In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for implementing allocation of a radio carrier frequency resource pool according to an embodiment of the present invention. The method comprises the following steps:
in step 110, carrier frequency configuration information of the base station is acquired. For example, as shown in table 1, the relationship between the existing carrier frequency and the radio frequency board, the channel board, and the carrier frequency resource pool can be queried through the network management command.
TABLE 1 relationship of carrier frequency to radio frequency board, channel board, carrier frequency resource pool
In step 120, the number of carrier frequencies having the same cell number and the same carrier sequence number is obtained according to the configuration information. For example, according to the data in table 1, the cell numbers and carrier frequencies are sorted into table 2, and the newly added carrier frequencies are added into the table, where x1-x10 in table 2 are the number of the same carrier frequencies of the same cell number, and the value range is 0-3.
| Cell number/carrier sequence | 6 | 7 | 5 | 4 | 8 |
| Base station number | x1 | x2 | x3 | x4 | x5 |
| Base station number +2000 | x6 | x7 | x8 | x9 | x10 |
TABLE 2 number of carrier frequencies of same cell number and same carrier sequence number
In step 130, the carrier frequencies are combined based on the allocation rule and the number of carrier frequencies, so as to reallocate different carrier frequencies to the carrier frequency resource pool.
In the relocation of wireless network resources, the allocation rules include dependency and constraint relationships among the radio frequency board, the channel board, the carrier frequency, and the resource pool. The dependency relationship is shown in fig. 2:
(1) the carrier frequency is carried on the radio frequency board.
(2) The carrier frequency must bind to the pool of carrier frequency resources.
(3) The pool of carrier frequency resources must be carried on the channel board.
(4) The channel board processes the front backchannel data.
The constraint relationship comprises:
(1) one channel board is independent into one carrier frequency resource pool. That is, only one channel board is in one carrier frequency resource pool, and the DO channel boards can only be separately made into pools.
(2) One carrier frequency resource pool binds N carrier frequencies at most. For example, in C-network, the channel board can support 6 carriers at maximum due to the processing capacity of the carrier frequency resource pool.
(3) The same cell number and the same carrier frequency number must be bound in the same carrier frequency resource pool.
(4) The radio frequency board bound with the carrier frequency and the channel board bound with the carrier frequency have transparent transmission relation.
(5) As shown in fig. 3, the channel boards 0, 1, 2, and 3 can be transmitted through, and the channel boards 2, 3, 4, and 5 can be transmitted through.
For example, several combinations of the numbers x1-x10 in table 2 can be obtained according to three conditions, i.e., "one channel board is independent into one carrier frequency resource pool", "the same carrier frequency number of the same cell number must be bound in the same carrier frequency resource pool", and "at most 6 carrier frequencies are bound in one carrier frequency resource pool", in the dependency relationship and constraint relationship existing among the radio frequency board, the channel board, the carrier frequency, the resource pool. For example, any 1-6 numbers are combined into one group, and the sum of the numbers in each group is less than or equal to 6. In addition, since any value in table 2 can be put into one carrier frequency resource pool, but there are not so many carrier frequency resource pools, these values are combined to form several groups, and the number of the carrier frequency resource pools is equal to the number of the groups, so that the carrier frequency in each group is put into the appropriate carrier frequency resource pool.
In the embodiment, carrier frequency configuration information of a base station is acquired; acquiring the number of carrier frequencies with the same cell number and the same carrier serial number according to the configuration information; and combining the carrier frequencies based on the allocation rule and the number of the carrier frequencies so as to reallocate different carrier frequencies to the carrier frequency resource pool. The invention can quickly obtain the optimal carrier frequency resource pool recombination scheme through the allocation rule, so that the utilization rate of the existing network resources can be maximized. In addition, when network resources are relocated, the software and hardware resource configuration cannot be matched at will and is limited by association constraints, and software and hardware reconfiguration needs to be performed on the premise that the software and hardware association constraint conditions are met according to the current situation of the software and hardware configuration. The algorithm is simple, only needs second level for automatic realization, and is used for one time of development. Because the realization difference between different manufacturers is not large, the method can be popularized only by slightly modifying.
Fig. 4 is a flowchart illustrating a method for allocating a radio carrier frequency resource pool according to another embodiment of the present invention. The method comprises the following steps:
in step 410, carrier frequency configuration information of the base station is acquired. For example, as shown in table 1, the relationship between the existing carrier frequency and the radio frequency board, the channel board, and the carrier frequency resource pool can be queried through the network management command.
