本申请基于申请号为201710061512.2、申请日为2017年01月26日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
本发明涉及无线通信领域,尤其涉及一种实现测量协调的方法、系统和用户设备(User Equipment,UE)和计算机存储介质。
为实现高效、可靠的无线资源管理(Radio Resource Management,RRM),在第四代(the fourth Generation,4G)通信系统中,使用长期演进(Long Term Evolution,LTE)无线接入技术(Radio Access Technology,RAT)的演进型基站(E-UTRAN NodeB,eNB)会为用户设备(User Equipment,UE)提供测量配置,其中,所述测量配置包括如下参数:
·测量目标(Measurement objects):对E-UTRAN而言,该参数是一个E-UTRAN载波频率,UE根据所述参数执行同频或异频测量;
·上报配置(Reporting configurations):该参数定义了触发E-UTRAN测量上报事件的标准,具体的,包括上报标准与上报形式;进一步的,触发测量上报(Measurement report triggering)会基于多种事件,比如Event A1,A1事件即表示服务小区的信号质量高于一定门限;
·测量标识(Measurement identities):该参数联结了测量目标与上报配置两个参数,使得两者之间能够形成一对多、或多对一的联结关
系;
·数量配置(Quantity configurations):每个RAT类型会配置一个数量配置,该参数定义了测量数量与相应的滤波参数;
·测量间隔(Measurement gaps):该参数定义了UE执行测量的时间,在测量间隔内,网络侧不会调度UE进行上下行数据的传输。
UE根据所述测量配置执行测量及上报操作。进一步的,在进行测量时还会区分各小区的类型,如服务小区、列表小区以及检测小区,其中,如果UE配置为支持载波聚合(Carrier Aggregation,CA),那么CA中的主服务小区(Primary Cell,PCell)与辅服务小区(Secondary Cell,SCell)都算为UE执行测量时的服务小区(Serving cell);但是,只有主服务小区PCell的频点才是UE测量时的主频(Primary Frequency)。另外,因为PCell作为UE的主服务小区,会对UE的无线资源配置与移动性管理等行为负责,所以在测量时会有其专用的测量配置参数(如质量门限s-Measure),而上述的测量上报触发也会包含针对PCell的专用事件(如Event A5,表示PCell的信号质量低于一定门限、而邻区信号的质量较好),且在上报时也会将其测量结果专门写入某些参数(如measResultPCell)中。也就是说,在进行测量时,主服务小区、或者说测量时的主频,有其特殊的测量配置与测量上报方法。
目前,业界已开始了对第五代(the fifth Generation,5G)通信系统的研究。不同于4G无线接入网(Radio Access Network,RAN)中使用LTE RAT、并接入演进分组核心网(Evolved Packet Core,EPC)的eNB,通常我们称5G RAN中使用新型无线(New Radio,NR)技术、并接入下一代核心网(Next generation Core,NGC)的基站为下一代基站(generation NodeB,gNB)。
为了充分利用业已大规模部署的LTE eNB、并使得LTE RAT能够平滑的过渡到NR RAT,业界提出了一种配置两个RAT以紧耦合的方式来为UE提供通信服务的系统,称为LTE-NR紧耦合(tight Interworking),其架构可参考
