Description

通知消息发送方法及控制单元、 发布单元和接收单元装置 本申请要求了 2008年 5月 16日提交的， 申请号为 200810111872.X, 发 明名称为 "通知消息发送方法及控制单元、 发布单元和接收单元装置" 的中 国申请的优先权， 其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信技术领域， 尤其涉及一种通知消息发送方法及控 制单元、 发布单元和接收单元装置。
背景技术
通知消息是一种由网络实体发送给用户终端显示的， 由文本、 图片、 音 频、 视频、 脚本语言等任意组合的消息， 如 IP多媒体子系统（IP Multimedia Subsystem; 以下简称： IMS ) 网络中的短消息、 多媒体短消息等， 因特网协 议电视 ( Internet Protocol Television; 以下简称： IPTV )业务中的通知消息， 其中网络实体包括 IMS实体（如 S-CSCF、 P-CSCF, SCF、 AS、 SB、 GGSN、 NASS等实体）、 IPTV业务实体（如 SCF、 SSF、 SDF等）， 同一消息可以在 同一时刻由网络发送给任意用户终端， 这些用户可能处于任何状态下， 如刚 附着、 刚进行 IMS注册、 或者正在享用其他业务（如 IPTV业务、 玩游戏） 等。
IMS是第三代（ the 3rd Generation, 3G )移动网实现分组话音和分组数据、 提供统一的多媒体业务和应用的目标网络。 在 IMS网络中存在各种类型的通 知消息， 如下场景： 某用户账户余额不足时， IMS 网络通知该用户账户余额 不足； 本域内发生重大紧急事件， IMS 网络实体向本域内所有用户通知该紧 急事件； IMS 网络本号段内的网络处理单元进行系统升级， IMS 网络向该号 段内所有的用户通知该情况等。
IPTV业务是一种利用宽带有线电视网， 集互联网、 多媒体、 通讯等多种 技术于一体， 向家庭用户提供包括数字电视在内的多种交互式服务的崭新技 术，所使用的通信核心网可以是 IMS网络或其他非 IMS网络（如 NGN )。 IPTV 系统不但能够提供基本的直播（BC )业务、 点播（ VOD )业务和录制（PVR ) 业务， 而且还能够提供各种增强业务， 包括按次观看付费 （Pay Per View; 以 下简称： PPV )业务、 推荐业务、 广告业务、 CallerlD业务、 呈现（Presence ) 业务、 预览业务、 书签业务、 交互式电视（intercative TV; 简称： iTV )业务、 用户发起的视频 （Consumer Originated Video; 以下简称： COV )业务、 家长 控制业务等。 在 IPTV 系统的基本业务和增强业务中存在各种类型的通知消 息， 如下场景： 在广告业务中， 广告作为音视频通知消息下发给观看同一节 目的所有用户； 个性化广告中还可以为观看同一节目的偏好信息相同的用户 下发同一个广告， 偏好信息不同的用户下发不同的广告； PPV 业务为向用户 提供的付费电视节目， 使用户能独立与业务包来签约业务， 分为提前预定
( OPPV - Order-ahead PPV )和即时预定（IPPV - Impulse PPV ), 当用户 提前预定了 PPV节目时， 到 PPV节目播放时间时， 网络生成提醒信息发送给 该用户， 提醒信息为通知消息的一种应用； PPV 业务即时预订中， 用户免费 观看到结束时间后， 网络生成通知消息发送给正在免费观看 PPV节目的用户 提醒是否付费； 推荐业务中， 网络实时向用户发送推荐信息， 推荐符合用户 偏好或最新上线的节目， 推荐信息为通知消息的一种应用； 紧急提醒业务
