Mobile network communication systems supporting computing services include computing nodes. Terminals can act as sending nodes, receiving nodes, or computing nodes for computing services, while access network devices serve the terminals and participate in the computing services. In related technologies, the access network devices serving the terminals transmit data for computing tasks until the computing nodes complete the computing tasks. However, during the execution of computing tasks by the computing nodes, the access network devices may fail to transmit the computing task data effectively (e.g., changes in the terminal's location may degrade communication quality, failing to meet computing demands), resulting in poor computing service performance.

[0092] For ease of understanding, the following explains some aspects of the embodiments of this application:

[0093] 1. Switch

[0094] Handover is triggered by the movement of User Equipment (UE, i.e., terminal) while in a connected state. The basic goal of handover is:

[0095] It instructs the UE to communicate with a cell that has better channel quality than the current serving cell; it provides the UE with continuous, uninterrupted communication service, effectively preventing dropped calls due to deteriorating cell signal quality. The handover process in 5G includes the following steps:

[0096] (1) Triggering Measurement: After the UE completes access or successfully hands over, the gNodeB will send measurement control information to the UE via RRC Connection Reconfiguration. Furthermore, if the measurement configuration information is updated, the gNodeB will also send updated measurement control information via Radio Resource Control (RRC) Connection Reconfiguration messages. The most important information in the measurement control message includes the measurement object, Measurement Report (MR) configuration, and measurement events.

[0097] The measurement events defined by 3GPP for NR (with the addition of A6 compared to LTE) are shown in Table 1.

[0098] Table 1

[0099] The specific criteria for determining 5G measurement events are shown in Table 2.

[0100] Table 2

[0101] in:

[0102] Ms represents the measurement results of the serving cell;

[0103] Mn represents the measurement results of the neighboring cell;

[0104] TimeToTrig represents the duration for which the event entry condition is continuously met, i.e., time delay;

[0105] Off indicates the bias of the measurement result, with a step size of 0.5 dB;

[0106] Hys indicates the amplitude hysteresis of the measurement result, with a step size of 0.5 dB;

[0107] Ofs represents the frequency offset of the serving cell;

[0108] Ofn represents the frequency offset of the neighboring cell;

[0109] Ocs stands for Cell Individual Offset (CIO).

[0110] Ocn represents the cell-specific bias CIO of neighboring cells within the system;

[0111] Thresh corresponds to the threshold value configured for the event.

[0112] The measured event values ​​are shown in Table 3.

[0113] Table 3

[0114] The event value range in 5G NR differs from that in LTE. Range corresponds to the value reported in the measurement report, while Value corresponds to its actual value. Taking Reference Signal Received Power (RSRP) as an example, the Value range in LTE is -140 to -44 dBm, while in NR it is -156 to -31 dBm. NR allows for higher and lower receive levels. The actual value in LTE is -140 (MR report value), while in NR it is -156 (MR report value). Assuming the RSRP reported in MR is 50, the actual value is 50 - 140 = -90 dBm. However, the actual RSRP value in NR is 50 - 156 = -106 dBm.

[0115] (2) Perform measurement: According to the relevant configuration of measurement control, the UE monitors the radio channel, but when the measurement reporting conditions (A1-A6, B1 and B2) are met, it reports to the gNB through an event. The number of measurement reports / events can be triggered by RSRP, Reference Signal Received Quality (RSRQ) or Signal-to-noise and interference ratio (SINR).

[0116] (3) Target decision: The gNB selects the handover cell based on measurement as the basic resource and follows the first-report-first-process method, and selects the corresponding handover strategy (such as handover and redirection).

[0117] (4) Handover execution: The original base station applies for and allocates resources to the target base station, and then the source gNodeB makes a handover execution decision and sends the handover command to the UE. The UE performs the handover and data forwarding.

[0118] The handover process defined in 3GPP TS 38300 is shown in Figure 2.

[0119] 2. Artificial Intelligence (AI) and Communication Application Scenarios

[0120] AI and communications are among the 6G application scenarios outlined in ITU-R. Typical use cases include IMT-2030 (6G) assisted autonomous driving, autonomous collaboration between devices in medical assistance applications, cross-device / network computing offloading, creation and prediction of digital twins, and IMT-2030 (6G) assisted collaborative robots.

[0121] These application scenarios will require support for high mobile network capacity and high user experience data rates, as well as low latency and high reliability. Beyond communications, this application scenario is expected to include a suite of new functionalities integrating artificial intelligence and computing into 6G systems, including data acquisition, preparation, and processing from various sources; distributed AI model training; model sharing and distributed inference across mobile communication systems; and computing resource orchestration.

[0122] In related technologies, cloud services mainly define the static, long-term (e.g., monthly) service quality between cloud service providers and users through service level agreements (SLAs). Users are mainly enterprise users, with fewer direct consumer-facing users, especially mobile terminal consumers.

[0123] 3. Event configuration for traditional switching

[0124] The event configuration for traditional switching is shown in Table 4.

[0125] Table 4

[0126] Taking event A3 as an example, the meanings of the parameters in the entry and exit conditions are as follows:

[0127] Mn: Neighboring cell measurement results, without considering any offset.

[0128] Ofn: Specific offset of the neighboring measurement object

[0129] Ocn: Neighboring cell-level specific offset

[0130] Mp: Measurement results for Special Cells (SpCells) (such as the primary serving cell), without considering any offset.

[0131] Ofp: SpCell measures a specific offset of an object.

[0132] Ocp: SpCell cell-level specific offset

[0133] Hys: The hysteresis parameter of the event

[0134] Off: The offset parameter for the event.

[0135] To avoid ping-pong handover, the base station CondTriggerConfig configures a timeToTrigger parameter for each event. When the Layer 3 (L3) filtered signal quality of one or more candidate cells meets the event entry conditions within the timeToTrigger time, the UE will use the cell that meets the conditions as the trigger cell and select an execution condition reconfiguration in the trigger cell.

[0136] The following description, in conjunction with the accompanying drawings, details the access network device switching method, apparatus, and related equipment provided in this application through some embodiments and application scenarios.

[0137] Referring to Figure 3, which is a flowchart of an access network device handover method provided in an embodiment of this application, the access network device handover method includes the following steps:

[0138] Step 101: The first node receives first information, which includes at least one of measurement information and a computing service request;

[0139] Step 102: The first node determines whether to send first indication information to the first access network device based on the first information. The first indication information is used to determine whether to switch the service access network device of the terminal associated with the computing task.

[0140] In this embodiment, the first node can be a network-side device. For example, the first node can be a newly added network function node, an enhanced AMF, an enhanced SMF, or an enhanced base station, etc. It is understood that "enhancement" here can refer to adding or enhancing computing-related functions to the entity of the relevant 5G network-side device. It should be noted that this embodiment does not limit the name of the first node. For example, the first node can be called a computing management node, computing management function, computing control function, computing management and control function, computing service control function, or computing service management function, etc. The first node can be a radio access network node or a core network node. The first node is a network node responsible for receiving computing service requests or processing computing service requests, computing resource scheduling, computing information interaction, computing data processing, etc., at least one of these functions. The first node can be an enhanced AMF or an enhanced SMF, or it can be another enhanced network node or a newly defined network node.

[0141] In the embodiments of this application, a computing task can refer to one or a group of computing services initiated by a computing request node. Specifically, a computing task can be mapped to a Quality of Service (QoS) flow, or a computing task can be mapped to multiple QoS flows, or multiple computing tasks can be mapped to a single QoS flow. Alternatively, a computing task can be mapped to a radio bearer or physical layer resource.

[0142] The first indication information is used to determine whether to switch the service access network device of the terminal associated with the computing task. It can also be expressed as the first indication information being used to determine whether to switch the service access network device of the terminal associated with the computing service, wherein the computing task is associated with the computing service.

