Description

A network redirection method, apparatus, and storage medium Technical Field

[0001] This application relates to the field of communications, and more particularly to a network redirection method, apparatus, and storage medium. Background Technology

[0002] Fifth-generation mobile communication technology (5G) is a new generation of broadband mobile communication technology characterized by high speed, low latency, and massive connectivity. Currently, operators' 5G networks are largely operational, covering many areas. However, some areas are covered by both 5G and 4G networks. In these areas, if terminal devices capable of using 5G networks are using 4G networks, they will generate excessive data traffic, resulting in a poor user experience and hindering the improvement of 5G network performance. Therefore, we urgently need to propose a network redirection method. Summary of the Invention

[0003] This application provides a network redirection method, apparatus, and storage medium. These can improve user experience and network performance.

[0004] To achieve the above technical objectives, this application adopts the following technical solution:

[0005] In a first aspect, embodiments of this application provide a network redirection method applied to a base station. The method includes: detecting a first network capability of a target terminal; the target terminal is any terminal using a second network of a second cell managed by the base station; the second cell is a cell managed by the base station that supports the second network; when the target terminal has the first network capability, sending first indication information to the target terminal; wherein the first indication information is used to instruct the target terminal to start detecting the signal strength of the first network of the first cell; if the detected signal strength of the first network of the first cell is greater than or equal to a strength threshold, the target terminal redirects from the second network to the first network; the coverage areas of the first cell and the second cell overlap, and the target terminal is within the overlapping coverage area of ​​the first cell and the second cell; the first cell is a cell managed by the base station that supports the first network; the first network and the second network are cellular networks of different standards, and the communication capability of the first network is higher than that of the second network; the second cell is a cell managed by the base station that supports the second network; if the target terminal does not redirect from the second network to the first network, then calculating the cumulative traffic of the target terminal; when the cumulative traffic of the target terminal is greater than or equal to a first preset traffic threshold, sending a control command to the target terminal; wherein the control command is used to control the target terminal to blindly redirect from the second network to the first network.

[0006] Understandably, when the target terminal does not redirect from the second network to the first network and generates a large amount of traffic on the second network, it will increase the user's service usage costs and reduce the user's service experience. Therefore, the base station can force the target terminal to blindly redirect to the first network to improve the user's service experience and at the same time improve the performance of the first network.

[0007] In one possible implementation, the target terminal having a first network capability includes: the target terminal supporting a first network, and the first network of the target terminal being turned on.

[0008] In another possible implementation, the first indication information includes the frequency of the first cell and the PCI of the first cell; the frequency of the first cell is used to indicate the frequency to be used by the target terminal when initiating detection of the first cell; the PCI of the first cell is used to indicate the identifier of the network signal to be used by the target terminal when redirecting from the second network to the first network.

[0009] It is understandable that the frequency and PCI of the first cell are important information for the target terminal to detect the first cell and use the first network of the first cell. The first indication information contains the above information, which helps the target terminal to detect the network signal of the first cell.

[0010] In another possible implementation, the control command includes the frequency point of the first cell and the PCI of the first cell; the frequency point of the first cell is used to indicate the frequency to be used by the target terminal when initiating detection of the first cell; the PCI of the first cell is used to indicate the identifier of the network signal to be used by the target terminal when redirecting from the second network to the first network.

[0011] It is understandable that the frequency and PCI of the first cell are important information for the target terminal to detect the first cell and use the first network of the first cell. The control command contains the above information, which helps to force the target terminal to redirect from the second network to the first network.

[0012] In another possible implementation, after calculating the cumulative traffic of the target terminal if the target terminal is not redirected from the second network to the first network, and before the cumulative traffic of the target terminal is greater than or equal to a first preset traffic threshold, the method further includes: sending second indication information to the target terminal when the cumulative traffic of the target terminal is greater than or equal to a second preset traffic threshold; wherein the second indication information includes a target detection frequency; the second indication information is used to instruct the target terminal to use the target detection frequency to detect the first cell; and the second preset traffic threshold is less than the first preset traffic threshold.

[0013] Understandably, the target terminal typically has a pre-configured frequency for transmitting scanning signals, and the target detection frequency is higher than this pre-configured frequency. Therefore, by using this target detection frequency to transmit scanning signals, the target terminal can accelerate the detection of the first cell, causing it to redirect from the second network to the first network.

