The first network function performs a first operation based on the first information, and then can control the session based on the network energy consumption of the terminal, which is beneficial to energy saving of the communication system.

[0047] In the terminal control method provided by the embodiment of the present application, when 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 subscribed by the terminal, the session policy can be modified, or operations such as re-subscribing to services can be performed through the service platform. At the same time, the second network function can also synchronously update the corresponding network charging policy and operations according to the user's operations.

[0060] 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, and the unit of the first threshold can be J.

[0061] 3) Whether the relevant measurement value of the network energy consumption is greater than or equal to a second threshold, for example, determining 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, and the unit of the second threshold can be yuan, US dollars, etc.

[0062] 4) Whether the current energy efficiency (EE) is greater than or less than a third threshold.

[0064] Generally, the user spending limit is used for charging the second network function; the network energy consumption quota may be some service description restrictions subscribed by the user. Optionally, the user spending limit is the network energy consumption quota subscribed by the terminal.

[0065] In one embodiment, the third message includes a user identifier and a service identifier, and the first network function determines the user spending limit as follows: the first network function determines the user spending limit corresponding to the user identifier and the service identifier.

[0066] In one embodiment, the fourth message includes at least one of the following:

[0067] 1) The identifier of a policy counter, where the first information is determined by the policy counter.

[0068] 2) An indication that the user spending limit type is energy consumption.

[0069] 3) Second information, which is used to: indicate the granularity of the statistics or reporting of the first information, and the second information may be the application service information subscribed by the user.

[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. For details, refer to Embodiment 6 later.

[0071] To illustrate the session policy control method provided by the embodiments of the present application in detail, several specific embodiments will be described below.

[0072] Embodiment 1

[0073] This embodiment mainly introduces the PCF's own decision to update the SM policy. As Figure 3 shown, this embodiment includes the following steps:

[0074] Step 1: According to the subscription of the UE subscriber, if the PCF decides that the decision of the SM policy of the subscribed user needs to be based on the status of the EE counter, the PCF triggers the reporting / obtaining of the spending limit of the CHF.

[0075] Here, there may be one or more 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 the fourth step). The policy counter is used for at least one of the following:

[0076] 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.

[0077] 2) Whether the network energy consumption is greater than or equal to the 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.

[0078] 3) Whether the relevant measurement value of the network energy consumption is greater than or equal to the second threshold. For example, determine whether the relevant measurement values (such as overhead, call charges, etc.) of the daily or monthly network energy consumption value are greater than or equal to the second threshold, and the unit of the second threshold can be yuan, US dollars, etc.

[0079] 4) Whether the current Energy Efficiency (EE) is greater than or less than the third threshold.

[0080] 5) The charging area / scope information.

[0081] Step 2: 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, the 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 the corresponding policy counter control for the granularity of the app application.

[0082] Step 3: The CHF responds to the Nchf_SpendingLimitControl_Subscribe service operation

[0083] Step 4: When the CHF detects that the status of the EE policy counter has changed, 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 states 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 defined threshold, the CHF will instruct the PCF that the PCF counter for this UE will change at a certain future time.

[0084] 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 when they must be applied.

[0085] Step 5: The PCF acknowledges the sending of the Nchf_SpendingLimitControl_Notify response and considers this information as an input for policy decision-making.

[0086] Step 6: The PCF determines to update the session policy.

[0087] Step 7: The PCF sends an Npcf_UEPolicyControl create response to the SMF. In this step, the PCF can directly send the new policy to the SMF. In this embodiment, the new policy may be updated QoS parameters

[0088] Step 8: The SMF responds.

[0089] Note: In this embodiment and subsequent related embodiments, the CHF can also be an EE NF / NWDAF / OAM or other core network NF, and may provide services other than the spending limit control service, but can monitor the usage of the terminal's credit limit and inform the PCF to perform relevant operations.

[0090] Embodiment 2

[0091] This embodiment mainly introduces that the PCF interacts with the AF to inform that the credit limit has been reached, and the PCF generates its own policies, such as Figure 4 As shown, this embodiment includes the following steps:

[0092] Step 1: The AF subscribes to the event exposure service of the NEF and can provide at least one of the following information:

[0093] 1) Event ID: Energy Credit Limit Control.

[0094] 2) Provide the user ID (GPSI ID, etc.) or the Group user ID (external group ID, etc.).

[0095] 3) Total energy consumption quota value per user / per service (i.e., the energy quota value that has been contracted and can be used, specifically refer to the relevant parameters in Embodiment 1).

