当UE与网络侧之间交互的服务质量(quality of service，QoS)需要修改时，UE或网络侧将请求发起PDU会话修改流程。在此流程中，会涉及会话管理策略修改(session management policy modification)。另外，在UE发起的业务请求(service request)、上行分类器(Uplink Classifier，ULCL)添加或分支点(Branching Point，BP)添加等流程中，同样会涉及会话管理策略修改。在会话管理策略修改的过程中，当触发事件发生时，会话管理功能(session management function，SMF)向策略控制功能(policy control function，PCF)通知触发事件。PCF收到通知之后，进行策略决策。策略决策可能会涉及策略的更新。若策略需要更新，PCF向SMF发送更新后的策略。When the quality of service (QoS) of the interaction between the UE and the network side needs to be modified, the UE or the network side will request to initiate a PDU session modification procedure. In this process, session management policy modification is involved. In addition, the session management policy modification is also involved in the process of the service request, the uplink classifier (ULCL) addition, or the branching point (BP) addition. In the process of modifying the session management policy, when a trigger event occurs, the session management function (SMF) notifies the trigger control event to the policy control function (PCF). After the PCF receives the notification, it makes a policy decision. Policy decisions may involve updates to the strategy. If the policy needs to be updated, the PCF sends the updated policy to the SMF.
然而，当前会话管理策略修改的执行机制还未明确，导致SMF的处理信令效率较低。However, the implementation mechanism of the current session management policy modification is not clear, resulting in low efficiency of processing signaling of the SMF.

步骤301，当SMF检测到PCF之前向SMF订阅的事件发生时，SMF通过调用Nsmf_EventExposure_Notify的服务，向PCF通知该事件及该事件的相关信息。该服务用于向订阅过事件上报服务的网元(例如，PCF)进行上报。调用该服务的输入包括事件的标识信息。Step 301: When an event that the SMF subscribes to the SMF before the SMF detects the SMF, the SMF notifies the PCF of the event and related information of the event by calling the service of the Nsmf_EventExposure_Notify. The service is used to report the network element (for example, PCF) that subscribes to the event reporting service. The input to invoke the service includes identification information for the event.
步骤302，PCF保存事件的相关信息，并向SMF返回Nsmf_EventExposure_Notify响应。In step 302, the PCF saves the relevant information of the event and returns an Nsmf_EventExposure_Notify response to the SMF.
步骤303，PCF进行策略决策(policy decision)。策略决策可能会涉及会话相关策略的更新。或者，策略决策也可能不涉及会话相关策略的更新。In step 303, the PCF performs a policy decision. Policy decisions may involve updates to session-related policies. Alternatively, policy decisions may not involve updates to session-related policies.
步骤304，若会话相关策略需要更新，PCF通过调用Npcf_SMPolicyControl_UpdateNotify的服务，向SMF发送更新后的会话相关策略。Step 304: If the session related policy needs to be updated, the PCF sends the updated session related policy to the SMF by calling the service of Npcf_SMPolicyControl_UpdateNotify.
步骤305，SMF向PCF返回Npcf_SMPolicyControl_UpdateNotify响应，执行更新后的会话相关策略。Step 305: The SMF returns an Npcf_SMPolicyControl_UpdateNotify response to the PCF, and executes the updated session related policy.
然而，步骤303会产生不同的策略决策的结果。当需要更新会话相关策略时会触发步骤304，当不需要更新会话相关策略时可以不执行步骤304。当前会话管理策略修改的执行机制还未明确SMF是否需要等到接收到步骤304的通知之后才执行后续的动作。或者说，还未明确PCF在会话相关策略不需要更新的时候是否会执行步骤304。若无论会话相关策略是否更新，PCF都执行步骤304，SMF等到接收到步骤304的通知之后才执行后续的动作，则会导致不必要的信令开销，且对于策略更新SMF需要进行不必要的等待，降低了信令处理效率。若SMF无需等到接收到步骤304的通知，就先执行后续的动作，则若SMF后续收到更新的会话相关策略，需要重新执行这些动作，也会导致不必要的信令开销。因此，SMF的处理信令效率较低。However, step 303 will result in different policy decisions. Step 304 is triggered when the session related policy needs to be updated, and step 304 may not be performed when the session related policy is not required to be updated. The execution mechanism of the current session management policy modification has not yet clarified whether the SMF needs to wait until the notification of step 304 is received before performing the subsequent action. In other words, it is not clear whether the PCF will perform step 304 when the session related policy does not need to be updated. If the session-related policy is updated, the PCF performs step 304, and the SMF waits until the notification of step 304 is received to perform subsequent actions, which may result in unnecessary signaling overhead, and unnecessary waiting for the policy update SMF. , reducing the efficiency of signaling processing. If the SMF does not need to wait until the notification of step 304 is received, the subsequent actions are performed first. If the SMF subsequently receives the updated session-related policy, it needs to perform these actions again, which may result in unnecessary signaling overhead. Therefore, the processing signaling of the SMF is inefficient.