[0014] In another possible implementation, the target detection frequency is the fastest first cell detection frequency configured in the base station.

[0015] Understandably, the target terminal uses the fastest first cell detection frequency, which can achieve the fastest first cell detection speed within the configuration range, thus speeding up the redirection to the first network.

[0016] In another possible implementation, the first cell includes a 5G cell, the second cell includes a 4G cell, the first network includes a 5G network, the second network includes a 4G network, and the first network capability includes 5G network capability.

[0017] It is understood that the above are specific application scenarios for the first and second communities. This application uses the above examples for illustration, but is not actually limited to these.

[0018] Secondly, embodiments of this application provide a network redirection device, wherein the network redirection device is applied to various modules of the network redirection method in the first aspect or any possible implementation of the first aspect.

[0019] Thirdly, embodiments of this application provide a network redirection apparatus, including a memory and a processor. The memory and the processor are coupled; the memory stores computer program code, which includes computer instructions. When the processor executes the computer instructions, the network redirection apparatus performs a network redirection method as described in the first aspect and any possible implementation thereof.

[0020] Fourthly, this application provides a computer-readable storage medium including computer instructions. When the computer instructions are executed on a network redirection device, the network redirection device causes the network redirection device to perform a network redirection method as described in the first aspect and any possible implementation thereof.

[0021] Fifthly, this application provides a computer program product comprising computer instructions. When the computer instructions are executed on a network redirection device, the network redirection device causes the network redirection device to perform a network redirection method as described in the first aspect and any possible implementation thereof.

[0029] For ease of understanding, the relevant terms used in the embodiments of this application will be briefly introduced below:

[0030] (1) A cell, also known as a cellular cell, refers to the area covered by the signal of a base station or part of a base station (fan antenna) in a cellular mobile communication system, within which a mobile station can reliably communicate with the base station via a wireless channel.

[0031] (2) Physical Cell Identifier (PCI): Firstly, it is used to identify cells during cell search, facilitating the terminal's differentiation of wireless network signals from different cells. Multiple cells received by the terminal must not have the same PCI, otherwise interference will occur. Secondly, it is used for mobility management, assisting in measuring and reporting sector signal strength during handover or cell reselection while the terminal is moving.

[0032] (3) Redirection: This means redirecting various network requests to other locations using various methods.

[0033] Hereinafter, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," or "third," etc., may explicitly or implicitly include one or more of that feature.

[0034] As described in the background technology, in some areas that are simultaneously covered by 5G and 4G networks, if a terminal with 5G network capability uses a 4G network, it will generate a large amount of 4G traffic, resulting in a poor user experience and hindering the improvement of 5G network performance.

[0035] Based on this, this application proposes a network redirection method applied to a base station. In this method, the base station redirects a target terminal with a first network capability (e.g., 5G network capability) from a second network (e.g., a 4G network) to a first network (e.g., a 5G network). Specifically, firstly, the base station detects the first network capability of the target terminal. If the target terminal has the first network capability, it instructs the target terminal to be redirected from the second network to the first network. Secondly, if the target terminal is not redirected to the first network, and the cumulative traffic used on the second network exceeds a first preset traffic threshold, the base station controls the target terminal to blindly redirect from the second network to the first network. It is understood that in this method, when the target terminal is not redirected from the second network to the first network, and the target terminal generates a large amount of traffic on the second network, this will increase the user's service usage cost and reduce the user's service experience. Therefore, the base station can forcibly control the target terminal to blindly redirect to the first network to improve the user's service experience and simultaneously improve the performance of the first network.

[0036] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0037] Please refer to Figure 1, which shows a schematic diagram of an implementation environment involved in the network redirection method provided in this application embodiment. As shown in Figure 1, the implementation environment may include: base station 110 and terminal 120.

[0038] Base station 110, or public mobile communication base station, is an interface device for mobile devices to access the Internet and is also a type of radio station. The main function of a base station is to provide wireless coverage, that is, to enable wireless signal transmission between wired communication networks and wireless terminals. In this embodiment, the cells managed by base station 110 include, but are not limited to, a first cell and / or a second cell, such as a 4G cell and / or a 5G cell. A 4G cell refers to an area covered by a 4G network, and a 5G cell refers to an area covered by a 5G network.

