Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, and in particular to a load balancing processing method and device and network equipment. BACKGROUND

[0002] With the deployment of ultra-dense cells and user mobility, there is a phenomenon of frequent user switching and load imbalance, which leads to the decline of network performance and the reduction of user satisfaction.

Obviously, the described embodiments are only part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0166] In the present application, the cell load can be represented by resource block utilization ratio (RBUR). For example, the resource block utilization ratio is the ratio of the actual number of resource blocks (RB) used by the cell to the number of RBs available to the cell. For a given time duration T, the average load of cell i at time t is:

[0167]

[0168] wherein, is the average load of cell i at time t, N PRB is the number of RBs available in the system, is the actual number of RBs used by the cell.

[0170]

[0171] wherein, is the average load of the network, N is the number of cells.

[0173]

[0174] wherein, is the standard deviation of the network.

[0175] Considering the minimization of the standard deviation of the network load while satisfying the limit of the number of RBs, the form is as follows:

[0176]

[0177]

[0178] When there is load imbalance between cells, it is necessary to adjust the cell load through handover implementation, mainly according to the A3 event in LTE. When the A3 event continuously meets the trigger condition within the Time To Trigger (TTT), the handover operation is performed. The trigger condition of the A3 event is as follows:

[0179] Mn+Ofn+Ocn-Hyst>Mp+Ofp+Ocp+Off

[0180] Wherein, Mn and Mp represent the average received signal strength of the target cell and the source cell, Ofn and Ocp represent the frequency offset of the target cell and the source cell, Ocn and Ocp represent the cell independent offset of the target cell and the source cell, Hyst is a hysteresis parameter, and Off is the A3 event offset of the source cell and the target cell.

[0181] The selection of the handover user is determined by the A4 event, and the trigger condition is as follows:

[0183] The whole load balancing process is as follows. First, collect the A3 event measurement report of each cell. If the cell meets the condition within the TTT time, select the handover user according to the A4 event, indirectly change the cell coverage range by modifying the cell relative offset (CIO) and the hysteresis parameter Hyst, etc., so that the users in the edge channel quality of the high load cell can be handed over to the adjacent cell with better channel condition and load state, thereby relieving the inter-cell load imbalance and minimizing the network load standard deviation.

[0184] However, the above handover method is performed after detecting the load imbalance, and it is necessary to continuously observe the TTT time. The service quality of the user will continue to deteriorate before the handover, thereby increasing the user interruption rate. When the user moves between cells with different load degrees, the user will be frequently handed over between cells, which produces a ping-pong effect during the movement of the user, increases the handover time and delay, and if the user experiences multiple handovers, the handover delay will be accumulated, thereby seriously damaging the user experience.

[0185] Embodiments of the present application provide a load balancing processing method and device and network equipment to solve the problem that the current load balancing handover strategy is performed after detecting the load imbalance, which may cause the service quality of the user to continue to deteriorate before the handover, thereby increasing the user interruption rate.

[0186] The method, the device and the network equipment are based on the same application concept, and the implementation of the method, the device and the network equipment can be referred to each other because the principles of solving problems are similar, and the repeated parts will not be described in detail.

[0187] As shown in Figure 1 The embodiment of the application provides a load balancing processing method, which specifically comprises the following steps:

[0188] Step 11: The network equipment predicts a first cell to which the terminal will move after a first time point.

[0189] Optionally, the first time point can be a current time point or a time point after the current time point.

[0190] Step 12: The network equipment predicts a first load of the first cell and a second load of a second cell in the case that the terminal moves to the first cell; wherein the first cell is adjacent to the second cell.

[0191] Step 13: The network equipment performs load balancing processing if it is determined that the trigger condition of load imbalance between the first cell and the second cell is met according to the first load and the second load.

[0192] In the embodiment, the network equipment performs load balancing processing when it is determined that load imbalance will occur between the first cell and the second cell after the first time point according to the first load of the first cell and the second load of the second cell in the case that the terminal moves to the first cell, so that the problem that the service quality of the user will continuously deteriorate before switching when the load imbalance is detected at present, thereby causing the increase of the user interruption rate, is solved.

