Communication method, communication device, and communication system

Abstract

The present disclosure relates to the technical field of communications, and provides a communication method, a communication device, and a communication system. When a computing power node has insufficient computing power resources and needs to transfer a connected terminal to another computing power node, and when the transfer process requires serving cell handover for the terminal, the computing power node sends, to a network device, first information for requesting the network device to perform cell handover for the terminal, and the network device performs a corresponding operation on the basis of the request. Thus, handover from the computing power node to a serving cell can be coordinately controlled, thereby enabling the terminal to achieve coordinated handover between the computing power node and the cell.

[0025] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and are not to be understood as limiting the present disclosure. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0026] For ease of understanding, first introduce the terms related to the embodiments of the present disclosure.

[0027] 1. Artificial intelligence (AI)

[0028] Machine learning algorithm is one of the most important implementation methods of artificial intelligence technology. Machine learning can obtain an AI model through a large amount of training data, and through the AI model, events can be predicted. In many fields, the AI model trained by machine learning can obtain very accurate prediction results.

[0029] Wireless communication networks can use AI functions for prediction and inference to improve system performance. An AI function implements a specific function, which can include one or more AI models. The training of an AI model requires the collection of a large amount of data, and different application scenarios require different data. Application scenarios can include beam management, channel state information (CSI) reporting, CSI compression, positioning, handover, mobility management, and wireless resource management, etc. mobile communication system processes.

[0030] 2. Computing power node

[0031] Computing power is the ability of a node with computing power in a network to achieve a specific result output through data processing. Computing power resources specifically include, but are not limited to, computing, reading and writing, storage, algorithms, AI models, AI inference, AI training, AI verification, and data distribution. On the network side, especially in mobile communication networks, computing power nodes refer to entities that can provide computing resources and are responsible for managing and allocating these resources. The computing power of the terminal is limited and cannot support services that require high computing power. Network nodes can share computing power with terminals to help terminals perform calculations. On the network side, computing power is managed through computing power nodes, which are responsible for the allocation, scheduling, activation, control, and distribution of computing power. As shown in FIG. 1, each computing power node can be connected to one or more base stations. The terminal (UE) is connected to the computing power node through the base station. The UE can request computing power resources from the computing power node.

[0032] 3. Cell handover

[0033] During cell handover, the network configures the terminal to perform measurements. Based on the measurement results reported by the terminal, the network sends a handover request to the target cell. After the target cell is confirmed, the network sends a handover command (Reconfiguration with sync) to the terminal, carrying configuration information of the target cell. This configuration information may include bearer configuration, Media Access Control (MAC) configuration, and random access configuration. After receiving the handover command, the terminal synchronizes with the target cell, then initiates a random access procedure to access the target cell and begins using the target cell's configuration.

[0034] To shorten the handover process time, a low-level triggered mobility procedure (L1 / L2 Triggered Mobility, LTM) is introduced. The network can send the configurations of multiple target cells to the terminal in advance (carried through ltm-CandidateConfig), and the terminal stores these configurations. The network can send an LTM Cell Switch Command MACCE to the terminal, indicating the target cell. After receiving the LTM Cell Switch Command MACCE, the terminal uses the stored corresponding configuration to initiate a handover to the target cell.

[0035] During cell handover, after receiving the handover command, the terminal disconnects from the source cell and initiates a random access procedure to the target cell. Before successfully establishing a connection with the target cell, data transmission and reception are interrupted, causing service latency. To achieve zero latency during handover, a Dual Active Protocol Solution (DAPS) solution is introduced.

[0156] When the computing power resources of the computing power nodes providing services for the terminals are insufficient or need to be maintained, it is necessary to transfer the connected terminals to other computing power nodes, and the service cells of the terminals need to be switched during the transfer process. However, there is currently a lack of effective means for coordinating and controlling the computing power nodes and the service cell switching.

[0157] To solve the above problems, by applying the scheme of the embodiments of the disclosure, when the computing power resource of the computing power node is insufficient, the connected terminal needs to be transferred to other computing power nodes, and the service cell of the terminal needs to be switched during the transfer process, the computing power node sends first information to the network device, to request the network device to perform cell switching of the terminal, and the network device performs corresponding operations according to the request, to coordinate and control the switching of the computing power node and the service cell, and thus the terminal can realize coordinated switching between the computing power node and the cell.

