Description

一种信息推送方法、 装置和系统 本申请要求于 2010年 7月 6日提交中国专利局, 申请号为 201010224328.3 , 发明名称为"一种信息推送方法、 装置和系统"的中国专利申请的优先权, 其全 部内容通过引用结合在本申请中。 技术领域
本发明实施例涉及无线通信领域,尤其涉及一种在无线网络上实现信息推 送的方法, 具体为一种无线网络信息推送方法、 装置和系统。
背景技术
Apple公司推出了 Push Notification (推送通知)方案, 应用于 iphone。 该 方案采取 Push (推送) 的方式, 当用户某一应用有事件到达时 (如 Email中, 收到了新的邮件), 直接将该事件推送给客户端, 而无需客户端时时刻刻应用 在线, 或者定时去服务器查看是否有新的事件发生。 Push技术的本质在于让 信息去主动寻找用户,优势在于信息的主动性和及时性,通过使用该技术可尽 快的将信息推送到用户面前。
Push Notification方案的工作机制可以筒单的概括为图 1所示, 其中:
Provider 是指某个 iPhone 软件的应用服务器。 APNS 是 Apple Push Notification Service ( Apple Push服务器) 的缩写, 下文统一使用该缩写。
整个工作过程为:
1、应用服务器( Provider )把要发送的消息、目的 iPhone的标识( notification ) 打包, 发给 APNS。
2、 APNS在自身的已注册 Push服务的 iPhone列表中, 查找有相应标识的 iPhone , 并 4巴消息发到 iPhone。
3、 iPhone把发来的消息传递给相应的应用程序( Client APP ) , 并且按照 设定弹出 Push通知。 APNS判断 Push推送消息该发给哪台 iPhone的依据是一个 "目的 iPhone 的标识", 这个标识就是 device token (设备令牌)。 1、 在 iphone入网后会连接 APNS , 建立连接; 2、 连接完成后, APNS会把设备令牌 (device token)返回给 iPhone; 3 ~ 4、 当 iPhone访问应用服务的时候, 应用客户端把这个令牌发给应 用服务器( Provider )。 后续应用服务器可通过 APNS和该令牌找到用户。 即, 当应用服务器( Provider )有 Push消息要发送时, 就会把对应帐号的设备令牌 (device token)和消息一起发送给 APNS , 而 APNS 再依据设备令牌 (device token), 找到相应的目的 iPhone, 并发送相应的 Push 消息。 以上过程如图 2 所示。
由于 APNS与终端之间存在 NAT和防火墙,如图 3所示, APNS( Apple Push 服务器 )与终端之间需要维持心跳来维持 IP链路可达。
UE入网之后, GGSN为它分配一个私有 IP地址, 而 UE与外界通信, 需 要通过 NAT转换为公有 IP地址。 即外部网元(包括 APNS )所看到的 UE的 IP地址实际上是它的公有 IP地址。
为了接收 Push消息, UE与 APNS进行交互,在 APNS登记所使用的 token 和公有 IP地址的对应关系。 此后, APNS与 UE之间保持用户级的心跳连接, 来保持用户的 IP可达。
由于 APNS看到的用户地址是公有 IP地址,而 NAT机制下终端的公有 IP 地址与私有 IP地址的绑定关系是有时间限制的, 过了一段时间, NAT就会老 化, 终端的公有 IP地址或私有 IP地址会变化, 这样就导致原来的公有 IP地 址与私有 IP地址的绑定关系消失。 为了保证 APNS记录的终端公有 IP地址有 效, 就需要保持 NAT不老化。
发明人发现上述现有技术中至少存在如下明显问题:
该方案需要 APNS和 UE之间的心跳, 来维持 IP连接, 大量心跳信号产 生的信令消息导致网络堵塞, 同时为了维护心跳使得 UE无法进入空闲态, 导 致 UE耗电严重。
进一步的, 上述现有技术只能针对 UE获得了公有 IP地址的情况, 对于 UE没有获得公有 IP地址的情况上述现有技术无法提供 PUSH服务。 发明内容

实施例一 本发明实施例提供一种新的 Push系统架构如图 4所示, 下面是对其中每 个装置的详细说明。
