[0051] The terminal control method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0052] As shown in FIG2 , an embodiment of the present application provides a terminal control method 200 , which can be executed by a first network function. In other words, the method can be executed by software or hardware installed in the first network function. The method includes the following steps.

[0053] S202: The first network function obtains first information, where the first information is used to indicate at least one of the following: a network energy consumption quota subscribed by the terminal, network energy consumption, and used network energy.

[0054] In each embodiment of the present 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).

[0055] 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 contract information of the terminal from the Unified Data Management (UDM), and the contract information of the terminal includes the network energy consumption quota signed by the terminal; for another example, the first network function obtains the network energy consumption or used network energy from the Energy Efficiency Network Functions (EE NF), the Network Data Analytics Function (NWDAF), or the Operation Administration and Maintenance (OAM).

[0056] In one embodiment, network energy consumption or used network energy may refer to the services subscribed by the terminal (which may be a single service, multiple services, or all services), application services, or the network energy currently consumed by the terminal. 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.

[0057] 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.

[0058] 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.

[0059] S204: The first network function performs a first operation based on the first information.

[0060] The first operation performed by the first network function may be an operation related to terminal control.

[0061] In the terminal control method provided in an embodiment of the present application, a 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 contracted by the terminal, the network energy consumption, and the network energy used. The first network function performs a first operation based on the first information, thereby controlling the network energy consumption of the terminal, which is beneficial to energy saving of the communication system.

[0062] In the terminal control method provided in the embodiments of the present application, the user's contract signing reflects that the user has signed a contract for energy consumption quota control or a contract for the network energy consumption quota that can be used. The first network function (such as AMF) can obtain information for controlling the user's network energy consumption quota (user granularity, slice granularity, app granularity) during the registration process and interact with the EE NF or other NF / OAM to control the terminal's network energy consumption. The first network function (such as SMF) obtains information for controlling the user's network energy consumption quota (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 terminal's network energy consumption.

[0063] In one embodiment, the first network function performing a first operation based on the first information includes: if the first network function determines that a first condition is satisfied based on the first information, the first network function performing the first operation, where the first condition may include at least one of the following:

[0064] 1) 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.

[0065] 2) The network energy consumption is greater than or equal to a first threshold value. For example, the daily or monthly network energy consumption value is greater than or equal to the first threshold value. The unit of the first threshold value may be J.

[0066] 3) The relevant measurement value of network energy consumption is greater than or equal to the second threshold. For example, 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.

[0067] 4) The current energy efficiency (EE) is greater than or less than a third threshold, and the energy efficiency may be the network energy efficiency caused by the terminal service.

[0068] In one embodiment, the first operation performed by the first network function based on the first information includes at least one of the following:

[0069] 1) Rejecting the registration request of the terminal. For example, if the first network function is an AMF, and during the terminal registration process, the AMF determines based on the first information that 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, then the AMF rejects the registration request of the terminal. For details, please refer to Example 1 below.

[0071] 2) Initiating a deregistration process for the terminal. For example, if the first network function is an AMF, after the terminal successfully registers, the AMF determines, based on the first information, that 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. The AMF then initiates a deregistration process for the terminal. For details, see Example 1 below.

[0072] In this embodiment, the first network function can send a deregistration request message to the terminal, and the deregistration request message includes a reason value, which is used to indicate the above-mentioned first condition, for example, indicating that 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 signed by the terminal.

[0073] 3) Rejecting the session establishment request of the terminal. For example, if the first network function is an SMF, and during the session establishment process of the terminal, the SMF determines based on the first information that 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, then the SMF rejects the session establishment request of the terminal. For details, please refer to Example 2 below.

[0074] In this embodiment, the first network function can send a session establishment request rejection message to the terminal, and the session establishment request rejection message includes a reason value, and the reason value is used to indicate the above-mentioned first condition, for example, indicating that 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 signed by the terminal.

[0075] 4) Initiating a session release process for the terminal. For example, if the first network function is an SMF, after the terminal session is successfully established, the SMF determines, based on the first information, that 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. The SMF then initiates a session release process for the terminal. For details, see Example 2 below.

[0076] In this embodiment, the first network function can send a session release request message to the terminal, and the session release request message includes a reason value, which is used to indicate the above-mentioned first condition, for example, indicating that 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 signed by the terminal.

