Referring to Fig. 3, Fig. 3 is a kind of flow diagram of cell switching method disclosed by the embodiments of the present invention.As shown in figure 3, this method may include following steps.

Step S301, user equipment A send measurement report to macro base station.

In one embodiment, the measuring control information for the carrying configuration parameter that user equipment A can be sent based on macro base station, it is determined whether send measurement report to macro base station.User equipment A can receive the signal quality of macro base station and micro-base station in macrocell, such as, in LTE system or lte-a system, the signal quality of macro base station and micro-base station that user equipment A is received can be Reference Signal Received Quality (Reference Signal Receiving Quality,) or Reference Signal Received Power (Reference Signal Receiving Power, RSRP) RSRQ.Also, entrained configuration parameter includes the amount of bias for above-mentioned signal quality, i.e. configuration parameter in the measuring control information that macro base station is sent.User equipment A is based on the signal quality received and is determined to send the trigger condition of measurement report for the amount of bias of the signal quality.For example, when user equipment A meets trigger condition, the measurement report of carrying event Ax can be sent to macro base station in LTE system or lte-a system, specific trigger condition is corresponding with time Ax, x=1,2,3,4 Deng (reference can be made to the specific event in 36.331 V10.1.0 standard of 3GPP TS describes).When meeting trigger condition described in event A3 based on the signal quality received and for the amount of bias of the signal quality is determining such as user equipment A, the measurement report of carrying event A3 can be sent to macro base station.When user equipment A sends measurement report, that is, show that user equipment A application carries out serving cell switching.In the embodiment of the present invention, user equipment A sends measurement report to macro base station, shows that user equipment A switches to Microcell to macro base station application serving cell from macrocell.

Step S302, the macro base station receives the measurement report that the user equipment A is sent, and switches to Microcell from macrocell based on the serving cell that the measurement report controls the user equipment A.

In one embodiment, after macro base station receives the measurement report that user equipment A is sent, then macro base station can send control command to user equipment A, switch to Microcell from macrocell to control user equipment A for its serving cell.Specifically, macro base station after the measurement report for receiving user equipment A transmission, can send switching request message, the relevant information prepared in the switching request message comprising switching to micro-base station.Micro-base station switches over preparation based on the switching request message received, and notice macro base station discharges resource when completing switching and preparing, and user equipment A is synchronized with micro-base station, to complete the serving cell handoff procedure of user equipment A.

Serving cell is switched to the Microcell from the macrocell under the control of the macro base station by step S303, the user equipment A.

Step S304, micro-base station obtain the information of the user equipment A.

In one embodiment, micro-base station can obtain the information of user equipment A.Specifically, micro-base station can receive the information that user equipment A is sent.Micro-base station can determine whether user equipment A is highspeed user's equipment by the information of acquisition user equipment A.Optionally, the information of user equipment A is carried in the test report that user equipment A is sent to micro-base station, i.e. for user equipment A when request switches serving cell, micro-base station can obtain the information of user equipment A.Alternatively, micro-base station by user equipment A send query messages, to obtain the information of user equipment A.Alternatively, micro-base station and user equipment A arrange acquisition time, micro-base station obtains the information of user equipment A in the acquisition time of agreement.

Step S305, the micro-base station is according to the information of the user equipment A, determine the user equipment for after highspeed user's equipment, the micro-base station sends first message to macro base station, highspeed user's equipment that the first message is used to that the macro base station to be requested to be changed in the macrocell that the macro base station is serviced sends the trigger condition of measurement report, and the Microcell is in the macro base station coverage area.

