[0120] Driven by the demand for low latency, large bandwidth, and immersive communications from emerging applications such as the Metaverse and holographic calls, the development of collaborative computing between terminals and base stations is becoming increasingly important. During the collaborative computing process between terminals and base stations, the terminal can offload all or part of the computing tasks to its own service base station for execution. The service base station completes the computing tasks offloaded by the terminal based on the configuration information related to the computing between the terminal and the base station.

[0121] In the related technology, the switching process does not involve the interaction of configuration information related to computing. Therefore, in the scenario where the terminal performs collaborative computing with the source base station, when the service base station of the terminal is switched from the source base station to the target base station, the target base station cannot obtain the configuration information related to the computing between the source base station and the terminal, resulting in the target base station being unable to continue to perform collaborative computing with the terminal, affecting the continuity of the computing process.

[0122] Based on this, in each embodiment of the present application, the first base station receives a first request sent by the second base station; wherein the first request is used to request that the service base station of the first terminal be switched from the second base station to the first base station, and the first request carries the first information, and the first information represents the computing configuration information used for the first terminal to perform collaborative computing with the base station. In this way, the second base station can obtain the first information through the first request. It can be understood that the first information is also the configuration information related to the computing between the second base station and the first terminal. On this basis, when the service base station of the first terminal is switched from the second base station to the first base station, the target base station can continue to perform collaborative computing with the first terminal, ensuring the continuity of the computing process.

[0123] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0124] For ease of understanding, the overall interaction process of this solution is first described, wherein the devices involved in the interaction include: the target base station for the terminal to switch, the source base station, and the terminal. Figure 1 ,The overall interaction process of this scheme includes the following steps:

[0125] Step 101: The terminal and the source base station perform collaborative calculations.

[0126] In practical applications, the collaborative computing between the terminal and the base station can be understood as: the terminal and the base station jointly achieve a computing goal. For example, the computing goal can be channel state information (CSI) decompression based on artificial intelligence (AI), extended reality (XR) rendering, etc. A computing goal can also be understood as an overall task.

[0127] In practical applications, a computing target can also be understood as an overall task or a computing task. An overall task can be split into one or more computing tasks, and the base station and the terminal can cooperate to perform them, so as to achieve the computing target. The one or more computing tasks can be regarded as one or more computing tasks related to the computing target, or one or more computing tasks related to the overall task. The terminal and the base station cooperate to perform one or more computing tasks related to the overall task, which can be regarded as: the terminal and the base station cooperate to perform the overall task.

[0128] In actual applications, the terminal can offload some of the computing tasks related to the computing target to the base station for execution. In the process of executing the computing tasks offloaded by the terminal, the base station may require the terminal to collect relevant data and report it to the base station. The base station can also execute all computing tasks related to the computing target. In the process of executing all computing tasks, the base station requires the terminal to collect relevant data and report it to the base station. In this case, it can also be regarded as the terminal offloading all computing tasks related to the computing target to the base station for execution.

[0129] In actual applications, the terminal and the base station perform collaborative computing based on the computing-related configuration information. The computing-related configuration information can also be expressed as computing information.

[0130] The calculation information may include: one or more of the following calculation configuration information related to the calculation task performed by the terminal in the collaborative calculation with the base station:

[0131] Task ID: used to identify the computing task performed when the terminal and the base station perform collaborative computing.

[0132] In practical applications, the task identifier may be allocated by a base station that performs computation in collaboration with the terminal.

[0133] It is understandable that in order to jointly achieve a computing goal, the terminal and the base station may need to collaborate to perform multiple computing tasks. Therefore, the computing information may include multiple task identifiers, each task identifier corresponds to a computing task, and each task identifier is associated with the computing configuration information related to the corresponding computing task.

[0134] Computing function: used to describe the function of a computing task. For example, the function of a computing task may be: CSI feedback enhancement.

