Description

系统信息传输方法、装置和系统、及计算机可读存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种系统信息传输方法、装置和系统、及计算机可读存储介质。
背景技术
在5G通信系统中，系统信息分为两种：最小集系统信息(Minimum System Information)和其他系统信息(other System Information)。其中，最小集系统信息包括MIB(Master Information Block，主信息块)和SIB(System Information Block，系统信息块)1，其他系统信息包括SIB2～SIB9等。不同的SIB中携带不同的内容。
最小集系统信息持续通过广播发送，而其他系统信息则是基于UE(User Equipment，用户设备)的请求，选择性地广播发送。例如，UE根据自身的业务需求，确定是否需要获取其他系统信息。如果需要获取其他系统信息，则UE发送系统信息请求，网络侧选择UE所请求的系统信息进行广播。
发送过系统信息请求的UE会去读取和存储网络侧广播的其他系统信息，而没有发送过系统信息请求的UE并不会关注网络侧广播的其他系统信息。当这些UE需要使用其他系统信息时，他们也会发送系统信息请求，网络侧会基于收到的系统信息请求再次广播被请求的其他系统信息，再次广播的其他系统信息和之前广播的其他系统信息可能是相同的，这样会造成无线资源浪费。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
为了便于理解本公开实施例提供的技术方案，下面先对系统信息进行介绍说明：
在5G通信技术中，系统信息是小区级的信息。系统信息分为最小集系统信息和其他系统信息。其中，最小集系统信息包括MIB和SIB1。其他系统信息包括除了MIB和SIB1以外的系统信息块，包括但不限于SIB2～SIB9。不同的系统信息携带不同的内容。
示例性地，不同的系统信息携带的内容如下：
MIB包含小区禁止状态信息和接收其他系统信息所需要的小区的基本物理层信息；
SIB1提供了其他系统信息块的调度信息和初始接入所需的信息；
SIB2包含小区重选信息，主要与服务小区有关；
SIB3包含与服务频率同频的相邻小区的小区重选相关的信息(包括频率共用的小区重选参数以及小区特定的重选参数)；
SIB4包含与服务频率异频的NR(New Radio，新空口)小区重选相关信息(包括频率共用的小区重选参数以及小区特定的重选参数)；
SIB5包含异接入技术小区重选相关信息(包括E-UTRA(Evolved Universal  Terrestrial Radio Access，演进的UMTS(Universal Mobile Telecommunications System，通用移动通信系统)陆地无线接入)频率共用的小区重选参数以及E-UTRAN小区特定的重选参数)；
SIB6包含ETWS(Earthquake and Tsunami Warning System，地震、海啸预警系统)主要通知；
SIB7包含ETWS辅助通知；
SIB8包含CMAS(Commercial Mobile Alert Service，商业移动告警服务)警告通知；
SIB9包含与GPS(Global Positioning System，全球定位系统)时间和UTC(Coordinated Universal Time，协调世界时)相关的信息。
除了上述SIB2～SIB9以外，还可以包括携带与MBMS(Multimedia Broadcast Multicast Services，多媒体广播多播业务)相关的信息的SIB，携带与车联网相关的信息的SIB等等。
UE根据自身能力的不同，可能需要用到其他系统信息中的部分或全部系统信息。例如，MIB和SIB1主要携带UE接入网络所必须的信息，所以UE都需要能够获取到MIB和SIB1。SIB2～SIB5主要携带小区重选的相关信息，对于固定UE，由于其位置不会发生变化，不需要进行小区重选，所以固定UE不需要获取SIB3～SIB8。对于不支持多媒体广播的终端，则不需要获取携带与MBMS相关的信息的SIB。
