Description

一种终端上下文的获取方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种终端(UE，User Equipment)上下文的获取方法及装置、计算机存储介质。
背景技术
为了满足人们对业务的速率、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、复杂性，第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)国际标准组织开始研发第五代(5G，5th Generation)移动通信技术。
5G移动通信技术的主要应用场景为：增强型移动宽带(eMBB，Enhance Mobile Broadband)、低时延高可靠通信(URLLC，Ultra Reliable Low Latency Communication)、大规模机器类通信(mMTC，massive Machine Type Communication)。
5G移动通信技术也称为新一代无线通信技术(NR，New Radio)，在NR早期部署时，完整的NR覆盖很难达到，所以典型的网络覆盖是长期演进(LTE，Long Term Evolution)覆盖和NR覆盖的结合。此外，为了保护移动运营商前期在LTE上的投资，提出了LTE和NR之间的紧耦合(tight interworking)工作模式。在双连接(DC，Dual Connectivity)架构中，由两个网络节点为UE提供服务，一个是主节点(MN，Master Node)，另一个是辅节点(SN，Secondary Node)。
在UE切换过程中，一般将源小区的UE上下文发送给目标小区，目标小区根据源小区的UE上下文发进行无线资源控制(RRC，Radio Resource Control)配置。然而，在EN-DC架构中，UE的上下文存储在两个位置， 分别是MN和SN；MN并不知道SN侧的UE上下文，所以在UE切换过程中源MN转移给目标MN的UE上下文中并不包括SN侧的UE上下文，导致目标MN无法为UE配置出合理的无线资源，与此同时，可能会导致UE切换失败。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本发明实施例的技术方案主要应用于5G移动通信系统，当然，本发明实施例的技术方案并不局限于5G移动通信系统，还可以应用于其他类型的移动通信系统。以下对5G移动通信系统中的主要应用场景进行说明：
1)eMBB场景：eMBB以用户获得多媒体内容、服务和数据为目标，其业务需求增长十分迅速。由于eMBB可能部署在不同的场景中，例如室 内、市区、农村等，其业务能力和需求的差别也比较大，所以必须结合具体的部署场景对业务进行分析。
2)URLLC场景：URLLC的典型应用包括：工业自动化、电力自动化、远程医疗操作、交通安全保障等。
3)mMTC场景：URLLC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。
在LTE和NR之间tight interworking的工作模式中，SN有自己的信令无线承载(SRB，Signalling Radio Bearers)，即SRB3，通过SRB3可以配置辅小区组(SCG，Slave Cell Group)中的scell的管理信息以及测量信息。
此外，MN和SN独立给UE配置测量配置信息，具体地，MN通过LTE中的RRC消息向UE发送测量配置信息，UE向MN上报与该测量配置信息相关的测量报告；在这个配置中，主小区组(MCG，Main Cell Group)中的所有小区认为是服务小区(serving cell)，其他小区(包括SCG中的小区)认为是邻小区。SN通过NR中的RRC消息向UE发送测量配置信息，UE向SN上报与该测量配置信息相关的测量报告；在这个配置中，SCG中的小区认为是serving cell，其他小区(包括MCG中的小区)认为是邻小区。
