呈现业务接入装置， 呈现业务系统及发布 和获取呈现信息的方法
本申请要求于 2006 年 2 月 25 日提交中国专利局、 申请号为 200610033962.2> 发明名称为 "一种呈现业务接入装置， 呈现业务系统及 发布和获取呈现信息的方法 "的中国专利申请的优先权， 其全部内容通过 引用结合在本申请中。 技术领域
本发明涉及互联网领域和无线通信领域呈现业务的实现， 本发明尤其 涉及一种发布、 获取呈现信息的系统及方法。 此外， 本发明涉及一种呈现 业务接入装置。
背景技术
呈现业务（PRESENCE SERVICE ), 也称作存在业务， 是一种搜集和 分发呈现信息的通信业务。 目前通常和即时消息业务 （INSTANT MESSAGE SERVICE )—起提供， 当然呈现业务也可以单独提供， 或者和 其他业务如网络游戏结合。 因特网工程任务組 IETF、 开放移动联盟 OMA 等国际标准组织都已经初步制订了呈现业务的相应标准规范， 正在不断完 善之中。 本发明中主要使用 RFC 2778中的术语， 将向呈现业务提供呈现 信息的实体或用户称为呈现体（PRESENTITY ), 向呈现业务请求呈现信 息的实体或用户称为观察体 ( WATCHER )。 呈现业务的用户可以是自然人 或非自然人， 即呈现体和观察体都可以对应自然人或非自然人。 呈现信息 包括呈现体的在线 /离线状态、通信方式等基本信息夕卜，还包括心情、位置、 活动等扩展信息， 以及非自然人提供的增值业务信息， 如天气预报、 电台 或电视节目， 交通状况等信息。 在 IETF和 OMA发布的相关标准草案中， 目前都是基本针对自然人的， 而对非自然人呈现信息的发布并没有进行研 究， 而已经商用的即时消息业务中也没有提供非自然人的呈现信息， 实际 上非自然人呈现信息的发布与自然人呈现信息的发布有着很大的差异。
现有呈现业务系统的系统结构图如图 1所示，即自然人呈现体 11、 12、 13 直接将各自的呈现信息发布到呈现服务器 14， 呈现服务器将这些呈现 信息分发给相应的观察体客户端 15。如果采用非自然人呈现体直接与某一 个呈现服务器连接， 由呈现服务器直接通过 SIP/IP ( Session initiation protocol , 会话起始协议 / Internet Protocol , 因特网协议 )核心网分发呈现 信息给观察体客户端， 当一个非自然人呈现体的信息服务业务量很大时， 全部呈现信息都由与其直连的呈现服务器负责转发， 会造成该呈现服务器 负荷极大， 难以满足业务发展的需要。 而且， 通常由用户归属地的呈现服 务器负责用户呈现业务信息的转发， 如果该呈现服务器与提供服务的非自 然人呈现体没有连接， 当用户釆用一次性订阅获取呈现信息服务时， 订阅 请求消息无法发送到非自然人呈现体。而且，对于不同的非自然人呈现体， 如无线电台呈现体和交通信息呈现体要提供的呈现信息内容格式是不同 的， 很难抽象出一个类似自然人的数据模型来统一描述非自然人的呈现信 息。 另外， 对于非自然人呈现体向观察体客户端提供的信息通常都是需要 进行收费的， 而且不同的非自然人提供的信息费率也通常是不同的。 以上 这些差异使呈现业务很难用和自然人一样的方式类似处理非自然人的呈 现信息。 因此， 随着呈现业务的发展， 信息类呈现信息的转发应当由用户 归属地的呈现服务器负责用户呈现信息的发送。但是如何将大量各种类型 的非自然人呈现体接入到各地的呈现服务器上， 如何保证接入的一致性及 安全性， 使呈现业务的接入与控制相分离， 是呈现业务发展需要解决的主 要问题。

