为了使本发明的目的、技术方案和优点更加清楚,下面结合附图和具体实施例对本发明进行详细描述。
本发明的核心思想在于,在切换要求消息中携带切换类型信息,以
指示移动性管理设备触发对应类型的切换。其中,切换要求消息中可以携带的切换类型可以包括但不限于:RAT切换、System切换或Circuit Switch(电路域切换)。
本发明适用于不同类型网络之间的切换,例如本发明既适用于从5G到4G的切换,也适用于从4G到5G的切换。下面分别结合实施例进行详细描述。
实施例一、
图2为本发明实施例一提供的方法流程图,该实施例以从5G到4G的切换的场景为例。如图2所示,该方法可以包括以下步骤:
在201中,NG-RAN在向AMF发送的HO Required(切换要求)消息中携带HO type(切换类型)信息。
若NG-RAN检测到网络侧不支持UE所请求的业务,例如接入网不支持UE所请求的业务,或者核心网不支持UE所请求的业务,则由NG-RAN主动向AMF发送HO Required消息。
在NG-RAN向AMF发送的HO Required消息中,NG-RAN可以确定本次切换所采用的切换类型,该切换类型必须是核心网侧设备(例如目标eNB)所支持的。然后将确定本次切换所采用的切换类型信息携带在HO Required消息中发送给AMF。其中,切换类型信息可以在HO Required消息中采用一个字段进行表示,具体表示形式本发明并不加以限制,例如可以采用00表示RAT切换,采用01表示System切换,采用10表示Circuit Switch切换。对于该字段可以进行扩展,以支持后续出现的其他类型的切换方式。
在202中,AMF依据HO Required消息中携带的HO type信息,确
定触发的切换类型,并触发对应的切换。
AMF对HO Required消息进行解析并触发切换的情况具体可以包括但不限于以下几种:
第一种情况:AMF解析HO Required消息,若解析得到HO type信息,则触发HO type信息所指示的切换。
若解析得到的HO type信息指示进行RAT HO切换,则AMF触发RAT HO切换。RAT HO切换时,5GC不变,接入的基站从gNB切换至eNB,具体切换至哪个eNB可以依据HO Required消息中携带的目标基站标识确定。
若解析得到的HO type信息指示进行系统切换,则AMF触发系统切换。系统切换时,接入的核心网从5GC切换至EPC,同时接入的基站切换至eNB,具体切换至哪个eNB可以依据HO Required消息中携带的目标基站标识确定。
若解析得到的HO type信息指示进行Circuit Switch切换,则AMF触发Circuit Switch切换。Circuit Switch切换时,进行MSC(移动交换中心)的切换。
需要说明的是,一旦AMF触发了特定类型的切换,后续切换流程本发明实施例并不加以限制,可以采用现有的RAT切换、系统切换、Circuit Switch切换流程。
第二种情况:若从HO Required消息中未解析得到HO type信息,但解析得到业务类型(Service type)信息,且核心网支持该业务,则触发RAT切换。或者,
若从HO Required消息中未解析得到HO type信息,但解析得到业
务类型(Service type)信息,且核心网支持该业务以及用户签约了该业务,则触发RAT切换。
HO Required中携带的Service type信息通常是UE所采用的特殊业务的类型,例如紧急呼叫业务等,对于此类特殊业务,如果接入网和核心网都支持并签约了该业务,则触发RAT切换。
第三种情况:若从HO Required消息中未解析得到HO type信息和Service type信息,且AMF与HO Required携带的目标基站标识对应的目标基站连接,则触发RAT切换。
第四种情况:若以上三种情况均不满足,例如若从HO Required消息中未解析得到HO type信息和Service type信息,且AMF与HO Required消息携带的目标基站标识对应的目标基站未连接,则触发系统切换。
实施例二、
图3为本发明实施例二提供的方法流程图,该实施例同样用于从5G到4G的切换。如图3所示,该方法可以包括以下步骤:
在301中,UE在向AMF发送的Service Request(服务请求)消息中携带HO type(切换类型)信息。
在一些情况下,切换要求由UE主动触发,则UE可以发送Service Request以指示网络做切换,同时指示HO Type。
这种情况下,就需要UE预先知道网络侧支持的HO Type以及业务类型(Service Type),在本发明实施例中,可以在UE的网络注册过程中由NG-RAN将接入网侧设备支持的HO Type信息和/或Service Type信息发送给AMF,再进一步由AMF将网络侧支持的HO Type信息和/
或Service Type信息提供给UE。具体地过程可以如图4中所示。
