Embodiment
The embodiment of the invention provides a kind of inter-frequency networking method and device of different time-gap proportioning; With cross time-slot all or part of distribute to up link or down link; Owing to comprise a large amount of orthogonal sub-carriers in each time slot, and resource allocation is that sub carrier group is that unit distributes, so can add up the operating position of up-downgoing resource; Acquisition exists this sub-district of cross time-slot and the concrete resource requirement of neighbor cell; Carry out dynamic resource allocation according to concrete resource requirement again, and then avoided the interference of cross time-slot, and made full use of the resource of cross time-slot.
Generally in TDD OFDMA, each time slot has all comprised a large amount of orthogonal sub-carriers, and resource allocation to be unit with the sub carrier group distribute, such as the resource among the LTE fast (RB).Based on these distribution characteristics; Can be when system initialization; At separated into two parts physically, the sub-district of each different time-gap proportioning adopts a part wherein to carry out up or downlink data transmission respectively, then in the statistics of regularly carrying out the uplink and downlink RB resource operating position in the certain hour respectively with the cross time-slot of different time-gap proportioning networking; Result according to statistics; Carry out reconfiguring of cross time slot resource, make the use of cross time slot resource can adapt to the professional demand of up-downgoing, improve the capacity of sub-district.
As shown in Figure 1, the inter-frequency networking method of the different time-gap proportioning that the embodiment of the invention provides comprises the process of redistributing cross time slot resource, and this process comprises:
Step S101, when satisfying resource and redistribute condition, confirm this local resource operating position in the timing statistics length;
Step S102, obtain the resource operating position in this timing statistics length that neighbor cell is confirmed, usually, because that the resource of setting is redistributed condition is identical, so neighbor cell statistics resource operating position is added up with this cell synchronizing;
Step S103, according to the resource operating position of this local resource operating position and neighbor cell, redistribute the resource of cross time-slot.
In step S101, resource is redistributed condition and is generally the time cycle that reaches setting, under special circumstances, can redistribute order through the transmission resource and redistribute resource, and at this moment, resource is redistributed condition and redistributed order for receiving resource.
In practical operation, can be according to the rational setting-up time of the actual conditions cycles such as size of the scale and the traffic carrying capacity of sub-district, the time cycle is hour; The frequency of redistributing cross time slot resource is just bigger; And then improve the capacity of sub-district, but frequent statistics, mutual and adjustment also can constitute certain burden to the network equipment, and the time cycle is when big; The frequency of redistributing cross time slot resource is just less; Because the traffic carrying capacity of sub-district may change,, may cause certain wasting of resources if can not in time adjust.So when reality was used, can set according to actual conditions and use experience should the time cycle, thus preferable adjustment effect.
When initial networking, also comprise the process of allocating cross time slot resource in advance, for preventing to disturb; Can obtain the time slot configuration information of neighbor cell earlier; Confirm the position of cross time-slot in frame structure,, distribute the resource of cross time-slot again according to predefined original allocation ratio.For example; Can the resource of cross time-slot all be used for this sub-district or all be used for neighbor cell; Also can be according to the resource of this cross time-slot of pro rate of 1: 1; Certainly can also set the ratio of original allocation according to actual conditions and experience, and according to the resource of this pro rate cross time-slot.
In step S101, the method for adding up this local resource operating position has multiple, for example:
When this sub-district uses cross time slot resource to carry out uplink service:
Can obtain uplink service request or the Resource Block number of actual allocated and the number of the interior sub-frame of uplink of timing statistics length in the timing statistics length, and with the ratio of the number of the Resource Block number of uplink service request or actual allocated and the sub-frame of uplink resource operating position as this sub-district; Also can obtain uplink service request or the Resource Block number of actual allocated and the number of the interior ascending time slot of timing statistics length in the timing statistics length, and with the ratio of the number of the Resource Block number of uplink service request or actual allocated and the ascending time slot resource operating position as this sub-district;
When this sub-district uses cross time slot resource to carry out downlink business:
Can obtain downlink business request or the Resource Block number of actual allocated and the number of the interior descending sub frame of timing statistics length in the timing statistics length equally, and with the ratio of the number of the Resource Block number of downlink business request or actual allocated and the descending sub frame resource operating position as this sub-district; Also can obtain downlink business request or the Resource Block number of actual allocated and the number of the interior descending time slot of timing statistics length in the timing statistics length, and with the ratio of the number of the Resource Block number of downlink business request or actual allocated and the descending time slot resource operating position as this sub-district.
