[0049] Next, with reference to the accompanying drawings, the terminal control method provided in the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0050] As Figure 2 shown, the embodiments of the present application provide a terminal control method 200. This method can be executed by a first network function. In other words, this method can be executed by software or hardware installed in the first network function. The method includes the following steps.

[0051] S202: The first network function obtains first information, 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.

[0052] In various embodiments of this application, the first network function may be a network function (NF) of the core network. For example, the first network function may be an Access and Mobility Management Function (AMF) or a Session Management Function (SMF), etc.

[0053] In one embodiment, the first network function may obtain the first information from one or more other network functions. For example, the first network function obtains the subscription information of the terminal from the Unified Data Management (UDM), and the subscription information of the terminal includes the network energy consumption quota subscribed by the terminal; for another example, the first network function obtains the network energy consumption or the network energy used from the Energy Efficiency Network Functions (EE NF), the Network Data Analytics Function (NWDAF), or the Operation Administration and Maintenance (OAM), etc.

[0054] In one embodiment, the network energy consumption or the network energy used may refer to the services subscribed by the terminal (which may be a single service, multiple services, or all services), the application service, or the network energy consumed by the current terminal. Generally, the network energy consumption may refer to the network energy consumption value per unit time, and the unit may be J / s; the network energy used (Energy Consumption, EC) may be the current total network energy consumption value, and the unit may be J.

[0055] In one embodiment, the network energy consumption quota subscribed by the terminal may also be referred to as the energy credit limit subscribed by the terminal. In addition, the network energy consumption quota may also include the carbon (CO2) emissions of the terminal service, or the new energy usage or the new energy usage ratio.

[0056] In one embodiment, the first information may be used to directly indicate the network energy consumption quota subscribed by the terminal, the network energy consumption, or the network energy used, and may also be used to indicate the following information: the network energy or network energy consumption used by the terminal or the application service reaches or is about to reach the network energy consumption quota subscribed by the terminal; the network energy consumption is greater than or equal to the first threshold, etc.

[0057] S204: The first network function performs a first operation based on the first information.

[0058] The first operation performed by the first network function may be an operation related to terminal control.

[0059] In the terminal control method provided by the embodiments of the present application, the first network function obtains first information, and 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, the network energy used. The first network function performs a first operation based on the first information, and thus can control the network energy consumption of the terminal, which is beneficial to energy saving of the communication system.

[0060] In the terminal control method provided by the embodiments of the present application, the subscription of the terminal reflects that the user subscribes to the control of the energy consumption quota or the network energy consumption quota that can be used. The first network function (such as AMF) can obtain the information for controlling the network energy consumption quota of the user (user granularity, slice granularity, app granularity) during the registration process and interact with the EE NF or other NF / OAM to control the network energy consumption of the terminal. The first network function (such as SMF) obtains the information for controlling the network energy consumption quota of the user (PDU session granularity, QoS flow granularity, app granularity) during the PDU session establishment process and interacts with the EE NF or other NF / OAM to control the network energy consumption of the terminal.

[0061] In one embodiment, the first network function performing the first operation based on the first information includes: when the first network function determines that a first condition is satisfied based on the first information, the first network function performs the first operation, and the first condition may include at least one of the following:

[0062] 1) 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.

[0063] 2) The network energy consumption is greater than or equal to a first threshold. For example, the network energy consumption value per day or per month is greater than or equal to the first threshold, and the unit of the first threshold may be J.

[0064] 3) The relevant measurement value of the network energy consumption is greater than or equal to a second threshold. For example, the relevant measurement value (such as overhead, call charge, etc.) of the network energy consumption value per day or per month is greater than or equal to the second threshold, and the unit of the second threshold may be yuan, US dollar, etc.

[0065] 4) The current energy efficiency (EE) is greater than or less than a third threshold, and this energy efficiency may be the network energy efficiency caused by the terminal service.

[0066] In one embodiment, the first operation performed by the first network function based on the first information includes at least one of the following:

[0067] 1) Reject the registration request of the terminal. For example, if the first network function is the AMF, during the registration process of the terminal, when the AMF determines based on the first information that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal, the AMF rejects the registration request of the terminal. For specific details, refer to Embodiment 1 hereinafter.

