As shown in the figure, the switching units in the centralized baseband pool are classified into two types, one for ensuring basic switching needs. , marked as "cannot be powered off", as shown by the solid line units a, c, e in Figure 3, one type used to share the switching network capacity, marked as "can be powered down", as shown by the dotted line unit b in Figure 3, d, f, the topology between the switching units a, c, e, and the topology between the switching units c, e and the baseband processing units BBU1 to BBU8 are basic topology networks (as shown in Figure 3) Line connection line), topology between switching units b, d, f, topology between switching unit d, f and switching unit a, switching unit d, f and baseband processing unit BBU1 to BBU8 The topology is an extended topology network (shown by the dotted line in Figure 3).

Thus, that is, the resource scheduler selects a topology path in the extended topology network to implement data exchange between the directly connected baseband processing unit and the baseband processing unit for the dynamic cell.

If the resource scheduler determines that the activated cell is a dynamic cell, referring to FIG. 3, if the remote radio unit corresponding to the dynamic cell is RRU2, and the baseband processing unit to be allocated with the "powerable" flag is BBU3 and BBU6, The resource scheduler establishes a topology path between the RRU2 and the BBU3 when the dynamic cell meets the deactivation condition in a non-predetermined power-saving period: RRU2->switch unit d->BBU3. The resource scheduler obtains the node information of the topology path and the resource usage information of the BBU3. If the preset requirement to allocate the baseband resource to the dynamic cell is: the topology path corresponding to the baseband processing unit to be allocated is: The number of switching units is less than 4, and there are unallocated baseband resources in the powered-off physical unit. At this time, the resource scheduler determines, according to the node information, that the topology path passes through a switching unit d, and is determined according to the resource usage information of the BBU3. If the BBU3 has an idle baseband resource, the resource scheduler allocates the baseband resource on the BBU3 to the dynamic cell.

In addition, the resource scheduler may determine that the BBU 3 satisfies the condition that the baseband resource needs to be allocated to the dynamic cell by comparing the BBU 3 and the BBU 6. For example, the resource scheduler constructs an extension between the RRU2 and the BBU6. Park path: RRU2->switch unit d-> switch unit b -> switch unit f->BBU6. Thus, since the topology path corresponding to the BBU3 passes through a switching unit d, the topology path corresponding to the BBU6 passes through the three switching units d, b, f. Therefore, if the BBU3 has idle baseband resources at this time, the resource The scheduler allocates the baseband resources on the BBU3 to the dynamic cell.

It should be noted that constructing a topology path by using a "power-down" label switching unit as described in the embodiment of the present invention is a priority strategy, that is, in an exchange unit with a "power-down" flag. When there is an idle exchange resource, the resource scheduler can also construct the topology path through a switching unit with a "non-powerable" flag.

If the resource scheduler determines that the activated cell is a coverage area, referring to FIG. 3, the radio remote unit corresponding to the coverage area is RRU1, and the baseband processing unit with the "unpowerable" flag is BBU4 and BBU5. When the resource scheduler determines that the coverage area meets the activation condition, the topology path between the RRU1 and the BBU4 is set up: RRU1_> exchange unit c->BBU4, and the topology path between the RRU1 and the BBU5 is set up: RRUl -> Switching unit c_> Switching unit a_> Switching unit e_>BBU5. Thus, since the topology path corresponding to the BBU 4 passes through a switching unit c, the topology path corresponding to the BBU 5 passes through the three switching units c, a, e. Therefore, if the BBU 4 has idle baseband resources at this time, the resource The scheduler allocates the baseband resources on the BBU 4 to the coverage area.

Further, the implementation manner of performing the deactivation operation or the cell migration operation on the dynamic cell includes the following five types:

The first de-activation processing unit 21 is configured to: determine that a dynamic cell of a virtual base station coverage cell meets a preset deactivation threshold condition, and control the baseband processing unit used by the dynamic cell, where the dynamic cell is used. Perform a deactivation operation.

Manner 2: The deactivation processing unit 21 is specifically configured to: determine that a traffic volume of a dynamic cell covering a cell of a virtual base station does not meet a preset deactivation threshold condition, and control the motion. The radio remote unit used by the state cell reduces the signal transmission power of the dynamic cell, so that the service of the dynamic cell is switched to the neighboring cell, and the traffic of the dynamic cell is reduced, until the service volume of the dynamic cell is determined to be less than a preset. Deactivating the threshold, controlling the baseband processing unit used by the dynamic cell, and performing a deactivation operation on the dynamic cell.

The third method, the deactivation processing unit 2 is specifically configured to: switch the service of the dynamic cell to the coverage area by using a handover procedure in the mobile communication network, control a baseband processing unit used by the dynamic cell, and prohibit new service connection. Entering the dynamic cell to reduce the traffic of the dynamic cell, until determining that the traffic volume of the dynamic cell is less than a preset deactivation threshold, controlling the baseband processing unit used by the dynamic cell, and performing a deactivation operation on the dynamic cell .

And the deactivation processing unit 2 is specifically configured to: control a baseband processing unit used by the dynamic cell, and perform a deactivation operation on the dynamic cell; the cell activation unit 27 is further configured to activate the dynamic cell, and The baseband resources on the baseband processing unit with the "non-powerable" flag are assigned to the dynamic cell.

