Specific embodiment

The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.It should be appreciated that described herein Specific examples are only used to explain the present invention, is not intended to limit the present invention.

As known to those skilled in the art, it under centralized RAN framework, needs to dynamically adjust base there are two types of situation The process resource stood: one is some virtual base station in processor loads and increases, and the processing capacity of the processor cannot The demand after its load increases is fully met, i.e., enough process resources can not be provided;The second is being created in some processor New virtual base station, and the processing capacity of the processor cannot fully meet the demand of new virtual base station load processing.Ying Li Solution, it may be the change of accessed user's business or new user in the network covered by base station that virtual base station load, which increases, The increase of business and caused by.

For former, need to move to the virtual base station other processing for being capable of providing enough process resources Device;And for latter, need to create the new virtual base in the processor that other are capable of providing enough process resources It stands.

According to one embodiment of present invention, the process resource dynamic debugging system under a kind of centralization RAN framework is provided. Fig. 1 shows the overall architecture of the process resource dynamic debugging system, and in short, which includes virtual base station, resource clothes Business device, Resource Server internal processing resource adjust process resource adjustment device between device, Resource Server, in Resource Server Portion's residue process resource distribution list, global resource server residue process resource distribution list and processing resource allocation device. Wherein, for the Resource Server of process resource dynamic adjustment to be carried out, device is adjusted by Resource Server internal processing resource The processor for migrating or creating virtual base station is found first inside the Resource Server, then if there is suitable processor The migration or creation of virtual base station are carried out inside the Resource Server by Resource Server internal processing resource adjustment device; It is provided if without suitable processor by being handled between Resource Server internal processing resource adjustment device notice Resource Server Source adjusts device, suitable processor is found in other Resource Servers by the latter, to carry out between Resource Server The migration or creation of virtual base station.Separately below these components are unfolded to describe:

One, virtual base station

As known to those skilled in the art, be packaged by the base station process resource to physical centralization it is abstract, can Refinement simulates the complete virtual base station system of multiple logic functions.Wherein, the process resource between virtual base station can be dynamically total to It enjoys, virtual base station can generate and cancel on demand, and virtual base station system external provides the mode serviced and true hardware base station Systems compliant.

Two, Resource Server

Resource Server can be based on open platform, have certain processing capacity, and can support multiple base stations wherein The equipment of operation.One Resource Server can support the base station in certain area coverage, the money being made of one group of Resource Server Source server cluster can support all base stations in large area.In one embodiment, Resource Server can be one Generic server with stronger processing power comprising one or more processors, wherein each processor can run one Or multiple virtual base stations.

Three, processing resource allocation device

Process resource needed for processing resource allocation device can distribute its load in advance for each virtual base station, according to load Virtual base station is mapped on some Resource Server by situation.

Four, Resource Server internal processing resource adjusts device

In short, Resource Server internal processing resource adjustment device can control some Resource Server to run virtual Base station is migrated between each processor inside the Resource Server, and is controlled new virtual base station and taken in the resource Creation inside business device is adjusted with completing the process resource dynamic inside Resource Server.In one example, each resource clothes Being engaged in device can be corresponding with a Resource Server internal processing resource adjustment device, for example, Resource Server inter-process provides Source, which adjusts device, to be located in corresponding Resource Server.

In one embodiment, Resource Server internal processing resource adjustment device can monitor in corresponding Resource Server The load variation of the virtual base station of each processor operation.When monitoring to need to migrate some virtual base station or in another processing When device creates new virtual base station, which first can be surplus inside the corresponding Resource Server of the Resource Server by inquiring Remaining process resource distribution list is found and currently meets this virtual base station that migrate or create with the presence or absence of remaining process resource The processor of load, there are two types of possible situations:

If there is such processor, then as the migration target of virtual base station or creation target, then by Resource Server internal processing resource adjusts the migration or creation that device completes virtual base station.Wherein, this virtual base station moves It moves and is also known as the adjustment of virtual base station One Direction Transfer formula.

