Description

一种小区重选方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种小区重选方法及装置、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，5 th 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。当然，NR小区也可以独立部署。
在NR讨论中，每个NR载波的最大信道带宽，对于低频是100MHz，对于高频是400MHz，且100MHz/400MHz的信道带宽是连续的。如果终端设备(UE，User Equipment)保持工作在宽带载波上，则UE的功率消耗是很大的，因此，建议UE的射频(RF，Radio Frequency)带宽可以根据UE实际的吞吐量来调整。
UE在空闲(idle)状态下执行小区选择和小区重选的过程中，为了满足idle下的负荷均衡，定义了基于频率优先级的小区重选策略。在同频小区中或者同一优先级的异频小区中，采用R准则进行小区重选，即：按照小区的信号质量进行排序，选择信号质量最好的小区为候选的重选目标小区。对于高频率优先级的小区，只要该小区信号质量满足一定门限，就重选到高频率优先级的小区中；对于低频率优先级的小区，只有当服务小区的信号质量低于一定门限时才会重选到低频率优先级的小区。在NR小区中，基于频率优先级进行小区重选同样可以采用。
在LTE小区中，如果当前LTE小区支持LTE和NR之间做LTE-NR双连接(LTE-NR DC，LTE-NR Dual Connection)，则此时LTE小区通过其系统消息(如SIB2)会广播5G指示信息，当UE读取到该5G指示信息时，会屏显5G信号。
在eLTE小区中，演进节点B(eNB，evolved Node B)可以连接到4G核心网(如演进分组核心网(EPC，Evolved Packet Core))和5G核心网(5G CN，5G Core Network)，此时系统消息会广播eNB连接的核心网是EPC，或5G CN，或EPC和5G CN。
基于此，如果UE驻留在LTE小区(以同频部署为例)中，则所有的LTE小区具有相同的频率优先级，按照R准则进行小区重选的过程，即：广播5G指示信息的LTE小区(以下称为支持5G指示信息的LTE小区)和eLTE小区具有相同的重选优先级，按照信号质量进行小区重选。然而，对于支持5G指示信息的LTE小区和eLTE小区，可能运营商更希望UE优先驻留在支持某类功能的小区中去，如何满足运营商运营需求进行小区重选是有待解决的问题。