具体实施方式
为了便于本领域一般技术人员理解和实现本发明， 现结合附图描述本 发明的实施例。
本实施例提供的呈现业务接入装置由呈现体通讯模块、 业务调度控制 模块构成， 用于连接呈现体和呈现服务器。 呈现体通讯模块， 用于检测接 收到的呈现信息是否符合预先设置的模式定义。 业务调度控制模块， 用于 的分发。
参照图 2, 图 2示出了本发明呈现业务接入装置第一实施例的原理框 图：
本发明呈现业务接入装置 20将呈现体 11、 12、 13接入到呈现服务器 14。 该装置主要包括'. 呈现体通讯模块 21和业务调度控制模块 22。 其中， 呈现体通讯模块 21 用于检测来自呈现体的呈现信息是否符合预先设置的 模式定义，并将符合模式定义的呈现信息交给业务调度控制模块 22; 由业 务调度控制模块 22根据呈现体与呈现服务器的对应关系将呈现信息分发 到呈现服务器 14。
如图 3所示， 是本发明呈现业务接入装置的一种扩展实施例示意图。 通过在呈现业务接入装置中的连接控制模块 23对向其发送呈现信息的呈 现体客户端进行身份认证， 并对接收到的呈现信息创建日志记录。 呈现服 务器通讯模块 24可以才艮据业务量对呈现信息的发送流量进行动态控制。 管理信息库 25用于统一存储各种系统数据， 系统管理模块 26用于业务管 理和系统监控， 以及维护管理信息库中存储的数据。 呈现业务接入装置中 还可以设置计费处理模块 27，以根据接收到呈现服务器返回的信息生成原 始话单记录， 记录观察体客户端接收到呈现信息的信息， 如呈现体和观察 体的标识 （如统一资源标识符 URI、 电话号码等）， 接收时间等， 提供给 系统中的计费中心， 计费中心根据此信息及费率计算观察体用户的业务费 用。
为了保证呈现业务接入装置将支持不同协议的呈现体接入到不同的 呈现服务器，本发明装置中还设置了协议转换模块 28, 与呈现体通讯模块 或呈现服务器通讯模块相连， 用于呈现体通讯模块或呈现服务器通讯模块 在接收和分发呈现信息时进行通讯协议转换。 在该实施例中， 、议转换模 块 28与呈现服务器通讯模块 24相连。
与图 2所示本发明装置第一实施例相比， 本实施例中增加的各模块可 根据实际应用需要来任意选用。 本发明还提供一种应用了上述呈现业务接 入装置的呈现业务系统， 如图 4所示， 在该实施例中， 本发明的呈现业务 系统包括呈现体 11、 12、 13 , 呈现业务接入装置 20, 呈现服务器 14, 观 察体客户端 15。 下面参照附图 4描述本发明的呈现业务系统。
呈现体与呈现业务接入装置连接， 向呈现业务接入装置发布呈现信 息。 呈现体包括自然人和非自然人呈现体， 通常非自然人呈现体为业务提 供商（SP )的应用服务器。 呈现信息可以是文本呈现信息、 多媒体呈现信 息或呈现信息的相关链接等。 呈现体可将呈现信息发送给呈现业务接入装 置， 呈现业务接入装置对发送呈现信息的呈现体进行身份认证， 并对接收 到的呈现信息进行检测， 根据观察体订阅列表向呈现服务器转发呈现信 呈现服务器用于接收、 存储呈现业务接入装置发送的呈现信息， 并向 观察体客户端分发呈现信息。
观察体客户端包括观察体和观察体用户代理， 观察体用户代理作为观 察体用户和系统交互的平台； 观察体用于接收呈现服务器发送来的呈现体 的呈现信息。 观察体客户端的观察体可分为查询体和订阅体： 查询体仅简 单地请求查询呈现体用户的用户信息； 而订阅体则可通过订阅方式， 当呈 现体用户的用户信息发生变化时， 能及时接收到更新的呈现信息。