In one embodiment, when micro-base station is according to the information of the user equipment A of acquisition, determine that user sets Standby A is after highspeed user's equipment, micro-base station sends first message to macro base station, the first message is used to request the user equipment in macro base station change macrocell that can send the trigger condition of measurement report, and then increases the difficulty that macrocell high speed user equipment is switched into the Microcell.It should be noted that, herein, micro-base station determines whether user equipment is that the criterion of highspeed user's equipment is identical with macro base station, i.e. when the movement speed of user equipment or average movement speed reach micro-base station and the known default High Speed Threshold of macro base station, or, when the corresponding class letter of the movement speed of user equipment is micro-base station and macro base station known high speed grade, then micro-base station or macro base station can determine that the user equipment is highspeed user's equipment.Optionally, application scenarios as shown in Figure 1, when in macrocell there are when multiple Microcells, different Microcells for user equipment whether be highspeed user's equipment criterion it is different, i.e., different micro-base stations can arrange different default High Speed Thresholds or high speed grade from macro base station.In turn, when micro-base station sends first message to macro base station, when requesting highspeed user's equipment in macro base station change macrocell to send the trigger condition of measurement report, highspeed user's equipment referred herein is the micro-base station and highspeed user's equipment that the macro base station is determined according to known determining criterion.Certainly, the first message that macro base station can be sent based on different micro-base stations, determines highspeed user's equipment corresponding with the micro-base station.

Optionally, the quantity for highspeed user's equipment that micro-base station counts can be carried in above-mentioned first message.Optionally, micro-base station determines user equipment A as that can send first message to macro base station after highspeed user's equipment；Alternatively, micro-base station is over time when preset quantity threshold value (quantity of the highspeed user's equipment such as counted be more than), or sends first message to macro base station based on the sending cycle negotiated with macro base station, here, the embodiment of the present invention is without limitation.

Step S306, the macro base station receive the first message that the micro-base station is sent.

In one embodiment, macro base station receives the first message that micro-base station is sent.Wherein, macro base station can receive the first message of micro-base station within the time point of negotiation or the period of negotiation or macro base station can also receive the first message that micro-base station is sent at any time.

Step S307, after the macro base station determines the highspeed user equipment B in the macrocell, the macro base station changes the trigger condition that highspeed user's equipment B sends measurement report.

In one embodiment, after macro base station receives the first message of micro-base station transmission, it may be determined that highspeed user's equipment in macrocell, in the embodiment of the present invention, by taking macro base station determines that user equipment B is highspeed user's equipment as an example.Wherein, determine that the criterion of highspeed user's equipment is identical with the micro-base station due to macro base station, macro base station determines that user equipment B is that the mode of highspeed user's equipment can be found in the mode that micro-base station determines highspeed user's equipment.It should be noted that highspeed user's equipment B that macro base station determines here is for above-mentioned micro-base station, if other micro-base stations, due to determining the difference of criterion, it is possible to which macro base station determines that user sets Standby B is not highspeed user's equipment.For example, it is not highspeed user's equipment for micro-base station B that user equipment B, which is possible to for micro-base station A be highspeed user's equipment, in application scenarios as shown in Figure 1.

After macro base station determines highspeed user equipment B, the trigger condition that highspeed user's equipment B sends measurement report can be changed.Make highspeed user's equipment B after changing trigger condition, avoids sending measurement report to macrocell as far as possible.And then increase the difficulty of the switching cell highspeed user equipment B.To fundamentally prevent to be switched into the possibility of the Microcell for highspeed user's equipment relative to Microcell.

Step S308, when highspeed user's equipment B detects the Microcell, it is determined whether meet the trigger condition that measurement report is sent to the macro base station.

In one embodiment, when highspeed user's equipment B receives the signal quality of micro-base station, the trigger condition that can be changed by macro base station, determine whether the signal quality for the micro-base station being currently received can satisfy above-mentioned trigger condition, if can satisfy, then measurement report can be sent to macro base station, if it is impossible to meet can not send measurement report to macro base station.Specifically, highspeed user's equipment B will not send measurement report to macro base station, and then macro base station avoids highspeed user's equipment B and be switched into Microcell by the trigger condition of change highspeed user's equipment B if highspeed user's equipment B is unsatisfactory for the trigger condition；If highspeed user's equipment B meets trigger condition, highspeed user's equipment B sends measurement report to macro base station, then is recycled and executes step S301~step S308, and macro base station is made to further increase the difficulty that other highspeed user's equipment in macrocell are switched into Microcell.

