背景技术
目前,双卡双待的终端设备越来越多。但是,目前的终端设备都不支持纯粹的双通,即终端设备不能通过两个全球用户识别模块(universal subscriber identity module,USIM)卡在两个网络上进行上行和下行的数据业务,也就意味着终端设备在某一时刻只能执行一张USIM卡上的业务。
对于同时安装了USIM-1卡和USIM-2卡的终端设备,则会存在如下问题:如果终端设备正在USIM-1卡上进行数据业务,收到USIM-2卡对应的网络发送的寻呼请求,是否需要切换到USIM-2卡上。因此,终端设备是切换到USIM-2卡上进行业务,还是停留在USIM-1卡上继续进行当前的业务,这是个亟需解决的问题。

作为又一示例,本申请实施例中的第一通信系统和第二通信系统不同,但对第一通信系统和该第二通信系统的具体类别不作限定。

该第一网络设备130可以为LTE网络设备,该第二网络设备120可以为NR网络设备。或者该第一网络设备130可以为NR网络设备,第二网络设备120可以为LTE网络设备。或者该第一网络设备 130和该第二网络设备120都可以为NR网络设备。或者该第一网络设备130可以为GSM网络设备,CDMA网络设备等,该第二网络设备120也可以为GSM网络设备,CDMA网络设备等。或者第一网络设备130可以是宏基站(Macrocell),第二网络设备120可以为微蜂窝基站(Microcell)、微微蜂窝基站(Picocell)或者毫微微蜂窝基站(Femtocell)等。

应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。
双SIM卡终端是未来的发展趋势,然而,当前的终端一般不支持纯粹的双通的能力,双通可以理解为双发双收,即在两个网络上同时发送和接收数据。因此,终端设备不能通过两个SIM卡在两个网络上同时进行上行(uplink,UL)和下行(downlink,UL)的数据业务。
一般来说,目前的终端设备大多数都只支持单上行/下行(Single UL/DL),或单上行/双下行(Single UL/Dual DL),这也就意味着终端设备在某一时刻只能执行一张SIM卡上的业务。其中,Single UL/DL表示终端设备在某一时刻只能执行一张SIM卡上的上行和下行业务;Single UL/Dual DL表示终端设备在某一时刻可以同时执行两张SIM卡上的业务,但只能执行一张SIM卡上的上行业务。
如果终端设备同时安装了SIM-1卡和SIM-2卡,当终端设备只支持Single UL/DL或Single UL/Dual DL时,会存在如下问题:
情况1,如果终端设备只支持Single UL/DL,且终端设备在SIM-1和SIM-2上均处于无线资源控制(radio resource control,RRC)空闲态或RRC非连接态,则会存在寻呼冲突的情况。
情况2,如果终端设备只支持Single UL/DL,且终端设备在SIM-1上处于RRC空闲态或非连接态,在SIM-2上处于RRC连接态,则会存在SIM-1上的低优先级的业务中断了SIM-2上的高优先级的业务的现象,或者终端设备在某些事件内不能接收到SIM-1上的业务的寻呼。
情况3,如果终端设备只支持Single UL/Dual DL,且终端设备在SIM-1上处于RRC空闲态或非连接态,在SIM-2上处于RRC连接态,则终端设备会由于回复SIM-1卡上的寻呼(如RRC连接建立)而中断SIM-2上的业务。
针对上述情况,如图2所示,终端设备安装有两张SIM卡,即USIM-1和USIM-2,终端设备的USIM-1卡对应的网络为网络1,终端设备的USIM-2卡对应的网络为网络2。网络1包括接入网1(radio access network 1,RAN-1)和核心网1(core network 1,CN-1),网络2包括RAN-2和CN-2。
S210、终端设备与网络2处于连接状态,与网络1处于非连接状态。终端设备在网络2(RAN-2+CN-2)上执行USIM-2上的数据业务。
S220、由于第一网络上的业务的触发,CN-1向RAN-1发送寻呼请求,以请求终端设备建立与第一网络的连接。
S230、RAN-1接收到CN-1发的寻呼请求后,向终端设备发送寻呼请求。
终端设备接收到RAN-1发送的寻呼请求后,是否切换到USIM-2上?例如,如果终端设备接收到寻呼请求时,正在第二网络上执行业务,如语音业务,则终端设备是否需要切换到USIM-1上。因此,终端设备应该停止在网络1上的业务而切换到SIM-2上,还是忽略网络1的寻呼而维持与网络1的连接,继续进行当前的业务,这是亟需解决的问题。
本申请实施例提供了一种通信方法,为支持多SIM卡的终端设备提供了一种确定是否进行SIM卡 切换的方式。如图3所示,该方法包括步骤S310~S320。
S310、第一网络向终端设备发送第一消息,该第一消息中包括第一信息,且第一消息用于请求终端设备建立与第一网络的连接。
S320、终端设备根据第一信息,确定是否建立与第一网络的连接。
该第一网络可以指第一网络设备,该第一网络设备可以指核心网设备,该核心网设备可以指上文描述的CN-1;或者改第一网络设备可以指接入网设备,该接入网设备可以指上文描述的RAN-1。
该终端设备与第一网络处于非连接状态,如终端设备与第一网络处于RRC空闲(idle)态,或终端设备与第一网络处于RRC非激活(inactive)态。
该终端设备可以为支持多SIM卡的终端设备,假设终端设备中安装的SIM卡包括USIM-1和USIM-2,USIM-1对应于第一网络,USIM-2对应于第二网络,终端设备当前处于与第二网络的连接态,而与第二网络处于非连接态。