[0143] The first indication information can be used to indicate the performance requirements of the computing task. The first node can decide whether to send the first indication information to indicate the performance requirements of the computing task, so as to determine whether to switch the service access network device of the terminal based on whether the first access network device can meet the performance requirements of the computing task, thereby improving the computing service effect.

[0144] The first access network device can be the service access network device of the terminal associated with the computing task.

[0145] The performance requirements of a computing task can also be described as the performance required by the computing task, or the performance requirements of the computing task, etc.

[0146] In addition, computing tasks can also be described as AI tasks, and computing services can also be described as AI services.

[0147] It should be noted that the terminal associated with a computing task (or computing service) can refer to the terminal acting as either a sending node or a receiving node for the computing task (or computing service). For example, the terminal sends data for a computing task (or computing service), which is then transmitted over the network and processed, and the application function receives the data; or, the application function sends data for a computing task (or computing service), which is then transmitted over the network and processed, and the terminal receives the data; or, the terminal sends data for a computing task (or computing service), which is then transmitted over the network and processed, and another terminal receives the data; or, the terminal sends data for a computing task (or computing service), which is then transmitted over the network and processed, and the terminal receives the data.

[0148] The measurement information can be included in the measurement report.

[0149] In one embodiment, the first node sends a first indication message to the first access network device, the first indication message indicating the performance requirements of the computing task; the first node receives a second indication message sent by the first access network device, the second indication message indicating whether the performance requirements of the computing task are met; the first node determines whether to switch the service access network device of the terminal based on the second indication message.

[0150] In one implementation, the first node determines whether to send a first indication message to the first access network device based on the first information, including: the first node determines whether to switch the service access network device of the terminal associated with the computing task based on the first information; if it is determined to switch the service access network device of the terminal, the first node sends the first indication message to the first access network device; or, if it is determined not to switch the service access network device of the terminal, the first node does not send the first indication message to the first access network device.

[0151] In one implementation, taking the first node as a computing management node as an example, the computing management node sends first handover measurement configuration information to the terminal, and the computing management node receives the first measurement information sent by the terminal; or

[0152] The computing management node sends second handover measurement configuration information to the first access network device, and the computing management node receives the second measurement information sent by the first access network device; or

[0153] The computing management node sends third switching measurement configuration information to the source computing node, and the computing management node receives the third measurement information sent by the source computing node;

[0154] The computing management node determines whether to send the first instruction information to the first access network device based on at least one of the first measurement information, the second measurement information, and the third measurement information.

[0155] The first measurement information can be carried through the first measurement report, the second measurement information can be carried through the second measurement report, and the third measurement information can be carried through the third measurement report.

[0156] Alternatively, the computing management node receives a computing service request and determines whether to send the first instruction information to the first access network device.

[0157] The first access network device can be an access network device that transmits computing service data.

[0158] It should be noted that the first node can decide whether to send the first instruction information to the first access network device based on the measurement information. The first node may decide to send the first instruction information to the first access network device when the measurement information indicates that the current serving access network device cannot transmit the data of the computing task well; or, the first node may decide to send the first instruction information to the first access network device when the measurement information indicates that the data of the computing task transmitted through the current serving access network device cannot meet the performance requirements of the computing task; or, the first node may decide to send the first instruction information to the first access network device when the measurement information indicates that the data of the computing task transmitted through the current serving access network device cannot achieve the required computing service quality; etc., this embodiment does not limit this.

[0159] Furthermore, the first node can decide whether to send a first indication message to the first access network device based on the computing service request. The first node may decide to send the first indication message to the first access network device when the current serving access network device cannot adequately transmit the data of the computing task corresponding to the computing service request; or, the first node may decide to send the first indication message to the first access network device when the data of the computing task transmitted through the current serving access network device cannot satisfy the computing service request; or, the first node may decide to send the first indication message to the first access network device when the data of the computing task transmitted through the current serving access network device cannot achieve the computing service quality required by the computing service request; and so on. This embodiment does not limit this to any specific instance.

[0160] For example, if the computing task corresponding to the computing service request is not of the type that guarantees computing strength or is not of the time-sensitive type, then the first indication information is not sent. For example, if the computing task corresponding to the computing service request requires guaranteed computing strength, or is time-sensitive, or guarantees computing speed or is time-sensitive, or guarantees computing strength, or has a large minimum uplink bandwidth or minimum downlink bandwidth, then the first indication information is sent. Alternatively, if the computing node is the first access network device, and the computing node cannot support the computing service request, then the first node determines to switch the serving access network device and sends the first indication information.

[0161] In this embodiment of the application, in a mobile network communication system that supports computing services, a terminal can act as a sending node, receiving node, or computing node for computing services. The first information is used to determine whether to switch the service access network device of the terminal. Thus, when the first terminal acts as a sending node, receiving node, or computing node for computing services, it can support switching the access network device used to transmit computing service data. This embodiment of the application can solve the terminal switching problem in computing and communication services.

[0162] In related technologies, communication handover is used to ensure the continuity of communication services in order to address terminal mobility. AI and communication are among the application scenarios of 6G, but current mobile network protocols do not yet support the continuity of AI services or the continuity of AI and communication. Therefore, if 6G is to provide AI services or AI and communication services, a solution that ensures the continuity of these services is required.

[0163] In addition, the AI ​​and communication scenarios proposed by the International Telecommunication Union (ITU) may also include non-AI computing, so computing services can include both AI services and non-AI computing.

[0164] Potential computing service flows include on-demand compute offloading from mobile terminals and on-demand on-network compute from mobile terminals. On-demand compute offloading refers to the mobile terminal determining whether to offload computation to the network for processing based on local computing power, computation task requirements, power consumption, etc. If compute offloading is required, the data to be computed is sent to the network, and the computation result is obtained from the network. The performance of on-demand compute offloading is related to the performance of computing nodes, uplink transmission performance, downlink transmission performance, etc. On-demand on-network compute refers to providing computation services on demand for transmitted data during network transmission. Furthermore, based on the sending and receiving nodes that can transmit data, the scenarios can be divided as follows:

[0165] (1) The mobile terminal sends data, which is then transmitted and processed by the network, and the application functions receive the data.

[0166] (2) The application sends data, which is then transmitted over the network and processed by calculation before the mobile terminal receives the data.

[0167] (3) The mobile terminal sends data, which is then transmitted and processed by the network, and then another mobile terminal receives the data.

[0168] The performance of scenario (1) is related to the performance of computing nodes and uplink transmission performance; the performance of scenario (2) is related to the performance of computing nodes and downlink transmission performance; the performance of scenario (3) is related to the performance of computing nodes, the uplink transmission performance of the sending data terminal, and the downlink transmission performance of the receiving data terminal.

[0169] In computing and communication services, a switchover of the base station or computing node involved in computing and communication occurs due to one of the following reasons:

[0170] The movement of the UE or changes in channel quality lead to a decline in communication quality that cannot meet computing requirements, resulting in the switching of base stations involved in computing and communication service processes.

[0171] The addition of computing services to the UE leads to the switching of base stations involved in the computing and communication service processes;

[0172] Load balancing, computing node power consumption, and other factors related to computing management nodes / computing nodes necessitate improved communication performance to meet computing demands, leading to the switching of base stations involved in the computing and communication service processes.

[0173] Wherein, UE is the sending node and / or receiving node of the computing service, or the computing node. The base station is the serving base station of the UE.

[0174] In related technologies, there is currently no mature method for the handover process of base stations involved in computing and communication services.

[0175] In this embodiment, the computing service request can be used to determine base station handover caused by the terminal's computing service performance requirements. The measurement information corresponding to the first and second handover measurement configuration information can be used to determine base station handover caused by terminal movement or changes in channel quality; the measurement information corresponding to the third handover measurement configuration can be used to determine base station handover caused by computing nodes.

