Description

小区重选方法、切片组信息处理方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2022年01月07日在中国提交的中国专利申请号No.202210016586.5的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其是指一种小区重选方法、切片组信息处理方法、终端及网络侧设备。
背景技术
网络切片是一种面向业务的资源封装概念,一种网络切片通过网络切片选择辅助信息(Network Slice Selection Assistant Identity,NSSAI)唯一标示,同时也对应着一种类型的资源配置。切片注册过程中,终端请求注册的NSSAI信息(Request NSSAI)通过消息5携带到接入网侧,且约束终端一次最多只能注册8个单个NSSAI(Single NSSAI,S-NSSAI)信息;核心网根据终端签约信息、终端的Request NSSAI、本地支持的切片信息以及本地策略生成终端的允许的NSSAI(Allowed NSSAI)以及拒绝的NSSAI(Rejected NSSAI)。
终端也会预配置或者从核心网获取已配置的NSSAI(Configured NSSAI),该配置是PLMN唯一的,如果终端配置的某一PLMN没有配置Configured NSSAI,则使用默认NSSAI(Default NSSAI)信息。
在以切片为基础的小区重选的频点优先级的定义中,考虑到安全以及信令开销等问题,引入切片组的概念。网络侧会通过非接入层(Non-Access Stratum,NAS)消息,即一种加密方式通知终端切片与切片组的映射关系。然后,网络侧再以广播方式(非加密方式)通知服务小区支持的切片组信息,以及切片组在不同频率上的优先级等。
目前切片组定义的有效范围是在一个跟踪区(Tracking Area,TA)内有效。不同的TA内,切片组与切片映射关系可能不同。例如,TA0中切片组0定义是切片1,切片2;TA1中切片组0’定义是切片1,切片2,切片3;TA2 中切片组0”定义是切片0,切片2。当终端处于TA边界时,终端无法获取相邻TA的切片组信息,且由于不同TA的切片组定义可能不一致,导致终端无法基于服务TA的切片组信息执行小区重选过程。

在本公开的至少一个实施例中,所述步骤201包括:
终端接收网络侧设备发送的注册接受消息,所述注册接受消息携带所述切片组信息。

步骤6,终端反馈注册成功消息。
步骤7,终端根据获得的切片组信息,在需要进行小区重选的情况下执行基于切片的小区重选。
例如,终端选择优先级最高的切片组;终端根据选择的切片组信息,确 定支持所述切片组的载波,这里定义为第一载波列表,并将所述第一载波列表上的载波优先级分配为该切片组在这个载波上的优先级;终端按照载波优先级,对载波优先级更高的载波执行测量,并在该载波上选择信号质量最高的小区,第一小区;如果所述第一小区支持终端选择的所述第一切片组,那么终端将重选到所述第一小区;否则终端将执行所述第一载波列表上其他频率的测量,以及小区重新过程。
在本公开的另一个可选实施例中,步骤201包括:
终端接收网络侧设备发送的广播消息,所述广播消息携带所述切片组信息。
可选地,该网络侧设备为终端的服务小区。即服务小区获取到邻区支持的切片信息或切片组信息,将切片信息映射为服务小区上的切片组信息,或者,在邻区与服务小区的切片组定义不一致的情况下,将切片组信息重映射为服务小区上的切片组信息,或者,在邻区与服务小区的切片组定义一致的情况下,确定邻区支持的切片组信息;进一步的,服务小区发送广播消息,广播消息携带映射或重映射得到的切片组信息。
在本公开的另一个可选实施例中,步骤202包括:
终端根据所述切片组信息以及切片组优先级信息,进行小区重选。

