具体实施方式 本发明提供了查询用户信息的方法, 本发明的核心为: 设置一个搜索 代理, 对业务引擎服务器或客户端发送的查询请求进行处理后, 转发给相 应的 XDM服务器,并获取相应的呈现信息, 然后将呈现信息和 XDM服务器 返回的查询结果进行整合处理后, 返回业务引擎服务器或客户端。 下面首先描述应用本发明方法的通信系统 , 该通信系统的结构如图 2 所示, 包括客户端、 聚合代理、 XDM服务器、 呈现服务器和搜索代理。
所述搜索代理用于接收聚合代理转发的客户端发送的包含查询条件的 查询请求, 并将查询请求消息转发给存储用户信息或群组信息的 XDM服务 器; 接收 XDM服务器返回的查询结果, 查询结果中包括满足查询条件的用 户 URI; 向呈现服务器订阅所述查询结果中包含的用户 URI的呈现信息, 并 接收呈现服务器返回的呈现信息; 将呈现服务器返回的呈现信息和 XDM服 务器返回的查询结果进行整合后, 通过聚合代理发送给客户端。 聚合代理用于接收客户端发送的查询请求, 并将该请求转发给搜索代 理, 将搜索代理传递过来的处理结果返回给客户端, 客户端还可以通过聚 合代理对 XDM服务器中存储的 XML文档进行管理。
XDM服务器包括呈现 XDM服务器等业务引擎 XDM服务器和共享 XDM服务器。 XDM服务器用于存储和管理各种业务引擎的 ML文档, 并 向搜索代理提供所查询的 XML文档信息。 共享 XDM服务器用于存储和管理各种业务引擎共享的 XML数据。共享 XDM服务器包括共享列表 XDM服务器、 共享群组 XDM服务器和共享用户 信息 XDM服务器三种服务器。 共享列表 XDM服务器用于存储共享的 URI列表信息, 包括列表名、 列 表包含的 U I等信息; 共享群组 XDM服务器用于存储共享的群组信息, 包 括群组标识 URL 组员 URI、 群组名和描述、 群组策略等信息, 包括 PoC群 组 XDM服务器和 IM群组 XDM服务器等; 共享用户信息 XDM服务器用于存 储共享的用户信息, 包括用户标识 URI、 姓名、 年龄和性别等信息。 为叙 述方便, 本文将用户标识 URI、 群组成员用户的 URI等统称为用户 URL 呈现服务器用于接收、 存储和分发包括用户是否在线等用户的呈现信 息。 呈现 XDM服务器用于存储用户的授权规则等信息。 客户端用于向聚合代理发出查询请求, 接收并显示聚合代理返回的处 理结果,客户端还可以向聚合代理发送操作 XDM服务器中存储的 XML文档 的请求。 在上述通信系统中查询用户信息的方法的具体处理流程如图 3所示,包 括如下步骤: 步骤 3-1: 聚合代理将客户端发出的查询请求转发给搜索代理。 在本发明中客户端可以通过 HTTP POST方法向聚合代理发出查询请 求。 HTTP POST消息体中包含对应搜索代理的应用唯一标识 AUID和查询表 达式。 与目前的 XCAH^、议处理一致, 对查询请求操作新设定一个 AUID ( XCAP应用唯一标识), 如 "SearchRequest" ,客户端发送的包含该 AUID 的 XCAP消息被聚合代理路由转发到搜索代理。 目前现有技术中指定已有 AUID的 XCAP操作请求, 如创建或修改某个 XDM服务器上 XML文档, 则 被聚合代理直接路由到相应的 XDM服务器进行处理。 步骤 3-2: 搜索代理对接收到的请求进行处理后, 向 XDM服务器和呈 现服务器等请求获取相应的信息。 搜索代理接收到聚合代理转发的查询请求后 , 对该请求进行相应的处 理。 通常每个 XML文档都对应一个授权规则文档, 记录该 XML文档的读取 或查询、 修改和删除等操作的权限, 以及哪些用户可以执行哪些操作。 搜 索代理可以根据发送查询请求的用户的 URI, 通过 XCAP协议访问 XDM服 务器, 获取该用户的授权规则等信息, 即获取该用户有读取或查询权限的 XML文档列表信息, 然后, 产生相应的查询消息, 发送给相应的 XDM服务 器。 或者由 XDM服务器直接处理查询请求, 对查询请求进行鉴权, 确定是 否可以查询以及该用户有读取或查询权限的 XML文档列表信息, 然后在该 列表的文档中进行查询, 并将最终的查询结果返回给搜索代理, 这样虽然 减少了交互, 但是需要 XDM服务器执行大量的鉴权处理。
