Embodiment

Embodiments provide method and the device of cooperative arrangement running time-frequency resource between a kind of Home eNodeB, in the embodiment of the present invention, the distributor of running time-frequency resource is called centralized management equipment, by the multiple Home eNodeB of centralized management equipment unified management, in running time-frequency resource pre-provisioning procedure, take the principle of the not multiplexing identical running time-frequency resource in adjacent area, at utmost for administration in Home eNodeB distribute current system can running time-frequency resource, at some service Home eNodeB without available preassignment running time-frequency resource, or preassignment running time-frequency resource is not when meeting present rate demand, judge whether this service Home eNodeB exists running time-frequency resource for subsequent use, this running time-frequency resource for subsequent use is the running time-frequency resource that this service Home eNodeB and neighboring home base station thereof did not all configure in pre-provisioning procedure, if exist, then distribute running time-frequency resource for subsequent use for this service Home eNodeB, if present rate demand can be met after distributing, then terminate this cooperative arrangement, otherwise, continue to judge whether there is pre-configured but untapped running time-frequency resource in the neighboring home base station of this service Home eNodeB, if exist, then this time-frequency resource allocating is used to this service Home eNodeB, and when meeting present rate demand after this service Home eNodeB is assigned with this running time-frequency resource, terminate this cooperative arrangement, if do not exist, or when still not meeting present rate demand after this service Home eNodeB is assigned with this running time-frequency resource, calculate the value of each running time-frequency resource in its adjacent base station, according to value, running time-frequency resource in adjacent base station is transferred the possession of to this service Home eNodeB successively, until this service Home eNodeB meets present rate demand, terminate this cooperative arrangement.After this cooperative arrangement of end, cooperative arrangement result sends to the Home eNodeB that running time-frequency resource variation occurs by centralized management equipment.Like this, by being the running time-frequency resource that the Home eNodeB configuration in region uses in advance, the Signalling exchange between Home eNodeB and common control equipment is reduced while evading interference, by adopting cooperative arrangement running time-frequency resource between Home eNodeB, reduce because Home eNodeB disposes the impact changing and cause peripheral base station, improve the stability of network, reliability and service quality, decrease the cutting off rate of signaling consumption and switching, effectively reduce the variation of resource allocation result to the impact of network operation stability.

Below in conjunction with Figure of description, the preferred scheme of the embodiment of the present invention is elaborated.

In the embodiment of the present invention, as shown in Figure 1, centralized management equipment is connected with Home eNodeB by return network the network architecture of centralized management equipment, and through femto gateway core network access.Wherein, a centralized management equipment can be connected with multiple Home eNodeB, manages multiple Home eNodeB simultaneously, and the quantity of the maximum ALARA Principle Home eNodeB of a centralized management equipment determines according to the memory capacity of centralized management equipment and arithmetic speed.One family base station is only connected with a centralized management equipment.Preferably, the time-frequency distribution method of embodiment of the present invention design is for enterprise-level time-division Long Term Evolution (TimeDivisionLongTermEvolution, TD-LTE) Home eNodeB.

In prior art, Home eNodeB has the high deployment degree of freedom, dispose the honeycomb distributed model not meeting macro base station, cause the wireless distribution method of time frequency resources (as spectrum reuse etc.) being applicable to macro base station can not be applicable to the wireless time-frequency resource allocating of Home eNodeB well.In addition, user may switching on and shutting down at any time or change the installation site of Home eNodeB, cause the variation that Home eNodeB is disposed.No matter be Virtual network operator or user, all wish that the deployment of Home eNodeB changes the Radio Resource caused and redistributes the impact of network operation situation little as much as possible, therefore, the embodiment of the present invention proposes the method for the wireless running time-frequency resource of a kind of self-adjusted block, realize the interference coordination schemes being applicable to Home eNodeB scene, and scheme can be reconfigured according to Home eNodeB deployment variation adaptively.

Particularly, in the embodiment of the present invention, the running time-frequency resource of centralized management equipment to the Home eNodeB in administration carries out unified management and distribution, and consult shown in Fig. 2, the pre-configured flow process for Home eNodeB running time-frequency resource is as follows.