Manner 5: The cell migration unit 2 2 is specifically configured to dynamically migrate a dynamic cell of a virtual base station coverage cell to the baseband processing unit with the “unpowerable” flag.

The resource scheduler is configured to release the baseband resources occupied by the dynamic cell, where the centralized baseband pool sets a status identifier corresponding to each baseband resource, when the baseband resource is allocated to the cell. The status identifier corresponding to the baseband resource indicates that the baseband resource is in the bu sy state. At this time, the resource scheduler cannot allocate the baseband resource to other cells; when the baseband resource is not allocated, the status identifier indication corresponding to the baseband resource The baseband resource is in a free state, and the resource scheduler can allocate the baseband resource to the cell. In this way, when the traffic of the cell decreases and decreases to the threshold of cell deactivation, the resource scheduler deactivates the cell, and changes the state identifier of the baseband resource allocated to the cell from bu sy to Free , completes the return of the baseband resource to the centralized baseband pool.

It should be noted that, in the foregoing implementation manner of performing the deactivation operation or the cell migration operation independently, the mode 1 is used as an optimal implementation manner, and In the preset energy saving period, the resource scheduler may also perform the non-preset energy saving period, so that the resource scheduler may select any one of the implementation manners 2 to 5 on the basis of the first method, that is, The resource scheduler performs mode 1 in the non-preset energy-saving period, and when entering the preset energy-saving period, first determines whether the traffic of the dynamic cell satisfies the threshold condition of the cell deactivation, and if not, the resource scheduler Choose one of the five ways to implement the implementation.

The preset energy-saving period may be indicated by an energy-saving time parameter, where the time-saving parameter may be configured by the user to indicate a start time and an end time of the energy-saving processing performed by the resource scheduler on the baseband processing unit.

In addition, the time energy saving parameter may also be generated by the network management system according to the traffic history statistics and sent to the centralized baseband pool for configuration.

Specifically, since the service traffic of the base station at different times is very different, the working time is generally the largest when the working time is from 8:00 am to 18:00, and the rest time is from 0:00 am to 6:00 am. The system can calculate the busy hour and idle time of the daily traffic of the base station cloud, and obtain historical statistics of the traffic volume. Based on this, the network management system can calculate the best "energy saving start time" and "energy saving and consumption reduction" Time", generates energy saving time parameters.

It should be noted that, in the fourth mode, the resource scheduler preferentially allocates the baseband resource on the baseband processing unit with the "unpowerable" flag to the dynamic cell in the preset energy saving period, and the specific process may refer to the foregoing The resource scheduler should assign a description of the baseband resources on the baseband processing unit with the "powerable" flag to the dynamic cell.

The following five optional implementations are illustrated below:

For example, FIG. 4( a ) is a schematic diagram of a base station cloud allocating baseband resources to a cell in a non-predetermined power saving period. The accessing base station VBTS-A has two cells, where CELL-A1 is a coverage area, and is deployed in The baseband processing unit BBU1 with the "non-power-off"flag; CELL-A2 is a dynamic cell, deployed on the BBU3 with the "power-down" baseband processing unit, and a topology path needs to be established with the RRU1 through the switching unit. There are two cells in the access base station VBTS-B, where CELL-B1 is a coverage area and is deployed on the BBU2 with the "unpowerable" baseband processing unit; CELL-B2 is a dynamic cell, deployed with "可可" Power off the baseband processing unit BBU5 and establish a topology path with the RRU2 through the switching unit.

It should be noted that the solid line functional unit in Figure 4 (a) is a physical unit with "non-power-off", and the physical unit of the dotted line is a physical unit with "power-off", the physical unit includes baseband processing. Units and switching units, thick solid lines are used to represent topological paths in the basic topology network, and thick dashed lines are used to represent topological paths in the extended topology network.

Using the technical solution of the present invention, a schematic diagram of the centralized baseband pool allocating baseband resources to the cell in a preset energy saving period is shown in FIG. 4(b). The access base station VBTS-A has a cell CELL-A1, wherein the CELL-A1 is a coverage area, and is deployed on the baseband processing unit BBU1 with the "unpowerable" flag. There are two cells accessing the base station VBTS-B, where CELL-B1 is a coverage area and is deployed on the baseband processing unit BBU2 with the "unpowerable" flag; CELL-B2 is a dynamic cell, deployed with The "can be powered down" marked baseband processing unit BBU1, and a topology path needs to be established with the RRU1 through the switching unit.

In a possible implementation manner of the embodiment of the present invention, as shown in FIG. 4( a ) and FIG. 4 ( b ), when the traffic volume in the VBTS-A coverage area decreases, if the traffic volume decreases to reach CELL-A2 deactivation. The traffic volume is wide, CELL-A2 is automatically deactivated, and the baseband resources on BBU3 are released. The BBU3 can be powered off, and the topology path of RRU1 to BBU3 does not need to be established, and the load of the switching unit on the corresponding topology path is also reduced. For the switching unit that does not assume other topology paths, it can also be powered off.

