Description

空闲模式控制方法、 基站及终端 技术领域 本发明涉及通信领域, 具体而言, 涉及一种空闲模式控制方法、 基站及 终端。 背景技术 全球微波接入互通 ( World Interoperability for Microwave Access, 简称为 WiMAX ) 是一项基于 IEEE 802.16 协议的宽带无线接入城 i或网技术
( Broadband Wireless Access Metropolitan Area Network )。 随着技术的发展 , WiMAX通信系统中所釆用的 IEEE 802.16e协议演进为 IEEE 802.16m协议, 并且出现了支持不同协议的基站和终端, 例如: 先进基站 ( Advanced Base Station, 简称为 ABS )、 标准基站、 先进终端 ( Advanced Mobile Station, 简 称为 AMS )、标准终端。先进基站是指既能支持新的 16m协议、又能兼容 16e 协议的基站; 标准基站是指只能支持 16e协议的基站; 先进终端是指既能支 持新的 16m协议、 又能支持 16e协议的终端; 标准终端是指只能支持 16e协 议的终端。
16e协议规范了空闲模式( Idle Mode ), 空闲模式的目的在于减少终端的 能量消耗、 降低对服务基站空口资源的占用。 终端进入空闲模式后, 仅仅在 离散的时间间隔周期性地接收基站发送的下行广播数据 (包括寻呼消息和多 播、 广播业务数据等), 并且在穿越多个基站的移动过程中, 不需要进行切换 和网络重新进入操作。 16m协议继承了 16e的空闲模式。 根据相关技术, 终端和基站均可发起空闲模式, 以下将以 16e为例来描 述终端和基站发起空闲模式的操作。 终 端 发 起 空 闲 模 式 时 , 向 基 站 发 送 去 注 册 请 求 码 ( De-registration_Request_Code M直为 0x01的去注册请求消息 ( Deregistration Request, 简称为 DREG-REQ ), 同时启动定时器 T45 , 等待基站响应去注册 命令消息 (Deregistration Command,简称为 DREG-CMD )。 如果在 T45超时 前收到了来自基站的 DREG-CMD 消息, 则进入空闲, 基站在发送 DREG-CMD 消 息 时 , 开 启 管 理 资 源 保 持 定 时 器 ( Management Resource Holding Timer , 简称为 MRHT ), 在该定时器超时 后释放终端连接信息。 基站发起空闲模式时, 向终端发送动作码 ( Action Code ) 为 0x05 的 DREG-CMD消息, 要求终端进入空闲模式, 同时启动定时器 T46和 MRHT。 终端在接收到 DREG-CMD消息后, 发送 De-registration_Request_Code值为 0x02 的 DREG-REQ 消息作为响应, 并且进入空闲模式。 终端也可以发送 De-registration_Request_Code值为 0x03的 DREG-REQ消息来拒绝进入空闲, 此时, 表明终端还有上行数据需要发送, 暂时不进入空闲。 如果基站在 T46 超时前接收到 De-registration_Request_Code值为 0x02的 DREG-REQ消息, 则其将在 MRHT超时后释放终端连接信息。基站侧设置一个去注册命令重试 计数器 ( DREG command retry count ), 基站每发送一次 DREG-CMD消息, 该计数器的加一, 如果达到该计数器的预设值时, 基站还未接收到来自终端 的 DREG-REQ消息,基站将不再发送 DREG-CMD消息, 并释放终端的连接 信息。 釆用上述方法发起空闲模式时, 可能会产生如下问题: Action Code 为
