[0051] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0052] Before describing the embodiments of the present invention, the assembly method of the BBU is described first.

[0053] BBU stands for base band unit. One base station corresponds to one BBU. One BBU consists of a power module, a main control board and a baseband board installed in a BBU frame. There are generally two main control boards and a maximum of six baseband boards. As a physical component for carrier frequency processing, a baseband board can support several logical carrier frequencies. Different types of baseband boards support different numbers of carrier frequencies, such as 3 or 6. When the BBU is working, a certain number of carrier frequencies needs to be configured, that is, the number of carrier frequencies supported by the baseband board needs to be occupied. When it is not fully occupied, there will be vacant carrier frequencies.

[0054] In the CRAN mode, the BBUs corresponding to multiple base stations are installed in a centralized computer room. There are several racks in a centralized computer room. Figure 1As shown, multiple BBU frames are installed. Each BBU frame has a certain number of baseband board slots, which are used to install baseband boards. Usually, the baseband boards of each BBU are not fully installed, that is, there are empty baseband board slots in the BBU frame. BBU merging means installing the baseband boards in multiple base station BBUs into one BBU frame and merging them into one BBU.

[0055] The CRAN model includes a green wireless access network architecture (Clean system) of centralized processing, collaborative radio and real-time cloud computing architecture (Real-time Cloud Infrastructure). Its essence is to achieve low-cost, high-bandwidth and flexible operations by reducing the number of base station rooms, reducing energy consumption, adopting collaborative and virtualized technologies, realizing resource sharing and dynamic scheduling, and improving spectrum efficiency.

[0056] Figure 2 The flowchart of the BBU merging method provided by the embodiment of the present invention is shown, and the method is executed by a computer processing device. The computer processing device may include a mobile phone, a laptop computer, etc. Figure 2 As shown, the method comprises the following steps:

[0057] Step 101: Obtain configured baseband board information, configured carrier frequency information, and maximum supported baseband board information corresponding to multiple BBUs to be merged.

[0058] In one embodiment of the present invention, a BBU to be merged refers to a BBU before merging. Figure 1 The configured baseband board information includes the number of baseband boards configured in the BBU, the types of each configured baseband board, etc. The configured carrier frequency information includes the number of carrier frequencies configured in the BBU, and the maximum supported baseband board information includes the maximum number of baseband boards that can be installed in the BBU frame.

[0059] Step 102: The BBUs to be merged are merged according to the maximum supported baseband board information and the configured baseband board information to obtain an initial BBU merging sequence.

[0060] In one embodiment of the present invention, taking into account that when merging the BBUs of various frames, the total number of configured baseband boards of the BBUs in the merged frames cannot exceed the maximum number of baseband boards that the frame can support, that is, it is necessary to ensure that when the first BBU is merged into the second BBU, the number of vacant baseband board slots in the second BBU is greater than the number of configured baseband boards of the first BBU, otherwise the baseband boards of the BBU will have nowhere to be installed, resulting in the loss of baseband resources after the merger and the BBU being unable to work normally.

[0061] In another embodiment of the present invention, the initial BBU merging sequence includes at least one initial BBU group, and the initial BBU group includes at least one of the BBUs to be merged. The maximum supported baseband board information includes the maximum number of supported baseband boards; the configured baseband board information includes the number of configured baseband boards of the BBUs to be merged. Among them, an initial BBU group corresponds to a BBU frame, and the initial BBU merging sequence includes the identifiers of each BBU to be merged included in each initial BBU group.

[0062] For example, as shown in Table 1, there may be 6 BBUs to be merged, which are respectively recorded as BBU1-BBU6.

[0063]

[0064] Table 1

[0065] Step 102 also includes:

[0066] Step 1021: randomly merge the BBUs to be merged to obtain multiple optional BBU merging sequences; the optional BBU merging sequences include at least one optional BBU group, and the optional BBU group includes at least one BBU to be merged.

[0067] In one embodiment of the present invention, the BBUs to be merged are randomly merged until all the combinations of the BBUs to be merged are traversed to obtain an optional BBU merging sequence.