XDM服务器根据接收到的搜索代理发送的查询消息后,解析该查询消 息,在所述用户有读取或查询权限的 XML文档列表中查询相应的 XML文档 信息。如果所述用户有读取或查询权限的 XML文档列表中一个 XML文档的 授权规则文档虽然设置了允许该用户的 URI进行读取操作, 但是并不是允 许读取或查询该 XML文档的全部, 而是只允许读取或查询部分内容。 则 XDM服务器在查询信息时, 还要根据授权规则文档信息确定该 URI可以获 取的内容部分, 并在其中查询信息。 另外搜索代理可以在用户的一次查询中向多个服务器获取所需的信 息, 对于从多个服务器获取所需的信息要进行并集操作的, 可以采用并发 的方式向多个服务器发送查询请求; 对于要以以前一次的查询结果作为后 一次的查询条件, 则需要顺序执行查询, 如客户端查询包含指定 υτ 的群 组的组员用户信息, 则搜索代理需要先到存储群组信息的 XDM服务器获取 到包含指定 URI的群组, 以及群组包含的组员的 URI, 然后搜索代理再到存 储用户信息的 XDM服务器查询上述组员 URI的用户信息。 搜索代理接收 XDM服务器返回的查询结果, 查询结果中包括满足查询 条件的用户 UR [或群组成员用户的 U I,搜索代理向呈现服务器订阅查询结 果中包含的用户 URI的呈现信息, 呈现服务器将呈现信息返回给搜索代理。 呈现服务器根据每个所述用户 URI对应的授权规则文档, 确定搜索代 理是否被允许获取所订阅的呈现信息, 然后将允许搜索代理获取的呈现信 息返回给搜索代理。 可以预设一个代表搜索代理实体的搜索代理 URI, 在 呈现 XDM服务器里的用户的授权规则文档中为搜索代理 U I对应设置允许 搜索代理订阅的呈现信息。 也可以采取搜索代理为发送查询请求的客户端 所对应的 IIRI向呈现服务器订阅所述查询结果中包含的 URI的呈现信息,呈 现服务器根据每个用户 URI的授权规则文档, 确定发送查询请求的客户端 所对应的 U I是否被允许获取呈现信息, 然后将允许获取的呈现信息返回 给搜索代理。 搜索代理发送的订阅请求一般为一次性订阅, 即在 SIP订阅消 息中指定过期时间为零即可。 另外呈现服务器接收到搜索代理发送的订阅 请求后, 如果检测到所订阅用户 URI的授权规则中要呈现体用户进行确认 才可以订阅该用户的呈现信息, 则呈现服务器拒绝为搜索代理订阅该用户 的呈现信息, 如此可避免在查询过程中产生大量的确认通知, 而且如果等 呈现体用户确认后再发送呈现信息会导致查询响应太慢。 步驟 3-3: 搜索代理对 XDM服务器、 呈现服务器等返回的信息进行整 合处理, 通过聚合代理将处理结果返回给客户端。 整合处理的具体方法包括:
1、 搜索代理对多个 XDM服务器返回的查询结果进行集合运算。 可以 联合或合并查询结果, 即对查询结果进行并集(UNION )操作; 还可以根 据查询请求中的条件对查询结果进行交集等操作。比如,用户希望获取 PoC 业务或 IM业务中包含指定成员 U I的群组信息, 则搜索代理可以对分别从 PoC业务的 XDM服务器和 IM业务的 XDM服务器上获得的包含指定成员 U I的群组信息进行并集运算;如果是用户希望获取包含指定成员 UR [的群 组即在 PoC业务又在 IM业务中, 则要进行交集运算。
2、 搜索代理用后一次获取的信息对前一次的查询结果进行过滤处理。 如客户端查询满足一定限定条件(如年龄、 性别或地区等)的用户的信息, 并限定为当前在线的用户。 这样搜索代理首先从 XDM服务器上获取满足限 定条件的用户信息, 然后再从呈现服务器上获取这些用户的是否在线的呈 现信息, 并根据呈现服务器返回的结果将不在线的用户过滤掉, 只将在线 用户的用户信息返回给客户端。