0x05 的 DREG-CMD 消息无可以用于对 De-registration_Request_Code值为 0x01的 DREG-REQ消息的响应, 又可以用于基站主动发起的空闲模式, 这 样, ^口果终端发送 De-registration_Request_Code值为 0x01的 DREG-REQ消 息的同时基站发送了 Action Code为 0x05的 DREG-CMD消息, 则终端接收 到该消息后, 将无法判断基站的目的: 一方面, 如果终端认为基站发送的是 响应消息, 则终端在接收到该消息后将直接进入空闲, 而如果实际上基站是 主动发起空闲, 则基站将接收不到终端发送的 De-registration_Request_Code 值为 0x02或者 0x03的 DREG-REQ消息,并将持续发送 Action Code为 0x05 的 DREG-CMD消息, 直到 DREG command retry count耗尽; 另一方面, 如 果终端认为 是基站 主动发起的 空 闲 模式 , 则 终端 将发送 De-registration_Request_Code值为 0x02的 DREG-REQ消息进行响应, 而如 果实际上基站发送的该消息是对终端的响应, 基站将接收到不期待的 DREG-REQ消息。
16m中也存在着类似的问题。 目前, 相关技术中规定当终端和基站同时 发起空闲模式, 即, 终端发送 De-registration_Request_Code 值为 0x01 的 DREG-REQ消息的同时基站发送了 Action Code为 0x05的 DREG-CMD消息 时, 终端 ^!夺忽略自己的请求, 并响应基站 De-registration_Request_Code值为 0x02的 DREG-REQ消息, 基站也将忽略终端的请求。 但是, 实际上, 终端 无法区分接收到的 Action Code为 0x05的 DREG-CMD消息是否是基站用于 发起空闲模式的消息, 也就无法进行忽略自己的请求这一操作, 可见, 目前 的规定在终端和基站同时发起空闲模式时无法避免操作的混淆。 发明内容 针对相关技术中存在的由于定义不清晰带来的终端和基站的操作的混淆 问题而提出本发明, 为此, 本发明的主要目的在于提供一种空闲模式控制方 法、 基站及终端, 以解决上述问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种空闲模式控制 方法。 才艮据本发明的空闲模式控制方法包括:基站向终端发送去注册命令消息, 并在去注册命令消息中携带用于指示去注册命令消息的类型的控制信息; 其 中, 去注册命令消息的类型包括: 基站主动发起空闲模式的消息、 基站对终 端的去注册请求消息的响应消息。 优选地, 控制信息是动作码和 /或标识信息, 基站通过对动作码和 /或标 识信息设置不同值来指示去注册命令消息的类型。 优选地, 控制信息是请求时长参数, 基站通过是否在去注册命令消息中 包含请求时长参数、 以及在包含请求时长参数的情况下请求时长参数的不同 取值来指示去注册命令消息的类型。 优选地, 当去注册命令消息不包含请求时长参数时, 去注册命令消息为 基站主动发起空闲模式的消息; 当去注册命令消息包含请求时长参数且请求 时长参数为零时, 去注册命令消息为对终端的去注册请求消息的响应消息; 当去注册命令消息包含请求时长参数且请求时长参数为非零时, 去注册命令 消息用于通知终端在请求时长之后发起空闲模式。 为了实现上述目的, 根据本发明的一个方面, 提供了一种空闲模式控制 方法。 才艮据本发明的空闲模式控制方法包括:终端向基站发送去注册请求消息, 并启动定时器;如果终端在定时器超时前接收到基站发送的去注册命令消息, 则确定去注册命令消息是基站主动发起空闲模式的消息; 如果终端在定时器 超时后接收到基站发送的去注册命令消息, 则确定去注册命令消息是对终端 发送的去注册请求消息的响应消息。 优选地, 定时器的时长由基站预先设置并通知终端。 为了实现上述目的, 根据本发明的一个方面, 提供了一种空闲模式控制 方法。 根据本发明的空闲模式控制方法包括: 终端接收来自基站的去注册命令 消息; 终端向基站发送通知消息, 其中, 通知消息的类型指示终端对基站发 送的去注册命令消息类型的判断。 优选地, 通知消息是确认消息, 在终端向基站发送通知消息之前, 方法 还包括: 终端判断去注册命令消息是对终端发送的去注册请求消息的响应; 或者, 通知消息是响应消息, 在终端向基站发送通知消息之前, 方法还包括: 终端判断去注册命令消息是基站主动发起空闲模式的消息。 