[0176] In this embodiment of the application, in a mobile network communication system that supports computing services, a terminal can act as a sending node, receiving node, or computing node for computing services. It determines whether to send first indication information to a first access network device based on the first information, thereby determining whether to switch the service access network device associated with the computing task. This allows for switching of the service access network device connected to the first terminal when the first terminal acts as a sending or receiving node for computing services; or, when the second terminal acts as a computing node, it allows for switching of the service access network device connected to the first terminal. This embodiment of the application can solve the terminal switching problem in computing and communication services.

[0177] In this embodiment, a first node receives first information, which includes at least one of measurement information and a computing service request. Based on the first information, the first node determines whether to send first indication information to a first access network device. This first indication information is used to determine whether to switch the serving access network device of the terminal associated with the computing task. Thus, by determining whether to send the first indication information to the first access network device using the first information, the first node can consider either the measurement information or the computing service request to decide whether to send the first indication information to determine whether to switch the serving access network device of the terminal associated with the computing task, thereby improving the computing service performance.

[0178] Optionally, the method further includes:

[0179] The first node sends a first indication message to the first access network device, the first indication message being used to indicate the performance requirements of the computing task;

[0180] The first node receives a second indication information sent by the first access network device, the second indication information being used to indicate whether the performance requirements of the computing task are met;

[0181] The first node determines whether to switch the service access network device of the terminal based on the second indication information.

[0182] Specifically, if the second indication information indicates that the first access network device cannot meet the performance requirements of the computing task, the first node may determine to switch the service access network device of the terminal; or, if the second indication information indicates that the first access network device can meet the performance requirements of the computing task, the first node may determine not to switch the service access network device of the terminal.

[0183] In this embodiment, the first node sends a first indication message to the first access network device; the first node receives a second indication message sent by the first access network device, the second indication message indicating whether the performance requirements of the computing task are met; the first node determines whether to switch the terminal's serving access network device based on the second indication message. In this way, the first node can determine to switch the terminal's serving access network device when the first access network device cannot meet the performance requirements of the computing task, thereby improving the computing service effect.

[0184] Optionally, the method further includes:

[0185] If it is determined to switch the service access network device, the first node sends a first switch request to the second access network device, the first switch request being used to request the second access network device to be switched to the service access network device of the terminal.

[0186] The decision to switch the service access network device can be made by the first node or the first access network device.

[0187] In one embodiment, the first access network device can meet the performance requirements of the computing task indicated by the first indication information, and the first access network device can schedule resources to meet the performance requirements of the computing task; or, if the first access network device cannot meet the performance requirements of the computing task indicated by the first indication information, the first access network device can send a second indication information to the first node, indicating that the performance requirements of the computing task cannot be met, and the first node determines to switch the service access network device.

[0188] In one implementation, if the first access network device cannot meet the performance requirements of the computing task indicated by the first indication information, the first access network device may determine to switch the serving access network device.

[0189] In this embodiment, a first switching request is sent from the first node to the second access network device. The second access network device can determine whether to agree to switch to the terminal's service access network device based on the first switching request, thereby realizing the switching of the terminal's service access network device and improving the computing service effect.

[0190] Optionally, after the first node sends a first handover request to the second access network device, the method further includes:

[0191] The first node receives a first handover response sent by the second access network device, the first handover response being used to indicate whether it agrees to hand over to the serving access network device of the terminal.

[0192] In this embodiment, the first node receives a first handover response sent by the second access network device. The first node can know whether the second access network device agrees to switch to the service access network device of the terminal through the first handover response, which facilitates the first node to make the next decision.

[0193] Optionally, the first handover request includes at least one of the following:

[0194] The minimum bit rate corresponding to the computing task; the maximum bit rate corresponding to the computing task; the maximum latency corresponding to the computing task.

[0195] The minimum bit rate corresponding to the computation task can represent the bit rate that the network guarantees to provide to the computation task within the average window.

[0196] The maximum bit rate corresponding to the computation task can represent the maximum bit rate that the network can provide for that computation task.

[0197] The maximum latency (or maximum air interface transmission latency) corresponding to the computing task can represent the maximum latency (uplink latency, downlink latency, or round-trip latency) that the network guarantees to provide to the computing task within the average window.

[0198] In this embodiment, through the information carried in the first handover request, the second access network device can determine whether it can meet the needs of the computing task based on the first handover request, and thus decide whether to agree to act as the service access network device for the terminal. This can better realize the handover of the service access network device and improve the computing service effect.

[0199] Optionally, the method further includes:

[0200] The first node sends a computing service response corresponding to the computing service request to the computing request node. The computing service response is used to indicate whether to accept or reject the computing service request. The computing request node is used to request computing services.

[0201] Where the first access network device or the second access network device can meet the performance requirements of the computing task, the first node may accept the computing service request; otherwise, it may reject the computing service request. When the computing service response is used to indicate acceptance of the computing service request, the computing service response may further include a computing task identifier or a computing node identifier.

[0202] In one implementation, the computing service response may further include PDU session information. For example:

[0203] If a new Protocol Data Unit (PDU) session needs to be established, the compute service response may also include an instruction to establish a PDU session.

[0204] If it is necessary to modify the PDU session, the compute service response may also include a modification PDU session indication or a PDU session ID.

[0205] If an existing PDU is reused, the compute service response may also include the PDU session ID, QoS flow ID, or QoS rule.

[0206] In one implementation, if the computing node is a radio access network node, the computing service response may further include a radio bearer indication, which may include a radio bearer ID. The radio bearer may be an SRB, DRB, or a new type of RB (e.g., a data plane RB). If it is necessary to create or modify an existing radio bearer, the first node may trigger the base station to send a radio bearer add or modify message.

[0207] In one implementation, if the computing node is a radio access network node, the computing service response may further include a physical layer channel indication or a physical layer resource indication. If computing data or computing response data is transmitted via a physical channel, the transmission latency of the corresponding computing data is expected to be further reduced.

[0208] In this embodiment, the first node sends a computing service response corresponding to the computing service request to the computing request node. The computing request node can know whether the first node accepts the computing service request, which facilitates the computing request node to make the next decision.

[0209] Optionally, before the first node receives the first information, the method further includes at least one of the following:

[0210] The first node sends first handover measurement configuration information to the terminal, wherein the measurement information includes first measurement information corresponding to the first handover measurement configuration information;

[0211] The first node sends second handover measurement configuration information to the first access network device, the measurement information including second measurement information corresponding to the second handover measurement configuration information;

[0212] The first node sends third handover measurement configuration information to the computing node, wherein the measurement information includes third measurement information corresponding to the third handover measurement configuration information, and the computing node is used to execute the computing task.

[0213] The first access network device can be the current serving access network device of the terminal associated with the computing task. The serving access network device of the terminal can be an access network device that serves the terminal, through which the terminal accesses the network.

[0214] The first measurement information may include: the uplink bandwidth or uplink bit rate corresponding to the computing task, the downlink bandwidth or downlink bit rate corresponding to the computing task, the location of the terminal, the remaining duration of the computing task, the end-to-end latency of the computing task, the computing failure rate of the computing task, the computing speed of the computing task, or the computing intensity of the computing task, etc. The first measurement information can be obtained by the terminal through measurement and can be carried in a first measurement report. This first measurement report can be an event-triggered report or a periodic report. For example, the first measurement report can be triggered by an event-triggered report.

[0215] The second measurement information may include: the uplink bandwidth or uplink bit rate corresponding to the computing task, the downlink bandwidth or downlink bit rate corresponding to the computing task, or the uplink channel quality of the terminal, etc. The second measurement information can be obtained by the first access network device and can be carried in a second measurement report. This second measurement report can be an event-triggered report or a periodic report. For example, the second measurement report can be triggered by an event.