3、 搜索代理将查询结果进行连接处理, 即将多个查询结果进行关联。 一般根据用户 URI进行关联, 如将 XDM服务器返回的用户信息和从呈现服 务器上获取的呈现信息进行关联, 将对应同一个用户 URI的用户信息和呈 现信息整合为一条记录, 当然在关联的同时还可以进行上述的过滤处理。 搜索代理将整合处理后的查询结果通过聚合代理发送 έ合客户端。 本发明提供了查询用户信息的方法的三个实施例, 下面分别介绍该三 个实施例。 实施例 1: 客户端需要搜索查询满足限定条件的在线用户。 现有技术中呈现服务器、 呈现 XDM服务器、 观察者客户端、 呈现体客 户端的組网示意图如图 4所示, 现有的呈现服务器是基于订阅 /通知机制的, 没有提供查询机制, 也不是一个 XCAP服务器, 即不提供通过 XCAP协议访 问呈现信息的接口。 其中呈现体客户端发布呈现信息到呈现服务器 , 观察 者客户端订阅呈现体的呈现信息, 呈现服务器接收并分发呈现信息给观察 者客户端, 另外实际应用中用户终端如手机、 计算机上的客户端可以同时 作为 XDM客户端和呈现体客户端, 以及观察者客户端。 如果搜索代理直接 向呈现服务器通过非订阅 /通知机制的方式来请求查询获取呈现信息, 则需 要在搜索代理和呈现服务器之间新增接口协议以及进行相应的处理来实 现, 这将增加搜索代理和呈现服务器的复杂性。 当然将呈现服务器作为 XCAP服务器, 搜索代理通过 XCAP协议访问呈现信息, 也是一种可行的方 案, 毕竟搜索代理可以象访问其他 XDM服务器一样访问呈现服务器, 不用 多增加新的功能, 目前的呈现服务器只是作为 XCAP客户端,可以访问和操 作呈现 XDM服务器中 XML文档。 为解决上述问题, 可设置了一个呈现信息 XDM服务器, 在该服务器上 同步保存呈现信息和用户的授权规则等信息, 即当呈现服务器上的呈现信 息或呈现 XDM服务器上的授权规则信息发生变化时, 就同时更新呈现信息 XDM服务器上的信息,呈现服务器可以通过 XCAP或 SIP协议等向呈现信息 XDM服务器同步信息。 呈现信息 XDM服务器、 呈现服务器、 呈现 XDM服 务器的组网示意图如图 5所示。 参见图 5, 一种查询用户信息的系统, 包括客户端、 XDM服务器以及 提供 XCAP服务且用于存放呈现信息的服务器, 该系统还包括: 搜索代理, 其中, 搜索代理接收聚合代理转发的来自客户端的包含查询奈件的查询请 求, 并将查询请求消息转发给存放用户信息的 XDM服务器和所述存放呈现 信息的服务器; 接收服务器返回的查询结果, 查询结果中包括满足查询条 件的用户信息和呈现信息; 将所述用户信息和呈现信息进行整合后, 通过 聚合代理发送给客户端。 存放呈现信息的服务器为呈现服务器, 或呈现信息 XDM服务器; 该呈 现信息 XDM服务器同步呈现服务器中用户的呈现信息。 下面说明一下该实施例的具体的查询流程:
1、 客户端发送 HTTP POST查询请求给聚合代理, 查询表达式中包括: 用户信息条件为 "用户性别 =女, 地区 =深圳, 运动爱好=网球" , 以及呈现信息为在线的条件, 同时指定了返回的查询结果还要包含用户 υτ 、 用户昵称等用户信息。
2、 聚合代理将该请求转发给搜索代理,搜索代理首先向共享用户信息 XDM服务器查询满足查询表达式中用户信息条件的 XML文档信息。一个包 含用户信息的 ML文档内容举例如下:
<?xml version="1.0" encoding="UTF-8"?> <user-profile entity="sunqian@msn.com">
<nickname>Aaron</nickname>
<gender>male</ gender>
<city>Shenzhen</city>
<hobby>tennis</hobby>
<e-mail>mailto:sunqian@huawei.com</e-mail> </user-profile> 通常在共享用户信息 XDM服务器中存储的每个用户的用户信息 XML 文档都有对应的授权规则文档, 包括了其他用户访问该文档中用户信息的 权限如读或查询、 写、 改等才乘作, 授权规则文档举例如下:
<?xml version:" 1.0" encoding="UTF-8"?>
<ruleset entit ="sunqian@msn.com">
<rule id="l">
<conditions><identity> <domain domain="msn.com"/> </identity></ conditions
<actions>search</actions>
