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。在下面的描述中,提供诸如具体的配置和组件的特定细节仅仅是为了帮助全面理解本公开的实施例。因此,本领域技术人员应该清楚,可以对这里描述的实施例进行各种改变和修改而不脱离本公开的范围和精神。另外,为了清楚和简洁,省略了对已知功能和构造的描述。
应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与 实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中,应理解,下述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本公开实施例的实施过程构成任何限定。
本公开实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
在进行本公开实施例的说明时,首先对下面描述中所用到的一些概念进行解释说明。
一、IAB架构
IAB架构如图1所示,IAB锚点包括一个IAB donor CU和一个或多个IAB donor DU(s),IAB节点通过NR Uu接口的UE功能连接上游IAB节点或IAB donor DU。IAB节点通过NR Uu接口的网络功能为下游IAB节点和UEs提供无线回传。
二、可移动网络节点
可移动网络节点例如VMR,如图2和图3所示,在使用卫星接入作为回传链路的车载中继的场景中,可以使用IAB架构,卫星和地面分别作为IAB donor的DU和CU,车载中继可以作为IAB node,如图4所示。由于卫星覆盖面积较大,通常会覆盖多个TA,在卫星通信中卫星广播它所覆盖的所有TA,终端从中选择一个TA接入。其中,IAB donor CU可以与接入和移动管理功能(Access and Mobility Management Function,AMF)、用户面功能(User Plane Function,UPF)、会话管理功能(Session Management Function,SMF)等网络节点连接。
三、系统信息块1(System Information Block 1,SIB1)广播消息
跟踪区域标识(Tracking Area Identity,TAI):SIB1携带的小区接入相关信息(CellAccessRelatedInfo)中包含移动国家码(Mobile Country Code,MCC)、移动网络码(Mobile Network Code,MNC)、TAC,其中,TAI=MCC+MNC+TAC。
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,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做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。
本公开的实施例提供了一种广播参数配置方法及装置,用以解决相关技术中的广播TAC的方法不适用于可移动网络节点的通信场景的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图5所示,本公开的实施例提供了一种广播参数配置方法,应用于第一网络设备,所述方法具体包括以下步骤:
步骤501、第一网络设备获取第一跟踪区域TA映射区域的信息,第一TA映射区域包括至少一个TA;
步骤502、所述第一网络设备根据广播覆盖区域的中心点位置,从所述第一TA映射区域中确定所述中心点位置所在的目标TA;
步骤503、所述第一网络设备发送广播消息,所述广播消息包括所述目标TA对应的跟踪区域码TAC。
该实施例中,所述第一网络设备是可移动的网络设备,如车载中继。在IAB架构中,所述第一网络节点作为IAB node。
所述第一TA映射区域是与所述第一网络设备的当前位置相对应的TA映射区域,该第一TA映射区域内包含一个或者多个TA,其中包括所述第一网络设备的广播覆盖区域的中心点位置所在的TA。所述第一网络设备支持定位服务,通过自身定位确定广播覆盖区域的中心点,在所述第一TA映射区域中查找该中心点所在的目标TA,并广播该目标TA的TAC。
其中,所述第一TA映射区域是由第二网络设备将一定地理区域的TA进行划分获得的。所述第二网络设备对一定区域的TA进行划分可以获得多个TA映射区域,每个TA映射区域包括至少一个完整的TA,划分获得的TA映 射区域还可以称为TA映射表区域(TA mapping List Area)。
