Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the present invention relates to a carrier configuration method, which is applied to a 5G base station. The specific process is shown in fig. 1, and comprises the following steps:
Specifically, if the terminal needs to use the carrier parameter of the 5G base station for data transmission, the terminal needs to configure the carrier parameter supported by the 5G base station locally, and since the 5G base station needs to communicate with the terminal through the 4G base station, and the number of transmitted auxiliary carrier parameters is limited by the number of carrier parameters supported by the 4G base station in the process that the 5G base station transmits the carrier parameter to the terminal, the 5G base station needs to acquire the number N1 of the carrier parameters supported by the 4G base station first.
In an example, a specific flowchart of obtaining the number N1 of carrier parameters supported by the 4G base station is shown in fig. 2, and includes:
In step 1012, the number N1 of carrier parameters supported by the 4G base station is obtained from the base station connection request.
Specifically, during the moving process of the terminal, signals between the terminal and other 5G base stations may become weak, and signals between the terminal and the current 5G base station may become strong, at this time, the other 5G base stations may perceive the change of the signal strength through the terminal measurement report, so as to know that the handover to the current 5G base station is required, and the other 5G base stations and the current 5G base station both communicate with the terminal through the current 4G base station. Other 5G base stations firstly send base station switching requests 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 switching requests also indicate switching from other 5G base stations to the current 5G base station, so after the 4G base station receives the base station switching requests, the base station connection requests containing the number N1 of carrier parameters supported by the 4G base station are sent to the current 5G base station, and the current 5G base station receives the number N1 of carrier parameters supported by the 4G base station and sent by the 4G base station. The 5G base station analyzes the base station connection request to obtain the number N1 of carrier parameters supported by the 4G base station.
By such a method, the number N1 of carrier parameters supported by the 4G base station can be directly acquired from the 4G base station, and the number of carrier parameters supported by the 4G base station can be acquired relatively quickly.
In an example, a specific flowchart of obtaining the number N1 of carrier parameters supported by the 4G base station is shown in fig. 3, and includes:
Specifically, the 5G base station reads Z secondary carrier parameters from the M secondary carrier parameters supported, and sends a configuration request including 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 is M for the first time, that is, the 5G base station sends the configuration request including M secondary carrier parameters to the 4G base station. By the method, when the number of the carrier parameters supported by the 4G base station is M, the trial is started from the maximum number M, so that the number M of the carrier parameters supported by the 4G base station can be acquired more accurately.
In step 1015, whether the received response of the 4G base station is a message indicating that the configuration request processing is successful. If yes, go to step 1018, if no, go to step 1016,
in step 1016, the received message indicating that the configuration request processing failed responded by the 4G base station includes the number of the carrier parameters supported by the 4G base station. If yes, go to step 1018, otherwise, go to step 1017.
In step 1018, the number N1 of carrier parameters supported by the 4G base station is obtained.
Specifically, after the 4G base station receives the configuration request including 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 cannot send the configuration request to the terminal, and 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 that the configuration request processing fails. The 5G base station may set a preset time length according to actual needs, and if the 5G base station does not receive a response from the 4G base station within the preset time length, or receives a message indicating that the processing of the configuration request failed, which is responded by the 4G base station, the value of Z this time is smaller than the value of Z last time, and the process enters step 1013 again.
If the 5G base station receives a response within a preset time length and responds a message for representing the configuration request processing failure, the 5G base station analyzes the message for representing the configuration request processing failure, and if the message for representing the configuration request processing failure contains the number N1 of the carrier parameters supported by the 4G base station, the number N1 of the carrier parameters supported by the 4G base station is directly obtained; if the message indicating that the processing of the configuration request fails does not contain the number of the carrier parameters supported by the 4G base station, the value of the Z of this time is smaller than the value of the Z of the last time, and the process enters step 1013 again.
In an example, the value of the Z at this time is obtained by subtracting 1 from the value of the Z at the last time, so that the values of the Z are sequentially obtained, the adjustment step size of the value of the Z is smaller, and the number of carrier parameters supported by the 4G base station can be accurately obtained.
In an example, the value of Z at this time is an integer obtained by dividing the value of Z at the last time by n, where n is an integer greater than or equal to 2.
In one example, after receiving a configuration request including Z auxiliary 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 may process the configuration request, and the 4G base station sends the configuration request including the Z auxiliary carrier parameters to the terminal and responds a message indicating that the configuration request is successfully processed to the 5G base station; and the 5G base station receives the message of successful processing of the characterization configuration request responded by the 4G base station in the preset time length, and the number N1 of the carrier parameters supported by the 4G base station is obtained as Z.
