终端(UE,User Equipment)、无线接入网(RAN,Radio Access Network)、用户平面功能(UPF,User Plane Function)、数据网络(DN,Data Network)、接收核心接入和移动性管(AMF,Core Access and Mobility Management Function)、会话管理功能(SMF,Session Management Function)、策略控制功能(PCF,Policy Control function)、应用功能(AF,Application Function)、鉴权服务器功能(AUSF,Authentication Server Function)、统一数据管理(UDM,Unified Data Management)。

上述图1、图2的例子只是实现本发明实施例的一个网络架构实例,本发明实施例并不限于上述图1、图2所述的网络结构。
图3为本发明实施例的触发网络切换的方法的流程示意图一,如图3所示,所述触发网络切换的方法包括以下步骤:
步骤301:第一核心网网元判定出满足切换条件时,向基站发送切换请求消息,所述切换请求消息用于触发所述基站执行终端的网络切换过程或会话修改过程。
具体实现时,第一核心网网元通过其他核心网网元向基站发送切换请求消息,以第一核心网网元为PCF为例,PCF通过AMF/MME网元向基站发送切换请求消息,参照图15,AMF/MME网元向RAN(对应基站)发送切换请求消息。
这里,第一核心网网元判定满足切换条件可以通过但不局限于以下方式来实现:
1)所述第一核心网网元确定出所述终端在第一网络上的使用流量超过预设阈值时,向所述基站发送切换请求消息。
具体地,所述第一核心网网元接收第二核心网网元发送的第一触发消息,所述第一触发消息用于指示所述终端在第一网络上的使用流量超过预设阈值。
2)所述第一核心网网元确定出所述终端在第一网络上正在使用一种或多种特定的应用时,向所述基站发送切换请求消息。
在一实施方式中,所述特定的应用,包括以下至少之一:
所述第一网络不支持的应用、占用所述第一网络的资源超过预设值的应用、签约信息中要求不在所述第一网络上使用的应用、签约信息中处于低优先级传递数据包的应用,所述低优先级传递数据包是指传递数据包的优先级低于或等于预设优先级。
在签约信息中包括多个应用对应的属性信息,所述属性信息包括以下至少之一:特征信息、服务优先级信息、重要程度信息;
所述第一核心网网元根据当前正在进行的应用,选择重要程度最高的应用对应的服务优先级,根据该服务优先级确定是否触发网络切换过程或会话修改过程;或者,
所述第一核心网网元根据当前正在进行的一个或多个应用,计算出每个服务优先级对应的重要程度总和,根据各个服务优先级对应的重要程度总和确定是否触发网络切换过程或会话修改过程。
具体实现时,可以在签约信息中增加一个签约信息列表,包含多个应用对应的特征信息、服务优先级信息、重要程度信息(这里的有些信息是可选的,例如重要程度信)等等,网络网元根据该签约信息列表来判断是否触发切换,一个例子如表1所示。
Figure PCTCN2018086390-appb-000001
表1
重要程度为一个范围,比如1-15,服务优先级可以是一个值或多个值。
网络侧根据正在进行的应用,选择重要程度最高的那个应用对应的服务优先级,按其来决定是否触发网络切换或会话修改。或者,
网络侧也根据当前正在进行的一个或多个应用,计算出每一个服务优先级对应的重 要程度总和,比如当前正在进行的应用为如下三个:
应用-1 特征信息1 服务优先级[NR-5GC] 重要程度12
应用-2 特征信息2 服务优先级[NR-5GC] 重要程度5
应用-3 特征信息3 服务优先级[LTE-EPC] 重要程度8
…… …… …… ……
表2
网络侧计算出[NR-5GC]的重要程度总和为12+5=17,[LTE-EPC]的重要程度总和为8,因此若UE只支持单注册,则选择[NR-5GC]作为当前工作的网络;若UE支持双注册,则可以将应用-3的数据流切换到LTE-EPC下,而应用-1和2的仍然传输在NR-5GC下。
上述规则可以由PCF来使用,也可以由PCF或UDM下发给其他网元如SMF来使用。
3)所述第一核心网网元确定出所述终端移动进入目标区域或者移动离开目标区域时,向所述基站发送切换请求消息。
4)所述第一核心网网元接收到第二触发消息时,向所述基站发送切换请求消息。
在一实施方式中,所述第一核心网网元接收到第三核心网网元发送的切换请求消息。这种情况下,所述第一核心网网元向所述基站发送切换请求消息。
在另一实施方式中,所述第一核心网网元接收到终端发送的服务请求消息,所述服务请求消用于指示特定业务(如紧急呼叫业务、语音呼叫业务)的发生或请求切换。这种情况下,所述第一核心网网元向所述基站发送切换请求消息。
上述方案中,所述切换请求消息用于指示所述基站执行终端的一部分或全部用户面数据流由第一网络切换到第二网络的切换过程。
在一实施方式中,所述切换请求消息包括以下至少一种指示信息:
基于跨系统接口切换的指示信息;
基于无跨系统接口重定向的指示信息;
会话建立/修改请求指示信息;
将指定的应用数据流和/或会话进行切换的指示信息。
进一步,如果所述切换请求消息包括所述将指定的应用数据流和/或会话进行切换的指示信息,则所述切换请求消息还包括:
将指定的数据流和/或会话从当前的连接第一核心网的第一基站切换到连接第二核心网的第二基站上的指示信息;或,
将指定的数据流和/或会话从当前的连接第一核心网的第一基站切换到连接第一核心网的第二基站上的指示信息。
参照图16,第一核心网网元为AMF或SMF,基站对应的接入网为RAN-1,其中,RAN-1和AMF/SMF属于第一网络(也即5G网络),RAN-2和MME属于第二网络(也即4G网络),AMF/SMF向RAN-1发送的切换请求消息中携带指定的应用数据流和/或会话的标识信息(Flow id list和/或Session id list)以及连接的目标RAT=RAN-2和目标核心网为EPC,RAN-1向UE发送的空口消息也即AS层消息(例如RRC连接重配置消息或RRC连接释放消息)中携带指定的应用数据流和/或会话的标识信息(Flow id list和/或Session id list),之后,UE向RAN-2发送AS层消息,并向MME发送会话建立消息(如附着请求消息或位置更新消息),在会话建立消息中携带指定的应用数据流和/或会话的标识信息(Flow id list和/或Session id list),进一步还可以携带其他指示信息,之后,第二网络侧开始执行相应的应用数据流和/或会话的建立。
参照图17,第一核心网网元为AMF或SMF,基站对应的接入网为RAN-1,其中, RAN-1和RAN-2均属于第一网络(也即5G网络),AMF/SMF向RAN-1发送的切换请求消息中携带指定的应用数据流和/或会话的标识信息(Flow id list和/或Session id list)以及连接的目标RAT=RAN-2和目标核心网为5GC,RAN-1在空口与UE交互(通过RRC Connection Reconfiguration消息),将指定的Flow/PDU Session对应的空口无线承载切换到目标RAN-2侧,然后回复核心网AMF/SMF转移成功的Flow id和/或PDU session id列表。