Step 200: centralized management equipment is according to the neighbouring relations between each Home eNodeB, and the current available running time-frequency resource sum of system, determines the running time-frequency resource number that each Home eNodeB can configure at most.

Particularly, centralized management equipment is by the Home eNodeB in administration, and covering area overlapping or adjacent base station are set to adjacent base station.Determine that the method for the running time-frequency resource number that any one Home eNodeB can configure at most is: the number of the neighboring home base station of any one selected Home eNodeB is added one, obtain the allocation base of this Home eNodeB, by current for system available running time-frequency resource sum divided by the allocation base obtained, and the quotient obtained is rounded downwards, obtain the running time-frequency resource number that this Home eNodeB can configure at most.

Such as, the adjacent base station number of base station A is 3, and the current available running time-frequency resource of system adds up to 10, then in this, the running time-frequency resource number that all base stations in centralized management equipment can being administered can configure at most calculates.

Step 210: the running time-frequency resource number that can configure at most according to each Home eNodeB, is followed successively by the running time-frequency resource of each Home eNodeB configuration respective number, wherein, and any two adjacent not multiplexing identical running time-frequency resources in base station.

The running time-frequency resource number that each Home eNodeB can configure at most is calculated according to the method described in step 200, be followed successively by the running time-frequency resource of each Home eNodeB configuration respective number, under the condition meeting the not multiplexing identical running time-frequency resource of adjacent base station, farthest meet business demand

After configuring running time-frequency resource for each Home eNodeB, travel through each Home eNodeB, often a selected current Home eNodeB, generates Home eNodeB group based on current Home eNodeB with all neighboring home base stations of current Home eNodeB;

If in the current available running time-frequency resource of system, when existing not to the running time-frequency resource of this Home eNodeB group configuration, the running time-frequency resource do not configured is recorded as the running time-frequency resource for subsequent use of current home base station in this Home eNodeB group.

Such as, if 3 Home eNodeB that base station A is adjacent with it are all unallocated to running time-frequency resource B in pre-provisioning procedure, then running time-frequency resource B is recorded as the running time-frequency resource for subsequent use of base station A, in follow-up Local resource cooperative arrangement process, for base station A, when pre-configured running time-frequency resource does not meet rate requirement, can use time-frequency resource allocating for subsequent use to this Home eNodeB A.

When the Home eNodeB start in centralized management equipment administration or Home eNodeB to move etc. cause home base station network change in topology time, then upgrade the neighbouring relations of Home eNodeB, and the running time-frequency resource of pre-configured each Home eNodeB again.

So far, the pre-configured running time-frequency resource process for Home eNodeB is introduced complete.

Consult shown in Fig. 3, in the embodiment of the present invention, between Home eNodeB, the flow process of cooperative arrangement running time-frequency resource is as follows:

Step 300: centralized management equipment receives the time-frequency resource allocating request that service Home eNodeB sends, this time-frequency resource allocating request serves when the Home eNodeB running time-frequency resource pre-configured in this locality does not meet user's access demand to send.

Particularly, in actual applications, when having new user or switching user initiates access request to some Home eNodeB (can be described as service Home eNodeB), first service Home eNodeB judges whether there is untapped running time-frequency resource in local pre-configured running time-frequency resource, if so, user's access is then allowed; If do not exist, or untapped running time-frequency resource is not enough to meet user's access demand, then serve Home eNodeB and send time-frequency resource allocating request to centralized management equipment, control resource collaboration between service Home eNodeB and other Home eNodeB by centralized management equipment and configure.

Step 310: the running time-frequency resource service condition that centralized management equipment reports according to each Home eNodeB, in the pre-configured running time-frequency resource determining the neighboring home base station serving Home eNodeB, do not exist when not using and the running time-frequency resource of user's access demand of service Home eNodeB can be met, calculate the value being assigned with each running time-frequency resource of use of neighboring home base station, wherein, the quality for characterizing a running time-frequency resource in neighboring home base station is worth.

Particularly, centralized management equipment is after the time-frequency resource allocating request receiving the transmission of service Home eNodeB, first judge whether the running time-frequency resource for subsequent use recording this service Home eNodeB, this running time-frequency resource for subsequent use namely in pre-provisioning procedure, not to this service Home eNodeB and neighboring home base station configuration running time-frequency resource, if, then distribute this running time-frequency resource for subsequent use to this service Home eNodeB, like this, both can meet the rate requirement of service Home eNodeB, interference can not have been caused to other Home eNodeB again.If after time-frequency resource allocating for subsequent use being given service Home eNodeB, user's access demand of service Home eNodeB can be met, then do not perform follow-up transference (i.e. cooperative arrangement process).

