通信方法、装置及系统
相关申请的交叉引用
本申请要求在2020年06月22日提交中国专利局、申请号为202010573251.4、申请名称为“通信方法、装置及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及通信方法、装置及系统。
背景技术
多运营商核心网(Multi-Operator Core Network,MOCN),即一套无线网络可以同时连接到多个运营商的核心网节点,可实现多家运营商共享同一套无线网络。
MOCN的特点包括:1)各运营商不共享核心网节点;2)各运营商共享无线网络资源,如共享小区、共享小区频点;其中,共享小区频点可以是由各个运营商提供一部分或全部频点作为共享资源;3)接入网设备在共享小区内广播发送参与共享的所有运营商的公共陆地移动网络(public land mobile network,PLMN)标识,该共享小区中的终端设备将由接入网设备路由到各自签约的运营商的核心网。
基于MOCN的共享方式,可以极大提高了频谱、设备、传输、网管等共享程度,最大程度降低运营商成本,提升了网络资源利用率。
然而,在基于MOCN的共享方式中,不用运营商之间如何进行费用清算,目前还没有相应的方案。

本申请中的会话管理网元、接入网设备、移动性管理网元、计费网元分别可以是图2(a)或图2(b)中的SMF、RAN、AMF、CHF,也可以是未来通信如第六代(6th generation,6G)网络中具有上述SMF、RAN、AMF、CHF的功能的网元,本申请对此不限定。为方便说明,本申请以会话管理网元、接入网设备、移动性管理网元、计费网元分别为上述SMF、RAN、AMF、CHF为例进行说明。
为解决背景技术提到的问题,基于图2(a)或图2(b)所示的网络架构,如图3(a)所示,本申请提供一种通信方法。该通信方法是基于PLMN粒度或基于终端设备粒度统计第一PLMN对于第二PLMN的资源的使用情况。
其中,RAN是由第一PLMN和第二PLMN进行共享,也即第一PLMN和第二PLMN分别提供一些资源(如频点、带宽等频谱资源),然后双方对这些资源进行共享使用。RAN下的归属于第一PLMN的终端设备(也即签约第一PLMN的终端设备)可以使用共享资源中的第一PLMN的资源,或共享资源中的第二PLMN的资源,同样的,RAN下的归属于第二PLMN的终端设备(也即签约第二PLMN的终端设备)也可以使用共享资源中的第二PLMN的资源,或共享资源中的第一PLMN的资源。
该方法包括以下步骤:
步骤301a,RAN生成统计信息。
所述统计信息用于指示RAN下的归属于第一PLMN的至少一个终端设备对RAN上的第二PLMN的资源的使用情况。
本申请任意实施例中,RAN生成的统计信息也可以称为计费信息,或者称为用于计费的信息,或者称为计费参数等。
步骤302a,RAN向AMF发送统计信息。相应地,AMF可以接收到该统计信息。
AMF可以向归属于第二PLMN的CHF发送该统计信息,或者是AMF向SMF发送该统计信息,然后由SMF将统计信息发送至归属于第二PLMN的CHF。从而,CHF可以根据该统计信息对第一PLMN进行计费。
基于上述方案,可以实现共享同一接入网设备的不同PLMN之间的相互计费,有助于实现费用的精确计算。
作为一种实现方法,上述步骤301a中,RAN可以基于PLMN粒度进行计费,也即RAN统计归属于第一PLMN的所有终端设备对RAN上的第二PLMN的资源的使用情况,从而生成PLMN粒度的统计信息,则上述步骤302a中,RAN可以通过AMF、SMF将PLMN粒度的统计信息发送至计费网元,或者RAN通过AMF将PLMN粒度的统计信息发送至计费网元。其中,RAN向AMF发送统计信息时,可以将统计信息携带于节点级信令或终端设备级信令中发送至AMF。这里的节点级信令指的是RAN与AMF之间的信令,不与具体的终端设备关联。而终端设备级信令指的是某个具体的终端设备的信令,与该终端设备有关。
作为一种实现方法,在上述步骤302a之前,RAN还可以与AMF之间相互交互能力信息。比如RAN向AMF发送第一能力信息,第一能力信息用于指示RAN支持基于PLMN粒度或终端设备粒度上报统计信息;RAN从AMF接收第二能力信息,第二能力信息用于指示AMF支持向SMF或CHF上报统计信息。从而,当RAN获知AMF支持向SMF或CHF上报统计信息,才执行上述步骤302a。
