IMS是 3GPP R5阶段增加的宽带码分多址接入系统(WCDMA ) 网络中 叠加在已有分组域之上的一个子系统, 采用分组域为其上层控制信令和媒体 传输的承载通道, 引入会话初始化协议(SIP )作为业务控制协议, 利用 SIP 简单、 易扩展、 媒体组合方便的特点, 通过将业务控制与承载控制分离, 提 供丰富的多媒体业务; IMS 中主要的功能实体包括控制用户注册、 会话控制 等功能的呼叫会话控制实体(CSCF )、 提供业务逻辑控制功能的应用服务器 ( AS )、 集中管理用户签约数据的归属签约用户服务器(HSS )以及用于实现 与电路交换网互通的媒体网关控制实体 (MGCF ), 用户通过当前所在地代理 呼叫会话控制实体(P-CSCF )接入 IMS, 会话和业务触发控制及与 AS的业 务控制交互则由其注册地的归属域服务呼叫会话控制实体( S-CSCF ) 完成。
HSS是 IMS子系统中用户最重要的数据库, 保存着所有和签约相关的信 息, 用于支持各个网络实体对呼叫和会话的处理, 具体包括: 用户的标识、 编号以及寻址信息; 用户的安全信息; 用户的位置信息以及用户的描述信息 等。 一个归属网络可以有一个或者多个 HSS, 取决于签约用户的数量, 网络 设备的容量以及具体的组网情况。 HSS 提供营业厅接口, 用于用户数据的维 护(例如增加、 修改、 删除用户签约数据等)。 同时 HSS支持它和查询呼叫会 话控制实体(I-CSCF )、 S-CSCF之间的接口 (Cx ), 和 AS之间的接口 (Sh ) 的用户数据下载。
在 IMS出现以前, 归属位置寄存器(HLR )是保存用户 CS域和 PS域数 据的实体, HLR支持 C接口(HLR和 GMSC/MSC之间接口), D接口(HLR 和 VLR之间接口), Gr接口 (HLR和 SGSN之间接口), Gc接口 ( HLR和 GGSN之间接口)。一般认为 HSS是 HLR的超集,两者合设, HSS内嵌了 HLR 的功能, 当用户进行网络登记时, 把登记的消息传递到 HLR/HSS, 并根据其 下载用户的签约数据进行后续的业务操作, AS通过 Sh接口能够获取、 订阅 IMS的数据并能部分获取 CS和 PS域的数据, 但在实际网络布局时也不排除 HLR和 HSS分设的情况。
通常情况下一个用户可能同时拥有多个设备用于运行通信业务, 这些设 备可以分别是电路域设备, IMS域设备, PSTN终端, 它们还可以归属于不同 的运营商, 由不同运营商提供电信服务, 同时这些设备可能分别具备不同的 能力, 能力不同限制了设备的某些应用或者特定的媒体类型 (如视频, 图像) 的支持。 3GPP在 R7阶段引入一项新的称为个人网管理(PNM ) 的业务, 该 业务以用户为中心, 将同一用户的设备或可为该用户使用的设备集中管理, 使用户得以充分利用其不同能力的终端或终端外设得到更好的业务体验。
在 PNM项目第一阶段, 主要关注个人网 (PN ) 内部各用户设备(UE ) 的管理, 提供 PN内各 UE间重定向服务和私网服务两种类型的业务。 其中重 定向服务是指用户事先激活 PN内的一个或多个 UE, 若激活多个 UE则这些 UE分别具有不同的优先级, 后续所有发往 PN内的任一 UE的业务请求都会 终结到上述激活的 UE, 例如, 将所有发往 PN内的任一 UE的视频电话请求 都重定向终结到 PN内屏幕最大的那个 UE上。 在 UE可以使用重定向业务码 和私网业务之前, UE必须首先登记到 PN网络内, 成为 PN网络中的网元。
如图 1所示, 为现有技术中 PN内 UE的登记流程示意图, 该方法包括以 下步驟:
步骤 101:在 UE发起登记流程之前,必须首先在 HSS上签约 PNM业务, HSS上记录这部分允许主动登记到 PN的 IP多媒体私有标识( IMPI ),并将这 些数据拷贝到 PNM服务器, 数据拷贝后 PNM服务器为此 PN分配一个唯一 的 PN标识。
步骤 102: 终端 UE发送的登记请求首先到达网络应用功能实体(NAJF ), NAF会对 UE的身份使用通用引导架构 ( GBA )鉴权方式进行鉴权并获得此 UE的 ΙΜΡΙ, 检查该 ΙΜΡΙ是否在 HSS中签约了 ΡΝΜ业务。
步骤 103: 鉴权通过后 NAF在请求中加入 ΙΜΡΙ并将请求转发至 ΡΝΜ服 务器。 若用户同时登记多个和此 UE关联的 IP多媒体公有标识( IMPU ), 则 需要在上述请求中增加指示, 指定其中一个为 PreferlMPU, PNM服务器收到 请求后根据请求中的 IMPI索 1找到对应的 PN记录, 并使用 IMPI向 HSS查 询和此 IMPI关联的 IMPU。
步骤 104: HSS返回 PNM服务器请求的数据,当登记请求中包含的 IMPU 都在 HSS返回的数据中时,则这些 IMPU有效,并且需要请求中的 PreferlMPU 为已注册状态, 这些条件都成立时, 则允许 PNM服务器将这些 IMPU和对应 的 IMPI数据增加到 PN中,即登记成功。在本申请文本中,所述已注册的 IMPU 为在 PLMN网絡中保存了信息的 IMPU。
所述的登记请求中还需要 UE包含国际移动设备标识(IMEI ), PNM服 务器保存此 IMEI并在返回登记成功的响应时也包含此 IMEI, 作为此 UE在 PN网络中的个人网元(PNE )标识, 后续所有此 UE发起的 PNM配置管理 请求, 都要包含 IMEI, 防止用户使用同一个通用集成电路卡(UICC )但替换 终端的情况发生。
