Among them, 2G is typically a Global System for mobile Communications (GSM), 3G is typically a Wideband Code Division Multiple Access (WCDMA) mobile communication System, and 4G is typically a Long Term Evolution (LTE).
The GSM spectrum resource is allocated in units of 200K bandwidth, such a unit is called a frequency point (Arfcn), and a cell allocates and uses a part of available frequency points. LTE employs Orthogonal Frequency Division Multiplexing (OFDM) technology, and its carrier is expressed by a center Frequency point and a bandwidth, and LTE standard bandwidths specified by the third generation partnership project (3GPP) include several types, such as 1.4 mhz, 3 mhz, 5 mhz, 10 mhz, 15 mhz, and 20 mhz, and multiple cells of LTE often use the same center Frequency and bandwidth.
The combined use of GSM and LTE is a networking mode often used by operators, GSM is mainly used for providing voice services, LTE is mainly used for providing high-speed data services, and the GSM and LTE can be well complemented. GSM and LTE have the same operating band, for example, the 1800 mega band is often used for both GSM and LTE, and therefore, it is necessary to study how to efficiently allocate and use spectrum resources in such a case.

In the first embodiment of the present invention, before executing the step S101, a determination period for performing spectrum resource allocation, information of a spectrum resource sharing area, and a first time map of a first mobile communication system in the spectrum resource sharing area, where the first mobile communication system is suitable for releasing spectrum resources, need to be obtained. The determination period may be set by a user according to experience, for example, 15 minutes, and the information of the spectrum resource sharing area may be configured by the user on a network configuration optimization device (CSON) and sent to the base station controller of the first mobile communication system by the CSON, where the spectrum resource sharing area is an area formed by a plurality of first cells and a plurality of second cells of the second mobile communication system within a certain geographic range. In addition, the first time chart can clearly indicate in which time periods the first mobile communication system (for example, the GSM system) is suitable for releasing the spectrum resources, and can indicate how many spectrum resources can be released at most in the time periods suitable for releasing the spectrum resources. The manner in which the first time bitmap is specifically obtained will be described in detail later.
Step S102, judging whether the spectrum resource sharing area meets the condition of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system according to the channel resource occupation condition.
In the first embodiment of the present invention, the second mobile communication system may be an LTE system, and is not limited to the LTE system, and may also be another mobile communication system.
Step S103, when the spectrum resource sharing area meets the condition of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, adjusting the spectrum resources of the first mobile communication system and the second mobile communication system.
Before or after the adjustment, the spectrum resources occupied by the second mobile communication system are in the middle, and the spectrum resources occupied by the first mobile communication system are on two sides of the spectrum resources of the second mobile communication system. Therefore, the frequency spectrum resources of the first mobile communication system and the second mobile communication system can be adjusted more conveniently. If the first mobile communication system is a GSM system and the second mobile communication system is an LTE system, when adjusting spectrum resources of the GSM system and the LTE system, it is not necessary to adjust a center frequency point of the LTE system, so that a neighbor relation is not required to be modified.
In the first embodiment of the present invention, whether the spectrum resource sharing region meets the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system is determined according to the channel resource occupation condition of the first cell of the first mobile communication system in the first preset time period before the current time, and when the spectrum resource sharing region meets the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, the spectrum resources of the first mobile communication system and the second mobile communication system are adjusted, so that the problem that the spectrum resources cannot be allocated and used sufficiently and intelligently and negative influences are brought to network performance is solved, and the effects of allocating and using the spectrum resources sufficiently, intelligently and accurately and improving the comprehensive performance of the network are achieved.
Further, in the first embodiment of the present invention, the step S101 may specifically include the following steps: when the judgment period for allocating the spectrum resources arrives,
and judging whether the first mobile communication system can release the frequency spectrum resources in the current time period or not according to the first time bitmap, and acquiring the channel resource occupation condition of the first cell in a first preset time period before the current time when the first mobile communication system can release the frequency spectrum resources in the current time period.