In another possible implementation manner of the embodiment of the present invention, the traffic volume of the VBTS-A coverage area is reduced, but the traffic volume value of the CELL-A2 deactivation is not reached, and the resource scheduler is preset to the energy saving period. The base station signal transmission power of the CELL-A2 is continuously lowered, forcing the user to switch to the CELL-A1. When the CELL-A2 service is further degraded and reaches the CELL-A2 deactivated traffic threshold, the CELL-A2 can be automatically deactivated, the baseband resources on the BBU3 are released, and the BBU3 can be idle after the BBU3 is idle. Power off the BBU3.

In another possible implementation manner of the embodiment of the present invention, the VBTS-A coverage area The traffic volume is reduced, but the traffic volume of CELL-A2 deactivation is not reached. When the energy saving period is reached, the base station cloud switches the CELL-A 2 user to CELL-A 1 and prohibits new services in CELL- A2 access. When the CELL-A2 service is further degraded and reaches the CELL-A2 deactivated traffic threshold, the CELL-A2 can be automatically deactivated, the baseband resources on the BBU3 are released, and the BBU3 can be idle after the BBU3 is idle. The BBU3 is powered off.

In another possible implementation manner of the embodiment of the present invention, although the traffic volume of the VBTS-B coverage area is reduced, but the traffic value of the CELL-B2 deactivation is not reached, the CELL-B2 still needs to use the baseband resource. . When the preset energy-saving period is reached, the resource scheduler first activates CELL-B2. At this time, the baseband resource of BBU5 occupied by CELL-B2 is released; then CELL-B2 is activated again, and CELL-B2 will re-apply with "" Do not power off the baseband resources on the baseband processing unit, such as BBU1. At this time, the BBU5 can be powered off, and the switching unit that does not undertake other topology path switching can also be powered off. In this scenario, although the number of baseband resources used is not reduced, since the baseband resources to be used are concentrated on the baseband processing unit with the "unpowerable" flag, the baseband resource utilization is improved, and the build extension is reduced. The number of exchange units required for the Park path can therefore achieve the purpose of energy saving.

In another possible implementation manner of the embodiment of the present invention, although the traffic of the VBTS_B coverage area is reduced, but the traffic volume of the CELL-B2 deactivation is not reached, the CELL-B2 still needs to use the baseband resource. After the preset power-saving period, the resource scheduler dynamically migrates the baseband resources occupied by the CELL-B2 from the BBU5 to the BBU1. In this scenario, although the number of baseband resources used is not reduced, since the baseband resources to be used are concentrated on the baseband processing unit with the "unpowerable" flag, resource utilization is improved, and the topology is reduced. The number of switching units required for the path, so energy saving can be achieved.

Optionally, the periodic scanning unit 24 is further configured to periodically scan the switching unit with the "power-off" flag to determine whether the switching unit carries the exchange data. The energy-saving indicating unit 25 is further configured to indicate the energy-saving execution device. A power-off operation is performed on the switching unit that does not carry data exchange and has the "power-down" flag.

For example, the resource scheduler determines that the current time of the centralized baseband pool is in advance During the energy saving period, the cyclic scan timer is started, and when it is determined that the cyclic scan timer expires, the resource scheduler obtains the baseband resource usage information on the N baseband processing units with the "powerable" flag. N is a natural number, and determines whether the baseband processing unit is in an idle state according to the baseband resource usage information, and performs a power-off operation on the baseband processing unit in an idle state. After determining that all baseband processing units with "power-down" flags are scanned, the resource scheduler cyclically acquires switching resources on the switching unit with the "power-down" flag according to the timing time of the cyclic scan timer. The information is used, and the switching unit in the idle state is determined according to the exchange resource usage information, and the switching unit is powered off until the resource scheduler scans all the switching units with the "powerable" flag.

It should be noted that the resource scheduler may also scan the baseband board in the minimum power-down unit, such as the baseband processing unit, to obtain the baseband resource usage information of the N baseband boards, where N is a natural number, and no baseband is used. The minimum power-down unit used by the resource is powered down, and after determining that the baseband boards in the baseband processing unit have been powered down, the baseband processing unit is powered off.

Optionally, the energy-saving indicating unit 25 is further configured to instruct the energy-saving executing device to perform a power-on operation on the baseband processing unit or the switching unit that has implemented the power-off operation.

It will be apparent to those skilled in the art that, for convenience and brevity of description, only the division of each functional module described above is exemplified. In practical applications, the above-mentioned function assignment can be completed by different functional modules as needed. The internal structure of the device is divided into different functional modules to perform all or part of the functions described above. For the specific working process of each unit described above, refer to the corresponding process in the method embodiment, and the respective functional units of the resource scheduler 20 can be used in the steps in the method embodiment, and details are not described herein again.

Using the resource scheduler, the resource scheduler allocates a baseband resource on a baseband processing unit with a "powerable" flag to a dynamic cell, such that deactivation or cell migration is performed on all dynamic cells of the baseband processing unit. After releasing the baseband unit and providing the dynamic baseband resource, the base with the "powerable" flag is The band processing unit is not involved in the service processing, so that the power of the baseband processing unit can be turned off, thereby achieving energy saving and consumption reduction on the baseband processing unit. The embodiment of the present invention provides a device control method in a centralized baseband pool architecture. As shown in FIG. 5, the execution body of the method is the resource scheduler 20 provided by the foregoing device embodiment, and includes:

S5 01: The resource scheduler performs a deactivation operation or a cell migration operation on a dynamic cell of a virtual base station coverage cell. Meanwhile, the baseband resource on the baseband processing unit occupied by the dynamic cell is released.

