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发明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、本发明的一些方面相一致的装置和方法的例子。

应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,

本公开提供的技术方案适用于5G网络。本公开中涉及的执行主体包括:基站和用户设备(User Equipment,UE),其中,基站用于可以是设置有大规模天线阵列的基站、子基站等。用户设备UE可以是用户终端、用户节点、移动终端或平板电脑等。在具体实现过程中,基站和用户设备各自独立,同时又相互联系,共同实现本公开提供的技术方案。
首先,对本公开应用场景中涉及的上述三类系统信息(System Information,SI)的传输方式进行简单介绍:
5G网络系统中,基站可以采用较短的周期间隔比如1分钟、周期性广播上述第一类系统信息,该第一类系统信息也可以称为系统信息最小集minimum SI,包括用户设备进行小区选择和接入的必要系统信息,比如:MIB、SIB1、SIB2。
对于第二类系统信息,基站需要根据用户设备发送的请求信息,利用预设广播时间窗口,向用户设备所在的小区进行广播,在确定发送请求的用户设备接收到所需系统信息后,停止广播上述系统信息。因此,上述第二类系统信息属于应用户设备的请求而短时广播的系统信息。本公开实施例中,可以假设上述第二类系统信息包括:SIB3~SIB20。
第三类系统信息也属于基站周期性广播的系统信息,但其优先级低于上述第一类系统信息,因此,基站可以使用更长的周期间隔比如5分钟、周期性广播第三类系统信息。本公开实施例中,可以假设上述第三类系统信息包括:SIB21~SIBn。
本公开主要是针对上述第二类系统信息的请求获取时机而提供的一种技术方案。
参照图1根据一示例性实施例示出的一种请求获取系统信息的方法流程图,可以应用于5G网络的用户设备中,所述方法可以包括:
在步骤11中,接收基站广播的系统消息,确定已获取系统信息;
本公开实施例中,上述已获取系统信息中至少包括:minimum SI,如MIB、SIB1、SIB2,还可以包括部分第二类系统信息和/或第三类系统信息。
在步骤12中,根据所述已获取系统信息和需要的系统信息,确定待请求获取的目标系统信息;
本公开实施例中,目标系统信息是指上述第二类系统信息,该类系统信息属于用户设备接入网络的必要信息,可以在用户设备准备发起随机接入小区网络之前请求获取。
本公开中,根据用户设备的设备类型、业务类型等类别信息的不同,用户设备随机接入网络所需要的具体系统信息也可以不同。以用户设备UE1为例,假设UE1本次接入网络所需要的系统信息包括:MIB、SIB1、SIB2、SIB3、SIB4、SIBn。假设步骤11确定的已获取系统信息为:MIB、SIB1、SIB2、SIB3、SIBn。则经过比较可知,用户设备UE1当前时刻假设为T1时刻,需要请求获取的系统信息为:SIB4,即待请求获取的目标系统信息为:SIB4。
在步骤13中,确定当前时刻与所述目标系统信息的预设广播时间窗口之间的时间关系;
上述实施例示出了步骤12确定的目标系统信息的数量为1的情况。在本公开其他实施例中,步骤12确定的目标系统信息也可以是多个。对于多个目标系统信息的情况,系统可以按照下述步骤确定每一个目标系统信息的请求时机。下面仍以一个目标系统信息进行具体说明:
在LTE系统中,系统已约定好每个系统信息的广播时间窗口,比如,对于SIB4,系统可以约定在每个第一广播窗口W1即minimum SI的广播窗口结束后的预设时长Δt,通过预设第四广播窗口W4广播系统信息SIB4。上述预设第四广播窗口W4对应的窗口时长可以是10分钟。基于此,用户设备可以根据上述信息以及最近监测到第一广播窗口W1的时间,精确计算出目标第四广播窗口W4的时间信息。
在本公开另一实施例中,系统也可以约定第四广播窗口W4的起始时
刻比如8:00、窗口时长如10分钟周期、间隔时长即每相邻两个第四广播窗口W4之间的时间间隔比如30分钟,从而准确计算出每个第四广播窗口W4的时间信息。
上述第四广播窗口W4的时间信息可以包括:预计达到时间、对应时间范围等信息。
仍以目标系统信息为SIB4为例,在用户设备确定SIB4对应的第四广播窗口W4的窗口范围为:T2~T3之后,假设上述T2~T3具体为:8:00~8:10时刻,则,本公开可以采用以下任一方式确定当前时刻T1与上述第四广播窗口W4的窗口范围:T2~T3之间的时间关系:
第一种方式,参见图2根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,所述步骤13可以包括:
在步骤131中,判断当前时刻是否处于所述目标系统信息的一个预设广播时间窗口内;若否,执行下述步骤132。
在步骤132中,确定所述当前时刻距离最近的所述预设广播时间窗口的第一间隔时长。
参照图3-1根据一示例性实施例示出的第一间隔时长的示意图。假设在步骤12中,UE1确定待请求目标系统信息为SIB4的时刻即当前时刻T1为7:50;在步骤13中,UE1确定的、用于广播SIB4的最近预设广播时间窗口W4的时间范围为:T2~T3,例如,具体时间范围为:8:00~8:10。可知,当前时刻T1处于预设广播时间窗口W4之外,则计算当前时刻T1距离最近预设广播时间窗口的第一间隔时长Δt1,即Δt1=T2-T1=8:00-7:50=10分钟。
第二种方式,参见图4根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,在图2所示实施例的基础上,所述步骤13除了包括上述步骤131,还可以包括:
在步骤133中,若所述当前时刻处于所述预设广播时间窗口内,确定所述当前时刻与所述预设广播时间窗口的起始时刻之间的第二间隔时
长。
参照图3-2根据一示例性实施例示出的第二间隔时长的示意图。假设上述步骤12确定待请求目标系统信息SIB4的当前时刻T1为8:03。在步骤13中,UE1确定的、用于广播SIB4的预设广播时间窗口T2~T3的具体时间范围仍为:8:00~8:10。则当前时刻T1处于上述SIB4的预设广播时间窗口W4内。
根据上述预设广播时间窗口W4的起始时刻T2即8:00和当前时刻T1计算第二间隔时长Δt2,则Δt2=T1-T2=8:03-8:00=3分钟。
在步骤14中,若所述时间关系满足预设请求触发条件,向所述基站发送用于获取所述目标系统信息的请求信息。
根据上述当前时刻与目标预设广播时间窗口之间的时间位置关系的不同,上述步骤14的实施也可以包括以下至少三种情况:
第一种情况,对应上述步骤13的第一种实施方式,参见图5-1根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,上述步骤14可以包括:
在步骤1411中,判断所述第一间隔时长是否大于第一预设时长阈值;
在步骤1412中,若所述第一间隔时长大于所述第一预设时长阈值,向所述基站发送用于获取所述目标系统信息的请求信息。
本公开实施例中,步骤14中的预设请求触发条件是:所述第一间隔时长Δt1大于第一预设时长阈值ΔT1。
从上述示例可知,Δt1>ΔT1,则UE1可以向基站发送用于请求获取目标系统信息SIB4的请求信息,该请求信息可以包括:目标系统信息的信息标识。
在本公开另一实施例中,参见图5-2根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,在图5-1所示实施例的基础上,所述步骤14还可以包括:
在步骤1413中,若所述第一间隔时长小于等于所述第一预设时长阈值,从所述最近的预设广播时间窗口检测所述目标系统信息。
相反,若Δt1≤ΔT1,比如,ΔT1=5分钟,而Δt1=2分钟,则用户设备UE1可以在图3-1所示的最接近预设广播时间窗口W4到来时,检测该广播时间窗口W4内是否广播有目标系统信息SIB4。
此处需要说明的是,上述即将到来的目标预设广播时间窗口如图3-1的W4中可能广播有目标系统信息,如图3-1所示,假设在T1时刻如7:50之前,有另一用户设备UE2向基站发送了获取SIB4的请求信息,基站响应UE2的请求信息,在预设广播时间窗口W4中向小区内的用户设备广播SIB4。则UE1无需再单独发送一个请求信息,即可在上述预设广播时间窗口W4内检测到SIB4,实现共享目标系统信息的目的,同时由于节约了基站响应请求信息的时长,有效缩短了UE1获取目标系统信息的时延。
在步骤1414中,若在所述预设广播时间窗口内未检测到所述目标系统信息,向所述基站发送所述请求信息。
在本公开另一实施例中,仍如图3-1所示,假设在T1时刻如7:50之前,没有其他用户设备向基站发送用于请求获取SIB4的请求信息,则上述预设广播时间窗口W4内也可能未广播目标系统信息SIB4,此种情况下,用户设备仍需要向基站发送所述用于请求获取目标系统信息的请求信息。
