Description
Technical field
The present invention relates to moving communicating field, more particularly to a kind of Physical Cell Identifier (Physical cell ID, PCI)
Distribution method, system and eNB, webmaster.
Background technology
LTE network only has 504 PCI codes can use, and a commercial network is made up of thousands of individual eNB, and each eNB is again
It is divided into several cells, it is clear that PCI codes can be reused.The mobility brought to avoid PCI codes from being reused is obscured,
The basic principle of PCI planning is to ensure that one layer adjacent and two layers of neighbor cell are reused without PCI, i.e. PCI distribution need to be kept away
Exempt from following two situations to occur.
1) one layer of neighbor cell uses identical PCI, i.e., two PCI identical cells in a cell coverage area be present
Signal.
2) two layers of neighbor cell use identical PCI, i.e. two PCI identicals adjacent areas be present under an eNB.
In order to further reduce operator cost, efficiency of operation is improved, neighbour is introduced in 3GPPR8 stage SON functions
The automatic settlement mechanism of cell PCI conflicts, it finds that the approach of PCI conflicts is generally：UE is reported, is reported and sent out by adjacent area X2 interface
Now conflict or obtain by other means (such as HeNB has found peripheral cell PCI by downlink receiver).Once conflict,
Reported by network elements is notified to network management system, and the calculating and configuration of PCI optimizations are arranged by network management system center.
As can be seen that the PCI Automatic Optimals scheme in existing standard can solve the main bar of two neighbor cell PCI conflicts
Part is that two adjacent cells have been made into neighbors relation, still, possesses identical PCI for two neighbor cells, but this two
Individual cell is not made into the scene of neighbors relation (i.e. leakage conflict districts), above-mentioned SON PCI contention-resolution schemes then without
Method is applicable, so as to influence the stability of a system.
The content of the invention
In view of this, can it is a primary object of the present invention to provide a kind of PCI distribution method, system and eNB, webmaster

The PCI of each cell in adjacent eNB address and each adjacent eNB；
In the present embodiment, webmaster stores each eNB adjacent eNB information.
Step 202：The eNB judges that the eNB is identical with whether there is in adjacent eNB according to the adjacent eNB information
PCI, if it is decided that identical PCI be present in the eNB and adjacent eNB, then notify corresponding adjacent eNB to re-start PCI
Distribution, so that the eNB in the adjacent eNB with being not present identical PCI.
Optionally, eNB described in step 202 notifies adjacent eNB to re-start PCI and be assigned as：
The eNB selects a PCI, and the PCI is sent into the adjacent eNB, the PCI and eNB and described
PCI in adjacent eNB is differed；So that the PCI for producing conflict is revised as the PCI of the eNB transmissions by the adjacent eNB.
Optionally, eNB described in step 202 notifies adjacent eNB to re-start PCI and be assigned as：
PCI in the eNB and eNB other adjacent eNBs is sent to the adjacent eNB by the eNB, so that institute
State adjacent eNB and select the PCI different from the PCI in the eNB and eNB other adjacent eNBs, and conflict will be produced
PCI is revised as the PCI of the selection.
Fig. 3 is another kind PCI distribution method detailed process schematic diagram of the embodiment of the present invention, as shown in figure 3, this method is specific
Including：
Step 301：Webmaster judges to whether there is identical PCI in center eNB and non-central eNB.
In the present embodiment, webmaster storage eNB groups, the eNB groups include a center eNB, other in the eNB groups
ENB is adjacent with the center eNB.
Step 302：If it is determined that identical be present in the eNB of center in a non-central eNB and the eNB groups in eNB groups
PCI, then the PCI of conflict is produced in the webmaster modification non-central eNB, so that in the non-central eNB and center eNB not
Identical PCI be present, afterwards, PCI modifications situation is notified to corresponding eNB.
The embodiment of the present invention also correspondingly proposes a kind of PCI distribution systems, as shown in figure 4, the system includes：First

