Embodiment
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope of protection of the invention.
In empty offshoot program of the present invention, comprise based on the empty offshoot program of cell portion with based on the empty offshoot program of terminal.Wherein, RNC need to be according to terminal the ownership of the RSCP in each cell potion (ReceivedSignal Code Power, received signal code power) judgement terminal.So, in the clear and definite embodiment of the present invention based on the empty offshoot program of cell portion, below at first the ownership of the RNC judgement of the RSCP in each cell portion terminal according to terminal is introduced.
In existing cell portion characteristic, the base station can report the RSCP of each terminal on a plurality of cell portion (a corresponding RSCP of cell portion and report number to be configured by RNC), and the RSCP information of each cell portion of terminal that RNC reports according to the base station judges the ownership of terminal.When the RSCP number that reports during more than one, cell portion corresponding to maximum RSCP is the best ownership of terminal, if the RSCP that other cell portion are corresponding and the difference of maximum RSCP surpass specified thresholds, terminal does not belong to this cell portion, otherwise belongs to simultaneously this cell portion.When the RSCP number that reports only was one, the cell portion that this RSCP is corresponding was the best ownership of this terminal.
Such as in the cell of the signal that receives terminal a portion, maximum RSCP is the RSCP_i_a that belongs to cellportion i, and another RSCP is the RSCP_j_a that belongs to cell portion j.When RSCP_i_a-RSCP_j_a＜P_threshholdl (specified thresholds), terminal a belongs to cellportion i and j simultaneously, and wherein cell portion i is the cell portion of the best ownership of terminal; Otherwise terminal a only belongs to cell portion i.When the RSCP that reports only was a RSCP_i_a, cell portion i was the best ownership of this terminal.
As shown in Figure 1, the air separating method for a kind of DPCH in embodiments of the invention specifically comprises the following steps:
The RSCP of the different terminals of step 101, reception base station transmission;
Step 102, obtain empty minute isolation according to described RSCP;
Step 103, divide isolation to judge between described different terminals according to described sky whether to satisfy default sky minute condition; The terminal that satisfies described default sky minute condition is carried out sky minute.
Below describe take network equipment as RNC as example, but be not limited to this, everyly can carry out the DPCH equipment of empty minute at network side and all belong to protection scope of the present invention.
As shown in Figure 2, be the DPCH air separating method in embodiments of the invention, its hollow offshoot program specifically comprises the following steps for the sky based on cell portion divides:
Wherein, RSCP is that different terminals is at one time based on the RSCP of cell portion.
The base station reports the RSCP based on cell portion to comprise any in following two kinds of situations:
(a) base station only reports each terminal at the RSCP of a cell portion.
For example: the base station report two terminal a, b respectively in cell portion i, j corresponding RSCP be RSCP_i_a and RSCP_j_b.
(b) base station reports each terminal respectively at the RSCP of at least two cell portion.
For example: the base station report two terminal a, b respectively in cell portion i, j corresponding RSCP be RSCP_i_a, RSCP_j_a, RSCP_i_b, RSCP_j_b.
Particularly, RNC judges that according to the RSCP that receives the ownership of terminal comprises any in following two kinds of situations:
(a) base station only reports each terminal at the RSCP of a cell portion.
When the RSCP of the same terminal that reports number only was one, RNC judged that cell portion corresponding to this RSCP is the best ownership of this terminal.
For example: RNC judgement this moment terminal a belongs to cell portion i; Terminal b belongs to cell portionj.
(b) base station reports each terminal at the RSCP of at least two cell portion.
When the RSCP of the same terminal that reports number during more than one, cell portion corresponding to the RNC maximum RSCP of judgement is the best ownership of this terminal, if the RSCP that other cell portion are corresponding and the difference of maximum RSCP surpass specified thresholds, this terminal does not belong to this cell portion, otherwise this terminal belongs to this cell portion simultaneously.
Belong to cell portion i with RNC judgement terminal a in the embodiment of the present invention; It is that example describes that terminal b belongs to cell portion j.
The sky that step 203, RNC obtain between corresponding cell portion according to the ownership of terminal divides isolation.
Preferably, the sky between cell portion divides isolation to embody with the form of form.
A belongs to cell portion i when RNC judgement terminal, and when terminal b belonged to cell portionj, RNC divided the sky that obtains between cell portion i and cell portion j isolation kilsyth basalt lattice to divide isolation Lij from sky.Wherein, Lij is the sky minute statistic that belongs to all terminals of cell portion i and belong to the RSCP difference power of same time measurement between all terminals of cell portion j, such as: belong to all terminals of cell portion i and belong to minimum value, average, smooth value or the sliding window statistical average etc. of the RSCP difference power of same time measurement between all terminals of cell portion j, can be configured by RNC.
Need to prove, generally can think Lij=Lji (i ≠ j), Lii=0 (terminal under same cellportion can not empty minute).In addition, obtaining different skies minute statistic by RSCP can control terminal between different cell portion and can carry out the pairing degree of empty minute.For example: during the minimum value of the RSCP difference power of measuring between cell portion i and cell portion j for all terminals as Lij, if Lij satisfies empty minute condition, guaranteed that between two cell portion, nearest terminal also can satisfy empty minute, have relatively high expectations but this space-time divides, it is lower that terminal can be carried out the pairing degree of empty minute; During the average of the RSCP difference power of measuring between cell portion i and cell portion j for all terminals as Lij, if Lij satisfies empty minute condition, this space-time divides and has relatively high expectations, it is lower that terminal can be carried out the pairing degree of empty minute, but disturb for existing between a part of terminal (in the terminal of the RSCP difference power of measuring between cell portion i and cell portion j less than this average).
In empty offshoot program based on cell portion, need to safeguard that the sky between cell portion divides isolation kilsyth basalt lattice, the method that this form produces has following two kinds:
(a) obtain empty minute isolation kilsyth basalt lattice in the base station
The base station is according to the RSCP of all terminals between cell portion i and cell portionj that measures, obtain the sky minute statistic of all terminals between cell portion i and cell portion j of measurement, the sky that is cell portion i and cell portion j divides isolation Lij, and it is added into the empty minute relevant position in isolation kilsyth basalt lattice.
The base station divides state table to upgrade according to existing end message to sky at interval of T1 time (T1 is configurable); Every T2 time (T2 is configurable), perhaps report (for example: RNC reports request, and perhaps the sky of base station maintenance reports after dividing isolation kilsyth basalt lattice to occur upgrading) by Event triggered, empty minute isolation kilsyth basalt lattice of the cell portion that upgrades are reported RNC.
(b) obtain empty minute isolation kilsyth basalt lattice at RNC
The method that obtains empty minute isolation kilsyth basalt is consistent with the base station end, is all to obtain according to the RSCP that measures, and be only that empty minute isolation kilsyth basalt lattice are obtained by RNC oneself this moment, and do not need the base station to report.
Need to prove, because RNC can report the number Number OfReported Cell Portions of RSCP by configurating base station, so the number that the requirement that requires RNC to configure to the base station reports RSCP is divided isolation greater than 1 otherwise RNC can't judge sky.As shown in table 1, for the sky of different cell portion divides isolation:
The sky of table 1, different cell portion divides isolation
| Port1 | Port2 | Port3 | Portn | |
| Port1 | L11 | L12 | L13 | L1n |
| Port2 | L21 | L22 | L23 | L2n |
| Port3 | L31 | L32 | L33 | L3n |
| Portn | Ln1 | Ln2 | Ln3 | Lnn |
Isolation kilsyth basalt lattice obtained by long-time statistical and revised in empty minute, when in certain period, number of terminals is fewer impact smaller, can think form or available.
Need to prove; isolation kilsyth basalt lattice were preferred embodiment a kind of in the embodiment of the present invention in empty minute; everyly can provide the sky between different cell portion to divide the method for isolation all to belong to protection scope of the present invention, such as: embody in modes such as corresponding relation, character express.
RNC sets in advance empty minute isolation thresholding M, and the sky that RNC will obtain divides isolation Lij and the sky of presetting to divide isolation thresholding M to compare:
When Lij＞M, RNC judgement cell portion i and cell portion j satisfy empty minute condition, and the terminal that judgement belongs to cell portion i and cell portionj can be carried out sky at DPCH and divided, and forwards step 205 to;
When Lij≤M, RNC judgement cell portion i and cell portion j do not satisfy empty minute condition, and the terminal that judgement belongs to cell portion i and cell portionj cannot be carried out sky at DPCH and be divided.
For example: the terminal of initial access and the sky of other-end divide statistic to satisfy empty minute condition, can carry out sky and divide; After after a while, the sky of this terminal and other-end divides statistic not satisfy empty minute condition, cannot carry out the sky timesharing, need to readjust the resource of terminal.
preferably, in the situation that resource is inadequate or without available resources, in order to guarantee DPCH terminal call drop not in the resource adjustment process, the priority of each business is set: CS business＞PS business＞H business, CS (Circuit Switch wherein, circuit switching) business is speech business, PS (Packet Switching, packet switching) business is stream class service, the H business is HSDPA (High SDeed Downlink PacketAccess, high speed downlink packet accesses) or HSUPA (High Speed Uplink Packet Access, the High Speed Uplink Packet access) business.Below for carry out the scheme that resource is adjusted according to priority:
(1) if the sky between the CS terminal divides, need the enough resources of advance reservation, if resource is inadequate, can directly seize the H resource;
(2) if the sky between CS terminal and PS terminal divides, perhaps the sky between the PS terminal divides, if there is the H resource, DPCH can seize the H resource; If do not have the H resource to seize, can adopt reduction of speed to process to the PS terminal.
