Description

一种发布呈现信息的方法和*** 技术领域
本发明涉及一种发布呈现信息的方法和***， 尤其涉及一种具有委托机 制的发布呈现信息的方法和***。
背景技术
目前， 呈现业务的应用越来越广泛， 呈现业务 (Presence Service) 是一 种搜集和发布呈现信息（presence information)的通信业务。可能许多人希望 获取呈现业务用户的呈现信息， 这些人可能包括用户的家人、 朋友， 也可能 包含陌生人， 而很多呈现信息都是用户隐私。 呈现业务使用户可以利用各种 终端， 突破空间与时间的限制， 寻找聊天伙伴、 査询伙伴的状态信息等， 实 现即时的文本与多媒体信息交流。 通过呈现服务器（Presence Server)完成用 户状态的呈现与管理， 根据呈现信息， 可以知道对方是否在线、 正在干什么 (如开会、 吃饭等)、 心情、 客户端能力、 爱好等等信息， 用户可以通过发送 邀请给其它用户， 进行铃声、 图片、 文件等媒体内容共享。
图 1描述了现有技术中实现呈现业务的***结构， 包括呈现体客户端或 者应用服务器（Application Server) 103、 呈现服务器（Presence Server) 102、 观察体客户端 （Watcher) 101和呈现 XDMS (Presence XML Document Management System, 呈现 XML文件管理***） 104; 呈现体客户端或者应用 服务器（Application Server) 103为呈现信息源， 当其呈现信息发生改变时， 主动向呈现服务器 102发送 PUBLISH发布消息， 发布呈现信息。
呈现体客户端与观察体客户端 101可以是移动终端， 如手机、 PDA (掌上 电脑)、 智能终端（例如数字机顶盒）等， 也可以是固定终端， 移动终端上的 上述功能同样可以运用于固定终端中， 目前也出现了具有会话初始化协议
(Session Initiation Protocol, SIP) 功能的固定终端； 呈现体客户端或者应用 服务器 103上有一个用于发布消息的应用程序， 用户可以通过选择发布需要 发布的信息， 确认后， 呈现体客户端或者应用服务器 103将所有消息包括用 户标识符等一并发送到呈现服务器 102。 .
呈现服务器 102负责接收观察体客户端 101的 SUBSCRIBE订阅消息， 根据被订阅的呈现体客户端预先设置的订阅授权规则来判断订阅的结果； 接 收呈现体客户端的 PUBLISH发布消息， 按照呈现体客户端或者应用服务器 103/观察体客户端 101原先设置的一些规则 （包括内容合成、 授权和过滤） 进行处理， 最终通过 NOTIFY通知将呈现信息发布给观察体客户端 101。
观察体客户端 101订阅呈现体客户端或者应用服务器 103的呈现信息， 并接收来自呈现服务器 102的通知消息。
呈现 XDMS 104保存呈现体客户端或者应用服务器 103的授权列表（如 订阅授权列表、 内容授权列表、委托授权列表等）、群组列表等， 其它装置如 呈现信息合成和发布装置可以通过协议如 ML文档配置和访问协议 (XCAP) 直接访问呈现 XDMS104, 也可以通过专用的信息访问单元从呈现 DMS104 中的授权列表中获取一系列的信息， 如订阅授权规则， 内容授权规则、 委托 授权列表等； 当然如果需要， 本领域技术人员可以将呈现 XDMS104直接设 置到呈现服务器 102中， 也可以将两者设置成独立的服务单元， 通过特定的 通信协议进行访问。