以所述第二网络设备划分获得两个TA映射区域为例,如图6所示,其中TA mapping List 1 Area包括TA1、TA2、TA3、TA4;TA mapping List 2 Area包括TA5、TA6、TA7。所述第一网络设备(即IAB node)当前位于TA mapping List 1 Area中的TA4,则TA mapping List 1 Area是所述第一TA映射区域,所述第一网络设备的广播覆盖区域的中心点位于TA4,即所述TA4是所述目标TA,所述第一网络设备广播TA4。
本公开的实施例,第一网络设备根据广播覆盖区域的中心点位置,在第一TA映射区域中查找中心点所在的目标TA,并广播该目标TA对应的TAC。由于第一网络设备广播的TAC是根据广播覆盖区域的中心点位置确定的,其可以随着所述第一网络设备的位置变化而变化,能够保证广播的TAC的准确性。
作为一个可选实施例,所述获取第一TA映射区域的信息,包括:
(1)接收第二网络设备发送的至少一个TA映射区域的信息,所述至少一个TA映射区域包括所述第一TA映射区域;
或者,
(2)向第二网络设备发送第一请求消息,所述第一请求消息包括所述第一网络设备的移动信息;接收所述第二网络设备发送的第一TA映射区域的信息,所述第一TA映射区域是根据所述第一网络设备的移动信息确定的。
该实施例中,所述第一TA映射区域的信息可以是所述第二网络设备下发的,即所述第二网络设备可以向第一网络设备发送多个TA映射区域的信息,第一网络设备可以根据自身位置确定对应的第一TA映射区域。例如:第二网络设备共划分3个TA映射区域,可以将3个TA映射区域的信息均发送到所述第一网络设备,所述第一网络设备可以根据自身定位确定当前处于第一TA映射区域,并从该第一TA映射区域中查找目标TA。
所述第一TA映射区域的信息也可以是所述第一网络设备向所述第二网络设备请求的,即所述第一网络设备向所述第二网络设备发送请求消息,该请求消息携带所述第一网络设备的移动信息,该移动信息用于第二网络设备分配对应的第一TA映射区域;所述第二网络设备可以根据所述第一网络设 备的移动信息匹配对应的第一TA映射区域,并将第一TA映射区域的信息发送给所述第一网络设备,所述第一网络设备从该第一TA映射区域中查找目标TA。
可选地,所述向第二网络设备发送第一请求消息之前,所述方法还包括:进行移动信息测量,获取移动信息;
所述向第二网络设备发送第一请求消息,包括:在确定未存储与所述移动信息匹配的第一TA映射区域的情况下,向所述第二网络设备发送第一请求消息。
可选地,所述移动信息包括以下至少一项:
1)地理位置信息;
2)移动方向信息;
3)移动速度信息;可以是移动速度的范围区域标识。
该实施例中,第一网络设备在发送广播消息之前,进行定位测量获得自身当前的地理位置、移动方向、移动速度等一项或者多项信息,根据获得的移动信息,确定是否存储有该移动信息对应的TA映射区域的信息(即所述第一TA映射区域的信息),若未存储当前位置相应的TA映射区域的信息,则向第二网络设备发送第一请求消息,该第一请求消息中携带测量获得的移动信息,该移动信息用于请求第二网络设备配置第一TA映射区域的信息。
如果所述第一网络设备确定存储有当前移动信息对应的第一TA映射区域的信息,则根据广播覆盖区域的中心点位置在该第一TA映射区域中查找需要广播的TAC。
作为一个可选实施例,所述方法还包括:进行移动信息测量,获取移动信息;在根据所述移动信息确定所述第一网络设备与所述第一TA映射区域的边界距离小于第一阈值的情况下,向所述第一网络设备发送第二请求消息,所述第二请求消息包括所述移动信息。
该实施例中,由于所述第一网络设备是可移动的,其广播覆盖区域的中心点位置是可变化的,该第一网络设备可以以预定周期进行移动信息测量,获得实时的移动信息,在第一网络设备根据移动信息判断到距离第一TA映射区域的边界较近(即距离小于第一阈值,第一阈值可以根据终端的移动速 度等参数设置)时,认为在较快时间内第一网络设备可能移动到第一TA映射区域的范围之外,为了保证广播的TAC的准确性,第一网络设备向第二网络设备发送第二请求消息,其中携带第一网络设备实时获得的移动信息,该第二请求消息用于请求更新TA映射区域的信息。
可选地,所述方法还包括:接收第二网络设备发送的第二TA映射区域的信息,所述第二TA映射区域根据所述移动信息确定的,所述第二TA映射区域与所述第一TA映射区域至少部分不重叠。
该实施例中,所述第二网络设备接收第一网络设备发送的第一请求消息后,根据其中携带的移动信息判断是否需要为该第一网络设备重新分配TA映射区域,如果需要,则将根据该移动信息确定的第二TA映射区域的信息发送给第一网络设备,则第一网络设备可以在发送广播消息之前,根据更新的广播覆盖区域的中心点位置,在该第二TA映射区域中查找对应的TA,并广播TAC。
