Description

系统信息的获取方法、 装置以及系统 技术领域
本发明涉及一种通信领域, 特别涉及一种系统信息的获取方法、 装置以及系统。 背景技术
随着无线通信的不断发展, 机器类型通信(MTC, Machine Type Communication) 应用变得越来越受欢迎。 主要包括物品追踪 /跟踪, 环境 /气候监测, 远程医疗等。 由 于 MTC的应用场景非常广泛, 目前针对 MTC的研究课题也随着增多, 例如有研究 如何节能的, 有研究如何降低成本的以及研究如何提高网络覆盖的等。但对于所有的 这些研究, 一个很重要的前提就是只能基于目前的 LTE 系统进行增强以实现这些课 题的研究目标。
随着对课题的不断研究, 这些课题都可能面临一个相同的问题, 即如何获取网络 广播的系统信息 (SI, System Information)。 系统信息是保证用户设备 (UE, User Equipment) (不管是处于空闲态还是连接态)正常工作所必不可少的信息。 系统信息 是由基站在某个特定小区进行广播, 所有处于这个小区的 UE都必须去获取必要的系 统信息。 只有当获取了这些必要的系统信息之后, UE才能执行小区选择 /重选, 小区 切换, 业务发起等过程。

具体实施方式
参照附图, 通过下面的说明书, 本发明的前述以及其它特征将变得明显。在说明 书和附图中, 具体公开了本发明的特定实施方式, 其表明了其中可以采用本发明的原 则的部分实施方式, 应了解的是, 本发明不限于所描述的实施方式, 相反, 本发明包 括落入所附权利要求的范围内的全部修改、 变型以及等同物。
在本发明实施例中, 以下以 MTC UE为例进行说明。 但值得注意的是, 本发明 实施例中的系统信息的获取方法以及修改周期的配置方法并不限于 MTC UE,只要存 在至少两种用户设备均可以适用于本发明实施例。
系统信息是在某个特定小区由基站进行广播,可以实现对空闲态和连接态的用户 设备的控制。由于随着时间的变化,网络会根据当前的网络状态对系统信息进行更新。 目前的 LTE系统采用修改周期 (MP, Modification Period) 的方法来实现系统信息的 更新。
图 1是现有标准中系统信息的更新示意图。 从图 1可以看出, 如果系统信息(例 如除了地震海啸预警系统( ETWS, Earthquake and Tsunami Warning System), 商业移 动警报业务 (CMAS, Commercial Mobile Alert Service) 以及扩展接入禁止 (EAB, Extended Access Barring)参数外)发生改变, 网络侧会在整个修改周期 n内发送更新 指示 (例如通过寻呼消息发送), 并在修改周期 n+1发送更新后的系统信息。 UE一旦收到网络侧的更新指示, 则需要在收到更新指示 (例如在修改周期 n) 的下一个修改周期 (例如修改周期 n+1 ) 的一开始就去获取新的系统信息。 修改周期 ΓΜΡ由两个参数决定, 分别是缺省寻呼周期 7。^ (default paging cycle)和修改周期系
¾ MP∞e ( modification period coefficient ) , 这两个参数由基站侧进行广播。 TMP― MPce * Tpaging ( 1 ) 如上式 a ) 所示, 通过寻呼周期值和修改周期系数值可以获得修改周期值。 此 夕卜, 修改周期的边界由满足一定条件的系统帧号(SFN, System Frame Number)值来 表示, 即 SFN mod m = 0。 其中 m为 ΓΜΡ所包含的无线帧数。 实施例 1
本发明实施例提供一种系统信息的获取方法,以下从基站侧对本发明实施例进行 说明。 图 2是本发明实施例的系统信息的获取方法的一流程图, 如图 2所示, 所述获 取方法包括:
步骤 201, 基站设置至少两个用于指示系统信息更新的指示符, 所述至少两个指 示符对应于至少两个用户设备;
步骤 202, 基站向用户设备发送指示符, 使得用户设备根据各自的修改周期来获 取系统信息。
在本实施例中, 基站侧针对同一小区的至少两个 UE可以分别设置用于指示系统 信息更新的指示符。 为方便描述, 以下以传统 UE和 MTC UE为例进行说明, 但本发 明不限于此。 例如还可以是其他类型的 UE, 或者还可以是三种或者三种以上的 UE, 可以使用三种或者三种以上的指示符来指示这些 UE, 可以根据实际情况确定具体的 实施方式。
