Description

一种定位辅助信息的广播方法、定位服务器及RAN节点
相关申请的交叉引用
本申请要求于2019年8月14日提交的申请号为201910761766.4,发明名称为“一种定位辅助信息的广播方法、定位服务器及RAN节点”的中国专利申请的优先权,其通过引用方式全部并入本文。
技术领域
本公开涉及通信技术领域,尤其涉及一种定位辅助信息的广播方法、定位服务器及RAN节点。
背景技术
目前在新空口(New Radio,NR)中,在实现定位辅助信息的广播时,大致流程可以为,定位管理实体(Location Management Function,LMF)将所需要广播的定位辅助信息发送给基站,基站将收到的定位辅助信息存储,并将其通过系统消息(System Information,SI)广播下去,然后终端无线资源控制(Radio Resource Control,RRC)层收到定位辅助信息的广播时,将其递交给LTE定位协议(LTE Positioning Protocol,LPP)进行处理。
此外,在NR的SI中,其发送方式可以分为两类,包括周期性广播以及基于终端请求分配(on-demand)的广播。其中,周期性广播方式为,在按照公式计算出的SI消息对应的SI时间窗口中,网络侧一直发送该SI消息;基于终端请求的广播方式为,如果没有终端请求,网络侧不发送该SI消息,若终端发送请求给网络侧,则网络侧再按照公式计算出的SI消息对应的SI时间窗口中,在一段时间内发送该SI消息。
虽然定位辅助信息的广播可以分为上述两种方式,但如何决定是周期性广播还是基于终端请求分配的广播,目前还没有解决方案。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
如图1所示,为本公开实施例中定位辅助信息的广播方法的步骤流程图之一,该方法包括如下步骤:
步骤101:向无线接入网RAN节点发送广播指示消息,所述广播指示消息中携带有定位辅助信息的广播方式指示信息。
具体的,定位服务器可以向无线接入网(Radio Access Network,RAN)节点发送广播指示消息,当然该广播指示消息中携带有定位辅助信息的广播方式指示信息,从而使得RAN节点能够根据该广播方式指示信息,确定采用何种方式对定位辅助信息进行广播。
其中,该广播方式指示信息包括下述信息中的至少一种:
其一,是否需要对定位辅助信息进行周期性广播的指示信息。
该种情况下,即定位服务器在广播指示消息中对该定位辅助信息是否需要一直广播进行指示;
其二,所述定位辅助信息的广播优先级的指示信息。
具体的,广播优先级可以采用高低优先级来指示,也可以定义预设范围的数值,根据数值的高低来确定优先级。
其三,对所述定位辅助信息进行周期性广播的指示信息。
在该种情况下,定位服务器在广播指示消息中对定位辅助信息的广播方式进行明确指示,即指示对定位辅助信息进行周期性广播。
其四,基于终端请求对所述定位辅助信息进行广播的指示信息。
在该种情况下,定位服务器在广播指示消息中对定位辅助信息的广播方式进行明确指示,即指示基于终端请求分配的方式,对定位辅助信息进行广播。
下面对上述广播方式指示信息中,是否需要对所述定位辅助信息进行周期性广播的指示信息以及定位辅助信息的广播优先级的指示信息进行具体举例说明。
例如,定位服务器可以基于自身规定的原则,确定需要广播的定位辅助信息是否需要一直广播,或者确定需要广播的定位辅助信息的广播优先级。例如某定位辅助信息已经由提供商付费,则定位服务器可以将该定位辅助信息设置为需要进行周期性广播,即需要一直广播,或者设置广播优先级为高优先级(也可以是一个高优先级的值);或者基于行业要求,某定位辅助信息的时延要求高,则定位服务器可以将该定位辅助信息设置为需要进行周期性广播,或者设置为高优先级。再例如,定位服务器根据终端的定位辅助信息请求,了解到终端对某定位辅助信息需求高,则定位服务器可以将该定位辅助信息设置为需要进行周期性广播,或者设置为高优先级;此外对于一般的定位辅助信息,定位服务器可以将该定位辅助信息设置为需要周期性广播,或者设置为其广播优先级一般或低优先级。