In step 420, the number of the slot position numbers of the same cell number, the same channel board connected to the radio frequency board and the carrier frequency number of the same carrier serial number are obtained according to the configuration information. For example, according to the data in table 1, the cell number, the slot number on the rf board, and the cell number are rearranged into table 3. According to the slot number of the same cell number _ rf board, the number of different carrier frequencies (x1-x60) is counted according to the "slot number _ carrier sequence of the same cell number _ rf board", so as to generate table 3, and the newly expanded cell number _ carrier sequence is added to the table. That is, a dimensional constraint relationship is added on the basis of table 2, for example, a transparent transmission relationship exists between a radio frequency board bound with a carrier frequency and a channel board bound with a carrier frequency, which may be referred to as row constraint.
TABLE 3 number of carrier frequencies of same cell number, slot number of same channel board linked to radio frequency board and same carrier serial number
At step 430, the carrier frequencies are combined based on the allocation rules and the number of carrier frequencies to reallocate different carrier frequencies to the pool of carrier frequency resources.
For example, for the numbers in table 3, combining requires the following conditions to be satisfied: the numbers of any grid are combined to form a group; the number of groups must equal the number of carrier frequency resource pools; the cell number is equal to the base station number, and the carrier frequencies with the same cell number and the same carrier sequence number are in the same carrier frequency resource pool; the cell number is equal to +2000 of the base station number, and the carrier frequencies with the same cell number and the same carrier sequence number also need to be in the same carrier frequency resource pool; the carrier sequences of different lattices can be in the same carrier frequency resource pool; each row must satisfy a row constraint. The carrier frequencies in each group can be put into an appropriate carrier frequency resource pool through the conditions.
In the embodiment, by analyzing the association and constraint relationship between software resources (carrier frequency, resource pool) and hardware resources (channel board, carrier frequency board), the optimal carrier frequency resource pool recombination scheme is rapidly obtained, so that the utilization rate of the existing network resources can be maximized.
Fig. 5 is a flowchart illustrating a process of determining a carrier frequency resource pool according to the present invention. The method comprises the following steps:
in step 510, it is determined whether the total number of carrier frequencies of the base station DO is less than a threshold, for example, it is determined whether the total number of carrier frequencies of the base station DO is less than 6, if the total number of carrier frequencies of the base station DO is less than the threshold, step 520 is executed, otherwise, step 521 is executed.
For example, if the sector of base station number 49 9 is expanded to 78 frequency points, it is first determined whether the total number of DO carrier frequencies with BTSID of 49 is less than 6. Because one carrier frequency resource pool binds 6 carrier frequencies at most, but each base station has at least one carrier frequency resource pool, if the total carrier frequency of the base station is less than 6, the capacity can be directly expanded without considering the following complicated rules.
In step 520, the capacity of the carrier frequency resource pool is directly expanded.
In step 521, it is determined whether the number of the carrier frequency resource pool is greater than the base station DO carrier frequency divided by 6 rounded up. If so, go to step 530, otherwise go to step 531.
For example, the BTS DO carrier frequency number X is 7+1 is 8, the carrier frequency resource pool number Y is 2, and it is determined that Y > [ X/6] is rounded up.
In step 530, the pool number of carrier frequency resources where the cell number-carrier sequence number is located is determined. For example, the carrier frequency resource pool number N-2 is determined.
At step 531, a "base station hardware is not sufficient" prompt may be returned.
In step 540, it is determined whether the number of carrier frequencies in the carrier frequency resource pool is smaller than a threshold, for example, whether the number of carrier frequencies in the carrier frequency resource pool is smaller than 6, if the number of carrier frequencies in the carrier frequency resource pool is smaller than the threshold, step 550 is executed, otherwise, step 560 is executed.
In step 550, the capacity of the carrier frequency resource pool is directly expanded.
In step 560, it is determined whether both the RRU and the RFU are connected to the slot of the predetermined channel board, if so, step 570 is performed, otherwise, step 580 is performed.
For example, as shown in fig. 3, the transparent transmission relationship exists between the radio frequency board bound with the carrier frequency and the channel board bound with the carrier frequency, the transparent transmission between channel boards 0, 1, 2, and 3 can be performed, and the transparent transmission between channel boards 2, 3, 4, and 5 can be performed. That is, if both RRU and RFU are connected to the slot of channel boards No. 2 and No. 3, the row constraint condition is not considered when the carrier frequency resource pool is reconfigured, i.e., the transparent transmission relationship between the radio frequency board bound to the carrier frequency and the channel board bound to the carrier frequency is not considered.
