Currently, the main means of indoor wireless signal coverage are divided into two categories, namely, traditional indoor distribution systems and digital indoor distribution systems.
The traditional indoor distribution system mainly carries out signal distribution and propagation through a feeder line and consists of three parts, namely an information source, a passive device and an antenna: the signal source is mainly a combination mode of a baseband processing Unit (BBU for short) and a Radio Remote Unit (RRU for short). The base band BBU is intensively placed in a machine room or adjusted to be indoor according to actual conditions, the RRU can be installed on a floor to be closer to the antenna feed side, the optical fiber is directly connected to the RRU from the BBU, and base band digital signals are transmitted between the BBU and the RRU. Passive devices include 1/2 feed lines, 7/8 feed lines, power splitters, couplers, combiners, and the like. Radio frequency signals sent by RRUs (radio remote units) are uniformly distributed to all indoor coverage required positions in a reasonable combination mode of passive devices such as feeder lines, power dividers, couplers and the like. In the process, the loss of radio frequency signals is in the whole system of the passive device. The antenna mainly comprises a ceiling antenna, a directional antenna, a plate antenna, a special beautifying antenna and the like. The device has the characteristics of small volume, easy installation, low gain power, easy leakage control and convenient filling of an indoor area by the main lobe. The capacity of the traditional indoor distribution system is difficult to dynamically adjust, and the configuration of the BBU and the RRU determines the upper limit of the capacity of a covered area.
The digital indoor distribution system is mainly used for signal distribution and propagation through a network cable and comprises three parts, namely a baseband unit, a relay connection control unit and an integrated radio remote unit: the baseband unit mainly processes baseband signals, and the baseband unit is connected with the relay connection control unit mainly through optical fibers; the relay connection control unit is mainly used for receiving downlink baseband data sent by the baseband unit, sending the downlink baseband data to the integrated remote radio unit after shunt processing, receiving uplink baseband data sent by the integrated remote radio unit, sending the uplink baseband data to the baseband processing unit after combination processing, internally provided with an active Ethernet (POE) Power supply circuit and supplying Power to the integrated remote radio unit through PoE, and the integrated remote radio unit integrates a remote radio module and an antenna, so that a radio frequency signal is processed, and the function of the antenna is realized.
The current resource allocation schemes based on the digital indoor distribution system are as follows:
scheme one, indoor coverage system of a resource adjustable: the relay link control unit collects the signals sent by the lower remote units, calculates the transmitting resources required by each remote unit to receive the signals, and configures the transmitting resources of the system according to the calculated result. According to the scheme, the allocation and the capacity adjustment can be selected according to system resources, and a plurality of standard signals cover the same network, so that the requirement of formulating the burst service of the subdivision area is met, and the user experience is improved.
Scheme two, a resource management method, device and system of the indoor distributed antenna system: configuring a plurality of radio frequency transceiving channels according to the requirement of indoor network coverage; and allocating baseband resources to the radio frequency transceiving channels according to an agreed resource allocation rule, and indicating the plurality of radio frequency transceiving channels to convert the baseband resources into radio frequency resources and send the radio frequency resources to users. According to the scheme, the baseband resources can be allocated to the plurality of radio frequency transceiving channels according to the agreed resource allocation rule, the network capacity is improved, the resource allocation of the plurality of radio frequency transceiving channels is realized, and the network resource allocation is flexible and convenient.
The problem that resources can not be dynamically adjusted exists in the traditional indoor distribution system:
the first scheme has the following disadvantages: according to the scheme, after the power of the downlink direction transmitting point in the indoor distribution system is adjusted, the corresponding coverage area is changed. When the resources of a plurality of transmitting points are adjusted to one transmitting point, a weak coverage area and even a blind area may occur. This is not in accordance with the basic principle of uniform distribution of indoor distributed signal strength. The scheme belongs to the effect of sacrificing the whole effect of indoor coverage to achieve the resource adjustment of partial areas.
The second scheme has the following disadvantages: when the single-station service requirement is in a stage valley, the station resource cannot be called from the station, and the station resource is applied to a target station with actual requirement. The phenomenon of low resource utilization rate at the level of physical sites is very common in observation from the perspective of the whole network. According to the data statistics result, the traffic distribution of the indoor sites conforms to the twenty-eight principle, wherein the first 20% of sites occupy 80% of traffic, and the sum of the traffic of the last 50% of sites occupies only 3% of the total traffic. The existing network has a large amount of free resources which can be adjusted, but the resources are not effectively utilized.