为了实现上述目的, 根据本发明的另一个方面, 提供了一种基站。 根据本发明的基站包括: 配置模块, 用于在去注册命令消息中配置用于 指示去注册命令消息的类型的控制信息, 其中,去注册命令消息的类型包括: 基站主动发起空闲模式的消息、 基站对终端的去注册请求消息的响应消息; 发送模块, 用于向终端发送经配置模块配置后的去注册命令消息。 为了实现上述目的, 居本发明的又一个方面, 提供了一种终端。 根据本发明的终端包括: 发射器, 用于向基站发送去注册请求消息; 接 收器, 用于接收来自基站的去注册命令消息; 控制器和定时器, 其中, 控制 器在发射器发送去注册请求消息的同时启动预先设置的定时器; 判决器, 用 于根据接收器接收到去注册命令消息的时刻确定去注册命令消息的类型, 其 中, 如果接收器在定时器超时前接收到去注册命令消息, 则确定去注册命令 消息是基站主动发起空闲模式的消息; 否则, 确定去注册命令消息是对终端 发送的去注册请求消息的响应。 为了实现上述目的, 居本发明的又一个方面, 提供了一种终端。 根据本发明的终端包括: 接收模块, 用于接收来自基站的去注册命令消 息; 发送模块, 用于向基站发送通知消息, 通知消息用于通知基站终端进入 了空闲模式。 通过本发明, 釆用在去注册命令消息中携带用于指示其类型的控制信息 的方法, 或通过定时器判断去注册命令消息类型, 解决了由于现有技术定义 不清晰带来的终端和基站的操作的混淆问题, 能够使终端获知去注册命令消 息的类型, 方便了后续的处理。 本发明的其它特征和优点将在随后的说明书中阐述, 并且, 部分地从说 明书中变得显而易见, 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特别指出的结构来实 现和获得。 附图说明 附图用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与本 发明的实施例一起用于解释本发明, 并不构成对本发明的限制。 在附图中: 图 1是根据现有技术的终端发起空闲模式的流程图; 图 2是根据现有技术的基站发起空闲模式的流程图; 图 3是根据本发明方法实施例一的空闲模式控制方法的流程图; 图 4是 居本发明实例 1空闲模式控制方法的具体实施示意图; 图 5是根据本发明实例 3空闲模式控制方法的具体实施示意图; 图 6是 居本发明实例 5空闲模式控制方法的具体实施示意图; 图 7是根据本发明实施例四的空闲模式控制方法的流程图; 图 8是根据本发明实施例五的空闲模式控制方法的流程图; 图 9是根据本发明实施例六的空闲模式控制方法的流程图; 图 10是根据本发明装置实施例一的基站的结构框图; 图 11是才艮据本发明装置实施例二的终端的结构框图; 图 12是才艮据本发明装置实施例三的终端的结构框图。 具体实施方式 以下结合附图对本发明的优选实施例进行说明, 应当理解, 此处所描述 的优选实施例仅用于说明和解释本发明, 并不用于限定本发明。 考虑到相关技术中基站可以主动发送去注册命令消息给终端, 或者也可 以响应于终端发送的去注册请求消息发送去注册命令消息给终端以指示终端 进入空闲模式, 但终端无法对接收到的去注册命令消息类型进行区分, 在以 下实施例中提供了空闲模式控制方案, 包括: 基站向终端发送携带有用于指 示所述去注册命令消息类型的控制信息的去注册命令消息, 或终端在发送去 注册请求消息的同时启动定时器, 借助定时器判断接收到的去注册命令消息 的类型, 优选地, 还可以通过比较时间阈值与发送去注册请求消息及接收到 去注册命令消息之间的时间间隔确定去注册命令消息的类型。 其中, 用于指 示去注册命令消息类型的控制信息可以为以下之一: 通过动作码取值的不同 指示去注册命令消息类型、 通过标识信息取值的不同指示去注册命令消息类 型、 通过请求时长参数指示去注册命令消息类型。 以下通过不同的实施例进 行说明。 方法实施例一 在该实施例提供了一种空闲模式控制方法, 图 3示出了根据本发明方法 实施例一的空闲模式控制方法的处理流程, 如图 3所示, 该方法包括以下步 骤: 步骤 S302,基站在去注册命令消息中携带用于指示该去注册命令消息的 类型的控制信息, 其中, 去注册命令消息的类型包括: 基站主动发起空闲模 式的消息、 基站对终端的去注册请求消息的响应消息。 