技术领域
本公开涉及通信技术领域,特别的指一种系统信息的更新方法、基站及终端。
背景技术
LTE系统的系统信息(SI,System Information)主要分为MIB(Master Information Block,主信息块)和多个SIBs(System Information Blocks,系统信息块)。终端UE新接入一个小区或广播消息发生改变时,都会获取系统信息(MIB/SIB)。系统信息包括:MIB、SIB1和SI,其中SI包含SIB2~SIB22,还可能继续扩展。
以下列举几个系统信息的内容和传输特点。
MIB:用于系统接入。MIB上传输几个比较重要的系统信息参数,如小区下行带宽、PHICH(Physical Hybrid ARQ Indicator Channel,物理混合自动重传指示信道)配置参数、无线系统帧号SFN,在物理广播信道PBCH上发送,传输周期为40ms,也就是从系统帧号mod 4等于0的无线帧开始,传输4次。时域资源上,承载MIB的传输块在每10ms无线帧的子帧0第二个时隙的前4个OFDM符号上传输。频域资源上,占据频带中间的1.08MHz(72个子载波,包括了保护频带)。
SIB1:广播小区接入与小区选择的相关参数以及SI消息的调度信息(包含了一个或多个SIB2~13)。SIB1周期80ms,初始传输在SFN mod 8=0无线帧的子帧5,在80ms周期内SFN mod 2=0的无线帧的子帧5重复传输。
其他系统信息SI需要在SIB1中进行调度。
SIB2:小区内所有UE共用的无线参数配置,其它无线参数基本配置。
SIB3:小区重选信息,主要关于服务小区重选参数以及同频小区重选参数。
SIB4:同频邻区列表以及每个邻区的重选参数、同频白/黑名单小区列表。
SIB5:异频相邻频点列表以及每个频点的重选参数、异频相邻小区列表以及每个邻区的重选参数、异频黑名单小区列表。
SIB6:UTRAFDD邻频频点列表以及每个频点的重选参数、UTRA TDD邻频频点列表以及每个频点的重选参数。
SIB7:GERAN邻频频点列表以及每个频点的重选参数。
SIB8:CDMA2000的预注册信息、CDMA2000邻频频段列表和每个频段的重选参数、CDMA2000邻频频段的邻区列表。
SIB9:Home eNodeB的名称。
SIB10:ETWS主通知(primary notification)。
SIB11:ETWS辅通知(secondary notification)。
SIB12:CMAS通知(CMAS notification)。
SIB13:获取跟一个或多个MBSFN区域相关的MBMS控制信息的信息。
SIB14~SIB22各有其针对的特性,不再一一描述。
相关技术的LTE系统中,在第n个修改周期内,基站在寻呼(paging)消息中发送1比特“系统信息变更指示”(systemInfoModification),通知终端有系统信息将要变更。在第n+1个修改周期到达后,UE重新读取所有的系统信息,包括MIB,SIB1,SIB2等等。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,本公开一些实施例提供一种系统信息的更新方法,包括:
步骤11,向终端发送系统信息的变更指示;所述变更指示用于指示所述系统信息包含的多个系统信息块组是否发生变更;每个所述系统信息块组包含至少一个系统信息块;
步骤12,向所述终端发送变更后的系统信息。
本公开一些实施例提供的系统信息的更新方法应用于网络侧的基站,该基站可以是宏站,如LTE eNB、5G NR NB(gNB)等;也可以是小站,如低功率节点(LPN,low power node)、微基站(pico)、家庭基站(femto)等, 接入点(AP,access point);也可以是中央单元(CU,central unit)与其管理和控制的多个传输接收点(TRP,Transmission Reception Point)共同组成的网络节点。一个基站下有一个或多个小区(不同的频点或扇区分裂)。
当基站需要变更系统信息时,首先需要向终端发送系统信息的变更指示,通过该变更指示对系统信息包含的多个系统信息块组是否发生变更进行分别指示。例如系统信息被划分为系统信息块组A和系统信息块组B,变更指示信息包括2比特,01则表示系统信息块祖A发生变更,系统信息块组B未发生变更。终端可准确的进行发生变更的系统信息块组A的获取。
进一步的,该系统信息的变更指示可以在寻呼(paging)消息中发送,也可以在直接指示信息(Direct Indication Information)中发送;直接指示信息,就是用1bit直接指示哪个系统信息块组变更了,UE收到后的行为和收到寻呼消息后的行为类似,但是直接指示信息是在5G物理下行控制信道(NR-PDCCH)上传输,而寻呼消息是在寻呼控制信道(PCCH)上传输。