[0068] In this embodiment, the first network function may send a registration request rejection message to the terminal. The registration request rejection message includes a cause value, and the cause value is used to indicate the above first condition. For example, it indicates that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal.

[0069] 2) Initiate the deregistration process of the terminal. For example, if the first network function is the AMF, after the terminal is successfully registered, when the AMF determines based on the first information that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal, the AMF initiates the deregistration process of the terminal. For specific details, refer to Embodiment 1 hereinafter.

[0070] In this embodiment, the first network function may send a deregistration request message to the terminal. The deregistration request message includes a cause value, and the cause value is used to indicate the above first condition. For example, it indicates that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal.

[0071] 3) Reject the session establishment request of the terminal. For example, if the first network function is the SMF, during the session establishment process of the terminal, when the SMF determines based on the first information that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal, the SMF rejects the session establishment request of the terminal. For specific details, refer to Embodiment 2 hereinafter.

[0072] In this embodiment, the first network function may send a session establishment request rejection message to the terminal. The session establishment request rejection message includes a cause value, and the cause value is used to indicate the above first condition. For example, it indicates that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal.

[0073] 4) Initiate the session release process of the terminal. For example, if the first network function is the SMF, after the terminal session is successfully established, the SMF determines based on the first information that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal, then the SMF initiates the session release process of the terminal. For specific details, please refer to Embodiment 2 later.

[0074] In this embodiment, the first network function may send a session release request message to the terminal. The session release request message includes a cause value, and the cause value is used to indicate the above first condition. For example, it indicates that the network energy or network power consumption used by the terminal or the application service reaches or is about to reach the network power consumption quota subscribed by the terminal.

[0075] In one embodiment, the first network function performing the first operation based on the first information includes: the first network function sends a request message to the second network function. The second network function may be a Policy Control Function (PCF), and the request message is used for at least one of the following:

[0076] 1) Establishing, modifying, or updating an Access Management policy (AM policy).

[0077] 2) Establishing, modifying, or updating a User Equipment policy (UE policy).

[0078] 3) Establishing, modifying, or updating a Session Management policy (SM policy).

[0079] For specific details of this embodiment, please refer to Embodiment 3 or Embodiment 4 later.

[0080] In this embodiment, the second network function may generate policy information based on the above request message and may also send the policy information to the first network function.

[0086] 5) User Equipment policy establishment, modification, or update request message.

[0087] 6) Session management policy establishment, modification, or update request message.

[0088] Optionally, in one embodiment, the first network function performing the first operation based on the first information further includes: the first network function receiving a policy message from the second network function, where the policy message includes at least one of the following:

[0089] 1) The service scope (or service area) of the current user. For example, when the user reaches the energy consumption limit they subscribed to, the second network function (such as PCF) reduces the scope of services that the user can use, achieving an energy-saving effect.

[0090] 2) The updated UE Route Selection Policy (URSP) of the user. For example, among the original single network slice selection assistance information (S-NSSAI) and data network name (DNN) for the user to access a specific service network slice, when the user reaches the energy consumption limit they subscribed to, the user is selected to be switched to a default S-NSSAI or DNN.

[0131] 4) An indication of whether the terminal is in an energy saving state, for example, an indication that the terminal is in an energy saving state, or an indication that the terminal is in a no energy saving state.

[0132] The terminal's registration request carries information that can be carried in the Radio Resource Control (RRC) signaling with the Radio Access Network (RAN), or can be carried in the Non-Access Stratum (NAS) signaling and sent to the AMF.

[0133] Optionally, if the information carried in the terminal registration request is located in the RRC signaling, the RAN may perform AMF selection based on the information carried by the terminal.

[0134] a) If 5G-S-TMSI / GUAMI is not provided or provided but the corresponding AMF does not support network energy consumption quota control, which can also be called energy credit limit control, the RAN performs AMF selection and selects an AMF that supports credit limit control. Here, it can be selected that the RAN configures the capabilities of AMFs under different service areas / Tracking areas (for example, a list of AMFs that support and do not support credit control under different TAs).

