Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a carrier configuration method, a server, and a storage medium. Background Art

[0002] In the 5G (5th Generation) network architecture, 5G gNB (gNodeB, 5G base station) and 4G eNB (evolvedNodeB, 4G base station) are dual-connected in NSA (Non-standalone), among which the number of carrier parameters supported by 5G gNB can reach up to 16.

[0003] However, when NSA does not support direct wireless signaling between 5G gNB and UE (User Equipment), 4G eNB is responsible for signaling transmission between UE and 5G gNB through X2 interface. Since 5G gNB supports up to 16 carrier parameters, that is, RRC Reconfiguration (Radio Resource Control Reconfiguration) message can contain up to 16 carrier parameters, the length of RRC Reconfiguration message is very long. However, 4G eNB, as the previous generation of wireless base station, may not be able to support the processing of longer RRC Reconfiguration messages due to model, hardware system limitations and software system limitations, which may cause the failure of carrier parameter transmission. Summary of the invention

[0004] The main purpose of the embodiments of the present application is to propose a carrier configuration method, a server and a storage medium, which can avoid the problem that the 4G base station cannot transmit carrier parameters as much as possible, thereby realizing the configuration of carrier parameters.

[0005] To achieve the above-mentioned purpose, an embodiment of the present application provides a carrier configuration method, which is applied to a 5G base station, and the method includes: obtaining the number N1 of carrier parameters supported by the 4G base station; performing a configuration step, and the configuration step includes: sending several auxiliary carrier parameters of the M auxiliary carrier parameters supported by the 5G base station to the terminal through the 4G base station; wherein the number of the several auxiliary carrier parameters is not greater than N1, the configuration step is performed K times, and N1, M, and K are all integers greater than or equal to 1.

[0006] To achieve the above object, an embodiment of the present application provides a carrier configuration method, which is applied to a 4G base station. The method includes: receiving a base station handover request sent by a first 5G base station, where the base station handover request includes the number N1 of carrier parameters supported by the 4G base station; where N1 is an integer greater than or equal to 1, and the base station handover request further indicates a handover from the first 5G base station to a second 5G base station; sending a base station connection request including the number N1 of carrier parameters supported by the 4G base station to the second 5G base station; receiving a configuration request including P carrier parameters sent by the second 5G base station, and sending some of the P carrier parameters to the terminal; where at least the secondary carrier parameters are included in the P carrier parameters, P is not greater than N1, and N1 and P are integers greater than or equal to 1.

[0007] To achieve the above object, an embodiment of the present application provides a carrier configuration method, which is applied to a first 4G base station. The method includes: sending a base station connection request including the number N2 of carrier parameters supported by the first 4G base station to a second 5G base station through a second 4G base station; receiving a configuration request including L carrier parameters sent by the second 5G base station through the second 4G base station, and sending some of the L carrier parameters to the terminal; where at least the secondary carrier parameters are included in the L carrier parameters, L is not greater than N2, and L is an integer greater than or equal to 1.

[0008] To achieve the above object, an embodiment of the present application further provides a server, including: at least one processor; and a memory communicatively connected to the at least one processor; where the memory stores instructions executable by the at least one processor, and when the instructions are executed by the at least one processor, the at least one processor is enabled to execute the above-mentioned carrier configuration method.

[0009] To achieve the above object, an embodiment of the present application further provides a computer-readable storage medium, storing a computer program, where when the computer program is executed by a processor, the above-mentioned carrier configuration method is implemented.

[0010] For the carrier configuration method, server, and storage medium proposed in the present application, the 5G base station obtains the number N1 of carrier parameters supported by the 4G base station; performs a configuration step, where the configuration step includes: sending some of the M secondary carrier parameters supported by the 5G base station to the terminal through the 4G base station; where the number of the some secondary carrier parameters is not greater than N1, and the configuration step is executed K times, and N1, M, and K are all integers greater than or equal to 1. Since the number of the some secondary carrier parameters is not greater than the number N1 of carrier parameters supported by the 4G base station, it is possible to avoid the problem that the 4G base station cannot transmit carrier parameters as much as possible, thereby realizing the configuration of carrier parameters.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will elaborate on each embodiment of the present application in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present application, many technical details are presented for the purpose of enabling readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented. The following division of each embodiment is for convenience of description and should not constitute any limitation to the specific implementation manner of the present application. Each embodiment can be combined and cross-referenced with each other on the premise of not being contradictory.