Usually, when traffic carrying capacity is little, add up to get final product through the Resource Block number of actual allocated; But when traffic carrying capacity is very big; Possible all Resource Block all are used, and at this moment, add up through requested resource piece number and can better reflect the conditions of demand of this sub-district to resource.
Generally; One of this sub-district and neighbor cell carry out uplink service, and another carries out downlink business, and employed statistical method all is identical; For example this sub-district is with the ratio of the number of uplink service requested resource piece number and the sub-frame of uplink resource operating position as this sub-district; Neighbor cell is just accordingly with the ratio of the number of downlink business requested resource piece number and the sub-frame of uplink resource operating position as this sub-district, under special circumstances, if this sub-district of existence and the employed statistical method condition of different of neighbor cell; Can obtain neighbor cell after the statistics of the resource operating position of this time cycle, processing converts.At first can be according to the information such as unit in the statistics of resource operating position; Confirm the statistical method of the resource operating position of neighbor cell, judge further more whether the employed statistical method of neighbor cell is identical with this sub-district, if identical; Then can directly use the statistics that is obtained; If inequality, then the statistics of neighbor cell in the resource operating position of this time cycle converted, be scaled the numerical value identical with this sub-district statistics unit.
In step S103; Resource operating position according to this local resource operating position and neighbor cell; Redistributing the mode of the resource of cross time-slot can set according to actual conditions equally; Certainly according to this sub-district and neighbor cell to the demand of resource, the resource of cross time-slot is distributed to the sub-district more to resource requirement as far as possible, and then the utilance of raising resource.
A kind of fair method of salary distribution is: the ratio of resource operating position of confirming resource operating position and this sub-district of neighbor cell; And redistribute the resource of cross time-slot according to this ratio; Dynamic like this, the adaptive resource of cutting apart this cross time-slot can the maximize resource utilance.Certainly, also can all give certain sub-district and use, for example, the resource of cross time-slot all distributed to neighbor cell when the resource operating position of neighbor cell during greater than the resource operating position of this sub-district with the resource of cross time-slot; When the resource operating position of neighbor cell during, the resource of cross time-slot is all distributed to this sub-district less than the resource operating position of this sub-district; When the resource operating position of the resource operating position of neighbor cell and this sub-district is identical, the resource of cross time-slot is all distributed to the higher sub-district of service priority in this sub-district and the neighbor cell.Concrete divide timing, can be behind the ratio of the resource operating position of the resource operating position of confirming neighbor cell and this sub-district, when ratio greater than 1 the time; The resource of cross time-slot is all distributed to neighbor cell, when ratio less than 1 the time, the resource of cross time-slot is all distributed to this sub-district; When ratio equals 1; Carry out the resource allocation of cross time-slot according to service priority,, then the resource of cross time-slot is all distributed to this sub-district if the service priority of this sub-district is higher; If the service priority of neighbor cell is higher; Then the resource of cross time-slot is all distributed to neighbor cell, dynamic like this, the adaptive cross time-slot that uses in turn then can be eliminated cross time-slot fully and disturb.
The inter-frequency networking method of the different time-gap proportioning that the embodiment of the invention provides is described with a concrete embodiment below, as shown in Figure 2, begin from initial configuration, this network-building method comprises:
Step S201, obtain the time slot configuration information of neighbor cell;
Step S202, judge whether neighbor cell has adopted the time slot proportion different with this sub-district, if then continue execution in step S203, otherwise process ends;
The time slot proportion of step S203, comparison neighbor cell and this sub-district is confirmed the position of cross time-slot in frame structure.