In one example, the message that characterizes the successful processing of the configuration request is a successful configuration message of Z secondary carrier parameters responded by the 4G base station. After the 4G base station receives the configuration request including the Z auxiliary carrier parameters, if the number of the carrier parameters supported by the 4G base station is greater than or equal to Z, the 4G base station may process the configuration request, the 4G base station sends the configuration request including the Z auxiliary carrier parameters to the terminal, the terminal configures the Z auxiliary carrier parameters after receiving the configuration request, and responds a configuration success message of the Z auxiliary carrier parameters to the 4G base station, the 4G base station sends the configuration success message of the Z auxiliary carrier parameters responded by the 4G base station to the 5G base station, the 5G base station receives the configuration success message of the Z auxiliary carrier parameters responded by the 4G base station within a preset time length, and obtains the number N1 of the carrier parameters supported by the 4G base station as Z this time.
By the method, the number of the carrier parameters supported by the 4G base station can be accurately acquired by utilizing multiple message interactions.
In one example, obtaining the number N1 of carrier parameters supported by the 4G base station includes: the 5G base station locally stores the identifications of a plurality of 4G base stations, and since the 5G base station knows which 4G base station is connected with the 5G base station, the 5G base station can acquire the identifications of the 4G base stations from the local. Inquiring the corresponding relation between the identifier locally stored in the 5G base station and the number of the carrier parameters according to the identifier, and if the number of the carrier parameters corresponding to the identifier of the 4G base station is inquired, acquiring the number N1 of the carrier parameters supported by the 4G base station; if the number of the carrier parameters corresponding to the identifier of the 4G base station is not inquired, the 5G base station acquires the number of the carrier parameters supported by the 4G base station by utilizing the interaction of multiple messages.
In one example, obtaining the number N1 of carrier parameters supported by the 4G base station includes: the 5G base station locally stores the identifications of a plurality of 4G base stations, and since the 5G base station knows which 4G base station is connected with the 5G base station, the 5G base station can acquire the identifications of the 4G base stations from the local. The 5G base station sends a request message containing the 4G base station identifier to external network management equipment, the external network management equipment inquires the corresponding relation between the locally stored identifier of the external network management equipment and the number of the carrier parameters, if the number of the carrier parameters corresponding to the identifier of the 4G base station is inquired, the number N1 of the carrier parameters supported by the 4G base station is obtained, and the message containing the number N1 of the 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 the carrier parameters supported by the 4G base station; if the number of the carrier parameters corresponding to the identifier of the 4G base station is not inquired, the external network management equipment responds to the inquiry failure message to the 5G base station, and the 5G base station acquires the number of the carrier parameters supported by the 4G base station by utilizing the interaction of multiple messages. The corresponding relation between the locally stored identification of the external network management equipment and the number of the carrier parameters is preset manually. By the method, the number N1 of the carrier parameters supported by the 4G base station can be acquired quickly.
Specifically, the 5G base station reads a plurality of auxiliary carrier parameters from M auxiliary carrier parameters supported by the 5G base station, sends the plurality of auxiliary carrier parameters to the 4G base station, and the 4G base station sends the plurality of auxiliary carrier parameters to the terminal, wherein the number of the plurality of auxiliary carrier parameters is not greater than N1, the configuration step is performed K times, and N1 and M, K are integers greater than or equal to 1.
In one example, several secondary carrier parameters are included in the message of the configuration request, that is, the 5G base station sends the configuration request including several secondary carrier parameters to the 4G base station.
In one example, the method further comprises: and repeating the configuration step until all the M auxiliary carrier parameters are sent to the terminal through the 4G base station. By the method, all carrier parameters supported by the 5G base station can be configured to the terminal, so that more carriers can be used by the terminal, and the data transmission performance can be improved.
In one example, each time the configuration step is performed, the number of secondary carrier parameters read from the M secondary carrier parameters is not repeatedly read, that is, the number of secondary carrier parameters that have been read in the last time the configuration step was performed is not read any more. For example: and when the first configuration step is executed, A, B, C three auxiliary carrier parameters are sent to the terminal through the 4G base station, and when the second configuration step is executed, any one of A, B or C auxiliary carrier parameters is not sent to the 4G base station any more. By the method, all M auxiliary carrier parameters supported by the 5G base station can be quickly transmitted to the terminal.