[0018] The first embodiment of the present invention relates to a carrier configuration method applied to a 5G base station. The specific process is as Figure 1 shown and includes:

[0019] Step 101: Obtain the number N1 of carrier parameters supported by the 4G base station.

[0020] Specifically, when a terminal needs to use the carrier parameters of a 5G base station for data transmission, the terminal needs to first configure the carrier parameters supported by the 5G base station locally. Since the 5G base station needs to communicate with the terminal through the 4G base station, during the process of the 5G base station sending the carrier parameters to the terminal, the number of secondary carrier parameters sent is limited by the number of carrier parameters supported by the 4G base station. Therefore, the 5G base station needs to first obtain the number N1 of carrier parameters supported by the 4G base station.

[0021] In one example, the specific flowchart for obtaining the number N1 of carrier parameters supported by a 4G base station is as follows Figure 2 shown and includes:

[0022] Step 1011: Receive a base station connection request sent by the 4G base station.

[0023] Step 1012: Obtain the number N1 of carrier parameters supported by the 4G base station from the base station connection request.

[0024] Specifically, during the movement of the terminal, the signal between the terminal and other 5G base stations may become weak, while the signal between the terminal and the current 5G base station may become strong. At this time, other 5G base stations can sense the change in signal strength through the terminal measurement report, so as to know that a handover to the current 5G base station is required. Both other 5G base stations and the current 5G base station communicate with the terminal through the current 4G base station. First, other 5G base stations send a base station handover request containing the number N1 of carrier parameters supported by the 4G base station to the 4G base station. N1 is an integer greater than or equal to 1, and the base station handover request also indicates a handover from other 5G base stations to the current 5G base station. Therefore, after receiving the base station handover request, the 4G base station sends a base station connection request containing the number N1 of carrier parameters supported by the 4G base station to the current 5G base station, and the current 5G base station receives the base station connection request containing the number N1 of carrier parameters supported by the 4G base station sent by the 4G base station. The 5G base station can then parse the base station connection request to obtain the number N1 of carrier parameters supported by the 4G base station.

[0025] Through such a method, the number N1 of carrier parameters supported by the 4G base station can be directly obtained from the 4G base station, and the number of carrier parameters supported by the 4G base station can be obtained relatively quickly.

[0026] In one example, the specific flowchart for obtaining the number N1 of carrier parameters supported by a 4G base station is as follows Figure 3 shown and includes:

[0027] Step 1013: Send a configuration request containing Z secondary carrier parameters to the 4G base station; where the Z secondary carrier parameters are read from M secondary carrier parameters, and Z is an integer greater than or equal to 1.

[0028] Specifically, the 5G base station reads Z secondary carrier parameters from the supported M secondary carrier parameters and sends a configuration request containing the Z secondary carrier parameters to the 4G base station, where Z is an integer greater than or equal to 1. In one example, the value of Z for the first time is M, that is, the 5G base station sends a configuration request containing M secondary carrier parameters to the 4G base station. Through such a method, if the number of carrier parameters supported by the 4G base station is M, since it starts from the largest number M, the number M of carrier parameters supported by the 4G base station can be obtained more accurately.

[0029] Step 1014, determine whether a response from the 4G base station is received within a preset duration. If yes, proceed to Step 1015; if no, proceed to Step 1017.

[0030] Step 1015, determine whether the response from the 4G base station is a message indicating successful processing of the configuration request. If yes, proceed to Step 1018; if no, proceed to Step 1016.

[0031] Step 1016, determine whether the message indicating failed processing of the configuration request in the response from the 4G base station contains the number of carrier parameters supported by the 4G base station. If yes, proceed to Step 1018; if no, proceed to Step 1017.

[0032] Step 1017, set the value of Z in this instance to be less than the value of Z in the previous instance.

[0033] Step 1018, obtain the number N1 of carrier parameters supported by the 4G base station.

[0034] Step 1019, set the number N1 of carrier parameters supported by the 4G base station as the value of Z in this instance.

