- EASDF creates a DNS context for this PDU session to store the received UE IP address, DNS message handling rule and other information. EASDF replies to SMF on DNS The following creates a response (Neasdf_DNSContext_Create Response).
- SMF includes the IP address of EASDF as the DNS server address in the PDU session establishment reception message, that is, the PDU Session Establishment Accept message, and sends it to the UE.
- the UE sends a DNS query message (DNS Query message) to EASDF.
- DNS query message DNS Query message
- Neasdf_DNSContext_Notify Request is reported only when the DNS Query matches the rules in the DNS message handling rule (i.e. DNS message detection template). In this example, this step is required by default, but it is not limited to this.
- SMF determines that the requested FQDN is associated with the same dynamic group (for example, the requested FQDN is included in a specific FQDN set) based on the received FQDN and the FQDN information received in PDU sessions established by other UEs, Or based on the UE location (for example, the UE moves), when it is determined that the UE is associated with a dynamic group, it is necessary to provide the same EAS information (such as EAS IP address), access the same DNAI and/or access the same L -DN, so you need to update the DNS message handling rule, for example, modify the Local DNS IP address in the Forwarding Action, or add the same EDNS Client Subnet option information.
- SMF sends the new DNS message handling rule to EASDF by calling the DNS context update request (Neasdf_DNSContext_Update Request).
- the dynamic UE group is re-determined based on the FQDN, and the DNS message handling rule is updated accordingly for sending.
- the DNS message handling rule is updated accordingly for sending.

- the dynamic UE group is re-determined based on the FQDN, and the DNS message handling rule is updated accordingly for sending.
- EASDF processes the received DNS Query message according to the DNS message handling rule. For the sent DNS Query message to satisfy the DNS message handling rule, these DNS Query messages need to be sent to the same Local DNS server or the instruction information (corresponding to the above target instruction information) is added through the EDNS Client Subnet option. For example, according to the Forwarding Action, if the target FQDN in the DNS Query information matches the FQDN set associated with a specific application, execute 1) send the DNS Query information to the Local DNS server indicated by the SMF, or 2) add it through the EDNS Client Subnet option Indication information indicating a specific IP range.
- EASDF receives the EAS information (such as EAS IP address) determined by the DNS system (DNS server) and includes it in the DNS Response sent to the UE.
- EAS information such as EAS IP address
- EASDF calls Neasdf_DNSContext_Notify request to send the DNS message reporting (DNS message reporting) to SMF.
- DNS message report can contain multiple EAS information (such as EAS IP address), and may include FQDN and EDNS Client Subnet option.
- SMF saves EAS information, each PDU session information, and UE information belonging to the same dynamic group. SMF replies Neasdf_DNSContext_Notify Response to EASDF.
- SMF determines the DNAI and N6 routing information, and optionally performs the selection and insertion of UL CL/BP (i.e. UL CL or BP) and Local PSA UPF (thereby ensuring that PDU sessions belonging to the same dynamic group select the same DNAI , or DNAI that can access the same EAS set or L-DN).
- UL CL/BP i.e. UL CL or BP
- Local PSA UPF thereby ensuring that PDU sessions belonging to the same dynamic group select the same DNAI , or DNAI that can access the same EAS set or L-DN.
- at least one of the uplink data classifier UL CL or branch point, and the PDU session anchor point UPF is selected and/or inserted.
- SMF will determine the DNAI based on the EAS information belonging to the same dynamic group and each PDU session information (corresponding to the above-mentioned first information of at least one terminal in the first dynamic terminal group, configured for the UPF device or EASDF device Processing rules) to ensure that the same DNAI is selected for PDU sessions belonging to the same dynamic group, or the DNAI of the same EAS set or L-DN can be accessed.

- EAS information can be determined based on DNS message handling rules.
- EAS information such as EAS IP address
- EASDF sends the DNS Response containing the EAS IP address to the UE, which will not be described again here.
- This example describes how SMF configures the same EAS information (such as one or more EAS IP addresses) to EASDF to discover EAS information (such as EAS IP addresses); specifically, there are similarities between this example and Example 1. Based on Example 1, the main differences are as follows:
- Step 9 SMF determines that the requested FQDN is associated with the same dynamic group (for example, the requested FQDN is included in a specific FQDN set) based on the received FQDN and the FQDN information received in the PDU session established by other UEs. , determine that the same EAS information needs to be provided (for example, one or more EAS IP addresses), then update the DNS message handling rule to include the EAS information in the DNS message handling rule.