上述请求信息的具体发送时机,视预先约定的目标子帧在预设广播时间窗口W4中的预置位置而定,其中,所述目标子帧是指承载SIB4的子帧。若上述目标子帧的位置是基站在预设广播时间窗口W4中随机指定的,则可以在上述预设广播时间窗口W4检测完毕后再发送上述请求信息;若上述目标子帧的位置是预置固定位置,则UE1在接收完所述目标子帧后即可向基站发送所述请求信息。
第二种情况,参照图6-1根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,上述步骤14可以包括:
在步骤1421中,判断所述第二间隔时长是否大于第二预设时长阈值;
根据判断结果不同,可以包括以下至少三种执行方式,分别为:若是,执行下述步骤1422或图6-2中1423;若否,执行图6-3中的步骤1424。
第一执行方式,在步骤1422中,若所述第二间隔时长大于所述第二预设时长阈值,向所述基站发送用于获取所述目标系统信息的请求信息。
本公开实施例中,步骤14中的预设请求触发条件是:所述第二间隔时长Δt2大于第二预设时长阈值ΔT2。
仍假设一个预设广播时间窗口的窗口时长为10分钟,系统可以约定承载SIB4的目标子帧在整个广播时间窗口W4中位置。参照图7-1根据一示例性实施例示出的一种第二间隔时长的示意图,在图3-2的基础上,假设,预设广播时间窗口W4包括:序列号为0~9的10个子帧,预置第4号子帧用于承载SIB4。即第4号子帧为目标子帧。
本公开实施例中,系统可以根据上述目标子帧的位置,设置第二预设时长阈值。
图7-1属于上述图3-2的一种具体情况,假设当前时刻T1所在的预设广播时间窗口T2~T3的具体时间范围仍为:8:00~8:10,ΔT2=5分钟,若所述Δt2>ΔT2,如图7-1所示,表示UE1已经错过了当前窗口W4中SIB4的检测时机,此种情况下,可以包括两种执行情况:
第一种执行方式,向所述基站发送用于获取所述目标系统信息的请求信息。
第二种执行方式,参照图6-2根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,在图6-1所示实施例的基础上,上述步骤142除了包括步骤1421,还可以包括:
在步骤1423中,若所述第二间隔时长大于所述第二预设时长阈值,确定所述当前时刻距离下一个所述预设广播时间窗口的第三间隔时长;
参照图3-3根据一示例性实施例示出的一种第三间隔时长的结构示
意图。在Δt2>ΔT2的基础上,计算当前时刻T1距离即将到来的下一个预设广播时间窗口W4’的第三间隔时长Δt3。
在步骤1424中,判断所述第三间隔时长是否大于所述第三预设时长阈值;
本公开实施例中适用于UE1属于非时延敏感设备的情况,此种情况下,UE1可以等待较长时间即第三预设时长阈值ΔT3大于上述第一预设时长阈值ΔT1,如果UE1错过了当前时刻T1所在预设广播时间窗口内SIB4的检测时机,可以根据上述第三预设时长阈值确定是否要等到下一个预设广播时间窗口到来后继续检测SIB4。
在步骤1425中,若所述第三间隔时长大于所述第三预设时长阈值,向基站发送用于获取所述目标系统信息的请求信息。
如图3-3所示,如果当前时刻T1距离下一个预设广播时间窗口W4’的第三间隔时长Δt3,大于第三预设时长阈值ΔT3,即Δt3>ΔT3,超过了等待期限,向所述基站发送所述请求信息。
参照图6-3根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,在图6-2所示实施例的基础上,上述步骤142还可以包括:
在步骤1426中,若所述第三间隔时长小于等于所述第三预设时长阈值,从所述下一个所述预设广播时间窗口检测所述目标系统信息。
相反,如图3-3所示,如果当前时刻T1距离下一个预设广播时间窗口W4’的第三间隔时长Δt3没有超过第三预设时长阈值ΔT3,即Δt3≤ΔT3,则可以在下一个预设广播时间窗口W4’到来后,继续检测SIB4。
在步骤1427中,若在所述下一个所述预设广播时间窗口未检测到所述目标系统信息,向所述基站发送用于获取所述目标系统信息的请求信息。
同上,如果在下一个预设广播时间窗口W4’中也没有检测到SIB4,再向基站发送用于请求获取SIB4的请求信息。
参照图6-4根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,在图6-1所示实施例的基础上,上述步骤142除了包括步骤
1421,还可以包括:
在步骤1428中,若所述第二间隔时长小于等于所述第二预设时长阈值,从所述当前时刻所在的所述预设广播时间窗口检测所述目标系统信息;