[0077] In one embodiment, the first network function performing the first operation based on the first information includes: the first network function sending a request message to a second network function, which may be a Policy Control Function (PCF), wherein the request message is used for at least one of the following:

[0078] 1) Access management policy (AM policy) establishment, modification or update.

[0079] 2) Establish, modify or update terminal policy (UE policy).

[0080] 3) Session management policy (SM policy) establishment, modification or update.

[0091] 1) The current user's service scope (or service area). For example, when a user reaches the energy consumption quota they subscribed to, the second network function (such as PCF) reduces the scope of services available to the user to achieve energy saving.

[0092] 2) The user's updated UE Route Selection Policy (URSP). For example, in the network slice Single Network Slice Selection Assistance Information (S-NSSAI) and Data Network Name (DNN) that the user originally used to access a specific service, when the user reaches the energy consumption quota they subscribed to, the user is switched to a default S-NSSAI or DNN.

[0134] 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 in the Non-Access Stratum (NAS) signaling sent to the AMF.

[0135] Optionally, if the information carried in the terminal registration request is in RRC signaling, the RAN may perform AMF selection based on the information carried by the terminal.

[0136] a) If the 5G-S-TMSI / GUAMI is not provided or is provided but the corresponding AMF does not support network energy consumption quota control (also known as energy credit limit control), the RAN performs AMF selection and selects an AMF that supports credit limit control. Here, the RAN may optionally configure the capabilities of AMFs in different service areas / Tracking areas (for example, a list of AMFs that support and do not support credit control in different TAs).

[0137] b) If the RAN cannot select a suitable AMF, the RAN passes the registration request to a pre-configured AMF (e.g., the default AMF). The AMF then performs AMF selection and selects an AMF that supports credit limit control. Here, the AMF performs AMF reselection. 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 the NSSF / EE NF. The acquisition method is that the AMF sends the UE registration information and / or the UE's current TA information and / or credit control indication, etc. The NSSF / EE NF has the ability to have AMFs in different service areas / tracking areas (e.g., a list of AMFs that support and do not support credit control in different TAs). It selects an AMF that can provide service based on the information provided by the AMF and feeds back to the default AMF.

[0138] Step 2: The registration request is sent to the AMF with credit control capability.

[0139] Step 3: The AMF accesses the UDM (carrying the UE's request information in step 1) to obtain the current terminal's contract information, which may contain one or more of the following:

[0140] 1) The network energy consumption quota (such as a credit limit) subscribed by the terminal is one of the following granularities: S-NSSAI, DNN, APP ID, such as S-NSSAI1, DNN1, or APP ID 1: credit limit 1; S-NSSAI1, DNN2, or APP ID 2: credit limit 2; ...

[0141] 2) The network energy consumption quota of each terminal granularity signed by the terminal.

[0142] 3) The start time of network energy consumption quota control (start time).

[0143] 4) End time of network energy consumption quota control.

[0144] 5) The control area information of the network energy consumption quota described above, for example, including network energy consumption quota control in some areas, excluding network energy consumption quota control in some areas, or including network energy consumption quota control in all areas.

[0145] Step 4: Optionally, the AMF requests the EE NF / NWDAF / OAM or another NF to obtain the energy consumption information currently used by the terminal, which may carry the following information:

[0146] 1) The identification of the terminal.

[0147] 2) S-NSSAI, DNN or APP identification.

[0148] 3) Service area or tracking area information.

[0149] 4) The starting time for calculating the network energy used.

[0150] 5) The end time of calculation of network energy used.

[0151] 6) The network energy consumption quota contracted by the terminal.

[0152] EE NF / NWDAF / OAM returns the energy information currently used by the UE or an indication (currently exceeds the credit limit of the terminal contract / currently does not exceed the credit limit of the terminal contract, etc.).

[0153] In this step, the AMF may also subscribe to the energy usage notification service of network functions such as EE NF, that is, when the current UE's energy usage exceeds the usage limit, the AMF is notified of an indication (currently exceeding the credit limit contracted by the terminal / currently not exceeding the credit limit contracted by the terminal, etc.) or the energy information used by the current UE is returned to the AMF regularly and cyclically.

[0154] Step 5: If the energy credit used by the current UE reaches the energy credit it has signed, the AMF rejects the terminal's registration request and carries the cause value "credit limit reached" in the registration request rejection message.

[0155] It should be noted that if the energy quota contracted by the UE is at a per UE granularity, the process terminates at step 5.