[0193] Optionally, the network equipment predicting the first cell to which the terminal will move after the first time point comprises:

[0194] The network equipment predicts a second moving track of the terminal after the first time point according to a first moving track of the terminal before the first time point;

[0195] The network equipment predicts the first cell to which the terminal will move after the first time point according to the second moving track.

[0196] For example: at each time point t, the base station predicts the first cell to which the terminal will move after the time point t according to the first moving track of the terminal in the past T h time (i.e. T ha moving trajectory of the terminal in a time period, i.e. a first moving trajectory (here the moving trajectory can be understood as geographical positions of the terminal at multiple time instants respectively), predicts a moving trajectory of the terminal in a future T p a time period, i.e. a second moving trajectory. p a time period, i.e. a second moving trajectory.

[0197] As shown in Figure 2 , the prediction contains a history window and a prediction window, where a time sequence from t r to t p is called a history window, and the window length is T h =t p -t r , containing positions on the moving trajectory of the terminal. The sequence of the history window trajectory is denoted as x His (t)=[x(t-M+1),…,x(t)] T . A time sequence from t p to t q is called a prediction window, and the window length is T p =t q -t p . The prediction window contains positions on the moving trajectory of the terminal, denoted as x Pre (t)=[x(t+1),…,x(t+N)] T . x(t) = (a(t), b(t)) is the position of the user at time instant t, and a(t) and b(t) represent the position coordinates in the horizontal direction and the vertical direction respectively.

[0198] As shown in Figure 3 , the moving trajectory of the terminal can be predicted by a deep neural network, which contains two processes of offline training and online prediction. For example, the moving trajectory of the terminal in a research scenario can be collected as a sample to train the neural network, and after the training is completed, the online prediction stage can be entered. In online prediction, the terminal can upload its corresponding position information in real time, and the predictor can predict the future moving trajectory according to the historical information (i.e. the position information uploaded in real time) uploaded by the terminal.

[0199] Optionally, the network device predicts a first cell to which the terminal is to be moved after the first time instant according to the second moving trajectory, including:

[0200] The network device determines a channel gain corresponding to the second moving trajectory of the terminal according to a channel information table; wherein the channel information table is used to indicate channel information values of the terminal at different positions;

[0201] The network device predicts a first cell to which the terminal is to be moved after the first time according to the channel gain.

[0202] For example, the predicted moving track after the first time (i.e., the second moving track) and the signal map (Radio Map) can be used to obtain the predicted value of the large-scale channel gain. The signal map (i.e., the channel information table) can be measured and stored by the base station in advance, which can represent the large-scale channel information value (e.g., including path loss and shadow fading) of the terminal accessing the base station at each position. In this way, the large-scale channel information of the terminal can be obtained by combining the predicted moving track of the terminal with the signal map, and then the moving direction of the terminal in the prediction window can be determined according to the large-scale channel information of the terminal in the prediction window. The moving direction can be understood as the direction in which the terminal moves towards the first cell, i.e., the first cell to which the terminal is to be moved. For example, in the case of continuously increasing large-scale channel information from the target base station to the terminal, it can be determined that the terminal moves towards the target cell, i.e., the moving direction of the terminal.

[0203] Optionally, the network device predicts the load of the first cell and the second cell in the case that the terminal moves to the first cell, including:

[0204] The network device determines the first load of the first cell by predicting the number of resources required by the terminal in the first cell in the case that the terminal moves to the first cell, and the total number of available resources of the system.

[0205] The network device determines the second load of the second cell by predicting the number of resources required by the terminal in the second cell in the case that the terminal moves to the first cell, and the total number of available resources of the system.

[0206] For example, the large-scale channel information of the terminal on the second track (i.e., the large-scale channel information of the terminal in the prediction window) and the terminal demand are used to estimate the load of the cell after the first time (i.e., the future time). The number of resources required by the terminal in each cell can be used to measure the load of each cell, wherein the number of resources required by the terminal is related to the terminal demand in the cell and the channel information of the terminal. The base station accessed by the terminal and the number of resources required by the terminal can be determined by the predicted position (i.e., the moving track) of the terminal and the predicted large-scale channel gain of the terminal at the corresponding position, so as to predict the load of the cell.

