Description

一种支持应用客户端永久在线的方法、 系统及装置 本申请要求于 2011 年 11 月 15 日提交中国专利局、 申请号为 201110360998.2、发明名称为"一种支持应用客户端永久在线的方法、 系统及 装置"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
本发明涉及通信领域, 尤其是一种支持应用客户端永久在线的方法, 系 统及装置。 背景技术
智能终端上有大量 "永久在线" 类的应用, 这种类型的应用通过终端主 动发起的 PULL方式周期性的与服务器主动建立链接, 更新状态, 因而会产 生大量重复的、 短小的 PULL消息, 比如即时消息 IM、 社交网络 SNS、 VOIP 等永久在线应用需要客户端频繁发送 "keep alive" 消息通知服务在线状态; 又例如, IM、 SNS应用需要客户端频繁向服务器 Pull消息更新好友状态; PushMail需要周期性同步、 刷新; iphone4的 iAD广告推送, 定位跟踪服务都 需要耗费大量的通信资源等等。
为了维持应用永久在线,一个或者多个应用服务器至少需要维持与用户 终端间的一条永久链路。终端与一个或者多个应用服务器之间的链路是不稳 定的, 例如链路中间有 NAT、 防火墙, 用户的 IP地址可能变化, 因此需要通 过频繁的心跳维持链路, 并获取用户状态 (呈现信息)。
一般情况下, 终端进行正常的数据通信时, 网络给终端分配专用的物理 信道用于数据的上下行无线传输, 这种状态称之为 DCH ( Dedicated CHannel 专用信道)状态。 当没有数据传输时, 可使终端处理 Idle状态, 在 Idle状态下 所有的链接在接入层都是关闭的, 终端只监听寻呼信息。 因而在 DCH和 Idle 状态下, 终端对于电量的消耗差别非常大。 智能终端基于省电的考虑, 一般 6 ~ 8秒无数据传输, 手机进行 "快速休眠" 强制切换到 Idle状态。 而 "永久 在线" 应用又经常需要与服务端进行心跳联接。 从而导致终端在 Idle状态与 DCH状态间的频繁切换, 从 Idle状态到 DCH激活态转换无线侧需要 32条信令 恢复链接, 这种状态间的频繁切换对无线侧的信令造成重大的冲击。 发明内容

永久在线引擎 A0E (101 ), 位于终端 (10) 中, 与至少两个应用客户端 通信链接;
永久在线服务网关 A0G (20) ,位于网络侧, 与位于网络侧的一个或者多 个应用服务器( 04, 05 )通信链接;
所述永久在线引擎 A0E (101 )和所述永久在线服务网关 A0G (20) , 用于 建立一个长链接, 其中, 所述至少两个应用客户端通过所述长链接分别与所 述一个或者多个应用服务器( 04, 05 )通信;
用户管理服务器(30), 位于网络侧, 与所述永久在线引擎 A0E (101 ) 和所述永久在线服务网关 A0G (20)通信链接, 向所述 A0E (101 )提供路由信 息, 其中, 所述 A0E ( 101 )根据所述路由信息请求建立所述长链接; 用户管 理服务器(30)进一步用于在建立所述长链接的过程中, 向所述 AOG(20)提 供鉴权信息。
上述提到的一个或者多个应用服务器可以包括但不限于提供下述应用 的之一或者任一组合的服务器: PUSH Mail, 天气预报, VOIP, 广告, 定位 服务, 企业办公, 生活服务, 等等。
上述提到的长链接, 可以是符合传输控制协议 ( TCP, Transmission
Control Protocol ) 的长链接, 也可以是符合用户数据报协议 (UDP, UserDatagramProtocol ) 的长链接; 上述用户管理服务器( 30 )可以作为永久在线业务用户数据的管理节点, 向所述 A0E ( 101 )提供路由信息, 以便于所述 A0E ( 101 )根据所述路由信 息请求建立所述长链接; 以及, 在所述 A0E ( 101 )和所述 AOG (20)建立长链 接的过程中, 向所述 A0G (20)提供鉴权信息。 上述方案可以使得该永久在线 引擎 A0E ( 101 )和该永久在线服务网关 A0G (20)能够简便的, 并且安全的建 立该长链接。 需要说明的是, 该用户管理服务器(30 ) 内部可以是集群式, 或分布式; 可以是和网络侧任何可能的设备合设, 或者独立设置的, 但对于 A0G而言是能够与其他设备相区分的, 上述的系统中 A0G可能有多个。