[0035] Specifically, after the 4G base station receives a configuration request containing Z secondary carrier parameters, if the number of carrier parameters supported by the 4G base station is less than Z, the 4G base station cannot process the configuration request and thus cannot send the configuration request to the terminal. At this time, the 4G base station may not respond to the 5G base station or may respond to the 5G base station with a message indicating failed processing of the configuration request. The 5G base station can set the preset duration according to actual needs. If the 5G base station does not receive a response from the 4G base station within the preset duration or receives a message indicating failed processing of the configuration request from the 4G base station, it sets the value of Z in this instance to be less than the value of Z in the previous instance and re-enters Step 1013.

[0036] If the 5G base station receives a response within the preset duration and the response is a message indicating failed processing of the configuration request, the 5G base station parses the message indicating failed processing of the configuration request. If the message indicating failed processing of the configuration request contains the number N1 of carrier parameters supported by the 4G base station, it directly obtains the number N1 of carrier parameters supported by the 4G base station; if the message indicating failed processing of the configuration request does not contain the number of carrier parameters supported by the 4G base station, it sets the value of Z in this instance to be less than the value of Z in the previous instance and re-enters Step 1013.

[0037] In one example, the value of Z in this instance is the value of Z in the previous instance minus 1. By taking values for Z in this way successively, the adjustment step size of the value of Z is small, and the number of carrier parameters supported by the 4G base station can be obtained more accurately.

[0038] In one example, the value of Z this time is the integer obtained by dividing the value of Z last time by n, where n is an integer greater than or equal to 2. By this method, the number of carrier parameters supported by the 4G base station can be obtained relatively quickly.

[0039] In one example, after the 4G base station receives a configuration request containing Z secondary carrier parameters, if the number of carrier parameters supported by the 4G base station is greater than or equal to Z, the 4G base station can process the configuration request. The 4G base station sends the configuration request containing Z secondary carrier parameters to the terminal and responds with a message indicating successful processing of the configuration request to the 5G base station. The 5G base station receives the message indicating successful processing of the configuration request responded by the 4G base station within a preset time duration and obtains that the number N1 of carrier parameters supported by the 4G base station is Z this time.

[0040] In one example, the message indicating successful processing of the configuration request is the configuration success message of the Z secondary carrier parameters responded by the 4G base station. After the 4G base station receives a configuration request containing Z secondary carrier parameters, if the number of carrier parameters supported by the 4G base station is greater than or equal to Z, the 4G base station can process the configuration request. The 4G base station sends the configuration request containing Z secondary carrier parameters to the terminal. After receiving the configuration request, the terminal configures the Z secondary carrier parameters and responds with a configuration success message of the Z secondary carrier parameters to the 4G base station. The 4G base station sends the responded configuration success message of the Z secondary carrier parameters to the 5G base station. The 5G base station receives the configuration success message of the Z secondary carrier parameters responded by the 4G base station within a preset time duration and obtains that the number N1 of carrier parameters supported by the 4G base station is Z this time.

[0041] By this method, through the interaction of multiple messages, the number of carrier parameters supported by the 4G base station can be accurately obtained.

[0042] In one example, obtaining the number N1 of carrier parameters supported by the 4G base station includes: The 5G base station locally stores the identifiers of multiple 4G base stations. Since the 5G base station knows which 4G base station it is connected to, the 5G base station can obtain the identifier of the 4G base station from local storage. According to the identifier, query the corresponding relationship between the identifier stored locally in the 5G base station and the number of carrier parameters. If the number of carrier parameters corresponding to the identifier of the 4G base station is queried, obtain the number N1 of carrier parameters supported by the 4G base station; if the number of carrier parameters corresponding to the identifier of the 4G base station is not queried, the 5G base station uses the interaction of multiple messages to obtain the number of carrier parameters supported by the 4G base station.

[0043] In one example, obtaining the number N1 of carrier parameters supported by a 4G base station includes: The 5G base station locally stores the identifiers of multiple 4G base stations. Since the 5G base station knows which 4G base station is connected to itself, the 5G base station can obtain the identifier of the 4G base station locally. The 5G base station sends a request message containing the 4G base station identifier to an external network management device. The external network management device queries the correspondence between the identifiers stored locally in the external network management device and the number of carrier parameters. If the number of carrier parameters corresponding to the identifier of the 4G base station is queried, the number N1 of carrier parameters supported by the 4G base station is obtained, and a message containing the number N1 of carrier parameters supported by the 4G base station is sent to the 5G base station, so that the 5G base station obtains the number N1 of carrier parameters supported by the 4G base station; if the number of carrier parameters corresponding to the identifier of the 4G base station is not queried, the external network management device responds with a message indicating a query failure to the 5G base station, and the 5G base station then obtains the number of carrier parameters supported by the 4G base station through the interaction of multiple messages. Among them, the correspondence between the identifiers stored locally in the external network management device and the number of carrier parameters is set manually in advance. Through such a method, the number N1 of carrier parameters supported by the 4G base station can be obtained relatively quickly.