[0135] b) If the RAN fails to select a suitable AMF, the RAN forwards the registration request to a pre-configured AMF (e.g., the default AMF). Then the AMF performs AMF selection to choose an AMF that supports credit limit control. Here, the AMF performs AMF reselection (AMF relocation). The default AMF can obtain the AMF set or AMF information (e.g., AMF set ID / address or AMF ID / address) that supports credit limit in the current service area / tracking area by accessing a specific core network function such as NSSF / EE NF, etc. The method of obtaining is that the AMF sends the information carried in the UE registration as above and / or the current TA information of the UE and / or credit control indication, etc. The NSSF / EE NF has the capabilities of AMFs in different service areas / tracking areas (e.g., the list of AMFs that support credit control and do not support credit control under different TAs). It selects a servable AMF based on the information provided by the AMF and feeds it back to the default AMF.

[0136] Step 2: The registration request is sent to the AMF with credit control capability.

[0137] Step 3: The AMF accesses the UDM (carrying the UE's request information in Step 1) to obtain the subscription information of the current terminal. The content of the subscription information is as follows, one or more of the following:

[0138] 1) The network energy consumption quota (such as credit limit) of the following granularities subscribed by the terminal: S-NSSAI, DNN, APP identifier. For example, S-NSSAI1, DNN1 or APP ID 1: credit limit 1; S-NSSAI1, DNN2 or APP ID 2: credit limit2;...

[0139] 2) The network energy consumption quota of each terminal granularity subscribed by the terminal.

[0140] 3) The start control time (start time) of the network energy consumption quota.

[0141] 4) The end control time (end time) of the network energy consumption quota.

[0142] 5) Control area information of the network energy consumption quota introduced above. For example, in some areas, it is included in the network energy consumption quota control, in some areas, it is not included in the network energy consumption quota control, or in all areas, it is included in the network energy consumption quota control.

[0143] Step 4: Optionally, the AMF requests the EE NF / NWDAF / OAM or some other NF to obtain the above energy consumption situation that the current terminal has used, and may carry the following information:

[0144] 1) The identifier of the terminal.

[0145] 2) S-NSSAI, DNN or APP identifier.

[0146] 3) Service area or Tracking area information.

[0147] 4) The starting calculation moment of the network energy used.

[0148] 5) The ending calculation moment of the network energy used.

[0149] 6) The network energy consumption quota subscribed by the terminal.

[0150] The EE NF / NWDAF / OAM returns the energy information that the current UE has used or an indication (currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.).

[0151] In this step, the AMF can also subscribe to the energy usage notification service of network functions such as the EE NF, that is, when the energy usage of the current UE exceeds the usage limit, notify the AMF of an indication (currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.) or regularly and cyclically return the energy information that the current UE has used to the AMF.

[0152] Step 5: If the energy quota that the current UE has used reaches the energy quota it has subscribed to, the AMF rejects the terminal's registration request and carries the cause value: credit limit reached (reaching the total energy subscribed by the user) in the message of the registration request rejection.

[0153] It should be noted that if the energy quota subscribed by the UE is at the per UE granularity, the process terminates at Step 5.

[0154] If the energy quota subscribed by the UE is for a certain type of service, such as a certain S-NSSAI, DNN, or APPID, the AMF rejects the registration request for the S-NSSAI corresponding to the service that reaches the total energy, but continues to execute the registration requests for other services or operations subscribed by the UE, that is, continues to execute the following steps.

[0155] Step 6: The AMF triggers credit limit control for the UE. It should be noted that this step can occur after the terminal registration, for example, actively triggered by the AMF.

[0156] Step 7: The AMF requests the network functions such as the EE NF to feedback the already used energy consumption value corresponding to the current UE. Or the AMF subscribes to the service of the network functions such as the EE NF to monitor the already used energy consumption value corresponding to the current UE [the information carried includes but is not limited to the subscription information in Step 4]. When the credit limit is exceeded, the EE NF will feedback the already used energy information of the current UE or an indication (currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.).

[0157] Here, there is a possibility that there is no credit limit value in the user's subscription, or there is another possibility that there is only the service information for executing the credit limit in the user's subscription, and the credit limit is stored in the corresponding network functions such as the EE NF. The EE NF controls according to the configured credit limit.