[0156] If the energy quota signed by the UE is for a certain type of service, such as a certain S-NSSAI, DNN or APP ID, the AMF rejects the registration request of the S-NSSAI corresponding to the service that reaches the total energy amount, but continues to execute the registration request of other services or services signed by the UE, that is, continue to execute the following steps.

[0157] Step 6: AMF triggers credit limit control for the UE. It should be noted that this step can occur after the terminal is registered, for example, it is actively triggered by the AMF.

[0158] Step 7: The AMF requests the EE NF or other network functions to feedback the energy consumption value used by the current UE. Alternatively, the AMF subscribes to the EE NF or other network functions to monitor the energy consumption value used by 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 energy consumption information used by the current UE or an indication (currently exceeding the terminal's contracted credit limit / currently not exceeding the terminal's contracted credit limit, etc.).

[0159] Here, there is a possibility that the user's contract does not contain a credit limit value, or another possibility is that the user's contract only contains service information for implementing the credit limit. The credit limit is stored in the corresponding network function such as the EE NF, and the EE NF controls according to the configured credit limit.

[0160] Step 8: If the energy credit used by the current UE reaches the energy credit it has subscribed to, the AMF initiates the deregistration process and carries the cause value (cause value) in the deregistration request message: credit limit reached (the total amount of network energy subscribed to by the user has been reached).

[0161] If the energy quota subscribed by the UE is per UE granularity, the process is terminated and the AMF initiates the deregistration of all registered S-NSSAIs of the terminal.

[0162] If the energy quota signed by the UE is for a certain type of service, such as a certain S-NSSAI, DNN or APP ID, the AMF only initiates the deregistration request of the S-NSSAI corresponding to the service that reaches the total energy amount, and the registration status of other S-NSSAI remains unchanged

[0163] In all embodiments of the present application, EE NF / NWDAF / OAM may also be other core networks such as PCF and CHF.

[0164] As another implementation method of Example 1, as shown in Figure 4, optionally, UDM may not store the network energy consumption quota information (referred to as limit information), but the AMF directly interacts with the EE NF, etc. to obtain it, and the rest of the process is the same as the above Example 1.

[0165] There are several possibilities for the above process:

[0166] The UE carries the indication information of step 1. Upon receiving the indication, the AMF actively triggers step 4 to obtain the limit information.

[0167] The UE does not carry an indication, and the AMF proactively triggers step 4 to obtain the limit information.

[0168] The UE carries the indication and the contracted credit limit. The AMF only obtains the energy usage from step 4. The EE NF does not have relevant information about the credit limit.

[0169] Example 2

[0170] This embodiment mainly introduces SMF access control. As shown in FIG5 , this embodiment includes the following steps:

[0171] Step 1: The UE initiates a PDU session establishment request, optionally carrying relevant information as described in Example 1, indicating that it has signed up for the credit limit control service.

[0172] Similar to step 1 of embodiment 1, the credit limit control may have an additional PDU session or QoS flow granularity, and the provided information may also include at least one of the following:

[0173] 1) QoS reference and network energy consumption quota for QoS reference.

[0174] 2) Personal QoS parameters and network energy consumption quota of personal QoS parameters.

[0175] 3) APP logo and network energy consumption quota of APP logo.

[0176] Step 2: Optionally, the AMF may perform SMF selection based on the information carried by the UE and select an SMF with credit limit control capability.

[0177] Step 3: AMF initiates a PDU session connection carrying the information requested by the UE.

[0178] Step 4: SMF obtains the contract information of UDM, which is the same as the information obtained by UDM in Example 1, plus more fine-grained information:

[0179] 1) QoS reference and network energy consumption quota for QoS reference.

[0180] 2) Personal QoS parameters and network energy consumption quota of personal QoS parameters.

[0181] 3) APP logo and network energy consumption quota of APP logo.

[0182] Step 5: The SMF requests the EE NF / NWDAF / OAM or another NF to obtain the energy consumption information currently used by the UE, which may carry the following information:

[0183] 1) The identification of the terminal.

[0184] 2) S-NSSAI, DNN or APP identification.

[0185] 3) Service area or tracking area information.

[0186] 4) The starting time for calculating the network energy used.

[0187] 5) The end time of calculation of network energy used.

[0188] 6) The network energy consumption quota contracted by the terminal.