这里,切换请求消息携带网络切换类型,例如:RAT切换、或者EPS切换。
步骤704:UE与网络侧各网元执行切换过程。
采用本发明实施例的技术方案,使得PCF在得知UE在5G网络下的使用流量达到上限的情况下,立刻触发UE返回到4G网络。
以下基于4G网络架构,提出本发明各个实施例。
图8为本发明实施例的触发网络切换的方法的流程示意图六,如图8所示,所述触发网络切换的方法包括以下步骤:
步骤801:PCRF网元确定所述终端在4G网络上的使用流量是否超过预设阈值。
在一实施方式中,所述PCF网元接收MME网元/PDN-GW网元发送的第一触发消息,所述第一触发消息用于指示所述终端在4G网络上的使用流量超过预设阈值。
步骤802:PCRF网元确定出所述终端在4G网络上的使用流量超过预设阈值时,向eNB发送切换请求消息。
本发明实施例中,所述切换请求消息用于指示所述eNB执行终端由4G网络切换到3G网络的切换过程。

步骤1001:PCRF网元确定是否接收到第二触发消息。
在一实施方式中,如果所述PCRF网元接收到AF网元发送的切换请求消息时,则确定接收到第二触发消息。
步骤1002:所述PCRF网元接收到第二触发消息时,向eNB发送切换请求消息。
本发明实施例中,所述切换请求消息用于指示所述eNB执行终端由4G网络切换到3G网络的切换过程。
图11为本发明实施例的触发网络切换的方法的流程示意图九,如图11所示,所述触发网络切换的方法包括以下步骤:
步骤1101.1:UE向AMF/MME网元发送业务请求消息。
这里,UE上报的业务请求消息可以通过目前的Service request消息实现,可以指示请求的业务类型,如紧急呼叫业务、语音呼叫业务等等。
步骤1101.2:SMF/PGW网元向PCF进行事件上报。
这里,事件上报包括:用量检测、应用检测等等。
步骤1101.3:AF向PCF发送切换请求消息。
这里,AF发送的切换请求消息作为第三方触发请求是由第三方服务器来主动触发的。
上述步骤1101.1、步骤1101.2、步骤1101.3均可以触发切换过程,可以单独执行,也可以并列执行。
步骤1102:PCF网元向AMF/MME网元发送切换请求消息。
步骤1103:AMF/MME网元向RAN发送切换请求消息,以触发切换过程。
上述方案中仅以终端由5G网络切换到4G网络,或者由4G网络切换到3G网络为例,实际应用中,网络的切换并不局限于此,任何基于本发明实施例技术方案的思想所实现的网络切换均属于本发明实施例保护的范围。