In view of the above problems, embodiments of the present invention provide a method for allocating baseband resources, where when determining that a baseband resource utilization rate of each logical cell of a first physical station in an assigned resource pool in a monitoring period is less than a service overload threshold, if the first physical station does not satisfy a first preset condition, determining whether to start an allocation operation according to the baseband resource utilization rate of each logical cell in the monitoring period; therefore, the baseband resource utilization rate of the physical station or the logical cell in the specified resource pool can be adjusted, so that the baseband resource utilization rate of each logical cell in the specified resource pool is ensured, and the specific implementation mode is as follows:
example one
An embodiment of the present invention provides a method for allocating baseband resources, as shown in fig. 1, including:
s101, obtaining the baseband resource utilization rate of each logic cell in the appointed resource pool in a monitoring period; wherein the designated resource pool comprises at least one physical station, each physical station comprises at least one logical station, and each logical station comprises at least one logical cell.
It should be noted that a logical cell refers to a minimum unit of a radio baseband resource required for carrying station traffic, a logical station refers to a radio baseband resource carrying unit under a physical station, and may be composed of one or more logical cells, and a physical station refers to a resource set required by a whole indoor distribution system station.
The utilization rate of the baseband resource of the logical cell in the monitoring period as shown in fig. 3 is equal to the used baseband resource divided by the total baseband resource of the logical cell; the utilization rate of the baseband resources of the logic station in the monitoring period is equal to the used baseband resources divided by the total baseband resources of the logic station; the utilization rate of the baseband resource of the physical station in the monitoring period is equal to the used baseband resource divided by the total baseband resource of the physical station.
For example, we can set the same first initial baseband resource for each logical station, and set the same second initial baseband resource for each logical cell, so as to be more convenient for management; wherein the first initial baseband resource is equal to the sum of the second initial baseband resources of all the logical cells in the logical station.
S102, when determining that the baseband resource utilization rate of each logic cell of a first physical station in a specified resource pool in a monitoring period is smaller than a service overload threshold, if the first physical station does not meet a first preset condition, determining whether to start allocation operation according to the baseband resource utilization rate of each logic cell in the monitoring period; the first preset condition includes that the first physical station only includes one logical station, the logical station only includes one logical cell, and the baseband resource utilization rate of the logical station is less than the service idle threshold, and the allocation operation includes any one of logical cell combining and logical station combining.
It should be noted that the logical cell merging refers to merging a first logical cell and a second logical cell in the same logical station into one logical cell, and at this time, users in the first logical cell and the second logical cell are both migrated to the merged logical cell; since the initial baseband resources allocated to each logical cell are the same, the initial baseband resources of one logical cell can be released after the logical cells are combined.
The logical station merging refers to merging a first logical station and a second logical station in the same physical station into one logical station, and at this time, users of the first logical station and the second logical station are both migrated to the merged logical station; since the initial baseband resource of each logical station is the same, the initial baseband resource of one logical station can be released after the logical stations are combined.
S103, when the start of the logic cell combination is determined, the logic cell combination is carried out on the logic cells in the appointed resource pool in the next monitoring period, so that the users in the logic cells carrying out the logic cell combination are moved to the logic cells after the logic cell combination.
Alternatively, the first and second electrodes may be,
and S104, when the logic station combination is determined to be started, performing logic station combination on the logic stations in the appointed resource pool in the next monitoring period so as to transfer users in the logic stations subjected to the logic station combination to the logic stations subjected to the logic station combination.
It should be noted that, in practical applications, when the logical station combining is started, it is indicated that both the two logical stations only include one logical cell, and the baseband resource utilization rate of the logical cell is lower than the service idle threshold, so that the logical station combining is performed on the two logical stations, which is equivalent to combining the logical cells of two different logical stations, that is, the logical station after the logical station combining still includes only one logical cell; the migration of the user to the logical station after the logical station combination is also equivalent to the migration to the logical cell in the logical station after the logical station combination.
Optionally, the allocating operation includes logical cell merging; determining whether to start allocation operation according to the baseband resource utilization rate of each logical cell in the monitoring period, as shown in fig. 2, includes:
s1020, if a first logical cell and a second logical cell which meet a second preset condition in the first physical station are determined, starting logical cell combination; the second preset condition includes that the baseband resource utilization rates of any two logic cells in the same logic station are both smaller than a service idle threshold.
When determining to start the logical cell merging, performing the logical cell merging on the logical cells in the specified resource pool in the next monitoring period so as to migrate the users in the logical cells performing the logical cell merging to the logical cells after performing the logical cell merging, including:
s1030, when it is determined that the logical cell merging is started, performing logical cell merging on the first logical cell and the second logical cell in the next monitoring period, so as to migrate users in the first logical cell and the second logical cell to the logical cell after the logical cell merging.
