相关申请的交叉引用
本申请要求于2016年5月13日在中国提交的中国专利申请号No.201610320320.4的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其涉及一种系统消息发送方法、发送设备、接收方法、接收设备及存储媒介。
系统消息指小区内的公共消息。在传统蜂窝网中,终端通过读取系统消息获取小区内的完整信息,为了保证系统消息顺利接收,系统消息总是预占用部分时频资源。
以LTE(Long Term Evolution,长期演进)系统为例,LTE系统的系统消息主要分为MIB(Master Information Block,主系统信息块)和多个SIB(System Information Blocks,系统信息块)消息。UE(User Equipment,用户终端)新接入一个小区或广播消息发生改变时,都会接收系统消息(MIB/SIB)。系统消息包括:MIB、SIB1和SI(System Information),其中SI消息目前包含SIB2~SIB20,还可能继续扩展。
LTE系统的系统消息的发送有诸多限制和规定,并且随着无线通信系统业务多样化和终端类型不断演进,系统消息内容越来越多,占用的资源也越来越多,相应的会减少传输实际业务数据的可用资源。并且,系统消息的一些规定,也限制了其他功能的应用,例如MIB、SIB1固定占用子帧0、5,使得标准不得不规定寻呼子帧、MBSFN(多播/组播单频网络)子帧不能使用子帧0、5,进一步举例,带内中继(in-band relay)中,RN(RelayNode,中继节点)到UE的接入链路(access link)传输只能使用DeNB(施主基站)到RN这段回程链路(backhaul link)的MBSFN子帧,不仅限制了使用的资源,也加大了接入链路的传输时延。因此未来移动通信系统中需要考虑系统消息
传输机制的优化。

图8为本公开一些实施例的终端的结构框图。
下面将结合附图和实施例,对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开,但不用来限制本公开的范围。
系统消息传输周期及其变更如图1所示,不同填充图形的方块代表不同的系统消息。除ETWS(Earthquake and Tsunami Warning System,地震海啸报警系统)/CMAS(Commercial Mobile Alert System,商用移动通知系统)等少数几个消息外,系统消息的变更只能在特定的无线帧发生,由BCCH(Broadcast Control Channel,广播控制信道)修改周期(modification period)确定。在一个修改周期内,系统消息可能会发送多次,多次发送的系统消息内容相同。系统消息只能在修改周期的边界之后发生变化。当基站需要变更小区系统消息(全部或部分系统消息)时,首先需要在当前的修改周期(BCCH modification period(n))向UE发送“系统消息变更指示(Change notification)”,通知UE将发生的系统消息变化。基站在下一个修改周期(BCCH modification period(n+1))发送更新后的系统消息(Updated information)。
请参考图2,图2为本公开一些实施例的系统消息发送方法的流程示意图,该系统消息发送方法包括:
步骤S21:网络侧设备确定需要下发的每一条系统消息所属的集合,所述集合包括基本系统消息集合和专用系统消息集合;
步骤S22:所述网络侧设备确定所述每一条系统消息的传输方式,其中,所述基本系统消息集合中的所有系统消息的传输方式为广播传输方式,所述专用系统消息集合中的系统消息的传输方式包括广播传输方式和/或基于需求的专用信令传输方式;
步骤S23:所述网络侧设备根据确定的传输方式进行系统消息下发。
所述基于需求的专用信令传输方式是指:网络侧设备在接收到终端发送的下发所述专用系统消息集合中的系统消息的请求后,才向发送请求的所述终端下发所述终端请求的系统消息。
也就是说,上述步骤S23具体可以包括以下步骤:
步骤S231:所述网络侧设备判断是否接收到终端发送的下发所述专用系统消息集合中的系统消息的请求;
步骤S232:如果是,所述网络侧设备采用所述专用信令传输方式向所述终端下发所述终端请求的系统消息。
即,网络侧设备可以动态或者半静态调整专用系统消息集合中的系统消