所述第一网络设备重新请求的第二TA映射区域,与第一网络设备此次上报的地理位置、移动速度、移动方向中的一项或者多项有关。
需要说明的是,所述第二TA映射区域可以与第一TA映射区域存在部分重叠,也可以完全不重叠。如图7所示,TA mapping List 1Area包括:TA1、TA2、TA3、TA4和TA7。TA mapping List 2 Area包括:TA4、TA7、TA5、TA6、TA8和TA9,其TA4、TA7是重叠区域。
所述第二网络设备在划分TA映射区域时,可以根据第一网络设备上报的移动信息划分,也可以根据预定规则划分。例如:TA映射区域的划分与TA的划分有关,一个TA映射区域内包含的TA均是完整的TA;TA映射区域的划分与IAB node的移动速度有关,如移动速度快的IAB node,分配的地理区域更大;TA映射区域的划分还可以和IAB node的移动方向有关,例如IAB-node被分配的TA映射区域需包含当前移动方向上的M个完整TA。
下面举例说明第二网络节点划分TA映射区域以及第一网络节点从TA映射区域中查找对应的目标TA的实现过程。
作为一个可选实施例,以第二网络设备是操作维护管理(Operation Administration and Maintenance,OAM)节点为例,如图8所示,包括:
(1)OAM具有所有地理位置区域与TAC的对应表格(即具有划分好的TA映射区域信息)。OAM可以预先进行TA映射区域划分,每个TA映射区域覆盖多个TA。
可选地,OAM划分TA映射区域时,可以预先划分为多种颗粒度的TA映射区域,例如:根据移动速度划分、根据移动方向划分、根据地理位置划分、根据预定的TA映射区域包含的TA数量划分等等。
根据移动速度划分TA映射区域例如:OAM首先将移动速度进行档位划分([0,V1]、[V1,V2]、[V2,V3]……)。OAM为低速度档位的IAB node配置的TA映射区域的覆盖区域较小,为高速度档位的IAB node配置的TA映射区域的覆盖区域较大,例如:IAB node1和IAB node2位于同一位置,IAB node1的移动速度为IAB node2的移动速度的2倍,OAM分别为IAB node1和IAB node2配置TA Mapping List p Area和TA Mapping List q Area,其中TA Mapping List q Area是TA Mapping List p Area的子集。
根据移动方向划分TA映射区域例如:以IAB node的地理位置为起点,针对每个移动方向,将移动方向上的预定数量的TA划分为1个TA映射区域。
根据地理位置划分TA映射区域例如:将地理位置周围预定数量的TA划分为1个TA映射区域。
根据预定的TA映射区域包含的TA数量划分TA映射区域例如:设置各个TA映射区域均包含N个TA。
需要说明的是,OAM还可以参考上述移动速度、移动方向、地理位置中的多项的组合,划分TA映射区域,具体划分方式不做赘述。
(2)IAB node向OAM上报自身的地理位置和速度范围区间标识,每个标识对应一个速度范围。
OAM根据IAB node初始注册过程上报的地理区域和速度标识,分配TA映射区域,即该实施例中的TA映射区域是根据地理位置和移动速度划分的。TA映射区域可能覆盖多个TA。
若IAB node不支持速度标识上报,第二网络设备无法获取IAB node的移动速度时,按照预定规则为此类IAB node配置TA映射区域,例如:按照预定的TA数量配置TA映射区域。
(3)IAB node在发送广播消息前,定位自己当前位置,查看是否具有当前位置对应的TA映射区域的信息。
(4)若没有当前位置对应的TA映射区域的信息,则IAB node向OAM请求TA映射区域的信息,请求消息中可以携带IAB node的当前地理位置和IAB node的速度标识。
(5)IAB node定位自己当前位置,根据广播覆盖区域的中心点广播TAC。
可选地,如果IAB node存储有当前位置对应的TA映射区域的信息,则在该TA映射区域中查找广播覆盖区域的中心点位置所在的TAC。
(6)当IAB node根据定位判断当前所在的位置距离TA映射区域的边界小于阈值S时,IAB node向OAM请求更新TA映射区域,请求消息中可以携带IAB-node当前地理位置和IAB node的速度标识。