Need to prove, for the empty offshoot program based on cell portion clearly is described, in the embodiment of the present invention, the cell portion of terminal attaching describes as an example of a cell portion example.During more than a cell portion, need the cellportion of this each ownership of terminal and the cell portion of other-end ownership all to satisfy above-mentioned sky minute condition as the cell portion of the ownership of terminal.For example: the cell portion of terminal a ownership is cell portion i and cell portion m, the cell portion of terminal b ownership is cell portion j, need cell portion i and cell portion j, when cell portion m and cell portionj satisfy above-mentioned sky minute condition simultaneously, could judge that terminal a and terminal b can empty minutes.And the sky that above-mentioned this scheme can be generalized in the middle of a plurality of terminals divides judgement.
According to the upper terminal determination methods that belongs to and the determination methods that meets empty minute condition as can be known, for the terminal of empty minute, if variation (even if the best ownership does not have to change) has occured the cell portion of terminal attaching, also need to rejudge this terminal and whether can also divide with other-end is empty.If do not satisfy empty minute condition, need to adjust the resource of terminal, terminal is switched on other resources.Wherein, the resource of adjustment terminal comprises with empty minute of other-end, takies idling-resource, seizes other H resources etc.
As shown in Figure 3, be the DPCH air separating method in embodiments of the invention, its hollow offshoot program specifically comprises the following steps for the sky based on terminal divides:
The base station reports each terminal respectively at the RSCP of at least two cell portion.Through repeatedly receiving, RNC has each terminal at the RSCP based on cell portion of different time.
For example: the base station report two terminal a, b respectively in Cell portion i, j corresponding RSCP be RSCP_i_a, RSCP_j_a, RSCP_i_b, RSCP_j_b.
When the judgement counterpart terminal satisfies empty minute condition, forward step 303 to; Otherwise, terminal is not carried out sky and divides.
Based on the empty offshoot program of terminal, the RSCP that RNC receives need meet the following conditions simultaneously:
(a) same terminal is divided the isolation thresholding at the satisfied default sky of the difference of the RSCP of different cell portion;
(b) each terminal is divided the isolation thresholding at RSCP and the other-end of the cell of its ownership portion at the satisfied default sky of the difference of the RSCP of this cellportion.
For example: when two terminal a, b belong to respectively cell portion i, j, when corresponding RSCP is RSCP_i_a, RSCP_j_a, RSCP_i_b, RSCP_j_b, require to meet the following conditions simultaneously between each RSCP value:
(a)RSCP_i_a-RSCP_i_b＞M；RSCP_j_b-RSCP_j_a＞M；
(b)RSCP_i_a-RSCP_j_a＞M；RSCP_i_b-RSCP_j_b＞M；
Wherein M divides the isolation thresholding for default sky.At this moment, terminal a, b can emptyly divide.
Need to prove, above-mentioned is to judge by the difference that judges different RSCP and the sky relation between isolation of dividing of presetting, can certainly be the statistic of the difference of different RSCP, such as: same terminal is got average, smooth value or sliding window statistical average etc. in the different RSCP differences of different time gained.
In addition, when unnecessary one of the cell of terminal attaching portion, need to carry out for the cell portion of this each ownership of terminal above-mentioned judgement flow process.For example: when the cell portion of terminal a ownership is cellportion i and cell portion m, when the cell portion of terminal b ownership is cell portion j, after carrying out above-mentioned judgement for the ownership cell portion i of terminal a, also need to carry out above-mentioned judgement for the ownership cellportion m of terminal a, particularly, need to meet the following conditions simultaneously between each RSCP value:
(c)RSCP_m_a-RSCP_m_b＞M；RSCP_j_b-RSCP_j_a＞M；
(d)RSCP_m_a-RSCP_j_a＞M；RSCP_m_b-RSCP_j_b＞M；
Wherein M divides the isolation thresholding for default sky.At this moment, when each RSCP value of terminal a, b satisfies above-mentioned (a), (b), (c) and (d) time simultaneously, judgement terminal a, b can empty minutes.And the sky that above-mentioned this scheme can be generalized in the middle of a plurality of terminals divides judgement.
Being satisfied the process of empty minute condition can find out by above-mentioned judgement terminal, empty offshoot program based on terminal can judge whether satisfy empty minute condition between terminal more accurately, but need RNC to safeguard the information of each terminal, and to carrying out sky minute judgement between all terminals, data volume is larger, disposal ability requirement to RNC is higher, and complexity is higher.
For example: the terminal of initial access and the sky of other-end divide statistic to satisfy empty minute condition, can carry out sky and divide; After after a while, the sky of this terminal and other-end divides statistic not satisfy empty minute condition, cannot carry out the sky timesharing, need to readjust the resource of terminal.
Preferably, in the situation that resource is inadequate or without available resources, in order to guarantee DPCH terminal call drop not in the resource adjustment process, the priority of each business is set: CS business＞PS business＞H business, below for carry out the scheme that resource is adjusted according to priority:
(1) if the sky between the CS terminal divides, need the enough resources of advance reservation, if resource is inadequate, can directly seize the H resource;
(2) if the sky between CS terminal and PS terminal divides, perhaps the sky between the PS terminal divides, if there is the H resource, DPCH can seize the H resource; If do not have the H resource to seize, can adopt reduction of speed to process to the PS terminal.