[0039] Terminal 120 is a type of mobile smart terminal device that has the ability to access the Internet and typically runs on various operating systems.

[0040] For example, terminal 120 includes: mobile phone, tablet computer, in-vehicle smart terminal, smart TV or wearable device, etc.

[0041] Optionally, the terminal 120 has a switch for a first network (e.g., a 5G network). This switch can be a software switch or a hardware switch, and this embodiment of the application does not limit this. If the first network switch of the terminal 120 is turned on, and the terminal 120 supports the first network, then the terminal 120 has the first network capability.

[0042] In this embodiment, terminal 120 wirelessly accesses base station 110 and uses the second network of the second cell managed by base station 110 (e.g., the 4G network of a 4G cell). When base station 110 detects that terminal 120 (i.e., the target terminal) with first network capability is using the second network of the second cell and the accumulated traffic reaches a certain traffic threshold (e.g., a first preset traffic threshold), it controls terminal 120 to be redirected to the first network (e.g., a 5G network) in a blind redirection manner.

[0043] This implementation environment may include one base station 110 for managing a first cell and a second cell. Alternatively, the implementation environment may include at least two base stations 110, respectively for managing a first cell and a second cell, with the coverage area of ​​the second cell overlapping with that of the first cell. In this embodiment, the implementing entity is the base station 110 managing the second cell, and this embodiment does not limit whether the first cell and the second cell are managed by the same base station.

[0044] The network redirection method provided in the embodiments of this application will be described below:

[0045] The network redirection method provided in this application embodiment can be applied to base station 110. The executing entity of the network redirection method provided in this application embodiment can also be a network redirection device. This network redirection device can be a base station, or a central processing unit (CPU) in the base station, or a control module in the base station for executing the network redirection method. The following description uses the method provided in this application embodiment as an example of a base station.

[0046] Please refer to Figure 2, which is a flowchart of a network redirection method provided in an embodiment of this application. As shown in Figure 2, the method may include S101-S109.

[0047] S101: The base station's primary network capability for detecting target terminals.

[0048] The target terminal is any one of the multiple terminals in the second network of the second cell managed by the base station.

[0049] The second cell is a cell managed by the base station that supports a second network. For example, the second cell includes, but is not limited to, a 4G cell, and the second network includes, but is not limited to, a 4G network. The second network is the network signal in the area covered by the second cell.

[0050] In one example, multiple terminals use the second network of the second cell managed by the base station, and the base station selects any one of the terminals to detect the terminal's first network capability.

[0051] Specifically, the base station detects the target terminal's first network capability, including: whether the base station detects whether the target terminal supports the first network, and whether the target terminal's first network switch is in the on state.

[0052] The above support for the first network can be understood as the ability to use the first network for communication or networking.

[0053] The aforementioned "switch for the first network" refers to the switch that turns the use of the first network on or off. The target terminal can only access the first network when this switch is on.

[0054] In one possible implementation, the base station sends a detection signal to the target terminal to detect the target terminal's first network capability. Correspondingly, if the target terminal possesses the first network capability, it returns response information indicating that it has the first network capability to the base station.

[0055] In one example, the first network capability includes, but is not limited to, 5G network capability. The base station sends a detection signal to the target terminal to detect the target terminal's first network capability. If the target terminal supports 5G network and the 5G switch on the target terminal is turned on, then the target terminal has the first network capability, and at this time, the target terminal returns response information to the base station indicating that it has the first network capability.

[0056] S102: When the target terminal has the first network capability, the base station sends the first indication information to the target terminal.

[0057] The first indication information is used to instruct the target terminal to start detecting the signal strength of the first network of the first cell. If the detected signal strength of the first network is greater than or equal to the strength threshold, the target terminal is redirected from the second network to the first network. The coverage areas of the first cell and the second cell overlap, and the target terminal is located within the overlapping coverage area of ​​the first cell and the second cell.

[0058] The aforementioned first cell can be a cell managed by the base station that supports the first network. For example, the first cell includes, but is not limited to, a 5G cell, and the first network includes, but is not limited to, a 5G network. The first network is the network signal in the area covered by the first cell.

