Description

管理用户数据的方法和装置
本申请要求于2018年06月26日提交中国国家知识产权局、申请号为201810671993.3、申请名称为“管理用户数据的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及管理用户数据的的方法和装置。
背景技术
在5G中引入了UE策略的下发防止UE策略重复下发的机制，该机制中包括策略控制功能(policy control function，PCF)装置将成功下发给UE的UE策略的策略分组标识(Policy Section Identifier，PSI)及对应的策略内容存入UDR。UDR中存储已经下发的PSI及对应的策略信息，用于防止UE策略的重复下发，UDR中存储的UE策略的PSI及对应的策略内容即使UE关机不会被删除。此外，AMF会在UE去注册之后删除签约信息和MM上下文，这种情况下，AMF会触发“Purge of subscriber data in AMF”流程，该流程用于删除签约信息和MM上下文。
在漫游场景中，V-PCF会将访问公共陆地移动网络(Visited Public Land Mobile Network，VPLMN)已经下发的UE策略的PSI和对应的策略内容存储在V-UDR，然而UE会从一个VPLMN移动到另一个VPLMN，或者从VPLMN移动回本地公共陆地移动网络(Home Public Land Mobile Network，HPLMN)，此时，V-UDR中存储的该UE的PSI及对应的策略内容已经没有价值。但是V-UDR中的PSI及其对应的策略信息内容因没有相应的删除机制，会一直保留。V-UDR的存储空间有限，在漫游用户数量较多且更新较快的情况下，会大量浪费V-UDR的存储资源。
发明内容
本申请实施例提供了一种数据管理的方法和装置，有助于节省存储资源。
第一方面，提供了一种一种管理数据的方法，该方法包括：

所述第一通信装置接收所述第二通信装置发送的所述策略信息。
可见，该技术方案中，通过第一和第二通信装置向第三通信装置获取策略信息，第三通信装置的策略信息并非按照每个UE为粒度分类进行存储，不会一直存储冗余信息，提高了获取效率，节省了存储空间。
第二方面，管理数据的方法，该方法包括：
第二通信装置接收第一通信装置发送的第一请求信息，所述第一请求信息包含用户设备UE的用户永久性标识SUPI信息；
所述第二通信装置向第三通信装置发送第二请求信息，所述第二请求信息包含当前为UE服务的公共陆地移动网络PLMN的PLMN ID信息，所述UE的当前位置区域信息和UE能力信息中的至少一种；所述第二请求信息用于向第三通信装置请求存储在所述第三通信装置中的所述UE的策略信息，其中所述策略信息是以位置区域为分类存储在所述第三通信装置；

需要说明的是，图1中的各装置，如终端、RAN设备、AMF装置、SMF装置、PCF装置、UDM装置以及UDR装置等仅是一个名字，名字对设备本身不构成限定。在5G网络以及未来其它的网络中，这些装置还可以是其他的名字，本申请实施例对此不作具体限定。例如，AMF装置还有可能被替换为AMF或者AMF实体等，SMF装置还有可能被替换为SMF或者SMF实体等，在此进行统一说明，以下不再赘述。
图2为5G策略控制架构示意图，策略控制相关的网络架构中有网络数据分析功能(network data analytics function，NWDAF)装置，NWDAF能够对大数据进行分析，并能够向网络架构中的策略控制装置(policy control function，PCF)发送基于分析得到的分析信息，PCF能够基于NWDAF发送的分析信息生成策略，并能够将生成的策略发送给策略控制执行装置，例如，网络架构中的接入或移动性管理功能(Access and Mobility Management Function,AMF),或者会话管理功能(Session Management Function，SMF)等，策略控制执行装置可以控制该策略得以执行。
图3为非漫游场景下基于服务化接口的5G网络架构的示意图，如图3所示，基于服务化接口场景下，5G系统的核心网还包括NEF和NRF装置。基于服务化接口的场景下，5G核心网中的部分装置通过总线方式连接，如图3所示，AUSF装置、AMF装置、SMF装置、AF装置、UDM、PCF装置、网络存储功能(Network Repository Function，NRF)装置、网络开放功能(Network Exposure Function，NEF)装置和NSSF装置通过总线互连，所述装置在通过总线互连时，采用服务化接口，例如，AUSF装置通过Nausf接口连接到总线上，AMF装置采用Namf接口连接到总线上，SMF装置通过Nsmf接口连接到总线上，AF装置采用NAF装置接口连接到总线上，UDM采用Nudm接口连接到总线上，PCF装置通过NPCF装置接口连接到总线上，NRF通过Nnrf接口连接到总线上，NEF通过Nnef接口连接到总线上，NSSF通过Nnssf接口连接到总线上。