In one example, after each configuration step is performed, the 5G base station performs the configuration step again after receiving a message that the configuration of the parameters of the plurality of secondary carriers responded by the terminal through the 4G base station is successful. By such a method, the 5G base station can confirm that the configuration step executed this time has enabled the terminal to successfully configure the parameters of the several secondary carriers.
In one example, the number of the secondary carrier parameters is equal to N1, and in this way, all M secondary carrier parameters supported by the 5G base station can be transmitted to the terminal in a faster manner.
In one example, before the configuring step is performed, the 5G base station sends the main carrier parameters supported by the 5G base station to the terminal through the 4G base station, and the terminal performs the configuration of the main carrier parameters after receiving the main carrier parameters.
In one example, before the configuring step, the method further comprises: receiving a base station connection request sent by other 4G base stations through the current 4G base station, and acquiring the number N2 of carrier parameters supported by other 4G base stations from the base station connection request; when the configuration step is executed for the first time, a plurality of auxiliary carrier parameters in M auxiliary carrier parameters supported by the 5G base station are sent to the terminal through the 4G base station; wherein, the number of a plurality of auxiliary carrier parameters is not more than N1, including: a plurality of auxiliary carrier parameters in M auxiliary carrier parameters supported by the 5G base station are sequentially transmitted to the terminal through the current 4G base station and other 4G base stations; wherein the number of the plurality of secondary carrier parameters is not more than min [ N1, N2 ].
Specifically, when the terminal moves, signals between the terminal and other 4G base stations may become weak, and signals between the terminal and the current 4G base station may become strong, and at this time, the other 4G base stations may sense a change in signal strength through a terminal measurement report, and thus know that a handover to the current 4G base station is required, so that the other 4G base stations send a base station connection request including the number N2 of carrier parameters supported by the other 4G base stations to the current 4G base station, and the current 4G base station knows that the current 4G base station corresponds to the current 5G base station, so that the current 4G base station sends a base station connection request including the number N2 of carrier parameters supported by the other 4G base stations to the current 5G base station, and the current 5G base station obtains the number N2 of carrier parameters supported by the other 4G base stations from the base station connection request. When the configuration step is performed 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 the other 4G base stations, the number of carrier parameters transmitted by the current 5G base station needs to consider the number N2 of carrier parameters supported by the other 4G base stations and the number N1 of carrier parameters supported by the current 4G base station at the same time, that is, the number of several secondary carrier parameters is not greater than min [ N1, N2 ]. By the method, when the configuration step is executed for the first time, the number of the carrier parameters supported by other 4G base stations and the current 4G base station is considered, so that the problem that the other 4G base stations or the current 4G base station cannot transmit the carrier parameters is avoided, and the configuration of the carrier parameters is realized.
In this embodiment, the 5G base station obtains the number N1 of carrier parameters supported by the 4G base station; performing a configuration step, the configuration step comprising: sending a plurality of auxiliary carrier parameters in M auxiliary carrier parameters supported by the 5G base station to the terminal through the 4G base station; the number of the secondary carrier parameters is not more than N1, the configuration step is executed K times, and N1 and M, K are integers which are both more than or equal to 1. Because the number of the plurality of auxiliary carrier parameters is not greater than the number N1 of the carrier parameters supported by the 4G base station, the problem that the 4G base station cannot transmit the carrier parameters can be avoided as much as possible, and the configuration of the carrier parameters is realized.
A second embodiment of the present invention relates to a carrier configuration method, which is applied to a 4G base station, and a specific flowchart is shown in fig. 4, where the method includes:
Specifically, during the moving process of the terminal, the signal between the terminal and the first 5G base station may become weak, and the signal between the terminal and the second 5G base station may become strong, at this time, the first 5G base station may sense the change of the signal strength through the terminal measurement report, so as to know that the handover to the second 5G base station is required, and the other 5G base stations and the current 5G base station all communicate with the terminal through the current 4G base station. The first 5G base station sends a base station switching request containing the number N1 of carrier parameters supported by the 4G base station to the 4G base station, wherein N1 is an integer greater than or equal to 1, and the base station switching request further indicates switching from the first 5G base station to the second 5G base station, so that after the 4G base station receives the base station switching request, the 4G base station can know the number N1 of carrier parameters supported by the 4G base station and can know that the first 5G base station is to be switched to the second 5G base station.