[0216] The third measurement information may include: the computation latency of the computing task, the computation intensity of the computing task, the computation power consumption of the computing task, or the computational resource utilization rate of the computing task, etc. The third measurement information can be obtained by the computing node and can be carried in a third measurement report. This third measurement report can be an event-triggered report or a periodic report. For example, the third measurement report can be triggered by an event.

[0217] In this embodiment, at least one of the first measurement information corresponding to the first switching measurement configuration information, the second measurement information corresponding to the second switching measurement configuration information, and the third measurement information corresponding to the third switching measurement configuration information is used to determine whether to send a first indication information to the first access network device. The first indication information is used to determine whether to switch the service access network device of the terminal associated with the computing task, or the first indication information is used to indicate the performance requirements of the computing task. In this way, it is possible to determine whether to switch the service access network device of the terminal based on whether the first access network device can meet the performance requirements of the computing task, thereby improving the computing service effect.

[0218] Optionally, the first switching measurement configuration information includes at least one of the following: a first measurement object; a first measurement report configuration; a first measurement report triggering event; and related parameters of the first measurement report triggering event.

[0219] or

[0220] The second switching measurement configuration information includes at least one of the following: a second measurement object; a second measurement report configuration; a second measurement report trigger event; and related parameters of the second measurement report trigger event.

[0221] or

[0222] The third switching measurement configuration information includes at least one of the following: third measurement object; third measurement report configuration; third measurement report trigger event; and related parameters of the third measurement report trigger event.

[0223] The first measurement object can be represented by a computation task identifier, which identifies one or more computation tasks transmitted through the source cell that the UE needs to measure. If the computation task corresponds to a QoS flow, the first measurement object can also be represented by a QoS flow identifier (ID). If the computation task corresponds to a radio bearer, the first measurement object can also be represented by a radio bearer ID.

[0224] The second measurement object is represented by a computation task identifier, which identifies one or more computation tasks transmitted in one or more cells of the base station that need to be measured by the first access network device (e.g., a base station). If the computation task corresponds to a QoS flow, the second measurement object can also be represented by a QoS flow ID. If the computation task corresponds to a radio bearer, the second measurement object can also be represented by a radio bearer ID.

[0225] The third measurement object can be represented by a computation task identifier, which identifies one or more computation tasks processed by the computation node that need to be measured. If the computation task corresponds to a QoS flow, the third measurement object can also be represented by a QoS flow ID. If the computation task corresponds to a radio bearer, the third measurement object can also be represented by a radio bearer ID.

[0226] The first measurement report configuration includes the report type (or the reporting principle), which can be periodic reporting or event-triggered reporting; or the measurement report format, such as the maximum number of computational tasks to be reported.

[0227] The second measurement report configuration includes the report type, which can be periodic reporting or event-triggered reporting; or the measurement report format, such as the maximum number of computational tasks to be reported.

[0228] The third measurement report configuration includes the report type, which can be periodic reporting or event-triggered reporting; or the measurement report format, such as the maximum number of computational tasks to be reported.

[0229] In one implementation, the measurement report configuration (e.g., a first measurement report configuration, a second measurement report configuration, or a third measurement report configuration) may include a report type (reportType), which includes event-triggered reporting or periodic reporting. When the report type includes event-triggered reporting, the measurement configuration information is switched to include a measurement report triggering event (e.g., a first measurement report triggering event, a second measurement report triggering event, or a third measurement report triggering event).

[0230] In this embodiment, through the aforementioned first handover measurement configuration information, the terminal can perform measurements based on the first handover measurement configuration information to obtain first measurement information, which can be used to determine whether to send first indication information to the first access network device; or, through the aforementioned second handover measurement configuration information, the first access network device can perform measurements based on the second handover measurement configuration information to obtain second measurement information, which can be used to determine whether to send first indication information to the first access network device; or, through the aforementioned third handover measurement configuration information, the computing node can perform measurements based on the third handover measurement configuration information to obtain third measurement information, which can be used to determine whether to send first indication information to the first access network device.

[0231] Optionally, the first measurement report triggering event includes at least one of the following:

[0232] The uplink bandwidth or uplink bit rate corresponding to the computing task meets the preset conditions.

[0233] The downlink bandwidth or downlink bit rate corresponding to the computing task meets the preset conditions.

[0234] The location of the terminal meets the preset conditions;

[0235] The remaining time of the computing task meets the preset conditions;

[0236] The end-to-end computation latency of the computation task meets the preset conditions;

[0237] The failure rate of the computation task meets the preset conditions;

[0238] The computation speed of the computation task meets the preset conditions;

[0239] The computational intensity of the computational task meets the preset conditions.

[0240] For example, the uplink bandwidth or uplink bit rate corresponding to the computing task meeting the preset conditions may mean that the uplink bandwidth of the computing task (such as the first computing task) of the source cell measured by the terminal is always at or below a preset threshold within a preset time period, or the number of times it is below the preset threshold within the preset time period reaches a preset number.

[0241] For example, the downlink bandwidth or downlink bit rate corresponding to the computing task meeting the preset conditions may mean that the downlink bandwidth of the computing task (such as the first computing task) of the source cell measured by the terminal is always at or below a preset threshold within a preset time period, or the number of times it is below the preset threshold within the preset time period reaches a preset number.

[0242] For example, the location of the terminal meeting the preset conditions can mean that the location of the terminal is always outside the preset area within a preset time period.

[0243] In addition, for the three scenarios of terminal data transmission mentioned above (computation offloading, terminal data transmission during on-network computing, and terminal / AF data reception), optionally, the first measurement report triggering event may also include the remaining duration of the computing task (or computing service) meeting a preset condition. For example, the remaining duration of the computing task (or computing service) is not less than a preset threshold.

[0244] Additionally, for the terminal performing the calculation unloading, the first measurement report triggering event may optionally include at least one of the following:

[0245] (1) The end-to-end computation latency of the computation task meets preset conditions. End-to-end computation latency is used to define the total latency of the computation task during computation and transmission. Specifically, for example, the end-to-end computation latency for AI model inference includes at least one of the following:

[0246] Total end-to-end inference latency: Specifically, it refers to the total end-to-end latency of multiple consecutive inference operations. The calculation method is as follows: the time before the requesting node sends the first byte of the first computation task (or computation job) is denoted as T. IS The last byte received by the receiving node from all computing tasks (or computing jobs) is denoted as T. IE Then the computational latency budget for AI model inference is T. IE -T IS .

[0247] End-to-end inference latency: Specifically, it refers to the difference between the time it takes to send a sample and the time it takes to receive a result. That is, the time elapsed before the requesting node sends the first byte of a computation task (or job) is denoted as t. TIS The last byte received by the receiving node for the computation task (or job) is denoted as t. TIE Then the computational latency budget for AI model inference is t. TIE -t TIS .

[0248] (2) The computation failure rate (or expressed as failure rate) of the computation task meets the preset conditions. The failure rate refers to the number of failed requests for the computation task per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time. Failed requests include incomplete computation requests and computation requests that have exceeded the latency threshold. Valid requests refer to computation requests accepted and processed by the first node. Since computation task failures may include failures caused by transmission, statistical failure rate can better represent the actual failures of computation tasks.

[0249] (3) The computation speed of the computation task meets the preset conditions. Computation speed refers to the computation time complexity divided by the aforementioned end-to-end computation latency. For example, computation time complexity is usually represented by operations, and computation usually corresponds to a data type. 2 TFLOPs (floating-point operations) means that the time complexity of the computation is 2 × 10^12 floating-point operations. If the end-to-end computation latency is 20ms, then the computation speed is 2 × 10^12 / (20 × 10^(-3)) = 100 TFLOPS, where TFLOPS refers to the number of floating-point operations per second.

