具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。针对本申请中的实施例,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,都属于本申请保护的范围。
本申请实施例可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、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)、长期演进(Long Term Evolution,LTE)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
可选地,本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation,CA)场景,也可以应用于双连接(Dual Connectivity,DC)场景,还可以应用于独立(Standalone,SA)布网场景。
本申请实施例对应用的频谱并不限定。例如,本申请实施例可以应用于授权频谱,也可以应用于免授权频谱。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。
图1示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
本申请实施例结合终端设备和网络设备描述了各个实施例,其中:终端设备也可以称为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION,ST),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统,例如,NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备,网络设备可以是WLAN中的接入点(Access Point,AP),GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者车载设备、可穿戴设备以及NR网络中的网络设备(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
应理解,与LTE系统相似,NR系统支持切换过程。当正在使用网络服务的用户从一个小区移动到另一个小区,或由于无线传输业务负荷量调整、激活操作维护、设备故障等原因,为了保证通信的连续性和服务的质量,系统要将该用户与原小区的通信链路转移到新的小区上,即执行切换过程。
切换过程例如可以如图2所示,整个切换过程分为以下三个阶段:
第一阶段,切换准备(1~5)
在1中,源基站触发终端设备进行邻区测量,从而终端设备可以对邻区进行测量,并将测量结果上报给源基站。
在2中,源基站对终端设备上报的测量结果进行评估,决定是否触发切换。
在3中,若源基站决定触发切换,则可以向目标基站发送切换请求。
在4中,目标基站接收到源基站发送的切换请求后,可以根据源基站携带的业务信息开始准入,并进行无线资源配置。
在5中,目标基站向源基站发送切换请求确认消息,将在目标基站内的准入结果和无线资源配置信息返回给源基站。至此,切换准备阶段完成。
第二阶段,切换执行(6~8)
在6中,源基站接收到目标基站的切换请求确认消息后,可以触发终端设备进行切换。
在7中,源基站可以将缓冲数据、在传数据包、数据的系统序列号等转发给目标基站。并且,目标基站可以缓存从源基站接收的数据
此外,终端设备可以断开与源基站的连接,与目标基站建立同步。
在8中,终端设备同步到目标基站。至此,切换执行阶段完成。
第三阶段,切换完成(209~212)
在9中,目标基站向移动性管理功能(Access and Mobility Management Function,AMF)发送路径切换请求。
在10中,AMF接收到目标基站的路径切换请求后,与用户面功能(User Plane Function,UPF)执行路径切换,清除源基站用户面的路径标记。
在11中,在路径切换完成之后,AMF可以向目标基站发送路径切换确认消息。
在12中,目标基站向源基站发送终端设备上下文释放消息,通知源基站切换成功,并触发源基站终端设备上下文。至此,切换完成。
应理解,在本申请实施例中,针对高速移动场景和高频部署场景存在频繁切换以及切换容易失败的问题,第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)中可以考虑在LTE和NR系统引入基于条件触发的切换过程,其基本原理是:终端设备根据网络侧配置的条件在评估与目标小区相关的条件触发时按照预先配置好的切换命令执行向该目标小区的切换(即触发随机接入过程和发送切换完成消息),避免由于高速移动进入覆盖差区域来不及或无法发送测量上报和接收到切换命令的问题。
具体地,基于条件触发的切换过程可以如图3所示,基于条件触发的切换过程包括:
21,源基站向终端设备发送测量配置信息;
22,终端设备向源基站发送测量报告;
23,源基站与目标基站交互切换准备信息;
24,源基站向终端设备发送切换命令;
该切换命令包括针对小区或者波束的条件信息。
25,当条件满足时终端设备与目标基站进行同步(终端设备接入目标基站)。
在基于条件触发的切换过程(预配置切换过程)中,切换消息不是立即起效,例如,终端设备可能很长时间后才切换到目标小区,或者切换失败,在这种情况下,源小区始终没有得到响应消息,这对于源小区来说会导致处理的不确定性。基于上述问题,本申请提供了一种小区切换方法,终端设备可以及时向源小区和/或目标小区反馈响应信息,源小区也可以及时接收到响应信息,从而,源小区可以及时获知终端设备的切换进程。
需要说明的是,本申请实施例可以应用于基于条件触发的切换过程,以下结合具体实施例阐述本申请实施例的小区切换方法。
图4是根据本申请实施例的小区切换方法200的示意性流程图,如图4所示,该方 法200可以包括如下内容:

可选地,在本申请实施例中,服务于该第一小区的网络设备还用于指示该终端设备进行针对该第一配置信息的反馈。此时,在满足上述第一条件或者第二条件的情况下,该终端设备还需根据该指示向服务于该第一小区的网络设备和/或服务于该第二小区的网络设备发送响应信息。

又例如,若该第一配置信息还用于指示该终端设备进行针对该第一配置信息的反馈,该终端设备根据该第一配置信息向服务于该第一小区的网络设备和/或服务于该第二小区的网络设备发送响应信息。
可选地,在本申请实施例中,针对服务于该第一小区的网络设备的响应信息用于指示接受该第一配置信息。