The virtual base station coverage cell includes a dynamic cell and a coverage area, and the baseband processing unit used by the dynamic cell has a "power off" flag, and the baseband processing unit used by the coverage area has a "cannot be powered" flag.

Specifically, the resource scheduler performs a deactivation operation or a cell migration operation on the dynamic cell by using the following five implementation manners:

In a first step, the resource scheduler controls the baseband processing unit used by the dynamic cell to perform a deactivation operation on the dynamic cell when determining that the traffic volume of the dynamic cell of the virtual base station coverage cell meets the preset deactivation threshold condition. At the same time, the baseband resource on the baseband processing unit occupied by the dynamic cell is released.

Manner 2: In the preset energy saving period, the resource scheduler controls the radio remote unit used by the dynamic cell when determining that the dynamic cell of the virtual cell covering the cell does not meet the preset deactivation threshold The signal transmission power of the dynamic cell is reduced, so that the service of the dynamic cell is switched to the neighboring cell, and the traffic of the dynamic cell is reduced, until the resource scheduler determines that the traffic of the dynamic cell is smaller than a preset deactivation. And the resource scheduler controls the baseband processing unit used by the dynamic cell to perform a deactivation operation on the dynamic cell; and simultaneously releases the baseband resource on the baseband processing unit occupied by the dynamic cell.

In a preset energy saving period, the resource scheduler switches the service of the dynamic cell to the coverage area through a handover procedure in the mobile communication network, and controls the baseband processing unit used by the dynamic cell to prohibit new The service accesses the dynamic cell, To reduce the traffic of the dynamic cell, until the resource scheduler determines that the traffic volume of the dynamic cell is less than a preset deactivation threshold, the resource scheduler controls the baseband processing unit used by the dynamic cell, and the dynamic cell Performing a deactivation operation; at the same time, releasing the baseband resource on the baseband processing unit occupied by the dynamic cell.

In a preset energy saving period, the resource scheduler controls the baseband processing unit used by the dynamic cell, performs a deactivation operation on the dynamic cell, and releases the baseband resource on the baseband processing unit occupied by the dynamic cell. Thereafter, the dynamic cell is reactivated, and the baseband processing unit with the "unpowerable" flag is assigned to the dynamic cell.

In a preset energy saving period, the resource scheduler dynamically migrates the dynamic cell to the baseband processing unit with the "unpowerable" flag, and releases the "powerable" flag. The baseband processing unit is the baseband resource provided by the dynamic cell.

It should be noted that, in the foregoing manners 1 to 5, an implementation manner of performing a deactivation operation or a cell migration operation on the dynamic cell is performed separately, where the mode 1 is an optimal implementation manner, and the method may be performed in a preset energy saving period. The resource scheduler can also perform the implementation mode 2 to mode 5 on the basis of the mode 1, that is, the resource scheduler is not preset. The energy saving period is performed in the first mode, and when entering the preset energy saving period, it is first determined whether the traffic of the dynamic cell satisfies the threshold condition of the cell deactivation. If not, the resource scheduler selects the second mode to the fifth mode. Any of the implementations are implemented.

S5 02. The resource scheduler periodically scans each baseband processing unit with the “power-down” flag during a preset power-saving period, and performs a power-off operation on the baseband processing unit in which the baseband resources are all released.

It should be noted that the baseband processing unit includes at least one baseband board, where the baseband board is the smallest unit that provides baseband resources to the cell, that is, in each baseband processing unit with the "powerable" flag. The baseband board is the smallest power-off unit. In a possible implementation manner of the present invention, the resource scheduler uses the baseband board in the baseband processing unit as the scanning granularity during the energy-saving period, and is used for the non-baseband resource. Base The strip is powered down, and after all of the baseband boards in the baseband processing unit are powered down, a power off operation is further performed on the baseband processing unit.

In this way, in order to enable the baseband processing unit with the "power-down" flag to be in an idle state after releasing the baseband resource occupied by the dynamic cell, that is, no baseband resource is used, the resource scheduler allocates the baseband resource to the activated cell, specifically including The resource scheduler obtains energy-saving attribute information of the baseband processing unit, where the energy-saving attribute information is used to mark the baseband processing unit as "power-off" or mark the baseband processing unit. If the "unable to power off", the resource scheduler allocates the baseband resource of the baseband processing unit marked as "powerable" to the dynamic cell when determining that the activated cell is a dynamic cell; When the cell is covered, the baseband resource of the baseband processing unit marked as "unpowerable" is allocated to the protected coverage cell.

According to the foregoing manners 4 and 5, the resource scheduler allocates baseband resources on the baseband processing unit marked as “unpowerable” for the dynamic cell and the coverage area in the preset energy saving period.