<transformations><provide-all-profile/></transformations> </rule> </ruleset> 上述" sunqian@msn.com"的授权规则 ruleset定义的一个规则 rule描述了 对域 domain为 "msn.com"的用户都有查询 search权限 , 允许查询的范围为全 部用户信息 provide-all-profile。 于是, 共享用户信息 XDM服务器在接收到搜索代理发送的查询消息 后, 先获取发送查询请求的用户 URI有读或查询权限的用户信息 XML文档 列表, 然后在该列表中根据条件 "用户性别 =女, 地区 =深圳, 运动爱好 =网球" 进行查询, 并将满足条件的用户信息, 包括用户 URI、 用户昵称 等返回给搜索代理。 另外, 查询条件里已经有的信息如用户性別就没有必 要返回了。 上述方法要求 XDM服务器根据查询条件进行处理, 这样如果查询条件 比较复杂,会影响 DM服务器的性能,可能会导致其他的 XDM操作响应时 间变慢。 可以采用另外一种方法: 首先搜索代理从 XDM服务器获取发送查询请求的用户 URI有读或查询 权限的 XML文档列表,然后由搜索代理对每个 XML文档发送单独的查询请 求, 最后搜索代理再将每次从 XDM服务器获取的查询结果整合在一起。 这 种方法只需要 XDM服务器执行简单的单个 ML文档信息的查询即可, 即 XDM服务器只处理简单的 HTTP GET操作即可, 对 DM服务器性能影响较 小。
3、搜索代理获取包含用户信息的响应消息后, 将包含发送查询请求用 户的 URI以及用户信息对应 U I的查询请求发给存储呈现信息的服务器,如 呈现服务器或呈现信息 XDM服务器, 存储呈现信息的服务器获取用户信息 对应 U I的授权规则,判断发送查询请求用户的 URI是否有权限获取是否在 线 STATUS的呈现信息, 然后对有权限的用户查询其呈现信息, 并将是否 在线的信息返回给搜索代理。 呈现信息 XDM服务器中的呈现信息可以是呈 现服务器主动同步过来的, 如使用 XCAP协议将呈现信息同步到呈现信息 XDM服务器中的 XML文档中 , 或者呈现信息 XDM服务器通过 SIP订阅了呈 现服务器中用户的呈现信息, 当被订阅的用户的呈现信息发生变化时, 呈 现服务器通过 SIP通知将更新的呈现信息发送给呈现信息 XDM服务器, 呈 现信息 XDM服务器再更新本地保存的呈现信息。 也可以采用在查询时呈现信息 XDM服务器才去呈现服务器获取呈现 信息。 搜索代理将查询请求发给呈现信息 XDM服务器, 查询请求中包含了 要获取呈现信息的用户 URI, 呈现信息 XDM服务器代理发送查询请求的用 户对这些 URI向呈现服务器发起一次性订阅 (FETCH ) , 呈现服务器依据 这些 URI对应的授权规则发送查询请求的用户进行鉴权, 然后将呈现信息 通知(NOTIFY )返回给呈现信息 XDM服务器, 呈现信息 XDM服务器再将 呈现信息返回给搜索代理。这种方法符合目前呈现业务的鉴权机制以及 SIP 订阅 /通知机制, 对呈现服务器不需要进行任何改动。
4、 搜索代理将用户信息和呈现信息进行整合后, 一起返回给客户端。 整合的具体方法可以为: 以查询的呈现信息的结果对从 XDM服务器的查询 结果进行过滤处理, 即只将呈现信息为在线的用户 URI对应的 XDM服务器 返回查询结果转发给客户端。 上述实施例 1对应的消息交互流程图如图 6所示。 因为呈现服务器中呈现信息内容非常多, 不仅包括是否在线这种基本 的状态信息, 还可以包括位置, 情绪, 活动等丰富的信息, 另外也不是所 有用户都希望或被允许提供呈现信息的查询, 呈现服务器可以根据用户或 者系统的设置将部分用户的部分呈现信息同步到共享用户信息 XDM服务 器或呈现信息 XDM服务器上, 而不是全部。 另外实际上也可以直接由共享用户信息 XDM服务器同步呈现服务器 中的呈现信息, 这样对同时查询用户信息和呈现信息来说实现更简单, 搜 索代理直接在共享用户信息 XDM服务器即可获得用户信息和相应的呈现 信息, 不必再去其他服务器上去查询了。 但是这样与共享用户信息 XDM服 务器用来存储简单的静态用户信息的设计思想相违背, 增加了其复杂性。 可以采用折中的方案, 即在共享用户信息 XDIvO良务器中的用户信息中增加 一个 "是否在线" 的字段, 该字段的值由呈现服务器根据用户是否在线的 呈现信息进行同步, 当用户的在线状态发生变化时, 呈现服务器可以通过 SIP或 XCAP协议修改共享用户信息 XDM服务器中的信息 ,或者共享用户信 息 XDM服务器可以订阅用户是否在线的呈现信息。 