[0540] In this embodiment, taking the fifth network function as PCF as an example, after receiving the eleventh information, the PCF can generate relevant policy information, policy adjustment information or adjustment information based on the eleventh information, and send the generated policy information, policy adjustment information or adjustment information to the corresponding network function, so that the corresponding network function can perform energy adjustment or optimization, and / or, the PCF can perform energy adjustment or optimization according to the eleventh information.

[0541] The communication method of the embodiment of the present application is described in detail below with reference to a specific example.

[0542] FIG8 is a first flow chart of the interaction process of the communication method according to an embodiment of the present application. In this example, the first network function is EECF, the first function is AF, the second network function is AMF, the third network function is SMF, the access network is RAN, the fourth network function is NSACF, the fifth network function is PCF, and the second function is NWDAF. As shown in FIG8 , the method includes:

[0543] Step 801: AF sends first information to EECF through NEF, or sends first information to EECF without NEF, where the first information includes at least one of the following: application identifier, UE identifier, group identifier, any UE identifier (any UE), and second information (or first energy demand related information).

[0544] In some optional embodiments, the AF sending the first information to the EECF through the NEF includes: the AF sending a request message (such as an AF request message) to the EEF through the NEF, where the request message includes the first information.

[0545] The application identifier may include one or more of the following: App ID, triplet, quintuple, FQDN, SDF, and IP address.

[0546] In some optional embodiments, the second information may include one or more of the following:

[0547] Fifteenth information: used to indicate permission or authorization for energy-related processing; or, the fifteenth information is used to allow or authorize energy saving; or, the fifteenth information includes information related to energy saving authorization, or, the fifteenth information includes information related to energy and / or authorization;

[0548] Target energy related information;

[0549] First energy related information;

[0550] Information related to energy consumption thresholds and / or information related to energy consumption thresholds;

[0551] Information related to energy and / or thresholds;

[0552] Energy-related thresholds and / or energy-related thresholds;

[0553] Adjusted or optimized target parameter information or target indicator information.

[0554] Here, the meaning of the above information can be referred to the description of the above embodiments, and will not be repeated here.

[0555] Step 802a: The EECF determines to execute at least one of the following steps 803 to 807 based on the first information, or determines all or part of the information in steps 803 to 807.

[0556] Here, the EECF may determine or generate at least one of the following based on all or part of the first information and / or all or part of the energy-related information:

[0557] All or part of the third information, all or part of the fifth information, all or part of the seventh information, all or part of the ninth information, all or part of the eleventh information, sending all or part of the third information, sending all or part of the fifth information, sending all or part of the seventh information, sending all or part of the ninth information, sending all or part of the eleventh information; wherein, the third information corresponds to the first processing of AMF, the fifth information corresponds to the second processing of SMF, the seventh information corresponds to the third processing of RAN, the ninth information corresponds to the fourth processing of PCF, and the eleventh information corresponds to the fifth processing of PCF.

[0558] Here, the EECF may determine, based on local configuration, to execute at least one of the following steps 803 to 807, or determine all or part of the information in steps 803 to 807. As a possible implementation, the EECF locally configures the relationship between various parameter or indicator adjustments and energy-saving effects. For example, if an AMF serving a UE with a paging cycle of 100 seconds consumes 10W of power and extends the paging cycle to 400 seconds, the power consumption of serving the UE will be reduced to 5W; if the number of sessions served by the SMF is reduced by one, the power consumption will be reduced by 2W to 4W, and so on.

[0559] Step 802b: The EECF may also determine from the NWDAF to execute at least one of the following steps 803 to 807, or determine all or part of the information in steps 803 to 807.

[0560] For example, the EECF sends all or part of the first information and / or all or part of the energy-related information to the NWDAF, and receives response information from the NWDAF, which may include determining to execute at least one of the following steps 803 to 807, or determining all or part of the information in steps 803 to 807.

[0561] It should be noted that either step 802a or step 802b is selected for execution.

[0562] The following steps 803 to 807 can be executed one or more times in no particular order.