In the first embodiment of the present invention, there are two ways to obtain the first time bitmap. The first one is: the first time bitmap sent by the CSON can be received by the GSM network manager. The second method is as follows: the BSC generates a first time bitmap, and specifically, first obtains first service load data of a first cell in the spectrum resource sharing region in a historical time period corresponding to each second preset time period (each second preset time period is different from each other), so as to facilitate estimation of the service load data in each second preset time period in the future. Taking a second preset time period as an example, judging whether the service load data of the first cell in the future second preset time period exceeds a specific threshold value, if so, considering that the first cell is not suitable for releasing the spectrum resources in the future second preset time period, if not, considering that the first cell is suitable for releasing the spectrum resources in the future second preset time period, after finishing the judgment on each first cell in the area where the spectrum resources are collinear, counting whether the number of the first cells in the area where the spectrum resources are collinear and suitable for releasing the spectrum resources in the future second preset time period reaches a specific number, if so, considering that the first mobile communication system is suitable for releasing the spectrum resources in the future second preset time period, and if not, the first mobile communication system is considered to be unsuitable for releasing the frequency spectrum resources in a second preset time period in the future. Meanwhile, if the first mobile communication system is suitable for releasing the frequency spectrum resources in the second preset time period in the future, the frequency spectrum resources which can be released by the first mobile communication system most in the second preset time period in the future can be obtained further according to the condition of the service load data of each first cell after the first mobile communication system releases different frequency spectrum resources in the second preset time period in the future. According to the method, whether the first mobile communication system is suitable for releasing the frequency spectrum resources in each second preset time period in the future is judged, and then the first time bitmap is generated. And the generated first time bitmap can directly indicate the frequency spectrum resources which can be released at most in each time period suitable for releasing the frequency spectrum resources of the first mobile communication system. For example, when it is evaluated whether the first mobile communication system (e.g., GSM system) of monday is suitable for releasing the spectrum resource in 9: 00-10: 00 (i.e., the second preset time period), it may be evaluated whether the first mobile communication system (e.g., GSM system) of monday is suitable for releasing the spectrum resource in 9: 00-10: 00 by using the first service load data of 9: 00-10: 00 every monday of the previous weeks. By analogy, whether the first mobile communication system (for example, a GSM system) is suitable for releasing the spectrum resources in each of a plurality of second preset time periods different from each other can be evaluated in this way. It should be further noted that the granularity of the first time bitmap may be hours or a shorter time period.
In the first embodiment of the present invention, the traffic load data of the first cell refers to a ratio of the number of channels occupied by the first cell to the number of channels available to the first cell. Therefore, the first service load data, the second service load data, the third service load data, the fourth service load data, the fifth service load data and the sixth service load data in the embodiment of the present invention all mean this.
Further, in the first embodiment of the present invention, the step S102 may specifically include the following steps:
the method comprises the steps of firstly, judging whether the current frequency spectrum resource of a second mobile communication system in a frequency spectrum resource sharing area reaches a preset frequency spectrum resource threshold, directly determining that the frequency spectrum resource sharing area does not meet the condition for adjusting the frequency spectrum resources of a first mobile communication system and a second mobile communication system when the current frequency spectrum resource of the second mobile communication system in the frequency spectrum resource sharing area reaches the preset frequency spectrum resource threshold, and judging whether second service load data of a first cell is below a preset release load threshold after the first cell releases the first frequency spectrum resource according to the channel resource occupation condition of the first cell of the first mobile communication system when the current frequency spectrum resource of the second mobile communication system in the frequency spectrum resource sharing area does not reach the preset frequency spectrum resource threshold. When second service load data of the first cell is below a preset release load threshold, determining that the first cell can release first spectrum resources; when the second service load data of the first cell is above a preset release load threshold, determining that the first cell can not release the first spectrum resource; and after judging whether each first cell of the first mobile communication system in the spectrum resource sharing area can release the first spectrum resource or not, continuously executing the second step.