( Emergency Alert Service； 以下简称： EAS ) 业务中， 发生紧急事件时， 网 络向本域内的所有用户发送紧急提醒通知（ Emergency Alert Notification; 以下 简称： EAN )通知消息， 请求呈现该 EAN消息或者根据该 EAN消息的内容 强制换台等。
现有技术中， IMS网络使用会话初始化协议（ Session Initiation Protocol; 以下简称： SIP )信令消息携带通知消息， 由核心网解析并路由至通知对象。 例如， 使用 " SIP Message/info " 消息的消息体 ( Body ) 携带通知消息， "Request-URI" 携带通知对象身份标识， 由 IMS 核心网 （Core IMS )解析 "Request-URI"并将通知消息路由至通知对象。再如，使用 "SIP Message/info 消息的 Body 携带通知消息， 同时在 Body 中携带使用可扩展标记语言 ( extensible Markup Language; 简称： XML )格式描述的通知对象身份列表， 由网络实体 "MESSAGE URI-List Service"将其拆分为与每个通知对象对应的 消息， 发送到对应的用户终端。 IPTV系统中， 网络可以通过在节目媒体流中 封装通知消息， 发送给观看这个节目的所有用户， 例如在一个直播频道中， 网络发送一条通知消息， 所有的用户均可以收到。
发明人在实现本发明的过程中发现： IMS 网络中， 在发送通知消息前网 络需要首先感知用户身份标识， 而有些情况下网络是无法感知到用户的身份 标识的， 例如用户仅附着到这个网络， 尚未进行任何注册， 因此造成无法发 送通知消息； 当同时向多个用户发送通知消息时， 网络需要为每个用户发送 一条携带通知消息的信令消息，造成网络资源浪费， 负荷加重； IPTV系统中， 在直播频道中发送通知消息时， 每个观看该频道节目的用户都能收到通知消 息， 不能做到向组播组中的部分用户发送通知消息， 无法满足个性化需求。 发明内容
本发明实施例提供一种通知消息发送方法及控制单元、 发布单元和接收 单元装置， 用以解决现有技术中发送通知消息前需要感知用户身份标识、 网 络资源浪费， 无法实现个性化需求的缺陷， 实现网络负荷小， 且满足个性化 需求。

在发送给发布单元的通知消息中包括通知内容信息， 如广告内容、 通知 正文部分。 进一步地， 为了满足通知消息发送的个性化需求， 该通知消息中 还可以包含通知对象指示信息， 用于指示接收到通知消息的接收单元是否显 示该通知消息； 还可以包含通知消息相关节目指示信息， 用于终端实现节目 和通知消息的关联； 还可以包含通知消息产生单元指示信息， 用于指示通知 消息的来源地。 也就是说， 在一条通知消息中除了包括通知内容信息之外， 还可以包括通知对象指示信息、 通知消息相关节目指示信息和通知消息产生 单元指示信息中的任意一种或几种的组合。
所述通知对象为接收通知内容信息的所有用户， 通知对象为网络根据触 发条件指定的， 可以是明确身份的用户或不明确身份的用户， 如 PPV节目到 时提醒时， 通知对象为预定了 PPV节目的用户， 预定 PPV节目的用户信息在 网络均有存储， 通知对象为指定用户身份的用户； 再如向观看某个频道的用 户发送广告时， 通知对象为观看该频道的所有用户；
当通知对象为明确身份的用户且只有一个时， 携带的通知对象指示信息 为该通知对象的用户标识， 如 IMS公共用户标识；
当通知对象为明确身份的用户且有一个以上时， 携带的通知对象指示信 息为所有通知对象的用户标识， 多个用户标识可以罗列表示， 也可以通过正 则表达式的形式表示。
通知对象也可以是不明确身份的用户， 例如观看节目的所有用户、 观看 某个节目的满足某个条件的所有用户、 在某个区域内的用户等， 此种情况下， 通知消息中可以不携带通知对象指示信息， 或通知对象指示信息为 0或空或 全部； 通知对象指示信息还可以是条件表达式， 如偏好满足什么条件（如年 龄在 18-28之间） 的用户、 终端能力满足什么条件 (如终端为 SD ) 的用户、 正在观看什么节目 （如 CCTV1频道 )的用户、 在什么域内 （如 shenzhen.com 域） 的用户等。