终端根据所述第一切片组进行测量并根据测量结果进行小区重选。
其中,所述终端根据所述第一切片组进行测量并根据测量结果进行小区重选之前,所述方法还包括:
终端确定所述第一切片组在各个频率上的优先级信息。
相应的,所述终端根据所述第一切片组进行测量并根据测量结果进行小区重选,包括:
终端根据所述第一切片组在各个频率上的优先级,在优先级最高的频率上进行测量并根据测量结果进行小区重选;若优先级最高的频率上没有满足条件的小区则按照优先级从高到低的顺序在对应的频率上进行测量直到完成小区重选。
可选地,所述终端确定所述第一切片组在各个频率上的优先级信息,包括:
终端根据邻区的归属TA上的切片组优先级信息,或者,服务TA上的切片组优先级信息,或者,邻区的归属TA上的切片组优先级信息和服务TA上的切片组优先级信息中的最高优先级信息,对所述第一切片组在各个频率上的优先级进行赋值。
示例二,终端进行小区重选
终端获取邻区所属的TA,邻区所属TA的获取方式包括终端读取邻区的广播消息获取邻区的跟踪区域码(tracking area code,TAC),或服务小区广播邻区所属的TA。例如,终端在Cell 1上驻留的时候,读取Cell 2广播消息,获取Cell 2所属的TA;或者终端读取Cell 1的广播消息,Cell1上广播邻区Cell 2所属的TA。从而终端可以获取Cell 2属于TA3。
终端选择优先级最高的切片组(即第一切片组),例如终端支持Slice A,Slice B,Slice C。其中优先级最高的Slice是Slice A。假设Slice A在TA2映射到Slice组1,在TA3映射到Slice组2’.
终端确定周围邻区后,分配第一切片组在不同频率(也可以称为不同频率,如F1,F2)上的优先级。有以下3种方案:
方案1:终端确定Cell2属于TA3,那么将按照TA3的优先级进行赋值。例如,将第一切片组在F1上的优先级设置为6,将第一切片组在F2上的优先级设置为3,那么F1优先级更高,那么只要F1上有满足条件的小区终端将驻留在F1上的小区,否则终端将检测F2。
方案2:终端无法确定Cell2的TA,那么终端按照服务TA的优先级进行 赋值。例如这里终端能够获取切片组在TA2中的载波优先级分别为F1为5,F2为3,那么将第一切片组在F1上的优先级设置为5,将第一切片组在F2上的优先级设置为3,那么F1优先级更高,那么只要F1上有满足条件的小区终端将驻留在F1上的小区,否则终端将检测F2。
方案3:终端无法确定Cell2的TA。终端将分别根据TA2的切片组频率优先级和TA3的切片组频率优先级的最大值进行赋值,例如,将第一切片组在F1上的优先级设置为6,将第一切片组在F2上的优先级设置为3,那么F1优先级更高,那么只要F1上有满足条件的小区终端将驻留在F1上的小区,否则终端将检测F2。
综上,本公开实施例中终端预先获取到服务TA支持的切片组信息,注册区RA包括的至少两个TA支持的切片组信息,RA的至少一个相邻TA支持的切片组信息,邻区支持的服务小区切片组信息,邻区支持的切片组信息中的至少一项,在需要执行小区重选的情况下根据获取到的切片组信息和切片组优先级信息,进行小区重选;能够解决由于切片组在不同TA定义不同且终端无法获取其他TA的切片组信息导致的无法执行小区重选的问题。

可选地,如图4所示,终端的服务小区为小区1(Cell 1),邻区为Cell 2;则终端获取的切片组信息包括:Cell 2支持的切片组信息(在邻区与服务小区的切片组定义一致的情况下),或者,Cell 2支持的Cell 1的切片组信息(在邻区与服务小区的切片组定义不一致的情况下)。
在本公开的至少一个实施例中,步骤501包括:
网络侧设备根据终端的注册请求消息,向终端发送注册接受消息,所述注册接受消息携带所述切片组信息。换言之,终端在注册时获取切片组信息。
可选地,该网络侧设备为核心网网元,如AMF。例如,网络侧设备向终端回复注册接受消息(Registration accept)。其中,注册接受消息携带切片组信息可以包括以下至少一项:

当前注册区(Registration Area,RA)的内部分或全部TA的切片组信息,包括切片(slice)与切片组的映射关系;如图3所示,AMF可以给终端发送整个RA内所有TA的切片组信息,包括TA0-TA2;
当前RA相邻的TA中的切片组信息,例如TA3中的切片组信息等。可选地,AMF可以通过终端的移动轨迹或布网信息或终端历史信息(包括驻留过的RA/TA等信息),判断将哪个相邻TA的切片组信息发送给终端。
在本公开的又一个可选实施例,步骤501包括:
网络侧设备发送广播消息,所述广播消息携带所述切片组信息。
可选地,该网络侧设备为终端的服务小区。即服务小区获取到邻区支持的切片信息或切片组信息,将切片信息映射为服务小区上的切片组信息,或者,在邻区与服务小区的切片组定义不一致的情况下,将切片组信息重映射为服务小区上的切片组信息,或者,在邻区与服务小区的切片组定义一致的情况下,确定邻区支持的切片组信息;进一步的,服务小区发送广播消息,广播消息携带映射或重映射得到的切片组信息。
作为一个可选实施例,在所述切片组信息包括:服务小区的邻区支持的服务小区切片组信息的情况下,所述方法还包括:
网络侧设备通过Xn接口或NG接口获取邻区支持的切片信息或邻区支持的邻区切片组信息;
网络侧设备将邻区支持的切片信息映射为服务小区切片组,得到所述邻区支持的服务小区切片组信息;或者,网络侧设备对邻区支持的邻区切片组信息进行重映射,得到所述邻区支持的服务小区切片组信息。
可选地,通过Xn接口获取邻区支持的切片信息或邻区支持的邻区切片组信息,包括通过Xn建立过程以及RAN节点重配置更新过程,获取邻区支持的切片信息或邻区支持的邻区切片组信息。
可选地,通过核心网获取邻区支持的切片信息或邻区支持的邻区切片组信息,包括NG(RAN与AMF之间接口)建立过程获取邻区支持的切片信息或邻区支持的邻区切片组信息。
例如,如图4所示,终端的服务小区为小区1(Cell 1),邻区为Cell 2。假定Cell1支持切片组分别为:切片组1:切片1,切片2;切片组2:切片4,切片5。而Cell1获取到的Cell2支持的切片为切片1,切片2,切片3;那么Cell1可以将Cell2支持切片1和切片2,映射为Cell1的切片组1。则服务小区在广播消息通知的时候,通知为:Cell2支持切片组1,其中切片组1的定义是按照Cell1定义的,Cell1和Cell2分别属于不同的TA。
再例如,如图4所示,终端的服务小区为小区1(Cell 1),邻区为Cell 2。。假定Cell1支持切片组分别为:切片组1:切片1,切片2;切片组2:切片4,切片5。而Cell1获取到的Cell2支持的切片组信息为:切片组3:切片1,切片2,切片3;那么Cell1可以将Cell2支持切片组3,映射为Cell1的切片组1;则服务小区在广播消息通知的时候,通知为:Cell2支持Cell1的切片组1。
在本公开的至少一个实施例中,所述方法还包括:
向终端发送非接入层NAS消息或广播消息,NAS消息或广播消息携带各个TA上的切片组优先级信息;所述切片组优先级信息包括:切片组在各个频率上的优先级信息。
综上,本公开实施例中终端预先获取到服务TA支持的切片组信息,注册区RA包括的至少两个TA支持的切片组信息,RA的至少一个相邻TA支持的切片组信息,邻区支持的服务小区切片组信息,邻区支持的切片组信息 中的至少一项,在需要执行小区重选的情况下根据获取到的切片组信息和切片组优先级信息,进行小区重选;能够解决由于切片组在不同TA定义不同且终端无法获取其他TA的切片组信息导致的无法执行小区重选的问题。
为了更清楚的描述本公开实施例提供的小区重选方法,下面结合一个示例进行说明。
示例三,终端根据获取的切片组信息执行小区重选
如图7所示,当终端在RA1进行注册时,终端获取了中相邻TA3的切片组信息,并存储。假定目前终端驻留在Cell1,Cell1在TA2,属于RA1。当终端移动到TA2边界时,终端可以通过测量获取到周围的邻频信息。当Cell1上的S准则不能被满足时或终端由连接态进入到空闲态或非激活(INACTIVE)态时,例如Cell1上的信号质量低于预设门限时,终端执行小区重选。
终端确定存储的切片组信息,以及切片组优先级信息(终端通过广播消息获取或通过NAS消息获取),邻区支持的切片组信息或邻区支持的服务小区的切片组信息。如果邻区与服务小区属于不同的TA,服务小区还需要通知邻区支持服务小区的切片组信息。
例如,切片组信息如下:
在TA2中:
切片组1对应的切片分别是切片A,切片B;
切片组2对应的切片分别是切片E,切片F;
在TA3中:
切片组1’对应的切片分别是切片E,切片F,切片G;
切片组2’对应的切片分别是切片A,切片B,切片C。
切片组优先级信息如下:
在TA2上的优先级顺序如表1所示:
表1
  F1 F2
切片组1 5 3
切片组2 4 1
在TA3上的优先级顺序如表2所示:
表2
  F1 F2
切片组1’ 4 2
切片组2’ 6 3
当邻区与服务小区的切片组定义是一致时,那么广播消息广播内容是:Cell2支持的切片组信息为切片组1(可以不用区分是Cell1还是Cell2)。
当邻区与服务小区的切片组定义是不一致时,那么广播消息广播的内容是:Cell2支持Cell1上的切片组1(实际对应的是Cell2上切片组2’),以及切片组1在不同TA上的频率优先级。
终端根据不同TA上的切片组的优先级执行小区重选。
例如,如表1所示,终端能够获取TA1范围内切片组1在F1上的优先级为5,如表2所示,TA2范围切片组1(对应Slice2组2’)在F1上的优先级为6(表格中标黄部分)。终端在执行小区重选时,将考虑切片组1的上述两个优先级,执行后续的小区重选。
本公开实施例中终端预先获取到服务TA支持的切片组信息,注册区RA包括的至少两个TA支持的切片组信息,RA的至少一个相邻TA支持的切片组信息,邻区支持的服务小区切片组信息,邻区支持的切片组信息中的至少一项,在需要执行小区重选的情况下根据获取到的切片组信息和切片组优先级信息,进行小区重选;能够解决由于切片组在不同TA定义不同且终端无法获取其他TA的切片组信息导致的无法执行小区重选的问题。