In addition, for the baseband resource on the baseband processing unit of the dynamic cell occupied by the resource scheduler in step S509, it should be noted that the resource scheduler releases the dynamic cell while deactivating the dynamic cell. If the resource scheduler is in the preset power saving period and the resources on the baseband processing unit are released, the resource scheduler directly performs power off on the baseband processing unit. If the resource scheduler is in the non-preset energy saving period, the resource splicer only releases the baseband resources occupied by the dynamic cell, and allocates the baseband resource to other cells to improve the utilization of the baseband resource. .

Optionally, the resource scheduler periodically scans the switching unit with the “powerable” flag during the preset power saving period, and performs power supply to the switching unit that carries the data exchange and has the label “powerable” flag. Close the operation.

It should be noted that, if the radio remote unit used by the activated cell is not directly connected to the baseband processing unit used by the activated cell, the resource scheduler needs a topology network formed by a switching unit in the centralized baseband pool. Determining between the baseband processing unit used by the activated cell and the baseband processing unit directly connected to the radio remote unit The extension of the data exchange path.

In a possible implementation manner of the present invention, the baseband processing unit allocates the baseband resource on the baseband processing unit to the activated cell, and specifically includes: the resource scheduler acquires energy-saving attribute information of the switching unit; the energy-saving attribute information is used to mark the The switching unit is "can be powered off" or marks the switching unit as "unpowerable"; when the resource scheduler determines that the activated cell is the dynamic cell, the resource scheduler carries the "can be powered down" And marking, in the baseband processing unit, a baseband processing unit that is connected with a radio remote unit used by the dynamic cell to extend a minimum path in the topology network; and assigning the selected baseband resource of the baseband processing unit to the dynamic a cell, wherein the extended topology network is constructed between the switching units with the "powerable" flag.

When the resource scheduler determines that the activated cell is the protected coverage cell, in the baseband processing unit with the "non-powerable" flag, select the radio remote unit used by the coverage area to a baseband processing unit connected to the minimum path in the network; assigning the selected baseband resource of the baseband processing unit to the protected coverage cell, wherein the basic topology network is in the exchange unit with the "non-powerable" flag Between, with the "power off" mark and the exchange unit with the "unpowerable" mark.

Optionally, the step of determining, by the resource splicer, that the baseband processing unit is marked as "powerable" comprises: acquiring, by the resource scheduler, a baseband used by the coverage area in each virtual base station coverage cell in the centralized baseband pool architecture The number of resources, and determining a baseband processing unit directly connected to the radio remote unit used by the coverage area, determining the baseband processing used by the coverage area according to the obtained quantity of the baseband resource and the determined baseband processing unit The unit, the resource scheduler marks the baseband processing unit used by the non-protected coverage cell in the centralized baseband pool architecture as the "powerable".

Further, after the preset energy saving period ends, the resource scheduler performs a power-on operation on the baseband processing unit or the switching unit that has implemented the power-off operation.

Using the above scheme, the baseband resource on the baseband processing unit with the "power-down" flag is allocated to the dynamic cell, so that after all the dynamic cells of the baseband processing unit are deactivated or the cell is migrated, the baseband unit is released. Provided to the dynamic community The baseband resource, at this time, the baseband processing unit with the "rechargeable" flag is not involved in the service processing, so that the power of the baseband processing unit can be turned off, thereby achieving energy saving and consumption reduction on the baseband processing unit.

The embodiment of the present invention achieves the purpose of energy saving and consumption reduction by implementing a power-off operation on a baseband processing unit with a "power-down" mark, but performs a shutdown on a baseband processing unit with a "power-down" mark. Before the power operation, it is determined that the dynamic cell corresponding to the baseband processing unit has been deactivated, and the baseband resources provided to the dynamic cell have been released. Therefore, the energy saving of the device depends on the resource allocation and cell deactivation of the cell activation. The process of resource release, the specific description of the foregoing steps S 5 01 and step S 5 02 includes a process of allocating a baseband resource process for activating a cell and a cell deactivating release baseband resource, which will be described in detail below.

In a possible implementation manner of the embodiment of the present invention, the method for the resource scheduler to allocate resources on the baseband unit to the activated cell, as shown in FIG. 5( a ), includes:

The S 5 01 resource scheduler marks the baseband processing unit as "can be powered down" or "cannot be powered down".

For example, the resource scheduler determines the number of coverage-protected cells according to the cell type information of all cells, and determines the number of baseband resources required to activate the coverage-protected cell, and the resource scheduler may also be covered according to the coverage-covered cell. The area information, the radio remote unit that covers the area is determined, and the baseband processing unit connected to the radio remote unit is determined by the device configuration information. For convenience of description, the baseband processing unit is referred to as a direct baseband processing unit, and the resource is The scheduler determines other baseband processing units that are close to the direct-connected baseband processing unit, wherein the distance refers to the distance of the topology path through which data is exchanged between the two baseband processing units, and can also be understood as two The number of exchange units that need to pass through the data exchange between the baseband processing units, the fewer the number of exchange units that pass, indicating the closer the distance between the two baseband processing units. And the resource scheduler may determine, according to the number of baseband resources required by the coverage area, the baseband marked as “unpowerable” in the directly connected baseband processing unit and the baseband processing unit that is closer to the directly connected baseband processing unit. The processing unit, and the remaining baseband processing unit is marked as "powerable" by using the energy saving attribute information. The cell type information may be configured by the user when the cell is created, and is used to indicate whether the cell is a dynamic cell or a coverage cell.

