Description

Information processing, transmission method, device and communication equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on September 11, 2023, with application number 202311163169.4 and application name “Information processing, transmission method, device and communication equipment”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an information processing and transmission method, apparatus, and communication equipment. Background Art

[0003] User Equipment (UE) can transmit data to an application server in a data network (DN) or receive data from an application server in a DN through a wireless mobile communication network. In different areas, different local networks can be deployed to access the same data network and provide the same application / service. In this way, when the UE is in a specific area, the network can select a local data network access point for the UE to access the data network, allowing the UE to transmit data between the local network and the local application server, thereby reducing service latency, reducing core network load, and improving service experience. This scenario is also called edge computing.

[0004] However, when there are multiple local networks, how to select a data network access point to reduce the energy consumption of the network or UE and improve the energy efficiency performance of the network or UE is an urgent problem to be solved.

[0176] First, based on the technical solutions provided by the present disclosure, some technical terms that may be involved are introduced.

[0177] 1. Protocol Data Unit (PDU) session establishment and modification based on data network access points

[0178] In the 5G mobile communication system, the data network access point is identified by the Data Network Access Identifier (DNAI). When the UE requests to establish a PDU session, the network can select a local DNAI for the PDU session based on the UE location, subscription data, and network policy, and then determine the UPF (called PDU Session Anchors (PSA)) that can access the DNAI, thereby establishing a PDU session between the UE and the UPF. After the PDU session is established, the network can also modify the data transmission path of the PDU session based on changes in the UE location, subscription data, and network policy, that is, select a new DNAI, and change, add or delete the PSA accordingly. If necessary, it is necessary to add an uplink classifier / Branching Point (UL CL / BP) UPF between the UE and the PSA, or delete or change the UL CL / BP UPF.

[0179] 2. Energy consumption and energy efficiency of communication systems / communication equipment

[0180] The energy consumption of communication equipment refers to the energy consumed by communication equipment to support communication operations and complete communication tasks. Energy consumption can be calculated by measuring the power of the equipment over a period of time. The energy consumption of the entire communication system is the sum of the energy consumption of all communication equipment in the system. The energy efficiency of the communication system / communication equipment reflects the efficiency of energy consumption and can be defined as the ratio of the amount of data transmitted to energy consumption, or the ratio of the communication area covered (or served) to energy consumption. Energy efficiency can be measured for the entire network, subnet (such as a wireless access network), individual network equipment, communication site (such as a data center), UE, etc.

[0181] Based on the analysis, the embodiments of the present disclosure provide an information processing and transmission method, apparatus, and communication device to select a better data network access point, reduce the energy consumption of the network or UE, and improve the energy efficiency performance of the network or UE.

[0182] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0183] As shown in FIG2 , an embodiment of the present disclosure provides an information processing method, which is performed by a first network function and includes:

[0184] Step S201, obtaining first information of at least one data network access point;

[0185] The first information includes at least one of the following: energy consumption information and energy efficiency information.

[0186] It should be noted that the energy consumption information includes energy consumption information of the network or UE using the data network access point, and the energy efficiency information includes energy efficiency information of the network or UE using the data network access point.

[0187] In some embodiments, the network uses the energy consumption information of the data network access point, including energy consumption information of a network function that accesses or serves the data network access point.

[0188] In some embodiments, the network uses energy efficiency information of the data network access point, including energy efficiency information of a network function that accesses or serves the data network access point.

[0189] In some embodiments, the UE using the energy consumption information of the data network access point includes: energy consumption information of the UE transmitting data to the data network access point. Specifically, the energy consumption information of the UE transmitting data to the data network access point includes: energy consumption information of the UE transmitting data to an edge application server (EAS) corresponding to the data network access point.

[0190] In some embodiments, the UE using the energy efficiency information of the data network access point includes: the energy efficiency information of the UE transmitting data to the data network access point. Specifically, the energy efficiency information of the UE transmitting data to the data network access point includes: the energy efficiency information of the UE transmitting data to the EAS corresponding to the data network access point.

[0191] Step 202: Determine data network access point information of a protocol data unit (PDU) session based on the first information;

[0192] Step 203: triggering establishment or modification of the PDU session based on the data network access point information.