这样,通过在广播方式指示信息中携带上述信息中的至少一种,使得在定位服务器将广播指示消息发送给RAN节点时,RAN节点能够根据广播方式指示信息确定采用何种方式对定位辅助信息进行广播。
进一步地,向无线接入网RAN节点发送广播指示消息时,可以包括如下方式:
针对每个定位辅助信息所对应的系统信息块SIB,向所述RAN节点发送所述广播指示消息;或者,
针对每个定位辅助信息所对应的系统消息SI,向所述RAN节点发送所述广播指示消息;或者,
针对当前需要进行广播的所有定位辅助信息,向所述RAN节点发送所述广播指示消息。
具体的,定位服务器可以针对每个需要广播的定位辅助信息,即每个定位系统信息块(System Information Block)设置广播方式指示信息,并向RAN节点发送携带广播方式指示信息的广播指示消息;还可以针对每个需要广播的定位辅助信息所对应的SI,设置广播方式指示信息,并向RAN节点发送携带广播方式指示信息的广播指示消息;还可以针对当前需要进行广播的所有定位辅助信息,设置广播方式指示信息,并向RAN节点发送携带广播方式指示信息的广播指示消息,实现了定位服务器配置广播指示消息时的多样性。
此外,进一步地,定位服务器在向RAN节点发送广播指示消息之后,还可以接收RAN节点发送的反馈消息,所述反馈消息中携带有定位辅助信息的广播结果信息。
具体的,所述接收所述RAN节点发送的反馈消息时,可以接收每个小区下的定位辅助信息的反馈信息;或者,接收所述RAN节点下的定位辅助信息的反馈信息。
此外,具体的,所述广播结果信息包括下述信息中的至少一种:
进行周期性广播的定位辅助信息的标识信息;
不能进行周期性广播的定位辅助信息的标识信息;
基于终端请求进行广播的定位辅助信息的标识信息;
是否能够按照所述广播方式指示信息进行广播的指示信息;
不能按照所述广播方式指示信息进行广播的定位辅助信息的标识信息;
能够按照所述广播方式指示信息进行广播的定位辅助信息的标识信息;
不能按照所述广播方式指示信息中广播优先级进行广播的指示信息;
不能按照所述广播方式指示信息中广播优先级进行广播的定位辅助信息的标识信息;
能够按照所述广播方式指示信息中广播优先级进行广播的定位辅助信息的标识信息;
所述标识信息为每个定位辅助信息所对应的SIB的标识,或者为每个定位辅助信息所对应的SI的标识。
具体的,由于定位服务器在发送广播指示消息时,可以基于定位辅助信息所对应的SIB发送,也可以基于定位辅助信息所对应的SI发送,因此RAN节点在反馈广播结果信息时,定位辅助信息的标识信息可以为每个定位辅助信息所对应的SIB的标识,或者为每个定位辅助信息所对应的SI的标识,以与定位辅助信息的发送方式相对应。
这样,通过将上述信息中的至少一种作为广播结果信息,使得定位服务器在接收到RAN节点发送的反馈消息时,能够根据反馈消息确定哪些定位辅助信息进行周期性广播,哪些定位辅助信息不能进行周期性广播,哪些定位辅助信息基于终端请求进行广播,是否能够按照广播方式指示信息进行广播,哪些定位辅助信息不能按照广播方式指示信息进行广播,哪些定位辅助信息能够按照广播方式指示信息进行广播,是否能够按照广播方式指示信息中广播优先级进行广播,哪些定位辅助信息不能按照广播优先级进行广播,哪些定位辅助信息能够按照广播优先级进行广播等,从而使得定位服务器能够根据上述反馈信息,确定后续操作,例如如果需要进行周期性广播的定位辅助信息,RAN节点反馈不能提供相关的服务,则定位服务器可以采取其他方式,例如通过用户面定位方式及时提供所需的定位辅助信息。
这样,本实施例通过向RAN节点发送广播指示消息,且广播指示消息中携带有定位辅助信息的广播方式指示信息,使得RAN节点能够基于广播指示消息中的广播方式指示信息,确定采用何种方式对定位辅助信息进行广播,解决了现有技术中无法确定对定位辅助信息采用何种方式进行广播的问题。
此外,如图2所示,为本公开实施例中定位辅助信息的广播方法的步骤流程图之二,该广播方法具体包括如下步骤:
步骤201:接收定位服务器发送的广播指示消息。
在本步骤中,具体的,RAN节点接收定位服务器发送的广播指示消息。其中,该广播指示消息中携带有定位辅助信息的广播方式指示信息。
具体的,广播方式指示信息包括下述信息中的至少一种:是否需要对 所述定位辅助信息进行周期性广播的指示信息;所述定位辅助信息的广播优先级的指示信息;对所述定位辅助信息进行周期性广播的指示信息;基于终端请求对所述定位辅助信息进行广播的指示信息。
在此需要说明的是,上述广播方式指示信息的内容与定位服务器侧广播方式指示信息的内容相同,本实施例中广播方式指示信息的具体内容可以参照上述定位服务器侧对广播方式指示信息的具体说明,在此不再对此进行赘述。
另外,具体的,RAN节点在接收定位服务器发送的广播指示消息时,可以包括如下方式:
接收所述定位服务器针对每个定位辅助信息所对应的系统信息块SIB,发送的广播指示消息;或者,接收所述定位服务器针对每个定位辅助信息所对应的系统消息SI,发送的广播指示消息;或者,接收所述定位服务器针对当前需要进行广播的所有定位辅助信息,发送的广播指示消息。
具体的,RAN节点能够对应接收定位服务器所发送的广播指示消息,实现了RAN节点接收的广播指示消息的多样性。
步骤202:根据广播方式指示信息,确定定位辅助信息的广播方式。
在本步骤中,具体的,RAN节点在接收到广播指示消息之后,可以根据广播方式指示信息,确定定位辅助信息的广播方式。
具体的,在根据广播方式指示信息,确定定位辅助信息的广播方式时,可以根据所述广播方式指示信息,确定所述定位辅助信息的广播方式为进行周期性广播或基于终端请求进行广播。
例如,对于设置为需要进行周期性广播的定位辅助信息,可以采用周期性广播,即一直广播的方式广播该定位辅助信息,未设置为需要周期性广播的定位辅助信息,采用基于终端请求的方式广播对应的定位辅助信息;或者在资源比较紧张的情况下,对设置为需要进行周期性广播的定位辅助信息,可拒绝广播对应的定位辅助信息;或者在资源比较紧张的情况下,对于广播优先级较高的定位辅助信息,采用周期性广播的方式广播该定位辅助信息,优先级较低的定位辅助信息,采用基于终端请求的方式广播该定位辅助信息;或者在资源比较紧张的情况下,对于优先级较高的定位辅助信息,采用周期性广播的方式广播该定位辅助信息,优先级较低的定位辅 助信息,采用基于终端请求的方式广播该定位辅助信息,甚至拒绝广播某定位辅助信息等。
这样,RAN节点根据广播指示消息,并结合自身情况,确定定位辅助信息的广播方式为周期性广播还是基于终端请求进行广播,实现了定位辅助信息的广播方式的确定。
此外,进一步地,RAN节点在根据所述广播方式指示信息,确定所述定位辅助信息的广播方式之后,还可以向所述定位服务器发送反馈信息,所述反馈消息中携带有定位辅助信息的广播结果信息。
具体的,向所述定位服务器发送反馈信息时,可以向所述定位服务器发送每个小区下的定位辅助信息的反馈信息;或者,向所述定位服务器发送RAN节点下的定位辅助信息的反馈信息。
另外,具体的,所述广播结果信息包括下述信息中的至少一种:
进行周期性广播的定位辅助信息的标识信息;
不能进行周期性广播的定位辅助信息的标识信息;
基于终端请求进行广播的定位辅助信息的标识信息;
是否能够按照所述广播方式指示信息进行广播的指示信息;

能够按照所述广播方式指示信息中广播优先级进行广播的定位辅助信息的标识信息;
所述标识信息为每个定位辅助信息所对应的SIB的标识,或者为每个定位辅助信息所对应的SI的标识。
在此需要说明的是,上述广播结果信息的内容与定位服务器侧广播结果信息的内容相同,本实施例中广播结果信息的具体内容可以参照上述定位服务器侧对广播结果信息的具体说明,在此不再对此进行赘述。
下面对定位服务器侧和RAN节点之间的交互过程进行说明。