[0563] Step 803: EECF sends third information to AMF, where the third information includes at least one of the following: UE identity, group identity, deregistration related information, paging related information, periodic registration update timer, UE-slice MBR related information, DRX related information, UE-AMBR related information, and AMF related energy requirement information.

[0564] The deregistration related information includes at least one of the following: access type and reason value, wherein the reason value is related to energy, such as energy saving requirements.

[0565] The paging related information includes at least one of the following: a paging cycle and a paging range. Optionally, the paging cycle may also be referred to as a target paging cycle, and the paging range may also be referred to as a target paging range.

[0566] Among them, the AMF-related energy requirement information is a requirement for the AMF. For example, the AMF-related energy requirement information requires the AMF to reduce the energy consumption of a certain UE to less than 40% of the current level, but not less than 1W. In other words, the EECF can send specific adjustment content (such as paging cycle, paging range, periodic registration update timer, DRX-related information, UE-slice MBR, UE-AMBR) to the AMF, and can also send AMF-related energy requirement information to the AMF. The AMF will decide how to adjust or optimize the energy.

[0567] Here, the EECF can send the third information directly to the AMF, or it can send the third information to the AMF via at least one network function, which can be, for example, SMF, PCF, etc.

[0568] Here, after receiving the third information, the AMF performs a first process. The first process includes at least one of the following: deregistering at least one UE, modifying or adjusting the paging-related information related to at least one UE, modifying or adjusting the periodic registration update timer information of at least one UE, modifying or adjusting the UE-slice MBR-related information of at least one UE and / or at least one slice, sending the DRX-related information to the access network, sending the DRX-related information to the access network via at least one network function, sending periodic registration update timer information to the UE, sending periodic registration update timer information to the UE via at least one function or entity, modifying or adjusting UE-AMBR-related information, sending UE-AMBR-related information to the access network, and sending UE-AMBR-related information to the access network via at least one network function.

[0569] Specifically, this example may further include at least one of the following steps:

[0570] Step 803a: Perform at least one of the following: modify or adjust the periodic registration update timer information, modify or adjust UE-slice MBR related information, modify or adjust paging related information, modify or adjust UE-AMBR related information.

[0571] Here, the modification or adjustment of the periodic registration update timer information may specifically be modification or adjustment of the periodic registration update timer information of at least one UE. The modification or adjustment of the UE-slice MBR related information may specifically be modification or adjustment of the UE-slice MBR related information of at least one UE and / or at least one slice. The modification or adjustment of the UE-AMBR related information may specifically be modification or adjustment of the UE-AMBR related information of at least one UE.

[0572] Here, the paging related information may include a paging cycle and / or a paging range. The modifying or adjusting the paging related information may specifically be modifying or adjusting a paging cycle and / or a paging range related to at least one UE.

[0573] Step 803b: Send a deregistration request to the RAN;

[0574] Step 803c: Send at least one of the periodic registration update timer information, DRX related information, UE-AMBR related information, and UE-slice MBR related information to the RAN.

[0575] In other examples, step 803 may also be that the AMF sends at least one of periodic registration update timer information, DRX related information, UE-AMBR related information, and UE-slice MBR related information to the RAN through other network functions.

[0576] In other optional examples, it may also include: AMF sending periodic registration update timer information to the UE; and / or, sending periodic registration update timer information to the UE via at least one function or entity.

[0577] The advantage of doing this is that these parameters can all affect energy consumption: when the number of registered users is smaller, the network side energy consumption is lower; when the periodic registration update timer is longer, the frequency of periodic registration updates is lower, that is, the signaling frequency is lower, so the energy consumption is lower; DRX wake-up consumes more power than sleep, so when the wake-up time in the idle DRX cycle is shorter, the energy consumption is lower; when the paging cycle is longer, paging is less frequent, so the energy consumption is lower; when the paging range is smaller, the energy required to perform a paging is also lower.

[0578] Step 804: The EECF sends fifth information to the SMF, where the fifth information includes at least one of the following: session identifier, session release information, session context release information, and SMF-related energy demand information.

[0579] Here, the session release information or session context release information may include a session release instruction.

