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

Secondly, macrocell all UE in macrocell initiate random access request and are calculated each The corresponding Timing Advance of UE (Timing Advance, TA), and true based on the TA of each UE Fixed distance between each UE and base station.

Finally, macrocell based between the corresponding AOA of each UE and each UE and base station away from From the positional information determining all UE in macrocell.

Step 220: the Query Result of the positional information based on UE all in macrocell for the macrocell, in conjunction with grand The positional information of all SmallCell and status information in cell, determine the SmallCell needing to activate.

Concrete, the Query Result of the positional information based on UE all in macrocell for the macrocell, in conjunction with grand little The positional information of all SmallCell and status information in district's coverage, however, it is determined that unactivated The number of the UE on the position of SmallCell exceedes default 3rd thresholding, it is determined that activate unactivated SmallCell。

For example, refering to shown in Fig. 3, in the pre-configured stage, macrocell obtains from operation maintenance center and covers model Enclose the identification information of interior all SmallCell, positional information, status information, wherein, SmallCell#0, SmallCell#1, SmallCell#2, SmallCell#3 are unactivated SmallCell.When macrocell is true The fixed handling capacity of self, more than or equal to presetting the first thresholding, triggers the position letter for UE all in macrocell Breath inquiry.The Query Result of the positional information based on UE all in this cell for the macrocell, in conjunction with in macrocell The positional information of all SmallCell and status information, wherein, comprise 1 user in SmallCell#0, SmallCell#1 comprises 1 user, SmallCell#2 comprises 3 users, in SmallCell#3 Comprise 2 users, determine that the number of the UE on the position of unactivated SmallCell#2 at most and exceedes The 3rd thresholding preset, it is determined that activate SmallCell#2.

Therefore, when macrocell network is busy, when being in congestion state, can trigger for UE in macrocell The inquiry of positional information, and based on the place information inquiry result of UE and the SmallCell in pre-configured stage Information, determines the SmallCell needing to activate, is capable of shunting the data of macrocell in time, rises To the effect sharing macrocell load.Data distribution herein can be switching or carrying separates, wherein, Switching refers to, after SmallCell activates, data surface and the chain of command of UE all be transferred to SmallCell In；And carry separation and refer to after SmallCell activates, the chain of command carrying of UE is retained in macrocell In, and all or part of data surface business is transferred in SmallCell.

If it needs to be noted that now macrocell determines have at least two to determine unactivated SmallCell's The number of the UE on position exceedes default 3rd thresholding, it is determined that activate the SmallCell meeting condition.

Further, if macrocell determines macrocell and determines that the SmallCell activating belongs to same base Stand, then directly initiate SmallCell and activate；

Or,

If macrocell determines macrocell and determines that the SmallCell activating belongs to different base stations, then to behaviour Make maintenance centre and send SmallCell activation request, operation maintenance center is initiated SmallCell and activates.

Additionally, be specifically divided into three kinds of situations in the deactivation to SmallCell for the idle:

One, if macrocell receives belongs to the SmallCell that macro base station manages and can send system information The UE number sending disappears less than default 4th thresholding or the system without exceeding default 5th thresholding service time Breath, then send the closedown instruction of this SmallCell, and notify that core net should to operation maintenance center SmallCell is turned off.

Its two, manage and the SmallCell of system message can be sent determine self if being not belonging to macro base station UE number is less than default 4th thresholding or without exceeding default 5th thresholding service time, then in Operation and Maintenance The heart sends the closedown instruction of this SmallCell, and should by this SmallCell own base station notice core net SmallCell is turned off.

Its three, if macrocell detects in the SmallCell that can not send system message UE number less than pre- If the 4th thresholding or without exceeding default 5th thresholding service time, then sending to operation maintenance center should The closedown instruction of SmallCell, and notify that this SmallCell of core net is turned off.

It refering to shown in Fig. 4, in the embodiment of the present invention, is pointed to macrocell edge or adjacent with macrocell The detailed process that SmallCell is managed is:

In the pre-configured stage, macrocell obtains from operation maintenance center and is positioned at macrocell edge and neighbor cell The identification information of all SmallCell, positional information, status information.

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

Concrete, macrocell judges that the way leaving the UE that macrocell covers is:

If macrocell receives the A2 event reporting for UE, but when reaching the time threshold preset It is not received for the A3 event that UE reports, it is determined that UE is leaving the coverage of macrocell.

