With reference to figure 1, show the flow chart of a kind of plot joint dispatching embodiment of the method for the application, the present embodiment can comprise the following steps:
Step 100: receive the measurement result that the affiliated macro base station of each UE and micro-base station send, described measurement result comprises: the macro base station that described each UE measures respectively and the down-run survey result of micro-base station.
In actual applications, the application can be applied on plot joint dispatching device.Shown in figure 2, it is this method embodiment structural representation of a concrete scene in actual applications.Wherein, plot joint dispatching device can be an independent logic function unit, also can and macro base station (Macro eNodeB) scheduler concentrate in together realization, also can be respectively and macro base station (Macro eNodeB) scheduler, micro-base station (small cell) scheduler three concentrate in together realization.Wherein, in actual applications, UE measures macro base station and micro-base station respectively, and measurement result is reported to the corresponding base station-macro base station in UE persistent district or micro-base station, and macro base station scheduler and micro-base station dispatcher report measurement result respectively plot joint dispatching device again.If plot joint dispatching device, macro base station scheduler and micro-base station dispatcher three concentrate in together realization, plot joint dispatching device also can directly read relevant metrical information for oneself from the respective memory locations of macro base station scheduler and micro-base station dispatcher.
Wherein, each UE, in the time measuring, can be specifically that the downlink reference signal of macro base station and micro-base station is measured, and measurement result is exactly the quality of each macrocell of each UE measurement and the downlink reference signal of Microcell.
Wherein, each UE also can be after measuring the downlink reference signal of macro base station and micro-base station, the macro base station or the micro-base station that the measurement result of community that meets preset signals quality requirements are reported respectively to UE persistent district, for example signal quality must not be lower than certain threshold value.
Wherein, each UE also can be after measuring the downlink reference signal of macro base station and micro-base station, the satisfied default macrocell of the first difference threshold and/or the downlink signal quality of Microcell measured are reported to the corresponding base station-macro base station in UE persistent district or micro-base station, and this first difference threshold is: the threshold value of the macrocell that other macrocells and/or other Microcells and described each UE are resident and/or the signal quality difference of Microcell.That is, the difference of the measurement result of other community and the measurement result of its persistent district is in the thresholding of setting, and each UE reports the measurement result of these specific cells macro base station or micro-base station of UE persistent district.
Wherein, each UE also can be by the signal quality difference meeting between other macrocells of preset difference value condition and other Microcells and its resident initial macrocell and initial Microcell, report macro base station or micro-base station of UE persistent district, these other macrocells and other Microcells that meet preset difference value condition are: signal quality difference is greater than the community of default the second difference threshold.That is, UE resides under certain community, and the difference of the measurement result of other community and the measurement result of persistent district set thresholding in, UE reports difference corresponding these communities macro base station or micro-base station of UE persistent district so.
After UE measures the downlink reference signal of macro base station or micro-base station, measurement result is the down-run survey result of each macro base station and/or micro-base station.And the measurement result that the macro base station of UE persistent district or micro-base station can report according to UE judges that UE receives the signal quality of the downlink data of different districts.Macro base station and micro-base station can be divided into UE respectively following two classes so: the first kind is, except the resident community of UE, UE does not meet predefined threshold value to the measuring-signal of other community; Equations of The Second Kind is, except the resident community of UE, UE also has the measuring-signal of other community to meet the threshold value of setting.Wherein, the threshold value of this setting, can be an absolute threshold value, can be also a relative threshold value, for example, and with the difference of the measuring-signal of the persistent district of UE.
Be understandable that so, macro base station or micro-base station can select the UE and the relevant measurement result that meet Equations of The Second Kind condition to report plot joint dispatching device.Also the measurement result of receiving all can be reported to plot joint dispatching device.
In addition, it should be noted that, except the measurement result of above-mentioned UE, the measurement result of macro base station or micro-base station can also, by information reportings such as the numbers of users having accessed of cell capacity, macrocell or the Microcell of uplink and downlink data volume, macrocell or the Microcell of UE to plot joint dispatching device, be judged according to informixs such as the numbers of users having accessed of cell capacity, macrocell or the Microcell of uplink and downlink data volume, macrocell or the Microcell of UE by plot joint dispatching device.
Step 101: obtain the affiliated macro base station of active user's terminal UE or the measurement result of micro-base station, and, the measurement result of other macro base stations and micro-base station; Described measurement result is the quality of the downlink reference signal of each macro base station and/or micro-base station.
