Uplink and downlink packet loss in the packet loss field that the MR message of each user equipment includes, target where reflection user equipment
The packet loss of some region point of cell, the packet loss of Target cell where can not reflecting user equipment, therefore the network equipment needs
The average value of packet loss in the MR message of all user equipment to report in Target cell is counted, and then determines losing for Target cell
Packet rate.The network equipment can judge the current signal quality situation of Target cell and service bearer by the packet loss of Target cell
Ability can determine whether that Target cell current signal quality is bad and target cell traffic is held at this time if Target cell packet loss is higher
Loading capability is poor, Target cell current signal quality is can determine whether if Target cell packet loss is relatively low preferably and Target cell at this time
Service bearer ability is stronger.
S203：The network equipment is determined according to the packet loss of the Target cell at least one Target cell
Including Target cell packet loss be less than pre-set first threshold value Target cell.
In the embodiment of the present invention, the network equipment pre-sets one for weighing whether Target cell packet loss meets switching
First threshold value of standard, packet loss are unsatisfactory for switching standards higher than the Target cell of the first threshold value, and the network equipment is according to system
It is pre- to determine that the packet loss for the Target cell that at least one Target cell includes is less than for the packet loss of Target cell after meter
The Target cell for the first threshold value being first arranged.
S204：The packet loss for the Target cell that at least one Target cell is included by the network equipment is less than pre-
The Target cell for the first threshold value being first arranged is determined as meeting the Target cell of switching standards.
In the embodiment of the present invention, the Target cell that the network equipment can be by packet loss higher than the first threshold value is described at least one
It is deleted in a Target cell, and then the packet loss for the Target cell that at least one Target cell includes is less than and is set in advance
The Target cell for the first threshold value set is determined as meeting the Target cell of switching standards.
In the embodiment of the present invention, MR message of the network equipment according to the cell-of-origin is described below in detail, described
The process for the Target cell for meeting switching standards is determined at least one Target cell.

The TA values and PHR values included can accurately determine edge customer equipment in cell-of-origin.
In the embodiment of the present invention, TA values are the uplink sending time of user equipment, therefore the network equipment can be determined by TA values
Distance of the user equipment apart from source cell base station in cell-of-origin, user equipment TA values then illustrate greatly user equipment apart from cell-of-origin base
It stands farther out, you can judge that user equipment is in the fringe region of cell-of-origin.It is used as by selection TA values and judges that cell-of-origin edge is used
The criterion of family equipment avoids the false judgment for determining Target cell by RSRP values merely, because can determine that source is small by TA values
Absolute distance of the user equipment apart from source cell base station in area will not be caused by the RSRP that blocking is formed and judge that inaccuracy is asked
Topic.The PHR values are the surplus of maximum transmission power of the user equipment relative to configuration in cell-of-origin, this surplus indicates cell-of-origin
Transmission power estimated value and configuration maximum transmission power difference, the measurement data can be used for carry out user equipment transmitting
Power analysis, the PHR values of user equipment are small to illustrate that user equipment has moved away from source cell base station in cell-of-origin, that is, is in cell-of-origin
Whether fringe region is in cell-of-origin edge by the TA values and PHR value Conjoint Analysis user equipment of user equipment in cell-of-origin
Region can more accurately determine edge customer equipment in cell-of-origin, be improved by switching accurate edge customer equipment
The reasonability of user equipment switching.
S303：The network equipment determine TA values be less than pre-set second threshold value, and PHR values be more than pre-set
Third threshold value user equipment.
In the embodiment of the present invention, the second threshold value of user equipment TA values in cell-of-origin and PHR values are pre-set
It is advance to determine that TA values are less than by the TA values and PHR values in user equipment MR message in cell-of-origin for third threshold value, the network equipment
The second threshold value being arranged, and PHR values are more than the user equipment of pre-set third threshold value, that is, pass through TA values and PHR values
Joint determines the user equipment in cell-of-origin edge.
S304：The network equipment is more than pre-set second threshold value by the TA values, and PHR values are less than in advance
The Target cell ID for including in the MR message of the user equipment of the third threshold value of setting, determination are corresponding with the Target cell ID
Target cell.
In the embodiment of the present invention, the network equipment determines in cell-of-origin after edge customer equipment, passes through edge customer equipment
MR message in include Target cell ID, determine corresponding with Target cell ID Target cell, that is, determine edge use
The adjacent cell of family equipment.Due to needing to carry out the cell-of-origin of load balancing to be finally by cutting edge customer equipment in cell-of-origin
Target cell realization is changed to, therefore the embodiment of the present invention is used by accurately determining edge customer equipment, and then by edge
The MR message of family equipment determines the Target cell for carrying out load balancing to cell-of-origin, by switching accurate edge customer
Equipment and then the reasonability for improving user equipment switching, and then the handover success rate of edge customer equipment can be improved.