It can be seen that, when micro-base station determines that there are when highspeed user's equipment in Microcell, first message can be sent to macro base station, macro base station is after receiving the first message, the trigger condition that highspeed user's equipment in macrocell sends measurement report can be changed, and then increase the difficulty that highspeed user's equipment is switched into Microcell, to can fundamentally prevent the possibility that highspeed user's equipment is switched into Microcell through the above way, the cell switching frequency for reducing highspeed user's equipment thereby reduces the dropped communication rate of highspeed user's equipment.

Referring to Fig. 4, Fig. 4 is the flow diagram of another cell switching method disclosed by the embodiments of the present invention.As shown in figure 4, this method is applied to micro-base station, and this method emphasis describes micro-base station and determines that user equipment is the concrete mode of highspeed user's equipment.This method may include following steps.

Step S401, micro-base station receive the measurement report that user equipment is sent.

In one embodiment, the measurement report that micro-base station can be sent by receiving user equipment, obtains the information of user equipment.When micro-base station receives the measurement report of user equipment transmission, show that user device applies switch out the corresponding Microcell of the micro-base station.At this point, whether micro-base station can be that highspeed user's equipment carries out comprehensive descision to the user equipment.To which micro-base station can be determined whether highspeed user's equipment by Microcell.In general, Residence time by highspeed user's equipment of Microcell in Microcell is shorter, does not need the switching for carrying out serving cell, will lead to the increase of dropped communication rate.Therefore, micro-base station needs to request that more highspeed user's equipment is avoided to be switched into Microcell to macro base station.

Step S402, the micro-base station determine that the user equipment is highspeed user's equipment.

In one embodiment, after micro-base station receives the measurement report of user equipment transmission, further it can determine whether the user equipment is highspeed user's equipment according to the information for carrying user equipment in measurement report.Wherein, micro-base station determines that user equipment whether be the concrete mode of highspeed user's equipment may include any one in following manner.

It (1), may include the velocity information of user equipment in the measurement report that micro-base station receives, the velocity information is the movement speed numerical value or class letter corresponding with the movement speed of the user equipment.

Specifically, micro-base station can parse the velocity information of the user equipment in measurement report according to the resolution rules negotiated in advance with user equipment, the velocity information can be the movement speed numerical value or class letter corresponding with movement speed of user equipment to report, which is high speed, middling speed or low speed etc. for the movement speed of identity user equipment.Micro-base station can send control signaling when detecting that the user equipment is switched into cell to user equipment, which carries velocity information when sending measurement report for controlling user equipment；Alternatively, the measurement report for carrying the velocity information of user equipment has been micro-base station with well known to user equipment, i.e., the user equipment in each Microcell is required to carry the velocity information of the user equipment when sending measurement report.

User equipment can be by the movement speed of the device monitorings such as sensor for the configuring user equipment, and can handle the movement speed of monitoring, such as determines the average movement speed of user equipment, or determine speed class mark etc. based on the movement speed of user equipment.User equipment can negotiate the threshold value that movement speed meets high-speed condition with micro-base station, i.e., default High Speed Threshold.The default High Speed Threshold or speed class mark can be determined based on parameters such as the range size of Microcell, the locomotivity of user equipment or mobile conditions.User equipment can determine that speed class is identified based on the average movement speed in Microcell, when determining that the average movement speed in Microcell is greater than 50KM/H such as user equipment, determine that class letter identifies for high speed；User equipment is determined in the average movement speed in Microcell between 50KM/H~30KM/H, determines class letter for middling speed mark；User equipment determines that the average movement speed in Microcell is less than 30KM/H, determines class letter for low speed mark.

After micro-base station receives the measurement report for carrying velocity information, if entrained velocity information is mobile speed The numerical value of degree, then can determine whether the movement speed numerical value is higher than default High Speed Threshold；If entrained velocity information is class letter, micro-base station determines whether the class letter is used for the movement speed of identity user equipment as high speed.If it is high speed that micro-base station, which determines that movement speed numerical value is higher than default High Speed Threshold or class letter for the movement speed of identity user equipment, micro-base station determines that the user equipment is highspeed user's equipment.