[0207] Optionally, the network device determines that the trigger condition of load imbalance is met between the first cell and the second cell according to the first load and the second load, and performs load balancing processing, including:

[0208] If the network device determines that the first cell and the second cell satisfy the triggering condition of load imbalance at the second time according to the first load quantity and the second load quantity at the second time after the first time, the network device determines whether the first cell and the second cell both satisfy the triggering condition of load imbalance in a first time period starting from the second time according to the first load quantity and the second load quantity at the second time.

[0209] If the network device determines that the first cell and the second cell both satisfy the triggering condition of load imbalance in the first time period, the network device performs load balancing processing.

[0210] For example, if it is predicted that the first cell and the second cell satisfy the triggering condition of load imbalance at t+i (i.e., the second time) at time t (e.g., the first time), the prediction result after t+i is observed, and the observation time is TTT. If the first cell and the second cell both satisfy the triggering condition of load imbalance in a first time period from t+i to t+i+TTT, it is determined that the load imbalance occurring at t+i needs to be processed, so that the load balancing processing does not need to wait until after t+i+TTT, as shown in FIG. 4, i.e., the problem that the service quality of users continues to deteriorate before switching is performed, thereby increasing the user interruption rate, is solved. Figure 4

[0211] Optionally, if the network device determines that the first cell and the second cell satisfy the triggering condition of load imbalance according to the first load quantity and the second load quantity, the network device performs load balancing processing, including:

[0212] If the network device determines that the first cell and the second cell satisfy the triggering condition of load imbalance at the second time according to the first load quantity and the second load quantity at the second time after the first time, the network device determines the user type to which the terminal belongs by predicting the received signal strength of the terminal, wherein the user type includes a center user and an edge user.

[0213] The network device performs load balancing processing according to the user type.

[0214] For example, after it is predicted that the first cell and the second cell satisfy the triggering condition of load imbalance at t+i at time t, the user type of the terminal is divided to determine whether the user type to which the terminal belongs is a center user or an edge user. Load balancing processing is performed according to the user type to which the terminal belongs, so that the cell load balancing can converge faster and more effectively.

[0215] ​Optionally, the user type of the terminal is determined based on the received signal strength corresponding to the terminal, including:

[0216] Predict the first received signal strength of the terminal in the first cell, and the second received signal strength of the terminal in the second cell;

[0217] If the difference between the first received signal strength and the second received signal strength is greater than a first threshold, then the user type of the terminal is determined to be a central user.

[0218] If the difference between the first received signal strength and the second received signal strength is less than or equal to the first threshold, then the user type of the terminal is determined to be an edge user.

[0219] For example, the average channel gain difference between two adjacent cells (which can also characterize the difference in received signal strength between two adjacent cells) is used to classify the user type of a terminal. For a terminal UE... k In this regard, the channel gain difference between two adjacent cells can be expressed as:

[0220]

[0221] in, For the terminal UE k The channel gain difference between two adjacent cells For the terminal UE k To the community BS i Channel gain, For the terminal UE k To the community BS j Channel gain.

[0222] Terminal UE k The user type classification can be determined based on the difference in channel gain, if the terminal UE k corresponding If the value exceeds a given threshold, then the terminal UE will be... k They are classified as central users, otherwise as peripheral users.

[0223] Optionally, the network device performs load balancing processing based on the user type, including:

[0224] For a first terminal whose user type is a central user, the network device determines to maintain the connection between the first terminal and the first cell;

[0225] For a second terminal whose user type is an edge user, the network device determines the priority of the second terminal and performs cell handover for the second terminal according to the handover policy corresponding to the priority.