Otherwise centralized management equipment performs follow-up cooperative arrangement process.Specific as follows:

Centralized management equipment requires that each Home eNodeB reports running time-frequency resource service condition, and the channel quality parameter on each running time-frequency resource, such as, channel quality parameter can be, but not limited to comprise Signal to Interference plus Noise Ratio (SignaltoInterferenceplusNoiseRatio, SINR), centralized management equipment stores the running time-frequency resource service condition of each Home eNodeB collected and channel quality parameter.

The running time-frequency resource service condition that centralized management equipment reports according to each Home eNodeB, judges whether there is untapped pre-configured running time-frequency resource in each neighboring home base station of service Home eNodeB.

The pre-configured running time-frequency resource not using if exist in the neighboring home base station of service Home eNodeB and service Home eNodeB access user demand can be met, then this untapped time-frequency resource allocating is given service Home eNodeB (can be regarded as service Home eNodeB and use this untapped running time-frequency resource to corresponding adjacent base station), and send signaling to corresponding neighboring home base station, this signaling is used to indicate neighboring home base station by this untapped time-frequency resource labels for using, after the use of service femtocell user terminates, report this running time-frequency resource to finish using to centralized management equipment, centralized management equipment sends signaling to corresponding neighboring home base station again according to reported result, notify that the running time-frequency resource used is given back in corresponding neighboring home base station by it, and temporary for this running time-frequency resource disabled mark is cancelled.

If there is not untapped running time-frequency resource in the neighboring home base station of service Home eNodeB, then centralized management equipment is initiated one to each Home eNodeB and is taken turns resource transfer recursive procedure; If there is the running time-frequency resource not using but service Home eNodeB access user demand can not be met in the neighboring home base station of service Home eNodeB, then same give service Home eNodeB by this time-frequency resource allocating after, perform follow-up transfer recursive procedure.

Transfer recursive procedure is specially:

First, the value of each running time-frequency resource in the neighboring home base station of centralized management equipment calculation services Home eNodeB.Computational methods are:

S1: respectively for each neighboring home base station of service Home eNodeB, the channel quality parameter of each running time-frequency resource being assigned with use is sorted, and determines the sequence number of each running time-frequency resource in each neighboring home base station according to ranking results.Wherein, each running time-frequency resource that the neighboring home base station calculated is assigned with use is the running time-frequency resource that neighboring home base station is using, these running time-frequency resources may be all the running time-frequency resources configured in the pre-provisioning procedure of neighboring home base station, also may have part be in the whole network coordination process before neighboring home base station use but the running time-frequency resource also do not given back.

Such as, channel quality parameter is SINR, then sorted from small to large according to SINR by each running time-frequency resource be assigned in each neighboring home base station, and determines the sequence number of each running time-frequency resource in the neighboring home base station at place according to ranking results, sequence number, from 1, adds 1 successively.

According to ranking results, be non-assignable by time-frequency resource labels maximum for SINR, can not transfer be performed with the top-quality running time-frequency resource of indicating channel in follow-up transference.The service quality of the neighboring home base station after transferring the possession of can be ensured so as far as possible.

Wherein, same running time-frequency resource only may be assigned to a neighboring home base station in pre-provisioning procedure, also may be assigned at least two neighboring home base stations, according to different pre-configured results, and the service condition of running time-frequency resource in current network, different value calculation modes is set.

S2: if any one running time-frequency resource is assigned with use in a neighboring home base station, then according to the running time-frequency resource sum that the neighboring home base station assigns at this any one running time-frequency resource place arrives, with the sequence number of this any one running time-frequency resource, determine the value of this any one running time-frequency resource.

Such as, running time-frequency resource C is only assigned in the D of neighboring home base station, is divided into and has been fitted on 3 running time-frequency resources in the D of neighboring home base station, according to the ranking results of these 3 running time-frequency resource SINR, the sequence number of running time-frequency resource C is 1, and namely the SINR of running time-frequency resource C is minimum, then the value of running time-frequency resource C is 1/3.

