In other words, this method can be executed by software or hardware installed in the first network function. The method includes the following steps.

[0040] S202: The first network function receives the first information sent by the second network function, where the first information is used to indicate at least one of the following: the network energy consumption quota subscribed by the terminal, the network energy consumption, and the network energy used.

[0070] In one embodiment, the method further includes: when the user spending limit changes, the first network function triggers the second network function to update the user spending limit, and specific details can be seen in Embodiment 5 hereinafter.

[0071] To describe in detail the method for controlling the terminal policy provided in the embodiments of the present application, several specific embodiments will be described below.

[0072] Embodiment 1

[0073] This embodiment mainly introduces the establishment and update of the association of the UE policy, as Figure 3 shown, this embodiment includes the following steps:

[0074] Step 1: When the AMF receives a UE policy container from the UE, the AMF establishes a UE policy association with the (V-)PCF. If the UE policy container from the UE is not received, the AMF may establish or update the UE policy association with the PCF based on the AMF local configuration.

[0075] Step 2: The AMF sends an Npcf_UEPolicyControl create / update request containing the following information: SUPI, which may include access type and RAT, PEI, ULI, UE time zone, serving network (PLMNID, or PLMN ID and NID,), list of internal-group-ID, and UE policy container (stored psi list, operating system identifier, indicating that the UE supports ANDSP, indicating that the UE is capable of reporting URSP rule enforcement to the network), UE policy ID, user-subscribed application service information, such as APP ID, Service ID, S-NSSAI, DNAI, DNN, etc.

[0076] Step 3: Note that steps 3 - 7 are optional. If the PCF has subscribed to the chf's spending limit control service, steps 3 - 7 can be skipped.

[0077] Based on the subscription of the UE subscriber, if the decision of the ue policy for the subscribed user by the PCF needs to be made according to the status of the EE counter, the PCF triggers the reporting / retrieval of the spending limit of the CHF.

[0078] Here, there may be one or more policy counters (policy counters) for the energy consumption credit limit of the UE: (Note that each counter has a corresponding identifier, and the pcf may send this identifier to the CHF in step 4). The policy counter is used for at least one of the following:

[0079] 1) Whether the network energy or network energy consumption used by the terminal or application service has reached or is about to reach the network energy consumption quota subscribed by the terminal.

[0080] 2) Whether the network energy consumption is greater than or equal to a first threshold. For example, determine whether the daily or monthly network energy consumption value is greater than or equal to the first threshold, and the unit of the first threshold can be J.

[0081] 3) Whether the relevant measurement value of network energy consumption is greater than or equal to the second threshold. For example, determine whether the relevant measurement value (such as overhead, call charges, etc.) of the daily or monthly network energy consumption value is greater than or equal to the second threshold. The unit of the second threshold can be yuan, US dollars, etc.

[0082] 4) Whether the current Energy Efficiency (EE) is greater than or less than the third threshold.

[0083] 5) The billing area / scope information.

[0084] Step 4: The PCF sends an Nchf_SpendingLimitControl_Subscribe request to the CHF, carrying one or more of the following: the identifier of the subscribed user, such as SUPI, the event identifier EventId "policy counter statuschange", the list of policy counter identifier(s), the Notification Target Address, Event Reporting Information (continuous reporting), such as periodic reporting, continuous reporting, single reporting, etc. The application service information subscribed by the user, such as APP ID, Service ID, S-NSSAI, DNAI, DNN, etc. If this information is provided, it is required that the CHF perform corresponding policy counter control for the granularity of the app application.

[0085] Step 5: The CHF responds to the Nchf_SpendingLimitControl_Subscribe service operation.

[0086] Step 6: When the CHF detects a change in the status of the EE policy counter, or the CHF may detect that the status of the EE policy counter will change at a certain future time point and decides to instruct the PCF to apply one or more pending statuses for the requested policy counter. For example, when the current CHF finds that the EE of the current Subscriber is about to reach the value subscribed by the user or the limited threshold, the CHF will instruct the PCF that at a certain future time, the PCF counter for this UE will change.

