Embodiment two

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

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

Wherein, the corresponding carrier wave in each logic district in network, and carrier wave corresponding to multiple logic district can be same frequency.Therefore, when determining the first logic district, it is possible to determine at least two the first logic district according to the information being pre-configured with from multiple logic district of the carrier wave of corresponding same frequency.In addition to this it is possible to dynamically determine at least two the first logic district from multiple logic district of the carrier wave of corresponding same frequency according to practical situation.Such as, dynamically at least two the first logic district can be determined from multiple logic district of the carrier wave of corresponding same frequency according to the technical specification such as the number of users of each logic district, RB (ResourceBlock, Resource Block) utilization rate, utilization rate of air interface resource, handling capacity in multiple logic district of the carrier wave of corresponding same frequency.For specifically selecting at least two first logic district of carrier wave which kind of mode determines corresponding same frequency and the quantity of the first logic district determined, the embodiment of the present invention does not all specifically limit at this.

It should be noted that at least two the first logic district determined may be located under same base station, it is also possible to being positioned under different base stations, the embodiment of the present invention is not defined at this.If it is determined that at least two the first logic district be positioned under different base stations, then can be pre-configured with one of them base station as executive agent, it is also possible to arbitrarily select one of them base station as executive agent.Certainly, if executive agent is external system devices, it is determined that the base station that is positioned at, at least two the first logic district need in advance the relevant information of each first logic district to be sent to this external system devices.Wherein, the relevant information of the first logic district at least includes the frequency of carrier wave corresponding to the first logic district.

202: obtain the load total amount of the first logic district determined.

Wherein, the load total amount of the first logic district determined is the summation of the load of each first logic district, the load of each first logic district can be the technical specifications such as the number of users of each first logic district, RB utilization rate, utilization rate of air interface resource, handling capacity, it is also possible to comprehensively determines according to above-mentioned multiple technical specifications.

In this step, if executive agent is base station, then base station can directly obtain the load total amount of the first logic district determined.If executive agent is external system devices, then by base station, the load total amount of the first logic district determined is sent to external system devices, external system devices is made thus directly to obtain the load total amount of the first logic district determined, or, by base station, the load of each first logic district determined is sent to external system devices, makes external system devices obtain the load total amount of the first logic district determined further according to the carry calculation of each first logic district.

203: after load total amount is lower than the second thresholding, it is to be determined to the first logic district be merged into second logic district, wherein, the carrier wave of the second logic district and the first corresponding same frequency in logic district.

For this step, if executive agent is base station, then the first logic district determined after load total amount is lower than the second thresholding, directly can be merged into second logic district by base station.If executive agent is external system devices, then external system devices needs after load total amount is lower than the second thresholding, send the instruction performing to merge to base station, base station according to the instruction performing to merge received, the first logic district determined is merged into second logic district.

No matter executive agent is base station or external system devices, when load total amount in the first logic district of the determination that step 201 gets is in certain threshold range, if the first logic district determined is merged, although the decline compared with the handling capacity before merging of the handling capacity of the system of the second logic district after merging, but owing to the load total amount in the first logic district of determining is less, after merging, the communication on the user terminal in the first logic district determined that declines of throughput of system does not result in impact.Therefore, can when the load total amount of the first logic district determined be lower than the second thresholding, it is to be determined to the first logic district merge.Additionally, again due to load total amount meeting real-time change, in order to avoid load total amount enlarges markedly again after certain time point is lower than the second thresholding, the present embodiment is when merging, except considering load overall control situation in the second thresholding, also contemplate the load total amount persistent period in the second thresholding, therefore, can in the load total amount of the first logic district determined lower than the second thresholding, and the persistent period is more than, after the second time, just performing to be merged into the first logic district determined the operation of one the second logic district.Wherein, the second thresholding can arrange different numerical value according to the type difference of load total amount.Such as, if load total amount is total number of users, then the second thresholding could be arranged to 10 or 20 etc.；If load total amount is RB utilization rate, then the second thresholding could be arranged to 50% or 60%.Wherein, the second time can be set to according to practical situation 10 minutes or 20 minutes, and this is not specifically limited by the embodiment of the present invention.

Further, in order to distinguish each logic district, and enable the user terminal proper communication in each logic district, the present embodiment provide method before the determine first logic district is merged into second logic district, also include be second logic district configuration cell parameter step.Wherein, cell parameter includes but not limited to the parameters such as cell ID, adjacent area parameter, channel parameter, transmitting power.Other logic district in network can both be different from due to the cell parameter of arbitrary first logic district, therefore, be that the cell parameter of the second logic district configuration can be the cell parameter of arbitrary first logic district in the first logic district determined.In addition, it can also be the static cell parameter that pre-sets of the second logic district, or it is the cell parameter dynamically arranged, by the cell parameter of the static cell parameter pre-set or dynamically setting, the second logic district is made a distinction with other logic district in network.Wherein, in the specific implementation, static cell parameter is the fixing cell parameter that base station is pre-configured with, and the cell parameter dynamically arranged is the cell parameter that base station is dynamically arranged according to the situation of network small area layout.

