[0047] The technical solutions of the present disclosure are described in further detail below with reference to the accompanying drawings and embodiments.

[0048] The inventor found that there is no new network architecture of network element design capable of providing computing power management and orchestration function in the current core network, and the mobile communication network lacks computing power scheduling and management capability of computing power nodes, which affects the computing power scheduling capability of the mobile communication network.

[0049] To solve the above problems, the disclosure provides a computing power management and arrangement method, a functional entity, a storage medium and a network system, which can improve the computing power management and arrangement capability in the mobile network and improve the ability to meet the user computing power demand.

[0050] The flowchart of some embodiments of the computing power management and arrangement method of the disclosure is shown in Figure 1

[0051] In step S11, the CMOF entity creates a computing power service instance according to the user computing power demand information and generates a computing power arrangement task.

[0052] In some embodiments, the user computing power demand information includes UE identifier, PDU session identifier, PDU session type, computing power demand type, computing power resource size demand, radio access network (RAN) GTP-U tunnel endpoint information, and user plane function (UPF) GTP-U tunnel endpoint information. The user computing power demand information can also be supplemented or adjusted according to user demand. Such user computing power demand information can realize the transmission of user demand and improve the satisfaction of the generated computing power service instance to user demand.

[0053] In some embodiments, the CMOF entity can obtain the user computing power demand information from the CPCF entity. The CPCF entity can generate and send the user computing power demand information to the CMOF entity in the case of determining that the UE generates computing power demand, and the network element interaction unit obtains the user computing power demand information from the CPCF entity, so as to realize that the core network triggers the CMOF entity to perform computing power arrangement according to user demand, improve the computing power management and arrangement capability in the mobile network, and improve the satisfaction capability to user computing power demand. In step S12, the CMOF entity stores the computing power service instance and monitors the state of the computing power service instance.

[0054] In step S13, the CMOF entity determines the computing power node for executing the computing power task according to the computing power arrangement task and schedules the computing power node. In some embodiments, the computing power node can be scheduled according to the computing power service identifier, the computing power demand type and the computing power resource size demand.

[0055] In some embodiments, the above steps can be realized by the respective units of the CMOF entity according to the embodiments of the CMOF entity shown in Figure 3

[0056] Based on the method in the above embodiments, the CMOF entity can utilize the functions of each unit itself and the mutual interaction between the units to play the role of a bridge and hub between the mobile communication network and the computing power node, complete the computing power management and arrangement function in the mobile computing power network scenario, arrange and schedule the computing power according to the user demand, improve the satisfaction capability of the mobile network to the user computing power demand, and improve the user friendliness.​​

[0057] In some embodiments, before step S11, the computing power management and orchestration method of the present disclosure can further include: the CMOF entity receiving computing power resource change subscription information from the CPCF entity, and establishing a long connection with the CPCF entity. After completing the computing power resource change subscription, the network element interaction unit 101 reports to the CPCF entity in a timely manner according to the monitored computing power resource change situation, by using the long connection, so that the core network side can learn about the computing power resource change situation in a timely manner, and the understanding degree of the mobile network for the network computing power resource is improved, thereby facilitating timely adjustment.

[0058] In some embodiments, in step S11, after receiving the user computing power demand information, the CPCF entity compares the state information timestamp of the CPCF entity with the state information timestamp of the entity, and in the case that the comparison result is the same, creates a computing power service instance, and sends a computing power orchestration task to the service orchestration unit, thereby executing computing power orchestration in the case of ensuring time synchronization between entities, so as to reduce unnecessary consumption of computing power resources. In some embodiments, if the timestamps are different, it is presumed that there is a delay or a failure, and feedback is given on orchestration failure or abnormal information, so as to timely recover from the failure.

[0059] In some embodiments, after step S63, the computing power management and orchestration method of the present disclosure can further include feeding back the computing power demand satisfaction situation to the source node (such as the CPCF entity) of the user computing power demand information, thereby facilitating the core network side to determine that the computing power scheduling for the user computing power demand has been completed, and improving the reliability of the computing power service. In some embodiments, the service orchestration unit of the CMOF entity can feed back the computing power resource scheduling situation to the network element interaction unit, and the network element interaction unit feeds back the computing power demand satisfaction situation to the source node (such as the CPCF entity) of the user computing power demand information according to the computing power resource scheduling situation, thereby realizing message transmission by using the functions of different units and the interaction process between the units.