在此现有技术的方法中, 当 UE登记到 PN时, 如果登记请求中携带多个 IMPU, 则指定其中一个为 PreferlMPU, 后续如果此 UE被激活并在重定向业务 中作为最终终结业务的 UE时, 此 PreferlMPU将会作为新的目标地址填充到业 务请求(Request-URI ) 头域。 但由于在 IMS中 S-CSCF会检查请求中包含的媒 体类型, 若此 PreferlMPU的签约数据中没有签约此媒体类型则 S-CSCF会拒绝 此请求, 导致呼叫受损, 会话接通率^ ί氐, 降低了用户业务感受。 发明内容

为了解决现有技术中由于登记请求中 UE携带多个 IMPU, 则指定其中一 个为 PreferlMPU, 激活时针对 UE激活并没有检查各 IMPU的签约情况,在后 续执行重定向业务过程中返回指定的 PreferlMPU时造成的若该 PreferlMPU的 签约数据中没有签约需要的媒体类型时 S-CSCF会拒绝此请求的后果,本发明 实施例中提出了新的 P M业务中 UE的登记和激活方法, 下面结合说明书附 图详细说明。
如图 2所示, 为本发明实施例登记系统的结构示意图, 该登记系统包含 已签约 FN]^ [业务的 UE11和 FNM服务器 12, 其中, UE11用于向所述 P M 服务器 12发起登记请求, 所述登记请求中含有一个或一个以上 IMPU; PNM 服务器 12用于接收所述 UE11发起的登记请求,并将已在 PLMN中注册 IMPU 的保存。
PNM服务器 12还用于向发起登记请求的 UE11返回登记请求响应,或向 发起登记请求的 UE11和该 IMPU对应的 UE返回登记请求响应。
PNM服务器 12用于在所述登记请求中登记类型为主动登记时, 向发起 登记请求的用户设备返回登记请求响应,此发起登记请求的 UE为该 IMPU关 联的; 当所述登记类型为邀请第三方登记时, 向发起登记请求的用户设备和 被邀请的用户设备返回登记请求响应, 此被邀请的 UE为该 IMPU关联的。
PNM服务器 12进一步用于当所述登记请求中的登记类型为主动登记时, 还保存发起登记请求的 UE11的标识; 当登记类型为邀请第三方登记时,还保 存被邀请的 UE的标识。
所述系统还包括所述 IMPU对应的用户设备的 HSS ,则所述 PNM服务器 12还用于向所述 HSS发送查询请求,该查询请求中包含与所述 IMPU关联的 IMPI, 并接收该 HSS返回的含有已注册的 IMPU的查询响应; 所述 HSS用于 根据接收到的所述 IMPI查询出所有与该 IMPI关联的已注册的 IMPU, 并将 舍有已注册的 IMPU的查询响应返回给所述 PNM服务器。
所述系统还包括 S-CSCF, 用于向所述 PNM服务器发送包含自身保存的 已注册的 IMPU的第三方注册请求, 并当接收到所述订阅所述 IMPU的注册 事件请求后,向所述 PNM服务器发送通知消息,该通知消息中包含所述 IMPU 关联于相同的私有用户标识的已注册的 IMPU; 所述 PNM服务器 12用于接 收到所述第三方注册请求后,向所述 S-CSCF发起订阅所述 IMPU的注册事件 请求, 并接收所述 S-CSCF返回的所述通知消息, 将登记请求中包含的 IMPU 与所述通知消息中的已注册的 IMPU比较, 获得登记请求中包含的 IMPU的 注册状态。
本发明实施例中系统的工作方式包括: 已签约 PNM业务 UE11 首先向 PNM服务器发起登记请求, 该登记请求中包含一个或一个以上的希望登记到 PN网中的 IMPU, 进一步地, 该登记请求中还可以包括登记类型和发起登记 请求的 UE的标识。 PNM服务器接收到该登记请求后,向被登记的 UE的 HSS 查询已在 PLMN中注册的 IMPU信息。 当登记类型为主动登记时, 所述被登 记的 UE即为发起登记请求的 UE, 当登记类型为邀请第三方登记时, 所述被 登记的 UE为被邀请的 UE。PNM服务器查询到已注册的 IMPU信息后与该登 记请求中的 IMPU进行比较, 将登记请求中包含的且已注册的 IMPU保存, 当登记类型为主动登记时, 还同时保存发起登记请求的 UE标识, 并向该 UE 返回登记请求响应; 当登记类型为邀请第三方登记时, 同时保存该被邀请的 ΌΕ, 并向该发起登记请求的 UE和该被邀请的 UE返回登记请求。
如图 3 所示, 为本发明实施例中登记方法的步骤流程示意图, 该登记的 方法主要步骤包括:
步骤 301: UE向 PNM服务器发起加入到 PN的登记请求,该请求中包含 了一个或多个需要登记到 PN的 IMPU、 与所述 IMPU关联的 IMPI和登记类 型, 该登记类型可以包括主动登记和邀请第三方登记。
若登记类型为邀请第三方登记时, PNM服务器通过 Sh接口查询当前为 被邀请的 UE服务的 S-CSCF, 将登记邀请请求发送至此 S-CSCF, 由 S-CSCF 进一步路由至被邀请的 UE, 被邀请的 UE收到此请求后若同意加入 PN, 贝' J 发起主动登记流程。
步骤 302: FNM服务器检查请求中包含的需要登记到 PN的所有 IMPU 的注册状态,对于在 PLMN中处于注册状态的 IMPU, PNM服务器在 PN中记 录这些 IMPU信息,认为登记成功,若请求消息中不存在满足上述条件的 IMPU, 则认为本次登记操作失败。