息的传输方式,从而可以有效降低整个系统的广播开销,提升系统整体资源利用率。
上述实施例中,所述网络侧设备确定需要下发的每一条系统消息所属的集合之前,还可以包括:所述网络侧设备将需要下发的系统消息划分为基本系统消息集合和专用系统消息集合。
其中,系统消息集合的划分原则可以为:所述基本系统消息集合中的系统消息内容包括终端接入系统和/或空闲态终端进行小区选择/重选必须获知的参数,所述专用系统消息集合中的系统消息可以为除所述基本系统消息集合中的系统消息之外的其他系统消息,例如可以包括与终端能力相关的系统消息、与终端业务特性相关的系统消息以及与终端移动性相关的系统消息中的任意一种或多种的组合。
当然,随着需求的不断发展,上述基本系统消息集合和专用系统消息集合中的系统消息可以根据需求进行增减或重新划分,例如,可以根据需要将专用系统消息中的某一系统消息划分到基本系统消息集合中。
上述系统消息发送方法适用于各种类型的通信系统。
下面以LTE系统中的系统消息为例,对如何进行基本系统消息集合和专用系统消息集合划分进行说明。
下面首先对LTE系统中的各系统消息的内容和传输特点进行简单说明。
MIB:用于系统接入。MIB上传输几个比较重要的系统消息参数,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SFN(System Frame Number,系统帧号),在PBCH(Physical Broadcast Channel,物理广播信道)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(Orthogonal Frequency Division Multiplexing,正交频分复用)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消息)。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重传。
其他系统消息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(频分双工)邻频频点列表以及每个频点的重选参数、UTRA TDD(时分双工)邻频频点列表以及每个频点的重选参数。
SIB7:GERAN(GSM/EDGE无线接入网)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(家用基站)的名称。
SIB10:ETWS(地震及海啸预警系统)主信息(primary notification)。
SIB11:ETWS辅信息(secondary notification)。
SIB12:CMAS(商用移动通知系统)信息(CMAS notification)。
SIB13:获取跟一个或多个MBSFN(多播/组播单频网络)区域相关的MBMS(Multimedia Broadcast Multicast Service)控制信息的信息、。
SIB14~SIB20各有其针对的特性,不再一一描述。
本公开实施例中,所述基本系统消息集合中的系统消息内容可以包括LTE系统的MIB和SIB1~SIB8中的全部或者部分参数,比如下行带宽、系统帧号、TDD(时分双工)配置等。所述专用系统消息集合中的系统消息内容包括LTE系统的SIB9~SIB20中的全部或者部分参数。
本公开实施例中,所述网络侧设备可以通过以下方式确定所述专用系统消息集合中每一条系统消息的传输方式:
第一种传输方式确定方式为:根据预配置的系统消息传输方式确定所述专用系统消息集合中每一条系统消息的传输方式;
也就是说,所述网络侧可以预先为专用系统消息集合中的每一系统消息
配置一种传输方法。具体配置时,可以有多种方式。比如可以约定基站开机专用系统消息集合中的每一条系统消息都使用基于需求的专用信令传输;也可以通过参考历史数据等方式,为专用系统消息集合中的每一系统消息配置传输方式,例如,在历史数据中,当对某一系统消息感兴趣的终端超出预定门限值时,可以将该系统消息的传输方式配置为广播传输方式,当对某一系统消息感兴趣的终端未超出预设门限值时,可以将该系统消息的传输方式配置为专用信令传输方式。
第一种传输方式确定方式实现比较简单,适用于本公开实施例的系统消息发送方法执行的初期阶段。
第二种传输方式确定方式为:根据终端上报的辅助信息确定所述专用系统消息集合中每一条系统消息的传输方式。
具体的方法可以为:
所述网络侧设备接收终端上报的辅助信息,所述辅助信息中包括所述终端感兴趣或不感兴趣的所述专用系统消息集合中的系统消息的标识;
所述网络侧设备根据所述辅助信息,确定所述专用系统消息集合每一条系统消息的传输方式,具体包括以下情况:
1)当所述专用系统消息集合内的系统消息当前的传输方式为广播传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数低于预定门限值时,将所述系统消息的传输方式变更为专用信令传输方式;或
2)当所述专用系统消息集合内的系统消息当前的传输方式为广播传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数等于或高于预定门限值时,保持所述系统消息的传输方式为广播传输方式;或
3)当所述专用系统消息集合内的系统消息当前的传输方式为专用信令传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数低于所述预定门限值时,保持所述系统消息的传输方式为专用信令传输方式;或
4)当所述专用系统消息集合内的系统消息当前的传输方式为专用信令传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数等于或高于所述预定门限值时,将所定系统消息的传输方式变更为广播传输方式。
1)和2)两种情况要求接收专用系统消息集合内的使用广播方式传输的
系统消息的终端上报其接收的专用系统消息的标识信息以便网络判断系统内对该系统消息感兴趣的终端个数。
3)和4)两种情况,网络侧设备根据终端的请求确定对该系统消息感兴趣的终端个数。
第二种传输方式确定方式更贴合用户需求,能够实时反映用户所需,符合系统消息的传输资源开销小的原则。通常适用于本公开实施例的系统消息发送方法已运行一段时间的情况。
本公开实施例中,所述网络侧设备确定所述专用系统消息集合中每一条系统消息的传输方式之后,还需要将所述所述专用系统消息集合中的使用广播传输方式和/或使用专用信令传输方式传输的系统消息的编号或者标识通知终端。
本公开实施例中,所述网络侧设备可以通过以下几种方式,将所述专用系统消息集合中的使用广播传输方式和/或使用专用信令传输方式传输的系统消息的编号或者标识通知终端:
第一种通知方式:所述网络侧设备通过所述基本系统消息集合中的系统消息携带所述专用系统消息集合中的系统消息的传输方式指示信息;
第二种通知方式:所述网络侧设备通过新引入的广播消息携带所述专用系统消息集合中的系统消息传输方式指示信息。
新引入的广播消息可以为一条或多条。
第三种通知方式:所述网络侧设备通过专用信令消息携带所述专用系统消息集合中的系统消息传输方式指示信息。专用信令可以是RRC(无线资源控制)信令、MAC信令或者物理层信令。
第一种通知方式下,为了保证终端和网络对专用系统消息集合中各条系统消息传输方式理解的一致性,可以引入系统消息变更周期的概念。
具体的,当所述专用系统消息集合中的任何一条系统消息的传输方式发生变更时,所述网络侧设备在当前的基本系统消息变更周期通知终端专用系统消息集合中的系统消息的传输方式将发生变更和/或传输方式变更的专用系统消息的标识;并在当前的基本系统消息变更周期的下一个基本系统消息变更周期对传输方式发生变更的系统消息按照变更后的传输方式进行传输。
第二种通知方式下,同样也需要对新引入的广播消息引入一个消息变更周期,以保证终端和网络对专用系统消息集合中各条系统消息传输方式理解的一致性。
具体的,当所述专用系统消息中的任何一条系统消息的传输方式发生变更时,所述网络侧设备在所述广播消息变更周期通知终端所述专用系统消息集合中的系统消息的传输方式将发生变更和/或传输方式变更的专用系统消息的标识;并在当前的所述广播消息变更周期的下一个所述广播消息变更周期对对传输方式发生变更的系统消息按照变更后的传输方式进行传输。
上述各实施例中,所述基本系统消息集合内的系统消息和所述专用系统消息集合中的系统消息使用的广播过程可以是相同,也可以是分别独立的过程。具体的,所述基本系统消息集合内的系统消息和所述专用系统消息集合中的系统消息使用的物理资源和具体传输机制(比如重复次数、调度方式等)可以相同,也可以不同。物理资源可以是固定位置的,也可以是动态或者半静态的物理资源。对于动态或者半静态的物理资源,终端通过盲检获知系统消息的内容。
下面结合具体实施例,对上述的两种系统消息传输方式确定方式的使用方法举例进行说明。