- the same EAS information needs to be provided (for example, one or more EAS IP addresses)
- the SMF indicates that if the FQDN sent by the UE satisfies the DNS message handling rule, the EAS information (including one or more EAS IP addresses, for example, multiple EAS IP addresses correspond to the same DNAI, or are deployed on the same L- DN) is sent to the corresponding UE through EASDF. For example, add a new action in Forwarding Action: If the target FQDN in the DNS Query information matches the FQDN set associated with a specific application, then send specific EAS information (such as EAS IP range, including one or more EAS IP addresses) to the UE through EASDF .
- EAS information including one or more EAS IP addresses, for example, multiple EAS IP addresses correspond to the same DNAI, or are deployed on the same L- DN
- SMF may provide valid time information of EAS information (such as EAS IP range) (corresponding to the valid time information of the above processing rules themselves).
- the valid time information may be an indicator to indicate that EASDF can respond to the request within the valid time.
- the UE of the corresponding FQDN directly returns EAS information (such as EAS IP), and when the validity time exceeds, EASDF will send DNS Query to the DNS server to regain the parsed EAS information (such as EAS IP) and return it to the UE.
- SMF can send the new DNS message handling rule to EASDF by calling Neasdf_DNSContext_Update Request.
- Step 11 EASDF processes the received DNS Query message according to the DNS message handling rule. For example, according to the Forwarding Action: If the target FQDN in the DNS Query information matches the set of FQDNs associated with a specific application, then include specific EAS information (containing one or more EAS IP addresses) in the DNS Response.
- EASDF can determine whether to directly return EAS information (such as one or more EAS IP addresses) based on the valid time information, or whether to send a DNS Query to the DNS server to obtain it. If SMF does not provide valid time information, EASDF can also determine the valid time based on the local configuration policy (corresponding to the local policy configuration of EASDF above); but it is not limited to this.
- EASDF can also determine the valid time based on the local configuration policy (corresponding to the local policy configuration of EASDF above); but it is not limited to this.
- Steps 12-14 in Example 1 are not executed in this example.
- Step 16 EASDF includes the determined EAS information (such as EAS IP) in the DNS Response and sends it to the UE.
- EAS information such as EAS IP
- step 15 is the same as Example 1.
- EAS information such as EAS IP address
- Local DNS Server As shown in Figure 10, it includes the following operations:
- the UE sends a PDU session establishment request to the SMF.

- the DNAI for example, ensure that UEs belonging to the same dynamic group Access the same EAS, DNAI and/or L-DN
- the SMF determines to insert the UL CL/BP.
- SMF configures rules to UL CL/BP, including: SMF configures traffic routing rules to UL CL or BP, and provides the same DNS in the traffic routing rules server address (configured to UL CL) or the same IP prefix (configured to BP).
- SMF configures traffic routing rules on the upstream data classifier UL CL or the branch point BP.
- IP prefix represents the IP address prefix.
- the SMF feeds back the PDU session establishment request response to the UE.
- SMF includes the same DNS server address in the PDU session establishment reception information, and sends it to the UE corresponding to the PDU Session Establishment Accept message; of course, it can also be sent through the PDU Session Modification process.
- Sent to the UE for example, including the Local DNS server address in the Protocol Configuration Options (PCO); but it is not limited to this.
- EAS information such as EAS IP address
- existing methods can be used to send the EAS information (such as EAS IP address) obtained through DNS server resolution to the UE; for example, the UE sends a DNS query request to the DNS server based on the DNS server address; the DNS server obtains the EAS information accordingly. (such as EAS IP address), and feedback is transmitted to the UE; the specific content will not be repeated here.
- EAS information such as EAS IP address
- This example introduces the process of SMF initiating rediscovery of EAS information (such as EAS IP address), which may include the following steps:
- SMF can determine that the current PSA UPF cannot support access based on the application identifier associated with the dynamic group, group member UE IP, information on PDU sessions established by group members, EDI, etc. Enter the target EAS, DNAI and/or L-DN, need to switch to a different PSA UPF, or the EAS IP address needs to be updated.
- the DNAI can be determined based on the relevant information of the dynamic group to ensure that the PDU session established by the members of the dynamic group selects the same DNAI, or can access the DNAI of the same EAS or L-DN.
- SMF can select the corresponding PSA UPF based on the DNAI determined in step 1.
- SMF sends PDU Session Modification Command (PDU Session Modification Command) To the UE, the UE determines whether it needs to rediscover the EAS based on the received information.
