Description

A kind of baseband resource managing method, system and device
Technical field
The present invention relates to communication technical field, relate in particular to a kind of baseband resource managing method, system and device.
Background technology
Along with the fast development of mobile communication, people are more and more higher to the requirement of mobile communication, demand is increasing.In order to satisfy customer service better, the capacity of base station is had higher requirement, bring the vacancy rate of base-band resource also constantly to rise thus, cause a large amount of wastes of resource.Simultaneously, the power consumption brought of newly-increased base-band resource also makes operation cost constantly rise.
Prior art adopts the mode of baseband pool to manage base-band resource usually, and base-band resource is no longer fixing to be monopolized by some sub-districts, and can be shared by a plurality of sub-districts.When certain part base-band resource breaks down, can realize redistributing of base-band resource by the carrier wave technology of helping each other, satisfy business demand and recover again, reduced O﹠M cost to a certain extent.
In the common baseband pool Managed Solution, in order to satisfy the capacity requirement of sub-district, each sub-district is generally according to peaking capacity planning base-band resource, thereby the base-band resource that needs is more.Therefore, prior art has proposed morning and evening tides (migratory bird) effect scheme, this scheme is by the analysis to regional traffic matrix, the period of considering certain two regional telephone traffic peak values and low ebb can be complementary, for example Office Area and residential area, daytime, the Office Area traffic was more, so the base-band resource that daytime, the Office Area needed is more, and night, the residential area traffic was more, so the base-band resource that night, the residential area needed is more.Therefore, can redistribute Office Area and uptown base-band resource, improve the utilance of base-band resource to a certain extent in fixing period.But, when adopting this scheme, remain in the set time section of base-band resource before switching and to be monopolized by a sub-district, when accident occurs, this base-band resource often can't satisfy the demands, and can't be adjusted to automatically the sub-district that accident takes place from this sub-district by the base-band resource that another sub-district is monopolized.And whether existing base-band resource no matter bearer service, all is in to work on power.
This shows that existing base band Managed Solution has following shortcoming:
When the mode of employing baseband pool is managed base-band resource, the carrier capacity planning of the division reference cell of base-band resource, in case set up the corresponding relation of base band and sub-district, base-band resource and sub-district are fixing the bindings, even the base-band resource of sub-district binding does not carry the user, still monopolized by this sub-district.During planning in order to satisfy the peak demand of cell business volume, need consider that separately the maximum carrier capacity of overlay area plans by each sub-district, therefore the base-band resource that needs is the stack of the base-band resource of each sub-district, thereby can cause the very big waste of base-band resource.
Morning and evening tides (wait crow) effect scheme is based on the baseband resource managing scheme of frequency between set time point switching cell, if run into accident, such as night the Office Area a large number of services appears suddenly, set time point handover scheme obviously can't satisfy emergent demand.If, strengthened the O﹠M burden undoubtedly again by increasing the emergent problem that solves artificial on duty.This scheme has been considered the inter-cell traffic model complementary, but the assessment of this business model and foundation need done a large amount of research works in early stage, and can not have complete environment to do the foundation of business model before the networking, therefore in fact, the current operation model all can only adopt the method for pre-estimating, and there is certain uncertainty in this estimation, if deviation, design capacity can not be met consumers' demand, and causes user's access rate low easily.So the tidal effect solution has just been considered business model roughly, do not consider in fact whether current frequency really carries the user.
And, also be to be in power-up state though idle base-band resource of the prior art does not have carrying user data, cause energy waste.
In sum, prior art is lower to the utilance of base-band resource.

Embodiment
The embodiment of the invention provides a kind of baseband resource managing method, system and device, in order to realize real-time dynamic management to base-band resource, thereby improve the base-band resource utilance, make that the utilization of base-band resource is more rationally effective, in the face of the bursts of traffic peak time, can effectively avoid the generation of call drop situation.
In the embodiment of the invention, satisfy the customer service demand, and adjust base-band resource automatically, realized base-band resource distribution according to need neatly between different districts along with the variation of customer service with minimum base-band resource; Further, cooperate with corresponding economize on electricity means, thereby farthest reduce the base-band resource energy consumption, avoid the wasting of resources.
Need to prove that home cell described in the embodiment of the invention (LocallCell) and home cell group are the notions of resource capacity.The base station is when setting up sub-district (Cell), need be with reference to home cell, promptly the sub-district is that the basis is set up with the home cell, for example, some home cells have the base-band resource of 6 frequencies, then can adopt the base-band resource of 3 frequencies wherein to set up a sub-district.Home cell and home cell group are many-to-one relations, and home cell and sub-district are man-to-man relations.