[0044] Step 102, perform a configuration step, where the configuration step includes: sending a plurality of secondary carrier parameters among the M secondary carrier parameters supported by the 5G base station to the terminal through the 4G base station; where the number of the plurality of secondary carrier parameters is not greater than N1, and the configuration step is performed K times, and N1, M, and K are all integers greater than or equal to 1.

[0045] Specifically, the 5G base station reads a plurality of secondary carrier parameters from the M secondary carrier parameters supported by the 5G base station, sends the plurality of secondary carrier parameters to the 4G base station, and the 4G base station sends the plurality of secondary carrier parameters to the terminal, where the number of the plurality of secondary carrier parameters is not greater than N1, and the configuration step is performed K times, and N1, M, and K are all integers greater than or equal to 1.

[0046] In one example, the plurality of secondary carrier parameters are included in a configuration request message, that is, the 5G base station sends a configuration request containing the plurality of secondary carrier parameters to the 4G base station.

[0047] In one example, the method further includes: repeatedly performing the configuration step until all M secondary carrier parameters are sent to the terminal through the 4G base station. Through such a method, all the carrier parameters supported by the 5G base station can be configured to the terminal, enabling the terminal to use more carriers and improving data transmission performance.

[0048] In one example, when performing the configuration step each time, several carrier aggregation parameters read from the M carrier aggregation parameters are read without repetition, that is, the several carrier aggregation parameters that have been read in the previous execution of the configuration step are no longer read. For example, when performing the first configuration step, three carrier aggregation parameters A, B, and C are sent to the terminal through the 4G base station. When performing the second configuration step, any one of the carrier aggregation parameters A, B, or C is no longer sent to the 4G base station. By this method, it is possible to quickly send all the M carrier aggregation parameters supported by the 5G base station to the terminal.

[0049] In one example, after each execution of the configuration step, the 5G base station performs the configuration step again only after receiving a message from the terminal through the 4G base station indicating that the configuration of several carrier aggregation parameters has been successful. By this method, the 5G base station can confirm that the configuration step performed this time has enabled the terminal to successfully configure several carrier aggregation parameters.

[0050] In one example, the number of several carrier aggregation parameters is equal to N1. By this method, it is possible to quickly send all the M carrier aggregation parameters supported by the 5G base station to the terminal.

[0051] In one example, before performing the configuration step, the 5G base station sends the primary carrier parameter it supports to the terminal through the 4G base station, and the terminal configures the primary carrier parameter after receiving it.

[0052] In one example, before performing the configuration step, it further includes: receiving a base station connection request sent by another 4G base station through the current 4G base station, and obtaining the number N2 of carrier parameters supported by the other 4G base station from the base station connection request; when performing the first configuration step, sending several carrier aggregation parameters among the M carrier aggregation parameters supported by the 5G base station to the terminal through the 4G base station; wherein, the number of several carrier aggregation parameters is not greater than N1, including: sequentially sending several carrier aggregation parameters among the M carrier aggregation parameters supported by the 5G base station to the terminal through the current 4G base station and the other 4G base station; wherein, the number of several carrier aggregation parameters is not greater than min[N1, N2].

[0053] Specifically, during the movement of the terminal, the signal between the terminal and other 4G base stations may become weaker, while the signal between the terminal and the current 4G base station may become stronger. At this time, other 4G base stations can sense the change in signal strength through the terminal measurement report, and thus know that they need to switch to the current 4G base station. Therefore, other 4G base stations send a base station connection request including the number N2 of carrier parameters supported by other 4G base stations to the current 4G base station. The current 4G base station knows that it corresponds to the current 5G base station, so the current 4G base station sends a base station connection request including the number N2 of carrier parameters supported by other 4G base stations to the current 5G base station. The current 5G base station obtains the number N2 of carrier parameters supported by other 4G base stations from the base station connection request. When performing the configuration step for the first time, since the current 5G base station needs to communicate with the terminal through the current 4G base station and then through other 4G base stations, the number of carrier parameters sent by the current 5G base station needs to consider both the number N2 of carrier parameters supported by other 4G base stations and the number N1 of carrier parameters supported by the current 4G base station, that is, the number of several secondary carrier parameters is not greater than min[N1, N2]. By this method, when performing the configuration step for the first time, the number of carrier parameters supported by other 4G base stations and the current 4G base station are considered simultaneously, avoiding the problem that other 4G base stations or the current 4G base station cannot transmit carrier parameters, thereby realizing the configuration of carrier parameters.