当终端设备处于与第二网络的连接态时,终端设备可以进行USIM-2上的业务。终端设备处于与第二网络的连接态可以包括终端设备处于与第二网络的RRC连接态和/或连接管理(connection management,CM)连接态。
第一消息可以为寻呼消息,当第一网络检测到有业务需要触发寻呼时,可以向终端设备发送寻呼消息,以使终端设备处理该业务。例如,当第一网络检测到有应用数据包或第三方触发的请求消息时,可以向终端设备发送寻呼消息。
第一信息中可以包括业务信息,以便于终端设备根据该业务信息确定是否切换到第一网络。如果终端设备判断该业务比较重要或比较紧急,如第一信息中包括地震海啸预警等信息,则终端设备可以切换到第一网络处理该业务;如果终端设备判断该业务不重要或不紧急,如为垃圾短信或广告等,则终端设备可以忽略该消息,而继续停留在当前的网络。
该业务信息可以包括业务标识,该业务标识可以表示触发第一网络发送第一消息的业务。
业务标识可以通过以下信息中的至少一种来体现:应用(Application)标识(identity,ID),服务(Service)ID,互联网协议(Internet Protocol,IP)地址,媒体接入控制(Media Access Control,MAC)地址,虚拟局域网(Virtual Local Area Network,VLAN)ID,数据网络名称(date network name,DNN)和接入点名称(Access Point Name,APN)。
业务标识也可以表征不同的业务类型,如紧急呼叫、语音业务、短信业务、IP多媒体子系统(IP Multimedia Subsystem,IMS)业务等。
此外,该第一信息还可以包括业务标识及业务标识对应的优先级。第一信息中触发第一消息的业务及其对应的优先级,终端设备可以根据触发第一消息的业务的优先级,确定是否需要建立与第一网络的连接。
当然,第一消息中还可以包括多个业务标识及其对应的优先级,每个业务标识都有其对应的优先级,不同的业务的优先级可以相同,也可以不同。
可以理解的是,第一信息并不局限于包括业务信息,第一信息也可以包括其他的信息,例如触发事件等。终端设备可以根据触发事件确定是否需要建立与第一网络的连接。
本申请实施例中,终端设备可以根据第一信息中的内容,如业务信息,自主确定是否需要切换到第一网络,这为支持多SIM卡的终端设备提供了一种网络切换策略,能够降低终端设备的复杂度。
终端设备可以根据第一信息,以及以下信息中的至少一种:第二信息,终端设备在第二网络中正在进行的业务,确定是否建立与第一网络的连接。
该第二信息可以理解为一种策略,该第二信息可以包括以下信息中的至少一种:业务优先级,需要终端设备建立与第一网络的连接的业务,和不需要终端设备建立与第一网络的连接的业务。
第二信息在不同的时间和/不同的地点下对应不同的信息。例如,第二信息包含不同时间和/或不同地点下的业务优先级,在不同时间和/或不同地点下,相同业务的优先级可以不同。又例如,在不同的时间和/或不同地点下,第二信息中包括的需要终端设备建立与第一网络的连接的业务不同。
业务优先级可以包括不同的业务及其对应的业务优先级。如表1所示,表1示出了一种表示业务优先级的方式。
表1
业务 优先级(1-9)
业务-1 1
业务-2 3
业务-3 6
业务-4 4
表1共示出了4种业务及其对应的优先级,业务-1的优先级为1,业务-2的优先级为3,业务-3的优先级为6,业务-4的优先级为4。在表1中,优先级的数字越小,表示有限程度越高,即业务-1的优先级最高,业务3的优先级最低,业务-2的优先级高于业务-4的优先级。
本申请实施例中的业务优先级可以包括特定时间下的业务优先级和/或特定地点下的业务优先级,也就是说,对于同一个业务,在不同的时间和/或地点,其优先级不同,如表2和表3所示。
表2
Figure PCTCN2019115428-appb-000001
表2示出了对于相同的业务在两个不同的时间下的业务优先级的情况。对于业务1,在时间1下的优先级1为1,但是在时间2下的优先级为3;对于业务2,在时间1下的优先级为4,但是在时间2下的优先级为2;对于业务3,在时间1下的优先级为6,但是在时间2下的优先级为7;对于业务4,在时间1下的优先级为8,在时间2下的优先级为5。
参见表2,在时间1下,业务1的优先级高于业务2的优先级,但是在时间2下,业务2的优先级高于业务1的优先级。因此,终端设备在确定第一信息中包括的业务的优先级时,可以先判断当前处于哪个时间,然后将该时间对应的优先级作为业务的优先级。
时间1和时间2可以分别表示白天和晚上,或者时间1和时间2分别表示周内和周末等。当然,本申请实施例还可以划分更多的时间点,例如,上班时间,下班时间,吃饭时间,睡觉时间等。
表3
Figure PCTCN2019115428-appb-000002
表3示出了对于相同的业务在两个不同的地点下的优先级的情况。对于业务1,在地点1下的优先级为4,但是在地点2下的优先级为2;对于业务2,在地点1下的优先级为1,但是在地点2下的优先级为6;对于业务3,在地点1下的优先级为3,但是在地点2下的优先级为5;对于业务4,在地点1下的优先级为7,但是在地点2下的优先级为8。
参见表3,在地点1下,业务1的优先级高于业务2的优先级,但是在地点2下,业务2的优先级高于业务1的优先级。因此,终端设备在确定第一信息中包括的业务的优先级时,可以先判断终端设备处于哪个地点,然后将该地点对应的优先级确定为业务的优先级。
地点1和地点2可以分别表示家里和单位。当然,本申请实施例还可以划分更多的地点,例如,该高铁上,飞机上等。