If there is no such processor, then Resource Server internal processing resource adjustment device continues in the resource Server internal based on above-mentioned list find can by by the virtual base station of self-operating move to other processors so as to The processor of enough process resources (meeting above-mentioned virtual base station load) is enough provided, there are following two situations:

If 1., find such processor, the process resource adjustment inside Resource Server, i.e. resource can be carried out Server internal process resource adjusts device and the virtual base station that the processor is run is moved to other processors, and completes State the migration or creation of virtual base station.

If 2., do not find such processor, Resource Server internal processing resource adjustment device can notify resource Process resource adjusts device between server, carries out the process resource dynamic between Resource Server by the latter and adjusts.

In the present embodiment, as described above, if there is no remaining process resource satisfactions to migrate inside Resource Server Or the processor of the virtual base station load of creation, then the processor for meeting the following conditions is found inside Resource Server: I.e. if one or more virtual base stations that the processor is run move to other processors, the remaining processing money of the processor Source is sufficiently used for carrying out the migration or creation of virtual base station.In a further embodiment, the virtual base station to be migrated is come It says, the maximum processor of remaining process resource can be found inside the Resource Server or finds any one processor. If there are the loading demands of some virtual base station to be less than the demand before the virtual base station to be migrated load increases in the processor With the sum of the remaining process resource of processor where the virtual base station to be migrated, and the loading demand of the virtual base station with The sum of remaining process resource of processor where the virtual base station is greater than the demand after the virtual base station to be migrated load increases, The virtual base station can be then interchangeable with the virtual base station migrated is needed, to complete the processing money inside Resource Server Source adjustment.Wherein, the migration of this virtual base station is also known as the two-way migration formula adjustment of virtual base station.

In the present embodiment, surplus in the Resource Server internal processing resource adjustment each query resource server internal of device It, can be further if finding multiple processors all can serve as to migrate or create target when remaining process resource distribution list Decision is to which processor is migrated or is created.In a further embodiment, can be become according to the current load of processor Change degree is selected.The load variation degree C of processor indicates that within the time of nearest one section of regular length, the processor is sent out The overhead of raw process resource dynamic adjustment, calculation formula are as follows:

C=nadd*add_load+ncreate*create_load

Wherein naddAnd ncreateIt is illustrated respectively in the time of nearest one section of regular length, increases since virtual base station loads The number and lead to the processor due to creating new virtual base station that the process resource dynamic for causing the processor to carry out adjusts The number of the process resource adjustment of progress, add_load and create_load respectively indicate both and adjust spent expense. As it can be seen that processor is more in the number that it participates in process resource dynamic adjustment for the previous period, then it is bigger to load variation degree.Such as Virtual base station is migrated or is created to this processor then again and can further cause stress to the dynamic adjustment of its process resource by fruit, because This should select the load lesser processor of variation degree as migration target or creation target as far as possible.

In one embodiment, the load of each processor in the Resource Server can be regularly calculated by Resource Server Variation degree C.

In a further embodiment, if the load variation degree C of some processor is more than certain threshold values D or length Time is more than certain threshold value, illustrates that it is facing or will continue to occur continuous process resource dynamic and adjusts, then can be by The corresponding Resource Server internal processing resource adjustment device of the processor carries out pre-setting operations.Pass through pre-adjustment process resource Multiple virtual base stations in the processor are moved into other processors, so that the remaining process resource of the processor is sufficiently large To reduce the multiple process resource being likely to occur later adjustment.For example, the processing money that setting needs to pre-allocate for the processor Source size Wpre, that is, needing to create a load on this processor is WpreVirtual base station, can will lead at this The reason device load higher several virtual base stations changed greatly that load of variation degree in itself move to other processors, to complete Pre-adjustment.The processor in Resource Server can be moved to first, if can be used as in the Resource Server without processor Target is migrated, then corresponding Resource Server internal processing resource adjustment device can notify process resource between Resource Server to adjust One or more virtual base stations are moved to the processor in other Resource Servers by the latter by device, to complete processing money The pre-adjustment in source.