该系统信息的变更指示还可以在其他消息中发送,比如唤醒waking up消息,功率节省power saving消息,在此不作详细描述。
需要说明的是,本公开的上述实施例中提及的系统信息块具体包括:LTE(长期演进)系统中规定的主信息块MIB和多个系统信息块SIBs(例如SIB1-SIB22,还有可能继续扩展,在此不对SIB的数量进行限定)。
可选的,本公开的上述实施例中步骤11之前,所述方法还包括:
对所述系统信息包含的多个系统信息块进行分组,确定多个系统信息块组。
本公开一些实施例中提供三种对系统信息进行分组的方式,具体的,方式一:根据所述系统信息块的内容进行分组,确定多个系统信息块组;或者,
方式二:根据所述系统信息块的传输方式进行分组,确定多个系统信息块组;或者,
方式三:根据所述系统信息块的更新时机进行分组,确定多个系统信息块组。
方式一具体为:
根据所述系统信息块的内容,确定第一系统信息块组和第二系统信息块 组;其中,所述第一系统信息块组包括主信息块MIB,所述第一系统信息块组还包括:系统信息块SIB1和/或系统信息块SIB2;所述第二系统信息块组包括:所述系统信息中除所述第一系统信息块组之外的其他系统信息块。
该第一系统信息块组也可以称为最小系统信息(MSI,minimum system information),通常情况下该最小系统信息是周期广播的系统信息。该第二系统信息块组也可以称为其他系统信息(OSI,other system information),该OSI可以是周期广播的,也可以是按需广播的。具体的,SIB1中包含OSI(即第二系统信息块组)的调度信息(scheduling information)和有效信息(validity information);其中,有效信息包括:区域标识(areaID)和版本号(valuetag)。
可选的,系统信息的变更指示中系统信息被划分成第一系统信息块组和第二系统信息块组进行分别指示,例如,用2比特指示,01表示MSI没有变更,OSI变更;10表示MSI变更,OSI没有变更;11表示MSI变更,OSI变更。
进一步的,所述方法还包括:
将所述第一系统信息块组划分为第三系统信息块组和第四系统信息块组;
其中,所述第三系统信息块组包括主信息块MIB;所述第四系统信息块组包括系统信息块SIB1和/或系统信息块SIB2。
可选的,系统信息中第一系统信息块组被划分为两组,若第二系统信息块组未被再次划分,则系统信息的变更指示中系统信息被划分成第三系统信息块组、第四系统信息块组和第二系统信息块组进行分别指示,例如,用3比特指示,001表示MIB没有变更,SIB和/或SIB2没有变更,OSI变更。
进一步的,所述方法还包括:
将所述第二系统信息块组划分为第五系统信息块组和第六系统信息块组;其中,所述第五系统信息块组包括所述第二系统信息块组中周期广播的系统信息块;所述第六系统信息块组包括所述第二系统信息块组中按需广播的系统信息块;或者,
将所述第二系统信息块组划分为多个系统信息块组;其中,每个系统信息块组包含的系统信息块的功能相同。例如,SIB3~SIB5是小区重选参数, 分为一个系统信息块组进行指示;SIB6~SIB8是inter-RAT重选,分为一个系统信息块组进行指示;SIB10~SIB12是PWS通知,分为一个系统信息块组进行指示。
可选的,系统信息中第一系统信息块组被划分为两组,若第二系统信息块需也被划分为两组,则系统信息的变更指示中系统信息被划分成第三系统信息块组、第四系统信息块组、第五系统信息块组和第六系统信息块进行分别指示,例如,用4比特指示,0001表示MIB没有变更,SIB和/或SIB2没有变更,OSI中周期广播的系统信息块没有变更,OSI中按需广播的系统信息块发生变更。
其中,针对第二系统信息块组被划分成多组的情况不再一一举例说明。
或者,方式一具体为:
根据所述系统信息块的内容,将所述系统信息包含的每个系统信息块划分成一个系统信息块组;所述系统信息块包括:主信息块MIB和多个系统信息块SIB;例如,用SIB bitmap指示,{000110000000000000000}表示SIB3、SIB4变更,MIB、SIB1等其他的SIB没有变更。
