Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described, should be appreciated that embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
Here will at length describe exemplary embodiment, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless separately there is expression, the same numbers in different accompanying drawings represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the present invention.On the contrary, they are only and the example of apparatus and method as consistent in some aspects that described in detail in appended claims, of the present invention.
The embodiment of the present invention provides a kind of definite blacklist list member method, for network side, the method can be used for configuring blacklist list so that UE according to blacklist list carry out nearby region measurement complete adjacent area switch network in, for example the communication network of intensive deployment Femto base station, does not limit this embodiment of the present invention.
Definite blacklist list member's that the embodiment of the present invention provides method, is defined as blacklist list member by not meeting the adjacent area that the current access of UE of service requires, and is added in the blacklist list of UE, thereby realize the configuration to blacklist list.When UE carries out nearby region measurement when completing the switching of adjacent area, by the adjacent area in blacklist list not being measured, thereby reduce the quantity of the adjacent area of measuring, reduce the power consumption of UE; By getting rid of the adjacent area in blacklist list, realize the adjacent area only requiring for the current access that meets UE and measure, thereby improve the accuracy of the measurement of the adjacent area to switching use; In the time of reporting measurement result, also, because give the correct time in nearby region measurement result carrying out, reduce the measurement report to the adjacent area in blacklist list, and reduced the load of the bandwidth of network side, improve the utilance of bandwidth; In the time of different-frequency measure, UE can reduce the number of times that suspends current business transmission for carrying out nearby region measurement, thereby business more can be carried out normally.Below the method for determining blacklist list member in the embodiment of the present invention is elaborated.
As shown in Figure 1, for determining the flow chart of blacklist list member's method in the embodiment of the present invention, comprise step 101-step 102:
Step 101: adjudicate user equipment (UE) and Serving cell in the time of RRC connection status, the current current access requirement that whether meets described UE in the adjacent area of described Serving cell.
Step 102: when the current access that does not meet described UE when described adjacent area requires, determine that described adjacent area is the blacklist list member of described UE.
Wherein, in one embodiment, in the time determining one or more in meeting the following conditions of described adjacent area, determine that the current access that described adjacent area does not meet described UE requires:
(1), the current available interface-free resources of adjacent area does not meet the current required interface-free resources of estimating of the Qos of described UE: for example, the current available interface-free resources of adjacent area can be determined according to formula (1), this current available interface-free resources can comprise available up PRB (Physical Resource Block, Physical Resource Block) and available descending PRB;
s
1＝s
2-s
3-s
4 (1)
Wherein, s
1represent the current available interface-free resources of adjacent area; s
2represent the total interface-free resources in adjacent area; s
3represent the adjacent area interface-free resources of use; s
4represent reserved interface-free resources, this reserved interface-free resources can be first thresholding that can arrange.
Need be with explanation, can use the current available interface-free resources of prior art assessment adjacent area can meet the Qos of UE required estimate interface-free resources, the present invention does not limit at this.
(2), the current return bandwidth gear of adjacent area is preset gear higher than first: for example, when return bandwidth gear represents with four gears, gear is followed successively by from low to high: L (representing that return bandwidth is very sufficient), M (representing that return bandwidth resource is more sufficient), H (representing that return bandwidth resource is inadequate), O (representing return bandwidth resource excess load), the first corresponding default gear can be set to M gear, when this first default gear represents that return bandwidth gear when adjacent area is higher than M gear (in H or O gear time), the return bandwidth of adjacent area is inadequate, can not normal service UE, therefore can not meet the current access requirement of UE.
(3), the current hardware resource gear of adjacent area is preset gear higher than second: hardware resource comprises the hardware resources such as processor resource, storage resources and interface I/O (INPUT/OUTPUT, input-output apparatus interface).When hardware resource gear represents with four gears, gear is followed successively by from low to high: L (representing that hardware resource is very sufficient), M (representing that hardware resource is more sufficient), H (representing that BTS hardware resource is inadequate), O (representing hardware resource excess load), the second corresponding default gear can be set to M gear, when this second default gear represents that hardware resource gear when adjacent area is higher than M gear (in H or O gear time), the hardware resource of adjacent area is inadequate, can not normal service UE, therefore can not meet the current access requirement of UE.