[0096] 4) Suggested QoS value, such as QoS parameters when consumption exceeds the quota value and when it does not exceed, and the form of QoS parameters can be QoS reference or individual QoS parameter

[0097] 5) AF ID.

[0098] 6) APP ID or Flow ID is used to identify the controlled service.

[0099] Step 2: The NEF performs authentication. If passed, the NEF subscribes to the event exposure service of the PCF and transfers the relevant information of the AF to the PCF.

[0100] Step 3: The PCF determines that for the policy control of Energy credit limit, the CHF needs to perform the control of spending limit.

[0101] Or, according to the PCF configuration, the policy control of Energy Credit limit needs to be performed by the CHF, and then the subscription of the CHF service is initiated.

[0102] Steps 3 - 4 can refer to the corresponding steps in Embodiment 1.

[0103] Optionally, Steps 3 - 4 can be not executed here, but the PCF has already subscribed to the spending limit control service of the CHF.

[0104] Step 4: Similar to Embodiment 1. What may be different from Embodiment 1 is that the relevant content of the policy counter in Embodiment 1 is provided by the PCF.

[0105] Here, it is possible that the counter - related content is also provided by the AF, that is, the relevant content in Step 1, and the PCF needs to send it to the CHF together.

[0106] Step 5: Subscription response.

[0107] Step 6: Subscription response.

[0108] Step 7: Refer to Embodiment 1.

[0109] Step 8 - 1: Similar to Embodiment 1.

[0110] Step 8-2, the PCF notifies the AF that the energy consumption of a specific user or a group of users for a specific service or all services exceeds the subscribed credit limit.

[0111] Steps 9-11 are the same as 6-8 in Embodiment 1. According to the policy within 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.

[0112] Embodiment 3

[0113] This embodiment mainly introduces that the PCF interacts with the AF to notify that the credit limit has been reached, and the AF generates a policy to update the QoS, as Figure 5 shown. This embodiment includes the following steps:

[0114] Different from Embodiment 2, the policy of the PCF is determined and input by the AF in Step 9. The AF notifies the network of the latest QoS modification by using the NEF_AfsessionWithQoSUpdate service, and notifies the network of the new QoS reference or individual QoS parameter for modification.

[0115] Optionally, the AF can also modify the charging area / scope related to terminal charging in the PCF.

[0116] Embodiment 4

[0117] This embodiment mainly introduces that the PCF interacts with the AF to notify that the credit limit has been reached, and the AF generates a policy with the QoS unchanged, but updates the PCF counter. The steps included in this embodiment are as Figure 6 shown.

[0118] Different from Embodiment 3, the AF does not perform credit limit operations by reducing the QoS as in the relevant operations in Embodiment 3. Instead, for example, it signs a new credit limit with the operator offline and notifies the PCF and CHF to update the new pcf counter through Steps 10-14 (referring to the business scenario where after the user uses up the traffic package, they can order a new traffic package).

[0119] Embodiment 5

[0120] This embodiment mainly introduces that the CHF obtains the spending limit information of the EE, as Figure 7 shown. This embodiment includes the following steps:

[0121] Step 1: CHF sends a query request to PCF. The query request should include user identification (such as IMSI or SUCI) and service identification (such as service type, package type, etc.) so that PCF can correctly identify the user and the service.

[0122] Step 2: After receiving the query request, PCF first performs identity authentication and permission verification to ensure the legality and security of the request. If the authentication and verification are passed, PCF will query the spending limit information of the user from its own database.

[0123] Step 3: After querying the spending limit information of the user, PCF encapsulates it into a response message and sends it to CHF. The response message should include the user's spending limit information, such as the spending limit value, spending limit type, etc.

[0124] The message includes one or more of the following:

[0125] 1) The identifier of the policy counter, where the first information is determined by the policy counter.

[0126] 2) An indication that the user spending limit type is energy consumption.

[0127] 3) The network energy consumption quota subscribed by the terminal. For example, the network energy consumption per day / month is greater than or equal to XX nJ; the overhead / charge of the network energy consumption per day / month is greater than or equal to XXX yuan / dollar; the current energy efficiency EE is greater than or less than a certain threshold (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.

[0128] 4) Application service information: APP ID, S-NSSAI, DNAI, DNN, etc., which may also not be provided. When not provided, it means that energy consumption control is performed for all services of a single user.

[0129] 5) Pending information. For example, it indicates that a report is to be executed when the energy consumption reaches 90% of the subscription.

[0130] Step 4: After receiving the response message, CHF parses the spending limit information therein and performs charging and control according to the consumption situation. If the user has exceeded the spending limit, CHF can send a control message to PCF to request it to restrict or control the user.

[0131] Embodiment Six