当上述步骤301a中生成的是PLMN粒度的统计信息,也即RAN上报的统计信息用于指示RAN下的归属于第一PLMN的多个终端设备对RAN上的第二PLMN的资源的使用情况,则该统计信息包括但不限于以下信息中的一项或多项:
1)、第一PLMN的频谱占用信息
作为一种实现方法,第一PLMN的频谱占用信息包括归属于第一PLMN的多个终端设备占用的频谱带宽和占用频谱带宽的持续时长。其中,占用的频谱带宽包括第一PLMN的频谱带宽和第二PLMN的频谱带宽,占用频谱带宽的时长包括占用第一PLMN的频谱带宽的时长和占用第二PLMN的频谱带宽的时长。作为一个示例,RAN下的第一PLMN提供100M带宽,第二PLMN也提供100M带宽,这200M带宽作为第一PLMN与第二PLMN的共享带宽。比如,在设定的30分钟时长内,归属于第一PLMN的多个终端设备在第1个10分钟占用了80M,在第2个10分钟占用了120M,在第3个10分钟占用了150M,则第一PLMN的频谱占用信息可以是以下信息中的任一种:
a、(270M,20分钟/起止时刻值);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的带宽均超过了100M,因此均占用了第二PLMN的带宽,因此可以上报这两个10分钟的占用带宽和持续时长,也即120M+150M=270M,且占用时长为20分钟。其中,这里的20分钟也可以用占用的起止时刻值来替代,比如起止时刻值为(12:10,12:30),或者为((12:10,12:20),(12:30,12:40))等。
b、((120M,10分钟/起止时刻值),(150M,10分钟/起止时刻值));
由于在第2个10分钟和第3个10分钟,第一PLMN占用的带宽均超过了100M,因此均占用了第二PLMN的带宽,因此可以分别上报这两个10分钟的占用带宽和持续时长。其中,这里的10分钟可以用占用的起止时刻值来替代。比如,占用的120M带宽的起止时刻值为(12:10,12:20),占用的150M带宽的起止时刻值为(12:30,12:40))。
c、(2700M*分钟);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的带宽均超过了100M,因 此均占用了第二PLMN的带宽,因此可以上报这两个10分钟的占用带宽。比如可以上报占用的带宽总量,即120M*10分钟+150M*10分钟=2700M*分钟。
当然,针对上述方式a至c,还可以上报没有占用第二PLMN带宽时的带宽使用信息。
比如,结合上述方式a,则可以上报(350M,30分钟/起止时刻值)。
再比如,结合上述方式b,则可以上报((80M,10分钟/起止时刻值),(120M,10分钟/起止时刻值),(150M,10分钟/起止时刻值))。
再比如,结合上述方式c,则可以上报(3500M*分钟)。
作为另一种实现方法,第一PLMN的频谱占用信息包括归属于第一PLMN的多个终端设备占用的第二PLMN的频谱带宽和占用第二PLMN的频谱带宽的持续时长。作为一个示例,RAN下的第一PLMN提供100M带宽,第二PLMN也提供100M带宽,这200M带宽作为第一PLMN与第二PLMN的共享带宽。比如,在设定的30分钟时长内,归属于第一PLMN的多个终端设备在第1个10分钟占用了80M,在第2个10分钟占用了120M,在第3个10分钟占用了150M,则第一PLMN的频谱占用信息可以是以下信息中的任一种:
a、(70M,20分钟/起止时刻值);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的带宽均超过了100M,因此均占用了第二PLMN的带宽,因此可以上报这两个10分钟超出占用带宽和持续时长,也即(120M-100M)+(150M-100M)=70M,且占用时长为20分钟。其中,这里的20分钟也可以用占用的起止时刻值来替代,比如起止时刻值为(12:10,12:30),或者为((12:10,12:20),(12:30,12:40))等。
b、((20M,10分钟/起止时刻值),(50M,10分钟/起止时刻值));
由于在第2个10分钟和第3个10分钟,第一PLMN占用的带宽均超过了100M,因此均占用了第二PLMN的带宽,因此可以分别上报这两个10分钟分别超出占用带宽和持续时长。其中,这里的10分钟可以用占用的起止时刻值来替代。比如,超出占用的20M带宽的起止时刻值为(12:10,12:20),超出占用的150M带宽的起止时刻值为(12:30,12:40))。