In step 570, the carrier frequency resource pool is reassembled without considering the row constraint condition, and the specific implementation steps are shown in fig. 6.
In step 580, the carrier frequency resource pool reorganization is performed in consideration of the row constraint condition, and the specific implementation steps are as shown in fig. 7.
In fig. 6, the resource pool reorganization of carrier frequencies without considering the row constraint condition includes the following steps:
in step 610, carrier frequency configuration information of the base station is obtained, and on the basis of generating table 1, the newly expanded cell number-carrier sequence is loaded into the table.
In step 620, the number of carrier frequencies with the same cell number and the same carrier sequence number is obtained according to the configuration information.
In step 630, the carrier frequencies are recombined using the constraint condition according to the number of the carrier frequencies, for example, any 1-6 numbers can be combined into a group, the number of the group must be equal to the number of the resource pool of the carrier frequencies, and it is ensured that the sum of the numbers of the groups is less than or equal to 6. For example, the numbers x1-x10 in table 2 are 3, 2, 1, 0, respectively. According to the above constraint, for example, the carrier frequency resource pool is 3, the first group is x1, x2 and x7, the second group is x3, x6, x8 and x9, and the third group is x4, x5 and x 10. That is, a carrier frequency whose cell number is 662 carrier serial number of 6, a carrier frequency whose cell number is 662 carrier serial number of 7, and a carrier frequency whose cell number is 2662 carrier serial number of 7 are grouped, a carrier frequency whose cell number is 662 carrier serial number of 5, a carrier frequency whose cell number is 2662 carrier serial number of 6, a carrier frequency whose cell number is 2662 carrier serial number of 5, and a carrier frequency whose cell number is 2662 carrier serial number of 4 are grouped, a carrier frequency whose cell number is 662 carrier serial number of 4, a carrier frequency whose cell number is 662 carrier serial number of 8, and a carrier frequency whose cell number is 2662 carrier serial number of 8. It should be understood by those skilled in the art that the above-described allocation methods are merely exemplary representations, and different combinations are possible according to specific situations, for example, according to the number of frequency points that need to be expanded.
In one embodiment, the optimal combination may also be selected to reassemble the pool of carrier frequency resources. For example, for the numbers x1-x10 in table 2, x1 and x3 may be used as the first group, x2, x6, x8 and x9 may be used as the second group, and x4, x5, x7 and x10 may be used as the third group. And summing the carrier frequency telephone traffic of each group in the combination, then performing weighting calculation, and judging the difference between the telephone traffic of the groups. For example, the first group is x1, x2 and x7, the second group is x3, x6, x8 and x9, and the third group is the combination of x4, x5 and x10, wherein the traffic volume difference between the groups is minimum, and the combination is judged to be the optimal combination.
In step 640, the carrier frequencies in the above combinations are sequentially placed in the corresponding carrier frequency resource pools to obtain the carrier frequency resource pool numbers corresponding to the cell number-carrier sequence number.
In step 650, according to the carrier frequency resource pool number corresponding to the cell number-carrier serial number, fill the newly allocated carrier frequency resource pool number into table 1, and record the carrier frequency resource pool number allocated to the newly expanded sector frequency point.
Fig. 7 shows that the carrier frequency resource pool reorganization considering the row constraint condition includes the following steps:
in step 710, carrier frequency configuration information of the base station is obtained, and a corresponding relationship between the carrier frequency bound on each radio frequency board card and the slot on the board card is obtained.
In step 720, the slot position numbers of the same cell number, the radio frequency board uplink same channel board and the carrier frequency number of the same carrier serial number are obtained according to the configuration information. For example, according to the data in table 1, the cell number, the slot number on the rf board, and the cell number are rearranged into table 3.
In step 730, the slot number of the row constraint condition is replaced with the carrier frequency resource pool number according to the binding relationship between the channel board and the carrier frequency resource pool.
At step 740, carrier frequencies are recombined using constraints according to the number of carrier frequencies, as shown in table 3, x1-x60 are recombined, where the numbers of any lattice are combined into one group; the number of groups must equal the number of carrier frequency resource pools; the cell number is equal to the base station number, and the carrier frequencies with the same cell number and the same carrier sequence number are in the same carrier frequency resource pool; the cell number is equal to +2000 of the base station number, and the carrier frequencies with the same cell number and the same carrier sequence number also need to be in the same carrier frequency resource pool; the carrier sequences of different lattices can be in the same carrier frequency resource pool; each row must satisfy a row constraint.