[0158] Step 8: If the already used energy quota of the current UE reaches its subscribed energy quota, the AMF initiates a deregistration process and carries a cause value in the deregistration request message: credit limit reached (reaching the total network energy subscribed by the user).

[0159] If the energy quota subscribed by the UE is at the per UE granularity, the process terminates, and the AMF initiates the deregistration of all registered S-NSSAIs of the terminal.

[0160] If the energy quota subscribed by the UE is for a certain type of service, such as a certain S-NSSAI, DNN, or APPID, the AMF only initiates a deregistration request for the S-NSSAI corresponding to the service that reaches the total energy, and the registration status of other S-NSSAIs remains unchanged.

[0161] In all embodiments of this application, the EE NF / NWDAF / OAM can also be other core networks such as the PCF and CHF.

[0162] As another implementation manner of Embodiment 1, as Figure 4 shown, optionally, the UDM may also not store the network energy consumption quota information (abbreviated as limit information), but the AMF directly interacts with the EE NF, etc. to obtain it, and the remaining processes are the same as those in Embodiment 1 above.

[0163] There are several possibilities in the above process:

[0164] The UE carries the indication information of Step 1, and the AMF actively triggers Step 4 to obtain the limit information upon receiving the indication.

[0165] The UE does not carry the indication, and the AMF actively triggers Step 4 to obtain the limit information.

[0166] The UE carries the indication and the subscribed credit limit, and the AMF only obtains the energy usage situation from Step 4, and the EE NF does not have the relevant information on the credit limit.

[0167] Embodiment 2

[0168] This embodiment mainly introduces the SMF access control. As Figure 5 shown, this embodiment includes the following steps:

[0169] Step 1: The UE initiates a PDU session establishment request. Optionally, it carries the relevant information as in Embodiment 1 to indicate that it has subscribed to the service of credit limit control.

[0170] Compared with Step 1 of Embodiment 1, its credit limit control may be more granular in terms of PDU session or QoS flow, and the information provided may also include at least one of the following:

[0171] 1) QoS reference and the network energy consumption quota of the QoS reference.

[0172] 2) Personal QoS parameters and the network energy consumption quota of the personal QoS parameters.

[0173] 3) APP identifier and the network energy consumption quota of the APP identifier.

[0174] Step 2: Optionally, when the AMF performs SMF selection, it may be based on the information carried by the UE and select an SMF with the ability of credit limit control.

[0175] Step 3: The AMF initiates a pdu session connection carrying the information requested by the UE.

[0176] Step 4: The SMF obtains the subscription information of the UDM, the same information obtained by the UDM in Embodiment 1, and in addition, more fine-grained information:

[0177] 1) QoS reference and the network energy consumption quota of the QoS reference.

[0178] 2) Personal QoS parameters and the network energy consumption quota of the personal QoS parameters.

[0179] 3) APP identifier and the network energy consumption quota of the APP identifier.

[0180] Step 5: The SMF requests the EE NF / NWDAF / OAM or some other NF to obtain the above energy consumption situation already used by the current UE, and may carry the following information:

[0181] 1) The identifier of the said terminal.

[0182] 2) S-NSSAI, DNN or APP identifier.

[0183] 3) Service area or Tracking area information.

[0184] 4) The starting calculation moment of the used network energy.

[0185] 5) The ending calculation moment of the used network energy.

[0186] 6) The network energy consumption quota subscribed by the said terminal.

[0187] The EE NF / NWDAF / OAM returns the energy information already used by the current UE or an indication (currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.).

[0188] In this step, the SMF can also subscribe to the energy usage notification service of network functions such as the EE NF, that is, when the energy usage of the current UE exceeds the usage limit, notify the SMF of an indication (currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.) or regularly and cyclically return the energy information already used by the current UE to the SMF.

[0189] Step 6: If the energy quota already used by the current UE reaches its subscribed energy quota, the SMF rejects the PDU session establishment request of the terminal and carries the cause value: credit limit reached (reaching the total energy subscribed by the user) in the request rejection message.

[0190] Step 7: Reject the request and feedback to the UE.

[0191] 7-0, if the upper limit of the credit limit is not reached, continue with the PDU session establishment.