[0054] In this embodiment, the 5G base station obtains the number N1 of carrier parameters supported by the 4G base station; performs a configuration step, and the configuration step includes: sending several of the M secondary carrier parameters supported by the 5G base station to the terminal through the 4G base station; wherein, the number of several secondary carrier parameters is not greater than N1, and the configuration step is performed K times, and N1, M, and K are all integers greater than or equal to 1. Since the number of several secondary carrier parameters is not greater than the number N1 of carrier parameters supported by the 4G base station, the problem that the 4G base station cannot transmit carrier parameters can be avoided as much as possible, thereby realizing the configuration of carrier parameters.

[0055] The second embodiment of the present invention relates to a carrier configuration method applied to a 4G base station. The specific flowchart is as Figure 4 shown and includes:

[0056] Step 201, receiving a base station handover request sent by the first 5G base station and including the number N1 of carrier parameters supported by the 4G base station; wherein, N1 is an integer greater than or equal to 1, and the base station handover request also indicates a handover from the first 5G base station to the second 5G base station.

[0057] Specifically, during the movement of the terminal, the signal between the terminal and the first 5G base station may become weak, while the signal between the terminal and the second 5G base station may become strong. At this time, the first 5G base station can sense the change in signal strength through the terminal measurement report, so as to know that it needs to switch to the second 5G base station. Other 5G base stations and the current 5G base station communicate with the terminal through the current 4G base station. The first 5G base station sends a base station handover request containing the number N1 of carrier parameters supported by the 4G base station to the 4G base station. N1 is an integer greater than or equal to 1, and the base station handover request also indicates the handover from the first 5G base station to the second 5G base station. In this way, after receiving the base station handover request, the 4G base station can know the number N1 of carrier parameters supported by itself and can know that the first 5G base station is to switch to the second 5G base station.

[0058] Step 202: Send a base station connection request containing the number N1 of carrier parameters supported by the 4G base station to the second 5G base station.

[0059] Step 203: Receive a configuration request containing P carrier parameters sent by the second 5G base station, and send a number of carrier parameters among the P carrier parameters to the terminal; where at least the secondary carrier parameters are included in the P carrier parameters, P is not greater than N1, and N1 and P are integers greater than or equal to 1.

[0060] Specifically, the 4G base station sends a base station connection request containing the number N1 of carrier parameters supported by the 4G base station to the second 5G base station. After receiving the base station connection request, the second 5G base station can know the number N1 of carrier parameters supported by the 4G base station, and reads P carrier parameters from the M carrier parameters supported by the second 5G base station itself. At least the secondary carrier parameters are included in the P carrier parameters, and a configuration request containing the P carrier parameters of the second 5G base station is sent to the 4G base station. P is not greater than N1, and P is an integer greater than or equal to 1.

[0061] After receiving the configuration request containing P carrier parameters sent by the second 5G base station, the 4G base station sends a configuration request containing a number of carrier parameters to the terminal. After receiving the configuration request, the terminal parses the configuration request to obtain a number of carrier parameters and performs the configuration of the number of carrier parameters; at this time, the first 5G base station successfully switches to the second 5G base station.

[0062] In an example, after the terminal successfully configures a number of carrier parameters, it will also send a message indicating the successful configuration of a number of carrier parameters to the 4G base station. After receiving the message indicating the successful configuration, the 4G base station sends a message indicating the successful base station handover and a message for content release to the first 5G base station, notifying the first 5G base station that the base station handover has been successfully performed, so that the first 5G base station releases the content of the terminal.

[0063] In one example, after the 4G base station receives messages indicating successful configuration of a number of carrier parameters in response, it responds to the second 5G base station with messages indicating successful configuration of the number of carrier parameters.