实施例 1为签约了 PNM业务的 UE ( PNM UE )主动登记的过程, 在本 实施例中该 PNM UE为 IMS终端, 如图 4所示, 该过程主要包括以下步骤: 步骤 401: PNM UE发起登记请求。
在 PNM UE发起登记请求之前, 就已经签约了 PNM业务, PNM服务器 保存签约了 PNM业务的 IMPU和' IMPI列表,并为这些属于同一 PN的 IMPU 和 IMPI分配一个唯一的标识 PN-ID。
此时 PNM UE发起登记请求, 该登记请求中包含了要登记到 PN网络的 IMPU和登记类型, 在本实施例中登记类型为主动登记, 进一步的,该登记请 求中还可以包括发起登记请求的 UE的设备标识。
步骤 402: NAF对该 PNM UE进行鉴权。
该 PNM UE发起的登记请求首先到达 NAF, NAF对其釆用 GBA鉴权方 式进行鉴权。 当鉴权通过后, NAF将此登记请求发送给 PNM服务器, 该请 求中不仅包含步骤 401中所述的信息, NAF还在此请求中增加了该已通过鉴 权的 UE的 IMPI。
步骤 403: PNM服务器向被登记 UE的 HSS查询已注册的 IMPU。
当 PNM服务器收到该请求后, 向该 HSS发送查询请求, 该查询请求中 包含与所述 IMPU 关联的 IMPI, 查询出和此 IMPI 关联的所有已经注册到 PLMN的 IMPU。
步骤 404: HSS向 PNM服务器返回查询响应。
HSS根据 PNM服务器发送的查询请求查询出所有已经注册的 IMPU, 并 将该信息发送给 PNM服务器。 步骤 405: PNM服务器对登记请求中包含的要登记到 PN网络的 IMPU 的注册状态进行检查。
PNM服务器将登记请求中包含的 IMPU和 HSS返回的已经注册的 IMPU 列表进行比较, 若登记请求中携带的 IMPU存在一个或多个包含在 HSS返回 的列表中时, PNM服务器才会允许这些包含在返回列表中的 IMPU登记到 PN 中, 其余未注册的 IMPU将不会被登记。 若登记请求中的 IMPU全部未注册, 则返回登记失败。
通过步骤 403至 405, 实现了确定 IMPU的注册状态的过程,在本发明实 施例中也可以利用其他的方法实现该确定过程, 例如: 在 IMPU的注册过程 中, 已注册成功的 IMPU保存在 S-CSCF中, 因此,该 S-CSCF根据签约 PNM 业务时为其制定的初始过滤规则 iFC向 PNM服务器发送第三方注册请求,该 请求中包括已注册的 IMPU。但是该 IMPU不一定是该 S-CSCF保存的所有已 注册的 IMPU, 因此, 当 PNM服务器接收到所述第三方注册请求后, 再向所 述 S-CSCF发起订阅所述 IMPU的注册事件( reg-event )请求, 该 S-CSCF接 收到该订阅请求后, 向所述 PNM服务器发送通知消息(Notify ), 该 Notify 中包含与所述 IMPU关联于相同的私有用户标识的已注册的 IMPU, 则 P M 服务器将登记请求中包含的 IMPU与所述 S-CSCF发送的已注册的 IMPU比 较, 获得登记请求中包含的 IMPU的注册状态。
另夕卜,该 S-CSCF接收到该订阅请求后,若保存的所述关联于相同的私有 用户标识的已注册的 IMPU 的注册状态改变时, 向所述 PNM服务器发送 Notify, 该 Notify 中包含注册状态改变后已注册的 IMPU, 即 S-CSCF通过 Notify实时向 PNM服务器发送已注册的 IMPU信息。
步骤 406: 设置 IMPU加入到 PN中的标识。
对于步驟 405 中注册状态检查完成的 IMPU, PNM服务器向所述 IMPU 对应的 HSS发送要求 HSS对所述 IMPU记录设置已经登记到所述 PN的标识 的请求, HSS收到该请求后根据所述 PN_ID判断所述 IMPU是否已经加入到 其它 PN中, 判断方法为: 查询 HSS中保存的所述 IMPU记录中是否已经存 在不同的 PN—ID,若没有,说明所述 IMPU没有加入其它 PN,则对所述 IMPU 记录设置标识成功, 指示这些 IMPU和 IMPI巳经加入到所述 PN中 , 若有, 说明 IMPU已经力 p入其它 PN,则对所述 IMPU记录设置标识失败,并向 PN 服务器返回设置响应。
在本实施例中,可以设定所述设置已经登记到所述 PN的标识的请求可以 为 Sh接口中的更新数据消息 (Sh-Update )。 且该请求还可以包含所述 PN对 应的号码标识( PN—ID )、 所述 IMPU和该 IMPU对应的 IMPI。
步骤 407: PNM服务器收到 HSS发送的设置成功响应后, 在 PN中存储 所述的 IMPU的信息, 这些信息可以包括: IMPU和 IMPI, 进一步的还可能保 存此登记到 PN的 UE的设备标识,随后 PNM 良务器向 UE返回登记请求响应。 当登记请求中包含的 IMPU全部未登记时, 该登记请求响应包含登记失败信 息; 当登记请求中包含的 IMPU部分或全部登记时, 该登记请求响应包含登 记成功信息和已保存的 IMPU列表。
实施例 2为 PNM UE1邀请 F M UE2加入 PN的第三方登记流程 , 在本实施 例中 PNM UE1和 PNM UE2都为 IMS终端,如图 5所示,该过程主要包括以下步 骤:
步骤 501: PNM UE1代 PNM UE2发起第三方登记请求。
PNM UE1通过 Ut接口发起第三方登记请求, 该请求中包含了被邀请的 UE2的 IMPU以及登记类型, 该登记类型为邀请第三方登记。 - 步骤 502: NAF对 UE1进行鉴权。
