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灾难漫游方法、装置、终端、第一通信设备及第二网络进行详细地说明。
本申请各实施例针对网络侧发生灾难对终端的影响大的问题,提供一种解决方案。为了便于更加清晰地理解本申请各实施例,首先对一些相关的技术知识进行如下介绍。
一、MOCN简介。
多运营商核心网(Multi-Operator Core Network,MOCN)是指多个运营商公用一套无线网络,即同一套基站可以同时连接到多个运营商(Operator,OP)的核心网(Core Network,CN)。
图2是相关技术中MOCN的示意图,如图2所示,各运营商共享无线网络资源(小区载频),即共享无线接入网(Radio Access Network,RAN)节点,但不共享CN节点,CN节点属于不同运营商,不同运营商例如为图中运营商1(OP1)和运营商1(OP2)。
RAN节点通过系统广播消息广播支持的公用陆地移动通信网(Public Land Mobile Network,PLMN)的信息,例如PLMN标识ID。终端向RAN发起无线资源控制(Radio Resource Control,RRC)连接建立时,会向RAN提供接入哪个运营商的信息,例如携带目标运营商的PLMN ID;RAN根据该信息将终端的请求路由到对应的运营商的CN。
二、相关技术中在RAN发生灾难的时候终端是如何注册的。
步骤1、如果终端希望获取PLMN2的(RAN)灾难漫游服务,终端首先需要执行在PLMN2上的初始注册,这个初始注册具有一个特殊的注册类型:灾难漫游初始注册(Disaster Roaming Initial Registration)。
步骤2、注册的时候终端可能上报终端是从一个发生灾难条件(Disaster Condition,DC)的PLMN来的(PLMN with Disaster Condition),且这个PLMN ID是无需安全上下文的明文。
步骤3、接入和移动管理(Access and Mobility Management Function,AMF)在收到注册消息后,根据终端提供的PLMN ID或者用户隐藏标识符(Subscription Concealed Identifier,SUCI)或全局唯一临时标识(Globally Unique Temporary Identity,5G-GUTI)推导出来的PLMN ID是发生DC的,由AMF判断是否可以提供灾难漫游服务。如果没发生DC,或者无法提供灾难漫游,AMF用合适的原因值拒绝终端。
步骤4、AMF通过以后,网络需要对终端进行鉴权(authentication)。可选地,AMF向鉴权服务功能(Authentication Server Function,AUSF)提供一个指示信息,用于指示终端正在进行灾难漫游服务,如果提供了,AUSF也会向统一数据管理(Unified Data Management,UDM)提供这个指示信息。
步骤5,鉴权通过以后,AMF可能提供一个终端在进行DC漫游的指示信息,UDM根据这个指示信息为AMF提供终端相应的签约数据。
步骤6,AMF接受终端的注册请求,并在响应消息中限定终端的注册区域(Registration Area,RA),仅局限于发生DC的区域;此外AMF可能给终端提供一个新的PLMN列表(List)以及灾难范围(disaster range),用于在此PLMN发生DC时,终端确定支持灾难漫游服务的PLMN。
三、5G中的加密和完保机制。
1、终端的所有NAS消息大多都必须通过完整性保护的检测,否则终端需要丢弃这条消息,即使安全上下文已经建立了。所以完保是最重要的。
2、安全上下文通过主鉴权和密钥协商(Key agreement)过程建立,在非接入层(Non-Access Stratum,NAS)安全模式命令SMC(Security Mode Command,SMC)过程之后启用。
3、如果终端没有安全上下文,首先要用初始注册消息与AMF建立安全上下文,在启用安全上下文后,即完成NAS SMC过程,要发明文或非明文消息,都是整个放在SMC的完成(complete)消息中发给AMF。
4、用什么加密参数完全取决于AMF的网络配置,这意味着,不同PLMN之间的加密方式肯定是不同的。