或者,根据所述系统信息块的内容,将所述系统信息包含的每个系统信息消息(SI message)划分成一个系统信息块组;其中,每个系统信息消息包含一个或多个系统信息块;同一个系统信息消息中的系统信息块具有相同的系统信息周期和/或相同的系统信息窗口。SI message包含一个或一组SIB,SI message中的SIB具有相同的系统信息周期SI-period和/或相同的系统信息窗口SI-window。例如用SI message bitmap指示,{0001}表示SI message4变更,SI message1~3没有变更。
方式二具体为:
根据所述系统信息块的传输方式,确定第七系统信息块组和第八系统信息块组;
其中,所述第七系统信息块组包括所述系统信息中周期广播的系统信息块;所述第八系统信息块组包括所述系统信息中按需广播的系统信息块。
可选的,第七系统信息块可以称为周期广播的系统信息(periodically broadcast SI),第八系统信息块可以称为按需的系统信息(on-demand SI)。 系统信息的变更指示中系统信息被划分成第七系统信息块组和第八系统信息块组进行分别指示,例如,用2比特指示,01表示周期广播的系统信息没有变更,按需的系统信息变更;10表示周期广播的系统信息变更,按需的系统信息没有变更;11表示周期广播的系统信息变更,按需的系统信息变更。
方式三具体为:
根据所述系统信息块的更新时机,确定第九系统信息块组和第十系统信息块组;
其中,所述第九系统信息块组包括所述系统信息中需立即更新的系统信息块;所述第十系统信息块组包括所述系统信息中需下一修改周期更新的系统信息块。
可选的,需立即更新的系统信息块包括:公众预警系统PWS(Public Warning System)。公众预警系统PWS包括:商业移动预警服务CMAS(Commercial Mobile Alert Service)、地震和海啸预警系统ETWS(Earthquake and Tsunami Warning System)。
需要说明的是,本公开一些实施例中基站还可以对第十系统信息块组包含的系统信息块分别分组,可以基于系统信息块的功能或内容进行分组、也可以基于传输方式进行分组,在此不作具体限定。
综上,本公开的上述实施例中将系统信息划分为多个系统信息块组,并在系统信息的变更指示中对多个系统信息块是否发生变更进行分别指示,终端则能够基于接收到的变更指示确定发生变更的系统信息块,仅读取发生变更的系统信息块,从而减少不必要的系统信息的获取,节省终端的功率。
如图2所示,本公开一些实施例还提供一种系统信息的更新方法,包括:
步骤21,接收网络侧发送的系统信息的变更指示;所述变更指示用于指示所述系统信息包含的多个系统信息块组是否发生变更;所述系统信息块组包含至少一个系统信息块;
步骤22,根据所述变更指示更新所述系统信息。
当基站需要变更系统信息时,首先需要向终端发送系统信息的变更指示,通过该变更指示对系统信息包含的多个系统信息块组是否发生变更进行分别指示。例如系统信息被划分为系统信息块组A和系统信息块组B,变更指示 信息包括2比特,01则表示系统信息块组A发生变更,系统信息块组B未发生变更。终端可准确的进行发生变更的系统信息块组A的获取。
进一步的,该系统信息的变更指示可以在寻呼(paging)消息中发送,也可以在直接指示信息(Direct Indication Information)中发送;直接指示信息,就是用1bit直接指示哪个系统信息块组变更了,UE收到后的行为和收到寻呼消息后的行为类似,但是直接指示信息是在5G物理下行控制信道(NR-PDCCH)上传输,而寻呼消息是在寻呼控制信道(PCCH)上传输。
该系统信息的变更指示还可以在其他消息中发送,比如唤醒waking up消息,功率节省power saving消息,在此不作详细描述。
需要说明的是,本公开的上述实施例中提及的系统信息块具体包括:LTE(长期演进)系统中规定的主信息块MIB和多个系统信息块SIBs(例如SIB1-SIB22,还有可能继续扩展,在此不对SIB的数量进行限定)。
可选的,上述实施例中步骤22包括:
根据所述变更指示,确定发生变更的一个或多个系统信息块组;
获取发生变更的所述一个或多个系统信息块组。
本公开一些实施例中,终端根据变更指示能够准确的知道那个系统信息块组会变更,从而可以获取发生变更的系统信息块组的信息,减少不必要的系统信息的读取,节省终端的功率。
进一步的,本公开的上述实施例中,若发生变更的系统信息块组包括所述系统信息中需立即更新的系统信息块,所述获取发生变更的所述一个或多个系统信息块组的步骤,包括:
接收到所述变更指示后,立即获取最小系统信息MSI;所述最小系统信息MSI包括主信息块MIB,所述最小系统信息MSI还包括:系统信息块SIB1和/或系统信息块SIB2;
根据所述系统信息块SIB1,获取发生变更的系统信息块组的调度信息;