It should be noted that, when the first logic district determined does not have user terminal, the load total amount of the first logic district determined is zero, if now load total amount is still below the second thresholding, then directly performs to be merged into the first logic district determined the operation of the second logic district.When there is one or more user terminal the first logic district determined, then when load total amount is lower than the second thresholding, before the determine first logic district is merged into second logic district, the method that the embodiment of the present invention provides also includes the operation switched over by user terminal.Specifically include: send the first search instruction of the information carrying the second logic district to the user terminal in each first logic district, make the signal of communication according to information search second logic district of the second logic district carried in the first search instruction of the user terminal in each first logic district, and after the signal of communication searching the second logic district, be switched to the second logic district.Wherein, the information of the second logic district is user terminal for the second logic district of identifying in network thus information that the signal of communication of the second logic district is scanned for.The information of the second logic district can include the cell ID of the second logic district, the information such as frequency corresponding to the second logic district can also be included, the information of the second logic district that the embodiment of the present invention is carried in this is not to the first search instruction specifically limits, and the user terminal in each first logic district can pass through the signal of communication of information search second logic district of the second logic district carried in the first search instruction.

Owing to now also the first logic district determined not being merged into second logic district, network does not also have the second logic district, therefore, the user terminal in each first logic district can't search the signal of communication of the second logic district when just starting to search for.In the user terminal in each first logic district process according to the signal of communication of information search second logic district of the second logic district carried in the first search instruction, it is possible to perform to be merged into the first logic district determined the operation of one the second logic district.After having merged, the user terminal in each first logic district just may search for the signal of communication of the second logic district, and is switched to the second logic district after the signal of communication searching the second logic district.

In order to not affect the communications status of the user terminal in each first logic district, needing to be merged into the first logic district determined the time shared by one the second logic district controls within certain time, therefore, it is to be determined to the first logic district be merged into time shared by second logic district and hold time less than system switching.Wherein, system switches the time of the communications status being able to maintain that terminal being default of holding time, if the time of terminal searching signal of communication exceedes system switching and holds time, then the communications status of terminal is probably interrupted.It can be specifically that in system, switching maintains the time set by intervalometer T304 that system switching is held time, its size can be set to 500ms～2s according to practical situation, can also being other times size, the embodiment of the present invention specifically limits in this size system switching not held time.

In the specific implementation, the first logic district determined is merged into second logic district, refer to that base station is passed through to adjust internal parameter and arranged, it is to be determined to the first logic district as second logic district, and make the second logic district use the cell parameter configured.

For example, as shown in Fig. 3 (a), illustrate for the first logic district that step 201 is determined for the 1, first logic district, the first logic district 2 and the first logic district 3.Load total amount in the 1, first logic district, the first logic district 2 that step 202 gets and the first logic district 3 is lower than the second thresholding, and the persistent period is more than after the second time, send the first search instruction of the information carrying the second logic district to user terminal C and the D in the user terminal A in the first logic district 1 and B, the first logic district 2, user terminal E in the first logic district 3, and in user terminal A, B, C, D and E search procedure, the second logic district is merged in the 1, first logic district, the first logic district 2 and the first logic district 3.After merging completes, user terminal A in first logic district 1 and user terminal C and the D in B, the first logic district 2, user terminal E in the first logic district 3 search the signal of communication of the second logic district, and it is switched to the second logic district, obtain the schematic diagram as shown in Fig. 3 (b).

After user terminal in each first logic district is switched to the second logic district, the user terminal being switched to the second logic district all uses the cell parameter of the second logic district to communicate, and spendable carrier wave is the carrier wave corresponding to the second logic district, this carrier wave is same frequency with the carrier wave merged corresponding to front first logic district.

In addition, when uplink communication, channel quality according to the user terminal sending data, can select one to receive the best base station of signal for receiving the data that user terminal sends so that the signal of the data received strengthens from the multiple base stations in the second logic district；When downlink communication, each base station in the second logic district sends identical data to user terminal simultaneously so that the signal of the data that user terminal receives strengthens.Therefore, it is to be determined to the first logic district be merged into the second logic district after, improve the communication quality of network.