[0087] The CHF sends Nchf_SpendingLimitControl_Notify with the SUPI, notifying the target address and the status of the policy counter and the optional pending policy counter status and its activation time in the event information, if the PCF counter id was informed during PCF subscription. If the PCF counter ID was not informed, the CHF sends one or more pending states for any subscribed policy counters and the time by which they must be applied.

[0088] Step 7: The PCF acknowledges the Nchf_SpendingLimitControl_Notify response and considers this information as an input for policy decision-making.

[0089] Step 8: The PCF sends an Npcf_UEPolicyControl create response to the AMF. In this step, the PCF can directly send the new policy to the AMF. In this embodiment, the new policy may be an updated URSP of the terminal. For example, when the user's EE exceeds a certain credit limit, an application subscribed to by the terminal using the general S-NSSAI service is used instead of the original customized S-NSSAI; or the DNN of the service is modified, etc.

[0090] Step 9: The AMF performs UE configuration update, UE configuration update, and sends the latest UE policy

[0091] Note: In this embodiment and subsequent related embodiments, the CHF can also be an EE NF / NWDAF / OAM or other core network NF, and the service provided may not be the spending limit control service, but all can monitor the usage of the terminal's credit limit and inform the PCF to perform relevant operations.

[0092] Embodiment 2

[0093] This embodiment mainly introduces the terminal UE policy update triggered by the PCF through transparent UE policy delivery (based on the spending limit information of the CHF), as Figure 4 shown. This embodiment includes the following steps:

[0094] Steps 1 - 5 are the same as steps 3 - 7 of Embodiment 1.

[0095] Step 6: The PCF decides to update the UE Policy, triggering the UE configuration Update process to update the UE policy of the terminal. Based on the subscribed EE credit limit of the user / based on the spending limit information of the CHF (here, add a triggering condition that did not exist in the original process. Because of the CHF spending limit notification, the PCF updates the UE policy, or the triggering condition is to add a new network-triggered UE policy update case: the credit limit of the subscribed user UE reaches / the spending limit of the CHF changes, and the PCF modifies the URSP of the terminal. For example, when the user uses more EE than a certain credit limit, use the general S-NSSAI service for the applications subscribed by the terminal, instead of the original customized S-NSSAI; or modify the serving DNN).

[0096] Steps 6a and later are the update steps for UE configuration:

[0097] 6a. If the PCF has not subscribed to the AMF's notification of the UE's response to the UE policy information update, the PCF subscribes to the AMF to obtain the notification of the UE's response to the UE policy information update.

[0098] Step 7: The PCF invokes the Namf_Communication_N1N2MessageTransfer service operation provided by the AMF. The message includes the SUPI and the UE policy container.

[0099] Step 8: If the terminal is registered and accessible by the AMF in 3GPP access or non-3GPP access, the AMF shall transparently transfer the UE Policy container to the terminal through the registered and accessible access.

[0100] If the terminal is registered in both 3GPP and non-3GPP access and is accessible in both accesses and is served by the same AMF, the AMF transparently transfers the UE Policy container to the terminal through one of the access methods according to the AMF local policy.

[0101] If the AMF cannot reach the terminal through 3GPP access and non-3GPP access greater than or equal to, the AMF shall report to the PCF that it is unable to deliver the UE policy container to the terminal using Namf_Communication_N1N2TransferFailureNotification.

[0102] Step 9: If the terminal is in the CM-CONNECTED state through 3GPP access or non-3GPP access, the AMF transparently transmits the UE Policy Container (UE policy information) received from the PCF to the terminal.

[0103] Step 10: The terminal updates the terminal policy provided by the PCF and sends the result to the AMF.

[0104] Step 11: The AMF forwards the UE's response to the PCF using Namf_Communication_N1MessageNotify.

[0105] Embodiment III

[0106] This embodiment mainly introduces the modification of the terminal UE policy association triggered by the PCF. As Figure 5 shown, this embodiment includes the following steps:

[0107] Steps 1-5 are the same as steps 3-7 of Embodiment I.

[0108] Step 6: The PCF generates a new policy based on the information of the CHF and decides to update the URSP.

