The user terminal that switches in other logic district is switched to the 3rd logic district.

Preferably, the 3rd logic district is identical with number and the coverage of first logic district.

The method that the embodiment of the invention provides, after being merged into second logic district by at least two first logic district with the carrier wave of corresponding same frequency, after the load of second logic district that gets access to reaches first thresholding, second logic district is split at least two the 3rd logic district, make after a plurality of first logic district are being merged, when the load of second logic district that can also obtain after merging is big second logic district is split, take into account the communication quality of network and the throughput of system, promoted the communication capacity of network.

Embodiment two

For the communication quality of taking into account network and the throughput of system, the embodiment of the invention provides a kind of method of cell networking, and the executive agent of this method can also can be other external system devices for the base station.For convenience of explanation, the embodiment of the invention is in conjunction with the content of above-described embodiment one, be at least two first logic district with residential quarter to be combined, user terminal is only in the coverage of a logic district, and spendable carrier wave is example for the corresponding carrier wave of logic district that this user terminal is positioned at only, and the method that present embodiment is provided is illustrated.Referring to Fig. 2, the method flow that present embodiment provides comprises:

201: at least two first logic district determining the carrier wave of corresponding same frequency.

Wherein, the corresponding carrier wave of each logic district in the network, and the carrier wave of a plurality of logic district correspondences can be same frequency.Therefore, when determining first logic district, can from a plurality of logic district of the carrier wave of corresponding same frequency, determine at least two first logic district according to pre-configured information.In addition, can also dynamically from a plurality of logic district of the carrier wave of corresponding same frequency, determine at least two first logic district according to actual conditions.For example, can be according to number of users, the RB(Resource Block of each logic district in a plurality of logic district of the carrier wave of corresponding same frequency, Resource Block) technical indicators such as utilance, utilization rate of air interface resource, throughput dynamically determine at least two first logic district from a plurality of logic district of the carrier wave of corresponding same frequency.For specifically selecting for use which kind of mode to determine at least two first logic district of carrier wave of corresponding same frequency and the quantity of definite first logic district, the embodiment of the invention does not all specifically limit at this.

Need to prove that at least two first logic district determining can be positioned under the same base station, also can be positioned under the different base stations, the embodiment of the invention does not limit at this.If at least two first logic district determining are positioned under the different base stations, then can pre-configured one of them base station as executive agent, also can select one of them base station as executive agent arbitrarily.Certainly, if executive agent is external system devices, then the base station that is positioned at of at least two first logic district of Que Dinging needs in advance the relevant information of each first logic district is sent to this external system devices.Wherein, the relevant information of first logic district comprises the frequency of the carrier wave of the first logic district correspondence at least.

202: the load total amount of obtaining the first definite logic district.

Wherein, the load total amount of first logic district of determining is the summation of the load of each first logic district, the load of each first logic district can be technical indicators such as the number of users of each first logic district, RB utilance, utilization rate of air interface resource, throughput, can also comprehensively determine according to above-mentioned a plurality of technical indicators.

In this step, if executive agent is the base station, then the base station can directly obtain the load total amount of the first definite logic district.If executive agent is external system devices, then the load total amount of first logic district that will be determined by the base station sends to external system devices, make external system devices directly obtain the load total amount of the first definite logic district thus, perhaps, the load of each first logic district that will be determined by the base station sends to external system devices, makes external system devices calculate the load total amount of the first definite logic district again according to the load of each first logic district.

203: after total amount is lower than second thresholding, first logic district of determining is merged into second logic district at load, wherein, the carrier wave of second logic district and the corresponding same frequency of first logic district.

At this step, if executive agent is the base station, then the base station can be after the load total amount be lower than second thresholding, and first logic district that directly will determine is merged into second logic district.If executive agent is external system devices, then external system devices need be after the load total amount be lower than second thresholding, send the instruction of execution merging to the base station, first logic district that will be determined according to the instruction of the execution merging that receives by the base station is merged into second logic district.

No matter executive agent is base station or external system devices, when the load total amount of first logic district of determining that step 201 gets access to is in certain threshold range, if first logic district that will determine merges, though the throughput of the system of second logic district after merging with merge before throughput compare decline, but because the load total amount in first logic district of determining is less, the decline of throughput of system can not impact the communication of the user terminal in first logic district of determining after merging.Therefore, in the time of can being lower than second thresholding in the load total amount of first logic district of determining, first logic district of determining is merged.In addition, again because load total amount meeting real-time change, enlarge markedly again after certain time point is lower than second thresholding for fear of the load total amount, present embodiment is when merging, except considering the situation of load overall control in second thresholding, also considered the load duration of total amount in second thresholding, therefore, can be lower than second thresholding in the load total amount of first logic district of determining, and the duration is just carried out the operation that first logic district that will determine is merged into second logic district after surpassing for second time.Wherein, second thresholding can arrange different numerical value according to the type difference of load total amount.For example, if the load total amount is total number of users, then second thresholding can be set to 10 or 20 etc.; If the load total amount is the RB utilance, then second thresholding can be set to 50% or 60%.Wherein, second time can be set to 10 minutes or 20 minutes etc. according to actual conditions, and the embodiment of the invention does not specifically limit this.