在一个较优的实施方式中, 上述鉴权信息为用户身份信息, 例如手机号 码, 用户标识或者用户名称, 方便各种应用服务器针对其用户进行鉴权, 具 体实施方式中可以由 A0G (20)代理该鉴权的过程。 然而一般的, 终端( 0 1 ) 在通信的过程中携带的是终端身份信息, 例如 IMS I信息, 或者设备标识, 这些信息如果作为鉴权信息, 需要提前与一个或者多个应用服务器等设备进 行复杂的认证交互。 另外需要说明的是, 上述路由信息为用户身份信息所归 属的 AOG (20)的地址, 在具体实施方式中, 对于整个网络, 可能有多个 A0G (20) , 需要明确为某个用户身份信息提供代理服务的 A0G。 参考图 2b , 为一个较优的实施方式的流程图, 前述图 2的系统执行如 下的方法:
201. 用户管理服务器(30 ) (例如注册管理模块(3011) )获取并存储终 端身份信息和用户身份信息的对应关系, 且存储用户身份信息所归属的 A0G (20)的地址; 202. 当 AOE ( 101 ) (如链接管理模块( 1011 ) )发送路由信息请求时, 用户管理服务器( 30 ) (例如路由信息模块( 3012 ) )根据路由信息请求中 的终端身份信息, 以及终端身份信息和用户身份信息的对应关系, 向 A0E ( 101 )提供用户身份信息归属的 A0G的地址;
203. 当 A0G (20)发送鉴权信息请求时, 用户管理服务器( 30 ) (例如鉴 权信息模块(3013) )根据鉴权信息请求中的终端身份信息, 以及终端身份 信息和用户身份信息的对应关系, 向 A0G (20)提供用户身份信息。
具体的, 上述获取并存储终端身份信息和用户身份信息的对应关系的过 程, 可以是在前述长链接未建立之前, 利用其他可能的通信通道实现的, 例 如电路域通信通道,或者短消息通道。具体的,可以包括但不限于由终端( 10 ) 上报给用户管理服务器(30 ), 或者由其他网络设备转发给用户管理服务器 ( 30 ), 也可以是用户管理服务器(30 ) 向终端 (10 )或者其他网络设备请 求的方式得到。 参考图 3a , 较优的, 以由运营商提供的通信系统为例, 并具体以终端 身份信息为 IMSI信息, 用户身份信息为手机号码为例, 上述在建立长链接 的过程中,位于网络侧的用户管理服务器( 30 )向 A0E ( 101 )提供路由信息, 向 A0G (20)提供鉴权信息的过程具体包括:
301 , 所述 A0E ( 101 ) (例如, A0E ( 101 )上的链接管理模块(1011) ) 在所述永久在线引擎 A0E ( 101 ) 启动时或者检测到 SIM卡中的 ISMI信息与 上次注册的信息不同时, 自动发送上报消息到用户管理服务器( 30 ), 所述 上报消息携带所述 IMS I信息和所述手机号码。 上述上报消息是不需要建立好前述的 AOE (101 )和 AOG(20)之间的链路 的情况下能够发送的信息, 例如电路域的信息, 或者非数据链路的信息。 更 具体的, 可以是短信息, 或者, 由 AAA服务器转发的上线 Radius通知等等。 如果为短消息, 则只需要在内容中携带 IMSI信息, 系统将其发送方默认设 置为手机号码, 进一步节约了数据通信资源。
302, 用户管理服务器(30) (如上述注册管理模块(3011) )根据收到 的所述上报消息获取所述 IMSI信息和所述手机号码, 存储所述手机号码和 所述 IMSI信息的对应关系。
303,可选的, 由于上报消息可能有延迟, 为了确保用户管理服务器(30) 收到该上报消息后再进行后续处理流程, A0E ( 101 )可以进行一定的延时。