图3b中的策略关联修改流程涉及AMF与PCF之间的交互。例如，AMF为图1中的AMF网元103或图2中的AMF网元103’。PCF为图1中的PCF网元105或图2中的PCF网元105’。该流程适用于漫游和非漫游的场景。在漫游场景中，PCF是指拜访的PCF。The policy association modification process in Figure 3b involves the interaction between the AMF and the PCF. For example, the AMF is the AMF network element 103 in Fig. 1 or the AMF network element 103' in Fig. 2. The PCF is the PCF network element 105 in Fig. 1 or the PCF network element 105' in Fig. 2. This process is suitable for both roaming and non-roaming scenarios. In a roaming scenario, PCF refers to the visited PCF.
如图3b所示，策略关联修改流程包括如下步骤:As shown in Figure 3b, the policy association modification process includes the following steps:
步骤311，当AMF检测到PCF之前向AMF订阅的事件发生时，AMF通过调用Namf_EventExposure_Notify的服务，向PCF通知该事件及该事件的相关信息。调用该服务的输入包括事件的标识信息。Step 311: When an event that the AMF subscribes to the AMF before the PCF detects, the AMF notifies the PCF of the event and related information of the event by calling the service of Namf_EventExposure_Notify. The input to invoke the service includes identification information for the event.
步骤312，PCF保存事件的相关信息，并向AMF返回Namf_EventExposure_Notify响应。In step 312, the PCF saves the relevant information of the event and returns a Namf_EventExposure_Notify response to the AMF.
步骤313，PCF进行策略决策。策略决策可能会涉及接入和移动性相关策略的更新。或者，策略决策也可能不涉及接入和移动性相关策略的更新。In step 313, the PCF makes a policy decision. Policy decisions may involve updates to access and mobility related policies. Alternatively, policy decisions may not involve updates to access and mobility related policies.
步骤314，若接入和移动性相关策略需要更新，PCF通过调用Npcf_AMPolicyControl_UpdateNotify的服务，向AMF发送更新后的接入和移动性相关策略。Step 314: If the access and mobility related policies need to be updated, the PCF sends the updated access and mobility related policies to the AMF by calling the service of Npcf_AMPolicyControl_UpdateNotify.
步骤315，AMF向PCF返回Npcf_AMPolicyControl_UpdateNotify响应。In step 315, the AMF returns an Npcf_AMPolicyControl_UpdateNotify response to the PCF.
类似的，步骤313会产生不同的策略决策的结果。当需要更新接入和移动性相关策略时会触发步骤314，当不需要更新接入和移动性相关策略时可以不执行步骤314。当前策略关联修改的执行机制还未明确AMF是否需要等到接收到步骤314的通知之后才执行后续的动作。或者说，还未明确PCF在接入和移动性相关策略不需要更新的时候是否会执行步骤314。若无论接入和移动性相关策略是否更新，PCF都执行步骤314，AMF等到接收到步骤314的通知之后才执行后续的动作，则会导致不必要的信令开销，且对于策略更新AMF需要进行不必要的等待，降低了信令处理效率。若AMF无需等到接收到步骤314的通知，就先执行后续的动作，则若AMF后续收到更新的接入和移动性相关策略，需要重新执行这些动作，也会导致不必要的信令开销。因此，AMF的处理信令效率较低。Similarly, step 313 produces the results of different policy decisions. Step 314 is triggered when the access and mobility related policies need to be updated, and step 314 may not be performed when the access and mobility related policies need not be updated. The execution mechanism of the current policy association modification has not yet clarified whether the AMF needs to wait until the notification of step 314 is received before performing the subsequent action. In other words, it has not been determined whether the PCF will perform step 314 when the access and mobility related policies do not need to be updated. If the access and mobility related policies are updated, the PCF performs step 314, and the AMF waits until the notification of step 314 is received to perform subsequent actions, which may result in unnecessary signaling overhead and need to be performed for the policy update AMF. Unnecessary waiting reduces the efficiency of signaling processing. If the AMF does not need to wait until the notification of step 314 is received, the subsequent actions are performed first. If the AMF subsequently receives the updated access and mobility related policies, the actions need to be re-executed, which may result in unnecessary signaling overhead. Therefore, AMF's processing signaling is less efficient.
