[0051] The 3GPP (3rd Generation Partnership Project) OAM (Operational Information Management) side already supports some energy efficiency and energy saving scenarios and functions. These functions aim to reduce the energy consumption of network equipment and improve overall energy efficiency through intelligent management and optimization.
[0052] In related technologies, the network management side can collect and statistically analyze energy-saving KPIs, but it is difficult to bill session-level energy consumption information.
[0053] This disclosure provides a communication method and apparatus, and a computer-readable storage medium, which enables billing of session-level energy consumption information of user equipment.
[0054] Figure 1 shows a flowchart of a communication method according to some embodiments of the present disclosure.
[0055] As shown in Figure 1, the communication method includes steps S11-S13. In some embodiments, the communication method is performed by a wireless access network node.
[0056] In step S11, a request from the SMF to obtain energy consumption information of the target PDU session is received.
[0057] In some embodiments, receiving a request from the SMF to obtain energy consumption information of a target PDU session includes: receiving a request from the SMF to obtain energy consumption information of a target PDU session through the Access and Mobility Management Function (AMF).
[0058] For example, in the PDU session establishment process, the SMF requests a PDU session-level energy consumption report from the RAN through the AMF.
[0059] In step S12, the energy consumption information of the target PDU session is determined based on the data volume of the target PDU session in the radio access network node, the total data volume of the radio access network node, and the total energy consumption.
[0060] In some embodiments, the energy consumption information of the target PDU session is determined based on the data volume of the target PDU session in the radio access network node, the total data volume of the radio access network node, and the total energy consumption: the energy consumption of the target PDU session is determined based on the ratio of the data volume of the target PDU session in the radio access network node to the total data volume of the radio access network node and the total energy consumption of the radio access network node.
[0061] For example, first calculate the ratio of the data volume of the target PDU session at the radio access network node to the total data volume of the radio access network node, and then calculate the product of the ratio and the total energy consumption of the radio access network node to obtain the energy consumption of the target PDU session.
[0062] For example, RAN is calculated according to the formula DV. PDUsession / DV RAN *EC RAN Estimate the power consumption of the PDU session level, where DV PDUsession DV represents the data volume of the target PDU session on this node. RAN EC represents the total amount of data for this node. RAN This represents the total energy consumption of the node. The network management side supports statistical energy consumption EC. RAN .
[0063] In step S13, the energy consumption information of the target PDU session is sent to the SMF for billing user equipment.
[0064] In some embodiments, the energy consumption information includes the energy consumption of the target PDU session, and may further include the identifier of the target PDU session and / or the start and end times corresponding to the energy consumption of the target PDU session.
[0065] For example, the RAN generates an energy consumption report at the target PDU session level. This report includes the target PDU session ID, the energy consumption of the target PDU session, the time when energy consumption statistics for the target PDU session started, and the time when energy consumption statistics for the target PDU session ended. The time is recorded, for example, as a timestamp. The RAN then sends the energy consumption report (including energy consumption information) to the SMF.
[0066] The RAN returns a session-level energy consumption report for the target PDU, which includes information such as the start and end timestamps of the statistics.
[0067] In some embodiments, sending the energy consumption information of the target PDU session to the SMF for billing the target PDU session includes: sending the energy consumption information of the target PDU session to the SMF via the AMF for billing the user equipment.
[0068] For example, the RAN sends the energy consumption information of the target PDU session to the AMF, and the AMF sends the energy consumption information of the target PDU session to the SMF.
[0069] In some embodiments, the communication method further includes: receiving a request from the SMF to obtain energy consumption information of a target QoS stream; determining the energy consumption information of the target QoS stream based on the data volume of the target QoS stream at the radio access network node, the total data volume of the radio access network node, and the total energy consumption; and sending the energy consumption information of the target QoS stream to the SMF for billing of user equipment.
[0070] For example, a similar approach to billing target PDU sessions can be used to bill energy consumption information at the QoS flow level.
[0071] In some embodiments, the energy consumption of the target QoS flow is determined based on the ratio of the data volume of the target QoS flow at the radio access network node to the total data volume of the radio access network node and the total energy consumption of the radio access network node.