上述的 SUBSCRIBE和 PUBLISH等均为 SIP消息。 PUBLISH消息的 SIP 消息头中包含呈现体客户端的标识， 消息体中包含 XML文档， 为呈现体客 户端的呈现信息。订阅和发布消息并不局限于 SIP消息格式， 在 IP多媒体系 统（IP Multimedia Subsystem, IMS) 网络中是 SIP消息； 对于其他网络 （例 如 IP网络中的 ICQMSN应用）， 可以不为 SIP消息， 为自定义的消息格式。 呈现服务器 102包括呈现信息合成和发布装置 105， 呈现信息合成和发布装 置 105是最重要的一个装置， 图 2描述了它的结构， 它包括依次连接的呈现 信息合成单元 211、 内容授权规则检查单元 212、 观察体过滤单元 213、 部分 通知处理单元 214和呈现信息发布单元 215; 呈现信息合成单元 211用于将 新发布的呈现信息和服务器中保存的呈现信息进行合成处理； 内容授权规则 检查单元 212用于按照呈现体客户端设置的规则 （对于某个观察体客户端允 许发布哪些信息），将不允许发布的信息过滤掉；观察体过滤单元 213用于按 照观察体设置的规则（如不希望接收某个呈现体客户端的哪些信息），将不希 望接收的信息过滤掉 （比如观察体仅希望用户从关机变为开机时通知， 其他 呈现信息将被过滤掉）； 部分通知处理单元 214按照观察体客户端 101 在 SUBSCRIBE订阅时设置的规则 （比如只接收用户位置相关的呈现信息）， 将 不属于订阅范围的信息过滤掉； 呈现信息发布单元 215用于将处理后的呈现 信息 NOTIFY通知给观察体客户端 101。上述内容授权规则检查单元 212、观 察体过滤单元 213、 部分通知处理单元 214的先后连接关系可以根据实际需 要设定。
图 3为现有***交互流程图， 具体流程如下：
1 )呈现体客户端 A首先要在呈现 XDMS进行一些设置 （例如订阅授权 规则（允许哪些用户订阅）、 内容授权规则（允许发布哪些信息）等， 呈现服 务器可以通过 XCAP协议来获得这些规则， 或者如果呈现服务器订阅了这些 规则的改变通知， 当这些规则发生改变时， 呈现 DMS会通知呈现服务器。 订阅授权规则 （Subscription Authorization Rule)和内容授权规则 （Content Authorization Rule ) 保呈现一个 XML文件中， 此 XML包括 3个重要的元素 <Condition>、 <Action>、 <Transformation>。 <Condition>表示匹酉己的条件， <Acti0n>表示匹配的结果， （允许、拒绝、友好拒绝、等待确认）， <Condition> 和<八(^011>的组合对应订阅授权规则， 用于按照呈现体客户端设置的规则处 理观察体客户端的订阅请求； <TranSformati0n>对应内容授权规则， 用于按照 呈现体客户端设置的规则（对于某个观察体客户端允许发布哪些信息）， 将不 允许发布的信息过滤掉；
2)观察体 B向呈现服务器请求订阅 （SUBSCRIBE)呈现体客户端 A的 呈现信息；
3)呈现服务器根据呈现 XDMS中的订阅授权规则匹配， 如果匹配， 允 许订阅； 同时保存此订阅关系；
4) 呈现体客户端 A向呈现服务器发布 （PUBLISH)信息；
5)呈现服务器根据一系列的规则处理后向观察体 B发送呈现信息的通知 (NOTIFY) o
上述方案中呈现 XDMS与呈现服务器分离，各种规则保存在呈现 XDMS 上， 呈现体客户端通过聚合代理（Aggregation Proxy)使用 XCAP协议， 或 者应用服务器直接使用 XCAP协议， 或者用户通过人机交互界面 （如网页） 去呈现 XDMS设置和修改各种规则； 现有技术中， 呈现 XDMS也可以和呈 现服务器合并， 各种规则保存在呈现服务器中； 在上述的现有技术中， 呈现 信息的发布者必须是呈现体客户端本身， 始终不太灵活， 用户体验也差， 我 们将上述现有的呈现信息发布方式称之为非委托发布方式； 如果能够委托他 人或者设备代替其本人发布呈现信息， 就能解决上述不足， 例如： 用户 A希 望登陆到游戏服务器玩游戏时， 其呈现状态为 "玩游戏"， 对应的呈现信息可 以包括： 游戏服务器名、 游戏大厅名称、 游戏名称等； 用户 A希望游戏服务 器能够委托其发布呈现信息， 这样他的朋友就可以看到他的状态， 也能够登 陆到相同的游戏服务器和他一起玩游戏。 用户 A就不需要自己手工去发布呈 现信息； 再如某公司老总即将开会， 其要求秘书将其状态设置为 "开会"， 秘 书使用某种软件向呈现服务器发布老总的呈现信息； 显然， 利用委托机制可 以很好地提升用户体验。