[0060] The flowchart of another embodiment of the computing power management and orchestration method of the present disclosure is shown in Figure 2

[0061] In step S21, the CMOF entity acquires a computing power demand update message.

[0062] In step S22, the CMOF entity determines whether there is a computing power service instance corresponding to the computing power demand update message. If there is a computing power service instance corresponding to the computing power demand update message, step S23 is executed. In some embodiments, if there is no computing power service instance corresponding to the computing power demand update message, abnormal information can be fed back, so that the core network side can verify and send the computing power demand update message to other CMOF entities.

[0063] ​In step S23, the CMOF entity updates the corresponding computing power service instance according to the computing power demand update message, monitors the state of the computing power service instance, and generates a computing power update task.

[0064] In step S24, the CMOF entity updates the computing power nodes of the computing power task according to the computing power update task, and updates the scheduled computing power nodes.

[0065] In some embodiments, the above steps can be implemented by various units of the CMOF entity in cooperation with each other according to the embodiments of the CMOF entity as shown below (such as Figure 3 ).

[0066] Through the method in the above embodiments, the change of demand can be timely responded to, and the existing computing power service instance can be adjusted, so as to improve the satisfaction of user demand while avoiding the waste of computing power resources caused by the re-creation of a computing power service instance, and improve the effective utilization rate of computing power resources.

[0067] In some embodiments, after receiving the computing power demand update message, the CMOF entity can compare the state information timestamp of the computing power policy control function entity with the state information timestamp of the CMOF entity through the long connection between the CMOF entity and the CPCF entity, and in the case that the comparison result is the same, perform the operation of sending the computing power demand update message to the computing power instance library in the case that it is determined that the computing power service instance corresponding to the computing power demand update message exists in the computing power instance library, so as to perform computing power arrangement in the case of ensuring the time synchronization between entities, so as to reduce unnecessary consumption of computing power resources. In some embodiments, if the timestamps are different, it is presumed that there is a delay or a failure, and feedback arrangement failure or abnormal information is fed back in order to timely recover from the failure.

[0068] A schematic diagram of some embodiments of the CMOF entity of the present disclosure is shown in Figure 3 In some embodiments, the CMOF entity includes a network element interaction unit 101, a computing power instance library 102, a data analysis event triggering unit 103, and a service arrangement unit 104. The various units of the CMOF entity realize the management and arrangement of computing power through their own functions and mutual interaction.

[0069] The network element interaction unit 101 can create a computing power service instance according to user computing power demand information, and send a computing power arrangement task to the service arrangement unit. In some embodiments, the above-mentioned user computing power demand information comes from a CPCF entity on the core network side. The CPCF entity can generate and send user computing power demand information to a CMOF entity in the case of determining that a UE has a computing power demand, and the network element interaction unit obtains the user computing power demand information from the CPCF entity, thereby realizing that the core network triggers the CMOF entity to perform computing power arrangement according to user demand, improving the computing power management and arrangement capability in the mobile network, and improving the satisfaction capability for user computing power demand.

[0070] In some embodiments, the user computing power demand information includes a UE identifier, a PDU session identifier, a PDU session type, a computing power demand type, a computing power resource size demand, radio access network (RAN) GTP-U tunnel endpoint information, and user plane function (UPF) GTP-U tunnel endpoint information. The user computing power demand information can also be supplemented or adjusted according to user demand. Such user computing power demand information can realize the transmission of user demand and improve the satisfaction degree of the generated computing power service instance for user demand.

[0071] The computing power instance library 102 can store computing power service instances from the network interaction unit, and trigger the data analysis event triggering unit 103.

[0072] The data analysis event triggering unit 103 can monitor the state of the computing power service instance under the triggering of the computing power instance library 102.

[0073] The service arrangement unit 104 can determine a computing power node for executing a computing power task and schedule the computing power node according to a computing power arrangement task from the network element interaction unit 101. In some embodiments, the service arrangement unit can schedule the computing power node according to a computing power service identifier, a computing power demand type, and a computing power resource size demand.