应用 J!良务器 10: 用于发送 Push消息;
在一个实施例中,应用服务 10可以是为用户提供特定应用服务的服务器, 例如 MSN、 QQ Server等。
代理 J ^务器 20: 本发明实施例可能涉及的一种特殊的应用服务器, 用于 代替 UE登入应用服务器 10,支持 Push机制。 UE上的代理客户端获取用户的 应用登录信息, 发送到代理服务器 20, 代理服务器 20使用这些应用登录信息 登录到最终的应用服务器上。 当用户关闭了代理客户端, 代理服务器 20会继 续为用户保持在应用服务器 10上的登录。当应用服务器 10或其他应用用户要 向该用户的应用账户发送消息时, 代理服务器 20会通过 Push的方式, 将消息 推送到用户终端上。
需要说明的是, 代理服务器 20不是图 4架构中的必选装置, 如果应用服 务器 10自身支持 Push服务, 就不需要代理服务器 20。 如果应用服务器 10自 身不支持 Push服务, 则需要代理服务器 20, 在这种情况下, 代理服务器 20 可以和应用服务器 10部署在一个物理实体(如物理的服务器)上, 也可以部 署在单独的物理实体(如物理的服务器)上。 一个代理服务器可以为多个应用 服务器提供代理服务。
应用客户端 30: 应用服务的客户端软件, 例如 MSN、 QQ客户端软件。 Push客户端 40:用于运行 Push客户端软件,发起 Push注册,在收到 Push 消息时, 按照预先的设定完成相应的响应;
在一个实施例中,按照预先的设定完成相应的响应可以包括: 拉起对应的 应用客户端、 或者展示一条通知消息到 UE界面等。
Push server 50: Push JR务器, 它主要完成以下几个方面的功能:
1、 保存用户标识。 所述用户标识可以包括静态标识和动态标识其中的一 种或者两种。 静态标识是用户签约 Push服务或用户初次使用 Push服务时, 运 营商分配给签约 Push服务的用户的标识, 它长期有效, 一个 Push服务签约用 户可拥有一个或多个用户静态标识; 动态标识是 Push客户端每次注册到 Push server时, Push server按用户的需求为用户动态分配的标识, 它有时效性。
需要强调的是, 动态标识是可选的, 如果静态标识可用, 可以完全基于静 态标识来完成所有的业务流程, 这种情况下, Push Server也就不需要为 UE分 配动态标识。 用户标识(包括静态标识和动态标识) 带有用户签约 Push服务 的域信息,例如 username@push.chinamobile.com,应用服务器能够根据用户标 识找到对应的 Push server
2、 保存应用标识。 所述应用标识是指应用服务的标识, 是运营商定义的 应用标识, 使用 Push服务的应用服务必须在运营商处注册, 运营商为该应用 服务分配 Push服务中使用的应用标识。应用服务器下发的 Push消息中应包含 应用标识。
3、 保存用户标识与 UE私有 IP地址的映射关系, 一个用户标识可对应多 个 UE私有 IP地址。
可选地, 还可以保留用户标识与用户 IMSI的映射关系, 特别当 UE没有 获得私有 IP地址的情况下 (如 UE仅仅是附着在无线网络上, 但没有启动互 联网相关的业务, 因此没有分配私有 IP地址) , 则必须保存用户标识与用户 IMSI的映射关系。
4、 接收应用服务器 10下发的 Push消息, 根据用户标识查询 UE的私有
IP地址或者 IMSI等, 根据 UE的私有 IP地址或者 IMSI, 通过 PS域节点将 Push消息转发给 UE。 可选的, 在接收到应用服务器下发的的 Push消息后, Push Server可以首先认证该 Push消息中携带的应用标识, 如果该应用标识是 合法的, 则进行下面的操作。
PS域节点 60:用于提供 UE到 Push server50的连接服务,将 Push消息发 送到 UE。
进一步地, PS域节点根据不同的应用场景分为两类:
第一类 PS域节点在本发明实施例中称为 PS域节点一,所述 PS域节点一 用来作为对外的网关,负责分组网络接入控制和数据路由、 UE的 IP地址分配、 移动性管理和用户数据管理等功能, 在 2G的 GPRS网络和 3G网络中该类节 点称为 GGSN, 后续长期演进网络中称为 P-GW、 或 HA, 在 WiMAX网络中 称为 ASN GW或 HA, 在 3GPP2网络中称为 PDSN或 HA, 其完成的功能是 类似的;