In this step, if for current some user terminal UE, for example, for the UE that meets aforementioned Equations of The Second Kind condition, exist the downlink signal quality of other macrocells or Microcell better than the downlink signal quality of the resident macrocell of this UE or Microcell, plot joint dispatching device can carry out combined dispatching to it so.Concrete, plot joint dispatching device can be directly gets macro base station under this UE persistent district or the measurement result of micro-base station from the measurement result that macro base station or micro-base station report, and, the measurement result of other macro base stations and/or micro-base station.
Step 102: judge according to described measurement result whether current UE needs to switch, if so, enter step 103.
Plot joint dispatching device judges according to the measurement result getting whether this UE needs to carry out community switching again, concrete, judge according to described measurement result whether described current UE needs the detailed process of switching, can judge whether that the downlink signal quality of target macro community or target Microcell is greater than the downlink signal quality of the resident macrocell of this UE or Microcell.If exist downlink signal quality than the better community of the resident macrocell of UE or Microcell, UE can be switched to this so and have the community of better downlink signal quality.Have multiplely if there is the target macro community of better downlink signal quality or target Microcell, can determine that so any one target macro community or target Microcell switch.Or plot joint dispatching device also can preferentially be determined macrocell, selects the best community of downlink signal quality to switch in the macrocell satisfying condition; In like manner, also can pay the utmost attention to Microcell.Again or, plot joint dispatching device also can be in the situation that downlink signal quality be all identical, considers the cell capacity of macrocell or Microcell, preferentially determines that cell capacity compare great community is as target macro community or Microcell.
Further, for the UE that meets aforementioned Equations of The Second Kind condition, when its downlink data receiving, when the signal that different macrocells or Microcell send arrives this UE, the situation of its signal quality is much the same.So, plot joint dispatching device can also be informed by the measurement situation of the up transmitted signal of the UE receiving in the macro base station of UE persistent district or micro-base station, or the measurement situation of the up transmitted signal of the UE receiving is informed plot joint dispatching device by the base station of UE pre-switch community, measurement result can also comprise in this case: quality of uplink signal, this quality of uplink signal is the quality of uplink signal of the resident initial macrocell of current UE or initial Microcell.
So, judge according to described measurement result whether described current UE needs to switch, and can also comprise: judge whether that the quality of uplink signal of target macro community or target Microcell is greater than the quality of uplink signal of the resident macrocell of current UE or Microcell.If there is a target macro community or target Microcell, its quality of uplink signal is better than the resident macrocell of UE and Microcell, and plot joint dispatching just can judge that this UE need to switch this target macro community or target Microcell so.
If in actual applications, exist multiple downlink signal quality and quality of uplink signal to be all better than target macro community or the target Microcell of the resident macrocell of UE or Microcell, UE can preferentially select downlink signal quality best that target macro community or target Microcell so, or also can preferentially select quality of uplink signal best that target macro community or target Microcell.If exist the good and bad degree of up/down row signal quality of multiple target macro community and target Microcell identical, can determine that so any one target macro community or target Microcell switch.
Step 103: notify described UE by target macro community or target Microcell.
After plot joint dispatching device has been determined to be switched target macro community or target Microcell, by cell ID or other can unique definite target macro community or the information of target Microcell notify to current UE so that this current UE switches to this target macro community or up-downgoing transfer of data is carried out in target Microcell.In the situation that current UE switches to target macro community or target Microcell, can on target macro community or target Microcell, carry out transmitting uplink data and downlink data transmission with current UE.
Visible, in the embodiment of the present application, plot joint dispatching device can receive the measurement result to macro base station and micro-base station that UE reports simultaneously, in dispatching, can consider the downlink signal quality of macro base station and micro-base station simultaneously, all measurement result is reported to the mode of plot joint dispatching device by macro base station and micro-base station, reduce the interactive information between macro base station and micro-base station, determine the less transmission plan of interference by plot joint dispatching device, to reach the maximized object of power system capacity, also can increase user's communication experiences simultaneously.Further, in the process of determining target switching cell, not only consider descending interference, also considered uplink interference, realized whole system uplink and downlink and disturbed less object.Further, can also according to community user number number, adjust dynamically the transmitting power of base station, reduced the energy resource consumption of whole system, played green, environmental protection and energy-conservation object.