其他系统信息均在SI消息中传输。单个SI消息中可以携带一个或多个SIB，每个SIB只能包含在一个SI消息中。每个SI消息对应一个SI窗口，每个SI消息在对应的SI窗口中广播。各个SI窗口的长度相等，可以通过SIB1配置，单位通常为毫秒。不同的SI窗口相互间不重叠。
图1是本发明实施例提供的系统信息传输系统示意图。参见图1，该系统包括基站100和终端200。基站100广播系统消息。终端200接收基站100广播的系统信息，基于获取到的系统信息接入网络，或者实现相应的业务功能，例如小区重选等。
图2是根据一示例性实施例示出的一种系统信息传输方法的流程图，该方法可以由基站(例如图1中的基站100)执行。本实施例的方法也可以称为系统信息广播方法。参见图2，该系统信息传输方法包括：
在步骤S11中，发送寻呼消息。
该寻呼消息包括指示信息，该指示信息用于指示将在指定时段内广播其他系统信息。
在步骤S12中，在指定时段内广播指示信息所指示的其他系统信息。
可选地，该指示信息可以包括多个标识，每个标识对应唯一一个SIB，每个标识用于指示对应的SIB是否将在指定时段内广播。这里的标识可以为多个比特位，每个比特位对应唯一一个SIB。例如，假设其他系统信息包括8个SIB，则标识包括8个比特位，每个比特位对应一个SIB，当其中一个比特位为1(或0)时，表示对应的SIB将在指定时段内广播，当其中一个比特位为0(或1)时，表示对应的SIB不会在指定时段内广播。
可选地，该指示信息可以包括一个标识，该标识用于指示所有的SIB是否将在指定时段内广播。这里的标识可以采用一个比特位，当该比特位为1(或0)时，表示所有SIB将在指定时段内广播，当其中一个比特位为0(或1)时，表示所有SIB不会在指定时段内广播。
可选地，该指示信息可以包括一个标识，该标识可以用于指示任意一个或多个SIB将在指定时段内广播。这里的标识可以采用一个比特位，当该比特位为1(或0)时，表示将有SIB在指定时段内广播，当其中一个比特位为0(或1)时，表示没有SIB在指定时段内广播。
可选地，指定时段包括寻呼消息所在无线子帧后第一个系统信息SI窗口起的至少一个系统信息SI窗口。
可替换地，该指定时段还可以为寻呼消息所在无线子帧后的下一个修改周期。
其中，寻呼消息所在无线子帧需要通过无线帧号和无线子帧号共同确定，例如，无线帧10的无线子帧3，无线帧15的无线子帧6等。
可选地，该寻呼消息还包括系统信息修改通知，系统信息修改通知用于在下一个修改周期发送更新后的系统信息。当然，也可以不包括系统信息修改通知。
在本实施例中，修改周期可以为BCCH(Broadcast Control Channel，广播控制信道)修改周期。
可选地，该寻呼消息为DCI(Downlink Control Information，下行控制信息)中携带的短消息(short message)或者DCI指示的PDSCH(Physical Downlink  Shared Channel，物理下行共享信道)上发送的寻呼(Paging)消息。
可选地，该方法还包括：
接收终端发送的系统信息请求，该系统信息请求包括SIB标识。
值得说明的是，前述步骤S11-S12与上述可选步骤可以任意组合。
图3是根据一示例性实施例示出的一种系统信息传输方法的流程图，该方法可以由终端(例如图1中的终端200)执行。本实施例的方法也可以称为系统信息获取方法。参见图3，所述系统信息传输方法包括：
在步骤S21中，接收寻呼消息。
该寻呼消息包括指示信息，该指示信息用于指示将在指定时段内广播其他系统信息。
在步骤S22中，根据指示信息，接收在指定时段内广播的其他系统信息。
关于指示信息和指定时段的描述参见图1相关实施例，在此省略详细描述。
可选地，该寻呼消息为DCI中携带的短消息或者DCI指示的PDSCH上发送的寻呼Paging消息。
可选地，该方法还包括：
当未存储有自身所需的其他系统信息时，从接收到的其他系统信息中读取自身所需的其他系统信息，并存储读取到的自身所需的其他系统信息。
可选地，根据指示信息，接收在指定时段内广播的其他系统信息，包括：
当未存储有自身所需的其他系统信息时，接收指定时段内广播的其他系统信息；
相应地，该方法还包括：从接收到的其他系统信息中读取自身所需的其他系统信息，并存储读取到的自身所需的其他系统信息。
