Description

切换处理方法、网络设备、终端设备及计算机存储介质 技术领域
本发明涉及信息处理技术领域,尤其涉及一种切换处理方法、网络设备、终端设备及计算机存储介质。
背景技术
在5G时代,下一代NG-无线接入网(RAN,Radio Access Network)可以包括gNB和eNB同时或分别接入5GC核心网的场景,对于NR基站来讲,向AMF(接入和移动管理功能)发送的切换请求Handover Require的消息是一样的,当发来的消息中的目标(Target)标识(ID)是eNB ID且该eNB既接入5GC又接入EPC时,AMF目前无法判断是否进行RAT切换(5GC不变,基站接入从NR变成eNB)还是System切换(5GC变成EPC)。
对于有N26接口的情况,若UE处于连接状态,则由NG-RAN根据测量门限值决定触发切换的时机;若UE处于空闲状态,则UE向目标核心网MME发送TAU Request,有MME负责向原核心网获得相关的上下文信息,并完成在目标核心网的位置更新流程。若没有N26接口,若UE可以识别网络侧发来的“支持无N26切换”指示,从而让合设的网元映射出4G的SM上下文,实现会话IP地址的一致性;UE若不识别网络侧发来的“支持无N26切换”指示,则直接做跟踪区域更新请求Tracking Area Update request。但是,上述几种切换处理均无法保证切换的及时性。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种切换处理方法,应用于第一网络设备,所述方法包括:
当位于第一系统网络或者第一核心网络中的第一网络设备、与终端设备之间存在连接时,所述第一网络设备为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接;
其中,所述候选连接用于当终端设备在满足预设条件时切换到目标系统网络或者目标核心网的时候使用。
通过上述方案,能够在终端设备未切换到目标系统网络或者目标核心网络的时候,预先为终端设备在目标系统网络或者目标核心网络建立候选连接。当终端与第一系统网络或者与第一核心网设备存在连接时,第一系统网络/核心网为终端建立目标系统网络/核心网设备的连接,用于终端在特定条件下切换到目标系统网络/核心网。
首先需要介绍的是关于是否为终端设备建立候选连接的判断条件:
基于以下至少一个条件,判断是否为所述终端设备建立与目标系统网 络、或者与目标核心网络之间的候选连接:
所述终端设备的链路质量、所述终端设备的属性信息、所述终端设备的业务信息、网络切片信息、所述终端设备的移动性信息。
具体来说,
条件1、所述终端设备的链路质量进行判断具体为,判断所述终端设备的链路质量是否满足预设门限值;当所述终端设备的链路质量满足预设门限值时,确定为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接。
也就是说,第一网络设备配置终端设备的门限值。当终端的链路质量满足配置的门限值时,终端上报测量报告到第一系统网络的接入网。第一系统的接入网向第一系统的核心网发送切换准备请求。第一系统的核心网为此终端准备目标系统网络或者目标核心网的链路。
条件2、当基于所述终端设备的属性信息,确定所述终端设备为能够建立候选连接的终端设备时,为所述终端设备建立与所述目标系统网络或者与目标核心网络之间的候选连接;
其中,所述终端设备的属性信息包括以下至少之一:终端的优先级信息,终端类型信息,终端等级信息。
就是说,当终端与第一系统网络或者第一核心网存在连接时,第一系统网络或者第一核心网基于终端信息为终端准备目标系统网络或者目标核心网的链路。网络可以通过签约信息获取终端信息或者终端上报终端信息。
可以理解的是,基于属性信息确定所述终端设备为能够建立候选连接的终端设备的具体处理中,可以为当终端的优先级信息为高于优先级门限值的时候,可以确定终端设备为能够建立候选连接的终端设备;或者,终端类型为处理低延迟业务的终端,可以确定终端为能够建立候选连接的终端设备;