[0074] Based on the CMOF entity in the above-mentioned embodiments, each unit can utilize its own functions and mutual interaction between units to play a role as a bridge and hub between a mobile communication network and a computing power node, and complete the computing power management and arrangement function in a mobile computing power network scenario; arrange and schedule computing power according to user demand, improve the satisfaction capability of the mobile network for user computing power demand, and improve user friendliness.

[0075] In some embodiments, the network element interaction unit 101 can also receive the computing power resource change subscription information from the CPCF entity after going online, and establish a long connection with the CPCF entity. When the computing power resource change subscription is completed, the network element interaction unit 101 reports to the CPCF entity in a timely manner according to the monitored computing power resource change situation, so that the core network side can learn about the computing power resource change situation in a timely manner, and the understanding of the network computing power resource by the mobile network is improved, thereby facilitating timely adjustment.

[0076] In some embodiments, after receiving the user computing power demand information, the network element interaction unit 101 can compare the state information timestamp of the CPCF entity with the state information timestamp of the entity through the long connection. If the comparison result is the same, the network element interaction unit 101 creates a computing power service instance and sends a computing power arrangement task to the service arrangement unit, thereby performing computing power arrangement under the condition of ensuring time synchronization between entities, so as to reduce unnecessary consumption of computing power resources. In some embodiments, if the timestamps are different, it is presumed that a delay or a failure occurs, and arrangement failure or abnormal information is fed back, so that fault recovery can be performed in a timely manner.

[0077] In some embodiments, the service arrangement unit 104 can also feed back the computing power resource scheduling situation to the network element interaction unit 101 after completing the scheduling of the computing power node. The network element interaction unit 101 can also feed back the computing power demand satisfaction situation to the source node (such as the CPCF entity) of the user computing power demand information according to the computing power resource scheduling situation, so that the core network side can determine that the computing power scheduling for the user computing power demand has been completed, and the reliability of the computing power service is improved.

[0078] In some embodiments, when generating the computing power service instance, the network element interaction unit 101 can generate an identifier (such as a computing power service instance ID) of the computing power service instance, and send the identifier of the computing power service instance and the user computing power demand information to the computing power instance library. The computing power arrangement task generated by the network element interaction unit 101 and sent to the service arrangement unit 104 includes the identifier of the computing power service instance and the user computing power demand information. Such a CMOF entity can record and schedule the computing power service instance by taking the identifier of the computing power service instance as an index, which is conducive to subsequent query and use, and avoids confusion. In some embodiments, the service arrangement unit 104 can use the information in the user computing power demand information, such as PDU session related information, to arrange the computing power resources, thereby improving the reliability of the computing power resource arrangement.

[0079] The CMOF entity in the above embodiments of the present disclosure can implement the new creation of the computing power service. In some embodiments, the signaling flowchart of the CMOF entity 10 of the present disclosure in the process of creating a computing power instance is as shown in Figure 4

[0080] ​In some embodiments, the network element interaction network element 101 can interact with the CPCF network element to complete the computing power resource state real-time reporting function; can receive the user computing power new creation demand and the modification demand transmitted by the CPCF network element, create the computing power service instance, issue the computing power service instance to the service arrangement unit, and create the computing power service instance in the computing power instance library; can receive the computing power service information fed back by the service arrangement unit, and perform computing power service feedback and interaction with the core network CPCF network element.

[0081] In some embodiments, the data analysis event triggering unit 103 can perform real-time monitoring and analysis on the computing power service instance, generate corresponding events based on the latest computing power demand of the user, and trigger the service arrangement task of the service arrangement unit.

[0082] In some embodiments, the service arrangement unit 104 can receive the computing power scheduling demand from the network element interaction unit and the data analysis event triggering unit, and complete the computing power resource scheduling in cooperation with the computing power node; can feed back the computing power resource scheduling situation to the network element interaction unit.

[0083] In some embodiments, the computing power instance library 102 can store the computing power service instance.

[0084] In step 401, the CPCF entity 21 obtains the current computing power resource information from the CMOF entity 10 in a subscription mode.

[0085] In step 402, the CPCF entity 21 requests to establish a long connection with the CMOF entity 10.