c、(700M*分钟);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的带宽均超过了100M,因此均占用了第二PLMN的带宽,因此可以上报这两个10分钟超出占用的占用带宽。比如可以上报超出占用的带宽总量,即20M*10分钟+50M*10分钟=700M*分钟。
当然,针对上述方式a至c,还可以上报没有占用第二PLMN带宽时的带宽使用信息。
比如,结合上述方式a,则可以上报(50M,30分钟/起止时刻值)。也即(80M+120M+150M)-100M*3=50M。
再比如,结合上述方式c,则可以上报(500M*分钟)。
作为又一个示例,RAN下的第一PLMN提供频段A,第二PLMN提供频段B,频段A和频段B作为第一PLMN与第二PLMN的共享频段。比如,在设定的30分钟时长内,归属于第一PLMN的多个终端设备在第1个10分钟占用了频段A的30M带宽,在第2个10分钟占用了频段B的50M带宽,在第3个10分钟占用了频段A的20M带宽和频段B的40M带宽,则第一PLMN的频谱占用信息可以是以下任一种:
a、(90M,20分钟/起止时刻值);
由于在第2个10分钟和第3个10分钟,第一PLMN占用了第二PLMN的频段B,因此可以上报这两个10分钟占用频段B的总带宽和持续时长。也即,占用第二PLMN的频段B的带宽为50M+40M=90M,且持续时长为20分钟。其中,这里的20分钟可以用占用的起止时刻值来替代。比如,占用第二PLMN的频段B的起止时刻值为(12:10,12:30),或者为((12:10,12:20),(12:30,12:40))等。
b、((50M,10分钟/起止时刻值),(40M,10分钟/起止时刻值));
由于在第2个10分钟和第3个10分钟,第一PLMN占用了第二PLMN的频段B,因此可以分别上报这两个10分钟占用频段B的带宽和持续时长。其中,这里的10分钟可以用占用的起止时刻值来替代。比如,第2个10分钟的起止时刻值为(12:10,12:20),第3个10分钟的起止时刻值为(12:30,12:40))。
c、(900M*分钟);
由于在第2个10分钟和第3个10分钟,第一PLMN占用了第二PLMN的频段B,因此可以上报这两个10分钟占用频段B的带宽。比如可以上报占用频段B的带宽总量,即50M*10分钟+40M*10分钟=900M*分钟。
当然,针对上述方式a至c,还可以上报没有占用第二PLMN的频段时的带宽使用信息。
比如,结合上述方式a,则可以上报(140M,30分钟/起止时刻值)。也即(30M+50M+20M+40M)=140M。
再比如,结合上述方式b,则可以上报(1400M*分钟)。
可选的,上述实现方法中,RAN可以通过以下方法统计第一PLMN下的多个终端设备的带宽占用情况:
方法1,先基于终端设备粒度统计第一PLMN下的每个终端设备分别对于第一PLMN的带宽占用情况和持续时长,和/或对于第二PLMN的占用情况和持续时长,然后对这些终端设备的带宽占用情况进行累计汇总,得到第一PLMN下的多个终端设备的带宽占用情况。
方法2,绘制出第一PLMN下的每个终端设备对于第一PLMN的带宽和第二PLMN的带宽的占用情况的变化曲线,该变化曲线的横轴为时间,纵轴为第一PLMN的带宽或第二PLMN的带宽,然后对该变化曲线进行积分求面积,得到终端设备对于第一PLMN的带宽占用量、或终端设备对于第二PLMN的带宽占用量。其中,带宽占用情况的最小变化单位可以是RAN调度终端设备的单位调度周期,即资源调度的最小时间单位,例如1ms,0.5ms等。其中,得到的带宽占用量的单位可以是兆*时间单位,这里的时间单位可以是毫秒、秒或分钟等。然后对这些终端设备的带宽占用情况进行叠加汇总,得到第一PLMN下的多个终端设备的带宽占用情况。
或者,可选的,上述实现方法中,RAN还可以在设定时长内给第一PLMN下的多个终端设备分配相应的带宽资源,即固定的带宽占用情况。例如,RAN在10点至10点5分将3.48G至3.60G这120M分配给第一PLMN下的多个终端设备使用;RAN在10点6分至10点10分将3.49G至3.60G这110M分配给第一PLMN下的多个终端设备使用。
2)、数据无线承载(Data Radio Bearer,DRB)信息
DRB占用信息包括归属于第一PLMN的多个终端设备占用的DRB数量和DRB数量的持续时长。