- PDU Session Modification Command PDU Session Modification Command

部分一;
移动边缘计算(MEC)技术通过将计算存储能力与业务服务能力向网络边缘迁移,尽可能不用将数据回传到云端,减少数据往返云端的等待时间和网络成本。基于5G的分布式云基础设施,在边缘云化构建5G用户面和5G
MEC节点,5G MEC节点提供MEC应用平台实现对第三方应用的部署和管理能力。用户可通过MEC应用获得服务。
5G定义了应用(Application)功能(Function),它向非授信域(网络开放功能NEF)或者向授信域(策略控制功能PCF)发送应用功能(AF)请求(Request),其中包含目标数据网络名称(Data Network Name,DNN)、应用标识(ID)、接口(N6)路由需求、应用位置等一系列参数。PCF根据AF提供的这些信息参数,结合自身策略控制,为目标协议数据单元(PDU)会话(Session)业务流生成策略与计费控制(PCC)规则,并通过会话管理功能(SMF)为其选择一个合适的用户面功能(UPF)。MEC提供应用基础设施资源编排、应用实例化、应用规则配置等功能。因此,当MEC部署在5G系统中时,MEC也可以充当Application Function角色,代表部署在MEC上的应用与5G系统控制面交互。
具体参见图2和图3所示的5G系统非漫游场景下结合边缘计算的网络架构图,其中,图2表示:非漫游场景中,通过上行数据分类器或分支点(UL CL/BP)访问边缘计算服务器;图3表示:非漫游场景中,访问边缘计算服务器(无UL CL/BP参与);针对图2和图3所示的5GS架构中的主要网络功能介绍如下:
AMF:Access and Mobility Management Function,接入与移动性管理功能;支持注册、连接管理等。
UPF:User Plan Function,用户面功能;支持与数据网络互连的外部协议数据单元(PDU)会话节点,报文路由和转发。
SMF:Session Management Function,会话管理功能;支持会话建立、删除,用户面选择与控制,终端(UE)IP分配等。
AF:Application Function,应用功能;支持与核心网交互以提供业务。基于运营商部署情况,可信AF可以与相关网络功能(NF)进行直接交互,而非可信AF不能直接与NF交互,而应使用对外公开框架通过网络开放功能(NEF)进行。
PCF:Policy Control Function,策略控制功能;支持统一的策略框架,以管理网络行为,提供策略规则,以便控制面NF执行。
NRF:Network Repository Function,网络存储功能;支持服务发现功能。
UDM:Unified Data Management,统一数据管理;支持存储UE的信息,例如签约信息,已建立PDU会话的信息等。
NEF:Network Exposure Function,网络开放功能;支持提供安全地将网络提供的业务和能力暴露给外部网络相关的功能。
UDR:Unified Data Repository,统一数据库UDR;支持签约数据的存储,UDM对签约数据的检索,策略信息的存储,以及PCF对策略信息的检索。
EASDF:Edge Application Server Discovery Function,边缘应用服务器发现功能;支持基于SMF指示,处理域名系统(DNS)消息。
EAS:Edge Application Server,边缘应用服务器;支持提供边缘业务。
Local part of DN:简称L-DN;表示部署在本地的数据网络中的一组网络实体集合。本地访问DN提供对local part of DN的访问。
另外,AN表示:接入网络(Access Network);ULCL/BP表示,上行数据分类器或分支点;PSA表示:PDU会话锚点(PDU Session Anchor);C-PSA表示:中心PDU会话锚点;Central DN表示:中心数据网;L-PSA表示:本地PDU会话锚点。
此外,为了支持选择性数据路由到数据网络(Data Network,DN),SMF可以控制PDU会话的数据路径,以保证PDU会话能够同时对应多个N6接口,每个支持PDU会话的锚点提供到同一个DN的不同接入路径,实现本地分流;可通过上行数据分类器(Uplink Classifier,UL CL)功能,和/或网络协议版本(IPv)6多归属功能分支点(Branching Point,BP)来实现,此架构称为会话疏导(session breakout)连接模型。
当前存在一些应用场景需要支持对于一个非预设动态UE组,当其使用的PSA UPF和边缘应用服务器(Edge Application Server,EAS)需要迁移(relocation)时,保证relocation的低时延。场景示例如下:
互动多用户游戏:可通过应用识别的不同UE,例如,在一个地理区域内的UE,需要访问相同的游戏服务以进行交互,UE需要连接到相同的应用服务器,或是关联到相同数据网络接入标识(DN Access Identifier,DNAI)的应用服务器,或是属于相同数据网络本地部分(Local part of DN,L-DN)的
应用服务器,以减少应用服务器端交互的延时。
网络会议:不同UE接入哪个网络会议(e-meeting)的终端无法预先确定,但如果接入同一个会议的UE接入同一台e-meeting服务器,则可以减少应用服务器端的交互时延,同时也减少了应用服务器之间的通信量,将大大降低成本。
部分二;
目前,应用可以请求5G系统(5GS)改变对一个或一组(通过内部组标识Internal Group Identifier指示)或任意(通过DNN、单网络片选择辅助信息S-NSSAI和DNAI指示)UE的流量路由。
EAS部署信息(EAS Deployment Information,EDI)指示边缘业务如何部署在每个本地(Local)DN中。AF可以创建、更新或删除EAS部署信息,并分发至SMF。网络开放功能NEF负责管理和存储EDI到统一数据库UDR中。
SMF能从NEF获取EDI,或者有本地预配置信息。EDI可以用于在EASDF(边缘应用服务器发现功能)上创建域名系统(DNS)消息处理规则(message handling rule)。SMF配置message handling rules到EASDF去处理关联到UE的DNS信息。
SMF根据关联到DNN和/或S-NSSAI的本地配置、EDI、UE位置、PDU会话信息等创建DNS message handling rule。DNS message handling rule包括:基于UE IP地址或全限定域名(Fully Qualified Domain Name,FQDN)范围(range)识别目标DNS查询(Query);基于EAS IP地址范围(EAS IP address range)和/或FQDN range识别DNS响应(DNS Response),动作(Action)指示(比如包括报告动作Reporting Action,转发动作Forwarding Action,和/或,控制动作Control Action)。

在此说明,上述会话管理功能设备侧、边缘应用服务器发现功能设备侧、应用功能设备侧与第一设备侧的信息处理方法之间,相似内容可相互参见。
下面结合对本申请实施例提供的所述信息处理方法进行举例说明。
针对上述技术问题,本申请实施例提供了一种信息处理方法,具体可实现为一种支持边缘应用服务器和用户面功能(UPF)切换的方法,主要涉及:针对一个非预设的动态UE组在使用相同的边缘业务时,为了减少应用服务器端的交互时延,非预设的动态UE组需要访问相同的EAS和/或、DNAI和/或L-DN以使用边缘业务。此外,由于某种原因,导致EAS或者PSA UPF relocation;则在切换触发后,动态UE组仍然需要重新发现(即接入)相同的EAS、DNAI和/或L-DN(即相同的EAS和/或DNAI和/或L-DN)。基于此需求,本方案可能的场景如下:
1、对于应用触发的EAS relocation(例如,EAS处于拥塞或停机状态)场景,存在以下两种情况:
1)触发PSA UPF relocation和DNAI改变;
2)没有触发PSA UPF relocation,例如,PSA UPF支持相同的DNAI,或者属于相同的L-DN。
2、对于PSA relocation和DNAI改变(例如,由于UE移动性导致UPF relocation)场景,存在以下三种情况:
1)触发EAS relocation;
2)没有触发EAS relocation,例如,EAS支持不同的DNAI。
3)触发L-DN改变,例如,源EAS和目标EAS(即切换后的EAS)位于不同的L-DN。
本方案中,不同UE建立不同PDU会话可通过不同PSA UPF接入相同的EAS和/或L-DN。
具体示例如图8所示,UE1通过PSA UPF1(支持DNAI1)建立PDU会话接入EAS1,UE2和UE3通过PSA UPF2(支持DNAI2)建立PDU会话接入EAS2,由于EAS1和EAS2均部署L-DN1,可以保证应用服务器端的低时延交互。
当EAS1和EAS2需要切换到EAS3,或者UE3移动到EAS3服务区域,则UE1、UE2、UE3通过PSA UPF3重新建立PDU会话接入EAS3。
其中,相同的EAS IP地址(也可称为EAS地址)表示接入同一EAS,相同的DNAI表示可接入支持此DNAI的一个或多个EAS,而相同的L-DN表示可接入部署在此L-DN的一个或多个EAS。
下面对本申请实施例提供的方案进行具体举例说明。
举例一
本举例介绍的是SMF向EASDF配置相同DNS服务器的方式来发现EAS信息(如EAS IP地址);具体如图9所示,包括如下操作:
1、UE向SMF发送PDU会话建立请求。
2、在PDU会话建立请求过程中,SMF选择边缘应用服务器发现功能EASDF(设备)。