[0068] Referring to Table 1, an optional BBU merging sequence may be (1, 3), (2, 4, 5, 6); wherein 1-6 are identifiers of the BBUs to be merged, wherein (1, 3) and (2, 4, 5, 6) are an optional BBU group, the BBUs to be merged included in the optional BBU group (1, 3) are BBU1 and BBU3, and the BBUs to be merged included in (2, 4, 5, 6) are deduced according to the identifiers.

[0069] Step 1022: Determine the total number of configured baseband boards of each of the optional BBU groups according to the number of the configured baseband boards.

[0070] In one embodiment of the present invention, the sum of the numbers of configured baseband boards of the to-be-merged BBUs in each optional BBU group is determined as the total number of configured baseband boards in each optional BBU group.

[0071] As shown in Table 1, the total number of configured baseband boards corresponding to (1, 3) and (2, 4, 5, 6) is 2+2=4 and 1+1+1+3=6 respectively.

[0072] Step 1023: Determine the initial BBU merging sequence from the optional BBU merging sequence according to the total number of configured baseband boards and the maximum number of supported baseband boards.

[0073] In one embodiment of the present invention, the total number of configured baseband boards is compared with the maximum number of supported baseband boards, and any one of the optional BBU merging sequences in which the total number of configured baseband boards of all optional BBUs is not greater than the maximum number of supported baseband boards is determined as the initial BBU merging sequence.

[0074] For example, if there is an optional BBU merging sequence of (1, 2), (3, 4, 5, 6); then the total number of configured baseband boards corresponding to (1, 2), (3, 4, 5, 6) is 2+1=3, 2+1+1+3=7 respectively, and the maximum number of baseband boards supported by a BBU frame can be 6, 7 is greater than 6, indicating that the BBU3-BBU6 to be merged cannot be installed in the same BBU frame, that is, they cannot be merged. Therefore, (1, 2), (3, 4, 5, 6) cannot be used as the initial BBU merging sequence.

[0075] Step 103: Determine the maximum total number of baseband boards that can be saved in the initial BBU merging sequence according to the configured baseband board information and the configured carrier frequency information.

[0076] In one embodiment of the present invention, the configured baseband board information includes the number of configured baseband board types of each BBU to be merged and the total number of supportable carrier frequencies of each configured baseband board; the configured carrier frequency information includes the number of configured carrier frequencies of each BBU to be merged.

[0077] When the total number of carrier frequencies supported by the configured baseband board is greater than the number of configured carrier frequencies of the baseband board, it means that the baseband board has redundant carrier frequencies that can be provided to other BBUs to be merged. At the same time, since the total number of carrier frequencies supported by different types of baseband boards is different, whether the first BBU to be merged can be merged into the second BBU serving as the basis for the merger is determined based on the type of baseband boards specifically included in each first BBU to be merged.

[0078] Therefore, in another embodiment of the present invention, the configured baseband board information also includes the maximum number of supported carrier frequencies of each of the configured baseband boards; wherein the maximum number of supported carrier frequencies of different configured baseband boards varies depending on the type of the configured baseband boards, and may be 3 or 6, etc.

[0079] Step 103 also includes: Step 1031: determining the total maximum number of carrier frequencies supported by each of the BBUs to be merged according to the maximum number of carrier frequencies supported by the configured baseband boards.

[0080] In one embodiment of the present invention, the sum of the maximum number of supported carrier frequencies of all configured baseband boards in the BBU to be merged is determined as the total maximum number of supported carrier frequencies of the BBU to be merged. For example, for BBU1 in Table 1, the total maximum number of supported carrier frequencies is 3+3=6, and for BBU3 in Table 1, the total maximum number of supported carrier frequencies is 6+3=9.

[0081] Step 1032: Determine the number of redundant carrier frequencies of each of the BBUs to be merged according to the maximum total number of supported carrier frequencies and the configured carrier frequency information.