根据所述调度信息,获取发生变更的系统信息块组。
例如,终端在第n个修改周期内,收到系统信息的变更指示,该变更指示中指示需立即更新的系统信息块发生变更,则终端立即获取MSI,通过SIB1获取变更的系统信息块的调度信息,然后获取变更的系统信息。
例如,终端在变更指示中收到ETWS指示(ETWS indication),立刻读取MSI,通过SIB1获取ETWS的调度信息(例如,SIB10或SIB11的调度信息),然后获取ETWS(例如,SIB10或SIB11)。再例如,终端在变更指示中收到CMAS指示(CMAS indication),立刻读取MSI,通过SIB1获取CMAS的调度信息(例如,SIB12的调度信息),然后获取CMAS(例如,SIB12)。
进一步的,本公开的上述实施例中,若发生变更的信息块组包括所述系统信息中需下一修改周期更新的系统信息块,所述获取发生变更的所述一个或多个系统信息块组的步骤,包括:
接收到所述系统信息变更指示,在下一个修改周期到达后获取最小系统信息MSI;所述最小系统信息MSI包括主信息块MIB,所述最小系统信息MSI还包括:系统信息块SIB1和/或系统信息块SIB2;
根据所述系统信息块SIB1,获取发生变更的系统信息块组的调度信息;
根据所述调度信息,获取发生变更的系统信息块组。
例如,在第n个修改周期内,终端在寻呼消息中收到系统信息的变更指示,确定哪个系统信息块组会发生变更;在第n+1个修改周期到达后,终端获取变更的系统信息。如果MSI发生变更,那么第n+1个修改周期到达后,所有终端都需要读取MSI。
关于SIB1的是否变更,具体的:OSI中的SIB的调度信息发生变化,则SIB1发生变更;OSI中的SIB的有效信息(区域标识和版本号)发生变化时SIB1可能发生变更,也可能不发生变更。
需要说明的是,SIB1中包含的其他参数发生变化,SIB1也可能发生变更。例如,小区选择参数,接入相关参数(随机接入RACH,接入控制cellBarred/ACB等),无线资源配置参数,寻呼参数,跟踪区域tracking area/RAN area更新参数等。
进一步的,本公开的上述实施例中获取发生变更的所述一个或多个系统信息块组的步骤,包括:
若发生变更的所述一个或多个系统信息块组是终端感兴趣的系统信息,获取发生变更的系统信息块组;
若发生变更的所述一个或多个系统信息块组不是终端感兴趣的系统信息, 不获取发生变更的系统信息块组。
进一步的,所述若发生变更的所述一个或多个系统信息块组是终端感兴趣的系统信息,获取发生变更的系统信息块组的步骤,包括:
若发生变更的所述一个或多个系统信息块组是终端感兴趣的系统信息,获取最小系统信息MSI;所述最小系统信息MSI包括主信息块MIB,所述最小系统信息MSI还包括:系统信息块SIB1和/或系统信息块SIB2;
若所述系统信息块SIB1包含的其他系统信息OSI的调度信息发生变更,根据变更后的调度信息,获取发生变更的系统信息块组;若所述系统信息块SIB1包含的其他系统信息OSI的有效信息发生变更,根据所述系统信息SIB1包含调度信息获取发生变更的系统信息块组。
可选的,所述若所述系统信息块SIB1包含的其他系统信息OSI的有效信息发生变更,根据所述系统信息块SIB1包含调度信息获取发生变更的系统信息块组的步骤,包括:
根据所述系统信息块SIB1,获取发生变更的系统信息块组的有效信息;
若发生变更的系统信息块组的有效信息与终端本地存储的所述系统信息块组的有效信息不同,确定所述系统信息块SIB1包含的其他系统信息OSI的有效信息发生变更;
根据所述系统信息块SIB1包含的调度信息获取发生变更的系统信息块组。
可选的,如果有终端感兴趣的OSI中的某个系统信息组(例如,小区重选参数组SIB3~SIB5)发生变更,那么第n+1个修改周期到达时,终端先读取MSI,通过SIB1检查该组中SIB的有效信息(areaID+valuetag),从而确定哪些SIB与自己存储的区域号和/或版本号不同,然后读取变更SIB;区域号和版本号与UE已经存储的相同,则不需要再读取。如果没有终端感兴趣的OSI中的某组系统信息发生变更,那么终端不操作,可以休眠,节省功率。此时,OSI中SIB的有效信息(areaID、valuetag)即使发生变更,不影响SIB1,SIB1不变更;否则SIB1变更,所有终端都要读取MIB和SIB1,终端不能休眠。
进一步的,对于OSI中的按需的系统信息(on-demand SI),第n+1个修 改周期到达时,网络侧广播变更的on-demand SI,终端不需要发送on-demand SI请求,UE监听感兴趣的on-demand SI窗口,接收变更的on-demand SI。
