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 the same sub-district, 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 is meant that the main carrier frequency of neighbor cell or auxiliary carrier frequency point are 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, the allocation of carriers that as far as possible will belong to same carrier wave working group is given UE, then the carrier wave that distributed and the carrier wave working group at carrier wave place are notified to base station and UE, so that after this RNC can be that unit carries out determining with frequency and alien frequencies relation with carrier wave working group, 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, has identical same frequency relation owing to belong to the carrier wave of same carrier wave working group, be that the SNPL measurement result is also identical, like this, UE can be the unit measurement of carrying out SNPL and report with carrier wave working group, and do not need to report the SNPL measurement result of each carrier wave, thereby help reducing the signaling consumption that reports the SNPL measurement result to be produced.
Fig. 1 is the flow chart of the embodiment of the invention one, and as shown in Figure 1, this embodiment one mainly comprises:
Here need to prove that in actual applications, for a plurality of carrier waves of a sub-district, may exist a plurality of carrier waves to have identical same frequency relation, this SNPL measurement result that will then mean these carrier waves is also with identical.Utilize this characteristics, the general at first concerns that according to the same frequency of each carrier wave the carrier wave to the base station divides into groups in this step, to have identical carrier wave and be divided into one group with the frequency relation, so that can be that unit carries out determining with frequency and alien frequencies relation after this with carrier wave working group, correspondingly, UE can be the unit measurement of carrying out SNPL and report with carrier wave working group based on this also.
In this step, to dispose to UE according to a plurality of carrier waves in the same carrier wave of the preferential selection working group, make the carrier wave that disposes for UE belong to same carrier wave working group as far as possible, like this, because the same frequency of each carrier wave concerns identical with alien frequencies in the same carrier wave working group, correspondingly, the SNPL measured value of each carrier wave is also with identical in the same carrier wave working group, therefore, after this UE need be that unit carries out the measurement of SNPL and report getting final product with carrier wave working group only, promptly, only need report one time the SNPL measurement result for for a plurality of carrier waves of belonging to of UE configuration of same carrier wave working group.So just significantly reduce signaling consumption because of reporting the SNPL measurement result to produce.
In this step, after having distributed carrier wave for UE, not only the carrier wave that is distributed 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 determine that the same frequency of each carrier wave and alien frequencies concern for UE, can be that unit carries out determining and notice with frequency and alien frequencies relation with carrier wave working group, in addition, when UE is after unit carries out the measurements and calculations of SNPL according to the same frequency and the alien frequencies relation of each carrier wave of RNC notice with carrier wave working group, can be that unit carries out reporting of SNPL measurement result with carrier wave working group.
In this step, how the RNC place determines that the same frequency of carrier wave and alien frequencies pass are that those skilled in the art are known, does not repeat them here.
Here need to prove that existing multi carrier wave high-speed downlink grouping inserts in time division duplex (TDD) system of (HSDPA) normally to be judged with frequency and alien frequencies relation by DPCH place frequency.And for the multi-carrier HSUPA system, UE can not dispose DPCH, like this, when UE does not dispose 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, to avoid since the dependence to DPCH place frequency cause in some cases can't be to the configuration of same frequency and alien frequencies relation.
1, network side arbitrary frequency of specifying described UE in advance and being supported is as working frequency points.
Particularly, network side is a working frequency points make the arbitrary frequency that can specify UE to support for the UE resource allocation.
2, the current dominant frequency point with UE is a working frequency points.
3, semi-static resource or the private resource place carrier wave with UE is working frequency points.
In actual applications, can adopt the same frequency and the alien frequencies relation of each carrier wave that the indicating means of bit will distribute for UE to be notified to UE in the 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 of described UE distribution in same frequency tabulation in described measurement control messages and the alien frequencies tabulation.
Here, need to prove, the same frequency of carrier wave relation is meant that the main carrier frequency of neighbor cell or auxiliary carrier frequency point are identical with the frequency of this carrier wave in the multicarrier system, adopt the same frequency in the single carrier only can indicate the main carrier frequency same frequency identical of neighbor cell to concern with the frequency of UE carrier wave with the indicating means of alien frequencies relation, 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 by the main carrier frequency of the indication neighbor cell of tabulating with the frequency same frequency relation identical with the frequency of UE carrier wave, also by the auxiliary carrier frequency point of the alien frequencies tabulation indication neighbor cell same frequency relation identical, the auxilliary carrier wave of how many neighbor cells and this HSUPA carrier wave frequency is together arranged with each HSUPA carrier wave of notice UE with the frequency of UE carrier wave.
After adopting the configuration that said method realizes that same frequency and alien frequencies to each carrier wave that UE uses concern, UE based on this synchronously and alien frequencies concern each carrier wave carried out the measurement of SNPL after, can report the SNPL of each carrier wave, and only report the SNPL of carrier wave working group correspondence at each carrier wave place of its use, that is to say, if, then only need report a SNPL measurement result to get final product for UE has disposed a plurality of carrier waves that belong to same carrier wave working group, like this, can reduce the expense of interface-free resources.Correspondingly, in base station side, only need to determine the same frequency and the alien frequencies relation of each carrier wave working group, and do not need to determine the 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, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