第三方登记请求被 UE1的超文本传输协议客户端( Http Client )首先发送 到 NAF。 NAF对 UE1的身份进行 GBA方式的鉴权, 当鉴权通过后 NAF将 该请求转发至 Pmi服务器, 该请求中除包含了步骤 501所述的信息外, 还包 含了 UE1的 IMPI。
步骤 503: PNM服务器对 UE1的权限进行检查。
只有具有邀请第主方的权限且已经登记到 PN的 UE才可以邀请其他 UE, 因此 PNM服务器要根据 UE1的 IMPI对 UE1的权限进行检查, 当检查通过 后 , PNM服务器通过 Sh接口向 UE2的 HSS2查询当前为 UE2服务的 S-CSCF, HSS2向 PNM服务器返回 UE2的 S-CSCF服务器名称, 若 S-CSCF不存在时 则返回错误信息。
步驟 504: PNM服务器向 UE2发送邀请 UE2登记的请求。
PNM服务器向该 S-CSCF发起邀请 UE2登记请求,该请求可以是 SIP中 的 MESSAGE消息, 若步驟 503中 HSS2返回的是错误信息, 则 PNM服务器 向 UE1返回错误; 该邀请请求由 S-CSCF路由到 P-CSCF, 再由 P-CSCF路由 到 UE2; UE2收到该请求后按照和该邀清请求相反的路径返回请求成功接收 的消息, 该消息到达 PNIVO 务器后, PNM服务器同时启动定时器。
步骤 505: 当 UE2同意加入 PN, 则向 PNM服务器发送登记请求。
若 UE2同意加入 PN, 则向 PNM服务器发送登记请求, 该请求中包含了 UE2的 IMPI和 IMPU, 进一步的,还可能包括 UE2的设备标识收到该请求后 PNM服务器停止步骤 504中启动的定时器; 若定时器超时 PNM服务器仍然. 没有收到 UE2的登记请求, 则 PNM服务器发送错误响应给 UE1。
步骤 506: UE2加入 PN。 该步骤与实施例 1中步骤 403至 407的主动登 记过程相同。
步骤 507: PNM服务器向 UE1和 UE2返回登记操作执行结果。
PNM服务器向 UE2返回登记请求响应,将登记成功的 IMPU列表返回给
UE2, 随即 PNM服务器再向 UE1返回登记操作执行结杲。

登记服务器单元 34还包括数据存储单元 37,当所述登记类型为主动登记 时,用于保存已注册的 IMPU以及发起登记请求的 UE标识; 当登记类型为邀 请第三方登记时, 保存已注册的 IMPU以及该被邀请的用户设备。
该实施例中 PNM服务器的工作方式包括: PNM服务器接收到已签约 PNM业务的 UE发起的登记请求后首先判断登记类型, 若为主动登记, 则判 断登记请求中包含的 IMPU的注册情况,将登记请求中包含的已注册的 IMPU 及发起登记请求的 UE标识保存, 并向该发起登记请求的 UE返回登记响应; 若为邀请第三方登记, 则先判断发起邀请请求的 UE的权限是否满足要求,且 该 UE是否已经登记到 PN, 若满足要求, 则向被邀请的 UE发起邀请登记请 求, 后续按照主动登记步骤进行, 但保存的信息除登记请求中包含的已注册 的 IMPU以外还包括被邀请的 UE标识,并同时向发起邀请的 UE和被邀请的 UE返回登记响应。 当实施例 1、 2中的 UE和 IMPU成功登记到 PN后, 后续该 UE就可以 发起激活请求。 下面结合说明书附图详细说明在登记成功后的本发明实施例 的激活过程。
如图 8所示, 为本发明实施例中激活系统结构示意图, 该激活系统包括 UE41和 PNM服务器 42。其中, UE41用于向 PNM服务器 42发送激活请求, 所述激活请求中包含激活配置, 所述激活配置包括 IMPU和激活层次的参数; PNM服务器 42用于保存已在 PN中登记的 UE和 IMPU信息, 并接收 UE41 发起的激活请求, 并分別对用户设备的能力和 IMPU的签约业务进行鉴权, 当鉴权通过且所述用户设备和 IMPU在 PN内已登记时, 保存所述激活配置。
PNM服务器 42用于接收到已签约 PNM业务的用户设备发起的登记请 求, 所述登记请求中含有一个或一个以上要登记到 PN 的 IMPU, 确定所述 IMPU在 PLMN中的注册状态, 再将已注册的 IMPU保存; 并且, 用于当所 述登记请求中包含登记类型为主动登记时, 保存发起登记请求的用户设备标 识; 当该登记类型为邀请第三方登记时, 保存被邀请的用户设备标识。
PNM服务器 42还用于向发起激活请求的 UE41返回激活响应,或向发起 激活请求的 UE和所述被激活的 UE返回激活响应。
PNM服务器 42用于当所述激活请求中包含的激活类型为主动激活时, 向发起激活请求的 UE返回激活响应; 当激活类型为邀请笫三方激活时, 向发 起激活请求的 UE和被激活的 UE返回激活响应。
PNM服务器 42用于当所述激活请求中的激活类型为主动激活时, 还保 存发起激活请求的用户设备标识, 所述发起激活请求的用户设备为已登记的, 且与所述 IMPU关联; 当所述激活类型为邀请第三方激活时, 还保存被邀请 的用户设备标识, 所述被邀请的用户设备为已登记的, 且与所述 IMPU关联。

如图 9 所示, 为本发明实施例中激活过程流程示意图, 在本实施例中设 定激活层次的参数取值为业务激活和业务成份激活中的一个或多个, 则该激 活方法主要包括以下步骤:
步骤 901: PNM UE向 PNM服务器发送激活请求。
