具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例提供的小区连接方法进行详细说明之前,先对相关技术小区切换过程进行简要说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性,3GPP国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications,URLLC)、和大规模机器类通信(Massive Machine Type Communication,mMTC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
与长期演进(Long Term Evolution,LTE)***相似,新无线(New Radio,NR)***支持连接态终端设备的切换过程。当正在使用网络服务的终端设备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,***要将该终端设备与原小区的通信链路转移到新的小区上,即执行切换过程。
以Xn接口切换过程为例,适用于LTE***以及NR***的小区切换过程,如图1所示,分为以下三个阶段:
阶段1(包括步骤1至5),切换准备:包括测量控制和汇报,切换请求以及确认。
阶段2(包括步骤6至8),切换执行:终端设备在收到切换命令后立即执行切换过程,即终端设备断开源小区并与目标小区连接(如执行随机接入,发送RRC切换完成消息给目标网络设备等);辅节点(Secondary Node,SN)状态转移,数据转发。
阶段3(包括步骤9至12),切换完成:目标小区与(Acess and Mobility Management Function,AMF)和用户面功能(User Port Function,UPF)执行路径切换(path switch),释放源网络设备的终端设备上下文。
在LTE***和NR***的3GPP移动性增强研究中,对于终端设备在进行小区切换时减小连接中断时间的架构,包括下述两种:
一种是在小区切换过程中,首先将目标网络设备添加为辅节点(Secondary Node,SN);再通过角色转换(role change)信令将目标网络设备由SN转换为主节点(Master Node,MN);最后释放源网络设备,从而达到小区切换时减小连接中断时间的效果。
另一种是减少小区切换过程中减小中断时间的双激活协议栈(Dual Active Protocol Stack,DAPS)优化方法,即终端设备在接收到切换命令时,终端设备同时保持与源小区和目标小区的协议栈,同时向目标网络设备发起随机接入,终端设备成功接入目标小区后,目标网络设备会向核心网网元发起路径切换请求,用于请求核心网网元将下行路径从源网络设备切换至目标网络设备。对于DAPS的切换而言,终端设备会同时保持与源网络设备和目标网络设备之间的连接;终端设备只向目标网络设备发送上行数据,终端设备同时接收源网络设备和目标网络设备发送的下行数据。同时,终端设备保持对于源网络设备对应的源小区和目标网络设备对应的目标小区的无线链路监测(Radio Link Monitoring,RLM)。。若终端设备在成功接入目标小区后,终端设备与目标小区之间发生了无线链路失败,终端设备如何进行小区连接能够避免不必要的连接重建过程是需要解决的问题。
其中,无线链路失败包括下述中的至少一种情况:物理层无线链路问题指示之后启动的定时器超时、随机接入过程失败、以及无线链路控制(Radio Link Control,RLC)失败。
本申请提供一种小区连接方法,本申请实施例的小区连接方法可以应用于各种通信***,例如:全球移动通讯(Global System of Mobile communication,GSM)***、码分多址(Code Division Multiple Access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***、通用分组无线业务(General Packet Radio Service,GPRS)、LTE***、LTE频分双工(Frequency Division Duplex,FDD)***、LTE时分双工(Time Division Duplex,TDD)、通用移动通信***(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信***或5G***等。