这样需要同步的信息很 少, 而且在查询在线用户的信息时, 搜索代理就不用再去访问呈现服务器 了。 基于上述折中的方案,存在一种查询用户信息的系统, 其包括客户端、 聚合代理、 存储用户信息的 XDM服务器以及呈现服务器, 该系统还包括: 搜索代理, 其中, 存储用户信息的 XDM服务器用于向呈现服务器订阅用户的呈现信息; 根据接收到的来自呈现服务器的通知进行呈现信息的同步更新处理; 根据 接收到的查询请求中的限定条件确定查询结果, 并返回。 其中, 存储用户 信息的 XDM服务器为共享 XDM服务器, 所述存储用户信息的 XDM服务器 向呈现服务器订阅用户的呈现信息为是否在线的呈现信息。 呈现服务器用于在所述 XDM服务器订阅的呈现信息发生改变时发送 相应的通知给所述 XDM服务器。 搜索代理用于接收来自客户端经聚合代理转发的查询请求, 并将查询 请求消息转发给存储用户信息的 XDM服务器, 所述查询请求中的限定条件 包含有对用户呈现信息的限定条件; 将接收到的所述 XDM服务器返回的查 询结果通过聚合代理转发给客户端。 其中, 对用户呈现信息的限定条件为 用户呈现信息为在线状态。 实施例 2: 客户端先获取到 XDM服务器中的用户信息, 再从呈现服务 器获取相应的呈现信息。 该实施例的组网示意图如图 7所示。 在 XDM服务器中存储有共享群组信息, 该共享群組信息通过如下的 XML文档来表示:
<?xml version-" 1.0" encoding="UTF-8"?>
<group>
<list-service uri="sip :meetingroom-F 1 -7-A08 @huawei. com"> <display-name>regular meeting</ display-name> <subj ect> Application and Software Dept<subject> <list>
<entry uri="tel:l 30489070337> <entry uri="sip:sunqian@huawei.com"> <display-name>Sun Qian</display-name> </entry> </list> <ruleset><rule id="l"> <conditions><identity> <domain domain="huawei.com'7> </identity></ conditions>
<actions><search-handling>allow</search-handling></actions>
<transformations/>
</rule></ruleset>
</list-service>
</group> 所述共享群組信息包括: 群组 URI、 display-name (显示名称)、 subject (标题) 、 list (组员列表)和包含的群组成员的 U I信息等, 以及授杈规 则 ruleset , 该授权规则给出的一个规则 rule , 设置了允许属于域 domain="huawei.com"的用户可以查询 search该组。 对于允许哪些 URI查询 search该组也可以定义在该 XML文档对应的单独的授权规则文档中。 客户端接收到用户输入的包含查询条件的查询指令后, 如指定的查询 条件为群组的主题 subject包含字符串 "Application and Software" , 以及指 定要返回的群组信息包括群組 URI、 名称等, 并且要求返回群组成员的呈 现信息如是否在线等。客户端先发送查询请求以获取 XDM服务器中的相应 信息, 聚合代理接到上述请求后, 将该查询请求转发给搜索代理, 由搜索 代理从相应的 DM服务器如共享群组 XDM服务器中获取信息并经聚合代 理返回给客户端, 客户端根据返回信息中查询到的用户的 URI再向呈现服 务器发送订阅呈现信息的请求, 呈现服务器将呈现信息返回给客户端, 客 户端将搜索代理返回的查询结果和呈现信息进行整合后再显示给用户。 对 于搜索代理向 XDM服务器进行查询的具体过程以及整合的方法在上述实 施例 1中已有详细描述, 此处不再赘述。 此实施例的关键技术在于客户端自动将用户的一次查询分为两次进 行, 首先通过搜索代理查询获取到除呈现信息之外的用户信息, 然后再去 呈现服务器订阅相应的呈现信息, 最后整合后再显示给用户。 当然也可以 先将搜索代理返回的查询结果先显示出来, 然后客户端再去自动订阅查询 结果中包含的用户的呈现信息, 客户端每接收到一个呈现服务器返回的包 含呈现信息的通知, 就刷新一下显示的内容, 将呈现信息与相应用户的其 他用户信息关联显示, 如在同一行进行显示。