根据以下具体实例描述本发明的呈现业务系统和呈现业务接入装置。 呈现体通过呈现协议如会话初始协议（SIP ) 向呈现业务接入装置发 布呈现信息， 在 SIP PUBLISH 消息中， 包括呈现体统一资源标识（U I ) 及 XML格式的呈现信息，呈现业务接入装置可以预先存储允许接入的呈现 体 IP地址或 U I标识列表， 接收到 SIP PUBLISH消息时， 检查发送该消息 的呈现体的 IP地址或 URI标识是否在列表中， 如果在列表中则允许接入， 否则拒绝接入。 为了控制呈现体在呈现业务接入装置上的信息的发布， 可 在呈现业务接入装置上存储发布授权规则策略， 呈现业务接入装置根据授 权规则接收呈现信息，可使用可扩展标志语言 XML配置授权规则，如可用 "identity"元素中包含的子元素指定授权发布的呈现体的统一资源标识符 URI:
<identity><id entity="user@example.com"/></identity>
如上表示 URI为 "user@example.com" 的呈现体有权限向呈现业务接 入装置发布呈现信息， URI可以为多个， 构成授权列表。
将授权列表等授权规则策略的 XML文件存储呈现业务接入装置中， 接收呈现信息后， 连接控制模块根据授权列表进行身份认证后， 呈现体通 讯模块可以对接收到的呈现信息进行检测是否符合预先设置的 XML模式 定义。 由于不同的非自然人呈现体的呈现信息内容格式不同， 每种非自然 人呈现体的呈现信息至少有一个预先定义的 XML Schema文件，通过将非 自然人呈现体的 ML Schema文件预先存储在呈现业务接入装置中，对呈 现信息进行检测， 可以使呈现服务器不必再检测呈现信息是否符合预先定 义的格式， 有效降低了呈现服务器的负担。 具体的， 在呈现体发布的呈现 信息消息内容中， 其中的 "presence" 元素的属性 "xmlns" 可以指定该呈 现体的呈现信息所使用的名称空间即对应的 XML Schema, 呈现体通讯模 块据此验证呈现信息。 另外在呈现信息消息中还可以设置一个标志元素， 默认值为 0, 在呈现体通讯模块验证通过后， 将该标志元素的值设置为 1 , 则当呈现业务接入装置将呈现信息转发给呈现服务器后， 呈现服务器检测 到呈现信息中该标志元素的为 1 , 则不再进行险证。 如果有些呈现体如自 然人呈现体不通过呈现业务接入装置发布呈现信息， 则呈现服务器还要对 其发布的呈现信息进行验证。
由于呈现业务接入装置可能有多个， 如图 5所示， 呈现业务接入装置 20用于将呈现体 11、 12、 13接入呈现服务器 14, 呈现服务器 14接收、 存储呈现业务接入装置 20发送的呈现信息， 并向观察体客户端 15分发呈 现信息。 同样， 呈现业务接入装置 30用于将呈现体 31、 32、 33接入呈现 服务器 34，呈现服务器 34接收、存储呈现业务接入装置 30发送的呈现信 息， 并向观察体客户端 35分发呈现信息。
在有多个呈现接入装置的情况下， 可以通过汇接装置 40连接呈现业 务系统中的各呈现业务接入装置， 而且可以在汇接装置 40中保存观察体、 呈现体的订阅关系， 根据观察体和呈现服务器的归属关系， 呈现业务接入 装置和呈现服务器的对应关系等路由信息， 如呈现服务器、 观察体用户标 识（如手机号码、 SIP U I )、 非自然人呈现体标识（如 IP地址， SIP U I 等）等的对应关系表， 呈现业务接入装置 20、 30通过汇接装置进行路由 查询和路由更新， 各呈现业务接入装置将查询到的路由信息在本地緩存， 汇接装置也可以将更新的路由信息下发给各呈现业务接入装置。 呈现业务 接入装置之间可以基于 TCP/IP协议进行呈现信息的转发。