[0192] Steps 8 to 9: The SMF requests network functions such as the EE NF to feedback the already used energy consumption value corresponding to the current UE, or the SMF subscribes to the service of the EE NF and other network functions to monitor the already used energy consumption value corresponding to the current UE. The information carried includes but is not limited to the content in the subscribed information. When the credit limit is exceeded, the EE NF will feedback the already used energy information of the current UE or an indication (such as currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.).

[0193] Here, there are two possibilities. One is that there is no credit limit value in the user's subscription, or another possibility is that there is only service information for implementing the credit limit in the user's subscription, and the credit limit is stored in corresponding network functions such as the EE NF. The EE NF controls according to the configured credit limit.

[0194] Step 10: If the already used energy quota of the current UE reaches its subscribed energy quota, the SMF initiates the PDU session release process and carries the cause value: credit limit reached (reaching the total energy subscribed by the user) in the feedback message.

[0195] As another implementation manner of Embodiment 2, as Figure 6 shown, optionally, the UDM may not store the limit information, but the SMF directly interacts with the EE NF and others to obtain it. The remaining processes are the same as those in Embodiment 1 above.

[0196] There are several possibilities in the above process:

[0197] The UE carries the indication information (indication) in Step 1, and the SMF actively triggers Step 5 to obtain the limit information upon receiving the indication

[0198] The UE does not carry any information such as indication, and the SMF actively triggers Step 5 to obtain the limit information

[0199] The UE carries an indication and a signed credit limit. The SMF only obtains the energy usage from step 5, and the EE NF does not have information related to the credit limit.

[0200] Embodiment 3

[0201] This embodiment mainly introduces AMF policy control, such as Figure 7 As shown, this embodiment includes the following steps:

[0202] The difference between this embodiment and Embodiment 1: Instead of simply controlling whether the terminal is registered, during the registration process or after the user registers, the AMF is allowed to modify / update the corresponding policy according to the user's energy usage as needed. Unless otherwise specified in the embodiment, the operations are the same as those in Embodiment 1.

[0203] Steps 1 - 3 are similar to steps 1 - 3 in Embodiment 1.

[0204] Step 4: Optionally, if the UE carries an indication and / or a credit limit value, or the AMF obtains the credit limit from the UDM in step 3, or the AMF supports energy-saving operations / entering the energy-saving state, etc., or this step is a regular step, and the network is energy-saving endogenous, etc., the AMF requests the EE NF / NWDAF / OAM or some other NF to obtain the above-mentioned energy consumption situation that the current UE has used, and may carry the following information:

[0205] 1) The identifier of the terminal.

[0206] 2) S-NSSAI, DNN or APP identifier.

[0207] 3) Service area or Tracking area information.

[0208] 4) The starting calculation moment of the network energy used.

[0209] 5) The ending calculation moment of the network energy used.

[0210] 6) The network energy consumption quota subscribed by the terminal.

[0211] The EE NF / NWDAF / OAM returns the energy information that the current UE has used or an indication (currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.).

[0212] In this step, the AMF can also subscribe to the energy usage notification service of network functions such as the EE NF, that is, when the energy usage of the current UE exceeds the usage limit, an indication is sent to the AMF (such as currently exceeding the credit limit subscribed by the terminal / currently not exceeding the credit limit subscribed by the terminal, etc.) or the energy information already used by the current UE is regularly and cyclically returned to the AMF.

[0213] Step 5: 5-1 The AMF sends a request to the PCF to establish or modify the association of the AM policy (access management policy) and / or the UE policy (terminal policy), and the PCF feeds back the current policy.

[0214] Note: The request sent by the AMF to the PCF here may carry one or several of the following information:

[0215] 1) User network energy consumption quota control indication.

[0216] 2) Indication that the network energy or network energy consumption used by the user or application service reaches or is about to reach the network energy consumption quota subscribed by the terminal.

[0217] 3) User registration area or service scope information.

[0218] 4) Access management policy establishment, modification or update request message.

[0219] 5) Terminal policy establishment, modification or update request message.

[0220] The policy information fed back by the PCF includes but is not limited to the following:

[0221] 1) The service scope (or service area) of the current user. For example, it is possible that when the user reaches their subscribed energy consumption quota, the second network function (such as the PCF) reduces the service scope that the user can use to achieve the effect of energy conservation.