在 UE被激活前,该被激活的 UE和与之关联的 IMPU必须是已经成功登 记到 PN的, 该登记方法可以是前述的登记方法, 也可以是其它的登记方法。 在登记成功后, UE发起激活请求, 该请求中包含激活配置, 所述激活配置包 括一个或多个要激活的 IMPU, 需要被重定向到这些 IMPU的业务码和 /或媒 体类型标识以及被激活的 UE的优先级参数,以及还可以包括被激活的 UE的 设备标识。 步骤 902: 获取被激活的 IMPU在 HSS中的注册状态。
PNM服务器向 HSS中发送获得此被激活的 IMPU注册状态的请求,当该 IMPU在 PLMN中的注册状态发生变化时, HSS将通知 PNM服务器, 只有处 于注册状态的 IMPU才能工作。 因此, 为了便于在注册状态发生改变时通知 PNM服务器,在激活成功后, PNM服务器将通过 Sh接口在 HSS对应的 IMPU 数据记录中增加自己的地址。
步骤 903: 当满足 UE能力和 IMPU签约信息要求时, PNM服务器将请 求中 IMPU激活。
PNM服务器对请求中 IMPU所签约的业务信息和该被激活的 UE的能力 信息进行鉴权,判断 IMPU的签约和 UE的能力是否支持被重定向的业务码和 媒体类型中的一个或多个。 当满足要求时, PNM服务器将请求中的激活配置 保存; 当不满足要求时, 则返回错误响应, 表示本次激活操作由于 IMPU签 约或 UE能力不支持被拒绝。
在本发明实施例中, 由于激活层次的参数取值为业务激活或业务成份激 活, 因此, 激活请求中包含了被重定向的业务码和被重定向的媒体类型的组 合, 由于业务中包含了一个或多个媒体类型, 所以当包含被重定向的业务时, 被激活的 IMPU的签约信息必须同时满足该业务包含的所有媒体类型。
当 UE和与之关联的 IMPU被激活后, PNM服务器收到呼叫始发端发起 的业务请求, 就可以执行重定向业务。 PNM服务器首先判断当前的业务请求 中包含的媒体类型,判断是否存在已激活的针对该媒体类型的 UE。当存在时, 则先执行针对媒体成份的重定向,当 PN中不存在针对媒体类型的激活设置时 再判断业务类型, 执行针对该业务类型的重定向。 若 PNM服务器判断针对业 务请求中的业务码和媒体类型中的一个或多个激活的 UE 同时存在多个对应 激活的 IMPU时, PNM服务器从中任选一个 IMPU返回或返回用户事先指定 的 IMPU。
在步骤 903之后, 当激活类型为主动激活时, PNM服务器向发起激活请 求的用户设备返回激活响应, 当激活类型为邀请第三方激活时, PNM服务器 向发起激活请求的用户设备和被激活的用户设备返回激活响应。
当激活类型为邀请第三方激活时, 在步骤 901后还包括步據:
A. PNM服务器判断该发起含有邀请第三方激活类型的激活请求的用户 设备是否具有邀请权限且已登记到 PN, 若是, 则向该被邀请的用户设备发送 邀请激活请求, 若不是, 则向该发起激活请求的用户设备返回激活失败响应。 当所述用户设备具有邀请权限且已登记到 PN时 ,该被邀请的用户设备接收到 该邀请激活请求后, 再向 PNM服务器发起激活请求,其中可能携带该被邀请 的用户设备标识。
因此, 在步驟 903中, 当激活类型为主动激活时, PNM服务器还可能将 发起激活请求的用户设备标识保存, 在保存时还要判断该发起激活请求的用 户设备是否为所述被激活的 IMPU关联的用户设备,且已经在 PN中登记,若 满足, 则继续执行下一步激活操作, 否则认为激活失败; 当激活类型为邀请第 三方激活时, PNM服务器将所述被邀请的用户设备标识保存, 在保存时同样 要判断该被邀请的用户设备是否为所述被激活的 IMPU关联的用户设备, 且 已经在 PN中登记,若满足,则继续执行下一步激活操作, 否则认为激活失败。
实施例 3为 UE主动发起激活的流程,在本实施例中,也设定激活层次的 参数取值为业务激活或业务成份激活, 如图 10所示, 该过程主要包括以下步 骤:
步骤 1001: PNM UE向 NAF发起激活请求。
当该 PNM UE和与之关联的 IMPU已经成功登记到 PN中, 则 PNM UE 通过 Ut接口向 NAF发送激活请求, 该请求包含了激活配置, 该激活配置包 括一个或多个需要激活的 IMPU, 以及要重定向到此 IMPU的业务的业务码和 /或媒体类型标识以及 UE 优先级参数, 还可以进一步包括发起激活请求的 PNM UE的设备标识。
步骤 1002: NAF对该 PNM UE的身份进行鉴权, 当鉴权通过后在该请求 中再加入 PNM UE的 IMPI, 将请求转发至 PNM服务器。
步骤 1003: 对 IMPU签约的业务信息和被激活的 UE的能力信息进行鉴 权。
PNM服务器收到激活请求后,判断被激活的 IMPU已经加入到 PN网络, 则向 HSS发送查询所述 IMPU签约的业务信息查询请求,并保存 HSS返回的 信息, 在本实施例中, 该签约的业务信息可以为通信业务标识(SID ), 另夕卜, 所述业务码也可以是 SID, 签约的业务信息查询请求可以为 Sh接口的查询消 息( Sh-Pull ), 同时 PNM Server向保存 UE能力信息的实体获取被激活的 UE 的能力信息。
在本实施例中, 当所述激活层次的参数取值为全局激活时, 所述 PNM服 务器向 HSS发送查询所述 IMPU签约的业务信息查询请求, 若能够获得该 IMPU签约的业务信息, 则所述 IMPU的签约业务鉴权通过。
