UMB系统中非激活状态下信令和数据绑定分离的方法
技术领域
本发明涉及一种移动通讯技术, 具体说, 涉及一种 UMB ( Ultra Mobile Broadband, 超级移动宽带) 系统中非激活状态下信令和数据分离的方法。 背景技术
在 UMB系统中, 当接入终端( Access Terminal , AT ) 关闭连接时, 或 者 AT与演进基站( Evolved Base Station, eBS )因某种原因失去连接时, eBS 会向 AT的 Route集合中的 eBS、数据附着点( Data Attachment Point, DAP ) 和会话参考控制器(Session Reference Controller, SRNC )分别发送连接关 闭通告消息, Route集合中其他的 eBS将释放分配给 AT的资源, SRNC将 转入寻呼状态, DAP也将进入寻呼状态, 即当接收到有 AT的 IP包时, 就 向 SRNC转发寻呼请求消息, 触发 SRNC实施寻呼过程。 此时, DAP与接 入网关 (Access Gateway, AGW )建立一种随后寻呼用的唯信令绑定关系, AGW关闭所有与 AT有关的其他的绑定关系, 最后, AT进入一种非激活状 态 (UMB系统目前定义为 idle状态) 。
如图 1所示, 是现有的连接关闭流程示意图, 目前规范中正常的连接关 闭流程中,在 AT关闭连接时, eBS是前向链路服务 eBS( Forward Link Serving eBS, FLSE ),且 eBS ( FLSE )、 SRNC和 DAP都在 AT的 Route集合中(图 中没有示出其他 eBS的存在) 。
步骤 101, AT向 eBS ( FLSE )发送连接关闭消息;
步骤 102, eBS向 DAP发送连接关闭通告消息, 并启动定时器 Tnt_ipt; 步骤 103, DAP向 eBS回送连接关闭确认消息, 并进入寻呼状态, 即当 有 AT的数据包或数据通告消息, 就向 SRNC发送寻呼请求消息; eBS—旦 收到该连接关闭确认消息, 则停止定时器 Tnt_ipt;
步骤 104, DAP向 AGW发送唯信令绑定消息, 并启动定时器
Figure imgf000003_0001
步骤 105, AGW向 DAP回送唯信令绑定确认消息, DAP—旦收到该确 认消息, 则停止定时器
Figure imgf000004_0001
步驟 106, eBS向 SRNC发送连接关闭通告消息, 并启动定时器 Tnt_ipt; (该步骤可与步骤 102并行发生。 )
步骤 107, SRNC向 eBS回送连接关闭确认消息,并进入寻呼状态; eBS 一旦收到该连接关闭确认消息, 则停止定时器 Tnpt;
步骤 108, eBS和 Route集合中的其它实体向 AGW发送计费信息, eBS 释放分配给 AT的资源;
步骤 109, AT进入非激活状态。
如图 2所示, 是现有的寻呼过程流程示意图, 当有 AT的数据到达时, 目前规范中的寻呼流程包括如下步骤。
步驟 201 , AT处于非激活状态;
步骤 202, DAP从 AGW接收到 AT的数据或数据通告消息;
步骤 203 , DAP向 SRNC发送寻呼请求消息;
步驟 204, SRNC向 DAP回送寻呼请求确认消息;
步驟 205, SRNC向管理范围内的 eBS (图中示出只存在一个 eBS的情 况)发送寻呼请求消息;
步驟 206, eBS通过空中接口寻呼 AT;
步驟 207, AT收到寻呼信息后, 与 eBS创建 Route, 且 eBS向 SRNC 索取 AT的会话信息;
步骤 208, eBS成为 FLSE, 并通告 DAP和 SRNC;
步骤 209, —旦收到 eBS成为 FLSE的消息, DAP就将 AGW传来的 数据发送到 eBS, 再由 eBS发送给 AT。
这里, 存在的问题是: 在图 1的示例中, 连接关闭时, 承载数据的 DAP 还要负责与 AGW做信令的绑定(参见步骤 104 ) ,代替了承载信令的 SRNC 的角色, 不符合一般数据和信令分离的要求。 这样, 在图 2的示例中, 当有 AT数据到达时, 导致了 DAP回转寻呼请求消息到 SRNC, SRNC还要回送 一个确认消息 (参见步骤 203和 204 ) , 然后, SRNC再发起真正的寻呼过 程。 DAP这种信令和数据职责不分的情况, 不仅增加了 DAP的负担, 而且, 无谓的增加了步骤 203和 204, 使寻呼流程处理效率降低。