所述通知消息相关节目可以是由网络指定， 如由网络指定的广告所属的 节目 （广告在 CCTV1频道播放）； 或通知对象正在观看的节目， 或通知内容 信息所依附的节目， 如设定 PPV节目到时提醒的用户正在观看的节目， 可以 通过获取该用户的 "IPTV Presence" 信息来获取用户当前正在观看的节目。 通知消息相关节目指示信息用于实现节目与通知内容的关联， 可以是通知消 息相关节目标识信息， 如网络指定在 CCTV1频道播放广告， 相关节目指示为 CCTV1频道标识， 终端在 CCTV1频道的播放区域内显示通知消息； 再如预 定 PPV节目的用户正在观看 VOD1节目， 相关节目指示为 VOD1节目标识， 终端在 VOD1节目播放区域内显示提醒信息等。
所述通知消息产生单元指示信息为产生通知内容信息的实体或网络的标 识信息， 如 "Shenzhen.com" 网络标识、 EAS-SCF实体标识等 通知消息中还可以包含多条通知内容信息， 以及与通知内容信息对应的 通知对象指示信息、 通知消息相关节目指示信息、 通知消息产生单元指示信 息， 这些通知内容对应的通知对象指示信息和通知相关节目指示信息可以相 同也可以不同。
控制单元可以根据通知消息或根据网络配置或控制单元自身存储信息决 定将该通知消息发送给哪个发布单元。 如发布单元为控制单元存储的附着到 其上的网络实体， 例如控制单元为 AS, 发布单元为第三方注册到 AS上的所 有用户注册的 S-CSCF ( Servlng-Call Session Control Function, 服务 -呼叫会话 控制功能）； 再如控制单元根据通知消息相关节目来决定发布单元， 控制单元 获取相关节目的元数据信息找到提供节目媒体流的 MF地址，例如 SCF从 SSF 获取 CCTV1频道的元数据信息， 找到 MF的地址； 或控制单元在自身存储的 信息中获取提供节目媒体流的 MF地址； 再如 SCF根据通知对象和相关节目 从自身存储的信息中查找出 MF的地址； 当相关节目为单播节目时， MF地址 为提供单播媒体流的媒体服务器地址， 当相关节目为多播节目时， MF地址为 提供多播媒体流的多播源地址。
控制单元在确定接收该通知消息的发布单元后， 将包括通知内容信息和 各种指示信息的通知消息发送给发布单元。 当发布单元为 MF 时， 通知消息 相关节目指示信息用于指示 MF将通知消息封装在哪个节目的媒体流中， 通 知对象指示信息用于指示 MF将通知消息封装在发送给哪个用户的媒体流中。 通知消息可以是标准的 HTTP 消息、 SIP 消息等， 也可以是私有的消息， 如 SOAP命令、 Mpeg4媒体内容等。控制单元发送给 MF的通知消息可以通过控 制单元与 MF之间的直接的 SIP接口、 HTTP接口、 RTP/RTCP、 UDP、 TCP、 RTSP接口或私有协议接口等， 或间接经过 IMS核心网的 SIP接口发送。如在 直接接口中通过 HTTP信令消息传送；再如在直接接口中通过控制单元与 MF 之间 SIP会话协商建立的媒体通道发送；再如在间接接口中通过 SIP信令消息 传送； 再如直接接口和间接接口联合使用， 通过间接 SIP接口协商直接接口 的媒体通道，再通过协商好的媒体通道发送通知消息。当发布单元可以为 IMS 核心网的网络实体（如 S-CSCF、 P-CSCF, SCF、 AS等）、 GGSN或 NASS等 实体时， 通知对象指示信息用于指示发布单元将通知消息转发给哪些用户， 通知消息为标准 SIP消息， 可以经过 SIP接口发送到发布单元。
步骤 101 ,发布单元接收控制单元发送的通知消息后， 确定接收所述通知 消息的接收单元， 并将所述通知消息发送给所述接收单元；