[0193] In some embodiments, the first network function mentioned in the embodiments of the present disclosure may be: a network function that provides services for applications, such as an application function (AF); a network function that implements network capability exposure, such as a network capability exposure function (NEF); a network function that implements network energy management, such as a network energy management function (NEMF); a network function that implements policy control, such as a policy control function (PCF); a network function that implements session management, such as a session management function (SMF).

[0194] It should be noted that in the embodiment of the present disclosure, the data network access point information is determined based on the energy consumption information and / or energy efficiency information of at least one data network access point, so that the terminal or network can use the PDU session that matches the data network access point information for data transmission, thereby reducing the energy consumption of the network or UE and improving the energy efficiency performance of the network or UE.

[0195] It should be noted that the energy efficiency mentioned in the embodiments of the present disclosure is used to reflect the efficiency of energy consumption. It can be obtained by the ratio of the amount of data transmitted to the energy consumption, that is, the energy efficiency is the ratio of the amount of data transmitted to the energy consumption, or it can be obtained by the ratio of the communication area covered or served to the energy consumption, that is, the energy efficiency is the ratio of the communication area to the energy consumption.

[0196] In some embodiments, the energy efficiency information may be represented by an energy efficiency level, and the energy consumption information may be represented by an energy consumption level.

[0197] In some embodiments, the data network access point information includes one of the following:

[0198] A11, Data Network Access Point Identifier (DNAI) list;

[0199] It should be noted that the data network access point mentioned in the embodiment of the present disclosure is indicated by DNAI, that is, the data network access point and the DNAI are one-to-one corresponding, that is, one data network access point corresponds to one DNAI; therefore, the energy consumption of the data network access point in the embodiment of the present disclosure can also be referred to as the energy consumption of the DNAI; the energy efficiency of the data network access point can also be referred to as the energy efficiency of the DNAI.

[0200] In this case, it can be understood that the first network function determines one or more DNAIs based on the first information.

[0201] Wherein, the DNAI list satisfies at least one of the following:

[0202] A111. The energy consumption of the data network access point indicated by the DNAI in the DNAI list is less than or equal to a first preset value;

[0203] It should be noted that the energy consumption of the data network access point is less than or equal to the first preset value, which can be understood as the low energy consumption of the data network access point, that is, the data network access point is a low-energy data network access point; that is, all DNAIs in the DNAI list in this case indicate low-energy data network access points.

[0204] A112. The energy efficiency of the data network access point indicated by the DNAI in the DNAI list is greater than or equal to a second preset value;

[0205] It should be noted that the energy efficiency of the data network access point is greater than or equal to the second preset value, which can be understood as the high energy efficiency of the data network access point, that is, the data network access point is a high-energy-efficiency data network access point; that is, all DNAIs in the DNAI list in this case indicate high-energy-efficiency data network access points.

[0206] A113. The data network access point indicated by the DNAI in the DNAI list supports the target application;

[0207] This situation can be understood as all DNAIs in the DNAI list indicating data network access points that support the target application.

[0208] A12, target DNAI;

[0209] In this case, it can be understood that the first network function determines a specific DNAI based on the first information.

[0210] The target data network access point corresponding to the target DNAI satisfies at least one of the following:

[0211] A121. The energy consumption of the target data network access point is less than or equal to a third preset value;

[0212] It should be noted that the target data network access point having energy consumption less than or equal to the third preset value can be understood as the target data network access point being a low-energy data network access point; it can be understood that the first network device determines a low-energy data network access point.

[0213] A122. The energy efficiency of the target data network access point is greater than or equal to a fourth preset value;

[0214] It should be noted that the energy efficiency of the target data network access point being greater than or equal to the fourth preset value can be understood as the target data network access point being a high-energy-efficiency data network access point; it can be understood as the first network device determining a high-energy-efficiency data network access point.

[0215] A123, the energy consumption of the target data network access point is less than the energy consumption of the data network access points corresponding to other DNAIs except the target DNAI in the DNAI list;

[0216] This situation can be understood as: the first network function side pre-sets a DNAI list, and the target DNAI is selected from the DNAI list. Specifically, the target DNAI is the DNAI corresponding to the data network access point with the lowest energy consumption in the DNAI list.

[0217] A124. The energy efficiency of the data network access point indicated by the target DNAI is greater than the energy efficiency of the data network access points corresponding to other DNAIs in the DNAI list except the target DNAI;

[0218] This situation can be understood as: the first network function side pre-sets a DNAI list, and the target DNAI is selected from the DNAI list. Specifically, the target DNAI is the DNAI corresponding to the data network access point with the highest energy efficiency in the DNAI list.