根据本申请实施例的方法，可针对特定的事件生成指示信息，使得SMF/AMF根据指示信息，直到从PCF接收到第一终端的策略信息，才执行与所述第一终端关联的后续操作，提高了SMF/AMF的处理信令效率，进而提高了用户体验。According to the method of the embodiment of the present application, the indication information may be generated for a specific event, so that the SMF/AMF performs the subsequent operation associated with the first terminal according to the indication information until the policy information of the first terminal is received from the PCF, The processing signaling efficiency of the SMF/AMF is improved, thereby improving the user experience.
下面以图1或图2所示的5G通信***为例，通过一些实施例对本申请的技术方案进行详细说明。下面这几个实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。The technical solution of the present application is described in detail by using some embodiments of the 5G communication system shown in FIG. 1 or FIG. 2 . The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.
图4为本申请实施例提供的一种策略相关的通信方法的流程图。本申请涉及策略控制功能网元和控制面网元之间的交互。例如，策略控制功能网元可以是图1中的PCF网元105或图2中的PCF网元105’。该控制面网元为会话管理功能网元或移动性管理功能网元。例如，会话管理功能网元可以是图1中的SMF网元104或图2中的SMF网元104’。移动性管理功能网元可以是图1中的AMF网元103或图2中的AMF网元103’。FIG. 4 is a flowchart of a policy related communication method according to an embodiment of the present application. The present application relates to interaction between a policy control function network element and a control plane network element. For example, the policy control function network element can be the PCF network element 105 in Figure 1 or the PCF network element 105' in Figure 2. The control plane network element is a session management function network element or a mobility management function network element. For example, the session management function network element can be the SMF network element 104 of Figure 1 or the SMF network element 104' of Figure 2. The mobility management function network element may be the AMF network element 103 in Fig. 1 or the AMF network element 103' in Fig. 2.
本申请实施例的方案适用于漫游和非漫游的场景。当控制面网元为会话管理功能网元时，在本地路由的漫游场景中，策略控制功能网元是指拜访的策略控制功能网元；在归属地路由的漫游场景中，策略控制功能网元是指归属的策略控制功能网元。当控制面网元为移动性管理功能网元时，在漫游场景中，策略控制功能网元是指拜访的策略控制功能网元。The solution of the embodiment of the present application is applicable to scenarios of roaming and non-roaming. When the control plane network element is the session management function network element, in the local routing roaming scenario, the policy control function network element refers to the visited policy control function network element; in the home route routing roaming scenario, the policy control function network element Refers to the home policy control function network element. When the control plane network element is the mobility management function network element, in the roaming scenario, the policy control function network element refers to the visited policy control function network element.
如图4所示，该方法可以包括以下步骤：As shown in FIG. 4, the method may include the following steps:
步骤401，策略控制功能网元根据第一事件的标识信息确定指示信息。该指示信息用于指示：直到控制面网元从策略控制功能网元接收第一终端的策略信息，控制面网元网元才执行与第一终端关联的后续操作。Step 401: The policy control function network element determines the indication information according to the identifier information of the first event. The indication information is used to indicate that the control plane network element receives the policy information of the first terminal from the policy control function network element, and the control plane network element network element performs the subsequent operation associated with the first terminal.
第一事件的标识信息用于标识第一事件，例如，事件标识(event ID)。The identification information of the first event is used to identify the first event, for example, an event ID.
例如，策略控制功能网元首先获取第一事件的标识信息。策略控制功能网元如何获取第一事件的标识信息将结合图5、图6进一步描述。For example, the policy control function network element first obtains the identification information of the first event. How the policy control function network element obtains the identification information of the first event will be further described in conjunction with FIG. 5 and FIG. 6.
当策略控制功能网元根据获取到的第一事件的标识信息判断第一终端的策略待更新，则确定指示信息。When the policy control function network element determines that the policy of the first terminal is to be updated according to the acquired identifier information of the first event, the indication information is determined.
当控制面网元为会话管理功能网元时，第一终端的策略可以是会话相关的策略。例如，当标识信息标识第一事件为QoS改变(QoS change)、会话聚合最大比特速率 (aggregate maximum bit rate，AMBR)改变(session-AMBR change)、信用不足(Out of credit)或UE的网络协议(internet protocol，IP)地址改变(UE IP address change)，策略控制功能网元判断可能需要更新会话相关策略，则生成指示信息。若第一事件为公用陆地移动网(public land mobile network，PLMN)改变(PLMN change)或位置改变(location change)，策略控制功能网元判断不需要更新会话相关策略，因而不生成指示信息。When the control plane network element is a session management function network element, the policy of the first terminal may be a session-related policy. For example, when the identification information identifies the first event as a QoS change, an aggregate maximum bit rate (AMBR) change, an out of credit, or a network protocol of the UE. (Internet protocol, IP) address change (UE IP address change), the policy control function network element determines that the session related policy may need to be updated, and generates indication information. If the first event is a public land mobile network (PLMN) change or a location change, the policy control function network element determines that the session related policy does not need to be updated, and thus does not generate indication information.
