Description

Carry out the method and the base station of channel allocation
Technical field
The present invention relates to wireless communication technology field, be specifically related to a kind of method and base station of carrying out channel allocation.
Background technology
For the purpose of subsequent descriptions is convenient, at first provide to give a definition:
System: base station (BS) and terminal (SS) construction system that is associated with it.
Neighborhood: at least one BS in two systems is higher than the thresholding of setting to the interference value of at least one SS of another system, perhaps, when in two systems, when at least one SS of at least one system is higher than the thresholding of setting to the interference value of the BS of another system, claim this two system to constitute neighborhood.
Neighbours: have another system of neighborhood to be called the neighbours of this system with a system.
Neighbours BS: a system and another system are neighbours, then lay respectively at two BS the other side's the neighbours BS each other in this two system.
Disturb the adjacent area: the interference adjacent area of a system is defined as all and this system is produced all other systems that disturb or be subjected to this system interference.
Disturb sacrificial system: BS in a system or SS are disturbed by the neighbours of this system, and interference value is higher than the thresholding of setting, and then this system is called the interference sacrificial system.Disturbing sacrificial system may be its neighbours' interference source system simultaneously, perhaps only is the interference sacrificial system of neighbours system.
The interference source system: when the BS in the system or SS to the neighbours' of this system interference value when setting thresholding, claim that then this system is the interference source system.The interference source system may be its neighbours' interference sacrificial system simultaneously, perhaps only is neighbours' interference source system.
Wireless frequency spectrum is divided into authorizes frequency range and unauthorized frequency range, authorizing frequency range is the wireless transmission band of opening up for a certain radio communication service specially, other radio communication service can not be in this band transmissions, authorize the common fixed allocation of frequency range to give a certain operator, operator can be optimized the frequency range that each node adopted in the system, to reduce the phase mutual interference between the node; Unauthorized frequency range then can fixed allocation not given a certain operator, all radio communication services that meet certain requirements all can use this frequency range, because the frequency that each radio communication service node adopts is unfixing, there is not operator that unauthorized frequency range is optimized yet, therefore, between each radio communication service that transmits on the unauthorized frequency range, may interfere with each other.
For the coexistence in the BWA that realizes unauthorized frequency range, perhaps in order better to realize the intrasystem coexistence with cognitive radio function of use authority frequency range, and the coexistence of unauthorized frequency range and mandate frequency range system, international IEEE (IEEE) 802 Local Area Network/metropolitan area network (MAN) standard committee sets up a series of working group and formulates relevant cognition wireless electric standard, comprise 802.11y, 802.16h, 802.22 etc.Wherein, IEEE 802.16h has formulated the method for evading interference by time-sharing channel, detailed process is as follows: with each up medium access control (MAC) frame and descending mac frame of a system, neighbours according to this system count N, be divided into N+1 subframe respectively, wherein, a subframe is used to transmit glitch-free business, all the other N subframe is respectively applied for each neighbours' timesharing transmission and disturbs professional.
Fig. 1 is system BS0, the BS1 interference relationships schematic diagram of two phase mutual interference, as shown in Figure 1, if BS0 and BS1 are neighbours, and BS0 and SS0, SS3 belong to same system, BS1 and SS1, SS2 belong to same system, then because the transmission channel between transmission channel, BS1 and the SS2 between BS0 and the SS3 is same channel, disturb so BS0 can produce SS2, BS1 can produce SS3 and disturb.
Fig. 2 is for being example with BS0 among Fig. 1 and BS1, the schematic diagram that the interference bypassing method of time-sharing channel is described, as shown in Figure 2, a descending mac frame is divided into three subframes, first subframe is used to transmit noiseless business and sends professional as: BS0 to SS0 by this subframe, BS1 can send professional by this subframe to SS1 simultaneously, second subframe be used for BS0 transmission interfered with service as: BS0 sends professional by this subframe to SS3, BS1 does not use this subframe simultaneously, the 3rd subframe be used for BS1 transmission interfered with service as: BS1 sends professional to SS2 by this subframe, BS1 does not use this subframe simultaneously.The use of up mac frame is identical with descending mac frame.
