Embodiment
As stated in the Background Art, along with the continuous development of current highway, high-speed railway, the high-speed mobile scene has become the important component part that wireless network is built.And since Doppler effect, car body to the factors such as shielding of signal, conventional high speed scenario solutions such as many sub-districts merge, install the good covering that the high speed scene can not be realized in high speed repeater etc.
At this problem, a kind of new thinking is that Femto Cell technology is applied to the high-speed mobile scene at present, promptly in train, dispose the Femto base station, adopt certain technology (as LTE technology or car ground broadband wireless technology etc.), to realize the business of normal 2G, 3G in the car as the passback mode.
In this scheme, the maximum difference of Femto base station and common scenarios base station (as ground macro base station or Home eNodeB) is that the Femto base station can be moved along with train operation in the car in the car.In this article, the base station (for example as Femto base station in the car) that the position can constantly be changed is called the mobile model base station, and the sub-district of its covering is called the mobile model sub-district.
In the application of reality, existing neighbor cell configuration scheme no longer is applicable to the application scenarios of this mobile model base station.
The embodiment of the invention has proposed a kind of configuring method for neighboring area at the mobile model base station, to realize the neighbor cell configuration demand of mobile model base station.
As shown in Figure 3, the schematic flow sheet for the configuring method for neighboring area of a kind of mobile model base station that the embodiment of the invention proposed specifically may further comprise the steps:
Step S301, obtain the translational speed information of mobile model base station.
In the application scenarios of reality, can obtain the translational speed information of mobile model base station by passback terminal or other positioning equipment according to default measuring period.
The concrete passback terminal or the selection of other positioning equipment, and the size of measuring period can adjust according to actual needs, such variation can't influence protection scope of the present invention.
Step S302, according to translational speed information, judge mobile model base station present located state.
When judging that the mobile model base station is current and be in fast state, execution in step S303;
When judging that the mobile model base station is current and be in low speed or inactive state, execution in step S304.
Judge that in order to realize above-mentioned state applied judgment rule specifically comprises following three aspects in this step:
If rule one is in pairing time interval of the first judgement cycle, the translational speed information of the mobile model base station that is obtained all is higher than threshold speed, judges the current fast state that is in mobile model base station.
If rule two is in pairing time interval of the second judgement cycle, the translational speed information of the mobile model base station that is obtained all is not higher than threshold speed, judges current low speed or the inactive state of being in mobile model base station.
If rule three is in pairing time interval of the first judgement cycle, the translational speed information of the mobile model base station that is obtained all is not higher than threshold speed, or, in pairing time interval of the second judgement cycle, the translational speed information of the mobile model base station that is obtained all is not higher than threshold speed, promptly do not satisfy simultaneously above-mentioned rule one and rule two, judge that then mobile model base station present located state remains unchanged.
In above-mentioned rule, can guarantee to get access at least a translational speed information in the cycle as sample in order to be implemented in corresponding judgment, so corresponding Cycle Length need satisfy following rule:
The first judgement cycle, the second judgement cycle was more than or equal to measuring period more than or equal to measuring period.
Step S303, terminate as the outside adjacent area of mobile model base station configuration.
In concrete enforcement scene, the adjacent area of mobile model base station is divided into two kinds:
A kind of is the sub-district of adjacent and static toward each other (or moving together each other), for example cover each Femoto sub-district in the car in the solution based on the high speed scene of Femto in the background technology, or the sub-district of same trunking administration in the Relay scene, unification is called inner adjacent area in this article.
Another kind is the sub-district of absolute rest (can not move with the mobile model base station), for example the high speed scene based on Femto in the background technology covers the outer macrocell of car in the solution, or not belonging to the sub-district that this trunking is administered in the Relay scene, unification is called outside adjacent area in this article.