在本实施例中, 该至少两个指示符可以分别包含在寻呼消息中。基站可以独立地 设置至少两个系统信息更新的指示符, 以达到分别通知至少两个 UE (传统 UE和新 的 MTC UE) 的目的。 其中, 至少两个 UE可以分别配置不同的修改周期; 例如可以 预先为至少两个 UE设置不同的修改周期, 也可以由基站侧对修改周期进行配置, 但 本发明不限于此。
例如, 传统 UE和新的 MTC UE可以分别配置不同的修改周期, 传统 UE可以配 置修改周期 PA, MTC UE可以配置修改周期 PB。 其中 PA可以小于 PB。 在本实施例中, 用户设备接收到基站发送的指示符之后, 可以根据各自的修改周 期分别进行系统信息的更新。
图 3是本发明实施例的系统信息的获取方法的一示例图。 如图 3所示, 传统 UE (UE A) 的修改周期为 PA, MTC UE (UE B) 的修改周期为 PB。 UE A在修改周期 n接收到指示符之后, 如果该指示符是针对该 UE A的指示符, 则 UE A在修改周期 n+1进行系统信息的更新。 如图 3所示, UE B在修改周期 m接收到指示符之后, 如 果该指示符是针对该 UE B的指示符,则 UE B在修改周期 m+1进行系统信息的更新。
由上述实施例可知, 通过基站分别独立地设置系统信息更新的指示符, 可以使得 MTC UE能及时获取最新的系统信息,又能保证不进行额外的不必要的系统信息获取 以降低 MTC UE的功率消耗。
图 4是本发明实施例的系统信息的获取方法的另一示意图。如图 4所示, 所述获 取方法包括:
步骤 401, 基站为至少两个用户设备分别配置修改周期。
步骤 402, 基站设置至少两个用于指示系统信息更新的指示符, 所述至少两个指 示符对应于至少两个用户设备;
步骤 403, 基站向用户设备发送指示符, 使得用户设备根据各自的修改周期来获 取系统信息。
在本实施例中, 新的修改周期值可以由基站决定, 可以通过在系统消息中进行广 播来实现; 或在专用信令中发送相关的参数来实现, 例如可以使用无线资源控制 ( RRC, Radio Resource Control)信令或媒体接入控制( MAC, Medium Access Control) 信令。
在步骤 401中, 对于其中一个用户设备(传统 UE), 可以采用现有标准的修改周 期值; 对于另一个用户设备 (MTC UE), 可以进行如下处理:
在一个实施方式中, 可以向该用户设备发送修改周期值。 例如, 基站可以直接产 生一个新的修改周期值, 并将该修改周期值发送给该用户设备。
或者, 在另一个实施方式中, 可以向该用户设备发送寻呼周期值, 使得该用户设 备根据寻呼周期值以及已有的修改周期系数获得修改周期值。例如, 基站只产生一个 新的缺省寻呼周期 7:。 并重用已有的修改周期系数, 相应的修改周期值 7^可以表示 为 TM >― MP∞e * Tpaging
或者,在另一个实施方式中,可以向该用户设备发送寻呼周期值和修改周期系数, 使得该用户设备根据寻呼周期值以及修改周期系数获得修改周期值。例如, 基站产生 一个新的缺省寻呼周期 7;^和一个新的修改周期系数 MP:,相应的修改周期值 ?ς可 以表示为 4 = MP: * 7 ^。
此外, 新的修改周期边界可以采用现有的方法确定, 即 SFN mod m* = 0, 其中 m*为 7^所包含的无线帧数。
在步骤 401中为至少两个用户设备分别配置修改周期后,可以执行步骤 402和步 骤 403进行系统信息的获取, 具体内容可以参考上述的步骤 201和步骤 202。
在本实施例中, 系统信息可以部分被更新, 也可以全部被更新。 部分系统信息对 于同一小区的不同 UE, 可能可以独立地进行更新, 也可能需要同步进行更新。
在一个实施方式中, 步骤 403中向用户设备发送指示符具体还可以包括: 对于两 个或两个以上的用户设备, 可以在不同的时刻发送指示符, 使得两个或两个以上的用 户设备根据各自的修改周期同时更新系统信息的部分或者全部。
