本实施例通过获取相对评估条件, 该相对评估条件中指明了相对条件评 估的参照对象, 进而将参照对象的相关信息作为评估的依据, 实现了可以根 据参照对象的状态来进行相对条件评估; 进一步的, 本实施例可以将预先定 义的相对评估条件存储在特定的存储位置, 可以不在评估请求消息中携带该 相对评估条件, 提高了评估效率。
图 2为本发明实施例二实现相对条件评估的方法的信令流程图, 本实施 例以 CBUS业务为例, 其中所涉及的设备包括 CBUS客户端、 CBUS服务器 以及相关的业务引擎, 如图 2所示, 本实施例具体包括:
步骤 201、 CBUS客户端向 CBUS服务器发送评估请求消息, 该评估请 求消息中包括相对评估条件以及相对评估条件中指明的参照对象, 另外还可 以包括评估对象和 /或评估设置, 评估对象和评估设置可以为可选信息;
其中, 相对评估条件可以分为以下两种情况: 一是仅包括相对条件; 二 是为相对条件与评估对象自身条件的组合。 进一步的, 由于 CBUS服务器主 要根据评估对象的位置 (location )信息、 呈现(presence )信息以及在共享 XDMS中的信息进行评估, 因此相对评估条件可以通过与上述三种信息中的 一种或多种信息对应的部分来表示。 另外, 相对评估条件中表明了 CBUS服 务器应当将评估对象的信息与参照对象的信息进行比较, 因此, 相对评估条 件指明了参照对象, 即参照对象包括在相对评估条件中。
参照对象可以为评估请求发起者自身, 也可以为评估请求发起者指定的 他人; 参照对象可以为一个或多个; 在评估过程中, 参照对象可以是固定的, 也可以发生改变, 如 CBUS服务器根据 CBUS客户端的预先设置在不同的条 件下动态选取不同的参照对象。
评估对象可以为单个用户、 多个用户(如某个群组)或以群组为单位(如 多个群组) , CBUS 业务支持群组选择的功能, 可以对评估请求者指定的多 个群组进行评估, 选择出满足相对评估条件的群组。
评估设置主要包括评估方式, 如一次评估、 实时评估、 结束评估 (评估 到满足相对评估条件者即结束评估)等方式。 另外, CBUS还支持 CBUS客 户端根据自身需求设置 CBUS服务器返回评估结果的数量的上下限, 例如: 如果当前满足相对评估条件者未达到下限, 则 CBUS服务器持续评估, 直至 达到下限, 返回评估结果, 并且 CBUS服务器返回的结果数量不超过上限。
本步骤中 CBUS 客户端可以通过策略评估执行与管理请求即付接口 ( Policy Evaluation, Enforcement and Management Callable Interface , 以下简 称: PEM-1 )接口向 CBUS服务器发送评估请求消息, 进一步的, 本实施例 中可以通过 PEM-1接口实现 CBUS客户端和 CBUS服务器之间的交互。具体 地说, 策略评估执行与管理 ( Policy Evaluation, Enforcement and Management, 以下简称: PEEM )是一种通过评估、 执行、 管理终端用户的偏好设置、 运营 商制定、 服务提供者、 应用开发商指定的策略, 从而实现资源的保护和管理 的框架, PEEM中定义了用于策略评估的接口 PEM-1。 在通过 PEM-1接口向 PEEM请求策略处理资源时, 由于各种资源的差异性, 则对应的策略也有所 不同, 从而导致 PEM-1输入信息与输出信息也各不相同, 则输入的参数与输 出的参数也不相同。 由于 PEM-1是一个通用的接口, 不可能对不同的策略制 定不同的独立的接口, 因此可以通过 PEM-1模板来解决这个问题——即规范 请求与响应的结构。 PEM-1模板定义了希望评估请求者提供哪些输入 PEM-1 参数用于策略的处理, 以及策略处理以后可能会生成哪些输出 PEM-1参数给 评估请求者, 即定义了基本的输入与输出参数, 并且支持根据特定需求进行 参数的扩展。 作为可选的方式, 本实施例可以重用该接口, 通过扩展 PEM-1 接口的输入输出模板参数,来实现 CBUS客户端与 CBUS服务器之间的交互。 步骤 202、 CBUS服务器解析评估请求消息, 获得相对评估条件以及相对 评估条件中指明的参照对象, 还可以获得评估对象、 评估设置;