第二类 PS域节点在本专利中称为 PS域节点二,所述 PS域节点二用来作 为 UE接入 PS域的服务网关, 负责鉴权和加密、 移动性管理、 会话控制、 和 数据路由等功能, 在 2G的 GPRS网络和 3G网络中该类节点称为 SGSN, 后 续演进网络中称为 S-GW、 或 MME ( Mobility Management Entity, 移动管理实 体) , 在 WiMAX网络中称为 ASN GW, 在 3GPP2网络中称为 PDSN, 其完 成的功能是类似的。
本发明实施例中, 如果 UE获得了由 PS域节点一分配的私有 IP地址, 则 只需要 PS域节点一就可完成将 Push消息发送到 UE; 如果 UE没有获得私有 IP地址(如 UE仅仅是附着在无线网络上, 但没有启动互联网相关的业务, 因 此没有分配私有 IP地址) , 则需要 PS域节点一和 PS域节点二共同配合工作 来完成将 Push消息发送到 UE。
通过本发明实施例, UE上的 Push客户端在完成 Push注册后可以与 Push server之间断开连接, 避免了传统 Push业务要求的心跳连接和对现有 NAT机 制的更改; 不要求应用客户端始终在线, 而是通过 PS域节点找到该 UE并将 Push消息发送到该 UE,从而能保证用户对 Push消息永久可达, 节省了网络资 源和 UE耗电, 减轻了网络侧信令负担。 实施例二 本发明实施例提供一种新的 Push服务, 交互过程如图 5所示, 在本实施 例中 UE已获得私有 IP地址, 下面是对其中交互过程的详细说明。
在提供 Push服务前, UE需要获得私有 IP地址。 以现有的无线网络 PS 域为例, 当 UE与网络附着后, 向网络请求一个 IP地址,该地址可以为静态或 动态 PDP地址, 静态 PDP地址必须由家乡网络 HPLMN 久分配给 UE, 动 态 PDP地址则可由 HPLMN或 VPLMN动态分配给 UE。
当激活 PDP context时, HPLMN或 VPLMN为 UE分配一个 PDP地址给 UE, 由 PS域节点一负责分配或释放这个动态地址。
为 UE分配的 IP地址是 PS域节点一管理的私有地址, 即前面所述的私有 IP地址。 通常, 该私有 IP地址是按照网段来划分的, 因此根据 UE的私有 IP 地址所属网段即可找到它当前连接的 PS域节点一。
考虑到某些情况下私网地址不能路由, 例如 PS域节点一的网段有重叠, 则需要 Push server与 PS域节点一之间建立 VPN或隧道连接, 保证业务数据 传输。
在提供 Push服务前, Push server还需要获得并保存用户标识。 所述用户 标识可以包括静态标识和动态标识其中的一种或者两种。静态标识是用户签约 Push服务、或用户初次使用 Push服务时,运营商分配给签约 Push服务的用户 的标识, 它长期有效, 一个 Push服务签约用户可拥有一个或多个用户静态标 识; 动态标识是 Push客户端每次注册到 Push server时 , Push server按用户的 需求为用户动态分配的标识,它有时效性。需要强调的是,动态标识是可选的, 如果静态标识可用, 可以完全基于静态标识来完成所有的业务流程, 这种情况 下, Push Server也就不需要为 UE分配动态标识。
在提供 Push服务前, Push server还需要获得并保存应用标识。 所述应用 标识是指应用服务的标识, 是运营商定义的应用标识, 使用 Push服务的应用 服务必须在运营商处注册, 运营商为该应用服务分配 Push服务中使用的应用 标识。
在提供 Push服务前, Push server还需要获得并保存用户标识与 UE私有 IP地址的映射关系, 一个用户标识可对应多个 UE私有 IP地址。
用户在首次使用 Push服务时, Push客户端先向 Push server注册, Push server通过用户静态标识完成对用户的验证。
UE上需要预先配置 Push server的 APN。 每次 Push客户端向 Push server 注册前, UE先将该 APN上 给网络, 网络根据 APN为 UE分配对应的 PS 域节点一; 此后的 Push客户端发送的注册消息将被发到该 PS域节点一上,该 PS域节点一根据 APN找到对应的 Push server, 将注册消息发给 Push Server; Push server处理完注册后, 向 Push客户端返回注册响应消息。 这样注册的过 程即可完成。