[0135] In practical applications, the calculation function can be used by the base station to search for or load a calculation file and / or a calculation model that matches the calculation function.

[0136] QoS parameters: used to describe the service quality of a computing task. For example, QoS parameters may include: computing time, computing accuracy, etc.

[0137] Data collection configuration: used to describe the way the terminal collects data during collaborative computing.

[0138] In practical applications, the data collection configuration may include data type and / or data collection frequency. The data type is used to indicate the type of data that the terminal needs to collect. For example, the data type may be reference signal received power (RSRP), uplink and downlink rates, CSI, or computing power information of the terminal. The data collection frequency is used to indicate the frequency of data collection by the terminal. For example, the data collection frequency may be: periodic collection or event reporting, etc. In the case where the data collection frequency is periodic collection, the data collection configuration may also include: collection period.

[0139] In practical applications, the terminal may need to collect relevant data and report it to the base station to support the base station in performing computing tasks. It is understandable that in the process of performing a computing task, the base station may need the terminal to collect multiple types of data. Therefore, the data collection configuration can be a list, and each list item in the list corresponds to a type of data that needs to be collected.

[0140] Computing resource configuration on the terminal side: used to describe how computing resources are configured on the terminal during collaborative computing.

[0141] In actual applications, the computing resource configuration on the terminal side may include:

[0142] Configuration of computing models supported by the terminal, and / or configuration of computing models used by the terminal during collaborative computing.

[0143] In actual applications, the terminal may support multiple computing models, so the configuration of the computing models supported by the terminal may be a list, each list item of which is used to describe a computing model supported by the terminal. The list may also be expressed as a computing model list supported by the terminal.

[0144] In actual applications, when the base station unilaterally performs computing tasks, the configuration of the computing model used in the terminal collaborative computing can be empty.

[0145] Computing resource configuration on the base station side: used to describe how computing resources are configured on the base station during collaborative computing.

[0146] In actual applications, the computing resource configuration on the base station side may include: configuration information of the computing model used by the base station during collaborative computing.

[0147] In practical applications, the computing configuration information in the computing information can form a list, each list item in the list corresponds to a computing task related to the computing target, and each list item can include one or more computing configuration information related to the corresponding computing task. The list can also be expressed as a computing information list.

[0148] It can be understood that the computing tasks performed by the terminal and the base station during collaborative computing are computing tasks related to the computing target. Therefore, the computing target is understood as the overall task, and one or more computing configuration information in the computing information can also be regarded as related to the overall task. In practical applications, the computing tasks performed by the terminal and the base station during collaborative computing can also be regarded as computing tasks related to the computing information.

[0149] In actual applications, the base station that performs cooperative computing with the terminal can obtain computing information between the terminal and the source base station. Here, before the serving base station of the terminal is switched from the source base station to the target base station, the terminal and the source base station perform cooperative computing, so the source base station can obtain computing information between the terminal and the source base station.

[0150] Step 102: The source base station sends a radio resource management (RRM) measurement configuration to the terminal.

[0151] Step 103: The terminal reports the RRM measurement result to the source base station.

[0152] Specifically, the terminal measures the surrounding environment based on the RRM measurement configuration sent by the source base station, and reports the measurement result to the source base station so that the source base station can make a handover decision.

[0153] Step 104: The source base station makes a handover decision.

[0154] Specifically, the source base station determines whether the terminal performs handover according to the measurement result reported by the terminal, and initiates a handover request to one or more candidate target base stations if it is determined that the terminal performs handover.

[0155] To facilitate explanation of the solution in the embodiment of the present application, the following explanation is given by taking the source base station determining that the terminal should be switched as an example, and the interaction steps involving candidate target base stations that are not target base stations are omitted.

[0156] Step 105: The source base station sends a handover request to the target base station.

[0157] The switching request carries calculation information.