Cell combining networking can be realized by above-mentioned steps 201 to step 203, but due to the throughput degradation of system after merging, in order to take into account the handling capacity of system while improving the communication quality of network, when the load of the second logic district obtained after merging increases, the mode split can also be taked further, to improve the handling capacity of system, concrete fractionation mode sees below step.

204: obtain the load of the second logic district.

Wherein, the load of the second logic district can be the technical specifications such as the number of users of the second logic district, RB utilization rate, utilization rate of air interface resource, handling capacity, it is also possible to comprehensively determines according to above-mentioned multiple technical specifications.

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

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

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

For this step, if executive agent is base station, then the second logic district after the load of the second logic district reaches the first thresholding, directly can be split at least two the 3rd logic district by base station.If executive agent is external system devices, after then external system devices needs the load in the second logic district to reach the first thresholding, send the instruction performing to split to base station, base station according to the instruction performing fractionation received, the second logic district split at least two the 3rd logic district.

No matter executive agent is base station or external system devices, after the determine first logic district is merged into the second logic district, the throughput of system of the second logic district have dropped compared with the handling capacity before merging, therefore, when the load of the second logic district that step 204 gets reaches the first thresholding, needing to split the second logic district, the data communication to ensure system is unaffected.Additionally, again due to the load meeting real-time change of the second logic district, in order to avoid load significantly reduces again after certain time point reaches the first thresholding, the embodiment of the present invention is when splitting, load except considering the second logic district reaches the situation of the first thresholding, it is also contemplated that the load of the second logic district reaches the persistent period of the first thresholding.Accordingly, it would be desirable to the load in the second logic district reaches the first thresholding, and after the persistent period exceedes the very first time, just perform to split into the second logic district the operation of at least two the 3rd logic district.Wherein, the first thresholding can arrange different numerical value according to the type difference of the load of the second logic district.Such as, if the load of the second logic district is total number of users, then the first thresholding could be arranged to 50 or 100 etc.；If the load of the second logic district is RB utilization rate, then the first thresholding could be arranged to 80% or 90%.Wherein, the very first time can be set to according to practical situation 10 minutes or 20 minutes, and this is not specifically limited by the embodiment of the present invention.

Further, in order to distinguish each logic district, and enabling the user terminal proper communication in each logic district, the method that the present embodiment provides, before the second logic district splits at least two the 3rd logic district, also includes the step for each 3rd logic district configuration cell parameter.Wherein, cell parameter includes but not limited to: the parameters such as cell ID, adjacent area parameter, channel parameter, transmitting power.Each 3rd logic district can be the static cell parameter pre-set, or being the cell parameter dynamically arranged, each 3rd logic district is made a distinction by the cell parameter thereby through the static cell parameter pre-set or dynamically setting with other logic district in network.Additionally, owing to the cell parameter of the second logic district also is able to other logic district of being different from network, but the cell parameter only one of which of the second logic district, therefore can selecting the cell parameter that cell parameter is the second logic district of one of them the 3rd logic district, the cell parameter of other the 3rd logic district is the static cell parameter pre-set or the cell parameter dynamically arranged.In addition, can also adopt other modes is each 3rd logic district configuration cell parameter, the cell parameter of the 3rd logic district such as can be configured according to the cell parameter of the first logic district, and when the number of the 3rd logic district is less than or equal to the first logic district, it is also possible to arbitrarily select the cell parameter identical with the number of the 3rd logic district respectively as the cell parameter of each 3rd logic district from the cell parameter of the first logic district.When the number of the 3rd logic district is more than the first logic district, can cell parameter using the cell parameter of each first logic district as each 3rd logic district, and pre-set static cell parameter for other the 3rd logic district or cell parameter be dynamically set.For specifically adopting which kind of mode to be each 3rd logic district configuration cell parameter, the embodiment of the present invention does not specifically limit at this.

It should be noted that after the load in the second logic district reaches the first thresholding, before the second logic district splits at least two the 3rd logic district, the method that the embodiment of the present invention provides also includes the operation switched over by user terminal.Specifically include: send the second search instruction of the information carrying the 3rd logic district to the user terminal in the second logic district, make the signal of communication according to information search the 3rd logic district of the 3rd logic district carried in the second search instruction of the user terminal in the second logic district, and be switched to the 3rd logic district after the signal of communication searching the 3rd logic district.Wherein, the information of the 3rd logic district is user terminal for the 3rd logic district that identifies in network thus information that the signal of communication of the 3rd logic district is scanned for.The information of the 3rd logic district can include the cell ID of the 3rd logic district, the information such as frequency corresponding to the 3rd logic district can also be included, the information of the 3rd logic district that the embodiment of the present invention is carried in this is not to the second search instruction specifically limits, and the user terminal in the second logic district can pass through the signal of communication of information search the 3rd logic district of the 3rd logic district carried in the first search instruction.Can according to being about to split the coverage condition of the 3rd logic district obtained, the information of the 3rd logic district carried in the second search instruction that the user terminal in the second logic district sends is the information being about to cover the 3rd logic district of this user terminal.Therefore, the 3rd logic district that the user terminal in the second logic district is switched to is the 3rd logic district covering this user terminal.