The shortcoming of this interference bypassing method is: only when BS initially inserts, this BS is carried out neighbours' detection, and carry out the distribution of channel according to the neighbours that determine, after a BS is defined as the neighbours of another BS, this neighborhood is no longer changed, that is: have only the access of BS, just can cause the neighborhood of BS to change.But, in actual applications, normal operating phase after BS inserts, because the SS that this BS is associated closes, also can cause the neighborhood of this BS to change, as shown in Figure 1, if SS2 and SS3 close, then the neighborhood of BS0 and BS1 is removed, and there is no need shared channel to BS1 and BS2 this moment again and carries out timesharing and divide.Prior art reckons without this aspect, obviously, can reduce utilization rate of channel resources greatly like this.

Here whether, exist the indication of descending interference sacrifice, descending interference to sacrifice being subjected to the number of the SS of native system interference in neighbours' sum and the descending interference sacrifice neighbours is optional parameters, and the initial value of this three parameter can be made as 0.
Among the present invention, descending interference is sacrificed the SS that disturbed by native system in the neighbours and is abbreviated descending interference sacrifice SS as, the number that the SS that is subjected to the native system interference in the neighbours is sacrificed in then descending interference abbreviates descending interference sacrifice SS number as, and the SS sign that disturbed by native system in the descending interference sacrifice neighbours abbreviates descending interference sacrifice SS as and identifies.
When this BS inserts, if the associated SS of neighbours BS receives the downstream signal that this BS sends, then neighbours BS can send the descending interference sacrifice of the renewal request message that carries the SS sign that neighbours BS identifies and neighbours BS is associated to this BS, after this BS receives this message, add neighbours BS sign to descending interference and sacrifice in the tabulation, simultaneously that neighbours BS is associated SS sign is added descending interference to and is sacrificed in the SS identification list.
Step 402:BS is in running, and the associated SS of BS detects the downstream signal that neighbours BS sends, and sends to this BS and upgrades the down interference source request message, and this message is carried the IP address, this SS sign of neighbours BS sign, neighbours BS etc.
After step 403:BS receives the renewal down interference source request message that self associated SS sends, judge in self the down interference source tabulation whether comprise the neighbours BS sign that this message is carried, if, execution in step 404; Otherwise, execution in step 407.
In this step, BS can whenever receive and once upgrade the down interference source request message just whether comprise the neighbours BS sign that this message is carried in the down interference source tabulation of judging once self, and carry out subsequent step according to judged result; Also can, preestablish a timing length, after each timing begins, the number of times that writes down that each SS sends at the renewal down interference source request message of each neighbours BS sign, if certain specific SS of in this timing length, receiving send at the number of times of the renewal down interference source request message of certain particular neighbor BS sign greater than preset times, then judge in self the down interference source tabulation whether comprise this specific neighbours BS sign, and carry out subsequent step according to judged result.
Step 404:BS judges that whether comprising the SS that this message carries in the corresponding descending SS of the being disturbed identification list of this neighbours BS sign in the tabulation of self down interference source identifies, if, do not deal with, go to step 411; Otherwise, execution in step 405.
The SS sign that step 405:BS carries this message is added in the corresponding descending SS of the being disturbed identification list of this neighbours BS sign in self down interference source tabulation, simultaneously, the corresponding descending SS of the being disturbed number of this neighbours BS sign is added 1.
Step 406:BS on self the descending interference timesharing channel, to this SS transport service, goes to step 411 in DSCH Downlink Shared Channel.
In the DSCH Downlink Shared Channel with BS, be used for being called descending noiseless timesharing channel, will be used for each BS is called descending interference timesharing channel from each BS to the timesharing channel of the descending SS of the being disturbed transport service of self to the timesharing channel of the SS transport service that is not subjected to any interference.
