Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 invention.
Due to imperfect Long Term Evolution (LTE) network deployment, LTE network signal strength in many places is weak. In these areas, when the user performs the voice service, the terminal cannot rely on the LTE network alone, and needs to perform circuit domain fallback by means of a third generation mobile communication or a second generation mobile communication (2G/3G) network, so as to implement the switching between the packet switched PS domain service and the circuit switched CS domain service, thereby ensuring the normal operation of the voice service.
A technology for switching from the PS domain service to the CS domain service is called Single Radio Voice Call Continuity (SRVCC) technology. The specific way to implement the handover may be to determine, for the network device, that the terminal needs to perform handover from the PS domain service to the CS domain service, and then establish a new bearer in the 2G/3G network to implement the handover. The process of establishing new bearer increases the switching duration and the continuity of voice service is poor.
In order to realize seamless switching between PS domain services and CS domain services, an Enhanced Single Radio Voice Call Continuity (eSRVCC) technology is introduced. In the eSRVCC technology, a device closer to a terminal than a network device, for example, an Access Transfer Gateway (ATGW) device, is added, and the PS domain service and the CS domain service are implemented by the device. In the eSRVCC technology, only a bearer needs to be established between the terminal and the ATGW device, and the transmission between the network device and the ATGW device is still performed through the original bearer. Compared with a scheme of establishing a new bearer between the network equipment and the terminal, the eSRVCC technology obviously reduces switching delay and enhances the continuity of voice service.
Since the eSRVCC function is provisioned for a cell, it is necessary to add an ATGW device, and it is therefore important to determine which target cells are provisioned with the eSRVCC function. In the prior art, for 2G/3G cells, a correlation factor for performing eSRVCC handover for each 2G/3G cell is extracted from multidimensional data suitable for eSRVCC handover, and a cell requiring eSRVCC function configuration is determined according to the correlation factor. In the prior art, the method for determining the target cell is complicated and has low efficiency.
In order to solve the problems in the prior art, the invention provides an eSRVCC function configuration method. The target cell to be configured with the eSRVCC function is determined by dividing the cell into grids and reporting a measurement report capable of reflecting the network signal strength by a terminal in the grids, so that the acquisition efficiency of the target cell can be improved. Fig. 1 is a schematic view of a scenario in which the eSRVCC function configuration method provided by the present invention is applicable. As shown in fig. 1, the applicable scenarios of the eSRVCC function configuration method provided by the present invention include: a network device and a plurality of terminals.
The network device is an access device that the terminal accesses to the mobile communication system in a wireless manner, and may be a network side in a base station NodeB, an evolved node b, a 5G mobile communication system or a new generation wireless (new radio, NR) communication system, a network side in a future mobile communication system, an access node in a WiFi system, and the like.

As shown in fig. 2, the eSRVCC function configuration method provided in this embodiment may include:
s201, determining a target cell according to a measurement report reported by a terminal in each grid and a corresponding relation between the grid and the cell, wherein the measurement report is used for indicating the signal strength of a Long Term Evolution (LTE) network and the signal strength of a first network, the first network is a third generation mobile communication 3G network or a second generation mobile communication 2G network, the LTE network signal strength of the target cell is smaller than a first strength threshold, and the first network signal strength is larger than a second strength threshold.
In this embodiment, the grid may be divided in the network coverage of the existing network device, that is, the grid may be divided according to the geographical location of the network coverage. The network coverage area of the network equipment comprises at least two cells. The coverage areas of the at least two cells include: a plurality of grids of the same size. The following embodiments describe a procedure for configuring an eSRVCC function for a cell in an area covered by a network thereof by using a network device. Fig. 3 is a schematic diagram of grid division in a network coverage cell of a network device. As shown in fig. 3, in this embodiment, taking the network coverage cell as a positive direction as an example, the grid may be, but is not limited to, a square, and the number of grids divided in each cell may be set in a self-defined manner in advance.
Optionally, the network device may send a measurement request to the terminal in the network coverage of the network device, where the measurement request is used to instruct the terminal to measure the long term evolution LTE network signal strength and the first network signal strength. The first network is a third generation mobile communication 3G network or a second generation mobile communication 2G network. It is understood that the long term evolution LTE network may also be replaced with a 5G mobile communication system network. After receiving the measurement request, the terminal measures the network signal strength and sends a measurement report containing the LTE network signal strength and the first network signal strength to the network equipment. The measurement report is used to indicate a long term evolution, LTE, network signal strength and a first network signal strength.
In this embodiment, since at least two cells covered by the network device are divided into a plurality of grids with the same size in advance, after receiving a measurement report sent by a terminal, the network device may determine the measurement report sent by the terminal in each grid. It will be appreciated that the identity of the terminal and the location of the terminal may be included in the measurement report.