As shown in Figure 3; Frame structure with TDD LTE is example (but the present invention is not limited only to TDD LTE standard); Because sub-district A adopted DL: UL=2: 3 time slot proportion, sub-district B adopts DL: UL=3: 2 time slot proportion, thus confirmed the position of cross time-slot; Cross time-slot appears at the 5th sub-frame and the 10th sub-frame place, and a cross time-slot promptly appears in per 5 sub-frame.
Step S204, according to predefined original allocation ratio, cross time-slot is carried out the initialization resource allocation.
Such as all RB resources of cross time-slot are divided half-and-half, cross time-slot place neighbor cell adopts wherein half respectively.As shown in Figure 4, with the resource of cross time-slot distributing according to frequency domain 1: 1.Can certainly carry out the initialization division of resources of arbitrary proportion as the case may be with empirical value, even can the resource of this cross time-slot all be used for the uplink service of a sub-district or all be used for the downlink business of a sub-district.
In addition, for reducing the interference of adjacent time-slots, can be when scheduling of resource according to the actual conditions priority scheduling from the distant Resource Block of up-downgoing cut zone.Perhaps in scheduling, just consider certain resource isolation, as shown in Figure 3, between the up-downgoing resource of being distributed, the isolation strip is set.
Step S205, carry out timing, when arriving predefined time cycle, execution in step S206; Add up in real time if desired and adjust, perhaps this time cycle is set to 0 can to skip this step.
Step S206, according to predefined timing statistics length, in this timing statistics length, carry out the statistics of resource operating position.Such as; The request of statistics different business RB number in this timing statistics length respectively of sub-district, cross time-slot place; The RB number of the professional sub-district statistics downlink business request of bearing downlink on cross time-slot is carried the RB number of the sub-district statistics uplink service request of uplink service on cross time-slot, then respectively divided by the number of up in this timing statistics length or descending time slot; Obtain the number of the request of RB on each time slot, that is:
The resource operating position of carrying the sub-district of uplink service is: the ratio of the number of ascending time slot in the RB number of uplink service request and this timing statistics length in the whole timing statistics length; The i.e. RB of average each ascending time slot request number; The resource operating position of the sub-district that bearing downlink is professional is: the ratio of the number of descending time slot in the RB number of downlink business request and this timing statistics length in the whole timing statistics length, the i.e. RB of average each descending time slot request number.
Certainly; The RB request number that also can each sub-frame of uplink of statistical average and the RB request number of average each descending sub frame; Perhaps the RB actual allocated number of each sub-frame of uplink of statistical average and on average the RB actual allocated number of each descending sub frame, the RB actual allocated number of the RB actual allocated number of all right each ascending time slot of statistical average and average each descending time slot.
Timing statistics length can be provided with as the case may be, such as being set to 50ms, just 5 LTE frames is added up.
Concrete, be example still with TDD LTE frame structure.If the timing statistics length setting is 10ms, promptly a TDD LTE radio frames is as shown in Figure 3; Sub-district A adopts DL: UL=2: 3 time slot proportion; Sub-district B adopts DL: UL=3: 2 time slot proportion, cross time-slot appear at the 5th and the 10th sub-frame, 2 time slots of each subframe.This cross time-slot is used for uplink among the A of sub-district; Then sub-district A adds up the RB number of uplink service request; And in the whole timing statistics length, sub-district A has 6 sub-frame of uplink, totally 12 ascending time slots; So among the A of sub-district on average each ascending time slot the request number of RB be: the ratio of ascending time slot number in the RB number of the uplink service request in the whole timing statistics length and the whole timing statistics length, RB number/12 of the uplink service request that promptly whole timing statistics length is interior.
