- a new UE RRC state that is, RRC INACTIVE, is defined relative to 4G LTE.
- RRC INACTIVE For a UE in RRC inactive state, it has the following characteristics:
- Mobility is achieved through cell reselection
- the control plane and user plane connection of the UE's radio access network side to core network has been established (ie, there is a user plane and control plane connection similar to LTE S1);
- At least one base station stores the context information of the access layer of the UE, that is, at least the control plane of the radio access network side to the core network (CN-NR RAN) of the UE and the base station connected to the user plane store the UE.
- Access layer context information the UE also stores context information of the access layer;

Description
本发明涉及5G无线通信技术领域,尤其涉及一种UE(User Equipment)上报信息辅助基站进行UE RRC(Radio Resource Control)状态转换的技术方案。
在5G NR(New Radio)***中,为了满足新的业务特性,并考虑UE的省电,相对比4G LTE,定义了一种新的UE RRC状态,即RRC非激活态(RRC INACTIVE)。对于处于RRC非激活状态的UE,具有以下特性:
移动性通过小区重选实现;
UE的无线接入网侧到核心网(CN-NR RAN)的控制面和用户面连接已建立(即保持有类似于LTE S1的用户面和控制面连接);
至少有一个基站储存有该UE的接入层的上下文信息,即至少保持有UE的无线接入网侧到核心网(CN-NR RAN)的控制面和用户面连接的基站储存有该UE的接入层上下文信息;UE也保存有接入层的上下文信息;
定义了网络侧通知区域,由NR RAN可以初始化给UE发送Paging(寻呼消息),因此网络侧通知区域由NRRAN(Radio Access Network,无线接入网)来管理,并且NR RAN知道UE属于哪个网络侧通知区域。
UE监听RAN paging和核心网paging;
UE需要进行RAN侧通知区域和CN(Core Network,核心网)跟踪区域更新。
因此5G有了三种RRC状态,即RRC IDLE(RRC空闲态),RRC Connected(RRC连接态),RRC Inactive(RRC非激活态),相应的RRC状态转换也变的更复杂。LTE的RRC状态只需要在RRC IDLE和RRC Connected之间相互转换,而5G的RRC状态还需要在RRC Connected和RRC Inactive之间相互转换。
当UE处于RRC Inactive和RRC Idle状态时,都可以实现UE省电,但是UE处于RRC空闲态时更省电。当UE处于RRC Inactive状态时,相比于UE处于RRC Idle状态,UE能够更快速的转换到RRC Connected态,因此Inactive UE可以减少发送数据的时延,满足不同业务的要求。UE处于RRC inactive状态时,对网络的要求更高,因为网络需要保存UE的接入层上下文和保持有该UE的无线接入网侧到核心网(CN-NR RAN)的控制面和用户面连接。