Embodiment 1
Figure 10 is the distribution situation schematic diagram of base station in the embodiment of the present invention 1, in the present embodiment, pre-defines each eNB
Cell PCI set, if the PCI of eNB1 three cells is PCI11, PCI12 and PCI13 definition sets eNB1=
{ PCI11, PCI12, PCI13 }.If two adjacent eNBs have the overlapping covering of identical, i.e. the two eNB have adjacent neighbors pass
System, if eNB1 and eNB2 is adjacent eNB, in addition, to each eNB, webmaster collects all adjacent eNBs, e.g., eNB1 adjacent eNB
It is eNB2 and eNB3.
Figure 11 is the PCI distribution method schematic flow sheet described in the embodiment of the present invention 1, and as shown in figure 11, the flow includes：
Step 1101：Webmaster issues eNB adjacent eNB information to each eNB.
Here, adjacent eNB information includes eNB address, the PCI of eNB each cell.
Step 1102：For each eNB, eNB PCI phases the PCI of eNB all cells with adjacent eNB one to one
Than.
Here, cell PCI is typically exchanged by X2 interface between neighbor cell.
Step 1103：If some cells of two adjacent eNBs possess same PCI, such as eNB1 ∩ eNB2 ≠ { }.
Step 1104：To eNB2 instructions cell PCI conflicts may occur for eNB1, and eNB1 is optional to eNB2 recommendations one
PCI scope, or specify a PCI.
In this step, eNB1 can select one and the eNB1 cell PCI and cell PCI of other eNB1 adjacent eNBs not phases
Same PCI is sent to eNB2, the cell PCI of oneself (eNB1) and the cell PCI of other eNB1 adjacent eNBs can also can be sent out
To eNB2, the PCI different from the PCI values received is selected by eNB2.
Step 1105：ENB2 changes related cell PCI according to the eNB1 optional scopes of PCI recommended or PCI.
Step 1106：ENB1 and eNB2 exchanges PCI and confirms new PCI values.
Embodiment 2
In the present embodiment, adjacent several eNB are organized into eNB groups by network management center's formula, and ensure that each eNB groups have
One center eNB, i.e., an eNB and all eNB always be present in each group is neighbouring relations.With reference to figure 10, eNB1 is such as schemed,
ENB2 and eNB3 composition eNB groups, eNB1 is center eNB.
The present embodiment flow includes：
Webmaster one by one compares the center eNB of each eNB groups PCI and other eNB PCI；
When some eNB PCI is identical with center eNB PCI, then webmaster changes PCI and the lower eNB to correlation.
For example webmaster compares eNB1 and eNB2 PCI, when eNB2 and eNB1 possesses identical PCI, webmaster changes eNB2's
PCI, and the eNB2 issued.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.

PCI different PCI in eNB other adjacent eNBs；
The PCI configuration modules, if for identical PCI in adjacent eNB be present, will produce what is conflicted with adjacent eNB
PCI is revised as the PCI of the selecting module selection, so that the eNB in the adjacent eNB with being not present identical PCI.
13. a kind of webmaster, it is characterised in that the webmaster includes：Memory module and sending module；Wherein,
The memory module, for storing each eNB adjacent eNB information；The adjacent eNB information includes：The ground of adjacent eNB
The PCI of each cell in location and each adjacent eNB；
The sending module, for the adjacent eNB information stored according to memory module, send corresponding adjacent eNB to each eNB and believe
Breath, if so that the eNB judges to notify corresponding adjacent eNB again to enter with identical PCI, the eNB in adjacent eNB be present
Row PCI is distributed so that identical PCI is not present in each eNB eNB adjacent thereto.
14. a kind of webmaster, it is characterised in that the webmaster includes：Memory module, judge module, PCI configuration modules and transmission mould
Block；Wherein,
The memory module, for storing eNB groups, the eNB groups include a center eNB, non-central in the eNB groups
ENB is adjacent with the center eNB；
The judge module, for judging to whether there is identical in the eNB of center in non-central eNB and the eNB groups in eNB groups
PCI；
The PCI configuration modules, for judging identical be present in a non-central eNB and center eNB in eNB groups in judge module
During PCI, the PCI that conflict is produced in the non-central eNB is changed, so that the non-central eNB in the center eNB with being not present
Identical PCI；
The sending module, for PCI modifications situation to be notified to corresponding eNB.