步骤 S304, 基站向终端发送该去注册命令消息。 实施例一 在该实施例中, 去注册命令消息中携带的控制信息为动作码, 基站通过 动作码的不同取值来指示去注册命令消息的类型, 在实际应用中, 可以在去 注册命令消息中釆用不同的动作码对不同的动作进行区分, 基站将包含该动 作码的去注册命令消息发送给终端, 终端 居收到的去注册命令消息中的动 作码进行相应的处理。 具体地, 需要区分的动作包括: 基站对终端的去注册 请求消息的响应和基站主动发起的空闲模式。 下面以 802.16m系统为例, 结合具体实例对实施例一提供的方法进行举 例说明。 实例 1 图 4示出了才艮据本发明实例 1空闲模式控制方法的具体实施示意图, ABS 在 AAI-DREG-CMD消息中使用不带有请求时长 REG-Duration参数且 Action code为 0x05表示主动发起空闲模式, 使用 Action code为 0x07表示对 AMS 发送的 De-registration_Request_Code值为 0x01的 AAI-DREG-REQ的响应。
AMS发起空闲模式时, 向 ABS发送 De-registration_Request_Code值为 0x01 的 AAI-DREG-REQ 消息, 同时启动定时器 T45 , 等待 ABS 响应 AAI-DREG-CMD。 如果在 T45超时前收到了 Action code为 0x07的 AAI-DREG-CMD消息, 则该消息为 ABS的响应消息, AMS进入空闲, 基站在发送 Action code为 0x07 的 AAI-DREG-CMD 消 息 时 也 ^ 1 开 启 Management Resource Holding Timer , 在该定时器超时后释放终端连接信 息。如果 AMS在 T45超时前收到了 Action code为 0x05的 AAI-DREG-CMD 消息, 且该消息中不带有 REG-Duration参数, 则该消息为 ABS主动发起的 空闲模式, AMS将忽略自己的请求, 发送 De-registration_Request_Code值为 0x02 的 AAI-DREG-REQ 消息进行响应, 并进入空闲模式。 ABS 发送 AAI-DREG-CMD消息的同时开启了定时器 T46和 MRHT, 如果在 T46超时 前) 到 De-registration_Request_Code值为 0x02的 AAI-DREG-REQ消息, 则 ABS认为 AMS进入空闲, 在 MRHT到达时释放 AMS的连接信息。 该方法 的去注册命令消息参数实例如表 1所示。 表 1

买施例二 在该实施例中, 去注册命令消息中携带的控制信息是标识信息, 基站通 过对标识信息设置不同取值来指示去注册命令消息的类型。 具体地, 基站可 以在去注册命令消息中加入去注册用途标识, 该标识取值为零表示是对终端 的去注册请求消息的响应, 该标识取值为 1表示是主动发起的空闲模式, 反 之亦可; 或者, 基站也可以在去注册命令消息中加入消息传输标识, 该标识 取不同的值, 表示基站进行不同的动作。 基站将包含去注册用途标识或者消 息传输标识的去注册命令消息发送给终端, 终端根据收到的去注册命令消息 中的去注册用途标识或者消息传输标识的具体取值进行相应的处理。 下面以 802.16m系统为例, 结合具体实例对实施例二提供的方法进行举 例说明。 实例 3 图 5示出了才艮据本发明实例 3空闲模式控制方法的具体实施示意图, ABS 在 AAI-DREG-CMD消息中 Action code为 0x05时增加 1个去注册用途标识 ( DREG Usage Identifier ),长度为 1比特,当该标识取值为 0时,表示对 AMS 发送的 De-registration_Request_Code值为 0x01的 AAI-DREG-REQ的响应, 当该标识取值为 1 时表示主动发起空闲模式, 当不携带此标识且带有 REG-Duration参数时表示允许终端在该时间段后发起空闲模式。