Further, in order to distinguish each logic district, and making the user terminal in each logic district can proper communication, the method that present embodiment provides also was included as the step of the second logic district allocating cell parameter before first logic district that will determine is merged into second logic district.Wherein, cell parameter includes but not limited to parameters such as cell ID, adjacent area parameter, channel parameter, transmitting power.Because the cell parameter of arbitrary first logic district can both be different from other logic district in the network, therefore, be that the cell parameter of second logic district configuration can be the cell parameter of arbitrary first logic district in first logic district of determining.In addition, the static cell parameter that can also set in advance for second logic district, perhaps the cell parameter for dynamically arranging is distinguished other logic district in second logic district and the network by the static cell parameter that sets in advance or the cell parameter that dynamically arranges.Wherein, in the specific implementation, static cell parameter is the pre-configured fixing cell parameter in base station, the cell parameter that the dynamically arranges cell parameter that to be the base station dynamically arrange according to the situation of cell layout in the network.

Need to prove, when not having user terminal in first logic district of determining, the load total amount of first logic district of determining is zero, if this moment, the load total amount still was lower than second thresholding, then directly first logic district that will determine of execution is merged into the operation of second logic district.When in first logic district of determining one or more user terminal being arranged, then when the load total amount is lower than second thresholding, before first logic district that will determine was merged into second logic district, the method that the embodiment of the invention provides also comprised the operation that user terminal is switched.Specifically comprise: the user terminal in each first logic district sends first search instruction of the information that carries second logic district, make user terminal in each first logic district according to the signal of communication of information search second logic district of second logic district of carrying in first search instruction, and behind the signal of communication that searches second logic district, switch to second logic district.Wherein, thus the information of second logic district is user terminal is used for the information that second logic district of recognition network is searched for the signal of communication of second logic district.The information of second logic district can comprise the cell ID of second logic district, the information such as frequency that can also comprise the second logic district correspondence, the embodiment of the invention specifically limits in the information of second logic district that this carries in not to first search instruction, and the signal of communication of information search second logic district that the user terminal in each first logic district can be by second logic district of carrying in first search instruction gets final product.

Because first logic district that also will not determine this moment is merged into second logic district, second logic district is not also arranged in the network, therefore, the user terminal in each first logic district can't search the signal of communication of second logic district when just beginning to search for.In the process of the signal of communication of information search second logic district of second logic district that the user terminal in each first logic district carries in according to first search instruction, can carry out the operation that first logic district that will determine is merged into second logic district.After merging was finished, the user terminal in each first logic district just can search the signal of communication of second logic district, and switches to second logic district behind the signal of communication that searches second logic district.

In order not influence the communications status of the user terminal in each first logic district, first logic district that needs to determine is merged into the shared time control of second logic district in the certain hour scope, therefore, first logic district of determining being merged into a shared time of second logic district switches less than system and holds time.Wherein, the time of the communications status that can keep terminal that is default of holding time is switched in system, switches and holds time if the time of terminal searching signal of communication surpasses system, and then the communications status of terminal probably is interrupted.It specifically can be to switch in the system to keep the time that timer T304 sets that system's switching is held time, its size can be set to 500ms～2s according to actual conditions, can also be the other times size, the embodiment of the invention is not switched the size of holding time to system at this and is specifically limited.

In the specific implementation, first logic district of determining is merged into second logic district, refer to the base station by adjusting inner parameter setting, as second logic district, and make second logic district use the cell parameter of configuration first logic district determined.

For instance, shown in Fig. 3 (a), first logic district of determining with step 201 is that first logic district 1, first logic district 2 and first logic district 3 are that example describes.The load total amount of first logic district 1, first logic district 2 and first logic district 3 that gets access in step 202 is lower than second thresholding, and the duration is above after second time, user terminal A and B, first logic district, 2 interior user terminal C and D, first logic district, 3 interior user terminal E in first logic district 1 send first search instruction of the information that carries second logic district, and in user terminal A, B, C, D and E search procedure first logic district 1, first logic district 2 and first logic district 3 are merged into second logic district.After merging is finished, user terminal E in user terminal C in user terminal A in first logic district 1 and B, first logic district 2 and D, first logic district 3 searches the signal of communication of second logic district, and switch to second logic district, obtain the schematic diagram shown in Fig. 3 (b).

After user terminal in each first logic district switches to second logic district, the user terminal that switches to second logic district all uses the cell parameter of second logic district to communicate, and spendable carrier wave is the corresponding carrier wave of second logic district, and this carrier wave is same frequency with merging the corresponding carrier wave of preceding first logic district.