[0082] In one embodiment of the present invention, the difference between the maximum total number of supported carrier frequencies and the total number of configured carrier frequencies is determined as the number of redundant carrier frequencies of each BBU to be merged. For example, for BBU1 in Table 1, its number of redundant carrier frequencies is 6-4=2, and for BBU4 in Table 1, its maximum total number of supported carrier frequencies is 3-3=0.

[0083] Step 1033: Determine the maximum total number of baseband boards that can be saved in the initial BBU merging sequence according to the number of redundant carrier frequencies and the maximum number of supported carrier frequencies.

[0084] In one embodiment of the present invention, the total number of baseband boards that can be saved by merging each BBU to be merged into an initial BBU group in the initial BBU merging sequence is calculated respectively, and for each initial BBU group, the initial total number of baseband boards that can be saved in the initial BBU group after merging all the BBUs to be merged and the initial BBU is traversed in turn, and the BBU to be merged is merged into the initial BBU group with the largest total number of initial baseband boards that can be saved, and then the maximum total number of baseband boards that can be saved in the initial BBU merging sequence is determined according to the number of baseband boards that can be saved in each initial BBU group after the merger.

[0085] In yet another embodiment of the present invention, step 1033 further includes:

[0086] Step 331: Determine the initial number of baseband boards that can be saved in each of the initial BBU groups after the BBU to be merged is merged into each of the initial BBU groups based on the number of redundant carrier frequencies and the maximum number of supported carrier frequencies; wherein the number of configured baseband boards in each of the initial BBU groups after the merger is not greater than the maximum number of supported baseband boards.

[0087] In one embodiment of the present invention, the initial savable baseband board of the initial BBU group is determined according to the number of configured carrier frequencies and the number of supportable carrier frequencies of all the BBUs to be merged in the initial BBU group.

[0088] Specifically, with the restriction condition that the number of configured baseband boards in each of the initial BBU groups after the merger is not greater than the maximum number of supported baseband boards, the first adaptation algorithm can be adopted to merge the BBUs to be merged, that is, all the BBUs to be merged in the initial BBU merger sequence are taken out, and then all the BBUs to be merged are placed in each initial BBU group in sequence according to their order in the initial BBU merger sequence.

[0089] For each BBU to be merged, determine whether at least one baseband board can be saved after the merger, thereby obtaining the number of baseband boards that can be saved in the merged initial BBU group, and then check whether the number of redundant carrier frequencies of the initial BBU group is not less than the number of configured carrier frequencies of the BBU to be merged. If so, merge the BBU into the initial BBU group; if not, add an empty initial BBU group and put the above BBU to be merged into the newly added initial BBU group until all BBUs to be merged are merged. Therefore, the maximum number of baseband boards that can be saved is only related to the arrangement order of the BBUs to be merged in the initial BBU merger sequence.

[0090] In one embodiment of the present invention, step 331 further includes:

[0091] Step 3311: Determine the total number of redundant carrier frequencies of each of the initial BBU groups according to the number of redundant carrier frequencies.

[0092] In one embodiment of the present invention, the sum of the redundant carrier frequencies of all the BBUs to be merged in the initial BBU group is determined as the total number of redundant carrier frequencies of each initial BBU group.

[0093] Step 3312: Determine the ratio of the total number of redundant carrier frequencies to the maximum number of supported carrier frequencies.

[0094] In one embodiment of the present invention, the maximum number of supported carrier frequencies is the maximum number of supported carrier frequencies of the baseband board to be placed in the BBU to be merged that currently needs to be merged. As shown in Table 1, when each initial BBU group is placed in BBU6, the maximum number of supported carrier frequencies of the baseband board 1 configured in BBU6 is 3, and the maximum number of supported carrier frequencies of the baseband board 1 configured in BBU6 is 6.

[0095] For example, for BBU2, when the baseband board 1 configured with two carriers is merged into the initial BBU group (1), the total number of redundant carrier frequencies is (3+3+3)-(4+2)=3, and the ratio is 3 / 3=1.

[0096] Step 3313: round down the ratio to obtain the number of baseband boards that can be saved corresponding to each of the initial BBU groups.

