These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Before introducing the embodiments of the present application, an application context of the embodiments of the present application is explained first:
at present, the information age has come, the total amount of data is explosively increased, and the demand of people for data information is increasing day by day. In order to meet the requirement of users for wireless communication, Long Term Evolution (LTE) has come, and the LTE project improves and enhances the air access technology of the third Generation mobile communication technology (3rd-Generation, 3G), and adopts Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) as the only standards for wireless network Evolution. The peak rates of 100Mbit/s at the downlink and 50Mbit/s at the uplink are provided under the frequency spectrum bandwidth of 20MHz, the performance of users at the edge of a cell is improved, the cell capacity is improved, and the system delay is reduced.
The multimedia service is a main potential service of future wireless mobile communication, needs to occupy a large amount of wireless channels and spectrum resources, and increases the burden of wireless access service in part of urban areas or hot cities. Because the user movement and service distribution are unbalanced in the area, a hot spot cell exists in the wireless communication system, and the communication resources are in a local shortage condition, so that the wireless access service performance of part of users is greatly reduced. In the hotspot cell, the service request is far above an acceptable level, so that a higher probability of blocking of the request occurs, while other cells of the wireless communication system have available resources to serve more users. Based on the problems, the method can adopt a load transfer mode to transfer excessive services in the hot cell to the cell with lighter service, and balance the load among the cells from a network layer, thereby improving the user experience in the hot cell or the congested cell, reducing the resource waste and optimizing the network performance.
At present, the following two methods are mainly used for realizing load balancing among cells with the same coverage:
1) and determining a cell with larger load and a cell with smaller load in the same coverage cell, and switching the terminal equipment occupying more PRBs in the cell with larger load into the cell with smaller load.
2) And determining the number of users and user identifications needing to be switched according to the overload users and the number of the overload users in the cell with larger load by using a related algorithm, and determining the cell with smaller load to which the users need to be switched according to the pre-acquired load budget, thereby completing the switching of the terminal equipment of the users.
However, in the above two prior arts, because the terminal device to be switched occupies more PRBs in the original cell, the user has better perception of using the network, and when switching to other cells with the same coverage, the quality of channels in other cells with the same coverage cannot be guaranteed, and there may be problems of poor perception of using the network and poor user experience.
In view of the above problems, the inventive concept of the present application is as follows: in a cell with a large load, the use perception of a terminal device occupying more PRBs is better, while the use perception of a terminal device having a large amount of data waiting for transmission and a low rate transmission efficiency is worse in a buffer of a base station (eNodeB). If the terminal equipment is used as the terminal equipment to be switched, after the terminal equipment to be switched is switched to other same coverage cells, the problem that the use perception of the network is poor after the terminal equipment is switched to other same coverage cells in the prior art can be solved due to the fact that the loads of the other same coverage cells are small, and therefore user experience is improved.
The load balancing method for the cells with the same coverage provided by the embodiment of the application can be applied to an application scenario diagram shown in fig. 1. Fig. 1 is a schematic view of an application scenario of a load balancing method for cells with same coverage provided in an embodiment of the present application, so as to solve the above technical problem. As shown in fig. 1, the application scenario may include: at least one base station (e.g., base station 11 and base station 12 in fig. 1), a server 13, and at least one terminal device (e.g., terminal device 14 and terminal device 15 in fig. 1).
In the embodiment of the present application, the dotted hexagonal area is a geographic area corresponding to a coverage cell, where terminal devices 14 and 15 exist in the geographic area, and the coverage cell shares two cells, and the base station 11 and the base station 12 respectively provide services for the two cells.
Illustratively, the two cells are cell 1 and cell 2, respectively, where the base station 11 provides service for the cell 1, and the terminal device in the cell 1 interacts with the base station 11; the base station 12 serves the cell 2, and terminal devices in the cell 2 interact with the base station 12.
In the above example, assuming that the terminal devices 14 and 15 are located in the cell 1, the loads of the cell 1 and the cell 2 are determined according to the PRB occupancy rates and/or the number of terminal devices of the cells 1 and 2, and the first cell and the second cell are determined according to the load sizes of the cell 1 and the cell 2, that is, the cell 1 is the first cell and the cell 2 is the second cell.