[0158] It can be understood that in this step, the service base station of the terminal is the source base station. Therefore, the collaborative object of the terminal during collaborative computing is the source base station. The computing information carried in the switching request includes: one or more computing configuration information related to the computing tasks performed by the terminal during collaborative computing with the source base station.

[0159] In actual applications, the switching request may also carry configuration information related to the radio resource management (RRC, Radio Resource Control) connection. For example, the configuration information related to the RRC connection may include: the cell radio network temporary identifier (C-RNTI, Cell-Radio Network Temporary Identifier) ​​of the terminal in the source base station, the physical cell identifier (PCI, Physical Cell Identity) of the target cell, etc.

[0160] In the related technology, the switching request does not carry configuration information related to calculation, that is, it does not carry calculation information. Therefore, in the scenario where the terminal performs collaborative calculation with the source base station, when the service base station of the terminal is switched from the source base station to the target base station, the target base station cannot obtain the calculation information between the source base station and the terminal. For example, the target base station cannot obtain the calculation tasks that the terminal has unloaded from the source base station, which may cause the target base station to be unable to continue to perform collaborative calculation with the terminal, affecting the continuity of the calculation process.

[0161] In an embodiment of the present application, the switching request sent by the source base station to the target base station carries calculation information, so that the target base station can obtain the calculation information through the switching request. On this basis, the target base station can continue to perform collaborative calculations with the terminal, ensuring the continuity of the calculation process.

[0162] Step 106: The target base station allocates computing resources.

[0163] In actual applications, after receiving the handover request, the target base station may allocate computing resources based on the computing information carried in the handover request. The allocation of computing resources may include the following steps:

[0164] Step (1): The target base station determines, based on the calculation information, a calculation model on the base station side that needs to be adopted when performing collaborative calculation with the terminal.

[0165] Exemplarily, the target base station can determine the computing model on the base station side that matches the computing task by searching, based on the computing function and QoS parameters of the computing task related to the computing information, the list of computing models supported by the terminal, and the load, computing power and storage conditions of the target base station itself, and determine the computing model as the computing model that the target base station needs to adopt when performing collaborative computing with the terminal.

[0166] In actual applications, the target base station may also determine, based on the calculation information, a calculation file on the base station side that needs to be used when performing collaborative calculations with the terminal. The calculation file may also be referred to as a calculation model.

[0167] Step (2): The target base station allocates computing resources and storage space based on the QoS parameters of the computing tasks related to the computing information and the determined computing files and / or computing models on the base station side.

[0168] Furthermore, the management and allocation of computing resources and storage resources can be achieved by enhancing the management operations and maintenance (OM, Operations and Maintenance Link) function of the target base station, or by adding a computing resource management (CRM, Computing Resource Management) function to the base station.

[0169] Step 107: The target base station sends a handover response regarding the handover request to the source base station.

[0170] The switching response carries computing change information, and the computing change information includes: one or more computing configuration information that needs to be updated and / or added and / or deleted and is related to the computing task performed by the terminal in collaborative computing with the source base station.

[0171] In practical applications, the calculation change information can be understood as: one or more calculation configuration information that needs to be changed between the terminal and the target base station relative to the original calculation information in order to ensure that the collaborative calculation between the terminal and the target base station can achieve the original calculation target. Here, the original calculation target can be understood as: the calculation target when the terminal and the source base station perform collaborative calculations; the original calculation information can be understood as: the calculation information between the terminal and the source base station, that is, the calculation information carried in the handover request.

[0172] Therefore, the calculation change information can be used to update the original calculation information, and the updated calculation information can be used for the cooperative calculation between the terminal and the target base station.

[0173] It should be noted that, when the calculation information between the terminal and the target base station does not need to be changed relative to the original calculation information, the calculation change information can be empty, that is, the handover response can not carry the calculation change information. In this case, when the source base station receives the handover response, it is considered that the target base station knows the calculation information, or that the target base station can carry the relevant calculation tasks carried by the source base station.