图1至图3的示例;图1为LTE-NR tight Interworking架构的第一个示例的结构图,如图1所示,LTE eNB和NR gNB为两个基站,LTE eNB和NR gNB分别与EPC形成通信连接,LTE eNB与EPC间不仅建立用户面(User Plane,UP)接口、也建立控制面(Control Plane,CP)接口,对于图1,将LTE eNB称为主基站(Master eNB,MeNB);NR gNB与LTE eNB间可以建立CP接口和UP接口(NR gNB与LTE eNB间的接口可称为Xx接口),可选的,NR gNB还可以与EPC建立UP接口,对于图1,将NR gNB称为辅基站(Secondary gNB,SgNB)。
图2为LTE-NR tight Interworking架构的第二个示例的结构图,图2的结构与图1基本相同,其区别点在于,用NGC代替了图1中的EPC。
图3为LTE-NR tight Interworking架构的第三个示例的结构图,如图3所示,LTE eNB和NR gNB为两个基站,LTE eNB和NR gNB分别与NGC形成通信连接,NR gNB与NGC间不仅建立UP接口、也建立CP接口,对于图3,将NR gNB称为主基站;LTE eNB与NR gNB间可以建立CP接口和UP接口(LTE eNB与NR gNB间的接口可称为Xx接口),可选的,LTE eNB还可以与NGC建立UP接口,对于图3,将LTE eNB称为辅基站。
对于图1至图3的三种LTE-NR tight Interworking架构,主基站和辅基站均可以对UE进行CA配置,其中,在辅基站侧,UE的主服务小区可以称为辅主小区(Primary Secondary Cell,PSCell)。
LTE-NR tight Interworking架构的典型特点是UE的两个服务基站(主基站和辅基站)使用不同的RAT,所以主基站难以负责全面、充分的无线资源管理,这里,主基站可以至少负责自身一侧的无线资源配置(如可包括无线协议栈的配置、一定范围内的移动调度等)、并能够生成相应的无线资源控制(Radio Resource Control,RRC)协议数据单元(Protocol Data Unit,PDU);以测量配置为例,主基站和辅基站可以分别对UE进行测量配置,UE基于
主基站和辅基站的测量配置进行对应小区的测量,并将测量结果至少上报给主网元。在现有技术中,可能存在这样的情况,主基站在接收到UE的测量上报之后,在UE与辅网元的特定基站上的通信信道足够好的情况下,也控制UE断开与该辅网元的连接,从而导致辅网元的错误释放。
发明内容
为解决现有存在的技术问题,本发明实施例提供一种实现测量协调的方法、系统、UE和计算机存储介质,可以对至少两个基站的测量配置上述技术问题。

以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明实施例公开了一种实现测量协调的方法,应用于无线通信系统中,所述无线通信系统包括:UE、主网元(Master Node,MN)、辅网元(Secondary Node,SN)和核心网;其中,所述主网元和辅网元为两个不同的基站,UE通过主网元接入核心网,主网元和辅网元之间形成通信连接,所述主网元和辅网元能够分别对所述UE进行测量配置;
这里,无线通信系统可以采用图1至图3所示的LTE-NR tight
Interworking架构,也可以采用其他系统架构;并且不对上述记载的无线通信系统的基站类型、基站个数、核心网类型、基站与基站之间的接口类型、以及基站与核心网之间的接口类型进行限制;示例性地,主网元和辅网元均可以是LTE eNB、NR gNB等基站,核心网可以是EPC、NGC等等,主网元和辅网元间可以建立CP接口和UP接口,主网元和核心网之间可以建立CP接口,可选地,主网元和核心网之间还可以建立UP接口,可选的,辅网元与核心网间也可以建立UP接口。
对于UE而言,UE在主网元的服务小区称为主小区组(Master Cell Group,MCG);若UE在主网元一侧配置了CA,则MCG中包括一个主服务小区和至少一个辅服务小区;若UE在主网元一侧未配置CA,也可以将UE在主网元一侧的服务小区称为UE在主网元中的主服务小区;UE在辅网元的服务小区称为辅小区组(Secondary Cell Group,SCG),若UE在辅网元一侧配置了CA,则SCG中包括一个主服务小区和至少一个辅服务小区,这里,可以将SCG中的主服务小区记为PSCell(角色类似于PCell,如同样适用于Event A5等),也可以将SCG中的辅服务小区记为SCell;若UE在辅网元一侧未配置CA,也可以将UE在辅网元一侧的服务小区称为UE在辅网元中的主服务小区。