Further, according to the RSRP of the terminal devices 14 and 15, the amount of data to be transmitted and the corresponding data transmission rate cached in the base station are determined from the terminal devices 14 and 15, and assuming that the target terminal device is the terminal device 14, the terminal device 14 is switched to the cell 2, so as to achieve the purpose of reducing the load of the cell 1, thereby further improving the use perception of the terminal device 14 on the network.
In practical applications, since the terminal device is also a processing device with data processing capability, the server in the application scenario shown in fig. 1 may also be implemented by the terminal device. In the embodiments of the present application, the server and the terminal device for data processing may be collectively referred to as an electronic device. Optionally, in the embodiment of the present application, an execution subject of the load balancing method for the same coverage cell is taken as the electronic device
The technical solution of the present application will be described in detail below with reference to specific examples.
It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a flowchart illustrating a first embodiment of a load balancing method for cells with same coverage according to the present application. As shown in fig. 2, the method for balancing loads of cells in the same coverage area may include the following steps:
s21, determining the first cell and the second cell from the same coverage cell according to the PRB occupancy rate and/or the number of terminal devices of each cell in the same coverage cell.
Wherein the load of the first cell is greater than the second cell.
In an implementation manner, a cell in which the PRB occupancy rate in the same coverage cell is greater than the first occupancy rate and/or the number of terminal devices is greater than the first number of devices is determined as the first cell; and determining the cells with the PRB occupancy rate smaller than the second occupancy rate and/or the number of the terminal devices smaller than the second device number in the cells with the same coverage as the first cells.
The first occupancy rate is greater than the second occupancy rate, and the first equipment number is greater than the second equipment number.
For example, suppose that there are three cells in the same coverage cell, which are cells 1, 2 and 3, respectively, the occupancy rate of cell 1 is 90%, and the number of terminal devices is 1500; the occupancy rate of the cell 1 is 60%, and the number of the terminal devices is 800; the occupancy rate of the cell 1 is 30%, the number of terminal devices is 500, the first occupancy rate is 80%, the second occupancy rate is 50%, the number of first devices is 1000, and the number of second devices is 600. The occupancy rate of the cell 1 is greater than the first occupancy rate, and the number of the terminal devices is greater than the first number of the terminal devices, the cell 1 is determined as a first cell; and if the occupancy rate of the cell 3 is less than the second occupancy rate and the number of the terminal devices is less than the second number of the terminal devices, determining the cell 3 as a second cell.
In another implementation manner, the electronic device determines a cell with the largest PRB occupancy among the cells with the same coverage as a first cell, and determines a cell with the smallest PRB occupancy as a second cell.
In another implementation manner, the electronic device determines a cell with the largest number of terminal devices in the same coverage cell as the first cell, and determines a cell with the smallest number of terminal devices as the second cell.
The number of the first cells or the second cells may be 1 or more than 1, and the specific number needs to be determined according to an actual situation, which is not specifically limited in the embodiment of the present application.
S22, according to the RSRP of each terminal device in the first cell, the data volume to be transmitted and the corresponding data transmission rate which are cached in the base station, the target terminal device is determined from the terminal devices in the first cell.
In an implementation manner, the electronic device may determine, as the target terminal device, a first terminal device in the first cell, where RSRP is greater than a preset receiving power, and a data transmission duration is greater than a preset duration.
The data transmission duration can be calculated by the data amount to be transmitted buffered in the base station and the corresponding data transmission rate.
In another implementation manner, the electronic device may determine, as the target terminal device, the first terminal device whose RSRP is greater than the preset receiving power in the first cell, and whose data volume to be transmitted is cached in the base station is greater than the preset data volume, and whose data transmission rate is less than the preset transmission rate.
In another specific manner, the electronic device determines terminal devices with RSRP greater than a preset receiving power in the first cell as first terminal devices, and determines a target terminal device from the first terminal devices according to a data volume to be transmitted and a corresponding data transmission rate, which are cached in the base station by each first terminal device.
The method comprises the following steps of determining a target terminal device from first terminal devices according to the data volume to be transmitted and the corresponding data transmission rate of each first terminal device cached in a base station, wherein the data volume to be transmitted and the corresponding data transmission rate can be realized through the following modes:
1) the electronic equipment determines the data transmission duration required by each first terminal device according to the data volume to be transmitted cached in the base station by each first terminal device and the corresponding data transmission rate, and determines the first terminal device with the data transmission duration being greater than the preset duration as the target terminal device.