In addition, when uplink communication, according to the channel quality of the user terminal that sends data, select can a plurality of base stations in second logic district one to receive the best base station of signal and be used for receiving the data that user terminal sends, make the signal of the data that receive strengthen; When downlink communication, each base station in second logic district sends identical data simultaneously to user terminal, makes the signal of the data that user terminal receives strengthen.Therefore, first logic district of determining is merged into second logic district after, improved the communication quality of network.

Can realize that by above-mentioned steps 201 to step 203 residential quarter merges networking, but because the throughput of system descends after merging, in order in the communication quality that improves network, to take into account the throughput of system, when the load of second logic district that obtains after merging increases, can also further take the mode that splits, to improve the throughput of system, concrete fractionation mode sees following steps for details.

204: the load that obtains second logic district.

Wherein, the load of second logic district can be technical indicators such as the number of users of second logic district, RB utilance, utilization rate of air interface resource, throughput, can also comprehensively determine according to above-mentioned a plurality of technical indicators.

In this step, if executive agent is the base station, then the base station can directly obtain the load of second logic district.If executive agent is external system devices, then can get access to the load of second logic district by the base station after, send it to external system devices, make external system devices get access to the load of second logic district thus.

205: after the load of second logic district reaches first thresholding, second logic district is split at least two the 3rd logic district, wherein, the carrier wave of each the 3rd logic district and the corresponding same frequency of first logic district.

Wherein, the number that splits the 3rd logic district that obtains can be identical with the number of first logic district, and the coverage of each the 3rd logic district is identical with the coverage of each first logic district.Certainly, the number of the 3rd logic district also can be different with the number of first logic district.The coverage of each the 3rd logic district can also can be different with the coverage of each first logic district, and the embodiment of the invention does not specifically limit at this.

At this step, if executive agent is the base station, after then the base station can reach first thresholding at the load of second logic district, directly second logic district is split at least two the 3rd logic district.If executive agent is external system devices, after then external system devices need reach first thresholding at the load of second logic district, send the instruction of execution fractionation to the base station, according to the instruction that the execution that receives splits second logic district is split at least two the 3rd logic district by the base station.

No matter executive agent is base station or external system devices, because first logic district that will determine is merged into after second logic district, the throughput of system of second logic district is compared with the throughput before the merging and has been descended, therefore, when the load of second logic district that gets access to when step 204 reaches first thresholding, second logic district need be split, unaffected with the data communication that guarantees system.In addition, again because the load of second logic district meeting real-time change, significantly reduce again after certain time point reaches first thresholding for fear of load, the embodiment of the invention is when splitting, except the load of considering second logic district reaches the situation of first thresholding, considered that also the load of second logic district reaches the duration of first thresholding.Therefore, need reach first thresholding at the load of second logic district, and after the duration surpassed the very first time, just execution split into second logic district operation of at least two the 3rd logic district.Wherein, first thresholding is can be according to the type of the load of second logic district different arranges different numerical value.For example, if the load of second logic district is total number of users, then first thresholding can be set to 50 or 100 etc.; If the load of second logic district is the RB utilance, then first thresholding can be set to 80% or 90%.Wherein, the very first time can be set to 10 minutes or 20 minutes etc. according to actual conditions, and the embodiment of the invention does not specifically limit this.

Further, in order to distinguish each logic district, and make the user terminal in each logic district can proper communication, the method that present embodiment provides also was included as the step of each the 3rd logic district allocating cell parameter before second logic district is split at least two the 3rd logic district.Wherein, cell parameter includes but not limited to: parameters such as cell ID, adjacent area parameter, channel parameter, transmitting power.Each the 3rd logic district can be the static cell parameter that sets in advance, be the cell parameter that dynamically arranges perhaps, thereby by the static cell parameter that sets in advance or the cell parameter that dynamically arranges other logic district in each the 3rd logic district and the network distinguished.In addition, because the cell parameter of second logic district also can be different from other logic district in the network, but the cell parameter of second logic district has only one, therefore can select the cell parameter of one of them the 3rd logic district is the cell parameter of second logic district, and the cell parameter of other the 3rd logic district is the static cell parameter that sets in advance or the cell parameter that dynamically arranges.In addition, can also adopt other modes is each the 3rd logic district allocating cell parameter, for example can dispose the cell parameter of the 3rd logic district according to the cell parameter of first logic district, and when the number of the 3rd logic district during smaller or equal to first logic district, can also from the cell parameter of first logic district, select the cell parameter identical with the number of the 3rd logic district respectively as the cell parameter of each the 3rd logic district arbitrarily.When the number of the 3rd logic district during greater than first logic district, can be with the cell parameter of each first logic district respectively as the cell parameter of each the 3rd logic district, and set in advance static cell parameter or dynamically arrange cell parameter for other the 3rd logic district.Be each the 3rd logic district allocating cell parameter for which kind of mode of concrete employing, the embodiment of the invention does not specifically limit at this.