上述记载的主网元和辅网元可以采用相同的RAT,也可以采用不同的RAT;在用户面,主网元与辅网元均为UE提供无线资源以进行数据的传输;在控制面,主网元与UE间在无线接口上会建立无线资源控制(Radio Resource Control,RRC)连接,而辅网元与UE间是否可直接传输RRC信令是可选的;也就是说,辅网元侧的RRC信令(可以简称为SN RRC信令)可以直接在SN与UE间的无线接口上进行传输,也可以在经过主网元的中转后,在主网元与UE间的无线接口上进行传输;而无论SN RRC信令的传输路径如何,SCG侧的无线资源配置主要还是由SN决定的;进一步的,主网元与辅网元生成的无线资源配置信息可以分别使用对应于各自所用RAT的RRC协议的抽象语法标记(Abstract Syntax Notation One,ASN.1)进行编码。
本发明实施例中,对于测量操作而言,将主网元对UE的测量配置称为主测量配置(Master Measurement Configuration,MMC);从无线资源管理
的角度来说,由于主网元会负责辅网元的选择/添加、切换和释放等操作,所以在主测量配置中,会包含对辅网元的服务小区、以及其相邻小区的测量配置;另一方面,因为辅网元会负责管理SCG的配置(如选择PSCell)和资源调度等操作,因此,辅网元也会对UE进行测量配置(本专利将其称为辅测量配置);将辅网元对UE的测量配置称为辅测量配置(Secondary Measurement Configuration,SMC),进一步的,根据自身的邻区关系和资源管理等需求,辅测量配置中会包含针对SCG中的所有小区及其邻区的测量配置。其中,主测量配置与辅测量配置可以是由主网元与辅网元独立决策的(两网元间的协调是可选的),并分别通过主网元与辅网元的控制面信令在无线接口上发送给UE。
基于上述记载的无线通信系统,提出以下各实施例。

可以理解的是,基于辅网元中的主服务小区的无线信号质量原因,和/或资源符合原因,和/或其他原因,辅网元可以决定将UE从源主服务小区切换至目标主服务小区,此时,可以配置UE执行一次由辅网元触发的网元内(intra-NB)小区间(inter-cell)类型的切换程序;这里,源主服务小区和目标主服务小区的频点不相同,即,源主服务小区和目标主服务小区属于异频小区;可以看出,由于UE所归属的辅网元并没有进行切换,所以,在现有技术中(比如在辅网元不需要向主网元请求安全机制相关的参数时),辅网元不会将所述目标主服务小区切换的相关信息通知给主网元。这里,需要说明的是,上述记载的服务小区之间的“切换”时对标准协议(如LTE系统的36系列协议)中“handover”或“change”的意译,也就是说,UE在辅网元的一个主服务小区发生了改变。例如,UE与辅网元上的小区
均为辅小区(Secondary Cell,SCell),辅网元中的小区又分为主服务小区和辅服务小区,辅网元中的主服务小区称之为PSCell为Primary Secondary Cell的缩写。辅网元中的辅小区称就是辅小区。
主网元提供的小区,也可以分为主服务小区和辅服务小区,但是主网元中的主服务小区称之为PCell,与辅网元中的主服务小区SPCell是不同的小区。
对于向UE发送指示信令的实现方式,在一个具体的示例中,可以将所述指示信令承载于控制面信令中,并将所述控制面信令发送至所述UE;这里,用于承载辅测量配置信息的控制面信令可以是RRC连接重配置消息,也可以是其他类型的控制面消息。
这里,辅网元对UE的测量配置信息(即初始SMC信息)包括第二测量标识列表,该第二测量标识列表包括与各个待测量频点对应的测量标识;这里的测量标识可以是测量目标的ID值,也可以用数字或其他种类的字符进行呈现,本发明实施例不对此进行限定。