表1、表2和表3仅是一种示例,以优先级在1-9的范围内进行举例,但本申请实施例并不限于此,可以将业务的优先级划分得更细一些,如将业务的优先级划分为1-20共20个等级。
可以理解的是,业务优先级也可以包括特定时间和特定地点下的优先级,也就是说,业务的优先级与时间和地点均相关,业务优先级是两个维度下的优先级。在该情况下,业务优先级是表2和表3共同的结果,表2可以表示某个地点下的业务优先级,表3可以表示某个时间下的业务优先级。
对于同一个业务,即使时间相同,但是地点不同,优先级可能也不同。终端设备在确定第一信息中包括的业务的优先级时,不仅要判断终端设备所处的时间,还要判断终端设备所处的地点,根据终端设 备的时间和地点信息确定业务的优先级。
本申请实施例对业务的区分粒度不做具体限定。例如,业务可以划分为以下中的至少一种:
基于IP多媒体子系统(IP Multimedia Subsystem,IMS)和non-IMS的语音服务;
基于IMS和non-IMS的短信服务(Short Message Service,SMS)和非结构化补充数据(unstructured supplementary services date,USSD);
除了语音和SMS之外的IMS服务;
以上位列出的其他数据服务,例如视频。
为方便描述,下文将需要终端设备建立与第一网络的连接的业务称为第一业务组,将不需要终端设备建立与第一网络的连接的业务称为第二业务组。第二信息可以仅包括第一业务组,也可以仅包括第二业务组,第二信息也可以同时包括第一业务组和第二业务组。
作为一个示例,终端设备可以根据第一信息以及第二信息,确定是否建立与第一网络的连接。如果第二信息包括业务优先级,第一信息包括业务信息,则终端设备可以根据第一信息中包括的业务的优先级,以及业务优先级,确定是否建立与第一网络的连接。如果第二信息包括第一业务组,且第一信息包括的业务属于第一业务组,则终端设备可以建立与第一网络的连接。如果第二信息包括第一业务组,且第一信息包括的业务不属于第一业务组,则终端设备可以不建立与第一网络的连接。如果第二信息包括第二业务组,且第一信息包括的业务属于第二业务组,则终端设备可以不建立与第一网络的连接。如果第二信息包括第二业务组,则终端设备可以建立与第一网络的连接。
终端设备根据第一信息中包括的业务所属的业务组,确定是否建立与第一网络的连接的方式比较简单,当终端设备接收到第一网络发送的第一消息时,仅需判断第一信息中包括的业务属于哪个业务组,就可直接确定是会否需要建立与第一网络的连接。
终端设备根据第一信息中包括的业务的优先级,以及业务优先级,确定是否建立与第一网络的连接的方式有很多。
例如,终端设备可以根据第一信息中包括的业务在业务优先级中的排序或级别,确定是否建立与第一网络的连接。如果第一信息中包括的业务在业务优先级中的排序比较靠前,如中等偏上,则终端设备可以建立与第一网络的连接;如果第一信息中包括的业务在业务优先级中的排序比较靠后,如中等偏下,则终端设备可以不建立与第一网络的连接。
有例如,终端设备可以根据第一信息中包括的业务,以及终端设备在第二网络中正在进行的业务,确定是否建立与第一网络的连接。终端设备接收到第一消息后,可以判断第一信息中的业务与第二网络中正在进行的业务哪个比较重要。如果第一信息中的业务比较重要,则终端设备可以建立与第一网络的连接;如果终端设备在第二网络中正在进行的业务比较重要,如第二网络中正在进行的是通话业务,而第一信息中的业务仅是广告短信,则终端设备可以不建立与第一网络的连接。
再例如,终端设备还可以根据第一信息中包括的业务,终端设备在第二网络中正在进行的业务,以及业务优先级,确定是否建立与第一网络的连接。具体地,终端设备可以根据第一信息中包括的业务的优先级,以及终端设备在第二网络中正在进行的业务的优先级,确定是否建立与第一网络的连接。如果第一信息中包括的业务的优先级高于第二网络中正在进行的业务的优先级,则终端设备可以建立与第一网络的连接;如果第一信息中包括的业务的优先级低于第二网络中正在进行的业务的优先级,则终端设备可以不建立与第一网络的连接;如果第一信息中包括的业务的优先级与第二网络中正在进行的业务的优先级相同,则终端设备可以建立与第一网络的连接,也可以不建立与第一网络的连接。
终端设备通过比较两个SIM卡中的业务的优先级,确定是否进行SIM卡切换的方式比较灵活,通过对USIM-2中正在进行的业务与USIM-1中请求的业务进行比较,从而选择出比较重要或比较紧急的业务进行处理,能够使得终端设备灵活调整数据处理策略。
本申请实施例中,第二信息可以是第一网络发送给终端设备的,也可以是第一网络发送给终端设备的,或者也可以是预配置在终端设备中的,如终端设备在出厂时已经预配置在终端设备中。
如果第二信息是网络设备发送给终端设备的,网络设备可以在注册流程、会话建立流程和/或UE配置更新(UE Configuration Update,UCU)流程中将第二信息发送给终端设备。例如,第二信息可以承载在以下消息中的至少一种中:注册接受(Registration Accept)消息、协议数据单元(Protocol Data Unit,PDU)会话建立接受消息、PDU会话修改接受消息和UCU流程中的消息。
该UCU流程可以是由接入及移动性管理(access and mobility management function,AMF)触发的UCU流程,也可以是由策略控制功能(policy control function,PCF)网元触发的UCU流程。