可选地，接收在指定时段内广播的其他系统信息，包括：
从SIB1中获取其他系统信息的调度信息；
基于调度信息，确定寻呼消息所在无线子帧后第一个系统信息SI窗口起的至少一个系统信息SI窗口；
在确定出的至少一个SI窗口中的一个SI窗口接收其他系统信息。
可选地，该方法还包括：
发送系统信息请求，系统信息请求包括SIB标识。
值得说明的是，前述步骤S21-S22与上述可选步骤可以任意组合。
图4是根据一示例性实施例示出的一种系统信息传输方法的流程图。参见图4，该系统信息传输方法包括：
在步骤S31中，基站发送寻呼消息。
相应地，终端接收基站发送的寻呼消息。这里的终端，可以是基站所对应的小区中的全部或者部分终端，包括空闲状态的终端和连接状态的终端。
该寻呼消息包括指示信息，该指示信息用于指示将在指定时段内广播其他系统信息。
在一种可选的实施方式中，该指示信息可以包括多个标识，每个标识对应唯一一个SIB，每个标识用于指示对应的SIB是否将在指定时段内广播。这里的标识可以为多个比特位，每个比特位对应唯一一个SIB。例如，假设其他系统信息包括8个SIB，则标识包括8个比特位，每个比特位对应一个SIB，当其中一个比特位为1(或0)时，表示对应的SIB将在指定时段内广播，当其中一个比特位为0(或1)时，表示对应的SIB不会在指定时段内广播。采用这种方式，可以便于终端确定哪些SIB将被广播，进而确定后续动作。
在另一种可选的实施方式中，指示信息包括一个标识，该标识用于指示所有的SIB是否将在指定时段内广播。这里的标识可以采用一个比特位，当该比特位为1(或0)时，表示所有SIB将在指定时段内广播，当其中一个比特位为0(或1)时，表示所有SIB不会在指定时段内广播。采用这种方式，指示信息占用的比特位少，节省资源。
在又一种可选的实施方式中，也可以将上述两种方式结合使用，例如，当将在指定时段内广播所有的SIB时，指示信息为一个标识；当将在指定时段内广播部分SIB时，指示信息包括多个标识，分别指示将要广播的SIB。
可选地，该寻呼消息还包括系统信息修改通知，系统信息修改通知用于指示在下一个修改周期发送更新后的系统信息。
在本实施例中，修改周期可以为BCCH修改周期。
如前所述，系统信息通常在SI窗口中发送。因此，指定时段也可以以SI窗口为单位。示例性地，指定时段可以包括寻呼消息所在无线子帧后第一个系统信息SI窗口起的至少一个系统信息SI窗口。
也就是说，指定时段可以为寻呼消息所在无线子帧后第一个系统信息SI窗口。或者，指定时段可以为寻呼消息所在无线子帧后第一个系统信息SI窗口起 的至少两个SI窗口。
在一种情况下，当采用至少两个SI窗口广播其他系统信息时，连续的两个的SI窗口可以携带相同的SIB。例如，如果一条SI消息足以携带所有需要广播的其他系统信息，在每条SI消息需要一个SI窗口传输的前提下，为了提高终端接收到其他系统信息的可能，可以采用至少两个SI窗口重复广播需要广播的其他系统信息。
在另一种情况下，当采用至少两个SI窗口广播其他系统信息时，连续的两个SI窗口也可以携带不同的SIB。例如，如果需要多条SI消息才能携带所有需要广播的其他系统信息，在每条SI消息需要一个SI窗口传输的前提下，指定时段需要包括多个SI窗口，即基站需要在多个SI窗口广播所有需要广播的其他系统信息。
基站发送寻呼消息，可以在需要广播其他系统信息之前发送。例如，可以在接收到一个或多个终端发送的系统信息请求之后，基站确定需要广播其他系统信息，则发送携带有指示信息的寻呼消息。因此，本实施例的方法还可以包括：终端发送系统信息请求，基站接收终端发送的系统信息请求，系统信息请求包括SIB标识。又例如，可以由基站主动决定需要广播其他系统信息，在广播其他系统信息之前发送携带有指示信息的寻呼消息。
需要说明的是，收到寻呼消息的终端可以是发送过系统信息请求的终端，也可以是未发送过系统信息请求的终端。
SIB标识用于指示终端所需的其他系统信息。可选地，SIB标识可以为SIB编号，或者随机接入码的索引，随机接入码的索引与SIB编号之间存在一一映射关系，因此，可以作为SIB标识指示终端所需的其他系统信息。
