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

[0042] S202: The first network function receives first information sent by the second network function, where the first information is used for at least one of the following: a network energy consumption quota subscribed by the terminal, network energy consumption, and used network energy.

[0043] In each embodiment of the present application, the first network function and the second network function may be network functions (NF) of the core network.

Generally, network energy consumption may refer to the network energy consumption value per unit time, in units of J / s; used network energy (Energy Consumption, EC) may refer to the current total network energy consumption value, in units of J.

[0045] In one embodiment, the network energy consumption quota contracted by the terminal can also be referred to as the energy credit limit contracted by the terminal. In addition, the network energy consumption quota can also include the carbon (CO2) emissions of the terminal service, or the amount or ratio of new energy usage.

[0046] In one embodiment, the first information can be used to directly indicate the network energy consumption quota contracted by the terminal, the network energy consumption or the network energy used, and can also be used to indicate the following information: the network energy or network energy consumption used by the terminal or application service reaches or is about to reach the network energy consumption quota contracted by the terminal; the network energy consumption is greater than or equal to the first threshold, etc.

[0047] S204: The first network function performs a first operation based on the first information, where the first operation is related to the session policy.

[0048] In a session policy control method provided in an embodiment of the present application, a first network function receives first information sent by a second network function, where the first information is used to indicate at least one of the following: a network energy consumption quota contracted by a terminal, network energy consumption, and used network energy. The first network function performs a first operation based on the first information, thereby enabling session control based on the network energy consumption of the terminal, which is beneficial to energy saving in the communication system.

[0049] The terminal control method provided in the embodiments of the present application can modify the session policy or perform other operations such as reordering services through the service platform when the network energy used or consumed by the terminal or application service reaches or is about to reach the network energy consumption quota contracted by the terminal. Simultaneously, the second network function can also synchronously update the corresponding network billing policy and operation based on the user's operation.

[0050] In one embodiment, the first network function performing the first operation based on the first information includes at least one of the following:

[0051] 1) The first network function generates a session policy based on the first information.

[0052] 2) The first network function sends a first message to a third network function, which may be an application function (AF), etc. The first message includes the first information.

[0054] In one embodiment, the updated QoS information includes at least one of a QoS reference value and an independent QoS parameter.

[0055] In one embodiment, the method further includes: the first network function requests the second network function to update a policy counter based on the second message. The function of the policy counter will be described later.

[0056] Based on any of the above embodiments, before the first network function receives the first information sent by the second network function, the method further includes: the first network function sends a request message to the second network function, where the request message is used to trigger the second network function to report the first information.

The event includes a change in the state of a policy counter.

[0060] Based on any of the above embodiments, the second network function includes one or more policy counters, and the policy counter corresponding to the policy counter identifier received by the second network function is used to determine at least one of the following:

[0061] 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 contracted by the terminal.

[0062] 2) Whether the network energy consumption is greater than or equal to a first threshold, for example, determining whether the daily or monthly network energy consumption value is greater than or equal to the first threshold, where the unit of the first threshold may be J.

[0063] 3) Whether the relevant measurement value of network energy consumption is greater than or equal to the second threshold, for example, determining whether the relevant measurement value of daily or monthly network energy consumption value (such as expenses, call charges, etc.) is greater than or equal to the second threshold. The unit of the second threshold can be yuan, US dollars, etc.

[0064] 4) Whether the current energy efficiency (EE) is greater than or less than a third threshold.

[0065] Based on any of the above embodiments, the method also includes at least one of the following: the first network function receives a third message from the second network function; the first network function determines a user spending limit; the first network function sends a fourth message to the second network function, and the fourth message includes the user spending limit.

[0066] Typically, the user spending limit is used for billing the second network function; the network credit limit may be a description limit of some services signed by the user. Optionally, the user spending limit is the network credit limit signed by the terminal.

[0067] In one embodiment, the third message includes a user identifier and a service identifier, and the first network function determining the user spending limit includes: the first network function determining the user spending limit corresponding to the user identifier and the service identifier.

[0068] In one embodiment, the fourth message includes at least one of the following:

[0069] 1) An identifier of a policy counter, wherein the first information is determined by the policy counter.

[0070] 2) The user's expenditure limit type is an indication of energy consumption.

[0071] 3) Second information, the second information is used to indicate the granularity of statistics or reporting of the first information. The second information may be application service information subscribed by the user.