And secondly, counting the number of first cells of the first mobile communication system which can not release the first spectrum resources in the spectrum resource sharing area, and judging whether the number of the first cells of the first mobile communication system which can not release the first spectrum resources is smaller than a first preset value (the first preset value can be set by a user according to experience). When the number of first cells of a first mobile communication system which can not release first spectrum resources is smaller than a first preset value, determining that a spectrum resource sharing area meets the condition of adjusting the spectrum resources of the first mobile communication system and a second mobile communication system; and when the number of the first cells of the first mobile communication system which can not release the first frequency spectrum resources is larger than or equal to a first preset value, determining that the frequency spectrum resource sharing area does not meet the condition of adjusting the frequency spectrum resources of the first mobile communication system and the second mobile communication system.
It should be noted that, by determining whether the spectrum resource sharing area satisfies the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system in this way, it can be accurately determined whether the first mobile communication system is currently suitable for releasing the spectrum resources to the second mobile communication system, so as to avoid the situation that the spectrum resources are not reasonably utilized due to the release of the spectrum resources of the first mobile communication system to the second mobile communication system when the first mobile communication system is not suitable for releasing the spectrum resources.
Further, in the first embodiment of the present invention, the step S103 may specifically include the following steps:
the method comprises the following steps that first frequency spectrum resources of a first mobile communication system (such as a GSM system) are released, and an instruction for expanding the first frequency spectrum resources into frequency spectrum resources of a second mobile communication system is sent to a base station of the second mobile communication system (such as an LTE system);
when the judgment period is reached again, continuously judging whether the spectrum resource sharing area meets the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system until the spectrum resource sharing area does not meet the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, wherein when the spectrum resource sharing area is judged to meet the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, releasing the second spectrum resource of the first mobile communication system, and sending an instruction for expanding the second spectrum resource into the spectrum resource of the second mobile communication system to a base station of the second mobile communication system; and when the spectrum resource sharing region does not meet the condition of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, judging whether the first mobile communication system needs to recover the released spectrum resources, and when the first mobile communication system needs to recover the released spectrum resources, sending an instruction for releasing the third spectrum resources to the base station of the second mobile communication system, and allocating the third spectrum resources to the first mobile communication system.
The step of circularly determining whether the spectrum resource sharing area satisfies the condition of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system each time the determination period is reached is similar to the step specifically included in step S102, and therefore, the detailed description thereof is omitted here.
It should be noted that, in the two steps of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, when the spectrum resource sharing area meets the condition of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, the first mobile communication system may release a part of the spectrum resources to the second mobile communication system, in this process, in order to ensure the stability of the network and the smoothness of the service, the second mobile communication system may expand the spectrum resources in stages, that is, a small part of the spectrum resources (for example, the first spectrum resources) is released to the second mobile communication system through the first mobile communication system, after the small part of the spectrum resources is released, some spectrum resources (for example, the second spectrum resources) are continuously released to the second mobile communication system, of course, under the condition that the network and the service are allowed, the first mobile communication system may also release the spectrum resource to the second mobile communication system at one time, so that the second mobile communication system may reach a preset spectrum resource threshold through one time of spectrum resource expansion (the preset spectrum resource threshold is the largest spectrum resource preset for the second mobile communication system, and of course, here, an initial spectrum resource is also preset for the second mobile communication system, and it should be noted that the preset spectrum resource threshold and the initial spectrum resource may be set according to a standard bandwidth of the second mobile communication system).
Similarly, in the process of reclaiming the released spectrum resources in the first mobile communication system, in order to ensure the stability of the network and the smoothness of the service, the released spectrum resources can also be reclaimed in stages. That is, a small portion of the released spectrum resources (e.g., the third spectrum resources) are recovered first, and then other released spectrum resources are continuously recovered. Of course, the first mobile communication system may also reclaim the released spectrum resources once when the network and the service allow. It should be further noted that, since the first mobile communication system can reclaim the released spectrum resources in stages and can reclaim the released spectrum resources at one time, the third spectrum resources in the second step should be less than or equal to the released spectrum resources of the first mobile communication system.