Wherein, can be represented by the formula: and T is the data volume to be transmitted/the data transmission rate cached in the base station, and the data transmission duration required by the terminal equipment is obtained, wherein T is the data transmission duration.
2) The electronic equipment determines the data transmission time length required by each first terminal equipment according to the data volume to be transmitted cached in the base station by each first terminal equipment and the corresponding data transmission rate, and then determines the first terminal equipment with the longest data transmission time length as the target terminal equipment.
3) After the electronic device determines the data transmission duration required by each first terminal device according to the data volume to be transmitted cached in the base station by each first terminal device and the corresponding data transmission rate, the data transmission duration can also be used as a priority evaluation factor of each first terminal device. The priority evaluation factor is used for evaluating the priority of each first terminal device, the higher the priority evaluation factor is, the higher the priority of the corresponding first terminal device is, the terminal device determines the first terminal device with the highest priority as the target terminal device, or determines the first terminal device with the priority exceeding the priority threshold as the target terminal device.
4) The electronic device determines the first terminal device with the data transmission rate less than the preset transmission rate as the target terminal device, wherein the data amount to be transmitted cached in the base station is greater than the preset data amount.
The number of the target terminal devices may be 1 or more than 1, and the specific number needs to be determined according to an actual situation, which is not specifically limited in the embodiment of the present application.
And S23, switching the target terminal equipment to the second cell.
In a specific implementation manner, assuming that the number of the target terminal devices is 1 and the number of the second cells is 1, the target terminal devices are directly switched to the second cells.
In another specific implementation manner, assuming that the number of the target terminal devices is 1 and the number of the second cells is greater than 1, the target terminal devices are switched to the cell with the minimum PRB occupancy or the minimum number of the terminal devices in the second cells.
In another specific implementation manner, assuming that the number of the target terminal devices is greater than 1 and the number of the second cells is greater than 1, the target terminal device is switched to the second cells according to the PRB occupancy or the number of the terminal devices in each second cell.
For example, assuming that the number of target terminal devices is 5 and the number of second cells is 2, where the number of terminal devices of cell 1 in the second cell is 1000 and the number of terminal devices of cell 2 is 999, 2 target terminal devices are switched to cell 1 in the second cell, and 3 target terminal devices are switched to cell 2 in the second cell.
For example, assuming that the number of the target terminal devices is 6 and the number of the second cells is 2, the target terminal devices may be equally allocated to each second cell, that is, 3 target terminal devices are handed over to one of the second cells, and the other 3 target terminal devices are handed over to the other one of the second cells.
According to the load balancing method for the same coverage cell, a first cell and a second cell are determined from the same coverage cell according to the PRB occupancy rate and/or the number of terminal devices of each cell in the same coverage cell, a data volume to be transmitted and a corresponding data transmission rate which are cached in a base station are determined from the terminal devices in the first cell according to the RSRP of each terminal device in the first cell, and the target terminal devices are switched to the second cell. By switching the terminal equipment with larger data volume to be transmitted and lower data transmission rate cached in the base station to the cell with smaller load, the use perception of the low-rate terminal equipment with high speed requirement but not distributed to enough PRBs can be rapidly improved, and the load of the first cell is reduced.
Optionally, in some embodiments, before S21, the method for load balancing between co-coverage cells further includes: and acquiring the PRB occupancy rate of each cell in the covered cell according to a preset frequency.
Fig. 3 is a flowchart of a second embodiment of a load balancing method for co-coverage cells according to an embodiment of the present application, where as shown in fig. 3, the load balancing method for co-coverage cells may include the following steps:
s31, determining a first cell and a second cell which need to be subjected to load balancing processing according to the PRB occupancy rate of each cell in the same coverage cell and the number of terminal devices.
S32, determining first terminal equipment from the terminal equipment in the first cell according to the RSRP and the preset receiving power of each terminal equipment in the first cell, and obtaining the priority of each first terminal equipment according to the data volume to be transmitted and the corresponding data transmission rate of each first terminal equipment, wherein the data volume to be transmitted is cached in the base station.
S33, the first terminal device with the higher priority is switched to the second cell according to the priority of each first terminal device.
The high priority level indicates that the first terminal device has a large amount of data to be transmitted buffered in the base station and a low data transmission rate.
The following are embodiments of the apparatus of the present application that may be used to perform embodiments of the method of the present application. For details which are not disclosed in the embodiments of the apparatus of the present application, reference is made to the embodiments of the method of the present application.