当UE发起网络注册后,NG-RAN可以在向AMF发送的Registration Request(注册请求)消息中携带接入网侧设备支持的HO Type信息和/或Service Type信息。中间的注册过程在图4中未示出,直至完成注册AMF向UE发送Registration Accept(注册接受)消息时,在Registration Accept消息中携带网络侧支持的HO Type信息和/或Service Type信息。然后UE获得并保存网络侧支持的HO Type信息和/或Service Type信息。当UE发送Service Request消息以指示网络侧进行切换时,从网络侧支持的HO Type中选择本次切换所采用的HO Type,并将其携带于Service Request消息中。
另外,在上述Registration Accept消息中携带网络侧对业务类型的支持状况时,例如采用00表示仅核心网支持UE的特殊业务类型,01表示核心网和接入网都不支持UE的特殊业务类型,10表示核心网和接入网都支持UE的特殊业务类型。
继续参见图3,在302中,AMF向NG-RAN发送N2Request for HO(通过N2接口发送的切换请求)消息,该N2Request for HO消息中携带HO type信息。
在203中,NG-RAN在向AMF发送的HO Required消息中携带HO type信息。
在本发明实施例中,可以通过在Service Request消息、N2Request for HO消息和HO Required消息中采用一个字段进行表示,具体表示形式本发明并不加以限制,例如可以采用00表示RAT切换,采用01表示System切换,采用10表示Circuit Switch切换。对于该字段可以进行扩展,以
支持后续出现的其他类型的切换方式。
在304中,AMF依据HO Required消息中携带的HO type信息,确定触发的切换类型。
本步骤与实施例一中步骤202相同,具体参见实施例一中关于步骤202的描述,在此不做赘述。
实施例三、
图5为本发明实施例三提供的方法流程图,该实施例用于从4G到5G的切换。如图5所示,该方法可以包括以下步骤:
在501中,E-UTRAN(4G的接入网侧设备)在向MME(4G的移动管理设备)发送的HO Required(切换要求)消息中携带HO type(切换类型)信息。
若E-UTRAN检测到网络侧不支持UE所请求的业务,例如接入网不支持UE所请求的业务,或者核心网不支持UE所请求的业务,则由E-UTRAN主动向MME发送HO Required消息。
在E-UTRAN向MME发送的HO Required消息中,E-UTRAN可以确定本次切换所采用的切换类型,该切换类型必须是核心网侧设备(例如目标gNB)所支持的。然后将确定本次切换所采用的切换类型信息携带在HO Required消息中发送给MME。其中,HO Type信息可以在HO Required消息中采用一个字段进行表示,具体表示形式本发明并不加以限制,例如可以采用00表示RAT切换,采用01表示System切换,采用10表示Circuit Switch切换。对于该字段可以进行扩展,以支持后续出现的其他类型的切换方式。
在502中,MME依据HO Required消息中携带的HO type信息,确
定触发的切换类型,并触发对应的切换。
MME对HO Required消息进行解析并触发切换的情况具体可以包括但不限于以下几种:
第一种情况:MME解析HO Required消息,若解析得到HO type信息,则触发HO type信息所指示的切换。
若解析得到的HO type信息指示进行RAT HO切换,则MME触发RAT HO切换。RAT HO切换时,4GC不变,接入的基站从eNB切换至gNB,具体切换至哪个gNB可以依据HO Required消息中携带的目标基站标识确定。
若解析得到的HO type信息指示进行系统切换,则MME触发系统切换。系统切换时,接入的核心网从EPC切换至5GC,同时接入的基站切换至gNB,具体切换至哪个gNB可以依据HO Required消息中携带的目标基站标识确定。
若解析得到的HO type信息指示进行Circuit Switch切换,则MME触发Circuit Switch切换。Circuit Switch切换时,进行MSC(移动交换中心)的切换。
需要说明的是,一旦MME触发了特定类型的切换,后续切换流程本发明实施例并不加以限制,可以采用现有的RAT切换、系统切换、Circuit Switch切换流程。
第二种情况:若从HO Required消息中未解析得到HO type信息,但解析得到业务类型(Service type)信息,且核心网支持该业务,则触发RAT切换。或者,
若从HO Required消息中未解析得到HO type信息,但解析得到业
务类型(Service type)信息,且核心网支持该业务以及用户签约了该业务,则触发RAT切换。
HO Required中携带的Service type信息通常是UE所采用的特殊业务的类型,例如紧急呼叫业务等,对于此类特殊业务,如果接入网和核心网都支持并签约了该业务,则触发RAT切换。
第三种情况:若从HO Required消息中未解析得到HO type信息和Service type信息,且MME与HO Required携带的目标基站标识对应的目标基站连接,则触发RAT切换。