[0226] For example, for a first terminal with a user type of a central user, the first terminal will connect to a base station according to a maximum received signal strength, without performing handover. For a second terminal with a user type of an edge user, cell handover needs to be performed. Specifically, different strategies can be adopted for cell handover according to the corresponding priority of the second terminal, so as to reduce frequent handover and ping-pong effect existing in the process of terminal moving between cells, reduce the interruption probability of the terminal, and improve the throughput of the system.

[0227] Optionally, for the second terminal with the user type of the edge user, the network device determines the priority corresponding to the second terminal, including:

[0228] If a moving direction of the second terminal to be moved to the first cell is from a high-load cell to a low-load cell, the network device determines that the second terminal corresponds to a first priority;

[0229] If the moving direction of the second terminal is from a low-load cell to a high-load cell, the network device determines that the second terminal corresponds to a second priority;

[0230] If the moving direction of the second terminal is from a low-load cell to a low-load cell, or the moving direction is from a high-load cell to a high-load cell, the network device determines that the second terminal corresponds to a third priority.

[0231] The high-load cell is a cell with a resource occupancy ratio (or load) higher than or equal to a set threshold, and the low-load cell is a cell with a resource occupancy ratio lower than the set threshold.

[0232] For example, the second terminal with the user type of the edge user can be further divided according to the moving direction of the terminal obtained by the above prediction: when the second terminal moves from a high-load cell to a low-load cell, the second terminal is divided into an early handover user (i.e., a terminal of the first priority); when the second terminal moves from a low-load cell to a high-load cell, the second terminal is divided into a late handover user (i.e., a terminal of the second priority); and when the second terminal moves between cells with similar load (e.g., from one high-load cell to another high-load cell, or from one low-load cell to another low-load cell), the second terminal is divided into a normal handover user (i.e., a terminal of the third priority).

[0233] Optionally, the cell handover of the second terminal is performed according to a handover strategy corresponding to the priority, including:

[0234] According to the priority of the second terminal, a handover trigger threshold corresponding to the priority is determined.

[0235] If it is predicted that the difference between the receiving signal strengths of the second terminal in the first cell and the second cell reaches the handover triggering threshold in the second time period, the second terminal is handed over.

[0236] Optionally, the first handover triggering threshold is less than the third handover triggering threshold, and the second handover triggering threshold is greater than the third handover triggering threshold.

[0237] The first handover triggering threshold corresponds to the first priority, the second handover triggering threshold corresponds to the second priority, and the third handover triggering threshold corresponds to the third priority.

[0238] For example, for the second terminals of different priorities, different handover triggering thresholds are used to determine whether the second terminals meet the conditions for cell handover. As an implementation, for the terminals of the third priority (i.e., normal handover users), the corresponding handover triggering threshold can be set as the traditional handover decision threshold. For the terminals of the first priority (i.e., early handover users), the corresponding handover triggering threshold can be set as a threshold less than the traditional handover decision threshold (i.e., the first handover triggering threshold is less than the third handover triggering threshold). For the terminals of the second priority (i.e., late handover users), the corresponding handover triggering threshold can be set as a threshold greater than the traditional handover decision threshold. Of course, the handover triggering thresholds corresponding to different priorities can also be set according to terminal requirements, and the embodiments of the present application are not limited in this regard.

[0239] Optionally, after determining that a terminal meets the corresponding handover triggering threshold according to the handover triggering threshold corresponding to the terminal, in order to avoid ping-pong effect, it is predicted whether the terminal continuously meets the corresponding handover triggering threshold in the next TTT time period (i.e., the second time period) starting from the time when it is predicted that the terminal meets the corresponding handover triggering threshold. The handover triggering threshold can be a threshold of the difference between the receiving signal strengths of the terminal in adjacent cells, i.e., whether the difference between the receiving signal strengths of the terminal in adjacent cells meets the handover triggering threshold. If the terminal continuously meets the corresponding handover triggering threshold in the TTT time period, it is predicted that the terminal needs to be handed over. Otherwise, the terminal will continue to maintain the original connection state. In this way, if the cell handover operation is performed according to the above method, some terminals belonging to edge users will be connected to a new base station, thereby determining the final connection state of the terminal. Optionally, the final connection state of the terminal can also be compared with the connection state of the previous frame to obtain whether the terminal is handed over in this frame.