该第二信息可以是由会话管理功能(session management function,SMF)网元发送给终端设备的,也可以是由PCF网元发送给终端设备的。PCF网元将第二信息发送给终端设备,可以指PCF网元使用容器(Container)将第二信息通过AMF网元透传给终端设备。
第一网络也可以通过第一消息向终端设备发送第二信息,例如,当第一网络向终端设备发送寻呼消息时,可以将第二信息携带在该寻呼消息中发送给终端设备。
终端设备可以通过上文描述的任意一种方式确定是否需要建立与第一网络的连接。在终端设备确定需要建立与第一网络的连接的情况下,可以释放与第二网络的连接,或者称断开与第二网络的连接。如终端设备可以释放与第二网络的RRC连接和/或CM连接。
如果终端设备当前与第二网络处于RRC连接态,当终端设备确定建立与第一网络的连接时,终端设备可以释放与第二网络的RRC连接。如果终端设备当前与第二网络处于CM连接态,当终端设备确定建立与第一网络的连接时,终端设备可以释放与第二网络的CM连接。
当终端设备确定需要建立与第一网络的连接的情况下,可以向第一网络发送第一请求消息,该第一请求消息用于请求建立与第一网络的RRC连接。具体地,终端设备可以通过SIM-1向第一网络发送第一请求消息。
当然,如果终端设备支持同时在两张SIM卡上进行数据业务的能力,则终端设备可以不释放与第一网络的连接,继续保持与第一网络的连接。
终端设备建立与第一网络的连接可以包括终端设备建立与第一核心网的连接和/或终端设备建立与第一接入网的连接。
该第一请求消息可以包括RRC连接建立请求消息和/或RRC连接恢复请求消息。如果终端设备与第一网络处于RRC空闲态,则终端设备可以向第一网络发送RRC连接建立请求消息;如果终端设备与第一网络处于RRC非连接态,则终端设备可以向第一网络发送RRC连接恢复请求消息。
终端设备向第一网络发送第一请求消息时,可以在第一请求消息中携带原因值,该原因值用于指示终端设备是由于何种原因请求建立或恢复RRC连接的。
该原因值例如可以包括SIM卡切换和/或特定业务标识。SIM卡切换表示终端设备使用当前SIM卡发起RRC连接,并可能断开之前的SIM卡对应网络的连接;特定业务标识可以包括第一信息中包括的业务的标识,特定业务标识可以表示终端设备是由于特定业务的到达进行的RRC连接。
终端设备还可以向第一网络发送非接入层(non-access stratum,NAS)消息,以建立与第一网络的NAS连接,从而使终端设备进入CM连接态。
终端设备进入CM连接态后,就可以进行正常的数据的业务,即终端设备可以处理SIM-1上的数据业务。
下面结合图4,对本申请实施例提供的无线通信方法进行详细描述。如图4所示,该方法包括步骤S410~480。图4中的相应技术特征可以参见上文的描述。
S410、终端设备的SIM-1在第一网络上完成注册或附着,终端设备的SIM-2在第二网络上完成注册或附着。终端设备当前与第二网络处于CM连接态,与第一网络处于非连接态。
第一网络可以包括RAN-1和CN-1,第二网络包括RAN-2和CN-2。
S420、CN-1检测到有业务需要触发寻呼消息,则CN-1可以向RAN-1发送寻呼消息。触发寻呼消息的方式有两种:1、应用数据包;2、第三方服务器触发的请求消息。
该寻呼消息中可以携带业务信息,以便于终端设备根据业务信息,确定是否建立与第一网络的连接。业务信息可以包括业务类型和/或业务标识。
S430、RAN-1接收到CN-1发送的寻呼消息后,可以向终端设备发送寻呼消息。
S440、终端设备接收到寻呼消息后,可以根据寻呼消息中包括的业务信息,以及第二信息,确定是否建立与第一网络的连接。
第二信息可以包括以下信息中的至少一种:业务优先级,需要终端设备建立与第一网络的连接的业务和不需要终端设备建立与第一网络的连接的业务。
终端设备确定需要建立与第一网络的连接的情况下,可以断开与第二网络的连接,并使用USIM-1连接到第一网络上。
S450、终端设备向RAN-1发送第一请求消息,该第一请求消息可以为RRC连接建立请求消息,或该第一消息可以为RRC恢复请求消息。
如果终端设备与RAN-1处于RRC idle状态,则终端设备可以向RAN-1发送RRC连接建立请求消息;如果终端设备与RAN-1处于RRC非激活(inactive)状态,则终端设备可以向RAN-1发送RRC恢复请求消息。
终端设备发送第一请求消息时,可以在该第一请求消息中携带原因值,以指示终端设备是由于何种原因而发送的第一请求消息。该原因值可以包括SIM卡切换和/或特定业务的标识。
S460、RAN-1接收到终端设备发送的RRC连接建立请求消息后,可以向终端设备发送RRC建立(setup)消息;RAN-1接收到终端设备发送的RRC恢复请求消息后,可以向终端设备发送RRC恢复 (resume)消息。
S470、终端设备接收到RRC setup消息后,可以向RAN-1发送RRC建立完成消息;终端设备接收到RAN-1发送的RRC Resume消息后,可以向RAN-1发送RRC恢复完成消息。
S480、终端设备向CN-1发起NAS消息,如终端设备可以向CN-1发送业务请求消息或注册请求消息,以进入CM连接态。
本申请实施例还提供另一种无线通信方法,为支持多SIM卡的终端设备提供了一种确定是否进行SIM卡切换的方式。如图5所示,该方法包括步骤S510~S530。
与图3所示的方法不同的是,图5所示的方法是由网络侧来进行判断是否执行SIM卡切换,终端设备然后根据网络侧的决定来建立或不建立与第一网络的连接,能够最大化地降低终端设备的复杂度。图5所示的方法中的相应技术特征可以参见图3的描述,为了简洁,此处不再赘述。
S510、第一网络向终端设备发送第一消息。