[0158] Further, in order to illustrate the specific execution process of the above communication system, FIG. 3 shows a schematic diagram of a communication method according to an embodiment of the disclosure. The method is applied to the above communication system, as shown in FIG. 3, and can include the following steps:

[0159] In step S201, the computing power node sends first information to the network device.

[0160] In some embodiments, the first information can be used to request the network device to perform cell switching of the terminal.

[0161] In some examples, the computing power node can be responsible for management, allocation, scheduling, activation and control of the computing power resource.

[0162] In some examples, the network device can be a network device to which the terminal is currently connected, such as a base station to which the terminal is currently connected.

[0163] In some examples, the computing power node can be a computing power node to which the terminal is currently connected, such as a computing power node to which the terminal is connected through the network device, and the computing power node can provide the terminal with computing power resources.

[0164] In some embodiments, the computing power node can receive node information of a candidate computing power node sent by the terminal, and in some examples, the node information can include information for identifying the candidate computing power node, and / or information for identifying a cell connected by the candidate computing power node, such as a service cell corresponding to a network device connected by the candidate computing power node.

[0165] In some embodiments, the terminal can send a first identifier to the computing power node, and the first identifier can be used to identify the terminal. In some examples, the first identifier can be a C-RNTI, i.e., a cell radio network temporary identifier, which can be allocated by the network device to the terminal for uniquely identifying the terminal within the cell.

[0166] In some embodiments, the computing power node determines the second identifier according to the node information of the candidate computing power node, and the second identifier can be used to identify the candidate cell. The candidate computing power node can be a computing power node capable of providing terminal computing power resources. When the computing power resources of the computing power node are insufficient, or need to be maintained, or need to be upgraded, the computing power node capable of continuing to serve the terminal can be selected from the candidate computing power nodes, and the second identifier of the candidate cell is determined according to the cell connected by the selected computing power node, that is, the current cell of the terminal needs to be switched to the target cell in the candidate cell. The computing power node can instruct the network device to perform switching according to the information.

[0167] In some examples, the computing power node determines the second identifier according to the node information of the candidate computing power node, including: determining a first computing power node from the candidate computing power nodes according to the required computing power of the terminal and the capabilities of the candidate computing power nodes, the first computing power node being a computing power node whose capabilities can meet the required computing power of the terminal; and determining the second identifier according to the cell connected by the first computing power node, the second identifier being used to identify the candidate cell.

[0168] In some embodiments, the first information includes at least one of A1 to B1 below:

[0169] A1, the first identifier, which can be used to identify the terminal, so that the network device can determine the terminal that needs to be switched.

[0170] B1, the second identifier, which can be used to identify the candidate cell, and the second identifier can be one or more, that is, the second identifier corresponding to one or more candidate cells, so that the network device judges the candidate cells, and then determines whether there is a candidate cell that can be switched.

[0171] C1, the first duration, which can be used to determine the maximum duration of service interruption. If switching causes service interruption, the first information can carry the first duration in this embodiment, which is used to determine the maximum allowed duration of service interruption, so as to facilitate the network device to judge the candidate cell as a reference. According to the maximum duration, it is determined whether the candidate cell can meet, that is, on the premise that the switching time does not exceed the maximum duration, it is judged whether the switching time generated by switching to the candidate cell is less than or equal to the maximum duration, and then it is determined whether the candidate cell can be switched.

[0172] In some embodiments, the computing power node can determine the first duration according to the quality of service (QoS) of the service, i.e., determine the maximum duration of service interruption. The embodiments of the present disclosure can determine the maximum duration of service interruption that can be accepted based on the quality requirements of the service. QoS is a set of standards for measuring the quality of service, which can involve multiple aspects, including delay, packet loss rate, bandwidth guarantee, throughput, etc., and needs to consider the requirements of the service, technical limitations, and the feasibility of actual operation. This helps to ensure the stability and reliability of the computing power service, thereby meeting the expectations of users.

[0173] In some embodiments, the network device receives the first information sent by the computing power node.

[0174] Step S202, the network device determines whether the terminal can be switched to the candidate cell according to the first information.

[0175] If the terminal can be switched to the candidate cell, the second information is sent to the computing power node; if there is no candidate cell that the terminal can be switched to, the third information is sent to the computing power node. Specifically, the processes shown in steps S203a or S203b can be performed.