55012: The resource scheduler obtains cell type information of the activated cell, and determines whether the cell is a dynamic cell.

It should be noted that, for the coverage area, since the coverage area does not need to be activated or deactivated according to the traffic volume of the area, the user can activate the coverage area in the initial stage of creating the cell, and The resource scheduler indicates that the resource scheduler allocates resources for the coverage area; for the dynamic cell, the resource scheduler first obtains the traffic information of the area where the dynamic cell is located, where multiple cells can simultaneously cover one area, and the area may be A sector, the cell that can cover the area includes an inactive cell and an activated cell, and the resource scheduler starts the activation process and activates the area when determining that the traffic of the area reaches the traffic volume of the activated cell. Inactive cells in the cell. In addition, the resource scheduler activating the cell may be performed during the energy saving period of the base station cloud, or may be performed during the non-energy saving period.

Specifically, if the cell type information includes the dynamic cell identifier, the resource scheduler determines that the cell is a dynamic cell according to the dynamic cell identifier, and continues to perform steps S5013 to S5014, where the process ends; if the cell type information includes the coverage The cell identifier is determined by the resource scheduler according to the coverage area identifier, and the process proceeds to step S5015 to step S5016, and the process ends.

55013. The resource scheduler determines, in a baseband processing unit with a "power-down" flag, a baseband processing unit that provides baseband resources for the dynamic cell.

In a possible implementation manner of the embodiment of the present invention, the resource scheduler preferentially selects a baseband processing unit directly connected to the radio remote unit, if the directly connected baseband processing unit has an "unpowerable" flag, or the straight If there is no idle baseband resource on the baseband processing unit, the resource scheduler may further select an idle baseband resource baseband processing unit that is closer to the directly connected baseband unit and provide a baseband resource for the dynamic cell. As shown in FIG. 5(b), the baseband processing unit that the resource scheduler determines to provide the baseband resource for the dynamic cell in the baseband processing unit with the "power-down" flag specifically includes:

S5013 The resource scheduler constructs a topology path of the baseband processing unit to be allocated by using a switching unit with a "powerable" flag.

The baseband processing unit to be allocated is at least one baseband processing unit with a "power-down" mark that is closer to the directly connected baseband processing unit.

It should be noted that, according to the corresponding description in step S5011, after determining the baseband processing unit marked as “unpowerable”, the resource scheduler may also determine the topology of the internal switched network in the centralized baseband pool, according to With the number of baseband processing units with "non-powerable" and configuration information in a centralized baseband pool, the resource scheduler can determine the data exchange required to satisfy the baseband processing unit with the "non-powerable" flag. A switch unit that cannot be powered off, and marks the switch unit as "unpowerable" and marks the other switch unit as "can be powered off".

Referring to the description of FIG. 3 in the previous embodiment, FIG. 3 is a schematic diagram of a topology between the radio remote unit RRU1, RRU2 and the baseband processing units BBU1 to BBU2. As shown, the switching unit in the centralized baseband pool is shown. There are two types, one is used to ensure the basic exchange needs, marked as "cannot be powered off", as shown by the solid line units a, c, e in Figure 3, one type used to share the switching network capacity, marked as " Power off", as shown by the dashed lines b, d, f in Figure 3, the topology between the exchange units a, c, e, and the extension between the exchange units c, e and the baseband processing units BBU1 to BBU8 Park is the basic topology network (shown as the solid line in Figure 3), the topology between the exchange units b, d, f, the topology between the exchange unit d, f and the exchange unit a, the exchange unit The topology between d, f and baseband processing units BBU1 to BBU8 is an extended topology network (shown by the dotted line in Figure 3).

It should be noted that the description of the embodiment of the present invention is marked by "can be powered down". The switching unit is a preferred strategy for setting up the topology path. That is to say, when there is no idle switching resource in the switching unit with the "power-off" flag, the resource scheduler can also pass the "cannot be powered off."" The marked exchange unit sets up the topology path.

S50132. The resource scheduler acquires node information of the topology path and baseband resource usage information of the baseband processing unit to be allocated.

The baseband resource usage information is used to indicate whether there is an unallocated baseband resource in the baseband processing unit to be allocated, and the node information is the number of switching units through which the topology path passes.

S50133. The resource scheduler determines, according to the node information and the baseband resource usage information, that the baseband processing unit to be allocated satisfies the condition for allocating baseband resources to the dynamic cell.

It is to be noted that the condition that the power-off physical unit allocates the baseband resource to the dynamic cell may be configured by the user, for example, the preset condition: the switching unit of the topology path corresponding to the baseband processing unit to be allocated The number is less than N (N is a natural number), and there is an unallocated baseband resource in the baseband processing unit to be allocated.

The foregoing step S50131 to step S50133 are only a preferred implementation manner of the embodiment of the present invention. The resource scheduler may also randomly determine a baseband processing unit that provides baseband resources for the dynamic cell, which is not limited by the present invention.

S5014. The resource scheduler allocates a baseband resource of the baseband processing unit to the dynamic cell.