另外,终端等级可以与终端优先级相对应,比如,终端等级存在1-10等级,其中,1-3等级可以对应优先级1,4-7对应优先级2,8-10可以对应优先级3,那么可以进一步基于等级所对应的优先级来确定终端设备是否为能够建立候选连接的终端设备。需要理解的是,前述终端等级仅为示例,实际上可以存在其他的设置方式,本实施例中不进行穷举。
条件3、当所述终端设备的业务信息表征所述终端设备的业务为符合第一条件的业务时,为所述终端设备建立与所述目标系统网络或者与目标核心网络之间的候选连接。其中,所述第一条件的业务为低时延业务。
业务信息中可以包含:业务的QoS信息等。例如当终端存在低时延要求的业务时,第一系统网络或者第一核心网为终端准备目标系统网络或者目标核心网的链路。
条件4、当所述网络切片信息符合第二条件时,确定为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接。
其中,所述第二条件表征所述网络切片的类型为低时延、和/或、高可靠性类型。
例如网络切片类型是低时延高可靠属性,则第一系统网络或者第一核心网为终端准备目标系统网络或者目标核心网的链路。
条件5、当基于所述终端设备的移动性信息确定所述终端设备为高移动性时,为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接。
第一系统网络/核心网获取终端的移动性信息,当终端是高移动性终端时,为终端准备目标系统网络或者目标核心网的链路。第一系统网络/核心网可以从终端或者接入网或者签约信息或者外部信息或者操作维护获取终端的移动性信息。
需要指出的是,上述5个条件仅为本实施例中举例说明的几个条件,实际上还可以存在更多的条件,只是不再进行穷举。并且,上述5个条件可以分别组合使用,具体的组合方式也不再穷举。
所述网络设备为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接,包括:通知目标系统网络、或者通知目标核心网络,为所述终端设备建立所述候选连接中的至少部分连接配置。
具体的,所述为所述终端设备建立所述候选连接中的至少部分连接配置,包括以下至少之一:
修改目标核心网络的内部PDU会话;
与目标核心网络的服务网关建立连接;
建立目标核心网络与接入网之间的连接。
也就是说,第一系统网络/核心网设备可以要求目标网络或者核心网设备为终端准备所有的连接配置或者部分的连接配置。具体的为执行前述三种处理中至少之一:
以图1中所示为例:修改目标核心网络的内部PDU会话,可以为(1)NG的接入网向核心网AMF发来切换请求,然后(2a)由AMF向核心网的内部的PGW-C SMF发送PDU会话建立请求,通过该请求修改核心网络内部的PDU会话;进而(2b)接收到反馈的会话建立请求的响应信息。
在图1的基础上,以图2所示为例:与目标核心网络的服务网关建立连接,具体为:(3)MME接收到AMF发来的重定位请求,然后(4-5)MME向服务网关(SGW)发送建立会话请求并接收到SGW反馈的建立会话响应;通过这些处理,使得目标核心网络与服务网关建立连接,并得到相应的连接配置;
进一步地,参见图3,建立目标核心网络与接入网之间的连接,也就是可以为MME与接入网中的E-UTRAN建立连接,通过(6、7)中的切换请求以及确认的处理建立连接及其得到对应的配置。
还需要说明的是,前述图1、2、3仅为示例,在前述说明的基础之上, 所述为所述终端设备建立所述候选连接中的至少部分连接配置,还可以包括:
目标核心网络中的网络设备,任意两个网络设备之间建立连接。
其中,目标核心网络中的网络设备可以包括有:AMF、MME、SGW、V-SMF、V-UPF、PGW-C-SMF以及PGW-C-UPF。这些设备虽然没有在前述图1、2、3中示出,但是在实际的核心网络中可以存在,只是不再进行图示说明。
所述第一网络设备为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接之后,所述方法还包括:当所述候选连接确认建立成功后,将候选连接的配置发送给终端。也就是说,当第一系统网络/核心网设备确认目标链路准备好之后,将目标网络连接配置发送给终端。
