮件服务器之间设置互通服务器, 或称互通网关实 现即时消息与电子邮件的交互, 来自即时消息系统源用户即用户 A的即时 消息可以经由互通服务器转换为邮件, 并发送给邮件服务器, 由邮件服务 器转发给目的用户即用户 B; 上述的邮件目的用户即用户 B可以直接回复 邮件, 经互通服务器转换为即时消息至上述即时消息源用户即用户 A。
本发明中, 互通服务器在接收到即时消息系统的即时消息并转换为邮 件发送时, 是作为一个邮件客户端的角色, 而在接收邮件并转换为即时消 息时, 是作为一个邮件服务器的角色, 必需有作为邮件服务器的服务器域 名。 本发明可以将即时消息系统的域名配置作为互通服务器的域名, 如果 有多个即时消息系统同时连接同一个互通服务器, 则互通服务器配置多个 域名, 每个域名对于于一个即时消息系统。 即时消息中的用户标识以 SIP URI ( Uniform Resource Identifier ) 表 示 , 格 式 为 sip:usemame@messageDomain.com; 由 Tel URI转换成 SIP URI的格式为 sip:+86-13812345678@messageDomain.com。 邮件系统中的邮件地址格式为 user@emailDomain. com。 在这种情形下, 即时消息中的源用户在邮件系统 中的邮件地址由源用户的 SIP标识对应,即把 SIP URI中的用户名映射为邮 件地址中的用户名, SIP URI中的域名映射为邮件地址中的域名。 反之, 由 邮件地址构造 SIP用户标识则反向对应。
本发明中的互通服务器还可以拥有一个独立的邮件服务器域名, 与之 相连的即时消息系统的即时消息用户如果申请了与电子邮件交互的业务, 则会被预配置一个交互发生时使用的邮件地址, 此邮件地址的域名即为互 通服务器的域名; 此邮件地址的用户名是用户设置或邮件服务器分配的。 在这种情形下, 即时消息中的源用户在邮件系统中的邮件地址即为预配置 的邮件地址。 预配置的邮件地址可以统一存储在互通服务器或即时消息系 统中; 也可以统一存储在外部的一个用户信息管理服务器中, 由互通服务 器读取; 其中, 用户信息管理服务器为专设的服务器, 用于存储用户标识 与邮件地址的对应关系。
通过上述两种方式, 在即时消息用户的用户标识和对应邮件地址或预 配置邮件地址之间建立了——对应关系, 互通服务器按照此对应关系进行 转换; 并且可以以此对应邮件地址或预配置邮件地址向即时消息用户发送 邮件, 因为此邮件地址的域名为互通服务器的域名, 所以此邮件将发送至 互通服务器, 由互通服务器转换为即时消息至即时消息用户, 从而实现互 通。
即时消息中的目的用户即接收消息用户的邮件地址构造分为两种情 况: 当源用户直接向目的用户的邮件地址发起即时消息时, 目的用户的邮 件地址即由即时消息中的目的用户标识对应。 另外, 目的用户的邮件地址 也可以由互通服务器查询系统外部的用户信息管理服务器获取。 或者, 源 用户发起即时消息时, 互通服务器根据目的用户的用户标识获取目的用户 的邮件地址。
以下通过具体的示例, 详细说明是如何实现即时消息与邮件互通的。 假设用户 A是即时消息类业务的用户, 用户 B是电子邮件业务用户, 为突出要点起见, 用户 A到互通服务器之间经过的其它系统不作描述。
即时消息可分为寻呼模式和大消息模式, 按照这两种不同方式, 互通 服务器釆取不同的处理方式。
用户 A发起寻呼模式即时消息至用户 B的过程为: 当互通服务器接收 到用户 A终端以寻呼模式发起的即时消息 (SIP Message ) 时, 互通服务器 翻译此即时消息, 并按照 SMTP协议进行参数构造, 生成符合电子邮件格 式的电子邮件, 并向用户 B所属的邮件服务器发出电子邮件。 图 2为本发 明即时消息转换为邮件的流程图, 如图 2所示, 互通服务器处理即时消息 转换为邮件的步骤如下:
步骤 201 : 发起域名服务器(DNS, Domain Name Server )查询, 获取 目的用户即用户 B所属的 SMTP服务器的地址。
互通服务器按照目的用户即用户 B的邮件地址的域名发起 DNS查询。 此邮件地址可以是上文所述的即时消息中用户标识对应的邮件地址, 也可 以是互通服务器直接查询系统外部的用户信息管理服务器获取的用户 B的 邮件地址。 具体的, 即时消息用户 A生成的即时消息中是以用户 A的标识 作为源发送方标识, 用前述方法构造用户 A的邮件地址; 可以用户 B的标 识作为目的用户的标识, 也可直接以用户 B的邮件地址作为目的用户的标 识。 当用户 B的邮件地址作为目的用户的标识时, 互通服务器利用用户 B 的邮件地址中的域名进行域名解析, 获取用户 B邮件地址所在的邮件服务 器即 SMTP服务器; 而当以用户 B的标识作为目的用户的标识时, 互通服 务器接收到即时消息时, 通过用户信息管理服务器由用户 B的标识信息查 找其对应的邮件地址, 从而获取的用户 B的邮件地址。