[0189] EE NF / NWDAF / OAM returns the energy information currently used by the UE or an indication (currently exceeds the credit limit of the terminal contract / currently does not exceed the credit limit of the terminal contract, etc.).

[0190] 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 current UE's energy usage exceeds the usage limit, the SMF is notified of an indication (currently exceeding the credit limit contracted by the terminal / currently not exceeding the credit limit contracted by the terminal, etc.) or the energy information used by the current UE is returned to the SMF regularly and cyclically.

[0191] Step 6: If the energy credit used by the current UE reaches the energy credit it has signed, the SMF rejects the terminal's PDUsession establishment request and carries the cause value "credit limit reached" (the total amount of energy signed by the user) in the request rejection message.

[0192] Step 7: The rejection request is fed back to the UE.

[0193] 7-0: If the credit limit is not reached, the PDU session establishment process continues.

[0194] Steps 8 to 9: SMF requests EE NF and other network functions to feedback the energy consumption value used by the current UE, or SMF subscribes to the service of EE NF and other network functions to monitor the energy consumption value used by the current UE. The information carried includes but is not limited to the content in the feedback contract information. When the credit limit is exceeded, EE NF will feedback the energy information used by the current UE or an indication (currently exceeding the credit limit of the terminal contract / currently not exceeding the credit limit of the terminal contract, etc.).

[0195] Here, there is a possibility that the user's contract does not contain a credit limit value, or another possibility is that the user's contract only contains service information for implementing the credit limit. The credit limit is stored in the corresponding network function such as the EE NF, and the EE NF controls according to the configured credit limit.

[0196] Step 10: If the energy credit used by the current UE reaches the energy credit it has signed, the SMF initiates the PDUsession release process and carries the cause value: credit limit reached (the total amount of energy signed by the user) in the feedback message.

[0197] As another implementation of the second embodiment, as shown in FIG6 , optionally, the UDM may not store the limit information, but the SMF may directly interact with the EE NF to obtain the limit information, and the rest of the process is the same as that of the first embodiment.

[0198] There are several possibilities for the above process:

[0199] The UE carries the indication information of step 1, and the SMF receives the indication and actively triggers step 5 to obtain the limit information

[0200] UE does not carry any information such as indication, and SMF actively triggers step 5 to obtain limit information

[0201] UE carries the indication and the contracted credit limit. SMF only obtains the energy usage from step 5. EE NF does not have the relevant information of credit limit.

[0202] Example 3

[0203] This embodiment mainly introduces AMF policy control. As shown in Figure 7, this embodiment includes the following steps:

[0204] The difference between this embodiment and embodiment one is that it does not simply control whether the terminal is registered, but allows the AMF to modify / update the corresponding policy as needed according to the user's energy usage during the registration process or after the user registers. If the implementation example is not specifically explained, its operation is the same as that of embodiment one.

[0205] Steps 1-3 are similar to those in the first embodiment.

[0206] Step 4: Optionally, if the UE carries an indication and / or credit limit value, or the AMF obtains the credit limit from the UDM in step 3, or the AMF supports energy-saving operations / enters energy-saving states, or this step is a regular step and the network is energy-saving, the AMF requests the EE NF / NWDAF / OAM or another NF to obtain the above energy consumption information currently used by the UE, which may carry the following information:

[0207] 1) The identification of the terminal.

[0208] 2) S-NSSAI, DNN or APP identification.

[0209] 3) Service area or tracking area information.

[0210] 4) The starting time for calculating the network energy used.

[0211] 5) The end time of calculation of network energy used.

[0212] 6) The network energy consumption quota contracted by the terminal.

[0213] EE NF / NWDAF / OAM returns the energy information currently used by the UE or an indication (currently exceeds the credit limit of the terminal contract / currently does not exceed the credit limit of the terminal contract, etc.).

[0214] In this step, the AMF may 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, the AMF is notified of an indication (currently exceeding the credit limit contracted by the terminal / currently not exceeding the credit limit contracted by the terminal, etc.) or the energy information used by the current UE is returned to the AMF regularly and cyclically.

[0215] Step 5: 5-1AMF initiates an AM policy (access management policy) and / or UE policy (terminal policy) association establishment or modification request to PCF, and PCF feeds back the current policy.

[0216] Note: The request sent by AMF to PCF may carry one or more of the following information:

[0217] 1) User network energy consumption quota control indication.