Or,

If this any one running time-frequency resource is assigned with use at least two neighboring home base stations, then according to the running time-frequency resource sum that each the neighboring home base station assigns at least two neighboring home base stations at this any one running time-frequency resource place arrives, with the sequence number of this any one running time-frequency resource of correspondence, determine the value of this any one running time-frequency resource.

Such as, running time-frequency resource E is at neighboring home base station F, use is assigned with in H, be divided in the F of neighboring home base station and be fitted on 3 running time-frequency resources, according to the ranking results of these 3 running time-frequency resource SINR, the sequence number of running time-frequency resource E is 1, be divided in the H of neighboring home base station and be fitted on 2 running time-frequency resources, according to the ranking results of these 2 running time-frequency resource SINR, the sequence number of running time-frequency resource E is 2, then calculate the son of running time-frequency resource E in F and H of neighboring home base station to be respectively worth, and two that obtain son value are carried out quadrature computing, obtain the value of running time-frequency resource E, then the value of running time-frequency resource E is 1/3 × 2/2=1/3.

Wherein, the quality for characterizing a running time-frequency resource in neighboring home base station is worth.The interference of the computational methods comprehensive examination and evaluation running time-frequency resource be worth and noise and in the neighboring home base station situation of access times.

Step 320: centralized management equipment is worth based on each running time-frequency resource being assigned with use of neighboring home base station, successively by running time-frequency resource to service Home eNodeB transfer, until meet user's access demand of service Home eNodeB.

Particularly, the value of each running time-frequency resource in the neighboring home base station of service Home eNodeB sorts by centralized management equipment, according to order from small to large successively by running time-frequency resource to service Home eNodeB transfer, namely first minimum running time-frequency resource will be worth to service Home eNodeB transfer, if user's access demand of service Home eNodeB still can not be met after transferring the possession of, then continue to be worth secondary little running time-frequency resource to service Home eNodeB transfer, until the running time-frequency resource transferred the possession of can meet user's access demand of service Home eNodeB, then mark service Home eNodeB exits transference.And, be non-assignable by all time-frequency resource labels of service Home eNodeB, do not participate in follow-up compensation process to indicate service Home eNodeB.

Step 330: centralized management equipment compensates, until all Home eNodeB meet the data-rate requirements of corresponding user for the rate loss of the neighboring home base station after transfer.

Particularly, after service Home eNodeB exits, centralized management equipment calculates the rate loss of the neighboring home base station after transferring the possession of.If running time-frequency resource has been transferred the possession of for this service Home eNodeB at least two neighboring home base stations, then sort according to rate loss order from big to small, the basis of rate loss is that the running time-frequency resource number of transfer is divided by the sum being assigned with the running time-frequency resource of use before transfer.Successively compensate the rate loss of the neighboring home base station after transfer successively according to sequence, for the neighboring home base station after some transfers, the process of compensation specifically comprises:

For the neighboring home base station after transferring the possession of distributes the first running time-frequency resource, the second running time-frequency resource, the 3rd running time-frequency resource and the 4th running time-frequency resource successively, until meet the data-rate requirements of the user of the neighboring home base station after transferring the possession of;

Wherein, the untapped pre-configured running time-frequency resource existed in neighboring home base station after first running time-frequency resource refers to transfer, the running time-frequency resource for subsequent use existed in neighboring home base station after second running time-frequency resource refers to described transfer, the neighboring home base station of the neighboring home base station after this running time-frequency resource for subsequent use is not transferred uses, 3rd running time-frequency resource refers to untapped pre-configured running time-frequency resource in the neighboring home base station of the neighboring home base station after described transfer, 4th running time-frequency resource refers in the neighboring home base station of the neighboring home base station after described transfer, be worth based on each running time-frequency resource, successively to the running time-frequency resource that the neighboring home base station after transfer is transferred the possession of.

In said process, if there is not a certain class running time-frequency resource, then remove such non-existent running time-frequency resource according to original order, perform assigning process.Such as, if there is not the first running time-frequency resource, then for the neighboring home base station after transfer distributes the second running time-frequency resource, the 3rd running time-frequency resource and the 4th running time-frequency resource successively.