Further, in the first embodiment of the present invention, in the second step of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, it is required to determine whether the first mobile communication system needs to reclaim the released spectrum resources. Specifically, there are three ways to determine whether the first mobile communication system needs to reclaim the released spectrum resource.
Wherein, the first mode is as follows: acquiring third service load data of the first cell of the first mobile communication system in the spectrum resource sharing area (in order to improve the accuracy of the judgment, the third service load data should be service load data of the first cell within a period of time before the judgment time), then judging whether the third service load data exceeds a preset recovery load threshold, and when the third service load data exceeds the preset recovery load threshold, determining that the first cell needs to recover the released spectrum resources, then counting the number of the first cells needing to recover the released spectrum resources in the spectrum resource sharing area, and judging whether the number of the first cells needing to recover the released spectrum resources reaches a second preset value (the second preset value can be set by a user according to experience), wherein when the number of the first cells needing to recover the released spectrum resources reaches the second preset value, determining that a first mobile communication system needs to recover released frequency spectrum resources; and when the number of the first cells needing to recover the released spectrum resources does not reach a second preset value, determining that the first mobile communication system does not need to recover the released spectrum resources.
The second way is: acquiring fourth service load data of the first cell of the first mobile communication system (in order to improve the timeliness of judgment, the fourth service load data is the service load data of the first cell at the judgment moment), then judging whether the fourth service load data exceeds a preset emergency load threshold, when the fourth service load data exceeds the preset emergency load threshold, determining that the first cell needs to recover the released spectrum resources, then counting the number of the first cells needing to recover the released spectrum resources in the spectrum resource sharing area, and determines whether the number of first cells that need to reclaim the released spectrum resources reaches a third preset value (which can be set by the user based on experience), when the number of the first cells needing to recover the released spectrum resources reaches a third preset value, determining that the first mobile communication system needs to recover the released spectrum resources; and when the number of the first cells needing to recover the released spectrum resources does not reach a third preset value, determining that the first mobile communication system does not need to recover the released spectrum resources.
The third mode is as follows: judging according to a first time bitmap acquired before, specifically, when the first time bitmap indicates that a first mobile communication system is not suitable for releasing spectrum resources, determining that the first mobile communication system needs to recover the released spectrum resources; and when the first time bitmap indicates that the first mobile communication system is suitable for releasing the frequency spectrum resources, determining that the first mobile communication system does not need to withdraw the released frequency spectrum resources.
Here, the above-mentioned thresholds are explained, in order to effectively avoid the first mobile communication system from frequently releasing and withdrawing the spectrum resource, the preset release load threshold occurring in the first step of judging whether the spectrum resource shared region satisfies the condition of adjusting the spectrum resources of the first mobile communication system and the second mobile communication system may be set to 60% (i.e. the average occupation ratio of the channel resources is 60%), in the first way of determining whether the first mobile communication system needs to reclaim the released spectrum resources, the preset retraction loading threshold is set to 80% (i.e. the average occupied ratio of the channel resources is 80%), and in the second way of determining whether the first mobile communication system needs to retract the released spectrum resources, the preset emergency loading threshold is set to 90% (i.e. the current occupied ratio of the channel resources is 90%).
In the first embodiment of the present invention, the above allocation method is further explained by taking a standard bandwidth of 20 mega (M) as an example. Assuming that the spectrum resource sharing area is shown in fig. 2, where a solid circle represents a first cell (e.g., a GSM cell) of the first mobile communication system, a dashed circle represents a second cell (e.g., an LTE cell) of the second mobile communication system, assuming that an initial spectrum resource (i.e., an initial bandwidth) of the second mobile communication system is 5 megabytes, and a preset spectrum resource threshold (i.e., a maximum spectrum resource/bandwidth) is 15 megabytes, then an occupation situation of the spectrum resource before the second mobile communication system does not perform spectrum resource expansion is shown in fig. 3, and at this time, if the second mobile communication system performs spectrum resource expansion and expands a spectrum resource of 5 megabytes, an occupation situation of the spectrum resource after the second mobile communication system performs spectrum resource expansion is shown in fig. 4.