AMS发起空闲模式时, 向 ABS发送 De-registration_Request_Code值为 0x01的 AAI-DREG-REQ消息, 同时启动定时器 T45 , 等待 ABS响应。 如果在 T45超时前收到了 Action code为 0x05、 DREG Usage Identifier 为 0的 AAI-DREG-CMD消息, 则该消息为 ABS的响应消息, AMS进入空 闲 , 基 站 在 发 送 AAI-DREG-CMD 消 息 时 开 启 Management Resource Holding Timer , 在该定时器超时后释放终端连接信 息。 如果在 T45超时前收到了 Action code为 0x05、 DREG Usage Identifier 为 1的 AAI-DREG-CMD消息,则该消息为 ABS主动发起的空闲模式, AMS 忽略自 己的请求, 发送 De-registration_Request_Code 值为 0x02 的 AAI-DREG-REQ 消 息进行响应 , 并进入空 闲模式。 ABS 发送 AAI-DREG-CMD消息的同时 开启了定时器 T46和 Management Resource Holding Timer, 口果在 T46 超时前) 到 De-registration_Request_Code值为 0x02的 AAI-DREG-REQ消息, 则 ABS认为 AMS进入空闲, 在 Management Resource Holding Timer到达 时释放 AMS的连接信息。 该方法的去注册命令消息参数实例如表 3所示。 表 3

(transaction ID)。 例如, 可以定义该标识取不同 的值时分别表示对 0x01 的 AAI-DREG-REQ的响应、 主动发起空闲模式和允许终端在 REQ-Duration后 发起空闲模式; 或者, 可以定义对 0x01的 AAI-DREG-REQ的响应和主动发 起空闲模式携带不同的 transaction ID,允许终端在 REQ-Duration后发起空闲 模式的情况不携带 transaction ID。 后续的操作大致与实例 1-3中相应的操作相同, 在此不再赞述。 实施例三 在该实施例中, 去注册命令消息中携带的控制信息是请求时长参数, 基 站通过是否携带请求时长参数、 以及在携带请求时长参数的情况下, 请求时 长参数的不同取值来指示去注册命令消息的类型, 当去注册命令消息不包含 请求时长参数时, 去注册命令消息为基站主动发起空闲模式的消息; 当去注 册命令消息包含请求时长参数且请求时长参数为零时, 去注册命令消息为对 终端的去注册请求消息的响应消息; 当去注册命令消息包含请求时长参数且 请求时长参数为非零时, 去注册命令消息用于通知终端在请求时长之后发起 空闲模式。 在实际应用中, 基站将包含请求时长参数的去注册命令消息发送 给终端, 终端根据收到的去注册命令消息中携带的请求时长参数的具体取值 进行相应的处理。 下面以 802.16m系统为例, 结合具体实例对实施例三提供的方法举例说 明。 实例 5 图 6示出了根据本发明实例 5空闲模式控制方法的具体实施示意图。 ABS 在 AAI-DREG-CMD消息中定义: 当消息中没有 REQ-Duration时是 ABS主 动发起的空闲模式, 当 REQ-Duration 取值为零是表示对 0x01 的 AAI-DREG-REQ的响应, 当 REQ-Duration取值不为零时表示通知 AMS在 REQ-Duration设定的时间段后发起空闲模式。 后续的操作大致与实例 1-3中相应的操作相同, 在此不再赞述。 实例 6