Correspondingly; B is used for downlink transfer to cross time-slot in the sub-district; Then the RB number of downlink business request is regularly added up in this sub-district; And in the whole timing statistics length, sub-district B has 6 descending sub frames, totally 12 descending time slots; So among the B of sub-district on each descending time slot the request number of RB be: the ratio of descending time slot number in the RB number of the downlink business request in the whole timing statistics length and the whole timing statistics length, RB number/12 of the downlink business request that promptly whole timing statistics length is interior.
The statistics of the resource operating position of step S207, acquisition neighbor cell.
In the LTE system; The result of statistics is separately intercoursed in sub-district, cross time-slot place; Obtain the other side's statistics information mutually, can realize, can certainly pass through the S1 interface through X2 interface; According to applied system and other actual conditions, can also adopt other interface and exchanged form to intercourse the result of statistics separately.
Concrete; If this cross time-slot of this sub-district is used for downlink transfer; Through X2 interface, this sub-district on average statistics of the RB number of each descending time slot request sends to the neighbor cell that cross time-slot is arranged with it, and neighbor cell has just obtained the statistics of this sub-district like this.Correspondingly, this sub-district has also obtained to have with it the statistics of RB number of average each the ascending time slot request of neighbor cell of cross time-slot through X2 interface.
Step S208, obtain to have with it the statistics of neighbor cell of cross time-slot after, the resource allocation of adjusting cross time-slot according to the resource operating position and the predefined resource allocation rule of this local resource operating position and neighbor cell.
When the resource statistics situation being the RB number of average on each/descending time slot request; This principle can be the ratio according to the RB number of the RB number of each ascending time slot average request and each descending time slot average request; Carry out cross time slot resource ration of division adjustment: if this sub-district bearing downlink is professional, average each ascending time slot RB request number of the adjacent sub-district that this sub-district will obtain through X2 interface asks number to be divided by with average each descending time slot RB that this sub-district oneself statistics obtains, and obtains this cross time slot resource and adds up ratio; Carry out the resource adjustment according to this ratio then; For example: if this ratio is 3, then the band resource with this cross time-slot is adjusted into 3: 1 ratio from original allocation proportion, carries out up-downgoing again according to 3: 1 ratios and carries out division of resources; Promptly according to the result who adds up; Judge that the up business demand of this time slot is bigger, therefore more resources is adjusted into up use, thereby to a certain extent resource utilization is maximized.
Certainly, disturb, can the resource of cross time-slot be distributed to the sub-district bigger to resource requirement fully for eliminating cross time-slot fully; At this moment; In step S204, when initial configuration, according to preset rule; The resource of cross time-slot is all distributed to the professional sub-district of bearing downlink, perhaps all cross time slot resource is all distributed to the sub-district of carrying uplink service; In step S208, after the timing statistics of the neighbor cell that obtains to have with it cross time-slot, adjudicate the resource allocation of adjustment cross time-slot and then be specially: the ratio of the RB number of asking according to the RB number and the descending RB of up RB request according to preestablishing rule; Adjudicate this cross time-slot and distribute to the professional sub-district of bearing downlink or distribute to the sub-district of carrying uplink service, for example, if uplink service is carried in this sub-district; When ratio greater than 1 the time, explain that this sub-district is bigger to the demand of resource, the resource of cross time-slot is all distributed to this sub-district; When ratio less than 1 the time, explain that neighbor cell is bigger to the demand of resource, the resource of cross time-slot is all distributed to neighbor cell; When ratio equals 1; Can also carry out the resource allocation of cross time-slot according to service priority,, then the resource of cross time-slot all distributed to this sub-district if the service priority of this sub-district is higher; If the service priority of neighbor cell is higher, then the resource of cross time-slot is all distributed to neighbor cell.
Accordingly, the embodiment of the invention also provides a kind of identical networking device of different time-gap proportioning, and is as shown in Figure 5, comprising: statistic unit 501, acquiring unit 502 and allocation units 503, wherein:
