Step 210: if it is determined that the handling capacity of macrocell is more than or equal to default first thresholding or the congestion time of macrocell is big In being equal to default second thresholding, then macrocell initiates the place information inquiry for all user equipment (UE)s in macrocell.

Wherein, macrocell initiates the place information inquiry for all UE in macrocell, comprising:

Firstly, macrocell passes through the corresponding arrival bearing of each UE (Angle of in smart antenna receiver macrocell Arrival, AOA).For example, SmallCell is located at the 12 o'clock direction of base station.

Secondly, macrocell all UE into macrocell initiate random access requests and be calculated each UE it is corresponding when Between lead (Timing Advance, TA), and the distance between each UE and base station are determined based on the TA of each UE.

Finally, macrocell determines macrocell based on the corresponding AOA of each UE and the distance between each UE and base station In all UE location information.

Step 220: the query result of location information of the macrocell based on UE all in macrocell owns in conjunction in macrocell The location information and status information of SmallCell determines the SmallCell for needing to activate.

Specifically, the query result of location information of the macrocell based on UE all in macrocell, covers model in conjunction with macrocell Enclose the location information and status information of interior all SmallCell, however, it is determined that of the UE on the position of unactivated SmallCell Number is more than default third thresholding, it is determined that activates unactivated SmallCell.

For example, as shown in fig.3, macrocell obtains in coverage area from operation and maintenance center to be owned in the stage of pre-configuration The identification information of SmallCell, location information, status information, wherein SmallCell#0, SmallCell#1, SmallCell# 2, SmallCell#3 is unactivated SmallCell.First is preset when macrocell determines that the handling capacity of itself is more than or equal to Limit, place information inquiry of the triggering for all UE in macrocell.Location information of the macrocell based on UE all in this cell Query result, in conjunction with the location information and status information of SmallCell all in macrocell, wherein include in SmallCell#0 1 user includes 1 user in SmallCell#1, includes 3 users in SmallCell#2, includes 2 in SmallCell#3 A user determines the number of the UE on the position of unactivated SmallCell#2 at most and is more than preset third thresholding, then really Surely SmallCell#2 is activated.

Therefore, it when macrocell network is busy, is in congestion state, can trigger for UE location information in macrocell Inquiry, and the place information inquiry result based on UE and the SmallCell information for being pre-configured the stage determine what needs activated SmallCell can be realized and shunt in time to the data of macrocell, play the role of sharing macrocell load.Herein Data distribution can be switching or carrying separation, wherein switching refers to after SmallCell activation, by the data surface of UE and Control plane is all transferred in SmallCell；And carry separation and refer to after SmallCell activation, the control plane of UE is carried It is retained in macrocell, and all or part of data surface business is transferred in SmallCell.

It needs to be noted that if macrocell determines have at least two positions for determining unactivated SmallCell at this time The number of UE be more than default third thresholding, it is determined that activation meets the SmallCell of condition.

Further, if macrocell determines macrocell and determines that the SmallCell of activation belongs to the same base station, directly Sending and receiving play SmallCell activation；

Alternatively,

If macrocell determines macrocell and determines that the SmallCell of activation belongs to different base stations, to Operation and Maintenance Center sends SmallCell activation request, initiates SmallCell activation by operation and maintenance center.

In addition, being specifically divided into three kinds of situations to the deactivation of SmallCell in idle:

First, if macrocell receive belong to macro base station management and can send system information SmallCell send UE number is lower than default 4th thresholding or is more than the system message for presetting the 5th thresholding without service time, then to operation and maintenance center The closing instruction of the SmallCell is sent, and the core net SmallCell is notified to be turned off.

Second, if being not belonging to macro base station management and the SmallCell of system message capable of being sent determine the UE number of itself It is more than default 5th thresholding lower than default 4th thresholding or without service time, then sends the SmallCell to operation and maintenance center Closing instruction, and by the SmallCell own base station notice core net SmallCell be turned off.

Third, if macrocell, which detects, cannot send in the SmallCell of system message UE number lower than 4th default Limit is more than default 5th thresholding without service time, then the closing instruction of the SmallCell is sent to operation and maintenance center, and lead to Know that the core net SmallCell is turned off.

As shown in fig.4, in the embodiment of the present invention, to positioned at macrocell edge or the SmallCell adjacent with macrocell The detailed process being managed are as follows:

In the stage of pre-configuration, macrocell is obtained from operation and maintenance center is located at all of macrocell edge and neighboring community The identification information of SmallCell, location information, status information.

Step 400: Reference Signal Received Power and reference signal of the macrocell timing according to different community for UE receive Ratio Reference Signal Received Power (Reference Signal Receiving Power, RSRP)/reference signal of quality connects The measurement result for receiving quality (Reference Signal Receiving Quality, RSRQ) determines that leaving macrocell covers The number of the UE of lid.

Specifically, the method for the UE of macrocell covering is being left in macrocell judgement are as follows:

If macrocell receives the A2 event reported for UE, but does not receive needle when reaching preset time threshold The A3 event that UE is reported, it is determined that UE is leaving the coverage area of macrocell.

Wherein, the measurement result that A2 event is the RSRP/RSRQ that serving cell is directed to UE is lower than default 7th thresholding, A3 thing Part is the survey that other co-frequency cells are higher than that serving cell is directed to the RSRP/RSRQ of UE for the measurement result of the RSRP/RSRQ of UE Measure default 8th thresholding of result.

Step 410: if it is determined that the number for leaving the UE of macrocell covering is more than or equal to default 6th thresholding, then it is macro small Initiate the place information inquiry for the UE positioned at macrocell edge in area.

At this point, it is emphasized that the place information inquiry of the UE at triggering macrocell progress macrocell edge is to report A2 Event and UE number of A3 event is not reported to reach preset low thresholding.Therefore, it reports A2 but does not report the UE of A3 event The covering for leaving macrocell reports the UE of A3 event then to indicate in macrocell and the boundary with macrocell neighboring community Place.

Wherein, macrocell initiates the place information inquiry for the UE positioned at macrocell edge, comprising:

Firstly, macrocell is located at the corresponding AOA of each UE at macrocell edge by smart antenna receiver；

Secondly, macrocell initiates random access request to the UE for being located at macrocell edge and each UE correspondence is calculated TA, and the distance between each UE and base station are determined based on the TA of each UE.

Finally, macrocell is determined based on the corresponding AOA of each UE and the distance between each UE and base station positioned at macro The location information of the UE of cell edge.

Step 420: the query result of location information of the macrocell based on the UE for being located at macrocell edge is macro small in conjunction with being located at The location information and status information of area edge and all SmallCell of neighboring community determine the SmallCell for needing to activate.

Specifically, the query result of location information of the macrocell based on the UE for being located at macrocell edge, macro small in conjunction with being located at The location information and status information of area edge and all SmallCell of neighboring community, however, it is determined that a unactivated SmallCell Position on the number of UE be more than default 9th thresholding, it is determined that one SmallCell of activation.

For example, as shown in fig.5, macrocell is obtained from operation and maintenance center is located at macrocell edge in the stage of pre-configuration Identification information, location information, status information with all SmallCell of neighboring community.Wherein, SmallCell#0, SmallCell#1 is unactivated SmallCell.

Here the UE in SmallCell#1 reports A2 event but does not report A3 when reaching preset time threshold Event shows that the UE is leaving macrocell covering, and the UE in SmallCell#1 has reported A3 event, the i.e. measurement of cell A As a result it is better than the measurement result of macrocell, judges that the UE is in the intersection of macrocell and cell A, as shown in Figure 5.

Macrocell is determined according to different community for the RSRP/RSRQ measurement result of UE determines that leaving macrocell covers certainly The number of the UE of lid is more than or equal to default 6th thresholding, then triggering is looked into for the location information of the institute UE positioned at macrocell edge It askes.The query result of location information of the macrocell based on the UE for being located at macrocell edge, in conjunction with being located at macrocell edge and adjacent The location information and status information of all SmallCell of cell, determines the UE's on the position of unactivated SmallCell#1 Number is more than preset third thresholding, it is determined that activation SmallCell#1.

Therefore, it when network coverage problem or network interferences problem occurs in macrocell, can trigger for UE in macrocell The inquiry of location information, and the place information inquiry result based on UE and the SmallCell information for being pre-configured the stage, determine and need The SmallCell of activation can be realized and carry out interference elimination to macrocell in time and solve the problems, such as the network coverage, and right in time Macrocell data are shunted.Data distribution herein is also possible to switch or carry separation.

Alternatively,

First, if macrocell receive belong to macro base station management and can send system information SmallCell send UE number is lower than default tenth thresholding or is more than the system message for presetting the 11st thresholding without service time, then into Operation and Maintenance The heart sends the closing instruction of the SmallCell, and the core net SmallCell is notified to be turned off.

Second, if being not belonging to macro base station management and the SmallCell of system message capable of being sent determine the UE number of itself It is more than default 11st thresholding lower than default tenth thresholding or without service time, then sending to operation and maintenance center should The closing of SmallCell indicates, and is turned off by SmallCell own base station notice core net SmallCell.

Third, if macrocell, which detects, cannot send in the SmallCell of system message UE number lower than tenth default Limit is more than default 11st thresholding without service time, then the closing instruction of the SmallCell is sent to operation and maintenance center, and Notice core net SmallCell is turned off.