The number of the neighbours BS sign that step 407:BS carries this message, the IP address of neighbours BS, SS sign, SS: 1 corresponding relation adds in the down interference source tabulation of self.
If comprise whether there is the down interference source indication in the down interference source tabulation, and this indicated value is 0 before carrying out this step, then in this step, this indicated value is made as 1; If comprise down interference source neighbours sum in the down interference source tabulation, then in this step, this total value added 1.
Step 408:BS judges the descending interference of self sacrifices whether comprise this neighbours BS sign in the tabulation, if, execution in step 409; Otherwise, execution in step 410.
Step 409:BS to this SS transport service, goes to step 411 on self descending interference timesharing channel of DSCH Downlink Shared Channel.
Step 410:BS determines self to have increased new descending neighbours, carries out channel assignment negotiation with current self descending neighbours, and carries out channel allocation and professional transmission according to the channel allocation strategy after consulting.
Descending neighbours comprise: neighbours are sacrificed in down interference source neighbours and descending interference, if system's system is to sacrifice neighbours for the down interference source neighbours and the descending interference of native system, then this system is calculated as 1 neighbour at the descending neighbours' sum of calculating.
Timesharing distribution principle to shared channel among the present invention is same as the prior art.
That step 411:BS detects is that a descending SS of being disturbed not receiving in scheduled duration in the tabulation of self down interference source sends, carry the renewal down interference source request message of down interference source neighbours BS sign corresponding with this SS in the down interference source tabulation, then determine the interference relationships releasing of this SS, delete in the descending SS of the being disturbed identification list that this down interference source neighbours BS sign of this SS sign from the down interference source tabulation is corresponding, simultaneously the corresponding descending SS of the being disturbed number of this down interference source neighbours BS sign is subtracted 1.
BS also can set a timing length, after each timing begins, each descending SS of being disturbed in self down interference source tabulation that detection is received sends, carry the number of times of the renewal down interference source request message of down interference source neighbours BS sign corresponding in the down interference source tabulation with this SS, if in this timing length, this number of times is less than preset times, delete in then that this down interference source neighbours BS sign of this SS sign from the down interference source tabulation is the corresponding descending SS of the being disturbed identification list, simultaneously the corresponding descending SS of the being disturbed number of this down interference source neighbours BS sign is subtracted 1.
Step 412:BS judges whether the corresponding descending SS of the being disturbed number of this neighbours BS sign is 0, if, execution in step 413; Otherwise, not dealing with, this flow process finishes.
This step also can be: BS judges whether the corresponding descending SS of the being disturbed identification list of this neighbours BS sign is empty, if, execution in step 413; Otherwise, not dealing with, this flow process finishes.
The relevant information of this down interference source neighbours in the tabulation of step 413:BS deletion down interference source comprises: this down interference source neighbours BS sign, the IP address of this down interference source neighbours BS, the descending SS of the being disturbed number of this down interference source neighbours BS: 0.
If comprise whether have down interference source indication and down interference source neighbours sum in the down interference source tabulation, and after carrying out this step, do not comprise any neighbours BS sign in the down interference source tabulation, then described indicated value is made as 0, described total value is made as 0; If after carrying out this step, also comprise neighbours BS sign in the down interference source tabulation, then described total value is subtracted 1.
Step 414:BS judges down interference source tabulation of self and descending interference sacrifice to tabulate whether do not comprise any neighbours BS sign, if, execution in step 415; Otherwise, execution in step 416.
Step 415:BS distributes down channel again, and this flow process finishes.
Step 416:BS judges the descending interference of self sacrifices whether comprise this neighbours BS sign in the tabulation, if, not dealing with, this flow process finishes; Otherwise, execution in step 417.
The descending neighbours that step 417:BS defines self system discharge, and according to current descending neighbours' sum, carry out DSCH Downlink Shared Channel again and distribute, and carry out business according to the channel after distributing and transmit.