3、SMF调用DNS上下文创建请求(Neasdf_DNSContext_Create Request),将终端IP地址(UE IP address)、用户永久标识符(SUbs cription Permanent Identifier,SUPI)、DNN、通知端点(notification endpoint),和/或DNS message handling rule等信息发送至EASDF。
具体的,SMF可以基于:SMF本地策略,和/或包含在PCF向SMF提供的PCC策略(对应于上述分组触发信息),,确定发起PDU会话的UE是否属于某一动态组(对应于上述第一动态终端组);并且生成相应的DNS
message handling rule,用于指示对于属于同一动态组的UE,需要将由UE发起的DNS查询(Query)消息发送至相同的本地DNS服务器(Local DNS server)或者通过扩展DNS客户端子网选项(EDNS Client Subnet option)增加指示信息(对应于上述目标指示信息)。例如,在Forwarding Action中包含action:DNS Query信息(即DNS Query消息)中的目标FQDN匹配特定应用关联的FQDN集的情况下,执行1)DNS Query信息发送至所指示的Local DNS server,或者,2)通过EDNS Client Subnet option增加指示信息,指示特定的IP range。这里的1)和2)分别对应“将由UE发起的DNS Query消息发送至相同的Local DNS server或者通过EDNS Client Subnet option增加指示信息”的前后两种方案。
其中,确定动态组(的)规则(对应于上述分组信息)可包括:
(1)(终端的)位置信息,例如,提供兴趣区域(Area Of Interest,AoI),指示在此AoI(即特定跟踪区域Tracking Area或者小区cell)中的UE属于(同)一个动态组(对应于终端动态组)。再如,不同UE之间的相对位置在一定距离内,这些UE属于一个动态组。再如,UE处于特定地理区域的UE属于一个动态组。
(2)(终端关联的)应用信息,例如,使用相同的Application Identifier(应用标识符)集(包含一个或多个Application Identifier),DNN,S-NSSAI,和/或全限定域名(Fully Qualified Domain Name,FQDN)集(包含一个或多个FQDN)的UE,属于一个动态组。
(3)结合位置信息和应用信息,同时满足(1)位置信息和(2)应用信息的UE,属于一个动态组。
(4)时间信息(对应于上述第一时间段信息),例如,满足在特定时间段内,并满足(2)应用信息的UE,属于一个动态组。
(5)对应于上述终端关联的特定组标识(Group Identifier),例如,属于特定外部组标识符(external group identifier)的UE,具体比如同时关联external group identifier A和external group identifier B的UE,属于一个动态组。
4、EASDF为此PDU会话创建DNS上下文(context)以存储接收的UE IP address、DNS message handling rule等信息。EASDF向SMF回复DNS上
下文创建响应(Neasdf_DNSContext_Create Response)。
5、SMF将EASDF的IP地址作为DNS服务器地址包含在PDU会话建立接收消息,即PDU会话建立响应(PDU Session Establishment Accept message)中,发送至UE。
6、UE发送DNS询问消息(DNS Query message)至EASDF。
7、如果DNS Query信息与DNS message handling rule的DNS消息检测模板(DNS message detection template)匹配,则EASDF调用DNS上下文通知请求(Neasdf_DNSContext_Notify Request)将DNS Query的信息(例如,目标的FQDN)上报至SMF。其中,只有DNS Query与DNS message handling rule中规则(即DNS message detection template)匹配时才上报Neasdf_DNSContext_Notify Request;本举例中默认这个步骤是需要执行的,但并不以此为限。
8、SMF向EASDF回复DNS上下文通知响应(Neasdf_DNSContext_Notify Response)。
9、SMF根据接收的FQDN,以及其他UE所建立PDU会话中接收的FQDN信息,在确定请求的FQDN是关联到同一个动态组(例如,请求的FQDN包含在特定FQDN集)的情况下时,或者根据UE位置(例如,UE发生移动),确定UE关联到一个动态组的情况下时,则需要提供相同EAS信息(如EAS IP地址)、接入相同的DNAI和/或接入相同的L-DN,因此要更新DNS message handling rule,例如,修改Forwarding Action中的Local DNS IP地址,或者增加相同的EDNS Client Subnet option信息。SMF通过调用DNS上下文更新请求(Neasdf_DNSContext_Update Request)将新的DNS message handling rule发送至EASDF。