该第一网络可以指第一网络设备,第一网络设备可以指核心网设备,或者可以指接入网设备。
终端设备可以为支持多SIM卡的终端设备,终端设备当前与第一网络处于非连接态,该第一网络可以为多个SIM卡中的一个SIM卡对应的网络。
例如,终端设备可以支持USIM-1和USIM-2,其中,USIM-1对应于第一网络,USIM-2对应于第二网络。终端设备当前处于与第一网络的非连接态,但是与第二网络处于连接态,也就是说,终端设备可以在第二网络上进行与USIM-2相关的数据业务,但是不能在第一网络上进行与USIM-1相关的数据业务。
终端设备接收到该第一消息后,可以执行S520的步骤,或者可以执行S530的步骤。终端设备具体执行哪个步骤,是根据网络侧的切换策略决定的。
该第一消息例如可以为寻呼消息,但本申请实施例并不限于此,当有业务触发时,第一网络也可以向终端设备发送其他消息。
当有业务触发时,第一网络可以向终端设备发送寻呼消息,以请求终端设备建立与第一网络的连接。第一网络向终端设备发送寻呼消息可以指,第一网络设在确定需要终端设备建立与第一网络的连接的情况下,向终端设备发送寻呼消息,或者可以指第一网络不论是否需要终端设备建立与第一网络的连接,都会向终端设备发送寻呼消息。
第一网络可以根据第一策略确定是否需要终端设备建立与第一网络的连接,第一策略可以包括以下信息中的至少一种:业务优先级、需要在寻呼消息中添加所述第一指示的业务、不需要在寻呼消息中添加所述第一指示的业务。
作为一种实现方式,第一网络可以根据第一策略和待传输的业务确定是否需要终端设备建立与第一网络的连接,待传输的业务可以理解为触发第一网络设备发送寻呼消息的业务。
第一网络可以根据待传输的业务的优先级,确定是否需要终端设备建立与第一网络的连接。或者,第一网络可以根据待传输的业务是否属于在寻呼消息中添加所述第一指示的业务,确定是否需要终端设备建立与第一网络的连接。
可选地,本申请实施例中的业务优先级可用于标识需要终端设备连接第一网络的业务和/或不需要终端设备连接第一网络的业务。
例如,该业务优先级可用于指示第一业务列表,该第一业务组为需要终端设备连接到第一网络的业务(如需要终端从空闲态或RRC-Inactive状态回到连接态),如果待传输的业务属于第一业务列表,则第一网络可以确定需要终端设备建立与第一网络的连接,如果待传输的业务不属于第一业务组,则第一网络可以确定不需要终端设备建立与第一网络的连接。又例如,该业务优先级可用于指示第二业务组,该第二业务组为不需要终端设备连接到第一网络的业务,如果待传输的业务属于第二业务组,则第一网络可以确定不需要终端设备建立与第一网络的连接,如果待传输的业务不属于第一业务组,则第一网络可以确定需要终端设备建立与第一网络的连接。再例如,该业务优先级可用于指示第一业务组和第二业务组,该第一业务组为需要终端设备连接到第一网络的业务,该第二业务组为不需要终端设备连接到第一网络的业务,如果待传输的业务属于第一业务组,则第一网络可以确定需要终端设备建立与第一网络的连接,如果待传输的业务属于第二业务组,则第一网络可以确定不需要终端设备建立与第一网络的连接。
第一策略在不同时间和/或不同地点下对应不同的信息。例如,第一策略包含不同时间和/或不同地点下的业务优先级,在不同时间和/或不同地点下,相同业务的优先级可以不同。又例如,在不同的时间和/或不同地点下,第二信息中包括的需要终端设备建立与第一网络的连接的业务不同。
业务优先级可以包括特定地点下的业务优先级和/或特定时间下的业务优先级,具体的情况可以参见上文的描述。
本申请实施例中的业务可以通过业务标识来表示。
本申请实施例中,第一网络可以根据用户面数据包中的业务标识来确定待传输的业务。
业务标识可以添加在IPv4/IPv6的用户面数据包的包头的差分服务代码点(differentiated services code point,DSCP)字段中。
当所述用户面数据包中的业务标识与所述第一策略的业务标识一致时,则第一网络可以使用该业务标识对应的策略来确定是否需要终端设备建立与第一网络的连接。例如,如果第一策略包括多个业务标识及其对应的优先级,则第一网络可以根据用户面数据包中的业务标识在第一策略中对应的优先级,确定是否需要终端设备建立与第一网络的连接。
本申请实施例对第一网络获取第一策略的方式不做具体限定,所述第一策略的全部或部分信息来自于以下中的至少一种:终端设备、签约信息和策略与计费控制(policy charging control,PCC)策略。
作为一个示例,终端设备可以向网络设备发送第一策略中的部分或全部信息。终端设备可以通过NAS消息向第一网络发送第一策略中的部分或全部信息,如终端设备可以在注册过程中和/或PDU会话建立过程中和/或PDU会话修改过程中向第一网络发送或更新第一策略中的部分或全部信息。
作为又一示例,统一数据管理(unified date management,UDM)网元可以向第一网络发送签约信息,该签约信息中可以携带第一策略中的部分或全部信息。UDM网元可以在终端设备的注册过程中和/或PDU会话建立过程中和/或PDU会话修改过程中,向第一网络发送或更新第一策略中的部分或全部信息。
作为再一示例,策略控制功能(policy control function,PCF)网元可以向第一网络发送PCC策略,该PCC策略中可以携带第一策略中的部分或全部信息。PCF网元可以在终端设备的注册过程中和/或PDU会话建立过程中和/或PDU会话修改过程中,向第一网络发送或更新第一策略中的部分或全部信息。
S520、终端设备响应于该第一消息,建立与第一网络的连接。