可以看出,对于上述记载的切换过程,UE在辅网元侧的资源配置(如测量配置)进行了一次包括辅主频改变的更新,这里的辅主频指UE在辅网元中的主服务小区的频点;此时,UE可以将上述记载的测量标识列表中的测量标识按照以下方式进行更新:
在所述目标主服务小区的频点的测量标识存在于所述第二测量标识列表中时,在原有的辅网元对UE的测量配置信息中,将联结到所述源主服务小区的测量目标的测量标识更改为:联结到所述目标主服务小区的测量目标;将联结到所述目标主服务小区的测量目标的测量标识更改为:联结到所述源主服务小区的测量目标;这样的话,所述主网元对UE的测量配置信息包括:从联结到所述源主服务小区的测量目标的测量标识更改为的联结到所述目标主服务小区的测量目标;以及从联结到所述目标主服务小区的测量目标的测量标识更改为:联结到所述源主服务小区的测量目标。例如,辅网元的主服务小区为小区A,辅网元中的辅服务小区为小区B,在辅网元的源主服务小区为小区A,切换后的目标主服务小区为小区B,更新前所述主网元对UE的测量配置信息包括:主服务小区的测量对象为:小区A的
测量对象,辅服务小区的测量对象为:小区B的测量对象,主网元基于辅网元发送的标识信息,更新后所述主网元对UE的测量配置信息包括:小区B的测量对象,辅服务小区的测量对象为:小区A的测量对象。
在所述目标主服务小区的频点的测量标识不存在于所述第二测量标识列表中时,在原有的辅网元对UE的测量配置信息中,将联结到所述源主服务小区的测量目标的所有测量标识删除。在一些实施例中,若辅网元的源主服务小区的频点的测量标识不存在,在主网元更新对UE的测量配置信息时,直接删除源主服务小区的测量标识,故则,更新后的UE与辅网元对应的测量配置信息不包括:源服务小区的频点的频点标识。
在本实施例中,所述主网元对UE的测量配置信息,为主网元为UE提供的测量配置信息,例如,主网元为UE配置的测量辅小区的小区的配置信息。
可以看出,在辅网元一侧,UE中与源主服务小区的上报配置及相应的测量上报触发条件改换为:与目标主服务小区的上报配置及相应的测量上报触发条件;而UE中与目标主服务小区的上报配置及相应的测量上报触发条件改换为:与源主服务小区的上报配置及相应的测量上报触发条件。
那么,为了主网元能够进行有效地针对辅测量配置进行测量配置,主网元的测量配置(即主测量配置)也需要进行相应的更新。
步骤42:辅网元或UE向主网元发送所述目标主服务小区的标识信息,使所述主网元基于所述目标主服务小区的标识信息更新主网元对UE的测量配置信息;例如,所述标识信息,用于触发所述主网元,基于所述目标主服务小区的标识信息,更新与所述主网元对UE的测量配置信息,即所述主网元接收到该标识之后,会自动更新主网元内存储的主网元对UE的测量配置信息。
或者,
UE基于所述目标主服务小区的标识信息,更新所述主网元对UE的测量配置信息,并将更新后的测量配置信息上报至主网元,使所述主网元处理UE上报的测量配置信息;其中,所述标识信息,用于触发基于所述目标主服务小区的标识信息,处理UE上报的测量配置信息;
或者,
UE基于所述目标主服务小区的标识信息,更新所述主网元对UE的测量配置信息;基于更新后的测量配置信息上报测量结果的同时,上报所述测量结果对应的小区信息,使所述主网元基于所述测量结果对应的小区信息更新主网元对UE的测量配置信息,其中,所述测量结果对应的小区信息至少包括所述目标主服务小区的标识信息。相当于,其中,所述测量结果及所述小区信息,用于供所述主网元基于所述测量结果对应的小区信息更新所述主网元对UE的测量配置信息,所述测量结果对应的小区信息至少包括:辅网元的所述目标主服务小区的标识信息。
示例性的,上述目标主服务小区的标识信息包括以下至少一项:所述目标主服务小区的频点、所述目标主服务小区的小区索引、所述目标主服务小区的物理层小区标识;例如,上述目标主服务小区的标识信息为所述目标主服务小区的频点(可以称为目标辅主频的频点)。
可以看出,本步骤至少可以采用三种方式实现,其中,
第一种方式为:辅网元向主网元发送所述目标主服务小区的标识信息,使所述主网元基于所述目标主服务小区的标识信息更新主网元对UE的测量配置信息;
第二种方式为:UE向主网元发送所述目标主服务小区的标识信息,使所述主网元基于所述目标主服务小区的标识信息更新主网元对UE的测量配置信息;