发布单元将该通知消息向附着在其上的接收单元设备进行广播（所有的、 或一群的）发送， 由于发布单元分为负责媒体层面的 MF和负责信令层面的 IMS 核心网实体两种， 以下分别对两种发布单元接收到通知消息后的处理过 程进行详细说明。
当发布单元为 MF且通知消息中包含一条通知内容时：
当通知消息不包含该通知消息对应的通知消息相关节目指示信息时， MF 默认通知消息相关节目为自身所能提供的所有节目；
当通知消息包含该通知消息对应的通知对象指示信息， 且通知消息相关 节目为单播时， MF将对应的通知消息单独打包或与通知对象正在观看的消息 相关节目的媒体流一起打包， 通过与通知对象之间建立的媒体通道发送给通 知对象即用户终端； 当通知消息相关节目为组播时， MF将通知消息单独打包 或与消息相关节目媒体流一起打包， 发送给各个多播复制点， 然后用户终端 从多播复制点获取媒体内容；
当通知消息不包含该通知消息对应的通知对象指示信息或通知对象指示 信息为 0或空或全部， 且当通知消息相关节目为单播时， MF将通知消息单独 打包或与观看通知消息相关节目的每个用户的媒体流一起打包， 通过与每个 观看通知消息相关节目的用户终端之间建立的媒体通道发送给用户终端； 当 通知消息相关节目为组播时， MF将通知消息单独打包或与通知消息相关节目 媒体流一起打包， 发送给各个多播复制点， 然后用户终端从多播复制点获取 媒体内容； 当该通知消息对应的通知对象指示信息为条件表达式， 且当通知消息相 关节目为单播时， MF可以将通知消息单独打包或与观看通知消息相关节目的 每个用户的媒体流一起打包， 通过与每个观看通知消息相关节目的用户终端 之间建立的媒体通道发送给用户终端； MF还可以将通知消息单独打包或与观 看通知消息相关节目的， 且满足条件表达式的用户的媒体流一起打包， 通过 与这些用户终端之间建立的媒体通道发送给用户终端； 当封装节目为组播时， MF将通知消息单独打包或与通知消息相关节目媒体流一起打包，发送给各个 多播复制点， 用户终端再从多播复制点获取媒体内容， 同时 MF 可以将根据 条件表达式确定的通知对象信息添加进通知消息中， 作为通知对象指示信息 一起发送给用户终端；
当通知消息不包含该通知消息对应的通知对象指示信息或通知对象指示 信息为 0或空或全部时， MF还可以根据通知消息产生单元指示信息确定通知 对象时， 当通知消息相关节目为单播时， MF可以将通知消息单独打包或与观 看通知消息相关节目的根据通知消息产生单元确定的通知对象即用户终端的 媒体流一起打包， 通过与这些用户终端之间建立的媒体通道发送给用户终端； 当封装节目为组播时， MF可以将根据通知消息产生单元确定的通知对象信息 添加进通知消息中作为通知对象指示信息， 将该通知消息单独打包或与通知 消息相关节目的媒体流一起打包 , 发送给各个多播复制点， 用户终端从多播 复制点获取媒体内容。
当通知消息中包含多条通知内容信息时， MF可以根据每条通知内容对应 的通知消息相关节目指示信息和通知对象指示信息进行上述处理； 同时当存 在通知内容对应的通知消息相关节目相同且为组播时， MF可以将这些通知消 息同时进行上述封装打包处理。
发布单元可以为 IMS核心网的网络实体（如 S-CSCF、 P-CSCF, SCF、 AS等）、 GGSN、 NASS等实体， 且当通知消息中包含一条通知内容信息时： 当通知消息包含该通知消息对应的通知对象指示信息时， 发布单元根据 通知对象指示信息确定接收通知消息的通知对象， 将通知消息发送到对应的 通知对象即接收单元；