当所述激活层次的参数取值为业务激活或业务成份激活时 , PNM服务器 将 IMPU签约的业务信息和与激活请求中被重定向的业务码和媒体类型中的 一个或多个进行比较, UE的能力信息与业务码和媒体类型中的一个或多个的 要求的能力进行比较, 若签约的业务信息中包含所述业务码,且 UE的能力信 息能够达到业务码和媒体类型中的一个或多个的要求的能力,则认为此 IMPU 可以针对该业务码和媒体类型中的一个或多个激活, 鉴权通过。
对 UE能力进行鉴权的步骤包括:当所述激活层次的参数取值为全局激活 时, 所述用户设备的能力满足所述 IMPU签约的业务部分或全部的要求, 则 鉴权通过; 当所述激活层次的参数取值为业务激活或业务成份激活时, 所述 用户设备的能力和所述 IMPU的签约的业务满足所述激活配置中包含的业务 码和媒体类型中的一个或多个的要求, 则鉴权通过。
PNM服务器收到激活请求后,若请求中携带用户设 i标识, PNM服务器 将要判断该激活请求中的用户设备是否为所述被激活的 IMPU关联的用户设 备, 且已经在 PN中登记, 若满足, 则继续执行下一步激活操作, 否则认为激 活失败, 向发起激活请求的 UE返回失败响应。
步驟 1004: 获取被激活的 IMPU在 HSS中的注册状态。
PNM服务器向 HSS中发送获得此被激活的 IMPU注册状态和签约的业务 信息的请求, HSS接收该请求后保存 PNM服务器的地址, 若保存成功, 则在 该被激活的 IMPU在 PLMN通信网络中的注册状态和该 IMPU签约的业务信 息中的一个或多个发生变化时发送消息给 P M服务器通知此事件,若保存失 败, 则向 PNM服务器返回请求失败信息。 当后续此 IMPU的注册状态和签约 的业务信息中的一个或多个发生变化时, HSS将会通知 PNM服务器。
步骤 1005: 当上述 HSS保存 PNM服务器的地址成功后, PNM服务器将 请求中的激活配置保存, 然后 PNM服务器向 PNM UE返回激活响应, 该响 应中包含激活成功的业务的业务码和对应的 IMPU, 以及该 IMPU关联的 UE 的优先级。
当 UE和与之关联的 IMPU被激活后, PNM服务器收到呼叫始发端发起 的业务请求, 就可以执行重定向业务。 实施例 4为当呼叫始发端发起业务请 求时, PN内触发重定向业务的过程, 如图 11 所示, 该过程主要包括以下步 骤:
步驟 1101: 呼叫始发端发起了业务请求, IMS域 UE作为被叫, 被叫归 属域 I-CSCF接收到业务请求。
步骤 1102: 被叫归属域 I-CSCF向保存被叫 UE信息的 HSS发送请求, 要求查询当前正在为被叫 UE服务的 S-CSCF服务器, 随即 HSS向 I-CSCF返 回当前为被叫 UE服务的 S-CSCF服务器的地址。
步骤 1103: I-CSCF向当前正在为被叫 UE服务的 S-CSCF转发该业务请 求, 为被叫 UE服务的 S-CSCF检测到条件匹配的初始过滤规则(iFC ), 并根 据此 iFC将业务債求通过 S-CSCF触发到 PNM服务器。
步骤 1104: PNM服务器收到该业务请求后, 确定需要执行重定向业务。 首先 PNM服务器判断是否存在针对媒体类型的已激活的 UE的 IMPU, 若存 在则执行针对媒体成份的重定向, 即将针对该媒体类型的具有最高优先级的 UE的 IMPU作为新的 Request-URI返回给 S-CSCF服务器; 若不存在, 则判 断该业务请求的业务类型,并根据业务类型查询出 PN内已激活的针对该业务 的具有最高优先级的 UE的 IMPU, 将此 IMPU作为新的 Request-URI返回给 S-CSCF服务器。
当 PNM服务器判断发现针对请求中的业务码和媒体类型中的一个或多 个激活的 UE同时存在一个以上的激活的 IMPU时, 则 PNM服务器从中任选 一个 IMPU作为业务请求的新的目标地址返回。
步骤 1105: S-CSCF服务器收到该新的 Request-URI后, 向新的目标 UE 发起业务请求。
实施例 5为 PNM服务器在一次会话中对会话的视频和语音成分分别重定 向到两个设备的过程, 如图 12所示, 为主要的步银流程示意图, 该方法主要 包括以下步據:
步骤 1201: PNM服务器将会话中的语音和视频业务重定向至 UEc和 UEd。 在本发明实施例中, 用户设备利用业务码和媒体类型标识来激活 UE, 在 本实施例, 所述媒体类型标识取值范围可以为会话描述协议(SDP ) 中 m行 表示媒体类型的参数取值范围, 因此可以设定用户利用基于视频业务的业务 码以及 SDP中 m行表示媒体类型的参数分别激活 UEc和 UEd, 分别作为语 音和视频的重定向 ΌΕ。
当激活过程成功后,主叫用户 UEa首先发起对 PN网絡中的被叫用户 UEb 的呼叫, 发起视频业务请求, 该视频业务请求首先接续到 S-CSCFb。 该 S-CSCFb接收到该业务请求后,通过 iFC将该业务请求触发到 PNM服务器中。
PNM服务器接收到该业务请求后, 判断该业务类型为视频业务, 并查询 出该: PN内存在基于视频业务中语音和视频成分而分别激活的 UEc和 UEd, 因此该 PNM服务器终结此业务请求, 并基于 PN内语音和视频成份的激活设 置重新产生两条会话请求, 并分別向 UEc和 UEd发送新产生的含有语音和视 频成分编解码方式描述的会话请求。 在本实施例中, PNM服务器发送这两个 会话请求的步骤为: P M服务器首先将原会话请求终止, 并将重新产生含有 语音成分编解码方式描迷的会话请求发送至 S-CSCFb, 由该 S-CSCFb将所迷 会话请求通过 S-CSCFc转发至 t!Ec。 当然, PNM服务器将含有视频成分编解 码方式描述的会话请求发送给 UEd的步骤类似。 步驟 1202: P M服务器将 UEc和 UEd的媒体协商及资源预留操作结果 返回给 UEa。