[0219] It should be noted here that since the present disclosure processes PDU sessions, the network function that implements session management can directly process PDU sessions, and the network function that cannot implement session management cannot process PDU sessions; therefore, in the embodiment of the present disclosure, the first network function is classified into two categories, one is the network function that can implement session management, such as SMF; the other is the network function that does not directly perform session management but can affect session management by providing relevant parameters, such as network functions that provide services for applications, network functions that realize network capability opening, network functions that realize network energy management, network functions that realize policy control, etc.

[0220] The application of these two types of network functions is described in detail below.

[0221] 1. The first network function is a network function that does not directly manage sessions but can influence session management by providing relevant parameters.

[0222] It should be noted that in this case, the first network function usually determines the DNAI list first, and then notifies the network function that implements session management of the DNAI list. That is to say, when providing the DNAI list to the network function that implements session management, the first network function needs to consider the energy efficiency and / or energy consumption of the data network access point, and only provide DNAIs with low energy consumption and / or high energy efficiency.

[0223] In some embodiments, the data network access point information includes A11.

[0224] In some embodiments, triggering establishment or modification of the PDU session based on the data network access point information includes:

[0225] The data network access point information is sent to a second network function, where the data network access point information is used to trigger the second network function to establish or modify the PDU session based on the data network access point information.

[0226] In some embodiments, the second network function in the embodiments of the present disclosure is a network function that implements session management, such as SMF.

[0227] It should be noted here that after receiving the DNAI list sent by the first network function, the network function that implements session management needs to select a suitable DNAI from the DNAI list, and then establish or modify the PDU session based on the DNAI.

[0228] In some embodiments, the method further comprises:

[0229] Determine energy consumption information and / or energy efficiency information of the data network access point indicated by each DNAI in the DNAI list.

[0230] It should be noted that by determining the energy consumption information and / or energy efficiency information of the data network access point indicated by each DNAI in the DNAI list, and then sending the information together with the DNAI list to the network function that implements session management, the network function that implements session management can be assisted in selecting the DNAI based on the energy consumption information and / or energy efficiency information, thereby improving the accuracy of the DNAI selection.

[0231] 2. The first network function is a network function capable of implementing session management

[0232] It should be noted that in this case, it is usually the first network function that directly determines the target DNAI, and then establishes or modifies the PDU session based on the target DNAI; that is, when selecting a data network access point, the first network function gives priority to using a DNAI with low energy consumption or high energy efficiency, and / or does not use a DNAI with high energy consumption or low energy efficiency. For example: the first network function deletes the anchor UPF of the PDU session connected to the DNAI with high energy consumption or low energy efficiency, and selects and uses the anchor UPF of the PDU session connected to the DNAI with low energy consumption or high energy efficiency.

[0233] With respect to the above two types of network functions, in some embodiments, the specific implementation of triggering the establishment or modification of the PDU session based on the data network access point information includes one of the following:

[0234] B11. Triggering the UPF that can access the DNAI indicated by the data network access point information as the anchor UPF of the PDU session;

[0235] It should be noted that the UPF that can access the DNAI indicated by the data network access point information can be understood as: a UPF that can access the data network access point corresponding to the DNAI indicated by the data network access point information.

[0236] In some embodiments, for a first network function that does not directly perform session management but can influence session management by providing relevant parameters, the first network function needs to send a DNAI list to a network function that can implement session management. Each DNAI in the DNAI list can be selected as a candidate DNAI for the network function that can implement session management. When the network function that implements session management is used in a specific application, it will usually select a DNAI from the DNAI list and use the UPF that can access the data network access point corresponding to the selected DNAI as the anchor point UPF of the PDU session.

[0237] In some embodiments, for the first network function that is a network function capable of implementing session management, the first network function directly selects a target DNAI and uses the UPF that can access the data network access point corresponding to the selected target DNAI as the anchor point UPF of the PDU session.