最后,本实施例中提供的方案,还可以进行连接定时处理,具体的参见图4,包括:
步骤401:当位于第一系统网络或者第一核心网络中的第一网络设备、与终端设备之间存在连接时,所述第一网络设备为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接;其中,所述候选连接用于当终端设备在满足预设条件时切换到目标系统网络或者目标核心网的时候使用;
步骤402:当所述候选连接建立成功时,开启定时器;
步骤403:当所述定时器的时长达到预设门限值、且所述终端设备未通过候选连接与目标系统网络或者目标核心网络建立连接时,释放所述候选连接。
也就是说,当一定时间内若终端设备未切换到目标网络,因此没有使用候选连接的情况下,网络侧不一定需要一直维持该候选连接的配置资源,可以在一定时长之后释放该候选连接。其中,定时器的时长所对应的预设门限值可以为根据实际情况进行设置,比如,可以设置为10分钟、或者可以设置为1小时,本实施例中不进行限定。
可见,通过采用上述方案,就能够为终端设备预先准备好目标网络中的候选连接,从而使得终端设备能够在移动到目标系统覆盖的范围内的时候,更加快速并且便捷的切换到目标系统网络或者目标核心网络中,提升切换处理效率,并且提升系统处理效率。

在图1的基础上,以图2所示为例:与目标核心网络的服务网关建立连接,具体为:(3)MME接收到AMF发来的重定位请求,然后(4-5)MME向服务网关(SGW)发送建立会话请求并接收到SGW反馈的建立会话响应;通过这些处理,使得目标核心网络与服务网关建立连接,并得到相应的连接配置;
进一步地,参见图3,建立目标核心网络与接入网之间的连接,也就是可以为MME与接入网中的E-UTRAN建立连接,通过(6、7)中的切换请求以及确认的处理建立连接及其得到对应的配置。
还需要说明的是,前述图1、2、3仅为示例,在前述说明的基础之上,所述为所述终端设备建立所述候选连接中的至少部分连接配置,还可以包括:
目标核心网络中的网络设备,任意两个网络设备之间建立连接。
其中,目标核心网络中的网络设备可以包括有:AMF、MME、SGW、V-SMF、V-UPF、PGW-C-SMF以及PGW-C-UPF。这些设备虽然没有在前述图1、2、3中示出,但是在实际的核心网络中可以存在,只是不再进行图示说明。
所述第一网络设备为所述终端设备建立与目标系统网络、或者与目标 核心网络之间的候选连接之后,所述方法还包括:当所述候选连接确认建立成功后,将候选连接的配置发送给终端。也就是说,当第一系统网络/核心网设备确认目标链路准备好之后,将目标网络连接配置发送给终端。
最后,本实施例中提供的方案,还可以进行连接定时处理,具体的:当所述候选连接建立成功时,开启定时器;
当所述定时器的时长达到预设门限值、且所述终端设备未通过候选连接与目标系统网络或者目标核心网络建立连接时,释放所述候选连接。
也就是说,当一定时间内若终端设备未切换到目标网络,因此没有使用候选连接的情况下,目标网络侧不一定需要一直维持该候选连接的配置资源,可以在一定时长之后释放该候选连接。其中,定时器的时长所对应的预设门限值可以为根据实际情况进行设置,比如,可以设置为10分钟、或者可以设置为1小时,本实施例中不进行限定。

首先需要介绍的是关于是否为终端设备建立候选连接的判断条件:
基于以下至少一个条件,判断是否为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接:
所述终端设备的链路质量、所述终端设备的属性信息、所述终端设备的业务信息、网络切片信息、所述终端设备的移动性信息。
具体来说,
条件1、所述终端设备的链路质量进行判断具体为,第一处理单元51,判断所述终端设备的链路质量是否满足预设门限值;当所述终端设备的链路质量满足预设门限值时,确定为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接。