但是在现有技术中， 呈现信息的发布者必须是呈现体客户端本身， 现有 技术中的***是无法完成具有委托机制的呈现信息服务的， 这样当用户使用 某种应用时， 无法委托其他实体发布其呈现信息， 需要用户自己登陆另外一 个程序发布呈现信息， 用户体验差， 不灵活， 用户使用某些业务时， 由于对 于业务不熟悉， 此业务具备哪些呈现信息， 用户不清楚， 这样就限制了呈现 信息的内容， 使得业务展现信息贫乏。

具体实施方式
下面结合附图对本发明做进一步的说明。
实施例一
参考图 4， 改进后的***包括呈现体客户端 A403、 受委托的呈现体客户 端 B或者应用服务器 C404、 呈现服务器 102、 观察体客户端 101和呈现 XDMS104, 其中呈现服务器 102包括委托检查和处理装置 405、 呈现信息合 成和发布装置 105， 参考图 5， 具体的订阅和发布流程如下：
1 )呈现体客户端 A403预先在呈现 XDMS104进行一些设置（例如订阅 授权规则（允许哪些用户订阅）、 内容授权规则（允许发布哪些信息）和委托 授权规则 （是否允许委托、 允许委托发布哪些内容等））；
2)观察体客户端 101向呈现服务器 102请求订阅 （SUBSCRIBE) 呈现 体客户端 A的呈现信息；
3)呈现服务器 102根据订阅授权规则匹配， 如果匹配， 允许订阅； 同时 将该订阅信息发送到呈现 XDMS104中进行信息保存， 同时保存此订阅关系；
4)呈现体客户端 A403委托受委托的呈现体客户端 B或者应用服务器 C404向呈现服务器 102发布 (PUBLISH) 呈现信息； 例如： 老总委托秘书、 用户使用某种业务（如登陆游戏服务器)， 或者点击按钮触发委托发布流程；
5)受委托的呈现体客户端 B或者应用服务器 C404向呈现服务器 102的 委托检査和处理装置 405发布呈现信息， 委托检查和处理装置 405进行如下 操作- a)检查是否为委托发布方式；
b )如果为非委托发布方式， 则进入步骤 f) ; 如果为委托方式， 进入步骤 C ) ;
c)根据委托发布授权规则 (Delegation Publishment Authorization Rule), 判 断是否允许委托发布；
d)根据委托内容授权规则 (Delegation Content Authorization Rule)，判断允 许委托发布哪些内容；
e) 根据委托过滤规则 (Delegation Filter), 将不符合过滤条件的内容过滤 掉；
f)然后将呈现消息发送给呈现信息合成和发布装置；
6)呈现信息合成和发布装置 105可以采用现有的功能单元进行处理（参 考图 6， 呈现信息合成和发布装置 105采用现有的功能单元， 包括呈现信息 合成单元 211、 内容授权规则检査单元 212、 观察体过滤单元 213、 部分通知 处理单元 214和呈现信息发布单元 215);
7 ) 呈现信息合成和发布装置 105 向观察体客户端 101 发送通知 (NOTIFY)。
该实施例中， 委托检査和处理装置 405的各种功能均为可选项。