具体的过程为呈现体向归属的呈现业务接入装置发布呈现信息， 归属 的呈现业务接入装置从汇接装置查询路由信息或者查询本地緩存的路由 信息， 根据订阅关系数据确定哪些观察体订阅了该呈现信息， 然后根据观 察体和呈现服务器的归属关系确定要向哪些呈现服务器转发呈现信息， 再 根据呈现业务接入装置和呈现服务器的对应关系数据， 确定向哪些呈现业 务接入装置转发， 当一个呈现业务接入装置接收到转发的呈现: ί言息后， 由 该呈现业务接入装置通过对应的呈现服务器将呈现信息分发给订阅的观 察体客户端。 为了筒化处理， 也可以让呈现体归属的呈现业务接入装置将 呈现信息发送给所有连接的其他呈现业务接入装置， 每个呈现业务接入装 置再发送给所有连接的呈现服务器， 如果呈现服务器没有查询到观察体订 阅了呈现体的呈现信息， 则不发送， 有则发送。 因为对于非自然人呈现体 提供的呈现信息通常为增值业务信息， 一般每个呈现服务器上都会有一些 观察体用户订阅这些信息， 所以这种处理方法也是比较合理的。 上述路由 方法需要在汇接装置中存储观察体、 呈现体的订阅关系， 实际上这个数据 比较多， 现有技术在呈现服务器中已经存储了， 用于呈现服务器分发呈现 信息， 根据上面的路由过程可以发现， 实际并不需要完整观察体、 呈现体 的订阅关系数据， 而只需要呈现体和订阅该呈现体呈现信息的观察体所归 属呈现服务器的对应关系即可， 这个对应关系数据很小, 检索速度很快， 而且也不用经常更新， 如一个呈现服务器上的观察体订阅了一个呈现体的 呈现信息， 归属于同一呈现服务器的另一个观察体也订阅了同一呈现体的 呈现信息， 则不必更新上述的对应关系数据。
为了增强安全性， 还可以预先设置呈现体发布呈现信息的限制条件， 如发布频率上限、 发布时间、 发布消息数量上限， 当呈现业务接入装置接 收到 SIP PUBLISH消息时，首先检查是否满足条件。在允许接入列表中存 储相关限制信息， 如表 1所示：
Figure imgf000012_0001
表 1
为了使用上述限制条件如发布频率或发布消息数量， 连接控制模块对 接收的呈现信息创建日志记录， 记录下每条消息的成功接收时间、 发送呈 现信息的呈现体及与呈现信息的相关信息， 并据此来计算实际发布频率、 数量， 然后检验是否满足预先设置的限制条件。
呈现业务接入装置将符合预先设置的模式定义的呈现信息转发到呈 现服务器。 可以将处理自然人呈现信息的呈现服务器与处理非自然人呈现 信息的呈现服务器分别单独设置， 以使系统的处理更加简单高效。
另外，呈现业务接入装置可以通过增加呈现服务器通讯模块根据业务 量对发送流量进行动态控制。 呈现服务器通讯模块依据呈现服务器上报的 呈现服务器的业务量来动态调整向呈现服务器发送的消息流量， 以免呈现 服务器处理负荷过大，导致系统瘫痪。或预先对不同的呈现体设置优先级， 按优先级顺序发布呈现信息。 也可以同时考虑等待时间和优先級， 如用两 者的乘积值来衡量呈现信息的发布顺序。
通过在呈现业务接入装置中增加管理信息库模块用于统一存储各种 系统数据， 如上述的允许接入列表、 非自然人的可扩展标记语言模式定义