If neighboring home base station assigns the 4th running time-frequency resource after transfer, rate loss then for the Home eNodeB of transfer the 4th running time-frequency resource compensates, until no longer cause the rate loss of other neighboring home base stations in compensation process, all Home eNodeB can be made to meet the data-rate requirements of corresponding user.

Wherein, compensate in process in the rate loss for the neighboring home base station after transfer, if one transfer the possession of after neighboring home base station assigns the 4th running time-frequency resource, then after dispensing, all time-frequency resource labels of the neighboring home base station after this being transferred the possession of are non-assignable, and the neighboring home base station after transferring the possession of to indicate this does not participate in follow-up compensation process.

The allocation result finally obtained is sent to the Home eNodeB relating to running time-frequency resource variation by centralized management equipment.

So far, between Home eNodeB, the method for cooperative arrangement running time-frequency resource is introduced complete.

Below in conjunction with concrete application scenarios, the embodiment of the present invention is described in further detail.

Consulting shown in Fig. 4, is the operative scenario of the enterprise-level TD-LTE Home eNodeB centralized configuration resource based on dense deployment.The enterprise-level Home eNodeB owner arranges Home eNodeB centralized management equipment (abbreviation centralized management equipment) in a network, centralized management equipment is connected with 7 Home eNodeB respectively through local return network, and 7 Home eNodeB are deployed in adjacent offices in same office building.

Consult shown in Fig. 5, suppose that 7 Home eNodeB use SC1, SC2 respectively ... SC7 represents, the total number of the current available Physical Resource Block PRB (PhysicsResourceBlock) of system is that 10,10 PRB use PRB1 respectively, PRB2 ..., PRB10 represents.Illustrate the method for centralized configuration resource in application process below.

Such as, in application process, SC1, SC2 ..., SC6 first starts shooting, and SC7 is in off-mode.Centralized management equipment is the pre-configured PRB of SC1-SC6.Pre-provisioning procedure is as follows:

(1) centralized management equipment determines the neighbouring relations of each Home eNodeB of SC1-SC6.

Particularly, it is adjacent area (or being called adjacent base station) by covering area overlapping or adjacent cell configuration in the Home eNodeB in administration.Such as, the adjacent area of to be the adjacent area of SC3, SC2 be the adjacent area of SC1 SC3, SC3 has 3, is respectively SC1, SC2 and SC4.

(2) centralized management equipment is according to the neighbouring relations of each Home eNodeB, calculates the PRB number that each Home eNodeB is pre-configured.

Computing formula is:

formula [1]

Wherein, PRB _configrepresent the number of the pre-configured PRB of certain Home eNodeB, PRB _allthe current assignable PRB sum of expression system, Neighbor_cell represents the number of the adjacent base station of base station, represent and round downwards.

According to formula [1], calculate respectively, such as, for SC1, by PRB for the number of the pre-configured PRB of SC1-SC6 before the non-access network of SC7 _all=10, Neighbor_cell=1, substitutes into formula [1] and calculates, obtain PRB _configvalue be 5; For SC2, by PRB _all=10, Neighbor_cell=1, substitutes into formula [1] and calculates, obtain PRB _configvalue be 5; For SC3, by PRB _all=10, Neighbor_cell=3, substitutes into formula [1] and calculates, obtain PRB _configvalue be 2; For SC4, by PRB _all=10, Neighbor_cell=1, substitutes into formula [1] and calculates, obtain PRB _configvalue be 5; For SC5, by PRB _all=10, Neighbor_cell=1, substitutes into formula [1] and calculates, obtain PRB _configvalue be 5; For SC6, by PRB _all=10, Neighbor_cell=1, substitutes into formula [1] and calculates, obtain PRB _configvalue be 5.

SC7 does not access each Home eNodeB PRB of front network _configvalue as follows:

SC1：5；SC2：5；SC3：2；SC4：5；SC5：5；SC6：5。

(3) centralized manager is the PRB of the pre-configured respective number of each Home eNodeB, and pre-configured result need meet the not multiplexing identical PRB in adjacent area.

More preferably, greedy algorithm can be adopted to be the pre-configured PRB of each Home eNodeB, each Home eNodeB be obtained in the whole network and is used minimum PRB.Especially, if multiple PRB the whole network access times are identical, the PRB that priority allocation numbering is less, wherein, e.g., PRB8 is numbered 8.

