Description

终端状态的获取、指示方法及装置Terminal state acquisition, indication method and device 技术领域Technical field
本发明涉及通信领域，具体而言，涉及一种终端状态的获取、指示方法及装置。The present invention relates to the field of communications, and in particular to a method and an apparatus for acquiring and indicating a terminal state.
背景技术Background technique
如图1所示，在4G(4Generation，***)或LTE(Long Term Evolution，长期演进)移动通信***中，将具有相同QoS(Quality of Service，服务质量)要求的数据流聚合成承载，接入网(Access Network，AN)与核心网(Core Network，CN)对QoS的处理都是按承载进行的。4G***中，接入网包括演进基站(evolved Node B，eNB)与用户设备(User Equipment，UE)，eNB与CN间S1接口上的网络侧承载和eNB与UE间空口上的无线承载是1:1对应的。As shown in FIG. 1 , in a 4G (4Generation, 4th Generation) or LTE (Long Term Evolution) mobile communication system, data flows with the same QoS (Quality of Service) requirements are aggregated into bearers. Access network (AN) and core network (Core Network, CN) handle QoS by bearer. In the 4G system, the access network includes an evolved Node B (eNB) and a User Equipment (UE), and the network side bearer on the S1 interface between the eNB and the CN and the radio bearer on the air interface between the eNB and the UE are 1 :1 corresponds.
如图2所示，当前正在进行的5G(5Generation，第五代)新技术研究，其目标相比4G将有1000倍级网络吞吐量、100倍级设备连接数、10倍级低时延的性能提升。在5G***中，接入网对QoS的处理仍将以承载的概念进行。但核心网对QoS的处理将采取新的机制，即采用流(Flow)的概念，核心网中的多个流可以映射到接入网中的单个承载。As shown in Figure 2, the current 5G (5Generation, 5th generation) new technology research, its target will have 1000 times network throughput, 100 times device connection number, 10 times low latency compared to 4G. Performance improvement. In a 5G system, the access network's processing of QoS will still proceed with the concept of bearer. However, the core network will adopt a new mechanism for processing QoS, that is, adopting the concept of flow, and multiple streams in the core network can be mapped to a single bearer in the access network.
5G***将采用一个统一的技术架构来支持增强移动宽带(enhanced Mobile Broadband，eMBB)、巨量机器类型通讯(massive Machine Type Communication，mMTC)、高可靠低时延通讯(Ultra Reliable and Low Latency Communication，URLLC)等业务。5G***中，核心网、基站和UE都会做重大演进。5G基站称作gNB。类似于4G***中eNB之间的X2接口，5G***中，gNB之间也可以有直接接口，称为Xn接口。类似于4G***中eNB与CN间的S1接口，在5G***中，gNB与5G CN间的接口称为NG接口。另外，5G***中很可能出现一种过渡型的基站称作eLTE eNB，它在空口上更接近于LTE eNB(即4G***的eNB)，但它可以直接通过NG接口连接到5G CN。The 5G system will adopt a unified technology architecture to support enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable low-latency communication (Ultra Reliable and Low Latency Communication). URLLC) and other services. In the 5G system, the core network, base station and UE will all undergo major evolution. A 5G base station is called a gNB. Similar to the X2 interface between eNBs in a 4G system, in a 5G system, there may also be a direct interface between the gNBs, called an Xn interface. Similar to the S1 interface between the eNB and the CN in the 4G system, in the 5G system, the interface between the gNB and the 5G CN is called an NG interface. In addition, it is likely that a transitional base station in the 5G system is called an eLTE eNB, which is closer to the LTE eNB (ie, the eNB of the 4G system) on the air interface, but it can be directly connected to the 5G CN through the NG interface.
类似于4G***中的轻连接(Light Connection)状态，5G***中也提出了非活跃(Inactive)状态。对于从连接态进入Inactive状态的UE，其在NG接口的UE上下文(UE Context)继续保留，但在空口的连接被释放。Similar to the Light Connection state in 4G systems, the Inactive state is also proposed in 5G systems. For a UE entering the Inactive state from the connected state, its UE context (UE Context) on the NG interface continues to be reserved, but the connection at the air interface is released.
一般而言，对于跨RAT的移动，处于连接态的UE采用切换，处于idle态的UE采用小区重选。然而对于处在非活跃或轻连接状态的UE在跨RAT时的移动性，目前还没有解决方案。另外，由于不同RAT的时延性能不同，5G***中的NR(New RAT)比5G***中的eLTE和4G***的LTE具有更低的时延性能，对于处在NR下的非活跃状态的UE移动到eLTE下如仍进入非活跃状态，或移动到LTE下如进入轻连接状态，则对于某些业务(如URLLC业务)，其性能将很可能无法得到满足。In general, for mobile across the RAT, the UE in the connected state adopts handover, and the UE in the idle state adopts cell reselection. However, there is currently no solution for the mobility of UEs in an inactive or lightly connected state across RATs. In addition, NR (New RAT) in 5G systems has lower latency performance than eLTE in 4G systems and LTE in 4G systems due to different delay performance of different RATs, for inactive UEs under NR If you move to eLTE and still enter the inactive state, or move to LTE and enter the light connection state, the performance of some services (such as URLLC service) may not be satisfied.
针对相关技术中，对于处于非活跃状态或轻连接状态的UE在跨RAT移动后由于无法知晓终端状态而导致的业务性能无法满足等问题，尚未提出有效的解决方案。 For the related art, an effective solution has not been proposed for a problem that the UE in an inactive state or a lightly connected state cannot satisfy the service performance due to the inability to know the state of the terminal after moving across the RAT.