请参考图3,图3为本公开一些实施例的系统消息发送方法的流程示意图,该系统消息发送方法包括:
步骤S31:网络侧设备确定需要下发的每一条系统消息所属的集合,所述集合包括基本系统消息集合和专用系统消息集合;
步骤S32:所述网络侧设备根据预配置的系统消息传输方式确定所述专用系统消息集合中每一条系统消息的传输方式;
步骤S33:所述网络侧设备将所述专用系统消息集合中的使用广播传输方式和/或使用专用信令传输方式传输的系统消息的编号或者标识通知终端;
步骤S34:所述网络侧设备根据确定的传输方式进行系统消息下发。
步骤S35:所述网络侧设备接收终端上报的辅助信息,所述辅助信息中包括所述终端感兴趣或不感兴趣的所述专用系统消息集合中的系统消息的标识:
步骤S36:所述网络侧设备根据所述辅助信息,重新确定所述专用系统消息集合每一条系统消息的传输方式,具体包括以下情况:
1)当所述专用系统消息集合内的系统消息当前的传输方式为广播传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数低于预定门限值时,将所述系统消息的传输方式变更为专用信令传输方式;或
2)当所述专用系统消息集合内的系统消息当前的传输方式为广播传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数等于或高于预定门限值时,保持所述系统消息的传输方式为广播传输方式;或
3)当所述专用系统消息集合内的系统消息当前的传输方式为专用信令传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数低于所述预定门限值时,保持所述系统消息的传输方式为专用信令传输方式;或
4)当所述专用系统消息集合内的系统消息当前的传输方式为专用信令传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数等于或高于所述预定门限值时,将所定系统消息的传输方式变更为广播传输方式。
步骤S37:所述网络侧设备将所述专用系统消息集合中的传输方式发生变更的系统消息的编号或者标识通知终端;
步骤S38:所述网络侧设备根据重新确定的传输方式进行系统消息下发。
本实施例中,同时使用了两种系统消息传输方式确定方式,即在系统运行的初始阶段,使用第一种传输方式确定方式(预配置的方式)确定专用系统消息集合中的每一系统消息的传输方式,在系统运行一段时间后,根据终端上报的辅助消息,使用第二种传输方式确定方式确定专用系统消息集合中的每一系统消息的传输方式,两种方式结合更贴合实际。
上述各实施例中,网络侧设备在进行系统消息下发时,无论是基本系统消息集合还是专用系统消息集合中的系统消息传输都可以有两种方式:
1)直接传输系统消息内容本身。
2)将系统消息可能的配置预配置在终端并编号,系统消息传输时只携带编号。
第二种方式可以进一步节省系统资源,降低系统开销。
同时,所述网络侧设备在进行系统消息下发时,可以首先判断终端中是
否配置有所述系统消息的内容和标识或者编号;如果是,所述网络侧设备下发所述系统消息时,仅下发所述系统消息的标识或编号;否则,所述网络侧设备下发所述系统消息的全部内容。

当所述专用系统消息集合内的系统消息当前的传输方式为专用信令传输方式,且预定时间内上报对所述系统消息感兴趣的终端个数等于或高于所述预定门限值时,将所定系统消息的传输方式变更为广播传输方式。
为了能够将述专用系统消息集合中的系统消息的传输方式通知终端,所述系统消息发送设备还包括:
通知模块,用于将所述专用系统消息集合中的使用广播传输方式和/或使用专用信令传输方式传输的系统消息的编号或者标识通知终端。

第一通知单元,用于通过所述基本系统消息集合中的系统消息携带所述专用系统消息集合中的系统消息的传输方式指示信息;或者,
第二通知单元,用于通过新引入的广播消息或者专用信令携带所述专用系统消息集合中的系统消息传输方式指示信息。
为了保证终端和网络对专用系统消息集合中各条系统消息传输方式理解的一致性,可以引入系统消息变更周期的概念。
具体的,所述第一通知单元具体用于当所述专用系统消息集合中的任何一条系统消息的传输方式发生变更时,在当前的基本系统消息变更周期通知终端专用系统消息集合中的系统消息的传输方式将发生变更和/或传输方式变更的专用系统消息的标识;在当前的基本系统消息变更周期的下一个基本系统消息变更周期对传输方式发生变更的系统消息按照变更后的传输方式进行传输。