[0059] The first network and the second network mentioned above are cellular networks of different standards, with the first network having a higher communication capability than the second network. Therefore, the first network and the second network can be 5G and 4G networks, or 4G and 3G networks, or 6G and 4G networks, or 6G and 5G networks, etc. Specifically, this application does not limit the specific types of the first and second networks, as long as the first network has a higher communication capability than the second network.

[0060] In the first cell and the second cell mentioned above, for a target terminal with the first network capability, the first cell has a higher priority than the second cell. That is, the target terminal connects to the first network of the first cell with priority over the second network of the second cell.

[0061] In one example, the event indicated by the first indication information is event B1. Event B1 means that the signal strength of the inter-system neighboring cell is stronger than an absolute threshold. The inter-system neighboring cell can be understood as the first cell in this application embodiment, and the signal strength being stronger than an absolute threshold can be understood as the signal strength of the first network in this application embodiment being greater than or equal to the strength threshold.

[0062] In one example, as shown in Figure 3, which illustrates a first cell and a second cell managed by a base station, the target terminal is located within the overlapping coverage area of ​​the first and second cells.

[0063] The first indication information includes the frequency of the first cell and the physical identifier (PCI) of the first cell.

[0064] The frequency of the first cell is used to indicate the frequency that the target terminal will use when it starts detecting the first cell; the PCI of the first cell is used to indicate the network signal identifier that the target terminal will use when redirecting from the second network to the first network.

[0065] A frequency point refers to an absolute frequency value. It is generally the center frequency of the modulated signal. A frequency point is a number assigned to a fixed frequency. The frequency point of the first cell indicates the frequency of the first cell.

[0066] The information included in the first instruction information helps the target terminal detect the network signal of the first cell.

[0067] The specific method for the target terminal to initiate the detection of the first cell may include: the target terminal adjusts the frequency of the scanning signal to the frequency indicated by the frequency of the first cell based on the frequency point of the first cell contained in the received first indication information, and transmits the scanning signal outward to detect the first network signal strength of the first cell.

[0068] When the target terminal detects the first network signal of the first cell, and the strength of the network signal is greater than the strength threshold, the target terminal actively redirects from the second network to the first network.

[0069] The first network and the second network are two wireless networks with different frequencies and frequency bands. The target terminal is redirected from the second network to the first network, that is, the target terminal is redirected from communicating with the base station using the frequency and frequency band of the first network to communicating with the base station using the frequency and frequency band of the second network.

[0070] A target terminal with first network capability can use either the first network or the second network. However, using the first network provides a better user experience and improves the performance of the first network. Therefore, the base station instructs the target terminal to redirect from the second network to the first network to enhance the user experience and improve the performance of the first network.

[0071] S103: The target terminal starts detecting the first cell.

[0072] The target terminal transmits a scanning signal at the same frequency as the first cell according to a pre-configured frequency in order to detect the first cell.

[0073] If the target terminal detects that the signal strength of the first network in the first cell is greater than the strength threshold, the target terminal will be redirected from the second network to the first network.

[0074] If the target terminal does not detect that the signal strength of the first network in the first cell is greater than the strength threshold, the target terminal will continue to detect the first cell.

[0075] S104: If the target terminal is not redirected from the second network to the first network, the base station will count the cumulative traffic of the target terminal.

[0076] One possible way for a base station to determine that a target terminal has not been redirected from the second network to the first network is that the base station detects that the target terminal is continuously using the second network, or in other words, the target terminal is continuously generating traffic using the second network.

[0077] In the above possible implementations, since the target terminal is using the second network, it will generate traffic while using the second network. If the target terminal is redirected from the second network to the first network, it will no longer generate traffic on the second network. Therefore, if the target terminal continues to generate traffic on the second network, it can be determined that the target terminal has not been redirected from the second network to the first network.

[0078] The cumulative traffic of the target terminal is the total traffic generated on the second network from the time the target terminal last connected to the base station until the base station starts counting the traffic.

[0079] In one example, the second network is a 4G network. The target terminal accesses the 4G network at 12:00. The base station counts the cumulative traffic of the target terminal at 12:10. The cumulative traffic is the total traffic generated by the target terminal from 12:00 to 12:10.

[0080] S105 (optional): When the traffic of the target terminal is greater than or equal to the second preset traffic threshold, the base station sends the second indication information to the target terminal.