[0109] Step 7: The PCF calls the Npcf_UEPolicyControl_UpdateNotify service and carries the latest UE policy in the request.

[0110] Step 8: The AMF responds.

[0111] Step 9: The AMF triggers a UE configuration update to update the UE policy.

[0112] Embodiment IV

[0113] This embodiment mainly introduces the CHF obtaining the spending limit information of the EE. As Figure 6 shown, this embodiment includes the following steps:

[0114] Step 1: The CHF sends a query request to the PCF. The query request should include the user identifier (such as IMSI or SUCI) and the service identifier (such as service type, package type, etc.) so that the PCF can correctly identify the user and the service.

[0115] Step 2: After receiving the query request, the PCF first performs identity authentication and permission verification to ensure the legality and security of the request. If the authentication and verification are passed, the PCF queries the spending limit information of the user from its own database.

[0116] Step 3: After the PCF queries the user's consumption limit information, it encapsulates it into a response message and sends it to the CHF. The response message should contain the user's consumption limit information, such as the consumption limit value, consumption limit type, etc.

[0117] The message includes one or more of the following:

[0118] 1) The identifier of the policy counter, where the first information is determined by the policy counter.

[0119] 2) An indication that the user expenditure limit type is energy consumption.

[0120] 3) The network energy consumption quota subscribed by the terminal. For example, the daily / monthly network energy consumption is greater than or equal to XX nJ; the daily / monthly network energy consumption cost / phone bill is greater than or equal to XXX yuan / dollar; the current energy efficiency EE is greater than or less than a certain threshold (the CHF may charge according to EE, higher rate for higher EE and lower rate for lower EE), and the charging rates for different energy consumption efficiencies are different.

[0121] 4) Application service information: APP ID, S-NSSAI, DNAI, DNN, etc., which may not be provided. When not provided, it means that energy consumption control is performed for all services of a single user.

[0122] 5) Pending information. For example, it indicates that when the energy consumption reaches 90% of the subscription, a report is executed.

[0123] Step 4: After the CHF receives the response message, it parses the consumption limit information therein and performs billing and control according to the consumption situation. If the user has exceeded the consumption limit, the CHF can send a control message to the PCF to request it to restrict or control the user.

[0124] Example 5

[0125] This example mainly introduces the PCF to update the PCF counter information of the CHF, such as Figure 7 As shown, this example includes the following steps:

[0126] Step 1: When the user's energy consumption reaches the credit limit, the PCF may interact with the AS to obtain new PCF counter information. When reaching the credit limit, the user subscribes to a new package again, and the requirements related to the PCF counter change. The PCF triggers the CHF to update.

[0127] Step 2: The CHF receives the new PCF counter and executes new billing control.

[0128] Step 3: Update the response.

[0129] It should be noted that Example 4 and Example 5 can be implemented in combination with Example 1, Example 2, Example 3 or Example 6.

[0130] Example 6

[0131] This example mainly introduces the PCF triggering AMF relocation. As Figure 8 shown, this example includes the following steps:

[0132] Step 0: Under the conditions of registration, AM policy association or AMF triggering, the AMF requests the PCF to update the policy. Or the AMF subscribes to the PCF's policy update service, and when the PCF decides on a new policy, it updates it to the AMF (after subscribing to the request, the PCF returns a subscription response).

[0133] Steps 1-5 can refer to Steps 1-5 of Example 3.

[0134] Step 6: The PCF decides on a new policy.

[0135] Step 7: The PCF informs / sends the new policy to the AMF.

[0136] The Policy content includes but is not limited to the AMF relocation policy, informing the AMF to reselect the current UE to a new network slice S-NSSAI. For example, the new network slice is a default slice, and after the credit limit is exhausted, the user will access the default slice, and the network provides basic services; informing the AMF to reselect to another AMF or AMF set; modifying the service area (corresponding to TA) of the current registered slice, that is, when the credit limit reaches the user's subscribed upper limit, it is possible to modify the service scope of the S-NSSAI. For example, the current slice can only be used in a fixed area, and the user cannot access in other areas (saving energy consumption in other areas).

[0137] Step 8: The AMF performs related operations, such as AMF relocation.
