一种小区全局标识的配置方法、装置及存储介质
相关申请的交叉引用
本申请要求在2020年07月13日提交中国专利局、申请号为202010671483.3、申请名称为“一种小区全局标识的配置方法、装置及存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及移动通信领域,尤其是涉及一种小区全局标识的配置方法、装置及存储介质。
背景技术
在移动通信领域中,传统移动通信基站通常固定于地面,而还有一些非固定于地面的移动通信基站(如固定在卫星、飞机、火车等上的基站),在一些场景(如海洋通信、偏远地区通信等)中往往能发挥更大的作用。
为了尽量降低基站的移动性对通信核心网的影响,业界提出可以复用新空口技术之中既有的“分离式gNB”设计,即将一个无线接入网逻辑节点gNB分为一个中心单元(Central Unit,CU)与多个分布单元(Distributed Unit,DU)两部分,其中DU的功能类似于基站,直接控制无线小区。在需要部署非地面固定基站的场景中,将DU部署于卫星、列车、飞机等移动载具上,而将CU部署于地面上。
在现有技术中,小区的全局标识(Cell Global Identifier,CGI)由网管直接配置并告知DU,出于路由等目的,该CGI的若干个最高位必须严格等于其所属的gNB的全球唯一标识。但对于存在移动性的DU来说,需要时常在不同的CU之间迁移。由于CU与gNB一一对应,这同时意味着DU所属的gNB时常会变化,这就使得网管不得不经常为移动的DU配置CGI,这个配置过程操作复杂且容易导致诸如CGI分配冲突等错误。
鉴于此,如何快捷、准确的为移动的DU配置全局标识,成为一个亟待解决的技术问题。

具体实施方式
本申请实施列提供一种小区全局标识的配置方法、装置及存储介质,以解决现有技术中存在的为移动的DU配置全局标识操作复杂且易出错的技术 问题。
本申请实施例中的技术方案为解决上述的技术问题,总体思路如下:
提供一种小区全局标识的配置方法,应用于目标CU,该配置方法包括:为DU所辖小区配置第一全局标识;其中,第一全局标识为DU迁移到目标CU后,小区使用的全局标识;向DU发送第一全局标识。
由于在上述方案中,通过目标CU为即将迁入的DU配置第一全局标识,并发送给DU,使得目标CU可以在DU迁入目标CU时动态的为DU所辖的小区分配第一全局标识,从而让DU在不同CU间进行迁移时无需网管的介入,也就不需要网管使用复杂的信令流程在DU每次迁移时为DU所辖的小区配置全局标识,从而能够快捷、准确的为移动的DU配置全局标识。
为了更好的理解上述技术方案,下面通过附图以及具体实施例对本申请技术方案做详细的说明,应当理解本申请实施例以及实施例中的具体特征是对本申请技术方案的详细的说明,而不是对本申请技术方案的限定,在不冲突的情况下,本申请实施例以及实施例中的技术特征可以相互组合。
在介绍本申请的技术方案前,先介绍与本申请相关的技术知识:
1)小区标识
在一个无线通信网络之中,每一个无线通信小区(Cell)均有一个适用于该接入技术(Radio Access Technology,RAT)的全球唯一的标识,即小区全局标识(Cell Global Identifier,CGI)。
以新空口(New Radio,NR)这种RAT为例,NR的CGI即为NCGI(NR CGI)。NCGI是一个长度为60比特的比特串,其最高n位严格等于(其中n的取值范围为46≤n≤56的整数):
①该小区所属的无线接入网节点(gNB,非缩写,其含义为属于5G系统并且使用NR技术提供无线接入服务的无线接入网节点)的全局gNB标识(Global gNB Identifier,Global gNB ID)。或者,
②该小区所属的无线接入网节点(en-gNB,非缩写,其含义为属于演进的分组系统(Evolved Packet System,EPS)并且使用NR技术提供无线接入 服务的无线接入网节点)的全局en-gNB标识(Global en-gNB Identifier,Global en-gNB ID)。
这一设计主要是为了方便路由功能:只要一个无线接入网节点了解到一个小区的NCGI,它就可以根据其若干最高位逐步路由到该小区所述的gNB或en-gNB。路由的便利性对于诸如切换、空口干扰消除、自动邻区关系建立等诸多功能都是至关重要的。
2)gNB-CU/DU分离
为了适应多样化的部署场景,业界提出了gNB-CU/DU分离技术。该技术将一个gNB或en-gNB进一步细分为一个CU与一个或多个DU。二者之间以F1接口相连。按照当前技术,一个DU在同一时刻只能连接一个CU。
请参见图1为gNB-CU/DU分离的结构示意图,实线代表数据通道,包括承载与节点间信令。
其中,gNB-CU包含控制着整个gNB或en-gNB的中心控制功能、空口无线资源控制(Radio Resource Control,RRC)功能、接口RRC功能、服务数据适配协议(Service Data Adaptation Protocol,SDAP)功能以及分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)功能,而gNB-DU包含接口RRC功能、无线链路控制(Radio Link Control,RLC)功能、媒体介入控制(Media Access Control,MAC)功能、物理(Physical,PHY)功能以及射频(Radio Frequency,RF)功能等。针对具体小区的控制属于物理功能,进而属于gNB-DU功能之一。
