Description

一种RRC状态的控制方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种无线资源控制(RRC，Radio Resource Control)状态的控制方法及装置、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)。
在5G网络环境中，为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义一个新的RRC状态，即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC连接(RRC_CONNECTED)状态。
当用户设备(UE，User Equipment)处于RRC_INACTIVE状态时，网络侧会通过专用信令给UE配置无线接入网(RAN，Radio Access Network)的寻呼区域，该RAN寻呼区域可以是一个小区或者多个小区。当UE在该区域内移动时不用通知网络侧，遵循空闲(idle)下移动性行为，即小区选择重选原则。当UE移动出RAN配置的寻呼区域时，会触发UE恢复RRC连接并重新获取RAN配置的寻呼区域。当UE有下行数据到达时，为UE 保持RAN和核心网(CN，Core Network)之间连接的基站(如gNB)会触发RAN寻呼区域内的所有小区发送寻呼消息给UE，使得INACTIVCE状态的UE能够恢复RRC连接，进行数据接收。
所以UE从INACTIVE状态进入RRC连接状态，有三种情况：
一是，UE有下行数据到达，网络侧发起RAN侧的寻呼，促使UE进入连接状态；
二是，UE自身发起RAN位置区域更新，例如周期性RAN位置更新或者跨区域位置更新；
三是，UE有上行数据发送需求，促使UE进入连接状态。
目前，网络侧对UE的RRC状态的控制缺乏灵活性，管控效率较低。

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。
以下对5G网络环境中的三种RRC状态进行说明：

2)RRC_CONNECTED状态：存在RRC连接，基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
3)RRC_INACTIVE状态：移动性为基于UE的小区选择重选，存在CN和RAN之间的连接，UE AS上下文存在某个基站上，寻呼由RAN触发，基于RAN的寻呼区域由RAN管理，网络侧知道UE的位置是基于RAN的寻呼区域级别的。
图1为RRC连接恢复过程的示意图，如图1所示，RRC连接恢复过程包括以下流程：