根据根据移动终端的漫游业务接入策略，可以分为两种漫游方式：Home routed(家乡路由)漫游接入、Local breakout(本地疏导)漫游接入。Home routed漫游接入，指漫游用户通过归属网络的网关(或者具有网关相同功能的其他)接入获取归属网络提供的业务。Local breakout漫游接入，指漫游用户通过拜访网络的网关接入获取相应的业务，业务的提供者可以是归属网络，也可以是拜访网络。
图4为Local breakout漫游场景下基于服务化接口的5G策略控制架构的示意图，如图4所示，访问公共陆地移动网络(Visited Public Land Mobile Network，VPLMN)和本地公共陆地移动网络(Home Public Land Mobile Network，HPLMN)。控制接入和移动性策略控制的PCF有两个，分别位于VPLMN和HPLMN，即V-PCF和H-PCF。
图5为Home routed漫游场景下基于服务化接口的5G策略控制架构的示意图，如图5所示，控制接入和移动性策略控制的PCF有两个，分别位于VPLMN和HPLMN，即V-PCF和H-PCF。VPLMN。
当本申请的方法应用在LTE系统时，核心网为演进分组核心网EPC，其中包括：移 动性管理(mobility management entity，MME)、分组数据网关(packet data network gateway，P-GW)、业务网关(Serving Gateway，S-GW)、归属网络服务器(Home Subscriber Server，HSS)等。其中，HSS用于存储用户签约信息，包括用户业务信息、鉴权信息、位置管理信息等；MME负责终端接入控制、移动性管理、会话管理、装置选择(如S-GW/P-GW选择)等功能；SGW是eNB之间切换的移动性锚点，负责用户面数据的路由转发等功能；PGW则负责IP地址分配、分组数据过滤、速率控制和计费规则的执行以及合法监听等功能。
本申请中提到的UE可以是：手机、电脑，还可以为蜂窝电话、无绳电话、会话发起协议(session initiation protocol，SIP)电话、智能电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(set top box，STB)、车载设备、可穿戴设备、智能家居设备、用于在无线系统上进行通信的其它设备等。
图6为策略信息的存储架构示意图，在漫游场景下，V-PCF会将VPLMN已经下发的UE Policy(策略)信息的PSI和对应的策略内容存储在V-UDR，而且不会删除。此外，PCF在UDR中存储已经下发的PSI及对应的策略信息，用于防止UE策略的重复下发，UDR中的内容即使UE关机也不会被删除。UE会从一个VPLMN移动到另一个VPLMN，或者从vPLMN移动回HPLMN，此时，V-UDR中存储的该UE的PSI及对应的策略内容已经没有价值，并占用了存储资源。
图7为本申请实施例提供的一种数据管理方法的流程图。在图7所示的实施例中，第一通信装置向第二通信装置发送第一指示信息，所属第一指示信息用于指示所述第二通信装置触发删除存储在第三通信装置的UE策略信息；该UE策略信息，为漫游接入到第二通信装置的UE的UE策略信息。第二通信装置接收该第一指示信息，触发删除存储在第三通信装置的UE策略信息。
在图7所示的实施例中，第一通信装置向第二通信装置发送第一指示消息，通过第一指示消息，指示第二通信装置触发删除流程，第二通信装置向第三通信装置发起该删除流程，使得第三通信装置中的UE策略信息被删除，从而节省了第三通信装置的存储资源。
图8为本申请实施例提供的一种数据管理方法的流程示意图，本实施例是以应用于5G架构为例。第一通信装置为AMF，为UE接入当前AMF(新AMF)之前所接入的AMF，即旧AMF；第二通信装置为PCF，为VPLMN的访问PCF(visited PCF，V-PCF)；第三通信装置为UDR,为VPLMN的访问UDR(visited UDR，V-UDR)。
801，旧AMF确定删除V-UDR上的UE策略信息。
在一种可选的实施方式中，旧AMF接收新AMF发送的PLMN标识(identity，ID)信息或UDR组ID信息，该PLMN ID信息或UDR组ID信息可包含在新AMF向旧AMF发送请求UE上下文消息中，如在UE注册流程中发送。也可作包含在其它消息中发送，或作为独立的消息发送给旧AMF。新AMF发送的PLMN ID信息，为当前为UE服务的PLMN的PLMN ID信息，即新AMF所在的公共陆地移动网络(Public Land Mobile  Network，PLMN)的PLMN ID信息；UDR组ID信息为当前可以为UE服务的一个或多个UDR的所组成的UDR组的标识信息。