当 PNM服务器将会话请求发送至 UEc和 UEd后, 就可以分别与 UEc和 UEd进行媒体协商, 具体操作如下: PNM服务器将语音编解码方式通过新产 生的会话请求中的 SDP协议携带发送给 S-CSCFb,并由 S-CSCFb将该请求通 过 S-CSCFc转发至 UEc。 UEc接收到该请求后,获取所述编解码方式,若 UEc 基于请求中的编解码方式选择了接受的编解码方式后, 则通过 S-CSCFc和 S-CSCFb向 PNM服务器返回响应消息。 PNM服务器与 UEd的媒体协商过程 类似。当 PNM服务器与 UEc和 UEd进行媒体协商后,将协商结果返回给 UEa, 该返回方式可以为 PNM服务器将两个协商结果结合在一条消息中返回,也可 以将两个协商分别返回。 UEa接收到协商结果后, 若同意该协商结果, 则返 回响应消息, 并将该响应消息路由至 PNM服务器。 P M服务器再将该响应 消息中的语音和视频成分的编解码方式协商结果拆分出来, 分别发送给 UEc 和 UEd。 UEc和 UEd分别接收到该协商结果后, 分别进行资源预留操作, 并 将响应消息分别路由到 PNM服务器, 该 PNM服务器将 UEc和 UEd的媒体 协商及资源预留操作结果响应返回给 UEa, 该返回方式可以为将操作结果合 并为一条消息返回, 也可以通过两条消息分别返回。
步骤 1203: 视频会话建立, 语音数据在 UEa和 UEc之间交互,视频成分 在 UEa和 UEd之间交互。
在通话过程中,ΡΝΜ服务器始终保留在会话的信令路径中,当接收到 UEa 发送的视频数据会话请求后, 终结原请求并根据语音成分和视频成分的激活 设置产生两条会话请求, 并分别转发至 UEc和 UEd; 当接收到 UEc和 UEd 返回的响应后, 将两个响应合并后返回给 UEa。 当视频会话建立成功后, 语 音数据在 UEa和 UEc之间交互, 视频成分在 UEa和 UEd之间交互。
如图 13所示, 本发明实施例还提供一种 UE51 , 所述 UE51 包括发起激 活请求单元 52, 用于向 PNM服务器发送激活请求, 所述激活请求中包含激 活配置, 所述激活配置包括 IMPU和激活层次的参数。 UE51还包括接收单元 53 , 用于接收 PNM服务器返回的激活响应。
该 UE51的工作方式包括: 已在 PN中登记的 UE首先向 PNM服务器发 起激活请求, 该激活请求中包含激活配置, 所述激活配置包括 IMPU和激活 层次的参数, 随后等待 PNM服务器进行激活过程, 直到该激活过程结束后, 接收 PNM服务器返回的激活响应。
如图 14所示, 本发明实施例还提供一种 PNM服务器 61 , 所述 PNM服 务器 61包括登记信息存储单元 62、接收单元 63和激活服务器单元 64。其中, 登记信息存储单元 62用于存储登记在 PN中的用户设备和 IMPU信息; 接收 单元 63用于接收 UE发起的激活请求, 所述激活请求中包含激活配置, 所述 激活配置包括被激活的用户设备的 IMPU和激活层次的参数; 激活服务器单 元 64用于分别对所述用户设备的能力和 IMPU的签约业务进行鉴权, 当鉴权 通过且所述用户设备和 IMPU在 PN内已登记时, 保存所述激活配置。
登记信息存储单元 62包括接收单元 65、 查询单元 66和登记服务器单元 67。 其中, 接收单元 65用于接收用户设备发起的登记请求, 所述登记请求中 含有一个或一个以上 IMPU; 查询单元 66用于查询所述 IMPU在 PLMN中的 册的 IMPU保存。
激活服务器单元 64包括激活响应单元 68, 用于向发起激活请求的 UE返 回激活响应, 或向发起激活请求的 UE和所述被激活的 UE返回激活响应。
激活服务器单元 64包括判断单元 69,用于判断该激活请求中包含的激活 类型。 所述激活类型包括主动激活和邀请第三方激活。 当判断单元 69判断出 激活类型为主动激活时, 激活响应单元 68向发起激活请求的 UE返回激活响 应, 当判断单元 69判断出激活类型为邀请第三方激活时, 激活响应单元 68 向发起激活请求的 UE和被激活的 UE返回激活响应。
激活服务器单元 64还包括数据存储单元 70,用于当所述激活类型为主动 激活时,还保存发起激活请求的 UE标识保存; 当所述激活类型为邀请第三方 激活时, 还保存被邀请的 UE标识保存。 该 PNM服务器的工作方式包括: 接收 UE发起的激活请求后判断判断激 活类型, 当激活类型为主动激活时, PNM服务器判断该发起激活请求的 UE 的能力和激活请求中的 IMPU签约信息是否满足所述业务码和媒体类型中的 一个或多个的要求, 且该 UE和 IMPU为 PNM服务器已登记的, 若满足这两 个条件, PNM服务器则保存所述激活配置和该 UE的标识, 并向该 UE返回 激活响应。 当激活类型为邀请第三方激活时, PNM服务器判断该发起邀请的 UE的权限和该 UE是否已经登记到 PN,若满足, 则向该被邀请的 UE发起邀 请激活请求, 此时被邀请的 UE重复主动激活过程, PNM服务器向该发起邀 请的 UE和被邀请的 UE返回激活响应。