XML Schema, 非自然人呈现体与呈现服务器的对应表及呈现信息的收发 记录等数据。 并将数据提供给系统中的各个模块使用。 还可以通过增加系 统管理模块用于业务管理和系统监控， 以及维护管理信息库中存储的数 据。 业务管理主要包括完成业务的统计报告、 生成报表、 系统添加、 修改 和删除相关配置数据，如上述的允许接入列表、非自然人的 XML Schema, 非自然人呈现体与呈现服务器的对应表等。 系统监控主要包括完成对呈现 业务接入装置的监控、 查询、 操作和维护的管理， 例如显示监控当前的系 统处理负荷数据， 当检测到其超过一定负荷值时进行报警提示。
另外， 在呈现业务接入装置中增加协议转换模块， 用于呈现服务器、 呈现体进行连接的通讯模块之间的协议的转换。 呈现体与呈现业务接入装 置之间可以采用 SIP协议通信， 而呈现业务接入装置与呈现服务器之间可 以直接通过 TCP/IP协议进行通信， 协议转换模块则可以将接收到的 SIP 消息转换成相应的 TCP/IP协议消息后发送出去。
呈现服务器接收到呈现信息根据观察体订阅列表将呈现信息分发给 对应的观察体客户端。 呈现 务器首先保存收到的呈现信息， 然后查询订 阅呈现信息的观察体列表， 将新的呈现信息通过 SIP NOTIFY消息发送给 对应的观察体客户端。
由于自然人的呈现业务一般不需要进行计费， 而非自然人呈现体提供 的增值业务信息一般是需要进行计费的 , 所以呈现业务接入装置可以增加 计费处理模块， 用于产生呈现业务的原始话单记录 CDR ( Call Detail Record ), 计费记录， 并与计费中心交互， 通过 FTP协议将计费文件传送 给计费中心。 具体可以通过以下两种方式实施：
第一种计费方式： 在呈现业务接入装置中设置计费处理模块， 由于呈 现体发送的呈现信息中并不包括观察体的信息， 即呈现业务接入装置无法 确定哪些观察体客户端会接收到呈现信息， 因此在呈现业务接入装置将呈 现信息发送给呈现服务器之后， 由呈现服务器根据订阅呈现信息的观察体 列表将呈现信息并进行分发， 在分发完成后呈现服务器向呈现业务接入装 置返回发布消息确认， 其中包括成功发送呈现信息的观察体列表， 呈现业 务接入装置的计费处理模块根据接收到的信息生成原始话单记录， 记录观 察体客户端接收到呈现信息的信息， 如呈现体标识 U I, 接收时间等， 提 供给计费中心， 计费中心根据此信息及费率计算观察体用户的业务费用。 当然虽然呈现业务接入装置无法确定哪些观察体客户端会接收到呈现信 息，但是可以根据汇接装置中的存储的观察体和呈现体的订阅关系确定呈 现服务器会向哪些观察体客户端发送呈现信息， 这样呈现服务器只要在呈 现信息发送完成向呈现业务接入装置返回发送失败的呈现信息的观察体 列表即可， 这个列表的数据量要比成功发送呈现信息的观察体列表少很 多。 对于发送失败的观察体呈现业务接入装置不生成计费记录。
第二种计费方式： 由于计费处理模块位于呈现业务接入装置中， 需要 呈现服务器向其返回观察体列表， 无论是成功的还是失败的， 呈现业务接 入装置才能进行计费， 处理效率较低， 可以直接在呈现服务器中设置计费 处理模块， 根据向观察体客户端分发呈现信息的情况生成原始话单记录。 对于频繁发布的呈现信息可以由呈现服务器计费； 或者采用包月计费的方 法， 以简化计费处理， 如股票信息， 频繁发布更新呈现信息， 可以采用包 月或按天计費的方法。
利用上述呈现业务系统， 本发明还提供了发布和获取呈现信息的方 法， 其基本思想是： 呈现体在呈现业务接入装置上发布呈现信息， 呈现业 务接入装置对呈现体进行身份认证， 检测接收到的呈现信息是否符合预先 设置的模式定义， 对于符合模式定的呈现信息根据对应的观察体订阅列表 相呈现服务器发送， 呈现服务器将呈现信息发送给相应的观察体客户端。 下面参照附图 6对本发明进行详细的描述。