304, A0E (101 ) (例如链接管理模块(1011) ) 向所述用户管理服务器 ( 30 )发送路由信息请求, 该路由信息请求中携带所述 IMSI信息。
305, 用户管理服务器( 30) (如路由信息模块( 3012) )根据接收到 的路由信息请求中的 IMSI信息查找到对应的手机号码(具体的, 即指查找 上述注册管理模块(3011) ), 再根据预先存储的手机号码归属的 A0G地址, 返回该手机号码归属的 A0G (20)的地址给所述 A0E ( 101 )。
306, A0E ( 101 ) (例如链接管理模块(1011) )获取到归属的 A0G信息 后, 向归属的 A0G (20)发起注册请求, 该注册请求携带 IMSI信息。
较优的, 该注册请求还可以携带但不限于: A0E (101 ) 中的已经注册的 应用客户端的信息, 例如该应用的标识, 终端的型号、 接入网络 APN、 操作 系统版本, 以及 A0E ( 101 ) 的版本等等。
307, 该 A0G (20)收到注册请求后, 接收到所述 A0E (101 ) 的注册请求 后, 判断其中包含的 IMSI信息在该 AOG (20)中是否已经注册。
308,如果没有注册则该 A0G (20)向用户管理服务器(30 )发送鉴权信息 请求, 所述鉴权信息请求携带所述注册请求中的 IMSI信息。
309 , 用户管理服务器(30 )接收到鉴权信息请求后 (具体的, 例如终 端信息模块 301 ) 向 A0G (20)返回 IMSI信息对应的终端信息手机号码。
310, A0G (20) (例如其中的链接管理模块 (2011) )判断是该手机号 码否为该 A0G (20)的服务范围, 如果不是返回注册失败, 流程结束。 如果属 于该 A0G (20)的服务范围, 该 AOG (20) (例如其中的链接管理模块(2011) ) 存储该手机号码。 较优的, 还可以保存前述注册信息中携带的其他信息, 例 如终端型号, 已经注册的应用客户端, 等等信息。
311 , 在 310 中成功注册以后 AOG (20) (例如其中的链接管理模块 (2011) ) 向 (^ ( 101 ) (例如链接管理模块(1011) )返回注册响应。
至此, A0E ( 101 )与归属的 A0G (20)成功建立前述长链接。 该过程利用 了系统中可信任的终端信息, 以及用户信息建立长链接, 不需要系统通过复 杂的交互为每个终端 ( 10 )生成唯一的设备 ID, 并利用该唯一的设备 ID建 立长链接, 从而在简化流程的同时提高了长链接的安全性。 前述图 3a示出的是终端 ( 10 ) 启动时或者检测到 SIM卡中的 ISMI信 息与上次注册的信息不同时(即终端中的 SIM卡被更换,可以理解为一个新 的终端 (10 ) ) 的建立联接的过程, 具体的, 包含终端信息在 AOG(20)上的 注册和应用信息在 AOG(20)上的注册。在其他的情况下,可能出现终端( 10 ) 本身到 AOG(20)注册后, 增加安装或者删除了某些应用, 需要釆取类似的方 法进行应用信息的更新。参考图 3b,为更新应用的流程示意图,其中 AOG(20) 为终端 ( 10 ) 归属地的 AOG和应用服务器接入地的 AOG 所组成的系统。 一个具体例子中, 其流程包括:
301b, 终端上安装 (或者卸载)支持能与 AOE(lOl)交互实现 AOI功能的应 用客户端;
302b, 应用客户端安装完成后 (或者卸载完成后), 调用 SDK的应用登 记接口进行登记(卸载视为调用 SDK的应用注销接口进行注销);
303b, AOE (l Ol)调用 REG接口, 向终端归属地 A0G发送增加应用请求 (卸载时为删除应用请求);
304b, 终端归属地 A0G将终端对应的应用信息更新入库;
305b, 终端归属地 A0G向 A0E (1 01)返回注册响应(卸载时未注销响应 ); 305b, 终端归属地 A0G根据终端上报的应用的 ID, 构造 INFO上线通知 消息, 发送到应用归属的 A0G网关, 该上线通知消息携带手机号码。 (当卸 载时为下线通知消息)。