ABS在 AAI-DREG-CMD消息中定义: 当消息中没有 REQ-Duration时 是对 0x01的 AAI-DREG-REQ的响应, 当携带 REQ-Duration且取值为零是 表示 ABS主动发起的空闲模式, 当携带 REQ-Duration且取值不为零时表示 通知 AMS在 REQ-Duration设定的时间段后发起空闲模式。 后续的操作大致与实例 1-3中相应的操作相同, 在此不再赞述。 方法实施例二 实施例四 本发明实施例提供了一种空闲模式控制方法, 图 7示出了根据本发明实 施例四的空闲模式控制方法的处理流程,如图 7所示,该方法包括以下步骤: 步骤 S702, 终端向基站发送去注册请求消息, 并启动定时器, 该定时器 的时长是由基站预先设置并通知终端的, 该时长也称时间常量; 步骤 S704, 如果终端在定时器超时前(即, 响应时间常量之内)接收到 基站发送的去注册命令消息, 则确定去注册命令消息是基站主动发起空闲模 式的消息,该动作是基站主动发起的进入 idle;如果终端在定时器超时后(即, 预先设置的响应时间之后)接收到基站发送的去注册命令消息, 则确定去注 册命令消息是对终端发送的去注册请求消息的响应。 实施例五 也可以釆用预先设置时间阈值的方法来确定去注册命令消息的类型。 图 8示出了才艮据本发明实施例五的空闲模式控制方法的处理流程,如图 8所示, 该方法包括以下步 4聚: 步 4聚 S802, 基站预先设置时间阈值, 并通知终端; 步骤 S804, 基站向终端发送去注册命令消息; 步骤 S806,终端通过对其接收到去注册命令消息与其发送去注册请求消 息之间的时间间隔以及时间阈值进行比较, 来确定去注册命令消息的类型, 如果时间间隔小于时间阈值, 则基站发送的去注册命令消息是基站主动发起 空闲模式的消息, 否则, 基站发送的去注册命令消息是对去注册请求消息的 响应消息, 即, 终端根据从发送去注册请求消息到收到去注册命令消息的时 间间隔与预先设置的响应时间常量比较, 从而进行相应的处理。 下面以 802.16m系统为例, 结合具体实例对实施例四及实施例五提供的 方法进行详细的描述。 实例 7
ABS设定一个 AAI DREG-CMD消息接收常量 ( DREG Receive Time ), 即时间常量, AMS发送 0x01的 AAI_DREG-REQ后, 将开启定时器 T45来 等待来自 ABS 的响应消息, 如果在发送 AAI DREG-REQ 的时刻到 AAI DREG-CMD Receive Time时间段内收到 0x05的 AAI DREG-CMD, 终 端将认为是基站主动发起的进入 idle,如果在 AAI_DREG-CMD Receive Time 之后收到 0x05的 AAI DREG-CMD,终端认为是对 0x01的 AAI DREG-REQ 的响应, 以上描述对应步骤 S704。 或者, AMS可以设定一个计时器 (DREG Receive timer),计时器在 AMS 发送 AAI_DREG-REQ时启动, AMS在所述计时器过期之前(即, 到达基站 预先设置并通知终端的时间阈值之前) 收到的 AAI_DREG-CMD 就认为是 ABS 主动发起的 idle 启动命令, AMS 在所述计时器过期之后收到的 AAI DREG-CMD就认为是 ABS的响应, 以上描述对应上述步骤 S806。 方法实施例三 实施例六 本实施例提供了一种空闲模式控制方法, 图 9示出了根据本发明实施例 六的空闲模式控制方法的处理流程, 如图 9所示, 该方法包括以下步骤: 步骤 S902, 终端接收来自基站的去注册命令消息。 步骤 S904, 终端向基站发送通知消息, 其中, 通知消息的类型指示终端 对基站发送的去注册命令消息的类型的判断。 当终端认为去注册命令消息是 对终端发送的去注册请求消息的响应时, 该终端发送通知消息并进入空闲模 式, 该通知消息具体为确认消息以进行响应; 当终端认为去注册命令消息是 基站主动发起空闲模式的消息时, 该终端将忽略自己发送的请求, 发送通知 消息并进入空闲模式, 该通知消息具体为对该去注册命令消息的响应消息。 步骤 S906, 基站获取来自终端的通知消息, 其中, 通知消息用于通知基 站终端进入了空闲模式, 基站收到该通知消息将认为终端进入空闲。 下面以 802.16m系统为例, 结合具体实例对实施例六提供的方法进行举 例说明。 实例 8