(2), the micro-base station obtains user equipment in the residence time of Microcell；

If the micro-base station determines that the average speed reaches the default High Speed Threshold, it is determined that the user equipment is highspeed user's equipment.

Specifically, micro-base station can further obtain user equipment in the residence time of Microcell after micro-base station receives the measurement report of user equipment to report.Wherein, residence time of the user equipment in Microcell can be obtained from the user equipment history presence information interacted with user equipment, such as in LTE or lte-a system, user equipment can be to the history presence information of base station report of user equipment, wherein, residence time can obtain in persistent district time (Time UE stayed in Cell) field of history presence information；Alternatively, micro-base station record user equipment is switched into the time point of Microcell, and the time point that micro-base station receives the measurement report of user equipment to report is recorded, user equipment is calculated in the residence time of Microcell according to the difference at above-mentioned two time point；Or, user equipment can be carried in the measurement report of user equipment to report in the residence time information of Microcell, as user equipment since enter Microcell in start timing up to user equipment transmission measurement report time, using the above-mentioned period as residence time information, micro-base station is sent to by measurement report.Optionally, micro-base station can also be in the information of other times of the user equipment in Microcell acquisition user equipment, such as mobile duration information and corresponding moving distance information.Micro-base station can monitor the motion track of the user equipment when user equipment is switched into Microcell, and the moving distance of user equipment is determined by motion track；Or it can also be by the motion track information of user equipment to report user equipment, the motion track information is for recording motion track etc. of the user equipment in Microcell, micro-base station can determine moving distance of the user equipment in Microcell based on the motion track information, micro-base station can calculate user equipment in the average speed of Microcell according to the motion track information and residence time.If micro-base station determines that average speed reaches default High Speed Threshold, micro-base station can determine that the user equipment is highspeed user's equipment.Wherein, default High Speed Threshold can be determined based on parameters such as Microcell size, the locomotivity of user equipment or mobile conditions.

Step S403, the micro-base station determine the user equipment for after highspeed user's equipment, the micro-base station sends first message to the macro base station, and the first message is for requesting the macro base station change macrocell Interior highspeed user's equipment sends the trigger condition of measurement report.

In one embodiment, after micro-base station determines that user equipment is highspeed user's equipment, micro-base station can send first message to macro base station, the first message is used to that highspeed user's equipment in macro base station change macrocell to be requested to send the trigger condition of measurement report, and then increases the difficulty of above-mentioned highspeed user's equipment switching cell.Wherein, the specific implementation for the trigger condition that macro base station change highspeed user's equipment sends measurement report can be found in the specific descriptions in embodiment illustrated in fig. 6, wouldn't repeat herein.

Optionally, micro-base station and the negotiable sending cycle for sending change request of macro base station, micro-base station send change request to macro base station when sending cycle is expired；Alternatively, micro-base station judges user equipment to send change request to macro base station immediately after highspeed user's equipment；Alternatively, then micro-base station sends change request to macro base station when micro-base station detects to reach preset quantity threshold value by the quantity of highspeed user's equipment of Microcell.

In the embodiment of the present invention, micro-base station can be determined in several ways by whether the user equipment of Microcell is highspeed user's equipment, when determining after the user equipment of Microcell is highspeed user's equipment, can request to increase the difficulty that highspeed user's equipment in macrocell is switched into the Microcell to macro base station.By the above-mentioned means, can accurately judge whether by the user equipment of Microcell be highspeed user's equipment, so as to further decrease the switching frequency of highspeed user's equipment when by Microcell, ensure that the communication quality of highspeed user's equipment.

Referring to Fig. 5, Fig. 5 is the flow diagram of another cell switching method disclosed by the embodiments of the present invention.As shown in figure 5, this method may include following steps.

Step S501, the micro-base station send control information to user equipment, and the control information carries default High Speed Threshold.

In one embodiment, micro-base station can send control information to the user equipment, wherein the control information carries default High Speed Threshold.In turn, user equipment can voluntarily judge whether the movement speed of user equipment is more than default High Speed Threshold.

Step S502 judges whether the movement speed of user equipment reaches the default High Speed Threshold after the user equipment receives the control information.

In one embodiment, after user equipment receives above-mentioned control information, it can determine whether the movement speed of the user equipment reaches default High Speed Threshold.Specifically, user equipment can determine the average movement speed of the user equipment in certain time, as user equipment will switch out Microcell, or user equipment to micro-base station send measurement report when, user equipment is determined from the average movement speed for being switched into Microcell to user equipment and switching out the user equipment in the time of Microcell, and judge whether the average movement speed reaches default High Speed Threshold, if judging, average movement speed reaches default High Speed Threshold, confirmation message then is sent to micro-base station, it should Confirmation message is for confirming that the movement speed of user equipment reaches default High Speed Threshold；Alternatively, user equipment real-time monitoring movement speed, when monitoring that movement speed reaches default High Speed Threshold, confirmation message can be sent to micro-base station, alternatively, sending confirmation message to micro-base station when the number that user equipment monitors to movement speed reach preset threshold is more than preset times.

Step S503, if the user equipment judges that the movement speed reaches default High Speed Threshold, Xiang Suoshu micro-base station sends confirmation message, and the confirmation message is for confirming that the movement speed of user equipment reaches default High Speed Threshold.

Step S504, if the information for the user equipment that the micro-base station obtains is confirmation message, the micro-base station determines that the user equipment is highspeed user's equipment, and the micro-base station sends first message to macro base station, and the first message is used to request the trigger condition of highspeed user's equipment transmission measurement report in the macro base station change macrocell.

In one embodiment, if the information for the user equipment that micro-base station obtains is confirmation message, micro-base station determines that the user equipment is highspeed user's equipment.Optionally, micro-base station can obtain the confirmation message by the measurement report that user equipment is sent, i.e., carry confirmation message in the measurement report that user equipment is sent.Further, micro-base station sends first message to macro base station, which is used to request highspeed user's equipment in change macrocell to send the trigger condition of measurement report, and then increases the difficulty that highspeed user's equipment is switched into Microcell.Wherein, the specific implementation for the trigger condition that highspeed user's equipment in macro base station change macrocell sends measurement report can be found in the specific descriptions in embodiment illustrated in fig. 6, wouldn't repeat herein.

In the embodiment of the present invention, micro-base station can quickly be confirmed with the presence or absence of highspeed user's equipment in Microcell, and then macro base station can be requested to change the trigger condition that user equipment is switched into Microcell in time by sending control information to user equipment.The cell switching frequency that highspeed user's equipment when by Microcell can be further decreased, ensure that the communication quality of highspeed user's equipment.

Referring to Fig. 6, Fig. 6 is the flow diagram of another cell switching method disclosed by the embodiments of the present invention.As shown in fig. 6, this method is applied to macro base station.This method may include following steps.

Step S601, macro base station receive the first message that micro-base station is sent, and highspeed user's equipment that the first message is used to that the macro base station to be requested to be changed in the macrocell that the macro base station is serviced sends the trigger condition of measurement report.

In one embodiment, macro base station receives the first message that micro-base station is sent, which is used to request the trigger condition of highspeed user's equipment transmission measurement report in the macro base station change macrocell.Specifically, after macro base station receives the first message of micro-base station transmission, know in Microcell there are highspeed user's equipment or There is highspeed user's equipment by Microcell, then macro base station needs to increase the difficulty that highspeed user's equipment in macrocell is switched into Microcell.Optionally, macro base station can send the trigger condition of measurement report by the configuration parameter in change measuring control information, highspeed user's equipment to change in above-mentioned macrocell.Such as in LTE or lte-a system, configuration parameter (i.e. amount of bias) in the measuring control information that user equipment is sent based on macro base station and the base station signal quality received, to determine whether the trigger condition for meeting reporting measurement reports, wherein, different event Ax correspond to different trigger conditions, by taking event A3 as an example, if user equipment determination meets the corresponding trigger condition of A3, pass through measurement report reported event A3.

Step S602 changes the configuration parameter in the measuring control information after the macro base station determines highspeed user's equipment in the macrocell.

In one embodiment, after macro base station determines highspeed user's equipment in macrocell, macro base station is requested based on the change, changes the configuration parameter in measuring control information.Wherein, the configuration parameter may include amplitude lag parameter and/or time lag parameter.Optionally, macro base station determines that highspeed user's equipment in macrocell can be found in the mode for highspeed user's equipment that micro-base station determines in Microcell.Here, micro-base station determines that the criterion of highspeed user's equipment is identical with macro base station, that is to say, that micro-base station and macro base station can determine the standard for presetting High Speed Threshold or high speed grade jointly.

Specifically, by taking the trigger condition of event A3 in LTE system as an example, as shown in Figure 7, curve 1 indicates signal strength (the measurement result of the neighbouring cell for the adjacent cell that user equipment measures, Mn) curve, the embodiment of the present invention are the signal strength of Microcell；Curve 2 indicates the curve after the signal strength additional amplitude lag parameter of adjacent cell, wherein, amplitude lag parameter for Mn may include Ofn (frequency specific offset of the frequency of the neighbor cell, the specific frequency of adjacent cell frequency biases), Ocn (cell specific offset of the neighbor cell, the specific cell of adjacent cell biases), Hys (hysteresis parameter for this event, the lag parameter of the event), curve 2 may particularly denote as Mn+Ofn+Ocn-Hy S；Curve 3 indicates signal strength (mesurement result of the service cell, the Ms) curve for the serving cell that user equipment measures, and the embodiment of the present invention is the signal strength of macrocell；Curve 3 indicates the curve after the signal strength additional amplitude lag parameter of serving cell, wherein, amplitude lag parameter for Ms may include Ofs (frequency specific offset of the service frequency, the specific frequency of serving cell frequency biases), Ocs (cell specific offset of the service cell, the specific cell of serving cell biases), Off (offset parameter for this event, the compensating parameter of the event), curve 4 may particularly denote as Ms+Ofs+Ocs+off.Wherein, the trigger condition of event A3 is Mn+Ofn+Ocn-Hys > Ms+Ofs+Ocs+off.Specifically, at the t1 moment, User equipment measures Mn+Ofn+Ocn-Hys=Ms+Ofs+Ocs+off, when by after TTT (time to trigger, time lag parameter) duration, i.e., at the t2 moment, user equipment sends measurement report to macro base station.

Macro base station changes configuration parameter, can specifically change above-mentioned amplitude lag parameter and/or time lag parameter.Such as, when macro base station changes amplitude lag parameter, macro base station can change Ocs parameter, can also change Ocn parameter.As shown in figure 8, curve 2 and curve 3 represent macro base station and do not change before configuration parameter, macrocell and Microcell signal strength that user equipment measures add the curve for the configuration parameter that do not change；After macro base station reduces Ocn parameter and increases Ocs parameter, it is curve 5 that the macro-cell signals intensity that user equipment measures, which adds the configuration parameter curve after change, and it is curve 6 that the Microcell signal strength that user equipment measures, which adds the configuration parameter curve after change,.Before macro base station does not change configuration parameter, user equipment meets trigger condition at the t1 moment, and after TTT1 duration, i.e., sends measurement report to macro base station at the t3 moment.And after macro base station changes configuration parameter, highspeed user's equipment needs just to be able to satisfy trigger condition at the t2 moment, therefore increases the sluggishness for meeting trigger condition to highspeed user's equipment, and highspeed user's equipment is avoided to be switched into Microcell.Or, it can also be by way of increasing time lag parameter, increase the sluggishness for meeting trigger condition to highspeed user's equipment, after changing configuration parameter such as macro base station, when at the t3 moment, determination meets trigger condition for it, it needs after TTT1 duration, measurement report is sent to macro base station at the t4 moment, after if the duration of TTT is increased to TTT2 from TTT1 by macro base station, user equipment will can send measurement report at the t5 moment, to further increase the difficulty that highspeed user's equipment in macrocell sends measurement report.After changing configuration parameter due to macro base station, the lag time that highspeed user's equipment in macrocell sends measurement report is increased, within this time, above-mentioned highspeed user's equipment is possible to have already been through Microcell, to avoid user equipment and switch to serving cell in Microcell.