在gNB-CU/DU架构下,gNB-DU所控制的小区的NCGI直接由网管直接配置。具体地,在网络部署过程中,在gNB-DU启用之前,网管会告知该gNB-DU其应当与哪一个gNB-CU相连接,以及其所控制的所有小区具体配置,其中包括这些小区的NCGI的具体取值。此后gNB-DU会按照网管的配置与网管所指定的gNB-CU相连接并建立F1接口,然后通过F1接口将包含下辖小区NCGI在内的自身的配置信息告知gNB-CU。在DU固定部署于地面时,通常来说在此之后NCGI会一直保持不变。
由于一个gNB或en-gNB之中只能包含一个gNB-CU,Global gNB ID或者Global en-gNB ID通常也会被等价地视为该gNB-CU的全局标识。
然而,实际部署中可能存在着一个gNB-DU需要时常在多个gNB-CU之间迁移的情况。
例如,为了为处于地广人稀的偏远地区(或者处于大洋上)的设备提供无线接入服务,gNB-DU可以位于近地轨道卫星上,而近地轨道卫星相对于地面都是并非静止不动的。又例如,由于波段穿透力等诸多因素的限制,列车、飞机等大型交通工具上的终端如果与固定于地面的传统移动通信基站直接连接,频谱利用效率往往较低,不利于宽带传输。在这种情况下,如果将gNB-DU部署于这些大型交通工具内部,服务质量能够得到显著提升。相对地,gNB-CU则与既有的地面系统类似,部署于固定于地面的位置,例如机房之中。
由于这类gNB-DU通常处于运动之中,实际运作中很难保证一个gNB-DU能够永远仅与一个gNB-CU相连接。这也就意味着gNB-DU需要在不同的gNB-CU之间迁移,亦即,断开与旧gNB-CU的连接,并且与新gNB-CU连接。由于CGI的高比特位严格等于Global gNB ID或Global en-gNB ID,在gNB-DU的迁移过程中CGI也需要变化。如果每次gNB-DU迁移都需要网管介入,信令流程将十分复杂而低效,且很容易导致错误。
需要说明的是,当DU是移动的时,DU与CU之间的通信接口也称之为F1接口,该F1接口的建立可以通过有线传输,比如网线、光纤,还可以通过无线传输,比如DU的特定UE与目标CU之间的RRC连接;DU与目标CU之间的激光链路;DU与目标CU之间的微波链路。其中,DU的特定UE为具备与目标CU之间存在RRC连接的UE,比如集成接入和回程(Integrated Access and Backhaul,IAB)网络中的移动终端(mobile terminal,MT)。
比如,移动的DU处连接一个特定UE(移动DU和特定UE部署在一起,比如在同一个物理设备上,或通过有线连接临近部署);每个CU连接一个特定DU(CU和特定DU可以部署在一起,比如在同一个物理设备上,或在不 同的两个物理设备上,通过有线连接临近部署)。
特定UE可以驻留在与CU连接的特定DU上,对移动的DU信号进行测量和上报;UE和CU之间的RRC连接可以作为该移动的DU和CU之间的F1接口的承载。
在DU移动的场景下,与DU的特定UE可以先切换到目标CU下,然后在特定UE和目标CU之间的RRC连接上来承载DU和目标CU之间的F1建立和后续的F1信令。
又如,移动的DU部署在火车上时,移动的DU使用F1接口传输信息,可以在火车到达站点,利用站点的有线网络承载F1接口进行信息传输及切换到目标CU。
为了解决上述问题,本申请采用了以下解决方案:
请参考图2,本申请实施例提供一种小区全局标识的配置方法,应用于目标CU,该配置方法的处理过程如下。
步骤201:为DU所辖小区配置第一全局标识;其中,第一全局标识为DU迁移到目标CU后,小区使用的全局标识。
步骤202:向DU发送第一全局标识。
在DU迁入目标CU前,假设DU是与源CU连接(指传输层的信道和协议层都是连通)的,某个时刻源CU决定将DU迁移到目标CU,于是源CU向目标CU发送迁移请求,目标CU接收到源CU发送的迁移请求后,决定接纳迁移请求,便为DU所辖小区配置第一全局标识,并发送给DU,以便DU迁入目标CU后,DU所辖小区能使用第一全局标识。
目标CU向DU发送第一全局标识,可以是由目标CU直接发送给DU,也可以是目标CU经源CU间接发送给DU。
若目标CU与DU之间建立了连接(指建立了传输层的信道),目标CU可以直接将第一全局标识发送给DU:
目标CU发送第一接口消息给DU,其中,第一接口消息中包括第一全局标识。
第一接口消息还包括第一全局标识与第二全局标识的对应关系;其中,第二全局标识为DU在迁移到所述目标CU前,小区使用的全局标识。
请参见图3为本申请实施例提供的源CU通过F1触发迁移的流程图一。
步骤301:目标CU接收源CU发送的迁移请求,该迁移请求用于请求将DU迁移到目标CU。
步骤302:目标CU向源CU发送迁移响应,该迁移响应用于确定接受DU的迁移。
步骤303:源CU向DU发送迁移指示,指示DU迁移到目标CU。
步骤304:目标CU与DU连接。
同时,源CU释放DU所占用的第二全局标识。
之后,DU将所辖小区的系统信息广播之中的第二全局标识变更为第一全局标识。
步骤305:目标CU接收DU发送的第四接口消息,该第四接口消息中包括DU所辖小区的第二全局标识。
第二全局标识为DU与源CU连接时,DU所辖小区使用的全局标识。第四接口消息用于建立DU与目标CU之间的F1逻辑接口。
步骤306:目标CU为DU所辖小区配置第一全局标识。
第一全局标识为DU与目标CU连接时,DU所辖小区使用的全局标识。
