图 5是本发明一个实施例的基站的框图。
图 6是本发明另一实施例的用户设备的框图。 具体实施方式 下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进 行清楚、 完整地描述， 显然， 所描述的实施例是本发明一部分实施例， 而 不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有 作出创造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范 围。
本发明的技术方案， 可以应用于各种通信系统， 例如： 全球移动通信 系统（ GSM, Global System of Mobile communication ), 码分多址（ CDMA, Code Division Multiple Access ) 系统， 宽带码分多址（ WCDMA, Wideband Code Division Multiple Access Wireless ),通用分组无线业务（ GPRS, General Packet Radio Service ), 长期演进 ( LTE, Long Term Evolution )等。
用户设备 （ UE , User Equipment ) , 也可称之为移动终端 （ Mobile Terminal ),移动用户设备等，可以经无线接入网（例如， RAN, Radio Access Network )与一个或多个核心网进行通信， 用户设备可以是移动终端， 如移 动电话 （或称为 "蜂窝" 电话）和具有移动终端的计算机， 例如， 可以是 便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置， 它们与无 线接入网交换语言和 /或数据。
基站，可以是 GSM或 CDMA中的基站（ BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站（ NodeB ),还可以是 LTE中的演进型基站（ eNB 或 e-NodeB , evolutional Node B ), 本发明并不限定， 但为描述方便， 下述 实施例以 eNB为例进行说明。
图 1是本发明一个实施例的信息传输方法的流程图。 图 1的方法由基 站执行。
101 , 在地震海嘯告警系统 ETWS消息广播结束之后， 生成寻呼消息。
102, 向处于监听 ETWS消息状态的 UE发送寻呼消息， 寻呼消息用于 指示 UE接收系统消息块， 系统消息块不携带 ETWS主要通知消息 PN和 ETWS次要通知消息 SN调度映射信息。
本发明实施例通过 UE接收基站广播的寻呼消息， 主动接收不携带 ETWS主要通知消息 PN和 ETWS次要通知消息 SN调度映射信息的系统消 息块， 使得 UE能够停止监听 ETWS消息， 有效地降低 UE的耗电量。
可选地， 作为一个实施例， 寻呼消息可以为携带系统消息更新指示消 息的寻呼消息。 应理解， 本发明实施例对此并不限定。 当 UE没有离开服务 小区时， 可以触发 UE主动接收不携带 ETWS PN和 ETWS SN调度映射信 息的系统消息块的寻呼消息均落入本发明实施例的范围内。
可选地，作为另一个实施例，上述系统消息块的系统消息值标记 System Info Value tag字段可以在基站发送寻呼消息之前和基站发送寻呼消息之后 均保持一致。 进一步地， 上述系统消息块可以为不携带 ETWS PN和 ETWS SN调度映射信息的 SIB1。
具体而言， 基站在 ETWS消息广播结束后， 广播携带系统消息更新指 示消息的寻呼消息。 UE接收该寻呼消息后， 主动接收 SIB1 , 其中 SIB1不 携带 ETWS PN和 ETWS SN调度映射信息，并且 SIB1的 System Info Value tag字段保持不变。 因此， UE接收到携带系统消息更新指示消息的寻呼消 息后并没有对系统消息进行更新。 这样， UE停止监听 ETWS消息， 不处于 耗电状态， 从而节省功耗。
下面还将结合图 3 的例子详细描述信息传输方法的非限制性的实施方 式。 图 2是本发明一个实施例的信息传输方法的流程图。 图 2的方法由用 户设备执行， 并与图 1的方法相对应， 因此将适当省略与图 1的实施例重 复的描述。
201 , 当处于监听 ETWS消息状态时， 接收基站广播的寻呼消息。
202, 根据寻呼消息接收系统消息块， 系统消息块不携带 ETWS主要通 知消息 PN和 ETWS次要通知消息 SN调度映射信息。
203 , 根据系统消息块停止监听 ETWS消息。
本发明实施例通过 UE接收基站广播的寻呼消息， 主动接收不携带 ETWS主要通知消息 PN和 ETWS次要通知消息 SN调度映射信息的系统消 息块， 使得 UE能够停止监听 ETWS消息， 能够有效地降低 UE的耗电量。
可选地， 作为一个实施例， 寻呼消息可以为携带系统消息更新指示消 息的寻呼消息。 应理解， 本发明实施例对此并不限定。 当 UE没有离开服务 小区时， 可以触发 UE主动接收不携带 ETWS PN和 ETWS SN调度映射信 息的系统消息块的寻呼消息均落入本发明实施例的范围内。
可选地，作为另一个实施例，上述系统消息块的系统消息值标记 System Info Value tag字段可以在基站发送寻呼消息之前和基站发送寻呼消息之后 均保持一致。 进一步地， 上述系统消息块可以为不携带 ETWS PN和 ETWS SN调度映射信息的 SIB1。