第三种方式为:UE基于所述目标主服务小区的标识信息,更新所述主网元对UE的测量配置信息,并将更新后的测量配置信息上报至主网元,使所述主网元处理UE上报的测量配置信息;或者,UE基于所述目标主服务小区的标识信息,更新所述主网元对UE的测量配置信息;基于更新后的测量配置信息上报测量结果的同时,上报所述测量结果对应的小区信息,使所述主网元基于所述测量结果对应的小区信息更新主网元对UE的测量配置信息,其中,所述测量结果对应的小区信息至少包括所述目标主服务小区的标识信息。
下面分别对上述三种方式进行示例性说明。
第一种方式:
在实际实施时,辅网元可以通过主网元和辅网元之间的网元间接口向主网元发送指示信息,该指示信息包括所述目标主服务小区的标识信息;可选的,在本步骤中,UE可以对目标主服务小区进行测量,并将得到的针对目标主服务小区的测量结果上报至辅网元,此时,上述记载的指示信息还可以包括UE向辅网元上报的针对目标主服务小区的测量结果。
可选的,辅网元可以利用网元间接口的应用层协议的ASN.1对上述指示信息进行编码,并将编码生成的信息发送至主网元;所述网元间接口为主网元和辅网元之间的接口;如此,主网元在接收到来自辅网元的信息后,可以对接收的信息进行相应的解码,从而获得上述指示信息。
可选的,辅网元可以将上述指示信息承载于一个现有的或新增的网元间接口消息中,并将所述网元间接口消息发送至所述主网元。
第二种方式:
在实际实施时,UE可以通过UE主网元之间的无线接口向主网元发送目标主服务小区的标识信息。
可选的,UE可以利用对应于主网元使用的RAT的RRC协议的ASN.1,对所述目标主服务小区的标识信息进行编码,将编码生成的信息发送至主网元;如此,主网元在接收到来自辅网元的信息后,可以对接收的信息进行相应的解码,从而获得上述目标主服务小区的标识信息。
可选的,UE可以将所述目标主服务小区的标识信息承载于一个现有的或新增的RRC信令中,并将所述RRC信令发送至主网元。
对于第一种方式和第二种方式,主网元在收到目标主服务小区的标识信息后,可以基于所述目标主服务小区的标识信息更新主网元对UE的测量配置信息;在一个可选的实施例中,主网元基于目标主服务小区的标识信息,生成主网元对UE的测量配置信息(即更新后的MMC);
具体地说,所述主网元对UE的测量配置信息包括第一测量标识列表,所述第一测量标识列表包括与各个待测量频点对应的测量标识;
所述主网元基于所述目标主服务小区的标识信息更新主网元对UE的
测量配置信息,包括:
在所述目标主服务小区的频点的测量标识存在于所述第一测量标识列表中时,在原有的主网元对UE的测量配置信息中,将联结到所述源主服务小区的测量目标的测量标识更改为:联结到所述目标主服务小区的测量目标;将联结到所述目标主服务小区的测量目标的测量标识更改为:联结到所述源主服务小区的测量目标;
在所述目标主服务小区的频点的测量标识不存在于所述第一测量标识列表中时,在原有的与主网元对UE的测量配置信息中,将联结到所述源主服务小区的测量目标的所有测量标识删除。
之后,将所述更新后的主网元对UE的测量配置信息发送至所述UE。可选地,在更新与主网元对UE的测量配置信息时,还可以将当前的无线资源管理需求作为依据。
可选地,在将更新后的主网元对UE的测量配置信息发送至所述UE后,UE可以基于接收到的测量配置信息进行测量,并将得到的测量结果上报至主网元。
第三种方式:
可以理解的是,在UE基于所述目标主服务小区的标识信息,更新所述主网元对UE的测量配置信息时,可以更新MMC中的辅主频及PSCell信息;这里,所述主网元对UE的测量配置信息的更新方式可以与辅测量配置中目标主服务小区的标识信息的更新方式相同。
可以看出,对于第三种方式,在UE更新所述主网元对UE的测量配置信息后,在一种具体的实施方式中,UE可以立即将更新后的测量配置信息(即更新的MMC)上报至主网元,这里,更新后的测量配置信息可以是MMC中的更新的测量配置部分,也可以包括完整的MMC;
示例性地,主网元在收到UE上报的测量配置信息后,可以针对UE上报的测量配置信息进行决策,得出决策结果,这里的决策结果可以是:确定同意采用UE上报的测量配置信息,或者,需要对UE上报的测量配置信息进行修改,或者,拒绝采用UE上报的测量配置信息;当主网元确定需要
