Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Core concept of the present invention is: in the multi-carrier HSUPA system, for each carrier wave that belongs in same residential quarter, its neighbor cell is identical, like this, may have a plurality of carrier waves with identical same frequency relation.in the multi-carrier HSUPA system, the same frequency relation of carrier wave refer to the main carrier frequency of neighbor cell or auxiliary carrier frequency point identical with the frequency of this carrier wave, utilize this characteristics, network side divides into groups to carrier resource in advance, the carrier wave that will have identical same frequency relation is divided into one group, when needs distribute the HSUPA resource for UE, to belong to the allocation of carriers of same carrier wave working group to UE as far as possible, then the carrier wave working group with the carrier wave that distributes and carrier wave place notifies to base station and UE, so that after this RNC can carry out take carrier wave working group as unit definite with frequency and alien frequencies relation, to reduce the complexity of network side, correspondingly, after UE carries out the measurement of SNPL based on the same frequency of each carrier wave and alien frequencies relation, because the carrier wave that belongs to same carrier wave working group has identical same frequency relation, be that the SNPL measurement result is also identical, like this, the measurement that UE can carry out take carrier wave working group as unit SNPL with report, and do not need to report the SNPL measurement result of each carrier wave, thereby be conducive to reduce the signaling consumption that reports the SNPL measurement result to produce.
Fig. 1 is the flow chart of the embodiment of the present invention one, and as shown in Figure 1, this embodiment one mainly comprises:
Here need to prove, in actual applications, for a plurality of carrier waves of a residential quarter, may exist a plurality of carrier waves to have identical same frequency relation, this SNPL measurement result that will mean these carrier waves is also with identical.Utilize this characteristics, will be at first in this step divide into groups according to the same frequency relation of each carrier wave carrier wave to the base station, to have identical carrier wave with the frequency relation and be divided into one group, in order to after this can carry out take carrier wave working group as unit definite with frequency and alien frequencies relation, correspondingly, the UE measurement that also can carry out based on this SNPL take carrier wave working group as unit with report.
In this step, to configure to UE according to a plurality of carrier waves in the same carrier wave of preferential selection working group, make carrier wave for UE configuration belong to same carrier wave working group as far as possible, like this, because the same frequency of each carrier wave in same carrier wave working group is identical with the alien frequencies relation, correspondingly, in same carrier wave working group, the SNPL measured value of each carrier wave is also with identical, therefore, after this UE measurement that only needs to carry out SNPL as unit take carrier wave working group gets final product with reporting, namely for for a plurality of carrier waves of belonging to of UE configuration of same carrier wave working group, only need to report one time the SNPL measurement result.So just greatly reduce the signaling consumption because reporting the SNPL measurement result to produce.
In this step, after having distributed carrier wave for UE, not only the carrier wave that distributes to be notified to UE and base station, also the carrier wave working group under this carrier wave to be notified to UE and base station, so that after this when RNC need to determine that the same frequency of each carrier wave and alien frequencies concern for UE, can carry out the definite and notice of same frequency and alien frequencies relation as unit take carrier wave working group, in addition, after carrying out the measurements and calculations of SNPL take carrier wave working group as unit according to the same frequency of each carrier wave of RNC notice and alien frequencies relation as UE, can carry out reporting of SNPL measurement result take carrier wave working group as unit.
In this step, it is that those skilled in the art are known that the same frequency of RNC place how to confirm carrier wave and alien frequencies close, and does not repeat them here.
Here need to prove, normally judge with frequency and alien frequencies relation by DPCH place frequency in time division duplex (TDD) system of existing multi carrier wave high-speed downlink grouping access (HSDPA).And for the multi-carrier HSUPA system, UE can not configure DPCH, like this, when UE does not configure DPCH, can't carry out the configuration with frequency and alien frequencies relation.Based on this, the described working frequency points in the present embodiment can adopt following three kinds of methods to determine, cause in some cases can't be to the configuration with frequency and alien frequencies relation due to the dependence to DPCH place frequency to avoid.
1, network side specifies arbitrary frequency that described UE supports as working frequency points in advance.
Particularly, can to specify arbitrary frequency that UE supports be working frequency points to network side making for the UE resource allocation.
2, take the current dominant frequency point of UE as working frequency points.
3, take the semi-static resource of UE or private resource place carrier wave as working frequency points.
In actual applications, can adopt same frequency and the alien frequencies relation of each carrier wave that the indicating means of bit will distribute for UE to notify to UE in step 104, reducing signaling consumption, concrete grammar can for:
Adopt the mode of bit to be designated as the co-frequency neighbor cell information of the carrier wave working group under each carrier wave that described UE distributes in same frequency list in described measurement control message and alien frequencies list.
here, need to prove, in multicarrier system the same frequency relation of carrier wave refer to the main carrier frequency of neighbor cell or auxiliary carrier frequency point identical with the frequency of this carrier wave, same frequency in the employing single carrier and the indicating means of alien frequencies relation only can be indicated the main carrier frequency same frequency relation identical with the frequency of UE carrier wave of neighbor cell, and the auxiliary carrier frequency point that can't the indicate neighbor cell same frequency relation identical with the frequency of UE carrier wave, therefore, here, not only indicate the main carrier frequency same frequency relation identical with the frequency of UE carrier wave of neighbor cell by same frequency list, also indicate the auxiliary carrier frequency point same frequency relation identical with the frequency of UE carrier wave of neighbor cell by the alien frequencies list, auxiliary carrier wave and the same frequency of this HSUPA carrier wave that how many neighbor cells are arranged with each HSUPA carrier wave of notice UE.
After adopting said method to realize configuration to the same frequency of each carrier wave that UE uses and alien frequencies relation, UE is after synchronous and alien frequencies relation is carried out the measurement of SNPL to each carrier wave based on this, can report the SNPL of each carrier wave, and only report the carrier wave SNPL corresponding to working group at each carrier wave place of its use, that is to say, if for UE has configured a plurality of carrier waves that belong to same carrier wave working group, only need to report a SNPL measurement result to get final product, like this, can reduce the expense of interface-free resources.Correspondingly, in base station side, only need to determine same frequency and the alien frequencies relation of each carrier wave working group, and do not need to determine same frequency and the alien frequencies relation of each carrier wave in each carrier wave working group.As seen, the present invention is conserve system resources effectively, is convenient to improve the dispatching efficiency of system.
In sum, these are only preferred embodiment of the present invention, is not for limiting protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