[0064] In one example, the method further includes: performing a configuration step, where the configuration step includes: sending a number of carrier parameters among the remaining carrier parameters supported by the second 5G base station to the terminal through the 4G base station; where the number of the number of carrier parameters is not greater than N1, the configuration step is performed K times, and N1, M, and K are all integers greater than or equal to 1. In one example, the configuration step is repeatedly performed until all M carrier parameters are sent to the terminal through the 4G base station. In one example, the second 5G base station only performs the configuration step again after receiving a message indicating successful configuration responded by the terminal through the 4G base station.

[0065] In this embodiment, during the process of the first 5G base station switching to the second 5G base station, P carrier parameters are carried at the same time, so that the terminal can obtain the carrier parameters relatively quickly, and thus the configuration of the carrier parameters can be performed relatively quickly.

[0066] The third embodiment of the present invention relates to a carrier configuration method applied to a first 4G base station. The specific flowchart is as Figure 5 shown, and includes:

[0067] Step 301: Send a base station connection request including the number N2 of carrier parameters supported by the first 4G base station to the second 5G base station through the second 4G base station.

[0068] Specifically, during the movement of the terminal, the signal between the terminal and the first 4G base station may become weak, while the signal between the terminal and the second 4G base station may become strong. At this time, the first 4G base station can sense the change in signal strength through the terminal measurement report, and thus knows that it needs to switch to the second 4G base station. Therefore, the first 4G base station sends a base station connection request including the number N2 of carrier parameters supported by the first 4G base station to the second 4G base station. The second 4G base station knows that it corresponds to the second 5G base station, so the second 4G base station sends a base station connection request including the number N2 of carrier parameters supported by the first 4G base station to the second 5G base station.

[0069] In one example, before step 301, it further includes: the first 4G base station sends a base station handover request to the first 5G base station. After receiving the base station handover request, the first 5G base station sends a reply agreeing to the base station handover including the number N2 of carrier parameters supported by the first 4G base station to the first 4G base station.

[0070] Step 302: Receive, via a second 4G base station, a configuration request including L carrier parameters sent by a second 5G base station, and send some of the L carrier parameters to a terminal; where at least the secondary carrier parameters are included in the L carrier parameters, L is not greater than N1, and L is an integer greater than or equal to 1.

[0071] In an example, first obtain the number N2 of carrier parameters supported by the second 4G base station, including: the second 5G base station sends a configuration request including L carrier parameters to the second 4G base station, L is not greater than N2, and at least the secondary carrier parameters are included in the L carrier parameters. If a message indicating that the configuration request processing fails and including the number N1 of carrier parameters supported by the second 4G base station is received, obtain the number N1 of carrier parameters supported by the second 4G base station; the second 5G base station then sends a configuration request including L carrier parameters to the second 4G base station. At this time, L is not greater than min[N1, N2]. The second 4G base station sends the configuration request including L carrier parameters to the first 4G base station. At this time, the first 4G base station successfully switches to the second 4G base station, and the first 5G base station successfully switches to the second 5G base station. The first 4G base station sends a configuration request including L carrier parameters to the terminal. After receiving the configuration request, the terminal parses the configuration request to obtain the L carrier parameters and performs the configuration of the L carrier parameters.