Need to prove that after the load of second logic district reached first thresholding, before second logic district was split at least two the 3rd logic district, the method that the embodiment of the invention provides also comprised the operation that user terminal is switched.Specifically comprise: the user terminal in second logic district sends second search instruction of the information that carries the 3rd logic district, make user terminal in second logic district according to the signal of communication of information search the 3rd logic district of the 3rd logic district of carrying in second search instruction, and behind the signal of communication that searches the 3rd logic district, switch to the 3rd logic district.Wherein, thus the information of the 3rd logic district is user terminal is used for the information that the 3rd logic district of recognition network is searched for the signal of communication of the 3rd logic district.The information of the 3rd logic district can comprise the cell ID of the 3rd logic district, the information such as frequency that can also comprise the 3rd logic district correspondence, the embodiment of the invention specifically limits in the information of the 3rd logic district that this carries in not to second search instruction, and the signal of communication of information search the 3rd logic district that the user terminal in second logic district can be by the 3rd logic district of carrying in first search instruction gets final product.Can be according to the coverage condition that be about to split the 3rd logic district that obtains, the information of the 3rd logic district of carrying in second search instruction that the user terminal in second logic district sends is the information that is about to cover the 3rd logic district of this user terminal.Therefore, the 3rd logic district that switches to of the user terminal in second logic district is for covering the 3rd logic district of this user terminal.

Because also do not split into second logic district at least two the 3rd logic district this moment, and the 3rd logic district is not also arranged in the network, therefore, the user terminal in second logic district can't search the signal of communication of the 3rd logic district when just beginning to search for.User terminal in second logic district is searched in the process of signal of communication of the 3rd logic district, can carry out the operation that second logic district is split at least two the 3rd logic district.After fractionation was finished, the user terminal in second logic district can search the signal of communication of the 3rd logic district, and switched to the 3rd corresponding logic district behind the signal of communication that searches the 3rd logic district.

In order not influence the communications status of the user terminal in second logic district, second logic district need be split into the shared times control of at least two the 3rd logic district in the certain hour scope, therefore, second logic district being split into the shared times of at least two the 3rd logic district switches less than system and holds time.Wherein, system's switching is held time to refer to switch in the system and is kept the time that timer T304 sets, its size can be set to 500ms～2s according to actual conditions, can also be the other times size, and the embodiment of the invention is not switched the size of holding time to system at this and specifically limited.

In the specific implementation, second logic district is split at least two the 3rd logic district, refer to that the base station by adjusting inner parameter setting, is split as at least two the 3rd logic district with second logic district, and make each the 3rd logic district use the cell parameter of configuration.

For instance, shown in Fig. 3 (c), still with in the step 203 with first logic district 1, it is that example describes that first logic district 2 and first logic district 3 are merged into second logic district, the load of second logic district that gets access in step 204 reaches first thresholding, and the duration is above after the very first time, user terminal A in second logic district, B sends second search instruction of the information that carries the 3rd logic district 1, user terminal C in second logic district, D and E send second search instruction of the information that carries the 3rd logic district 2, and in user terminal A, B, C, in D and the E search procedure second logic district is split as the 3rd logic district 1 and the 3rd logic district 2.After fractionation is finished, user terminal A, B in second logic district searches the signal of communication of the 3rd logic district 1, and user terminal C, the D and the E that switch in the 3rd logic district 1, the second logic district search the signal of communication of the 3rd logic district 2, and switch to the 3rd logic district 2.

After user terminal in second logic district switches to the 3rd logic district, the user terminal that switches to the 3rd logic district all uses the cell parameter of the 3rd logic district to communicate, and spendable carrier wave is the corresponding carrier wave of the 3rd logic district, and this carrier wave is same frequency with merging the corresponding carrier wave of preceding first logic district.

In addition, after second logic district was split, the sum of logic district increased in the network, and the user terminal that is positioned at the logic district edge increases, and made network integrated communication quality descend.In order to improve the communication quality of network, after second logic district is split as at least two the 3rd logic district, can also adopt CoMP(Coordinated Multiple Points, multipoint cooperative) technology improves the communication quality of the user terminal at the 3rd logic district edge.

Particularly, when uplink communication, the base station of the 3rd logic district receives the data of the user terminal transmission at the 3rd logic district edge, the base station of other simultaneously adjacent with the 3rd logic district logic district also receives the data of the user terminal transmission at the 3rd logic district edge, and the data collaborative that the user terminal at the 3rd logic district edge sends sent to the base station of the 3rd logic district, make the signal of the data that the base station of the 3rd logic district receives strengthen; When downlink communication, when the base station of the 3rd logic district sends the data to the user terminal at the 3rd logic district edge, also send to the base station of other logic district adjacent with the 3rd logic district, by the collaborative user terminal that sends the data to the 3rd logic district edge in the base station of other logic district, make the user terminal at the 3rd logic district edge receive the signal enhancing of data.Therefore, though the throughput for taking into account system, need when the load of second logic district is big, second logic district be split as at least two the 3rd logic district, make the communication quality of network decrease, but by using the CoMP technology in the 3rd logic district after fractionation, also can improve the communication quality of the network that is lowered after the fractionation effectively.

In the specific implementation, can continue to carry out above-mentioned steps 201 to step 205 according to the situation of loading in the network, adjust the mode of cell networking in real time, when taking into account the throughput of system, optimize the communication quality of network.In addition, in having a panel region of a plurality of logic district, can a plurality of first logic district be merged at least two second logic district respectively according to above-mentioned steps 201 to step 205, again each second logic district is split and become at least two the 3rd logic district, be implemented in and carry out the merging of logic district and the fractionation of logic district in the panel region simultaneously, when taking into account throughput of system, the whole network communication quality that improves in this panel region.Wherein, specifically which first logic district is merged into second logic district, and after merging second logic district is split into several the 3rd logic district, can determine according to pre-configured information, also can dynamically determine according to actual conditions.The carrier wave of second logic district and the corresponding same frequency of first logic district that is merged into second logic district, the carrier wave of the second different logic district correspondences can be same frequency, also can be different frequency, and, the 3rd logic district and the carrier wave that splits the corresponding same frequency of second logic district before.

In sum, the method that the embodiment of the invention provides, after being merged into second logic district by at least two first logic district with the carrier wave of corresponding same frequency, after the load of second logic district that gets access to reaches first thresholding, second logic district is split at least two the 3rd logic district, make after a plurality of first logic district are being merged, when the load of second logic district that can also obtain after merging is big second logic district is split, take into account the communication quality of network and the throughput of system, promoted the communication capacity of network.And, in communication process, can also continue to change the networking mode of residential quarter, continue namely to carry out that the residential quarter merges and the residential quarter fractionation, thereby can change the networking mode of residential quarter according to the variation of system situation in real time, use comparatively flexible.

Embodiment three

For the communication quality of taking into account network and the throughput of system, the embodiment of the invention provides a kind of method of cell networking, and the executive agent of this method can also can be other external system devices for the base station.For convenience of explanation, the embodiment of the invention is in conjunction with the content of above-described embodiment one, be at least two first logic district with residential quarter to be combined, user terminal is in the coverage of a plurality of logic district, and spendable carrier wave is example for the corresponding a plurality of carrier waves of a plurality of logic district that this user terminal is positioned at, and the method that present embodiment is provided is illustrated.Referring to Fig. 4, the method flow that the embodiment of the invention provides comprises:

401: at least two first logic district determining the carrier wave of corresponding same frequency.

Wherein, the corresponding carrier wave of each logic district in the network, and the carrier wave of a plurality of logic district correspondences can be same frequency.Therefore, when determining first logic district, can from a plurality of logic district of the carrier wave of corresponding same frequency, determine at least two first logic district according to pre-configured information.In addition, can also dynamically from a plurality of logic district of the carrier wave of corresponding same frequency, determine at least two first logic district according to actual conditions.For example, can dynamically from a plurality of logic district of the carrier wave of corresponding same frequency, determine at least two first logic district according to technical indicators such as the number of users of each logic district in a plurality of logic district of the carrier wave of corresponding same frequency, RB utilance, utilization rate of air interface resource, throughputs.For specifically selecting for use which kind of mode to determine at least two first logic district of carrier wave of corresponding same frequency and the quantity of definite first logic district, the embodiment of the invention does not all specifically limit at this.

402: the load total amount of obtaining the first definite logic district.

Need to prove that when not having user terminal in first logic district of determining, the load total amount of the first definite logic district is zero, if this moment, the load total amount still was lower than second thresholding, then need not execution in step 403, but continue to carry out subsequent step 404.When in first logic district of determining one or more user terminal being arranged, then after the load total amount was lower than second thresholding, the method that the embodiment of the invention provides also comprised the step 403 that user terminal is switched.

403: after the load total amount is lower than second thresholding, the user terminal in first logic district of determining is switched to other logic district from first logic district of determining.

Wherein, because user terminal is within the coverage of a plurality of logic district in embodiments of the present invention, therefore the user terminal in first logic district of determining is except the coverage of first logic district, also in the coverage of other logic district, other logic district that cover the user terminal in first logic district can be for one or more, other logic district of user terminal in first logic district of cover determining and definite first logic district can corresponding same frequency carrier wave, carrier wave that also can corresponding different frequency.Because when two logic district are adjacent logic district, when the carrier wave of the corresponding same frequencys of these two logic district, the user terminal that is positioned at the edge of one of them logic district also can be thought and covered by another logic district, can switch to another logic district.Therefore, when the carrier wave of at least one logic district and the definite corresponding same frequency of first logic district is arranged in other logic district of the user terminal in first logic district of cover determining, the user terminal that is positioned at the edge of the first definite logic district can be switched to other logic district with the carrier wave of the corresponding same frequency of determining of first logic district, and other user terminals in first logic district that will determine switch to other logic district with the carrier wave of definite corresponding different frequency of first logic district.

At this step, if executive agent is the base station, then the base station can directly switch to other logic district with user terminal from first logic district of determining after the load total amount is lower than second thresholding.If executive agent is external system devices, then external system devices need be after the load total amount be lower than second thresholding, send the instruction of execution switching to the base station, the instruction of being switched according to the execution that receives by the base station switches to other logic district with user terminal from first logic district of determining.

No matter executive agent is base station or external system devices, because the user terminal in first logic district of determining is in the coverage of a plurality of logic district.Therefore, after the load total amount that step 402 gets access to is lower than second thresholding, can not carry out the step that first logic district that will determine is merged into second logic district earlier, but the user terminal of first logic district that first execution will be determined switches to the step of other logic district, the user terminal of first logic district of make determining can continue to keep communications status in other logic district, the phenomenon of communications status interruption can not appear in the user terminal that ensures first logic district of determining in first logic district that will determine is merged into the process of second logic district.Wherein, be a plurality of if cover other logic district of user terminal, then user terminal can other logic district of arbitrary selection switch.In addition, because load total amount meeting real-time change, enlarge markedly again after certain time point is lower than second thresholding for fear of the load total amount, except considering the situation of load overall control in second thresholding, also consider the load duration of total amount in second thresholding, therefore, can be lower than second thresholding in the load total amount of first logic district of determining, and the duration, the user terminal of just carrying out first logic district of determining switched to the operation of other logic district above after second time.Wherein, second thresholding can arrange different numerical value according to the type difference of load total amount.For example, if the load total amount is total number of users, then second thresholding can be set to 10 or 20 etc.; If the load total amount is the RB utilance, then second thresholding can be set to 50% or 60%.Wherein, second time can be set to 10 minutes or 20 minutes etc. according to actual conditions, and the embodiment of the invention does not specifically limit this.

For instance, shown in Fig. 5 (a), first logic district of the carrier wave of the corresponding same frequency of determining with step 401 is that first logic district 1, first logic district 2 and first logic district 3 are that example describes.The load total amount of first logic district 1, first logic district 2 and first logic district 3 that gets access in step 402 is lower than second thresholding, and after the duration surpassed for second time, the user terminal A of first logic district 1 switched to cover in the user terminal A logic district 4; The user terminal B of first logic district 1 is switched in the covering user terminal B logic district 5; User terminal C and the D of first logic district 2 are switched in covering user terminal C and the D logic district 6; The user terminal E of first logic district 3 is switched in the covering user terminal E logic district 7, shown in Fig. 5 (b).

404: first logic district that will determine is merged into second logic district, wherein, and the carrier wave of second logic district and the corresponding same frequency of first logic district.

Further, in order to distinguish each logic district, and making the user terminal in each logic district can proper communication, the method that present embodiment provides also was included as the step of the second logic district allocating cell parameter before first logic district that will determine is merged into second logic district.Wherein, cell parameter includes but not limited to: parameters such as cell ID, adjacent area parameter, channel parameter, transmitting power.Because the cell parameter of arbitrary first logic district can both be different from other logic district in the network, therefore, the cell parameter of second logic district configuration can be the cell parameter of arbitrary first logic district in first logic district of determining.In addition, can also be the static cell parameter that sets in advance, perhaps the cell parameter for dynamically arranging in the process of carrying out the embodiment of the invention is distinguished other logic district in second logic district and the network by the static cell parameter that sets in advance or the cell parameter that dynamically arranges.Wherein, static cell parameter is the pre-configured fixing cell parameter in base station, and the cell parameter that dynamically arranges is the cell parameter that the base station dynamically arranges according to the situation of cell layout in the network in the specific implementation.

405: the user terminal that will switch in other logic district switches to second logic district.

At this step, if the executive agent of step 404 is the base station, then the operation that the user terminal that will switch in this step in other logic district switches to second logic district can directly be carried out in the base station.If the executive agent of step 404 is external system devices, after externally system equipment need send the instruction that carry out to merge and is merged into second logic district to the base station and by first logic district that the base station carries out determining, the base station will be continued to carry out the user terminal that will switch in this step in other logic district and be switched to second logic district.

Particularly, can all or part of user terminal that switch in other logic district be switched to second logic district according to the load of other logic district, thereby reach the purpose of the load of balanced second logic district and other logic district.For example, if the load of other logic district surpasses certain threshold range, whole user terminals that then will switch in other logic district switch to second logic district, certain customers' terminal that perhaps will switch in other logic district switches to second logic district, makes the load of other logic district remain within this threshold range.

In addition, the user terminal in will switching to other logic district switches to second logic district, also original the or initiate user terminal of other logic district can be switched to second logic district and switch to second logic district.

After user terminal in will switching to other logic district switches to second logic district, the user terminal that switches to second logic district all uses the cell parameter of second logic district to communicate, and spendable carrier wave is the corresponding carrier wave of second logic district, and this carrier wave is same frequency with merging the corresponding carrier wave of preceding first logic district.

For instance, after step 404 is merged into second logic district with first logic district 1, first logic district 2 and first logic district 3, the user terminal A that switches in the logic district 4 is switched to second logic district; The user terminal B that switches in the logic district 5 is switched to second logic district; The user terminal C and the D that switch in the logic district 6 are switched to second logic district; The user terminal E that switches in the logic district 7 is switched to second logic district, obtain the schematic diagram shown in Fig. 5 (c).

In addition, the user terminal in will switching to other logic district switches to after second logic district, and user terminal is identical with the mode that above-described embodiment two provides in the mode of the uplink communication of second logic district and downlink communication, gives unnecessary details at this again.

Can realize that by above-mentioned steps 401 to step 405 residential quarter merges networking, but because the throughput of system descends after merging, in order in the communication quality that improves network, to take into account the throughput of system, when the load of second logic district that obtains after merging increases, can also further take the mode that splits, to improve the throughput of system, concrete fractionation mode sees following steps for details.

406: the load that obtains second logic district.

407: after the load of second logic district reaches first thresholding, the user terminal in second logic district is switched to other logic district from second logic district.

Wherein, because user terminal is within the coverage of a plurality of logic district in embodiments of the present invention, therefore the user terminal in second logic district is except the coverage of second logic district, also in the coverage of other logic district, other logic district that cover the user terminal in second logic district can be for one or more, cover other logic district of the user terminal in second logic district and the carrier wave of the corresponding same frequency of second logic district, carrier wave that also can corresponding different frequency.Because when two logic district are adjacent logic district, when the carrier wave of the corresponding same frequencys of these two logic district, the user terminal that is positioned at the edge of one of them logic district also can be thought and covered by another logic district, can switch to another logic district.Therefore, when the carrier wave of at least one logic district and the corresponding same frequency of second logic district is arranged in other logic district of the user terminal in covering second logic district, the user terminal that is positioned at the edge of second logic district can be switched to other logic district with the carrier wave of the corresponding same frequency of second logic district, and other user terminals in second logic district are switched to other logic district with the carrier wave of the corresponding different frequency of second logic district.

At this step, if executive agent is the base station, after then the base station can reach first thresholding at the load of second logic district, directly user terminal is switched to other logic district from second logic district.If executive agent is external system devices, after then external system devices need reach first thresholding at the load of second logic district, send the instruction of execution switching to the base station, the instruction of being switched according to the execution that receives by the base station switches to other logic district with user terminal from second logic district.

No matter executive agent is base station or external system devices, because the user terminal in second logic district is in a plurality of logic district coverages, then user terminal can use the corresponding a plurality of carrier waves of a plurality of logic district that cover this user terminal.Therefore, step 406 obtain to the load of second logic district when reaching first thresholding, can not carry out the step that second logic district is split at least two the 3rd logic district earlier, but carry out the user terminal in second logic district is switched to the step of other logic district from second logic district, thereby make the user terminal of the first definite logic district can in other logic district, continue to keep communications status.Wherein, be a plurality of if cover other logic district of user terminal, then user terminal can be switched to arbitrary other logic district.In addition, again because the load of second logic district meeting real-time change, significantly reduce again after certain time point is lower than certain threshold range for fear of load, the embodiment of the invention is when switching to user terminal other logic district that cover user terminal from second logic district, reach the situation of first threshold range except the load of considering second logic district, considered that also the load of second logic district reaches the duration of first thresholding, therefore, need reach first thresholding at the load of second logic district, and the duration is just carried out the operation that the user terminal in second logic district is switched to other logic district from second logic district after surpassing the very first time.Wherein, first thresholding is can be according to the type of the load of second logic district different arranges different numerical value.For example, if the load of second logic district is total number of users, then first thresholding can be set to 50 or 100 etc.; If the load of second logic district is the RB utilance, then first thresholding can be set to 80% or 90%.Wherein, the very first time can be set to 10 minutes or 20 minutes etc. according to actual conditions, and the embodiment of the invention does not specifically limit this.

For instance, the load that gets access to second logic district in step 406 reaches first thresholding, and the duration is above after the very first time, because the load of logic district 4 in certain threshold range, then switches to the user terminal A of second logic district logic district 4 of covering user terminal A; Similarly, the user terminal B with second logic district switches to the logic district 5 that covers user terminal B; User terminal C and the D of second logic district are switched to the logic district 6 that covers user terminal C and D; The user terminal E of second logic district is switched to the logic district 7 that covers user terminal E, obtain the schematic diagram shown in Fig. 5 (d).

In addition, after the user terminal in second logic district is switched to other logic district from second logic district, the step 408 that second logic district is split at least two the 3rd logic district can be directly carried out, the step that second logic district is split at least two the 3rd logic district can also be determined whether to carry out according to the load condition of other logic district.Specifically comprise: obtain the load of other logic district, after the load of each other logic district reaches the 3rd thresholding, carry out the step 408 that second logic district is split at least two the 3rd logic district.