[0176] In some embodiments, the network device determines whether the terminal can be switched to the candidate cell according to the first information, including: determining that the candidate cell meets the requirement of the maximum duration of service interruption, such as that the switching time generated by switching to the candidate cell is less than or equal to the maximum duration; and sending a switching request to the first network device of the candidate cell, the switching request carrying the first identifier, for requesting whether to agree to switch the terminal to the candidate cell; if a switching confirmation message returned by the first network device is received, it means that the other party agrees to switch the terminal to the candidate cell, and then the terminal is determined to be switchable to the candidate cell according to the switching confirmation message.

[0177] Further, in some examples, if it is determined that all candidate cells cannot meet the requirement of the maximum duration of service interruption, such as that the switching time generated by switching to the candidate cell is greater than the maximum duration, it can be determined that there is no candidate cell that the terminal can be switched to; or if the network devices of these candidate cells are sent switching requests, and these candidate cells do not agree to switch the terminal to the candidate cell, it can be determined that there is no candidate cell that the terminal can be switched to.

[0178] Step S203a, the network device sends the second information to the computing power node in the case that the terminal is determined to be switchable to the candidate cell.

[0179] In some embodiments, the computing power node can receive the second information sent by the network device.

[0181] A2, confirmation information, the confirmation information can be used to confirm that the terminal can switch to the candidate cell, for example, when there is only one second identifier of the candidate cell in the first information, one bit can be used to indicate the confirmation information, such as 0 or 1.

[0182] B2, third identifier, the third identifier can be used to identify the candidate cell to which the terminal can switch, and the third identifier can be one or more, that is, one or more candidate cells to which the terminal can switch respectively correspond to the third identifier, for example, the network device further filters out the candidate cell to which the terminal can switch from B1 through judgment.

[0183] C2, second duration, the second duration can be used to determine the interruption duration of the terminal switching to the candidate cell. In some examples, when the terminal can switch to multiple candidate cells, the second information can be used to respectively indicate the second duration corresponding to each of the candidate cells.

[0184] In some embodiments, the computing node selects the switching target cell of the terminal from the candidate cell of B2 according to the second duration of C2. For example, the corresponding candidate cell with the minimum duration in C2 is selected as the switching target cell of the terminal.

[0185] In some embodiments, the computing node sends a switching indication to the network device to indicate switching, and correspondingly, in some examples, the network device receives the switching indication sent by the computing node; wherein the switching indication comprises at least one of the following A3 to D3:

[0186] A3, first identifier, the first identifier can be used to identify the terminal, which can be the same as the first identifier of A1.

[0187] B3, fourth identifier, the fourth identifier is used to identify the switching target cell of the terminal, and in some examples, the switching target cell can be the cell selected by the computing node from the candidate cell of B2.

[0188] C3, first duration, the first duration is used to determine the maximum duration of service interruption, which can be the same as the first duration of C1.

[0189] D3, a first command, the first command is used to instruct the terminal to switch the computing power node, and the first command can be a computing power node switching command. In some examples, the first command can carry an identifier of a second computing power node to which the terminal switches. The second computing power node is a computing power node in the candidate computing power node, and further, the second computing power node is a computing power node whose capability can meet the required computing power of the terminal, and the cell connected by the second computing power node can be a cell corresponding to the fourth identifier.

[0190] In some embodiments, the network device sends a switching command to the terminal according to the switching instruction; wherein the switching command is used to instruct the terminal to switch to a target cell, and the target cell is a cell corresponding to the fourth identifier of B3.

[0191] In some embodiments, the switching command can carry the first command of D3, which is used to instruct the terminal to switch the computing power node. After receiving the first command, the terminal switches the computing power service to the second computing power node.

[0192] In some embodiments, the network device can determine the manner of terminal cell switching according to the maximum time length (the first time length of C3) of service interruption, so that the time of terminal cell switching is as small as possible or less than or equal to the maximum time length, such as using a dual active protocol stack solution (DAPS), a mobility flow (LTM) or a traditional switching.

[0193] Step S203b parallel to step S203a, the network device sends third information to the computing power node in the case where it is determined that there is no candidate cell that the terminal can switch to.

[0194] In some embodiments, the third information is used to determine that there is no switchable cell.
