Existing cell mobile communication systems, for example: 3-G (Generation Three mobile communication system), the data rate that provides has very big difference at center of housing estate and cell edge, has not only influenced the capacity of whole system, and the service quality that the user is obtained in different positions has very big fluctuation.Presence of intercell interference (Inter-cellInterference, hereinafter to be referred as: ICI) be an intrinsic problem of cell mobile communication systems, traditional solution is to adopt channeling, and multiplexing coefficient has only specific several selections, as 1,3,7 etc.Multiplexing coefficient is 1 to represent that promptly neighbor cell all uses identical frequency resource, at this moment disturbs very serious at cell edge.Higher multiplexing coefficient, for example: 3 or 7, can suppress ICI effectively, but spectrum efficiency will be reduced to 1/3 or 1/7.For improving the availability of frequency spectrum of Radio Resource, under the normal condition, the frequency duplex factor as one in the system is 1, can use all frequency bands to transmit data to guarantee each sub-district.In this case, particularly for Cell Edge User, presence of intercell interference becomes the principal element that influences the future communications systematic function.If two neighbor cells use identical frequency spectrum resource in their joint portion, then can produce stronger ICI.
The ICI inhibition technology of studying at present mainly comprises interference randomization, interference coordination, interference eliminated etc.Interference randomization can not reduce the energy of interference, but can be " white noise " with interference randomization, thereby suppresses the harm of ICI, therefore is called again " interference whitening ".Interference coordination comprises " soft-frequency reuse " and " partial frequency multiplexing ", and this method is distinguished the user at center of housing estate and edge, distributes different frequency resource and power resource.Interference cancellation techniques derives from multiuser detection, can be with signal demodulation, the decoding of interfered cell, and will duplicate from the ICI of this sub-district then and deduct.Interference eliminated to the frequency resource of cell edge without limits, can realize the cell edge spectrum efficiency be 1 and total frequency spectrum efficient be 1.Other technology, for example MIMO, smart antenna, part power control etc. also can be used for ICI and suppress.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: because Long Term Evolution advanced person (Long Term Evalution_advance, hereinafter to be referred as: LTE_A) system has introduced via node, make the ICI problem become complicated more, not only there is the interference between the via node and via node between the sub-district, via node and subscriber equipment (User Equipment, hereinafter to be referred as: the interference UE), also there are the UE of via node service and the interference between the UE, and, do not solve the scheme of the ICI problem in the LTE_A system with via node in the prior art because the information interaction of via node and other network node must just can be finished through its current service cell.

Automatically dispose method second embodiment of the Serving cell of via node
As shown in Figure 2, automatically dispose the flow chart of method second embodiment of the Serving cell of via node for the present invention, on the basis of technical scheme shown in Figure 1, the edge via node is the select target sub-district under the triggering of current service cell, can also comprise the steps: before the step 11
Step 20, edge via node receive the gravity treatment Indication message that current service cell sends.
Wherein, the gravity treatment Indication message of edge via node reception current service cell transmission specifically can comprise following two kinds of situations:
When 1) current service cell need be carried out Inter-Cell Interference Coordination, the edge via node needed the new Serving cell of gravity treatment, thereby reduces this interference, so current service cell sends the gravity treatment Indication message to the edge via node.
When 2) neighbor cell of current service cell was opened or is waken up, because variation has taken place wireless environment, whether the edge via node continued to provide service by current service cell, needed to coordinate again.Therefore, current service cell receives the unlatching Indication message that its neighbor cell sends earlier, current service cell knows that according to this unlatching Indication message its neighbor cell opens or be waken up then, so send the gravity treatment Indication message to the edge via node, comprise the information that neighbor cell is opened in this gravity treatment Indication message.
For the select target sub-district, on the basis of technical scheme shown in Figure 1, step 11 specifically can comprise the steps:
Whether step 21, edge relay node judges current service cell are the initial service sub-district.If current service cell is the initial service sub-district, execution in step 22; If current service cell is not the initial service sub-district, execution in step 23.
Wherein, the initial service sub-district is an operator when laying the edge via node, the sub-district that the edge via node is belonged to.
Step 22, edge via node are according to the measurement result of the UE of itself and/or its service, select target sub-district, execution in step 24.
Wherein, one or more in the interference that is subjected to of the edge via node measured of the UE of the interference that is subjected to the link of edge via node of the measurement result of the UE of edge via node and/or the edge via node service UE that specifically can comprise the received signal quality of the neighbor cell of current service cell that the edge via node is measured according to the UE of itself and/or its service and current service cell, edge via node service that the edge via node is measured and edge via node service to the link of this UE.
If the neighbor cell of current service cell has one, then trunk node selection this neighbor cell in edge is as Target cell; If it is a plurality of that the neighbor cell of current service cell has, the edge via node as candidate target cells, according to this measurement result, selects a sub-district as Target cell from candidate target cells these a plurality of neighbor cells.At this moment, on the basis of technical scheme shown in Figure 1, the edge via node can also comprise Target Cell Identifier in the step 11 in the gravity treatment message that current service cell sends.