[0238] B12. Trigger a change in the anchor UPF of the PDU session, and use the UPF that can access the DNAI indicated by the data network access point information as the new anchor UPF of the PDU session;

[0239] In some embodiments, for a first network function that does not directly perform session management but can influence session management by providing relevant parameters, the first network function needs to send a DNAI list to a network function that can implement session management. Each DNAI in the DNAI list can be selected as a candidate DNAI for the network function that can implement session management to implement a change in the anchor point UPF of the PDU session. When the network function that implements session management is used in a specific application, it will usually select a DNAI from the DNAI list and use the UPF that can access the data network access point corresponding to the selected DNAI as the new anchor point UPF of the PDU session.

[0240] In some embodiments, for the first network function that is a network function capable of implementing session management, the first network function directly selects a target DNAI and uses the UPF that can access the data network access point corresponding to the selected target DNAI as the new anchor point UPF of the PDU session.

[0241] B13. Trigger adding the PDU session anchor UPF, and add the UPF that can access the DNAI indicated by the data network access point information as the new anchor UPF of the PDU session;

[0242] In some embodiments, for a first network function that does not directly perform session management but can influence session management by providing relevant parameters, the first network function needs to send a DNAI list to a network function that can implement session management. Each DNAI in the DNAI list can be selected as a candidate DNAI for the network function that can implement session management to achieve the increase of the anchor point UPF of the PDU session. When the network function that implements session management is used in a specific application, it will usually select a DNAI from the DNAI list and use the UPF that can access the data network access point corresponding to the selected DNAI as the new anchor point UPF of the PDU session.

[0243] In some embodiments, for the first network function that is a network function capable of implementing session management, the first network function directly selects a target DNAI and uses the UPF that can access the data network access point corresponding to the selected target DNAI as the new anchor point UPF of the PDU session.

[0244] The above implementation can be understood as, whether the PDU session is established or the PDU session is modified (changed or added), it is necessary to determine the anchor point UPF based on the data network access point information, and the UPF that can access the DNAI indicated by the data network access point information is used as the anchor point UPF of the PDU session.

[0245] In some embodiments, the energy consumption information or energy efficiency information mentioned in the embodiments of the present disclosure includes at least one of the following:

[0246] C11. The network or UE uses the data network access point to transmit energy consumption information or energy efficiency information of the target PDU session or each PDU session;

[0247] This situation can be understood as the energy consumption information or energy efficiency information is for the target PDU session or each PDU session.

[0248] In some embodiments, the target PDU session may be any one or more PDU sessions, such as one or more PDU sessions corresponding to a specific data network name DNN and / or network slice (identified by single network slice selection assistance information (S-NSSAI)). When targeting a target PDU session, it is necessary to obtain energy consumption information or energy efficiency information for the target PDU session; when targeting each PDU session, it is necessary to obtain energy consumption information or energy efficiency information for each PDU session separately.

[0249] C12. Energy consumption information or energy efficiency information of data transmitted by the network to the target UE or each UE using the data network access point;

[0250] This situation can be understood as the energy consumption information or energy efficiency information being for the target UE or each UE.

[0251] In some embodiments, the target UE may be any one or more UEs. When targeting a target UE, energy consumption information or energy efficiency information needs to be acquired for the target UE; when targeting each UE, energy consumption information or energy efficiency information needs to be acquired for each UE separately.

[0252] C13. The network or UE uses the data network access point to transmit energy consumption information or energy efficiency information of the target application or each application;

[0253] This situation can be understood as the energy consumption information or energy efficiency information being targeted at the target application or each application.

[0254] In some embodiments, the target application may be any one or more applications. When targeting a target application, energy consumption information or energy efficiency information needs to be acquired for the target application; when targeting each application, energy consumption information or energy efficiency information needs to be acquired for each application separately.

[0255] C14. Energy consumption information or energy efficiency information of the network or UE using the data network access point to transmit data in the target network slice;

[0256] This situation can be understood as the energy consumption information or energy efficiency information is for the target network slice.

[0257] In some embodiments, the target network slice may be any one or more network slices. When targeting a target network slice, it is necessary to obtain energy consumption information or energy efficiency information for the target network slice.

[0258] It should be noted that the above C11-C14 can be understood as limiting the granularity of energy consumption information or energy efficiency information, that is, the collection granularity or acquisition granularity.

[0259] In some embodiments, the energy consumption information may include statistical information or predicted information of energy consumption, that is, the statistical information or predicted information can represent the energy consumption level.

[0260] In some embodiments, the energy efficiency information includes statistical information or prediction information of energy efficiency, that is, the statistical information or prediction information can represent the energy efficiency level.