可选地, 步骤 201的评估请求消息中可以包括引用路径信息, 该引用路 径信息指示了相对评估条件的存储位置, 则在步骤 201之前包括将相对评估 条件存储在该存储位置; 步骤 202具体为: 从该引用路径信息所对应的存储 位置获取相对评估条件以及相对评估条件中指明的参照对象, 可选的, 还可以 获取评估对象、 评估设置。 具体地说, 相对评估条件、 评估对象和 /或评估设 置可以预先定义, 用户或应用将预先定义的相对评估条件、 评估对象和 /或评 估设置存储在特定的存储位置, 例如共享 XDMS, 或 CBUS服务器内部的存 储空间,通过这种方式,用户或应用在发起评估请求时,只需要指明引用路径。
步骤 203、 CBUS 服务器获取评估对象的相关信息和参照对象的相关信 息, 具体包括:
步骤 2031、 CBUS服务器向信息源 (本实施例具体为业务引擎)发送获 取评估对象和参照对象的相关信息的请求消息; 其中可以携带评估请求发起 者的身份信息;
本发明实施例的业务引擎包括但不仅限于位置引擎、 呈现引擎和共享 XDMS引擎。
进一步的, CBUS 服务器根据相对评估条件可以从同一信息源获取评估 对象和参照对象的相关信息, 也可以从不同的信息源获取评估对象和参照对 象的相关信息。
步骤 2032、 业务引擎向 CBUS服务器返回评估对象和参照对象的相关信 息;
在步骤 2031和步骤 2032之间还可以包括: 业务引擎根据评估请求发起 者的身份信息,对评估请求发起者进行身份验证。具体地说,在业务引擎(如: 呈现引擎或位置引擎)接收到 CBUS服务器发送的获取评估对象和参照对象 的相关信息的请求消息时, 可以对评估请求发起者 (本实施例为 CBUS客户 端 )进行鉴权; 若 CBUS服务器通过 SIP协议实现与业务引擎之间的交互, 如通过 SIP订阅通知机制获取呈现信息, 则可以在发送至该业务引擎的请求 消息中携带 Identity以及 Identity-Info两个头字段, 来表示评估请求发起者的 身份信息, 其中, Identity字段是用于身份验证的签名, Identity-Info是签名 者证书的引用; 若 CBUS服务器通过其他协议实现与业务引擎之间的交互, 如通过 HTTP协议与位置引擎交互获取位置信息, 则可以通过在该协议中扩 展与 SIP协议中的 Identity以及 Identity-Info作用相同的字段, 来携带评估请 求发起者的身份信息。 根据上述评估请求发起者的身份信息, 业务引擎对评 估请求发起者进行身份验证。
步骤 204、 CBUS服务器根据相对评估条件和评估设置,将评估对象的相 关信息和参照对象的相关信息进行比较, 得出评估结果;
步骤 205、 CBUS服务器向 CBUS客户端返回评估结果。
上述实施例中相对评估条件包括相对条件, 若相对评估条件为相对条件 和评估对象自身条件的组合, 即相对评估条件包括第一评估条件和第二评估 条件, 其中第一评估条件为相对条件, 第二评估条件为评估对象自身条件, 其中评估对象自身条件中指明评估对象的某项状态满足固定值, 则步骤 204 和步骤 205可以具体包括:
CBUS 服务器根据相对条件, 将评估对象的相关信息和参照对象的相关 信息进行比较, 得出满足相对条件的第一评估对象;
CBUS 服务器从相关信息源 (本实施例具体为业务引擎)获取的第一评 估对象的相关信息, 例如从呈现服务器获取第一评估对象的呈现信息等;
CBUS 服务器将第一评估对象的相关信息与评估对象自身条件即第二评 估条件进行比较, 进一步筛选出满足评估对象自身条件的第二评估对象; CBUS服务器将第二评估对象作为评估结果, 返回给 CBUS客户端。 本实施例也可以首先陣选出满足评估对象自身条件即第二评估条件的评 估对象, 然后进一步陣选满足相对条件即第一评估条件的评估对象, 也就是 说, 对于相对评估条件为相对条件和评估对象自身条件的组合的情况, 本实 施例对两种条件进行评估顺序不作限定。
本实施例中, 评估请求消息中指定了参照对象、 相对评估条件、 也可以 进一步包括评估设置以及评估对象, 从业务引擎获取的参照对象的相关信息 作为评估的依据, 在相对评估条件为相对条件时, 则无需评估请求者指定评 估对象的某项状态满足某固定值, 实现了根据参照对象的状态来评估; 在相 对评估条件为相对条件和评估对象自身条件的组合时, 可依次陣选满足这两 个条件的评估对象, 使得相对条件评估的实现更具灵活性; 进一步的, 本实 请求消息中携带该相对评估条件 , 评估效率更高。