Fourth embodiment
As shown in fig. 6, a fourth embodiment of the present invention provides a method for allocating spectrum resources, which is applied to a network configuration optimization device (CSON), and the method specifically includes:
step S601, a first time bitmap of a first mobile communication system in a spectrum resource sharing area suitable for releasing spectrum resources is generated.
In the fourth embodiment of the present invention, before executing step S601, it is necessary to determine information of a spectrum resource sharing area according to information of an allocated spectrum resource sharing area input by a user, and send the information of the spectrum resource sharing area to a base station controller of a first mobile communication system. The spectrum resource sharing area is an area formed by a plurality of first cells and a plurality of second cells of a second mobile communication system in a certain geographic range.
Step S602, the first time bitmap is sent to a base station controller of the first mobile communication system.
In a fourth embodiment of the present invention, the first mobile communication system may be a GSM system, but is not limited to the GSM system and may also be another mobile communication system. And if the first mobile communication system is a GSM system, the base station controller of the first mobile communication system is a Base Station Controller (BSC) of the GSM. In this way, the CSON may send the first time bitmap to the BSC through the GSM network manager.
In the fourth embodiment of the present invention, the CSON is used to send the first time bitmap to the base station controller of the first mobile communication system, so that the base station controller of the first mobile communication system can obtain the channel resource occupation status of the first cell of the first mobile communication system in the first preset time period before the current time according to the first time bitmap, determine whether the spectrum resource sharing area meets the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, and adjust the spectrum resources of the first mobile communication system and the second mobile communication system when the spectrum resource sharing area meets the condition for adjusting the spectrum resources of the first mobile communication system and the second mobile communication system, thereby solving the problems that the spectrum resources cannot be fully and intelligently allocated and used, and the network performance is negatively affected, and achieving full, intelligent, and low-cost performance, Accurately distributing and using frequency spectrum resources and improving the effect of network comprehensive performance.
In the fourth embodiment of the present invention, the implementation manner of the above step S601 includes two.
The first implementation manner is as follows: and generating a first time bitmap only according to the service load data of the first cell of the first mobile communication system. Specifically, fifth service load data of the first cell of the first mobile communication system in the spectrum resource sharing area in a historical time period corresponding to each third preset time period (each third preset time period is different from each other) is obtained, and then the service load data in each third preset time period in the future can be conveniently inferred according to the obtained fifth service load data. Taking a third preset time period as an example, judging whether the service load data of the first cell in the third preset time period in the future exceeds a specific threshold value, if so, considering that the first cell is not suitable for releasing the spectrum resources in the third preset time period in the future, if not, considering that the first cell is suitable for releasing the spectrum resources in the third preset time period in the future, after finishing the judgment on each first cell in the area where the spectrum resources are collinear, counting whether the number of the first cells in the area where the spectrum resources are collinear and suitable for releasing the spectrum resources in the third preset time period in the future reaches a specific number, if the number of the first cells in the area where the spectrum resources are collinear reaches the specific number, considering that the first mobile communication system is suitable for releasing the spectrum resources in the third preset time period in the future, and if the number of the first cells in the area where the spectrum resources are suitable for releasing does not reach the specific number, the first mobile communication system is considered to be unsuitable for releasing the frequency spectrum resources in a third preset time period in the future. Meanwhile, if the first mobile communication system is suitable for releasing the frequency spectrum resources in the third preset time period in the future, the frequency spectrum resources which can be released by the first mobile communication system most in the third preset time period in the future can be obtained further according to the condition of the service load data of each first cell after the first mobile communication system releases different frequency spectrum resources in the third preset time period in the future. According to the mode, whether the first mobile communication system is suitable for releasing the frequency spectrum resources in each third preset time period in the future is judged, and then a first time bitmap is generated, wherein the generated first time bitmap can directly indicate the frequency spectrum resources which can be released by the first mobile communication system at most in each time period suitable for releasing the frequency spectrum resources. For example, when it is evaluated whether the first mobile communication system (e.g., GSM system) of monday is suitable for releasing the spectrum resource in 9: 00-10: 00 (i.e., the third preset time period), it may be evaluated whether the first mobile communication system (e.g., GSM system) of monday is suitable for releasing the spectrum resource in 9: 00-10: 00 by using the fifth service load data of 9: 00-10: 00 every monday of the previous weeks. By analogy, whether the first mobile communication system (for example, a GSM system) is suitable for releasing the spectrum resources in each of a plurality of third preset time periods different from each other can be evaluated in this way. It should be further noted that the granularity of the first time bitmap may be hours or a shorter time period.