或者,如果有终端感兴趣的OSI中的SIB或者SI message发生变更,那么第n+1个修改周期到达时,UE先读MSI,通过SIB1检查相应SIB或者SI message的有效信息(areaID、valuetag),从而确定哪些SIB或者SI message与自己存储的区域号和/或版本号不同,然后读取变更的SIB或者SI message;区域号和版本号与UE已经存储的相同,则不需要再读取。如果没有UE感兴趣的OSI中的SIB或者SI message发生变更,那么UE不操作,可以休眠,节省功率。此时,OSI中SIB的有效信息(areaID+valuetag)发生变化,不影响SIB1,SIB1不变更;否则SIB1变更,所有终端都要读取MIB和SIB1,终端不能休眠。
为了更详细的描述本申请提供的系统信息的更新方法,下面结合具体的示例对系统信息的更新方法进行阐述:
示例一:终端进行PWS系统信息变更指示(PWS SI change indication)的过程。
第n个修改周期内,UE1在寻呼消息中收到ETWS的变更指示。UE1立刻读取MSI,通过SIB1获取SIB10的调度信息,然后获取SIB10,其中,SIB10中包含ETWS主通知。同理,UE1立刻读取MSI,通过SIB1获取SIB11的调度信息,然后获取SIB11,其中,SIB11中包含ETWS辅通知。
同理,UE1在寻呼消息中收到CMAS的变更指示。UE1立刻读取MSI,通过SIB1获取SIB12的调度信息,然后获取SIB12,其中,SIB12包含CMAS通知。
示例二:终端进行按需的系统信息变更指示(on-demand SI change indication)的过程。
在第n个修改周期内,UE2在寻呼消息中收到按需的系统信息的变更指示,知道按需的系统信息会变更。第n+1个修改周期到达后,网络侧广播变更的on-demand SI。UE2不需要发送on-demand SI请求。UE2先读MSI,通过SIB1检查on-demand SI中感兴趣的SIB的有效信息(areaID+valuetag),从而确定哪些SIB和自己存储的区域号和/或版本号不同,需要读取变更的 SIB;区域号和版本号与UE2已经存储的相同,则不需要再读取。UE2通过SIB1获取on-demand SI中感兴趣的SIB的调度信息,从而监听相应的SI窗口,接收变更的SIB。
示例三:UE进行小区重选系统信息变更指示(cell reselection SI change indication)的过程。
第n个修改周期内,UE3和UE4在寻呼消息中收到小区重选系统信息的变更指示,知道小区重选的系统信息会变更,小区重选的系统信息包括SIB3~SIB5。同时,SIB3~SIB5的有效信息(areaID、valuetag)发生变化,不影响SIB1,SIB1不变更。UE3对小区重选系统信息感兴趣,UE4不感兴趣。第n+1个修改周期到达后,UE3先读MSI,通过SIB1检查该组中SIB3~SIB5的有效信息(areaID+valuetag),从而确定SIB3和自己存储的区域号和/或版本号不同,需要读取变更的SIB3;SIB4、SIB5的区域号和版本号和UE3已经存储的相同,则不需要再读取。由于UE4不感兴趣,所以UE4不操作,可以休眠,节省功率。UE3通过SIB1获取SIB3的调度信息,从而监听相应的SI窗口,接收变更的SIB3。
示例四:UE进行系统信息消息(SI message)bitmap系统信息变更指示的过程。
第n个修改周期内,UE5和UE6在寻呼消息中收到SI message bitmap系统信息的变更指示{0001},从而知道SI message4变更,SI message1~3没有变更。同时,SI message4中的SIB的有效信息(areaID、valuetag)发生变化,不影响SIB1,SIB1不变更。UE5对SI message4感兴趣,UE6不感兴趣。第n+1个修改周期到达后,UE5先读MSI,通过SIB1检查相应SI message的有效信息(areaID、valuetag),从而确定SI message4和自己存储的区域号和/或版本号不同,需要读取变更的SI message4。由于UE6不感兴趣,所以UE6不操作,可以休眠,节省功率。UE5通过SIB1获取SI message4的调度信息,从而监听相应的SI窗口,接收变更的SI message4。
综上,本公开的上述实施例提供的系统信息的更新方法中,终端根据系统信息的变更指示确定哪些系统信息块组会变更,终端根据该变更指示能够准确的进行变更的系统信息的获取,从而减少不必要的系统信息的获取,节 省终端的功率。