也就是说,第一网络设备配置终端设备的门限值。当终端的链路质量满足配置的门限值时,终端上报测量报告到第一系统网络的接入网。第一系统的接入网向第一系统的核心网发送切换准备请求。第一系统的核心网为此终端准备目标系统网络或者目标核心网的链路。
条件2、第一处理单元51,当基于所述终端设备的属性信息,确定所述终端设备为能够建立候选连接的终端设备时,为所述终端设备建立与所述目标系统网络或者与目标核心网络之间的候选连接;
其中,所述终端设备的属性信息包括以下至少之一:终端的优先级信息,终端类型信息,终端等级信息。
就是说,当终端与第一系统网络或者第一核心网存在连接时,第一系统网络或者第一核心网基于终端信息为终端准备目标系统网络或者目标核心网的链路。网络可以通过签约信息获取终端信息或者终端上报终端信息。
可以理解的是,基于属性信息确定所述终端设备为能够建立候选连接的终端设备的具体处理中,可以为当终端的优先级信息为高于优先级门限值的时候,可以确定终端设备为能够建立候选连接的终端设备;或者,终端类型为处理低延迟业务的终端,可以确定终端为能够建立候选连接的终端设备;
另外,终端等级可以与终端优先级相对应,比如,终端等级存在1-10等级,其中,1-3等级可以对应优先级1,4-7对应优先级2,8-10可以对应优先级3,那么可以进一步基于等级所对应的优先级来确定终端设备是否为能够建立候选连接的终端设备。需要理解的是,前述终端等级仅为示例,实际上可以存在其他的设置方式,本实施例中不进行穷举。
条件3、第一处理单元51,当所述终端设备的业务信息表征所述终端设备的业务为符合第一条件的业务时,为所述终端设备建立与所述目标系统网络或者与目标核心网络之间的候选连接。其中,所述第一条件的业务为低时延业务。
业务信息中可以包含:业务的QoS信息等。例如当终端存在低时延要求的业务时,第一系统网络或者第一核心网为终端准备目标系统网络或者目标核心网的链路。
条件4、第一处理单元51,当所述网络切片信息符合第二条件时,确定为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接。
其中,所述第二条件表征所述网络切片的类型为低时延、和/或、高可靠性类型。
例如网络切片类型是低时延高可靠属性,则第一系统网络或者第一核心网为终端准备目标系统网络或者目标核心网的链路。
条件5、第一处理单元51,当基于所述终端设备的移动性信息确定所述终端设备为高移动性时,为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接。
第一系统网络/核心网获取终端的移动性信息,当终端是高移动性终端时,为终端准备目标系统网络或者目标核心网的链路。第一系统网络/核心网可以从终端或者接入网或者签约信息或者外部信息或者操作维护获取终端的移动性信息。
需要指出的是,上述5个条件仅为本实施例中举例说明的几个条件,实际上还可以存在更多的条件,只是不再进行穷举。并且,上述5个条件可以分别组合使用,具体的组合方式也不再穷举。
所述第一网络设备还包括:
第一通信单元52,通知目标系统网络、或者通知目标核心网络,为所述终端设备建立所述候选连接中的至少部分连接配置。
具体的,所述为所述终端设备建立所述候选连接中的至少部分连接配 置,包括以下至少之一:
修改目标核心网络的内部PDU会话;
与目标核心网络的服务网关建立连接;
建立目标核心网络与接入网之间的连接。
也就是说,第一系统网络/核心网设备可以要求目标网络或者核心网设备为终端准备所有的连接配置或者部分的连接配置。具体的为执行前述三种处理中至少之一:
以图1中所示为例:修改目标核心网络的内部PDU会话,可以为(1)NG的接入网向核心网AMF发来切换请求,然后(2a)由AMF向核心网的内部的PGW-C SMF发送PDU会话建立请求,通过该请求修改核心网络内部的PDU会话;进而(2b)接收到反馈的会话建立请求的响应信息。
