Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of method and device that carries out frequency self-configuring.
Background technology
Micro-base station is by IP (Internet Protocol, iso-ip Internetworking protocol ISO-IP) network connection mobile operator network, mobile terminal expects to reside in particularly CSG (Closed Subscriber Group of micro-base station, closed user group) micro-base station under pattern is to obtain preferential on rate, but being selected into of micro-base station is subject to following two factors impact.
First: cell reselection principle.
Be example with GSM (Global System for Mobile communication, global system for mobile communications), the cell reselection behavior of mobile terminal is determined by cell reselection parameters C2 value.
Cell reselection behavior is subject to PI (Cell Reselect Parameter Indication, cell reselection parameters instruction) impact, in the time of PI=0, adopts C2=C1 criterion to carry out cell reselection judgement; In the time of PI=1, adopt C2 criterion to carry out cell reselection judgement.Detailed process is: when Serving cell and adjacent cell LAC (Location Area Code, Location Area Code) configure when identical, while exceeding continuous 5 seconds of the C2 value of current service cell as the C2 value of adjacent area, mobile terminal is selected into this adjacent area; In the time that Serving cell is different with adjacent cell LAC configuration, while exceeding the C2 value of Serving cell and the cell reselection lagged value sum of Serving cell as the continuous 5s of C2 value of adjacent area, mobile terminal is selected into this adjacent area.
Second: BCCH (the Broadcast Control Channel that needs Jiang Zhe community, Broadcast Control Channel) frequency is configured in BA (Broadcast Control Channel Allocation, Broadcast Control Channel distribute) 1 table of adjacent area.
Because micro-number of base stations is numerous and position is unfixing, can not as grand net, adopt manual configuration mode, therefore in prior art, introduce SON (Self Organized Network, self-organizing network) thought, automatically the frequency of Jiang Zhe community is configured to identical with the adjacent area of adjacent area (being called dominant frequency point configures with reference to adjacent area), expect to solve the abnormal problem of being selected into of micro-base station with this, but it is basis for estimation mainly with the watt level of intercepting of this community that the configuration of dominant frequency point is selected with reference to adjacent area, its result is difficult to solve cell reselection and is selected into problem, as depicted in figs. 1 and 2, in figure, femtocell represents micro-base station, MacroCell1 and MacroCell2 represent two adjacent with it macro stations, Fig. 1 and Fig. 2 have represented that respectively micro-base station and adjacent macro station cover schematic diagram, wherein the BA1 of MacroCell1 table comprises F0 and F01, F02, F03, F04, ...., the frequencies such as F0n, the BA1 table of its MacroCell2 is respectively F1 and F11, F12, F13, F14, ...., the frequencies such as F1n, the BA1 table of MacroCell1 and MacroCell2 occurs simultaneously for empty.Suppose that femtocell is greater than MacroCell2 to the power of intercepting of MacroCell1, MacroCell1 is as the reference adjacent area of this community dominant frequency point configuration.
In Fig. 1, suppose that femtocell working frequency points is F01 (getting frequency on the BA1 table of MacroCell1), mobile terminal originally resided in MacroCell2 adjacent area, mobile terminal enters the scope that micro-base station covers from left to right now, but in the BA1 table due to MacroCell2, there is no F01 frequency, mobile terminal can not be selected into micro-base station.
In Fig. 2, although femtocell is greater than the power that listens to Macrocell2 the working frequency points of self is configured to F01 because listening to the power of MacroCell1, but in the residing position of mobile terminal, if the C2 value of MacroCell2 is greater than MacroCell1, mobile terminal resides in MacroCell2 according to cell reselection priority, and there is no F01 frequency in the BA1 of MacroCell2 table, can not be selected into equally micro-base station.Above two kinds of situations, mobile terminal all can not normally be selected into micro-base station, causes mobile terminal in prior art to be selected into the success rate of micro-base station lower.

Embodiment
The embodiment of the present invention provides a kind of method and device that carries out frequency self-configuring, micro-base station selects the BCCH frequency of a BCCH frequency as affiliated subdistrict, micro-base station from the Neighboring Cell List BCCH frequency of at least two adjacent areas occurs simultaneously, thereby improved mobile terminal and be selected into the success rate of micro-base station.
Below in conjunction with Figure of description, the embodiment of the present invention is described in detail.