Based on the setting of above-mentioned two kinds of adjacent areas of mobile model base station, in this step, corresponding processing policy comprises following four kinds:
(1) if current mobile model base station has disposed inner adjacent area and outside adjacent area, then keeps inner neighbor cell configuration, and delete outside neighbor cell configuration.
(2) if current mobile model base station does not dispose inner adjacent area and outside adjacent area, for example the situation of initialization of mobile model base station configuration or initial start then is the inner adjacent area of mobile model base station configuration, and abandons being the outside adjacent area of mobile model base station configuration.
(3) if current mobile model base station does not dispose inner adjacent area, but be configured outside adjacent area, then deleted corresponding outside neighbor cell configuration, and be the inner adjacent area of this mobile model base station configuration.
(4) if current mobile model base station has been configured inner adjacent area, but do not have the configuring external adjacent area, then keep current configuration.
Need further be pointed out that, consider the self-optimizing measurement of base station itself, so, when the mobile model base station is in high-speed moving state, the periphery situation can constantly change, the result that self-optimizing is measured often falls flat because of the variation of peripheral situation, therefore, when stopping outside neighbor cell configuration in this step, carry out the wasting of resources that unnecessary self-optimizing measurement is brought in order to reduce the mobile model base station that is under the high-speed moving state, configuration is measured in self-optimizing for the mobile model base station, and the technical scheme of the embodiment of the invention has proposed following solution equally, comprising:
(1) closes the self-optimizing measurement function of mobile model base station.
(2) the self-optimizing measuring period of increase mobile model base station.
Above-mentioned two kinds of methods can be selected in concrete application scenarios according to actual needs, specifically select any configuration mode of measuring as self-optimizing can't influence protection scope of the present invention.
Step S304, be the outside adjacent area of mobile model base station configuration.
S303 is similar with step, and based on the setting of above-mentioned two kinds of adjacent areas of mobile model base station, in this step, corresponding processing policy comprises following four kinds equally:
(1) if current mobile model base station has disposed inner adjacent area and outside adjacent area, then keeps inner neighbor cell configuration and outside neighbor cell configuration.
(2) if current mobile model base station does not dispose inner adjacent area and outside adjacent area, for example the situation of initialization of mobile model base station configuration or initial start then is inner adjacent area of mobile model base station configuration and outside adjacent area.
(3) if current mobile model base station has only disposed inner adjacent area, but not having the configuring external adjacent area, then keep corresponding inner neighbor cell configuration, is the outside adjacent area of this mobile model base station configuration simultaneously.
(4) if current mobile model base station does not dispose inner adjacent area, but having disposed outside adjacent area, then kept corresponding outside neighbor cell configuration, is the inner adjacent area of this mobile model base station configuration simultaneously.
Need be pointed out that further that in this step, the processing mode for the outside adjacent area of mobile model base station configuration specifically comprises:
Steps A, obtain the information of passback terminal current institute persistent district and adjacent area thereof by the passback terminal.
Step B, determine candidate cell according to the information of passback terminal current institute persistent district and adjacent area thereof.
Wherein, determine the rule of candidate cell, specifically comprise following three kinds:
Rule A, will return terminal current institute persistent district and the adjacent area all is defined as candidate cell.
Rule B, the macrocell that will return in terminal current institute persistent district and the adjacent area thereof are defined as candidate cell.
Rule C, will return the sub-district that signal strength signal intensity in terminal current institute persistent district and the adjacent area thereof is higher than the preset signals intensity threshold and be defined as candidate cell.
In the application of reality, can select to determine accordingly the rule of candidate cell according to the actual needs, so that select satisfactory sub-district that neighbor cell configuration is carried out in the mobile model base station, specifically select which kind of rule can't influence protection scope of the present invention.
Step C, be the outside adjacent area of homologous ray of mobile model base station with cell configuration identical in the candidate cell with the system type of the current institute in mobile model base station persistent district, and in the sub-district different in candidate cell with the system type current institute in mobile model base station persistent district, select the sub-district of the system type of the current institute in support mobile model base station persistent district, be configured to the outside adjacent area of different system of mobile model base station.