307b, 应用服务器接入地的 A0G , 将手机号码转换为伪码。
308b, 应用服务器接入地的 A0G , 将上线通知消息(当卸载时为下线通 知消息)转发给应用服务器, 消息中携带伪码。
309b,应用 良务器返回通知响应。
310b,应用服务器接入地的 A0G将通知响应转发给原通知发起方 A0G网 关。
具体的, 当终端归属 A0G网关与应用归属 A0G网关为同一个网关时, 则 不需要上述流程中的第 306b、 310b步的消息在网关间的前转过程。 若终端归属地 AOG网关与应用归属 AOG网关不是同一个网关, 并且二者 之间没有建立有效联接, 则在前转消息前, 由终端归属地 A0G网关主动向应 用归属地 A0G网关完成 REG注册登录过程, 然后再进行消息前转。
为了简化 AOG网关内部对于 REG消息的处理流程,在应用安装流程中, AOG 02可以不区分何种类型的注册消息(或者注销消息), 收到报文后仍可 按首次注册流程,确认 IMSI摘要在本 AOG是否存在,如果不存在到用户管 理服务器 03上查询手机号码,并根据手机号码是否属于本 AOG服务的范围, 确认给 AOE(lOl)返回消息的内容。 只不过在单纯的应用安装流程中, IMSI 必定存在, 号码必定属于本 AOG, 不会走到另外分支。 如图 4a所示为一个支持应用客户端永久在线的系统实施方式的架构示 意图, 系统中包括:
至少两个应用客户端, 该应用客户端位于终端( 10 ) 中, 与所述永久在 线引擎 A0E (101)通信连接;;

其中, 该至少两个应用客户端通过该长链接与该一个或者多个应用服务 器 04通信, 以分别实现该一个或者多个服务器( 04 , 05 )提供的应用业务; 在该系统中, 该长链接的维护由服务侧的 A0G (20)负责, 也就是说, 在终端 ( 10 ) 与 AOG (20)之间, 由 A0G (20)发起心跳消息, 以便于维护该长链接。 其中应用客户端用于面向用户提供应用业务, 应用服务器 04用于提供各种 应用业务,例如下述应用的之一或者任一组合: PUSH Ma i l, 天气预报, VOIP, 广告, 定位服务, 企业办公, 生活服务, 等等。
如图 4a所示, 釆用这种维护长链接的方式, 相对于由终端侧发起心跳 的方式, 一方面终端(含其内的各个应用客户端)不需要向一个或者多个应 用服务器发送大量心跳消息,减少终端侧的信令压力, 另一方面终端内的 A0E (101)也不需要对这些心跳进行过滤 /放弃等特别的处理, 在减少了终端 向外发送的信令消耗的同时, 进一步的减少了终端 (10 ) 内部的信令消耗; 另外, AOG (20)发起心跳时可以根据网络情况调整心跳间隔, 自动控制心跳 参数, 使心跳最符合于网络的情况, 从而避免终端侧主动探测网络参数的过 程, 进一步的减少了通信资源浪费。 参考图 4b, 在较优的实施方式中, AOE (l Ol)和 AOG (20)可以各自分别根 据自己的判断主动地断开该长链接, 从而进一步得以节省网络、 终端、 服务 器等的通信资源, 当然也节省了各设备尤其是终端(10 )的电量消耗。 当有 需要时, A0G (20)可主动再次唤醒与终端侧的连接。 参考图 5a为从 AOE (l Ol)的角度, 关于长链接的心跳维护的实施方式的 示意图。 参考图 5a , 在建立了长链接后, A0E (101)对长链接进行维护的较优 的方法的示意图, 包括: 可选的, AOE (101) (例如其中的链接管理模块 ( 1011 )) 收到 A0G (20) 主动发送的断开请求(例如 BYE), 则断开该长链接。
可选的, AOE(lOl) (例如心跳时间模块( 1012)) 收到心跳消息后, 刷 新定时器, 如果该定时器超过一定的时间阈值的时候还未收到其他心跳消 息, 则向 A0G (20)发送断开请求(例如 BYE), 用以关闭该长链接。 例如, 设 置该时间阈值为 5分钟, 10分钟, 或者 30分钟等等。
