具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中,应理解,下述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本公开实施例的实施过程构成任何限定。
另外,本文中术语“系统”和“网络”在本文中常可互换使用。
在本公开所提供的实施例中,应理解,“与A相应的B”表示B与A相关联,根据A可以确定B。但还应理解,根据A确定B并不意味着仅仅根据A确定B,还可以根据A和/或其它信息确定B。
如图1所示,本公开实施例的一种移动性处理方法,应用于网络设备,包括:
步骤101,在用户设备从第一网络制式切换到第二网络制式后,确定所述用户设备是否支持第三网络制式。
这里,第一网络制式、第二网络制式和第三网络制式为不同的网络制式,用户设备UE可能都支持,也可能仅支持其中的部分制式。具体的,如第一网络制式为2G或者3G,第二网络制式为4G,第三网络制式为5G。本步骤中,在UE从2G或者3G切换到4G后,会确定该UE是否支持5G,以便针对UE的能力进行处理。其中,2G具体是指GERAN(GSM/EDGE Radio Access Network,GSM/EDGE无线接入网);3G具体是指UTRAN(UMTS Terrestrial Radio Access Network,UMTS陆地无线接入网络);4G具体是指E-UTRAN(Evolved Universal Terrestrial Radio Access Network,演进的UMTS陆地无线接入网络);5G具体是指5G系统5GS。
步骤102,在所述用户设备支持第三网络制式的情况下,触发所述用户设备重新附着。
本步骤中,在通过步骤101的判断,获知UE支持5G的情况下,触发UE重新附着,以保证后续4G到5G的连续性。
通过上述步骤101和102,本公开实施例的移动性处理方法,应用于网络设备,该网络设备可以是移动性管理实体MME,会在用户设备从第一网络制式切换到第二网络制式后,先确定该用户设备是否支持第三网络制式,之后,针对该用户设备支持第三网络制式的情况,触发该用户设备的重新附着,如此,用户设备可以通过第二网络制式和第三网络制式融合锚点,分配和同步第三网络制式参数,保证第二网络制式到第三网络制式的连续性。
例如,UE初始在2G接入,切换到4G后,MME会判断该UE的能力,即是否支持5G,在该UE支持5G的情况下,MME则触发UE在4G的重新附着,以使该UE选择4/5G融合锚点,分配和同步5G参数,实现后续该UE 切换5G的连续性。
可选地,所述确定所述用户设备是否支持第三网络制式,包括:
获取所述用户设备的网络能力信息;
根据所述网络能力信息,判断用户设备是否支持第三网络制式。
如此,MME能够通过用户设备的网络能力信息UE network capability对该UE的能力进行判断。
可选地,所述根据所述网络能力信息,判断用户设备是否支持第三网络制式,包括:
通过所述网络能力信息中的N1模式支持标志位,确定用户设备是否支持第三网络制式。
这里,可进一步由UE network capability中N1模式支持标志位(N1 mode support标志位)来确定该UE是否支持第三网络制式如5G。
可选地,所述触发所述用户设备重新附着,包括:
发送重新附着指示信息至所述用户设备。
如此,UE通过接收该重新附着指示信息,就会基于其进行重新附着。
应该知道的是,该重新附着指示信息可以是专用于指示UE重附着的信息,具有新的信令流程。当然,为例避免信令开销的消耗,该实施例中,会通过利用已有的信令流程实现该重新附着指示信息。可选地,一方面,所述发送重新附着指示信息至所述用户设备,包括:
发送跟踪区更新拒绝消息至所述用户设备,其中所述跟踪区更新拒绝消息的原因指示信息为所述重新附着指示信息。
其中,所述原因指示信息指示演进的分组系统EPS会话管理故障。
这里,MME回应跟踪区更新拒绝TAU Reject消息,来指示UE进行重新附着。其中TAU Reject携带原因指示信息cause作为该重新附着指示信息。进一步,TAU Reject携带cause为EPS会话管理故障ESM failure,来指示UE进行重新附着。
另一方面,可选地,所述发送重新附着指示信息至所述用户设备,包括:
发送跟踪区更新成功消息至所述用户设备,其中所述跟踪区更新成功消息的分组数据协议上下文状况指示信息为所述重新附着指示信息。
其中,所述分组数据协议上下文状况指示信息指示无公共数据网PDN连接迁移成功。
这里,MME回应TAU成功消息,来指示UE进行重新附着。且该TAU成功消息中的分组数据协议上下文状况指示PDP context status信息为重新附着指示信息。进一步,PDP context status指示无公共数据网PDN连接迁移成功,如PDP context status为空。
再一方面,所述发送重新附着指示信息至所述用户设备,包括:
在跟踪区更新成功的情况下,发送去附着消息至所述用户设备,其中所述去附着消息为所述重新附着指示信息。
这里,TAU成功后,MME触发MME去附着MME-initiated Detach流程,发送去附着消息来指示UE进行重新附着。将该去附着消息作为重新附着指示信息。
综上所示,本公开实施例的方法,在用户设备从第一网络制式切换到第二网络制式后,先确定该用户设备是否支持第三网络制式,之后,针对该用户设备支持第三网络制式的情况,触发该用户设备的重新附着,如此,用户设备可以通过第二网络制式和第三网络制式融合锚点,分配和同步第三网络制式参数,保证第二网络制式到第三网络制式的连续性。
如图2所示,本公开实施例的一种移动性处理方法,应用于用户设备,所述用户设备支持第一网络制式、第二网络制式和第三网络制式,所述方法包括:
步骤201,接收网络设备在所述用户设备从第一网络制式切换到第二网络制式后发送的重新附着指示信息。
步骤202,根据所述重新附着指示信息,进行重新附着。
这里,UE支持的第一网络制式、第二网络制式和第三网络制式为不同的网络制式,如第一网络制式为2G或者3G,第二网络制式为4G,第三网络制式为5G。本步骤中,将接收网络设备在UE从第一网络制式切换到第二网络制式后发送的重新附着指示信息,从而根据该重新附着指示信息进行重新附着,可通过第二网络制式和第三网络制式融合锚点,分配和同步第三网络制式参数,保证第二网络制式到第三网络制式的连续性。
如UE初始在2G接入,切换到4G后,MME会判断该UE的能力,即是否支持5G,在该UE支持5G的情况下,MME则触发UE在4G的重新附着,发送重新附着指示信息至UE,UE接收该重新附着指示信息后,进行4G的重新附着,以使该UE选择4/5G融合锚点,分配和同步5G参数,实现后续该UE切换5G的连续性。
可选地,所述接收网络设备在所述用户设备从第一网络制式切换到第二网络制式后发送的重新附着指示信息,包括:
接收所述网络设备发送的跟踪区更新拒绝消息,其中所述跟踪区更新拒绝消息的原因指示信息为所述重新附着指示信息;或者,
接收所述网络设备发送的跟踪区更新成功消息,其中所述跟踪区更新成功消息的分组数据协议上下文状况指示信息为所述重新附着指示信息;或者
接收在跟踪区更新成功的情况下,所述网络设备发送的去附着消息,其中所述去附着消息为所述重新附着指示信息。
这里,对应上一实施例中发送重新附着指示信息的实现方式,可进行对应的接收实现,在此不再赘述。
可选地,所述原因指示信息指示EPS会话管理故障。
可选地,所述分组数据协议上下文状况指示信息指示无PDN连接迁移成功。
如图3所示,本公开实施例的一种移动性处理方法,应用于网络设备,包括:
步骤301,在用户设备从第一网络制式切换到第二网络制式,且所述用户设备支持第三网络制式的情况下,将会话管理参数发送至所述用户设备,其中所述会话管理参数包括所述第三网络制式的服务质量QoS参数和/或所述第一网络制式的分组数据协议上下文参数。
这里,第一网络制式、第二网络制式和第三网络制式为不同的网络制式,UE可能都支持,也可能仅支持其中的部分制式。具体的,如第一网络制式为2G或者3G,第二网络制式为4G,第三网络制式为5G。本步骤中,应用本公开实施例方法的网络设备,如核心网(PGW-C+SMF(PDN网关控制面PGW-C和会话管理功能的融合设备SMF)或PCRF+PCF(策略与计费规则 功能PCRF和策略控制功能PCF的融合设备)),在UE从第一网络制式切换到第二网络制式,且支持第三网络制式的情况下,会将包括该第三网络制式的服务质量QoS参数和/或该第一网络制式的分组数据协议上下文参数的会话管理参数发送至UE,以使UE能够通过会话管理参数实现后续的网络制式切换,避免业务中断的发生。