[0072] 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. For details, please refer to Example 6 below.

[0073] To illustrate the session policy control method provided in the embodiments of the present application in detail, several specific embodiments will be described below.

[0074] Example 1

[0075] This embodiment mainly introduces the PCF's own decision to update the SM policy. As shown in Figure 3, this embodiment includes the following steps:

[0076] Step 1: Based on the UE subscriber's subscription, the PCF decides the SM policy of the subscriber. The decision needs to be made based on the status of the EE counter, so the PCF triggers the reporting / acquisition of the CHF spending limit.

[0077] Here, there may be one or more policy counters for the UE's energy credit limit: (Note that each counter has a corresponding identifier, which the PCF may send to the CHF in step 4). The policy counter is used for at least one of the following:

[0078] 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 contracted by the terminal.

[0079] 2) Whether the network energy consumption is greater than or equal to a first threshold, for example, determining whether the daily or monthly network energy consumption value is greater than or equal to the first threshold, where the unit of the first threshold may be J.

[0080] 3) Whether the relevant measurement value of network energy consumption is greater than or equal to the second threshold, for example, determining whether the relevant measurement value of daily or monthly network energy consumption value (such as expenses, call charges, etc.) is greater than or equal to the second threshold. The unit of the second threshold can be yuan, US dollars, etc.

[0081] 4) Whether the current energy efficiency (EE) is greater than or less than a third threshold.

[0082] 5) Billing area / scope information.

[0083] Step 2: The PCF sends an Nchf_SpendingLimitControl_Subscribe request to the CHF, carrying one or more of the following: the subscriber's identifier, such as SUPI, the event identifier EventId "policy counter status change", 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., and the user's subscribed application service information, such as APP ID, Service ID, S-NSSAI, DNAI, DNN, etc. If this information is provided, the CHF is required to perform corresponding policy counter control for the granularity of the app application.

[0084] Step 3: CHF responds to the Nchf_SpendingLimitControl_Subscribe service operation

[0085] Step 4: When the CHF detects that the state of the EE policy counter has changed, or the CHF may detect that the state of the EE policy counter will change at a certain point in the future, it decides to instruct the PCF to apply one or more pending states to the requested policy counter. For example, when the CHF finds that the EE of the current user Subscriber is about to reach the user's contracted value or a specified threshold, the CHF will instruct the PCF that the PCF counter for this UE will change at a certain time in the future.

[0086] The CHF sends Nchf_SpendingLimitControl_Notify with SUPI, notifying the destination address and the policy counter status in the event information and the optional pending policy counter status and its activation time, if the PCF counter ID was notified during subscription. If the PCF counter ID was not informed, the CHF sends one or more pending statuses for any subscribed policy counters and the time when they must be applied.

[0087] Step 5: The PCF confirms sending the Nchf_SpendingLimitControl_Notify response and considers this information as input for policy decision.

[0088] Step 6: PCF determines the update session policy.

[0089] Step 7: PCF sends a Npcf_UEPolicyControl create response to SMF. In this step, PCF can directly send the new policy to SMF. In this embodiment, the new policy may be the updated QoS parameters.

[0090] Step 8: SMF responds.

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

[0092] Example 2

[0093] This embodiment mainly introduces that the PCF interacts with the AF to notify the AF of the credit limit being reached, and the PCF itself generates a policy. As shown in Figure 4, this embodiment includes the following steps:

[0094] Step 1: AF signs up for NEF's eventexposure service and can provide at least one of the following information:

[0095] 1)Event ID: Energy Credit Limit Control.

[0096] 2) Provide user ID (GPSI ID, etc.) or group user ID (external group ID, etc.).

[0097] 3) The total energy consumption quota value per user / per service (i.e., the energy quota value that has been signed and can be used, refer to the relevant parameters in Example 1 for details).

[0098] 4) Recommended QoS values, such as QoS parameters when consumption exceeds the quota value and QoS parameters when it does not exceed the quota value. QoS parameters can be in the form of QoS reference or individual QoS parameter

[0099] 5)AF ID.

[0100] 6) APP ID or Flow ID is used to identify the controlled service.

[0101] Step 2: NEF performs authentication. If it passes, NEF subscribes to PCF's eventexposure service and passes AF's relevant information to PCF.