It is pointed out that step 402～410 and step 411～417 there is no the branch of priority.
Fig. 5 is descending interference that the embodiment of the invention two the provides increase of sacrificing neighbours, discharge and cause the flow chart that down channel distributes again, and as shown in Figure 5, its concrete steps are as follows:
Step 501:BS initial access network detects the down interference source neighbours and the descending interference of self system and sacrifices neighbours, and sets up down interference source tabulation and descending interference and sacrifice and tabulate.
Step 502:BS is in running, and the associated SS of neighbours BS detects the downstream signal that this BS sends, and sends to neighbours BS and finds new interference source message, and this message is carried the sign of this BS, the IP address of this BS, the sign of this SS etc.
Step 503: after neighbours BS receives the new down interference source message of discovery that the SS of self sends, send to this BS and to upgrade descending interference and sacrifice request message, this message is carried neighbours BS sign, the IP address of neighbours BS, the associated SS of neighbours BS and is identified.
In this step, after neighbours BS receives the new down interference source message of discovery that the SS of self sends, also can not send to this BS at once and upgrade descending interference sacrifice request message, and just this BS sign is preserved as the down interference source sign of self, when the descending interference sacrifice of the renewal of predefined this BS arrives constantly, send to this BS and upgrade descending interference sacrifice request message, record has sent to this BS and has upgraded the indication information that request message is sacrificed in descending interference simultaneously.
After step 504:BS receives that upgrading descending interference sacrifices request message, judge the descending interference of self sacrifices whether comprise the neighbours BS sign that this message is carried in the tabulation, if, execution in step 505; Otherwise, execution in step 507.
In this step, BS can receive whenever that once upgrading descending interference sacrifices request message, just judges once the descending interference of self sacrifices whether comprise the neighbours BS sign that this message is carried in the tabulation, and carries out subsequent step according to judged result; Also can, preestablish a timing length, after each timing begins, that writes down that each neighbours BS sends sacrifices the number of times of request message at the descending interference of renewal of each SS sign, if the descending interference of renewal at certain specific SS sign that certain the particular neighbor BS that receives in this timing length sends is sacrificed the number of times of request message greater than preset times, judge then the descending interference of body sacrifices whether comprise this specific neighbours BS sign in the tabulation, and carry out subsequent step according to judged result.
Step 505:BS judges the descending interference of self sacrifices in the descending interference sacrifice SS identification list of this neighbours BS sign correspondence in the tabulation whether comprise the SS sign that this message is carried, if, do not deal with, go to step 510; Otherwise, execution in step 506.
The SS sign that step 506:BS carries this message is added the corresponding descending interference of this neighbours BS sign that self descending interference sacrifices in the tabulation to and is sacrificed in the SS identification list, simultaneously, the corresponding descending interference of this neighbours BS sign in the tabulation is sacrificed in self descending interference sacrifice the SS number and add 1, go to step 510.
The SS number is sacrificed in the neighbours BS sign that step 507:BS carries this message, the IP address of neighbours BS, SS sign and descending interference: 1 corresponding relation adds the descending interference of self to and sacrifices in the tabulation.
Whether exist descending interference to sacrifice indication if descending interference sacrifices to comprise in the tabulation, and this indicated value is 0 before carrying out this step, then in this step, this indicated value is made as 1; Comprise descending interference sacrifice neighbours sum in the tabulation if descending interference is sacrificed, then in this step, this total value is added 1.
Step 508:BS judges whether the down interference source of self comprises this neighbours BS sign in tabulating, if, do not deal with, go to step 510; Otherwise, execution in step 509.
Step 509:BS determines self to have increased new descending neighbours, carries out the down channel assignment negotiation with current self descending neighbours, and carries out channel allocation and professional transmission according to the channel allocation strategy after consulting.