Five, process resource adjusts device between Resource Server

Generally, it adjusts and needs to other when process resource dynamic can not be carried out inside some Resource Server When the processor migration or creation virtual base station of Resource Server, process resource adjustment device controls virtual base between Resource Server Stand between the processor for belonging to different resource server carry out virtual base station migration or creation, with complete Resource Server it Between process resource dynamic adjust.Process resource adjustment device can be responsible for the clothes of all resources in system between one Resource Server Business device can monitor the virtual base station load of all processors operations in Resource Server.

In one embodiment, when between Resource Server process resource adjustment device receive by inside Resource Server When reason resource adjustment device is sent, instruction needs to migrate or creates the notice of virtual base station, which inquires the overall situation first Resource Server residue process resource distribution list, searching, which currently meets this with the presence or absence of remaining process resource, will migrate or create The processor for the virtual base station load built.There are following two situations:

If there is such processor:, then can be by the processing the case where for such processor is found Migration target or creation target of the device as virtual base station are then carried out by process resource adjustment device between Resource Server virtual The One Direction Transfer formula of base station adjusts or the creation of new virtual base station;The case where for multiple such processors are found, then Therefrom select a processor as the migration target of virtual base station or creation target, then by process resource between Resource Server Adjust the adjustment of One Direction Transfer formula or the creation of new virtual base station that device carries out virtual base station.

In one embodiment, the processor in the load the smallest Resource Server of variation degree may be selected.Here, resource The load variation degree C of servertotalIt can be the sum of the load variation degree C of all processors in the Resource Server.

If there is no such processor, then process resource adjustment device takes in all resources between Resource Server It is engaged in finding one based on global resource server residue process resource distribution list in device (different from original Resource Server) Processor, so that after one or more virtual base stations that the processor is run move to other processors, the processor Remaining process resource is sufficiently used for carrying out process resource dynamic adjustment.There are two types of situations:

If 1., find such processor, the process resource adjustment between Resource Server, i.e. resource can be carried out One or more virtual base stations that process resource adjustment device runs the processor between server move to other processors, and And complete migration or creation of the above-mentioned virtual base station between Resource Server.

If 2., do not find such processor, process resource adjustment failure.

Similarly, in the present embodiment, if all there is no remaining process resource satisfactions to want in all Resource Servers The processor of the virtual base station of migration or creation load, then find the processor for meeting the following conditions: if by the processing One or more virtual base stations of device operation move to other processors, and the remaining process resource of the processor is sufficiently used for carrying out The migration or creation of virtual base station.In a further embodiment, remaining process resource can be selected in other Resource Servers Maximum processor or any one processor are wanted if the loading demand of a virtual base station of processor operation is less than The remaining process resource of demand before the virtual base station load increase of migration and the processor where the virtual base station to be migrated The sum of, and the sum of remaining process resource of processor where the loading demand of the virtual base station and the virtual base station is greater than need Demand after the virtual base station to be migrated load increase can then carry out the virtual base station and the virtual base station for needing migrate mutual It changes, i.e. the two-way migration formula adjustment of completion virtual base station.Similarly, it if finding multiple processors for meeting condition, may be selected negative Carry the processor in the smallest Resource Server of variation degree.

In one embodiment, as described above, when Resource Server internal processing resource adjustment device carries out processing money When the pre-adjustment of source, for the pre-adjustment that can not be completed inside Resource Server, process resource adjusts device between Resource Server Process resource pre-adjustment can be carried out between Resource Server, including the virtual base station migration between Resource Server.