As shown in Figure 3, a kind of method flow diagram that carries out frequency self-configuring that the embodiment of the present invention provides, the method comprises:
Step 301: micro-base station determines that according to the Neighboring Cell List of at least two adjacent areas that obtain the BCCH channel of broadcast control frequency of Neighboring Cell List occurs simultaneously;
Step 302: the BCCH frequency of a BCCH frequency as affiliated subdistrict, described micro-base station selected in described micro-base station in described BCCH frequency occurs simultaneously.
In the embodiment of the present invention, micro-base station comprises the low power base station such as femto base station, Home eNodeB, relay base station.
Frequency configuration need to be carried out according to the Neighboring Cell List in its adjacent area in micro-base station.Because the adjacent area of micro-base station may exist one or morely, first micro-base station needs its adjacent area around to intercept, then to the carrier/interface ratio of the broadcast channel listening to meet certain threshold requirement adjacent area broadcast channel carry out system message parsing.
Micro-base station, after start powers on, is first modeled to mobile terminal by oneself, then identifies by characteristic signal the broadcast channel existing in wireless environment around, and broadcast channel instruction adjacent area exists, and records its corresponding dominant frequency point simultaneously and intercepts power.For example, for gsm system, characteristic signal represents frequency correction channel FCCH (Frequency Correction Channel) and synchronous channel SCH (Synchronization channel) subsequently thereof.For other system, also corresponding different characteristic signal, owing to being prior art herein, therefore no longer the characteristic signal of different system is repeated one by one.
In the time that micro-base station determines that the carrier/interface ratio of the broadcast channel of the adjacent area of having intercepted meets certain threshold requirement, the broadcast channel of this adjacent area is carried out system message parsing and records Neighboring Cell List, the size of threshold value is to be determined by the hardware of micro-base station, micro-base station can be carried out one by one system message for the BCCH frequency on the adjacent area of having intercepted and be resolved trial, for the adjacent area of successfully resolved, got off in this adjacent area and corresponding information recording thereof, information member's main information of having resolved comprises CI (Cell Identity, Cell Identity CI), LAC (Location Area Code, Location Area Code), PI (Cell Reselect Parameter Indication, cell reselection parameters instruction), RxlevAccMin (representing that community allows the minimal detectable power of mobile terminal access), CRO (Cell Reselect Offset, cell reselection offset amount), CRH (Cell Reselection Hysteresis, cell reselection lags behind), PT (Penalty Time, Penalty time), TO (Temporary Offset, interim biasing) and the information such as BA1 table.
The information that has resolved in conjunction with adjacent area micro-base station and cell reselection parameters thereof, determine that the BCCH frequency of the Neighboring Cell List of the adjacent area obtaining occurs simultaneously, and selects frequency to carry out the frequency configuration of micro-base station in BCCH frequency occurs simultaneously.The Neighboring Cell List of the adjacent area obtaining due to micro-base station may have multiple, obtains in order to improve the efficiency that BCCH frequency occurs simultaneously, and a part of adjacent area is selected from high to low by priority of adjacent domain in micro-base station, asks BCCH frequency to occur simultaneously to the Neighboring Cell List of the higher adjacent area of priority.
For example, micro-base station has obtained the Neighboring Cell List of 8 adjacent areas, selects 4 adjacent areas according to the priority of adjacent area, only determines that according to the Neighboring Cell List of 4 higher adjacent areas of priority BCCH frequency occurs simultaneously.Certainly the several adjacent areas of concrete selection can be adjusted arbitrarily.
Preferably, described micro-base station determines that according to the Neighboring Cell List of at least two adjacent areas that obtain the BCCH channel of broadcast control frequency of Neighboring Cell List occurs simultaneously, and comprising:
Described micro-base station judges whether the quantity of acquired Neighboring Cell List is less than N, if so, determines that according to the Neighboring Cell List of acquired all adjacent areas BCCH frequency occurs simultaneously;
Otherwise, determine that according to the Neighboring Cell List of N the highest adjacent area of priority BCCH frequency occurs simultaneously;
Wherein, N is greater than 2 positive integer.