步骤 202: 建立与 SMTP服务器即邮件服务器的传输通道,并进行参数 映射, 把即时消息中相关参数对应转换为 SMTP命令。
互通服务器对 SMTP命令的参数构造按照以下对照进行: SMTP命令 MAIL FROM中的返回地址 (reverse-path )参数为源用户即用户 A的邮件 地址, 此邮件地址可以是上文所述的用户 A标识所对应的邮件地址, 也可 以是互通服务器直接从外部的用户信息管理服务器获取的预配置的邮件地 址; SMTP命令 RCPT TO中的传递地址( forward-path )参数即为步骤 201 中的目的用户的邮件地址。 如果是将用户 A的号码标识直接作为邮件的用 户名, 则互通服务器根据其自身的域名直接生成用户 A的邮件地址, 如前 述的 +86-13812345678@messageDomain.com等, 或者, 互通服务器根据用 户 A的标识从用户信息管理服务器中获取用户 A设置的电子邮件地址, 该 邮件地址是用户设置的任意电子邮件地址, 或是互通服务器为用户 A分配 的任意电子邮件地址。
步骤 203 : 把即时消息中相关参数按照电子邮件格式映射构造邮件消 息。
互通服务器对邮件消息的邮件头中参数的构造按照以下对照进行: 上 述步骤 202中的源用户的邮件地址映射为 from参数; orig-date参数可以设 置为即时消息中的 date 或由互通服务器设置为本地当时时间; message-id 参数由互通服务器产生; to 参数与 RCPT To 命令中的传递地址 ( forward-path )相同; 如果即时消息中包含 subject参数, 则对应为邮件头 subject参数; 当即时消息中递送通知 ( imdn.Disposition-Notification )设置 为 " positive-delivery,, 或者 " negative-delivery,, 或者同时设置 " positive-delivery ,, 及 " negative-delivery ,, , 而 设 置 Disposition-Notification-To 为必需 ( required ) ; 当即时消息中递送通知 ( imdn.Disposition-Notification ) 设置为显示 ( display ) , 则设置 disposition-type 为显示 (displayed ); 如果即时消息的消息内容类型为文本 ( text/plain ), 则直接把消息内容作为邮件体; 如果即时消息的消息内容类 型为多用途互联网邮件扩展 ( MIME , Multipurpose Internet Mail Extensions ) 类型 , 则按照 MIME邮件格式构造 MIME邮件头和邮件体。
步骤 204: 发起邮件事务, 向目的用户发出消息, 并等待响应。
互通服务器向目的用户即用户 B所属的邮件服务器发出 DATA指令, 待邮件服务器返回 354 Intermediate reply后即发出步骤 203中构造的邮件, 并保持事务, 等待发送完所有数据后的响应。
步骤 205: 收到正确响应后,构造成功响应消息例如 SIP 202接受消息, 否则构造出错响应消息; 并把响应消息发送给即时消息系统中用户 A的终 端。
用户 A发起大消息模式即时消息至用户 B的过程为: 当互通服务器接 收到用户 A终端以大消息模式发起的即时消息时, 上述互通服务器首先收 到起呼消息例如 SIP Invite消息,之后收到一至若干个 MSRP ( The Message Session Relay Protocol )协议的 MSRP SEND 消息, 则互通服务器緩存在 MSRP SEND消息中收到的消息内容, 然后翻译起呼消息,按照 SMTP协议 进行参数构造, 生成符合电子邮件格式的电子邮件, 并向用户 B所属的邮 件服务器发出电子邮件。 图 3为本发明即时消息转换为邮件的另一流程图, 如图 3所示, 互通服务器处理即时消息转换为邮件的步骤如下: 步骤 301 : 当接收到大消息模式会话请求消息时, 如无错误则首先返回 确认消息, 否则返回出错消息。
步骤 302: 当接收到后续的携带消息内容的 MSRP SEND请求消息时, 临时存储请求消息中的消息内容, 直至接收完所有的 MSRP SEND请求消 息后, 把所有接收的消息内容构建成一个完整的消息内容。
步骤 303: 发起 DNS查询, 获取目的用户即用户 B所属的 SMTP服务 器的地址。
步骤 304: 建立与 SMTP服务器的传输通道, 并进行参数映射, 把即时 消息中相关参数按照 SMTP协议转换。
步骤 305:把即时消息中参数及步骤 304获得的消息内容按照电子邮件 格式映射构造邮件消息, 其中步骤 302 中临时存储的消息内容构造为邮件 内容。
步骤 306: 向目的用户即用户 B所属的邮件服务器发出邮件消息,并等 待响应。
步骤 307: 收到正确响应后,构造成功响应消息例如 SIP 202接受消息, 否则构造出错响应消息, 发送给终端。