[0250] (4) The computational intensity of the computational task meets the preset conditions. Computational intensity refers to the computational speed divided by the bandwidth. The computational speed is as described above, and the bandwidth is the minimum value of the uplink bandwidth and the downlink bandwidth.

[0251] Additionally, when the computing management node is a radio access network node, especially in the case of an integrated 6G node B, the first measurement report triggering event may optionally include at least one of the conventional handover measurement events and parameters.

[0252] In this embodiment, the terminal can send the first measurement information obtained by measurement to the first node when the first measurement report triggering event is triggered, so that the first node can determine whether to send the first instruction information to the first access network device based on the first measurement information, and determine whether to switch the terminal's service access network device through the first instruction information, thereby improving the computing service effect.

[0253] Optionally, the second measurement report triggering event includes at least one of the following:

[0254] The uplink bandwidth or uplink bit rate corresponding to the computing task meets the preset conditions.

[0255] The downlink bandwidth or downlink bit rate corresponding to the computing task meets the preset conditions.

[0256] The uplink channel quality of the terminal meets the preset conditions.

[0257] For example, the uplink bandwidth or uplink bit rate corresponding to the computing task meets the preset conditions, which may mean that the uplink bandwidth of the source cell's computing task (such as the first computing task) measured by the first access network device (such as a base station) is always at or below a preset threshold within a preset time period, or the number of times it is below the preset threshold within a preset time period reaches a preset number.

[0258] For example, the downlink bandwidth or downlink bit rate corresponding to the computing task meets the preset conditions, which may mean that the downlink bandwidth of the source cell's computing task (such as the first computing task) measured by the first access network device (such as a base station) is always at or below a preset threshold within a preset time period, or the number of times it is below the preset threshold within a preset time period reaches a preset number.

[0259] It should be noted that the uplink bandwidth (or uplink bit rate) or downlink bandwidth (or downlink bit rate) can be measured by either the base station or the terminal.

[0260] For example, the uplink channel quality (e.g., RSRP, SINR, etc.) of the terminal meeting the preset conditions can mean that the uplink channel quality of the terminal corresponding to the computation task (e.g., the first computation task) of the source cell, as measured by the first access network device (e.g., a base station), remains at or below a preset threshold within a preset time period, or the number of times it falls below the preset threshold within the preset time period reaches a preset number. There can be one or more terminals corresponding to the computation task, and these terminals may differ for different computation tasks.

[0261] In this embodiment, the first access network device can send the second measurement information obtained by measurement to the first node when the second measurement report triggering event is triggered, so that the first node can determine whether to send the first instruction information to the first access network device based on the second measurement information, and determine whether to switch the terminal's service access network device through the first instruction information, thereby improving the computing service effect.

[0262] Optionally, the third measurement report triggering event includes at least one of the following:

[0263] The computation time delay of the computation task meets the preset conditions;

[0264] The computational power consumption of the computational task meets the preset conditions;

[0265] The computing resource utilization rate of the computing task meets the preset conditions;

[0266] The computational intensity of the computational task meets the preset conditions.

[0267] Among these, the computation latency of a computation task must meet preset conditions. Computation latency is used to define the total latency of the computation task during computation. For example, meeting the preset conditions for computation latency could mean that the computation latency of the computation task (such as the first computation task) measured by the computing node is consistently at or above a preset threshold within a preset time period, or that the latency exceeds the preset threshold a preset number of times within the preset time period. Specifically, for example, computation latency for AI model inference includes at least one of the following situations:

[0268] Total inference latency: Specifically, it refers to the total latency of multiple consecutive inference operations. The calculation method is as follows: the time before inference for the first computational task (or computational job) is denoted as T. ITS The time when all computational tasks (or computational jobs) finish inference is denoted as T. ITE Then the computational latency budget for AI model inference is T. ITE -T ITS .

[0269] Inference latency: Specifically, it refers to the difference between the start time and the end time of inference for a given sample. That is, the time taken before inference for a computational task (or job) is denoted as t. INS The time when the inference of this computational task ends is denoted as t. INE Then the computational latency budget for AI model inference is t. INE -t INS .

[0270] For the computational task to meet preset conditions, one method for calculating the computational power consumption is to calculate the power consumption of the computation node within the aforementioned computational delay time. Another method is: let P1 be the power consumption of the computation node per unit time when it is powered on, and P2 be the power consumption per unit time when processing the computational task. Then the computational power consumption is P2-P1 or the ratio of P2 to P1.

[0271] It should be noted that if the computing power consumption is too high, computing resources can be reduced, which can then be compensated for by shortening the communication transmission latency.

[0272] It should be noted that the high power consumption of computing limits the frequency of computing nodes, thus creating an upper limit to computing speed. Therefore, if the computing demand exceeds this speed limit, higher requirements are needed for communication transmission. For example, reducing transmission latency can provide more latency budget for computing processing, which may require switching access network equipment.

[0273] For example, the computing resource utilization rate of a computing task meets the preset conditions, which may mean that the utilization rate of the central processing unit (CPU) / graphics processing unit (GPU), or the memory utilization rate or storage utilization rate is always at or above a preset threshold within a preset time period, or the number of times the preset threshold is exceeded within a preset time period reaches a preset number.

[0274] It should be noted that when the computing resource utilization of a computing node exceeds a threshold, the actual computing speed may decrease due to factors such as resource contention between different tasks. In this case, higher requirements are needed for communication transmission, and it may be necessary to switch access network devices.

[0275] Among these, the computational intensity of the computational task must meet the preset conditions. Computational intensity refers to the computational speed divided by the bandwidth. As mentioned earlier, the computational speed is defined in two ways: one is memory bandwidth, and the other is the minimum value among memory bandwidth, uplink bandwidth, and downlink bandwidth.

[0276] Optionally, when the computing node is a terminal, the third measurement report triggering event may also include uplink bandwidth meeting preset conditions, or downlink bandwidth meeting preset conditions, or the UE's location meeting preset conditions.

[0277] In this embodiment, the computing node can send the third measurement information obtained from the measurement to the first node when the third measurement report triggering event is triggered, so that the first node can determine whether to send the first indication information to the first access network device based on the third measurement information, and determine whether to switch the terminal's service access network device through the first indication information, thereby improving the computing service effect.

[0278] Optionally, the first indication information includes at least one of the following:

[0279] Switch identifier;

[0280] The minimum bit rate corresponding to the computation task;

[0281] The maximum bit rate corresponding to the computing task;

[0282] The maximum latency corresponding to the computing task;

[0283] Identification of candidate access network devices.

[0284] For the switching identifier, for example, one bit is used to indicate whether a switch has been made. For instance, one bit indicates a switch if it is 1 and no switch if it is 0.

[0285] The minimum bit rate corresponding to the computation task can represent the bit rate or minimum bit rate increment that the network guarantees to provide to the computation task within the average window. The minimum bit rate increment is used to represent the increase in the bit rate that the network guarantees to provide to the computation task within the average window.

[0286] The maximum bit rate corresponding to the computing task can represent the maximum bit rate or the maximum bit rate increment that the network can provide for the computing task. The maximum bit rate increment is used to represent the increase in the maximum bit rate that the network can provide for the computing task.

[0287] The maximum latency corresponding to the computing task represents the maximum latency or maximum latency reduction that the network guarantees to provide to the computing task within the average window. The maximum latency reduction represents the reduction in the maximum latency that the network guarantees to provide to the computing task within the average window.

[0288] The identifier of the candidate access network device can be set in the candidate access network device list. The candidate access network device (such as the candidate target base station) is the candidate access network device that the terminal switches to when the first access network device cannot meet the computing performance requirements.