In step 750, it is determined whether the program has a solution, if so, step 760 is performed, otherwise, step 761 is performed.
The algorithms are not necessarily all solved, if the computer is not calculated, the problem needs to be solved by adjusting the board card slot position of the radio frequency board upper link through manual work, and considering that the problem is a full-automatic calculation process, the processing is prompted by judging sentences for the part needing manual operation.
In step 760, the combination above is used to obtain the cell number-carrier sequence number corresponding to the carrier frequency resource pool number.
At step 761, a prompt is returned to adjust the card port.
In step 770, according to the carrier frequency resource pool number corresponding to the cell number-carrier sequence number, fill the newly allocated carrier frequency resource pool number into table 1, and record the carrier frequency resource pool number allocated to the newly expanded sector frequency point.
In the embodiment of the invention, the optimal carrier frequency resource pool recombination scheme is quickly obtained by analyzing the association and constraint relation between software resources (carrier frequencies and resource pools) and hardware resources (channel boards and carrier frequency boards), so that the utilization rate of the existing network resources can be maximized.
In addition, the traditional association constraint condition is mapped into the calculation of the table number, so that the computer is very easy to realize, and the system has the following advantages: the association constraint conditions among the complex carrier frequency resource pools are solved, the algorithm program is simple to realize, and the operation efficiency is high; the later operation does not need labor cost, is completely automatically completed by the system, and has strong timeliness and low cost; the copy popularization is strong, and the copy network can be applied to different local networks for use by slight modification.
Fig. 8 is a schematic structural diagram of a system for implementing allocation of radio carrier frequency resource pools according to an embodiment of the present invention. The system comprises a configuration information acquisition unit 810, a carrier frequency quantity determination unit 820 and a resource pool recombination unit 830, wherein:
the configuration information obtaining unit 810 is configured to obtain carrier frequency configuration information of a base station. For example, as shown in table 1, the relationship between the existing carrier frequency and the radio frequency board, the channel board, and the carrier frequency resource pool can be queried through the network management command.
The carrier frequency number determination unit 820 is configured to obtain the number of carrier frequencies having the same cell number and the same carrier sequence number according to the configuration information. For example, according to the data in table 1, the cell numbers and carrier frequencies are sorted into table 2, and the newly added carrier frequencies are added into the table, where x1-x10 in table 2 are the number of the same carrier frequencies of the same cell number, and the value range is 0-3.
The resource pool reassembling unit 830 is configured to combine the carrier frequencies based on the allocation rule and the number of carrier frequencies, so as to reallocate different carrier frequencies to the carrier frequency resource pool.
In the relocation of wireless network resources, the allocation rules include dependency and constraint relationships among the radio frequency board, the channel board, the carrier frequency, and the resource pool. The dependency relationship is shown in fig. 2:
(1) the carrier frequency is carried on the radio frequency board.
(2) The carrier frequency must bind to the pool of carrier frequency resources.
(3) The pool of carrier frequency resources must be carried on the channel board.
(4) The channel board processes the front backchannel data.
The constraint relationship comprises:
(1) one channel board is independent into one carrier frequency resource pool. That is, only one channel board is in one carrier frequency resource pool, and the DO channel boards can only be separately made into pools.
(2) One carrier frequency resource pool binds N carrier frequencies at most. For example, in C-network, the channel board can support 6 carriers at maximum due to the processing capacity of the carrier frequency resource pool.
(3) The same cell number and the same carrier frequency number must be bound in the same carrier frequency resource pool.
(4) The radio frequency board bound with the carrier frequency and the channel board bound with the carrier frequency have transparent transmission relation.
(5) As shown in fig. 3, the channel boards 0, 1, 2, and 3 can be transmitted through, and the channel boards 2, 3, 4, and 5 can be transmitted through.

The invention can quickly obtain the optimal carrier frequency resource pool recombination scheme through the allocation rule, so that the utilization rate of the existing network resources can be maximized. In addition, when network resources are relocated, the software and hardware resource configuration cannot be matched at will and is limited by association constraints, and software and hardware reconfiguration needs to be performed on the premise that the software and hardware association constraint conditions are met according to the current situation of the software and hardware configuration. The algorithm is automatically realized only in the second level, and is developed once for all. The implementation is not very different among different manufacturers, so the method can be applied only by slight modification.