具体地， 基站 ETWS消息广播结束， 但 UE还处于监听 ETWS消息状 态。 例如， UE下行接收信号突然变弱， 以致于无法完整接收 ETWS消息， 此时 UE 就会一直处于监听 ETWS 消息的状态， 而不会主动接收不携带 ETWS PN和 ETWS SN调度映射信息的 SIB1。 当 UE接收到基站主动下发 的寻呼消息 （例如， 携带系统消息更新指示消息的寻呼消息）后， 主动接 收系统消息块，该系统消息块不携带 ETWS PN和 ETWS SN调度映射信息。 进一步地， 该系统消息块可以是不携带 ETWS PN和 ETWS SN调度映射信 息的 SIB1。 因此， UE接收到携带系统消息更新指示消息的寻呼消息后并没 有对系统消息进行更新。这样， UE停止监听 ETWS消息，不处于耗电状态， 从而节省功耗。
下面结合具体的例子详细描述本发明实施例。
图 3是本发明一个实施例的信息传输方法的过程的示意性流程图。 在图 3中， 基站以 eNB为例进行说明。 应理解， 本发明实施例对此并 不作限定。应注意的是，图 3的 ETWS SN分片的数目为 2仅仅是示例性的， 而非对本发明实施例的限制， ETWS SN分片的数目还可以不分片或者是多 片。 还应理解， 本发明实施例对 ETWS PN或者 ETWS SN被广播的次数和 时间间隔不作限定。
301 , MME 向基站发送警报广播请求消息 Write-Replace Warning Request。
302 , 基站回复 MME 警报广播响应消息 Write-Replace Warning Response。
303 , 基站向 UE广播 ETWS消息。
广播内容包括 ETWS PN和 ETWS SN。 ETWS PN用于快速向用户通告 即将发生事件的最为紧急的信息（例如，即将发生的地震或海嘯 )。 ETWS SN 主要用于传送附加信息 （例如， 发生紧急事件时， 应该怎么做或到哪里获 得帮助等）。 一般情况， ETWS PN不需要分片， 并按照一定的时间间隔连 续广播。 而 ETWS SN的量较大时， 则需要分片广播。 例如， ETWS SN被 分成两片， 分别为 SN-分片 -1和 SN-分片 -2。 ETWS SN会按照 MME配置 的广播次数和广播时间间隔进行广播。 例如， ETWS SN被配置广播 2次， 广播时间间隔为 10秒。
UE接收到基站发送的携带 ETWS 消息指示的寻呼消息 paging(with etws-ind), 相应的就会接收 SIB1 (映射信息 SIB10 SIB11 ) , 根据 SIB1提供 的相关信息在固定的时频位置去监听携带 ETWS PN的 SIB10 ( PN )和携带 ETWS SN的 SIB11 ( SN )。 基站 ETWS消息广播结束，但 UE还处于监听 ETWS消息状态。 例如， UE下行接收信号突然变弱， 以致于无法完整接收 ETWS消息， 而 UE不会 主动接收不携带 ETWS PN和 ETWS SN调度映射信息的 SIB 1。 又例如， UE开机时正好是 eNB最后一次广播 ETWS SN, UE没能完整地接收 ETWS SN, 而不会主动接收不携带 ETWS PN和 ETWS SN调度映射信息的 SIB1。 因此， UE就会一直处于监听 SIB11的状态， 即 UE—直处于耗电状态。
304, 基站向 UE发送携带系统消息更新指示消息的寻呼消息。
305, 基站向 UE发送不携带 ETWS PN和 ETWS SN调度映射信息的 SIB1。
当 UE接收到基站主动下发的寻呼消息（例如，携带系统消息更新指示 消息的寻呼消息 )后， 主动接收不携带 ETWS PN和 ETWS SN调度映射信 息的系统消息块。 可选地， 该系统消息块的系统消息值标记 System Info Value tag字段可以在基站发送寻呼消息之前和基站发送寻呼消息之后均保 持一致。 进一步地， 该系统消息块可以是不携带 ETWS PN和 ETWS SN调 度映射信息的 SIB1 , 即该系统消息块是基站广播结束时向 UE发送的被移 除 SIB10和 SIB11调度映射信息的 SIB1 ,并且 SIB1的 System Info Value tag 字段保持不变。 因此， UE接收到携带系统消息更新指示消息的寻呼消息后 并没有对系统消息进行更新。 这样， UE停止监听 ETWS消息， 从而节省功 耗。 实施例。 本发明实施例可应用于各种通信系统中的基站或用户设备。 图 4 示出了一种设备的实施例， 在该实施例中，设备 400包括发射电路 402、 接 收电路 403、 功率控制器 406、 解码处理器 405、 处理器 406, 存储器 407 及天线 401。 处理器 406控制设备 400的操作， 处理器 406还可以称为中 央处理器 CPU或者处理器。 存储器 407可以包括只读存储器和随机存取存 储器， 并向处理器 406提供指令和数据。 存储器 407的一部分还可以包括 非易失行随机存取存储器（NVRAM )。 具体的应用中， 设备 400可以嵌入 或者本身可以就是例如移动电话之类的无线通信设备， 还可以包括容纳发 射电路 402和接收电路 403的载体， 以允许设备 400和远程位置之间进行 数据发射和接收 。发射电路 402和接收电路 403可以耦合到天线 401。设 备 400的各个组件通过总线系统 410耦合在一起，其中 总线系统 410除 包 括数据总线之外， 还包括电源总线、 控制总线和状态信号总线。 但是为了 清楚说明起见， 在图中将各种总线都标为总线系统 410。设备 400还可以包 括用于处理信号的处理器 406、 此外还包括功率控制器 404、 解码处理器 405。 .

发送单元 52用于广播处理器 51生成的寻呼消息， 寻呼消息用于指示 处于监听 ETWS消息状态的用户设备 UE接收系统消息块， 系统消息块不 携带 ETWS主要通知消息 PN和 ETWS次要通知消息 SN调度映射信息。
本发明实施例通过 UE接收基站广播的寻呼消息， 主动接收不携带 ETWS主要通知消息 PN和 ETWS次要通知消息 SN调度映射信息的系统消 息块， 使得 UE能够停止监听 ETWS消息， 有效地降低 UE的耗电量。