参见图 7, —种查询用户信息的系统, 包括客户端、 DM服务器以及 呈现服务器, 该系统还包括: 搜索代理, 其中,
客户端用于接收到用户输入的包含查询条件的查询指令后, 通过聚合 代理向搜索代理发送查询请求以获取 XDM服务器中的相应信息; 当接收 到搜索代理返回的查询结果后, 向呈现服务器订阅所述查询结果中包含的 用户 URI的呈现信息; 将所述呈现服务器返回的呈现信息和所述搜索代理 返回的查询结果进行整合后显示给用户。
呈现服务器用于将所述客户端订阅的呈现信息返回给客户端。
搜索代理用于将接收到的查询请求, 转发给相应的 XDM服务器; 接 收所述 XDM服务器返回的查询结果, 然后通过聚合代理转发给客户端, 所述查询结果中包括查询到的用户 URL 如果用户指定的查询限定条件太宽,可能搜索代理从 XDM服务器上获 取的查询结果会 ί艮多, 比如用户查询指定性别和地区的用户信息, 则可能 会返回成千上万条记录, 这样不宜将所有的查询结果一次性返回给用户, 另外如果查询代理緩存全部的查询结果,然后根据客户端的请求分批次(如 批次 20条记录)返回, 这样查询代理的负担较大, 而用户往往可能只获取 前几批结果后就不再需要剩余的查询结果了。 可以釆用如下方案来解决: 在客户端发送查询请求时, 在查询请求中指定批次号 η (首次发送查询请求 η等于 1 ) , 当搜索代理向存储用户信息的 XDM服务去查询时, 根据所述批 次号以及预先设定的每批次的数量 m (也可以在查询请求中设定每批次的 数量) , 确定要请求获取第 (n - 1 ) x m + 1至第 n x m条用户信息记录, 其 中 XDM服务器中的用户信息记录通常可以以用户的 URI等来进行索引, XDM服务器向搜索代理返回所请求的查询结果, 搜索代理再转发给客户 端, 当客户端请求获取下一批时, 指定批次自动加 1 , 则搜索代理继续向 XDM服务器请求第 n x m + 1至第 (n + 1 ) < m条用户信息记录。 这样实际 上相当于对用户的查询结果进行了数量上的限制, 避免一次返回大量的查 询结果, 而且通过指定批次的不同, 保证每次返回给客户端的查询结果也 不重复。 实施例 3·. 描述业务引擎服务器与搜索代理之间的交互。该实施例的组 网示意图如图 8所示。 在本发明中,如 Presence, PoC、 即时消息和位置等业务引擎的服务器, 可以向搜索代理发送查询请求, 获取 XDM服务器中满足条件的用户信息。 同时, 搜索代理也可以从业务引擎服务器获取业务引擎中用户的相关业务 信息(如从呈现服务器获取呈现信息, 从位置服务器获取位置信息等) , 作为查询结果的一部分返回给客户端。 而现有技术中, 业务引擎服务器只能通过 XCAP协议进行修改、 删除, 读取 XDM服务器中的单个文档中的信息。 因此, 本发明中业务引擎可以支 持更加复杂的业务请求。 如在位置业务中, 位置服务器接收到一个定位请 求, 该请求中指定了要获取属于指定群组并且为指定性别的在线用户的位 置, 位置服务器则先向搜索代理发送查询请求, 查询属于指定群组并且为 指定性别的在线用户的 URI, 搜索代理接收到查询请求后先向存放群组信 息 XDM服务器获取指定群組所包含的组员用户的 URI, 再向存放用户信息 的 XDM服务器获取组员的用户信息, 此实施例采用存放用户信息的 XDM 服务器同步呈现服务器上用户是否在线的呈现信息, 存放用户信息的 XDM 服务器将满足指定性别并且在线的用户 U I返回给位置服务器, 位置服务 器再将这些用户的位置信息返回给请求者。 与客户端访问搜索代理不同的 是, 业务引擎服务器不用通过聚合代理就可以访问搜索代理。