[0261] In some embodiments, the specific implementation of obtaining the first information of at least one data network access point includes:

[0262] obtaining the first information of the at least one data network access point from a third network function or terminal;

[0263] The third network function includes at least one of the following:

[0264] D11, a control plane function for accessing or serving the data network access point;

[0265] D12, user plane function for accessing or serving the data network access point;

[0266] D13, policy control function;

[0267] D14, network energy management function;

[0268] D15, network capability exposure function;

[0269] D16: Network data analysis function, for example, may be a network data analysis function (NWDAF).

[0270] It should be noted here that, usually, the first network device obtains statistical information or prediction information of energy consumption and / or statistical information or prediction information of energy efficiency from the network data analysis function.

[0271] In some embodiments, the statistical information or prediction information may also be referred to as analytical information.

[0272] In some embodiments, the specific implementation of obtaining the first information of the at least one data network access point from the third network function or terminal includes:

[0273] Sending a first message to the third network function or the UE, where the first message is used to request the first information of the at least one data network access point;

[0274] A second message is received from the third network function or the UE, where the second message carries the first information of the at least one data network access point.

[0275] That is, when obtaining the first information, the first network function needs to first send a first message to the corresponding network function or UE to request the network function or UE to provide the first information. In some embodiments, if the first network function sends the first message to the UE, the corresponding UE provides energy efficiency information of the UE using the data network access point, and / or energy consumption information of the UE using the data network access point. In some embodiments, if the first network function sends the first message to the corresponding other network function, the corresponding network function provides energy consumption information of the network or UE using the data network access point, and / or energy efficiency information of the network or UE using the data network access point. It should also be noted that the energy consumption information of the UE using the data network access point provided by the other network function, and / or the energy efficiency information of the UE using the data network access point, is also obtained from the corresponding UE.

[0276] In some embodiments, the first message carries the DNAI of the at least one data network access point and limiting information of the first information.

[0277] In some embodiments, if at least one data network access point accesses the same data network name (DNN) or multiple DNNs, the first message may also carry the DNN.

[0278] The limiting information of the first information includes at least one of the following:

[0283] It should be noted that the above E12 and E13 indicate the granularity of the requested energy consumption information or energy efficiency information.

[0284] The specific application of the present disclosure is described below with examples.

[0285] Application Scenario 1: The first network function is AF

[0286] As shown in Figure 3, the specific implementation process includes:

[0287] Step 31: The AF obtains first information of at least one data network access point;

[0288] Specifically, the AF obtains energy consumption information and / or energy efficiency information of at least one DNAI from a network function (NF) (e.g., NEMF, NEF, PCF, SMF, or UPF) or a UE, or obtains analysis information (e.g., statistical information or prediction information) of energy consumption and / or energy efficiency of at least one DNAI from an NWDAF.

[0289] Specifically, it may include one of the following steps:

[0290] Step 31a: AF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with NEMF.

[0291] Step 31b: The AF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with the NEF.

[0292] Step 31c: The AF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with the UPF.

[0293] Specifically, the AF sends a first message to one or more UPFs directly or through the NEF to request energy consumption information and / or energy efficiency information of at least one DNAI. The first message carries one or more DNAIs, which are used to indicate the request / subscription network access to the energy consumption information and / or energy efficiency information of the specified DNAI; or carries a DNN, which is used to indicate the request / subscription network access to the energy consumption information and / or energy efficiency information of one or more DNAIs of the DNN.

[0294] The UPF replies / reports the energy consumption information and / or energy efficiency information of the network access DNAI to the AF. Specifically, the UPF determines the energy consumption information and / or energy efficiency information of the UPF accessing the specified DNAI and sends it to the AF based on the energy consumption information and / or energy efficiency information of the UPF currently accessing the specified DNAI, or the statistical information of the energy consumption and / or energy efficiency of the previous access to the specified DNAI or the predicted information of the energy consumption and / or energy efficiency of the future access to the specified DNAI.

[0295] Step 31d: AF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with SMF.

[0296] Specifically, the AF sends a first message to one or more SMFs directly or through the NEF to request energy consumption information and / or energy efficiency information of at least one DNAI. The first message carries one or more DNAIs, which are used to indicate the request / subscription network access to the energy consumption information and / or energy efficiency information of the specified DNAI; or carries a DNN, which is used to indicate the request / subscription network access to the energy consumption information and / or energy efficiency information of one or more DNAIs of the DNN.