For example, referring to FIG. 3, the remote radio unit corresponding to the dynamic cell is RRU2, and the baseband processing unit to be allocated with the "powerable" flag is BBU3 and BBU6, if the resource scheduler is in a non-preset energy saving period. Determining that the dynamic cell meets the deactivation condition, and constructing a topology path between the RRU2 and the BBU3: RRU2->switching unit d->BBU3, the resource scheduler acquires node information of the topology path and the BBU3 The resource usage information, if the preset requirement for allocating the baseband resource to the dynamic cell is satisfied, the condition that the topology path corresponding to the to-be-assigned baseband processing unit passes is less than 4, and the number of the switchable physical unit is There are unallocated baseband resources. At this time, the resource scheduler determines, according to the node information, that the topology path passes through an exchange unit d. And determining, according to the resource usage information of the BBU3, that the BBU3 has an idle baseband resource, and the resource scheduler allocates the baseband resource on the BBU3 to the dynamic cell.

Optionally, the resource scheduler preferentially allocates the baseband resource on the baseband processing unit with the “non-powerable” flag to the dynamic cell in a preset energy saving period, and the specific process may refer to the corresponding resource scheduler. A description of the baseband resource on the baseband processing unit with the "powerable" flag is assigned to the dynamic cell.

The resource scheduler implements resource allocation of the dynamic cell through steps S5013 and S5014.

S5015. The resource scheduler determines, in a baseband processing unit with a "non-power-off" flag, a baseband processing unit that provides baseband resources for the coverage area.

Specifically, this step can refer to the detailed description of the corresponding step S5013.

S5016. The resource scheduler allocates a baseband resource of the baseband processing unit to the coverage area.

It should be noted that the resource scheduler allocates resources to the coverage area through steps S5015 and S5016. For details, refer to the corresponding description of step S5013 to step S5016.

For example, referring to FIG. 3, the radio remote unit corresponding to the coverage area is RRU1, and the baseband processing unit with the "unpowerable" flag is BBU4 and BBU5, and the resource scheduler determines that the coverage area meets activation. The topology path between the RRU1 and the BBU4 is set up: RRin -> Switching Unit c->BBU4, and the topology path between the RRU1 and the BBU5 is set up: 11111->Switching Unit. -> Exchange unit &->Switch unit e->BBU5. Thus, since the topology path corresponding to the BBU 4 passes through an exchange unit c, The topology path corresponding to the BBU 5 passes through the three switching units c, a, e. Therefore, if the BBU 4 has idle baseband resources at this time, the resource scheduler allocates the baseband resources on the BBU 4 to the coverage area.

The resource scheduler implements the activation of the cell by using the foregoing steps S5011 to S5016. The following describes the steps of the resource scheduler in the preset energy saving period by using the detailed embodiment.

In a possible implementation manner of the embodiment of the present invention, the method for performing energy-saving processing on the baseband processing unit by the resource scheduler in the preset energy-saving period is as shown in FIG. 5(c), and includes:

The S502 resource scheduler determines that the current time of the centralized baseband pool is within a preset energy saving period.

Specifically, the network management system generates the energy saving time parameter according to the historical traffic statistics information and sends the energy saving time parameter to the centralized baseband pool for configuration, and the resource scheduler determines, according to the energy saving time parameter, whether the current time of the centralized baseband pool is preset. During the energy saving period.

It should be noted that the service traffic of the base station at different times is very different. Generally speaking, the working time is the largest from 8:00 am to 18:00 pm, and the rest time is from 0:00 am to 6:00 am. The network management system can collect the historical and statistical information of the traffic volume of the base station cloud every day, and obtain the historical statistics of the traffic volume. Based on this, the network management system can calculate the best "energy saving start time" and "energy saving". End time", generate energy saving time parameters.

In addition, the energy saving time parameter can also be configured by the user.

S5022, the resource scheduler starts a cyclic scan timer.

S 5023. The resource scheduler determines whether the cyclic scan timer times out.

For example, if the timing time of the cyclic scan timer is set to 5 seconds, if the timing of the cyclic scan timer exceeds 5 seconds, step S5034 is performed.

S5024. The resource scheduler obtains baseband resource usage information on the N baseband processing units with a "powerable" flag.

Where N is a natural number. S 5 02 5. The resource scheduler determines, according to the baseband resource usage information, whether the baseband processing unit is in an idle state.

If yes, step S 5 026 is performed, and if no, step S 5 027 is performed.

S 5 02 6. The resource scheduler performs a power-off operation on the baseband processing unit. For example, if N is equal to 1, the resource scheduler obtains baseband resource usage information on a baseband processing unit with a "powerable" flag when the cyclic scan timer satisfies the time threshold, according to the baseband resource usage information. It is determined that the baseband processing unit is in an idle state, and the power of the baseband processing unit is turned off, thereby achieving energy saving.

S 5 02 7 , the resource scheduler determines whether all baseband processing units with a "powerable" flag have been scanned.

If not, looping through steps S 5 024 to S 5 026 until all baseband processing units with the "power-down" flag are scanned; if yes, performing steps S 5 028 through S 5 0 30, ending Process.