当控制面网元为移动性管理功能网元时，第一终端的策略可以是接入和移动性相关的策略。例如，当标识信息标识第一事件为服务区域限制改变(Service Area Restriction change)或无线接入技术/频率选择优先级(RAT/Frequency selection Priority，RFSP)指数改变(RFSP index change)，策略控制功能网元判断可能需要更新接入和移动性相关的策略，则生成指示信息。若第一事件为存在上报区域(Presence Reporting Area，PRA)改变(change of UE presence in PRA)，策略控制功能网元判断不需要更新接入和移动性相关的策略，因而不生成指示信息。When the control plane network element is a mobility management function network element, the policy of the first terminal may be an access and mobility related policy. For example, when the identification information identifies that the first event is a Service Area Restriction change or a Radio Access Technology/RFS index change (RFSP index change), the policy control function The network element determines that the access and mobility related policies may need to be updated, and generates indication information. If the first event is a change of UE presence in PRA, the policy control function network element determines that the access and mobility related policies do not need to be updated, and thus does not generate indication information.
例如，该指示信息可以是一个标志位(flag)。本申请并不限制指示信息的形式。For example, the indication information can be a flag. This application does not limit the form of the indication information.
步骤402，策略控制功能网元向控制面网元发送指示信息。Step 402: The policy control function network element sends indication information to the control plane network element.
在一种可能的实现方式中，当策略控制功能网元向控制面网元调用事件开放的订阅服务时，策略控制功能网元向控制面网元发送指示信息。例如，策略控制功能网元向控制面网元发送用于请求控制面网元上报第一事件的订阅消息，该订阅消息包括指示信息。该实现方式将结合图5进一步描述。In a possible implementation manner, when the policy control function network element invokes the event open subscription service to the control plane network element, the policy control function network element sends the indication information to the control plane network element. For example, the policy control function network element sends a subscription message for requesting the control plane network element to report the first event to the control plane network element, where the subscription message includes indication information. This implementation will be further described in conjunction with FIG.
在另一种可能的实现方式中，当控制面网元调用事件开放的通知服务时，策略控制功能网元向控制面网元发送指示信息。例如，策略控制功能网元从控制面网元接收用于通知所述第一事件通知消息，向控制面网元发送通知响应消息，该通知响应消息包括指示信息。该实现方式将结合图6进一步描述。In another possible implementation manner, when the control plane network element invokes the event open notification service, the policy control function network element sends the indication information to the control plane network element. For example, the policy control function network element receives, from the control plane network element, a notification for the first event notification message, and sends a notification response message to the control plane network element, where the notification response message includes indication information. This implementation will be further described in conjunction with FIG.
控制面网元收到指示信息后，在从策略控制功能网元接收第一终端的策略信息之前，根据指示信息等待。即，控制面网元不执行第一终端的后续操作，等待策略控制功能网元返回第一终端的策略信息。After receiving the indication information, the control plane network element waits according to the indication information before receiving the policy information of the first terminal from the policy control function network element. That is, the control plane network element does not perform the subsequent operation of the first terminal, and waits for the policy control function network element to return the policy information of the first terminal.
步骤403，策略控制功能网元进行策略决策。例如，策略决策后，策略控制功能网元生成第一终端的策略信息，例如，会话相关策略，或，接入和移动性相关策略。In step 403, the policy control function network element performs policy decision. For example, after the policy decision, the policy control function network element generates policy information of the first terminal, for example, a session related policy, or an access and mobility related policy.
步骤404，策略控制功能网元向控制面网元发送第一终端的策略信息。相应的，控制面网元从策略控制功能网元接收第一终端的策略信息。Step 404: The policy control function network element sends the policy information of the first terminal to the control plane network element. Correspondingly, the control plane network element receives the policy information of the first terminal from the policy control function network element.
例如，PCF通过调用策略控制更新通知的服务(例如，图3a中步骤304的Npcf_SMPolicyControl_UpdateNotify服务或图3b中的步骤314的Npcf_AMPolicyControl_UpdateNotify服务)，向控制面网元发送第一终端的策略信息。For example, the PCF transmits the policy information of the first terminal to the control plane network element by invoking a policy control update notification service (eg, the Npcf_SMPolicyControl_UpdateNotify service of step 304 in FIG. 3a or the Npcf_AMPolicyControl_UpdateNotify service of step 314 in FIG. 3b).