上述步骤 303至步骤 305中, 除了邮件内容的构造不同外, 其他均与 前述的用户 A发起寻呼模式即时消息至用户 B中描述的相同。
用户 B向用户 A发送电子邮件的情形有两种, 一种是用户 B对用户 A 发出的即时消息并经互通服务器转换后的电子邮件进行直接回复, 另一种 是用户 B直接向用户 A发出电子邮件。 两种情况下, 发送者地址均为用户 B的邮件地址, 接收者地址为用户 A的对应邮件地址或预配置邮件地址。
当互通服务器接收到用户 B所属邮件服务器发起的电子邮件时, 上述 互通服务器翻译 SMTP协议携带的邮件消息内容, 进行电子邮件至即时消 息参数构造, 生成符合即时消息格式的即时消息, 并按照消息的大小, 釆 用寻呼模式或大消息模式向用户 A发出即时消息。
用户 B发起电子邮件至寻呼模式即时消息的转换过程: 互通服务器接 收 EHLO或 HELO及后续的 SMTP命令例如 MAIL FROM, RCPT TO命 令后,等待 DATA数据接收完成,判断当邮件内容字节数不超过 1300字节, 互通服务器构造寻呼模式即时消息, 其中, 1300字节寻呼模式下单个即时 消息的最大字节数。 图 4为本发明邮件转换为即时消息的流程图, 如图 4 所示, 互通服务器处理邮件转换为即时消息的步骤如下:
步骤 401 :映射 SMTP命令参数及邮件消息头和消息体至寻呼模式即时 消息。
互通服务器对即时消息的消息参数的构造按照以下对照进行: 邮件头 的 from参数映射为即时消息中的源用户标识; 由于是将邮件转换为即时消 息, 因此, 即时消息中的目的用户标示由前述方法邮件地址反向转换生成; 可以直接以用户 B的邮件地址作为即时消息中的源用户标识。 RCPT To命 令参数映射为即时消息中的目的用户标识; 如邮件头包含 subject参数, 则 映射为即时消息中的 subject参数;如邮件头中的 Disposition-Notification-To 参数为 必 需 ( required ) , 则 设 置 即 时 消 息 中 递 送通知 ( imdn.Disposition-Notification ) 设置为 " positive-delivery,, 或者 " negative-delivery" 或者同时设置两者; 如由 牛头中的 disposition-type 为 显 示 ( displayed ) , 则 设 置 即 时 消 息 中 递 送 通 知 ( imdn.Disposition-Notification )设置为显示( display ); 邮件内容映射为即 时消息中的消息体。
本示例适用于邮件内容字节数不超过 1300字节的情形。
步骤 402: 发送即时消息并保持通讯通道, 等待响应。
步骤 403: 收到正确响应消息例如 SIP 200 OK消息后, 构造成功消息 例如 250 OK消息并发向发送端, 否则返回相应出错消息。
用户 B发起电子邮件至寻呼模式即时消息的转换过程: 互通服务器接 收 EHLO或 HELO及后续的 SMTP命令例如 MAIL FROM, RCPT TO命 令后, 等待 DATA数据接收完成, 判断当邮件内容字节数大于 1300字节, 互通服务器构造大消息模式即时消息, 即首先暂存 SMTP命令及邮件消息 参数, 按前述方式映射相应参数生成会话请求消息, 并发起会话请求消息。 收到确认消息后, 再发起若干个 MSRP SEND请求, 传递邮件内容。 收到 MSRP响应后, 发送结束会话请求关闭会话。 图 5为本发明邮件转换为即 时消息的另一流程图, 如图 5 所示, 互通服务器处理邮件转换为即时消息 的步骤如下:
步骤 501 : 互通功能服务器暂存 SMTP命令及邮件消息参数。
步骤 502: 互通功能服务器映射相应参数生成会话请求消息, 并发起会 话请求消息。 会话请求消息经由互通服务器最终到达终端。 终端返回确认 消息。
映射方式与前述步骤 401中相同, 只是映射的内容略有差异而已。 步骤 503:确认消息转至互通服务器后,互通服务器再发起若干个 MSRP
SEND请求 , 传递邮件内容至终端 , 终端返回 MSRP响应。
步骤 504: 互通功能服务器收到 MSRP响应后, 发送结束会话请求关 闭会话。
以上解决方案不限于即时消息, 也适用于基于即时消息扩展的其它即 时交互的消息类业务, 例如正在国际标准组织移动开放联盟 OMA ( Open Mobile Alliance )研究的融合消息 CPM ( Converged IP Messaging )业务。
本发明尤其适合于以下应用场景: ^^定用户 A和用户 B均为融合消息 业务用户, 当用户 B不在线, 用户 B的偏好设置是不在线的情况下把离线 消息发往用户 B的邮箱; 或者, 用户 B在线, 用户 B的偏好设置是目前不 接受即时消息, 而是把融合消息转发至用户 B的邮箱。 在这两种情况下, 通过互通服务器提供的与电子邮件的交互功能, 可以把用户 A发送的融合 消息转换为邮件消息发至用户 B的邮箱。