在本公开另一实施例中,若所述Δt2≤ΔT2;说明UE1还没错过当前所在预设广播时间窗口中SIB4的检测位置。参照图7-2根据一示例性实施例示出的另一种第二间隔时长的示意图,图7-2属于上述图3-2的另一种具体情况,如图7-2所示,T1时刻还未超过预设广播时间窗口W4中目标子帧即第4号子帧对应时刻,UE1有可能会在当前广播时间窗口W4内检测到SIB4。同上,若基站响应其他用户设备如UE2的请求,在当前广播窗口W4内广播有SIB4,则UE1可以共享接收该目标系统消息。
在步骤1429中,若在所述预设广播时间窗口内未检测到所述目标系统信息,向基站发送所述请求信息。
相反,若当前广播窗口W4内没有广播SIB4,在该广播时间窗口W4结束时或者检测完目标子帧后,UE1仍没有检测到SIB4,则UE1向基站发送所述请求信息。
参照图8根据一示例性实施例示出的另一种请求获取系统信息的方法流程图,在图1所示实施例的基础上,在上述步骤11之前,所述方法还包括:
在步骤10中,获取预设请求触发条件信息,所述预设请求触发条件信息包括以下至少一项:第一预设时长阈值、第二预设时长阈值、第三预设时长阈值。
本公开实施例中,基站可以向用户设备广播上述预设请求触发条件信息。本公开一实施例中,为节约系统广播资源,减少信令开销,基站可以将上述预设请求触发条件信息与上述第一类系统信息即minimum SI通过相同的广播时间窗口进行周期性广播,确保用户设备可以及时获取到上述预设触发条件信息。
综上,本公开提供的请求获取系统信息的方法,在用户设备确定需
要获取的目标系统信息的当前时刻,并不立即向基站发送用于获取目标系统信息的请求信息,而是首先根据预设请求触发条件在当前时刻所在的、或者即将到来的目标系统信息的预设广播时间窗口内,检测上述目标系统信息,若检测到,可以有效减少目标系统信息的获取时延,并减少用户设备向基站发送请求信息的次数,若未检测到,向基站发送所述请求信息,从而节约空口资源,提高空口资源的利用率。
相应的,本公开还提供了一种发送系统信息的方法,应用于5G网络的基站中,参照图9根据一示例性实施例示出的一种发送系统信息的方法流程图,所述方法可以包括以下步骤:
在步骤21中,向信号覆盖区域内的用户设备广播系统消息,所述系统消息至少包括:系统信息最小集合;
上述系统消息至少包括周期性发送的第一类系统信息即系统信息最小集合。
对应上述步骤11,以使用户设备确定以获取的系统信息。
在步骤22中,接收用户设备根据预设请求触发条件发送的、用于获取目标系统信息的请求信息,其中,所述目标系统信息为需要根据用户请求而下发的系统信息;
对应上述步骤14,接收用户设备根据预设请求触发条件发送的请求信息,所述请求信息用于获取一个目标系统信息。
在步骤23中,通过预设广播时间窗口发送所述目标系统信息;
响应用户设备的请求,利用预设广播时间窗口向用户设备所在小区广播所述目标系统信息。其中,上述预设广播时间窗口是基站可以预先约定好的预设广播时间窗口信息计算而得,上述预设广播时间窗口信息可以包括:用于广播目标系统信息如SIB4的广播窗口的开始时刻、广播时长、周期间隔等信息。
基站根据接收到请求信息的时间信息,根据上述预设广播时间窗口信息可以推断出在哪个预设广播时间窗口内广播上述目标系统信息。
在步骤24中,在确定所述用户设备接收到所述目标系统信息之后,停止广播所述目标系统信息。
本公开实施例中,当发送请求信息的用户设备如UEn在请求之后接收到目标系统信息,会向基站发送目标系统信息已获取的反馈消息。基站在接收到UEn发送的反馈消息后,停止向小区周期性广播SIB4。但在,开始广播到停止广播的时间范围内,其他需要SIB4的用户设备可以共享获取上述目标系统信息即SIB4,从而减少目标系统信息的广播次数,节约系统空口资源。
参照图10根据一示例性实施例示出的另一种发送系统信息的方法流程图,在图9所示实施例的基础上,在上述步骤22之前,所述方法还可以包括:
在步骤20中,广播所述目标系统信息的预设请求触发条件,以使所述用户设备在确定待请求系统信息后,根据所述请求触发条件向所述基站发送所述请求信息。
在本公开另一实施例中,上述步骤20可以与步骤21合并,即可以在基站向用户设备广播系统信息最小集时一并广播第二类系统信息的请求触发条件,其中包括所述目标系统信息的请求触发条件。
在本公开另一实施例中,在预设请求触发模式确定的情况下,基站也可以仅向用户设备发送上述请求触发模式中的预设触发条件信息,即上述第一预设时长阈值、第二预设时长阈值、第三预设时长阈值中的一个或多个。
采用本公开提供的发送系统信息的发送,可以减少请求触发条件的信息量,从而进一步节约系统空口资源。