It should be noted that, the above-mentioned first default gear and the second default gear can be the same or different.
Or, can also work as and while determining one or more in meeting the following conditions of described adjacent area, determine that the current access that described adjacent area does not meet described UE requires:
(1), the current available interface-free resources of adjacent area does not meet the current required interface-free resources of estimating of the Qos of described UE.Wherein, definite method of current available interface-free resources describes in detail above, does not repeat them here.
(2) the current required return bandwidth of estimating of Qos that, the current available backhaul bandwidth resources of adjacent area do not meet described UE: wherein, can be according to the current available backhaul bandwidth resources of the scope estimation adjacent area of the return bandwidth gear of adjacent area and the corresponding stock number of predefined gear, therefore, these available backhaul bandwidth resources can be that a scope can be also a definite numerical value.It should be noted that current available return bandwidth resource can be definite according to prior art, do not limit at this.The current required current required return bandwidth of a Qos that return bandwidth can be estimated according to user's current business of estimating of the Qos of UE, the current required return bandwidth of this Qos estimating can be a scope or a definite numerical value, it should be noted that current available return bandwidth resource can be definite according to prior art, do not limit at this; Current available return bandwidth resource is the current access requirement that does not meet UE while being less than the required return bandwidth of the Qos that estimates.
(3), the current available hardware resource of adjacent area do not meet the current business of described UE required estimate hardware resource: current available hardware resource can be a scope, also can be a definite numerical value, certainly, it should be noted that current available hardware resource can be definite according to prior art, do not limit at this.The required hardware resource of current business of UE can be a need hardware resource of estimating according to user's current business, what this was estimated need can be a scope or a definite numerical value with hardware resource, it should be noted that current available hardware resource can be definite according to prior art, do not limit at this; Current available hardware resource is the current access requirement that does not meet UE while being less than the required hardware resource of the Qos that estimates.
Wherein, the current available interface-free resources of adjacent area, return bandwidth gear, hardware resource gear can carry out cell load by instruction adjacent area and measure, for example can send to adjacent area load measurement request, instruction the first adjacent area is carried out cell load and is measured and feedback load measurement result.
Wherein, in one embodiment, one or more in can also be by the following method determine that adjacent area is blacklist list member:
1), obtain the motion track of described UE; According to the motion track of described UE, predict the moving range of described UE; In the time that described adjacent area is not in the moving range at described UE, determine that described adjacent area is the blacklist list member of described UE.Wherein, for example, can determine by obtaining the motion track of UE the moving direction of UE, the scope that then may move to according to the moving direction prediction UE of UE.For example as shown in Figure 2, Fig. 2 shows the moving range of determining UE according to angle.In Fig. 2, the direction of the moving direction of UE as shown in solid arrow in figure.Then, taking UE as angular vertex, taking the moving direction of UE as on one side, preset angles respectively delimited in both sides to the moving direction perpendicular to UE, if the preset angles of both sides can be 60 °, final prediction moving range is 120 °, as the scope between dotted arrow in Fig. 2.In Fig. 2, if adjacent area A is not in this scope of 120 °, adjacent area A is not in the moving range of UE.Further, can also further determine moving range according to the distance of adjacent area and UE, for example, in the time that the distance of adjacent area and UE is greater than distance threshold, as the adjacent area B in Fig. 2, although adjacent area in B said method determine the scope of 120 ° in, from UE apart from (being greater than above-mentioned distance threshold) too far away, therefore adjacent area B not prediction moving range in.It should be noted that, in the method for above-mentioned definite prediction moving range, the preset angles of both sides also can be different.In addition, in embodiments of the present invention, the method for any moving range that can predict UE is all applicable to the embodiment of the present invention, does not limit at this.By the moving range of prediction UE, the adjacent area in moving range is not defined as to the member of the blacklist list of UE, thereby in the time of configuration blacklist, such adjacent area is added to people in blacklist, so that UE does not measure such adjacent area while carrying out nearby region measurement.