[0174] In practical applications, after receiving the handover request, the target base station may determine the calculation change information based on the calculation information carried in the handover request. The calculation configuration information in the calculation change information may include: calculation files and / or calculation models and / or data collection configurations.

[0175] Exemplarily, the target base station can determine the computing model that the terminal needs to adopt when performing collaborative computing with the terminal based on computing information and its own load. If the determined computing model is inconsistent with the computing model currently used by the terminal, the configuration information of the determined computing model on the terminal side will be used as a computing configuration information that needs to be updated.

[0176] Exemplarily, the target base station can also determine, based on the calculation information and the data it needs, the data collection configuration that the terminal needs to adopt when performing collaborative calculations with the terminal. If the determined data collection configuration is inconsistent with the data collection configuration in the calculation information, the determined data collection configuration will be used as a calculation configuration information in the calculation change information.

[0177] Exemplarily, the target base station may also determine computing tasks that need to be added or deleted based on the computing information.

[0178] In the case where a new computing task needs to be added, the computing change information may include: one or more computing configuration information related to the computing task that needs to be added.

[0179] In the case where multiple computing tasks need to be added, multiple computing configuration information related to the multiple computing tasks that need to be added can form a list, each list item in the list corresponds to a computing task that needs to be added, and each list item can include one or more computing configuration information related to the corresponding computing task. The list can also be expressed as a new computing list.

[0180] In the case where a computing task needs to be deleted, the computing change information may include: one or more computing configuration information related to the computing task that needs to be deleted.

[0181] In the case where multiple computing tasks need to be deleted, multiple computing configuration information related to the multiple computing tasks that need to be deleted can form a list, each list item in the list corresponds to a computing task that needs to be deleted, and each list item can include one or more computing configuration information related to the corresponding computing task. For example, each list item only includes a task identifier of a computing task that needs to be deleted. The list can also be expressed as a deleted computing list.

[0182] Step 108: The source base station prepares a handover reconfiguration message.

[0183] Specifically, after receiving the handover request sent by the target base station, the source base station constructs a handover reconfiguration message to be sent to the terminal according to the calculation change information carried in the handover response.

[0184] The handover reconfiguration message may be used to instruct the terminal to reconfigure configuration information related to computing, that is, to update computing information.

[0185] In actual applications, the handover reconfiguration message may also be used to instruct the terminal to reconfigure configuration information related to the RRC connection.

[0186] Step 109: The source base station sends a handover reconfiguration message to the terminal.

[0187] Step 110: The terminal updates the calculation information based on the switching reconfiguration message.

[0188] In practical applications, the updated calculation information can be used for collaborative calculation between the terminal and the target base station.

[0189] Exemplarily, the terminal may update the data collection configuration based on the handover reconfiguration message, and the updated data collection configuration may enable the terminal to collect data required by the target base station during the process of cooperative calculation with the target base station.

[0190] In actual applications, the terminal may also reconfigure the configuration information related to the RRC connection based on the handover reconfiguration message.

[0191] In the related art, the handover reconfiguration message cannot be used to update the calculation information, resulting in that the target base station may not be able to continue to perform collaborative calculations with the terminal.

[0192] For example, if the data collection configuration indicates that the type of data collected by the terminal is the uplink and downlink rates when the terminal is performing collaborative computing with the source base station, and when the terminal is performing collaborative computing with the target base station, the type of data that the target base station requires the terminal to collect is CSI, then, since the switching reconfiguration message cannot be used to update the data collection configuration, after the service base station of the terminal is switched from the source base station to the target base station, the type of data collected by the terminal is still the uplink and downlink speeds, resulting in the terminal being unable to provide the target base station with the data required by the target base station, and further resulting in the terminal being unable to continue to perform collaborative computing with the target base station, affecting the continuity of the collaborative computing.