采用UE上报的测量配置信息时,将UE上报的测量配置信息确定为主网元对UE的测量配置信息;当主网元确定需要修改UE上报的测量配置信息时,通知UE修改所述更新后的测量配置信息,在实际实施时,主网元可以通过无线接口通知UE;当主网元确定拒绝采用UE上报的测量配置信息时,通知UE拒绝采用更新后的测量配置信息,在实际实施时,主网元可以通过无线接口通知UE。
可以理解的是,在主网元确定需要采用UE上报的测量配置信息时,可以更新主网元内存储的针对所述UE的MMC信息;可选的,在主网元确定需要采用UE上报的测量配置信息时,主网元还可以向UE发送响应消息,以使UE获知主网元已经同意采用UE上报的测量配置信息。
根据更新后的测量配置信息执行对辅网元一侧的测量,在满足了针对目标主服务小区的测量上报触发条件后,UE向主网元上报测量结果以及测量结果对应的测量配置信息。
对于第三种方式,在另一种具体的实施方式,UE可以基于更新后的测量配置信息上报测量结果的同时,上报所述测量结果对应的小区信息,使所述主网元基于所述测量结果对应的小区信息更新主网元对UE的测量配置信息,其中,所述测量结果对应的小区信息至少包括所述目标主服务小区的标识信息。
此时,所述主网元基于所述测量结果对应的小区信息更新主网元对UE的测量配置信息,包括:
在原有的主网元对UE的测量配置信息中,将所述源主服务小区的频点对应的测量标识重新配置为:与所述目标主服务小区的频点对应的测量标识,得到更新后的主网元对UE的测量配置信息,将所述更新后的主网元对UE的测量配置信息发送至所述UE。
本发明第一实施例的实现测量协调的方法,可以应用于未来广泛部署的通信网络及相应的系统架构中,应用本发明第一实施例的实现测量协调的方法,会使得主网元和辅网元都能够及时的获取到满足期各自的无线资源管理需求的测量结果上报。另外,本发明实施例在没有明显增大信令负荷的情况下,实现了多服务网元对资源配置的协调更新,由此,使得主/辅
网元能够以紧耦合的方式为UE提供高效、可靠的数据传输服务、提升了UE侧的用户体验。
第二实施例
为了能够更加体现本发明的目的,在本发明第一实施例的基础上,进行进一步的举例说明。
本发明第二实施例的应用场景为:在辅网元一侧,发生了辅网元内的主服务小区的变换时,对主测量配置进行更新。
图5为本发明实现测量协调的方法的第二实施例的数据交互流程的示意图,如图5所示,该流程包括:
步骤501:辅网元对UE进行辅测量配置。这里的辅网元对UE的辅测量配置,又可以简称辅网元对UE的测量配置,形成的是辅网元对UE的测量配置信息。
在实际实施时,辅网元可以根据当前的无线资源管理需求,配置辅网元中的一个小区作为UE在辅网元中的主服务小区(即源主服务小区),该源主服务小区的频点为辅网元一侧当前的辅主频;辅网元还可以配置辅网元中的另一个小区为当前源主服务小区的邻区;可以理解的是,在源主服务小区的每个邻区与源主服务小区异频。
对于本步骤的实施方式,在一个可选的实施例中,辅网元可以根据辅网元一侧当前的无线资源管理需求,对UE进行辅测量配置。例如,图6为本发明第二实施例中测量标识与上报配置的一个示意图,如图6所示,ID值为1的测量目标(即图6中测量目标ID_1)用于表示源主服务小区的频点,ID值为1的测量目标的测量标识为ID_1,ID值为2的测量目标(即图6中测量目标ID_2)用于表示源主服务小区的一个邻区的频点,ID值为2的测量目标的测量标识为ID_2;上报配置ID_1和上报配置ID_2分别表示两种不同的上报配置,可以看出,ID值为1的测量目标的测量标识联结到上报配置ID_1,也就是说,ID值为1的测量目标的上报配置为上报配置ID_1;同理,ID值为2的测量目标的测量标识联结到上报配置ID_2,也就是说,ID值为2的测量目标的上报配置为上报配置ID_2;也就是说,上报配置ID_1及相应的测量上报触发条件适用于源主服务小区的频点,而上报
配置ID_2及相应的测量上报触发条件适用于目标主服务小区的一个邻区的频点。
步骤502:UE将辅测量结果上报至辅网元。