上述委托检查和处理装置 405对于各种规则的获取， 可以是呈现服务器 102通过 XCAP协议来获得这些规则， 或者如果呈现服务器 102订阅了这些 规则的改变通知， 则当这些规则发生改变时， 呈现 XDMS104会通知呈现服 务器 102; 也可以是委托检查和处理装置 405自己通过 XCAP协议去呈现 XDMS104获取；还可以在呈现服务器 102中设置一个公用的模块，专门用于 从呈现 XDMS104上获取规则， 并提供给其它单元使用； 还可以是上述各种 规则直接存储在呈现服务器 102中； 本领域技术人员应该明白， 本发明中各 个装置或者单元获取相应的规则都可以采用上述方式； 本实施例中需要对新 发布的呈现信息和呈现服务器中现有呈现信息均应用 "委托内容授权规则"、 "过滤条件"， 然后再进行合成。
本实施例中， 应用服务器包括游戏服务器或具有相似功能的服务器， 也 包括即时消息服务器（如 ICQ/MSN服务器)， 用户在游戏服务器中填写需要 发布的消息， 也可以只填写用户标识， 游戏服务器自动将用户标识以及相应 的与游戏相关的呈现信息发送到预定的呈现服务器，如果呈现服务器不唯一， 可以通过用户输入呈现服务器的相关标识进行发送。
上述实施例中描述了以委托方式发布呈现信息的流程，在呈现服务器 102 中， 可以将委托方式与现有技术相结合， 通过委托检查流程进行判断依据哪 种方式进行处理， 用于委托检査的装置接收到呈现信息发布消息， 首先检查 是否为委托发布， 如果为非委托方式， 则按照现有流程处理， 如果是委托方 式， 则从呈现 XDMS104上获取委托授权规则 （包括委托发布授权规则 （是 否允许委托发布)、委托内容授权规则（允许委托发布哪些内容）和委托过滤 规则（符合过滤条件的将被发布， 其它将被丢弃）， 当然， 委托过滤规则也可 以被包含在委托内容授权规则中， 根据实际情况灵活确定）， 根据委托授权规 则发布呈现信息。
关于检查是否为委托发布， 可以采取下列方式：
方法一、 接收消息发布者的用户标识与呈现信息拥有者的用户标识，然 后进行比较， 如果匹配一致， 则为非委托方式， 如果不一致， 则为委托方式。
方法二、 可以在发布消息（消息头或消息体） 中增加表明为委托发布的 字段， 如 "Delegation"字段， 当然， 本领域技术人员能明白， 这个消息放在 发布消息时发送的信息中的任何一处均可以， 只要呈现服务器能够根据预先 设定的协议检测到该消息即可， 例如放在发布的呈现信息中， 而且子段可以 设定为任何一种字段。
下面对执行委托发布授权规则和委托内容授权规则的流程作一个详细的 说明， 参考图 7， 具体流程如下：
1 )委托检查和处理装置 405接收到发布消息后， 从呈现 XDMS104上获取 委托发布授权规则， 根据委托发布授权规则进行匹配；
2)检查发送方（受委托方）在禁止列表中是否有匹配项， 如果有， 则拒 绝发布； 否则， 进入步骤 3 );
3 )检査不在禁止列表中的发送方在委托发布授权规则中是否还有相应的 匹配项， 如果否， 应用呈现服务器的默认策略 （如可以是拒绝或发布所有消 息）； 如果是， 进入步骤 4);
4)检查是否存在多个匹配项， 如果是， 按照选择规则（如优先级）进行 选取； 5)根据获得的匹配项，索引委托发布授权规则中与该匹配项对应的结果， 如果结果不为允许， 进入步骤 6)， 如果结果为允许， 则将该匹配项在委托内 容授权规则中进行再次匹配， 根据再次匹配获得的匹配项， 索引相应的处理 规则 （个人委托内容授权规则或通用委托内容授权规则）迸行处理；
6)如果结果为拒绝， 则拒绝发布；
7)如果结果为需要确认， 则执行确认的处理流程（让委托人进行选择， 可以是选择委托内容授权规则， 如通用委托内容授权规则或某个个人委托内 容授权规则， 也可以是直接选取可以发布的内容选项， 还可以拒绝）；
对于各种规则的制定， 可以根据个人的需求， 灵活掌握， 上面例举的规 则的判断是利用匹配与各个规则相关联的消息字段或标识进行的。
上述本发明涉及到的各个操作步骤及各种规则的制定， 本领域技术人员 根据现有掌握的编程手段就能轻易实施。