[0222] 2) The updated UE Route Selection Policy (URSP) of the user. For example, among the original single network slice selection assistance information (S-NSSAI) and data network name (DNN) for the user to access a specific service network slice, when the user reaches their subscribed energy consumption quota, the user is selected to be switched to a default S-NSSAI or DNN.

[0223] 3) The identifier of the switched AMF or AMF set.

[0224] 4) Address of the AMF or set of AMFs after switching.

[0225] 5) Updated energy consumption quota.

[0226] 5-2 Execute subsequent registration process

[0227] Step 6: After the terminal registration is completed, it is possible that the AMF triggers the acquisition of the user's energy quota information in Step 6, the same as in Embodiment 1.

[0228] Step 7: Similar to the above Step 5-1, the AMF triggers the establishment or modification of the policy.

[0229] Step 8: According to the latest information obtained, the AMF performs corresponding operations, such as the UE configuration update (UCU) to update the UE's URSP, and the AMF relocation redirects the terminal to a new AMF.

[0230] Embodiment 4

[0231] This embodiment mainly introduces the SMF policy control, as Figure 8 shown, this embodiment includes the following steps:

[0232] Steps 1-4 are similar to Steps 1-4 of Embodiment 1.

[0233] Step 5: Optionally, if the UE carries an indication and / or a credit limit value, or the SMF obtains the credit limit from the UDM in the fourth step, or the SMF supports energy-saving operations / enters the energy-saving state, etc., or this step is a regular step, and the network is energy-saving endogenous, etc., the SMF requests the EE NF / NWDAF / OAM or some other NF to obtain the above energy consumption situation already used by the current UE, and may carry the following information:

[0234] 1) Identifier of the terminal.

[0235] 2) S-NSSAI, DNN or APP identifier.

[0236] 3) Service area or Tracking area information.

[0237] 4) Starting calculation time of the network energy used.

[0238] 5) Ending calculation time of the network energy used.

[0239] 6) Network energy consumption quota subscribed by the terminal.

[0240] EE NF / NWDAF / OAM returns the energy information already used by the current UE or an indication (currently exceeding the terminal's subscribed credit limit / currently not exceeding the terminal's subscribed credit limit, etc.)

[0241] In this step, the SMF can also subscribe to the energy usage notification service of network functions such as EE NF. That is, when the energy usage of the current UE exceeds the usage limit, an indication (currently exceeding the terminal's subscribed credit limit / currently not exceeding the terminal's subscribed credit limit, etc.) is notified to the SMF, or the energy information already used by the current UE is periodically and cyclically returned to the SMF.

[0242] Step 6: The SMF initiates a request to establish or modify the SM policy (session management policy) association with the PCF, and the PCF feeds back the current policy.

[0243] The request sent by the SMF to the PCF here may carry one or several of the following information:

[0244] 1) User network energy consumption quota control indication.

[0245] 2) An indication that the network energy or network energy consumption used by the user or application service has reached or is about to reach the network energy consumption quota subscribed by the terminal.

[0246] 3) User registration area or service scope information.

[0247] 4) Session management policy establishment, modification, or update request message.

[0248] The policy information fed back by the PCF includes but is not limited to the following types:

[0249] 1) The current user's service scope (or service area). For example, it is possible that when the user reaches their subscribed energy consumption quota, the second network function (such as the PCF) reduces the scope of services that the user can use to achieve the effect of energy conservation.

[0250] 2) Updated quality of service (QoS). For example, the performance of the service used by the user is reduced, thereby achieving the effect of energy conservation.

[0251] 3) Updated energy consumption quota.

[0252] Step 7: Perform subsequent registration processes.

[0253] Step 8: After the terminal is registered, it is possible that the SMF triggers the acquisition of the user's energy usage quota information in Step 8, the same as in Embodiment 2.

[0254] Step 9: Similar to Step 6 above, the SMF triggers the establishment or modification of a policy.

[0255] Step 10: According to the latest message obtained, the SMF performs corresponding operations, such as modifying QoS, etc.

[0256] The above combination Figures 2 to 8 describes in detail the terminal control method according to the embodiments of the present application.