In another embodiment of the present invention, the configuration information obtaining unit 810 is configured to obtain carrier frequency configuration information of a base station. For example, as shown in table 1, the relationship between the existing carrier frequency and the radio frequency board, the channel board, and the carrier frequency resource pool can be queried through the network management command.
The carrier frequency number determining unit 820 is configured to obtain the number of carrier frequencies having the same cell number, slot number of the radio frequency board connected to the same channel board, and the same carrier sequence number according to the configuration information. For example, according to the data in table 1, the cell number, the slot number on the rf board, and the cell number are rearranged into table 3. According to the slot number of the same cell number _ rf board, the number of different carrier frequencies (x1-x60) is counted according to the "slot number _ carrier sequence of the same cell number _ rf board", so as to generate table 3, and the newly expanded cell number _ carrier sequence is added to the table.
The resource pool reassembling unit 830 is configured to combine the carrier frequencies based on the allocation rule and the number of carrier frequencies, so as to reallocate different carrier frequencies to the carrier frequency resource pool.
For example, for the numbers in table 3, combining requires the following conditions to be satisfied: the numbers of any grid are combined to form a group; the number of groups must equal the number of carrier frequency resource pools; the cell number is equal to the base station number, and the carrier frequencies with the same cell number and the same carrier sequence number are in the same carrier frequency resource pool; the cell number is equal to +2000 of the base station number, and the carrier frequencies with the same cell number and the same carrier sequence number also need to be in the same carrier frequency resource pool; the carrier sequences of different lattices can be in the same carrier frequency resource pool; each row must satisfy a row constraint. The carrier frequencies in each group can be put into an appropriate carrier frequency resource pool through the conditions.
In the embodiment, by analyzing the association and constraint relationship between software resources (carrier frequency, resource pool) and hardware resources (channel board, carrier frequency board), the optimal carrier frequency resource pool recombination scheme is rapidly obtained, so that the utilization rate of the existing network resources can be maximized.
In another embodiment of the present invention, a slot position determining unit 840 may be further included, where the slot position determining unit 840 is configured to determine whether the RRU and the RFU are connected to a slot position of a predetermined channel board. For example, as shown in fig. 3, the transparent transmission relationship exists between the radio frequency board bound with the carrier frequency and the channel board bound with the carrier frequency, the transparent transmission between channel boards 0, 1, 2, and 3 can be performed, and the transparent transmission between channel boards 2, 3, 4, and 5 can be performed. That is, if both RRU and RFU are connected to the slot of channel boards No. 2 and No. 3, the row constraint condition is not considered when the carrier frequency resource pool is reconfigured, i.e., the transparent transmission relationship between the radio frequency board bound to the carrier frequency and the channel board bound to the carrier frequency is not considered.
In another embodiment of the present invention, the present invention may further include a total carrier frequency determining unit 850, where the total carrier frequency determining unit 850 is configured to determine whether the total carrier frequency number of the base station DO is smaller than a threshold and determine whether the number of the carrier frequency resource pools is greater than a number obtained by dividing the base station DO carrier frequency number by 6, for example, the threshold is 6, and since one carrier frequency resource pool binds 6 carrier frequencies at most, but each base station has at least one carrier frequency resource pool, if the total carrier frequency number of the base station is smaller than 6, the capacity can be directly expanded without considering the following complicated rules. If the number of the carrier frequency resource pool is less than the integer of the DO carrier frequency divided by 6, the hardware is added, and the computer can prompt the hardware.
The total carrier frequency number determining unit 850 is further configured to determine whether the number of carrier frequencies in the carrier frequency resource pool in which the same carrier sequence number of the same cell number is located is less than a threshold, for example, is less than 6. If the number of the RRU is not less than 6, the slot position determining unit 840 is required to determine whether the RRU and the RFU are connected to the slot position of the predetermined channel board.
In the embodiment of the invention, the optimal carrier frequency resource pool recombination scheme is quickly obtained by analyzing the association and constraint relation between software resources (carrier frequencies and resource pools) and hardware resources (channel boards and carrier frequency boards), so that the utilization rate of the existing network resources can be maximized. In application, the busy and idle characteristics of different network elements are deeply analyzed by butting the performance, configuration and basic information, the characteristics of geographical distribution, busy hour distribution, optical fiber routing and the like of the network elements with lower resource utilization rate are known, reasonable resource sharing is carried out, and various saved network resources are timely adjusted to more required areas, so that the network operation cost and the maintenance cost are reduced to the maximum extent.