The second implementation manner is as follows: and generating a first time bitmap according to the service load data of the first cell of the first mobile communication system and the utilization rate of the data traffic and material resource blocks of the second cell of the second mobile communication system (such as an LTE system). Specifically, sixth service load data of a first cell of a first mobile communication system in a frequency spectrum resource sharing area in a historical time period corresponding to each fourth preset time period are obtained, and a second time bitmap of the first mobile communication system capable of releasing frequency spectrum resources is generated according to the obtained sixth service load data, wherein the fourth preset time periods are different from each other; and meanwhile, generating a third time bitmap of the second mobile communication system needing spectrum resource expansion according to the data traffic and the utilization rate of the physical resource block of a second cell of the second mobile communication system in a historical time period corresponding to each fifth preset time period in the spectrum resource sharing area (the third time bitmap can directly indicate the spectrum resource of the second mobile communication system which can be expanded in the time period needing spectrum resource expansion), wherein each fifth preset time period is different from each other, and finally generating the first time bitmap according to the second time bitmap and the third time bitmap. It should be noted that the accuracy of the first time bitmap generated by the second implementation is higher.
Wherein, the step of generating the third time bitmap specifically includes: judging whether the data flow of the second cell in the fifth preset time period exceeds a preset flow value or not and whether the utilization rate of the physical resource block exceeds a preset utilization rate or not, when the data flow of the second cell in the fifth preset time period exceeds the preset flow value and the utilization rate of the physical resource block exceeds the preset utilization rate, determining that the second cell needs to spread spectrum resources, counting the number of the second cells needing to spread spectrum resources in the spectrum resource sharing area after judging whether each second cell in the spectrum resource sharing area needs to spread spectrum resources or not in this way, and judging whether the number of the second cells needing to spread spectrum resources in the spectrum resource sharing area is larger than a fourth preset value (the fourth preset value can be set by a user according to experience). When the number of second cells needing spread spectrum resources in the spectrum resource sharing area is larger than a fourth preset value, determining that the second mobile communication system needs to spread spectrum resources in a fifth preset time period, and thus determining that the second mobile communication system needs to spread spectrum resources in a fifth preset time period in the future; and when the number of the second cells needing the spread spectrum resources in the spectrum resource sharing area is smaller than or equal to a fourth preset value, determining that the second mobile communication system does not need the spread spectrum resources in a fifth preset time period, thereby determining that the second mobile communication system does not need the spread spectrum resources in the fifth preset time period in the future. Meanwhile, if the second mobile communication system needs to expand the spectrum resources in the fifth preset time period in the future, the spectrum resources which can be expanded most in the fifth preset time period in the future of the second mobile communication system can be obtained according to the data traffic and the utilization rate of the physical resource blocks of each second cell after the second mobile communication system expands different spectrum resources in the fifth preset time period in the future. The fifth preset time period may be any time period (for example, 9:00 to 10:00 on Monday), and therefore, it can be seen that, in this way, it can be determined which time periods of the second mobile communication system in the future need to spread spectrum resources, and further, the third time bitmap can be obtained, and the third time bitmap can directly indicate the spectrum resources of the second mobile communication system that can be spread in the time periods that need to spread spectrum resources.