[0097] In one embodiment of the present invention, when the number of redundant carrier frequencies is less than the maximum number of carrier frequencies supported by a single baseband board, it indicates that there is at least one configured carrier frequency on the single baseband board, so the baseband board cannot be completely saved. Therefore, in order to avoid the loss of the number of configured carrier frequencies after merging, the ratio is rounded down to obtain the number of baseband boards that can be saved corresponding to each of the initial BBU groups.

[0098] Step 332: Merge each of the BBUs to be merged into the initial BBU group with the largest number of initially saveable baseband boards.

[0099] As mentioned above, according to the first adaptation algorithm, each BBU to be merged is assigned to the initial BBU group that can save the most baseband boards at present, until all the BBUs to be merged are placed in the initial BBU group, where an initial BBU group corresponds to one Figure 1 The BBU chassis in the

[0100] Step 333: Determine the maximum total number of savable baseband boards according to the initial number of savable baseband boards corresponding to all the initial BBU groups after merging.

[0101] In one embodiment of the present invention, the sum of the initial numbers of saveable baseband boards corresponding to all the initial BBU groups obtained after merging is determined as the maximum total number of saveable baseband boards.

[0102] In yet another embodiment of the present invention, the maximum number of baseband boards that can be saved can also be determined according to the following formula:

[0103]

[0104]

[0105] Where n is the number of BBUs to be merged; i is the identifier of the BBU to be merged; j is the identifier of the configured baseband board in BBU i; the number of configured carrier frequencies of BBU i is o, the number of configured baseband boards of BBU i is m, the number of carrier frequencies supported by the configured baseband board j is p, the maximum number of baseband boards supported by BBU i is M, the maximum number of baseband boards that can be saved for each initial BBU group is r, and the BBU merge sequence obtained after merging is X. s is the model of the configured baseband board, P s Represents the number of carrier frequencies supported by the baseband board model; P i，j Refers to the number of carrier frequencies supported by baseband board j in BBU i. k refers to an initial BBU group after merging; N is the number of initial BBU groups after merging.

[0106] In the restriction condition, x i ∈{0,1} indicates whether to merge BBU i into the initial BBU group k, 1 for merging and 0 for not merging; Indicates that the total number of baseband boards in each initial BBU group during merging does not exceed the maximum number of baseband boards supported by the chassis where the initial BBU group is located; Indicates the number of redundant carrier frequencies of the initial BBU group during merging; represents the maximum number of basebands that can be saved in an initial BBU group; where s∈P i The baseband board model belongs to the baseband board model in BBU i.

[0107] Step 104: Taking the maximum total number of baseband boards that can be saved as the optimization target, iteratively optimize the initial BBU merging sequence to obtain a target BBU merging sequence.

[0108] In one embodiment of the present invention, a random optimization method can be used when iteratively optimizing the initial BBU merging sequence, that is, the initial BBU merging sequence is shuffled or other perturbation operations are performed, a new BBU merging sequence is randomly generated as a new solution to be verified, and the maximum number of baseband boards that can be saved by the new solution is calculated according to the above steps, and the optimal solution is updated each time according to the maximum number of baseband boards that can be saved by the new solution. Repeat the above operations of generating a new solution, verifying the new solution, and updating the optimal solution until a preset termination condition is met, wherein the termination condition can be reaching a preset number of iterations, having traversed all possible solutions, or the optimal solution no longer changes. The specific random optimization process can be completed using a simulated annealing algorithm.

[0109] In one embodiment of the present invention, step 104 further includes:

[0110] Step 1041: Determine the maximum total number of baseband boards that can be saved in the initial BBU merging sequence as the target maximum total number of baseband boards that can be saved.

[0111] The randomly generated initial BBU merging sequence is used as the initial optimal solution.

[0112] Step 1042: Perform disturbance processing on the initial BBU combined sequence to obtain a disturbed BBU combined sequence.

[0113] In one embodiment of the present invention, as described above, the perturbation processing is to obtain a new solution to be verified. Since the maximum total number of baseband boards that can be saved is only related to the positions of each BBU in the BBU merging sequence, the perturbation processing can be to randomly change at least two BBUs to be merged in any multiple initial BBU groups in the initial BBU merging sequence.