Layoutprocedure adopts tree-like ergodic algorithm, first with the Home eNodeB of the whole network smallest sequence number for starting point is distributed, then in neighboring home base station by sequence number from small to large order be followed successively by adjacent base station and carry out pre-configured based on remaining PRB.After distributing adjacent Home eNodeB, determining whether for the pre-configured PRB in all base stations of the whole network, if not, be then new starting point with the adjacent base station that sequence number in starting point Home eNodeB is minimum is the pre-configured PRB of its adjacent base station.If there is no not pre-configured adjacent base station as in the Home eNodeB of ground zero, what then return upper level plays point base stations, be that new starting point repeats above step with time little base station of sequence number in its adjacent base station, and search out not pre-configured adjacent base station and distribute after, be new starting point with adjacent base station; If without unallocated adjacent base station, repeat said process, until travel through all adjacent base stations.If do not find unallocated base station after traversal adjacent base station, namely there is not the not pre-configured PRB in adjacent base station, with the not pre-configured Home eNodeB of smallest sequence number for the pre-configured PRB of ground zero.Repeat said process, until all pre-configured PRB of all Home eNodeB.

Such as, obtaining SC1-SC6 according to step (2) needs the PRB number distributed to be respectively 5,5,2,5,5,5.

According to tree-like ergodic algorithm, be first pre-configured 5 PRB of SC1 of the whole network smallest sequence number, configure successively according to sequence number order from small to large in whole PRB, then for SC1 by 5 PRB that sequence number is pre-configured be: PRB1 ..., PRB5;

Then be SC3 that SC1 is adjacent pre-configured 2 PRB:PRB6, PRB7 in order in remaining 5 PRB (i.e. PRB6 ~ PRB10);

After SC1 adjacent base station distributes pre-configured PRB, then with the minimum Home eNodeB (SC3) of sequence number in SC1 adjacent base station for new starting point is the pre-configured PRB of its adjacent base station, namely with the starting point that SC3 is new, be followed successively by its adjacent area SC2, SC4 pre-configured PRB, SC2 and distribute in remaining 8 PRB (i.e. PRB1 ~ PRB5, PRB8 ~ PRB10) pre-configured 5 PRB:PRB8 ~ PRB10, PRB1, PRB2 in order based on SC3;

Then be the adjacent area distribution PRB of SC2, because the adjacent area SC3 of SC2 distributes PRB, without unallocated adjacent base station, then turn back to SC4 pre-configured, SC4 to distribute in remaining 8 PRB (i.e. PRB1 ~ PRB5, PRB8 ~ PRB10) pre-configured 5 PRB:PRB3 ~ PRB5, PRB8, PRB9 in order based on SC3;

Being that starting point finds no unallocated adjacent base station with SC4, is finally ground zero pre-configured 5 PRB:PRB10, PRB1 with SC5 ..., PRB4;

Then be pre-configured 5 the PRB:PRB5 ~ PRB9 of SC5 adjacent base station SC6, complete the PRB of the whole network Home eNodeB pre-configured.

When SC7 starts shooting, network topology change, be the pre-configured PRB of all base station assigns again, concrete assigning process performs according to the method described above, and allocation result as shown in Figure 5.The pre-configured PRB of final SC1 is: PRB1 ~ PRB5; The pre-configured PRB of SC3 is: PRB6 and PRB7; The pre-configured PRB of SC2 is: PRB8 ~ PRB10; The pre-configured PRB of SC4 is: PRB1 ~ PRB3; The pre-configured PRB of SC7 is: PRB4 and PRB5; The pre-configured PRB of SC5 is: PRB6 ~ PRB8; The pre-configured PRB of SC6 is: PRB9, PRB10, PRB1 ~ PRB3.

Preferably, after pre-configured completing, centralized management equipment travels through each Home eNodeB, an often selected current Home eNodeB, by this Home eNodeB and adjacent Home eNodeB composition one family group of base stations thereof, judge in 10 PRB, whether to there is this Home eNodeB group untapped PRB in pre-provisioning procedure, if having, then corresponding PRB is recorded as the PRB for subsequent use of each Home eNodeB of this Home eNodeB group.