Owing to the second logic district now also not splitting at least two the 3rd logic district, also not having the 3rd logic district in network, therefore, the user terminal in the second logic district can't search the signal of communication of the 3rd logic district when just starting to search for.In the process of the signal of communication of user terminal search the 3rd logic district in the second logic district, it is possible to perform to split into the second logic district the operation of at least two the 3rd logic district.After fractionation completes, the user terminal in the second logic district may search for the signal of communication of the 3rd logic district, and is switched to the 3rd logic district of correspondence after the signal of communication searching the 3rd logic district.

In order to not affect the communications status of the user terminal in the second logic district, the time split into shared by least two the 3rd logic district by the second logic district is needed to control within certain time, therefore, the time shared by least two the 3rd logic district that split into the second logic district holds time less than system switching.Wherein, system switching is held time and is referred to that in system, switching maintains the time set by intervalometer T304, its size can be set to 500ms～2s according to practical situation, it is also possible to for other times size, the embodiment of the present invention specifically limits in this size system switching not held time.

In the specific implementation, second logic district is split at least two the 3rd logic district, refer to that base station is passed through the parameter within adjustment and arranged, the second logic district is split as at least two the 3rd logic district, and makes each 3rd logic district use the cell parameter of configuration.

For example, as shown in Fig. 3 (c), still with in step 203 by the first logic district 1, it is that example illustrates that the second logic district is merged in first logic district 2 and the first logic district 3, load in the second logic district that step 204 gets reaches the first thresholding, and after the persistent period exceedes the very first time, user terminal A in the second logic district, B sends the second search instruction of the information carrying the 3rd logic district 1, to the user terminal C in the second logic district, D and E sends the second search instruction of the information carrying the 3rd logic district 2, and in user terminal A, B, C, second logic district is split as the 3rd logic district 1 and the 3rd logic district 2 by D and E search procedure.After fractionation completes, user terminal A in second logic district, B search the signal of communication of the 3rd logic district 1, and it being switched to the 3rd logic district 1, the user terminal C in the second logic district, D and E search the signal of communication of the 3rd logic district 2, and are switched to the 3rd logic district 2.

After user terminal in the second logic district is switched to the 3rd logic district, the user terminal being switched to the 3rd logic district all uses the cell parameter of the 3rd logic district to communicate, and spendable carrier wave is the carrier wave corresponding to the 3rd logic district, this carrier wave is same frequency with the carrier wave merged corresponding to front first logic district.

Additionally, due to after being split the second logic district, the sum increase of logic district in network, the user terminal being positioned at edge, logic district increases so that network integrated communication Quality Down.In order to improve the communication quality of network, after the second logic district is split as at least two the 3rd logic district, the communication quality of the user terminal at CoMP (CoordinatedMultiplePoints, multipoint cooperative) technology improvement the 3rd edge, logic district can also be adopted.

Specifically, when uplink communication, the base station of the 3rd logic district receives the data that the user terminal at the 3rd edge, logic district sends, the base station of other simultaneously adjacent with the 3rd logic district logic district also receives the data that the user terminal at the 3rd edge, logic district sends, and the data collaborative that the user terminal at the 3rd edge, logic district sends is sent to the base station of the 3rd logic district so that the signal of the data that the base station of the 3rd logic district receives strengthens；When downlink communication, while the base station of the 3rd logic district sends the data to the user terminal at the 3rd edge, logic district, it is also sent to the base station of other logic district adjacent with the 3rd logic district, the user terminal sending the data to the 3rd edge, logic district is worked in coordination with so that the user terminal at the 3rd edge, logic district receives the signal of data to be strengthened by the base station of other logic district.Therefore, although for the handling capacity considering system, need the second logic district is split as at least two the 3rd logic district when the load of the second logic district is bigger, the communication quality making network decreases, but by the 3rd logic district after fractionation uses CoMP technology, it is also possible to the communication quality of the network being lowered after being effectively improved fractionation.