本发明实施例三实现相对条件评估的方法与上述实施例二的区别在于, 步骤 201中 CBUS服务器接收的评估请求消息中不包括评估对象。 本实施例 可以分为以下几种情况:
第一种情况: 相对评估条件仅包括相对条件, 且参照对象的相关信息和 需要搜索的评估对象(搜索对象) 的相关信息在同一信息源获取, 具体见图 3 , 图 3 为本发明实施例三实现相对条件评估的方法第一种情况的信令流程 图。 其中, 步骤 201可以替换为步骤 201A、 CBUS客户端向 CBUS服务器发 送包括相对评估条件的评估请求消息, 步骤 203和步骤 204可以替换为: 步骤 203A、 CBUS服务器向信息源 (具体为业务引擎)发送携带有相对 评估条件和参照对象的搜索请求消息; 步骤 203B、 业务引擎查询参照对象的 相关信息, 根据参照对象的相关信息和相对评估条件, 搜索满足相对评估条 件的评估对象; 步骤 203C、将满足相对评估条件的评估对象返回给 CBUS服 务器; 步骤 203D、 CBUS服务器接收返回的满足相对评估条件的评估对象, 将其作为评估结果。
第二种情况: 若相对评估条件仅包括相对条件, 且参照对象的相关信息和 搜索对象的相关信息在不同信息源获取, 则步骤 203和步骤 204可以替换为: CBUS 服务器从第一信息源获取参照对象的相关信息; CBUS服务器向 第二信息源发送携带有相对评估条件和参照对象的相关信息的搜索请求消 息; 第二信息源根据相对评估条件和参照对象的相关信息, 搜索满足相对评 估条件的评估对象, 并返回给 CBUS服务器; CBUS服务器接收返回的满足 相对评估条件的评估对象, 将其作为评估结果。
第三种情况: 若相对评估条件为相对条件(第一评估条件)和评估对象 自身条件(第二评估条件) 的组合, 第二评估条件指明评估对象的条件满足 某固定值,且参照对象的相关信息和搜索对象的相关信息在同一信息源获取, 本实施例还可以在业务引擎中搜索满足相对条件的评估对象, 再利用服务器 进一步筛选出满足搜索对象自身条件的评估结果, 具体地说, 步骤 203和步 骤 204可以替换为:
CBUS 服务器向信息源 (具体为业务引擎)发送携带有第一评估条件和 参照对象的搜索请求消息; 业务引擎查询参照对象的相关信息, 并根据参照 对象的相关信息和第一评估条件, 搜索满足第一评估条件的第一评估对象; CBUS服务器接收业务引擎返回的满足第一评估条件的第一评估对象; CBUS 服务器从其他业务引擎获取第一评估对象的相关信息, 例如呈现信息; CBUS 服务器将第一评估对象的相关信息与第二评估条件中所指定的固定值进行比 较, 得到满足第二评估条件的第二评估对象, 将第二评估对象作为评估结果。
在第三种情况下, CBUS 服务器也可以首先从其他业务引擎获取评估对 象的相关信息, 筛选出满足评估对象自身条件的评估对象, 然后进一步搜索 满足相对条件的评估对象, 也就是说, 对于相对评估条件为相对条件和评估 对象自身条件的组合的情况, 本实施例对两种条件进行评估顺序不作限定。
第四种情况: 若相对评估条件为相对条件(第一评估条件)和评估对象 自身条件(第二评估条件) 的组合, 且参照对象的相关信息和评估对象的相 关信息在不同信息源获取, 则步骤 203和步骤 204可以替换为: CBUS 服务器从第一信息源获取参照对象的相关信息; CBUS服务器向 第二信息源发送携带有第一评估条件和参照对象的相关信息的搜索请求消 息; 第二信息源根据第一评估条件和参照对象的相关信息, 搜索满足第一评 估条件的第一评估对象, 并返回给 CBUS服务器; CBUS服务器从其他业务 引擎获取第一评估对象的相关信息, 例如呈现信息; CBUS 服务器将第一评 估对象的相关信息与第二评估条件中所指定的固定值进行比较, 得到满足第 二评估条件的第二评估对象, 将第二评估对象作为评估结果。
在第四种情况下, CBUS 服务器也可以首先从其他业务引擎获取评估对 象的相关信息, 筛选出满足评估对象自身条件的评估对象, 然后进一步搜索 满足相对条件的评估对象, 也就是说, 对于相对评估条件为相对条件和评估 对象自身条件的组合的情况, 本实施例对两种条件进行评估顺序不作限定。
本实施例中, 评估请求消息中指定了参照对象、 相对评估条件、 评估设 置, 将参照对象的相关信息作为评估的依据, 获取满足相对评估条件的评估 对象, 在相对评估条件为相对条件时, 则无需评估请求者指定评估对象的某 项状态满足某固定值, 实现了根据参照对象的状态来评估; 在相对评估条件 为相对条件和评估对象自身条件的组合时, 可依次筛选满足这两个条件的评 估对象, 使得相对条件评估更具灵活性。