[0081] The second indication information includes the target detection frequency; the second indication information is used to instruct the target terminal to use the target detection frequency to detect the first cell; the target detection frequency is the fastest first cell detection frequency configured in the base station.

[0082] The second preset traffic threshold is a traffic threshold preset in the base station, for example: 20Mbyte.

[0083] The frequency of the cell included in the first indication information indicates the frequency of the scanning signal, while the target detection frequency included in the second indication information indicates the frequency at which the target terminal transmits the scanning signal.

[0084] Generally, the target terminal has a pre-configured frequency for transmitting scanning signals. The target detection frequency is higher than the pre-configured frequency for transmitting scanning signals in the target terminal. For example, if the target detection frequency mentioned above is the fastest first cell detection frequency configured in the base station, then the target terminal can use this target detection frequency to transmit scanning signals, which can speed up the detection of the first cell and cause the target terminal to redirect from the second network to the first network.

[0085] S106: The target terminal uses the target detection frequency to detect the first cell.

[0086] Specifically, the target terminal transmits a scanning signal at the same frequency as the first cell according to the target detection frequency in order to detect the first cell.

[0087] If the target terminal detects that the signal strength of the first network in the first cell is greater than or equal to the strength threshold, the target terminal will be redirected from the second network to the first network.

[0088] If the target terminal does not detect a signal strength of the first network of the first cell that is greater than or equal to the strength threshold, the target terminal continues to use the target detection frequency to detect the first cell.

[0089] S107: If the target terminal is not redirected from the second network to the first network, the base station will count the cumulative traffic of the target terminal.

[0090] For a detailed description of S107, please refer to S104.

[0091] In fact, the base station counts the cumulative traffic of the target terminal in real time, for example, once every 10 seconds. Each count is calculated from the last time the target terminal connected to the base station. This method allows the base station to detect the cumulative traffic generated by the target terminal in real time.

[0092] S108: When the traffic of the target terminal is greater than or equal to the first preset traffic threshold, a control command is sent to the target terminal.

[0093] Among them, the control command is used to control the target terminal to blindly redirect from the second network to the first network.

[0094] The control command includes the frequency and PCI of the first cell. The frequency and PCI of the first cell are important information for the target terminal to detect the first cell and use the first network of the first cell. The control command includes the above information, which helps to force the target terminal to blindly redirect from the second network to the first network.

[0095] The first preset traffic threshold is a traffic threshold preset in the base station, for example, 50 Mbytes. The first preset traffic threshold is greater than the second preset traffic threshold.

[0096] Blind redirection occurs when, after the base station sends the frequency of the first cell to the target terminal, the target terminal does not need to measure the signal strength of the first network of the first cell at that frequency. Instead, it blindly redirects to the first network of the first cell under the control of the control command.

[0097] The first indication information in S102 is a measurement-based redirection. This redirection method measures the cell at the redirected frequency point and only performs a handover after a trigger event (e.g., event B1, i.e., the signal strength of the first network in the first cell detected in S102 is greater than or equal to the strength threshold). In contrast, in S106, the base station controls the target terminal to blindly redirect from the second network to the first network. Therefore, the blind redirection to the first network in S106 does not require measurement-based forceful network redirection of the target terminal.

[0098] Understandably, since the cumulative traffic generated by the target terminal in the second network is greater than or equal to the first preset traffic threshold, in order to prevent the target terminal from continuing to generate a large amount of traffic, the base station forcibly controls the target terminal to be redirected from the second network to the first network, so that the users of the target terminal can have a better service experience, while improving the efficiency of the first network.

[0099] S109: Under the control of the control command, the target terminal blindly redirects from the second network to the first network.

[0100] In a network redirection method proposed in this application, the base station redirects a target terminal with first network capabilities from a second network to the first network. It is understood that in this method, when the target terminal generates a large amount of traffic on the second network, the user's service usage cost will increase, and the user's service experience will decrease. Therefore, the base station can forcibly control the target terminal to be redirected to the first network in a blind redirection manner to improve the user's service experience and simultaneously improve the performance of the first network.

[0101] The foregoing primarily describes the solutions provided by the embodiments of this application from a methodological perspective. To achieve the aforementioned functions, it includes corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, in conjunction with the units and algorithm steps of the various examples described in the embodiments disclosed herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution.