可以先对系统信息进行一个简单的分类: 例如,将需要被传统 UE和 MTC UE同 时更新的系统信息称为 A 类系统信息; 例如主信息块 (MIB, Master Information Block),系统信息块 1 ( SIB1 , System Information Block 1 )中的时分双工(TDD, Time Division Duplex) 配置和频带指示符, 系统信息块 2 ( SIB2) 中的频率信息等。 可以 将除了包含在 A类系统信息中的其它系统信息称为 B类系统信息。
基于上述描述, 新的系统信息更新机制可以描述为: 定义两个系统信息改变指示 符: 一个用于传统 UE而另一个用于新 UE。 对于 B类的系统信息发生改变, 基站可 以独立的设置两个系统信息更新的指示符,以达到分别通知传统 UE和新 UE的目的。 而对于 A类的系统信息发生改变,基站需要保证传统 UE和新 UE在同一时刻进行系 统信息的更新。
图 5是本发明实施例的系统信息的获取方法的另一示例图。 如图 5所示, 传统
UE (UE A) 的修改周期为 PA, MTC UE (UE B) 的修改周期为 PB。 为了使传统 UE 和 MTC UE同步地获得 A类消息, 可以在修改周期 n+8发送针对 UE A的指示符, 在修改周期 m+1发送针对 UE B的指示符, 从而 UE A和 UE B在同一时刻 (修改周 期 n+9和修改周期 m+2的开始) 进行系统信息的更新。 在本实施例中, 所述方法还可以包括: 通过专用信令将系统信息的部分或者全部 发送给用户设备。
例如, 引入新的修改周期后, 当使用新的修改周期的 UE想要发起上行业务时, 并没有获得新的系统信息, 有可能会影响目前网络其它 UE的通信。 因此, 可以将某 些系统信息通过专用信令的方式发送给 UE, 例如承载在信令无线承载 1 ( SRB1, Signaling Radio Beare) 禾 B S B2的 RRC信令。
值得注意的是,通过专用信令将系统信息的部分或者全部发送给用户设备的方法 并不限于使用至少两个指示符的情况, 或者并不限于使用至少两个修改周期的情况, 在使用一个指示符或者一个修改周期的情况下也可以适用。
由上述实施例可知,通过基站分别独立地为用户设备设置用于系统信息更新的指 示符, 可以使得例如 MTC UE能及时获取最新的系统信息, 又能保证不进行额外的 不必要的系统信息获取以降低 MTC UE的功率消耗。 实施例 2
本发明实施例提供一种系统信息的获取方法, 从用户设备侧进行说明, 与实施例
1相同的内容不再赘述。图 6是本发明实施例的系统信息的获取方法的一流程示意图, 如图 6所示, 所述获取方法包括:
步骤 601, 用户设备接收用于指示系统信息更新的指示符;
步骤 602, 用户设备确定该指示符对应于该用户设备;
步骤 603, 用户设备根据该用户设备的修改周期来获取系统信息。
在本实施例中,基站可以为至少两个用户设备分别设置用于系统信息更新的指示 符。 在一个用户设备(例如 MTC UE)接收到基站侧发送的指示符之后, 确定该指示 符是否是针对该用户设备, 即是否对应于该用户设备的用于系统信息更新的修改周 期。在确定对应于该用户设备的用于系统信息更新的修改周期的情况下, 该用户设备 根据自身的修改周期来获取系统信息。
图 7是本发明实施例的系统信息的获取方法的另一流程示意图, 如图 7所示, 所 述获取方法包括:
步骤 701, 用户设备接收基站发送的修改周期的配置信息, 其中基站为至少两个 用户设备分别配置修改周期; 步骤 702, 用户设备根据配置信息获得用于系统信息更新的修改周期。
其中, 修改周期的配置信息可以包括: 修改周期值; 用户设备可以直接获得该修 改周期值。 或者, 修改周期的配置信息可以包括: 寻呼周期值; 用户设备可以根据该 寻呼周期值以及已有的修改周期系数获得修改周期值。或者, 修改周期的配置信息可 以包括: 寻呼周期值和修改周期系数; 用户设备可以根据该寻呼周期值以及该修改周 期系数获得修改周期值。
步骤 703, 用户设备接收用于指示系统信息更新的指示符;
步骤 704, 用户设备判断该指示符是否针对该用户设备; 在确定针对该用户设备 的情况下执行步骤 705 ;
步骤 705, 用户设备根据该用户设备的修改周期来获取系统信息。
由上述实施例可知,通过基站分别独立地为用户设备设置用于系统信息更新的指 示符, 可以使得例如 MTC UE能及时获取最新的系统信息, 又能保证不进行额外的 不必要的系统信息获取以降低 MTC UE的功率消耗。 实施例 3