Specifically, the 4G base station sends a base station connection request including the number N1 of carrier parameters supported by the 4G base station to the second 5G base station, the second 5G base station can know the number N1 of carrier parameters supported by the 4G base station after receiving the base station connection request, and reads P carrier parameters from M carrier parameters supported by the second 5G base station itself, where the P carrier parameters at least include a secondary carrier parameter, and sends a configuration request including P carrier parameters of the second 5G base station to the 4G base station, where P is not greater than N1, and P is an integer greater than or equal to 1.
After receiving a configuration request of P carrier parameters sent by a second 5G base station, a 4G base station sends a configuration request containing a plurality of carrier parameters to a terminal, and after receiving the configuration request, the terminal analyzes the configuration request to obtain a plurality of carrier parameters and configures the plurality of carrier parameters; at this time, the first 5G base station is successfully handed over to the second 5G base station.
In an example, after the terminal successfully configures the plurality of carrier parameters, the terminal also responds a message that the configuration of the plurality of carrier parameters is successful to the 4G base station, and after the 4G base station receives the message that the configuration is successful, the 4G base station sends a message that the base station is successfully switched and a message that the content is released to the first 5G base station, and notifies the first 5G base station that the base station is successfully switched, so that the first 5G base station releases the content of the terminal.
In one example, after receiving the responded messages of successful configuration of the plurality of carrier parameters, the 4G base station responds to the second 5G base station of successful configuration of the plurality of carrier parameters.
In one example, the method further comprises: performing a configuration step, the configuration step comprising: sending a plurality of carrier parameters in the rest carrier parameters supported by the second 5G base station to the terminal through the 4G base station; the number of the carrier parameters is not more than N1, the configuration step is executed K times, and N1 and M, K are integers which are both more than or equal to 1. In one example, the configuring step is repeated until all M carrier parameters are transmitted to the terminal through the 4G base station. In one example, the second 5G base station performs the configuration step again after receiving the message that the configuration is successful and the terminal responds through the 4G base station.
In this embodiment, in the process of switching from the first 5G base station to the second 5G base station, P carrier parameters are simultaneously carried, so that the terminal can obtain the carrier parameters more quickly, and thus the carrier parameters can be configured more quickly.
A third embodiment of the present invention relates to a carrier configuration method applied to a first 4G base station, and a specific flowchart is shown in fig. 5, where the method includes:
Specifically, when the terminal moves, the signal between the terminal and the first 4G base station may become weak, and the signal between the terminal and the second 4G base station may become strong, and at this time, the first 4G base station may perceive the change in signal strength through the terminal measurement report, and thus knows that a handover to the second 4G base station is required, so the first 4G base station transmits 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, and the second 4G base station knows that it corresponds to the second 5G base station, so the second 4G base station transmits 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.
In one example, before step 301, the method further includes: and the first 4G base station sends a base station switching request to the first 5G base station, and the first 5G base station sends a response of agreeing to base station switching, which contains the number N2 of the carrier parameters supported by the first 4G base station, to the first 4G base station after receiving the base station switching request.
In one example, obtaining the number N2 of carrier parameters supported by the second 4G base station first includes: the second 5G base station sends a configuration request containing L carrier parameters to the second 4G base station, wherein L is not more than N2, the L carrier parameters at least comprise auxiliary carrier parameters, and if a message which indicates that the configuration request processing fails and is responded by the second 4G base station is received, and the message contains the number N1 of the carrier parameters supported by the second 4G base station, the number N1 of the carrier parameters supported by the second 4G base station is obtained; and the second 5G base station sends a configuration request containing L carrier parameters to the second 4G base station, wherein L is not more than min [ N1, N2], the second 4G base station sends the configuration request containing L carrier parameters to the first 4G base station, at the moment, the first 4G base station is successfully switched to the second 4G base station, and the first 5G base station is successfully switched to the second 5G base station. And the first 4G base station sends a configuration request containing L carrier parameters to the terminal, and the terminal analyzes the configuration request to obtain the L carrier parameters after receiving the configuration request and configures the L carrier parameters.