当旧AMF所接收到的为旧AMF发送PLMN ID信息，旧AMF根据该PLMN ID信息确定是否需要删除UE策略信息，即确定是否向V-PCF发送第一指示信息。当所接收到的PLMN ID和旧AMF本身所存储的PLMN ID信息不相同时，旧AMF确定需要删除UE策略信息，即旧AMF确定要向V-PCF发送第一指示信息。
漫游域运营商会用不同的UDR存储不同UE的信息，且有可能会根据地域等信息改变为同一用户服务的UDR。UDR组为包含了一个或多个可能为这一用户服务的UDR。如果不同AMF所对应的UDR组ID信息相同，则为对应位置UE服务的V-UDR也相同。当旧AMF所接收到的为新AMF发送UDR组ID信息，旧AMF根据该UDR组ID信息确定是否需要删除UE策略信息，即确定是否向V-PCF发送第一指示信息。当所接收到的UDR组ID信息和旧AMF本身所存储的UDR组ID信息不相同时，旧AMF确定需要删除UE策略信息，即旧AMF确定需要向V-PCF发送第一指示信息。
新AMF也可以向旧AMF发送PLMN ID信息和UDR组ID信息，旧PCF可根据其中至少一个来确定是否向V-PCF发送第一指示信息。
在另一种可选的实施方式中，当前为所述UE服务的PLMN的PLMN ID信息配置于旧AMF中。在旧AMF上配置与该旧AMF有接口连接的其它AMF所对应的PLMN ID信息，表1举例说明了一种配置方式，AMF1可以为该旧AMF，AMF2和AMF3为其它AMF，每个AMF都对应有PLMN ID信息，如AMF1对应的PLMN ID信息为PLMN1，AMF2对应的PLMN ID信息为PLMN2，AMF3对应的PLMN ID信息为PLMN3，该表1仅以3个AMF举例，另外表1也可不包含该旧AMF本身。当表1中的新AMF的PLMN ID信息与旧AMF的PLMN ID信息不同，则旧AMF向V-PCF发送第一指示信息。
AMF ID PLMN ID
AMF1(可以是旧AMF本身) PLMN1
AMF2 PLMN1
AMF3 PLMN2
表1
在另一种可选的实施方式中，旧AMF决定删除UE的签约信息和移动性管理(Mobility Management，MM)上下文时，或在删除UE的签约信息和MM上下文的过程中，或在删除UE的签约信息和MM上下文后，旧AMF向V-PCF发送第一指示信息。其中旧AMF会在UE去注册之后删除UE的签约信息和MM上下文，旧AMF通过触发“AMF用户数据清除流程(Purge of subscriber data in AMF)”流程，来删除UE的签约信息和MM上下文。该“Purge of subscriber data in AMF”流程具体为：旧AMF向UDM发送Nudm_SDM_Unsubsrcibe request(取消订阅请求)信息，UDM向旧AMF发送Nudm_SDM_Unsubsrcibe reponse(取消订阅相应)信息；旧AMF向UDM发送Nudm_UECM_Deregistration request(取消登记请求)信息，UDM向旧AMF发送Nudm_ UECM_Deregistration reponse(取消登记响应)信息。
802，旧AMF向V-PCF发送第一指示消息，该第一指示消息用于指示V-PCF触发删除存储在V-UDR上的UE策略信息。
在一种可选的实施方式中，旧AMF向V-PCF发起AM策略关联终止时，向V-PCF发送Npcf_AMPolicyControl_Delete(AM策略控制删除)信息，该Npcf_AMPolicyControl_Delete信息种可包含第一指示信息。第一指示信息可为V-UDR删除指示，例如指示PLMN改变，或指示UDR组改变，来指示V-PCF触发删除存储在V-UDR上的UE策略信息，可以用策略控制请求触发器(policy control request trigger)作为第一指示信息，该策略控制请求触发器可为常规设置，或由V-PCF决定是否设置。策略控制请求触发器具体如表2所示：
Figure PCTCN2019092961-appb-000001
表2
该第一指示信息也可包含在其它由旧AMF发送给V-PCF的消息中，或作为一条单独的消息发送。此外，第一指示信息中包括UE的ID，例如用户永久性标识(subscription permanent identifier，SUPI)信息。
803，当V-PCF收到第一指示消息，V-PCF触发删除存储在V-UDR上的UE策略信息。
在一种可选的实施方式中，V-PCF通过向V-UDR发送第二指示信息来触发V-UDR删除UE的策略信息，其中第二指示信息用于指示V-UDR删除UE的策略信息。可选的，第二指示信息还包括UE的ID，例如SUPI信息。