[0297] The SMF replies / reports the energy consumption information and / or energy efficiency information of the network access DNAI to the AF. The energy consumption information and / or energy efficiency information of the network access DNAI reported by the SMF here may include: the energy consumption information and / or energy efficiency information of the SMF serving the DNAI, and / or the energy consumption information and / or energy efficiency information of the UPF accessing the DNAI.

[0298] Step 31e: AF obtains energy consumption information and / or energy efficiency information of DNAI by interacting with PCF.

[0299] Specifically, the AF sends a first message to one or more PCFs directly or through the NEF to request the energy consumption information and / or energy efficiency information of the DNAI. The first message carries one or more DNAIs, which are used to indicate the request / subscription network access to the energy consumption information and / or energy efficiency information of the specified DNAI; or carries a DNN, which is used to indicate the request / subscription network access to the energy consumption information and / or energy efficiency information of one or more DNAIs of the DNN.

[0300] The PCF replies / reports the energy consumption information and / or energy efficiency information of the network access DNAI to the AF.

[0301] Specifically, if the PCF receives the first message from the AF, the PCF may request / subscribe to the energy consumption information and / or energy efficiency information of the corresponding DNAI from the SMF, and then reply / report the energy consumption information and / or energy efficiency information of the network access DNAI to the AF based on the reply / report of the SMF. If the SMF receives a request for energy consumption information and / or energy efficiency information of the DNAI from the AF or PCF, the SMF may request / subscribe to the energy consumption information and / or energy efficiency information of the corresponding DNAI from the UPF, and then reply / report the energy consumption information and / or energy efficiency information of the network access DNAI to the AF based on the reply / report of the UPF and the energy consumption information and / or energy efficiency information of the SMF serving the DNAI.

[0302] Step 31f: The AF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with the UE.

[0303] Specifically, the AF sends a first message to the UE through the user plane (or application layer) to request energy consumption information and / or energy efficiency information of at least one DNAI. The first message carries one or more DNAIs for indicating the request / subscription of the energy consumption information and / or energy efficiency information of the UE accessing the specified DNAI; or carries a DNN for indicating the request / subscription of the energy consumption information and / or energy efficiency information of one or more DNAIs of the DNN. The UE determines the energy consumption information and / or energy efficiency information of the UE accessing the specified DNAI based on the energy consumption information and / or energy efficiency information of the UE currently accessing the specified DNAI, or the statistical information of the energy consumption and / or energy efficiency of the previous access to the specified DNAI or the predicted information of the energy consumption and / or energy efficiency of the future access to the specified DNAI, and sends it to the AF through the user plane (or application layer).

[0304] Step 31g: AF obtains analysis information of energy consumption and / or energy efficiency of at least one DNAI by interacting with NWDAF.

[0305] Step 32: The AF determines whether the DNAI list of the specified application needs to be updated based on the acquired DNAI energy consumption information and / or energy efficiency information.

[0306] Step 33: If the DNAI list needs to be updated, obtain the updated DNAI list;

[0307] Specifically, AF determines a list of DNAIs that support a specified application with low energy consumption and / or high energy efficiency based on the energy consumption information and / or energy efficiency information of the DNAI that supports the application, which includes one or more DNAIs; or, determines a list of DNAIs that support the application and the energy consumption information and / or energy efficiency information of each DNAI therein.

[0308] Step 34: The AF sends an application request to the PCF directly or through the NEF (or Unified Data Repository (UDR)).

[0309] In some embodiments, the application request carries an updated DNAI list, or the updated DNAI list and energy consumption information and / or energy efficiency information corresponding to each DNAI in the DNAI list, such as energy consumption level and / or energy efficiency level.

[0310] Step 35: PCF sends a session management (SM) policy update notification to SMF, and includes the received DNAI list in the session management (SM) policy and sends it to SMF.

[0311] Step 36. SMF, based on the received DNAI list, gives priority to using DNAIs with low energy consumption or high energy efficiency in the DNAI list when establishing a PDU session, or when changing or adding a PDU session anchor point UPF after the PDU session is established, and does not use DNAIs with high energy consumption or low energy efficiency (for example: deleting the PDU session anchor point UPF connected to the DNAI).