在该情况下,第一网络只有在确定需要终端设备建立与第一网络的连接的情况下,才会向终端设备发送第一息,否则第一网络不向终端设备发送第一消息。
S530、终端设备根据第一消息,确定是否建立与第一网络的连接。
该第一消息中可以包括指示信息,该指示信息用于指示是否需要终端设备建立与第一网络的连接,终端设备可以根据该指示信息,建立或不建立与第一网络的连接。
例如,如果该指示信息指示需要终端设备建立与第一网络的连接,则终端设备接收到该指示信息后,建立与第一网络的连接;如果该指示信息指示不需要终端设备建立与第一网络的连接,则终端设备接收该指示信息后,不建立与第一网络的连接,终端设备可以继续停留在当前的处于连接态的网络上。
该指示信息可以通过比特位来指示,例如可以通过1个比特位来指示该指示信息。如果该比特位取值为0,表示不需要终端设备建立与第一网络的连接;如果该比特位取值为1,表示需要终端设备建立与第一网络的连接。
又例如,终端设备可以根据第一消息中是否携带第一指示,确定是否建立与第一网络的连接。如果第一消息携带第一指示,表示终端设备需要建立与第一网络的连接;如果第一消息中没有携带第一指示,则表示终端设备不需要建立与第一网络的连接。该第一指示是在第一网络确定需要终端设备建立与第一网络的连接的情况下发送的。
在有业务触发第一网络向终端设备发送第一消息时,第一网络可以确定是否需要终端设备建立与第一网络的连接。当需要终端设备建立与第一网络的连接的情况下,第一网络在第一消息中携带第一指示;当不需要终端设备建立与第一网络的连接的情况下,第一网络不在第一消息中携带第一指示。终端设备接收到第一网络发送的第一消息后,可以先判断该第一消息中是否携带第一指示,如果该第一消息中携带第一指示,则终端设备建立与第一网络的连接,如果该第一消息中没有携带第一指示,则终端设备不建立与第一网络的连接。
可选地,如图8所示,终端设备可以向网络设备发送第二指示,该第二指示用于指示第一网络根据第一策略和/或待传输的业务确定是否需要终端设备建立与第一网络的连接。第一网络接收到终端设备发送的第二指示后,根据上文描述的方式确定是否需要终端设备建立与第一网络的连接。如,终端处于CM-IDLE状态或RRC-Inactive状态时,第一网络会对发送给终端设备的数据包进行检测,如果有下行的特定业务的数据包触发寻呼(如根据业务优先级进行确定),第一网络根据特定业务确定需要向终端设备发送寻呼消息(如图6的S603-1所示),或在寻呼消息中携带第一指示(如图6的S603-2所示),或在寻呼消息中携带业务信息(如图4的S420所示),如UE处于RRC-Inactive状态还会结合图7所示方式执行。
如果第一网络没有接收到终端设备发送的第二指示,则不会对发送给终端设备的数据包进行检测,而是只要有业务触发寻呼,第一网络都将该寻呼消息发送给终端设备。
第二指示例如可以是在终端设备决定离开第一网络或决定断开与第一网络的连接的情况下发送给第一网络的。
举例说明,以终端设备刚开始与第一网络连接,之后切换到第二网络,然后再由第二网络切换到第一网络的过程为例,终端设备刚开始使用USIM-1与第一网络连接,由于需要使用USIM-2连接至第二网络执行业务-1(如语音业务),由于终端能力的限制(只能与一个网络进行发送和接收数据),终端设备需要断开与第一网络的连接。在该情况下,终端设备可以向第一网络发送第二指示。在该情况下,第一网络根据第二指示开启上文描述的方法进行判断,如果第一网络上有业务需要传输,则第一网络可以根据上文描述的方法进行判断,确定是否需要终端设备建立与第一网络的连接。如果第一网络没有接收到终端设备发送的第二指示,则第一网络可以不用执行上文描述的方法,可不进行判断,直接将寻呼消息发送给终端设备。
如果终端设备完成业务-1后,从所述USIM-2又切换回USIM-1,即断开USIM-2与第二网络的连接并通过USIM-1与第一网络建立连接(如RRC连接),终端可以向第一网络发送第三指示(如图9所示),第三指示可用于指示第一网络停止根据第一策略和/或待传输的业务确定是否需要终端设备建立与第一网络的连接。第一网络在收到第三指示的情况下,可以根据第三指示停止上文描述的方法。
可选地,本申请实施例中的第二指示或第三指示可以是终端设备通过NAS消息或RRC消息发送给第一网络的。若为RRC消息发送,则RAN节点接收到“第二指示”或“第三指示”后,可以进一步发送给核心网节点(如AMF、SMF)。
下面结合图6,以第一消息为寻呼消息为例,对本申请实施例的无线通信方法进行详细描述。图6所示的方法包括步骤S601~S10。
S601、终端设备的USIM-1在第一网络上完成注册或附着,终端设备的USIM-2在第二网络上完成注册或附着。终端设备当前与第二网络处于CM连接态,与第一网络处于非连接态。
第一网络可以包括RAN-1和CN-1,第二网络包括RAN-2和CN-2。
S602、CN-1检测到有业务需要触发寻呼消息。触发寻呼消息的方式有两种:1、应用数据包;2、第三方服务器触发的请求消息。
CN-1可以确定触发寻呼消息的业务属于哪个业务,例如CN-1确定触发寻呼消息的业务为业务-1。
如果是应用数据包触发的寻呼消息,则CN-1可以执行流量检测功能,确定该数据包对应的是业务-1。该过程可以是由CN-1中的用户面网元执行的。
如果是第三方服务器触发的寻呼消息,该过程可以是第三方服务器通过控制面向控制面网元发送请求消息,以触发CN-1向终端设备发送寻呼消息,该控制面网元例如可以是PCF网元。
CN-1可以根据业务信息,确定是否需要终端设备建立与第一网络的连接。
参见上文的描述,CN-1可以根据业务信息,以及第二信息,确定是否需要终端设备建立与第一网络的连接。