Micro-base station is after having determined the Neighboring Cell List of the adjacent area obtaining, whether first determine in these Neighboring Cell List exists BCCH frequency to occur simultaneously, if existed, candidate's frequency that all frequencies configure as micro-base station frequency point in BCCH frequency occurs simultaneously, if now do not have BCCH frequency to occur simultaneously, so according to the priority of adjacent area, after being deleted, the Neighboring Cell List of adjacent area minimum priority judges again in remaining Neighboring Cell List whether exist BCCH frequency to occur simultaneously, if existed, candidate's frequency that all frequencies configure as micro-base station frequency point in BCCH frequency occurs simultaneously, otherwise deleting a minimum Neighboring Cell List of priority of adjacent domain judges again,
According to this determination methods, in the time that last two remaining Neighboring Cell List still do not have BCCH frequency to occur simultaneously,
The BCCH frequency that can determine the Neighboring Cell List of resolving the adjacent area obtaining occurs simultaneously for empty.
In order to describe in detail, the LAC that now supposes micro-base station is 200, there are A, B, C, D, E, six adjacent areas of F around in it, it is intercepted and resolving information is as shown in table 1, the adjacent area of having intercepted comprises A, B, C, D, E, six adjacent areas of F, the adjacent area of resolving comprises A, B, C, D totally four adjacent areas, specifically as shown in table 1:
Table 1
First sort the adjacent area of having resolved micro-base station by priority of adjacent domain.
Priority of adjacent domain is that the cell type of intercepting power and adjacent area by the BCCH frequency of the cell reselection priority value of adjacent area, adjacent area determines jointly, above-mentioned three parameters are adjustment order as required, or only carry out priority of adjacent domain sequence by partial parameters, the present invention does not limit.For WCDMA system and TD-SCDMA system, the cell reselection priority value of adjacent area is R value; For gsm system, the cell reselection priority value of adjacent area is C2 value.
Consider from the angle that is selected into that solves micro-base station,, under the identical condition of C2 value, pay the utmost attention to BCCH frequency and intercept the adjacent area that power is larger.For identical consideration, under equal conditions, preferentially select grand net adjacent area to configure with reference to adjacent area as dominant frequency point in addition.
The cell type of adjacent area can be divided into: homologous ray community, different system cell, and homologous ray community can be divided into Hong Wang community, micro-base station cell, and different system cell can be divided into Hong Wang community, micro-base station cell; Adjacent area is according to priority homologous ray community, the sequence of different system cell; Homologous ray community is according to priority Wei Hongwang community, the sequence of micro-base station cell again; Different system cell is according to priority Wei Hongwang community, the sequence of micro-base station cell again.
In gsm system, taking table 1 as example, the C2 value of each adjacent area is:
C2(A)＝-55dBm-(-90dBm)+10dB＝45dB；
C2(B)＝-65dBm-(-90dBm)+30dB＝55dB；
C2(C)＝-75dBm-(-90dBm)+30dB＝45dB；
C2(D)＝-85dBm-(-90dBm)+30dB＝45dB。
Therefore pressing the adjacent area order of C2 value sequence is B, A/C/D.It is large that the BCCH frequency of intercepting power ratio adjacent area C and D due to the BCCH frequency of adjacent area A is intercepted power, and therefore the priority of A is relatively high; In addition, under equal conditions, C Shi Hongwang community, adjacent area, and adjacent area D is Home eNodeB, therefore the cell reselection priority of C is relatively high, therefore final cell reselection priority is B, A, C, D.
Preferably, the priority of described adjacent area comprises:
The cell reselection priority value of adjacent area is the first priority, and the cell reselection priority value of adjacent area is larger, and the priority of described adjacent area is higher;
It is the second priority that the BCCH frequency of adjacent area is intercepted power, and when the cell reselection priority value of adjacent area equates, it is larger that adjacent area BCCH frequency is intercepted power, and the priority of described adjacent area is higher;
The cell type of adjacent area is the 3rd priority, adjacent area BCCH frequency intercept power equate time, the priority of grand net adjacent area is the highest.
Because differ and established a capital common factor in the Neighboring Cell List that micro-base station obtains, whether therefore micro-base station need to judge in the Neighboring Cell List of acquisition has BCCH frequency to occur simultaneously.
When the BCCH frequency that micro-base station obtains from the Neighboring Cell List of multiple adjacent areas occurs simultaneously for sky, the BCCH frequency that will redefine Neighboring Cell List occurs simultaneously, and determines that the method that BCCH frequency occurs simultaneously is by deleting after Neighboring Cell List herein, again determines BCCH frequency common factor.Concrete steps are as follows: the first step, delete the Neighboring Cell List of the adjacent area that priority is minimum; Second step, how many Neighboring Cell List are now also left in judgement, in the time that the quantity of remaining Neighboring Cell List exceedes 1, forward the 3rd step to, otherwise determine that BCCH frequency occurs simultaneously for empty; The 3rd step, judges whether remaining Neighboring Cell List has BCCH frequency to occur simultaneously, if had, determines BCCH frequency and occurs simultaneously, otherwise get back to the first step.
Taking table 1 as example, be totally 4 of A, B, C, D in the adjacent area of having resolved, continue to judge whether adjacent area A, B, C, D have BCCH frequency to occur simultaneously.
Now, A ∩ B ∩ C ∩ D=Φ, Φ represents to occur simultaneously for empty set, and the Neighboring Cell List of adjacent area A, B, C, D does not have BCCH frequency to occur simultaneously;
Now, delete the minimum adjacent area D of priority, adjacent area number becomes 3, continues to judge whether the Neighboring Cell List of adjacent area A, B, C has BCCH frequency to occur simultaneously;
Now, A ∩ B ∩ C=Φ, adjacent area A, B, C do not have BCCH frequency to occur simultaneously;
Now, delete the minimum adjacent area C of priority, adjacent area number becomes 2;
Continue to judge whether the Neighboring Cell List of adjacent area A and B has BCCH frequency to occur simultaneously:
A∩B＝{530，63}。Now adjacent area A and B have BCCH frequency to occur simultaneously.
Preferably, described definite BCCH frequency occurs simultaneously, and comprising:
Whether step 1, have BCCH frequency to occur simultaneously at least two Neighboring Cell List of described micro-base station judgement, if had, determine BCCH frequency and occur simultaneously, otherwise execution step two;
Step 2, according to the priority of adjacent area corresponding to Neighboring Cell List, judges whether the quantity of remaining Neighboring Cell List is greater than 1, if be greater than 1, turns back to step 1 after the Neighboring Cell List of adjacent area minimum priority is deleted, otherwise execution step three;
Step 3, determines BCCH frequency and occurs simultaneously for empty.
Micro-base station is being determined after BCCH frequency occurs simultaneously and can in BCCH frequency occurs simultaneously, selected at random the BCCH frequency of a BCCH frequency as affiliated subdistrict, micro-base station.In order to make the operating efficiency of system higher, now need in BCCH frequency occurs simultaneously, select to meet the BCCH frequency that BCCH frequency that certain communication quality requires is configured to affiliated subdistrict, micro-base station, the frequency condition that meets communication quality requirement is: intercept that level is less than interference threshold and working frequency range meets the BCCH frequency that micro-base station requires.
In gsm system, for being present in the Neighboring Cell List of adjacent area but the frequency of not intercepted by micro-base station, it is intercepted power and is defaulted as minimum, agreement regulation-110dBm.Working frequency range meets micro-base station and requires to refer to micro-base station and be limited to the workable frequency point ranges of hardware, and for example in the present embodiment, micro-base station can only work in 1800MHz.The minimum that interference threshold can be made as Yu Zhe community allows access power to add certain correction value, or co-channel interference principle is definite, and the present invention does not limit.
Taking table 1 as example, in the embodiment of the present invention, establishing interference threshold value is-90dBm that the working frequency range of micro-base station is 1800MHz frequency range, determine A ∩ B={530,63}, because the power of intercepting of BCCH frequency 530 is-75dBm, obviously be greater than interference threshold value-90dBm, therefore got rid of; Because BCCH frequency 63 belongs to 900MHz frequency range, do not belong to the working frequency range category of this micro-base station simultaneously, got rid of yet.
What micro-base station obtained from the Neighboring Cell List of multiple adjacent areas is not to contain at least one BCCH frequency during empty BCCH frequency occurs simultaneously, but these BCCH frequencies can not meet the communication quality requirement of micro-base station sometimes, the BCCH frequency that at this moment will redefine Neighboring Cell List occurs simultaneously, redefine method and above similar that BCCH frequency occurs simultaneously herein, again determine BCCH frequency common factor by the method for deleting Neighboring Cell List.Concrete steps are as follows: the first step, delete the Neighboring Cell List of the adjacent area that priority is minimum; Second step, how many Neighboring Cell List are now also left in judgement, in the time that the quantity of remaining Neighboring Cell List exceedes 1, forward the 3rd step to, otherwise determine that BCCH frequency occurs simultaneously for empty; The 3rd step judges whether to meet the BCCH frequency that the communication quality of micro-base station requires in the BCCH frequency of trying to achieve occurs simultaneously, if had, determines all BCCH frequencies that satisfy condition, otherwise gets back to the first step.