In the application scenarios of reality, be after the outside adjacent area of homologous ray of mobile model base station with cell configuration identical in the candidate cell with the system type of the current institute in mobile model base station persistent district, in order to realize adjacent area classification more accurately, the technical scheme that the embodiment of the invention proposed also comprises:
According to frequency point information, to be the homogeneous-frequency adjacent-domain of mobile model base station with the cell configuration that system type is identical and frequency is identical of the current institute in mobile model base station persistent district in the candidate cell, will be the alien frequencies adjacent area of mobile model base station with the cell configuration that system type is identical and frequency is different of the current institute in mobile model base station persistent district in the candidate cell.
S303 is similar with step, measures configuration for the self-optimizing of mobile model base station, and this step also comprises following processing procedure:
(1) the self-optimizing measurement function of unlatching mobile model base station.
(2) reduce the self-optimizing measuring period of mobile model base station.
Above-mentioned two kinds of methods can be selected in concrete application scenarios according to actual needs, specifically select any configuration mode of measuring as self-optimizing can't influence protection scope of the present invention.
Compared with prior art, the embodiment of the invention has the following advantages:
By using the technical scheme of the embodiment of the invention, to reduce unnecessary neighbor cell configuration and the measuring process in mobile model base station, can select corresponding neighbor cell configuration scheme according to the mobile status of mobile model base station self, on the one hand, can avoid in the high-speed mobile process of mobile model base station the frequent neighbor cell configuration and the measurement that cause because peripheral cell constantly changes, on the other hand, also can realize the normal configuration of its adjacent area at mobile model base station low speed or when static, thereby, unnecessary measurement and information communication process in the minimizing system, the system communication burden of avoiding the frequent change in sub-district to be brought.
Below, the application scenarios in conjunction with concrete describes the technical scheme that the embodiment of the invention proposed.
The technical scheme that the embodiment of the invention proposed is applicable to the mobile model base station in the plurality of application scenes, as wireless Relay scene, or based on high speed scene covering scene of Femto etc.
In the application of reality, the mobile model base station generally need be linked into the core net at its place by passback terminal and return network.And can be above-mentioned LTE upstream device based on the passback terminal of mobile model base station in the high speed scene covering scene of Femto, also can be the upstream device that adopts other technologies.
In wireless Relay technology, trunking has the function of ordinary terminal equipment and access device simultaneously, and at first, it links to each other with core net by macro base station wirelessly as a kind of terminal equipment; Simultaneously, can be used as a kind of access device (as being equivalent to a base station) again, manage independently sub-district, communicate by letter with wireless mode with the terminal equipment that belongs to this trunking.Belong to the mutual content of the terminal equipment of this via node and core net and all pass through (comprising data and signaling) the datum plane carrying of this trunking and core net.The pairing functional module of termination function that it is pointed out that mentioned trunking here also can be thought a kind of passback terminal.
Further, the main thought to the technical scheme that the embodiment of the invention proposed is described as follows:
At first, determine its state of living in according to the translational speed of mobile model base station.
Then, come different self-optimizing measurements and neighbor cell configuration scheme are taked in the mobile model base station, specifically comprise according to the different conditions of mobile model base station:
(1), then the self-optimizing measurement function of mobile model base station is closed or prolong measuring period, simultaneously configuring external adjacent area not if the mobile model base station is in fast state.
(2), then the self-optimizing measurement function of mobile model base station is opened or shortened measuring period, simultaneously the configuring external adjacent area if the mobile model base station is in low speed/inactive state.
Wherein, what need further specify is that the outside neighboring BS information of mobile model base station can obtain by the passback terminal.
For the technical scheme to the embodiment of the invention is carried out specific description more, below, at determining of mobile model base station, three processing procedures in concrete configuration process and outside adjacent area describe as follows respectively:
One, determines its state of living in according to mobile model base station translational speed.