All need to store the corresponding relation of home cell and home cell group in RNC and the base station, and the corresponding relation of home cell and sub-district, to realize base-band resource scheduling to Target cell.Wherein, the home cell of RNC side storage and the corresponding relation of home cell group, and the corresponding relation of home cell and sub-district can be disposed by operation maintenance center (OMC).And the corresponding relation of the home cell of base station side storage and home cell group can be disposed by OMC, corresponding relation as for home cell and sub-district, then can set up by RNC, RNC sets up the information of setting up the sub-district on the home cell that is carried at appointment in the request in the sub-district, the sub-district is set up according to this information in the base station, determine the corresponding relation of home cell and sub-district, thereby in the cell configuration process that follow-up RNC initiates, the base station can correspond to Target cell on the home cell of self maintained according to this information.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
Referring to Fig. 1, a kind of baseband resource managing method that the embodiment of the invention provides totally comprises step:
S101, radio network controller (RNC) be user's access amount of monitoring objective sub-district (or claiming designated cell) in real time.
S102, RNC compare user's access amount and predetermined threshold value, and adjust the base-band resource of this little target area according to comparative result control base station.
S103, base station adjust the base-band resource of Target cell according to the control of RNC.
Particularly, step S102 comprises: when user's access amount of Target cell surpassed first predetermined threshold value, base-band resource was distributed for this Target cell in RNC control base station; When user's access amount of Target cell was lower than second predetermined threshold value, RNC control base station discharged the base-band resource of this Target cell; Wherein, described first predetermined threshold value is greater than described second predetermined threshold value.
The business model that the embodiment of the invention inserts according to the user, adopt frequency preset mechanism distribution according to need base-band resource, so in fact, can realize base-band resource dynamically sharing in real time between different districts, reach the purpose that satisfies the customer service demand with minimum base-band resource, thereby avoid in the existing tidal effect scheme should be acute poor, model evaluation is uncertain, the synthesis energy saving effect is low shortcoming.
Described frequency preset mechanism, promptly by predefined first predetermined threshold value, i.e. carrier wave application thresholding guarantees the sub-district before can't satisfying the user admission amount, carrier capacity is replenished in advance; By predefined second predetermined threshold value, promptly carrier wave discharges thresholding, guarantees that the adjustment of cell carrier capacity can be too not frequent.
Provide the specific embodiment explanation below.
Preferably, the embodiment of the invention adopts OMC, RNC and base station (NodeB) three network elements to cooperate the management of finishing base-band resource, and as shown in Figure 2, a kind of baseband resource managing method that the embodiment of the invention provides specifically comprises step:
S201, OMC plan the corresponding relation of corresponding relation, home cell and the home cell group of home cell and sub-district in advance, and predetermined threshold value, be above-mentioned first predetermined threshold value and second predetermined threshold value, and give RNC, preserve in this locality by RNC with these information configuration.The corresponding relation of home cell that OMC will plan in advance again and home cell group disposes to NodeB, is preserved in this locality by NodeB.
Because the corresponding relation of sub-district and home cell is planned in advance by OMC equally and is disposed to RNC, so RNC can extrapolate the corresponding relation of sub-district and home cell group.
A NodeB can safeguard a plurality of home cell groups, the corresponding one or more home cells of each home cell group.The corresponding base band resource pool of each home cell group comprises one or more carrier wave base-band resources in the base band resource pool.The home cell that only is under the jurisdiction of same home cell group could be shared the base-band resource in the base band resource pool of this home cell group correspondence.
S202, NodeB when initial, only set up a frequency to each home cell after starting, and are carrier wave base-band resource of each cell allocation.Then, NodeB notifies the RNC home cell corresponding home cell group ability in the mode of resource status indication.
Wherein, home cell group ability utilizes that home cell group information unit (Local Cell Group Information IE) carries in base station application part (NBAP, the Node B application part) agreement.Under the prerequisite of not destroying the NBAP protocol integrity, the situation of change of home cell group ability is notified to RNC by Local CellGroup Information IE, thereby has realized the real-time update to home cell group ability among the RNC.
Home cell group ability described in the embodiment of the invention, promptly the idle base-band resource amount that is contained in the base band resource pool of home cell group correspondence that is to say to also have how many idle frequencies to distribute in this base band resource pool.
RNC initiates the sub-district according to the planned capacity (being the frequency resource that home cell is planned) of sub-district and sets up, the sub-district that NodeB sends according to RNC is set up request message and is set up the sub-district, if setting up the frequency configuration that comprises in the request message, the sub-district surpasses 1, NodeB will redistribute base-band resource for home cell at the part that exceeds so, promptly set up corresponding frequency for the sub-district again.After the sub-district was set up and finished, NodeB set up the sub-district and finishes message informing to RNC.If home cell group ability changes in this process, NodeB is with the change of resource status indicating mode notice RNC home cell group ability.
The access situation of S203, the real-time monitor user ' of RNC is promptly obtained user's access amount of Target cell in real time.
S204, when RNC finds that user's access amount of a frequency of certain sub-district or a plurality of frequencies surpasses first predetermined threshold value, utilize cell re-configuration to put process notice NodeB and add frequency for this sub-district, be corresponding home cell interpolation base-band resource.
NodeB searches the corresponding relation of pre-configured home cell and home cell group according to the notice of RNC, determines to need to add the pairing home cell group in sub-district of frequency; From the base band resource pool of this home cell group correspondence, choose the idle base-band resource of one or more frequencies, should distribute to this home cell and activate this frequency by the free time base-band resource.After the frequency of finishing designated cell added, NodeB put response message with cell re-configuration and is notified to RNC.And notify home cell group ability after RNC upgrades in the mode of resource status indication, because idle base-band resource tails off, so should this locality home cell group ability diminish.