Wherein, other logic district can be for one or more, when other logic district when being a plurality of, need obtain the load of each other logic district.The load of each other logic district can be technical indicators such as the number of users of each other logic district, RB utilance, utilization rate of air interface resource, throughput, can also comprehensively determine according to above-mentioned a plurality of technical indicators.Before second logic district is split at least two the 3rd logic district, except the load of considering other logic district reaches the situation of the 3rd thresholding, consider that also the load of other logic district reaches the duration of the 3rd thresholding.Therefore, need reach the 3rd thresholding at the load of second logic district, and after the duration reached for the 3rd time, just carry out the operation that second logic district is split at least two the 3rd logic district.Wherein, the 3rd thresholding is can be according to the type of the load of second logic district different arranges different numerical value.For example, if the load of second logic district is total number of users, then the 3rd thresholding can be set to 50 or 100 etc.; If the load of second logic district is the RB utilance, then the 3rd thresholding can be set to 80% or 90%.Wherein, the 3rd time can be set to 10 minutes or 20 minutes etc. according to actual conditions, and the embodiment of the invention does not specifically limit this.

408: second logic district is split at least two the 3rd logic district, wherein, the carrier wave of each the 3rd logic district and the corresponding same frequency of first logic district.

At this step, if executive agent is the base station, then the base station can directly split into second logic district at least two the 3rd logic district, then external system devices need send the instruction that carry out to split to the base station, according to the instruction that the execution that receives splits second logic district is split at least two the 3rd logic district by the base station.

If after in step 407, user terminal being switched to other logic district from second logic district, judge the load condition of other logic district again, and after reaching the 3rd thresholding, just carries out the load of other logic district the operation that second logic district is split at least two the 3rd logic district, then user terminal is being reached the process of the 3rd thresholding from the load that second logic district switches to other logic district and other logic district, second logic district may increase user terminal newly, therefore after the load of other logic district reaches the 3rd thresholding, after also needing earlier the user terminal that increases newly in second logic district to be switched to other logic district, again second logic district is split at least two the 3rd logic district.By before second logic district is split at least two the 3rd logic district, whole user terminals of second logic district all being switched to other logic district, make whole user terminals of second logic district to keep communications status in other logic district, the user terminal that ensures second logic district phenomenon that communications status interrupts can not occur in second logic district splits into the process of at least two the 3rd logic district.

Need to prove, second logic district is split at least two the 3rd logic district, refer to that the base station by adjusting inner parameter setting, is split as at least two the 3rd logic district with second logic district, and make each the 3rd logic district use the cell parameter of configuration.

409: the user terminal that will switch in other logic district switches to the 3rd logic district.

Particularly, can the 3rd logic district that the interior user terminal of other logic district switches to this user terminal self geographic area, place correspondence will be switched to.If the coverage of the 3rd logic district after splitting is identical with the coverage of the first original logic district, then the 3rd logic district that switches to of user terminal is identical with the first original logic district; If the coverage of the 3rd logic district after splitting is different with the coverage of the first original logic district, then the user still switches to the 3rd logic district that can cover this user terminal.

In this step, switch to the 3rd logic district and can comprise switching to user terminal in other logic district: according to the load of other logic district, all or part of user terminal that switches in other logic district is switched to the 3rd corresponding logic district.For example, if the load of other logic district reaches certain threshold range, the user terminal that then will switch in other logic district all switches to the 3rd corresponding logic district, certain customers' terminal that perhaps will switch in other logic district switches to the 3rd corresponding logic district, makes the load of other logic district remain within this threshold range.In addition, the original or initiate user terminal of other logic district can also be switched to second logic district.

For instance, after step 408 is split as second logic district the 3rd logic district 1 and the 3rd logic district 2, the user terminal A that switches in the logic district 4 is switched to the 3rd logic district 1; The user terminal B that switches in the logic district 5 is switched to the 3rd logic district 1; The user terminal C and the D that switch in the logic district 6 are switched to the 3rd logic district 2; The user terminal E that switches in the logic district 7 is switched to the 3rd logic district 2, obtain the schematic diagram shown in Fig. 5 (e).

In this step, if the executive agent of step 408 is the base station, then the operation that the user terminal that will switch in this step in other logic district switches to the 3rd logic district can directly be carried out in the base station.If the executive agent of step 408 is external system devices, after externally system equipment need send the order that carry out to split and carries out second logic district split at least two the 3rd logic district to the base station and by the base station, the operation that the user terminal that will switch in this step in other logic district switches to the 3rd logic district will be continued to carry out in the base station.

After user terminal in will switching to other logic district switches to the 3rd logic district, the user terminal that switches to the 3rd logic district all uses the cell parameter of the 3rd logic district to communicate, and spendable carrier wave is the corresponding carrier wave of the 3rd logic district, and this carrier wave is same frequency with merging the corresponding carrier wave of preceding first logic district.

In addition, the user terminal in will switching to other logic district switches to after the 3rd logic district, and the mode of the uplink communication of user terminal in the 3rd logic district and downlink communication is identical with the mode that above-described embodiment two provides, and gives unnecessary details at this again.