一种特殊的场景下会发生串号,即 Push server上保存了用户标识和 UE的 私有 IP地址的对应关系,但 UE的私有 IP地址变了, 并且原来这个私有 IP地 址又被分配给了另外一个 UE,那么当 Push server要向原用户发送 push消息时, 仍旧按照原来的对应关系将 push消息发给原来的私有 IP地址, 则 push消息 将被发给后面得到这个私有 IP地址的 UE上。 为了避免串号, 本发明还要求, 当 UE的私有 IP地址被释放时, 先通知 Push server删除相应的用户标识和私 有 IP地址对应关系的记录。 即, 如果是 UE发起的私有 IP地址释放, 则释放 之前, Push客户端先通知 Push server删除相应的用户标识和私有 IP地址对应 关系的记录; 如果是网络侧发起的私有 IP地址释放, 则 PS域节点一同时通知 Push server删除相应的用户标识和私有 IP地址对应关系的记录。
用户首次使用 Push服务时, 应用客户端向应用服务器注册, 登记用户静 态标识和应用用户名, 应用服务器保存用户静态标识和应用用户名。
UE在通过应用客户端登录应用服务器后, 可退出应用客户端, 与应用服 务器连接中断。 在这个阶段 PS域节点一保持用于应用客户端登录应用服务器 的 pdp context不释放。
Push服务的流程如图 6所示下, 其详细步骤如下:
S601: Push server接收应用服务器下发的 Push消息。
可选的, 在接收到应用服务器下发的的 Push消息后, Push server可以认 证该 Push消息中携带的应用标识, 如果该应用标识是合法的, 则进行下面的 操作。
可选的, 在接收到应用服务器下发的 Push消息后, Push server还可以认 证发送该 Push消息的应用服务器,认证应用服务器可以基于该 Push消息头中 带的应用服务器域名, 根据应用服务器域名来验证; 也可以基于该 Push消息 的源 IP地址来 3全证, 这个 IP地址就是应用 良务器的 IP地址。 如果该应用月良 务器可使用 Push服务, 则进行下面的操作。
上述两个可选的认证步骤, 可以都不执行、 可以执行其中任意一个、 也可 以执行两个。
S602: Push server根据用户标识获得 UE的私有 IP地址。 Push server从 Push消息中获得用户标识, 根据所述用户标识与 UE私有 IP地址的映射关系 获得 UE的私有 IP地址。 可选的, Push server验证 Push消息中用户标识的合 法性。
S603: Push server根据 UE私有 IP地址获得 UE当前连接的 PS域节点一, 并把 Push消息发送给所述 PS域节点一, 以通过所述 PS域节点将 Push消息 发送给 UE。
所述 Push server根据 UE私有 IP地址获得 UE当前连接的 PS域节点一的 方法, 在本实施例前面部分已详细叙述, 在此不再重复。
所述 PS域节点根据 Push消息中的 IP五元组(目的地址、 目的端口、 源 地址、 源端口、 IP版本 )找到对应的 PDP context, 将 Push消息和应用标识放 在该 PDP context上发给 UE。 UE上的 Push客户端检测到有 Push消息到达,提示用户有 Push消息到达, 询问是否查看。若用户选择查看, 则根据应用标识启动对应的应用客户端查看 该信息。 此后, 可能还会进行别的应用服务数据交互。 若用户选择不查看, 则 结束。 或者, UE上的 Push客户端检测到有 Push消息到达, 该 Push消息仅仅 是一个通知类消息, 则仅向用户显示有 Push消息到达, 而不再启动别的应用 客户端。
进一步地, 如果 UE处于空闲状态时, 所述 PS域节点需要发起使用现有 技术中的 paging过程唤醒 UE。 如果所述 PS域节点需要向某个 UE发 push消 息, 而 UE处于空闲状态, 则先 paging唤醒, 再进行后续的 Push消息发送。