该第二信息可以理解为一种策略,该第二信息可以包括以下信息中的至少一种:业务优先级,需要终端设备建立与第一网络的连接的业务,和不需要终端设备建立与第一网络的连接的业务。
CN-1根据业务信息和第二信息,确定是否需要终端设备建立与第一网络的连接的方式与图3所示的终端设备根据第一信息和第二信息,确定是否需要建立与第一网络的方式类似,此处不再赘述。
本申请实施例中,CN-1向终端设备指示是否需要建立与第一网络的连接的方式有两种,分别是步骤S603-1和步骤S603-2中描述的方式。
S603-1、CN-1根据判断结果,确定是否需要向终端设备发送寻呼消息。如果CN-1确定需要终端设备建立与第一网络的连接,则CN-1可以向终端设备发送寻呼消息;如果CN-1确定不需要终端设备建立与第一网络的连接,则CN-1可以不向终端设备发送寻呼消息。
类似地,如果CN-1采用寻呼消息直接指示是否需要终端设备建立与第一网络的连接,则只要终端设备接收到寻呼消息,就建立与第一网络的连接;如果终端设备没有接收到寻呼消息,则终端设备就不建立与第一网络的连接。
S603-2、CN-1可以根据判断结果确定是否需要在寻呼消息中添加第一指示。在该情况下,不论是否需要终端设备建立与第一网络的连接,CN-1都会向终端设备发送寻呼消息,只不过会将判断结果通过第一指示来指示给终端设备。
如果CN-1确定需要终端设备建立与第一网络的连接,则CN-1可以在寻呼消息中添加第一指示;如果CN-1确定不需要终端设备建立与第一网络的连接,则CN-1可以不在寻呼消息中添加第一指示。
类似地,如果CN-1采用第一指示的方式来指示终端设备是否需要建立与第一网络的连接,则终端设备在接收到寻呼消息后,会根据寻呼消息中是否携带第一指示,来确定是否建立与第一网络的连接。如果寻呼消息中包括第一指示,则终端设备建立与第一网络的连接;如果寻呼消息中没有携带第一指示, 则终端设备不建立与第一网络的连接。
本申请实施例中,CN-1向终端设备发送寻呼消息,可以指CN-1通过RAN-1向终端设备发送寻呼消息。也就是说,CN-1可以向RAN-1发送寻呼消息,RAN-1根据CN-1发送的寻呼消息,向终端设备发送寻呼消息。
S604、CN-1根据S603-1或S603-1的判断结果,向RAN-1发送寻呼消息,或在寻呼消息中携带第一指示。
S605、RAN-1接收到CN-1发送的寻呼消息后,向终端设备发送寻呼消息。
RAN-1可以将CN-1发送的寻呼消息透传给终端设备。
S606、终端设备接收到RAN-1发送的寻呼消息后,根据寻呼消息的指示,建立或不建立与第一网络的连接。
终端设备在连接到第二网络的情况下,仍然照常在指定的时间点监视SIM-1的寻呼请求消息,即监听RAN-1是否向终端设备发送了寻呼消息。
如果寻呼消息是按照步骤S603-1的策略发送的,则终端设备设备接收到寻呼消息后,就可以建立与第一网络的连接。
如果寻呼消息是按照步骤S603-2的策略发送的,则终端设备接收到寻呼消息后,可以先判断该寻呼消息中是否携带第一指示。如果该寻呼消息中携带第一指示,则终端设备建立与第一网络的连接;如果该寻呼消息中未携带第一指示,则终端设备不建立与第一网络的连接。
如果终端设备确定需要建立与第一网络的连接,则终端设备可以执行步骤S670。
S607、终端设备向RAN-1发送第一请求消息,该第一请求消息可以为RRC连接建立请求消息,或该第一消息可以为RRC恢复请求消息。
如果终端设备与RAN-1处于RRC idle状态,则终端设备可以向RAN-1发送RRC连接建立请求消息;如果终端设备与RAN-1处于RRC inactive状态,则终端设备可以向RAN-1发送RRC恢复请求消息。
终端设备发送第一请求消息时,可以在该第一请求消息中携带原因值,以指示终端设备是由于何种原因而发送的第一请求消息。该原因值可以包括SIM卡切换和/或特定业务的标识。
S608、RAN-1接收到终端设备发送的RRC连接建立请求消息后,可以向终端设备发送RRC建立(setup)消息;RAN-1接收到终端设备发送的RRC恢复请求消息后,可以向终端设备发送RRC恢复(resume)消息。
S609、终端设备接收到RRC setup消息后,可以向RAN-1发送RRC建立完成消息;终端设备接收到RAN-1发送的RRC Resume消息后,可以向RAN-1发送RRC恢复完成消息。
S610、终端设备向CN-1发起NAS消息,如终端设备向CN-1发送业务请求消息或注册请求消息,以进入CM连接态。
第一网络确定是否需要终端设备建立与第一网络的连接的方式与上文描述的终端设备确定是否需要建立与第一网络的连接的方式类似。
第一网络可以根据业务信息,确定是否需要终端设备建立与第一网络的连接。第一网络设备可以根据业务信息的重要程度,确定是否需要终端设备建立与第一网络的连接。
例如,第一网络可以根据业务信息,以及第二信息,确定是否需要终端设备建立与第一网络的连接。该第二信息可以包括以下信息中的至少一种:业务优先级,需要终端设备建立与第一网络的连接的业务,不需要终端设备建立与第一网络的连接的业务。
为了简洁,此处不再赘述。
如上文描述,当第一网络接收到应用数据包或者第三方服务器触发的请求消息时,第一网络可以向终端设备发送寻呼消息。
该寻呼消息可以是接入网设备发送给终端设备的,如接入网设备可以通过空口向终端设备发送寻呼消息。
接入网设备可以根据第三消息向终端设备发送寻呼消息,该第三消息可以是来自于核心网控制面设备或用户面设备,也就是说,核心网设备可以通过用户面设备或控制面设备向接入网设备发送第三消息。
该第三消息可以包括第一指示和/或业务标识。