[0240] Optionally, the second terminal is handed over according to the handover strategy corresponding to the priority, including:

[0241] determining a switching time corresponding to the priority according to the priority corresponding to the second terminal;

[0242] performing cell switching on the second terminal at the switching time.

[0243] Optionally, the first switching time is before a third switching time, and the second switching time is after the third switching time.

[0244] The first switching time is a switching time corresponding to the first priority; the second switching time is a switching time corresponding to the second priority; and the third switching time is a switching time corresponding to the third priority.

[0245] For example, for a terminal of the first priority (i.e., an early switching user), a time for performing cell switching can be set to be before a time t+i at which load imbalance is predicted; for a terminal of the second priority (i.e., a late switching user), a time for performing cell switching can be set to be after the time t+i at which load imbalance is predicted; and for a terminal of the third priority (i.e., a normal switching user), a time for performing cell switching can be set to be at the time t+i at which load imbalance is predicted. Specifically, if it is predicted at a current time t that there is load imbalance at a time t+i, for a terminal belonging to an early switching user, a switching time for performing cell switching will be before the time t+i; for a terminal belonging to a late switching user, a switching time for performing cell switching will be after the time t+i; and for a terminal belonging to a normal switching user, a switching time for performing cell switching will be at the time t+i.

[0246] Optionally, as an implementation manner, a deep neural network can be used to predict a switching time corresponding to a terminal, including two processes of offline training and online prediction. For example, training samples can be generated through historical data: historical channel information corresponding to a terminal in a research scene is collected as an input of a neural network, different switching times of early switching users and late switching users are obtained as outputs of a model, and the neural network is trained according to the generated training samples. After the training is completed, an online prediction stage can be entered. In online prediction, a terminal can upload real-time historical channel information, so that a predictor can predict a switching time for performing cell switching at a future time (i.e., after a first time) according to the historical channel information uploaded by the terminal.

[0247] Optionally, the cell switching based on the switching trigger threshold corresponding to different priorities and the cell switching based on the switching time corresponding to different priorities can be independent; or the cell switching based on the switching trigger threshold corresponding to different priorities can be further based on the switching time corresponding to different priorities. For example, when the deep neural network does not have enough training samples, the cell switching based on the switching trigger threshold corresponding to different priorities can be adopted, and the training samples of the deep neural network are generated according to the switching decision, and then when the generated training samples meet the demand of the training samples of the deep neural network, the deep neural network is trained according to the generated training samples, so as to predict the switching time corresponding to the terminal according to the trained deep neural network.

[0248] Optionally, the cell switching of the second terminal comprises:

[0249] predicting a third load amount of the first cell and a fourth load amount of the second cell in the case that the connection state of the second terminal with the first cell is switched to the connection state of the second terminal with the second cell;

[0250] if the load fluctuation amount between the third load amount and the fourth load amount is less than a second threshold, switching the connection state of the second terminal with the first cell to the connection state of the second terminal with the second cell.

[0251] For example, when it is predicted that part of the terminals need to be switched, the load state of the target cell to which the terminal is switched also needs to be considered. Optionally, the resources consumed after the user is switched to the target cell are estimated according to the predicted large-scale channel information, and then the load state of the target cell after the switching is estimated.

[0252] If the load fluctuation between the two cells after the switching is too large, the switching operation is not performed, and the switching is performed when the load fluctuation between the two cells after the switching is less than a given threshold (i.e. the second threshold). Before the time reaches the predicted switching time of the terminal, the terminal maintains the connection state with the source base station; when the time reaches the predicted switching time of the terminal, the source base station initiates the switching process, the source base station disconnects the connection with the terminal, and the user is forced to switch from the source cell to the target cell, so that the terminal maintains the connection state with the target base station. As shown in Figure 5 As shown in FIG. 6, the user type of UE1 is a lagging switching user, and before reaching the lagging switching point P4, it will maintain the connection with the low load cell; after reaching the lagging switching point, it will switch to the high load cell. The user type of UE2 is an early switching user, and before reaching the early switching point P2, it will maintain the connection with the high load cell, and after reaching the early switching point, it will switch to the low load cell.