Optionally, macro base station can determine the change amount of configuration parameter based on the quantity for highspeed user's equipment into Microcell that micro-base station notifies.Wherein, micro-base station can carry the quantity information of determining highspeed user's equipment in the change request for being sent to macro base station, the quantity for the highspeed user's equipment such as judged when micro-base station reaches preset quantity threshold value, trigger to macro base station send first message when, micro-base station can carry the quantity information of highspeed user's equipment in first message；For another example when micro-base station, which is based on predetermined period, sends change request to macro base station, micro-base station can also carry the quantity information of highspeed user's equipment in first message.Macro base station can determine the basic change amount of configuration parameter, and the basic change amount such as determined is k, wherein can be directed to different configuration parameters, determine different basic change amount k；Then macro base station can determine the change amount of configuration parameter according to the quantity information and basis change amount k of the highspeed user's equipment received, after the change amount for determining configuration parameter, then can determine Curve 5 as shown in Figure 8 or curve 6 distinguish the position of distance Curve 2 or curve 3.

Optionally, macro base station can also be determined the change amount of configuration parameter based on the high speed grade for highspeed user's equipment that micro-base station reports.Wherein, when micro-base station judge in Microcell there are user equipment be highspeed user's equipment after, it can also further determine that the high speed grade of highspeed user's equipment, such as micro-base station can determine that the high speed grade of highspeed user's equipment is level-one, second level according to the movement speed of highspeed user's equipment or the speed class information reported, wherein, series is bigger, then shows that the movement speed of highspeed user's equipment is faster.Every level-one high speed grade can correspond to a movement speed range of highspeed user's equipment.The high speed grade of highspeed user's equipment of its determination can be carried in the first request that micro-base station is sent, thus, macro base station can determine change amount for the high speed grade, such as change amount can be with high speed grade positive correlation.

Optionally, macro base station may also be combined with above two mode, i.e., the high speed class information of the highspeed user's number of devices information and highspeed user's equipment that carry in the change request that macro base station is sent based on micro-base station determines the change amount to configuration parameter.

Optionally, after macro base station also can receive the first message sent to a micro-base station, configuration parameter is once changed；After receiving the change request of micro-base station transmission next time, it can continue to be modified configuration parameter, wherein, this can be identical as the change amount of last time configuration parameter to the change amount of configuration parameter, it can also be different, until no longer receiving the first message of micro-base station transmission, show thoroughly to have prevented the phenomenon that highspeed user's equipment in macrocell is switched into Microcell.

The measuring control information of configuration parameter after carrying the change is sent to highspeed user's equipment in macrocell by step S603, the macro base station.

In one embodiment, the measuring control information for carrying the configuration parameter after changing can be sent to highspeed user's equipment in macrocell by macro base station, and highspeed user's equipment in macrocell is made to be determined to the trigger condition of reporting measurement reports based on the configuration parameter after change.

Optionally, the measuring control information can be also sent to all user equipmenies in macrocell by macro base station.

In the embodiment of the present invention, macro base station passes through after receiving the change request of micro-base station transmission, change the configuration parameter for sending the trigger condition of measurement report for influencing highspeed user's equipment, the difficulty that highspeed user's equipment is switched into Microcell can be increased, and then the cell switching frequency of highspeed user's equipment when by Microcell is reduced, it ensure that the communication quality of highspeed user's equipment.