Step 510:BS detect in scheduled duration, do not receive self descending interference sacrifice a descending interference in the tabulation sacrifice that neighbours BS sends, carry and should descending interference sacrifice the corresponding descending interference of neighbours BS and sacrifice the descending interference sacrifice of the renewal request message that SS identifies, determine the interference relationships releasing of this descending interference sacrifice SS, then this SS sign is sacrificed the corresponding descending interference of this neighbours BS sign the tabulation from descending interference and sacrifice in the SS identification list and delete, the number that SS is sacrificed in simultaneously that this neighbours BS sign is corresponding descending interference subtracts 1.
BS also can set a timing length, after each timing begins, self descending interference that detection is received is sacrificed each descending interference in the tabulation and is sacrificed that neighbours BS sends, carry in the down interference source tabulation and sacrifice the number of times that the descending interference sacrifice of the renewal request message of SS sign is sacrificed in the corresponding descending interference of neighbours BS with this descending interference, if in this timing length, this number of times is less than preset times, then this SS sign is sacrificed the corresponding descending interference of this neighbours BS sign the tabulation from descending interference and sacrifice in the SS identification list and delete, the number that SS is sacrificed in simultaneously that this neighbours BS sign is corresponding descending interference subtracts 1.
Step 511:BS judges whether the number of the descending interference sacrifice SS that this neighbours BS sign is corresponding is 0, if, execution in step 512; Otherwise, not dealing with, this flow process finishes.
This step also can be: BS judges whether the SS identification list is sacrificed in the corresponding descending interference of this neighbours BS sign is empty, if, execution in step 512; Otherwise, not dealing with, this flow process finishes.
The relevant information that neighbours BS is sacrificed in this descending interference in the tabulation is sacrificed in the descending interference of step 512:BS deletion self, comprising: the SS number is sacrificed in the IP address of this neighbours BS sign, this neighbours BS, the corresponding descending interference of this neighbours BS sign: 0.
If sacrificing to comprise in the tabulation, descending interference whether exist indication of descending interference sacrifice and descending interference to sacrifice neighbours' sum, and after carrying out this step, descending interference is sacrificed and is not comprised any neighbours BS sign in the tabulation, then described indicated value is made as 0, and described total value is made as 0; If after carrying out this step, descending interference is sacrificed and is also comprised neighbours BS sign in the tabulation, then described total value is subtracted 1.
Step 513:BS judges whether the down interference source of self comprises this neighbours BS sign in tabulating, if, not dealing with, this flow process finishes; Otherwise, execution in step 514.
Step 514:BS judges that tabulation is sacrificed in the descending interference of self and whether the down interference source tabulation does not comprise any neighbours BS sign, if, execution in step 515; Otherwise, execution in step 516.
Step 515:BS distributes down channel again, and this flow process finishes.
The descending neighbours that step 516:BS defines self system discharge, and the descending neighbours' sum according to current carries out the distribution of DSCH Downlink Shared Channel again, and carry out business according to the channel after distributing and transmit.
Among the present invention, also can preestablish one and upgrade duration, descending interference sacrifice neighbours BS every this upgrade duration to
It is pointed out that step 502～509 and step 510～516 there is no the branch of priority.

As shown in table 4, the tabulation of uplink interference sacrifice comprises: whether have uplink interference sacrifice neighbours indication; Uplink interference is sacrificed neighbours' sum; The corresponding relation of the identification list of these uplink interference sacrifice neighbours' of interference SS in the number of uplink interference sacrifice neighbours' BS sign, uplink interference sacrifice neighbours' IP address, these uplink interference sacrifice neighbours' of the interior interference of native system SS, the native system.
Here, whether having the number of these uplink interference sacrifice neighbours' of interference SS in the indication of uplink interference sacrifice, uplink interference sacrifice neighbours sum, the native system is optional parameters, and the initial value of this three parameter can be made as 0.