[0218] 2) An indication that the network energy used or the network energy consumption of the user or application service has reached or is about to reach the network energy consumption quota contracted by the terminal.

[0219] 3) The user’s registration area or service scope information.

[0220] 4) Access management policy establishment, modification or update request message.

[0221] 5) Terminal policy establishment, modification or update request message.

[0222] The policy information fed back by PCF includes but is not limited to the following:

[0223] 1) The current user's service scope (or service area). For example, when a user reaches the energy consumption quota they subscribed to, the second network function (such as PCF) may reduce the scope of services available to the user to achieve energy saving.

[0224] 2) The user's updated UE Route Selection Policy (URSP). For example, in the network slice Single Network Slice Selection Assistance Information (S-NSSAI) and Data Network Name (DNN) that the user originally used to access a specific service, when the user reaches the energy consumption quota they subscribed to, the user is switched to a default S-NSSAI or DNN.

[0225] 3) Identification of the AMF or AMF set (AMF set) after switching.

[0226] 4) The address of the AMF or AMF set after switching.

[0227] 5) Updated energy consumption quota.

[0228] 5-2 Execute the subsequent registration process

[0229] Step 6: After the terminal registration is completed, the AMF may trigger the acquisition of the user's energy quota information in step 6, which is the same as Example 1.

[0230] Step 7: Same as step 5-1 above, establishment or modification of AMF trigger policy.

[0231] Step 8: Based on the latest message obtained, AMF performs corresponding operations, such as UE configuration update (UCU) to update the UE's URSP, and AMF relocation redirects the terminal to the new AMF.

[0232] Example 4

[0233] This embodiment mainly introduces SMF policy control. As shown in FIG8 , this embodiment includes the following steps:

[0234] Steps 1-4 are similar to those in the first embodiment.

[0235] Step 5: Optionally, if the UE carries an indication and / or credit limit value, or the SMF obtains the credit limit from the UDM in step 4, or the SMF supports energy-saving operations / enters energy-saving states, or this step is a regular step and the network is energy-saving, the SMF requests the EE NF / NWDAF / OAM or another NF to obtain the above energy consumption information used by the current UE, which may carry the following information:

[0236] 1) The identification of the terminal.

[0237] 2) S-NSSAI, DNN or APP identification.

[0238] 3) Service area or tracking area information.

[0239] 4) The starting time for calculating the network energy used.

[0240] 5) The end time of calculation of network energy used.

[0241] 6) The network energy consumption quota contracted by the terminal.

[0242] EE NF / NWDAF / OAM returns the energy information currently used by the UE or an indication (currently exceeds the terminal's contracted credit limit / currently does not exceed the terminal's contracted credit limit, etc.)

[0243] 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 current UE's energy usage exceeds the usage limit, the SMF is notified of an indication (currently exceeding the credit limit contracted by the terminal / currently not exceeding the credit limit contracted by the terminal, etc.) or the energy information used by the current UE is returned to the SMF regularly and cyclically.

[0244] Step 6: SMF initiates an SM policy (session management policy) association establishment or modification request to PCF, and PCF feeds back the current policy.

[0245] The request sent by the SMF to the PCF may carry one or more of the following information:

[0246] 1) User network energy consumption quota control indication.

[0247] 2) An indication that the network energy used or the network energy consumption of the user or application service has reached or is about to reach the network energy consumption quota contracted by the terminal.

[0248] 3) The user’s registration area or service scope information.

[0249] 4) Session management policy establishment, modification or update request message.

[0250] The policy information fed back by PCF includes but is not limited to the following:

[0251] 1) The current user's service scope (or service area). For example, when a user reaches the energy consumption quota they subscribed to, the second network function (such as PCF) may reduce the scope of services available to the user to achieve energy saving.

[0252] 2) Updated Quality of Service (QoS), for example, reducing the performance of the service used by the user, thereby achieving energy saving.

[0253] 3) Updated energy consumption quota.

[0254] Step 7: Follow the subsequent registration process.

[0255] Step 8: After the terminal registration is completed, the SMF may trigger the acquisition of the user's energy quota information in step 8, which is the same as in the second embodiment.

[0256] Step 9: Same as step 6 above, establish or modify the SMF trigger policy.

[0257] Step 10: Based on the latest information obtained, SMF performs corresponding operations, such as modifying QoS.