It should be noted that, in practical applications, when the utilization rate of the baseband resource of a logical cell is less than the service idle threshold, it indicates that there are fewer users carried in the logical cell at this time; if the baseband resource utilization rate of a plurality of logic cells in one logic station is less than the service idle threshold, the baseband resource wasted by the whole logic station is more; therefore, the logical cells in the logical station can be combined, and the baseband resource utilization rate of the logical station can be improved while more baseband resources are released.
Optionally, the allocation operation includes logical station merging; determining whether to start allocation operation according to the baseband resource utilization rate of each logical cell in the monitoring period, as shown in fig. 2, includes:
s1021, when a first logical station and a second logical station which meet a third preset condition exist in the first physical station, starting logical station combination; the third preset condition includes that the logic station only includes one logic cell, and the baseband resource utilization rate of the logic cell is smaller than the service idle threshold.
When determining to start the logic station combination, performing the logic station combination on the logic station in the designated resource pool in the next monitoring period so as to migrate the user in the logic station performing the logic station combination to the logic station after performing the logic station combination, including:
and S1040, when the logic station combination is determined to be started, performing logic station combination on the first logic station and the second logic station in the next monitoring period, so that users in the first logic station and the second logic station can be migrated to the logic station after the logic station combination.
It should be noted that, in practical applications, if a logical station only includes one logical cell after a plurality of monitoring periods, if the baseband resource utilization rate of the logical cell is still less than the service idle threshold, since there is no logical cell in the logical station that can perform logical cell merging with the logical cell, the logical cell merging cannot be triggered at this time; therefore, it is required to determine whether there are other logical stations satisfying a third preset condition in the physical stations corresponding to the logical station; if the baseband resources exist, the two logical stations can be combined, so that the baseband resource utilization rate of the physical station corresponding to the logical station can be improved while more baseband resources are released.
Optionally, the allocation operation further includes physical station level resource sharing; as shown in fig. 2, the method further comprises:
s105, when the first physical station is determined to meet a first preset condition, if a second physical station meeting a fourth preset condition still exists in the appointed resource pool, physical station level resource sharing is started; the fourth preset condition includes that at any time in the last monitoring period, the utilization rate of the baseband resources determined according to the sum of the used baseband resources of the first physical station and the used baseband resources of the second physical station is smaller than the service idle threshold.
It should be noted that, at any time in the previous monitoring period, the determined baseband resource utilization rates are all smaller than the service idle threshold according to the sum of the used baseband resource of the first physical station and the used baseband resource of the second physical station, which means that at each time in the previous monitoring period, the baseband resource allocation device may determine the baseband resource utilization rate at each time in the previous monitoring period according to the sum of the used baseband resource of the first physical station and the used baseband resource of the second physical station at each time in the previous monitoring period, and only when the baseband resource utilization rate at each time is smaller than the service idle threshold, the physical station level resource sharing between the second physical station and the first physical station may be started.
S106, when starting the physical station level resource sharing is determined, carrying out physical station level resource sharing on the first physical station and the second physical station in the next monitoring period so as to transfer users in the first physical station and the second physical station to the physical station after the physical station level resource sharing is carried out; and the second physical station is a physical station which meets a third preset condition in the last monitoring period and has the baseband resource utilization rate less than or equal to a specified threshold.
In practical application, when two physical stations in the same resource pool open physical station level resource sharing, assuming that a first physical station satisfies a first preset condition, it indicates that there are fewer users carried by the first physical station at this time, and therefore it is necessary to search whether there is a second physical station satisfying a fourth preset condition in a resource pool corresponding to the first physical station; if the user resource sharing exists, it is indicated that the users borne by the second physical station are fewer (i.e., the remaining baseband resources are more), so that the user of the first physical station is migrated to the second physical station (the baseband resources of the first physical station are released, and only the baseband resources of the second physical station are used), at this time, the second physical station not only contains the user borne by itself, but also needs to bear the user of the first physical station, and after the physical station level resource sharing between the first physical station and the second physical station is started as shown in fig. 4, the user experience is ensured, and at the same time, the baseband resource utilization rate of the second physical station can be improved.
As can be seen from the foregoing solution, with the baseband resource allocation method provided in the embodiment of the present invention, when the baseband resource utilization rate of each logical cell of the first physical station in the specified resource pool in the monitoring period is smaller than the service overload threshold, it indicates that there are fewer users borne by the first physical station at this time, and therefore, it is determined whether to start allocation operation according to the baseband resource utilization rate of each logical cell in the monitoring period; when the allocation operation is started, all users are migrated to the logic cell or the logic station after the allocation operation, so that more users are borne in the logic cell or the logic station after the allocation operation, the baseband resource utilization rate of the logic cell or the logic station is improved, and the baseband resource utilization rate of the specified resource pool is improved; the problem of the resource utilization ratio of baseband resource among the prior art on the low side is solved.