四、MOCN共享场景下,如何支持终端进行灾难漫游,是亟待解决的问题。
五、异网漫游场景下,如何支持终端进行灾难漫游,是亟需解决的问题。
本申请实施例提供的灾难漫游方法,可应用于由于网络侧发生灾难而无法被服务的终端。

一、第一网络发生CN灾难时,终端获取来自第一通信设备的第一信息,终端到第二网络中执行灾难漫游注册。
下面以第一通信设备为共享(Shared)RAN、第一网络为PLMN1CN、第二网络为PLMN2CN为例进行说明。
图8是本申请实施例提供的灾难漫游方法的信令交互图之三,如图8所示,该方法包括步骤801至步骤805;其中:
步骤801、终端在PLMN1中获取服务,或者在PLMN1中注册后处于空闲(IDLE)态,或者终端仅驻留在属于PLMN1的小区中。本申请实施例不对终端是否在PLMN1中注册进行限定。
步骤802、PLMN1发生CN灾难。
具体地,PLMN1无法继续服务终端,例如PLMN1发生CN灾难。因为PLMN1发生灾难,所以PLMN1的用户在此都转为连接管理空闲(CM-IDLE)态。
步骤803、Shared RAN获知PLMN1发生CN灾难。
步骤804、Shared RAN向终端发送第一信息。
可选地,第一信息可以包括:
1、第一指示信息,用于终端确定第一网络无法服务所述终端;
2、第二指示信息,用于终端确定接入第二网络(PLMN2);
3、第四指示信息,用于请求所述终端本地去注册所述第一网络;
4、第六指示信息,用于终端确定进入空闲态。
需要说明的是,第六指示信息可以结合其他指示信息一起使用。
可选地,第一信息可以通过以下至少一项发送:RRC重配消息;RRC释放消息;系统广播消息。
可选地,第一信息可以是原因值。
可选地,第一信息还包括:PLMN2ID。
可选地,终端在获取第一信息后,可以释放与第一网络(PLMN1)的通信资源、释放与Shared RAN的通信资源。
步骤805、终端向PLMN2发送注册请求消息。
具体地,终端通过注册类型为Disaster Roaming Initial Registration的初始注册,向PLMN2发送与灾难漫游有关的注册请求。
二、第一网络发生CN灾难时,终端获取来自第一通信设备的第一信息,终端到第二网络中执行互操作过程。
下面以第一通信设备为Shared RAN、第一网络为PLMN1 5GS、第二网络为PLMN2EPS为例进行说明。
图9是本申请实施例提供的灾难漫游方法的信令交互图之四,如图9所示,该方法包括步骤901至步骤905;其中:
步骤901、终端在PLMN1中获取服务,或者在PLMN1中注册后处于IDLE态,或者终端仅驻留在属于PLMN1的小区中。本申请实施例不对终端是否在PLMN1中注册进行限定。
步骤902、PLMN1发生CN灾难。
具体地,PLMN1无法继续服务终端,例如PLMN1发生CN灾难。因为PLMN1发生灾难,所以PLMN1的用户在此都转为CM-IDLE态。
步骤903、Shared RAN获知PLMN1发生CN灾难。
步骤904、Shared RAN向终端发送第一信息。
可选地,第一信息可以包括:
1、第二指示信息,用于终端确定接入第二网络(EPS);
2、第五指示信息,用于终端确定执行切换或互操作过程;
3、第六指示信息,用于终端确定进入空闲态。
需要说明的是,第六指示信息可以结合其他指示信息一起使用。
可选地,第一信息可以通过以下至少一项发送:RRC重配消息;RRC释放消息;系统广播消息。
可选地,第一信息可以是原因值。
可选地,第一信息还包括:PLMN2ID。
步骤905、终端对PLMN2执行互操作过程或执行注册过程。
具体地,步骤905可以分为以下两种情况:
情况1、终端对PLMN2执行互操作过程,具体是终端执行第一网络到第二网络的互操作过程,前提是互操作过程涉及到的网元都没有发生灾难,互操作过程涉及到的网元例如为AMF,SMF,PCF,UPF,UDM。
可选地,终端执行第一网络到第二网络的互操作过程包括:终端向第二网络发送以下至少一项:
a.第一网络的ID;
b.终端的ID;
c.第七指示信息,用于指示第一网络无法继续服务所述终端。
情况2、终端对PLMN2执行注册过程。
可选地,终端可以向PLMN2发送注册请求消息,其中,注册请求消息可以包括以下至少一项:
a.注册类型,用于指示终端执行与灾难条件有关的注册;