这里,可以理解为:根据FQDN重新确定了一下动态UE组,并据此更新DNS message handling rule进行发送。对应于上述获取至少一个全限定域名FQDN;根据所述至少一个FQDN,更新所述第一动态终端组;针对更新后的所述第一动态终端组,更新所述DNS消息处理规则;将更新后的DNS消息处理规则,发送给EASDF设备。
10、EASDF向SMF回复DNS上下文更新响应
(Neasdf_DNSContext_Update Response)。
11、EASDF根据DNS message handling rule处理接收的DNS Query message。对于发送的DNS Query message满足DNS message handling rule,则需要这些DNS Query信息发送至相同的Local DNS server或者通过EDNS Client Subnet option增加指示信息(对应于上述目标指示信息)。例如,根据Forwarding Action,如果DNS Query信息中的目标FQDN匹配特定应用关联的FQDN集的情况下,执行1)DNS Query信息发送至SMF指示的Local DNS server,或者,2)通过EDNS Client Subnet option增加指示信息,指示特定的IP range。
12、EASDF接收由DNS系统(DNS服务器)确定的EAS信息(如EAS IP地址),并将其包含在发送给UE的DNS Response中。
13、如果DNS Response中的EAS信息(如EAS IP address)或者FQDN匹配DNS message detection template,则EASDF调用Neasdf_DNSContext_Notify request将DNS消息报告(DNS message reporting)发送至SMF。上报信息(即DNS消息报告)中可以包含多个EAS信息(如EAS IP address),并且可能包含FQDN和EDNS Client Subnet option。
14、SMF保存属于同一动态组的EAS信息、各个PDU会话信息,以及UE信息等。SMF向EASDF回复Neasdf_DNSContext_Notify Response。
15、SMF确定DNAI和N6路由(routing)信息,并且可选地执行UL CL/BP(即UL CL或BP)和Local PSA UPF的选择和插入(进而保证属于同一动态组的PDU会话选择相同DNAI,或者可接入相同的EAS集或L-DN的DNAI)。对应于上述根据所述处理规则,进行上行数据分类器UL CL或分支点,以及PDU会话锚点UPF中至少一项的选择和/或插入。
具体的,SMF会基于属于同一动态组的EAS信息和各个PDU会话信息等确定DNAI(对应于上述根据所述第一动态终端组中的至少一个终端的第一信息,针对UPF设备或EASDF设备配置处理规则),保证对属于同一动态组的PDU会话选择相同DNAI,或者可接入相同的EAS集或L-DN的DNAI。
可根据DNS message handling rule确定EAS信息。
16、获得EAS信息(如EAS IP地址),发送至UE。
具体的,可采用已有方式,EASDF将包含EAS IP地址的DNS Response发送至UE,在此不再赘述。
举例二
本举例介绍的是SMF向EASDF配置相同EAS信息(如一个或多个EAS IP地址)的方式以发现EAS信息(如EAS IP地址);具体的,本举例与举例一之间存在相似之处,基于举例一,主要有以下区别:
步骤9、SMF根据接收的FQDN,以及其他UE所建立PDU会话中接收的FQDN信息,在确定请求的FQDN是关联到同一个动态组(例如,请求的FQDN包含在特定FQDN集)的情况下时,确定需要提供相同的EAS信息(例如,一个或多个EAS IP地址),则更新DNS message handling rule,将EAS信息包含在DNS message handling rule中。
具体的,SMF指示对于(UE发送的FQDN)满足DNS message handling rule,则将EAS信息(包含一个或多个EAS IP地址,例如,多个EAS IP地址对应相同的DNAI,或部署在同一L-DN)通过EASDF发送至对应UE。例如,在Forwarding Action增加新action:如果DNS Query信息中的目标FQDN匹配特定应用关联的FQDN集,则将特定EAS信息(如EAS IP range,包含一个或多个EAS IP地址)通过EASDF发送至UE。
