技术领域
本申请涉及通信技术领域,更具体地涉及用于小区变换的方法和设备。
背景技术
无线通信系统的终端设备和网络设备通信期间,由于移动性,连接态的终端设备可能从一个基站的覆盖区域移到另一个基站的覆盖区域,此时终端设备需要将原有无线信道转换至新的无线信道,即完成切换(Handover)。
长期演进系统(Long Term Evolution,LTE)系统中,切换失败主要是因为终端设备不能及时收到源基站下发的切换命令。在新空口(New Radio,NR)系统中,小区部署更为密集,小区覆盖范围相对较小,这会导致终端设备更为频繁的执行切换。如果在终端设备移动到另一个基站的覆盖区域内还没有收到源基站下发的切换命令就会导致切换失败。因此,在NR中,继续沿用LTE系统的切换方法会导致切换失败概率提升。
为了缓解上述问题,第五代移动通信技术(5th-Generation,5G)中引入了条件切换(Conditional Handover)的方式,条件切换的方式中终端设备需要接收网络设备发送的小区变换配置信息,并在基于小区变换配置信息确定满足触发条件时进行小区变换,但目前网络设备发送给终端设备的小区变换配置信息的内容尚未确定,导致无线通信的有效性较低。

本公开的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(Global System of Mobile communication,GSM),码分多址(Code Division Multiple Access,CDMA)系统,宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统,通用分组无线业务(General Packet Radio Service,GPRS)系统,长期演进(Long Term Evolution,LTE)/增强长期演进(Long Term Evolution-advanced,LTE-A)系统,新无线(New Radio,NR)系统等。

S110,接收源节点发送的小区变换配置信息,所述小区变换配置信息包括以下信息中的至少一种:用于终端设备确定目标小区的信息、小区变换触发条件信息、小区变换命令、以及与小区变换相关的关联关系信息。
可以理解的是,小区变换配置信息可以由目标节点发送给源节点,之后 由源节点转发给终端设备的。
可选地,在一些实施例中,用于终端设备确定目标小区的信息包括目标小区的标识信息和频点信息,标识信息例如可以为目标小区的标识(Identifier,ID),目标小区的ID例如可以是目标小区的物理小区标识(Physical Cell Identifier,PCI)。在目标小区的数量为多个时,目标小区的ID可以为多个小区的列表或小区索引(Cell Index)。
可选地,在一些实施例中,小区变换触发条件信息包括以下信息中的至少一种:测量配置、测量触发时间(Time to Trigger,TTT)、以及小区变换触发方式。
作为一个例子,测量配置包括以下信息中的至少一种:测量触发事件(例如,终端设备特定的(UE Specific)测量触发事件或者小区特定(Cell Specific)测量触发事件)、测量对象(例如,频点或者带宽部分(Bandwidth Part,BWP))、测量量(例如,参考信号接收功率(Reference Signal Receiving Power,RSRP)、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)、信干噪比(Signal to Interference Plus Noise Ratio,SINR))、测量参考信号的类型(例如,同步信号块(Synchronization Signal Block,SSB)、信道状态信息-参考信号(Channel State Information-Reference Signal,RS))、测量起始门限、测量终止门限、以及测量持续时间。测量持续时间指的是测量有效触发需要持续在TTT时间内均达到,方可触发条件小区变换。小区变换触发方式可以为以下触发方式中的一种:事件触发、周期性触发、以及非周期性触发。
可选地,在一些实施例中,小区变换命令包括以下信息中的至少一种:终端设备的标识信息、目标小区的空口配置、目标小区的安全信息、以及终端设备的小区变换能力。在这里,终端设备的标识信息可以为终端设备的ID。目标小区的空口配置可以包括层级配置、数据无线承载(Data Radio Bearer,DRB)和/或信令无线承载(Signaling Radio Bearer,SRB)配置等相关空口资源指示和配置。目标小区的安全信息包括空口安全信息和非接入层(Non-Access-Stratum,NAS)安全信息。终端设备的小区变换能力包括以下能力中的一种:先接后断(Make Before Break,MBB)的小区变换、免随机接入过程(Random Access Channel Less,RACH Less)的小区变换;以及双 连接切换(Dual Connectivity Handover,DC Handover)。在这里,终端设备的小区变换能力也可以理解为终端设备进行小区切换时采用的切换方式。
作为一个例子,小区变换命令的数量为1个或多个,每个小区变换命令为无线资源控制(Radio Resource Control,RRC)消息或以容器(Container)的形式内嵌在RRC消息中;或,小区变换命令的数量为多个,且多个小区变换命令存放在同一个容器中。换言之,每个小区变换命令可以以RRC消息的方式存在,也可以以Container的方式存在,也可以一组小区变换命令放在一个Container中。
可选地,在一些实施例中,与小区变换相关的关联信息中包括的关联关系包括以下任一项之间的关联关系:目标小区或目标小区列表(Cell List)或目标小区组(Cell Group)、测量对象、测量配置、小区变换触发条件信息、以及小区变换命令。
举例来说,与小区变换相关的关系信息包括:目标小区、小区变换触发条件信息、以及小区变换命令之间的关联关系。或者与小区变换相关的关联关系包括:目标小区组、小区变换触发条件信息组、以及小区变换执行命令之间的关联关系。或者与小区变换相关的关联关系信息包括:目标小区、测量配置、以及小区变换切换命令之间的关联关系。或者与小区变换相关的关联信息包括:测量配置和测量对象的关联关系。其中,上述的关联关系可以是通过具有关联关系的各项的ID建立的关联关系,可以是通过比特位图Bitmap建立的关联关系,也可以是通过测量对象中的白名单建立的关联关系。并且在这里的关联关系可以是一对一的关联关系、一对多的关联关系、多对多的关联关系以及链条式关联关系。
作为一个例子,关联关系包括目标小区、小区变换命令、测量配置、以及测量对象之间的关联关系,且关联关系通过具有关联关系的各项的标识建立,则用于描述上述关联关系的信令结构可以如下信令结构1和信令结构2所示。其中,信令格式1为:
{CHO-ID,cho-CMD-ID,evaluationConfigId,measObjectID}
其中,CHO-ID标识了本条件变换小区实体(目标小区);cho-CMD-ID标识了对应于本ID的变换命令实体(小区变换命令);evaluationConfigId标 识了对应于该CHO-ID的评估测量配置(测量配置));measObjectID标识了对应于CHO-ID的测量对象。
其中,evaluationConfigId对应的评估测量配置(evaluationConfig)包括:
{测量触发事件,测量对应的门限,Cell白名单,测量RS的类型,测量量,测量滤波器(Filter)参数,比较时间,结果有效期}等测量比较评估相关参数
信令格式2为:

其中,CHO-config关联了测量配置(evaluationConfig)、测量对象(measObject),CHO-execute对于执行实体,关联了cho-configID和cho-CMD命令对应的目标小区。
S120,根据所述小区变换配置信息执行小区变换相关操作。
具体地,在一些实施例中,终端设备根据小区变换配置信息执行的小区变换相关操作可以包括:终端设备根据小区变换配置信息确定是否满足小区切换触发条件,在满足小区切换触发条件时选择一个用于小区切换的目标小区。在目标小区发起随机接入过程,在随机接入过程完成后终端设备向目标节点发送切换完成信息,并断开与源节点之间的连接,使得源节点向其他目标节点发送取消条件切换命令,并接收其他目标节点发送的条件切换取消确认命令。
进一步地,为了使得源节点能够获知终端设备是否会进行小区变换,以及如果进行小区变换的话,在何时进行小区变换。终端设备可以在接收到小区变换配置信息之后向源节点发送小区变换指示信息,该小区变换指示信息用于源节点确定终端设备在发送小区变换指示信息之后是否进行小区变换。由此可以避免源节点一直为终端设备保留资源带来的资源浪费。
在本公开实施例中,可选地,S110中接收源节点发送的小区变换配置信息,包括:接收源节点发送的RRC重配置消息,所述RRC重配置消息中包 括所述小区变换配置信息;相对应的,在S120之前,图1所示的方法还包括:以变量的形式存储所述小区变换配置信息。进而本公开实施例的方法进一步明确了终端设备保存的变量内容,进一步提高通信有效性。
具体地,在一些实施例中,以变量的形式存储小区变换配置信息包括以下存储方式中的一种:将所述RRC重配置消息作为一个目标变量进行存储;将所述RRC重配置消息设置为一个目标容器,将所述目标容器作为一个目标变量进行存储;将所述小区变换配置信息作为一个目标变量进行存储;以及,将所述小区变换配置信息设置为一个目标容器,将所述目标容器作为一个目标变量进行存储。
举例来说,将RRC重配置消息设置为一个目标容器,将目标容器作为一个目标变量进行存储的信令格式可以为:UE_VarRRCRecofig Octet String(Container)。
或者又例如,将小区变换配置信息作为一个目标变量进行存储的信令格式可以为如下的信令格式3,信令格式3中大括号中的变量对应小区变换配置信息中包括的信息,这里的变量只是举例,并不是对变量的限定。
信令格式3:

或者再例如,将小区变换配置信息设置为一个目标容器,将目标容器作为一个目标变量进行存储的信令格式可以为:UE_VarCHO Octet String。
具体地,在另一些实施例中,将所述小区变换配置信息中包括的信息作为单独的变量进行存储;将所述小区变换配置信息中包括的信息中的一部分信息作为单独的变量进行存储,将所述小区变换配置信息中包括的信息中的另一部分信息设置为目标容器,并将所述目标容器作为一个目标变量进行存 储,或将所述小区变换配置信息中包括的信息中的另一部分信息作为组变量进行存储;以及,将所述小区变换配置信息中包括的信息中的至少部分信息复用目标协议中的变量进行存储,所述目标协议为相关技术中的通信协议。
举例来说,将小区变换配置信息中包括的信息中的一部分信息作为组变量进行存储的信令格式可以为如下的信令格式4,信令格式4中的VarMeasCHO sequence和VarchoCMD sequence组变量,VarMeasCHO sequence对应的大括号中的变量对应小区变换配置信息中包括的信息,VarchoCMD sequence对应的大括号中的变量对应小区变换配置信息中包括的信息。同样的,这里的变量只是举例,并不是对变量的限定。信令格式4具体为:

Var_measCHO
Var_ConfigCHO
Var_cell
Var_CMD Octet String
Var_trigger
…。
需要说明的是,本公开上述实施例中的小区变换配置信息还可以用于源节点和目标节点之间进行与小区变换相关的协商流程中,进而使得本公开实施例的方法能够明确网络设备之间协商的配置信息内容,进一步提高通信的有效性。
可选地,在一些实施例中,在小区变换配置信息用于源节点和目标节点之间进行与小区变换相关的协商流程中时,小区变换配置信息还包终端设备的测量结果,或者小区变换配置信息还包括源节点或目标节点对终端设备的测量结果的预测值。由此可以为源节点和目标节点之间协商小区变换触发条件提供合理的依据。