步骤405，控制面网元根据指示信息，直到从策略控制功能网元接收第一终端的策略信息，才执行与第一终端关联的后续操作。Step 405: The control plane network element performs the subsequent operation associated with the first terminal according to the indication information until the policy information of the first terminal is received from the policy control function network element.
例如，当控制面网元为会话管理功能网元时，后续操作包括更新AN设备上的QoS，或，修改会话管理功能网元与用户面网元(例如，图1中的UPF网元106或图2中的UPF网元106’)之间的N4PDU会话。结合上面的例子，当第一事件为QoS改变、AMBR 改变、信用不足或UE的IP地址改变，策略控制功能网元向会话管理功能网元发送指示信息。由此，会话管理功能网元根据指示信息，需要等待至收到策略控制功能网元发送的策略之后，才更新AN设备上的QoS或修改N4PDU会话。当第一事件为PLMN改变或位置改变，策略控制功能网元不向会话管理功能网元发送指示信息。会话管理功能网元在预设时间内没有接收到指示信息，则无需等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可更新AN设备上的QoS或修改N4PDU会话。For example, when the control plane network element is a session management function network element, the subsequent operations include updating the QoS on the AN device, or modifying the session management function network element and the user plane network element (for example, the UPF network element 106 in FIG. 1 or An N4 PDU session between UPF network elements 106') in FIG. In combination with the above example, when the first event is a QoS change, an AMBR change, a credit deficiency, or an IP address change of the UE, the policy control function network element sends the indication information to the session management function network element. Therefore, the session management function network element needs to wait until the policy sent by the policy control function network element is received according to the indication information, and then update the QoS on the AN device or modify the N4 PDU session. When the first event is a PLMN change or a location change, the policy control function network element does not send indication information to the session management function network element. If the session management function network element does not receive the indication information within the preset time, it does not need to wait for the policy of the policy control function network element to send the QoS or modify the N4 PDU session on the AN device after the first event is received. .
当控制面网元为移动性管理功能网元时，后续操作包括根据第一终端的策略信息向AN设备或该第一终端发送服务区域限制信息，使得AN设备或该第一终端更新UE策略(例如，移动性策略)。结合上面的例子，当第一事件为服务区域限制改变或RFSP指数改变，策略控制功能网元向移动性管理功能网元发送指示信息。由此，移动性管理功能网元根据指示信息，需要等待至收到策略控制功能网元发送的策略之后，才向AN设备或该第一终端发送服务区域限制信息。当第一事件为PRA改变，策略控制功能网元不向移动性管理功能网元发送指示信息。移动性管理功能网元在预设时间内没有接收到指示信息，则无需等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可向AN设备或该第一终端发送服务区域限制信息。When the control plane network element is the mobility management function network element, the subsequent operation includes sending the service area restriction information to the AN device or the first terminal according to the policy information of the first terminal, so that the AN device or the first terminal updates the UE policy ( For example, mobility strategy). In combination with the above example, when the first event is a service area restriction change or an RFSP index change, the policy control function network element sends indication information to the mobility management function network element. Therefore, the mobility management function network element needs to wait for the policy sent by the network element of the policy control function to send the service area restriction information to the AN device or the first terminal according to the indication information. When the first event is a PRA change, the policy control function network element does not send the indication information to the mobility management function network element. If the mobility management function network element does not receive the indication information within the preset time, the network element that does not need to wait for the policy control function network element to send may send the notification to the AN device or the first terminal after reporting the first event. Service area restriction information.
因此，策略控制功能网元可根据事件的标识信息进行判断：对某特定的事件生成指示信息并发送至控制面网元，使得控制面网元收到指示信息后需要要等待至收到策略控制功能网元发送的策略之后才执行后续操作。对于其他特定的事件不生成指示信息，使得控制面网元无需等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可执行后续操作。由此，提高了控制面网元的处理信令效率，进而提高了用户体验。Therefore, the network element of the policy control function can be determined according to the identification information of the event: the indication information is generated for a specific event and sent to the control plane network element, so that the control plane network element needs to wait until receiving the policy control after receiving the indication information. The subsequent operations are performed after the policy sent by the function NE. The indication information is not generated for other specific events, so that the control plane network element does not need to wait for the policy sent by the policy control function network element, and the subsequent operation can be performed after the first event is received and the notification response is received. Thereby, the processing signaling efficiency of the control plane network element is improved, thereby improving the user experience.