After receiving the measurement report sent by the terminal, the network device may determine the measurement report sent by the terminal in each grid. The network device may determine the target cell according to the measurement report reported by the terminal located in each grid and the corresponding relationship between the grid and the cell. The LTE network signal intensity of the target cell is smaller than a first intensity threshold value, and the first network signal intensity is larger than a second intensity threshold value. I.e. the LTE network signal strength in the target cell is weak, but the first network signal strength is strong.
The network device in this embodiment may store a correspondence between a grid and a cell, where the correspondence is used to indicate a cell to which the grid belongs. Optionally, the network device may use, as the target cell, a cell corresponding to a grid where the LTE network signal strength is smaller than the first strength threshold and the first network signal strength is greater than the second strength threshold, according to the LTE network signal strength and the first network signal strength of the location where the terminal is located, which are fed back by the terminal in the measurement report.
Optionally, the network device may further obtain the number of terminals whose reported LTE network signal strength is smaller than the first strength threshold and whose first network signal strength is greater than the second strength threshold in each grid, and use the cell corresponding to the grid whose number is greater than the number threshold as the target cell.
S202, configuring an enhanced single radio voice call continuity eSRVCC function for the target cell.
After determining the target cell, the network device may configure an enhanced single radio voice call continuity (eSRVCC) function for the target cell.
In this embodiment, a possible implementation manner for configuring the eSRVCC function for the target cell by the network device is as follows: setting ATGW equipment for a target cell in advance, configuring configuration parameters connected with the ATGW equipment for the target cell by network equipment, configuring the configuration parameters connected with the ATGW equipment by the network equipment and the like. The specific configuration process may refer to a configuration process in the prior art, which is not described herein.
Another possible implementation is: the target cell is provided with a virtual switching device, which may function as the ATGW device in the prior art. The specific parameter configuration process may refer to the configuration process in the prior art.
In the eSRVCC function configuration method provided by the present invention, the coverage areas of at least two cells include: a plurality of grids of the same size, the method comprising: determining a target cell according to a measurement report reported by a terminal in each grid and the corresponding relation between the grid and the cell, wherein the measurement report is used for indicating the signal strength of a Long Term Evolution (LTE) network and the signal strength of a first network, the first network is a third generation mobile communication (3G) network or a second generation mobile communication (2G) network, the LTE network signal strength of the target cell is smaller than a first strength threshold value, and the first network signal strength is larger than a second strength threshold value; an enhanced single radio voice call continuity eSRVCC function is configured for the target cell. The invention improves the acquisition efficiency of the target cell and can more quickly configure the eSRVCC function for the target cell.
The eSRVCC function configuration method provided by the present invention is further described with reference to fig. 4. Fig. 4 is a second flowchart illustrating an eSRVCC function configuration method provided by the present invention. As shown in fig. 4, the eSRVCC function configuration method provided in this embodiment may include:
s401, obtaining the grids to which each terminal belongs according to the position of each terminal and the corresponding relation between the grids and the positions.
In this embodiment, the measurement report further includes: identification of the terminal. The network device may obtain the location of each terminal according to the identifier of each terminal.
Optionally, the network device may obtain the IP address of the terminal according to the identifier of the terminal, and further obtain the location of the terminal according to the IP address of the terminal. Optionally, if the terminal is a terminal with a positioning function, the terminal may be carried with its position in the measurement report.
When performing grid division on a cell covered by the network device, the network device may store each grid and a location corresponding to each grid, that is, a correspondence between grids and locations. After the network device obtains the position of each terminal, the network device may obtain the grid to which each terminal belongs according to the position of the terminal and the corresponding relationship between the grid and the position.
For example, the cell in fig. 3 is divided into 4 grids, grids 1, 2, 3 and 4, respectively. The network device receives the measurement reports sent by 3 terminals in grid 1 and receives the measurement reports sent by 4 terminals in grid 4.
S402, judging whether the number of the measurement reports reported by the terminals in each grid is greater than a number threshold value or not according to the measurement reports reported by the terminals in each grid; if so, S403 is executed, and if not, the process returns to S401.
After obtaining the grid to which each terminal belongs, the network device may determine the measurement report reported by the terminal in each grid. After determining the measurement reports reported by the terminals in each grid, the network device may count the number of the measurement reports reported by the terminals in the grid, and further determine whether the number of the measurement reports reported by the terminals in each grid is greater than a number threshold.
If the number of the measurement reports reported by the terminal in each grid is less than or equal to the number threshold, determining that the measurement reports in the grid cannot sufficiently reflect the coverage strength of the network signal of the grid, and determining to stop. And if the number of the measurement reports reported by the terminal in each grid is greater than the number threshold, determining that the measurement reports in the grid sufficiently reflect the coverage strength of the network signals of the grid, and determining the target cell according to the measurement reports reported by the terminals in the grid.