Among the present invention, the SS that disturbs this uplink interference to sacrifice neighbours in the native system abbreviates up sacrifice as and disturbs SS, then the number that disturbs this uplink interference to sacrifice neighbours' SS in the native system abbreviates the number that up sacrifice disturbs SS as, and the sign of disturbing this uplink interference to sacrifice neighbours' SS in the native system abbreviates the sign that up sacrifice disturbs SS as.
When this BS inserts, if neighbours BS receives the upward signal that the associated SS of this BS sends, then neighbours BS can send the renewal uplink interference sacrifice request message that carries the SS sign that neighbours BS identifies and this BS is associated to this BS, after this BS receives this message, neighbours BS sign is added in the tabulation of uplink interference sacrifice, and simultaneously that self is associated SS sign is added up sacrifice to and is disturbed in the SS identification list.
Step 602:BS receives the upward signal that the associated SS of neighbours BS sends in running, this signal carries neighbours BS sign, the IP address of neighbours BS, the associated SS sign of neighbours BS.
Step 603:BS judges whether the interference source in up going route of self comprises the neighbours BS sign that this message is carried in tabulating, if, execution in step 604; Otherwise, execution in step 606.
In this step, BS can whenever receive the upward signal that associated SS of neighbours BS sends, and just judges once in self the interference source in up going route tabulation whether comprise the neighbours BS sign that this message is carried, and carries out subsequent step according to judged result; Also can, preestablish a timing length, after each timing begins, write down the number of times of the upward signal that carries neighbours BS sign that each associated SS of each neighbours BS sends, if certain specific SS of in this timing length, receiving send at the number of times of the upward signal of certain particular neighbor BS sign greater than preset times, then judge in the interference source in up going route tabulation of body whether comprise this specific neighbours BS sign, and carry out subsequent step according to judged result.
Step 604:BS judges in the corresponding uplink interference SS identification list of this neighbours BS sign in the tabulation of self interference source in up going route whether comprise the SS sign that this message is carried, if, do not deal with, go to step 609; Otherwise, execution in step 605.
The SS sign that step 605:BS carries this message is added in the corresponding uplink interference SS identification list of this neighbours BS sign in self interference source in up going route tabulation, simultaneously, the corresponding uplink interference SS number of this neighbours BS sign in the interference source in up going route tabulation is added 1, go to step 609.
The SS number of the neighbours BS sign that step 606:BS carries this message, the IP address of neighbours BS, SS sign and uplink interference: 1 corresponding relation adds in the interference source in up going route tabulation of self.
If comprise whether there is the interference source in up going route indication in the interference source in up going route tabulation, and this indicated value is 0 before carrying out this step, then in this step, this indicated value is made as 1; If comprise interference source in up going route neighbours sum in the interference source in up going route tabulation, then in this step, this total value added 1.
Step 607:BS judges whether the uplink interference sacrifice of self comprises this neighbours BS sign in tabulating, if, do not deal with, go to step 609; Otherwise, execution in step 608.
Step 608:BS determines that self system has increased new up neighbours, carries out the assignment negotiation of up channel with current self up neighbours, and carries out channel allocation and professional transmission according to the channel allocation strategy after consulting.
Up neighbours comprise: interference source in up going route neighbours and uplink interference are sacrificed neighbours, if system's system is interference source in up going route neighbours and uplink interference sacrifice neighbours for native system, then this system is calculated as 1 neighbour calculating up neighbours' sum.
That step 609:BS detects is that a uplink interference SS not receiving in scheduled duration in the tabulation of self interference source in up going route sends, carry the upward signal that interference source in up going route neighbours BS corresponding with this uplink interference SS sign in the interference source in up going route tabulation identifies, delete in then that this interference source in up going route neighbours BS sign of this uplink interference SS sign from the interference source in up going route tabulation is the corresponding uplink interference SS identification list, the number of simultaneously that this interference source in up going route neighbours BS sign is corresponding uplink interference SS subtracts 1.