So far, the pre-configured PRB of SC1 ~ SC7 is complete.

Can there is PRB distribution conflict in network actual motion, consult shown in Fig. 6, the process of embodiment of the present invention local coordinated resource allocation is exemplified below.

Suppose that certain moment network PRB service condition is as shown in a in Fig. 6, such as, SC1 employs pre-configured resource PRB1, PRB2, PRB3, does not use pre-configured resource to be PRB4 and PRB5.

1) when there being user to initiate access request, service Home eNodeB judges whether this locality exists untapped pre-configured PRB, if exist, then uses pre-configured PRB, otherwise sends resource allocation request to centralized management equipment.

Such as, the new user in SC7 coverage or incision user initiate access request to SC7, and SC7 judges that local pre-configured PRB4 and PRB5 is used by other users, then send resource allocation request to centralized management equipment.

2) after centralized management equipment receives the resource allocation request of service Home eNodeB transmission, for service Home eNodeB distributes other appropriate resources.

Particularly, centralized management equipment sends signaling to each Home eNodeB of the whole network, requires the situation of situation and the load demand reporting PRB to use, and reports the SINR value of each PRB.If the adjacent base station of service Home eNodeB exists reusablely do not use pre-configured PRB, and the user rate demand of service Home eNodeB can be met, then reusablely do not use pre-configured PRB for this service Home eNodeB distributes this, and send signaling to this neighboring home base station, this PRB is labeled as and wouldn't uses, and service Home eNodeB reports this PRB to use end to centralized management equipment after user's use terminates, centralized management equipment sends signaling according to reported result to this neighboring home base station, notifies that the PRB used is labeled as available by it.

If there is not untapped pre-configured PRB in the neighboring home base station of service Home eNodeB, or, there is untapped pre-configured PRB but after the distribution of service Home eNodeB, still cannot meet the user's request of service Home eNodeB, then perform step 3).

Such as, after centralized management equipment obtains the whole network PRB service condition, judge whether the adjacent base station of SC7 exists and reusablely do not use PRB, the adjacent base station of SC7 has SC2, SC3, SC4 and SC5, from the PRB service condition of the whole network, the pre-allocated recourses PRB3 of SC4 is not used, and for the new user of SC7 distributes PRB3, and notifies that PRB3 is labeled as by SC4 and wouldn't use.Although the resource PRB8 being assigned with use of SC5 is not used by SC5, but PRB8 is used by SC2, therefore for avoiding the interference between adjacent area, do not consider that PRB8 being distributed to SC7 uses, suppose that the new user of SC7 still cannot satisfy the demands after obtaining PRB3, around without multiplexing PRB, perform step 3).

3) centralized management equipment is initiated one to the whole network Home eNodeB and is taken turns resource transfer recursive procedure:

1. the PRB of each neighboring home base station of service Home eNodeB is sorted from small to large by Signal to Interference plus Noise Ratio (SINR), use φ _i(φ _i=1,2...m) represent the ranking results of PRBi.

Such as, the base station SC2 that SC7 is adjacent, the PRB used in SC3, SC4, SC5 sorts by SINR, and the result of sequence is as shown in the c in Fig. 6, and in each community, the PRB m bit representation that sorts is φ _i=m.

Such as, in SC2, the ranking results of the ranking results of PRB9 to be the ranking results of 1, PRB10 be 2, PRB8 is 3.Namely, the SINR value of PRB9 is minimum, and the SINR value of PRB8 is maximum.

2. the value of PRB that uses of the adjacent base station of calculation services Home eNodeB, by being worth from low to high for service Home eNodeB distributes PRB, being assigned rear centralized management equipment mark service Home eNodeB and exiting follow-up transference.

Wherein, the cost function of running time-frequency resource is:

P_{i H} = Π_{j = 1}^{j = k} \frac{φ_{P R B i j}}{ϵ_{j}}

Formula [2]

Suppose that the Home eNodeB number that centralized management equipment is administered is n, P _iHrepresent Home eNodeB H (H=1,2 ... the value of the PRBi that neighboring home base station n) uses, k represents the neighboring home base station number that there is interference relationships with Home eNodeB H, φ _pRBijrepresent the sequence number of PRBi at Home eNodeB j, ε _jrepresent the total number of PRB of Home eNodeB j.Especially, if multiple PRB is worth identical, the PRB using more number of times is preferentially used in neighbor cell.