第四种情况:若以上三种情况均不满足,例如若从HO Required消息中未解析得到HO type信息和Service type信息,且MME与HO Required消息携带的目标基站标识对应的目标基站未连接,则触发系统切换。
实施例四、
图6为本发明实施例四提供的方法流程图,该实施例同样用于从4G到5G的切换。如图6所示,该方法可以包括以下步骤:
在601中,UE在向MME发送的Service Request(服务请求)消息中携带HO type(切换类型)信息。
在一些情况下,切换要求由UE主动触发,则UE可以发送Service Request以指示网络做切换,同时指示HO Type。
这种情况下,就需要UE预先知道网络侧支持的HO Type以及业务类型(Service Type),在本发明实施例中,可以在UE的网络注册过程中由E-UTRAN将接入网侧设备支持的HO Type信息以及业务类型(Service Type)发送给MME,再进一步由MME将网络侧支持的HO
Type信息和/或Service Type信息提供给UE。具体地过程可以如图7中所示。
当UE发起网络注册后,E-UTRAN可以在向MME发送的Registration Request(注册请求)消息中携带接入网侧设备支持的HO Type信息和/或Service Type信息。中间的注册过程在图7中未示出,直至完成注册MME向UE发送Registration Accept(注册接受)消息时,在Registration Accept消息中携带网络侧支持的HO Type信息和/或Service Type信息。然后UE获得并保存网络侧支持的HO Type信息和/或Service Type信息。当UE发送Service Request消息以指示网络侧进行切换时,从网络侧支持的HO Type中选择本次切换所采用的HO Type,并将其携带于Service Request消息中。
继续参见图6,在602中,MME向E-UTRAN发送N2Request for HO(通过N2接口发送的切换请求)消息,该N2Request for HO消息中携带HO type信息。
在603中,E-UTRAN在向MME发送的HO Required消息中携带HO type信息。
在本发明实施例中,可以通过在Service Request消息、N2Request for HO消息和HO Required消息中采用一个字段进行表示,具体表示形式本发明并不加以限制,例如可以采用00表示RAT切换,采用01表示System切换,采用10表示Circuit Switch切换。对于该字段可以进行扩展,以支持后续出现的其他类型的切换方式。
在604中,MME依据HO Required消息中携带的HO type信息,确定触发的切换类型。
本步骤与实施例三中步骤502相同,具体参见实施例三中关于步骤502的描述,在此不做赘述。
以上是对本发明所提供的方法进行的详细描述,下面结合实施例对本发明提供的装置进行详细描述。

第一确定单元01负责确定切换类型信息。
这里主要包括两种情况:

另一种情况是接入网侧设备被动触发切换,UE向移动性管理设备发送携带切换类型信息的服务请求,移动性管理设备向接入网侧设备发送携带切换类型信息的切换请求。第一接收单元03接收来自移动性管理设备的切换请求后,第一确定单元01从切换请求中解析得到切换类型信息。
后一种情况下,UE需要获知网络侧支持的切换类型和业务类型。本发明实施例在UE的网络注册过程中,第一注册处理单元04将接入网侧设备支持的切换类型信息和/或业务类型信息发送给移动性管理设备,由移动性管理设备发送给UE。具体地,第一注册处理单元04可以将接入网侧设备支持的切换类型信息和/或业务类型信息携带在注册请求中

若从切换要求中未解析得到切换类型信息,但解析得到业务类型信息,且核心网支持该业务以及用户签约了该业务,则切换触发单元22触发RAT切换。
若从切换要求消息中未解析得到切换类型信息和业务类型信息,且移动性管理设备与切换要求消息携带的目标基站标识对应的目标基站连接,则切换触发单元22触发RAT切换。
若上述情况均不满足,例如从切换要求消息中未解析得到切换类型信息和业务类型信息,且移动性管理设备与切换要求消息携带的目标基站标识对应的目标基站未连接,则切换触发单元22触发系统切换。
上述切换类型可以包括:接入类型RAT切换、系统System切换或线路切换Circuit Switch。
图11为本发明实施例提供的设置于移动性管理设备的另一装置结构图,如图11所示,该装置可以包括:第三接收单元31和第三发送单元32,还可以包括第三注册处理单元33。其中各组成单元的主要功能如下:

第三注册处理单元33负责在UE的网络注册过程中,接收接入网侧设备发送的接入网侧设备支持的切换类型信息和/或业务类型信息;将网络侧支持的切换类型信息和/或业务类型信息发送给UE。具体地,第三注册处理单元33可以接收接入网侧设备发送的注册请求,注册请求携带接入网侧设备支持的切换类型信息和/或业务类型信息;向UE发送注册接受消息,注册接受消息携带网络侧支持的切换类型信息和/或业务类型信息。
需要说明的是,移动性管理设备可以同时包含上述图10和图11所示的装置结构。