由于5G支持三种RRC状态,即RRC IDLE,RRC Connected和RRC Inactive。并且5G的RRC状态支持RRC Connected和RRC Inactive之间相互转换,RRC Idle和RRC Connected之间相互转换。对于LTE,针对每个RRC connected UE,基站会运行一个RRC非激活定时器,如果该定时器超时,则基站可以将UE转换到RRC Idle态。但是对于5G,增加了一个RRC状态即RRC Inactive,如果5G NR仍然沿用LTE的方案,只采用定时器基站仍需要确定将UE从RRC Connected状态转换到RRC Inactive还是RRC Idle状态,但是基站目前没有足够的信息来确定将UE从RRC Connected状态转换到RRC Inactive还是RRC Idle状态。

为了使本技术领域的人员更好地理解本发明中的技术方案,下面将结合本发明实施例中的附图,对本申请实施例中的技术方案进行完整地描述。
本发明技术方案提出,UE可以在RRC空闲态/非激活态到RRC连接状态转换过程中向基站上报辅助信息,RRC连接态UE可以在RRC连接态时向基站上报辅助信息。当基站需要将RRC连接态UE转换到RRC空闲态或者RRC非激活态时,基站可以根据UE之前上报的信息来协助决定将转换到RRC空闲态或者RRC非激活态。
进一步地,本发明提出,当基站需要将处于RRC连接态的UE转换到RRC空闲态或者RRC非激活态时,优先考虑基站的状态,然后根据UE上报的辅助信息来决定将UE转换到RRC空闲态或者RRC非激活态。
本发明提出了辅助信息的上报方式的设计:
RRC空闲态/非激活态UE在转换到RRC连接态的过程中,通过MSG3(随机接入消息3)或者MSG5(随机接入消息5)上报信息;
连接态UE通过RRC/MAC/PHY信令上报信息;
当基站需要将RRC连接态UE转换到RRC空闲态或者RRC非激活态时,基站根据UE上报的信息或者基站根据UE上报的信息结合基站的负载确定UE的RRC状态。
本发明进一步提出了上报内容的设计,参见以下实施例的详细说明。
实施例一
参见图1,实施例一的实现如下:
1.如果处于RRC空闲态或者RRC非激活态UE要转换到RRC连接态,则UE发起随机接入过程,包括UE发送随机接入消息1(MSG 1)和基站发送随机接入消息2(MSG 2)。
2.UE发送随机新接入消息3(MSG3),并在随机接入消息3中上报辅助信息,该辅助信息可以包括:
a.UE推荐的RRC状态,例如可以用1bit进行标识,1表示推荐RRC Inactive,0表示推荐RRC Idle;
b.UE的目标业务类型,例如UE可以上报其目标业务类型为URLLC(Ultra Reliable Low Latency Communication,高可靠低时延),eMBB(Enhance Mobile Broadband,增强移动带宽)等业务类型;
c.UE的电量,例如UE可以指示低电量;
d.UE的移动状态。
具体实施时,可以提供一项或以上信息。
进一步的,还可以附带提供其他参考信息,例如UE推荐的RRC非激活定时器时长。当RRC非激活定时器超时时,基站根据基站的状态和UE的状态来确定UE的RRC状态。
其中,如果UE是从RRC空闲态转换到RRC连接态,随机接入消息MSG3可以为RRC Connection Request(RRC连接建立请求)消息及其类似的消息;如果UE是从RRC非激活态转换到RRC连接态,随机接入消息MSG3可以为RRC Connection Resume Request(RRC连接恢复请求)消息及其类似的消息。
3.基站发送随机接入消息4(MSG4),UE发送随机接入消息5(MSG5)并成功转换到RRC连接态。
4.UE转换到RRC连接态后,如果基站需要将该UE转换到RRC空闲态或者RRC非激活态,则:
a.基站可以根据UE在MSG3上报的信息来协助基站将UE转换到RRC空闲态或者RRC非激活态;
优选地,进一步方案为,
如果UE推荐的RRC状态为RRC非激活态,则基站将UE转换到RRC非激活态,如果UE推荐的RRC状态为RRC空闲态,则基站将UE转换到RRC空闲态;
如果UE上报的目标业务类型为URLLC,则基站将UE转换到RRC非激活态,如果UE上报的目标业务类型为eMBB,则基站将UE转换到RRC空闲态;
如果UE上报电量低,则基站将UE转换到RRC空闲态,否则基站将UE转换到RRC非激活态;
如果UE上报移动速度高,则基站将UE转换到RRC空闲态,否则基站将UE转换到RRC非激活态。
进一步地,如果UE同时提供上述多种辅助信息,则基站可以随机选择以某种辅助信息作为依据进行UE的RRC状态转换,或者基站可以优先以某种辅助信息作为依据进行UE的RRC状态转换。
b.基站可以优先考虑基站的状态,再根据UE在MSG3上报的信息来确定将UE转换到RRC空闲态或者RRC非激活态;例如基站优先考虑基站的负载,如果负载较低,则根据UE上报的信息来确定将UE转换到RRC空闲态或者RRC非激活态;如果负载较高,则基站可以忽略UE上报的信息,将UE转换到RRC空闲态。具体实施时,本领域技术人员可以自行预设负载相关阈值,以便判断基站的负载是否较低或较高。
然后基站指示UE转换到RRC空闲态或者RRC非激活态,UE根据基站的指示进入RRC空闲态或者RRC非激活态。
实施例二
参见图2,实施例二的实现如下:
1.如果处于空闲态或者非激活态UE要转换到连接态,则UE发起随机接入过程,包括UE和基站之间交互传递随机接入消息1、随机接入消息2、随机接入消息3以及随机接入消息4;
2.UE发送随机接入消息5,并在随机新接入消息5(MSG5)中上报辅助信息,该信息如实施例一,可以包括:
a.UE推荐的RRC状态,例如可以用1bit进行标识,1表示推荐RRC Inactive,0表示推荐RRC Idle;
b.UE的目标业务类型,例如UE可以上报其目标业务类型为URLLC(Ultra Reliable Low Latency Communication,高可靠低时延),eMBB(Enhance Mobile Broadband,增强移动带宽)等业务类型;
c.UE的电量,例如UE可以指示低电量;
d.UE的移动状态;
具体实施时,可以提供一项或以上信息。
进一步的,还可以附带提供其他参考信息,例如UE推荐的RRC非激活定时器时长。当RRC非激活定时器超时时,基站根据基站的状态和UE的状态来确定UE的RRC状态。
其中,如果UE是RRC空闲态转换到RRC连接态,随机接入消息MSG5可以为RRC Connection Setup Complete(RRC连接建立完成)消息及其类似的消息;如果UE是RRC非激活态转换到RRC连接态,随机接入消息MSG5可以为RRC Connection Resume Complete(RRC连接恢复完成)消息及其类似的消息;
3.UE转换到RRC连接态后,如果基站需要将该UE转换到RRC空闲态或者RRC非激活态,则:
a.基站可以根据UE在MSG5上报的信息来协助基站将UE转换到RRC空闲态或者RRC非激活态;
具体的,基站可以根据如实施例一中所述方法进行UE的状态转换;
b.基站可以优先考虑基站的状态,再根据UE在MSG5上报的信息来确定将UE转换到RRC空闲态或者RRC非激活态;例如基站优先考虑基站的负载,如果负载较低,则根据UE上报的信息来确定将UE转换到RRC空闲态或者RRC非激活态;如果负载较高,则基站可以忽略UE上报的信息,将UE转换到RRC空闲态。
然后基站指示UE转换到RRC空闲态或者RRC非激活态,UE根据基站的指示进入RRC 空闲态或者RRC非激活态。
实施例三
参见图3,实施例三的实现如下:
1.当UE处于RRC连接态时,UE可以向基站上报信息,上报的信息包括实施例一中步骤1所述。
UE可以通过RRC信令,MAC层信令,物理层信令上报所述信息;
2.如果基站需要将该UE转换到RRC空闲态或者RRC非激活态,则:
a.基站可以根据UE在1中上报的信息来协助基站将UE转换到RRC空闲态或者RRC非激活态;
b.基站可以优先考虑基站的状态,再根据UE在1中上报的信息来确定将UE转换到RRC空闲态或者RRC非激活态;例如基站优先考虑基站的负载,如果负载较低,则根据UE上报的信息来确定将UE转换到RRC空闲态或者RRC非激活态;如果负载较高,则基站可以忽略UE上报的信息,将UE转换到RRC空闲态。
然后基站指示UE转换到RRC空闲态或者RRC非激活态,UE根据基站的指示进入RRC空闲态或者RRC非激活态。
具体实施时,可以采用计算机软件技术实现各流程的自动运行。也可以采用模块化方式提供相应设备。

第一辅助信息上报模块,用于处于RRC空闲态或RRC非激活态时,在RRC空闲态或RCC非激活态到RRC连接状态转换过程中向基站上报辅助信息;