在实际实施时,UE可以根据接收到的辅测量配置进行测量,在满足测量上报触发条件时,将测量结果上报至辅网元,这里的辅测量结果表示UE根据接辅测量配置进行测量得到的测量结果。
步骤503:辅网元进行PSCell切换决定。
示例性地,辅网元可以根据无线资源管理需求,决定将UE从源主服务小区(PSCell)切换到目标主服务小区,这里,目标主服务小区可以是源主服务小区的一个邻区;在实际实施时,辅网元可以采用无线资源管理算法确定是否需要切换源主服务小区、以及将UE从源主服务小区切换到哪个小区。
步骤504:辅网元向UE发送切换指示信息。
这里,辅网元可以通过一个无线接口的控制面信令向UE发送切换指示信息,切换指示信息的作用为:指示UE离开源主服务小区接入目标主服务小区,并指示UE进行相应的无线资源重配置;这里的控制面信令可以是RRC连接重配置信令,也可以是其他的控制面信令。
可以理解的是,UE的无线资源重配置可以包括UE的辅测量配置的更新。
步骤505:UE进行辅测量配置更新。
在实际实施时,UE可以进行无线资源重配置,同时,因为源主服务小区的频点与目标主服务小区的频点不同,因而,UE会进行辅测量配置更新;例如,对于图6所示的示意图,在UE进行辅测量配置更新时,图6中所示的测量目标与测量配置的对应关系会发生变化,即由图6变换至图7;图7为本发明第二实施例中测量标识与上报配置的另一个示意图,如图7所示,ID值为1的测量目标(即图7中测量目标ID_1)用于表示源主服务小区的频点,ID值为1的测量目标的测量标识为ID_1,ID值为2的测量目标用于表示目标主服务小区的频点,ID值为2的测量目标(即图7中测量目标
ID_2)的测量标识为ID_2;上报配置ID_1和上报配置ID_2分别表示两种不同的上报配置,可以看出,ID值为1的测量目标的测量标识联结到上报配置ID_2,也就是说,ID值为1的测量目标的上报配置为上报配置ID_2;同理,ID值为2的测量目标的测量标识联结到上报配置ID_1,也就是说,ID值为2的测量目标的上报配置为上报配置ID_1;也就是说,UE中针对辅主频的上报配置及相应的测量上报触发条件达到了与SN中为UE重配置的辅主频保持一致的效果。
步骤506:UE在目标主服务小区上实现向辅网元的随机接入。
步骤507:UE向辅网元回复与步骤503对应的响应消息,UE在满足测量上报条件时,将测量结果上报至辅网元。
本步骤中,UE发送的响应消息用于向辅网元通知以下信息:UE从源主服务小区(PSCell)切换到目标主服务小区的过程结束。
步骤508:辅网元向主网元发送指示信息。
这里,指示信息的作用至少是向主网元通知目标主服务小区的标识信息,指示信息还可以包括UE针对目标主服务小区的测量结果。
需要说明的是,本步骤只要在步骤503之后便可以执行,并非必须在步骤507后才可以执行。
步骤509:主网元向辅网元发送与步骤508对应的响应消息。
在实际实施时,主网元在接收并解读指示信息后,可以通过网元间接口向辅网元回复相应的响应消息。
步骤510:主网元进行主测量配置更新。
这里,主网元可以根据接收到的指示信息,更新主测量配置(即主网元对UE的测量配置信息),生成更新后的主测量配置信息。
步骤511:主网元向UE发送更新后的主测量配置信息。
示例性地,主测量配置信息可以指示UE进行主测量配置更新,例如,UE进行的主测量配置更新可以包括:将初始时联结源主服务小区的频点的测量配置改为联结到目标主服务小区的频点。也就是说,UE在进行主测量配置更新后,可以将初始时针对源主服务小区的上报配置及相应的测量上
报触发条件改换为针对目标主服务小区的上报配置及相应的测量上报触发条件。
可选的,UE在进行主测量配置更新时,可以更改或直接取消针对源主服务小区的上报配置,具体如何操作由主网元根据无线资源管理需求而决定。
这里的主测量配置信息可以承载于RRC连接重配置信令或其他控制面信令中发送,在一个可选的实施方式中,本步骤只要在步骤508之后便可以执行,并非必须在步骤510后才可以执行。
步骤512:UE进行主测量配置更新。
步骤513:UE向主网元发送主测量配置更新完成的响应消息。
步骤514:UE将测量结果上报至主网元。