[0193] In the embodiment of the present application, a switching reconfiguration message is constructed and sent to the terminal based on the calculation change information carried in the switching response. Therefore, the switching reconfiguration message can be used for the terminal to update the calculation information, so that the terminal can perform collaborative calculation with the target base station, thereby ensuring the continuity of the calculation process.

[0194] Step 111: The terminal switches to the target base station and performs collaborative calculation with the target base station based on the updated calculation information.

[0195] In actual applications, after receiving the handover reconfiguration message, the terminal updates the calculation information, but before the serving base station is switched from the source base station to the target base station, it can still perform collaborative calculation with the source base station based on the calculation information before the update.

[0196] When the computing power of the terminal is sufficient, in order to ensure that the terminal can quickly perform collaborative calculations with the target base station after the service base station of the terminal is switched from the source base station to the target base station, in one embodiment, the terminal may also perform pre-calculations based on updated calculation information before the service base station is switched from the source base station to the target base station.

[0197] The following is a re-explanation of the overall interaction process of this solution, see Figure 2 ,The overall interaction process of this solution can include the following steps:

[0198] Step 201: The terminal and the source base station perform collaborative calculations.

[0199] Step 202: The source base station sends RRM measurement configuration to the terminal.

[0200] Step 203: The terminal reports the RRM measurement result to the source base station.

[0201] Step 204: The source base station makes a handover decision.

[0202] Step 205: The source base station sends a handover request to the target base station.

[0203] Step 206: The target base station allocates computing resources.

[0204] Step 207: The target base station sends a handover response regarding the handover request to the source base station.

[0205] Step 208: The source base station prepares a handover reconfiguration message.

[0206] Step 209: The source base station sends a handover reconfiguration message to the terminal.

[0207] Step 210: The terminal updates the calculation information based on the handover reconfiguration message.

[0208] Step 211: The terminal sends pre-calculated data to the source base station.

[0209] In actual applications, the terminal can perform computing tasks based on the updated computing information to obtain pre-computed data.

[0210] Step 212: The source base station forwards the pre-calculated data to the target base station.

[0211] In this step, the serving base station of the terminal has not yet been switched to the target base station, so the source base station needs to forward the pre-calculated data to the target base station.

[0212] In practical applications, forwarding of pre-calculated data by the source base station to the target base station can also be described as: the source base station forwards the data.

[0213] In actual applications, before the service base station of the terminal switches to the target base station, the target base station can first perform computing tasks based on pre-calculated data, which is equivalent to performing collaborative computing with the terminal in advance, thereby ensuring as much as possible that after the service base station of the terminal switches to the target base station, the target base station can seamlessly take over the computing tasks corresponding to the collaborative computing, further improving the continuity of the computing.

[0214] Step 213: The terminal accesses the target base station.

[0215] In this step, the serving base station of the terminal is switched from the source base station to the target base station. In practical applications, the terminal accessing the target base station can also be described as the terminal accessing the target cell in the target base station.

[0216] Step 214: The terminal performs collaborative calculation with the target base station.

[0217] In actual applications, after the terminal's service base station is switched from the source base station to the target base station, the terminal performs collaborative calculations with the target base station based on the updated calculation information. It can be understood that the terminal no longer needs to perform collaborative calculations with the source base station based on the calculation information before the update. Therefore, the terminal can delete the calculation information before the update.

[0218] In practical applications, Figure 2 Steps 201 to 210 in the embodiment can be understood with reference to the above-mentioned embodiment and will not be described in detail here.

[0219] In practical applications, in the open radio access network (O-RAN) scenario, a near-real-time radio access network intelligent controller (Near-RT RIC) can be introduced as a regional centralized control node of the radio access network (RAN) to achieve joint control of multiple base stations in the RAN area. The RAN area to which the regional centralized control node belongs can be regarded as the control area of ​​the regional centralized control node.