[0312] It should be noted that for the scenario where the PDU session anchor point UPF is changed or added after the PDU session is established, SMF selects a new PSA UPF and (optional) UL CL / BP UPF for the PDU session based on the selected new DNAI with low energy consumption or high energy efficiency.

[0313] In some embodiments, if a new PDU session needs to be established to access a new DNAI (i.e., target DNAI), the SMF provides the selected new DNAI with low energy consumption or high energy efficiency to the AMF. The AMF selects a new SMF based on the new DNAI and provides the new DNAI to the SMF. The new SMF selects a new PSA UPF and (optionally) UL CL / BP UPF for the PDU session based on the new DNAI.

[0314] Application Scenario 2: The first network function is NEF

[0315] As shown in Figure 4, the specific implementation process includes:

[0316] Step 41: AF sends an application request to NEF;

[0317] Among them, the application request carries AF identifier and AF service identifier, application identifier or service filtering information (traffic filtering information), UE address, UE identifier or UE group identifier, DNN, DNAI list (including one or more DNAIs), S-NSSAI and other information to guide the transmission of application / service.

[0318] Step 42: The NEF obtains first information of at least one data network access point.

[0319] Specifically, the NEF obtains energy consumption information and / or energy efficiency information of at least one DNAI from a network function (e.g., NEMF, PCF, SMF, or UPF), or obtains analytical information (e.g., statistical information or prediction information) of energy consumption and / or energy efficiency of at least one DNAI from the NWDAF;

[0320] It should be noted that NEF obtains the energy consumption information and / or energy efficiency information of DNAI from NF (such as NEMF, PCF, SMF or UPF) based on the DNAI list or DNN carried in the AF request, or if the AF request does not carry the DNAI list, NEF obtains the analysis information of DNAI's energy consumption and / or energy efficiency from NWDAF based on the DNAI list or DNN obtained by mapping the AF service identifier.

[0321] Specifically, it may include one of the following steps:

[0322] Step 42a: NEF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with NEMF.

[0323] Step 42b: The NEF obtains energy consumption information and / or energy efficiency information of at least one DNAI by interacting with the UPF.

[0324] Specifically, NEF selects one or more UPFs that can access or serve the DNAI (or DNN) based on the determined DNAI (or DNN), and sends a first message to the selected UPF to request the energy consumption information and / or energy efficiency information of the DNAI. The first message carries a DNAI in the DNAI list received or mapped from the AF, which is used to indicate the energy consumption information and / or energy efficiency information of the specified DNAI for requesting / subscribing to network access; or carries a DNN received or mapped from the AF, which is used to indicate the energy consumption information and / or energy efficiency information of one or more DNAIs for requesting / subscribing to network access to the DNN.

Specifically, UPF receives the request for energy consumption information and / or energy efficiency information of DNAI from SMF, measures the energy consumption / energy efficiency of local transmission of service data to the specified DNAI, or obtains the energy consumption and / or energy consumption analysis information of the specified DNAI from NWDAF, thereby obtaining the energy consumption information and / or energy efficiency information of accessing the specified DNAI, and replies / reports the information to SMF.

[0372] Step 63d: SMF obtains analysis information of energy consumption and / or energy efficiency of at least one DNAI by interacting with NWDAF.

[0373] Step 64: SMF determines the target DNAI;

[0374] Specifically, based on energy consumption information and / or energy efficiency information, SMF gives priority to using DNAI with low energy consumption or high energy efficiency when establishing a PDU session, or when changing or adding the PDU session anchor point UPF after the PDU session is established, and does not use DNAI with high energy consumption or low energy efficiency (for example: deleting the PDU session anchor point UPF connected to the DNAI).

[0375] Step 65: For the scenario where the PDU session anchor point UPF is changed or added after the PDU session is established, the SMF selects a new PSA UPF and (optional) UL CL / BP UPF for the PDU session based on the selected new DNAI with low energy consumption or high energy efficiency.

[0376] Application Scenario 5: Obtaining energy efficiency and / or energy efficiency analysis information (e.g., statistical information or forecast information) from NWDAF

If the output analysis information is for a specific PDU session, the analysis information in Table 3 does not include the average energy consumption information per PDU session and the average renewable energy consumption information per PDU session. If the output analysis information is for a specific service / application, the analysis information in Table 3 does not include the average energy consumption information per service / application and the average renewable energy consumption information per service / application.