可选的，在上述步骤401中，指示信息的确定还可进一步考虑第一终端的终端信息。也就是说，步骤401包括：策略控制功能网元根据第一事件的标识信息和第一终端的终端信息确定指示信息。Optionally, in the foregoing step 401, determining the indication information may further consider terminal information of the first terminal. That is, step 401 includes: the policy control function network element determines the indication information according to the identification information of the first event and the terminal information of the first terminal.
第一终端的终端信息包括第一终端的标识信息和与第一终端关联的签约信息中的至少一项，或，终端信息包括第一终端的第一会话的标识信息、与第一会话对应的IP地址、与第一会话关联的签约信息中的至少一项。The terminal information of the first terminal includes at least one of the identification information of the first terminal and the subscription information associated with the first terminal, or the terminal information includes the identification information of the first session of the first terminal, and the first session At least one of an IP address and subscription information associated with the first session.
换句话说，终端信息可以是UE粒度的，或者，也可以是会话粒度的。In other words, the terminal information may be UE granularity, or it may be session granularity.
UE粒度的终端信息包括第一终端的标识信息和与第一终端关联的签约信息(也可称为UE粒度的签约信息)中的至少一项。例如，与第一终端关联的签约信息包括通用公共订阅标识(Generic Public Subscription Identifier，GPSI)、无线接入技术(radio access technology，RAT)限制(RAT restriction)、禁止区域(forbidden area)中的至少一项。The UE granularity terminal information includes at least one of identification information of the first terminal and subscription information (which may also be referred to as UE granularity subscription information) associated with the first terminal. For example, the subscription information associated with the first terminal includes at least a Generic Public Subscription Identifier (GPSI), a radio access technology (RAT) restriction, a forbidden area, and a forbidden area. One.
会话粒度的终端信息包括第一终端的第一会话的标识信息(例如，session ID)、与第一会话对应的IP地址、与第一会话关联的签约信息(也可称为会话粒度的签约信息)中的至少一项。例如，与第一会话关联的签约信息包括单网络切片选择辅助信息(single-network slice selection assistance information，S-NSSAI)、数据网络名称(data network name，DNN)和会话和业务连续性(session and service  continuity，SSC)模式(SSC mode)中的至少一项。The terminal information of the session granularity includes identification information (for example, session ID) of the first session of the first terminal, an IP address corresponding to the first session, and subscription information associated with the first session (also referred to as session granularity subscription information) At least one of them. For example, the subscription information associated with the first session includes single-network slice selection assistance information (S-NSSAI), data network name (DNN), and session and business continuity (session and At least one of service continuity, SSC mode (SSC mode).
策略控制功能网元如何获取第一终端的终端信息也将结合后面的图5、图6进一步描述。How the policy control function network element obtains the terminal information of the first terminal will be further described in conjunction with FIG. 5 and FIG. 6 below.
例如，当策略控制功能网元根据获取到的第一事件的标识信息和第一终端的终端信息，判断第一终端的策略待更新，则确定指示信息。For example, when the policy control function network element determines that the policy of the first terminal is to be updated according to the acquired identification information of the first event and the terminal information of the first terminal, the indication information is determined.
举例来说，当控制面网元为会话管理功能网元时，若第一事件为使用量上报(usage report)且所述终端信息指示第一终端为签约了公平使用量策略(fair usage policy，FUP)的UE，策略控制功能网元判断可能需要更新会话相关策略，则生成指示信息。若第一事件为使用量上报且所述终端信息指示第一终端为没有签约FUP的UE，策略控制功能网元判断不需要更新会话相关策略，因而不生成指示信息。For example, when the control plane network element is a session management function network element, if the first event is a usage report and the terminal information indicates that the first terminal is a contracted fair usage policy (fair usage policy, The UE of the FUP), the policy control function network element determines that the session related policy may need to be updated, and generates indication information. If the first event is the usage report and the terminal information indicates that the first terminal is a UE that does not subscribe to the FUP, the policy control function network element determines that the session related policy does not need to be updated, and thus does not generate the indication information.
又例如，若第一事件为接入类型改变(change in type of Access Type，例如，UE从4G切换至5G)且所述终端信息指示第一终端为4G和5G采用不同费率的UE，策略控制功能网元判断可能需要更新会话相关策略，则生成指示信息。若第一事件为接入类型改变且所述终端信息指示第一终端为4G和5G采用相同费率的UE，策略控制功能网元判断不需要更新会话相关策略，因而不生成指示信息。For another example, if the first event is a change in type of Access Type, for example, the UE switches from 4G to 5G, and the terminal information indicates that the first terminal uses different rates of UEs for 4G and 5G, the policy is The control function network element determines that it may be necessary to update the session related policy, and generates indication information. If the first event is an access type change and the terminal information indicates that the first terminal uses the same rate for the 4G and the 5G, the policy control function network element determines that the session related policy does not need to be updated, and thus does not generate the indication information.
当控制面网元为移动性管理功能网元时，若第一事件为位置变化(location change)且所述终端信息指示第一终端为签约了服务区域限制(service area restriction)的UE，策略控制功能网元判断可能需要更新接入和移动性相关的策略，则生成指示信息。若第一事件为位置变化且所述终端信息指示第一终端为没有签约服务区域限制的UE，策略控制功能网元判断不需要更新接入和移动性相关的策略，因而不生成指示信息。When the control plane network element is a mobility management function network element, if the first event is a location change and the terminal information indicates that the first terminal is a UE that has subscribed to a service area restriction, policy control The function network element determines that the access and mobility related policies may need to be updated, and generates indication information. If the first event is a location change and the terminal information indicates that the first terminal is a UE that does not have a subscription service area restriction, the policy control function network element determines that the access and mobility related policies do not need to be updated, and thus does not generate indication information.
因此，策略控制功能网元可根据事件的标识信息和终端信息进行判断：对某个UE(或某个会话的)某特定的事件生成指示信息并发送至控制面网元，使得控制面网元收到指示信息后需要要等待至收到策略控制功能网元发送的策略之后才执行后续操作。否则，不生成指示信息，使得控制面网元无需等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可执行后续操作。由此，可针对不同的UE或会话执行灵活的操作，进一步提高了控制面网元的处理信令效率，进而提高了用户体验。Therefore, the network element of the policy control function may be determined according to the identifier information of the event and the terminal information: generating indication information for a specific event of a certain UE (or a session) and sending the information to the control plane network element, so that the control plane network element After receiving the indication information, you need to wait until the policy sent by the policy control function network element is received before performing the subsequent operations. Otherwise, the indication information is not generated, so that the control plane network element does not need to wait for the policy sent by the policy control function network element, and the subsequent operation can be performed after the first event is received and the notification response is received. Thereby, flexible operations can be performed for different UEs or sessions, which further improves the processing signaling efficiency of the control plane network element, thereby improving the user experience.

图7示出了根据本申请另一实施例提供的一种策略相关的通信方法的流程图。图7和图5、图6的差别在于，在会话管理策略更新的流程中，由SMF确定指示信息并通过通知消息告知PCF。例如，该方法包括如下步骤：FIG. 7 is a flowchart of a policy related communication method according to another embodiment of the present application. The difference between FIG. 7 and FIG. 5 and FIG. 6 is that, in the flow of the session management policy update, the indication information is determined by the SMF and notified to the PCF by the notification message. For example, the method includes the following steps:
步骤701，当SMF检测到PCF之前向SMF订阅的第一事件发生时，SMF根据第一事件的标识信息确定指示信息。可选的，SMF根据第一事件的标识信息和第一终端的终端信息确定指示信息。Step 701: When the first event that the SMF subscribes to the SMF before the SMF detects the PCF, the SMF determines the indication information according to the identification information of the first event. Optionally, the SMF determines the indication information according to the identifier information of the first event and the terminal information of the first terminal.
例如，在会话管理策略更新流程之前，SMF可以在会话建立的过程中获得第一终端的终端信息。此外，在SMF发起通知之前，SMF知道上报的第一事件的标识信息。For example, before the session management policy update process, the SMF may obtain the terminal information of the first terminal during the session establishment process. In addition, the SMF knows the identification information of the first event reported before the SMF initiates the notification.
SMF确定指示信息的实现方式与PCF确定指示信息的实现方式类似，可参考图4中步骤401的描述，此处不再赘述。The implementation of the SMF determination indication information is similar to the implementation manner of the PCF determination indication information.

需要说明的是，即便PCF在步骤704中决定不更新第一终端的策略信息，PCF根据指示信息也需要向SMF反馈策略通知。该策略通知中可以不包含第一终端的策略信息。It should be noted that even if the PCF decides not to update the policy information of the first terminal in step 704, the PCF needs to feed back the policy notification to the SMF according to the indication information. The policy information of the first terminal may not be included in the policy notification.
步骤706，SMF向PCF返回Npcf_SMPolicyControl_UpdateNotify响应。In step 706, the SMF returns an Npcf_SMPolicyControl_UpdateNotify response to the PCF.