In the specific implementation, it is possible to continuously carry out above-mentioned steps 201 to step 205 according to the situation of load in network, adjust the mode of cell networking in real time, while taking into account the handling capacity of system, optimize the communication quality of network.In addition, in the panel region that there is multiple logic district, according to above-mentioned steps 201 to step 205, multiple first logic district can be merged at least two the second logic district respectively, again each second logic district is split and become at least two the 3rd logic district, realize in a panel region, carry out the merging of logic district and the fractionation of logic district simultaneously, while taking into account throughput of system, the overall network communication quality improved in this panel region.Wherein, specifically which the first logic district is merged into second logic district, and after merging, the second logic district is split into several 3rd logic district, can determine according to the information being pre-configured with, it is also possible to dynamically determine according to practical situation.The carrier wave of the second logic district and the first corresponding same frequency in logic district being merged into the second logic district, carrier wave corresponding to the second different logic district can be same frequency, it can also be different frequency, further, the 3rd logic district with split before the carrier wave of the second corresponding same frequency in logic district.

In sum, the method that the embodiment of the present invention provides, after at least two first logic district of the carrier wave of corresponding same frequency is merged into second logic district, after the load of the second logic district got reaches the first thresholding, second logic district is split at least two the 3rd logic district, make by multiple first logic district after merging, second logic district is split time bigger by the load of the second logic district that can also obtain after merging, the communication quality of network and the handling capacity of system are taken into account, improve the communication capacity of network.And, can also continue to change the networking mode of community in communication process, namely be performed continuously over cell combining and community splits such that it is able to change the networking mode of community according to the change of system situation in real time, apply comparatively flexible.

Embodiment three

The handling capacity of communication quality and system in order to take into account network, a kind of method embodiments providing cell networking, the executive agent of the method can also be able to be other external system devices for base station.For the ease of explanation, the embodiment of the present invention is in conjunction with the content of above-described embodiment one, with community to be combined at least two the first logic district, user terminal is in the coverage of multiple logic district, and spendable carrier wave be the multiple carrier waves corresponding to multiple logic district that this user terminal is positioned at is example, the method that the present embodiment is provided is illustrated.Referring to Fig. 4, the method flow that the embodiment of the present invention provides includes:

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

Wherein, the corresponding carrier wave in each logic district in network, and carrier wave corresponding to multiple logic district can be same frequency.Therefore, when determining the first logic district, it is possible to determine at least two the first logic district according to the information being pre-configured with from multiple logic district of the carrier wave of corresponding same frequency.In addition to this it is possible to dynamically determine at least two the first logic district from multiple logic district of the carrier wave of corresponding same frequency according to practical situation.For example, it is possible to dynamically determine at least two the first logic district from multiple logic district of the carrier wave of corresponding same frequency according to technical specifications such as the number of users of each logic district, RB utilization rate, utilization rate of air interface resource, handling capacities in multiple logic district of the carrier wave of corresponding same frequency.For specifically selecting at least two first logic district of carrier wave which kind of mode determines corresponding same frequency and the quantity of the first logic district determined, the embodiment of the present invention does not all specifically limit at this.

402: obtain the load total amount of the first logic district determined.

It should be noted that when the first logic district determined does not have user terminal, it is determined that the load total amount of the first logic district be zero, if now load total amount is still below the second thresholding, is then performed without step 403, but continues executing with subsequent step 404.When having one or more user terminal in the first logic district determined, then after load total amount is lower than the second thresholding, the method that the embodiment of the present invention provides also includes the step 403 switched over by user terminal.

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

Wherein, owing to user terminal in embodiments of the present invention is within the coverage of multiple logic district, it is thus determined that the first logic district in user terminal except the coverage in the first logic district, also in the coverage of other logic district, other logic district covering the user terminal in the first logic district can be one or more, covering other logic district of user terminal in the first logic district of determining and the first logic district determined can the carrier wave of corresponding same frequency, it is also possible to the carrier wave of correspondence different frequency.Due to when two logic district are neighbor logic community, when the carrier wave of the two logic district correspondence same frequency, it is located in one of the user terminal at the edge of logic district it is also assumed that covered by another logic district, it is possible to be switched to another logic district.Therefore, when having at least one logic district in other logic district of the user terminal covered in the first logic district of determining with the carrier wave of the first corresponding same frequency in logic district determined, the user terminal at the edge of the first logic district that can will be located in determining is switched to other logic district of the carrier wave with the first corresponding same frequency in logic district determined, and other user terminals in the first logic district determined are switched to other logic district of carrier wave with the first corresponding different frequency in logic district determined.

For this step, if executive agent is base station, then user terminal after load total amount is lower than the second thresholding, directly can be switched to other logic district from the first logic district determined by base station.If executive agent is external system devices, then external system devices needs after load total amount is lower than the second thresholding, send the instruction performing switching to base station, base station according to the instruction performing switching received, user terminal is switched to other logic district from the first logic district determined.

No matter executive agent is base station or external system devices, owing to the user terminal in the first logic district of determining is in the coverage of multiple logic district.Therefore, the load total amount got in step 402 lower than the second thresholding after, first can not perform to be merged into the first logic district determined the step of one the second logic district, but first carry out the step that the user terminal of the first logic district determined is switched to other logic district, the user terminal making the first logic district determined can continue to keep communications status in other logic district, ensure that the determine first logic district is being merged in the process of second logic district and is not havinging the phenomenon that communications status interrupts by the user terminal of the first logic district determined.Wherein, if other logic district covering user terminal are multiple, then user terminal can switch over one other logic district of arbitrary selection.Additionally, due to load total amount meeting real-time change, in order to avoid load total amount enlarges markedly again after certain time point is lower than the second thresholding, except considering load overall control situation in the second thresholding, also contemplate the load total amount persistent period in the second thresholding, therefore, it can the load total amount in the first logic district determined lower than the second thresholding, and the persistent period is more than after the second time, just the user terminal of the first logic district that execution is determined is switched to the operation of other logic district.Wherein, the second thresholding can arrange different numerical value according to the type difference of load total amount.Such as, if load total amount is total number of users, then the second thresholding could be arranged to 10 or 20 etc.；If load total amount is RB utilization rate, then the second thresholding could be arranged to 50% or 60%.Wherein, the second time can be set to according to practical situation 10 minutes or 20 minutes, and this is not specifically limited by the embodiment of the present invention.

For example, as shown in Fig. 5 (a), the first logic district of the carrier wave of the corresponding same frequency determined for step 401 illustrates for the 1, first logic district, the first logic district 2 and the first logic district 3.Load total amount in the 1, first logic district, the first logic district 2 that step 402 gets and the first logic district 3 is lower than the second thresholding, and the persistent period is more than, after the second time, the user terminal A of the first logic district 1 being switched in covering user terminal A logic district 4；The user terminal B of the first logic district 1 is switched in covering user terminal B logic community 5；User terminal C and the D of the first logic district 2 is switched in covering user terminal C and D logic district 6；The user terminal E of the first logic district 3 is switched in covering user terminal E logic district 7, as shown in Fig. 5 (b).

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

Further, in order to distinguish each logic district, and enable the user terminal proper communication in each logic district, the present embodiment provide method before the determine first logic district is merged into second logic district, also include be second logic district configuration cell parameter step.Wherein, cell parameter includes but not limited to: the parameters such as cell ID, adjacent area parameter, channel parameter, transmitting power.Can both be different from other logic district in network due to the cell parameter of arbitrary first logic district, therefore, the cell parameter of the second logic district configuration can be the cell parameter of arbitrary first logic district in the first logic district determined.In addition, it can also be the static cell parameter pre-set, or it is the cell parameter dynamically arranged in the process performing the embodiment of the present invention, by the cell parameter of the static cell parameter pre-set or dynamically setting, the second logic district is made a distinction with other logic district in network.Wherein, static cell parameter is the fixing cell parameter that base station is pre-configured with, and the cell parameter dynamically arranged is the cell parameter that base station is dynamically arranged according to the situation of network small area layout in the specific implementation.

405: the user terminal being switched in other logic district is switched to the second logic district.

For this step, if the executive agent of step 404 is base station, then base station can directly perform to be switched to by the user terminal being switched in other logic district in this step the operation of the second logic district.If the executive agent of step 404 is external system devices, needing to send in external system devices and perform the instruction that merges to base station and after being undertaken by base station the first logic district determined is merged into second logic district, base station continues to perform, in this step, the user terminal being switched in other logic district is switched to the second logic district.

Specifically, it is possible to the load according to other logic district, all or part of user terminal being switched in other logic district is switched to the second logic district, thus reaching the purpose of balanced second logic district and the load of other logic district.Such as, if the load of other logic district exceedes certain threshold range, then the whole user terminals being switched in other logic district are switched to the second logic district, or the certain customers' terminal being switched in other logic district is switched to the second logic district so that the load of other logic district is maintained within this threshold range.

Additionally, except the user terminal being switched in other logic district is switched to the second logic district, it is also possible to user terminal that is original for other logic district or that be newly added is switched to the second logic district and is switched to the second logic district.

After the user terminal being switched in other logic district is switched to the second logic district, the user terminal being switched to the second logic district all uses the cell parameter of the second logic district to communicate, and spendable carrier wave is the carrier wave corresponding to the second logic district, this carrier wave is same frequency with the carrier wave merged corresponding to front first logic district.