V-PCF可以通过Nudr_DM_Delete(删除)服务来触发存储在V-UDR上的UE策略信息被删除。V-PCF向V-UDR发送Nudr_DM_Delete信息，该Nudr_DM_Delete消息即为第二指示信息，该Nudr_DM_Delete信息中的Data Set(数据组)为Policy Data，Data Subset(数据子集)为“Policy Set Entry(策略组记录)”，V-UDR接收到该Nudr_DM_Delete信息后，删除该UE的SUPI对应的策略信息，即删除其所存储的策略分组标识(Policy Section Identifier，PSI)及其对应的UE策略信息。V-UDR完成删除后，可向V-PCF发送删除第一反馈信息，用于通知V-PCF已完成删除。V-PCF也可向旧AMF发送第二反馈信息，用于通知旧AMF已完成删除，该第二反馈信息可以为Npcf_AMPolicyControl_Delete response(AM策略控制删除相应)信息，或包含在Npcf_AMPolicyControl_Delete response信息中。
本申请还提供了另一实施例。在本实施例中，第三通信装置被配置为存储UE的策略 信息。该第三通信装置可以被配置为，以UE所在的位置区域为基础，即以位置区域为粒度，进行分类来存储策略信息。其中配置可以为网管通过将策略信息输入或其它方式提供给第三通信装置，使得该策略信息存储在第三通信装置中。位置区域为分类标准来存储，可以通过位置区域作为关键词来实现，通过检索以区域位置作为关键词的策略信息，对位到所需的策略信息。这种形式的存储形式，极大的节省了存储资源，并且能够高效的定位到所需的信息。
第三通信装置可以为UDR，并可作为V-UDR。如果V-UDR每个UE为基础分类来存储策略信息，因为漫游用户会离开VPLMN，则V-UDR需要存储大量无用的策略信息。在本实施例中，V-UDR仅存储所有漫游用户的ANDSP能力信息，以PLMN ID或位置区域信息来分类，V-PCF不需要为每个UE区存储PSI信息及其对应的内容。PCF根据UE所来自的PLMN和UE当前位置，来确定提供给该UE的策略信息，并可从V-UDR获取该策略信息提供给UE。
表3为位置粒度存储UE策略信息的一种存储形式举例，PLMN ID，Location Area(位置区域)，UE capability(UE能力)和PSI Content(PSI内容)几种信息直接被整理归类，按照不同的Location Area分类存储UE策略信息。如可对应跟踪区1，2，3存储位于该区域的UE的策略信息，可对应小区101存储位于该区域的UE的策略信息。不同的策略信息可用PSI进行标识，如PSI 1，PSI 2等。如表格2中所示，跟踪区1，2，3对应策略信息PSI 1，2，3，即PSI 1，PSI 2和PSI 3所指示的策略信息为位于跟踪区1，2，3的UE的策略信息。

表4
如图9所示，AMF为第一通信装置，V-PCF为第二通信装置，在步骤901中AMF向V-PCF发送第一请求信息，所述请求信息至少包括UE的SUPI信息。所述第一请求信息用于指示第二通信装置向第三通信装置获取存储在所述第三通信装置中的所述UE的策略信息。该第一请求信息可以是策略建立请求信息，如可以为Npcf_AMPolicyControl_Create(AM策略控制建立)信息，还可以为策略更新请求信息，如Npcf_AMPolicyControl_update(AM策略控制更新)信息。
在步骤902中，V-PCF接收到该请求信息后，向第三通信装置UDR发送第二请求信息，该第二请求信息可包括当前为UE服务的PLMN ID，即PLMN ID，位置区域信息，能力信息中的至少一种。其中HPLMN ID指UE归属域的PLMN的PLMN ID，Location Area指UE当前的位置信息，能力信息指示UE是否需要ANDSP。V-UDR接收到该第二请求信息后，如表3所示和表4所示，根据其中包含的HPLMN ID，位置区域信息，能力信息，定位到对应的PSI内容，即PSI所对应的策略信息，将对应的PSI策略信息发送给V-PCF。可选的，还可以将PSI列表也发送给V-PCF。
V-PCF接收到V-UDR发送的策略信息后，发送给AMF。
在初始注册时，UE提供标识当前存储在UE中的策略信息的PSI的列表，如果在UE中没有存储策略信息，或者USIM改变，例如更换SIM卡或UE非正常掉电或新插入的SIM卡第一次连接入网，则UE不提供任何PSI。如果UE不支持非3GPP接入，则UE应指示它不支持ANDSP。在这种情况下，PCF不应发送ANDSP给UE。AMF在Npcf_AMPolicyControl_Create过程中向PCF提供UE接入选择和PDU会话相关策略信息。例如当UE在没有改变USIM的情况下开机，UE可以利用所存储的PSI列表来触发初始注册以请求同步。hPCF接收AMF通过Npcf_AMPolicyControl_Create流程提供的第一PSI列表，在漫游场景中，V-PCF通过如图8所示的方式，获取存储在V-UDR中的第二PSI列表及第二PSI列表所对应的策略信息内容，其中存储在V-UDR中的第二PSI列表及其所对应的策略信息内容，是以用户的PLMN ID和用户设备的位置区域为分类标准进行存储的，其存储形式可参照本申请表3和表4及其对应的实施例。