Be can be calculated in the neighboring home base station of SC7 by formula [2], the value of each PRB is as follows:

PRB1：1/2；PRB2：1；PRB6：1/4；PRB7：1；PRB8：1；PRB9：1/3；PRB10：2/3。

PRB sorts from high to low by value: 2,7,8,10,1,9,6.

According to result of calculation, the value of PRB6 is minimum, therefore first for SC7 distributes PRB6.If do not meet SC7 user rate demand after distributing, then continue as SC7 and distribute PRB9, until meet user rate demand in SC7, mark SC7 exits transference.As shown in fig 6d, for SC7 be assigned with PRB6 after meet its rate requirement, then mark SC7 exit transference.

3. centralized management equipment calculates the rate loss transferred the possession of and bring.

Centralized management equipment sorts from big to small according to rate loss, and sort by is that each Home eNodeB transfers the possession of PRB number divided by the PRB sum being assigned with use before each Home eNodeB transfer.If it is identical to there is rate loss, preferentially less to Home eNodeB sequence number Home eNodeB compensates, if nothing, then successively compensates according to sequence.

Compensation process: whether the preferential Home eNodeB judging to lose PRB exists does not use and reusable pre-configured PRB, if having, uses this pre-configured PRB; If nothing, then judge whether that the neighboring home base station of the Home eNodeB that there is loss PRB does not use, and do not belong to the reusable PRB of the adjacent base station pre-allocated recourses of the Home eNodeB of loss PRB, if having, this PRB is distributed to the Home eNodeB of loss PRB; If nothing, then judge whether that the adjacent base station of the Home eNodeB that there is loss PRB does not use, and meet the pre-configured PRB of the Home eNodeB rate requirement of loss PRB, if having, use this PRB, and indicate corresponding this PRB of neighboring home basestation marker for using; If nothing, then require that the neighboring home base station of the Home eNodeB of loss PRB is transferred the possession of.

Such as, SC3 and SC5 is after transferring the possession of out PRB6, and rate loss sequence is: SC3 (rate loss is 1/2), SC5 (rate loss is 1/2), the rate loss of two base stations is identical, then recover damage the preferential SC3 little from base station sequence number.

Owing to there is no untapped PRB in Home eNodeB around SC3, require that adjacent base station continues to transfer the possession of.Wherein, SC7 obtains PRB from transfer, no longer participates in.Repeat PRB value calculation process (PRB wherein distributed for SC7 does not enter computational process), the value obtaining PRB is respectively: PRB1:1/6, PRB2:2/3, PRB8:1, PRB9:1/3, PRB10:2/3, by being worth sequence from small to large for PRB1, PRB9, PRB2, PRB10, PRB8, wherein PRB2 and PRB10 is worth is all 2/3, and clooating sequence carries out according to the rule be arranged in front that PRB sequence number is little.

Consult shown in the e in Fig. 6, SC3 obtains the PRB1 in SC1 and SC4, and SC3 exits this and transfers the possession of, and no longer participates in follow-up flow process, SC1 and SC4 rate loss.

Next first compensate the PRB loss because SC3 transference causes, the rate loss of SC1 and SC4 is respectively 1/3 and 1/2.Then according to the descending order of rate loss first for SC4 compensates, because its pre-configured resource PRB1,4 are used by its neighboring home base station, SC4 and neighboring home base station thereof all do not configure PRB8 ~ PRB10 in pre-provisioning procedure, and PRB8 ~ PRB10 is not yet assigned to the neighboring home base station of SC4 at present, then according to the order that sequence number is ascending be SC4 distribute PRB8.

Next for SC1 distribute that it configures in pre-provisioning procedure and not by around the PRB5 of Home eNodeB use.

Finally, for SC5 distribute that it configures in pre-provisioning procedure and not by around Home eNodeB use PRB8.

Because the process for SC1 and SC5 rate compensation does not all cause the rate loss of other neighboring home base stations again.Therefore epicycle resource transfer recursive procedure is complete.

4) allocation result is sent to the Home eNodeB relating to resource change by centralized management equipment.