下面以具体场景为例, 进一步介绍本发明实施例的技术方案。 施例中, 用户 A为 CBUS业务的签约用户, 用户 A到一个陌生的城市拜访完 客户后, 希望通过 CBUS业务从一些好友中找出离自己最近的好友聚一聚, 设用户 A的 SIP URI为 sip:a@example.com,待评估的好友的 SIP URI分别为 sip: fl@example.com, sip: f2@example.com, sip: G@example.com。 口图 3所 示, 本实施例具体包括如下步骤:
步骤 301、 用户 A通过其终端上的 CBUS客户端设置相对评估条件、 评 估对象以及评估设置, 其中相对评估条件为地理位置与用户 A最为接近, 评 估对象为用户 A的三位好友, 评估设置为一次评估, 即只需要 CBUS服务器 返回一个满足条件的好友的 URI; CBUS客户端根据用户 A的设置, 将包括 相对评估条件、评估设置以及评估对象的评估请求消息发送给 CBUS服务器, 其中相对评估条件中指明了参照对象(本实施例为用户 A, 即评估请求发起 者) ;
本实施例中评估请求消息采用 HTTP GET的实现方式, 如下所示:
GET cbusgroup@example.com HTTP/1.1
"第一行代码为请求行, 其中 GET表示请求使用的是 HTTP中的 GET方 法 , cbusgroup@example.com表示该请求是对这个标口、对应的对象进行评估 , 本实施例中这个标识为一个群组 URI, HTTP/1.1表示协议版本"

</policyInputTemplate>
</policyInputData> 本实施例采用重用 PEEM中的 PEM-1接口来实现 CBUS客户端和 CBUS 服务器之间的信息交互, 即通过扩展 PEM-1接口中定义的输入输出模板的参 数来实现。 具体地说, 采用接口定义中已有的 1?01 ¥入]>元素来携带相 对评估条件,其中 <focus>元素表示参照对象,即为用户 A的 SIP URI, <filter> 元素表示规则, 其为枚举类型,取值可以为最近( nearest )或最远( farthest ) , 本实施例中取值为 nearest; 另外, 在标准的输入模板的基石出上, 扩展了类型 为 string的参数 <eva—type>, 用于表示评估设置, 该元素为枚举类型, 其取值 可以为: 一次评估 ( once ) , 实时评估 ( realtime ) , 结束评估 ( until— cond— matched ) , 本实施例中取值为 once。
步骤 302、 CBUS服务器接收到评估请求消息,对评估请求消息进行解析, 根据评估请求消息中的 Request URI ( si : cbus-group@example . com ) , 获取评 估对象, 即该 SIP URI表示的群组中的成员 (fl、 和 β为该群组的成员 ) , 并且获得相对评估条件为与用户 Α距离最近, 评估设置为一次评估;
步骤 303、 CBUS服务器向位置服务器发送获取参照对象用户 A以及评 估对象 si : f 1 @example . com , sip: f2@example.com, sip: fi@example.com位置 信息的请求消息;
本实施例中, 该请求消息采用 HTTP POST的实现方式, 如下所示: POST

步骤 402、 CBUS服务器接收到评估请求消息, 向 CBUS客户端返回 200
OK响应消息;
步骤 403、 CBUS 服务器解析评估请求消息, 获得评估对象为 fl@example.com, sip: f2@example.com, sip: f3@example.com, 相对评估条 件为距离用户 B的住址 500m范围内, 评估设置为结束评估;
步骤 404、 CBUS 服务器向共享档案可扩展标记语言文档管理服务器

步骤 502、 CBUS服务器接收到评估请求消息, 向 CBUS客户端返回 200 OK响应消息;
步骤 503、 CBUS服务器解析评估请求消息, 获得相对评估条件、 评估设 置以及参照对象;