可选的, AOE(lOl) (例如其中的应用管理模块(1012))检测到其管理 的所有应用客户端在一定的时间阈值内未运行时, 主动发起断开请求(例如 BYE请求), 则断开该长链接。 例如, 设置该时间阈值为 5分钟, 10分钟, 或者 30分钟等等。
可选的, AOE(lOl) (例如其中的电池监控模块(1014))监视终端(10) 的电池电量, 当电量不足于一定的阈值时 (例如电量仅剩 10%, 或者 5%), 如果长链接存在, 则主动发送断开请求例如 BYE), 可选的, 可以在断开请求 中增加标签, 表明是因为电量低而断开该长链接。
通过前述可能的实施方式, 长链接断开以后, A0E (101)进入休眠状态,
(可以等待 A0G (20)通过短信唤醒), 能够节省终端(10)的电量。 其中, 各 种由 A0E (101)主动发起的断开长链接的方式,进一步的减少了不必要的信令 浪费, 例如断开后网络侧的 A0G (20)不需要再发送心跳消息, 另外也进一步 的节省了终端 (10)上的电池电量。
另外需要说明的是, 当 AOE(lOl)与 AOG(20)之间的长链接存在时, 需要 禁止终端( 10)的操作系统进入休眠状态, 以保证长链接的正常连接, 当与 A0G之间的长链接断开时, 可以恢复操作系统的休眠机制。 参考图 5b, 从 AOG (20)的角度说明如何维护该长链接。 需要说明的是, 图 5b描述的 AOG(20)在实际的应用过程中,可能是单一的一个服务器,可能 根据需要分为终端 (10) (具体的其中的 AOE(lOl) ) 归属的 AOG(20)和一个 或者多个应用服务器归属的 A0G (20)。 其中, 可选的, 对于后者(两个 A0G 的情况),终端( 10 )归属的 A0G (20)和一个或者多个应用服务器归属的 A0G (20) 之间进行通信连接,终端( 10)归属的 A0G (20)负责与终端( 10)中的 AOE(lOl) 交互, 一个或者多个应用服务器归属的 A0G (20)负责与一个或者多个应用服 务器交互。 更为具体的, 从 A0G (20)的内部结构来讲, 图 5b所示的 501到 504可以由终端管理模块(1021)执行, 该终端管理模块(1021)可以位于终端 ( 10) 归属的 AOG(20)上; 步骤 500, 505-508 可以由应用管理模块(1022) 执行, 该应用管理模块(1022)可以位于应用服务器归属的 AOG(20)上。
具体的, 图 5b所示的实施方式中, 包括如下步骤:
500-501, AOE(lOl)与 AOG(20)成功的建立长链接。 其中包括 AOE(lOl) 与终端归属地 AOG完成 REG注册流程(501 ), 包含终端的信息, 以及终端上 应用客户端的信息。 相应的, 一个或者多个应用服务器也需要已经成功的注 册到 AOG(20) (步骤 500 ), 这样, AOE(lOl) (即终端( 10 ))上下线通知后 续能够通知到一个或者多个应用服务器。
502, AOE(lOl)与 AOG(20)成功的建立长链接后, A0G (20)主动向终端发 起 ACK心跳消息, 以便于维护该长链接。 较优的实施方式中, 可以根据网络 的状况配置发送心跳消息的时间间隔, 即心跳间隔, 以及配置超时时间控制 等; 503, AOE(lOl)回复 ACKRSP响应, 表示 AOE (101)处于的活动状态。
504, A0G (20)根据下面几种情况对长链接进行维护, 包括但不限于: 5041, 当 AOG(20)接收到 AOE (101)主动发送的断开请求时, 断开该长 链接, 不再发送心跳消息; 具体的, 可以参考图 5a所示的流程。
5042, 当 AOG(20)判断超过一定时间阈值没有收到从该终端 ( 10 )
(AOE(lOl) )发送的数据流, 主动发起断开请求(例如 BYE), 不再发送心跳 消息。 较优的实施方式中, 该时间阈值可配置, 例如, 默认 5分钟, 10分钟 或者 30分钟。