For example, after the second logic district is merged in the 1, first logic district, the first logic district 2 and the first logic district 3 by step 404, the user terminal A being switched in logic district 4 is switched to the second logic district；The user terminal B being switched in logic district 5 is switched to the second logic district；User terminal C and the D being switched in logic district 6 is switched to the second logic district；The user terminal E being switched in logic district 7 is switched to the second logic district, obtains the schematic diagram as shown in Fig. 5 (c).

Additionally, after the user terminal being switched in other logic district is switched to the second logic district, user terminal is identical with the mode that above-described embodiment two provides with the mode of downlink communication at the uplink communication of the second logic district, repeats at this again.

Cell combining networking can be realized by above-mentioned steps 401 to step 405, but due to the throughput degradation of system after merging, in order to take into account the handling capacity of system while improving the communication quality of network, when the load of the second logic district obtained after merging increases, the mode split can also be taked further, to improve the handling capacity of system, concrete fractionation mode sees below step.

406: obtain the load of the second logic district.

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

Wherein, owing to user terminal in embodiments of the present invention is within the coverage of multiple logic district, therefore the user terminal in the second logic district is except the coverage in the second logic district, also in the coverage of other logic district, other logic district covering the user terminal in the second logic district can be one or more, cover the carrier wave of other logic district of user terminal in the second logic district and the second corresponding same frequency in logic district, it is also possible to the carrier wave of corresponding different frequency.Due to when two logic district are neighbor logic community, when the carrier wave of the two logic district correspondence same frequency, it is located in one of the user terminal at the edge of logic district it is also assumed that covered by another logic district, it is possible to be switched to another logic district.Therefore, when other logic district of the user terminal covered in the second logic district have the carrier wave of at least one logic district and the second corresponding same frequency in logic district, the user terminal at the edge of the second logic district can be will be located in and be switched to other logic district of the carrier wave with the second corresponding same frequency in logic district, and other user terminals in the second logic district are switched to other logic district of carrier wave with the second corresponding different frequency in logic district.

For this step, if executive agent is base station, then user terminal after the load of the second logic district reaches the first thresholding, directly can be switched to other logic district from the second logic district by base station.If executive agent is external system devices, after then external system devices needs the load in the second logic district to reach the first thresholding, send the instruction performing switching to base station, base station according to the instruction performing switching received, user terminal is switched to other logic district from the second logic district.

No matter executive agent is base station or external system devices, and owing to the user terminal in the second logic district is in the coverage of multiple logic district, then user terminal can use the multiple carrier waves corresponding to multiple logic district covering this user terminal.Therefore, step 406 obtain to the load of the second logic district reach the first thresholding time, can first not perform to split into the second logic district the step of at least two the 3rd logic district, and be carried out being switched to the user terminal in the second logic district from the second logic district the step of other logic district, so that the user terminal of the first logic district determined can continue to keep communications status in other logic district.Wherein, if other logic district covering user terminal are multiple, then user terminal can be switched to other logic district arbitrary.Additionally, again due to the load meeting real-time change of the second logic district, in order to avoid load significantly reduces again after certain time point is lower than certain threshold range, the embodiment of the present invention when being switched to other logic district covering user terminal by user terminal from the second logic district, load except considering the second logic district reaches the situation of the first threshold range, the load also contemplating the second logic district reaches the persistent period of the first thresholding, therefore, the load in the second logic district is needed to reach the first thresholding, and after the persistent period exceedes the very first time, just perform to be switched to the user terminal in the second logic district from the second logic district the operation of other logic district.Wherein, the first thresholding can arrange different numerical value according to the type difference of the load of the second logic district.Such as, if the load of the second logic district is total number of users, then the first thresholding could be arranged to 50 or 100 etc.；If the load of the second logic district is RB utilization rate, then the first thresholding could be arranged to 80% or 90%.Wherein, the very first time can be set to according to practical situation 10 minutes or 20 minutes, and this is not specifically limited by the embodiment of the present invention.

For example, the load getting the second logic district in step 406 reaches the first thresholding, and after the persistent period exceedes the very first time, owing to the load of logic district 4 is in certain threshold range, then the user terminal A of the second logic district is switched to the logic district 4 covering user terminal A；Similarly, the user terminal B of the second logic district is switched to the logic district 5 covering user terminal B；User terminal C and the D of the second logic district is switched to the logic district 6 covering user terminal C and D；The user terminal E of the second logic district is switched to the logic district 7 covering user terminal E, obtains the schematic diagram as shown in Fig. 5 (d).