a、(140个,20分钟/起止时刻值);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的DRB数量均超过了50个,因此均占用了第二PLMN的DRB,因此可以上报这两个10分钟的占用的DRB数量和DRB数量的持续时长,也即60+80=140个,且DRB数量的持续时长为20分钟。其中,这里的20分钟也可以用占用的起止时刻值来替代,比如起止时刻值为(12:10,12:30),或者为((12:10,12:20),(12:30,12:40))等。
b、((60个,10分钟/起止时刻值),(80个,10分钟/起止时刻值));
由于在第2个10分钟和第3个10分钟,第一PLMN占用的DRB数量均超过了50个,因此均占用了第二PLMN的DRB,因此可以分别上报这两个10分钟的占用的DRB数量和DRB数量的持续时长。其中,这里的10分钟可以用占用的起止时刻值来替代。比如,占用的120M带宽的起止时刻值为(12:10,12:20),占用的150M带宽的起止时刻值为(12:30,12:40))。
c、(1400个*分钟);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的DRB数量均超过了50个,因此均占用了第二PLMN的DRB,因此可以上报这两个10分钟的占用的DRB数量。比如可以上报占用的DRB总数量,即60个*10分钟+80个*10分钟=1400个*分钟。
当然,针对上述方式a至c,还可以上报没有占用第二PLMN的DRB数量时的DRB占用信息。
比如,结合上述方式a,则可以上报(180个,30分钟/起止时刻值)。
再比如,结合上述方式b,则可以上报((40个,10分钟/起止时刻值),(60个,10分钟/起止时刻值),(80个,10分钟/起止时刻值))。
再比如,结合上述方式c,则可以上报(1800个*分钟)。
或者,可选的,第一PLMN的DRB占用信息包括归属于第一PLMN的多个终端设备占用的第二PLMN的DRB数量和第二PLMN的DRB数量的占用时长。作为一个示例,RAN下的第一PLMN和第二PLMN各自可以分配50个DRB,这100个DRB可以由第一PLMN与第二PLMN共享使用。比如,在设定的30分钟时长内,归属于第一PLMN的多个终端设备在第1个10分钟占用了40个DRB,在第2个10分钟占用了60个DRB,在第3个10分钟占用了80个DRB,则第一PLMN的DRB占用信息可以是以下信息中的任一种:
a、(40个,20分钟/起止时刻值);
由于在第2个10分钟和第3个10分钟,第一PLMN占用的DRB数量均超过了50个,因此均占用了第二PLMN的DRB,因此可以上报这两个10分钟的占用的第二PLMN的DRB数量和第二PLMN的DRB数量的持续时长,也即(60-50)+(80-50)=40个,且第二PLMN的DRB数量的持续时长为20分钟。其中,这里的20分钟也可以用占用的起止时刻值来替代,比如起止时刻值为(12:10,12:30),或者为((12:10,12:20),(12:30,12:40))等。