例如,UE初始在2G或者3G接入,切换到4G后,且该UE支持5G的情况下,核心网会发送5G QoS parameters和/或2G或者3GPDP context parameters至该UE,以便UE能够通过5G QoS parameters和/或2G或者3GPDP context parameters实现后续的网络制式切换,避免业务中断的发生。
可选地,所述将会话管理参数发送至所述用户设备,包括:
通过承载修改流程发送所述第三网络制式的QoS参数和/或所述第一网络制式的分组数据协议上下文参数至所述用户设备;或者,
通过跟踪区更新响应消息发送所述第三网络制式的QoS参数和/或所述第一网络制式的分组数据协议上下文参数至所述用户设备。
如此,核心网可通过承载修改流程Bearer Modification Procedure发送5G QoS parameters和/或2G或者3G PDP context parameters。具体的,在Bearer Modification Procedure的第4步发送5G QoS parameters和/或2G或者3G PDP context parameters,如非接入层NAS消息修改EPS承载上下文请求Modify EPS bearer context request。或者,通过TAU响应消息发送5G QoS parameters和/或2G或者3G PDP context parameters。
可选地,在所述将会话管理参数发送至所述用户设备之前,还包括:
获取用户设备上报的协议数据单元会话标识。
如此,核心网在将该会话管理参数发送至UE之前,会获取到UE上报的协议数据单元会话标识PDU Session ID,即核心网是在接收到UE上报的PDU Session ID后才向UE进行会话管理参数的发送。
其中,所述获取用户设备上报的协议数据单元会话标识,包括:
通过承载资源修改请求流程或者跟踪区更新流程,获取所述协议数据单元会话标识。
这里,核心网是通过承载资源修改请求requested bearer resource  modification流程或者跟踪区更新TAU流程接收到UE发送的PDU Session ID。
另一方面,可选地,在所述将会话管理参数发送至所述用户设备之后,还包括:
获取用户设备上报的协议数据单元会话标识。
如此,核心网是将该会话管理参数发送至UE之后,才获取到UE上报的PDU Session ID的。
可选地,所述获取用户设备上报的协议数据单元会话标识,包括:
通过承载修改流程,获取所述协议数据单元会话标识。
这里,核心网是通过Bearer Modification Procedure来获取到PDU Session ID。
应该知道的是,该实施例中,PDU Session ID是UE在创建公共数据网络连接PDN connection时,UE分配的。UE和核心网都会基于会话管理参数在本地存储第一网络制式的分组数据协议上下文PDP context、第二网络制式的EPS上下文EPS Context和第三网络制式的协议数据单元会话上下文PDU Session Context。会话管理参数包括5G QoS parameters和/或2G或者3G PDP context parameters,UE和核心网会存储2G或者3G PDP context、EPS Context、5G PDU Session Context。其中,2G或者3G PDP context包括PDP context parameters,5G PDU Session Context包括QoS parameters。并且,具有5G能力的UE从4G切换到2G,PGW-C+SMF通过N7接口与PCRF+PCF互通。
在该实施例中,在所述将会话管理参数发送至所述用户设备之前,还包括:
若所述用户设备对应一PGW-C+SMF节点,且所述PGW-C+SMF节点为服务GPRS支持节点SGSN根据所述用户设备的网络能力信息或用户签约信息选择的,则确定所述用户设备支持第三网络制式。
这里,考虑到在2G或者3G激活PDP上下文时,核心网中SGSN会根据UE Network Capability信息或者用户签约信息选择一个PGW-C+SMF节点,因此,将基于该UE是否具有该PGW-C+SMF节点来确定UE是否支持5G。
下面,可结合具体场景说明本公开实施例的方法:
场景一:在UE从2G或者3G移动(切换)到4G后