步骤707，SMF根据指示信息，直到从PCF接收第一终端的策略信息，才执行与第一终端关联的后续操作。Step 707: The SMF performs the subsequent operation associated with the first terminal according to the indication information until the policy information of the first terminal is received from the PCF.
需要说明的一点是，对于本实施例而言，步骤707另外一种可能的实现方式，SMF根据指示信息，直到从PCF接收策略通知，即步骤705，才执行与第一终端关联的后续操作。It should be noted that, for the present embodiment, in another possible implementation manner of step 707, the SMF performs the subsequent operation associated with the first terminal according to the indication information until the policy notification is received from the PCF, that is, step 705.
步骤707可参考图4中步骤405的描述，此处不再赘述。Step 707 can refer to the description of step 405 in FIG. 4, and details are not described herein again.
需要说明的是，本申请并不限定步骤706和707之间的执行顺序，SMF可以先执行步骤706后执行步骤707，或先执行步骤707后执行步骤706，或同时执行步骤706和707。It should be noted that the present application does not limit the execution sequence between steps 706 and 707. The SMF may perform step 706 after performing step 706 first, or perform step 706 after performing step 707 first, or perform steps 706 and 707 at the same time.
因此，采用图7所示的方案，会话管理功能网元可根据事件的标识信息进行判断：对某特定的事件生成指示信息并发送至策略控制功能网元，使得策略控制功能网元无论是否更新策略都向会话管理功能网元发送策略，会话管理功能网元根据指示信息需要要等待至收到策略控制功能网元发送的策略之后才执行后续操作。否则，不生成指示信息，使得会话管理功能网元无需等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可执行后续操作。由此，提高了控制面网元的处理信令效率，进而提高了用户体验。Therefore, using the solution shown in FIG. 7, the session management function network element can determine according to the identification information of the event: generating indication information for a specific event and sending the information to the policy control function network element, so that the policy control function network element is updated whether or not The policy sends a policy to the session management function network element. The session management function network element needs to wait until the policy sent by the policy control function network element is received according to the indication information. Otherwise, the indication information is not generated, so that the session management function network element does not need to wait for the policy sent by the policy control function network element, and the subsequent operation can be performed after the first event is received and the notification response is received. Thereby, the processing signaling efficiency of the control plane network element is improved, thereby improving the user experience.
类似的，在策略关联修改流程中，可由移动性管理功能网元确定指示信息，通过通知消息向策略控制功能网元发送指示信息。也就是说，图7的流程同样适用于移动性管理功能网元(AMF)，区别在于服务相关的网元为AMF且对应AMF提供的服务，此处不再赘述。Similarly, in the policy association modification process, the indication information may be determined by the mobility management function network element, and the indication information is sent to the policy control function network element by using the notification message. That is to say, the flow of FIG. 7 is also applicable to the mobility management function network element (AMF). The difference is that the service-related network element is AMF and corresponds to the service provided by the AMF, and details are not described herein again.

由此，策略控制功能网元可根据事件的标识信息进行判断：对某特定的事件生成指示信息并发送至控制面网元，使得控制面网元收到指示信息后需要要等待至收到策 略控制功能网元发送的策略之后才执行后续操作。对于其他特定的事件可以不生成指示信息，使得控制面网元无需等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可执行后续操作。由此，提高了控制面网元的处理信令效率，进而提高了用户体验。Therefore, the network element of the policy control function can be determined according to the identifier information of the event: generating the indication information for a specific event and sending the indication information to the control plane network element, so that the control plane network element needs to wait until receiving the policy after receiving the indication information. The subsequent operations are performed after the policy sent by the function network element is controlled. The indication information may not be generated for other specific events, so that the control plane network element does not need to wait for the policy sent by the policy control function network element, and may perform subsequent operations after reporting the first event receipt notification response. Thereby, the processing signaling efficiency of the control plane network element is improved, thereby improving the user experience.

For example, the indication information is associated with identification information of the first event.
由此，对于某特定的事件，控制面网元收到指示信息后需要要等待至收到策略控制功能网元发送的策略之后才执行后续操作。否则，控制面网元可以不等待策略控制功能网元发送的策略，在上报第一事件收到通知响应后即可执行后续操作。由此，提高了控制面网元的处理信令效率，进而提高了用户体验。Therefore, for a specific event, after receiving the indication information, the control plane network element needs to wait until the policy sent by the policy control function network element is received, and then perform subsequent operations. Otherwise, the control plane network element may not wait for the policy sent by the policy control function network element, and may perform subsequent operations after reporting the first event to receive the notification response. Thereby, the processing signaling efficiency of the control plane network element is improved, thereby improving the user experience.