[0114] For example, the initial BBU merging sequence (1, 2, 3), (4, 5, 6) is disturbed, and the generated disturbed BBU merging sequence may be (1, 3, 4), (2, 5, 6) or (1, 2), (3, 4, 5, 6).

[0115] In still another embodiment of the present invention, step 1042 further includes 421: exchanging positions of at least two of the BBUs to be merged in the initial BBU merge sequence to obtain the disturbed BBU merge sequence; the at least two BBUs to be merged are respectively located in different initial BBU groups.

[0116] Step 1043: Determine the maximum total number of baseband boards that can be saved after iterations corresponding to the disturbance BBU merging sequence according to the configured baseband board information and the configured carrier frequency information.

[0117] In one embodiment of the present invention, the calculation process of the maximum number of baseband boards that can be saved after iteration can refer to the aforementioned step 102 and will not be repeated here.

[0118] Step 1044: Update the target maximum total number of baseband boards that can be saved according to the maximum total number of baseband boards that can be saved after the iteration.

[0119] In one embodiment of the present invention, the maximum total number of baseband boards that can be saved after iteration is compared with the target maximum total number of baseband boards that can be saved, and the larger value of the two is determined as the updated target maximum total number of baseband boards that can be saved.

[0120] Step 1045: After the target maximum total number of baseband boards that can be saved is updated, return to the perturbation process for the initial BBU merging sequence and repeat the process until a preset termination condition is met.

[0121] In one embodiment of the present invention, the initial BBU merging sequence is iteratively disturbed, and the target maximum total number of baseband boards that can be saved is iteratively updated according to the verification result of the solution after each disturbance until a preset number of iterations is reached, all possible solutions have been traversed, or the optimal solution no longer changes.

[0122] Step 1046: Determine the disturbance BBU merging sequence or the initial BBU merging sequence corresponding to the updated target maximum total number of baseband boards that can be saved as the target BBU merging sequence.

[0123] In one embodiment of the present invention, for the six BBUs to be merged shown in the above Table 1, the target BBU merging sequence obtained according to the above steps can be (1, 3, 5), (2, 4, 6) or (1, 5, 6), (2, 3, 4), and the maximum total number of baseband boards that can be saved in both cases is 3.

[0124] Step 105: Merge the BBUs to be merged according to the target BBU merging sequence.

[0125] In one embodiment of the present invention, the target BBU merging sequence can be sent to the BBU planning or management personnel, so that they can merge and adjust the baseband boards and other components in the BBU to be merged according to the target BBU merging sequence, so as to achieve the purpose of saving the most baseband boards.

[0126] The embodiment of the present invention obtains configured baseband board information, configured carrier frequency information and maximum supported baseband board information respectively corresponding to multiple BBUs to be merged, merges the BBUs to be merged according to the maximum supported baseband board information and the configured baseband board information, and obtains an initial BBU merge sequence; the initial BBU merge sequence includes at least one initial BBU group, and the initial BBU group includes at least one BBU to be merged, determines the maximum total number of baseband boards that can be saved in the initial BBU merge sequence according to the configured baseband board information and the configured carrier frequency information, and iteratively optimizes the initial BBU merge sequence with the maximum total number of baseband boards that can be saved as the optimization goal. A target BBU merging sequence is obtained, and the BBUs to be merged are merged according to the target BBU merging sequence, which is different from the solution used in the prior art of manually sorting the base station BBUs in the computer room according to the number of redundant carrier frequencies from large to small, and judging in turn whether the BBUs meet the merging restriction conditions and whether the baseband boards can be reduced. However, the number of reduced baseband boards cannot reach the maximum, so the BBU merging efficiency and accuracy are low. The embodiment of the present invention iteratively optimizes the initial BBU sequence by taking the maximum number of baseband boards that can be saved as the optimization goal, and can automatically output the target BBU merging sequence that saves the maximum number of baseband boards, thereby improving the efficiency and accuracy of BBU merging.