Six, remaining process resource distribution list inside Resource Server

Remaining process resource distribution list is used to record the sky of each processor in Resource Server inside Resource Server The situation of not busy process resource, a remaining process resource distribution list in Resource Server inside can be opposite with a Resource Server (such as in the Resource Server) is answered, safeguards the remaining process resource of each processor in the Resource Server.The list Device can be adjusted by the Resource Server internal processing resource of corresponding resource server to be managed, carrying out Resource Server For carrying out reference when internal processing resource dynamic adjusts.

Remaining process resource distribution list can be with the virtual base station run in corresponding resource server inside Resource Server Load variation be updated.In one embodiment, when virtual base station load increase, reduction, virtual base station are created or taken When disappearing, renewable resources server internal residue process resource distribution list.For example, any to lead to virtual base station load drop When the case where low or virtual base station is cancelled occurs, the recycling of process resource will do it, be converted into remaining process resource, therefore need The remaining process resource distribution list in Resource Server inside is updated to increase this part of process resource.

In one embodiment, in the initial static for carrying out process resource by certain process resource primary distribution method After distribution, the mapping relations of each virtual base station and Resource Server can be determined, so as to by the processing of each processor Resource distributes to that different size of one or more are virtual according to the loading demand of each virtual base station on Current resource server Base station.Such as when having mapped virtual base station a, b, c on some processor, then during system operation at any time, the processing The value of the remaining process resource R of device are as follows:

R=Wcap–(Wa+Wb+Wc)

Wherein WcapFor the processing capacity that the processor can be provided, and Wa、Wb、WcRespectively 3 virtual base stations it is current Load.

It is concluded and is summarized by the remaining process resource to all processors in Resource Server, it can obtained Distribution of the remaining process resource on each processor in Current resource server, i.e., each processor works as in Resource Server Preceding residue process resource, so as to form remaining process resource distribution list inside Resource Server.

Seven, global resource server residue process resource distribution list

Global resource server residue process resource distribution list safeguards the surplus of each processor in all Resource Servers Remaining process resource follows the load of each virtual base station to change and is updated.For example, at Resource Server inside residue It manages the update of resource distribution list and updates.By adjusting device to all Resource Servers by process resource between Resource Server Inside residue process resource distribution list summarized, global resource server residue process resource distribution list can be formed. Process resource adjustment device can manage the table between Resource Server, for when carrying out the process resource adjustment between Resource Server Carry out reference.

According to one embodiment of present invention, the process resource dynamic adjustment side under a kind of centralization RAN framework is also provided The step of method, Fig. 2 shows this method.

Generally, this method comprises: for process resource adjustment to be carried out (that is, the virtual base station of some processor is negative Carry increase or to create new virtual base station, and current processor can not provide enough process resources) process resource set Standby (it includes one or more processors, Resource Server as described above), can be first inside the process resource equipment Another processor is found as migrating or creating target, to carry out process resource adjustment;If do not looked for inside the equipment To that can be used as migration or create the processor of target, then then reason resource apparatus finds a processor to carry out in the outside Process resource adjustment.Wherein, either inside equipment or in outside, can first look for remaining process resource can be enough into Row migrates and creates the processor of virtual base station to carry out process resource adjustment;If continually looked for without such processor It can be sufficient for migrating and creating the processing of virtual base station by the way that the virtual base station of itself is moved to other processors Device.

There is the situation for needing dynamic to adjust process resource in the first step.

As described above, when some virtual base station load in processor increases and the processing capacity of the processor cannot When fully meeting the demand after its load increases, and works as and create new virtual base station and the processor in some processor Processing capacity when cannot fully meet new virtual base station loading demand, need to adjust process resource.

Second step determines the processor (migration/creation target) that virtual base station will be migrated/be created, and carries out virtual base station Migration/creation.

Resource Server described herein above respectively carries out the migration of virtual base station and creation as process resource equipment Description:

1, is loaded for virtual base station the case where increasing, the adjustment of process resource includes following sub-step:

Process resource dynamic inside step 1), Resource Server adjusts.