通过本发明实施例, UE上的 Push客户端在完成 Push注册后可以与 Push server之间断开连接, 避免了传统 Push业务要求的心跳连接和对现有 NAT机 制的更改; 不要求 UE上的应用客户端始终在线, 而是通过 PS域节点找到该 UE并将 Push消息发送到该 UE,从而能保证用户对 Push消息永久可达, 节省 了网络资源和 UE耗电, 减轻了网络侧信令负担。 实施例三
本发明实施例是在实施例二的基础上进一步的增强所提供一种新的 Push 服务, 其交互过程如图 7所示, 在本实施例中 UE仅附着到网络, 还没有可用 的私有 IP地址, 下面是对其中交互过程的详细说明。
在提供 Push服务前, Push server需要获得并保存用户标识。 在本实施例 中, 用户标识是指静态标识, 是用户签约 Push服务、 或用户初次使用 Push服 务时, 运营商分配给签约 Push服务的用户的标识, 它长期有效, 一个 Push服 务签约用户可拥有一个或多个用户静态标识。
在提供 Push服务前, Push server还需要获得并保存应用标识。 所述应用 标识是指应用服务的标识, 是运营商定义的应用标识, 使用 Push服务的应用 服务必须在运营商处注册, 运营商为该应用服务分配 Push服务中使用的应用 标识。
在提供 Push服务前, Push server还需要获得并保存用户标识与 UE的 IMSI 的映射关系。 即用户在签约 push服务, 或首次使用 Push服务时, 运营商绑定 用户静态标识和 UE的 IMSI。
用户首次使用应用服务时,应用客户端向应用服务器注册,登记用户静态 标识和应用用户名, 应用服务器保存用户静态标识和应用用户名。
Push服务的流程如图 8所示下, 其详细步骤如下:
S801: Push server接收应用服务器下发的 Push消息。
可选的, 在接收到应用服务器下发的的 Push消息后, Push server可以认 证该 Push消息中携带的应用标识, 如果该应用标识是合法的, 则进行下面的 操作。
可选的, 在接收到应用服务器下发的 Push消息后, Push server还可以认 证发送该 Push消息的应用服务器,认证应用服务器可以基于该 Push消息头中 带的应用服务器域名, 根据应用服务器域名来验证; 也可以基于该 Push消息 的源 IP地址来 3全证, 这个 IP地址就是应用 良务器的 IP地址。 如果该应用月良 务器可使用 Push服务, 则进行下面的操作。
上述两个可选的认证步骤, 可以都不执行、 可以执行其中任意一个、 也可 以执行两个。
S802: Push server根据用户标识获得用户的 IMSI。 Push server从 Push消 息中获得用户标识, 根据所述用户标识与用户的 IMSI的映射关系获得用户的 IMSI。 可选的, Push server验证 Push消息中用户标识的合法性。 本实施例中, 所述的用户标识是指静态标识。
S803: Push server根据用户的 IMSI选择 PS域节点,并把 Push消息和 IMSI 发送给所述 PS域节点, 以通过所述 PS域节点将 Push消息发送给 UE。 可选 地, Push server可以通过 CS域路由方法将 Push消息、 应用标识发给 UE。 所述 Push server根据用户的 IMSI选择 PS域节点, 包括如下过程:
Push server向保存用户信息(例如用户的签约信息或位置信息)的服务器 发送查询该 IMSI的网络附着信息的查询消息, 在不同网络中, 保存用户信息 的服务器可以是不同的网络, 在 3GPP网络中是 HLR或 HSS, 在 3GPP2或 WiMAX网络中是 AAA服务器,与异构网络互通的 3GPP网络中也有 AAA服 务器。 本实施例中以 3GPP网络为例, 即 Push Server发携带 IMSI的 SRI for
GPRS消息到 HLR或 HSS查询该 IMSI是否已附着网络(所述 SRI for GPRS 消息参见 3GPP TS 23.060 v700 ) , 如已附着网络, HSS或 HLR将附着的 PS 域节点二返回给 Push server, Push server选择一个能与该 PS域节点二通信的 PS域节点一, 将 Push消息发给选择的 PS域节点一;
或者, Push server在查询消息中增加自己的 APN , HLR或 HSS判断出该
IMSI已附着网络,则根据 APN选择一个 PS域节点一,将所述 PS域节点一信 息 (地址或域名)返回给 Push server。 Push server将 Push消息 (带用户标识 和 IMSI )发给该 GGSN;