Particularly, the edge via node sorts to neighbor cell according to the sub-district reselection criterion, select Target cell in conjunction with measurement result then, make the Target cell select as far as possible under the situation that satisfies the sub-district reselection criterion, reduce and current service cell between interference.For example: according to the sub-district reselection criterion 3 neighbor cells are sorted, neighbor cell 3 is optimum candidate target cells, and neighbor cell 1 takes second place, neighbor cell 2 the 3rd.If neighbor cell 3 is the most serious with the disturbance regime of current service cell, can select neighbor cell 3 to be Target cell so; If but neighbor cell 1 is the most serious with the disturbance regime of current service cell, can select neighbor cell 1 for Target cell so, just can take a kind of compromise mode according to concrete disturbance regime.
Step 23, trunk node selection initial service sub-district, edge are Target cell, execution in step 25.
Step 25, edge via node send gravity treatment message to current service cell, comprise in the gravity treatment message carrying out the judged result that gravity treatment is coordinated with Target cell.
Step 24, edge via node are according to the measurement result of the UE of itself and/or its service, judge whether that need carry out gravity treatment with Target cell coordinates, if need carry out gravity treatment with Target cell coordinates, execution in step 26, do not coordinate if do not need to carry out gravity treatment, respectively execution in step 22 and step 27 with Target cell.
Particularly, for example: if the signal quality to Target cell that the UE of the overlapping region of current service cell and Target cell measures is better than the signal quality to Target cell that the edge via node of this overlapping region is measured, then UE can not select the edge via node that service is provided, but the select target sub-district directly provides service, at this moment, behind the edge trunk node selection Target cell, can not bring into play its effect well, in this case, not needing to carry out gravity treatment with Target cell coordinates.Otherwise,, then need to carry out gravity treatment and coordinate with Target cell if the signal quality to Target cell that the UE of the overlapping region of current service cell and Target cell measures is weaker than the signal quality to Target cell that the edge via node of this overlapping region is measured.Need to prove that above-mentioned judgment mode is one embodiment of the present of invention, the present invention is not limited to this a kind of judgment mode.
Step 26, edge via node comprise in this gravity treatment message and need carry out the judged result that gravity treatment is coordinated with Target cell to the gravity treatment message of current service cell transmission at the gravity treatment Indication message.
Step 27, edge via node comprise in this gravity treatment message not needing to carry out the judged result that gravity treatment is coordinated with Target cell to the gravity treatment message of current service cell transmission at the gravity treatment Indication message.
Particularly, because the edge via node must pass through current service cell with communicating by letter of other network nodes, therefore, the edge via node sends gravity treatment message to current service cell, and current service cell is handled according to the judged result of carrying in the gravity treatment message then.
After execution in step 26 or the step 27, continue execution in step 12 again.
In the present embodiment, when judged result for carrying out the gravity treatment universal time coordinated with Target cell, current service cell sends reselection request message to Target cell, Target cell is according to judging whether to allow edge via node gravity treatment to this Target cell again, if allow edge via node gravity treatment to this Target cell, then this Target cell of edge via node gravity treatment is as its current service cell; If do not allow edge via node gravity treatment to this Target cell, then the edge via node is reselected Target cell.When judged result is carried out the gravity treatment universal time coordinated for not needing with Target cell, represent that the Target cell of selecting is improper, the edge via node is reselected Target cell.
In the present embodiment, after the Serving cell gravity treatment of edge via node, interference between interference, UE and the UE between interference between edge via node and the edge via node, edge via node and the UE can both reduce, and can reduce the interference that current service cell is adjacent the sub-district, thereby effectively solve the ICI problem in the LTE_A system with via node.Whether in addition, needed and Target cell is coordinated by the edge relay node judges, the edge via node only reports that judged result gives current service cell, has saved the signaling consumption between edge via node and the current service cell.In addition,, then select the initial service sub-district, do not need the UE of edge via node and service thereof to measure, saved and measured the needed time as Target cell if the current service cell of edge via node is not the initial service sub-district.
Automatically dispose method the 3rd embodiment of the Serving cell of via node
As shown in Figure 3, automatically dispose the flow chart of method the 3rd embodiment of the Serving cell of via node for the present invention, on the basis of technical scheme shown in Figure 1, the edge via node is the select target sub-district under the triggering of current service cell, can also comprise the steps: before the step 11
Step 30, edge via node receive the gravity treatment Indication message that current service cell sends;
Wherein, the gravity treatment Indication message that the edge via node receives the current service cell transmission specifically can comprise two kinds of situations, specifically receive two kinds of situations of the gravity treatment Indication message of current service cell transmission, do not repeat them here referring to edge via node in the last embodiment step 20.