BS also can set a timing length, after each timing begins, each interference source in up going route neighbours BS in self interference source in up going route tabulation that detection is received sends, carry the number of times of the upward signal of uplink interference SS sign corresponding in the interference source in up going route tabulation with this neighbours BS sign, if in this timing length, this number of times is less than preset times, delete in then that this interference source in up going route neighbours BS sign of this SS sign from the interference source in up going route tabulation is the corresponding uplink interference SS identification list, simultaneously the corresponding uplink interference SS number of this interference source in up going route neighbours BS sign is subtracted 1.
Step 610:BS judges whether the SS sum of the uplink interference that this interference source in up going route neighbours BS sign is corresponding is 0, if, execution in step 611; Otherwise, not dealing with, this flow process finishes.
This step also can be: BS judges whether the corresponding uplink interference SS identification list of this interference source in up going route neighbours BS sign is empty, if, execution in step 611; Otherwise, not dealing with, this flow process finishes.

Fig. 7 be the uplink interference sacrifice neighbours that provide of the embodiment of the invention four increase, discharge and cause the flow chart that up channel distributes again, as shown in Figure 7, its concrete steps are as follows:
Step 701:BS initial access network detects the interference source in up going route neighbours and the uplink interference sacrifice neighbours of self system, and sets up the interference source in up going route tabulation and the uplink interference sacrifice is tabulated.
Step 702: in the BS running, neighbours BS receives the upward signal that the associated SS of this BS sends, and sends to this BS and upgrades up sacrifice request message, and this message is carried neighbours BS sign, the IP address of neighbours BS, the associated SS sign of this BS.
In this step, after neighbours BS receives the upward signal that the SS of this BS association sends, also can not send to this BS at once and upgrade uplink interference sacrifice request message, and just this BS sign is preserved as the interference source in up going route sign of self, when the renewal uplink interference sacrifice of predefined this BS arrives constantly, send to this BS and upgrade uplink interference sacrifice request message, record has sent to this BS and has upgraded the indication information that uplink interference is sacrificed request message simultaneously.
Step 703: this BS judges whether the uplink interference sacrifice of self comprises the neighbours BS sign that this message is carried in tabulating, if, execution in step 704; Otherwise, execution in step 707.
In this step, this BS can whenever receive the up sacrifice request message of renewal that neighbours BS sends, and just judges once in self the uplink interference sacrifice tabulation whether comprise the neighbours BS sign that this message is carried, and carries out subsequent step according to judged result; Also can, preestablish a timing length, after each timing begins, write down the number of times of the up sacrifice request message of renewal that carries the associated SS sign of this BS that each neighbours BS sends, if certain particular neighbor BS of in this timing length, receiving send at the number of times of the up sacrifice request message of renewal of certain specific SS sign greater than preset times, then judge in the uplink interference sacrifice tabulation of body whether comprise this specific neighbours BS sign, and carry out subsequent step according to judged result.
Step 704:BS judges the corresponding up sacrifice of this neighbours BS sign disturbs whether comprise the SS sign that this message is carried in the SS identification list in the tabulation of self uplink interference sacrifice, if, do not deal with, go to step 711; Otherwise, execution in step 705.
The corresponding up sacrifice of this neighbours BS sign that the SS sign that step 705:BS carries this message is added in self uplink interference sacrifice tabulation disturbs in the SS identification list, simultaneously, disturb the SS number to add 1 in the corresponding up sacrifice of this neighbours BS sign in the tabulation of uplink interference sacrifice.
Step 706:BS on self the uplink interference timesharing channel, to this SS transport service, goes to step 711 in Uplink Shared Channel.
In the Uplink Shared Channel with BS, be used for being called up noiseless timesharing channel, will be used for each BS and disturb the timesharing channel of SS transport service to be called the uplink interference timesharing channel of each BS to the up sacrifice of self to the timesharing channel of the SS transport service that is not subjected to any interference.