[0580] Here, the SMF-related energy requirement information is a requirement for the SMF. The SMF-related energy requirement information requires the SMF to reduce the energy consumption of a certain UE to less than 40% of the current level, but not less than 1W. In other words, the EECF can send specific adjustment information (session release related information, session context release related information, etc.) to the SMF, or it can send SMF-related energy requirement information to the SMF, and the SMF will decide how to adjust / optimize it.

[0581] Here, the EECF may send the fifth information directly to the SMF, or may send the fifth information to the SMF via at least one network function, which may be, for example, a PCF.

[0582] Here, after receiving the fifth information, the SMF performs a second process, where the second process includes at least one of the following: releasing at least one session and releasing the context of at least one session.

[0583] Specifically, this example may further include the following steps:

[0584] Step 804a: Execute at least one of the following: release at least one session, release the context of at least one session.

[0585] The advantage of doing this is that these parameters can affect energy consumption: when the number of sessions is smaller, the network side consumes less energy, which can reduce energy consumption.

[0586] Step 805: The EECF sends seventh information to the RAN, where the seventh information includes at least one of the following: UE identity, group identity, air interface release related information, DRX related information, UE-slice MBR related information, UE-AMBR related information, and RAN related energy requirement information.

[0587] Here, the air interface release related information may indicate initiating / performing AN release and / or air interface release.

[0588] Here, the RAN-related energy demand information refers to requirements placed on the RAN. For example, the RAN-related energy demand information requires the RAN to reduce the energy consumption of a particular UE to less than 40% of its current level, but not less than 1W. In other words, the EEF can send specific adjustment details (such as air interface release information and DRX cycle) to the RAN, or it can send RAN-related energy demand information to the RAN, allowing the RAN to independently determine how to adjust / optimize.

[0589] Here, the EECF may send the seventh information directly to the RAN, or may send the seventh information to the RAN via at least one network function, which may be, for example, an AMF, an SMF, etc.

[0590] Here, after receiving the seventh information, the RAN performs a third process. The third process includes at least one of the following: modifying or adjusting DRX-related information, releasing air interface-related information of at least one UE, modifying or adjusting UE-slice MBR-related information of at least one UE and / or at least one slice, and modifying or adjusting UE-AMBR-related information of at least one UE.

[0591] Specifically, this example may further include the following steps:

[0592] Step 805a: Execute one or more of the following: modify or adjust DRX related information, release the air interface, modify or adjust UE-slice MBR related information, modify or adjust UE-AMBR related information.

[0593] The advantage of doing this is that these parameters can affect energy consumption: when the air interface connection is not used, the network side energy consumption is lower; DRX wakeup consumes more power than sleep, so when the wakeup time in the idle DRX cycle is shorter, the energy consumption is lower.

[0594] Step 806: The EECF sends ninth information to the NSACF, including at least one of the following: maximum number of UEs, maximum number of sessions, and NSACF-related energy demand information.

[0595] Here, the NSACF-related energy demand information represents a demand placed on the NSACF. For example, the NSACF-related energy demand information may require the NSACF to reduce the energy consumption of a particular UE to less than 40% of the current level, but not less than 1W. In other words, the EECF may send specific adjustment details (e.g., the maximum number of UEs, the maximum number of sessions) to the NSACF, or it may send NSACF-related energy demand information to the NSACF, which then determines how to adjust / optimize the NSACF.

[0596] Here, the EECF may send the ninth information directly to the NSACF, or may send the ninth information to the NSACF via at least one network function, which may be, for example, an SMF, a PCF, or the like.

[0597] Here, after receiving the ninth information, the NSACF performs a fourth process, wherein the fourth process includes at least one of the following: modifying or adjusting the maximum number of UEs, or modifying or adjusting the maximum number of sessions.

[0598] Specifically, this example may further include the following steps:

[0599] Step 806a: Modify or adjust the maximum number of UEs, modify or adjust the maximum number of sessions.

[0600] Step 807: EECF sends the eleventh information to PCF, including at least one of the following: periodic registration update timer information, DRX related information, UE-AMBR related information, session release information, session context release information, UE-slice MBR related information, and the PCF related energy demand information.