[0102] Step 3: The PCF determines that the policy control for the energy credit limit requires the CHF to implement the spending limit control.

[0103] Alternatively, depending on the PCF configuration, the Energy Credit limit policy control requires CHF execution, and then the CHF service contract is initiated.

[0104] For steps 3-4, please refer to the corresponding steps in Example 1.

[0105] Optionally, steps 3-4 may not be performed here, but the PCF has already signed a spending limit control service of CHF.

[0106] Step 4: Same as in Example 1. If there are any differences from Example 1, the policy counter related content in Example 1 is provided by the PCF.

[0107] Here, it is possible that the counter-related content is also provided by the AF, that is, the related content in step 1, which the PCF needs to send to the CHF together.

[0108] Step 5: Sign the response.

[0109] Step 6: Sign the response.

[0110] Step 7: See Example 1.

[0111] Step 8-1: Same as in Example 1.

[0112] In step 8-2, the PCF informs the AF that the energy consumption of a specific user or a specific group of users for a specific service or all services exceeds the contracted credit limit.

[0113] Steps 9-11 are the same as steps 6-8 of the first embodiment. According to the internal policy of the PCF or the relevant information transmitted by the AF, the PCF sets a new SM policy, such as using a new QoS value for a specific user and / or a specific service and / or a specific session.

[0114] Example 3

[0115] This embodiment mainly introduces that the PCF interacts with the AF to inform the AF that the credit limit has been reached, and the AF generates a policy to update the QoS. As shown in Figure 5, this embodiment includes the following steps:

[0116] The difference from the second embodiment is that the PCF policy is determined and input by the AF in step 9. The AF informs the network of the latest QoS modification by using the NEF_AfsessionWithQoSUpdate service, notifying the network of the new QoS reference or individual QoS parameter and making the modification.

[0117] Optionally, the AF may also modify the billing area / scope related to terminal billing in the PCF.

[0118] Example 4

[0119] This embodiment mainly introduces that the PCF interacts with the AF to inform the AF that the credit limit has been reached, and the AF generates a policy. The QoS remains unchanged, but the PCF counter is updated. The steps included in this embodiment are shown in Figure 6.

[0120] The difference from Example 3 is that AF does not perform a credit limit operation by reducing QoS as in the related operations of Example 3, but instead signs a new credit limit with the operator offline, and informs PCF and CHF to update the new pcf counter through steps 10-14 (refer to the business scenario where the user can order a new traffic package after the traffic package is used up).

[0121] This embodiment five

[0122] This embodiment mainly introduces how CHF obtains EE spending limit information. As shown in FIG7 , this embodiment includes the following steps:

[0123] 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 service identifier (such as service type, package type, etc.) so that the PCF can correctly identify the user and service.

[0124] Step 2: After receiving the query request, PCF first performs identity authentication and permission verification to ensure the legitimacy and security of the request. If the authentication and verification pass, PCF will query the user's spending limit information from its own database.

[0125] Step 3: After the PCF obtains the user's spending limit information, it encapsulates it into a response message and sends it to the CHF. The response message should include the user's spending limit information, such as the spending limit value and spending limit type.

[0126] The message includes but is not limited to one or more of the following:

[0127] 1) An identifier of a policy counter, wherein the first information is determined by the policy counter.

[0128] 2) The user's expenditure limit type is an indication of energy consumption.

[0129] 3) The network energy consumption quota contracted 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 expenses / call charges are greater than or equal to XXX dollars; the current energy efficiency (EE) is greater than or less than a certain threshold (CHF may be billed based on EE, with higher EE rates and lower EE rates). Different energy efficiency rates are charged at different rates.

[0130] 4) Application service information: APP ID, S-NSSAI, DNAI, DNN, etc., which may not be provided. If not provided, it indicates that energy consumption control is performed on all services of a single user.

[0131] 5) Pending information, for example, indicating that when the energy consumption reaches 90% of the contracted amount, reporting is performed.

[0132] Step 4: After receiving the response message, CHF analyzes the consumption limit information and performs billing and control based on the consumption situation. If the user has exceeded the consumption limit, CHF can send a control message to PCF to request it to limit or control the user.

[0133] Example 6

[0134] This embodiment mainly introduces the PCF updating the PCF counter information of the CHF. As shown in FIG8 , this embodiment includes the following steps:
