具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而 不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
为了便于理解本申请的实施例,下面介绍以下技术点:
1.关于NTN(Non-terrestrial networks,非地面网络)简介
典型的NTN部署场景如图1所示。在相关技术中,终端(比如,用户设备(User Equipment,UE))、网关(或基站)以及核心网设备均部署在地面上,终端和网络设备之间的通信数据经由空中卫星进行中转。相对于地面通信(terrestrial networks,TN)系统,基于卫星的非地面通信系统具有更为广阔的覆盖范围,并且NTN小区服务的用户数量也会远大于TN小区。
如图1所示,UE和卫星之间的链路称为服务链路(service link),卫星和基站之间的链路称为馈线链路(feeder link)。在某些场景下(如低轨卫星(Low Earth Orbit,LEO)),由于卫星移动,会发生服务链路和/或馈线链路的切换。对于服务链路切换,小区内的所有UE的服务卫星需要从一颗卫星切换为另外一颗卫星。对于馈线链路切换,某一卫星需要从一个网关(或基站)切换到另外一个网关(或基站)。在相关技术中,无论是服务链路切换还是馈线链路切换场景,对于NTN小区的所有UE来说,都需要执行小区切换过程。
本申请涉及的终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)、智能家居(具有 无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(Personal Computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。除了上述终端设备,本申请涉及的终端也可以是终端内的芯片,例如调制解调器(Modem)芯片,系统级芯片(System on Chip,SoC)。需要说明的是,在本申请实施例并不限定终端的具体类型。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的切换处理方法、装置、通信设备及可读存储介质进行详细地说明。
参见图2,本申请实施例提供一种切换处理方法,应用于终端,具体步骤包括:步骤201。
步骤201:在源节点提供切换辅助信息的情况下,终端基于接入层AS安全状态处理所述切换辅助信息;
其中,所述切换辅助信息包括目标小区配置信息和切换触发事件信息中的至少一项,所述切换辅助信息用于辅助所述终端执行切换过程。
可选地,目标小区配置信息包括但不限于目标小区的资源配置(如随机资源配置)、目标小区的位置等。另外需要说明的是,上述目标小区配置信息可以是小区的公共配置信息(例如ServingCellConfigCommon),切换到该目标小区的定时器配置信息等。
在一些实施例中,在源节点提供切换辅助信息的情况下,可以被理解为终端直接或间接地接收到来自源节点的切换辅助信息。
可选地,切换触发事件信息包括但不限于时间事件,位置事件等。
可选地,接入层AS安全状态包括但不限于AS安全未激活或AS安全已激活。
本申请涉及的节点可以包括卫星或无人机系统,即源节点可以是源卫星,目标节点可以是目标卫星,或者源节点可以是源无人机系统,目标节点可以是目标无人机系统。
在本申请的一种实施方式中,所述切换辅助信息是通过广播或组播方式提供的,即源节点可以通过广播或组播方式向终端提供切换辅助信息,可以理解的是,切换辅助信息用于辅助源服务小区内的一个或多个终端从源服务小区切换到目标小区,其中源服务小区为源节点管理的小区。
由于NTN小区服务的覆盖范围远大于地面网络(Terrestrial Networks,TN)小区,进而服务的用户数量也会更多。又由于目前用于切换的参数都是由网络侧一对一提供给UE的,因此,频繁的切换会产生大量的系统信令开销,而在本申请的实施例中切换辅助信息是源节点通过广播或组播方式向终端提供,这样可以节省系统信令开销。具体的,由于多个终端可能需要从源服务小区切换到相同的目标小区,因此通过广播或组播方式提供切换辅助信息,可以减少相同信息的发送多次,进而有效减少系统信令开销。
可选地,AS安全状态,即AS的安全状态,可以包括激活状态和未激活状态。
在本申请的一种实施方式中,所述终端基于AS安全状态处理所述切换辅助信息包括 以下一项或多项:

(2)在所述终端的AS安全已激活的情况下,所述终端接收所述切换辅助信息;
也就是,在终端的AS安全激活之后,终端接收切换辅助信息。
(3)在所述终端的AS安全未激活的情况下,所述终端不应用所述切换辅助信息;
也就是,在终端的AS安全激活之前,终端不应用所述切换辅助信息。可以理解的,在终端的AS安全激活之前,终端可以接收所述切换辅助信息,但是终端不会应用所述切换辅助信息。
(4)在所述终端的AS安全已激活的情况下,所述终端应用所述切换辅助信息;
也就是,在终端的AS安全激活之后,终端应用所述切换辅助信息。可以理解的,在终端的AS安全激活之前,终端可以接收所述切换辅助信息,但是终端不会应用所述切换辅助信息。而在终端的AS安全激活之后,终端可以应用所述切换辅助信息。
(5)在接收到第一指示信息的情况下,所述终端应用所述切换辅助信息;其中,所述第一指示信息用于指示(或配置)所述终端基于所述切换辅助信息执行切换过程。
可选地,第一指示信息是在终端的AS安全已激活的情况下接收到的。
在本申请的一种实施方式中,所述终端基于AS安全状态处理所述切换辅助信息包括以下一项或多项:(1)在所述终端的AS安全已激活的情况下,所述终端基于所述切换辅助信息执行切换过程;(2)在所述终端的AS安全未激活的情况下,所述终端基于所述切换辅助信息执行小区选择或重选过程。
在本申请的一种实施方式中,所述终端基于所述切换辅助信息执行小区选择或重选过程包括:

其中,所述第三指示信息用于指示目标小区与所述终端的源服务小区归属于相同的网络节点或不归属于相同的网络节点。

在本申请的一种实施方式中,所述目标节点响应所述RRC重建过程包括以下一项或多项:(1)所述目标节点向所述终端发送第四指示信息,所述第四指示信息用于指示所述终端回退到RRC连接建立过程;(2)所述目标节点不发起终端上下文提取过程;(3)在所述终端通过所述RRC重建过程向所述目标节点提供安全验证参数的情况下,所述目标节点忽略所述安全验证参数。
可选地,安全验证参数包括但不限于短的媒体接入控制标识(short MAC-I)。

需要说明的是,通过RRC连接重建原因信息,目标节点可以识别该RRC连接重建过程是终端AS安全未激活的情况下发起的,因此可以区别于常规的RRC重建过程,即网 络侧无需向终端的源节点发起提取终端上下文的请求。在此情况下,目标节点指示终端回退到RRC连接建立过程,进而使得终端发起后续过程以在目标节点建立上下文。
在本申请实施例中,目标节点响应终端在AS安全未激活的情况下发起的RRC重建过程,可以避免终端回退到空闲态,从而避免了终端状态转换,简化了终端行为。
为了便于理解本申请的实施方式,下面结合实施例1进行介绍。