5043, 当 AOG(20)判断发送心跳消息 ACT后, 没有得到 AOE(lOl)的响 应的情况超过一定的次数阈值时, 主动发起断开请求(例如 BYE ), 不再发送 心跳消息。 较优的实施方式中, 该次数阈值可配置, 例如, 默认为 3次, 4 次或者 5次等等。
5054, 图中未示出, 502后, 如果既未收到 A0E (101)发送的断开请求也 未主动向 A0E (101)发送断开请求,则根据心跳时间间隔,规律的向 AOE(lOl) 发送心跳消息, 以便于保持该长链接。
较优的实施方式中, 在前述针对长链接的维护的基础上, AOG(20) (例 如应用管理模块(2012))还可以进一步的对 A0E (101)的在线状态, 以及该 AOE(lOl)上的应用客户端进行管理。 例如, 可选的, 505, 如果 AOG(20)根据 步骤 5041, 5042, 或者 5043等情况断开该长链接, 则确认 AOE (101)已经离 线, 更新本地存储的 A0E (101)的是否在线状态为: 离线。
可选的, 506, AOG(20)查询 AOE(lOl)上注册的永久在线的应用客户端信 息, 如果和一个或者多个应用服务器之间需要使用伪码进行交互,则 AOG(20) (例如应用管理模块 ( 2012 ) )将 AOG (20)上存储的该 A0E (101)的手机号码 转换为伪码, 该伪码用于在 AOG (20)和应用服务器之间作为用户身份信息进 行传递。这里,伪码是一个用户在系统内部针对某一个应用的唯一身份标识。
具体的, 为了保护用户隐私, 有些应用不能把手机号码透露给应用服务 器(SP ), 这时需要用其它的标识来代替手机号码。 一般做法为根据用手机 号码和其它随机数这些信息做一个摘要, 计算出的摘要可称之为伪码。 手机 号码与伪码是一一对应的,映射关系可以保留在服务器侧。但算法是单向的, 也就是说相关的随机参数不会发送给应用服务器( SP ),因而应用服务器( SP ) 通过伪码不能反推出手机号码。 一个或者多个应用服务器(SP )发送下行消 息时可以通过伪码来标识用户,在服务器侧例如可由伪码查询出对应的手机 号码, 则消息可路由到正确的用户。
更具体的, 伪码是应用级别的, 可指定某些应用启用伪码功能, 某些应 用关闭伪码功能。 若应用管理模块(2012 )在应用的控制属性中指定了需要 传递伪码, 则需要为与此应用有交互的手机号码生成伪码, 以及, 维护用户 手机号码与伪码的对应关系。 一个例子中, 生成的伪码的方法为: 伪码 = HASH (MSISDN, Time, APPID、 Random)其中: HASH为哈希算法, 例如釆用 MD5 算法; MSISDN为用户手机号; Time: 时间戳, 例如釆用 YYYYMMDDHH24MISS 格式; APPID为应用标识; Random为随机数。 对于指定的手机号码与某个应 用, 伪码在系统中只生成一次, 终生有效。 具体的, 当需要由手机号码转换 成伪码时, 系统首先根据手机号码及应用 ID做联合查询本地数据库, 查不 到伪码, 则证明是首次使用该应用, 则用上述算法生成伪码。 当需要由伪码 到手机号码的转换时, A0G (20)查询本地数据库, 查询失败, 则证明应用指 定的伪码错误。 查询成功时, 将应用消息中的 APPID 与本地伪码数据库的 APPID进行匹配, 匹配成功, 则认为伪码校险成功。 可选的, 507 AOG(20)构造下线通知消息发给一个或者多个应用服务器, 该下线通知消息中包含伪码。
相应的, 508, —个或者多个应用服务器收到下线通知消息后可以返回 通知响应。
具体的, 如果 A0G (20)是一个服务器, 则, 该 A0G (20)自己执行上述步 骤 506, 507; 如果 AOG(20)是 AOE(lOl)归属的 AOG(20)和一个或者多个应用 服务器归属的 AOG(20)组成的系统, 则 AOE(lOl)归属的 AOG(20)发送包含手 机号码的下线通知消息给一个或者多个应用服务器归属的 AOG(20), 由一个 或者多个应用服务器归属的 A0G (20)将该手机号码转换为伪码, 将包含伪码 的下线通知消息发送给一个或者多个应用服务器。 基于上述各种可能的实施方式, 在长链接断开以后, AOE(lOl)可以等待