The translational speed information of mobile model base station can be obtained by the passback terminal, because the passback terminal generally adopts wireless channel communication with return network, therefore, can come reckoning speed by the Doppler frequency deviation of measuring received signal.Certainly, in concrete application scenarios, also can obtain by other equipment, for example: GPS(Global Positioning System, global positioning system) positioning equipment such as equipment, consider that above-mentioned translational speed information obtain manner relates generally to existing technical finesse flow process, so, do not repeat them here.
Mobile model base station state Rule of judgment of living in: periodically obtain the translational speed of mobile model base station, when the translational speed of measuring in continuous a period of time all is higher than threshold speed, judge that the mobile model base station enters high-speed moving state, and the translational speed of measuring in continuous a period of time is not when all being higher than this threshold speed, judge that then the mobile model base station enters low speed/inactive state, when top two conditions do not satisfy, determine that mobile model base station state remains unchanged.
The schematic diagram of concrete state judgement flow process comprises step down as shown in Figure 4:

And the concrete numerical values recited of above-mentioned parameter can be adjusted according to actual needs, and such variation does not influence protection scope of the present invention.
Step S402, reaching measurement period T

If greater than, execution in step S404 then;
If not greater than, execution in step S409 then.
Step S404, judge current low speed or the inactive state of whether being in mobile model base station.
If, execution in step S405 then;
If not, then skip to step S413.
Step S405, translational speed information V is lasting greater than threshold speed V
ThTime size increase T
P
Simultaneously, V continues to be not more than threshold speed V if current record has translational speed information

Step S406, the current translational speed information V of judgement continue greater than threshold speed V

If surpass, execution in step S407 then;
If do not surpass, then return step S402.
Step S407, the state that the mobile model base station is current are adjusted into fast state.
Step S408, empty current translational speed information V and continue greater than threshold speed V
ThTime, and return step S402.
Step S409, judge the current fast state that whether is in mobile model base station.
If, execution in step S410 then;
If not, then skip to step S408.
Step S410, translational speed information V is continued to be not more than threshold speed V
ThTime size increase T
P
Simultaneously, if current record has translational speed information V to continue greater than threshold speed V
ThTime, then should the time interocclusal record zero clearing.
Step S411, the current translational speed information V of judgement continue to be not more than threshold speed V
ThTime whether surpassed second and judged period T

If surpass, execution in step S412 then;
If do not surpass, then return step S402.
Step S412, the state that the mobile model base station is current are adjusted into low speed or inactive state.
Step S413, empty current translational speed information V and continue to be not more than threshold speed V
ThTime, and return step S402.
It is to be noted; above-mentioned inactive state is the another kind of appellation of lower-speed state; also can be a kind of state mutually arranged side by side with lower-speed state; and; inactive state can refer to that translational speed is 0 no mobile status; the state that also can refer to translational speed very low (being lower than the certain speed value), such title changes can't influence protection scope of the present invention.
Two, the different conditions according to the mobile model base station comes different self-optimizing measurements and neighbor cell configuration scheme are taked in the base station.
The Femto base station is in equipment running process, generally all needing to carry out self-optimizing measures, comprise and periodically carry out Interference Detection, according to disturbed condition configuration Femto base station frequency point and scrambler, or adjustment pilot tone and maximum power, reduce interference with grand network, and neighboring area signal detects, to carry out the operation of aspects such as neighboring BS information renewal, consider that corresponding processing procedure relates generally to existing technical finesse flow process, so, do not repeat them here, wherein, self-optimizing measuring process generally adopts the mode of periodically carrying out to realize.
Concrete self-optimizing measurement and neighbor cell configuration scheme are as follows:
(1) enter low speed/inactive state when the mobile model base station, its self-optimizing measurement function is opened or shortened measuring period, simultaneously, the inside and outside adjacent area of configuration mobile model base station.