步骤 504、 本实施例相对评估条件包括第一评估条件(相对条件)和第二 评估条件(评估对象自身条件), 其中第一评估条件为地理位置距离广告移动 台 1000m范围内的音乐爱好者, 第二评估条件为 IM在线, CBUS服务器向信 息源(本实施例具体为位置服务器)发送携带有第一评估条件和参照对象的搜 索请求消息, 请求查找地理位置距离广告移动台 1000m范围内的音乐爱好者; 本实施例搜索请求消息可以采用 HTTP POST的实现方式, 如下所示: POST

为了满 吏索功能,本实施例对移动定位协议( Mobile Location Protocol, 以下简称: MLP )进行了扩展, 具体地说, 为 svc— init元素定义了一个新的 属性一搜索(search ) , 表示向位置服务器发送的请求消息是否为搜索请求消 息, 若该属性的取值为真(true ) , 则表示为该请求消息为搜索请求消息, 若 该属性的取值为假(false ) , 则表示为该请求消息为位置信息的请求消息。
步骤 505、 位置服务器进行条件搜索, 查询参照对象的相关信息, 根据 参照对象的相关信息和第一评估条件,搜索出满足第一评估条件的评估对象; 具体地说, 首先确定广告移动台的位置, 根据广告移动台的位置确定距 离其 1000m范围内的人,并根据位置服务器内部的用户信息数据库中的信息, 对距离广告移动台 1000m范围内的人进行进一步筛选, 选择这部分人中兴趣 爱好包括音乐的人。
进一步的, 位置服务器还提供了用户可以选择是否公开自身位置信息的 功能, 若用户选择公开, 则还可以进一步指定公开自身位置信息的目的, 例 如用于接收评估、接收广告等, 只有在用户选择公开自身位置信息的情况下, 位置服务器才能够将该用户列入搜索请求消息的查找对象中。 为了降低位置 服务器处理搜索请求消息的时间, 对于愿意公开自身位置信息的用户, 位置 服务器可以将他们的位置信息映射到具体的地图区域中, 这样在接收到搜索 请求消息后, 能够快速地确定在某个区域范围内有哪些人存在。 另外, 位置 服务器提供了一个存储用户信息的数据库, 用于存储用户的常用基本信息, 便于对满足位置相对评估条件的人进行进一步地筛选, 避免 CBUS服务器到 其他存储用户信息的数据库(如 shared profile xdms )获取相关的信息, 从而 避免了 CBUS服务器与业务引擎之间存在过多的流量交互, 但这些用户信息 只在位置服务器内部使用, 属于私有信息。 若该存储用户信息的数据库以 xdms实现,则每个用户的常用基本信息可以由一个 xml文档表示,如下所示:
<?xml version="1.0" encoding="UTF-8"?>"表示 xml声明,,
<loc-userinfo xmlns = "urn :oma :xml :loc:user,,>"表示以、下是 Location 业务用户的基本信息"

</svc_result>
在扭「行完步骤 506之后, CBUS服务器根据第二评估条件和评估设置, 向相关业务引擎获取满足第一评估条件的评估对象的相关信息, 进而得出评 估结果, 在本实施例中, 第二评估条件为 IM业务在线, 则获取评估结果可 以包括如下步骤:
步骤 507、 CBUS服务器向呈现服务器发送获取呈现信息的请求消息,具 体为获取步骤 505 中筛选出的人 IM业务是否在线的呈现信息; 该请求消息 可以采用 SIP SUBSCRIBE的实现方式;
步骤 508、 呈现服务器将呈现信息返回给 CBUS服务器; 该返回消息可 以采用 SIP NOTIFY的实现方式;
步骤 509、 CBUS服务器对接收到的呈现信息进行判断, 筛选出 IM在线 的人, 即满足第二评估条件的评估对象, 从而获取评估结果;
步骤 510、 CBUS服务器将评估结果发送至广告移动台, 该发送的消息可 以采用 SIP NOTIFY的实现方式, 如下所示:
NOTIFY si : advertiser@example . com SIP/2.0
"表示以 SIP NOTIFY方式将评估结果反馈给用户 A"
Via: SIP/2.0/TCP
cbus-server.example.com;branch=z9hG4bK4EPlfSFQKl"表示到目前为止请 求消息经过的路径"

<entry
<entry
<entry
Figure imgf000033_0001
<entry uri="sip:userl28@example.com" />"评估结果 45"