需要说明的是，随机接入码的数量大于SIB的数量，例如随机接入码的数量为64个，而SIB的数量为9个，则可以从64个随机接入码中选择9个随机接入码与SIB关联。
可选地，该寻呼消息为DCI中携带的短消息或者DCI指示的PDSCH上发送的寻呼Paging消息。
在步骤S32中，基站在指定时段内广播其他系统信息。
在该步骤S32中，基站广播指示信息所指示的其他系统信息。
在步骤S33中，终端确定是否已存储自身所需的SI。
若未存储自身所需的SI，则执行步骤S34，若已存储自身所需的SI，则退 出当前流程。
在一种可能的实施方式中，该步骤S33可以包括：
第一步、终端可以根据自身的能力，确定自身所需的SI，例如，若终端具有移动能力，则该终端需要支持小区重选，因此，该终端所需的SI包括SIB2～SIB5。
第二步、终端判断本地存储的信息中是否包括自身所需的SI，例如终端可以在本地的指定存储空间查找已存储的系统信息，并确定自身所需的SI是否包含在查找到的已存储的系统信息中。
在另一种可能的实施方式中，终端可以在将所需的SI存储在本地之后，设置一个标识位，指示已存储自身所需的SI，此时，可以根据该标识位确定是否已存储自身所需的SI。
需要说明的是，步骤S33和S34之间没有先后顺序。
在步骤S34中，终端接收在指定时段内广播的其他系统信息。
该步骤S34可以包括：
第一步、从SIB1中获取其他系统信息的调度信息；其中，其他系统信息的调度信息可以指示其他系统信息是否广播、是否发生修改以及在哪个时频资源上广播。
第二步、基于调度信息，确定寻呼消息所在无线子帧后的第一个系统信息SI窗口起的至少一个系统信息SI窗口。
调度信息可以包含在调度信息列表(SchedulingInfoList)中，通过调度信息可以确定SI窗口长度、每条SI消息对应的SI窗口的起始位置(一个SI周期内的起始帧和起始子帧)等。
第三步、在确定出的至少一个SI窗口中的一个SI窗口接收其他系统信息。
在该第一步中，SIB1可以是终端预先获取并存储在本地的，可以直接从本地读取SIB1中所包含的其他系统信息的调度信息。或者，SIB1也可以是终端在确定自身未存储所需的SI之后接收的。
在步骤S35中，终端从接收到的其他系统信息中，获取自身所需的SI。
该步骤S35可以包括：终端从接收到的其他系统信息中读取自身所需的其他系统信息，并存储读取到的自身所需的其他系统信息。
在指示信息指示所有的SIB将在指定时段内广播的情况下，终端能够接收到所有的SIB，因此，必然可以从接收到的其他系统信息中获取到自身所需的 SI。
在指示信息指示部分SIB将在指定时段内广播的情况下，终端接收到的SIB中可能不包括自身所需的SI。此时，在步骤S34之前，该方法还可以包括：根据指示信息确定指示信息所指示的其他系统信息是否包括自身所需的SI。相应地，步骤S34可以包括：当指示信息所指示的其他系统信息包括自身所需的SI时，接收在指定时段内广播的其他系统信息。当指示信息所指示的其他系统信息不包括自身所需的SI时，则不接收在指定时段内广播的其他系统信息，即退出当前流程。
通过上述步骤S33～S35实现了终端根据指示信息，获取自身所需的其他系统信息。需要说明的是，在本实施例中，是当未存储有自身所需的其他系统信息时，接收指定时段内广播的其他系统信息；然后从接收到的其他系统信息中读取自身所需的其他系统信息，并存储读取到的自身所需的其他系统信息。而在其他实施例中，也可以直接根据指示信息接收指定时段内广播的其他系统信息，当未存储有自身所需的其他系统信息时，再从接收到的其他系统信息中读取自身所需的其他系统信息，并存储读取到的自身所需的其他系统信息。
本公开实施例通过在寻呼消息中携带指示信息，使得终端在收到寻呼消息之后，可以知道将在何时广播其他系统信息。如果终端需要其他系统信息，无需发送系统信息请求，直接根据指示信息接收其他系统信息，即可获取到终端需要的其他系统信息，减少了系统信息请求的数量并降低了重复广播其他系统信息的频率，因此，可以减少无线资源浪费。
此外，对于需要获取其他系统信息的终端而言，由于知道了广播其他系统信息的时间，终端只需要在指定时段内接收其他系统信息，而在其他时间可以保持休眠状态，而无需在发送系统信息请求之后一直监听SIB1以获取其中的调度信息，因此，本公开提供的方法可以降低终端的能耗。