6)、归属于第一PLMN的多个终端设备使用的无线接入技术(Radio Access Technology,RAT)和使用RAT的持续时长
归属于第一PLMN的多个终端设备使用的RAT,指的是终端设备接入到第一PLMN所使用的通信技术,如4G或5G等。
基于RAN上报的上述1)至6)中的一项或多项不同维度的PLMN粒度的统计信息,CHF可以进行运营商之间的精细化的合理计费,可以更好地实现和监督频谱的合理高效使用。

可选的,占用的频谱带宽包括第一PLMN的频谱带宽和第二PLMN的频谱带宽,占用频谱带宽的时长包括占用第一PLMN的频谱带宽的时长和占用第二PLMN的频谱带宽的时长。作为一个示例,RAN下的第一PLMN提供频段A,第二PLMN提供频段B,频段A和频段B作为第一PLMN与第二PLMN的共享频段。比如,在设定的30分钟时长内,归属于第一PLMN的终端设备1在第1个10分钟占用了频段A的30M带宽,在第2个10分钟占用了频段B的50M带宽,在第3个10分钟占用了频段A的20M带宽和频段B的40M带宽,则终端设备1的频谱占用信息可以是以下任一种:
a、(140M,30分钟/起止时刻值);
也即,占用的频谱带宽为30M+50M+20M+40M=140M,且持续时长为30分钟。其中,这里的30分钟可以用占用的起止时刻值来替代。比如,起止时刻值为(12:10,12:40),或者为((12:10,12:20),(12:30,12:40),(12:45,12:55))等。
b、((频段A,30M,10分钟/起止时刻值),(频段B,50M,10分钟/起止时刻值),(频段A,20M,频段B,40M,10分钟/起止时刻值));

或者,第一终端设备的频谱占用信息包括占用的第二PLMN的频谱带宽和占用第二PLMN的频谱带宽的时长。作为又一个示例,RAN下的第一PLMN提供频段A,第二PLMN提供频段B,频段A和频段B作为第一PLMN与第二PLMN的共享频段。比如,在设定的30分钟时长内,归属于第一PLMN的终端设备1在第1个10分钟占用了频段A的30M带宽,在第2个10分钟占用了频段B的50M带宽,在第3个10分钟占用了频段A的20M带宽和频段B的40M带宽,则终端设备1的频谱占用信息可以是以下任一种:
a、(90M,20分钟/起止时刻值);
由于在第2个10分钟和第3个10分钟,终端设备1占用了第二PLMN的频段B,因此可以上报这两个10分钟占用频段B的总带宽和持续时长。也即,占用第二PLMN的频段B的带宽为50M+40M=90M,且持续时长为20分钟。其中,这里的20分钟可以用占用的起止时刻值来替代。比如,占用第二PLMN的频段B的起止时刻值为(12:10,12:30),或者为((12:10,12:20),(12:30,12:40))等。
b、((50M,10分钟/起止时刻值),(40M,10分钟/起止时刻值));

或者,可选的,上述实现方法中,RAN还可以在设定时长内给第一PLMN下的第一终端设备分配相应的带宽资源,即固定的带宽占用情况。例如,RAN在10点至10点5分将3.48G至3.60G这120M分配给第一PLMN下的第一终端设备使用;RAN在10点6分至10点10分将3.49G至3.60G这110M分配给第一PLMN下的第一终端设备使用。

具体的,第一终端设备成功接入第一PLMN并建立或激活PDU会话后,RAN上会为该PDU会话建立与第一终端设备之间的DRB,将PDU会话的不同QoS Flow映射到相应的DRB中。因此,RAN可以知道QoS flow的上下文信息的,包括该QoS flow的切片/DN。