作为一个示例,如果决策是由终端设备执行的,则当有业务触发核心网设备发送第三消息时,核心网设备可以直接向接入网设备发送第三消息,并将业务标识添加在第三消息中。
作为又一示例,如果决策是由网络设备执行的,则当有业务触发核心网设备发送第三消息时,核心网设备可以根据该业务及第一策略,确定是否需要终端设备建立与第一网络的连接,如果需要终端设备 建立与第一网络的连接,则核心网设备可以在第三消息中添加第一指示,并将添加第一指示的第三消息发送给接入网设备。
如图7所示,与SIM-1对应的网络设备包括RAN-1和CN-1,与SIM-2对应的网络设备包括RAN-2和CN-2。终端设备可以通过SIM-1与RAN-1和/或CN-1进行通信,终端设备可以通过SIM-2与RAN-2和/或CN-2进行通信。
图7所示的方法包括步骤S710和S720。
S710、CN-1向接入网设备发送第三消息。当有业务到达第一网络时,CN-1可以向接入网设备发送第三消息。
S720、RAN-1接收到CN-1发送的第三消息后,可以向终端设备发送寻呼消息。该寻呼消息可以指上文描述的第一消息。
第三消息可以为寻呼消息,也可以为GPRS隧道协议(GPRS tunnelling protocol,GTP-U)消息。例如,核心网控制面设备向接入网设备发送的第三消息可以为寻呼消息。又例如,用户面设备向接入网设备发送的第三消息可以为GTP-U消息。
如果终端设备与第一网络处于CM-idle状态,在该情况下,终端设备与接入网设备之间的空口,以及接入网设备与核心网设备之间的N2接口都处于释放的状态,那么核心网向接入网发送的第三消息为寻呼消息,接入网设备向终端设备发送的第一消息为寻呼消息。核心网设备向接入网设备发送寻呼消息时可以通过控制面设备来发送。
如果终端设备与第一网络处于RRC-inactive状态,在该情况下,终端设备与接入网设备之间的空口释放,但是接入网设备与核心网设备之间的N2接口未释放,那么就不会触发核心网设备向接入网设备发送寻呼消息。当有业务到达时,核心网设备可以通过用户面设备向接入网设备发送GTP-U消息,接入网设备收到用户面数据后向终端设备发送寻呼消息。
不论核心网设备向接入网设备发送的第三消息是寻呼消息还是GTP-U消息,该寻呼消息或GTP-U消息均可以包括第一信息,以便于终端设备根据第一信息,确定是否建立与第一网络的连接。
寻呼消息中包括的第一信息和/或第一指示可以是以UE ID为粒度进行发送的。
一个UE ID可以对应一个USIM,例如一个UE ID可以对应一个订阅永久标识符(SUbscription Permanent Identifier,SUPI)或全球唯一临时UE标识(Globally Unique Temporary UE Identity,GUTI)
以第一消息包括业务信息为例,每一个业务信息都有一个对应的业务信息,终端设备接收到寻呼消息后,可以寻找自己的UE ID对应的业务信息,然后根据该业务信息,确定是否建立与第一网络的连接。
又如,
针对图7所示的两个阶段的寻呼消息,分别对第一信息和第一指示的添加位置进行描述。关于第一信息和第一指示的含义可以参见上文的描述。第一信息和第一指示可以是服用现有的寻呼消息中的字段进行指示,也可以是在现有的寻呼消息中重新添加一个字段来指示。
对于S710中的寻呼消息,CN-1向RAN-1发送的寻呼消息的格式如表4所示。
表4
Figure PCTCN2019115428-appb-000003
其中,TAI表示UE的跟踪区域标识(tracking area identity,TAI),IE表示信息单元(information element,IE)。
第一信息可以添加在用于寻呼的服务数据(Assistance Data for Paging)的字段中,如表4所示的选择1;第一信息还可以是添加在一个新的参数中,如表4所示的选择2,在表4所示的寻呼消息中,通过新添加一个字段用于指示第一信息
第一指示可以添加在寻呼优先级(Paging Priority)的字段中,如表4所示的选择1;第一指示还可以添加在一个新的参数中,如表4所示的选择2,在表4所示的寻呼消息中,通过新添加一个字段用于指示第一指示。
CN-1发送给RAN-1的寻呼消息可以是以UE ID为粒度的,一条寻呼消息可用于同时寻呼多个终端设备。CN-1通过寻呼消息携带第一信息和/或第一指示时,可以通过UE ID来标识发送给不同的终端设备的第一信息和/或第一指示。
对于S720中的寻呼消息,RAN-1向终端设备发送的寻呼消息的格式可以如下所示。
Figure PCTCN2019115428-appb-000004
第一信息可以添加在寻呼记录(Paging Record)的字段中,该寻呼记录中包括多个终端设备的第一信息,可以通过UE-ID区分不同的终端设备的第一信息,其中,每一个UE-ID都有一个对应的第一信息。
第一指示也可以添加在“Paging Record”的字段中,在Paging Record中通过一个新的取值来实现;或者第一指示可以是在寻呼消息中重新添加一个参数来指示。
RAN-1发送给终端设备的寻呼消息,一条寻呼消息可用于同时寻呼多个终端设备。因此,第一信息和第一指示可以是以UE-ID为粒度进行发送的,这样,终端设备接收到寻呼消息后,可以根据自己的UE-ID对应的业务标识和/或第第一指示,确定是否建立与第一网络的连接。
本申请实施例通过复用现有的流程向终端设备传输第二信息,以及复用现有的寻呼消息中的字段来传输第一信息和/或第一指示,能够减少整个系统的额外复杂度。
本申请实施例中的终端设备支持多SIM卡,可以指终端设备支持两个或两个以上的SIM卡。该SIM卡可以指普通的SIM卡,也可以指USIM卡。