AMS发送 0x01的 AAI DREG-REQ后, 收到 0x05的 AAI DREG-CMD 消息, 且该消息内没有携带 REQ-Duration参数。 如果 AMS认为是对自己发送的 AAI_DREG-REQ的响应消息, 则 AMS 发送 AAI_DREG-ACK消息给 ABS并进入 idle, 如果 ABS发送的确实是响 应消息, ABS在) 到 AAI DREG-ACK,且 MRHT到期后释放 AMS的资源, 如果 ABS是主动发起 idle,则当收到 AAI_DREG-ACK时, 认为 AMS已经进 入 idle, 即 jt匕时 AAI_DREG-ACK的作用等同于 0x02的 AAI_DREG-REQ。 这里, AMS 可以设定一个计时器 (timer) , 计时器在 AMS 发送 AAI DREG-REQ 时启动 , AMS 在所述计时器过期之前收到 的 AAI DREG-CMD就认为是 ABS主动发起的 idle启动命令, AMS在所述计 时器过期之后收到的 AAI_DREG-CMD就认为是 ABS的响应。 如果 AMS 认为是 ABS 主动发起 idle ,则 AMS 发送 0x02 的
AAI DREG-REQ 进行响应, 如果 ABS 发送的是响应, 则 ABS 收到 AAI DREG-REQ后, 可以确认 AMS进入了 idle,如果 ABS确实是主动发起 idle 欠到 AAI DREG-REQ后, 将认为 AMS进入 idle。 实例 9 无论是由 ABS启动或者 AMS启动的进入 IDLE模式过程, AMS收到
0x05的 AAI_DREG-CMD消息, 且该消息内没有携带 REQ-Duration参数, 如果同意进入 idle模式, 则一定要发送包括 0x02的 AAI_DREG-REQ。 这样 也可以解决背景技术中提到的问题。 装置实施例一 在本实施例中, 提供了一种基站, 图 10 示出了根据本发明装置实施例 一的基站的结构, 如图 10所示, 该基站包括: 配置模块 101 , 用于在去注册 命令消息中配置用于指示去注册命令消息的类型的控制信息, 其中, 去注册 命令消息的类型包括: 基站主动发起空闲模式的消息、 基站对终端的去注册 请求消息的响应消息; 发送模块 102 , 连接于配置模块 101 , 用于向终端发 送经配置模块 101配置后的去注册命令消息。 装置实施例二 在本实施例中,提供了一种终端, 图 11示出了 居本发明装置实施例二 的终端的结构, 如图 11所示, 该终端包括: 发射器 111、 接收器 112、 控制 器 113和定时器 114、 判决器 115 , 以下对该终端的各组成部分的功能及连接 关系进行详细的描述。 发射器 111 , 用于向基站发送去注册请求消息; 接收器 112 , 用于接收来 自基站的去注册命令消息; 控制器 113和定时器 114 , 控制器 113连接于发 射器 111 , 定时器 114连接于控制器 113 , 其中, 控制器 113在发射器 111发 送去注册请求消息的同时启动预先设置的定时器; 判决器 115 , 连接于定时 器 114和接收器 112 , 用于根据接收器 112接收到去注册命令消息的时刻确 定去注册命令消息的类型, 其中, 如果接收器 112在定时器 114超时前接收 到去注册命令消息,则确定去注册命令消息是基站主动发起空闲模式的消息; 否则, 确定去注册命令消息是对终端发送的去注册请求消息的响应。 装置实施例三 在本实施例中, 提供了一种终端, 图 12 示出了根据本发明装置实施例 三的终端的结构, 如图 12所示, 该终端包括: 接收模块 121 , 用于接收基站 发来的去注册命令消息; 发送模块 122 , 连接于接收模块 121 , 用于向基站 发送通知消息, 通知消息用于通知基站终端进入了空闲模式。 其中, 通知消息可以是确认消息, 也可以是响应消息, 如果终端判断其 接收模块 121 接收的去注册命令消息是对终端发送的去注册请求消息的响 应, 则通过发送模块 122发送确认消息, 并进入空闲模式; 如果终端判断其 接收模块 121接收的去注册命令消息是基站主动发起空闲模式的消息, 则通 过发送模块 122发送响应消息, 并进入空闲模式。 综上所述, 上述实施例中提供的空闲模式控制方法能够解决由于基站定 义不清晰带来的终端和基站的操作的混淆问题, 从而使终端和基站在空闲模 式发起时能够达到操作一致, 提高了空口传输的效率。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