如图 6所示， 本发明方法的一个实施例包括下列步骤：
1、 呈现体向呈现业务接入装置发布呈现信息； 2、 呈现业务接入装置接收呈现信息， 对发布呈现信息的呈现体进行 身份认证， 并检测所接收的呈现信息是否符合预先设置的模式定义；
3、 呈现业务接入装置向呈现服务器发送呈现信息；
4、 呈现服务器将根据观察体订阅列表将呈现信息分发给相应的观察 体客户端。
以下详细描述本发明的方法实例。
呈现体发布呈现信息到呈现业务接入装置， 呈现业务接入装置对发布 呈现信息的呈现体进行身份认证， 将符合模式定义的呈现信息发送到呈现 服务器， 呈现服务器根据相应的订阅关系将呈现信息分发给观察体客户 端。 呈现信息的发布、 接收的具体处理流程如下：
101、 呈现体通过呈现协议向呈现业务接入装置发布呈现信息。 呈现 信息包括文本呈现信息、 多媒体呈现信息或呈现信息的相关链接。
201、 呈现业务接入装置接收呈现信息， 呈现体与呈现业务接入装置 之间可以采用 SIP协议通信， 对发布呈现信息的呈现体进行身份认证。 检 查发送该消息的呈现体的 IP地址或 U I标识是否在列表中， 如果在列表 中则允许接入， 否则拒绝接入。
由于系统中的呈现业务接入装置和呈现服务器可以有多个 , 假设在系 统中接入多个呈现业务接入装置和呈现服务器， 呈现业务接入装置间通过 汇接装置连接。 在此步驟中， 呈现业务接入装置需要从汇接装置获取路由 信息， 并才 据所述路由信息中呈现体、 呈现服务器、 呈现业务接入装置及 观察体的对应关系列表将呈现信息转发给要接收所述呈现信息的观察体 客户端归属的呈现服务器所对应的呈现业务接入装置。
202、 呈现业务接入装置检测验证所接收的呈现信息是否符合预先设 置的模式定义。
203、 呈现业务接入装置向呈现服务器发送呈现信息。
在此步骤中， 呈现业务接入装置还可以依据呈现服务器上报的呈现服 务器的业务量来动态调整向呈现服务器发送的消息流量， 以免呈现服务器 处理负荷过大。 或预先对不同的呈现体设置优先级， 按优先级顺序发布呈 现信息。 也可以同时考虑等待时间和优先级， 如用两者的乘积值来衡量呈 现信息的发布顺序。
如果呈现业务接入装置与呈现服务器之间直接通过 TCP/IP协议进行 通信， 此步骤还包括将接收到的 SIP消息转换成相应的 TCP/IP协议消息 然后再发送。
301、 呈现服务器保存接收呈现业务接入装置发送的呈现信息。
302、 呈现服务器查询订阅呈现信息的观察体列表， 将呈现信息通过 SIP NOTIFY消息发送给对应的观察体客户端。
倘若呈现业务涉及计费的增值业务， 此步驟后分两种方法：
第一种方法： 计费处理模块位于呈现服务器中， 则呈现服务器根据向 观察体客户端分发呈现信息的情况生成原始话单记录。
第二种方法： 计费处理模块位于呈现业务接入装置中， 则继续以下步 骤：
303、 呈现服务器分发完成后向呈现业务接入装置返回发布消息确认， 其中包括成功发送呈现信息的观察体列表。
304、 呈现业务接入装置的计费处理模块根据接收到的信息生成原始 话单记录，记录观察体客户端接收到呈现信息的信息，如呈现体标识 URI, 接收时间等， 提供给计费中心。
305、 计费中心才艮据此信息及费率计算观察体用户的业务费用。
虽然通过实施例描绘了本发明， 但本领域普通技术人员知道， 在不脱 离本发明的精神和实质的情况下， 就可使本发明有许多变形和变化， 本发 明的范围由所附的权利要求来限定。