2), obtain the current location of described UE; According to the current location of described UE, determine the distance of described adjacent area and described UE; In the time that the distance of described adjacent area and described UE is more than or equal to predetermined threshold value, determine that described adjacent area is the blacklist list member of described UE.In the time that adjacent area is far away apart from UE, UE can not be switched to this adjacent area within current or short time, by will not being defined as the member of the blacklist list of UE in the adjacent area of predetermined threshold value with the distance of UE, thereby in the time of configuration blacklist, such adjacent area is added to people in blacklist, so that UE does not measure such adjacent area while carrying out nearby region measurement.
It should be noted that, along with the variation of passage of time and environment, the state of adjacent area may change, for example the possibility of the adjacent area in blacklist list current state is good, in fact become and be not blacklist list member, and the possibility of the adjacent area in blacklist list current state is not good enough, in fact becoming is blacklist list member.Therefore after can creating blacklist list for the first time according to definite blacklist list member, preserve this blacklist list, and periodically redefine blacklist list member by this Serving cell in the time that UE is always resident in Serving cell, and the blacklist list of this UE is upgraded.Above-mentioned various definite blacklist list members' method is applicable to carry out before first establishment blacklist list, after being also applicable to have created blacklist list, blacklist list is upgraded.In one embodiment, the method for establishment or renewal blacklist list can be implemented as:
Judge whether to store the blacklist list of described UE;
In the time not storing the blacklist list of described UE, create the blacklist list of described UE, and the blacklist list member's who is defined as described UE adjacent area is added in the blacklist list of described UE;
In the time storing the blacklist list of described UE, if blacklist list member's the adjacent area that is defined as described UE not in the blacklist list of described UE time, is updated to described adjacent area in the blacklist list of described UE; If exist while not being confirmed as blacklist list member's the adjacent area of described UE in the blacklist list of described UE, described adjacent area removed from the blacklist list of described UE.
By creating blacklist list, complete the configuration of the blacklist list to UE, by upgrading blacklist list, ensure validity and the reasonability of the blacklist list of UE.
In one embodiment, upgrading after blacklist list, the blacklist list after described renewal can also sent to UE by measuring control message, instruction UE carries out incremental update to the blacklist list of self.Wherein, can only the information of renewal be sent to UE, for example, while only adding an adjacent area to blacklist list, can be only by the interpolation operational notification of He Duigai adjacent area, this adjacent area to UE, so that UE carries out incremental update, and needn't cover by blacklist list after whole renewal the blacklist list of UE self.The embodiment of the present invention realizes instruction UE the blacklist list of self is upgraded, thereby realizes the renewal of the blacklist list to UE, has ensured validity and the reasonability of the blacklist list of UE.In addition,, by incremental update, can also improve renewal speed.
Wherein, in one embodiment, at UE, in Idle state or switch to behind adjacent area, Serving cell can be deleted the blacklist list of this UE preserving, and the resource that need to safeguard to reduce Serving cell reduces the burden of Serving cell.
To sum up, the embodiment of the present invention realizes the adjacent area that the current access of UE by not meeting service requires and is defined as blacklist list member, can set up or upgrade blacklist and realize the configuration to blacklist list according to blacklist list member.When UE carries out nearby region measurement when completing the switching of adjacent area, by the adjacent area in blacklist list not being measured, thereby reduce the quantity of the adjacent area of measuring, reduce the power consumption of UE; By getting rid of the adjacent area in blacklist list, realize the adjacent area only requiring for the current access that meets UE and measure, thereby improve the accuracy of the measurement of the adjacent area to switching use; In the time of reporting measurement result, also, because give the correct time in nearby region measurement result carrying out, reduce the measurement report to the adjacent area in blacklist list, and reduced the load of the bandwidth of network side, improve the utilance of bandwidth; In the time of different-frequency measure, UE can reduce the number of times that suspends current business transmission for carrying out nearby region measurement, thereby business more can be carried out normally.