实施例 6为 PNM服务器在一次会话中对会话的视频和语音成分分别重定 向到两个设备的过程, 如图 15所示, 为主要的步骤流程示意图, 该方法主要 包括以下步骤:
步驟 1501 : P M服务器将语音会话请求和视频会话请求分别重定向至 UEc和 UEd。
在本发明实施例中, 用户设备利用业务码和媒体类型标识来激活 UE, 在 本实施例, 所述媒体类型标识取值范围可以为会话描述协议(SDP ) 中 m行 表示媒体类型的参数取值范围, 因此可以设定用户利用基于视频业务的业务 码以及 SDP中 m行表示媒体类型的参数分别激活 UEc和 UEd, 分别作为语 音和视频的重定向 /激活 UE。
当激活过程成功后, 主叫方首先发起对 PN网络中的被叫用户 UEb的呼 叫, 发起视频业务请求(INVITE ), 该 INVITE中包含含有语音成分编解码方 式描述( audio )和含有视频成分编解码方式描述( video )。 该 INVITE首先接 续到 S-CSCFb, 该 S-CSCFb接收到该 INVITE后, 通过 iFC将该业务请求触 发到 PNM服务器中。
PNM服务器接收到该 INVITE后, 判断该业务类型为视频业务, 执行重 定向业务£辑,查询出该 PN内存在基于视频业务中语音和视频成分而分别激 活的 UEc和 UEd, 因此该 PNM服务器终结此业务请求, 并基于 PN内语音和 视频成份的激活设置重新产生两条会话请求, 并分别向 UEc和 UEd发送新产 生的含有语音和视频成分编解码方式描述的会话请求。 在本实施例中, PNM 服务器发送这两个会话请求的步骤为: PNM服务器首先将原会话请求终止, 并将重新产生含有语音成分编解码方式描述的会话请求 ( INVITE
( SDP.audio ) )发送至 S-CSCFb,由该 S-CSCFb将所述会话请求通过 S-CSCFc 转发至 UEc。 当然, PNM服务器将含有视频成分编解码方式描述的会话请求
( INVITE ( SDP.video ) )发送给 UEd的步骤类似。
当 UEc 和 UEd 分别接收到所述 INVITE ( SDP.audio ) 和 INVITE
( SDP.video )后, 将分别将语音成分响应消息(Offer Response ( audio ) )和 视频成分响应消息( Offer Response ( video ) )通过 S— CSCFb返回给 PNM AS。 其中, Offer Response ( audio )包含了 UEc所支持的语音成分, Offer Response
( video ) 包含了 UEd所支持的视频成分。
步骤 1502: PNM服务器将 UEc和 UEd的媒体协商及资源预留操作结果 返回给主叫方。
当 PNM服务器接收到 UEc和 UEd返回的 Offer ResponseC audio )和 Offer Response ( video )后, 将这两条响应消息综合成为一个新的媒体协商结果, 并将该结果返回给主叫方, 当然, 该结果可以是通过 183消息发送的。
主叫方接收到的媒体协商结果中, 包含的 UEc和 UEd能够支持的语音成 分和视频成分的编解码方式可能有多种, 因此, 主叫方将从接收到的媒体协 商结果中选择一种语音成分和视频成分编解码方式, 并将该选择的信息通过 响应消息(Response Conf )返回给 S— CSCFb, 由 S— CSCFb 将该响应消息 ( Response Conf)返回给 PMM AS。
PNM AS再将接收到的响应消息中的语音成分和视频成分编解码方式拆 分出来, 分别通过响应消息发送给 UEc和 UEd, 显然, 该发送过程是通过 S_CSCFb转发消息实现的。
UEc和 UEd分别接收到包含主叫方最终选定的语音成分和视频成分的编 解码方式响应消息后, 分别进行泉终媒体协商结果确定和资源预留操作, 并 将操作执行后的响应消息分别路由到, 该 PNM服务器将 UEc和 UEd的媒体 协商及资源预留操作结果响应消息返回给主叫方, 该返回方式可以为将操作 结果合并为一条消息返回, 也可以通过两条消息分别返回。
步课 1503: 视频会话建立, 语音数据在主叫方和 UEc之间交互, 视频成 分在主叫方和 UEd之间交互。
视频会话建立时, 主叫方收到 S—CSCFb转发的 UEc和 UEd的振铃指示 ( Ringing ), 该指示可以是通过 200消息发送的。
视频会话开始后, 主叫方通过传输协议, 如实时传输协议(RTP )将语音 和视频数据分别发送给 UEc和 UEd。
在会话的最终建立过程中, PNM服务器始终保留在会话的信令路径中, 负责将被叫侧的两方 UEc和 UEd的响应合并为一条消息返回给主叫方或者将 主叫方的消息拆分为两条消息分发给 UEc和 UEd, 会话建立成功后语音成份 在主叫终端和 UEc之间进行交互, 而视频成份在主叫终端和 UEd之间进行交 互。
综合上述实施例, 由于该 IMPU签约了业务请求中包含的媒体类型, 所 以只要重定向后的目标 UE可及, 该业务请求可以到达此 UE, 不存在因为该 IMPU没有签约业务请求中包含的媒体类型导致本次业务请求被网络拒绝的 问题。
显然, 本领域的技术人员可以对本发明进行各种改动和变型而不脱离本 发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内, 则本发明也意图包含这些改动和变型在内。
