Embodiment
Core concept of the present invention is: for further promoting the TDD power system capacity, introduced the multi-carrier district networking model, caused existing standard can not accurately measure the sub-district.The present invention is when measuring the adjacent sub-district of UE, when determining co-frequency cell, not only that main carrier frequency is identical with the working carrier frequency of UE cell configuration for the assistant carrier frequency adjacent sub-district identical with the working carrier frequency of UE, also disposes in the co-frequency cell information list in the co-frequency cell information list.Like this, the co-channel interference elimination is carried out in the cell information tabulation that UE can directly utilize system to send, and terminal can be obtained adjacent accurately cell carrier frequencies information by the system cell information list.Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
Fig. 1 is the collocation method flow chart of adjacent cell list in the multifrequency cell system of the present invention, and as shown in Figure 1, the collocation method of adjacent cell list may further comprise the steps in the multifrequency cell system of the present invention:
Step 101: initiate adjacent cell measurement control according to the working carrier frequency of user terminal UE.Need to prove, the measurement control of the adjacent sub-district of UE is by radio network controller (RNC, Radio Network Controller) initiates, when the measurement control of initiating the adjacent sub-district of UE, specifically by carry P-CCPCH RSCP in cell measurement control (MeasurementControl) message, Timeslot ISCP initiates, the initiation process of MeasurementControl message is identical with single-frequency carrier networking pattern.
The sub-district of single carrier networking, a carrier wave is only arranged, directly initiate pilot signal sign indicating number power P-CCPCH RSCP by Measurement Control message and get final product, relatively whether identical UE place cell carrier frequencies is with adjacent cell carrier frequencies is that the adjacent sub-district of decidable belongs to " Intra-frequency cell info list " or " Inter-frequencycell info list ".And under overloading networking frequently cell pattern, the situation that adjacent sub-district belongs to " Intra-frequency cell infolist " or " Inter-frequency cell info list " also becomes complicated.Three sub-district A, B, C are for example arranged at present, and they all have three carrier wave: A{f1, f2, and f3}, B{f2, f3, f4}, C{f3, f4, f5}, first carrier wave are their main carriers.If UE is operated on the f3 of sub-district A, when measuring PCCPCH-RSCP, sub-district C belongs to " Intra-frequency cell info list ", and sub-district A and B belong to " Inter-frequency cell info list "; When measuring Timeslot ISCP, sub-district A, B, C belong to " Intra-frequency cell info list ".
For the working carrier frequency of UE, the carrier frequency when promptly being the UE service access, and if UE is in free time (IDLE) pattern, think that then it resides on the main carrier.
Step 102: the adjacent sub-district that main carrier frequency is different with described UE working carrier frequency, be configured in the different frequency cell information tabulation, will contain the adjacent sub-district with described UE working carrier frequency same carrier, be configured in the co-frequency cell information list.
Definite mode about " Intra-frequency cell info list " and " Inter-frequency cell info list " the invention provides dual mode, and first kind of mode is:
RNC at first initiates the Timeslot ISCP of UE place adjacent cells of cells is measured control, determine whether there be the main and auxiliary carrier frequency identical in the adjacent cells of cells of UE place with the working carrier frequency of UE, if there be the carrier frequency identical, then should neighbour's cell configuration arrive in " Intra-frequency cell infolist " with the working carrier frequency of UE.At this moment, existing dominant frequency has auxilliaryly frequently with sub-district frequently again with frequently in " Intra-frequency cell info list ".For making things convenient for the differentiation of UE, initiate P-CCPCH RSCP again and measure control, be that RNC initiation measurement control requires UE that the pilot frequency intensity of place adjacent cells of cells is measured, for the main carrier frequency adjacent sub-district identical in the co-frequency cell tabulation with the UE working carrier frequency, need UE to measure this sub-district master P-CCPCH RSCP sign to its interpolation, promptly add Cells for measurement information, the sub-district of these signs also needs UE to carry out P-CCPCH RSCP measurement; If the main carrier frequency of adjacent sub-district is different with working carrier frequency, then should be configured in the different frequency cell information tabulation neighbour sub-district, these sub-districts all need UE to carry out the P-CCPCHRSCP measurement.If Cells for measurement information is arranged with the sub-district in the tabulation frequently, then can be judged as main carrier frequency with frequently, what do not contain this message is assistant carrier frequency with frequently.
The second way is:
RNC at first initiates the P-CCPCH RSCP of UE place adjacent cells of cells is measured control, determine whether UE place adjacent cells of cells main carrier frequency is identical with the working carrier frequency of UE, the cell configuration that main carrier frequency is identical with the UE working carrier frequency is in " Intra-frequency cell info list ", and need UE to measure this sub-district master P-CCPCH RSCP sign to its interpolation, promptly add Cells for measurement message, the sub-district of these signs also needs UE to carry out P-CCPCH RSCP measurement; If the main carrier frequency of adjacent sub-district is different with working carrier frequency, then should be configured in the different frequency cell information tabulation " Inter-frequency cell infolist " the neighbour sub-district, these sub-districts all need UE to carry out P-CCPCH RSCP measurement.At this moment, " Inter-frequencycell info list " remains in auxilliary sub-district that frequently may be identical with the UE working carrier frequency, initiate Timeslot ISCP again and measure control, find out the frequently identical sub-district of carrier frequency and UE working carrier frequency, find out auxilliary at " Inter-frequency cell infolist " frequently with sub-district frequently and copy in " Intra-frequency cell info list ".Like this, if with the sub-district in the tabulation frequently Cells for measurement message is arranged, then can be judged as main carrier frequency with frequently, what do not contain this message is assistant carrier frequency with frequently.
Handle for convenient, the corresponding cell ID of each adjacent cell configuration for sub-district, UE place, described cell ID is configured among " Intra-frequency cell info list ", " the Inter-frequency cell info list " and gets final product, when UE carries out the co-channel interference elimination according to " the Intra-frequency cell info list ", " the Inter-frequency cell infolist " that receive, carry out cell identification by cell ID.Be convenient and handle that when same adjacent sub-district not only had been configured to the different frequency cell information tabulation but also had been configured in the co-frequency cell information list, cell ID was identical.Certainly, the cell ID difference can realize that also it is higher just to handle complexity, and RNC need store the information of different identification corresponding to a physical area.Definite mode of aforesaid " Intra-frequency cell info list " and " Inter-frequency cell info list ", having under the prerequisite of cell ID, deal with and just be very easy to, and UE can obtain the corresponding relation of adjacent sub-district main carrier frequency, assistant carrier frequency easily.
Step 103: with the configuration information of adjacent cell list is " Intra-frequency cell info list " and " Inter-frequency cell info list " notice UE.The co-channel interference elimination is carried out in the cell information tabulation that UE can directly utilize system to send, and UE can obtain adjacent accurately cell carrier frequencies information by the system cell information list.For the UE of current use dedicated channel (DCH), the configuring condition of adjacent cell list is notified UE by measuring control messages; For the current UE that does not use dedicated channel, notify UE by system message.