为有助于理解， 下面列举几个具体的委托发布授权规则和委托内容授权 规则的例子， 首先要匹配委托发布授权规则， 包括查找禁止列表和匹配记录 表， 匹配记录表包括个人身份匹配（指按照具体的个人的身份（Identity)来 匹配， 例如具体到个人张三、 李四）和通用身份匹配 （指不具体到个人， 可 以采用一个具有公共特性的标识进行匹配判断， 例如 *@163.com)， 根据查找 的结果进行相应的处理， 如果没有查找到匹配的标识， 采用呈现服务器默认 策略处理； 如在禁止列表中查找到匹配标识， 则拒绝发布； 如查找结果对应 的规则为拒绝， 则拒绝发布， 如查找结果对应的规则为允许， 则将该允许对 应的标识在委托内容授权规则中进行匹配， 应用匹配结果所对应的委托内容 授权规则进行处理； 如查找结果对应的规则为确认， 则进行等待确认的处理; 委托内容授权规则包括个人委托内容授权规则和通用委托内容授权规则， 个 人委托内容授权规则与个人标识相对应， 通用委托内容授权规则与通用标识 相对应； 在这些规则中可以制定符合相应规则的信息发布内容或发布范围； 下面举例说明， 假设呈现体为用户李四， 用户李四的相关规则文件如下所示-
1、 禁止列表： [email protected]
2、 匹配记录表 受委托人标识 结果 优先级
zhangsan@ 163.com 允许 1
*@163.com 拒绝 2
3、 委托内容授权规则：
受委托人标识 位置信息 游戏信息
[email protected] 拒绝 允许
*@163.com 允许 拒绝 参照上面的禁止列表、 发布授权规则和内容授权规则， 例举几个用户发 布消息的实例：
1、 如果是 [email protected]帮助李四发送信息， 由于在禁止列表中而被 拒绝；
2、 如果是 [email protected]帮助李四发送信息， 查找发布授权规则的 时候， 个人和通用均有， 匹配结果为个人的优先级高， 且对应规则为允许； 则将个人的标识 "[email protected]"在内容授权规则中进行匹配， 匹配的 结果为釆用 "[email protected]"对应的委托内容授权规则， 允许发布游戏 信息 （在这里采用精度匹配方式， 如果在委托内容授权规则中没有 [email protected]标识， 则采用标识 "*@163.com"对应的规则进行处理， 即只允许发位置信息）；
3、 如果是 [email protected]帮助李四发送信息， 查找发布授权规则的 时候， 匹配结果为通用标识， 规则对应为拒绝， 则拒绝发送；
4、 如果是 [email protected]帮助李四发送信息， 匹配标识为个人标识， 对应规则为允许； 将该个人标识 [email protected]在委托内容中进行匹配， 匹配的结果为 " *@163.com"， 对应的规则为允许发布位置信息；
5、 如果是 [email protected]帮助李四发送信息， 由于在委托发布授权 规则中 （禁止列表和匹配记录表）没有匹配的标识， 根据呈现服务器的默认 策略， 可以为拒绝或者确认；
6、如果是 [email protected]帮助李四发送信息， 有匹配的标识， 但是该 标识对应的规则为确认， 则进行确认的处理过程。
而且还可以在委托发布授权规则中限定发布时间和次数， 如有效期为每 天 8:00〜18:00， 次数指定 100次， 100次以后订阅无效， 不再发布， 需要重新 订阅， 或者续费订阅等等。
针对本发明的方法，下面描述本发明的呈现体客户端的结构和相应流程- 本发明的呈现体客户端中增加的委托发布处理模块， 呈现体客户端执行 如下处理流程；
1 )询问呈现信息发布实体是否采用委托发布；
2)如果是委托发布， 发布消息中指明为委托发布方式， 如在发布消息头 中增加委托发布字段；
3 )如果为委托发布， 发布消息中可以不添加字段， 而是采用发送发布者 的用户标识与呈现信息拥有者的用户标识， 由呈现服务器进行判断， 也可以 添加表示非委托发布方式的字段。