具体的,定位服务器预先配置定位辅助信息的广播方式指示信息,例如可以基于自身规定的原则,确定需要广播的定位辅助信息是否需要进行周期性广播,或者确定需要广播的定位辅助信息的广播优先级。然后,定位服务器向RAN节点发送广播指示消息,广播指示消息中携带有定位辅助信息的广播方式指示信息,此时RAN节点根据接收到的广播指示消息中的广播方式指示信息,确定定位辅助信息的广播方式,即哪些定位辅助信息可以周期性广播,哪些定位辅助信息采用基于终端请求的方式进行广播。可选地,RAN节点在确定定位辅助信息的广播方式之后,向定位服务器发送反馈信息,以反馈广播结果信息,例如进行周期性广播的定位辅助信息的标识信息、不能进行周期性广播的定位辅助信息的标识信息、基于终端请求进行广播的定位辅助信息的标识信息以及是否能够按照所述广播方式指示信息进行广播的指示信息等,此时定位服务器根据该反馈信息确定定位辅助信息的后续操作过程。
这样,本实施例通过接收定位服务器发送的广播指示消息,广播指示消息中携带有定位辅助信息的广播方式指示信息,然后根据广播方式指示信息,确定定位辅助信息的广播方式,实现了RAN侧对定位辅助信息的广播方式的确定。
此外,具体的,在NR系统中,RAN节点可以进一步分离为中心单元(Central Unit,CU)和分布单元(Distributed Unit,DU),其中底层配置与调度可以由DU生成,RRC消息由CU生成。
在此CU-DUC场景下,如图3所示,为本公开实施例中定位辅助信息的广播方法的步骤流程图之三,该定位辅助信息的广播方法可以包括如下步骤:
步骤301:接收定位服务器发送的广播指示消息。
在本步骤中,具体的,在定位服务器将广播指示消息发送给RAN节点时,RAN节点中的CU可以接收该广播指示消息。
具体的,广播方式指示信息包括下述信息中的至少一种:是否需要对所述定位辅助信息进行周期性广播的指示信息;所述定位辅助信息的广播优先级的指示信息;对所述定位辅助信息进行周期性广播的指示信息;基 于终端请求对所述定位辅助信息进行广播的指示信息。
在此需要说明的是,上述广播方式指示信息的内容与定位服务器侧广播方式指示信息的内容相同,本实施例中广播方式指示信息的具体内容可以参照上述定位服务器侧对广播方式指示信息的具体说明,在此不再对此进行赘述。
另外,具体的,CU在接收定位服务器发送的广播指示消息时,可以包括如下方式:
接收所述定位服务器针对每个定位辅助信息所对应的系统信息块SIB,发送的广播指示消息;或者,接收所述定位服务器针对每个定位辅助信息所对应的系统消息SI,发送的广播指示消息;或者,接收所述定位服务器针对当前需要进行广播的所有定位辅助信息,发送的广播指示消息。
步骤302:将广播指示消息发送至分布单元DU。
在本步骤中,具体的,CU在接收到广播指示消息之后,可以将广播指示消息发送给DU,从而使得DU能够根据该广播指示消息,结合自身情况,确定定位辅助信息的广播方式。
进一步地,CU在将广播指示消息发送至DU之后,还可以接收所述DU发送的反馈消息,所述反馈消息中携带有定位辅助信息的广播结果信息。
具体的,CU在接收所述DU发送的反馈消息之后,还可以将该反馈消息发送至定位服务器,从而使得定位服务器能够根据该反馈消息进行后续操作。
此外,具体的,所述广播结果信息包括下述信息中的至少一种:

在此需要说明的是,上述广播结果信息的内容与定位服务器侧广播结果信息的内容相同,本实施例中广播结果信息的具体内容可以参照上述定位服务器侧对广播结果信息的具体说明,在此不再对此进行赘述。
这样,CU通过将接收到的广播指示消息发送给DU,使得DU能够根据广播指示消息确定定位辅助信息的广播方式,实现了CU-DU场景下,定位辅助信息的广播方式的确定。
此外,如图4所示,为本公开实施例中定位辅助信息的广播方法的步骤流程图之四,包括如下步骤:

具体的,在根据广播方式指示信息,确定定位辅助信息的广播方式时,可以根据所述广播方式指示信息,确定所述定位辅助信息的广播方式为进 行周期性广播或基于终端请求进行广播。
这样,DU根据广播指示消息,并结合自身情况,确定定位辅助信息的广播方式为周期性广播还是基于终端请求进行广播,实现了CU-DU场景下,DU对定位辅助信息的广播方式的确定。