[0220] Based on this, in one embodiment, the devices participating in the interaction process of this solution also include: a regional centralized control node. The overall interaction process of this solution is described again below, see Figure 3 ,The overall interaction process of this solution can include the following steps:

[0221] Step 301: a source base station reports state information of the source base station to a regional centralized control node, and a target base station reports state information of the target base station to the regional centralized control node.

[0222] The status information may include: information describing the load and / or computing power and / or wireless channel status of the base station. The status information may be used by the regional centralized control node to determine a base station that meets the computing requirements of the terminal.

[0223] In actual applications, each base station within the control area of ​​the regional centralized control node can report its real-time status information to the regional centralized control node. Among them, the base station can report to the regional centralized control node through the enhanced E2 interface, and the enhanced E2 interface can support the reporting of status information.

[0224] In actual applications, after receiving the status information, the regional centralized control node can store the status information locally. The terminals in the control area of ​​the regional centralized control node can also report their own computing-related business information to the regional centralized control node.

[0225] Step 302: The terminal and the source base station perform collaborative calculations.

[0226] Step 303: The source base station sends RRM measurement configuration to the terminal.

[0227] Step 304: The terminal reports the RRM measurement result to the source base station.

[0228] Step 305: The source base station reports the RRM measurement result sent by the terminal to the regional central control node.

[0229] In actual applications, the source base station can report the RRM measurement results to the regional centralized control node through the E2 interface.

[0230] Step 306: The regional centralized control node makes a switching decision.

[0231] In actual applications, the regional centralized control node can determine a base station that meets the communication and computing requirements of the terminal according to the RRM measurement results and / or the status information reported by the base station, and determine the base station as the target base station for the terminal to switch.

[0232] In actual applications, after receiving the handover request, the target base station can also allocate communication resources.

[0233] Step 307: The regional centralized control node sends a handover indication message to the source base station.

[0234] In practical applications, the switching indication message is used to instruct to switch the serving base station of the terminal from the source base station to the target base station determined by the regional centralized control node. The switching indication message carries relevant information of the target base station, for example, the identifier of the target base station.

[0235] For ease of explanation, the target base station in this overall interaction process is also the target base station determined by the regional centralized control node.

[0236] Step 308: The base station sends a handover request to the target base station.

[0237] Step 309: The target base station allocates computing resources.

[0238] In practical applications, the target base station can also allocate communication resources.

[0239] Step 310: The target base station sends a handover response regarding the handover request to the source base station.

[0240] Step 311: The source base station prepares a handover reconfiguration message.

[0241] Step 312: The source base station sends a handover reconfiguration message to the terminal.

[0242] Step 313: The terminal updates the calculation information based on the switching reconfiguration message.

[0243] Step 314: The terminal sends the pre-calculated data to the source base station.

[0244] Step 315: The source base station forwards the pre-calculated data to the target base station.

[0245] Step 316: The terminal accesses the target base station.

[0246] Step 317: The target base station sends status information to the regional centralized control node.

[0247] Step 318: The source base station sends status information to the regional centralized control node.

[0248] In practical applications, there is no restriction on the execution order of step 317 and step 318, and they can also be executed simultaneously.

[0249] In actual applications, after receiving the status information reported by the source base station and the target base station, the regional centralized control node may update the status information stored locally in the regional centralized control node, thereby ensuring the real-time performance of the stored status information.

[0250] Step 319: The terminal performs collaborative calculation with the target base station.

[0251] In practical applications, Figure 3 Steps 302 to 304, steps 308 to 316, and step 319 in the embodiment can be understood with reference to the aforementioned embodiments and will not be described in detail here.

[0252] In the embodiment of the present application, each base station within the control area of ​​the regional centralized control node reports status information to the regional base station control node. The status information can be used by the centralized control node to determine the base station that meets the computing requirements of the terminal during the switching process. Therefore, the regional centralized control node in the embodiment of the present application can determine the target base station that matches the computing requirements of the terminal, thereby ensuring the collaborative computing between the terminal and the target base station as much as possible, thereby improving the continuity of the computing.