在实际实施时,UE可以根据更新后的主测量配置信息进行测量,并在满足测量上报触发条件时进行测量结果上报。
第三实施例
为了能够更加体现本发明的目的,在本发明第一实施例的基础上,进行进一步的举例说明。
本发明第三实施例的应用场景与本发明第二实施例相同,这里不再赘述。
图8为本发明实现测量协调的方法的第三实施例的数据交互流程的示意图,如图8所示,该流程包括:
步骤801:本步骤的实现方式与步骤501至步骤507相同,这里不再赘述。
步骤802:UE向主网元发送指示信息,
这里,指示信息的作用与步骤508中指示信息的作用相同,这里不再赘述。
指示信息可以包括目标的目标主服务小区的频点、目标主服务小区的小区索引、以及目标主服务小区的物理层小区标识等信息,也可以仅包括
目标主服务小区的频点(此时需要指出该频点是当前配置的在辅网元一侧的新的主服务小区的频点)。
步骤803:主网元向UE发送成功接收指示信息的响应消息。
在实际实施时,主网元在解读指示信息后,可以通过无线接口向UE回复相应的响应消息,以确认主网元对指示信息的成功接收。
步骤804:本步骤的实现方式与步骤510至514相同,这里不再赘述。
需要说明的时,本发明第三实施例中,对于涉及的指示信息、主测量配置信息,只说明相应的作用,而不限制发送行驶,例如,主网元向UE发送的响应消息可以携带在一个控制面信令中。
第四实施例
为了能够更加体现本发明的目的,在本发明第一实施例的基础上,进行进一步的举例说明。
本发明第四实施例的应用场景与本发明第二实施例相同,这里不再赘述。
图9为本发明实现测量协调的方法的第四实施例的数据交互流程的示意图,如图9所示,该流程包括:
步骤901:本步骤的实现方式与步骤501至步骤507相同,这里不再赘述。
步骤902:UE进行主测量配置更新,也就是说,UE更新与所述主网元对UE的测量配置信息。
需要说明的是,本步骤需要在步骤901中进行辅测量配置更新后执行,本步骤的实现方式已经在第一实施例步骤42的第三种方式中作出说明,这里不再赘述。
步骤903:UE上报测量配置信息至主网元。
在一种具体的实施方式中,UE可以立即将更新后的测量配置信息(即更新的MMC)上报至主网元,这里,更新后的测量配置信息可以是MMC中的更新的测量配置部分,也可以包括完整的MMC;在另一种具体的实施方式,UE可以根据更新后的测量配置信息执行对辅网元一侧的测量,在满
足了针对目标主服务小区的测量上报触发条件后,UE向主网元上报测量结果以及测量结果对应的测量配置信息。
这里,本步骤的上报过程可以是一个单向信令程序(仅包括UE到主网元的上报过程),也可以是一个双向信令程序(不仅包括UE到主网元的上报过程,也包括主网元对UE的回复响应消息)。
步骤904:主网元进行主测量配置更新。
示例性地,主网元在收到UE上报的测量配置信息后,可以针对UE上报的测量配置信息进行决策,得出决策结果,这里的决策结果可以是:确定同意采用UE上报的测量配置信息,或者,需要对UE上报的测量配置信息进行修改,或者,拒绝采用UE上报的测量配置信息;当主网元确定需要采用UE上报的测量配置信息时,将UE上报的测量配置信息确定为主网元对UE的测量配置信息;当主网元确定需要修改UE上报的测量配置信息时,通知UE修改所述更新后的测量配置信息,在实际实施时,主网元可以通过无线接口通知UE;当主网元确定拒绝采用UE上报的测量配置信息时,通知UE拒绝采用更新后的测量配置信息,在实际实施时,主网元可以通过无线接口通知UE。
步骤905:UE将测量结果上报至主网元。
示例性地,在主网元确定需要采用UE上报的测量配置信息时,主网元还可以向UE发送响应消息,以使UE获知主网元已经同意采用UE上报的测量配置信息,此时,UE根据相应的主测量配置信息执行测量,并在满足测量上报触发条件时进行测量结果上报。
第五实施例
针对本发明第一实施例的方法,本发明第五实施例提出了一种实现测量协调的系统。
图10为本发明实施例的实现测量协调的系统的结构示意图,如图10所示,该系统包括:用于对同一个用户设备UE 1001进行测量配置分别进行测量配置的主网元1002和辅网元1003;其中,所述主网元1002和辅网元1003为两个不同的基站;
