Embodiment one
Referring to Fig. 1, Fig. 1 is load balancing schematic flow sheet between the embodiment of the invention one small area.Concrete steps are:
The duty ratio of residential quarter can be determined according in the following information one or several: eNB terminal equipment linking number information, eNB physical resource block message, business state information.Be the altogether ratio of spendable Physical Resource Block of the Physical Resource Block that takies in the residential quarter and residential quarter such as the duty ratio of determining by eNB physical resource block message.If when using a plurality of parameter informations to determine the duty ratio of residential quarter, can weight be set for the cell load ratio that each parameter information calculates, finally calculate a duty ratio.In concrete the use, specifically use the duty ratio of which calculation of parameter as being used for duty ratio relatively among the application, can be arranged according to concrete operating position by the user.
Preset in the step 101 and cut out duty ratio greater than default energy-conservation duty ratio, the default duty ratio that cuts out is carried out pre-configured with default energy-conservation duty ratio according to concrete environment for use, wherein, whether whether the default duty ratio that cuts out is used for weighing this residential quarter and transships, need the user is cut into other residential quarters; Default energy-conservation duty ratio be used for weighing this residential quarter be the user seldom, even do not have the user, can enter the standard of sleep pattern.
When the duty ratio of this residential quarter when cutting out duty ratio, illustrates this cell-overload greater than default, need to seek Target cell and carry out the user and switch.
Before determining the incision Target cell, need to know the duty ratio of each neighbor cell, its process is: this eNB sends to each adjacent residential quarter with the information of this cell-overload, and when the residential quarter that is in work received these overload messages, the duty ratio that this residential quarter is current sent to this eNB; When the residential quarter that is in sleep pattern received this overload message, the state that this residential quarter is in sleep pattern sent to this eNB, makes this eNB know the current title that is in the residential quarter of sleep pattern.
Whether this eNB determines first to exist in the duty ratio of the work residential quarter that obtains less than default incision duty ratio, if exist, then select the residential quarter of duty ratio minimum to cut the residential quarter as target, and the user of this residential quarter is cut this Target cell by default load balancing rule part.Wherein, the default duty ratio that cuts out is greater than default incision duty ratio, and default load balancing rule is determined according to concrete applied environment, is cut into Target cell such as some users with this residential quarter, reaches this residential quarter nonoverload, the effect that Target cell carries only etc.
By adjusting duty ratio greater than the default handover operation parameter that cuts out between duty ratio and incision Target cell, the user is more prone to from the overloaded cells to the switching target small area, it is more difficult to make switching target small area switch to the switching of overloaded cells, with transfer and the equilibrium that realizes loading between overloaded cells and the switching target small area.The handoff parameter of minizone mainly refers to the bias that switch the minizone.