[0289] In this embodiment, by switching the identifier or the identifier of the candidate access network device, the first access network device can learn through the first indication information that it needs to switch the serving access network device of the terminal associated with the computing task; or, by using the minimum bit rate, the maximum bit rate, or the maximum latency corresponding to the computing task, the first access network device can learn through the first indication information that the computing task has performance requirements, and thus determine whether it can meet the performance requirements of the computing task, so as to determine whether to switch the serving access network device of the terminal associated with the computing task.

[0290] Optionally, the computing service request includes at least one of the following:

[0291] The following parameters are specified: computing service identifier; resource type of computing resources required by the computing task; minimum number of operations required by the computing task; minimum computing speed required by the computing task; minimum computing intensity required by the computing task; computing latency budget required by the computing task; maximum failure rate of the computing task; average window of the computing task statistics; maximum duration of the computing task; computing power type of the computing task; data type of the computing task; minimum memory required by the computing task; minimum storage space required by the computing task; minimum transmission bandwidth required by the computing task; arrival mode of the computing task; parameters of the arrival mode of the computing task; training accuracy of the AI ​​model corresponding to the computing task; AI performance parameters of the AI ​​model corresponding to the computing task; minimum inference throughput of the AI ​​model corresponding to the computing task; computing power consumption threshold of the computing task; computing energy efficiency threshold of the computing task.

[0292] The computing service identifier is used to identify computing services. Examples include one-dimensional Discrete Fourier Transform (DFT), two-dimensional Fast Fourier Transform (FFT), AI model training, and AI model inference. AI model training or inference can further include image recognition, object detection, semantic segmentation, recommendation, natural language processing, speech recognition, optical character recognition, face recognition, beam management, localization, perception, and Channel State Information (CSI) feedback.

[0293] The resource types of computing resources required for a computing task can also be referred to as computing resource types, or computing and communication resource types. Potential resource types include guaranteed computing rate (GCR or guaranteed operational rate, GOR), guaranteed computing intensity (GCI or guaranteed operational intensity, GOI), non-guaranteed computing rate (Non-GCR or Non-GOR), non-guaranteed computing intensity (Non-GCI or Non-GOI), delay-critical guaranteed computing rate (delay-critical GCR or delay-critical GOR), and delay-critical guaranteed computing intensity (delay-critical GCI or delay-critical GOI).

[0294] The minimum number of operations (or operands) for a computation task is defined as the minimum number of operations or operands required for that computation task.

[0295] The minimum computational speed required for a computational task is defined as the computational time complexity divided by the tolerable upper limit of computation time. For example, computational time complexity is typically represented by operations, and computations often correspond to a data type (see data type description below). 2 TFLOPs (floating-point operations) indicates that the computational time complexity is 2 × 10^12 floating-point operations. If the tolerable upper limit of computation time is 20ms, meaning the computation can be completed in a maximum of 20ms, then the computational speed is 2 × 10^12 / (20 × 10^(-3)) = 100 TFLOPS.

[0296] Optionally, the minimum computing speed includes the theoretical minimum computing speed and / or the actual minimum computing speed. The actual minimum computing speed can be represented by test case indicators and the actual minimum computing speed itself. Alternatively, it can be represented by the theoretical minimum computing speed, test case indicators, and computational efficiency. Or, it can be represented by the actual minimum computing speed, test case indicators, and computational efficiency itself.

[0297] In this context, the minimum computational intensity required for a computational task is defined as computational speed divided by bandwidth. As mentioned earlier, in the process of providing computational services in 6G, bandwidth consists of multiple components, including the transmission bandwidth between the requesting node (e.g., UE) and the computational node, and the memory bandwidth of the computational node. One method of defining computational intensity is segmented, such as computational speed divided by memory bandwidth. Another method is to take the minimum of the aforementioned related bandwidths as the numerator, i.e., computational speed divided by min{memory bandwidth, transmission bandwidth between UE and computational node}. The transmission bandwidth between the UE and computational node can be further divided into the air interface bandwidth between the UE and the access network node, and the wired transmission bandwidth between the access network node and the computational node. Alternatively, the transmission bandwidth between the UE and computational node can be further divided into the bandwidth between the UE and the User Plane Function Node (UPF) node, and the wired transmission bandwidth between the UPF and the computational node.

[0298] The computing delay budget (CDB) required for the computing task can be defined as the upper limit of the latency (i.e., the maximum latency) that the computing task can tolerate when computing between the computing request node (such as the UE) and the computing node.

[0299] The upper limit of tolerable latency during computation refers to the computation latency of the computing node.

[0300] The upper limit of tolerable latency during transmission refers to the sum of the transmission latency from the requesting node to the computing node and the transmission latency from the computing node to the receiving node.

[0301] One definition is the length of the time interval between the first data packet of a single computational task being sent and the last data packet of the received computational task. Another definition is the length of the time interval between the first data packet of a group of computational tasks being sent and the last data packet being received. For example, for image recognition computational tasks, one approach is to treat single image recognition as a single computational task, while another approach is to treat multiple images (e.g., 100 images) as a group of computational tasks.

[0302] Specifically, computational latency budgets for AI model inference include at least one of the following:

[0303] Total end-to-end inference latency: Specifically, it refers to the total end-to-end latency of multiple consecutive inference operations. The calculation method is as follows: the time before the requesting node sends the first byte of the first computation task (or computation job) is denoted as T. IS The last byte received by the receiving node from all computing tasks (or computing jobs) is denoted as T. IE Then the computational latency budget for AI model inference is T. IE -T IS .

[0304] Total inference latency: Specifically, it refers to the total latency of multiple consecutive inference operations. The calculation method is as follows: the time before inference for the first computational task (or computational job) is denoted as T. ITS The time when all computational tasks (or computational jobs) finish inference is denoted as T. ITE Then the computational latency budget for AI model inference is T. ITE -T ITS .

[0305] End-to-end inference latency: Specifically, it refers to the difference between the time it takes to send a sample and the time it takes to receive a result. That is, the time elapsed before the requesting node sends the first byte of a computation task (or job) is denoted as t. TIS The last byte received by the receiving node for the computation task (or job) is denoted as t. TIE Then the computational latency budget for AI model inference is t. TIE -t TIS .

[0306] Inference latency: Specifically, it refers to the difference between the start time and the end time of inference for a given sample. That is, the time taken before inference for a computational task (or job) is denoted as t. INS The time when the inference of this computational task ends is denoted as t. INE Then the computational latency budget for AI model inference is t. INE -t INS .

[0307] The maximum failure rate for a computation task is calculated by dividing the number of failed requests per unit time (e.g., per second, per 5 minutes, per day) by the total number of valid requests per unit time. Failed requests include incomplete computation requests and computation requests that have exceeded the latency threshold. Valid requests refer to computation requests accepted and processed by the first node.

[0308] Among them, the average window for the statistics of computing tasks can be the average statistical time window of computing speed, computing intensity, or computing delay budget.

[0309] The maximum duration of the computation task can be represented by one or more of the start time, duration, and end time.

[0310] The computing power type of the computing task can be at least one of the following: Central Processing Unit (CPU), Graphics Processing Unit (GPU), Field Programmable Gate Array (FPGA), Data Processing Unit (DPU), Smart Network Interface Card (SmartNIC), Tensor Processing Unit (TPU), and Neural Network Processing Unit (NPU) (e.g., a combination of two or more). Optionally, the computing power type may also include at least one of the following:

[0311] Clock speed;

[0312] Number of cores.

[0313] The data type of the computation task can be at least one of integers (such as int8, int4, etc.) and floating-point numbers (such as half-precision floating-point numbers, single-precision floating-point numbers, double-precision floating-point numbers, half-precision floating-point numbers, etc.).

[0314] The minimum memory required for the computing task can be the lower limit of the memory required for the computing task, and can be represented by at least one of the following: memory size (e.g., 8G), sustainable memory bandwidth, and memory random access rate.