需要说明的是:该请求消息还可以携带IAB-node移动方向,便于OAM精确划分TA映射区域,若IAB node未上报移动方向,则后续OAM下发的更新后的TA映射区域与之前下发的TA映射区域可能存在重叠的TA。
(7)IAB node根据定位判断当前广播覆盖区域的中心点是否仍在当前广播的TA,若是,则在广播消息中仍携带之前广播的TAC;若不是,则重复执行步骤(3)。
作为另一个可选实施例,以第二网络设备是网络功能实体(Network Function,NF)节点为例,所述NF可以是IAB donor、接入和移动管理功能(Access and Mobility Management Function,AMF)等。
该实施例中,在NF为IAB node配置TA映射区域时,携带一定区域的地理位置(即TA地理位置范围)和TA的映射关系。
在IAB node的初始注册过程中,向NF上报该IAB node的地理位置、移动速度的标识和移动方向。TA映射区域可以是根据IAB node的移动速度、地理位置和移动方向划分的,例如:IAB node处于低速度档位,该低速度档位可以被分配N个TA,则为该IAB node划分的TA映射区域是以地理位置为起点,朝向移动方向延伸N个TA的区域。
假设NF是AMF,IAB node的地理位置、移动速度以及移动方向由IAB node经IAB donor报给AMF,其他NF可以向AMF订阅上述信息。该实施 例中,可以由IAB node在发送广播消息前向AMF请求该TA映射区域。
本公开的实施例,解决了IAB node随机移动,卫星作为IAB donor覆盖多个TA,网络无法根据移动基站的位置广播TAC的问题。
本公开的实施例,第一网络设备根据广播覆盖区域的中心点位置,在第一TA映射区域中查找中心点所在的目标TA,并广播该目标TA对应的TAC。由于第一网络设备广播的TAC是根据广播覆盖区域的中心点位置确定的,其可以随着所述第一网络设备的位置变化而变化,能够保证广播的TAC的准确性。
如图9所示,本公开实施例还提供一种广播参数配置方法,应用于第二网络设备,所述方法包括:
步骤901、第二网络设备向第一网络设备发送第一TA映射区域的信息,所述第一TA映射区域包括至少一个TA。
该实施例中,所述第二网络设备可以是OAM、AMF、IAB-donor等网络节点。所述第一网络设备是可移动的网络设备,如车载中继。在IAB架构中,所述第一网络节点作为IAB node。
所述第一TA映射区域是与所述第一网络设备的当前位置相对应的TA映射区域,该第一TA映射区域内包含一个或者多个TA,其中包括所述第一网络设备的广播覆盖区域的中心点位置所在的TA。所述第一网络设备支持定位服务,通过自身定位确定广播覆盖区域的中心点,在所述第一TA映射区域中查找该中心点所在的目标TA,并广播该目标TA的TAC。
所述第一TA映射区域是由所述第二网络设备将一定地理区域的TA进行划分获得的。所述第二网络设备对一定区域的TA进行划分可以获得多个TA映射区域,每个TA映射区域包括至少一个完整的TA。
本公开的实施例,第二网络设备向第一网络设备发送第一网络设备当前位置所在的第一TA映射区域的信息,使所述第一网络设备可以在该第一TA映射区域中查找广播覆盖区域的中心点所在的目标TA,并广播该目标TA对应的TAC。由于第一TA映射区域是与第一网络设备当前位置对应的,第一网络设备广播的TAC是根据广播覆盖区域的中心点位置确定的,其可以随着所述第一网络设备的位置变化而变化,能够保证广播的TAC的准确性。
作为一个可选实施例,所述向第一网络设备发送第一TA映射区域的信息,包括:
(1)向所述第一网络设备发送至少一个TA映射区域的信息,所述至少一个TA映射区域包括所述第一TA映射区域;
或者,
(2)接收所述第一网络设备发送的第一请求消息,所述第一请求消息包括所述第一网络设备的移动信息;确定与所述第一网络设备的移动信息匹配的第一TA映射区域,并向所述第一网络设备发送所述第一TA映射区域的信息。
可选地,所述移动信息包括以下至少一项:
地理位置信息;
移动方向信息;
移动速度信息。
该实施例中,所述第一TA映射区域的信息可以是所述第二网络设备下发的,即所述第二网络设备可以向第一网络设备发送多个TA映射区域的信息,第一网络设备可以根据自身位置确定对应的第一TA映射区域。所述第一TA映射区域的信息也可以根据第一网络设备的请求消息下发的,该请求消息携带所述第一网络设备的移动信息,该移动信息用于第二网络设备分配对应的第一TA映射区域;所述第二网络设备可以根据所述第一网络设备的移动信息匹配对应的第一TA映射区域,并将第一TA映射区域的信息发送给所述第一网络设备,所述第一网络设备从该第一TA映射区域中查找目标TA。