此外,SMF可能提供EAS信息(如EAS IP range)的有效时间信息(对应于上述处理规则自身的有效时间信息),有效时间信息可以为一个指示标识,用于指示在有效时间内EASDF可以对请求相应的FQDN的UE直接返回EAS信息(如EAS IP),而超出有效时间时,则EASDF将发送DNS Query到DNS服务器,重新获得解析的EAS信息(如EAS IP)并返给UE。另外,有效时间信息也可以为一个时间长度,例如,有效时间(valid time)=1秒,即在1秒内EASDF可以直接返回IP到UE。对应于上述EASDF确定所述处理规则的有效时间;在所述处理规则位于所述有效时间内的情况下,根据所述处理规则,向所述第一动态终端组中的至少一个终端发送EAS信息;在所述处理规则超出所述有效时间的情况下,向DNS服务器发送所述第一动态终端组中的至少一个终端对应的DNS查询消息;接收所述DNS服务器反馈的EAS信息,并发送给所述第一动态终端组中的至少一个终端。
具体的,SMF可通过调用Neasdf_DNSContext_Update Request将新的DNS message handling rule发送至EASDF。
步骤11、EASDF根据DNS message handling rule处理接收的DNS Query message。例如,根据Forwarding Action:如果DNS Query信息中的目标FQDN匹配特定应用关联的FQDN集,则将特定EAS信息(包含一个或多个EAS IP地址)包含在DNS Response。
可选地,EASDF可根据有效时间信息判断是否直接返回EAS信息(如一个或多个EAS IP地址),或是需要发送DNS Query到DNS服务器进行获取。如果SMF没有提供有效时间信息,EASDF也可以基于本地配置策略(对应于上述EASDF的本地策略配置),确定有效时间;但并不以此为限。
举例一中步骤12-14,在本举例中不执行。
步骤16、EASDF将确定的EAS信息(如EAS IP)包含在DNS Response发送至UE。
其中,步骤15与举例一相同。
举例三
本举例介绍的是通过Local DNS Server发现EAS信息(如EAS IP地址);如图10所示,包括如下操作:
1、UE向SMF发送PDU会话建立请求。
2、SMF确定DNAI,选择UPF;并插入UL CL或BP,配置流量路由规则。
具体的,SMF如果根据接收的FQDN,以及终端位置等信息,基于同举例一的“确定动态组规则”,确定UE属于特定动态UE组,则相应确定DNAI(例如,确保属于同一动态组的UE接入相同的EAS、DNAI和/或L-DN)并基于所确定的DNAI选择和插入PSA UPF、以及确定的DNS server,以确保动态UE组使用相同的DNS server。对应于上述根据所述处理规则,执行以下至少一项操作:进行上行数据分类器UL CL或分支点,以及PDU会话锚点UPF中至少一项的选择和/或插入;进行DNS服务器的确定。
可选地,SMF确定插入UL CL/BP。SMF向UL CL/BP配置规则,包括:SMF向UL CL或BP配置流量路由规则,在流量路由规则中提供相同的DNS
server address(配置到UL CL)或者相同的IP prefix(配置到BP)。对应于上述根据所述处理规则,向上行数据分类器UL CL或分支点BP配置流量路由规则。其中,IP prefix表示IP地址前缀。
3、SMF向UE反馈PDU会话建立请求响应。
具体的,SMF将相同的DNS server address包含在PDU会话建立接收信息,对应于PDU会话建立请求响应(PDU Session Establishment Accept message)发给UE;当然,也可以通过PDU会话修改(PDU Session Modification)过程发给UE,例如,包含Local DNS server address在协议配置选项(Protocol Configuration Options,PCO)中;但并不以此为限。
4、获得EAS信息(如EAS IP地址),发送至UE。
具体的,可采用已有方式,将通过DNS服务器解析获得的EAS信息(如EAS IP地址)发送给UE;比如,UE根据DNS server address向DNS服务器发送DNS查询请求;DNS服务器据此获得EAS信息(如EAS IP地址),并反馈传给UE;具体内容在此不再赘述。
举例四
本举例介绍的是SMF发起重新发现EAS信息(如EAS IP地址)的过程,可包括如下步骤:
1、由于UE为关联到特定应用的(终端)动态组,SMF可根据动态组关联的应用标识、组成员UE IP、组成员建立的PDU会话的信息、EDI等,确定当前PSA UPF无法支持接入目标EAS、DNAI和/或L-DN,需要切换到其他PSA UPF,或者EAS IP地址需要更新。之后,可根据动态组的相关信息确定DNAI,以保证动态组成员建立的PDU会话选择相同DNAI,或者可接入相同的EAS或L-DN的DNAI。对应于上述在确定所述第一动态终端组中的至少一个终端对应的UPF(包括PSA UPF,和/或UL CL/BP UPF)或EAS地址需要更换的情况下,根据所述第一动态终端组,针对UPF设备或EASDF设备配置处理规则。