Wherein, A2 event is Serving cell for the measurement result of the RSRP/RSRQ of UE less than presetting the Seven thresholdings, A3 event is that the measurement result for the RSRP/RSRQ of UE for other co-frequency cells is higher than service Cell is for default 8th thresholding of the measurement result of the RSRP/RSRQ of UE.

Step 410: if it is determined that leaving the number of the UE that macrocell covers more than or equal to default 6th Limit, then macrocell initiates the place information inquiry for the UE being positioned at macrocell edge.

At this point, it is emphasized that triggering macrocell carries out the place information inquiry of the UE at macrocell edge It is to report A2 event and do not report the UE number of A3 event to reach default low thresholding.Therefore, on Report A2 but do not report the UE of A3 event leaving the covering of macrocell, report the UE of A3 event then Represent and be in macrocell and the intersection with macrocell neighbor cell.

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

First, each UE that macrocell is positioned at macrocell edge by smart antenna receiver is corresponding AOA；

Secondly, macrocell is initiated random access request to the UE being positioned at macrocell edge and is calculated each The corresponding TA of individual UE, and the TA based on each UE determine between each UE and base station away from From.

Finally, macrocell based between the corresponding AOA of each UE and each UE and base station away from From the positional information determining the UE being positioned at macrocell edge.

Step 420: the Query Result of the positional information based on the UE being positioned at macrocell edge for the macrocell, knot Close positional information and the status information of all SmallCell being positioned at macrocell edge and neighbor cell, determine Need the SmallCell activating.

Concrete, the Query Result of the positional information based on the UE being positioned at macrocell edge for the macrocell, in conjunction with It is positioned at positional information and the status information of all SmallCell of macrocell edge and neighbor cell, however, it is determined that The number of the UE on the position of a unactivated SmallCell exceedes default 9th thresholding, it is determined that activate One SmallCell.

For example, refering to shown in Fig. 5, in the pre-configured stage, macrocell is positioned at grand from operation maintenance center's acquisition The identification information of all SmallCell of cell edge and neighbor cell, positional information, status information.Its In, SmallCell#0, SmallCell#1 are unactivated SmallCell.

Here but the UE in SmallCell#1 reports A2 event does not has when reaching the time threshold preset Report A3 event, show that this UE is leaving macrocell and covering, and on the UE in SmallCell#1 Reported A3 event, i.e. the measurement result of cell A is better than the measurement result of macrocell, it is judged that this UE just locates In the intersection of macrocell and cell A, as shown in Figure 5.

Macrocell according to different districts for UE RSRP/RSRQ measurement result determine from determine from Open the number of the UE that macrocell covers more than or equal to presetting the 6th thresholding, then trigger for being positioned at macrocell limit The place information inquiry of the institute UE of edge.Macrocell is based on the positional information of the UE being positioned at macrocell edge Query Result, in conjunction with positional information and the shape of all SmallCell being positioned at macrocell edge and neighbor cell State information, determines that the number of the UE on the position of unactivated SmallCell#1 exceedes default the 3rd Limit, it is determined that activate SmallCell#1.

Therefore, when network coverage problem or network interferences problem occurs in macrocell, can trigger for grand The inquiry of UE positional information in cell, and based on the place information inquiry result of UE and pre-configured stage SmallCell information, determines the SmallCell needing to activate, is capable of disturbing macrocell in time The problem eliminating and solving the network coverage, and in time macrocell data are shunted.Data distribution herein Also can be switching or carrying separation.

Or,

One, if macrocell receives belongs to the SmallCell that macro base station manages and can send system information The UE number sending disappears less than default tenth thresholding or the system without exceeding default 11st thresholding service time Breath, then send the closedown instruction of this SmallCell, and notify that core net should to operation maintenance center SmallCell is turned off.

Its two, manage and the SmallCell of system message can be sent determine self if being not belonging to macro base station UE number is less than default tenth thresholding or without exceeding default 11st thresholding service time, then to Operation and Maintenance Center sends the closedown instruction of this SmallCell, and should by this SmallCell own base station notice core net SmallCell is turned off.

Its three, if macrocell detects in the SmallCell that can not send system message UE number less than pre- If the tenth thresholding or without exceeding default 11st thresholding service time, then sending to operation maintenance center should The closedown instruction of SmallCell, and notify that this SmallCell of core net is turned off.