当通知消息不包含该通知消息对应的通知对象指示信息或该通知消息对 应的通知对象指示信息为 0或空或全部时， 发布单元确定通知对象为附着在 所述发布单元上的所有接收单元， 可以将通知消息发送给附着到其上的所有 接收单元， 如 P-CSCF将通知消息发送给所有在 P-CSCF上登记的用户， 再如 GGSN将通知消息发送给所有在 GGSN上接入核心网 CN的用户； 发布单元 还可以根据通知消息产生单元指示信息来确定接收所述通知消息的通知对象 即接收单元， 将通知消息发送给确定的通知对象， 如为通知消息产生单元指 示信息为 "EAS-SCF@shenzhen.com" , S-CSCF判断为 EAS通知消息， 域信 息为 "shenzhen.com" , 于是查找附着在其上的位置信息在 "shenzhen" 的用 户的 P-CSCF, 将通知消息发送给这些 P-CSCF, P-CSCF在根据通知消息产生 单元指示信息查找附着在其上的位置信息在 "Shenzhen" 的用户， 将通知消息 发送给这些用户。 其中 S-CSCF可以在用户发起注册时， 保存用户标识、 用户 位置信息和 P-CSCF之间的对应关系， 再如 GGSN根据包含通知消息 IP包的 产生单元 P-CSCF,如 P-CSCF的 IP地址或端口等，将通知消息发送给所有在 GGSN上接入核心网 CN的用户；
当通知消息包含该通知消息对应的通知对象指示信息为条件表达式时， 发布单元可以向附着在其上的每个接收单元发送该通知消息， 还可以将通知 消息发送给附着在其上的满足条件表达式的接收单元， 如为条件表达式 "发 送给在 'shenzhen' 的用户"， S-CSCF查找附着在其上的并附着了位置信息在 "shenzhen" 的用户的 P-CSCF, 将通知消息发送给这些 P-CSCF, P-CSCF在 根据条件表达式查找附着在其上的位置信息在 "shenzhen" 的用户， 将通知消 息发送给这些用户。
当通知消息中包含多条通知内容信息时， 发布单元可以根据每条通知内 容对应的通知对象指示信息进行上述处理； 同时当通知内容信息对应的通知 对象相同时， MF可以将这些通知消息同时进行上述处理。
步骤 102, 接收单元解析收到的通知消息， 决定处理或抛弃该通知消息； 当通知消息中携带通知对象指示信息时， 接收单元即用户终端解析通知 对象指示信息， 判断通知对象中是否包含本身， 若包含， 则呈现该通知内容 信息或根据通知内容信息进行指定的操作， 否则抛弃该通知消息； 若通知消 息中包含通知消息相关节目指示信息， 则在通知消息相关节目媒体内容显示 的区域内呈现该通知内容， 否则在终端整个显示区域内呈现该通知消息； 当通知消息中不携带通知对象指示信息或通知对象指示信息为 0或空或 全部时， 收到通知消息的用户终端均呈现该通知内容信息或根据通知内容信 息进行指定的操作； 若包含通知消息相关节目指示信息， 则在通知消息相关 节目媒体内容显示的区域内呈现该通知内容， 否则在终端整个显示区域内呈 现该通知消息；
当通知消息中携带的通知对象指示信息为条件表达式时， 与终端判断自 己是否满足预置条件， 满足时呈现该通知内容信息或根据通知内容信息进行 指定的操作； 若包含通知消息相关节目指示信息， 则在通知消息相关节目媒 体内容显示的区域内呈现该通知内容， 否则在终端整个显示区域内呈现该通 知消息。
本发明实施例提供的通知消息发送方法应用在 IMS网络中时， 网络可以 在同一时刻将同一通知消息发送给处于任意状态下的单个用户； 网络在同一 时刻将同一通知消息发送给处于不同状态的一个以上（本域内所有或部分） 的用户， 如 IMS网络的紧急消息， 需要在同一时刻发送给附着在该网络的所 有用户； 同时存在网络能感知需要通知的用户的身份信息， 还存在网络不能 感知到需要通知的用户的身份情况； 方法应用在 IPTV 系统单 /组播节目发送 中， 网络在同一时刻将同一通知消息发送给观看该节目的所有用户； 单 /组播 节目中， 网络在同一时刻将一通知消息发送给观看该节目的部分用户 （如满 足特定条件的用户）， 进一步同一时刻将另一通知消息发送给观看该节目的其 他部分用户； 避免了不能获知用户身份的情况下无法发送通知消息的情况， 减少了通知消息的发送数量， 满足了通知消息发送的个性化需求， 并做到网 络负荷最小。