</list>
</resource-lists>
进一步的, 由于步骤 501 中评估请求消息中包括<¾^111 min>元素及 <result— max>元素, 即相对评估条件中设置有评估结果数量的上限(200 )和 下限(50 ) , 则 CBUS服务器在返回评估结果之前, 将对本次评估结果进行 统计, 若评估结果的数量小于 50, 则 CBUS服务器会按照广告移动台设置的 评估间隔(<eva— internal>元素 )进行实时评估, 直至评估结果的数量达到 50, 再通知给广告移动台; 若本次评估结果的数量大于 200, 则 CBUS服务器分 多次将评估结果通知给广告移动台, 每次返回的评估结果数量最多为 200。
步骤 511、广告移动台向 CBUS服务器返回与步骤 510对应的 200 OK响 应消息。
由于本实施例采用实时评估的方式, 因此, CBUS 服务器按照评估间隔 ( <eva_interval> )进行定时评估 , 直到达到评估持续时间 ( <eva_duration> ) 为止。
另外, 本实施例不仅限于上述步骤 504〜步骤 509的执行顺序, 也可以 先获取评估对象的呈现信息, 筛选出 IM在线的人, 然后进一步搜索满足相 对评估条件的评估对象。
本实施例中, 评估请求消息中指定了参照对象、 相对评估条件、 评估设 置, 从位置服务器获取广告移动台的位置信息, 搜索满足部分相对评估条件 的评估对象, 并根据从呈现服务器获得的呈现信息, 进一步陣选完全满足相 对评估条件的评估对象, 得出评估结果; 本实施例实现了根据参照对象的状 态来评估, 使得评估更具灵活性。 进一步的, 由于广告移动台的位置在动态 改变, CBUS 服务器可自动获取广告移动台变化的位置信息, 从而避免了手 动改变相对评估条件而带来的不便。 施例中, CBUS业务支持以群组为单位的评估功能。 用户 A希望通过 CBUS 业务对其创建的三个群组进行评估, 寻找这三个群组中满足相对评估条件人 数最多的群组, 这三个群组的 SIP URI 分别为 sip:groupl@example.com, si : group2@example . com , sip:group2@example.com, 相对评估条件为地理位 置距离用户 A 500m范围以内, 活动状态为购物。 如图 6所示, 本实施例具 体包括如下步骤:
步骤 601、 用户 A通过其终端上的 CBUS客户端向 CBUS服务器发送评 估请求消息, 该评估请求消息中包括相对评估条件、 评估设置和评估对象, 相对评估条件为地理位置距离用户 A 500m范围以内、 活动状态为购物, 评 估对象为三个群组, 评估设置为一次评估, 其中相对评估条件中指明了参照 对象为用户 A;
该评估请求消息的消息体如下所示:

步骤 602、 CBUS服务器接收到评估请求消息, 向 CBUS客户端返回 200 OK响应消息;
步骤 603、 CBUS服务器解析评估请求消息, 获得相对评估条件、 评估设 置、 评估对象以及参照对象;
本步骤中还包括 CBUS服务器根据三个群组的群组标识, 从相关信息源 (如共享群组 xdms )获取群组成员的列表信息。
步骤 604、 CBUS服务器向呈现服务器发送获取群组成员活动状态信息的 请求消息, 请求获取三个群组中所有成员的活动状态信息; 该请求消息可以 采用 SIP SUBSCRIBE的实现方式;
步骤 605、 呈现服务器将群组成员活动状态信息返回给 CBUS服务器; 该返回消息可以采用 SIP NOTIFY的实现方式;
步骤 606、 CBUS服务器筛选出活动状态信息为购物的群组成员; 步骤 607、 CBUS服务器向位置服务器发送获取评估对象和参照对象位置 信息的请求消息, 请求获取用户 A以及步骤 506中筛选出的群组成员的位置 信息; 该请求消息可以采用 HTTP POST的实现方式;
步骤 608、 位置服务器向 CBUS服务器返回位置信息;
步骤 609、 CBUS服务器根据接收到的位置信息, 计算出用户 A与步骤
506中筛选出的群组成员的距离, 获取距离用户 A 500m范围内的群组成员, 并分别统计三个群组中满足条件的人数, 得出满足条件人数最多的群组为 sip:group2@example.com;
步骤 610、 CBUS服务器向 CBUS客户端返回评估结果; 该返回消息可 以采用 SIP NOTIFY的实现方式;