或者,运营商已预先设置规则来选择 Push服务对应的 APN,则 Push server 根据该 APN选择一个 PS域节点一, 将 Push消息发给该 PS域节点一。
当然, 如果 Push server查询 HLR或 HSS发现该 IMSI没有附着网络, 则 整个 Push流程结束, 向应用服务器返回失败指示。
进一步地, 在选择了 PS域节点一后, Push server把 Push消息和 IMSI发 送给所述 PS域节点一, 采用如图 9所示的交互过程将 Push消息发送到 UE, 其详细的步骤如图 10所示, 图 9和图 10所描述的过程是以 3GPP网络为例来 说明的, 对非 3GPP网络其执行类似交互功能的节点的名称有所不同, 其交互 的消息的名称也有所不同, 但其交互过程是一致的。 下面是对图 10中每个步 骤的具体的解释:
S1001: PS域节点一收到一个数据包(包含 Push消息和 IMSI ) , 在不同 无线网络中数据包的名称不同, 如 WCDMA网络中为 PDP PDU包。
S1002: PS域节点一向 HLR或 HSS发包含 IMSI的查询消息, HLR或 HSS 如果查到该 IMSI的 UE, 则返回查询结果, 其中包括 IMSI、 PS域节点二的地 址、 终端不可达原因等。
S1003: 如果 PS域节点一查到了 PS域节点二的地址, 并且没有终端不可 达原因、 或终端不可达原因为 no paging response, 并且该 UE有静态的 PDP 地址( IP地址 ) , 则 PS域节点一向 PS域节点二发送 PDU Notification Request (协议数据单元通知请求) 消息, 其中包括 IMSI、 PDP type ( PDP 类型) 、 PDP地址、 APN等; 所述 PDU Notification Request消息用于 PS域节点二向 UE发送 Request PDP Context Activation (请求分组数据协议内容激活 ) 消息, 包括 TI ( Transaction identifier事务标识) 、 PDP type, PDP地址、 APN等。 所述 Request PDP Context Activation 消息用于所述 UE发起 PDP Context activation过程, 生成可用的 PDP Context。
PS域节点二向 PS域节点一返回一个 PDU Notification Response消息作为 收到确认。
S1004: PS域节点一使用所述的 PDP Context把所述收到的数据包发给 所述 UE。 进一步地, 如果该 UE没有静态的 PDP地址( IP地址) , 则步骤 S1003 和步骤 1004可以是如下三种组合中的一种:
组合一:
S1003: 如果 PS域节点一查到了 PS域节点二的地址, 并且没有终端不可 达原因、 或终端不可达原因为 no paging response, 并且该 UE没有静态的 PDP 地址( IP地址 ) , 则 PS域节点一向 PS域节点二发送 PDU Notification Request 消息, 其中包括 IMSI、 PDP type、 PDP地址、 APN等, 其中 PDP地址留空; 所述 PDU Notification Request消息用于所述 PS域节点二向 UE发送 Request PDP Context Activation消息, 包括 ΤΙ ( Transaction identifier事务标识 )、 PDP type, PDP地址、 APN等, 其中 PDP地址为所述 PDU Notification Request消 息中的 PDP地址;所述 Request PDP Context Activation消息用于所述 UE发起 PDP Context activation过程, 申请动态 PDP地址, 生成可用的 PDP Context。
PS域节点二向 PS域节点一返回一个 PDU Notification Response消息作为 收到确认。
S1004: PS域节点一使用所述的 PDP Context把所述收到的数据包发给所 述 UE。
组合二:
S1003: 如果 PS域节点一查到了 PS域节点二的地址, 并且没有终端不可 达原因、 或终端不可达原因为 no paging response, 并且该 UE没有静态的 PDP 地址(IP地址 ) , 则 PS域节点一先为该 UE分配一个动态 PDP地址, 然后 PS域节点一向 PS域节点二发送 PDU Notification Request消息, 其中包括 IMSL PDP type、 PDP地址、 APN等, 其中 PDP地址填写所述的动态 PDP地 址,并且增加一个指示字段,标明这是一个新分的地址; 所述 PDU Notification Request消息用于 PS域节点二向 UE发送 Request PDP Context Activation消息, 包括 Ή ( Transaction identifier事务标识)、 PDP type、 PDP地址、 APN、 指示 字段等, 其中 PDP地址为所述 PDU Notification Request消息的 PDP地址, 其 中指示字段为所述 PDU Notification Request消息的指示字段; 所述 Request PDP Context Activation消息用于所述 UE发起 PDP Context activation过程, 使 用所述 Request PDP Context Activation消息的所述 PDP地址和所述指示字段, 生成可用的 PDP Context。
PS域节点二向 PS域节点一返回一个 PDU Notification Response消息作为 收到确认。
S1004: PS域节点一使用所述的 PDP Context把所述收到的数据包发给所 述 UE。
组合三:
S1003: 如果 PS域节点一查到了 PS域节点二的地址, 并且没有终端不可 达原因、 或终端不可达原因为 no paging response, 并且该 UE没有静态的 PDP 地址( IP地址 ) , 则 PS域节点一向 PS域节点二发送 PDU Notification Request 消息, 其中包括 IMSI、 PDP type、 PDP地址、 APN等, 其中 PDP地址留空, 并且增加一个指示字段, 表明要求发起没有静态 IP地址时的网络侧激活 PDP context流程; 所述 PDU Notification Request消息用于 PS域节点二向 UE发送 Request PDP Context Activation消息 ,包括 TI( Transaction identifier事务标识 )、 PDP type, PDP地址、 APN、 指示字段等, 其中所述 PDP地址为所述 PDU Notification Request 消息中的 PDP 地址, 其中所述指示字段为所述 PDU Notification Request消息的所述指示字段;所述 Request PDP Context Activation 消息用于所述 UE发起 PDP Context activation过程, 使用所述 Request PDP Context Activation消息的所述指示字段申请动态 PDP地址, 生成可用的 PDP Context。
PS域节点二向 PS域节点一返回一个 PDU Notification Response消息作为 收到确认。
S1004: PS域节点一使用所述的 PDP Context把所述收到的数据包发给所 述 UE。
进一步地,UE上的 Push客户端检测到有 Push消息到达,提示用户有 Push 消息到达, 询问是否查看。 若用户选择查看, 则根据应用标识启动对应的应用 客户端查看该信息。 此后, 可能还会进行别的应用服务数据交互。 若用户选择 不查看, 则结束。
通过本发明实施例, UE上的 Push客户端在完成 Push注册后可以与 Push server之间断开连接, 避免了传统 Push业务要求的心跳连接和对现有 NAT机 制的更改; 不要求 UE上的应用客户端始终在线, 而是通过 PS域节点找到该 UE并将 Push消息发送到该 UE,从而能保证用户对 Push消息永久可达, 节省 了网络资源和 UE耗电, 减轻了网络侧信令负担。 实施例四
本发明实施例提供一种新的 Push服务, 交互过程如图 11所示, 在本实施 例中 UE已获得私有 IP地址, 并且应用服务器借助代理服务器来提供 Push服 务。