Taking table 1 as example, by above analysis, in fact A ∩ B=Φ.Delete the low adjacent area A of priority, so the configuration of dominant frequency point can only be adjacent area B with reference to adjacent area.The BA1 table of last adjacent area B comprises that { 530,730,53,63}, excludes the BCCH frequency 530 that interference threshold is greater than interference threshold value-90dBm; Remove the BCCH frequency 53,63 that does not meet working frequency range requirement; Remaining BCCH frequency 730, the BCCH frequency of Gu Jiangzhe community is configured to 730.
If adjacent area A, B, C exist BCCH frequency to occur simultaneously in table 1, and when BCCH frequency does not meet the BCCH frequency of communication quality requirement in occuring simultaneously, now can leave out the Neighboring Cell List of the adjacent area that priority is minimum, during the BCCH frequency that rejudges remaining Neighboring Cell List occurs simultaneously, whether have and meet the BCCH frequency that communication quality requires.If do not meet the BCCH frequency that communication quality requires during last only surplus two adjacent areas that priority is the highest and BCCH frequency occur simultaneously, determine that BCCH frequency occurs simultaneously for empty.
Preferably, described micro-base station selects one to intercept that level is less than interference threshold and working frequency range meets the BCCH frequency that described micro-base station requires in described BCCH frequency occurs simultaneously, and before the BCCH frequency as affiliated subdistrict, described micro-base station, comprising:
Step 1, described micro-base station judges whether in described BCCH frequency occurs simultaneously to intercept that level is less than interference threshold and working frequency range meets the BCCH frequency that described micro-base station requires, if had, determine all BCCH frequencies that satisfy condition, otherwise execution step two;
Step 2, according to the priority of adjacent area corresponding to Neighboring Cell List, after being deleted, the Neighboring Cell List of adjacent area minimum priority judges whether the quantity of remaining Neighboring Cell List is greater than 1, if be greater than 1, redefine out BCCH frequency and occur simultaneously and turn back to step 1, otherwise execution step three;
Step 3, determines BCCH frequency and occurs simultaneously for empty.
By description above, micro-base station determines that BCCH frequency occurs simultaneously for having two kinds of situations in vain: the first is in the Neighboring Cell List of the adjacent area obtaining, not have BCCH frequency to occur simultaneously; Although the second is to have BCCH frequency to occur simultaneously in the Neighboring Cell List of adjacent area obtaining, BCCH frequency not have in occuring simultaneously to meet intercepts the BCCH frequency that level is less than interference threshold and working frequency range and meets the requirement of micro-base station.The processing mode of both of these case is the same, and to be exactly micro-base station occur simultaneously for after sky at definite BCCH frequency for that, selects the BCCH frequency of BCCH frequency as affiliated subdistrict, micro-base station in the Neighboring Cell List of the highest adjacent area of priority corresponding to Neighboring Cell List.
Taking table 1 as example, after A ∩ B is sky, the reference adjacent area of micro-base station frequency point configuration can only be adjacent area B.BA1 table in the Neighboring Cell List of adjacent area B comprises { 530,730,53,63}, except not meeting the frequency 530 of interference requirement and not meeting the frequency 53 and 63 that micro-base station working frequency range requires, only remaining frequency 730, therefore be configured to frequency 730 by the frequency of micro-base station cell.
Although adjacent area A intercepts level maximum, because the C2 value of adjacent area B is the highest, micro-base station mobile terminal around resides in the maximum probability of B community, also when B as frequency configuration with reference to Shi Wei base station, adjacent area to be selected into probability higher.
Preferably, described in determine BCCH frequency and occur simultaneously for after sky, comprising:
The highest adjacent area of priority that selection Neighboring Cell List is corresponding configures the reference adjacent area of BCCH frequency as described micro-base station;
Select to intercept level in reference to the Neighboring Cell List of adjacent area and be less than interference threshold and working frequency range and meet BCCH frequency that described micro-base station the requires BCCH frequency as affiliated subdistrict, described micro-base station described.
While having multiple BCCH frequencies to meet in BCCH frequency occurs simultaneously to intercept level to be less than interference threshold and working frequency range to meet described micro-base station and require, micro-base station is random, and to select a BCCH frequency be that oneself configures frequency.