Further, after the home cell group ability of RNC after receiving renewal, the home cell group ability after this renewal is notified to OMC, so that follow-up Operation and Maintenance.
S205, when RNC finds that user's access amount of one or more frequencies of certain sub-district is lower than second predetermined threshold value, RNC utilizes cell re-configuration to put process notice NodeB discharges one or more frequencies for this sub-district base-band resource.Further, for fear of the situation that conversation loss takes place on frequency to be discharged, RNC can take dynamic channel allocation (DCA) algorithm that the customer service on this frequency is adjusted to other earlier on the clothes frequency before notice NodeB discharges the base-band resource of certain frequency.
NodeB is according to the notice of RNC, for frequency is specified in the designated cell deletion, the base-band resource of this appointment frequency is discharged from the sub-district, and be recovered in the pairing base band resource pool of the pairing home cell group in this sub-district, thereby, idle base-band resource in this base band resource pool becomes many, and it is big that this home cell group ability becomes.And NodeB puts response message notice notice RNC frequency with cell re-configuration and discharges and finish, and notifies home cell group ability after RNC upgrades in the mode of resource status indication.
Further, after the home cell group ability of RNC after receiving renewal, the home cell group ability after this renewal is notified to OMC.
S206, break down when some base-band resource of NodeB itself, when perhaps from fault, recovering, corresponding home cell group ability is upgraded in the capital, therefore, NodeB will give RNC with the home cell group ability real-time informing after upgrading, for RNC reference before the base-band resource scheduling, to guarantee the validity of each scheduling.
That is to say that when the home cell group ability of NodeB self maintained changed, the home cell group ability after will changing immediately was notified to RNC, RNC upgrades corresponding home cell group ability synchronously.RNC is in control before the base station is the cell allocation base-band resource, according to the pre-configured sub-district and the corresponding relation of home cell, and the corresponding relation of home cell and home cell group, determine the pairing home cell group of Target cell; Home cell group ability according to this home cell group correspondence, judge whether current this home cell group ability satisfies the condition of distributing base-band resource for Target cell, that is to say in the base band resource pool of this home cell group correspondence of base station side and whether also have idle carrier wave, if satisfy, then described RNC control base station is this cell allocation base-band resource, otherwise the base-band resource of this sub-district is not dispatched.
Further, electric treatment is descended to the base-band resource that discharges in the base station.It is unit that the base-band resource that the embodiment of the invention proposes is shared with the carrier wave, therefore helps the enforcement of power-saving mechanism.For example, under traffic affecting prerequisite not, cooperation is with the base-band resource allocative decision of compactness, the base station initiatively utilizes the carrier wave mutual-aid function that base-band resource is carried out the compactness arrangement, regular base-band resource fragment, make the digital signal processor (DSP) of processing base band data and the idle quantity of integrated circuit board reach maximum, thereby electricity is tactful down to these idle devices enforcements, farthest saves the required energy consumption of Base-Band Processing.
The effect comparison analysis of adopting prior art and the technical scheme that adopts the embodiment of the invention to provide to reach is provided below.
One, base-band resource takies situation relatively.
With 24 hours subscribers carrier demand of a S4/4 base station whole day is example, and Fig. 3 shows whole day user's telephone traffic curve of first sub-district and second sub-district of a S4/4 BTS management.The technical scheme that the base station adopts baseband pool scheme, tidal effect scheme and the embodiment of the invention of prior art to provide respectively manages base-band resource, and it is as follows that resulting base-band resource takies the situation contrast:
As shown in Figure 4, adopt when having the baseband pool scheme now, first sub-district and the second sub-district whole day all need to take 4 carrier wave base-band resources, and first sub-district and the stack of the second cell carrier demand can be seen that the base station needs to continue to provide in 24 hours the base-band resource of 8 carrier waves.
As shown in Figure 5, when adopting the tidal effect scheme, first sub-district and the second sub-district time-sharing multiplex base-band resource are regularly adjusted the cell baseband capacity by the time model of planning.The carrier wave demand stack of first sub-district and second sub-district can be seen that the base station needs to continue to provide in 24 hours the base-band resource of 6 carrier waves.
As shown in Figure 6, adopt that the embodiment of the invention provides based on the baseband resource managing scheme of business model the time, the cell carrier capacity is adjusted in real time according to business demand in first sub-district and second sub-district.With first sub-district and the stack of the second cell baseband demand, can see occupied base-band resource along with the cell carrier changes in demand, whole day takies the baseband carrier resource of 5 carrier waves at most in 24 hours, and minimum need take the base-band resource of 2 carrier waves.
By above-mentioned 3 kinds of baseband resource managing methods as can be seen, the technical scheme that adopts the embodiment of the invention to provide can effectively be saved base-band resource, improves the base-band resource utilance.Further, at the frequency resource that discharges, the strategy of electricity or frequency reducing can reach remarkable energy saving effect under the NodeB employing processor.