[0072] The second 5G base station sends a configuration request containing L carrier parameters to the second 4G base station, where L is not greater than N2. If a message indicating that the configuration request processing fails is received from the second 4G base station and the message does not contain the number of carrier parameters supported by the second 4G base station, or if no response is received from the second 4G base station within a preset duration, let the value of L in this time be less than the value of L in the previous time, and repeat the operation of obtaining the number of carrier parameters N1 supported by the second 4G base station until the second 5G base station receives a message indicating that the configuration request processing is successful from the second 4G base station. In an example, while the second 4G base station sends a message indicating that the configuration request processing is successful to the second 5G base station, it sends a configuration request containing the L carrier parameters in this time to the first 4G base station. At this time, the first 4G base station successfully switches to the second 4G base station, and the first 5G base station successfully switches to the second 5G base station. The first 4G base station sends a configuration request containing the L carrier parameters in this time to the terminal. After receiving the configuration request, the terminal parses the configuration request to obtain the L carrier parameters and configures the L carrier parameters. In an example, the message indicating that the configuration request processing is successful is a message indicating that the configuration of the L carrier parameters by the second 4G base station is successful. After receiving the configuration request containing the L carrier parameters in this time, if the number of carrier parameters supported by the second 4G base station is greater than or equal to L and the second 4G base station can process the configuration request, the second 4G base station sends the configuration request containing the L carrier parameters to the first 4G base station. At this time, the first 4G base station successfully switches to the second 4G base station, and the first 5G base station successfully switches to the second 5G base station. The first 4G base station sends the configuration request containing the L carrier parameters to the terminal. After receiving the configuration request, the terminal configures the L carrier parameters and sends a message indicating that the configuration of the L carrier parameters is successful to the second 4G base station. The second 4G base station sends the message indicating that the configuration of the L carrier parameters is successful to the 5G base station. The 5G base station receives the message indicating that the configuration of the L secondary carrier parameters is successful from the second 4G base station within the preset duration, and the number of carrier parameters N1 supported by the second 4G base station obtained is L in this time.

[0073] In one example, L is not greater than min[N1, N2], where N1 is the number of carrier parameters supported by the second 4G base station pre-stored in the second 5G base station. The second 5G base station knows that it corresponds to the second 4G base station, obtains the identifier of the second 4G base station from local, and queries the correspondence between the identifier and the number of carrier parameters stored locally in the second 5G base station to obtain the number of carrier parameters N1 supported by the second 4G base station. Since during the base station handover process, the second 5G base station needs to communicate with the terminal through the second 4G base station first and then through the first 4G base station, the number of carrier parameters sent by the second 5G base station needs to consider both the number of carrier parameters N2 supported by the first 4G base station and the number of carrier parameters N1 supported by the second 4G base station. Therefore, L is not greater than min[N1, N2], and at least the secondary carrier parameters are included in the L carrier parameters, that is, the configuration request containing L carrier parameters sent by the second 5G base station to the second 4G base station; where L is not greater than min[N1, N2], and the second 4G base station sends the configuration request containing L carrier parameters to the first 4G base station. At this time, the first 4G base station successfully switches to the second 4G base station, and the first 5G base station successfully switches to the second 5G base station. The first 4G base station sends a configuration request containing L carrier parameters to the terminal. After receiving the configuration request, the terminal parses the configuration request to obtain L carrier parameters and performs the configuration of the L carrier parameters. Through such a method, during the process of the first 5G base station switching to the second 5G base station and the first 4G base station switching to the second 4G base station, when the number of carrier parameters supported by the second 4G base station pre-stored in the second 5G base station is considered, the number of carrier parameters supported by both the first 4G base station and the second 4G base station is taken into account, realizing the configuration of carrier parameters.

[0074] In one example, after the first 4G base station receives the configuration request containing L carrier parameters, the method further includes: the first 4G base station sends a base station release request to the first 5G base station, and the first 5G base station responds with a message agreeing to the base station release to the first 4G base station.

[0075] In one example, after the terminal successfully configures L carrier parameters, it will also respond with a message indicating successful configuration of L carrier parameters to the second 4G base station. After receiving the message indicating successful configuration, the second 4G base station sends a message indicating successful configuration to the second 5G base station.

[0076] In one example, after the terminal successfully configures L carrier parameters, the second 4G base station sends a content release message to the first 4G base station, and the first 4G base station sends the content release message to the first 5G base station to cause the first 5G base station to release the terminal content.

[0077] In one example, the method further includes: performing a configuration step, where the configuration step includes: sending a plurality of carrier parameters among the remaining carrier parameters supported by the second 5G base station to the terminal through the second 4G base station; where the number of the plurality of carrier parameters is not greater than N1, and the configuration step is performed K times, and N1, M, and K are all integers greater than or equal to 1. In one example, the configuration step is repeatedly performed until all M secondary carrier parameters are sent to the terminal through the second 4G base station. In one example, the second 5G base station performs the configuration step again only after receiving a message indicating successful configuration responded by the terminal through the second 4G base station.

[0078] In this embodiment, during the process of the first 5G base station switching to the second 5G base station and the first 4G base station switching to the second 4G base station, L carrier parameters are carried simultaneously, so that the terminal can obtain the carrier parameters more quickly, and thus the configuration of the carrier parameters can be performed more quickly.