[0315] The minimum storage space required for the computing task can refer to minimum storage, which defines the lower limit of storage required for the computing task. This minimum storage can be represented by at least one of storage size (e.g., 1T) and storage bandwidth (the maximum input / output (IO) flow per unit time).

[0316] The minimum transmission bandwidth required for the computation task can be used to define the tolerable lower limit of uplink bandwidth and / or downlink bandwidth for the computation task. It can be expressed by at least one of the following:

[0317] Uplink or downlink bandwidth indicator, for example, 0 represents uplink bandwidth and 1 represents downlink bandwidth;

[0318] The uplink and downlink bandwidth are the same, for example, 0 means that the uplink bandwidth and downlink bandwidth are different, and 1 means that the uplink bandwidth and downlink bandwidth are the same;

[0319] Minimum uplink bandwidth;

[0320] Minimum downlink bandwidth.

[0321] This includes the computation task arrival mode (or computation job arrival mode) and parameters. A computation task may contain multiple computation jobs, and the potential modes and parameters include at least one of the following:

[0322] Consecutive arrival mode or single arrival mode: The i-th job (where i is a positive integer) arrives immediately after the (i-1)-th job is completed. Job i is not sent if job (i-1) is not completed or the delay budget threshold is not met.

[0323] Fixed-period arrival mode: Jobs arrive at a fixed period T, with n jobs arriving at a time (n is a positive integer);

[0324] Poisson distribution arrival pattern: Operations based on Where k is the number of jobs arriving per unit time (k is a positive integer), and λ (λ is a positive integer) is the average number of jobs arriving per unit time (e.g., per second);

[0325] Peak arrival pattern: In the Poisson distribution arrival pattern, there are j short periods, each period has a sudden surge in a large number of jobs, and the period lasts for a certain duration T. G (e.g., 5s-10s), and maintain a certain concurrency level σ (σ is a positive integer, e.g., σ>2). 5 (Number of jobs / second), jobs arriving within a short period conform to the fixed-period arrival pattern;

[0326] Offline arrival mode: All items arrive at once;

[0327] Mixed arrival mode: Composed of more than one of the above arrival modes.

[0328] The training precision of the AI ​​model corresponding to the computation task can be a training precision, which can be represented by the data type of the AI ​​model parameters output, such as single-precision floating-point numbers or half-precision floating-point numbers.

[0329] The AI ​​performance parameters of the AI ​​model corresponding to the computational task can include AI performance thresholds, which are the tolerable limits for AI model training and / or the lower limit of AI model inference performance. For AI models, performance parameters typically differ across different scenarios. For example, image recognition and object detection performance corresponds to top-1 accuracy and average accuracy, semantic segmentation performance corresponds to Mean Intersection Over Union (MIOU), and speech recognition performance corresponds to Word Error Rate (WER). For large models, the performance lower limit can be represented by the score of large model benchmark tests. Optionally, the AI ​​performance lower limit can also be represented by at least one of the following:

[0330] The test dataset indicator indicates which dataset, when used, yields performance at least equal to the stated AI performance lower limit. Commonly used AI datasets include ImageNet2012, Pascal VOC2012, LibriSpeech ASR Corpus, or Criteo, etc.

[0331] The minimum inference throughput of the AI ​​model corresponding to the computation task can refer to the minimum inference throughput rate of the AI ​​model. For vision-related tasks, this is usually the number of images inferred per second (images / s), while for natural science tasks, it is the number of sentences inferred per second (sentences / s) or tokens / s. Here, "tokens" refers to words, punctuation marks, or other text units in the input text processed by the model.

[0332] Among these, the power consumption threshold for the computing task is, for example, the maximum computing power consumption. One approach is to calculate the power consumption of the computing node within the aforementioned computing latency budget. Another approach is to denote the power consumption of the computing node per unit time when it is powered on as P1, and the power consumption per unit time when processing a computing task as P2. Then, the computing power consumption is P2 - P1 or the ratio of P2 to P1.

[0333] Among these, the energy efficiency threshold for computing tasks includes, for example, minimum energy efficiency. Minimum energy efficiency is the computing speed per unit time divided by the power consumption, or the AI ​​model inference throughput divided by the power consumption.

[0334] It should be noted that there are conversion relationships between some of the above parameters. Therefore, if it is necessary to indicate the amount of computation (e.g., number of operands, computation speed, computation intensity, etc.), at least one of the following parameter combinations can be included in the computation service request to represent the computation service information:

[0335] Combination 1: Minimum computation speed for the computation task. The first node can use the minimum computation speed as a parameter for the computation node.

[0336] Combination 2: Minimum number of operations or operands for the computation task and computation latency budget. If the computation latency budget only includes computation latency, then the first node can use these two parameters as computation node selection parameters. If the computation latency budget includes end-to-end latency, then the first node can use the allocation information for data transmission latency and computation latency, along with these two parameters, as computation node selection parameters.

[0337] Combination 3: The computing power type of the computation task (e.g., CPU, clock speed or number of cores), minimum memory, minimum storage space, and maximum duration of the computation task. The first node can use these parameters as the selection parameters for the computing node. These parameters are relatively static and easy to select.

[0338] Combination 4: Based on Combination 1, increase the minimum transmission bandwidth of the computation task.

[0339] Combination 5: Minimum computational intensity and computational delay budget for the computational task.

[0340] In this embodiment, the first node can determine the performance requirements of the computing task through the information carried in the computing service request. Based on the performance requirements of the computing task, it can decide whether to switch the service access network device of the terminal associated with the computing task, or send the performance requirements to the first access network device to decide whether to switch the service access network device of the terminal associated with the computing task, thereby improving the computing service effect.

[0341] The following examples provide further explanation of the access network device handover method:

[0342] In the example below, we will use the first node as the computing management node, the first access network device as the base station (such as the source base station), and the second access network device as the target base station for illustration.

[0343] Example 1:

[0344] This example demonstrates base station handover based on measurement information.

[0345] In this example, for a UE, base station, or computing node that is currently providing computing services, the system determines whether to switch the UE's serving base station based on measurement information, thereby solving the UE handover problem in computing and communication services.

[0346] The aforementioned base stations providing computing services refer to base stations transmitting data for computing services provided by the 6G network. The aforementioned computing nodes providing computing services refer to computing nodes providing computing services. The potential computing service flows for the aforementioned UEs providing computing services include on-demand computing offloading and on-demand on-network computing for the mobile terminal. On-demand computing offloading refers to the mobile terminal determining whether to offload computing to the network for processing based on local computing power, computing task requirements, power consumption, etc. If computing offloading is required, then the data to be computed is sent to the network, and the computation result is obtained. The performance of on-demand computing offloading is related to the performance of the computing node, uplink transmission performance, downlink transmission performance, etc. On-demand on-network computing refers to providing computing services on demand for the transmitted data during network transmission. Furthermore, based on the sending and receiving nodes that can transmit data, the following scenarios can be identified:

[0347] (1) The mobile terminal sends data, which is then transmitted and processed by the network, and the application functions receive the data.

[0348] (2) The application sends data, which is then transmitted over the network and processed by calculation before the mobile terminal receives the data.

[0349] (3) The mobile terminal sends data, which is then transmitted and processed by the network, and then another mobile terminal receives the data.

[0350] The performance of scenario (1) is related to the performance of computing nodes and uplink transmission performance; the performance of scenario (2) is related to the performance of computing nodes and downlink transmission performance; the performance of scenario (3) is related to the performance of computing nodes, the uplink transmission performance of the sending data terminal, and the downlink transmission performance of the receiving data terminal.

[0351] As shown in Figure 4, the access network device handover method includes the following process:

[0352] Step (11): The computing management node sends the first handover measurement configuration information to the UE. After receiving the handover measurement configuration, the UE performs handover measurement and sends the first handover measurement report back to the computing management node.