本发明实施例与实施例二的处理流程基本类似,其差别点在于将实施例二 中的应用服务器替换成了本实施例中的代理服务器,并增加了代理服务器与应 用服务器之间的交互过程。本实施例与实施例二中上述相同的部分不再重复叙 述,下面只是详细描述不同点和增加的代理服务器与应用服务器之间的交互过 程。
UE在通过应用客户端登录代理服务器后,登录信息除了携带应用信息(例 如用户名和密码), 还需用户动态标识。 代理服务器代替用户向应用服务器进 行应用业务的登录, 登录信息携带用户名和密码等应用信息。
代理服务器代替用户在应用服务器保持登录状态 (例如保持心跳连接) 。 应用服务器向用户发 Push消息, 即向代理服务器发消息, Push消息中携 带用户名, 其中用户名是用户的应用层标识。
代理服务器根据用户名找到用户动态标识, 向 Push server发送包含用户 动态标识和应用标识的 Push消息, 这里的应用标识是代理服务的标识。
后续的处理过程和实施例二一样。
通过本发明实施例, UE上的 Push客户端在完成 Push注册后可以与 Push server之间断开连接, 避免了传统 Push业务要求的心跳连接和对现有 NAT机 制的更改; 不要求 UE上的应用客户端始终在线, 而是通过 PS域节点找到该 UE并将 Push消息发送到该 UE,从而能保证用户对 Push消息永久可达, 节省 了网络资源和 UE耗电, 减轻了网络侧信令负担。 实施例五
本发明实施例提供一种新的 Push服务, 交互过程如图 12所示, 在本实施 例中 UE仅附着到网络, 还没有可用的私有 IP地址, 并且应用服务器借助代 理服务器来提供 Push服务。
本发明实施例与实施例三的处理流程基本类似,其差别点在于将实施例三 中的应用服务器替换成了本实施例中的代理服务器,并增加了代理服务器与应 用服务器之间的交互过程。本实施例与实施例三中上述相同的部分不再重复叙 述,下面只是详细描述不同点和增加的代理服务器与应用服务器之间的交互过 程。
用户在 Push服务签约、 或用户时初次使用 Push服务时, 需要向运营商登 记 IMSI, 运营商为用户分配用户静态标识。 Push server保存用户静态标识和 IMSI的对应关系。
UE入网获得 IP地址后, Push客户端将静态标识和 IP地址注册到 Push server, 得到动态标识。 然后应用客户端向代理服务器发起应用登录, 上报应 用登录信息(应用用户名和密码等)和用户动态标识。 代理客户端再用应用登 录信息代替用户登录到应用服务器。
此后, UE退出了代理客户端, 释放了使用的 PDP Context, 没有 IP地址。 当应用服务器向用户发 Push消息时, 它向代理服务器发送带有用户名的
Push 消息, 其中的用户名是用户的应用层标识。 代理服务器根据用户名找到 对应的用户动态标识, 将含有用户动态标识和应用标识发给 Push server , 这个 应用标识是代理服务器的标识。
后续的处理过程和实施例二一样。
通过本发明实施例, UE上的 Push客户端在完成 Push注册后可以与 Push server之间断开连接, 避免了传统 Push业务要求的心跳连接和对现有 NAT机 制的更改; 不要求 UE上的应用客户端始终在线, 而是通过 PS域节点找到该 UE并将 Push消息发送到该 UE,从而能保证用户对 Push消息永久可达, 节省 了网络资源和 UE耗电, 减轻了网络侧信令负担。 实施例六
本实施例提供一种 Push server装置, 如图 13所示, 该装置 1300包括: 交互单元一 1301: 该单元用于接收应用服务器下发的 Push消息。
可选的, 如果应用服务器不支持 Push服务, 该单元则接收由代理服务器 之间转发的应用服务器的 Push消息。
可选的, 在接收到应用服务器下发的的 Push消息后, 所述单元 1301可以 认证该 Push消息中携带的应用标识, 如果该应用标识是合法的, 则进行下面 的操作。
可选的, 在接收到应用服务器下发的 Push消息后, 所述单元 1301还可以 认证发送该 Push消息的应用服务器,认证应用服务器可以基于该 Push消息头 中带的应用服务器域名, 根据应用服务器域名来验证; 也可以基于该 Push消 息的源 IP地址来 3全证, 这个 IP地址就是应用 良务器的 IP地址。 如果该应用 服务器可使用 Push服务, 则进行下面的操作。