[0086] In step 403, after the long connection is established, the CMOF entity 10 reports the computing power resource change to the CPCF entity 21. In some embodiments, the computing power state information provided by the CMOF entity 10 includes but is not limited to the DNAI (Data Network Access Identifier) of the target computing power node, the IP address of the target computing power node, and the number of available computing power units.

[0087] In step 404, the computing power demand of the UE is sent to the network element interaction network element 101 in the CMOF entity 10 through the CPCF entity 21, and the CPCF entity 21 sends the user computing power demand information to the CMOF entity 10. In some embodiments, the user computing power demand information includes but is not limited to the UE ID, the PDU session ID, the PDU session type, the computing power demand type, the computing power resource size demand, the RAN GTP-U tunnel endpoint information, and the UPF GTP-U tunnel endpoint information.

[0088] In step 405, the network element interaction unit 101 in the CMOF entity 10 creates a computing power service instance according to the requirements of the CPCF entity 21, and generates a computing power service instance ID. Through the long connection of both parties, the CMOF entity 10 acquires the state information timestamp of the CPCF entity and compares them. If the state information timestamps of the CMOF and the CPCF are consistent, the next step is performed.

[0089] In step 406, the computing power instance library 102 in the CMOF entity 10 receives the computing power service instance related information sent by the network element interaction unit 101, completes the creation of the computing power service instance, and stores the computing power service instance ID and the related information (such as user computing power requirement information or part of the information) sent by the CPCF entity.

[0090] In step 407, the data analysis event triggering unit 103 in the CMOF entity 10 monitors the state of the computing power service instance.

[0091] In step 408, the network element interaction unit 101 sends a computing power orchestration task to the service orchestration unit 104, and the task contains the computing power service instance ID and the related information (such as user computing power requirement information or part of the information) sent by the CPCF.

[0092] In step 409, the service orchestration unit 104 analyzes the PDU session related information sent by the CPCF, determines the related computing power nodes for executing the computing power task, and completes the computing power resource scheduling for the computing power nodes 22 according to the computing power service ID, the computing power requirement type, and the computing power resource size requirement.

[0093] In step 410, the service orchestration unit 104 feeds back the computing power resource scheduling situation to the network element interaction unit 101.

[0094] In step 411, the network element interaction unit 101 of the CMOF network element 101 sends the computing power requirement satisfaction situation to the core network CPCF entity 21.

[0095] Based on the CMOF network element shown in the above embodiments, the reaction reliability and speed of the computing power nodes to user and core network requirements can be improved, and the ability and efficiency of mobile network computing power orchestration and scheduling can be improved.

[0096] In some embodiments, the CMOF entity can also update the existing computing power service instance for the modification of the computing power requirement.

[0097] The network element interaction unit 101 can also obtain a computing power demand update message, and in a case where it is determined that the computing power service instance corresponding to the computing power demand update message exists in the computing power instance library, send the computing power demand update message to the computing power instance library. In some embodiments, the computing power demand update message is from a CPCF entity. In some embodiments, the UE passes the demand for computing power demand update to the network element interaction unit 101 via the CPCF entity.

[0098] In some embodiments, the computing power demand update message includes a computing power service instance identifier, a UE identifier, an original PDU session identifier, an original PDU session type, a new PDU session identifier, a new PDU session type, an original computing power demand type, an original computing power resource size demand, a new computing power demand type, a new computing power resource size demand, original RAN GTP-U tunnel endpoint information, original UPF tunnel endpoint information, new RAN tunnel endpoint information, and new UPF tunnel endpoint information. In some embodiments, the original PDU session identifier, the original PDU session type, the original computing power demand type, the original computing power resource size demand, the original RAN GTP-U tunnel endpoint information, and the original UPF tunnel endpoint information can be determined in the last computing power demand update for the same computing power service instance; in a case where no update occurs to the computing power service instance, the computing power service instance is determined through a computing power service creation process. In some embodiments, the new PDU session identifier, the new PDU session type, the new computing power demand type, the new computing power resource size demand, the new RAN tunnel endpoint information, and the new UPF tunnel endpoint information are determined according to the current computing power demand update message.