The SS number that the neighbours BS sign that step 707:BS carries this message, the IP address of neighbours BS, SS sign and up sacrifice disturb: 1 corresponding relation adds in the uplink interference sacrifice tabulation of self.
If comprise whether there is the indication of uplink interference sacrifice in the tabulation of uplink interference sacrifice, and this indicated value is 0 before carrying out this step, then in this step, this indicated value is made as 1; If comprise uplink interference sacrifice neighbours sum in the tabulation of uplink interference sacrifice, then in this step, this total value added 1.
Step 708:BS judges whether the interference source in up going route of self comprises this neighbours BS sign in tabulating, if, execution in step 709; Otherwise, execution in step 710.
Step 709:BS to this SS transport service, goes to step 711 on self uplink interference timesharing channel of Uplink Shared Channel.
Step 710:BS determines that self system has increased new up neighbours, carries out the assignment negotiation of up channel with current self up neighbours, and carries out channel allocation and professional transmission according to the channel allocation strategy after consulting.
Step 711:BS detect a up sacrifice of in scheduled duration, not receiving in the tabulation of self uplink interference sacrifice disturb that SS sends, carry in the tabulation of uplink interference sacrifice and should disturb SS to identify the up sacrifice request message of renewal that corresponding uplink interference sacrifice neighbours BS identifies by up sacrifice, then will this up sacrifice disturb SS sign this uplink interference from the tabulation of uplink interference sacrifice to sacrifice the corresponding up sacrifice of neighbours BS sign and disturb in the SS identification list and delete, simultaneously this uplink interference is sacrificed the corresponding up sacrifice of neighbours BS sign and disturb the number of SS to subtract 1.
BS also can set a timing length, after each timing begins, each uplink interference sacrifice neighbours BS in self uplink interference sacrifice tabulation that detection is received sends, carry the number of times that up sacrifice corresponding with this neighbours BS sign in the tabulation of uplink interference sacrifice disturbs the up sacrifice request message of renewal of SS sign, if in this timing length, this number of times is less than preset times, the up sacrifice of then this SS sign this uplink interference from the tabulation of uplink interference sacrifice being sacrificed neighbours BS sign correspondence disturbs in the SS identification list to be deleted, and simultaneously this uplink interference is sacrificed the corresponding up sacrifice interference SS number of neighbours BS sign and subtracts 1.
Step 712:BS judges whether the SS sum that the corresponding up sacrifice of this uplink interference sacrifice neighbours BS sign disturbs is 0, if, execution in step 713; Otherwise, not dealing with, this flow process finishes.
This step also can be: BS judges that the corresponding up sacrifice of this uplink interference sacrifice neighbours BS sign disturbs whether the SS identification list is empty, if, execution in step 713; Otherwise, not dealing with, this flow process finishes.
The relevant information that this uplink interference in the tabulation of step 713:BS deletion uplink interference sacrifice is sacrificed neighbours comprises: this uplink interference is sacrificed the IP address that neighbours BS identifies, this uplink interference is sacrificed neighbours BS, the up sacrifice that this uplink interference is sacrificed neighbours BS disturbs the SS number: 0.
Whether there are indication of uplink interference sacrifice and uplink interference sacrifice neighbours sum if comprise in the tabulation of uplink interference sacrifice, and after carrying out this step, do not comprise any neighbours BS sign in the tabulation of uplink interference sacrifice, then described indicated value is made as 0, described total value is made as 0; If after carrying out this step, also comprise neighbours BS sign in the tabulation of uplink interference sacrifice, then described total value is subtracted 1.
Step 714:BS judges whether interference source in up going route tabulation of self and the tabulation of uplink interference sacrifice do not comprise any neighbours BS sign, if, execution in step 715; Otherwise, execution in step 716.
Step 715:BS distributes down channel again, and this flow process finishes.
Step 716:BS judges whether the interference source in up going route of self comprises this neighbours BS sign in tabulating, if, not dealing with, this flow process finishes; Otherwise, execution in step 717.