And the second 5G base station sends a configuration request containing L carrier parameters to the second 4G base station, wherein L is not more than N2, if a message indicating that the processing of the configuration request responded by the second 4G base station fails is received and the message does not contain the number of the carrier parameters supported by the second 4G base station, or if the response of the second 4G base station is not received within a preset time length, the value of the L at this time is smaller than the value of the L at the last time, and the step of repeatedly obtaining the number N1 of the carrier parameters supported by the second 4G base station is carried out until the second 5G base station obtains the message indicating that the processing of the configuration request responded by the second 4G base station succeeds. In one example, the second 4G base station responds to the message indicating that the configuration request processing is successful and sends the configuration request including the current L carrier parameters to the first 4G base station, at this time, the first 4G base station is successfully switched to the second 4G base station, and the first 5G base station is successfully switched to the second 5G base station. The first 4G base station comprises a configuration request of the L carrier parameters to the terminal, and the terminal analyzes the configuration request to obtain the L carrier parameters after receiving the configuration request and configures the L carrier parameters. In one example, the message indicating that the configuration request processing is successful is a configuration success message of L carrier parameters responded by the second 4G base station. After the second 4G base station receives the configuration request including the current L carrier parameters, if the number of the carrier parameters supported by the second 4G base station is greater than or equal to L, the second 4G base station may process the configuration request, the second 4G base station sends the configuration request including the L carrier parameters to the first 4G base station, at this time, the first 4G base station is successfully switched to the second 4G base station, and the first 5G base station is successfully switched to the second 5G base station. The first 4G base station sends a configuration request containing L carrier parameters to a terminal, the terminal configures the L carrier parameters after receiving the configuration request and responds a configuration success message of the L carrier parameters to the second 4G base station, the second 4G base station sends the configuration success message of the responded L carrier parameters to the 5G base station, the 5G base station receives the configuration success message of the L auxiliary carrier parameters responded by the second 4G base station within a preset time length, and the N1 of the carrier parameters supported by the second 4G base station is obtained as the current L.
In one example, L is not greater than min N1, N2, N1 is the number of carrier parameters supported by the second 4G base station that the second 5G base station previously stored. The second 5G base station knows that it corresponds to the second 4G base station, acquires the identifier of the second 4G base station from the local, queries the correspondence between the identifier stored locally by the second 5G base station and the number of the carrier parameters, and acquires the number N1 of the carrier parameters supported by the second 4G base station. In the process of switching base stations, 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, so that the number of carrier parameters sent by the second 5G base station needs to consider the number N2 of carrier parameters supported by the first 4G base station and the number N1 of carrier parameters supported by the second 4G base station at the same time, so that L is not greater than min [ N1, N2], and the L carrier parameters at least include secondary carrier parameters, that is, a configuration request containing L carrier parameters sent by the second 5G base station to the second 4G base station; wherein, L is not more than min [ N1, N2], the second 4G base station sends a configuration request containing L carrier parameters to the first 4G base station, at this time, the first 4G base station is successfully switched to the second 4G base station, and the first 5G base station is successfully switched to the second 5G base station. And the first 4G base station sends a configuration request containing L carrier parameters to the terminal, and the terminal analyzes the configuration request to obtain the L carrier parameters after receiving the configuration request and configures the L carrier parameters. By the method, in the process of switching the first 5G base station to the second 5G base station and switching the first 4G base station to the second 4G base station, when the number of the carrier parameters supported by the second 4G base station, which is pre-stored by the second 5G base station, is taken into account, the number of the carrier parameters supported by the first 4G base station and the second 4G base station is taken into account, and the configuration of the carrier parameters is realized.
In one example, after the first 4G base station receives the configuration request containing the L carrier parameters, the method further includes: and the first 4G base station sends a base station release request to the first 5G base station, and the first 5G base station responds to a message that the first 4G base station agrees to the base station release.
In an example, after the terminal successfully configures the L carrier parameters, the terminal also responds to the second 4G base station with a message that the configuration of the L carrier parameters is successful, and after the second 4G base station receives the message that the configuration is successful, the second 4G base station sends the message that the configuration is successful to the second 5G base station.
In one example, after the terminal successfully configures the 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, so that the first 5G base station releases the content of the terminal.
In one example, the method further comprises: performing a configuration step, the configuration step comprising: a plurality of carrier parameters in the rest carrier parameters supported by the second 5G base station are sent to the terminal through the second 4G base station; the number of the carrier parameters is not more than N1, the configuration step is executed K times, and N1 and M, K are integers which are both more than or equal to 1. In one example, the configuring step is repeatedly performed until all M secondary carrier parameters are transmitted to the terminal through the second 4G base station. In one example, the second 5G base station performs the configuration step again after receiving the message that the configuration is successful and the terminal responds through the second 4G base station.
In this embodiment, in the process of switching the first 5G base station to the second 5G base station and switching the first 4G base station to the second 4G base station, L carrier parameters are simultaneously carried, so that the terminal can obtain the carrier parameters faster, and thus the carrier parameters can be configured faster.