2、SMF发起PDU会话修改过程。
具体的,SMF可以根据步骤1确定的DNAI选择相应的PSA UPF。
3、SMF发送PDU会话修改指令(PDU Session Modification Command)
到UE,UE根据接收的信息确定是否需要重新发现EAS。
举例五
本举例介绍的是AF指示对关联到相同应用的UE会话需要接入相同的EAS、DNAI和/或L-DN;具体如图11所示,包括如下操作:
1、AF创建AF请求,也可称为AF创建请求信息。
具体的,可以是在AF请求中新增信息动态组信息(Information on dynamic group),其可包含以下一种或两种信息:
1)指示信息,指示对关联到相同应用的UE会话需要接入相同的EAS、DNAI和/或L-DN(对应于上述指示信息用于指示会话管理功能设备执行根据第一动态终端组,针对用户面功能UPF设备或边缘应用服务器发现功能EASDF设备配置处理规则)。
2)指示动态组形成规则(对应于上述分组信息),规则可包括:
(1)(终端的)位置信息,例如,提供AoI(Area Of Interest),指示在此AoI(即特定Tracking Area或者cell)中的UE属于一个动态组。再如,不同UE之间的相对位置在一定距离内,这些UE属于一个动态组。再如,UE处于特定地理区域的UE属于一个动态组。
(2)(终端关联的)应用信息,使用相同的Application Identifier集(包含一个或多个Application Identifier),DNN,S-NSSAI,和/或FQDN集(包含一个或多个FQDN)的UE,属于一个动态组。
(3)结合位置信息和应用信息,同时满足(1)位置信息和(2)应用信息的UE,属于一个动态组。
(4)时间信息(对应于上述第一时间段信息),例如,满足在特定时间段内,并满足(2)应用信息的UE,属于一个动态组。
(5)对应于上述终端关联的特定组标识(Group Identifier),例如,属于特定external group identifier的UE,具体比如同时属于external group identifier A和external group identifier B的UE,属于一个动态组。
可选地,Information on dynamic group可提供应用信息(如果没有提供EDI),包括关联到相同应用的一组应用标识(例如,FQDN集,Application ID),对应的DNS服务器信息(例如,DNS IP地址),EAS IP地址等。
关于Information on dynamic group,具体可参见下表:
2-4、可采用已有方式,如图11所示,通过NEF、UDR将AF请求信息发送给PCF(对应于上述将动态组信息,发送给第一设备);PCF据此相应生成PCC规则(对应于上述根据所述动态组信息,得到策略与计费控制PCC策略信息),PCC规则中可包含上述指示信息和/或动态组形成规则。
5、PCF将PCC规则发送至SMF(对应于上述将所述PCC策略信息发送给会话管理功能SMF设备)。
6、SMF重新配置用户面。
具体的,SMF可考虑动态组成员建立的PDU会话选择相同DNAI,并相应插入或替换或移除UPF,以及针对动态UE组向UPF配置新的流量导流规则,对应于上述流量分流规则(traffic steering rule),但并不以此为限。
由上,本申请实施例提供的方案涉及以下流程:
1、SMF确定具体相同特征的UE属于同一动态UE组,并向UPF或EASDF配置规则,确保动态UE组接入相同的EAS、DNAI和/或L-DN,或者确保流量分流(对应于上述使得针对所述第一动态终端组的数据流实现流量分流)。
2、基于1,SMF根据接收的FQDN,以及其他UE所建立PDU会话中接收的FQDN信息,确定请求的FQDN关联到同一FQDN集。
3、基于2,SMF向EASDF相应更新配置规则(DNS message handling rule)。
4、基于2,SMF向UL CL/BP UPF配置规则(即流量路由规则)。
5、基于1,SMF根据动态组关联的应用标识,组成员UE IP,组成员建立的PDU会话的信息,EDI等确定DNAI。
6、AF请求中新增指示信息Information on EAS selection,指示对关联到相同应用的UE会话需要接入相同的EAS、DNAI和/或L-DN。
综上所述,本方案针对一个非预设的动态UE组在使用相同的边缘业务,以及在EAS和PSA UPF迁移(relocation)时,无法保证为非预设的动态UE组提供低通信时延的问题;提出为非预设的动态UE组发现或者重新发现相同的EAS、DNAI和/或L-DN,以及协同的UPF和EAS切换,实现减少应用服务器端的交互时延和切换时延,以确保业务的连续性。并且支持对非预设的动态UE组进行即流量卸载或者流量分流至边缘(traffic offload)。