5)、第一终端设备使用的RAT和使用RAT的持续时长
第一终端设备使用的RAT,指的是第一终端设备接入到第一PLMN所使用的通信技术,如4G或5G等。
基于RAN上报的上述1)至5)中的一项或多项不同维度的终端设备粒度的统计信息,CHF可以根据多个终端设备的统计信息,汇聚成PLMN粒度的统计信息,并基于PLMN粒度的统计信息进行运营商之间的精细化的合理计费,可以更好地实现和监督频谱的合理高效使用。
如图3(b)所示,为本申请实施例提供的另一种通信方法,该方法可以与上述图3(a)所示的通信方法相结合实施例。该方法包括以下步骤:
步骤301b,第一网元确定终端设备处于连接态,其中,终端设备接入的RAN为第一PLMN与第二PLMN共享使用RAN。
这里的第一网元可以是归属于第二PLMN的CHF、或者是SMF。
当第一网元确定终端设备处于连接态,则确定可以使用该终端设备的信令来上报统计信息,这里的统计信息用于指示RAN下的归属于第一PLMN的至少一个终端设备对RAN上的第二PLMN的资源的使用情况。
其中,第一网元可以根据以下方法确定终端设备处于连接态:
方法一,第一网元确定终端设备的至少一个PDU会话处于激活态,则确定终端设备处于连接态。
也即,当终端设备上存在至少一个处于激活态的PDU会话,则该终端设备处于连接态。
方法二,第一网元获取终端设备的状态信息;根据状态信息确定终端设备处于连接态。
这里的状态信息用于记录终端设备当前所处的状态,如连接态、空闲态、RRC非激活态,不活跃态等。当第一网元获取到终端设备的状态信息所指示的终端设备的状态为连接态,则确定终端设备处于连接态。
步骤302b,第一网元发送第一指示信息,第一指示信息用于指示接入网设备通过终端设备的信令上报统计信息。
比如,当第一网元是CHF,则该步骤302b中,CHF可以向SMF发送第一指示信息、或者向AMF发送第一指示信息。可选的,SMF或AMF向RAN发送第一指示信息,RAN根据第一指示信息,将统计信息携带在终端设备的信令中发送至SMF或AMF,然后SMF 或AMF向CHF发送统计信息。进而CHF可以根据统计信息进行计费。
再比如,当第一网元是SMF,则该步骤302b中,SMF可以向AMF发送第一指示信息。例如,SMF向AMF发送携带第一指示信息的N2会话管理信息,则AMF无法解析N2会话管理信息以获得第一指示信息,而是将携带第一指示信息的N2会话管理信息透传至RAN。可选的,RAN可以基于第一指示信息向AMF上报统计信息(比如将统计信息携带于N2会话管理信息中发送至AMF,该N2会话管理信息是终端设备的信令),AMF将统计信息上报至SMF,该情形下AMF是将来自RAN的统计信息透传至SMF。再例如,SMF向AMF发送携带第一指示信息的第一信息,其中,AMF可以解析该第一信息以获得第一指示信息,然后AMF向RAN发送第一指示信息,可选的,RAN可以基于第一指示信息向AMF上报统计信息(具体是通过终端设备的信令携带统计信息),AMF将统计信息上报至SMF,该情形下AMF是可以获得来自RAN的统计信息,然后将统计信息发送至SMF。
作为一种实现方法,在上述步骤301b之前,或者是在步骤301b之后、在步骤302b之前,第一网元还确定RAN是共享RAN。比如,第一网元可以从AMF接收第二指示信息,第二指示信息用于指示上述RAN是共享RAN,则第一网元可以根据该第二指示信息确定上述RAN是共享RAN。进一步的,第一网元还可以获知上述终端设备的位置信息(如RAN的标识、小区的标识、或跟踪区标识(Tracking Area Identity,TAI)),并根据终端设备的位置信息确定终端设备处于上述RAN的覆盖范围。或者理解为,第一网元确定上述终端设备接入的RAN是共享RAN。
当然,如果协议规定或者是网络预先约定,上述RAN默认支持共享,则第一网元无需判断上述RAN是否为共享RAN。
基于上述方案,可以由第一网元确定某个终端处于连接态时,指示通过该终端设备的信令来上报统计信息,可以实现共享同一接入网设备的不同PLMN之间的相互计费,有助于实现费用的精确计算。
下面结合附图4至附图7,介绍上报上述统计信息的不同实现方法。其中,图4至图6对应的实施例中,RAN上报的是PLMN粒度的统计信息。图7至图8对应的实施例中,RAN上报的是终端设备粒度的统计信息。

该第一能力信息用于指示RAN支持基于PLMN粒度上报统计信息。
作为一种实现方法,RAN可以将上述第一能力信息携带于NG建立请求(NG setup request)中发送至AMF。
其中,RAN向AMF发送的第一能力信息是可选操作。也即可以向AMF上报第一能力信息,也可以不上报第一能力信息。
步骤401b,AMF向RAN发送第二能力信息。相应地,RAN可以接收到第二能力信 息。
该第二能力信息用于指示AMF支持向SMF上报统计信息。