在图1的基础上,以图2所示为例:与目标核心网络的服务网关建立连接,具体为:(3)MME接收到AMF发来的重定位请求,然后(4-5)MME向服务网关(SGW)发送建立会话请求并接收到SGW反馈的建立会话响应;通过这些处理,使得目标核心网络与服务网关建立连接,并得到相应的连接配置;
进一步地,参见图3,建立目标核心网络与接入网之间的连接,也就是可以为MME与接入网中的E-UTRAN建立连接,通过(6、7)中的切换请求以及确认的处理建立连接及其得到对应的配置。
还需要说明的是,前述图1、2、3仅为示例,在前述说明的基础之上,所述为所述终端设备建立所述候选连接中的至少部分连接配置,还可以包括:
目标核心网络中的网络设备,任意两个网络设备之间建立连接。
其中,目标核心网络中的网络设备可以包括有:AMF、MME、SGW、V-SMF、V-UPF、PGW-C-SMF以及PGW-C-UPF。这些设备虽然没有在前述图1、2、3中示出,但是在实际的核心网络中可以存在,只是不再进行图示说明。
所述第一网络设备为所述终端设备建立与目标系统网络、或者与目标核心网络之间的候选连接之后,所述方法还包括:,所述第一网络设备还包括:
第一通信单元52,当所述候选连接确认建立成功后,将候选连接的配置发送给终端。也就是说,当第一系统网络/核心网设备确认目标链路准备好之后,将目标网络连接配置发送给终端。
所述第一处理单元,当所述候选连接建立成功时,开启定时器;当所述定时器的时长达到预设门限值、且所述终端设备未通过候选连接与目标系统网络或者目标核心网络建立连接时,释放所述候选连接。
也就是说,当一定时间内若终端设备未切换到目标网络,因此没有使用候选连接的情况下,网络侧不一定需要一直维持该候选连接的配置资源, 可以在一定时长之后释放该候选连接。其中,定时器的时长所对应的预设门限值可以为根据实际情况进行设置,比如,可以设置为10分钟、或者可以设置为1小时,本实施例中不进行限定。
可见,通过采用上述方案,就能够为终端设备预先准备好目标网络中的候选连接,从而使得终端设备能够在移动到目标系统覆盖的范围内的时候,更加快速并且便捷的切换到目标系统网络或者目标核心网络中,提升切换处理效率,并且提升系统处理效率。
实施例五、

也就是说,第一系统网络/核心网设备可以要求目标网络或者核心网设备为终端准备所有的连接配置或者部分的连接配置。具体的为执行前述三种处理中至少之一:
以图1中所示为例:修改目标核心网络的内部PDU会话,可以为(1)NG的接入网向核心网AMF发来切换请求,然后(2a)由AMF向核心网的内部的PGW-C SMF发送PDU会话建立请求,通过该请求修改核心网络内部的PDU会话;进而(2b)接收到反馈的会话建立请求的响应信息。
在图1的基础上,以图2所示为例:与目标核心网络的服务网关建立 连接,具体为:(3)MME接收到AMF发来的重定位请求,然后(4-5)MME向服务网关(SGW)发送建立会话请求并接收到SGW反馈的建立会话响应;通过这些处理,使得目标核心网络与服务网关建立连接,并得到相应的连接配置;
进一步地,参见图3,建立目标核心网络与接入网之间的连接,也就是可以为MME与接入网中的E-UTRAN建立连接,通过(6、7)中的切换请求以及确认的处理建立连接及其得到对应的配置。

所述第二处理单元,当所述候选连接确认建立成功后,将候选连接的配置发送给终端。也就是说,当第一系统网络/核心网设备确认目标链路准备好之后,将目标网络连接配置发送给终端。
最后,本实施例中提供的方案,还可以进行连接定时处理,具体的:所述第二处理单元,当所述候选连接建立成功时,开启定时器;当所述定时器的时长达到预设门限值、且所述终端设备未通过候选连接与目标系统网络或者目标核心网络建立连接时,控制第二通信单元释放所述候选连接。
也就是说,当一定时间内若终端设备未切换到目标网络,因此没有使用候选连接的情况下,目标网络侧不一定需要一直维持该候选连接的配置资源,可以在一定时长之后释放该候选连接。其中,定时器的时长所对应的预设门限值可以为根据实际情况进行设置,比如,可以设置为10分钟、或者可以设置为1小时,本实施例中不进行限定。