In addition, after the user terminal in the second logic district is switched to other logic district from the second logic district, can directly perform to split into the second logic district the step 408 of at least two the 3rd logic district, it is also possible to determine whether the step performing that the second logic district is split at least two the 3rd logic district according to the load condition of other logic district.Specifically include: obtain the load of other logic district, after the load in other logic district each reaches the 3rd thresholding, perform to split into the second logic district the step 408 of at least two the 3rd logic district.

Wherein, other logic district can be one or more, when other logic district are multiple, it is necessary to obtain the load of other logic district each.The load of other logic district each can be the technical specifications such as the number of users of other logic district each, RB utilization rate, utilization rate of air interface resource, handling capacity, it is also possible to comprehensively determines according to above-mentioned multiple technical specifications.Before the second logic district splits at least two the 3rd logic district, the load except considering other logic district reaches the situation of the 3rd thresholding, it is also contemplated that the load of other logic district reaches the persistent period of the 3rd thresholding.Accordingly, it would be desirable to the load in the second logic district reaches the 3rd thresholding, and after the persistent period reached for the 3rd time, just perform to split into the second logic district the operation of at least two the 3rd logic district.Wherein, the 3rd thresholding can arrange different numerical value according to the type difference of the load of the second logic district.Such as, if the load of the second logic district is total number of users, then the 3rd thresholding could be arranged to 50 or 100 etc.；If the load of the second logic district is RB utilization rate, then the 3rd thresholding could be arranged to 80% or 90%.Wherein, the 3rd time can be set to according to practical situation 10 minutes or 20 minutes, and this is not specifically limited by the embodiment of the present invention.

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

For this step, if executive agent is base station, then the second logic district directly can be split at least two the 3rd logic district by base station, then external system devices needs to send the instruction performing to split to base station, base station according to the instruction performing fractionation received, the second logic district splits at least two the 3rd logic district.

If after in step 407 user terminal being switched to other logic district from the second logic district, judge the load condition of other logic district again, and the load in other logic district reach the 3rd thresholding after just perform to split into the second logic district the operation of at least two the 3rd logic district, then reach the process of the 3rd thresholding at the load that user terminal is switched to from the second logic district other logic district and other logic district, second logic district may newly increase user terminal, therefore after the load of other logic district reaches the 3rd thresholding, after also needing to first the user terminal newly increased in the second logic district to be switched to other logic district, the second logic district is split at least two the 3rd logic district again.By whole user terminals of the second logic district being all switched to other logic district before the second logic district is split at least two the 3rd logic district, the whole user terminals making the second logic district can keep communications status in other logic district, ensures that the user terminal of the second logic district splits in the second logic district and does not have the phenomenon that communications status interrupts in the process of at least two the 3rd logic district.

It should be noted that, second logic district is split at least two the 3rd logic district, refer to that base station is passed through the parameter within adjustment and arranged, the second logic district is split as at least two the 3rd logic district, and makes each 3rd logic district use the cell parameter of configuration.

409: the user terminal being switched in other logic district is switched to the 3rd logic district.

Specifically, it is possible to the user terminal being switched in other logic district is switched to the 3rd logic district that this user terminal self geographic area, place is corresponding.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 user terminal is switched to is identical with the first original logic district；If the coverage of the 3rd logic district after splitting is different from the coverage of the first original logic district, then user is still switched to the 3rd logic district that can cover this user terminal.

In this step, the user terminal being switched in other logic district is switched to the 3rd logic district and may include that the load according to other logic district, all or part of user terminal being switched in other logic district is switched to the 3rd logic district of correspondence.Such as, if the load of other logic district reaches certain threshold range, then the user terminal being switched in other logic district is all switched to the 3rd logic district of correspondence, or the certain customers' terminal being switched in other logic district is switched to the 3rd logic district of correspondence so that the load of other logic district is maintained within this threshold range.Further, it is also possible to user terminal that is original for other logic district or that be newly added is switched to the second logic district.

For example, after the second logic district is split as the 3rd logic district 1 and the 3rd logic district 2 by step 408, the user terminal A being switched in logic district 4 is switched to the 3rd logic district 1；The user terminal B being switched in logic district 5 is switched to the 3rd logic district 1；User terminal C and the D being switched in logic district 6 is switched to the 3rd logic district 2；The user terminal E being switched in logic district 7 is switched to the 3rd logic district 2, obtains the schematic diagram as shown in Fig. 5 (e).

In this step, if the executive agent of step 408 is base station, then base station can directly perform to be switched to by the user terminal being switched in other logic district in this step the operation of the 3rd logic district.If the executive agent of step 408 is external system devices, needing to send in external system devices and perform the order that splits to base station and after being undertaken by base station the second logic district is split at least two the 3rd logic district, base station continues to the operation performing that the user terminal being switched in other logic district is switched in this step the 3rd logic district.