[0353] or

[0354] The computing management node sends the second handover measurement configuration information to the base station. After receiving the handover measurement configuration, the base station performs handover measurement and sends the second handover measurement report back to the computing management node; or the computing management node subscribes to the second handover measurement configuration information from the base station. If the preset conditions are met, the base station sends a subscription notification to the computing management node.

[0355] or

[0356] The computing management node sends the third handover measurement configuration information to the computing node (which may be a core network node, a radio access network node, or a UE). After receiving the handover measurement configuration, the base station performs handover measurement and sends the third handover measurement report back to the computing management node. Alternatively, the computing management node subscribes to the third handover measurement configuration information from the computing node. If the preset conditions are met, the computing node sends a subscription notification to the computing management node.

[0357] It should be noted that, depending on the specific computing task, the number of computing nodes can be one or more.

[0358] The first switching configuration information includes at least one of the following:

[0359] First measurement object; first measurement report configuration; first measurement event and related parameters.

[0360] The first measurement object is described in the preceding description of the first measurement object, and will not be repeated here.

[0361] The configuration of the first measurement report is described in the aforementioned description of the configuration of the second measurement report, and will not be repeated here.

[0362] The first measurement report triggering event is described in the preceding description of the first measurement report triggering event, and will not be repeated here.

[0363] The second switching configuration information includes at least one of the following:

[0364] Second measurement object; second measurement report configuration; second measurement event and related parameters.

[0365] The second measurement object is described above in the section on the second measurement object, and will not be repeated here.

[0366] The configuration of the second measurement report is described in the preceding section and will not be repeated here.

[0367] The second measurement report triggering event is described in the preceding description of the second measurement report triggering event, and will not be repeated here.

[0368] The third switching configuration information includes at least one of the following:

[0369] Third measurement object; third measurement report configuration; third measurement event and related parameters.

[0370] The third measurement object is described in the preceding section on the third measurement object, and will not be repeated here.

[0371] The configuration of the third measurement report is described in the preceding section on the configuration of the third measurement report, and will not be repeated here.

[0372] The third measurement report triggering event is described in the aforementioned description of the third measurement report triggering event, and will not be repeated here.

[0373] Step (12): Based on the measurement report from step (11), the computing management node decides whether to send a computing performance indication (first indication information) to the source base station. For example, if it does not affect the quality of the computing service, then it does not send a computing performance indication and maintains or terminates the current computing service. For example, if the remaining time of the computing service is long and it affects the quality of the computing service, then it sends a computing performance indication.

[0374] The computational performance indicator is used to indicate the performance required for a computational task, and includes at least one of the following:

[0375] (1) Switching indicator, for example, 1 bit is used to indicate whether to switch, 1 indicates switching, and 0 indicates not switching.

[0376] (2) Minimum bit rate, which represents the bit rate that the network guarantees to provide to the computation task within the average window. Or, minimum bit rate increment, which represents the increase in the bit rate that the network guarantees to provide to the computation task within the average window.

[0377] (3) Maximum bit rate, which represents the maximum bit rate that the network can provide for the computing task. Or maximum bit rate increment, which represents the increase in the maximum bit rate that the network can provide for the computing task.

[0378] (4) Maximum latency, which represents the maximum latency that the network guarantees to provide to the computing task within the average window. Or, maximum latency reduction, which represents the reduction in the maximum latency that the network guarantees to provide to the computing task within the average window.

[0379] Optionally, the computational performance indicator may also include a list of candidate target base stations. The list of candidate target base stations is used as a candidate target base station for UE handover when the source base station cannot meet the computational performance requirements.

[0380] Steps (13) and (14): The source base station determines whether to configure UE measurement and reporting based on the computing performance indication, the current base station resource status, load status, and UE measurement information. If UE measurement and reporting are required, the existing handover process can be reused, so it will not be described in detail here.

[0381] Alternatively, the source base station may determine whether to switch based on computing performance indicators, current base station resource status, load status, and UE measurement information.

[0382] Specifically, the following situations apply:

[0383] (1) If the source base station can meet the computing performance indication, then the scheduled resources meet the performance requirements of the UE's computing task; or, if the source base station cannot meet the computing performance indication, the source base station sends a computing performance response to the computing management node, indicating that the requirements of the computing performance indication cannot be met. The computing management node determines to initiate a handover request and sends a first handover request to at least one candidate target base station.

[0384] (2) If the source base station cannot meet the computing performance indication, then the source base station determines to initiate a handover request. The source base station sends a first handover request to at least one candidate target base station. The candidate target base station may be determined by the source base station, or the candidate target base station from step (13) above may be used.

[0385] The first handover request includes at least one of the following:

[0386] Minimum bit rate represents the bit rate that the network guarantees to provide to the computational task within the average window.

[0387] Maximum bit rate indicates the maximum bit rate that the network can provide for this computational task;

[0388] Maximum latency (or maximum air interface transmission latency) represents the maximum latency (uplink latency, downlink latency, or round-trip latency) that the network guarantees to provide to the computing task within an average window.

[0389] Step (15): The candidate target base station determines whether to accept the handover based on the first handover request. It sends the first handover response, which can be divided into the following two cases:

[0390] If agreed, the candidate target base station sends a first response message to the first handover request sender (source base station or computing management node). The first response message indicates to the first handover request sender that the first response message sender agrees to perform the handover. The existing handover procedure can be reused to perform the handover.

[0391] If disagreement is not made, the candidate target base station may optionally send a first rejection message to the first handover request sender (source base station or computing management node), wherein the first rejection message indicates to the first handover request sender that the first rejection message sender refuses the handover.

[0392] Subsequent procedures may include any of the following:

[0393] The source base station or computing management node re-determines the candidate target base station;

[0394] Maintain the serving base station for the current UE computing task;

[0395] End the current computation task.

[0396] Example 2:

[0397] This example implements base station handover based on computing service requests.

[0398] Example 1 uses measurement reports to determine whether to send a computing performance indicator or a handover indicator for ongoing computing services. In this example, the UE determines whether to send a computing performance indicator or a handover indicator when initiating a computing service request, thus solving the UE handover problem in computing and communication services.

[0399] Taking the UE as the computing request node as an example, as shown in Figure 5, the access network device handover method includes the following process:

[0400] Step (21): The computing request node sends a computing service request to the computing management node. The computing request node can be a UE, AF, or NF. If it is an AF, the computing service request needs to be sent to the computing management node through NEF, etc. The computing service request is described in the previous section on computing service requests, and will not be repeated here.

[0401] Step (22): Based on the computing service request in step (21), the computing management node decides whether to send a computing performance indication (first indication information) to the source base station. For example, if it is not a type that guarantees computing strength or a time-sensitive type, then the computing performance indication is not sent. For example, if it guarantees computing strength or time-sensitive computing speed or time-sensitive computing strength, or if the minimum uplink bandwidth or minimum downlink bandwidth is large, then the computing performance indication is sent. Alternatively, if the computing node is a radio access network node, and the computing node cannot support the requested computing service, then the computing management node determines the handover and sends the computing performance indication.

[0402] The computational performance indicator is used to indicate the performance required for a computational task, and includes at least one of the following:

[0403] A switching indicator, for example, uses one bit to indicate whether to switch, where 1 indicates switching and 0 indicates not switching;

[0404] Minimum bit rate represents the bit rate that the network guarantees to provide to the computational task within the average window.

[0405] Maximum bit rate indicates the maximum bit rate that the network can provide for this computational task;

[0406] Maximum latency represents the maximum latency that the network guarantees to provide to the computational task within the average window.

[0407] Optionally, the computational performance indicator may also include a list of candidate target base stations. The list of candidate target base stations is used as a candidate target base station for UE handover when the source base station cannot meet the computational performance requirements.