When the mobile model base station enters low speed/inactive state, for example, in high speed scene covering scene based on Femto, when train is stopped platform, general car door opening, need to consider between mobile model base station (being Femto base station in the car) and the outer macro base station of car, and the interference between the mobile model base station of different trains, therefore, need open the self-optimizing measurement function or shorten self-optimizing measuring period, so that make the mobile model base station carry out optimizing and revising of self, avoid interference according to corresponding measurement result.
In addition, also to consider the mobility demand of the outer macrocell of mobile model sub-district and car, therefore, except the adjacent area, inside of configuration mobile model base station, also need the configuring external adjacent area.
(2) enter high-speed moving state when the mobile model base station, its self-optimizing measurement function is closed or prolong measuring period, simultaneously, do not dispose the outside adjacent area of mobile model base station, only dispose its inner adjacent area.
The situation that the mobile model base station is in high-speed moving state generally appears at the bullet train scene, train is when operation, because the sealing car body is to the decay of signal, generally need not consider between mobile model base station (being Femto base station in the car) and the outer macro base station of car, and the interference between the mobile model base station of different trains, and only need consider the interference between each mobile model base station in the car, in addition, each mobile model base station general position is fixed in the car, and being wire distributes, therefore, can prolong self-optimizing measuring period or close the self-optimizing measurement function, reduce the consumption that the system resource of being brought is measured in unnecessary self-optimizing.
Simultaneously, because the macrocell that the mobile model base station is passed in the high-speed mobile process constantly changes, so, needn't give the mobile model base station configuration outside adjacent area again, can avoid the mobile model base station frequently to change neighbor cell configuration like this, also avoid therefore causing the terminal equipment of its service frequently to be measured, or bring unnecessary sub-district gravity treatment or switching.
Wherein, if close the self-optimizing measurement function of mobile model base station, so, its configurations such as selected frequency, code word when low speed/inactive state will be continued to use in the mobile model base station when high-speed moving state, and, then only select its selected inner adjacent area when low speed/inactive state for the neighbor cell configuration of mobile model base station.
In concrete enforcement scene, if the mobile model base station is opened or restarted, then need start initial configuration in high-speed moving state, the flow process of corresponding initial configuration is a prior art, no longer explanation here.
In high-speed moving state, new mobile model base station is opened the self-optimizing that also can trigger the mobile model base station that is adjacent and is measured.
The schematic flow sheet of corresponding liberalization configuration adjustment flow process specifically may further comprise the steps as shown in Figure 5:
Result's input of the current state of step S501, wait mobile model base station.
After having determined the current state of mobile model base station to step S413 by aforesaid step S401, both realized the result input of current state of mobile model base station after, execution in step S502.
Step S502, judge whether the current state of mobile model base station is fast state.
If, execution in step S503;
If not, execution in step S505.
Step S503, delete the outside adjacent area of this mobile model base station.
If be configured inner adjacent area and outside adjacent area before this mobile model base station, the inside neighbor cell configuration before then continuing to use, and delete outside adjacent area.
And if this mobile model base station does not dispose inner adjacent area and outside adjacent area before, then be the inner adjacent area of this mobile model base station configuration, still, in the processing procedure of this step, can not carry out the configuration of outside adjacent area.
Step S504, the self-optimizing measurement function of this mobile model base station is closed or prolong measuring period.
After finishing the processing of this step, return step S501.
Step S505, dispose the outside adjacent area of this mobile model base station.
If be configured inner adjacent area before this mobile model base station, the inside neighbor cell configuration before then continuing to use simultaneously, disposes the outside adjacent area of this mobile model base station.
And if this mobile model base station does not dispose inner adjacent area before, then be the inner adjacent area of this mobile model base station configuration, simultaneously, dispose the outside adjacent area of this mobile model base station.
Step S506, the self-optimizing measurement function of this mobile model base station is opened or shortened measuring period.
After finishing the processing of this step, return step S501.