可选地,所述方法还包括:
接收第一网络设备发送的第二请求消息,所述第二请求消息包括所述第一网络设备的移动信息;
在根据所述移动信息确定所述第一网络设备与所述第一TA映射区域的边界距离小于第一阈值的情况下,确定与所述移动信息匹配的第二TA映射区域;
向所述第一网络设备发送所述第二TA映射区域的信息,所述第二TA映射区域与所述第一TA映射区域至少部分不重叠。
该实施例中,由于所述第一网络设备是可移动的,其广播覆盖区域的中心点位置是可变化的,第一网络设备可以以预定周期进行移动信息测量,获得实时的移动信息,在第一网络设备根据移动信息判断到距离第一TA映射区域的边界较近时,认为在较快时间内第一网络设备可能移动到第一TA映射区域的范围之外,为了保证广播的TAC的准确性,第一网络设备向第二网络设备发送第二请求消息,其中携带第一网络设备实时获得的移动信息,该第二请求消息用于请求更新TA映射区域的信息。
所述第二网络设备接收到所述第二请求消息后,根据所述第二请求消息携带的移动信息判断第一网络设备的当前位置,在确定第一网络设备距离之前配置的第一TA映射区域的边界较近时,为第一网络设备分配并发送第二TA映射区域,使第一网络设备可以在发送广播消息之前,可以根据更新的广播覆盖区域的中心点位置,在该第二TA映射区域中查找对应的TA,并广播TAC。
作为一个可选实施例,所述向第一网络设备发送第一TA映射区域的信息之前,所述方法还包括:
划分TA映射区域,每个所述TA映射区域包括至少一个TA。
可选地,所述划分TA映射区域,包括以下至少一项:
(1)根据第一网络设备的初始注册过程中上报的移动信息,划分TA映射区域;
(2)根据预定的TA映射区域包含的TA数量,划分TA映射区域。
该实施例中,所述第二网络设备在划分TA映射区域时,可以根据第一网络设备上报的移动信息划分,也可以根据预定规则划分。例如:TA映射区域的划分与TA的划分有关,一个TA映射区域内包含的TA均是完整的TA;TA映射区域的划分与IAB node的移动速度有关,如移动速度快的IAB node,分配的地理区域更大;TA映射区域的划分还可以和IAB node的移动方向有关,例如IAB node被分配的TA映射区域需包含当前移动方向上的M个完整TA。
可选地,第二网络设备在划分TA映射区域时,可以预先划分为多种颗粒度的TA映射区域,例如:根据移动速度划分、根据移动方向划分、根据 地理位置划分、根据预定的TA映射区域包含的TA数量划分等等。
其中,根据移动方向划分TA映射区域例如:以第一网络设备的地理位置为起点,针对每个移动方向,将移动方向上的预定数量的TA划分为1个TA映射区域。
根据地理位置划分TA映射区域例如:将地理位置周围预定数量的TA划分为1个TA映射区域。
根据预定的TA映射区域包含的TA数量划分TA映射区域例如:设置各个TA映射区域均包含N个TA。
作为一个可选实施例,所述根据第一网络设备的初始注册过程中上报的移动信息,划分TA映射区域,包括:
将移动速度进行档位划分;确定所述第一网络设备的移动速度归属的速度档位;根据所述速度档位,确定所述第一网络设备对应的TA映射区域;其中,高速度档位对应的TA映射区域的覆盖范围,大于低速度档位对应的TA映射区域的覆盖范围。
该实施例中,在第二网络设备接收到第一网络设备上报的移动信息后,确定第一网络设备所属的速度档位,根据速度档位分配相应的TA映射区域。
第二网络设备可以首先将移动速度进行档位划分([0,V1]、[V1,V2]、[V2,V3]……)。第二网络设备为低速度档位的IAB node配置的TA映射区域的覆盖区域较小,为高速度档位的IAB node配置的TA映射区域的覆盖区域较大,例如:IAB node1和IAB node2位于同一位置,IAB node1的移动速度为IAB node2的移动速度的2倍,则第二网络设备分别为IAB node1和IAB node2配置TA Mapping List p Area和TA Mapping List q Area,其中TA Mapping List q Area是TA Mapping List p Area的子集。
本公开的实施例,第二网络设备可以根据第一网络设备的移动信息划分TA映射区域,并将TA映射区域发送给第一网络设备,使所述第一网络设备可以在该第一TA映射区域中查找广播覆盖区域的中心点所在的目标TA,并广播该目标TA对应的TAC。由于第一网络设备接收到的TA映射区域是与当前位置对应的,第一网络设备广播的TAC是根据广播覆盖区域的中心点位置确定的,其可以随着所述第一网络设备的位置变化而变化,能够保证广播的 TAC的准确性。