[0072] For example, RAN is calculated according to the formula DV. QoS flow / DV RAN *EC RAN Estimate the power consumption of the PDU session level, where DV QoS flow DV represents the data volume of the target QoS stream on this node. RAN EC represents the total amount of data for this node. RAN This represents the total energy consumption of the node. The network management side supports statistical energy consumption EC. RAN .
[0073] A communication method applied to a wireless access network node according to some embodiments of the present disclosure includes: receiving a request from a session management function (SMF) to obtain energy consumption information of a target protocol data unit (PDU) session; determining the energy consumption information of the target PDU session based on the data volume of the target PDU session in the wireless access network node, the total data volume of the wireless access network node, and the total energy consumption; and sending the energy consumption information of the target PDU session to the SMF for billing user equipment, thereby realizing the statistics and billing of session-level energy consumption information.
[0074] Figure 2 shows a flowchart of a communication method according to some other embodiments of the present disclosure.
[0075] As shown in Figure 2, the communication method includes steps S21-S23. In some embodiments, the communication method is performed by the SMF.
[0076] In step S21, the power consumption information of the target protocol data unit (PDU) session is requested from the radio access network node.
[0077] In step S22, energy consumption information of the target PDU session is received from the radio access network node. The energy consumption information is determined based on the data volume of the target PDU session in the radio access network node, the total data volume of the radio access network node, and the total energy consumption.
[0078] Energy consumption information may include, for example, the energy consumption of the target PDU session, and may also include the identifier of the target PDU session and / or the start and end times corresponding to the energy consumption of the target PDU session.
[0079] In step S23, a billing request for the user equipment is sent to the billing function CHF based on the energy consumption information of the target PDU session.
[0080] For example, the CTF embedded in the SMF sends a billing data request to the CHF based on the received energy consumption information.
[0081] Figure 3 illustrates a 5G data connection converged billing architecture according to some embodiments of the present disclosure.
[0082] CTF is a functional module embedded in all billing-related network elements. Its main function is to collect billing information about the UE's use of network resources within the network element to facilitate subsequent billing and billing generation. As shown in Figure 3, the SMF embeds CTF and generates billing events for CHF, which are used for data connection convergence billing.
[0083] The CHF receives NG-RAN energy consumption information from the SMF as a CDR. The CHF then activates the CDR for the PDU session and responds to the billing request. The CDR related to the PDU session can subsequently be used by the operator for energy-saving billing, providing billing discounts for energy-saving users, etc.
[0084] In some embodiments, the billing request includes the energy consumption of the target PDU session, and the billing request may also include the identifier of the target PDU session and / or the start and end times corresponding to the energy consumption of the target PDU session.
[0085] In some embodiments, the communication method further includes requesting energy consumption information of a target QoS stream from a radio access network node; receiving energy consumption information of the target QoS stream from the radio access network node, wherein the energy consumption information is determined based on the data volume of the target QoS stream at the radio access network node, the total data volume of the radio access network node, and the total energy consumption; and sending a billing request for the user equipment to the CHF based on the energy consumption information of the target QoS stream.
[0086] For example, a similar method to billing target PDU sessions can be used to bill energy consumption information at the QoS flow level.
[0087] Figure 4 shows an interaction diagram of a communication method according to some embodiments of the present disclosure.
[0088] As shown in Figure 4, the communication method includes events 101-107.
[0089] Event 101: During the PDU session establishment process, the SMF requests a PDU session-level energy consumption report from the RAN through the AMF. For example, the SMF sends an energy consumption information retrieval request (Nsmf_EnergyInfo Request) to the AMF.
[0090] In Event 102, the AMF forwarded the NG-RAN Energy Info request to the RAN.
[0091] In Event 103, the RAN estimates the session-level energy consumption of the PDU based on the formula DVPDUsession / DVRAN*ECRAN. The RAN returns session-level energy consumption information for the target PDU, which may be in the form of an NG-RAN Energy Info Report, including information such as the start and end timestamps of the statistics.
[0092] In event 104, the AMF forwarded the report (Nsmf_EnergyInfo Report) to the SMF.
[0093] In Event 105, the CTF embedded in the SMF sends a Charging Data Request to the CHF based on the received energy consumption report.
[0094] Event 106: CHF receives NG-RAN energy consumption information report from SMF as CDR, and CHF enables CDR for this PDU session.
[0095] In event 107, CHF responds to the billing request, for example, by sending a charging data response to SMF.