[0099] In some embodiments, the CMOF entity and the CPCF entity have a long connection, and the network element interaction unit can compare the state information timestamp of the computing power policy control function entity with the state information timestamp of the CMOF entity after receiving the computing power demand update message, and in a case where the comparison result is the same, perform the operation of sending the computing power demand update message to the computing power instance library in a case where it is determined that the computing power service instance corresponding to the computing power demand update message exists in the computing power instance library, thereby performing computing power orchestration in the case of ensuring time synchronization between entities to reduce unnecessary consumption of computing power resources. In some embodiments, if the timestamps are different, it is presumed that a delay or a failure has occurred, and feedback is given to orchestration failure or abnormal information in order to promptly recover from the failure.

[0100] The computing power instance library 102 can also update the corresponding computing power service instance according to the computing power demand update message, and trigger the data analysis event triggering unit.

[0101] The data analysis event triggering unit 103 can also monitor the state of the computing power service instance under the triggering of the computing power instance library 102, and generate a computing power update task and send it to the service orchestration unit 104.

[0102] The service orchestration unit 104 can also update the computing power node of the computing power task according to the computing power update task, and update the scheduling computing power node.

[0103] Based on the CMOF network element shown in the above embodiments, the demand change situation can be timely responded to, the existing computing power service instance is adjusted, thereby improving the satisfaction of user demand, avoiding the waste of computing power resources caused by the re-creation of the computing power service instance, and improving the effective utilization rate of the computing power resources.

[0104] In some embodiments, the signaling flowchart of the CMOF entity in the process of updating the computing power instance is as shown in Figure 5 .

[0105] In step 500, based on the completed message subscription of the CPCF entity to the CMOF entity and the long connection between the two, the CMOF entity 10 reports the computing power resource change to the CPCF entity 21. In some embodiments, the reporting can be periodic to reduce the reporting pressure.

[0106] In step 501, the UE that has established a computing power service instance sends a computing power demand update message to the network element interaction unit 101 in the CMOF entity 10 through the CPCF entity 21, and the information carried by the computing power demand update message includes but is not limited to the identification of the computing power service instance (such as the computing power service instance ID), the UE ID, the original PDU session ID, the original PDU session type, the new PDU session ID, the new PDU session type, the original computing power demand type, the original computing power resource size demand, the new computing power demand type, the new computing power resource size demand, the original RAN GTP-U tunnel termination point information, the original UPF GTP-U tunnel termination point information, the new RAN GTP-U tunnel termination point information, and the new UPF GTP-U tunnel termination point information.

[0107] In step 502, the network element interaction unit 101 in the CMOF entity 10 queries whether there is a corresponding computing power service instance in the computing power instance library 102 according to the identification of the computing power service instance in the obtained computing power demand update message. At the same time, the state information timestamp of the CPCF is obtained through the long connection between the two, and if the state information timestamps of the CMOF entity 10 and the CPCF entity 21 are consistent, the computing power demand update message is sent to the computing power instance library 102.

[0108] In step 503, the computing power instance library 102 completes the modification of the computing power service instance corresponding to the identification of the computing power service instance.

[0109] In step 504, the data analysis event triggering unit 103 in the CMOF entity 10 monitors the computing power service instance state.

[0110] In step 505, the data analysis event triggering unit 103 in the CMOF entity 10 generates a computing power update event.

[0111] In step 506, the data analysis event triggering unit 103 in the CMOF entity sends a computing power update orchestration task to the service orchestration unit 104. The computing power update orchestration task contains the identification of the computing power service instance and the computing power update related information sent by the CPCF (such as all or part of the information in the computing power demand update message).

[0112] In step 507, the service orchestration unit 104 parses the computing power update related information sent by the CPCF entity 21, and determines the relevant computing power nodes of the update computing power task according to the original PDU session related information (which can be obtained through the last computing power demand update message for the same computing power service instance, or through the user computing power demand information in the case of no update) and the new PDU session related information. The update scheduling of computing power resources is completed according to the original computing power demand related information and the new computing power demand related information.

[0113] In step 508, the service orchestration unit 104 feeds back the computing power resource scheduling update situation.

[0114] In step 509, the network element interaction unit 101 of the CMOF entity 10 sends the satisfaction of the computing power update demand to the core network CPCF entity 21.

[0115] Based on the CMOF network element shown in the above embodiment, the user computing power demand change situation can be timely responded, and the user computing power guarantee capability can be improved.