通过上述步骤401a至步骤401b,在RAN和AMF上电启动之后,RAN和AMF可以建立节点级信令连接。
步骤402a,SMF向AMF发送统计信息订阅请求。相应地,AMF可以接收到统计信息订阅请求。
该统计信息订阅请求用于请求订阅AMF获取到的统计信息。该统计信息订阅请求比如可以是订阅统计信息通知事件,比如具体可以是Namf_Commnication_Charginginfo notify subscribe request。
步骤402b,AMF向SMF发送统计信息订阅响应。相应地,AMF可以接收到统计信息订阅响应。
该统计信息订阅请响应用于指示订阅成功。该统计信息订阅响应比如可以是Namf_Commnication_Charginginfo notify subscribe response。
步骤403,RAN生成统计信息,并确定触发上报统计信息。
比如,可以在RAN上设置定时器,在定时器到期后,触发RAN上报统计信息。
步骤404a,RAN向AMF发送统计信息上报请求(charging info transfer request),其中携带统计信息。相应地,AMF可以接收到统计信息上报请求。
上述统计信息上报请求为RAN和AMF之间的节点级信令,而不是终端设备粒度的信令。
步骤404b,AMF向RAN发送统计信息上报响应(charging info transfer response)。相应地,AMF可以接收到统计信息上报响应。
步骤405,AMF向SMF发送统计信息。相应地,SMF可以接收到统计信息。
也即,AMF基于SMF的订阅,在从RAN接收到统计信息后,向SMF上报统计信息。比如将统计信息携带于Namf_Communication_Charginginfo notify中发送至SMF。
步骤406,SMF向CHF发送统计信息。相应地,CHF可以接收到统计信息。
基于上述方案,RAN通过节点级信令将PLMN粒度的统计信息上报给CHF,以使得CHF可以根据该统计信息进行运营商之间的计费操作。
如图5所示,为本申请实施例提供的又一种通信方法,该方法由RAN通过节点级信令上报PLMN粒度的统计信息给AMF,然后由AMF将统计信息上报给CHF。
该方法包括以下步骤:
步骤501a,RAN和AMF建立下一代接入点(Next Generation Access Point,NG-AP)连接时,RAN向AMF发送第一能力信息。相应地,AMF可以接收到第一能力信息。

步骤505,AMF向CHF发送统计信息。相应地,CHF可以接收到统计信息。
也即,AMF基于CHF的订阅,在从RAN接收到统计信息后,向CHF上报统计信息。比如将统计信息携带于Namf_Communication_Charginginfo notify中发送至CHF。
基于上述方案,RAN通过节点级信令将PLMN粒度的统计信息上报给CHF,以使得CHF可以根据该统计信息进行运营商之间的计费操作。
如图6所示,为本申请实施例提供的又一种通信方法,该方法由RAN通过终端信令上报PLMN粒度的统计信息给SMF,然后由SMF将统计信息上报给CHF。

步骤606,RAN向AMF发送统计信息。相应地,AMF可以接收到统计信息。
可选的,统计信息携带于N2会话管理信息中发送至AMF,从而AMF只需要将N2会话管理信息透传至SMF。
步骤607,AMF向SMF发送统计信息。相应地,SMF可以接收到统计信息。
比如,AMF可以将统计信息携带于Nsmf_PDU Session_UpdateSMContext request中发送至SMF。可选的,将N2会话管理信息携带于Nsmf_PDU Session_UpdateSMContext request,该N2会话管理信息携带统计信息。

下面给出另一种统计信息的上报方式,该方法中不是以PLMN粒度进行统计信息的上报,而是以终端设备粒度进行统计信息的上报,并由SMF或CHF对接收到的终端设备粒度的统计信息进行汇聚,从而得到PLMN粒度的统计信息。
如图7所示,为本申请实施例提供的又一种通信方法,该方法是由RAN通过终端设备级信令上报终端粒度的统计信息给SMF,然后由SMF或CHF对接收到的不同终端设备的统计信息进行汇聚。

这里的统计信息是终端设备粒度的统计信息,该统计信息用于指示RAN下的归属于第一PLMN的一个终端设备对RAN上的第二PLMN的资源的使用情况。

步骤706,SMF向CHF发送汇聚的统计信息。相应地,CHF可以接收到该汇聚的统计信息。

步骤705’,SMF向CHF发送终端设备的统计信息。相应地,CHF可以接收到终端设备的统计信息。
步骤706’,CHF根据多个终端设备的统计信息,得到汇聚的统计信息。
比如,CHF根据在某个时刻或某个时间段内接收到的多个终端设备的统计信息,进行PLMN粒度的统计信息的汇聚,得到汇聚的统计信息。
基于上述方案,RAN以终端设备级信令将终端设备粒度的统计信息上报给SMF/CHF,由SMF/CHF根据终端设备的统计信息得到PLMN粒度的汇聚的统计信息,使得CHF可以根据该汇聚的统计信息进行运营商之间的计费操作。