AOG(20)通过短信唤醒, 重新建立起该长链接。 具体的可以由如图 6 所示的 系统实现, 例如是 AOG(20)中的 "短信推送模块(2015)", AOE(lOl)中的 "短 信处理模块(1013)", "应用唤醒模块(1015)" 等来实现。 具体的, 参考图 7 a为长链接断开的情况下可能的唤醒该长链接的实施 方式的流程示意图。 包括:
7 0 1 , A0G (20)中的短信推送模块 (2015)在特殊情况下向 AOE(lOl) 发送 "唤醒短信", 用于唤醒尚未建立或者已经断开的长链接。
具体的,唤醒短信不是普通的文本短信,是一种特殊格式的二进制短信, 在 AOG (20)和 AOE (l Ol)之间约定, 二者可理解, 其它网络设备不可见。 这种 用于唤醒长链接的二进制短信,可能包括需要唤醒的应用 ID, 下行消息发送 方标识, 目的用户标识, 消息的摘要等内容。
7 0 2 , A0E (101)中的短信处理模块(1013 )监听、拦截到 "唤醒短信" 后, 解析该 "唤醒短信"触发 A0E (101)中的链接管理模块( 1011 )建立长链 接; 具体的, 监听是监测到有唤醒短信存在, 拦截是指唤醒短信不再向下传 递, 其它应用不会再收到唤醒短信内容。
7 0 3 - 7 0 4 , A0E (101)中的链接管理模块( 1011 )根据短信处理模 块(1013 ) 的提示向 AOG (20)发起注册请求, 以及接收 A0G (20)返回的注册 响应, 相应的建立起该长链接, AOG (20)将应用服务器发送的下行消息通过 前述重新建立的长链接发送给 A0E (101) 。 在另一个较优的实施方式中,参考图 8,一个唤醒应用客户端的方法实施 方式的流程示意图, 在长链接已经建立或者已经被唤醒, 但是终端(10)中的 应用客户端已经退出, 但是接收到了 A0G (20)转发的发送给该应用客户端的 数据时(801 ), A0E (101)中应用唤醒模块(1015 )还可以拉起该已经退出的 应用客户端 ( 802 )。
具体的, 应用客户端与 AOE (l Ol)在终端( 10 )上是两个独立的进程, 应 用启动时需要向 AOE (l Ol)注册, 告知 A0E (101)其程序安装位置、 运行参数 等信息, A0E (101)得以监控终端上应用客户端的运行状态。 当应用客户端退 出 (可能是根据用户的指令主动退出), 又有下行消息需要通知到该应用客 户端时, A0E (101)根据前面的注册信息, 重新运行客户端的程序, 从而拉起 该应用客户端, 然后通过内部的 API接口或消息接口将收到的下行消息通知 到该应用客户端。 在其他的实施方式中, 可以提供不同的可以与上述各实施方式进行任一 组合的进一步的实施方式, 参考图 6 , 可选的, AOE (101)、 A0G (20) , 用户 管理服务器(30 ) 包含多种可能的模块, 各模块之间除非逻辑上有排斥, 将 可以进行任意的组合, 从而形成更优的实施方式。 下文将对各装置, 以及装 置中的各模块一一进行介绍。 图 9为系统中终端(10)的一个实施方式的结构示意图。 终端(10)—般包 括至少一个处理器(102) (例如 CPU ),至少一个网络接口(105)或者其他通信 接口, 存储器(106) , 和至少一个通信总线(103) , 用于实现这些装置之间的 连接通信。 处理器(102)用于执行存储器中存储的可执行模块, 例如计算机 程序; 终端(10)可选的包含用户接口(104) , 包括但不限于显示器, 键盘和 点击设备(例如, 鼠标, 轨迹球( t rackba l l ) , 触感板或者触感显示屏。 存储器(106)可能包含高速 Ram存储器, 也可能还包括非不稳定的存储器 ( non-volat i le memory ), 例如至少一个磁盘存储器。 通过至少一个网络接 口 (可以是有线或者无线)实现该终端(10)与至少一个其他计算机之间的通 信连接, 可以使用互联网, 广域网, 本地网, 城域网等。