[0253] Optionally, the method further comprises:

[0254] The network device determines the first resource number required by the central region of each cell according to the resource number required by each terminal in the system and the user type corresponding to the terminal;

[0255] The network device determines the first resource number as the total number of available resources corresponding to the terminal belonging to the central user in the cell;

[0256] The network device determines the total number of available resources corresponding to the terminal belonging to the edge user in the cell according to the first resource number, the total number of resources in the system and the number of cells in the system.

[0257] In this embodiment, on the basis of the division based on the above-mentioned user type, the bandwidth can also be allocated according to the user type. For example: in order to reasonably allocate the bandwidth, so that the central user and the edge user can be served, therefore, the bandwidth allocation can be realized according to the demand resource number of the central user and the edge user in proportion.

[0258] Optionally, the predicted large-scale channel gain value can estimate the average data rate of the user The minimum data rate requirement of the user is The resource number required by the user is :

[0259]

[0260] The RB resource of each region should meet the demand of all users in the region, wherein the resource number required by each region depends on the maximum value of the RB number required by a single user in the region and the average RB number required by all users. In this way, according to the RB number required by each user, the total RB number required by the central region and the edge region of the cell can be further obtained:

[0261]

[0262]

[0263] In this way, according to the total RB number m c required by the central region of the cell and the total RB number m e required by the edge region, the total available RB number of each terminal in the central region of the cell and the total available RB number of each terminal in the edge region can be determined, which are respectively:

[0264] N c = m c

[0265]

[0266] wherein N c is the total number of RBs available to each terminal in the center region, is the total number of RBs available to the terminals in the edge region, G is the number of cells, and N is the total number of RBs in the system.

[0267] As Figure 6 shown, the embodiment of the present application gives a framework diagram of a load balancing processing system, and the processing steps of the load balancing implemented by the system include: performing mobility prediction according to the historical moving trajectory of a terminal to determine a predicted moving trajectory based on machine learning; predicting the moving direction of the terminal according to the predicted moving trajectory, and predicting the predicted channel state of the terminal at a future time according to the predicted moving trajectory; estimating the predicted load of the cell at the future time according to the predicted channel state, and predicting the load balancing at the future time according to the predicted load, so as to realize that when the load imbalance is predicted, the terminal that needs to be switched can be actively switched at the switching time corresponding to the terminal.

[0268] In this way, the scheme realizes the prediction of the load of the cell at the future time by introducing the trajectory prediction and the moving direction prediction into the switching strategy of the load balancing, so as to realize the switching preparation before the load imbalance occurs, so as to be able to timely and effectively adjust the cell load; and on the basis of the predicted moving trajectory and the moving direction of the terminal, the different types of terminals can be actively switched at the time when the load balancing is predicted to be needed, so as to promote the autonomous and rapid convergence of the load balancing, and reduce the number of user ping-pong switching.

[0269] Compared with the traditional passive switching strategy, the scheme can actively switch based on the active switching strategy of machine learning, without the need to continue to wait for the duration of TTT after the load imbalance occurs, and then switch, so that more reasonable switching and faster switching speed can be obtained, seamless connection is realized, and the system can timely and effectively handle the inter-cell load imbalance problem.

[0270] Compared with the traditional switching strategy that only considers the cell load and the channel quality of the user, the scheme optimizes the switching time of different types of terminals by combining the switching self-optimization strategy of the terminal moving direction and the load balancing mechanism and reasonably dividing the users, can effectively reduce the frequent switching and ping-pong effect existing in the process of moving between cells, reduce the interruption probability of the user, and improve the throughput of the system.

[0271] The network device related to the embodiments of the present application can be a base station, which can include multiple cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names.

In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be geographically separated.

[0272] The terminal device can be a device providing voice and / or data connectivity to users, handheld devices with or without wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different, for example, in the 5G system, the terminal device can be called a user equipment (User Equipment, UE).