S 5 02 8. The resource scheduler obtains the exchange resource usage information on the switching unit with the “powerable” flag according to the timing time of the cyclic scan timer.

S 5 02 9. The resource scheduler determines an exchange unit in an idle state according to the exchange resource usage information, and performs a power-off operation on the exchange unit.

S 5 0 3 0 , the resource scheduler determines whether all switching units with the "powerable" flag are scanned.

If not, the process proceeds from step S 5 028 to step S 5 0 30 until all the switching units with the "power-off" flag are scanned, and the process ends. If yes, end the process.

In addition, the resource scheduler may deactivate the pair of dynamic cells in the foregoing manner in a non-preset energy saving period. If the dynamic cell does not reach the deactivation threshold in the preset energy saving period , the resource scheduler can pass the above The mode 2 and the mode 5 process the dynamic cell, so that the dynamic cell releases the occupied baseband resource, and performs energy-saving processing on the baseband processing unit and the switching unit corresponding to the dynamic cell by using the foregoing method.

The status identifier corresponding to each baseband resource is set in the centralized baseband pool. When the baseband resource is allocated to the cell, the status identifier corresponding to the baseband resource indicates that the baseband resource is in a busy state. At this time, the resource scheduler cannot The baseband resource is allocated to other cells. When the baseband resource is not allocated, the status indicator corresponding to the baseband resource indicates that the baseband resource is in a free state. At this time, the resource scheduler may allocate the baseband resource to the cell. In this way, when the traffic of the cell decreases and decreases to the threshold of cell deactivation, the resource scheduler deactivates the cell, and changes the state identifier of the baseband resource allocated to the cell from busy to free. , complete the return of the baseband resource to the centralized baseband pool.

The following describes the mode 1 to mode 5:

For example, FIG. 4( a ) is a schematic diagram of a base station cloud allocating baseband resources to a cell in a non-predetermined power saving period. The accessing base station VBTS-A has two cells, where CELL-A1 is a coverage area, and is deployed in The baseband processing unit BBU1 with the "non-power-off" flag; CELL-A2 is a dynamic cell, deployed on the BBU3 with the "power-down" baseband processing unit, and a topology path needs to be established with the RRU1 through the switching unit. There are two cells in the access base station VBTS-B, where CELL-B1 is a coverage area and is deployed on the BBU2 with the "unpowerable" baseband processing unit; CELL-B2 is a dynamic cell, deployed with "可可" Power off the baseband processing unit BBU5 and establish a topology path with the RRU2 through the switching unit.

Using the technical solution of the present invention, a schematic diagram of the centralized baseband pool allocating baseband resources to the cell in a preset energy saving period is shown in FIG. 4(b). The access base station VBTS-A has a cell CELL-A1, wherein the CELL-A1 is a coverage area, and is deployed in the band. There is a "unpowerable" mark on the baseband processing unit BBU1. There are two cells accessing the base station VBTS-B, where CELL-B1 is a coverage area and is deployed on the baseband processing unit BBU2 with the "unpowerable"flag; CELL-B2 is a dynamic cell, deployed with The "can be powered down" marked baseband processing unit BBU1, and a topology path needs to be established with the RRU1 through the switching unit.

In another possible implementation manner of the embodiment of the present invention, the traffic volume of the VBTS-A coverage area is reduced, but the traffic volume of the CELL-A2 deactivation is not reached, and the energy saving time period is reached. The user of CELL-A 2 switches to CELL-A 1 and prohibits new services from being accessed in CELL-A2. When the CELL-A2 service is further degraded and reaches the CELL-A2 deactivated traffic threshold, the CELL-A2 can be automatically deactivated, the baseband resources on the BBU3 are released, and the BBU3 can be idle after the BBU3 is idle. The BBU3 is powered off.

In another possible implementation manner of the embodiment of the present invention, although the traffic volume of the VBTS-B coverage area is reduced, but the traffic value of the CELL-B2 deactivation is not reached, the CELL-B2 still needs to use the baseband resource. . When the preset energy-saving period is reached, the resource scheduler first activates CELL-B2, and the baseband resource of BBU5 occupied by CELL-B2 is released. Release; then activate CELL-B2, at which point CELL-B2 will re-apply baseband resources on the baseband processing unit with "unpowerable", such as BBU1. At this time, the BBU5 can be powered off, and the switching unit that does not undertake other topology path switching can also be powered off. In this scenario, although the number of baseband resources used is not reduced, since the baseband resources to be used are concentrated on the baseband processing unit with the "unpowerable" flag, the baseband resource utilization is improved, and the build extension is reduced. The number of exchange units required for the Park path can therefore achieve the purpose of energy saving.

In this way, the resource scheduler allocates the baseband resources on the baseband processing unit with the "power-down" flag to the dynamic cell, and allocates the baseband resources on the baseband processing unit with the "non-power-off" flag to the coverage area. After the dynamic cell is deactivated, the power-off operation is performed on the baseband processing unit in the idle state, thereby achieving the purpose of energy saving of the device. In addition, the embodiment of the present invention can also implement the switching unit that does not participate in data exchange. The power-off operation further enhances the energy-saving effect of the equipment. The embodiment of the present invention provides a resource scheduler 60.