b.第一网络的ID;
c.终端的ID;
d.第七指示信息,用于指示第一网络无法继续服务所述终端。
可选地,在步骤905之后,终端可以通过第二网络发去注册消息,或者发UCU且附带一个指示信息(indication)指示re-registration required,来获知第一网络的CN灾难结束,对于UCU+indication,网络侧在收到终端的注册请求消息后,拒绝终端的注册请求,并发送第八指示信息,第八指示信息可以是一个原因值,第八指示信息用于指示第一网络可以服务终端。
三、第一网络发生CN灾难时,终端可以获取来自RAN的第一信息,所述第一信息用于指示终端发送初始NAS消息,执行初始注册、重注册等等操作。
可选地,RAN还可以给终端指示PLMN2ID,此时终端可以不执行网络选择。
可选地,终端可以释放与PLMN1的网络资源。
需要说明的是,本申请实施例中网络资源例如为N1频段的资源、空口资源、RRC资源、SRB、DRB等。
可选地,如果终端可以继续使用当前RAN节点,在释放终端和当前RAN节点之间的通信资源之后,与终端再重新建立通信资源。
四、第一网络发生CN灾难时,终端可以获取来自RAN的第一信息,所述第一信息用于指示终端执行5GS到EPS的互操作过程。
可选地,第一信息可以携带EPS ID。
可选地,终端可以执行互操作过程,并携带PLMN ID,5G-GUTI和/或灾难漫游指示。
五、可以把R17机制搬到EPS中,第一网络发生CN灾难时,终端获取来自第二网络的基站(eNodeB)的广播信息。
可选地,广播信息可以携带特殊注册类型,携带标识等。
MOCN场景下的注册流程是没有区别的,但是,因为需求要求终端不执行网络选择,因此,Phase2的一个重要增强应该是:
终端获取来自RAN的指示信息(第一信息),第一信息用于指示终端发送初始NAS消息。第一信息可以是原因值,也可以是一个比特指示,广播消息,SIB消息,RRC消息等。
还需要说明的是,在异网漫游的架构下,终端需要从PLMN1的5GS转移到PLMN1的EPS。异网漫游的做法是PLMN1生成一个新的PLMN ID,这个PLMN ID是终端的EPLMN,所以在终端看来其实是接入了一个等价的PLMN。因此,旧的PLMN对应的EPS在这个新的PLMN ID看来,就是一个禁止(forbidden)PLMN,从这个角度上看,从运营商1的5GS到运营商1的EPS是符合MINT的要求的。
这里面与R17MINT有很大的区别:
区别1:
R17仅研究5GS之间支持MINT,不涉及EPS。也就是EPS的基站不会广播相关信息,终端也不会接入到forbidden PLMN的EPS中。此外,由于EPS已经商用,所以,对于EPS越小的改动肯定越好。
区别2:
R17的方式是通过初始注册,如果终端用R17的方法去接入EPS,那么EPS需要增强一个新的注册类型,新的disaster随机数,EPS的eNodeB需要广播相应信息等,会对EPS造成巨大的改动。
虽然PLMN1的EPS对于终端而言可以视为forbidden PLMN,但是从实际上看,PLMN1的EPS与PLMN1的5GS都属于同一个运营商,EPS与5GS之间都有N26接口,可以执行有N26接口的互操作,直接把终端从5GS转移到EPS,不需要终端重新注册EPS。
另一方面,如果5GS中执行互操作的网络功能(Network Functions,NF)发生灾难,那么,即使终端需要重新在EPS注册,最好的方案应该是终端基于5GS或5G无线接入网(NG Radio Access Network,NG-RAN)的指示,让终端去EPS注册,不要带新的注册类型。
还需要说明的是,终端是PLMN1的终端,终端和PLMN2完全没有安全上下文,那么一方面终端既不可能收到PLMN2发来的消息,因为要么终端无法解密出PLMN2的消息,要么整个消息直接就被终端丢弃了;另一方面PLMN1的消息通过RAN转发给PLMN2,PLMN2也不能识别,因为每个PLMN的加密方式是不同的。
终端和网络侧,无论谁给谁发消息,都是无法解密的。如果发明文,也会被对方丢弃,因为标准中规定了SMC之后,所有的NAS消息都需要完保和加密。
可以理解的是,本申请实施例研究的是OP1发生CN灾难时,终端如何转移到OP2中使用OP2提供的灾难漫游服务。