[0601] Here, the PCF-related energy requirement information refers to the requirements placed on the PCF. For example, the PCF-related energy requirement information may require the PCF to reduce the energy consumption of a particular UE to less than 40% of the current level, but not less than 1W. In other words, the EECF may send specific adjustment details (e.g., UE-slice MBR) to the PCF, or it may send PCF-related energy requirement information to the PCF, allowing the PCF to independently determine how to adjust / optimize.

[0602] Here, the EECF may send the eleventh information directly to the PCF, or may send the eleventh information to the PCF via at least one network function, which may be, for example, an SMF.

[0603] Here, after receiving the eleventh information, the PCF performs a fifth process. The fifth process includes at least one of the following: modifying or adjusting UE-slice MBR related information and / or UE-AMBR related information, sending UE-slice MBR related information and / or UE-AMBR related information to at least one of the access network, the second network function, and the third network function, sending UE-slice MBR related information and / or UE-AMBR related information to at least one of the access network, the second network function, and the third network function via at least one network function, sending DRX related information to the second network function, sending DRX related information to the second network function via at least one network function, sending periodic registration update timer information to the second network function, sending periodic registration update timer information to the second network function via at least one network function, sending session release information to the third network function, and sending session release information to the third network function via at least one network function.

[0604] Specifically, this example may further include at least one of the following steps:

[0605] Step 807a: Modify or adjust UE-slice MBR related information and / or UE-AMBR related information;

[0606] Step 807b: Send UE-slice MBR related information and / or UE-AMBR related information.

[0607] Here, the sending of UE-slice MBR related information may specifically include sending UE-slice MBR related information to at least one of the RAN, AMF, and SMF, or may include sending UE-slice related MBR information to at least one of the RAN, AMF, and SMF via at least one network function. Correspondingly, sending UE-AMBR related information may specifically include sending UE-AMBR related information to at least one of the RAN, AMF, and SMF, or may include sending UE-AMBR information to at least one of the RAN, AMF, and SMF via at least one network function.

[0608] Step 808: Optionally, the EECF may send a notification to the AF, where the notification may include at least one of the following: an application identifier, a UE identifier, a group identifier, and fourteenth information related to energy adjustment or optimization.

[0609] Here, the fourteenth information includes at least one of the following:

[0610] sixteenth information, the sixteenth information being used to indicate that energy adjustment or optimization has been performed;

[0611] All or part of third information; the third information includes relevant information for the second network function to perform the first processing related to energy adjustment or optimization and / or fourth information, the fourth information being related to energy adjustment or optimization;

[0612] All or part of fifth information; the fifth information includes relevant information for the third network function to perform the second processing related to energy adjustment or optimization and / or sixth information, the sixth information being related to energy adjustment or optimization;

[0613] All or part of the seventh information; the seventh information includes relevant information and / or eighth information used by the access network to perform a third process related to energy adjustment or optimization, the eighth information being related to energy adjustment or optimization;

[0616] The energy-related information after adjustment or optimization.

[0617] In this example, all or part of the above information may be specific execution content, such as how many sessions are released, how much the DRX cycle is modified, how much the transmission rate is reduced, and so on.

[0618] Here, the energy-related information after adjustment or optimization may include at least one of the following: energy consumption, energy efficiency, renewable energy utilization rate, green energy utilization rate, etc. It may be an absolute value (for example, after optimization, power consumption is reduced to 100W or energy consumption is reduced to 50W·h) and / or a relative value (energy consumption is reduced by 40% after optimization).

[0619] Here, the EECF may communicate with the AF directly, or may communicate with the AF via at least one network function, such as the NEF.

[0623] Step 902: The NEF sends all or part of the first information to the EECF.

[0624] Step 903: The EECF obtains energy-saving authorization information from the UDM. For example, the energy-saving authorization information is included in the contract information and sent to the EECF.

[0625] This step is optional. For example, if the first information obtained by the EECF does not include information related to energy-saving authorization, step 903 may be executed.