S403, obtain the maximum LTE network signal strength and the minimum first network signal strength in each grid.
In this embodiment, the measurement report reported by the terminal includes measurement results of the LTE network signal strength and the first network signal strength of the location where the terminal is located. After obtaining the measurement report reported by the terminal located in each grid, the network device may determine the maximum LTE network signal strength and the minimum first network signal strength in each grid according to the LTE network signal strength and the first network signal strength reported by each terminal. It can be understood that the maximum LTE network signal strength in each grid is the maximum LTE network signal strength reported by the terminal in the grid; the minimum first network signal strength in each grid is the minimum value of the first network signal strength reported by the terminal in the grid.
S404, determining a target cell according to the maximum LTE network signal intensity and the minimum first network signal intensity in each grid and the corresponding relation between the grids and the cells.
In this embodiment, because the LTE network signal strength and the strength of the first network signal strength in each grid are to be determined, a first threshold of the LTE network and a second threshold of the first network signal strength are stored in the network device in advance.
If the maximum LTE network signal strength in the first grid is smaller than the first threshold and the minimum first network signal strength is greater than the second threshold, it may be determined that the LTE network signal strength at the position corresponding to the first grid is weak and the first network signal strength is strong. Accordingly, the network device may determine the target cell according to a first grid and a corresponding relationship between the grid and the cell, where the first grid is one of the grids.
Optionally, the network device may use the cell corresponding to the first grid as the target cell according to the correspondence between the grids and the cells.
Optionally, the network device may further obtain the number of terminals with LTE network signal strength less than the first threshold and the first network signal strength greater than the second threshold, which are reported in each grid. And if the number of the terminals is larger than the preset number, determining the cell corresponding to the first grid as a target cell. Alternatively, the preset number may be smaller than the number threshold.
Optionally, if the minimum LTE network signal strength in the second grid is greater than the first threshold and the minimum first network signal strength is greater than the second threshold, it is determined that both the LTE network signal strength and the first network signal strength in the second grid are strong, and it is determined that the eSRVCC function does not need to be configured for the cell corresponding to the second grid.
Optionally, if the minimum LTE network signal strength in the second grid is greater than the first threshold and the minimum first network signal strength is less than the second threshold, it is determined that the LTE network signal strength in the second grid is strong, but the first network signal strength is weak, and it is determined that the eSRVCC function does not need to be configured for the cell corresponding to the second grid.
Optionally, if the maximum LTE network signal strength in the second grid is smaller than the first threshold and the minimum first network signal strength is smaller than the second threshold, it is determined that both the LTE network signal strength and the first network signal strength in the second grid are weak, and it is determined that the cell corresponding to the second grid is the cell capable of configuring the eSRVCC function. Optionally, after configuring the eSRVCC function for the target cell, the eSRVCC function may be configured for the cell corresponding to the second grid.
Optionally, after the network device obtains the first grid according to the measurement report reported by the terminal located in each grid, the boundary between the first grid and another grid may be used as the service boundary of the packet switched PS domain service and the circuit switched CS domain service.
If the eSRVCC function is configured for each cell corresponding to the first grid, a large configuration cost may be required. In this embodiment, the network device may obtain the areas of at least two first grids adjacent to each other according to the position of each first grid. I.e. the areas of at least two first grids located adjacent to each other are summed.
And if the areas of the at least two first grids adjacent to the position are smaller than or equal to the area threshold value, determining that the eSRVCC function is not configured for the cells corresponding to the at least two first grids adjacent to the position. If the areas of the at least two first grids adjacent to the position are larger than the area threshold, obtaining the cells corresponding to the at least two first grids adjacent to the position according to the corresponding relation between the grids and the cells, and taking the cells corresponding to the at least two first grids adjacent to the position as target cells.
S405, configuring an enhanced single radio voice call continuity eSRVCC function for the target cell.
The implementation in S405 in this embodiment may refer to the related description in S201 in the foregoing embodiment, and is not described herein again.
In this embodiment, a measurement report reported by a terminal in each grid is obtained, and a target cell is determined according to the maximum LTE network signal strength and the minimum first network signal strength in each grid. Specifically, if the maximum LTE network signal strength in the first grid is smaller than the first threshold and the minimum first network signal strength is greater than the second threshold, the boundary between the first grid and another grid may be used as the service boundary between the PS domain service and the CS domain service, and the cell corresponding to the first grid may be used as the target cell, so as to improve the acquisition efficiency of the target cell. Further, in the present embodiment, the areas of at least two first grids adjacent to each other in position are acquired. If the area is larger than the area threshold, the cells corresponding to at least two first grids adjacent to each other in position are used as target cells according to the corresponding relation between the grids and the cells, and the eSRVCC function is configured for the target cells, so that the configuration cost of the eSRVCC function is reduced.
